Description

Technical Field

[0001] This utility model relates to the technical field of pin removal equipment, specifically to a turnout pin removal device. Background Technology

[0002] Turnout pins are key components in railway turnout systems used to fix and connect various turnout parts. They are usually installed at specific positions on the side of the turnout guide rail to stabilize the turnout structure and ensure the stability of the turnout parts when the train is running. Their materials generally have high strength and wear resistance to adapt to the complexity of the railway operating environment and the high load requirements. However, in practical applications, due to the special position of the turnout pin installed on the side of the turnout guide rail, when using traditional tools to clamp one end of the turnout pin, the end of the turnout pin is usually round and is very easy to slip out. Therefore, it is difficult to disassemble and fix it quickly. To address the aforementioned issues, we propose a fork pin disassembly device. Utility Model Content

[0003] The purpose of this invention is to provide a turnout pin removal device to address the aforementioned shortcomings in the technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a turnout pin disassembly device, comprising a pin positioning sleeve, wherein four equally spaced positioning cylinders are fixedly provided on the bottom side wall of the pin positioning sleeve through an opening, a first hydraulic cylinder is fixedly provided on the inner wall of the positioning cylinder, a first piston plate is slidably connected to the inner wall of the four first hydraulic cylinders, a first push rod is fixedly provided on one outer wall of the first piston plate, a clamping plate is fixedly provided on the outer wall of the other end of the four first push rods, the four clamping plates are located inside the pin positioning sleeve, and two fixing rings are fixedly provided on the outer walls of the top two sides of the pin positioning sleeve, and a second hydraulic cylinder is fixedly provided on the inner wall of the two fixing rings.

[0005] Preferably, the outer wall of the four first hydraulic cylinders away from the clamping plate is fitted with an upwardly curved first pipe joint through an opening. The top outer wall of the pin positioning sleeve is fixedly provided with a hydraulic oil transfer tank. The bottom side wall of the hydraulic oil transfer tank is fixedly provided with four equally spaced liquid guide pipes through an opening. The four liquid guide pipes are respectively connected to the four first pipe joints.

[0006] Preferably, a second pipe joint is fixedly provided at the top center of the hydraulic oil transfer tank through an opening, and anti-slip stripes are provided on one side of the outer wall of the clamp.

[0007] Preferably, the inner walls of the two second hydraulic cylinders are slidably connected with second piston plates, the bottom outer wall of the second piston plates is fixedly provided with a vertically downward second push rod, the bottom outer wall of the second push rod is fixedly provided with a push block, and the bottom outer wall of the push block is bonded with a rubber pad.

[0008] Preferably, the outer walls of the tops of the two second hydraulic cylinders are connected to a connecting pipe through an opening, and the outer walls of the tops of one of the second hydraulic cylinders are connected to a third pipe joint through an opening.

[0009] Preferably, a gripping rod is fixed to the top outer wall of the two second hydraulic cylinders by welding.

[0010] The technical effects and advantages provided by this utility model in the above technical solution are as follows: The pin positioning sleeve can be directly fitted onto the end cap of the turnout pin on the guide rail. A hydraulic device is used to transport hydraulic oil to the hydraulic oil transfer tank. The hydraulic oil in the hydraulic oil transfer tank is transported to the first hydraulic cylinder through the guide pipe. This causes the first piston plate in the first hydraulic cylinder to drive the first push rod to move, thereby enabling the four clamping plates to quickly clamp and fix one end of the turnout pin, preventing slippage during the clamping process. This makes it convenient to use. Attached Figure Description

Then, the pin positioning sleeve 1 is placed on the end cap of the turnout pin to be disassembled. The hydraulic equipment connected to the second pipe joint 10 is started, and the hydraulic oil enters the hydraulic oil transfer tank 8 through the second pipe joint 10, and then flows into the first hydraulic cylinder 3 through the guide pipe 9 and the first pipe joint 7.
