Detailed Description

In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below with reference to the accompanying drawings and examples.

The lifting device for assembling the train traction hook comprises an assembling supporting mechanism which is assembled and fastened on a train guide rail 1, wherein the assembling supporting mechanism realizes assembling supporting by virtue of the guide rail, and can greatly approach to the traction hook for lifting operation according to the position where the traction hook needs to be overhauled or replaced compared with the current lifting mode of a crane.

On the basis of fixed-point assembled assembly supporting mechanism, the assembly supporting mechanism is provided with a suspension mechanism, the suspension mechanism can realize quick and labor-saving hoisting of the lifting hook, and compared with hoisting by a crane at a long distance, the hoisting state of the traction hook can be intuitively adjusted, so that quick assembly and disassembly are realized.

The assembly supporting mechanism is assembled on the guide rail, and applies a large supporting force to the traction hook by virtue of the guide rail, so that the assembly supporting mechanism can cause certain surface damage to the guide rail in the process of lifting the traction hook, and therefore, in order to solve the problem, one side of the assembly supporting mechanism is provided with the guide rail protection mechanism opposite to the lifting direction, and the problem of contact abrasion between the assembly supporting mechanism and the surface of the guide rail in the process of lifting the traction hook is solved by the guide rail protection mechanism.

Specifically, as shown in fig. 3, the assembly supporting mechanism includes an L-shaped clamping plate 2 clamped and sleeved at two sides of the train guide rail 1 and a flat plate 21 thereon, specifically, the L-shaped clamping plate 2 at one side is fixedly connected with the flat plate 21, the L-shaped clamping plate 2 at the other side is hinged with the flat plate 21, after the hinged L-shaped clamping plate 2 is opened, the assembly and disassembly with the guide rail can be realized, and one side of the flat plate 21 is also provided with a pin hole for locking and positioning the hinged L-shaped clamping plate 2.

The suspension mechanism comprises a support column 3, an inclined support rod 4 and a lifting hook 5 which are sequentially arranged on a flat plate 21, and also comprises a winch and a traction rope. Wherein, the bottom end of the support column 3 is preferably welded on the upper side of the flat plate 21 for fixing. Under the limit of the clamping sleeves at the two sides of the guide rail through the L-shaped clamping plate 2, the smooth hanging operation of the traction hook can be realized through the hanging hook 5 of the hanging mechanism.

Preferably, the support column 3 is divided into a sleeve structure (as shown in fig. 3) which can rotate up and down, so that the assembly position of the traction hook and the train can be adjusted conveniently in a rotating state.

Since the traction hook is horizontally inserted into the end of the train, the traction hook in a lifted state needs to be horizontally moved during the assembly and disassembly processes, and therefore, in order to facilitate the movement, as shown in fig. 3-6, a roller 6 which is attached to the sliding of the train guide rail 1 is embedded into the bottom side of the flat plate. The lifting device can move on the guide rail through the roller 6 (the friction force between the L-shaped clamping plate 2 and the side wall of the guide rail needs to be overcome when the lifting device moves, so that the side wall of the L-shaped clamping plate 2, which is in contact with the guide rail, is preferably arranged to be of a smooth surface structure, so that the contact friction is reduced), the displacement adjustment of the traction hook is realized, and the flexibility of the loading, unloading, alignment and adjustment operation of the traction hook is improved.

The abrasion of the assembly supporting mechanism and the guide rail is specifically as follows: because the L-shaped clamping plate 2 and the roller 6 are contacted with the guide rail on one side, and the traction hooks of the train are positioned between the guide rails on two sides, the lifting acting force of the suspension mechanism is positioned on one side (between symmetrical guide rails, as shown in fig. 6) of the support column 3, and the L-shaped clamping plate 2 and the roller 6 rotate and wear the inner side wall and the outer side wall and the top surface of the guide rail under the action, so that the targeted wear problem is solved, as shown in fig. 3-6, the guide rail protection mechanism is an auxiliary rod 7 hinged on the outer side wall of the support column 3, and the bottom end of the auxiliary rod 7 is horizontally provided with an L-shaped protection plate 8 contacted with the bottom surface and the inner side wall of the train guide rail 1 under the condition that the roller 6 is contacted with the surface of the train guide rail 1;

during assembly, the auxiliary rod 7 and the L-shaped protection plate 8 are hinged to be opened (the state is shown in fig. 5), then the L-shaped protection plate 8 penetrates into the inner side of the guide rail from a gap (shown at a position in fig. 2) between adjacent sleeper, the L-shaped protection plate 8 is attached to the inner side wall and the bottom surface of the bottom side of the guide rail (the guide rail is of an I-shaped structure), then the suspension device is rotated to enable the roller 6 to be attached to the top surface of the guide rail, after the traction hook is lifted by the lifting hook 5 to bear force, the suspension mechanism is inclined towards the symmetrical center of the guide rail (simultaneously, the support column 3 is rotated and inclined towards the inner side), in this state, the support column 3 is reversely held by the auxiliary rod 7 and the L-shaped protection plate 8 through the bottom of the guide rail, so that abrasion caused to the surface and the two side walls of the guide rail by the roller 6 and the L-shaped clamping plate 2 is overcome, and the effective protection is realized.

In order to realize the adjustment of the assembly position of the L-shaped protection plate 8 along with the movement of the roller 6 on the guide rail, the inner side wall of the L-shaped protection plate 8 is preferably processed into a smooth surface structure, so that the contact friction force of the L-shaped protection plate 8 to the bottom side of the guide rail in the movement process of the roller 6 can be reduced, and the whole movement adjustment of the lifting device is facilitated.

The principle of the utility model is as follows: when the operation of hanging the towing hook is carried out, the auxiliary rod 7 and the L-shaped protection plate 8 are hinged and opened at first, then the L-shaped protection plate 8 penetrates into the inner side of the guide rail from a gap between adjacent sleepers, the L-shaped protection plate 8 is attached to the inner side wall and the bottom surface of the bottom side of the guide rail, meanwhile, the L-shaped clamping plate 2 is clamped on the two sides of the guide rail and locked through pins, and the towing hook can be quickly hung through the lifting hook 5.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. The present utility model is subject to various changes and modifications without departing from the spirit and scope thereof, and such changes and modifications fall within the scope of the utility model as hereinafter claimed.
