Description

BACKGROUND OF THE INVENTION The present invention relates to pklnyh machines for working under a vodka using a saw that, through the cynopia sled, receives backward healings through a crypipe and black feed from a motor placed at the adjustable level to bring the saw to the work site. , the skeleton.

On the same FIG. 1 is a side view and sectional view of FIG. 3 on the line / -1; FIG. 2-section of FIG. 1 on line II - //; FIG. 3 is a top view and, respectively, a section of FIG. 1 along the line /// - J //; FIG. 4 and 5 depict, on an enlarged scale, a view and, respectively, sections of the feeding device, with FIG. 5 corresponds to the time of FIG. 1 along the line V-V; FIG. 6 - top view of the machine; FIG. 7 is a front view of a safety device to prevent PI-1 overload; FIG. 8 is a schematic view of the machine and its supporting frame; in fig. 9 shows the reception of bedded spiling of the sheet pile wall.

The proposed saw has the following device.

The arcuate frame consists of two parallel beams 1 and 2 (fig. 1, 2, 3), mating with the help of a heavy transverse part 3 into a single rigid V-shaped whole. On beam 2, chairs 4 for shafts 5 and 6 are reinforced, which serve to rotate the clamping screws 7 and 8. Chairs 4 are carried by bearings 9 for directing thrust 10,

fastener in the third point, formed by an Estule axle and (Fig. 3). A chair 12 is mounted on the beam 1, on which the bearing for the manually rotating shaft 13 and the subsander 14 for the guide rod 15 are fixed. Equally, the chairs 16 are carried along the sub-platform 14 for the guide rod 15. The pipes 10 and 15 are parallel to each other. friend and form guides for caliper. The two chairs 17 each carry a bearing for the lead screw 18 (FIGS. 4, 5), with which the suport is moved either by hand (by means of chal 13) or by automatically turning the device. Soir bar 19; kena with transverse connecting part 3. When the saw is in the starting position, the bar 19 projects slightly forward, so that when the machine is lowered or raised along the shunt pile, the saw blade is protected from damage. Four long bolts 20 (Fig. 1) fasten the frame with two parallel beams 21 from the angular angle. Connected with rods 22 and 23 (Fig. 8) to the surface platform 24. There are therefore two such half-timbered devices, conjugated with each other in such a way that, in order to receive the wall part to be removed, there will remain an open V-shaped horizontal cross section of the space above the head part of the frame. The surface platform 24 (FIG. 8) is sheathed for ease of maintenance with boards and

can be moved with beams with a blunt-walled wall, or your beam is suspended from a lifting device, y. , Eh.ji

On guides. Ta-Ba "-jetrjni46 ((B e" Tca, with the help of four lugs 25, a sled 26, consisting of a V-shaped part with a table-like protrusion 27. U-obrpz: the second tangled salpecks 28 with the help of guides 29 can return back -accessible movement on the slide 26 and is driven to move through the drive rod 30, the crank 31, the shaft 32 with the universal joint 34, and the double lever.

The slide 28 carries an arcuate frame 35 for a saw. For this purpose, four mounting bolts 35 are provided in the cross slide, which are thinned tapering upwards and passing into the wire rope 37 (Figs. 1, 2, 3.5). The frame 35 can be lifted above the ground with the help of the prodigal rope 38 and the winch 39, for example, for the purpose of inspecting or replacing the ail. When lowering, 3a.ma 35 fits, in the correct position to the cross slide 28. At the ends of its lateral sides, frame 35 carries processes 39 and 40 .. between which the saw blade 41 is clamped. Salzzki 26 carry the part 42 that is associated with them for guiding both the cable-laying chamfering cable 43 and the feeding device. A ratchet 44 is connected to the nut 43. The nut 43 freely engages the clamp 45, which forms one piece with the flat swing arm 48 and rotates in part 42. The swing arm 46 is conjugated by means of the drive rod 47 with the cross slide 28 so that when the device is running the end of the shoulder 43 makes a full stroke of the saw. In addition, the swinging arm 46 carries two oppositely positioned spring-loaded dogs 48 and 49 rotating on the axes 50 and 51. Part 42 carries a trunnion 52 for the dog 53 (Fig. 5). Last coupled with a doggie 49 fitted with a fork-shaped thimble with an axis 54 supporting a du1-shaped rod 56, passed through the eyelet 53 of the dog 53. The bottom of the fork 54 has such a FO; 1st and the spring 57 acts such an oapa.iOM on the rod 56 and the dog 49 that when the last position is raised, the dog 33 engages the ratchet 44.

