JP 2000-336609 A

  In a compacting machine, there are a case where a simple daily inspection is performed on equipment stored in a hood and a case where equipment is removed due to wear or failure. For example, a battery, a V-belt, and the like need daily inspections such as a liquid amount inspection and a tension inspection, but need to be removed from the machine body when they are consumed or broken. And although the former work does not require much work space, in the latter work, it is desirable that the hood is completely removed to secure a wide work space.

  To deal with this problem, the open / close structure shown in FIG. 7 in which the hood is removed each time it is opened is suitable for the latter work, but it is easy for the operator to feel that the frequently used former work is a troublesome structure. On the contrary, the structure for opening and closing the hood around the hinge described in Patent Document 1 is suitable for the former work, but is not suitable for the latter work requiring a large work space because it is not a structure that allows the hood to be completely removed. Cheap.

  The present invention was created to solve such problems, and provides a hood opening and closing structure in a compacting machine capable of selectively using different hood opening and closing modes in accordance with the work purpose of a stored device. The purpose is that.

  In order to solve the above-described problems, the present invention has a support shaft attached to one of the hood and the machine body via a mounting bracket, and on the other side, the support shaft is rotatably held, and the support shaft is moved from the radial direction. A clamp made of a leaf spring having a detachable opening and a misalignment prevention member having a groove through which the support shaft held by the clamp is inserted are attached, and the hood rotates the support shaft held by the clamp. A hood that can be opened and closed as a center and that can be removed by pulling it out of the opening of the clamp and the misalignment prevention member that the support shaft has expanded by elastic deformation, and the support shaft is clamped by the clamp. When an external force other than the removal direction is applied, the hood position shift in the radial direction of the support shaft is prevented by the contact between the support shaft and the groove of the position shift prevention member. Positional deviation of the over de is characterized in that the arrangement is prevented by abutment of the displacement prevention member and the mounting bracket.

According to the said structure, by providing the clamp which consists of leaf | plate springs, for example in the case of daily inspection work of storage equipment, a hood can be opened around a spindle and work can be performed easily, and wide work, such as removal work of storage equipment, etc. When space is required, the hood can be completely removed for work. It is not necessary to use a tool or the like when removing the hood, and the removal work can be performed quickly and easily.
Further, by providing the position shift prevention member, it is possible to prevent the position shift of the hood even when a large external force other than the removal direction is applied to the hood, thereby preventing the plastic deformation or breakage of the clamp.

  Further, the present invention is characterized in that a storage pocket for storing documents of the compacting machine is provided on the inner surface side of the hood.

  According to the said structure, since the document of the compacting machine is accommodated in the inner surface of a hood, the rainproof function and dustproof function with respect to a document are exhibited with a simple structure.

  In the present invention, the hood has a substantially horizontal upper surface portion and a substantially vertical side surface portion in a closed state, and the storage pocket is a corner portion between the upper surface portion and the side surface portion of the hood. It consists of a housing | casing which has a guide board part which inclines so that it may oppose and extends toward a side part.

  According to this configuration, even when the width of the document does not fit within the width of the hood, when stored in the storage pocket, the one end of the document bends gently along the guide plate due to its own weight, Accordingly, it is possible to easily store the document on the inner side of the hood in order to increase the storage width.

  In the present invention, the compacting machine is a hand guide roller, and when the hood is closed, the document stored in the storage pocket is regulated at one end by the side portion side, and the other end is hand guide roller. By being regulated by the lifting hook side, sliding from the storage pocket is prevented.

  According to this configuration, when the hood is closed, the lifting hook or the bracket functions as a lid for the storage opening of the storage pocket. Thereby, even when the body of the hand guide roller is tilted by compaction construction on an inclined ground, or even when the body is vibrating due to unevenness of the ground, it is possible to prevent the documents from slipping out of the storage pocket.

  According to the present invention, different open / close modes of the hood can be used properly according to the work purpose for the accommodated equipment.

