Figure 7 This is a schematic diagram of the assembly structure of the lifting self-locking device 100 with the connecting seat 30 in the second position provided in this application embodiment.
[0027] Please see Figure 1 This application provides a lifting self-locking device 100 and a lifting device 1000 including the lifting self-locking device 100. The lifting device 1000 also includes an oven 200, which is connected to the lifting self-locking device 100. The lifting self-locking device 100 can drive the oven 200 to move up and down, so that the staff can complete the relevant inspection work on the oven 200.
[0028] Please see Figures 1 to 4The lifting self-locking device 100 includes a bracket 10, a drive component 20, a connecting seat 30, and a self-locking assembly 40. The bracket 10 can be fixed to the ground. The drive component 20 is located on one side of the bracket 10 and can be fixed to the ground or fixedly connected to the bracket 10. The connecting seat 30 is connected to the drive component 20, which can drive the connecting seat 30 to move between a first position and a second position, with the first position above the second position. The connecting seat 30 is fixedly connected to the oven 200. When the connecting seat 30 is in the first position, operators can perform inspection operations. The self-locking assembly 40 is disposed on the bracket 10 and the connecting seat 30. When the connecting seat 30 is in the first position, the self-locking assembly 40 can self-lock, thereby preventing the connecting seat 30 from moving downwards and reducing safety hazards.
[0029] Please refer to the following: Figures 5 to 7 In some embodiments, the self-locking component 40 includes a first hook 41 and a second hook 42, the first hook 41 being connected to the bracket 10 and the second hook 42 being connected to the connecting seat 30.
[0030] When the connecting seat 30 is in the first position, the first hook 41 and the second hook 42 cooperate to prevent the connecting seat 30 from moving downward; the self-locking component 40 is configured such that at least one of the first hook 41 or the second hook 42 can rotate to release the cooperation between the first hook 41 and the second hook 42, so that the connecting seat 30 can move to the second position.
[0031] The self-locking mechanism achieved by the cooperation of the first hook 41 and the second hook 42 ensures that the connecting seat 30 is stably positioned in the first position, thereby improving safety and reducing potential hazards. By enabling at least one of the first hook 41 and the second hook 42 to rotate, allowing them to engage, the connecting seat 30 can move to the second position under its own weight and the weight of the oven 200. This movement of the connecting seat 30 to the second position is simple and convenient.
[0032] In some embodiments, the first hook 41 is provided with a first guide surface 4121, and the second hook 42 is provided with a second guide surface 4221. The first guide surface 4121 and the second guide surface 4221 cooperate, so that when the connecting seat 30 moves towards the first position, the first guide surface 4121 will contact the second guide surface 4221, thereby causing the rotatable structures in the first hook 41 and the second hook 42 to rotate, so that the connecting seat 30 can move smoothly to the first position. After the connecting seat 30 moves to the first position, the rotated structures in the first hook 41 and the second hook 42 can return to their original positions, so that the first hook 41 and the second hook 42 cooperate to achieve self-locking.
[0033] In some embodiments, the first hook 41 is rotatably connected to the bracket 10, and the bracket 10 is configured to move to a mating position under gravity. The mating position of the first hook 41 can be understood as the position where the first hook 41 can engage with the second hook 42 when the connecting seat 30 is in the first position. Optionally, the second hook 42 is fixedly connected to the connecting seat 30.
[0034] By setting the first hook 41 to be rotatably connected to the bracket 10, the first hook 41 can be moved to the mating position under the action of gravity. After the connecting seat 30 moves to the first position, the first hook 41 will automatically engage with the second hook 42, thereby achieving self-locking. The self-locking method is simple and quick.
[0035] It should be noted that the self-locking method is not limited to the first hook 41 being able to rotate while the second hook 42 remains fixed.
[0036] In some embodiments, the first hook 41 is fixedly connected to the bracket 10, the second hook 42 is rotatably connected to the connecting seat 30, and a torsion spring is provided at the connection between the second hook 42 and the connecting seat 30 so that when the connecting seat 30 moves to the first position, the first hook 41 contacts the second hook 42, and after the second hook 42 rotates, the second hook 42 can automatically reset.
[0037] When the first hook 41 is rotatably connected to the bracket 10 and the second hook 42 is fixedly connected to the connecting seat 30, the first hook 41 may include a connecting arm 411 and a first hook 412. One end of the connecting arm 411 is rotatably connected to the bracket 10, and the other end of the connecting arm 411 is connected to the first hook 412, which is bent upward. A first guide surface 4121 is provided at the end of the first hook 412 opposite to the connecting arm 411. Correspondingly, the second hook 42 is bent downward at the point where it engages with the first hook 412, so that the first hook 412 can engage with the second hook 42.
