[0034] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0035] See Figure 1-4 The utility model discloses an electric cylinder lifting auxiliary device 1, which includes a bracket 11, a traction member 13, a rotating member 14, and a supporting platform 15. The bracket 11 is installed above the supporting platform 15, and the traction member 13 and the rotating member 14 are installed on the bracket 11. An electric cylinder test position is provided on the supporting platform 15, and the electric cylinder is placed on the electric cylinder test position for testing.

[0036] The bracket 11 comprises two parallel horizontal frames 111 and a vertical frame 112, which are arranged perpendicular to each other. The horizontal frames 111 are equipped with rotating members 14, and the pulling member 13 is connected to the rotating members 14. The ends of the pulling member 13 are respectively connected to the rotating members 14 on the two horizontal frames 111. Specifically, the electric cylinder test position is located between the two horizontal frames. The rotating members 14 are fixedly mounted at both ends of the horizontal frames 111, and the ends of the pulling member 13 are respectively mounted on the rotating members 14. The electric cylinder test position is located in the middle of the pulling member 13. When the pulling member 13 is pulled at both ends, the pulling member 13 between the horizontal frames shortens and the middle portion rises, thereby driving the electric cylinder to be tested to rise.

[0037] Specifically, the auxiliary device pulls the electric cylinder to be tested to the position of the test cylinder on the supporting platform 15 through the traction member 13. The middle part of the traction member 13 is connected to the electric cylinder to be tested, and the traction member 13 drives the rotating member 14 to rotate. One end of the traction member 13 is fixed. By pulling the other end of the traction member 13, the middle part of the traction member 13 is raised, thereby pulling up the electric cylinder to be tested, making it easier to lift the electric cylinder to be tested onto the supporting platform 15 and reducing the difficulty of manual handling.

[0038] Furthermore, the combination of the traction member 13 and the rotating member 14 forms a labor-saving device, which enables the operator to more conveniently lift the heavier electric cylinder to be tested.

[0039] In one embodiment, the auxiliary device includes a suspension member connected to the traction member 13. Specifically, the suspension member can be a suspension structure such as a hook, and the electric cylinder to be tested can be lifted by the suspension member. The electric cylinder to be tested can be pre-tightened, such as by bundling, to stabilize the contact point of the electric cylinder to be tested during lifting to prevent it from falling.

[0040] The auxiliary device includes an adjustment assembly 12 connected to the horizontal frame 111 and arranged perpendicular to the vertical frame 112. The rotating member 14 is mounted on the adjustment assembly 12. Specifically, the adjustment assembly 12 can drive the rotating member 14 to move, so that the electric cylinder to be tested can be moved to the corresponding electric cylinder test position under the drive of the adjustment assembly 12.

[0041] The adjusting assembly 12 includes a guide rail 121, a slider 122, a movable plate 123, a fixing member 124, a driving motor 125, a screw rod 126, a movable block 127 and a fixed block 128. The slider 122 is connected to the guide rail 121, and the guide rail 121 is mounted on the transverse frame 111. The guide rail 121 is arranged parallel to the transverse frame 111. The two ends of the movable plate 123 are respectively connected to the sliders 122 on the two transverse frames. The rotating member 14 is respectively mounted on the two ends of the movable plate 123, the fixing member 124 and the slider 122 are respectively mounted on two opposite surfaces of the movable plate 123, the rotating member 14 is connected to the fixing member 124, the movable block 127 is fixedly arranged in the middle of the movable plate 123, the screw rod 126 is connected to the movable block 127, and the fixed block 128 is mounted on the vertical frame 112. The fixed block 128 has a rotating hole, and the screw rod 126 is arranged through the rotating hole.

[0042] Specifically, the driving motor 125 drives the screw rod 126 to rotate, and the moving block 127 on the moving plate 123 is provided with an opening, and the screw rod 126 passes through the opening, and the inner wall of the opening is provided with a threaded structure that matches the surface of the screw rod 126. Through the cooperation between the moving block 127 and the screw rod 126, when the screw rod 126 rotates, the moving block 127 is driven to move along the screw rod 126. The fixed block 128 provided on the vertical frame 112 is fixedly provided, and the screw rod 126 passes through the rotating hole on the fixed block 128. The inner diameter of the rotating hole of the fixed block 128 is larger than the outer diameter of the screw rod 126. The fixed block 128 is used to fix and limit the screw rod 126 to prevent the screw rod 126 from driving the fixed block 128 to move. The guide rail 121 is installed on the horizontal frame, and the slider 122 It is slidably connected to the guide rail 121, and the guide rail 121 is arranged parallel to the screw rod 126. The slider 122 can move along the guide rail 121, so that the movable plate 123 installed on the slider 122 moves along the guide rail 121. The fixed part 124 is the installation mechanism of the rotating part 14. The rotating part 14 is provided with a rotating shaft, and both ends of the rotating shaft are installed on the fixed part 124. The rotating part 14 can rotate around the rotating shaft. The traction part 13 is in contact with the surface of the rotating part 14, and the traction part 13 can drive the rotating part 14 to rotate. The rotating part 14 can divide the traction part 13 into two parts, so that the gravity exerted on the electric cylinder to be tested is decomposed into forces in two directions at the two ends of the movable plate 123 where the rotating parts 14 are located, so that the force is uniform and the force exerted on one end of the traction force is reduced.

[0043] When lifting the electric cylinder under test, the middle portion of the traction member 13 is connected to the cylinder under test and pulls the cylinder. One end of the traction member 13 is fixed, while the other end applies tension, pulling the traction member 13 toward one end. This shortens the length of the traction member 13 between the two ends of the movable plate 123, thereby raising the middle portion of the traction member 13. Furthermore, the traction member 13 can be stretched from both ends, shortening the distance between the two ends of the movable plate 123 and raising the middle portion of the traction member 13, thereby lifting the electric cylinder under test. Applying force from both ends allows the operator at each end to apply less force than would be required when directly lifting the cylinder under test, saving operator effort.

[0044] In one embodiment, the traction member 13 is a pull rope, and the rotating member 14 is a fixed pulley, with both ends of the pull rope contacting the fixed pulley. Specifically, the fixed pulley's rotating shaft is connected to the fixed member 124, and the fixed pulley rotates around it. The pull rope wraps around the surface of the fixed pulley, driving the fixed pulley to rotate. The middle of the pull rope is connected to the electric cylinder under test. By applying force at both ends or one end of the traction member 13, the electric cylinder under test is pulled up.

[0045] As an embodiment, the traction member 13 is a chain, and the rotating member 14 is a sprocket. The chain is meshed with the sprocket. Specifically, the meshing of the chain and the sprocket reduces the relative movement between the traction member 13 and the rotating member 14. Force can be applied at both ends of the chain, shortening the chain length between the two ends of the movable plate 123, thereby driving the electric cylinder to be tested to rise. Furthermore, the chain can be provided with automated equipment at either or both ends to apply force, thereby increasing the degree of automation of the device. Furthermore, the installation between the chain and the suspension member is more convenient, and the provision of a corresponding meshing mechanism makes the installation between the two more stable.
