[0024] Example:

[0025] See also Figure 1-4 , the utility model provides a technical solution:

[0026] A composite steering device suitable for preventing power transmission line towers from falling comprises a turntable body 1, an angle steel fixing fixture 2 being fixed to the rear side wall of the turntable body 1, two sets of symmetrical screws 3 being fixed to the side walls of the angle steel fixing fixture 2, the two sets of symmetrical screws 3 being provided with conical lock buckles 4 on the outside, and a fastening nut 5 being provided on the outside of the screw 3 and located next to the conical lock buckle 4. During the actual operation of the angle steel fixing fixture 2, the shape and size of the tower and the steel frame structure are different. The front end of the conical lock buckle 4 in the angle steel fixture is conical in shape and can adapt to the locking of angle steels of different specifications on the tower, and the position of the conical lock buckle 4 can be adjusted in the fixture to achieve the locking of angle steels of different specifications. The turntable body 1 and the angle steel are locked to the tower by the angle steel fixture, and the structure is simple, the strength is good, and the installation is easy.

[0027] A first rigid guide rail blade bracket 6 is fixed to the left and right ends of the front side wall of the turntable body 1, and a horizontal rigid guide rail 7 is arranged inside the two first rigid guide rail blade brackets 6. A second rigid guide rail blade bracket 8 is fixed to the upper and lower ends of the front side wall of the turntable body 1, and a vertical flexible guide rail 9 is arranged inside the two second rigid guide rail blade brackets 8; the first rigid guide rail blade bracket 6 and the second rigid guide rail blade bracket 8 use cold pressing technology to fix the vertical flexible guide rail 9 and the horizontal rigid guide rail 7 on the bracket, and the blade bracket also serves as a carrier for the anti-fall device 13 to transition from bottom to top to move from left to right, so that the anti-fall device 13 can move freely in multiple directions, thereby increasing the protection range.

[0028] A rotating core 10 is rotatably provided at the front end of the turntable body 1, and a spring plunger 11 is provided on the side wall of the rotating core 10. A plunger positioning groove is provided on the front side wall of the turntable body 1, and the rear end of the spring plunger 11 is engaged with the plunger positioning groove. A rotating core guide rail 12 is provided on the front side wall of the turntable core 10, and a fall arrester 13 is provided on the outside of the rotating core guide rail 12. The fall arrester 13 moves from the vertical flexible guide rail 9 to the rotating core guide rail 12. When the rotating core turns, when it rotates to a 45° position, there is an anti-slip limit baffle 14 on the turntable body 1 to prevent the fall arrester 13 from falling out during rotation.

[0029] The composite diverter suitable for preventing transmission line towers from falling has the following advantages:

[0030] The structural design of the "adaptive" angle steel clamp can adapt to angle steels of different specifications. Its conical lock buckle 4 can not only adjust the position in the clamp to lock angle steels of different specifications, but also the locking force of the conical lock buckle 4 on the angle steel becomes stronger the tighter it is used. It has a simple structure and high strength.

[0031] The blade support structure is designed to connect both the flexible and rigid guide rails in the diverter. The connection is achieved through cold extrusion, resulting in a non-detachable joint, high structural strength, and low cost. It also serves as an intermediate carrier for the vertical flexible guide rail 9 to be transferred to the horizontal rigid guide rail 7. The overall structure is flexible, lightweight, and easy to operate.

[0032] The turntable body 1 allows all its components to be connected together, making the structure easy to install. The turntable body 1 is equipped with an anti-slip block 14, which effectively prevents the device from slipping out or falling off during the transition from the vertical flexible guide rail 9 to the horizontal rigid guide rail 7. The structural design is ingenious.

[0033] A rotating center design with positioning is adopted, and a spring plunger 11 is provided in the rotating center to realize the positioning function. It only allows the rotating center to rotate clockwise in the vertical direction, and the maximum rotation angle of the rotating core is 90°. When it can no longer rotate, it means that the spring plunger 11 on the rotating center has completed the positioning, and the steering process of the entire process is completed, achieving the effect of accurate steering and easy operation.

