[0008] As a limitation of this utility model: the screwing part also includes a screwing rod and a limiting rod. The screwing rod is fixed at the output end of the power component, and the limiting rod is fixed at the end of the screwing rod away from the power component. The outer contour of the limiting rod is adapted to the inner contour of the fastening sleeve. The fastening sleeve is sleeved on the outside of the limiting rod and is movably connected to the limiting rod. The direction of movement is set along the axial direction of the limiting rod.

[0009] A spring is fitted onto the screw rod, with the top end of the spring fixedly connected to the screw rod and the bottom end of the spring fixedly connected to the fastening sleeve.

[0010] As a further limitation of this utility model: the screwing part is provided in two sets, and the two sets of screwing parts are symmetrically arranged about the linear drive element.

[0011] As a further limitation of this utility model: the power component is a geared motor, and a torque sensor electrically connected to the geared motor is provided on the geared motor.

[0012] As another limitation of this utility model: the first moving member and the second moving member have the same structure. The first moving member includes a first connecting rod, which is hinged to the working end of the linear drive element. The end of the first connecting rod away from the linear drive element is hinged to a first sliding frame, which is slidably disposed on the mounting plate in the horizontal direction.

[0013] As a further limitation of this utility model: a sliding groove is provided on the mounting plate, the length direction of the sliding groove is perpendicular to the movement direction of the linear drive element, a first sliding frame is provided through the sliding groove, a first slider is provided between the first sliding frame and the sliding groove, the first slider is fixedly connected to the first sliding frame, and the sliding clip of the first slider is placed in the sliding groove.

[0014] As a further definition of the present invention: the second moving member includes a second connecting rod hinged to the working end of the linear drive element, and a second sliding frame hinged to the end of the second connecting rod away from the linear drive element; the bottom of the first sliding frame is bent toward the second sliding frame to form a first bent end, and the bottom of the second sliding frame is bent toward the first sliding frame to form a second bent end, the first bent end and the second bent end are used to clamp the track.

[0015] As a further limitation of this utility model: the linear drive element is an electrically controlled telescopic cylinder.

[0016] As a further limitation of this utility model: the bottom of the mounting plate is provided with a first limiting block and a second limiting block, which are used to lock the track.

[0017] As another limitation of this utility model: a mounting bracket is fixedly provided on the mounting plate, the mounting bracket is fixedly located in the middle of the mounting plate, and a lifting ring is fixedly provided on the top wall of the mounting bracket.

[0018] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0019] This utility model includes a mounting plate, on which a screwing part and a track clamping part are provided; the track clamping part includes a linear drive element, the working end of which is hinged to a first moving part and a second moving part, the first moving part and the second moving part move in opposite or opposite directions to clamp or release the track; the screwing part includes a power element fixed on the mounting plate, the output end of which is fixedly connected to a fastening sleeve, the fastening sleeve having a fastening groove extending along its axial direction, the size and shape of the fastening groove being adapted to the outer contour of the nut to be tightened;

[0020] During operation, the fastening sleeve is moved above the nut to be tightened. After the nut is engaged in the fastening sleeve, the electrically controlled telescopic cylinder is activated. The telescopic rod inside the cylinder extends upward. With the cooperation of the hinge and sliding groove structure, the first sliding frame and the second sliding rod move relative to each other. The first sliding frame and the second sliding rod clamp the track, restricting its movement in the up, down, forward, and backward directions. Then, the power component is activated. The rotation of the power component drives the fastening sleeve to rotate, thereby tightening the nut. This solves the problem of low efficiency in manually tightening nuts in the existing technology.

[0021] For assisting in the installation of high-altitude tracks, this invention can be combined with existing drones. The control of the electric telescopic cylinder and the power component can be achieved through drone wired or wireless control. The drone can be used to move the lifting ring to the track installation position, and then the drone can control the power component to start and tighten the nut. This solves the problem of inconvenient manual operation for high-altitude track installation in the prior art.

