Description

Technical Field

[0001] This utility model relates to the field of auxiliary disassembly and assembly technology of pulleys, specifically an auxiliary disassembly and assembly mechanism for pulleys. Background Technology

[0002] A pulley is a power transmission structure, typically consisting of a driving pulley and a driven pulley, with a belt wrapped around them. When the driving pulley rotates, it drives the driven pulley to rotate via the belt. The center of the driving pulley is mounted on the motor's drive shaft. Specifically, the motor's drive shaft passes through a through hole in the center of the driving pulley, and a nut is screwed onto the end of the motor's drive shaft. This secures the driving pulley, and both the nut and the driving pulley rotate together with the motor's drive shaft. However, removing the nut and driving pulley from the motor's drive shaft requires multiple people, resulting in low efficiency.

[0003] In view of the above problems, this utility model is proposed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an auxiliary disassembly and assembly mechanism for pulleys to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0006] This utility model provides an auxiliary disassembly and assembly mechanism for pulleys, including a bottom pedal, a frame ring provided at the rear end of the upper surface of the bottom pedal, and a plurality of waist-shaped holes penetrating the frame ring on the surface of the frame ring.

[0007] A connecting arm is provided above the surface of the frame ring, and a suspension column is provided at the front end of the connecting arm. The suspension column is located directly above the bottom pedal and is perpendicular to the bottom pedal. A plug rod is horizontally inserted into the lower end of the vertical part of the suspension column.

[0008] The insertion rod is perpendicular to the frame ring, and a hexagonal bolt head is provided at one end of the insertion rod near the frame ring. Multiple slots are provided on the upper surface of the insertion rod.

[0009] The surface of the suspension column is provided with a slider that can slide up and down. The slider is located directly above the slot. The lower surface of the slider is provided with a plug that is inserted into the slot at different positions.

[0010] A base plate is provided on the lower surface of the bottom pedal, and an electric push rod is provided between the upper surface of the base plate and the lower surface of the bottom pedal.

[0011] Preferably, a spring seat is provided on the surface of the suspension column, the spring seat is located directly above the slider, and a spring is provided between the lower surface of the spring seat and the upper surface of the slider.

[0012] Preferably, the surface of the suspension column is provided with a groove, and the back of the slider is slidably mounted in the groove.

[0013] Preferably, the plurality of slots are evenly distributed at equal intervals along the length of the insert rod, and a handle is vertically provided at the end of the insert rod away from the frame ring.

[0014] Preferably, the slider has multiple anti-slip protrusions on its two sides, and the upper surface of the bottom pedal has multiple anti-slip patterns.

[0015] Preferably, the plurality of waist-shaped holes are evenly distributed at equal intervals along the surface of the frame ring.

[0016] Preferably, there are at least two springs symmetrically distributed between the spring seat and the slider;

[0017] Preferably, a base plate is provided on the lower surface of the bottom pedal, and an electric actuator is provided between the upper surface of the base plate and the lower surface of the bottom pedal.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The insertion rod can move back and forth at the lower end of the suspension column, so that the hexagonal bolt head at the front end of the insertion rod can be close to or away from the center of the frame ring; the slider can move up and down on the surface of the vertical part of the suspension column, and the two springs always exert a downward thrust on the slider, so that the plug is just inserted into the slot to fix the position of the insertion rod.

[0020] When you need to move the plug rod back and forth, hold the anti-slip protrusions on both sides of the slider and move the slider upwards. This will move the plug away from the slot. After moving the plug rod to the appropriate position, release the slider. Under the downward pushing force of the spring, the plug will enter the slot and the position of the plug rod will be fixed.

[0021] When using, place the front end of the motor and the drive pulley in the center of the frame ring, so that the oblong hole is aligned with the screw hole on the motor. Use bolts to pass through the oblong hole and screw them into the screw holes around the motor housing. In this way, the motor is installed on the frame ring. At this time, the hex bolt head is aligned with the internal hex nut in the center of the pulley on the motor drive shaft.

[0022] Move the insert rod forward so that the hex bolt head enters the socket head cap nut. The hex bolt head secures the socket head cap nut. At this time, the outer surface of the socket head cap nut is still threaded with a hub nut. After unscrewing the hub nut with a wrench, use a puller to remove the pulley. The disassembly is highly efficient. During the process of unscrewing the hub nut and removing the pulley, you can step on the bottom pedal, which improves the stability of the entire device. The bottom pedal can be raised and lowered using an electric actuator, making it convenient to step on the bottom pedal.