  Hereinafter, the form which applied this invention to the hand guide roller is demonstrated. In FIG. 1, a hand guide roller H has a traveling machine body (machine main body) 1 mounted with an engine E as a traveling drive source and a hydraulic pump (not shown) driven by the engine E. Reference numeral 2 denotes a horizontal equipment mounting plate on which the engine E, its associated equipment, a hydraulic pump, and the like are placed, and is a member constituting a part of the traveling machine body 1. A pair of front and rear rolls 3 are mounted on the lower portion of the traveling machine body 1, and each is equipped with a traveling hydraulic motor (not shown) that operates by receiving pressure oil supplied from a hydraulic pump. The operator operates the lever (not shown) provided at the tip of the operation rod 4 to run the hand guide roller H.

  As shown in FIG. 1 (b), an engine E is laid out on one side across the center of the hand guide roller H in the vehicle width direction above the device mounting plate 2, and a battery 5 and a traveling system transmission member ( Equipment having relatively high inspection frequency is laid out such as a vibration transmission member (pulley 7a, V belt 7b, etc.) for vibrating the roll 3 and the pulley 6a, V belt 6b, etc. The hood 8 is attached to the traveling machine body 1 so as to cover the battery 5, the pulleys 6a and 7a, the V belts 6b and 7b, and the like. The hood 8 is made of a plate-like member having an L-shaped cross section having a horizontal upper surface portion 8a and a vertical side surface portion 8b in the closed state, and is made of, for example, a steel plate. A pair of handles 17 are attached to the upper surface portion 8a, and a resin lock screw 18 for locking the closed hood 8 is attached. A lifting hook 19 for hanging a crane hook or the like is attached to the equipment mounting plate 2, and a lock screw 18 that can be turned by hand without requiring a tool with respect to the bracket 20 fixed to the lifting hook 19. The closed state of the hood 8 is locked by screwing. The lock screw 18 of this embodiment employs a plastic head with a large pentagonal knob so that it can be turned by hand.

  A pair of support shafts 9 are provided on the inner surface side lower edge of the side surface portion 8 b of the hood 8 with a space in the vehicle front-rear direction. Each spindle 9 is attached to the hood 8 via a mounting bracket 10. As shown in FIG. 5, the mounting bracket 10 has a U-shaped cross section, and the bottom portion 10 a is applied to the inner surface of the side surface portion 8 b of the hood 8 and is fastened and fixed by the bolt 11 and the nut 12. The support shaft 9 is spanned across the opposing wall portions 10b and 10b, and functions as a rotation shaft of the hood 8 along the vehicle front-rear direction.

  On the other hand, a pair of support plates 13 project from the one side edge of the device mounting plate 2 toward the hood 8 with an interval in the vehicle front-rear direction, and each support plate 13 has a configuration as shown in FIG. In addition, the support shaft 9 is rotatably held by the holding portion 14a and the support shaft 9 is formed of a leaf spring in which an opening portion 14b in which the support shaft 9 is detachable from the radial direction is formed, and the support shaft 9 held by the clamp 14 And a misregistration prevention member 15 having a groove 15a through which is inserted. The support plate 13 is a highly rigid member such as a thick steel plate.

  The clamp 14 is made of, for example, bent spring steel, and is opposed to each other from both sides of the flat bottom portion 14c and the central flat bottom portion 14c that are applied to the upper surface of the support plate 13 and fastened and fixed by the hexagon socket bolts 16. Thus, it has a shape having rising portions 14d and 14d that rise up. The middle part of each rising part 14d is bent and formed in an arc shape so as to hold the outer peripheral surface of the support shaft 9 from both sides as the holding part 14a. And the opening part 14b is formed above the clamping part 14a.

