Description

Technical Field

[0001] This utility model relates to the field of wheel pullers, and more particularly to electro-hydraulic wheel pullers. Background Technology

[0002] During equipment maintenance or replacement, workers often need to remove pulleys, gears or other rotating parts from the motor shaft to smoothly and safely separate the rotating parts from the motor. Traditionally, when removing pulleys, workers usually use tools such as wrenches to pry the rotating parts to detach them from the motor shaft.

[0003] Currently, the most common method for removing wheels in repair workshops usually requires 2-3 people to work together using tools such as wrenches. This requires operators to exert a lot of physical strength, which can easily lead to muscle fatigue and injury, and also reduces the efficiency of wheel removal in the workshop.

[0004] Therefore, to address the issue of manually removing wheels using tools such as wrenches, an electro-hydraulic wheel puller can be designed. By setting the wheel puller to be electro-hydraulic driven, the traditional manual wheel pulling method can be eliminated, thus facilitating the solution of the aforementioned problems. Utility Model Content

[0006] The technical solution of this utility model is as follows: an electric hydraulic puller, including a puller body, a carriage, a lifting support plate, a pulling clamp mechanism, and a top-pin mechanism; the lower end of the puller body is provided with a lifting support plate for raising and lowering the height of the puller body, and below the lifting support plate is a carriage for moving the puller body; the front end of the puller body is provided with four sets of pulling clamp mechanisms for fixing the axle wheel, the four sets of pulling clamp mechanisms are arranged around the front end of the puller body, and a top-pin mechanism for holding the mandrel is provided between the four sets of pulling clamp mechanisms.

[0007] Preferably, this application combines a puller body, a carriage, a lifting support plate, a puller mechanism, and a top-pile mechanism, so that during operation, the operator first moves the puller body to a suitable position using the carriage, then adjusts the height of the puller body to a suitable position using the lifting support plate, then fixes the puller wheel to be pulled out using four sets of puller mechanisms, and then uses the top-pile mechanism to hold the motor shaft, while the four sets of puller mechanisms and the top-pile mechanism exert opposite forces to pull the puller wheel out of the motor shaft.

[0008] Preferably, the front end of the puller body is provided with four sets of rotating grooves, and the two side walls of the four sets of rotating grooves are provided with rotating holes. A push hole is provided through the center of the puller body.

Universal wheels are provided at the bottom corners of the vehicle platform, and a push handle is provided at the rear end of the vehicle platform.

[0014] The beneficial effects of this utility model are as follows: Compared with the traditional manual wheel pulling, this application achieves mechanized wheel pulling by combining the pulling clamp mechanism and the top pile mechanism, reducing the need for manpower. Usually, only one person is needed to operate it, which greatly improves the efficiency of wheel pulling and avoids the need for operators to exert a lot of physical strength, thereby reducing the risk of muscle fatigue and injury.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment of an electric hydraulic puller, including a puller body 4, a carriage 1, a lifting support plate 2, a puller clamping mechanism 5, and a top-pinning mechanism 6; the lower end of the puller body 4 is provided with a lifting support plate 2 for raising and lowering the height of the puller body 4, and the carriage 1 for moving the puller body 4 is provided below the lifting support plate 2; the front end of the puller body 4 is provided with four sets of puller clamping mechanisms 5 for fixing the axle wheel, the four sets of puller clamping mechanisms 5 are arranged around the front end of the puller body 4, and the top-pinning mechanism 6 for pressing the mandrel is provided between the four sets of puller clamping mechanisms 5.

[0022] Please see Figures 1-2 In this embodiment, the clamping mechanism 5 includes a first clamping arm 12 and a second clamping arm 13. A movable sleeve 16 is provided between the first clamping arm 12 and the second clamping arm 13, and the first clamping arm 12 and the second clamping arm 13 are movably connected through the movable sleeve 16. The rear end of the first clamping arm 12 extends into the interior of the rotating groove 17. Rotating shafts are provided on both sides of the rear end of the first clamping arm 12. The end of the rotating shaft away from the first clamping arm 12 extends into the interior of the rotating hole 18. The outer ends of the first clamping arm 12 and the second clamping arm 13 are provided with reinforcing ribs 14. A limiting block 15 is provided at the end of the second clamping arm 13 away from the first clamping arm 12. The first clamping arm 12, the second clamping arm 13, and the limiting block 15 are connected through the limiting block 15. When the first clamp arm 12 is installed in the rotating groove 17 on the front side of the puller body 4 via a rotating shaft, the rear end of the first clamp arm 12 is mounted on the rotating shaft 18. The rotating shaft can rotate in the rotating hole 18, so that the angle of the first clamp arm 12 can be flexibly adjusted. The first clamp arm 12 and the second clamp arm 13 are movably connected by a movable sleeve 16, which makes it easy to adjust the size of the jaws according to the size of the wheel. The operator opens the first clamp arm 12 and the second clamp arm 13 to cover the wheel to be pulled out. The limiting block 15 on the second clamp arm 13 is used to hold the edge of the wheel. The battery pack provides power to the pulling clamp mechanism 5, so that the first clamp arm 12 and the second clamp arm 13 cooperate with the movable sleeve 16 via the rotating shaft to pull the wheel.

