Abstract

The invention relates to lifting equipment. The purpose of the invention is to expand the functionality by allowing the vehicle to be lifted and set in motion on a track that has come off the rails in the mine workings. For this, the crane is equipped with a perpendicularly mounted boom 7 at its end with a cross-bar 10 with sliding parts and a guide 11, additional telescopic supports 17, pivotally connected to the sliding parts of the cross bar 10, and a carriage 12 placed in the guide 11. 4 silt

Description

The invention relates to mechanical engineering, in particular to lifting and transport equipment, and can be used in mine conditions for lifting rolling stock that has derailed from a rail and in repairing mine installations.

The purpose of the invention is to expand the functionality by allowing the vehicle to be lifted and set in motion on a track that has come off the rails in the mine workings.

Figure 1 shows the crane in the position of lifting and setting the vehicle on the rails; figure 2 - the same, in the transport position; in FIG. 3, view A in FIG. 1; figure 4 - view B in figure 1.

A crane contains a self-propelled frame 1, a turntable 2 on which is mounted by means of hydraulic cylinders 3, 4 and a gate 5 of a box with an arrow 7. The turntable 2 is connected pivotally to a self-propelled frame 1 by means of a turn hydraulic cylinder 8. Box 6 and

the boom 7 is pivotally connected by a hydraulic cylinder 9. The boom 7 end is provided with a transverse traverse 10, made on the traverse of the guide 11, and the carriage 12. The carriage 12 and the guide 11 are connected with the possibility of moving the carriage 12 along the guide 11 pivotally by means of the hydraulic cylinder 13. Retractable parts 14 the traverse 10 is pivotally connected by means of the levers 15 and hydraulic cylinders 16 with additional telescopic supports 17. The sliding parts 14 and the traverse 10 are connected by hydraulic cylinders 18. On the self-propelled frame 1, the grippers 19 are mounted, and the trolley 20 has a reach vayut ropes 21 fixed to the carriage 12, thus mounted on the frame 22 maslostantsip.

Crane works as follows.

When lifting the trolley 20, descended from the rail in the mine workings, the crane is transported to the scene of the accident. Having connected the oil station 22 to the contact shaft electrical network, with the help of a remote control unit

(not shown) hydraulic cylinders 3 and 4, the boom 7 is installed at the required height parallel to the base of the mine workings. Then, pulling the boom 7 out of the box 6 by the hydraulic cylinder 9 and turning it to the required angle by the hydraulic cylinder 8. using the hydraulic cylinders 16, 18 install additional telescopic supports 17 in a vertical position to the required width. Having installed the rail clamps-stops 19, the trolley 20 is connected by ropes 21 to the carriage 12. With the help of hydraulic cylinder 3 and additional telescopic supports 17 the trolley 20 is raised to the required height, the hydraulic cylinder 13 moves the trolley 20 to the required height, the hydraulic cylinder 13 moves the carriage 12 with trolley 20, perpendicular to the axis of the track by the required amount, and additional telescopic supports 17 lower it onto the rail heads. At the end of the work, the cables 21 are removed, the rods of the additional telescopic supports 17 are pulled in, and the hydraulic cylinders 16 place them horizontally in the transport position. The arrangement of the traverse 10, the sliding parts 14 of which are hingedly connected with the additional telescopic supports 17 and the carriage at the end of the boom 7, allows reducing the length of the boom 7, driving the boom 7 into the space between the roof of the mine working and the wagon

20, which came off the rails, move the carriage 12 to the trolley 20 at a time by the required amount to install it on the rails and reduce the loads acting on the self-propelled frame 1 and the boom 7. Most of the cargo is taken by the yoke 10 with additional telescopic supports 17.

Claims (1)

Claims of the invention. A crane containing a chassis, a frame mounted on it with a turntable, mounted on it by means of upwardly hydraulic cylinders, a retractable boom and telescopic supports mounted on the frame, which also have a “, that, in order to expand the functionality by providing the possibility of lifting and setting on the path of a vehicle that has derailed in the mine workings, it is equipped with an installed perpendicular arrow on its end part with a cross member with sliding elements and a guide, additional telescopic supports installed so that they can be rotated in a vertical longitudinal plane and fixing the crosshead on the free ends of the sliding elements, and a carriage placed with in a guide rail that can be reciprocated along the latter.