  The displacement prevention member 15 is fixed to the edge of the support plate 13 by welding or the like so as to stand next to the clamp 14, and as shown in FIG. The position shift prevention member 15 closer to the rear of the vehicle than the clamp 14 is positioned closer to the front of the vehicle than the clamp 14. Similarly to the support plate 13, the misalignment prevention member 15 is also composed of a highly rigid plate member such as a thick steel plate. As shown in FIG. 2, the misregistration preventing member 15 is formed with a U-groove having an open top as the groove 15a. As shown in FIG. 4, the support shaft 9 in the state of being held by the holding portion 14a is inserted around the bottom of the groove 15a, and at that time, a slight gap is formed between the support shaft 9 and the wall surface around the bottom of the groove 15a. Is formed. In FIG. 5, in a state where the support shaft 9 is clamped by the clamp 14, the wall portion 10 b of the mounting bracket 10 is located behind the position deviation prevention member 15 near the front of the vehicle with a slight gap therebetween. The wall 10b of the mounting bracket 10 is positioned with a slight gap in front of the near-position displacement prevention member 15.

"Action"
In a normal state, the hood 8 opens and closes around the support shaft 9 clamped by the clamping portion 14a of the clamp 14 as a rotation center. When the hood 8 in the closed state (the state shown in FIG. 3A) is opened, the lock screw 18 that can be turned by hand without using a tool is removed, and then the handle 17 is pulled to rotate the hood 8. In the present embodiment, as shown in FIG. 3B, the bottom portion 10 a of the mounting bracket 10 abuts against the bottom corner of the misalignment prevention member 15, thereby preventing further rotation of the hood 8. Yes. The rotation angle of the hood 8 is about 30 degrees.

  Then, when the handle 17 is pulled upward against the clamping force of the clamping part 14a due to the elasticity of the leaf spring, the opening part 14b expands, so that the support shaft 9 and the groove part of the opening part 14b of the clamp 14 and the displacement prevention member 15 are expanded. The hood 8 is completely removed from the traveling machine body 1 by escaping from 15a.

  Next, when a large external force other than the removal direction is applied to the hood 8 in a state where the support shaft 9 is clamped by the clamp 14, that is, when a large external force other than the removal direction is applied to the support shaft 9. The supporting shaft 9 cannot be supported only by the clamping force of the clamp 14 made of a leaf spring, and the hood 8 is likely to be displaced. However, according to the present invention, since the misalignment prevention member 15 is provided, the misalignment of the hood 8 in the radial direction of the support shaft 9 causes the support shaft 9 to contact the wall surface of the groove 15a of the misalignment prevention member 15. Is blocked by.

  Further, the positional deviation of the hood 8 with respect to the axial direction of the support shaft 9 is prevented by the mounting bracket 10 coming into contact with the positional deviation preventing member 15. Specifically, in FIG. 5, when an external force applied to the front of the vehicle is applied to the hood 8, the wall portion 10 b of the mounting bracket 10 positioned closer to the front of the vehicle comes into contact with the rear surface of the misalignment prevention member 15. When the forward displacement of the vehicle is prevented and an external force is applied to the hood 8 toward the rear of the vehicle, the wall portion 10b of the mounting bracket 10 located closer to the rear of the vehicle comes into contact with the front surface of the displacement prevention member 15. The position shift of the hood 8 toward the rear of the vehicle is prevented.

  According to the present invention, the clamp 14 made of a leaf spring is provided, so that the hood 8 can be attached to the support shaft 9 for routine and simple work such as checking the amount of the battery 5 and checking the tension of the V-belts 6b and 7b. The work can be performed by opening it around, and in the case of work that requires removal of the device such as replacement of the battery 5 or the V-belts 6b and 7b, the work can be performed with the hood 8 completely removed and a large work space. . Since it is not necessary to use a tool or the like when the hood 8 is attached / detached, the attaching / detaching operation can be performed quickly and easily.

  Further, by providing the misalignment prevention member 15, misalignment of the hood 8 can be prevented even when a large external force is applied to the hood 8 in the direction other than the removal direction, and hence plastic deformation or breakage of the clamp 14 can be prevented. .