[0023] This device can not only remove the drive pulley mounted on the motor drive shaft, but also remove the drive pulley mounted on other types of flywheels, making it widely applicable. Attached Figure Description

[0030] like Figure 1-3 As shown, an auxiliary disassembly and assembly mechanism for a pulley includes a bottom pedal 1, a frame ring 11 is provided at the rear end of the upper surface of the bottom pedal 1, and a plurality of waist-shaped holes 12 penetrating the frame ring 11 are provided on the surface of the frame ring 11.

[0031] A connecting arm 131 is provided above the surface of the frame ring 11. A suspension column 13 is provided at the front end of the connecting arm 131. The suspension column 13 is located directly above the bottom pedal 1 and is perpendicular to the bottom pedal 1. A plug rod 2 is horizontally inserted into the lower end of the vertical part of the suspension column 13.

[0032] The insertion rod 2 is perpendicular to the frame ring 11. A hexagonal bolt head 21 is provided at one end of the insertion rod 2 near the frame ring 11. Multiple slots 22 are provided on the upper surface of the insertion rod 2.

[0033] The surface of the suspension column 13 is provided with a slider 16 that can slide up and down. The slider 16 is located directly above the slot 22. The lower surface of the slider 16 is provided with a plug 17, which is inserted into the slot 22 at different positions.

[0034] A spring seat 14 is provided on the surface of the suspension column 13. The spring seat 14 is located directly above the slider 16. A spring is provided between the lower surface of the spring seat 14 and the upper surface of the slider 16.

[0035] The surface of the vertical part of the suspension column 13 is provided with a groove 18, and the back of the slider 16 is slidably installed in the groove 18.

[0036] Multiple slots 22 are evenly distributed at equal intervals along the length of the insertion rod 2, and a handle 23 is vertically installed at the end of the insertion rod 2 away from the frame ring 11.

[0037] Multiple anti-slip ridges 19 are provided on both sides of the slider 16, and multiple anti-slip patterns 10 are provided on the upper surface of the bottom pedal 1.

[0038] Multiple waist-shaped holes 12 are evenly distributed at equal intervals along the surface of the frame ring 11.

[0039] There are at least two springs 15, symmetrically distributed between the spring seat 14 and the slider 16.

[0040] In summary: the insertion rod 2 can move back and forth at the lower end of the suspension column 13, so that the hexagonal bolt head 21 at the front end of the insertion rod 2 can be close to or away from the center of the frame ring 11; the slider 16 can move up and down on the surface of the vertical part of the suspension column 13, and the two springs 15 always have a downward pushing force on the slider 16, so that the plug 17 is just inserted into the slot 22 to fix the position of the insertion rod 2;

[0041] When it is necessary to move the plug 2 back and forth, hold the anti-slip protrusions 19 on both sides of the slider 16 and move the slider 16 upwards. This will cause the plug 17 to leave the slot 22. After moving the plug 2 back and forth to the appropriate position, release the slider 16. Under the downward pushing force of the spring 15, the plug 17 will enter the slot 22, fixing the position of the plug 2.

[0042] When in use, place the front end of the motor and the drive pulley in the center of the frame ring 11, so that the oblong hole 12 is aligned with the screw hole on the motor. Use bolts to pass through the oblong hole 12 and screw them into the screw holes around the motor housing. In this way, the motor is installed on the frame ring 11. At this time, the hex bolt head 21 is aligned with the internal hex nut at the center of the pulley on the motor drive shaft.

[0043] Move the insert rod 2 forward so that the hex bolt head 21 enters the internal hex nut, and the hex bolt head 21 fixes the internal hex nut. At this time, the outer surface of the internal hex nut is still threaded with the hub nut. After unscrewing the hub nut with a wrench, the pulley can be removed with a puller. The disassembly efficiency is high. During the process of unscrewing the hub nut and removing the pulley, the bottom pedal 1 can be stepped on, which makes the stability of the whole device better. Furthermore, the bottom pedal 1 can be raised and lowered by the electric push rod 31, which makes it convenient to step on the bottom pedal 1.

[0044] This device can not only remove the drive pulley mounted on the motor drive shaft, but also remove the drive pulley mounted on other types of flywheels, making it widely applicable.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