Under normal conditions of operation, in the part 42, the retractable o8 pin protrudes so far that the pawl 49 slides its lower surface along the tipper part of its stroke from left to right (Fig. 5) and is removed from the ratchet 44. With such a free P In a dog 49, dog 53 comes to the ratchet 44 zatsenlechsha. When the shoulder 48 is moved from left to right, the dog 48 moves the ratchet 44, and together with the nut 43, a certain angle. Thus, when the shoulder 43 is retracted on the right side, the dog 49 is initially still uncoupled, then the ratchet is still 44 and the dog 53 is missed until the dog 49 is moved enough left to slip from the 53 tongs into the ratchet neck. 44. Then the dog 53 will be disengaged, and the ratchet 44 will be turned in the opposite direction only to some part of the above angle. This will unload the saw. When the pin 58 is extended, the pawl 49 is not allowed to slide, the pawl 53 will be disengaged, and the pawl 48 and 49 will move the ratchet 44 and the same points in both directions, so that the saw does not feed.

The movement of the pin 58 controls the mechanism shown in FIG. four; 5, 6, and 7. La plank 60, supporting the slide with a sled 26, has a reinforced support pitch 59, reproducing the movement, as a result of this, driving the saw 41 and sasalazok 26. On the plate 59, it can be moved from the outer hook. Articulated with a hook 61 and rotating on the axis 62, the angular lever 63 acts on the rotating on the axis 64 g) pin 65, from the bottom, the end of which is connected to pin 8.

Cloth 4i burner burned with a service, with the finger of a cricopus 66 and shoulder 67, ukr:: on a roller 68, carried by the process 40 bearings. The upper roll of the roller 68 carries a fork-shaped shoulder 69 (FIG. 7), which in turn , with a: sr1; dsgve bolt 71 hook 70. The normal average position of k) yuch 70 is provided by springs 72. too much load of the saw, for example, due to blunting of the teeth or too much thickness of the cut material, saw 4 can produce a permutation of the bill 66 in a downward direction (FIG. 6). Rama 35 is not so tough that it cannot be; and slightly rotate shoulder 67. Following this hook-70, which, when it is moving to the left, can hook up to the hook 61, slipping along the hook 6S, when hovering from left to right, hooks 61, so pin 58 will clear the way for the dog 49, to the feed will be stopped. Only when the hook is free from the movement.1 61, the hook 70 of the 70-44 will again perform its own step: rpsch ;;: e.

The purpose of iiexaHH3Mj shown in FIG. 5, STANDING - in preventing the saw from being overloaded when feeding and clearing its unloading at 66 times. Lead vipt 18 remains i, o the operating time of the stack is not correct, and the nut 43 performs a step rotation. If, at the end of the cutting process, it is required to move it onto the back of the slide 26, then the shaft 13 P) is rotated by hand.

A vertical rod 73 (Fig. 1-.3) is coupled with a sled 26, on which an i.equipped block 75 is reinforced with a sling rope 74. The rope 74 carries a pointer and is mounted on the upper crossbar 24 so that the position of the saw relative to the guide bars g 10 and i5 can be forever defined.

P; 1And breaking the shkuntovyh walls turned out to be advantageous message direct-; and thus the frame with beams 1 and 2, a small slope. 11is.; The eating cuts of ;;) are then and as far as possible, as shown in FIG. 9. The last ra, cut 76. at which the piles 78 and 79 were driven, ends at point 77 and ends at 1; I graze 80, the spikes in it are cut, and the ends of the 78 and 79 edges can be removed. With the full movement of the back t, the slide 26 1. turns) 1 kem, ala i3, and when the saw 4 is withdrawn BS, the device moves

Valevo until then. until the bar 19 is attached to the edge of the pile 80. Then the clamping screws 7 m 8 (or at least one of them) are pulled in, and the shaft 32 is set in motion, whereby the saw is started and the cutting is started in the plane 81 (FIG. . 9). Due to a slight inclination of the guides t g 10, J5, the saw blade cannot fall into plane 77 of the previous cut, due to which the danger of breakage of the saw is eliminated.

The subject of the patent.
