The length direction of the crossbeam 2 is parallel to a first direction. In use, the first direction is preferably horizontal. In the first direction, one end of the crossbeam 2 is the front end 21 and the other end is the rear end 22. Each end of the crossbeam 2 in the first direction is provided with a connecting device, so that the two connecting devices are distributed in sequence in the first direction. Each end of the crossbeam 2 is connected to the triangular connecting plates 1 at both ends of the tension composite insulator string 11 through a connecting device, so that the crossbeam 2 is located above the tension composite insulator string 11, and personnel can walk on the crossbeam 2 to avoid damage to the tension composite insulator string 11. The crossbar 2 includes two crossbars 23, multiple connecting rods 24, and two end rods 25. The crossbars 23 are parallel to a first direction, and the two crossbars 23 are spaced apart in a second direction.

The multiple connecting components 3 are spaced apart in the second direction. In this embodiment, each connecting device includes two connecting components 3. The connecting component 3 includes a plug-in seat 31 and two uprights 32. The plug-in seat 31 is used to install to the triangular connecting plate 1. In the first direction, one end of the connector 31 is an open end 311 and the other end is a closed end 312. A slot 313 is formed in the open end 311 of the connector 31. The slot 313 is used to insert the triangular connecting plate 1 in the first direction, and the slot 313 passes through the connector 31 in the second direction. During operation, the anti-stepping device is moved so that the triangular connecting plate 1 is inserted into the slot 313. The upright pole 32 is set vertically. One end of the upright pole 32 is fixedly connected to the plug-in seat 31, and the other end is fixedly connected to the cross frame 2. Specifically, the upright pole 32 is fixedly connected between the end pole 25 and the plug-in seat 31 so that there is a gap between the plug-in seat 31 and the cross frame 2 in the third direction. That is, there is a gap between the slot 313 and the cross frame 2 in the third direction. Therefore, when the operator steps on the cross frame 2, the tension composite insulator string 11 can be prevented from being damaged. Each plug-in socket 31 is provided with a corresponding locking component 4. The locking component 4 is connected to the open end 311 of the plug-in socket 31 to seal the slot 313 at the open end 311 of the plug-in socket 31. When the triangular connecting plate 1 is located in the slot 313, the plug-in socket 31 can be fixed to the triangular connecting plate 1 by sealing the open end 311 of the plug-in socket 31 with the locking component 4.

[0031] Reference Figure 5 and Figure 6 The locking component 4 includes a connecting post 41, a pin 42, a lever 43, and a pull ring 44. In the third direction, the connecting post 41 is fixedly connected to the side of the plug-in base 31 near the crossbeam 2. That is, when the anti-stepping device is installed on the triangular connecting plate 1, the connecting post 41 is fixedly connected to the top wall of the plug-in base 31, and the connecting post 41 is vertically arranged. The cross-section of the plug-in post can be circular or rectangular. In this embodiment, the cross-section of the plug-in post is rectangular, and two of the side walls of the plug-in post are perpendicular to the first direction, while the other two side walls are perpendicular to the second direction. The socket 31 has a pin hole 314 through the open end 311 along the third direction, and the pin hole 314 communicates with the slot 313; the connecting post 41 has a socket 411 communicating with the pin hole 314 along the third direction, the pin 42 is adapted to be located in the socket 411, and can slide in the socket 411 along the third direction under the guidance of the wall of the socket 411, and the pin hole 314 is used for the pin 42 to be inserted along the third direction; A guide groove 412 communicating with the insertion hole 411 is provided through the side wall of the connecting post 41. In this embodiment, the guide groove 412 is located on the side wall of the two connecting posts 41 in the connecting device that are close to each other. The guide groove 412 includes a vertical groove 4121 parallel to the third direction and a horizontal groove 4122 perpendicular to the third direction. In this embodiment, the horizontal groove 4122 is parallel to the first direction. In the third direction, the horizontal groove 4122 is located at the end of the vertical groove 4121 away from the insertion seat 31. The lever 43 is fixedly connected to the pin 42 and is set perpendicular to the pin 42. The lever 43 passes through the guide groove 412. The groove width of the horizontal groove 4122 and the vertical groove 4121 is consistent with the outer diameter of the lever 43, so that the lever 43 can move in the horizontal groove 4122 and the vertical groove 4121 under the guidance of the groove wall of the guide groove 412. When the lever 43 moves to the horizontal groove 4122, the pin 42 disengages from the pin hole 314. Pull ring 44 is located outside connecting post 41 and is fixedly connected to lever 43 to facilitate the operator to move lever 43. Pull ring 44 is located on the side of the two connecting posts 41 that are close to each other.

