Description

Technical Field

[0001] This utility model relates to the technical field of lifting equipment for production lines, specifically a transfer lifting device. Background Technology

[0002] The transfer system is a mechanized conveying equipment suitable for automobile processing and production. Its function is to transfer production parts between different production lines in the automobile final assembly workshop, and it is also suitable for mass production of vehicles.

[0003] Specifically, the transfer system mainly includes a transfer hoist. In the actual production process of the car body production line, after the interior AGV is mounted on the car body and the interior line is processed, the transfer hoist can complete the conversion of the car body from the interior AGV to the chassis line hoist at the interior-chassis transfer station. After the chassis line hoist is mounted on the car body and the chassis line is processed, the transfer hoist can complete the conversion of the car body from the chassis line hoist to the exterior AGV at the chassis-exterior transfer station, thus adapting to multiple production lines producing simultaneously.

[0004] In existing technologies, adapters are often only compatible with one type of vehicle model. When a new vehicle model is introduced into the production line, the existing adapters may not be able to accommodate it, requiring the adapter structure to be modified. This increases production costs and capital investment, and also affects the production progress of the entire production line. Utility Model Content

[0025] Please see Figure 1-5A transfer lifting device includes a lifting device body 1 and a lifting device frame 5 mounted on the lifting device body 1. The lifting device body 1 has four sliding cavities 6, and sliding rods 8 are slidably arranged within each cavity 6. The two sliding rods 8 with the smallest spacing are fitted with the same side support plate 2. A stop block 9 is provided at the end of each sliding rod 8 away from the side support plate 2. A through hole 7, which communicates with the outside and is adapted to the diameter of the sliding rod 8, is provided on one inner wall of each sliding cavity 6. A transmission cavity 10 is provided within the lifting device body 1, with the center of the transmission cavity 10... A transmission gear 11 is rotatably mounted on the device. Two sliding blocks 12 are slidably arranged in the transmission cavity 10. The two sliding blocks 12 are respectively welded to the two side support plates 2. A rack 13 is protruding on the sliding block 12. The rack 13 has a tooth groove 14 that meshes with the transmission gear 11. A self-locking mechanism for locking the transmission gear 11 is provided on the main body 1 of the lifting device. Multiple hollows 3 are provided on both the main body 1 of the lifting device and the side support plates 2. Multiple protrusions 4 for welding to the lifting frame 5 are protruding on the main body 1 of the lifting device.

[0026] The transmission mechanism, consisting of the main body 1, side support plates 2, and transmission gear 11, allows for adjustments to the size of the main body 1 when necessary. Rotating the transmission gear 11 moves the two racks 13 closer together or further apart. This, in turn, the sliding blocks 12 connected to the racks 13 move the two side support plates 2 closer together or further apart, thus adjusting the size of the lifting device. The sliding rod 8 guides the movement of the side support plates 2, and the stop block 9 at the end of the sliding rod 8 restricts the range of movement of the side support plates 2, preventing them from detaching from the connection with the main body 1.

[0027] Specifically, in this embodiment, the transmission gear 11 is provided with a connecting shaft 15 that passes through the transmission cavity 10 and extends to the outside. A handwheel 22 is installed at one end of the connecting shaft 15 that extends to the outside.

[0028] The handwheel 22 allows for easy rotation of the transmission gear 11, thereby adjusting the distance between the two side support plates 2 and the main body 1 of the lifting device.

[0029] Specifically, in this embodiment, sliding holes that communicate with the outside and are adapted to the size of the sliding block 12 are provided on both sides of the inner wall of the transmission cavity 10.

[0030] The sliding hole allows the sliding block 12 to slide within it.

[0031] Specifically, in this embodiment, the self-locking mechanism includes a reset slide groove 17 opened on the lifting device body 1, a reset slider 18 slidably arranged in the reset slide groove 17, a self-locking block 19 protruding from one end of the reset slider 18, and a plurality of self-locking grooves 16 adapted to the self-locking block 19 are arranged at intervals along the circumference on the connecting shaft 15.

[0032] With the self-locking block 19 and the self-locking groove 16, when the position of the side support plate 2 needs to be adjusted, the reset slider 18 can be moved away from the connecting shaft 15. At this time, the self-locking block 19 moves away from the self-locking groove 16, releasing the lock on the connecting shaft 15. At this time, the transmission gear 11 can be rotated by turning the handwheel 22. Conversely, the connecting shaft 15 can be locked to prevent the distance between the side support plate 2 and the lifting device body 1 from changing during use.

[0033] Specifically, in this embodiment, a guide rod 21 is provided in the reset slide groove 17, and a guide hole adapted to the guide rod 21 is provided on the reset slider 18. Through the setting of the guide rod 21 and the guide hole, the moving direction of the reset slider 18 can be guided, and the moving process of the reset slider 18 can be made more stable.

[0034] Specifically, in this embodiment, a return spring 20 is sleeved on the guide rod 21. One end of the return spring 20 abuts against the inner wall of the return groove 17, and the other end of the return spring 20 abuts against the return slider 18. By setting the return spring 20, the return slider 18 can always be pressed against the inner wall of the return groove 17 under normal conditions, thereby enabling the self-locking block 19 to always remain pressed against the self-locking groove 16 without manual operation, thus ensuring the self-locking stability of the connecting shaft 15. When the return slider 18 is moved away from the connecting shaft 15, the return slider 18 can squeeze the return spring 20 to produce deformation. When the return slider 18 is released, the elastic potential energy of the return spring 20 can make the return slider 18 automatically reset.

[0035] Specifically, in this embodiment, the reset slider 18 is provided with an adjustment block 23 extending to the outside, which can facilitate the movement of the reset slider 18 by adjusting the adjustment block 23.

[0036] It should be noted that the selection of transmission gears, transmission sliders, return springs, and other standard parts, as well as the assembly process between these standard parts, are common knowledge in this field and will not be elaborated upon here.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
