[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] like Figure 1 and Figure 3 As shown, the embodiment of the utility model provides a screw turning device, which includes: a base 10 and a support portion 20. Among them, the support portion 20 includes two limit assemblies 21, and the two limit assemblies 21 are arranged on the base 10 with an adjustable spacing to facilitate the maintenance of screws 100 of different diameters. The two limit assemblies 21 cooperate with each other to support and limit the screw 100, while preventing the screw 100 from directly contacting the base 10 to cause wear to it, and reducing the risk of the screw 100 rolling off the base 10 during maintenance.

[0027] By applying the technical solution of the utility model, the screw turning device includes a base 10 and a support part 20. Among them, the support part 20 includes two limit assemblies 21, and the two limit assemblies 21 are arranged on the base 10 with an adjustable spacing, and the two limit assemblies 21 cooperate with each other to support and limit the screw 100. Through the above design, the support part 20 is arranged on the base 10 to support the screw 100, and the two limit assemblies 21 are used to limit the screw 100, which can reduce the risk of the screw 100 falling from the base 10 during maintenance, and the spacing between the two limit assemblies 21 is adjustable. In this way, by adjusting the distance between the two limit assemblies 21, it is possible to adapt to the support and limitation of screws 100 of different diameters, thereby improving the maintenance efficiency of the screw 100.

[0028] Specifically, the support part 20 also includes a movable seat 22, which has a relatively set sliding state and a fixed state, and the limit assembly 21 is arranged on the movable seat 22, and the movable seat 22 is used to drive the limit assembly 21 to move on the base 10. Through the above arrangement, before the screw 100 is removed from the extruder and placed on the base 10, the movable seat 22 is placed in a sliding state to adjust the distance between the two limit assemblies 21 so that the screw 100 can be placed between the two limit assemblies 21. Then, the movable seat 22 is controlled to switch to a fixed state, and the two limit assemblies 21 are used to support and limit the screws 100 of different thicknesses, so as to facilitate the maintenance of the screw 100.

[0029] The limiting assembly 21 includes a limiting roller 211, and the limiting rollers 211 of the two limiting assemblies 21 are arranged parallel to each other. Through the arrangement of the limiting roller 211, when the screw 100 is turned, the contact surface of the limiting roller 211 and the screw 100 is a circular curved surface. Compared with the special-shaped surface, the structure of the present application makes the rotation of the screw 100 smoother, reduces the waste of manpower, and improves the convenience of turning the screw 100. The limiting rollers 211 are arranged parallel to each other, and the two limiting assemblies 21 are respectively arranged on both sides of the screw 100 to ensure the balance of the screw 100. In this way, the reserved pores between the two limiting assemblies 21 will also be more compatible with the structural shape of the screw 100, improve the support performance and limiting performance of the screw 100, ensure the stability of the screw 100 on the base 10 during maintenance, and prevent the screw 100 from falling and injuring the operator during turning.

[0030] In the present application, the support part 20 also includes a bearing 23, the movable seat 22 is provided with a bearing 23, the limiting roller 211 is provided in the bearing 23, and the limiting roller 211 is rotatably connected to the movable seat 22 through the bearing 23. Through the above arrangement, the limiting roller 211 can adjust the relative position with the movable seat 22, and can also rotate relative to the screw 100, so as to avoid the screw 100 from getting stuck during rotation, further improve the smoothness of the screw 100 rotation, and thus improve the maintenance efficiency of the screw 100. At the same time, the friction between the screw 100 and the limiting assembly 21 is also reduced when the screw 100 rotates, thereby extending the service life of the support part 20.

[0031] like Figure 2 As shown, the bearing 23 has an inner ring 231 and an outer ring 232 arranged relatively, the limiting roller 211 has a main shaft 2111, the main shaft 2111 and the inner ring 231 of the bearing 23 are interference-fitted, and the movable seat 22 and the outer ring 232 of the bearing 23 are interference-fitted, and the rotation connection between the limiting roller 211 and the movable seat 22 is realized through the above-mentioned cooperation. Such a structure is simple, and it is very convenient to disassemble and assemble without reinstalling equipment, and it can be operated by one person, and the processing is simple, saving the manufacturing cost of the entire device.

[0032] Furthermore, a slide groove 11 is provided on the base 10, and the movable seat 22 is movably arranged in the slide groove 11. Through the above arrangement, the movable seat 22 can move more smoothly on the base 10, and the slide groove 11 can provide guidance and limit for the movement of the movable seat 22, so as to prevent the movable seat 22 from being offset when driving the limit assembly 21 to adjust the position, resulting in a reduction in the adaptability of the placement of the limit assembly 21 and the screw 100, thereby reducing the smoothness of the rotation of the screw 100 when the screw 100 is turned. In other embodiments of the present application, the movable seat 22 and the base 10 can also be engaged by snap-fitting or rack fitting, etc., so that the position of the movable seat 22 on the base 10 can be adjusted.

