Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a coupling pin disassembly device. Background Art

[0002] In railway transportation, a considerable part of the torque transmission of locomotive equipment adopts the form of coupling. During maintenance work, it is often necessary to separate the connection of the coupling. At present, there are mainly two methods. One is to fix one half of the coupling and use traction equipment to pull the other half of the coupling to separate the two half couplings. This method is limited by the site and equipment and cannot be implemented in many cases. It is time-consuming, labor-intensive and inefficient. The second is to use a hammer tool to forcefully hammer one end face of the coupling pin to withdraw the pin and separate the two half couplings. Most of the pins removed by this method are deformed and scrapped and cannot be used again. In addition, due to the vibration of the hammer, other components are often loosened, which has an adverse effect on the working environment. Summary of the invention

[0003] In order to solve the above-mentioned problems, the present invention proposes a coupling pin disassembly device, which has a simple structure and is easy to use. The coupling pin can be quickly disassembled, thereby protecting the working environment, improving work efficiency, and saving maintenance costs.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions, including:

[0005] A left bracket and a right bracket are mirror-symmetrical, and the upper parts of the left bracket and the upper parts of the right bracket are equipped with guide sleeves. The middle part of the left bracket is provided with a left-handed internal thread, and the middle part of the right bracket is provided with a right-handed internal thread. The left-handed internal thread cooperates with the left-handed external thread of the screw rod, and the right-handed internal thread cooperates with the right-handed external thread of the screw rod. The middle part of the screw rod is fixed with a connecting nut, the lower end of the left bracket is connected to a replaceable boss, and the lower end of the right bracket is connected to a replaceable recess.

[0006] The boss comprises a boss body and a boss pin connected to the boss body. The lower end of the left bracket is connected to a replaceable boss, and the boss pin is embedded in the through hole at the lower end of the left bracket.

[0007] The concave platform comprises a concave platform body and a concave platform pin connected to the concave platform body. The lower end of the right bracket is connected to the replaceable concave platform, and the concave platform pin is embedded in the through hole at the lower end of the right bracket.

[0008] The left bracket, the right bracket, the screw rod, the boss and the concave platform are all made of steel.

[0009] The invention has a simple structure and is convenient to use, and the coupling pin can be quickly disassembled, thereby protecting the working environment, improving working efficiency, and saving maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings to facilitate a clearer understanding by those skilled in the art.

[0017] like Figure 1 As shown, the present invention includes a left bracket 1 and a right bracket 2 which are mirror-symmetrical, the upper parts of the left bracket and the upper parts of the right bracket are equipped with a guide sleeve 3, the middle part of the left bracket is provided with a left-handed internal thread, the middle part of the right bracket is provided with a right-handed internal thread, the left-handed internal thread cooperates with the left-handed external thread of the screw rod 4, the right-handed internal thread cooperates with the right-handed external thread of the screw rod, the middle part of the screw rod is fixed with a connecting nut 5, the lower end of the left bracket is connected to a replaceable boss 6, and the lower end of the right bracket is connected to a replaceable recess 7.

[0018] like Figure 2 , Figure 3 As shown, the boss includes a boss body 6-1 and a boss pin 6-2 connected to the boss body, and the lower end of the left bracket is connected to a replaceable boss by embedding the boss pin into a through hole at the lower end of the left bracket.

[0019] like Figure 4 , Figure 5 As shown, the recessed platform includes a recessed platform body 7-1 and a recessed platform pin 7-2 connected to the recessed platform body. The lower end of the right bracket is connected to a replaceable recessed platform by embedding the recessed platform pin into the through hole at the lower end of the right bracket.

[0020] The left bracket, the right bracket, the screw rod, the boss and the concave platform are all made of steel.

[0021] When in use, unscrew the small nut at the left end of the pin 9, so that the boss body fits with the left end face of the pin, the concave body fits with the right side face of the right half coupling 8, and the right end of the pin is placed in the groove of the concave body, and the nut in the middle of the screw rod is rotated to make the left and right brackets move toward each other. Due to the combined force of the left and right brackets, the pin is pushed out of the left half coupling 10 by the boss body, thereby completing the disassembly work.

[0022] The present invention discloses a coupling pin disassembling device, which has a simple structure and is easy to use, and can quickly disassemble the coupling pin, thereby protecting the working environment, improving working efficiency, and saving maintenance costs.