[0032] Reference Figure 4 , Figure 5 and Figure 7 In some embodiments of this application, an unlocking component 5 is also included. The unlocking component 5 includes an unlocking rod 51, a vertical rod 52, and a sliding rod 53. The unlocking rod 51 is parallel to the second direction and is located at the rear end 22 of the crossbeam 2. Each end of the unlocking rod 51 is fixedly connected to a pull ring 44. The vertical rod 52 is parallel to the third direction. One end of the vertical rod 52 is fixedly connected to the unlocking rod 51, and the other end is fixedly connected to the sliding rod 53. In the third direction, the unlocking rod 51 and the sliding rod 53 are located on the same side of the crossbeam 2, and in the third direction, the sliding rod 53 is located on the side of the unlocking rod 51 closer to the crossbeam 2. The sliding rod 53 is parallel to the first direction, and one end of the sliding rod 53 is fixedly connected to the vertical rod 52, and the other end extends to the front end 21 of the crossbeam 2. By moving the slider 53 along a third direction or a first direction, the vertical bar 52, the unlocking lever 51, the pull ring 44 and the lever 43 can be moved synchronously. When the lever 43 moves along a third direction, the lever 43 can be adjusted between the highest and lowest positions. When the lever 43 is in its highest position, the lever 43 and the transverse groove 4122 are at the same height. In this state, the lever 43 can be slid along the first direction into the transverse groove 4122 to fix the lever 43 and prevent the lever 43 from being inserted into the pin hole 314. When lever 43 is in its lowest position, lever 43 is inserted into pin hole 314.

[0033] A mounting base 6 is connected to the end rod 25 located at the front end 21 of the cross frame 2. A guide groove 61 is provided through the mounting base 6 along the first direction for the slide rod 53 to pass through. The length direction of the guide groove 61 is parallel to the third direction. The cross section of the slide rod 53 is rectangular. Guided by the groove wall of the guide groove 61, the slide rod 53 is slidably connected to the mounting base 6 along the third direction. The slide rod 53 can move in the first direction within the guide groove 61 so that the lever 43 can be driven by the slide rod 53 to move along the guide groove 412. In some embodiments, an elastic element 62 is provided between the slide rod 53 and the mounting base 6. When the elastic element 62 is in a deformed state, it stores a force that pushes the slide rod 53 to move along the third direction from the plug-in base 31 to the crossbeam 2. In this embodiment, the elastic element 62 is a compression spring, and in the third direction, the elastic element 62 is located on the side of the slide rod 53 away from the crossbeam 2. A second fixing element 63 is provided on the mounting base 6 for fixing the slide rod 53 and the lever 43 to the lowest position. The second fixing element 63 is a bolt. When the slide rod 53 presses the lever 43 to the lowest position, the second fixing element 63 passes through the mounting and is threadedly connected to the nut to press the slide rod 53 down.

[0034] The implementation principle of the composite tension insulator anti-trampling device used in construction according to an embodiment of this application is as follows: A helicopter or other mechanism is used to lift the crossbeam 2 and move the crossbeam 2 so that the triangular connecting plate 1 enters the slot 313. Of course, workers can also manually move the crossbeam 2 to position it. When installing the anti-trampling device on the triangular connecting plate 1, the front end 21 of the crossbeam 2 is close to the tower, and the rear end 22 of the crossbeam 2 is away from the tower. After the crossbeam 2 is in place, the plug-in seat 31 is fixed to the triangular connecting plate 1. When fixing the plug-in seat 31 of the front end 21 of the cross frame 2 to the triangular connecting plate 1, the operator stands on the tower and directly holds the lifting ring to insert the pin 42 into the pin hole 314. When fixing the plug-in seat 31 of the rear end 22 of the cross frame 2 to the triangular connecting plate 1, the operator stands on the tower and holds the unlocking rod 51 at one end of the front end 21 of the cross frame 2. Then, the slide rod 53 is moved along the horizontal groove 4122 to the top of the vertical groove 4121, and then the slide rod 53 is pressed down until the pin 42 is inserted into the pin hole 314. Finally, the slide rod 53 is fixed with the second fixing part 63.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