[0033] Among them, movable seats 22 are provided at both ends of the limiting roller 211, so that the two ends of the limiting roller 211 can be adjusted synchronously to ensure the stability of the limiting roller 211 when moving and rotating and the coordination of the two ends. Two slide grooves 11 are provided on the base 10, and the two slide grooves 11 are respectively located at the two ends of the limiting roller 211, and multiple movable seats 22 are correspondingly arranged in the two slide grooves 11. Through the above arrangement, the two limiting rollers 211 can always move on the same horizontal plane and the same track, that is, they only move relative to each other along the slide grooves 11, that is, the limiting rollers 211 are symmetrically distributed on both sides of the screw 100, so that the force on both sides of the screw 100 is uniform and balanced, avoiding the occurrence of uneven force on the screw 100 when rotating, resulting in deviation and the like, and improving the stability of the support for the screw 100.

[0034] In the present application, the movable seat 22 includes a body 221 and two sliders 222, the two sliders 222 are respectively located on both sides of the body 221, the limiting roller 211 is connected to the body 221, the two sliders 222 are movably connected to the slide groove 11, and a fastener 223 is provided between each slider 222 and the slide groove 11, and the fastener 223 can fix the position of the slider 222 in the slide groove 11. Through the above arrangement, the switching of the movable seat 22 between the sliding state and the fixed state is realized through the cooperation of the fastener 223 and the slide groove 11, and the structure is simple and easy to operate. In the present application, the slide groove 11 is set as a through groove passing through the base 10, and the fastener 223 is a combination of a bolt and two nuts. The bolt is passed through the slider 222 and the length of the bolt is greater than the thickness of the base 10. When the movable seat 22 is adjusted to a suitable position and needs to be switched from a sliding state to a fixed state, it is only necessary to tighten the nut at the end of the bolt at the lower part of the base 10. When the position of the movable seat 22 needs to be adjusted, the nut below is loosened, and the movable seat 22 can be easily switched between the sliding state and the fixed state at any time.

[0035] Specifically, the structure of the main body 221 is an arc-shaped structure that is compatible with the bearing 23, so that the rotation coordination between the movable seat 22 and the bearing 23 and the main shaft 2111 of the limiting roller 211 is smoother, avoiding jamming when the limiting roller 211 rotates with the screw 100, thereby affecting the maintenance efficiency of the screw 100.

[0036] like Figure 3 As shown, the screw turning device also includes a telescopic support 30 and a universal wheel 40. Among them, one end of the telescopic support 30 is connected to the bottom of the base 10, and the telescopic support 30 can drive the base 10 to rise and fall. In the prior art, the screw is placed on the sleeper after being pulled out. When the sleeper pad under the screw is too low, it is inconvenient to inspect the screw, and when the pad is too high, it is easy to cause the sleeper to collapse or the screw to slip. Through the setting of the telescopic support 30, the height of the base 10 can be adjusted arbitrarily in real time, and the height of the device can be adjusted at any time according to the height of the operator or the operation content, which is convenient for the cleaning and coloring inspection of the screw 100. The universal wheel 40 is set at the other end of the telescopic support 30 to move the base 10. In the prior art, after the screw is pulled out, it needs to be transferred to the maintenance area. The electric hoist above the extruder needs to be used to pull the screw obliquely and crookedly. Hoisting accidents are prone to occur during the transfer process, and the range of transfer is limited. By providing the universal wheel 40, after the extracted screw 100 is stably placed on the support part 20, the screw 100 can be directly transferred by controlling the moving direction and direction of the universal wheel 40, and the transfer range is not limited, and the screw 100 can be moved and stopped at any time.

[0037] Among them, the base 10 and the support part 20 form a group of support components, and the screw 100 turning device includes multiple support components, and the multiple support components cooperate with each other to support the screw 100. Setting it as multiple groups can improve the stability of the placement of the screw 100, avoid the screw 100 from falling and injuring people during maintenance or transfer, and affect the maintenance efficiency, and the spacing between each support component can also be adjusted so that the device is suitable for the maintenance of screws of different lengths. The number of support components is not limited in this application, and it is sufficient to stably support the screw 100. In this embodiment, the support components are set to two, which are placed at both ends of the screw 100 for support. A cavity 12 is also provided on the upper part of the base 10, leaving a larger rotation space for the limit roller 211, and it is convenient to replace the limit roller 211 of different diameters to adapt to screws 100 of different weights and sizes, making the device more compact. At the same time, the overall weight of the device can be reduced, which is convenient for movement.

[0038] Furthermore, the winching device also includes a lifting lug 50 and a winching rod 60. The lifting lug 50 is used to connect with the threaded hole at the end of the screw rod 100, which is convenient for disassembly at any time, and the threaded connection is more secure. When the screw rod 100 is turned along the threaded structure, the lifting lug 50 can be prevented from coming out. The winching rod 60 is arranged on the lifting lug 50, and the winching rod 60 is used to drive the screw rod 100 to rotate on the support part 20. In this way, the lifting lug 50 and the winching rod 60 of the corresponding size can be selected according to the screw rods of different size structures, which is convenient for disassembly and assembly. In other embodiments of the present application, the screw rod can also be turned and repaired by electric equipment.
