DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Example 1: Reference Figure 1-Figure 2 A hoisting device for preventing a module from sinking during hoisting comprises: a crossbeam 1, a hoisting assembly 2, a bevel gear 3, a double screw 4 and a clamp arm 5. A longitudinal beam is installed at the bottom of the crossbeam 1, a slide groove is opened on the bottom surface of the longitudinal beam, a motor is installed at the bottom of the crossbeam 1, a bevel gear 3 is installed at the output end of the motor, the bevel gear 3 is meshed and connected with the second bevel gear, the second bevel gear is installed on the double screw 4, the end of the double screw 4 is rotatably connected with the inner wall of the slide groove, the double screw 4 is threadedly connected with two clamp arms 5, the top of the clamp arm 5 is slidably matched with the slide groove, and the crossbeam 1 is equipped with a hoisting assembly 2.

[0028] The principle of the above scheme is:

[0029] After the hoisting assembly 2 hoists both sides of the module, the motor is started, and the output end of the motor drives the bevel gear 3 to rotate forward, and the bevel gear 3 drives the bevel gear 2 and the double screw 4 meshing with it to rotate in the opposite direction, and the double screw 4 drives the two clamping arms 5 to move closer to each other to clamp the end face of the module.

[0030] The beneficial effects of the above scheme are:

[0031] The double screw 4 is arranged to drive the two clamping arms 5 to approach each other in the slide slot to hold the module tightly, thereby preventing the battery cell in the middle of the module from sinking under the action of gravity during transportation;

[0032] At the same time, the double screw 4 is threadedly connected to the two clamping arms 5. When the relative positions of the two clamping arms 5 need to be adjusted, the synchronization and accuracy of the movement of the clamping arms 5 are improved, ensuring that the two clamping arms 5 can simultaneously clamp the two end faces of the module.

[0033] Example 2: Reference Figure 2 The clamp arm 5 is provided with a rubber 6, and the end faces of the two rubbers 6 are arranged opposite to each other.

[0034] The principles and beneficial effects of the above scheme are:

[0035] Installing the high-strength glue 6 on the clamp arm 5 can increase the friction force of the clamp arm 5 when it is clamping the module.

[0036] A plurality of protrusions are arranged on the end surface of the urethane foam 6.

[0037] The principles and beneficial effects of the above scheme are:

[0038] There are multiple bumps on the rubber 6, and the bumps and the rubber 6 are made of the same rubber material. A gap can be generated between the bumps and the rubber 6 between the end faces of the module to prevent the rubber 6 from being adsorbed on the end faces of the module due to the effect of air pressure after the end faces of the module are tightly hugged.

[0039] Example 3: Reference Figure 1 , Figure 2 and Figure 3 The hoisting assembly 2 includes: a double screw 2 7, a movable plate 8, a hoisting mechanism 9 and a driving mechanism 10. The top surface of the cross beam 1 is rotatably connected with a double screw 2 7, and two movable plates 8 are threadedly connected to the double screw 2 7. The movable plate 8 is slidably matched with the slide groove 2 of the cross beam 1. The bottom end of the movable plate 8 is connected with the hoisting mechanism 9, and the double screw 2 7 is connected to the driving mechanism 10.

[0040] The principle of the above scheme is:

[0041] Before holding the module tightly, start the driving mechanism 10, which drives the twin screws 7 to rotate forward, and the two moving plates 8 drive a hoisting mechanism 9 to approach each other and hoist the module;

[0042] When the module needs to be released, the driving mechanism 10 is started again, and the driving mechanism 10 drives the double screw 2 7 to reverse, and the two moving plates 8 respectively drive a hoisting mechanism 9 to move away from each other and end the hoisting of the module.

[0043] The beneficial effects of the above scheme are:

[0044] The double screw 7 is arranged to drive the two movable plates 8 to move closer or further away to assist in holding the sides of the ink, and the two lifting mechanisms 9 cooperate with each other to lift the bottom end of the module or the lifting station on the module, and the movable plates 8 and the lifting mechanisms 9 cooperate with each other to improve the stability of the module during lifting.

[0045] Example 4: Reference Figure 3 The driving mechanism 10 includes: a motor 11, a worm 12 and a worm wheel 13. The twin screw 7 is provided with a worm wheel 13, which is meshed with the worm 12. The worm 12 is rotatably mounted on the top surface of the beam 1. The end of the worm 12 is connected to the output end of the motor 11, and the motor 11 is mounted on the top surface of the beam 1.

