SU141495A1 - Attachment to the bulldozer for lateral movement of railway tracks - Google Patents

Description

Known devices for the transverse movement of railway tracks, designed for work in conditions of open pit mining, made in the form of attachments to the bulldozer.

The fixture consists of a support and a hinged frame and a crane boom with a cable-block suspension system and a rail grab mounted on the bulldozer. Such devices are difficult to operate.

In contrast to the known, the proposed device is made in the form of a truss pivoting in a vertical plane with chain slings. The base of the truss is pivotally connected to the horizontal support frame fixed on the back of the tractor-bulldozer, and the apex is connected by a cable-block system with the dump dozer fixture.

The hitch attachment for gripping the track grid can be equipped with an additional hinged frame connected at one end with an iomosh, a valuable hanger with a swing farm, and the other through a hinge with a horizontal support frame of the tractor, nesuply at the free end rigidly shaped rails for the rail.

FIG. 1 shows a general view of the attachment without the hinged frame and with the hinged frame for shifting; in fig. 2 - turning farm; in fig. 3 - support frame; in fig. 4 - hinged frame.

Attachment to the bulldozer for transverse movement of railway tracks (fig. 1a) consists of a rotary truss / made in the form of two beams welded by an angle, the rotary truss is pivotally fixed on the main frame 2, behind the bulldozer and connected by an upper end 3 with cable 4 transferred through block 5 with a blade of a 6 bulldozer. The lower end 7 of the swivel truss / serves for hanging chain slings covering one track of the rail track 8. The cable 4 and the swivel truss / are connected by a spring.

No. 141495- 2 A hinged device for gripping a track grid can also be equipped with an additional hinged frame 9 (Fig. 1 b), which is connected by a hinge at one end to a bulldozer.

The pivot truss / (Fig. 2) includes a stretcher 10 and is a spatial truss, at the upper end 3 of which a spring-loaded shock absorber L is fixed, and at the lower end 7 a stop J2 is fixed. The support frame 2 (Fig. 3) consists of two longitudinal beams 13, fastened with transverse beams M and 15. At the edges, two semi-axes 16 are welded to the beam 15 for a hinged joint with a swing farm /, and in the middle part there is a piercing 16 under the king pin hitch tractor hitch.

The hinged frame (Fig. 4) consists of two curved beams 17, at the end of which is attached an earring 18. From the bottom of the beams there are two pickups 19.

The operation of the attachment (Fig. 1a) is as follows: a bulldozer with a reversing blade raised above the ground approaches perpendicular to the shifted path. By securing the 20 rails with chains, the blade is lowered, and consequently, one thread is lifted. After this production. Dit movement of the blade in reverse tractor, up to 0.5. The blade of the bulldozer is lifted and the track grid is laid on the ground. Sl in the chain of 6 stops 12, the slinger gives the signal for the bulldozer to go to a distance of 10-20 m along the string for repeating the shifting.

The movement of the railway from the bottom occurs in a similar way; only to the turning farm are chains attached to the rail from the side of the bulldozer and the shift of the track occurs when the bulldozer is moving forward.

This adaptation can be used to re-straighten the path with links, with the link being transferred at once to a new installation site.

The fixture allows for work to be carried out on the shifting of the track with significant unevenness of the bottom of the quarry and elevation of the web above the level of the bulldozer station. In the case of a flat bottom of the pit, it is advisable to use a hinged frame (Fig. 16). In this case, the hinged frame 9 is hinged at one end to the tractor, and the second end, with the help of a chain, is connected to a rotary truss 1. In this case, the dozer operates as follows. By lowering the hinged frame on a sliding path, due to the backward movement of the bulldozer, the clamps 19 are brought under the lower end of the rail up to the stop in the struts racks. Further, the string of the track rises and, by slow movement of the bulldozer, moves 0.5 m, then is laid on the ground, and the cycle of operation is repeated. The hinged frame allows one person controlling the bulldozer to move the track, whereas in the first case (without the hinged frame) a second person is required - a slinger.