[0022] In summary, this invention enables automated tightening of nuts with high efficiency, and makes installation on high-altitude tracks simpler and faster. This invention is applicable to the railway or other rail transit industries, and is especially suitable for track installation work in cold and high-altitude environments.

[0035] The directional terms or positional relationships such as "up," "down," "left," "right," "front," and "back" used in the embodiments are based on the drawings in this utility model specification. Figure 1 The orientation relationships are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0036] like Figures 1-6 As shown, this embodiment includes a mounting plate 1, on which a screwing part 2 and a track clamping part 3 are provided; the screwing part 2 is used to screw on the nut, and the track clamping part 3 is used to clamp the track.

[0037] 1. Track clamping part 3;

[0038] like Figure 3 As shown, the track clamping part 3 includes a linear drive element 31 fixed on the mounting plate 1. In this embodiment, the linear drive element 31 adopts an electrically controlled telescopic cylinder, which is fixed on the mounting plate 1, and the telescopic rod inside the electrically controlled telescopic cylinder extends upward or retracts downward. Of course, the linear drive element 31 in this embodiment can also adopt any other structure that can realize linear drive in the prior art, such as a pneumatic cylinder or a hydraulic cylinder.

[0039] The working end of the linear drive element 31 is hinged to a first moving part 32 and a second moving part 33. Here, the working end refers to the extended end of the telescopic rod inside the electronically controlled telescopic cylinder. Specifically, as shown in the figure... Figure 3 , 5As shown, a lifting frame 37 is fixedly installed at the extended end of the telescopic rod. The first moving part 32 is located on the right side of the linear drive element 31, and the second moving part 33 is located on the left side of the linear drive element 31. The first moving part 32 and the second moving part 33 are both slidably mounted on the mounting plate 1. The first moving part 32 and the second moving part 33 move in opposite or opposite directions to clamp or release the track.

[0040] The first moving part 32 and the second moving part 33 have the same structure. Taking the first moving part 32 as an example:

[0041] like Figure 3 , 5 As shown, the first moving member 32 includes a first connecting rod 321, which is hinged to the working end of the linear drive element 31. That is, the left end of the first connecting rod 321 is hinged to the lifting frame 37. In this embodiment, a connecting shaft is fixed on the lifting frame 37. The left end of the first connecting rod 321 is sleeved on the connecting shaft and can rotate relative to the lifting frame 37. Since this hinge method is prior art, it will not be described in detail here. The end of the first connecting rod 321 away from the linear drive element 31 is hinged to a first sliding frame 322. A connecting shaft is also fixed on the upper end of the first sliding frame 322. The right end of the first connecting rod 321 is sleeved on the connecting shaft and can rotate relative to the first sliding frame 322. The first sliding frame 322 is slidably mounted on the mounting plate 1 in the horizontal direction. The sliding mounting method is as follows: a sliding groove 34 is provided on the mounting plate 1, see [link to relevant documentation]. Figure 3 , 4 The length direction of the slide 34 is perpendicular to the movement direction of the linear drive element 31. Here, the length direction refers to the left and right directions, and the movement direction of the linear drive element 31 is along the up and down directions.

[0042] like Figure 3 As shown, the first sliding frame 322 is disposed through the slide groove 34, and a first slider 323 is disposed between the first sliding frame 322 and the slide groove 34. The first slider 323 is fixedly connected to the first sliding frame 322, and a groove is formed on the first slider 323. (See Figure 1) Figure 1 The height of the groove is equal to or slightly greater than the height of the mounting plate 1. Here, the height refers to the distance in the up and down direction. The mounting plate 1 located on the edge of the slide groove 34 is inserted into the groove, so that the first slider 323 is placed in the slide groove 34.

[0043] The structure of the second moving part is the same as that of the first moving part 32, such as... Figure 3As shown, the second moving member 33 includes a second connecting rod 331 hinged to the working end of the linear drive element 31, and a second sliding frame 332 hinged to the end of the second connecting rod 331 away from the linear drive element 31. Specifically, the right end of the second connecting rod 331 is hinged to the lifting frame 37, and the left end of the second connecting rod 331 is hinged to the second sliding frame 332. The second sliding frame 332 passes through the slide groove 34 on the mounting plate 1 located on the left side of the linear drive element 31, and can slide horizontally, that is, slide in the left and right directions. The structure of the second sliding frame 332 and the second slider 333 is the same as that of the first sliding frame 322 and the first slider 323, and will not be described in detail here.

