Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a Macadam roller provided with a pair of rolls, as front wheels or rear wheels, which are supported by a frame containing a power generation device or the like so as to face each other with the power generation device or the like interposed therebetween. Macadam Laura with improved hood that covers.

[0002]

[Prior art]

 This type of macadam roller is covered with a bonnet so as to cover the entire upper side surface of the power generation device etc. arranged between a pair of opposing rolls, and the end of the vehicle body is covered during inspection and maintenance of the engine. It has a structure that can be opened and closed as a fulcrum.

[0003]

[Problems to be solved by the device]

 In such a structure in which the bonnet covers the entire upper side surface of the power generation device, etc., it is necessary for the operator to ride on the roll and open the bonnet for each inspection and maintenance. Therefore, it was an unstable work on a curved surface, which was extremely dangerous. In particular, workers often work with safety shoes that are hard to feel on the soles of their feet, so if the roll surface gets wet with rain, it is even more slippery and may cause a fall accident. there were. It is an object of the present invention to provide a macadam roller that improves the above-mentioned drawbacks of the conventional bonnet structure and enables safe inspection and maintenance work.

[0004]

[Means for Solving the Problems]

 As a concrete means for achieving the above object, the present invention provides a pair of rolls, which are supported to face each other with the power generation device or the like interposed therebetween, in a frame having a power generation device or the like built therein. A Macadam roller provided as a wheel, characterized in that a hood that covers the power generation device or the like is provided with an auxiliary inspection door that is partially notched and can be opened and closed toward the step installation side. Is proposed.

[0005]

[Action]

 Since the auxiliary inspection door is provided so as to be openable and closable on the side where the step is arranged, the operator can ride on the step and work.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 is a plan view of a macadam roller embodying the present invention, FIG. 2 is a side view of its bonnet portion, and FIG. 3 is a side view of a macadam roller embodying the present invention.

1 to 3, a vehicle body 1 includes front and rear frames 2 and 3 which are articulated to each other. The front frame 2 includes an engine 6, a cooling fan 7, and a hydraulic pump unit 8 as a power generation device therein, and is incorporated as a power generation device 10 including a driving hydraulic motor (not shown). There is. A pair of front rolls 4 and 4 are supported so as to face each other with the power generation device 10 and the like interposed therebetween. The hydraulic energy of the power generator is converted into mechanical energy by a driving hydraulic motor, and drives the front rolls 4 and 4, respectively. The front frame 2 has a front step 9 at its tip. The rear frame 3 has a yoke shape and supports a single rear roll 5.

A bonnet 11 is put on the power generator 10 and covers the entire upper side surface thereof. When performing a comprehensive inspection of the entire power generation device 10 etc., as in the prior art, the bonnet 11 is opened with the front end of the front frame 2 as a fulcrum, as shown by the image line in FIG. An operator rides on the front rolls 4 and 4 to perform work.

A part of the bonnet 11 is cut out as shown by an imaginary line in FIG. 1 to form an auxiliary inspection door 12, and as shown in FIG. 2 and FIG. As a fulcrum, the structure is such that the front step 9 can be opened and closed toward the installation side. Therefore, for the inspection work of the engine 6 and its surroundings, which are often required to be inspected, the operator H (FIG. 3) opens the auxiliary inspection door 12 and vertically fixes the stay 13, and then the front surface which is a flat surface. You can do it by riding on step 9.

In the above example, the pair of rolls 4 and 4 supported so as to face each other with the power generator 10 or the like as the front wheels has been described. Of course, it is applicable.

[0011]

[Effect of device]

 As described above, according to the macadam roller which is an improvement of the bonnet according to the present invention, the bonnet is provided with the auxiliary inspection door which is notched and opened and closed toward the step mounting side. During maintenance, an operator can work on a step with a flat work surface and a low work position without riding on a curved roll as in the past. Therefore, there is almost no risk of a fall accident, there is an effect that it is safe and daily inspections can be performed easily.