[0046] The principle of the above scheme is:

[0047] The output end of the second motor 11 drives the worm 12 to rotate forward, the worm 12 drives the worm wheel 13 meshing with it to rotate forward, and the worm wheel 13 drives the twin screw 2 7 to rotate forward; the output end of the second motor 11 drives the worm 12 to rotate reversely, the worm 12 drives the worm wheel 13 meshing with it to rotate reversely, and the worm wheel 13 drives the twin screw 2 7 to rotate reversely;

[0048] The beneficial effects of the above scheme are:

[0049] A worm 12 is provided to drive a worm wheel 13 meshing with the worm wheel 12 to rotate, and the worm wheel 13 rotates synchronously with the double screw 2 7. When the worm wheel 13 stops rotating, the worm wheel 13 and the double screw 2 7 are locked to ensure that the movable plate 8 and the lifting mechanism 9 will not move during lifting, thereby ensuring safety during lifting.

[0050] Example 5: Reference Figure 2 , Figure 4 and Figure 5 The lifting mechanism 9 includes: a movable plate 14, a plug rod 15, a sleeve 16 and an adjustment mechanism 17. The movable plate 8 is connected to the plug rod 15 at the bottom, and the bottom end of the plug rod 15 is slidably connected to the top end of the sleeve 16. The bottom end of the sleeve 16 is installed on the movable plate 14, and an adjustment mechanism 17 is provided between the movable plate 14 and the movable plate 8.

[0051] A hook 18 is mounted on one side of the bottom surface of the second movable plate 14 , and the end of the hook 18 is arranged toward the middle of the beam 1 .

[0052] The adjusting mechanism 17 includes: a rotating shaft 19, a bevel gear three 20, a bevel gear four 21 and a screw 22. The end face of the movable plate 8 away from the motor two 11 is rotatably connected with the rotating shaft 19. A hand wheel is installed at the end of the rotating shaft 19, and a bevel gear three 20 is installed at the other end of the rotating shaft 19. The bevel gear three 20 is meshed and connected with the bevel gear four 21. The bevel gear four 21 is installed on the screw 22, and the screw 22 is threadedly connected with the screw block on the side of the movable plate two 14.

[0053] The principle of the above scheme is:

[0054] When it is necessary to hoist modules of different heights or with hoisting stations of different heights, the hand wheel is turned counterclockwise, and the rotation of the hand wheel drives the rotating shaft 19 to rotate, and the bevel gear 3 20 on the rotating shaft 19 drives the bevel gear 4 21 meshing with it to rotate, and the bevel gear 4 21 drives the screw rod 22 to rotate clockwise, and the screw block threadedly connected with the screw rod 22 drives the moving plate 2 14 to descend, and the hand wheel is turned clockwise to make the moving plate 2 14 rise;

[0055] When the movable plate 14 rises or falls, the sleeve 16 rises or falls relative to the insertion rod 15 and guides the movement of the movable plate 14, thereby causing the hook 18 installed on the bottom surface of the movable plate 14 to rise or fall synchronously.

[0056] The beneficial effects of the above scheme are:

[0057] The adjustment of the position of the hook 18 makes it easier for the device to hoist the bottom of modules of different heights; when a hoisting station is provided on the module, the module can be hoisted after the position of the hook 18 is finally adjusted by turning the hand wheel according to its actual height, thereby improving the practicability and adaptability of the device.

[0058] Example 6: Reference Figure 5-Figure 6 , and also includes: a positioning mechanism 23, the positioning mechanism 23 includes: a ratchet 24, a pawl 25 and a torsion spring 26, the ratchet 24 is mounted on the rotating shaft 19, the ratchet 24 is meshed and connected with the pawl 25, the pawl 25 is installed on the rotating shaft 2, the rotating shaft 2 is rotatably matched with the vertical plate on the movable plate 8, a torsion spring 26 is installed between the vertical plate and the pawl 25, and a handle is installed on the rotating shaft 2.

[0059] The principle of the above scheme is:

[0060] Turn the handle counterclockwise, the handle drives the second shaft, pawl 25 and torsion spring 26 to rotate, the pawl 25 disengages from the meshing connection with the ratchet 24, and the hand wheel can be rotated; loosen the handle, the torsion spring 26 drives the second shaft and pawl 25 to reset, the pawl 25 fixes the ratchet 24 to prevent the shaft 19 from rotating.

[0061] The beneficial effects of the above scheme are:

[0062] The ratchet 24 and the pawl 25 are meshed and connected to prevent the screw 22 from rotating during hoisting, thereby further improving the stability and safety of the module during hoisting;

[0063] The pawl 25 is arranged to lock the ratchet wheel 24 in the counterclockwise direction. To adjust the height of the hook 18 downward, the hand wheel needs to be turned counterclockwise to ensure that the positioning mechanism 23 can lock the rotating shaft 19 when the module is hoisted.

[0064] Example 7: Reference Figure 4 Two lifting rings 27 are installed at the top of the crossbeam 1.

[0065] The principles and beneficial effects of the above scheme are:

[0066] A lifting ring 27 is provided on the cross beam 1, and a steel wire rope or a steel hook can be inserted into the lifting ring 27, so that the device can be moved by a lifting device after the device is tightly clamped to the module lifting machine.
