Description

Technical Field

[0001] The invention belongs to the field of safety devices, and in particular relates to a flexible track anti-falling device. Background Art

[0002] In the power industry, towers serve as crucial support structures for transmission lines. Line maintenance and installation operations often require workers to climb to varying heights. To ensure worker safety, a flexible track (such as a wire rope) combined with a self-locking device is currently used. This method uses the wire rope to form a flexible track extending along the tower, and workers use the self-locking device to move along the wire rope, providing fall protection.

[0003] However, there are many deficiencies in the coordination between the flexible track and the tower in the existing technology: the connection between the wire rope and the tower mostly adopts simple binding or a single fixing part, which is difficult to adapt to the complex shape of the tower steel frame (such as square tubular structure, right-angle steel structure), and is easily loosened due to vibration, external force, etc., causing the wire rope to shake, affecting the balance of the operators; the specifications of the tower steel frame (such as pipe diameter, thickness) are different, and the position and clamping force of the existing fixing device are difficult to flexibly adjust, and cannot be adapted to tower structures of different specifications, and has poor versatility; when the climbing self-locking device moves on the wire rope, if the wire rope has no interval limit structure, it may accidentally slide directly to the bottom of the tower, causing a safety accident. Summary of the Invention

[0004] The present invention mainly solves the above technical problems.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: the flexible track anti-fall device proposed in the present invention includes an iron tower steel frame and an output rope device, the iron tower steel frame adopts a right-angle steel structure, the output rope device includes a base fixed to the ground, a winch is provided on the base, and a mounting groove is opened on the inner side of the base. The winch and the mounting groove on the inner side of the base are in a relatively movable and rotating structure, and a split structural design is adopted to facilitate disassembly and transportation. The steel wire rope is wound around the winch, and one end extends from the winch. It is characterized in that it also includes an auxiliary locking mechanism, a clamping assembly and a wire clamping mechanism:

[0009] The wire clamping mechanism is arranged at the other end of the connecting frame, and the wire clamping mechanism includes a clamping plate, which is hinged to the connecting frame and is movably clamped to the connecting nut.

[0010] Furthermore, a bent plate is fixedly provided at one end of the connecting frame, and forms a C-shaped structure with the connecting frame.

[0011] Furthermore, the clamping assembly includes a clamping column and a clamping nut, the clamping nut is fixed on the bending plate, the vertical thread of the clamping column passes through the clamping nut and the bending plate, and is movably connected to the tower steel frame.

[0012] Furthermore, one end of the auxiliary locking frame is set as a stud structure and is slidably arranged with the slide groove, and the other end is set as a fork structure with two bent columns, wherein the stud structure and the fork structure are respectively arranged on both sides of the slide groove, and are movably connected to the tower steel frame.

[0013] Furthermore, the auxiliary locking mechanism further comprises a locking nut and a washer, the washer is slidingly connected to one side of the auxiliary locking frame stud structure, and the locking nut is threadedly connected to one side of the auxiliary locking frame stud structure.

[0014] Furthermore, the wire clamping mechanism also includes a connecting bolt and a connecting nut, the connecting bolt slides through the clamping plate and the connecting frame in sequence, and the connecting nut is threadedly connected to the end of the connecting bolt.

[0015] Furthermore, a storage structure is provided on the connecting frame, and the storage structure includes a jack and a socket.

The auxiliary locking frame stud structure and the jack are relatively slidably arranged, and the auxiliary locking frame has a fork-shaped structure with two bending columns, in which one bending column and the socket are movably arranged.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows:

[0017] 1. The flexible track anti-fall device proposed in this plan forms a clamp from both sides of the tower steel frame through the clamping assembly and the auxiliary locking mechanism. Combined with the wrapping effect of the C-shaped connecting frame, it significantly improves the fixing stability of the connecting frame and the tower steel frame and prevents the shaking of the wire rope. In addition, the various components are coordinated through threaded connections, hinges, etc., and the installation and disassembly process is simple.

[0019] 3. The flexible track anti-fall device proposed in this plan can form interval limits for the wire rope by setting multiple connecting frames at the top, middle and bottom of the tower steel frame, preventing the climbing self-locking device from accidentally sliding to the bottom, thereby reducing the risk of use.

[0020] 4. The flexible track anti-fall device proposed in this solution can store the auxiliary locking frame on the connecting frame when not in use through the jacks and sockets of the storage structure, thereby avoiding loss of components and saving space. BRIEF DESCRIPTION OF THE DRAWINGS