[0044] like Figure 3 , 4 As shown, the bottom of the first sliding frame 322 bends towards the second sliding frame 332 to form a first bent end 35, and the bottom of the second sliding frame 332 bends towards the first sliding frame 322 to form a second bent end 36. The first bent end 35 and the second bent end 36 are used to clamp the track. When the telescopic rod in the linear drive element 31 moves upward, the right end of the first connecting rod 321 and the left end of the second connecting rod 331 move relative to each other, and the first sliding frame 322 and the second sliding frame 332 move relative to each other to clamp the track and restrict the movement of the track in the up, down, forward, and backward directions. When the telescopic rod in the linear drive element 31 moves downward, the right end of the first connecting rod 321 and the left end of the second connecting rod 331 move away from each other, and the first sliding frame 322 and the second sliding frame 332 move away from each other to release the clamping of the track.

[0045] It should be noted that in this embodiment, the first sliding frame 322 slides relative to the mounting plate 1 through a slider. Of course, any other structure in the prior art can also be used, such as mounting a guide rail in the slide groove 34 and fixing a slider on the first sliding frame 322 to cooperate with the guide rail, as long as it can ensure that the first sliding frame 322 and the second sliding frame 332 slide relative to or away from each other.

[0046] II. Tightening part 2;

[0047] like Figure 3 , 6As shown, the screwing part 2 includes a power component fixed to the mounting plate 1 for rotational drive, a fastening sleeve 24 fixedly connected to the output end of the power component for tightening nuts, and a screwing rod 22, a limiting rod 23, and a spring 25. In this embodiment, the power component is a geared motor 21 as in the prior art. The output end of the geared motor 21 is fixedly connected to the screwing rod 22, which passes through the mounting plate 1. The top end of the screwing rod 22 is connected to the output end of the geared motor 21. The limiting rod 23 is fixedly located at the end of the screwing rod 22 away from the power component (i.e., the bottom end of the screwing rod 22). The fastening sleeve 24 is sleeved on the outside of the limiting rod 23 and movably connected to the limiting rod 23, with the moving direction along the axial direction of the limiting rod 23. A spring 25 is sleeved on the screwing rod 22, with the top end of the spring 25 fixedly connected to the screwing rod 22 and the bottom end of the spring 25 fixedly connected to the fastening sleeve 24.

[0048] The fastening sleeve 24 is provided with a fastening groove 241 extending along its axial direction. The size and shape of the fastening groove 241 are adapted to the outer contour of the nut to be tightened. Here, "adapted" means that the shape of the fastening groove 241 is hexagonal, which facilitates the rotation of the nut after it is engaged with the nut. The size of the fastening groove 241 is greater than or equal to the size of the nut so that the nut can be fully engaged in the fastening groove 241.

[0049] The outer contour of the limiting rod 23 is adapted to the inner contour of the fastening sleeve 24. This adaptation means that the outer contour of the limiting rod 23 is also hexagonal, ensuring that the fastening sleeve 24 can be fitted onto the limiting rod 23. In addition, since the limiting rod 23 and the fastening sleeve 24 are engaged, the fastening sleeve 24 can move up and down along the limiting rod 23, but cannot rotate relative to the limiting rod 23.

[0050] The reason for including the spring 25 and the limiting rod 23 in this device is that when the device is placed above the track, the fastening groove 241 inside the fastening sleeve 24 may not correspond to the shape of the nut when it first contacts the nut, and the nut will not be engaged in the fastening groove 241 at this time. When the reduction motor 21 drives the limiting rod 23 to rotate, the fastening sleeve 24 rotates accordingly. When the fastening sleeve 24 rotates until the fastening groove 241 corresponds to the shape of the nut, the spring 25, being in a compressed state, will press down on the fastening sleeve 24, causing the nut to be fully engaged in the fastening groove 241. By using a drone to fine-tune the position of this device, the installation location can be more accurately positioned, ensuring the accuracy of track installation.