[0034] The design features a maximum 90° rotation positioning mechanism. A spring-loaded plunger 11 is installed within the rotor to facilitate positioning, allowing the rotor to rotate up to a maximum of 90°. When the rotor rotates 90° clockwise, the spring-loaded plunger 11 automatically drops to its designated position, completing the positioning. This 90° maximum rotation positioning mechanism allows the rotor guide rail 12 to accurately switch from vertical to horizontal orientation, ensuring smooth vertical movement of the arrester 13 before reversing direction. Furthermore, after reversing direction, the arrester 13 can also move smoothly left and right. This ensures precise steering and switching, as well as easy operation.

[0035] The conical lock buckle 4 is slidably arranged outside the screw rod 3 , and the side wall of the fastening nut 5 contacts the side wall of the conical lock buckle 4 .

[0036] The rotating core 10 is on the front side of the turntable body 1 and can only rotate clockwise, and the maximum angle of rotation of the rotating core is 90 degrees. When the rotating core 10 rotates clockwise, the spring plunger 11 and the rotating core guide rail 12 rotate to 90° and just reach the spring plunger positioning groove. Under the action of the spring, the plunger falls and is stuck in the positioning groove, completing the positioning and guiding of the rotating core for 90° rotation.

[0037] When the core guide rail 12 is rotated vertically, it is matched with the two vertical flexible guide rails 9 . When the core guide rail 12 is rotated horizontally, it is matched with the two horizontal rigid guide rails 7 .

[0038] The spring plunger 11 includes a spring and a plunger. The spring is fixedly arranged inside the rotating core 10. The other end of the spring is fixedly connected to the side wall of the plunger. The plunger is slidably connected to the side wall of the rotating core 10. The rear side wall of the plunger is plugged into the plunger positioning groove.

[0039] Anti-slip limit baffles 14 are fixed to the lower left end and the upper right end of the turntable body 1.

[0040] Working principle:

[0041] First, insert the angle steel fixture turntable into the corresponding buckle position of the mounting plate body 1, and lock the angle steel on the tower with the cone-shaped lock buckle 4. After tightening the fastening nut 5 of the fixture, the anti-fall device 13 first moves in the vertical flexible guide rail 9 to the position of the second rigid guide rail blade bracket 8, and is guided by the second rigid guide rail blade bracket 8 to move to the rotating core guide rail 12. Fix one end of the vertical flexible guide rail 9 on the second rigid guide rail blade bracket 8, and the other end on the tower. Install the anti-fall device 13 in the vertical flexible guide rail 9 and start moving the anti-fall device 13 upward. Go, connect to the core guide rail 12 through the second rigid guide rail blade bracket 8, when the core 10 rotates clockwise with the spring plunger 11 and the core guide rail 12 rotates to 90°, it just reaches the spring plunger positioning groove, and under the action of the spring, the plunger falls and is stuck in the positioning groove, completing the positioning guide of the core 90° rotation. The core 10 is provided with an anti-slip and limiting mechanism, so it can only rotate in one direction clockwise, and the maximum rotation angle is 90°, which can effectively prevent the anti-fall device 13 from being inverted or falling off. The core 10 is provided with a guide positioning mechanism to guide the anti-fall device 13 to pass through the guide rail smoothly.

[0042] After the fall arrester completes a 90° turn, the spring plunger reaches the spring plunger positioning slot. Under the action of the spring, the plunger drops and engages the positioning slot, securing the center of rotation and preventing further rotation that could cause the fall arrester to fall off. The fall arrester, guided by the blade bracket, enters the rigid guide rail and continues to move left and right. One end of the rigid guide rail is fixed to the turntable blade bracket, and the other end is fixed to the tower.
