[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] Please refer to Figure 1-4 , a hoisting device, including a support component and an adjustment component. The support component includes a support roller 1, a top plate 2, a support frame 3 and a lifting ring 4. The support roller 1 and the top plate 2 are arranged concentrically, and the support roller 1 is connected to the center of one end of the top plate 2. The other end of the top plate 2 is provided with a U-shaped support frame 3. The two free ends of the support frame 3 are arranged on the top plate 2. The lifting ring 4 is provided at one end of the support frame 3 away from the top plate 2. The adjustment component includes a motor 5, a left and right threaded screw 6, a driving ring 7, a first hinge seat 8, a second hinge seat 9, a hinge rod 10 and a support plate 11. The support roller 1 is provided with a hollow cavity, and a sliding hole communicating with the hollow cavity is also provided on the surface of the support roller 1. The left and right threaded screw 6 is arranged in the hollow cavity. The output end of the motor 5 penetrates through the support roller 1 and is connected to the left and right threaded screw 6. The driving ring 7 is also arranged in the hollow cavity. The driving ring 7 is provided in two groups and is symmetrically arranged. The driving ring 7 is provided with a first hinge seat 8 slidably connected to the sliding hole. The driving ring 7 is threadedly connected to the left and right threaded screw 6. The support plate 11 is also provided with a second hinge seat 9. The hinge rod 10 is arranged between the corresponding first hinge seat 8 and the second hinge seat 9. The motor 5 is arranged between the two free ends of the support frame 3.
[0022] The support roller 1 and the top plate 2 are arranged concentrically and connected to the center of one end, providing the basic vertical support for the whole device. The U-shaped support frame 3 at the other end of the top plate 2, with its two free ends fixed on the top plate 2, enhances the stability of the overall structure. The lifting ring 4 at one end of the support frame 3 away from the top plate 2 is used to connect with a hoisting device (such as a crane hook, etc.). When the hoisting device applies force, the whole device transmits the force to the support component through the lifting ring 4, and then the support component disperses the force to the adjustment component and the pipe to be hoisted. The motor 5 uses a servo motor 5, which has the characteristics of precise control and fast response. The output end of the motor 5 penetrates through the support roller 1 and is connected to the left and right threaded screw 6 in the hollow cavity. When the motor 5 is started, it drives the left and right threaded screw 6 to rotate. When it rotates, the two symmetrically arranged driving rings 7 will move towards or away from each other along the left and right threaded screw 6 in the hollow cavity according to the rotation direction of the screw. The first hinge seat 8 on the driving ring 7 is slidably connected to the sliding hole on the surface of the support roller 1. The sliding hole cooperates with the first hinge seat 8 to limit the moving direction of the driving ring 7, making it can only move along the axial direction of the screw. When the driving ring 7 moves, it is connected to the second hinge seat 9 on the support plate 11 through the hinge rod 10, driving the support plate 11 to extend or retract. The support plate 11 contacts the inner wall of the pipe and clamps the hoisted pipe. In this embodiment, a storage battery and a controller connected to the motor 5 can also be embedded on the top plate 2 for convenient wireless control.
[0023] The support plate 11 is made of rigid material and can only stably lift materials of a single specification. Therefore, in actual use, a friction pad 12 is further provided at one end of the support plate 11 away from the second hinge seat 9 to facilitate lifting materials of different specifications.
[0024] During actual use, the support plate 11 is arranged in an L shape, and the side wall of the support plate 11 is set at the end away from the motor 5. The side wall of the support plate 11 protrudes from the friction pad 12 to support the pipe and prevent the pipe from slipping off the support plate 11 with the friction pad 12 due to the slippery inner wall.
[0025] During actual use, a guide roller 13 is further provided on the side wall of the support plate 11. The guide roller 13 is arranged at the end away from the second hinged seat 9, and the side wall of the support plate 11 protrudes from the guide roller 13 near the end of the motor 5 so that the equipment can be inserted into the pipe, and at the same time, it is convenient for the equipment to be withdrawn when the pipe is upright.
[0026] In order to explain in detail the possible application scenarios, technical principles, specific solutions that can be implemented, and the purpose and effects of this application, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of this application and are therefore only examples and are not intended to limit the scope of protection of this application.
