Technical Field

[0001] The utility model relates to the technical field of hoists, and particularly relates to a hoist provided with a locking mechanism. Background Technique

[0002] A hoist refers to a mechanical device used for lifting and transporting goods. It is a very widely used goods handling tool and is applied in industries such as factories and transportation. Through the hoist, loading and unloading operations are realized, which greatly improves labor efficiency and improves the working conditions of loading and unloading operations.

[0003] For example, the publication number CN214360157U discloses a 1-ton hoist, which includes three support rods. The upper ends of the three support rods are jointly penetrated by a cross bar. A hanging mechanism is sleeved on the cross bar. A hanging chain block is arranged on the hanging mechanism. The hanging chain block is arranged between the three support rods. A first iron chain is installed on the hanging chain block. One end of the first iron chain is fixed with a hook. An adjusting mechanism is arranged on the hook. Two threaded hooks are arranged on the adjusting mechanism. The bottom ends of the three support rods are all fixed with fixing plates. A moving mechanism is jointly arranged at the lower ends of the three fixing plates. The utility model can make the pipeline detection personnel more time-saving and labor-saving through the effective cooperation of components such as the hanging mechanism and the adjusting mechanism, effectively reducing the labor intensity of workers, reducing the original four-person group for pipeline detection to only three people in a group now. At the same time, during the operation, it can be lifted and left at any time, and the personnel do not contact the manhole cover, which is time-saving and labor-saving, and ensures the safety of the personnel.

Specific implementation manner

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-7 , the present invention provides the following technical solutions.

[0034] Embodiment 1: To solve the problem in the prior art that it is inconvenient to fix goods with different placement forms and shapes, therefore, in this embodiment, through the following technical solutions, a hoist with a locking mechanism is provided, which is provided with a bottom plate 1, a fixing frame 3, a connecting plate 14, a fixing clamp 16 and a connecting mechanism 17. The upper end of the bottom plate 1 is fixedly connected with a fixing frame 3. The connecting plates 14 are symmetrically arranged on the left and right sides of the lower end of the fixing cylinder 11 respectively. The lower end of the connecting plate 14 is provided with a fixing clamp 16. Moreover, the connecting mechanism 17 includes an adjusting column 18 penetrating through the lower end of the connecting plate 14 and a fixing bolt 19 for limiting. The adjusting column 18 is fixedly connected to the side of the fixing clamp 16 far from the vertical central axis of the fixing frame 3, and the adjusting column 18 forms a rotating structure at the lower end of the connecting plate 14. Both the adjusting column 18 and the fixing bolt 19 and the connecting plate 14 and the fixing bolt 19 are threadedly connected. As Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, move the hoist to the side of the goods to be transported. According to the placement form and shape of the goods, by flipping the fixing clamp 16, the fixing clamp 16 drives the adjusting column 18 to rotate at the lower end of the connecting plate 14, so as to facilitate the flipping adjustment of the fixing clamp 16. After the adjustment is completed, by rotating the fixing bolt 19 to limit between the adjusting column 18 and the connecting plate 14, the fixing clamp 16 is fixed.

[0035] Embodiment 2: For the existing hoist equipped with a locking mechanism, it is not convenient to stably clamp and position the goods to be transported. Therefore, by providing a fixed long cylinder 11, a second servo motor 12, a lead screw 13, a connecting plate 14 and a support block 15, the right end of the fixed long cylinder 11 is fixedly installed with the second servo motor 12, and the output end of the second servo motor 12 is fixedly connected with the lead screw 13. The second servo motor 12 drives the lead screw 13 to rotate in the fixed long cylinder 11. The left and right ends of the lead screw 13 are both threadedly connected with vertically arranged connecting plates 14. The directions of the threads at the left and right ends of the lead screw 13 are opposite. The front and rear sides of the upper end of the connecting plate 14 are both fixedly connected with support blocks 15, and the support blocks 15 are respectively slidably connected to the front and rear ends of the fixed long cylinder 11, as Figure 1 , Figure 4 and Figure 7 shown. Place the fixed clamping plates 16 on both sides of the goods, start the second servo motor 12 to drive the lead screw 13 to rotate in the fixed long cylinder 11. The lead screw 13 drives the connecting plates 14 to move towards each other at the lower end of the fixed long cylinder 11. At the same time, the connecting plates 14 drive the support blocks 15 to slide with the fixed long cylinder 11, and the connecting plates 14 drive the fixed clamping plates 16 to stably clamp the goods.

[0036] Embodiment 3: For the existing hoist equipped with a locking mechanism, the goods lack a limiting mechanism to lock them in the lifted state, and are prone to slipping or falling. Therefore, by providing moving wheels 2, a fixed frame 3, a support plate 4, a first servo motor 5, a connecting roller 6, a rope 7, a fixing hole 8, an electric telescopic rod 9 and a locking rod 10, moving wheels 2 are installed on the front and rear sides of the lower end of the bottom plate 1. The rope 7 is arranged through the middle of the support plate 4. The middle of the upper end of the fixed frame 3 is fixedly connected with the support plate 4, and the right end of the support plate 4 is fixedly installed with the first servo motor 5. The output end of the first servo motor 5 is fixedly connected with the connecting roller 6, and the first servo motor 5 drives the connecting roller 6 to rotate on the upper end of the support plate 4. The inner side wall of the upper end of the fixed frame 3 is fixedly installed with the electric telescopic rod 9, and the output end of the electric telescopic rod 9 is fixedly connected with the locking rod 10. The electric telescopic rod 9 drives the locking rod 10 to move left and right on the upper end of the fixed frame 3, as Figure 1 , Figure 2 and Figure 3As shown, after the fixed clamping plate 16 finishes clamping the goods, the first servo motor 5 is started to drive the connecting roller 6 to slowly rotate at the upper end of the support plate 4. The rope 7 is wound by the connecting roller 6, and the rope 7 drives the fixed long cylinder 11 to move upward, thereby facilitating the lifting of the goods. When the goods are lifted to an appropriate height, the first servo motor 5 is turned off. At the same time, the electric telescopic rod 9 is started to drive the locking rod 10 to move to the right, so that the locking rod 10 is inserted into the fixing hole 8 at the corresponding position, thereby facilitating the locking and limiting of the connecting roller 6 to prevent it from falling, improving the stability of the goods in the lifted state. Then, the fixed frame 3 is pushed to make the bottom plate 1 drive the moving wheels 2 to move, facilitating the handling of the goods.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
