Description

Technical Field

[0001] The invention relates to the field of railway self-dumping car maintenance, and in particular to a railway self-dumping car hinge pin replacement device and an implementation method. Background Art

[0002] Railway transportation is less affected by climate and natural conditions, and has a large transportation capacity and single vehicle loading capacity. It has advantages in terms of regularity and low cost of transportation. In addition, there are many types of vehicles, which makes it possible to carry almost any goods, almost without weight and volume restrictions, which are incomparable to road and air transportation. Railway freight transportation is one of the main modes of modern transportation and one of the two basic modes of transportation for land freight transportation. It occupies an important position in the entire transportation field and plays an increasingly important role. Due to the increase in railway transportation volume of industrial and mining enterprises, enterprises have compressed production costs, and railway operations have exceeded limits. Railway trains have been operating at full capacity, and various train failures are prone to occur, affecting the efficient and stable operation of trains and driving safety.

[0003] The side of a railway self-dumping car is nearly 12 meters long, and is connected to the bottom plate of the car by five hinge pins to form a car body. Due to the long length of the side of the car, the extrusion pressure exerted on the side of the car by the ore in the car during transportation is prone to plastic deformation, and the rotating hinge pin shafts are worn and bent when the car is reset. The hinge pins on the side of the car are severely bent and worn, causing the five pin shafts to be not on the same axis, and the door of the self-dumping car cannot be opened to unload the goods. When inspecting and replacing the hinge pins, multiple people are required to cooperate and use a push rod to replace the anti-deformed car door. In the prior art, employees have the following problems when replacing the hinge pins of a self-dumping car:

[0004] 1. The replacement process of the hinge pin is cumbersome and requires the cooperation of crane operators and maintenance workers, which is labor-intensive and has great safety risks;

[0005] 2. Due to the lack of tools, the folding pin replacement operation cannot be completed quickly, and the maintenance efficiency is low.

[0006] A Chinese patent with patent number CN203649860U disclosed a self-tipping car folding pin set disassembly machine, including a support frame and a platform arranged on the support frame, a cylinder and a guide arranged along the length direction of the cylinder are installed on the platform, the rodless chamber air port and the rod chamber air port on the cylinder are connected to the air source through an air pipe, the rodless chamber of the cylinder takes in air, the piston rod extends, the punch on the piston rod impacts the rivet gun head, and the rivet gun head moves along the guide rod under the guidance of the sliding sleeve, so that the folding pin sleeve is removed or installed from the bucket car folding hanging bearing hole and the folding hole through the rivet gun head, the operation is simple, the work efficiency is high, and manpower is saved.

[0007] During the disassembly process of the self-tipping folding pin set disassembly machine of the above-mentioned patent, only the folding pin position is impacted, disassembled and replaced. After the folding pin is impacted and ejected, the self-tipping folding supported by the folding pin has no fulcrum and needs to be supported by external force. The entire disassembly, maintenance and replacement process is rather time-consuming and laborious. Summary of the invention