[0038] In some embodiments, the second hook 42 includes a vertical plate 421 and a second hook 42. The vertical plate 421 is fixedly connected to the connecting seat 30, and the second hook 42 is fixedly connected to the vertical plate 421, and the second hook 42 is bent downward. Optionally, the second vertical plate 421 and the connecting seat 30 can be fixedly connected by welding, bolting, or other methods.
[0039] In some embodiments, there are two first hooks 41 and two second hooks 42. The two first hooks 41 are disposed on opposite sides of the bracket 10, and the two second hooks 42 are disposed at intervals and correspond to the positions of the first hooks 41.
[0040] By setting two first hooks 41 and two second hooks 42 to cooperate, stability can be improved.
[0041] In some embodiments, the self-locking assembly 40 further includes a vertical pole 43 and a hanging rope 44. The vertical pole 43 is disposed on the connecting seat 30 and located on one side of the bracket 10, and the vertical pole 43 is vertically arranged. The hanging rope 44 is connected to the first hook 41.
[0042] When the connecting seat 30 is in the first position, the hanging rope 44 can be hooked onto the upright 43 to cooperate with the upright 43. Thus, by pulling the hanging rope 44, the first hook 41 can rotate and separate from the second hook 42. This releases the self-locking between the first hook 41 and the second hook 42, allowing the connecting seat 30 to move to the second position.
[0043] When the connecting seat 30 moves to the second position, the connecting seat 30 drives the upright 43 to move, so that the hanging rope 44 can separate from the upright 43. Then, under the action of gravity, the first hook 41 can rotate back to the mating position. When the connecting seat 30 moves to the first position again, it can achieve self-locking again.
[0044] By setting the hanging rope 44 to hang on the upright 43 to release the self-locking of the first hook 41 and the second hook 42, it is possible to cleverly allow the first hook 41 to move to the matching position under the action of gravity when the connecting seat 30 moves to the second position. The whole process is simple and convenient to operate. By pulling the hanging rope 44 instead of the staff directly rotating the first hook 41, safety can be further improved.
[0045] In some embodiments, one end of the hanging rope 44 is connected to a first hook 41 and the other end is connected to another first hook 41, so that the hanging rope 44 can drive the two first hooks 41 to rotate at one time, and can be directly hung on the upright 43, and can ensure that when the connecting seat 30 moves to the second position, the hanging rope 44 can be detached from the upright 43.
[0046] In some embodiments, the connecting seat 30 is provided with a through groove 311, which extends vertically through the upper and lower sides of the connecting seat 30. The bracket 10 passes through the through groove 311 so that the first hook 41 and the second hook 42 can be adjacent to each other, which helps to improve the tightness of the overall structure. Optionally, the bracket 10 and the through groove 311 are fitted with a clearance to reduce the contact between the bracket 10 and the connecting seat 30 and to reduce the resistance when the connecting seat 30 is raised or lowered.
[0047] In some embodiments, the connecting seat 30 includes a flat plate 31 and a vertical plate 312. The flat plate 31 is horizontally arranged, and a through groove 311 is located on the flat plate 31 and extends through the upper and lower sides of the flat plate 31. The vertical plate 312 is disposed on one side of the flat plate 31, and the side of the vertical plate 312 away from the flat plate 31 is fixedly connected to the oven 200. Optionally, the vertical plate 312 is fixedly connected to the oven 200 by bolts.
[0048] In some embodiments, the second hook 42 connects the flat plate 31 and the vertical plate 312. Specifically, the bottom of the vertical plate 421 of the second hook 42 is fixedly connected to the flat plate 31, and one side of the vertical plate 421 is fixedly connected to the vertical plate 312, so that the vertical plate 421 can act as a reinforcing rib to increase the stability between the flat plate 31 and the vertical plate 312.
[0049] In some embodiments, the support 10 is vertically arranged and generally rod-shaped, and the cross-section of the support 10 is generally rectangular.
[0050] In some embodiments, the lifting self-locking device 100 further includes a fixing plate 50, which is fixed to the ground support 10 and the driving component 20 are both fixed to the fixing plate 50 by bolts.
[0051] In some embodiments, the drive element 20 is a cylinder, which can easily push the connecting seat 30 to move up and down in the vertical direction.
[0052] In summary, the embodiments of this application provide a lifting self-locking device 100 and a lifting device 1000. When the connecting seat 30 moves to the first position, the first hook 41 and the second hook 42 can engage to achieve self-locking, thereby maintaining the stability of the connecting seat 30. This effectively reduces the risk of the connecting seat 30 sliding to the second position due to workers forgetting to insert the latch or malfunction of the electric or pneumatic control device. It effectively reduces safety hazards and improves equipment safety. In addition, by setting the hanging rope 44 to engage with the upright 43, when the hanging rope 44 is hung on the upright 43, the first hook 41 and the second hook 42 can separate to release the self-locking. After the hanging rope 44 separates from the upright 43, the first hook 41 can move back to the engaging position under the action of gravity, making the operation simple and convenient.
