[0022] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] See Figure 1 The screw rod auxiliary disassembly device of the present invention comprises a base 1, on which are disposed a plurality of screw rod fixing seats 2 for limiting and fixing the screw rod. The number of screw rod fixing seats 2 can be arranged according to actual needs, and can be arranged according to the diameter length of the screw rod, or can be adaptively adjusted according to the weight of the screw rod, as long as the screw rod can be firmly clamped to prevent it from moving or falling during transportation or movement.

[0024] In the embodiment of the present invention, the disclosed screw auxiliary disassembly device further includes a mobile trolley 3. Specifically, in the embodiment of the present invention, the aforementioned base 1 can be raised and lowered on the mobile trolley 3, thereby enabling the base 1 to be adjusted up and down to adapt to the screw disassembly operation in different states. For the liftable setting, a hydraulic drive component can be connected to the inside of the base 1, and a hydraulic lifting rod is provided inside the hydraulic drive component. The hydraulic lifting rod is driven by the aforementioned hydraulic drive component to drive the aforementioned base 1 up and down, thereby indirectly driving the screw up and down, facilitating displacement. Of course, it is not limited to using a hydraulic drive component and a hydraulic lifting rod to achieve up and down lifting of the base 1. Other methods that can enable the base 1 to achieve up and down lifting operations can also be used, such as using an electric motor to drive up and down, with the help of a transmission device such as a belt, gear or chain to achieve up and down lifting; or using a pneumatic system to drive a cylinder up and down with the help of compressed air; or using a mechanical transmission to achieve lifting with the help of a screw lifter or a combination of racks and gears.

[0025] In the embodiment of the present invention, the aforementioned mobile cart 3 is used to drive the aforementioned base 1 and the screw rod carried by the base 1 to move, which is convenient for loading and unloading the screw rods at different positions and locations. Specifically, the mobile cart 3 includes a base 301 and a traction rod 302 connected to one end of the base 301, and a traction handle 303 is provided at the end of the traction rod 302 for easy manual grip. In the embodiment of the present invention, the traction handle 303 is set as a slightly inclined slanted handle, which allows the user to maintain a natural wrist angle when pushing and pulling the mobile cart 3, reducing wrist discomfort and providing a better control experience.

[0026] In addition, a universal wheel 3010 is also connected to the bottom of the aforementioned base 301. The setting of the universal wheel 3010 allows it to move in multiple directions, whether front and back, left and right or diagonally, which makes it more convenient to move the trolley in a small space. Using the universal wheel 3010 is often easier to operate because the user only needs to push or pull it gently to change the direction without having to adjust the position significantly. The design of the universal wheel 3010 can also reduce ground wear. Compared with fixed wheels, the force required for movement is smaller, which helps to extend the service life of the ground. In the embodiment of the present utility model, a locking mechanism is also assembled on the universal wheel 3010, that is, a locking member 3011 is provided on the universal wheel 3010, which can be used to limit and fix the mobile trolley 3 when it stops moving, to prevent the trolley from slipping and avoid triggering dangerous accidents.

[0027] For the screw fixing seat 2, see Figure 2In this embodiment of the present invention, the screw holder 2 includes a lower receiving plate 201 and position-limiting end plates 202 perpendicularly disposed at either end of the lower receiving plate 201. The position-limiting end plates 202 are positioned in the same direction as the screw loading direction. The lower receiving plate 201 contacts the lower end of the screw, while the position-limiting end plates 202 abut against the two ends of the screw, thereby supporting the screw.

[0028] In this embodiment of the present invention, a threaded limit hole 2020 is provided on the aforementioned limit end plate 202, and a limit screw 2021 is threadedly connected to the threaded limit hole 2020 to further secure the screw. A handle 2022 is connected to one end of the limit screw 2021, i.e., the outer side of the limit end plate 202 (i.e., the end not in contact with the screw); a screw abutment 2023 is connected to the other end of the limit screw 2021, i.e., the inner side of the limit end plate 202 (i.e., the end abutting the screw). In this embodiment of the present invention, when the screw is loaded onto the screw fixing base 2, an operator rotates the handle 2022, thereby causing the limit screw 2021 to move accordingly within the threaded limit hole 2020. The specific movement distance is determined by the diameter of the loaded screw; as long as the screw abutment 2023 can be pressed against the side end of the screw, it is sufficient.

[0029] In addition, in the embodiment of the present invention, the screw abutment member 2023 is provided in a disc shape, which is intended to increase the contact area with the screw, reduce the pressure exerted by the screw abutment member 2023 on the screw, and avoid damage to the screw abutment member 2023. Of course, the operator can reasonably adjust the shape of the screw abutment member 2023 according to actual needs, as long as it can tightly abut the aforementioned screw. Therefore, the screw fixing seat 2 provided in the present invention can adapt to fixing screws of different diameters and masses, and has a simple structure and is easy to operate.

[0030] In the present invention, the screw rod abutting member 2023 may be made of plastic or metal, as long as it can clamp and fix the screw rod.

[0031] To sum up, the screw auxiliary disassembly device disclosed in the utility model sets the base on a movable trolley in a liftable manner, thereby realizing the lifting and movement of the screw during the assembly process, and at the same time uses an adjustable screw fixing seat to adapt to screws of different diameters. The device has a simple structure, strong adaptability, and is easy to operate.

[0032] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
