A wheel and axle pulling tool

Abstract

This utility model relates to the field of wheel and axle disassembly technology and discloses a wheel and axle pulling tool, including a fixed base. An external threaded sleeve is welded to the right side of the fixed base. A pulling pin is provided inside the external threaded sleeve. A limiting opening is formed inside the pulling pin. The right end of the pulling pin extends to the outside of the right end of the external threaded sleeve. The left end of the pulling pin extends into the fixed base and is welded with a pin-pulling head.

This method facilitates quick removal of the T-shaped wheel and axle, reducing the difficulty of disassembling it.

Description

Technical Field

[0001] This utility model relates to the field of wheel and axle disassembly technology, and more specifically to a wheel and axle pulling tool. Background Technology

[0002] Currently, the maintenance and upkeep of cableway equipment mainly involves regular inspections and measurements of components prone to friction and wear. The operating status of the cableway is assessed by analyzing standard data. Timely and proper maintenance can prevent equipment damage and reduce repair costs. A common area of ​​focus is the cableway support system's sheave assembly, which supports almost the entire cableway load and transports passengers; therefore, ensuring it remains in good working order is crucial. The line equipment operates in a natural environment for extended periods, and the wheel bushings of the line support wheelset require periodic replacement due to wear. The specific workflow involves first removing the severely worn wheels from the line support wheelset and replacing them with well-maintained spare wheels.

[0003] Currently, the wheel axle and the bracket fixing side plate are prone to excessive deformation and friction, making disassembly difficult. Typically, a slightly thinner "bullet-shaped" tool is installed inside the axle, and the axle is removed by forceful impact combined with a homemade impact puller on the outside of the wheel. However, if the axle is too tight, these tools alone are insufficient and time-consuming to remove it manually. Therefore, we are designing a wheel axle pulling tool. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wheel and axle pulling tool to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a wheel and axle pulling tool, including a fixed base, an external threaded sleeve welded to the right side of the fixed base, a pulling pin provided inside the external threaded sleeve, a limiting port opened inside the pulling pin, the right end of the pulling pin extending to the outside of the right end of the external threaded sleeve, the left end of the pulling pin extending into the fixed base and welded with a pin head, symmetrical track grooves opened on the upper and lower sides of the external threaded sleeve, a pin provided inside the track groove, the bottom end of the pin penetrating the limiting port and extending to the bottom of the external threaded sleeve, a large nut threadedly connected to the outer wall of the external threaded sleeve, a pressure bearing movably sleeved on the outer wall of the external threaded sleeve, the pressure bearing located between the pin and the large nut, the left side of the pressure bearing being embedded in the right side of the large nut.

[0006] Furthermore, a hook wrench is provided in front of the external threaded sleeve, and the interior of one end of the hook wrench is located on the outer wall of the large nut.

[0007] Furthermore, the outer diameter of the external threaded sleeve is 60mm, the length is 200mm, and the inner diameter is 44mm.

[0008] Furthermore, the track groove has a width of 10mm and a length of 145mm.

[0009] The technical effects and advantages of this utility model are as follows: 1. This utility model uses a pull pin head to hook the T-shaped axle of the wheel. By rotating the large nut, the pin is moved, which in turn pushes the pull pin and the pull pin head to move, thereby pulling out the T-shaped axle. This method facilitates the quick removal of the T-shaped axle and reduces the difficulty of disassembling it. Attached Figure Description

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The wheel and axle pulling tool involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1: like Figure 1-5As shown, a wheel and axle pulling tool includes a fixed base 1. An externally threaded sleeve 2 is welded to the right side of the fixed base 1. The externally threaded sleeve 2 has an outer diameter of 60mm, a length of 200mm, and an inner diameter of 44mm. A pulling pin 3 is provided inside the externally threaded sleeve 2. A limiting opening 31 is formed inside the pulling pin 3. The right end of the pulling pin 3 extends to the outside of the right end of the externally threaded sleeve 2, and the left end of the pulling pin 3 extends into the fixed base 1 and is welded with a pulling head 32. Track grooves 21 are symmetrically formed on the upper and lower sides of the externally threaded sleeve 2, with a width of 1... The external threaded sleeve 21 has a diameter of 0 mm and a length of 145 mm. The inside of the track groove 21 is provided with a pin 4. The bottom end of the pin 4 passes through the limiting port 31 and extends to the bottom of the external threaded sleeve 2. The outer wall of the external threaded sleeve 2 is threaded with a large nut 6. The outer wall of the external threaded sleeve 2 is movably sleeved with a pressure bearing 5. The pressure bearing 5 is located between the pin 4 and the large nut 6. The left side of the pressure bearing 5 is embedded in the right side of the large nut 6. The pressure bearing 5 is of model UC206. A hook wrench 7 is provided in front of the external threaded sleeve 2. The inside of one end of the hook wrench 7 is located on the outer wall of the large nut 6.

[0018] In this embodiment, the bottom end of the pin 4 can penetrate the interior of the track groove 21 and the limiting port 31, restricting the pull pin 3 inside the external threaded sleeve 2. When the large nut 6 moves spirally, the large nut 6 can drive the pin 4 to move inside the track groove 21 through the pressure bearing 5. The track groove 21 can guide the pin 4 to slide. The pin 4 can also push the pull pin 3 and the pin puller head 32 to move. The pin puller head 32 pulls the T-shaped wheel axle out of the wheel, thereby quickly disassembling the T-shaped wheel axle.

[0019] In summary, as Figure 1-5 As shown, this axle puller is used by first moving the puller pin 3. The left end of the puller pin 3 drives the puller head 32 to hook onto the end of the T-shaped axle. At this time, the external threaded sleeve 2 is held in one hand, and the hook wrench 7 is used in the other hand to drive the large nut 6 to rotate. The large nut 6 pushes the pin 4 through the pressure bearing 5. The pin 4 simultaneously pushes the puller pin 3 and the puller head 32 to move. The puller head 32 pulls the T-shaped axle out of the wheel, thereby quickly disassembling the T-shaped axle.
