Description

Special crane for grinding wagon

Technical Field

The utility model relates to a special hoist of sanding vehicle belongs to railway crane technical field.

Background

The railway crane is special hoisting equipment for railways, can move along railway lines, undertakes hoisting operation under various environments along the lines, has good maneuverability and adaptability, and is highly valued by various work sections of railways since the railway crane is put into use. With the continuous development of railways and related technologies, railway cranes are also continuously developed, and in China, since the 20 th century and the 50 th century, railway cranes are developed into key hoisting equipment capable of handling railway traffic derailment accidents, eliminating line obstacles and railway construction, and play an extremely important role in ensuring the safe operation of railways and railway construction.

With the higher requirement of our country's economy on the development of the Chinese railway, and the development idea of the railway equipment of "introduction, digestion, absorption, innovation" that the railway ministry put forward, my company developed a medium-sized rail grinding wagon, this car weight is about 8T, and present railway crane can' T satisfy the hoist and mount operation of electrified circuit section, so my company needs to develop a special hoisting machinery, satisfy the hoist and mount operation requirement in electrified circuit section.

Disclosure of Invention

In order to overcome the defects in the prior art, the utility model provides a special crane for a grinding wagon, which has the characteristics of strong bearing capacity, large lifting space, strong adaptability and simple structure. Can bear the lifting work of GMC-12 steel rail grinding vehicles and similar heavy vehicle types.

The utility model provides a technical scheme that its technical problem adopted is: a special crane for a grinding wagon is structurally characterized in that: the upper end of the rail flat car is fixedly provided with a base plate through a long rod bolt, a winch device is arranged in the middle of the base plate, one end of the base plate is provided with a crane upright post, the lower end of the crane upright post is fixedly connected to the base plate through a bolt, and a reinforcing angle iron is fixedly welded at the rear end of the crane upright post; the crane upright column is connected with a crane boom, the rear end of the crane boom is provided with a first pulley, the front end of the crane boom is provided with a second pulley, the lower end of the second pulley is fixedly provided with a steel wire rope, a third pulley is annularly burned by the steel wire rope, and the lower end of the third pulley is connected with a lifting hook; the steel wire rope is connected with the winch device through the pulley II and the pulley I.

The utility model has the advantages that: the GMC-12 steel rail grinding wagon with the bearing weight reaching 8T and similar heavy hoisting work can be carried, the adaptability is strong, the structure is simple, and the hoisting space is large.

Drawings

Fig. 1 is a structural diagram of a crane special for a grinding wagon of the utility model.

In the figure, the crane comprises a rail flat car 1, a rail flat car 2, a long rod bolt 3, a base plate 4, a winch device 5, a reinforcing angle iron 6, a crane upright post 7, a steel wire rope 8, a first pulley 9, a crane boom 10, a second pulley 11, a third pulley 12 and a hook.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

A special crane for a grinding wagon is shown in figure 1, and has the structure as follows: the upper end of the rail flat car 1 is fixedly provided with a base plate 3 through a long rod bolt 2, a winch device 4 is arranged in the middle of the base plate 3, one end of the base plate 3 is provided with a crane upright post 6, the lower end of the crane upright post 6 is fixedly connected to the base plate 3 through a bolt, and a reinforcing angle iron 5 is fixedly welded at the rear end of the crane upright post 6; the crane upright post 6 is connected with a crane boom 9, the rear end of the crane boom 9 is provided with a pulley I8, the front end of the crane boom 9 is provided with a pulley II 10, the lower end of the pulley II 10 is fixedly provided with a steel wire rope 7, the steel wire rope 7 is annularly burned with a pulley III 11, and the lower end of the pulley III 11 is connected with a hook 12; the steel wire rope 7 is connected with the winch device 4 through the second pulley 10 and the first pulley 8.

The hoisting structure adopts a 10T winch as a traction device, and the GMC-12 type steel rail grinding wagon with the weight of 8T can be integrally borne by controlling the hoisting of the winch through remote control. The upward-warping type guide pulley arrangement is adopted, and the shortened double-pulley lifting hook is used, so that the lifting space is improved, and the collision between the GMC-12 type steel rail grinding wagon after lifting and a humpback bottom wagon is effectively prevented.

The electric control system is controlled by AC36V safety voltage, the vehicle is designed with a wireless remote controller without a fixed position for controlling, and an operator can control the winch to move in a traction way to lift the hook. The electric system mainly comprises a control box, a wireless remote controller, an aviation plug, a lighting lamp and the like.

The method comprises the following steps:

1. the GMC-12 type steel rail grinding wagon is fixed by a steel wire rope before being hoisted, and a hoisting machine is controlled by a remote controller to hook the lifting hook and the steel wire rope tightly.

2. The remote controller is controlled to lift the lifting hook to a certain height, so that the bottom of the GMC-12 type steel rail grinding wagon exceeds the plane of the camel-carrying chassis.

3. And connecting the other camel-carrying bottom car with the camel-carrying bottom car of the grinding car crane.

4. The remote controller is controlled to drop the lifting hook, so that the GMC-12 type steel rail grinding wagon is placed on the hump-carrying chassis and is fixed.

5. And (5) dismounting the hoisting device, placing the lifting hook in the original position, and finishing hoisting.