[0051] Of course, if the nut can be inserted into the fastening groove 241 when the device is placed above the track, the fastening sleeve 24 can be directly fixed to the output end of the geared motor 21.

[0052] It should be noted that the screwing part 2 is set in two groups, and the two groups of screwing parts 2 are symmetrically arranged about the linear drive element 31, which can simultaneously screw the nuts located on both sides of the track.

[0053] To improve this embodiment, a torque sensor electrically connected to the geared motor 21 is provided on the geared motor 21. Figure 1-6 The torque sensor monitors the torque of the output shaft of the geared motor 21. When the nut is tightened, the torque sensor controls the geared motor 21 to automatically stop rotating, preventing the geared motor 21 from continuing to rotate after the nut is tightened, which could damage the geared motor 21. The structure of the torque sensor, its connection with the geared motor 21, and its working principle are existing technologies and will not be described in detail in this embodiment.

[0054] This device automatically positions and fixes the track using an electrically controlled telescopic cylinder and a geared motor 21, reducing manual operation and lowering labor costs. Furthermore, a torque sensor is used to detect whether the nuts are fully tightened, ensuring installation quality and enhancing reliability and stability.

[0055] III. Mounting bracket 4;

[0056] like Figure 1 As shown, manual operation is difficult during installation on high-altitude tracks. Therefore, a mounting frame 4 is also fixed on the mounting plate 1. A lifting ring 5 is fixed on the top wall of the mounting frame 4 for use with a drone. To enable the drone to move the device stably, the mounting frame 4 is fixed in the middle of the mounting plate 1. The mounting frame 4 has an inverted U-shaped structure and covers the electrically controlled telescopic cylinder.

[0057] It should be added that, such as Figure 1 , 3 As shown in Figure 4, the bottom of the mounting plate 1 is provided with a first limiting block 6 and a second limiting block 7. When the device is placed above the track, the first limiting block 6 and the second limiting block 7 can lock the track and prevent it from sliding left or right.

[0058] Working process: When installing high-altitude tracks, the drone connects to the lifting ring 5, which then moves this embodiment above the track. After the fastening sleeve 24 falls above the nut and is fitted onto it, the height of this device is lowered, causing the first limiting block 6 and the second limiting block 7 to lock onto both sides of the track. The electrically controlled telescopic cylinder actuates, causing the lifting frame 37 to move upward. The upward movement of the lifting frame 37 simultaneously causes the first connecting rod 321 and the second connecting rod 331 to move relative to each other, thereby causing the first sliding frame 322 and the second sliding frame 332 to move relative to each other until the first bending end 35 and the second bending end 36 clamp the track, restricting the track from moving in the forward, backward, up, and down directions. Subsequently, the reduction motor 21 actuates, causing the tightening rod 22 to rotate. The tightening rod 22 causes the limiting rod 23 and the fastening sleeve 24 to rotate, and the rotation of the fastening sleeve 24 causes the nut to rotate, thereby tightening the nut and thus assisting in the installation work. This device utilizes drones for positioning and operation, reducing the risks of manual high-altitude operations and improving the safety and efficiency of the work; it can meet the installation needs of different terrains.

[0059] After the twisting is completed, the electrically controlled telescopic cylinder reverses its movement, causing the first sliding frame 322 and the second sliding frame 332 to move in opposite directions, releasing the clamp on the track. Then, the UAV drives the device upward, waiting for the next twisting operation. Whether the twisting is completed can be determined by a torque sensor installed on the reduction motor 21.

[0060] It should be noted that the electronically controlled telescopic cylinder and the geared motor 21 can be connected to the power supply of the drone or powered by a separate battery. The electronically controlled telescopic cylinder can be controlled by the drone via wire or wireless control, which is an existing technology.

[0061] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