[0023] Please see Figures 2-3 In this embodiment, four sets of rotating grooves 17 are provided around the front end of the puller body 4. Rotating holes 18 are provided on both sides of the four sets of rotating grooves 17. A push hole 19 is provided through the center of the puller body 4. The top-piling mechanism 6 includes a push shaft plate 21, which is located at the front end center of the puller body 4. A hydraulic push rod 20 is provided at the rear end of the top shaft plate. One end of the hydraulic push rod 20 is connected to the top shaft plate, and the other end of the hydraulic push rod 20 extends through the push hole 19 to the rear end of the puller body 4. A hydraulic cylinder 22 is provided at the other end of the hydraulic push rod 20. By combining the hydraulic push rod 20 with the top shaft plate, the hydraulic cylinder 22 pushes the hydraulic push rod 20 forward while the puller mechanism 5 pulls out the wheel. The hydraulic push rod 20 drives the push shaft plate 21 to apply a thrust in the direction of the motor shaft. At the same time, the four sets of puller mechanisms 5 are subjected to reverse pressure, firmly pulling the wheel. With the cooperation of the top-piling mechanism 6 and the four sets of puller mechanisms 5, the wheel is pulled out from the motor shaft.

[0024] Please see Figures 3-4 In this embodiment, a battery pack corresponding to the clamping mechanism 5 is provided at the lower center of the lifting plate. A display panel 7 is provided on one edge of the lifting plate surface, and a control box 8 is provided on one side of the display panel 7. The control box 8 integrates a wireless module (wireless module model is ESP8266). The control box 8, the display panel 7 and the battery pack are electrically connected. Through the combination of the battery pack, the display panel 7 and the control box 8, the battery pack can provide power to the entire device, and the corresponding parameters are displayed on the display panel 7. At the same time, the operator can connect an external remote control through the wireless module integrated in the control box 8 to control the operation. Personnel can remotely control the device from a safe position or operate it through the control box 8. Four sets of lifting shafts 9 are provided between the lifting plate and the carriage 1. The bottom of the carriage 1 is provided with telescopic cylinders 11 corresponding to the four sets of lifting shafts 9. Universal wheels 10 are provided at the bottom corners of the carriage 1. A push handle 3 is provided at the rear end of the carriage 1. By combining the lifting shafts 9 with the telescopic cylinders 11, the telescopic cylinders 11 can push the lifting shafts 9 to lift and lower, thereby adjusting the height of the puller body 4. By combining the push handle 3 with the universal wheels 10, the staff can easily move the puller body 4 to a suitable position.

[0025] When working, the staff pushes the platform 1 and uses the casters 10 at the bottom of the platform 1 to move the electric hydraulic wheel puller to the equipment that needs to pull the wheel. After reaching the appropriate position, the staff activates the telescopic cylinder 11 at the bottom of the platform 1 that corresponds to the lifting shaft 9. The telescopic cylinder 11 pushes the lifting shaft 9, thereby driving the lifting support plate 2 to rise or fall, adjusting the wheel puller body 4 to match the height of the wheel to be pulled.

[0026] When pulling out the wheel, the operator opens the first clamp arm 12 and the second clamp arm 13 to cover the wheel to be pulled out. The limiting block 15 on the second clamp arm 13 is used to hold the edge of the wheel. The battery pack provides power to the pulling clamp mechanism 5, so that the first clamp arm 12 and the second clamp arm 13 cooperate with the movable sleeve 16 through the rotating shaft to pull out the wheel.

[0027] As the pulling mechanism 5 pulls out the rotating wheel, the hydraulic cylinder 22 pushes the hydraulic push rod 20 forward. The hydraulic push rod 20 drives the push shaft disc 21 to apply a thrust in the direction of the motor shaft. At the same time, the four sets of pulling mechanisms 5 are subjected to reverse pressure, firmly holding the rotating wheel. With the cooperation of the top pile mechanism 6 and the four sets of pulling mechanisms 5, the rotating wheel is pulled out from the motor shaft.

[0028] Through the above steps, this application combines the wheel puller body 4, the carriage 1, the lifting support plate 2, the pulling clamp mechanism 5, and the top-pile mechanism 6. During operation, the operator first moves the wheel puller body 4 to a suitable position using the carriage 1, then adjusts the height of the wheel puller body 4 to the appropriate position using the lifting support plate 2. Next, the four sets of pulling clamp mechanisms 5 fix the wheel to be pulled out. Then, the top-pile mechanism 6 supports the motor shaft, and simultaneously, the four sets of pulling clamp mechanisms 5 and the top-pile mechanism 6 exert opposing forces to pull the wheel out of the motor shaft. The combination of the pulling clamp mechanism 5 and the top-pile mechanism 6 achieves mechanized wheel pulling, reducing manpower requirements; typically, only one person is needed to operate it, greatly improving wheel pulling efficiency.