  Next, in recent years, compaction machines are often used in rental form and are used by an unspecified number of people, so it is desirable that documents such as instruction manuals for compaction machines be directly attached to the machine body. Therefore, in the hand guide roller H of the present embodiment, as shown in FIG. 6, a storage pocket 21 for storing a document S such as an instruction manual of the hand guide roller H is provided on the inner surface side of the upper surface portion 8 a of the hood 8. Is provided. The compaction machine document S includes a warranty card, a maintenance inspection record book, a safety manual, etc. in addition to the instruction manual.

  A pocket housing plate (housing) 22 having a U-shaped cross section with an open top is attached to the inner surface of the upper surface portion 8 a of the hood 8, and is surrounded by the inner surface of the upper surface portion 8 a of the hood 8 and the pocket housing plate 22. The space thus formed constitutes the pocket space of the storage pocket 21. When storing the document S, the document S is inserted into the storage pocket 21 from the center in the vehicle width direction of the hand guide roller H with respect to the opened hood 8. As described above, according to the present invention, since the document S is stored on the inner surface of the hood 8, the rainproof function and the dustproof function of the document S are exhibited when the hood 8 is closed. The document S may be stored in the storage pocket 21 without being exposed, or may be stored in a resin bag or a resin case.

  Here, the document S such as the instruction manual is often A4 size, but the hand guide roller H is relatively small and has a narrow body width, and the center of the body for hanging the truck on the loading platform. Further, since the lifting hooks 19 are laid out, it is difficult to fit the A4 size document S in the space half the body width. On the other hand, in this embodiment, the guide plate part 22a inclined toward the lower side is formed at the edge of the pocket housing plate 22 facing the side surface part 8b of the hood 8. That is, the guide plate portion 22a is inclined so as to face the corner portion between the upper surface portion 8a and the side surface portion 8b of the hood 8 and extends toward the side surface portion 8b. Thereby, for example, even when the width in the A4 size lateral direction (short direction) of the document S does not fit in the width dimension in the hood 8, when the document S is stored in the storage pocket 21, one end of the document S is caused by its own weight. The document S can be easily stored on the inner surface side of the hood 8 in order to bend gently along the guide plate portion 22a and increase the storage width accordingly.

Further, in the present embodiment, when the hood 8 is closed, the document S stored in the storage pocket 21 has one end restricted by the side surface portion 8b side and the other end restricted by the lifting hook 19 side. The sliding from the storage pocket 21 is prevented. For example, even if the document S is displaced in the lateral direction, one end in the lateral direction hits the side surface portion 8b and the other end contacts the bracket 20 described above, thereby preventing further displacement in the vehicle width direction. ing. That is, when the hood 8 is closed, the bracket 20 functions as a lid for the storage opening of the storage pocket 21. Thereby, even when the machine body of the hand guide roller H is tilted by compaction construction on an inclined ground or when the machine body vibrates due to unevenness of the ground, the slip of the document S from the storage opening of the storage pocket 21 is caused. Can prevent falling. When the document S is required, the hood 8 is rotated around the support shaft 9 and the hood 8 is opened so that the storage opening of the storage pocket 21 is opened upward. S can be taken out.
When the hood 8 is closed, the other end of the document S may be brought into direct contact with the lifting hook 19 instead of the bracket 20 to prevent the document S from sliding down.

  The preferred embodiment of the present invention has been described above. In the described embodiment, the support shaft 9 is attached to the hood 8, and the clamp 14 and the misalignment prevention member 15 are attached to the traveling machine body 1, but conversely, the support shaft 9 is attached to the traveling machine body 1 and the clamp 14 is attached to the hood 8. The misalignment prevention member 15 may be attached. However, as in the embodiment described, the structure in which the support shaft 9 is attached to the hood 8 and the clamp 14 and the misalignment prevention member 15 are attached to the traveling machine body 1 has the detaching direction (detaching direction) of the hood 8 in one direction. This is advantageous because it is easy for the operator to understand how to attach and detach the hood 8. Further, the present invention is not limited to the hand guide roller but can be applied to other compaction machines. In addition, the layout, shape, number, and the like of each component are not limited to those described in the drawings, and the present invention can be implemented.
