Description

Technical Field

[0001] The present application relates to the field of soft ladder heads, and in particular to a soft ladder head for conductor maintenance operations. Background Art

[0002] In the power transmission system, conductors are usually connected between adjacent towers for power transmission and communication transmission. In order to ensure the stable operation of the power transmission system, the conductors need to be regularly inspected and maintained. During the operation, personnel need to make close contact with the conductors through the ladder head to inspect and maintain the conductors.

[0003] In the related art, a Chinese patent with application number 201320601585.3 discloses a self-locking soft ladder head, including a frame, a pulley device and a self-locking device, wherein the pulley device is symmetrically arranged at the upper end of the frame, and the lower end of the pulley device is provided with a self-locking device, wherein the self-locking device is composed of a locking tongue plate, a pin shaft, a load-bearing steel wire rope, an inner rail, an outer rail and a load-bearing pull ring device, wherein the load-bearing pull ring device includes a bracket, a bracket limit rod, a metal ring, a fixing cap, a fixing nut and a restoring spring. When in use, one end of the transmission rope is connected to the self-locking soft ladder head, and the other end is pulled by a ground operator through a pulley. During the ascent of the soft ladder head and the soft ladder, the load-bearing pull ring device transmits the external force received to the locking tongue plate through the load-bearing steel wire rope, so that it remains in an open state, thereby realizing the hook connection between the soft ladder head and the wire.

[0004] With respect to the above-mentioned related technologies, the inventor believes that when the ladder head is hung on the wire, the wire is located between the pulley and the locking tongue plate, but the peripheral wall of the pulley is circular, which leads to the defect that slippage is easy to occur between the pulley and the wire. Summary of the invention

[0005] In order to connect the soft ladder head to the conductor more firmly, the present application provides a soft ladder head for conductor maintenance operations.

[0006] The present application provides a soft ladder head for wire maintenance work, which adopts the following technical solution:

[0008] By adopting the above technical scheme, during operation, the hook is hung on the wire, and the personnel sit on the sliding frame. The sliding frame slides downward after bearing the weight, and the sliding frame drives the first connecting rod to rotate, the first connecting rod drives the second connecting rod to rotate, and the second connecting rod drives the self-locking rod to rotate synchronously. When the self-locking rod rotates to the opening of the hook, the wire can be fixed between the self-locking rod and the hook; after the self-locking component locks the wire, the side tipping of the soft ladder head on the wire can be reduced; after the self-locking component locks the wire, the driving member drives the re-locking rod to rotate until the wire is clamped between the re-locking rod and the hook; the wire is locked by arranging the self-locking rod, the hook and the re-locking rod, and the self-locking rod and the re-locking rod are located at both ends of the hook in the threading direction, so that the force direction of the wire is: the hook provides downward pressure on the wire, and the self-locking rod and the re-locking rod provide upward pulling force on the wire at both ends of the hook, respectively, so that the connection between the soft ladder head and the wire can be more stable.

[0009] Optionally, the driving member includes a first connecting seat, a gear, a first motor and a rack, the first connecting seat is fixedly connected to the hook, the gear is rotatably connected to the first connecting seat, the rack is fixedly connected to the locking rod, and the rack is meshed with the gear, and the first motor is used to drive the gear to rotate.

[0010] By adopting the above technical solution, when the driving member drives the locking rod to move, the first motor drives the gear to rotate. During the rotation of the gear, the rack moves toward one side to clamp the wire. This driving method can clamp the wire without manual operation by the operator, and the operation is more convenient.

[0011] Optionally, the hook assembly also includes an abutment wheel and a second motor, the abutment wheel is arranged in the opening of the hook, the area formed between the abutment wheel and the self-locking rod and the re-locking rod is used for allowing the wire to pass through, the abutment wheel is rotatably connected to the hook, and the second motor is used to drive the abutment wheel to rotate.

[0012] By adopting the above technical solution, when the ladder head needs to slide along the conductor, the second motor applies a torsional force to the rotating wheel, and the abutment wheel exerts downward pressure on the conductor. Therefore, the abutment wheel slides along the conductor, thereby driving the entire ladder head and the personnel to slide synchronously, making it convenient for the personnel to perform maintenance work on different positions of the conductor.

[0013] Optionally, a wire groove is coaxially formed on the peripheral wall of the abutment wheel.

[0014] By adopting the above technical solution, the wire is placed in the wire trough, and the two side walls of the wire trough have a certain limiting effect on the wire, which can effectively reduce the sideways tipping of the abutment wheel along the wire.

[0018] By adopting the above technical solution, when the wire is inclined, if the ladder head needs to climb upward along the wire, the clamping assembly will first clamp the wire, and then the first motor will drive the abutment wheel to rotate, thereby driving the ladder head to climb diagonally upward. After the abutment wheel climbs a certain distance, the clamping assembly will release the wire, and the first elastic member will restore its elasticity while driving the clamping assembly to move a certain distance toward the hook side. By arranging the clamping assembly, a certain protective effect is played when the abutment wheel and the wire slip, thereby protecting the operating safety of personnel.

[0019] Optionally, a first anti-slip pad is fixedly connected to a side of each clamping plate facing another clamping plate.

[0020] By adopting the above technical solution, the first anti-slip pad is provided to reduce the slipping between the clamping plate and the wire.

[0021] Optionally, a second anti-slip pad is fixedly connected to the inner wall of the wire trough.

[0043] The implementation principle of a soft ladder head for wire maintenance work in an embodiment of the present application is: during operation, the hook 21 is hung on the wire, and the wire is located in the wire groove 231. After the hook 21 is hung on the wire, the operator wears a shielding suit and sits on the sliding seat 13, thereby driving the sliding seat 13 to move downward. When the sliding seat 13 moves downward, it drives the first connecting rod 31 to rotate. When the first connecting rod 31 rotates, it drives the second connecting rod 32 to rotate. When the second rotation occurs, it drives the self-locking rod 33 to rotate synchronously, thereby driving the self-locking rod 33 to rotate to the opening of the hook 21, and the wire can be clamped between the self-locking rod 33 and the abutment wheel 23.

[0044] After the self-locking rod 33 closes the open end of the hook 21, the first motor 413 drives the gear 412 to rotate, and the gear 412 rotates and drives the rack 414 to slide upward, and the rack 414 slides upward and drives the re-locking rod 42 to move upward synchronously; after the re-locking rod 42 moves upward, the force on the wire is: the abutment wheel 23 applies downward pressure to the wire, and the self-locking rod 33 and the re-locking rod 42 both apply upward lifting force to the wire, so that the wire can be fixed. After the wire is fixed, the operator can perform maintenance work.

[0045] When the ladder head needs to slide along the wire, the clamping assembly 5 first clamps the wire, and then the first motor 413 drives the locking rod 42 to move downward until a gap is created between the locking rod 42 and the wire, and then the second motor 22 drives the abutment wheel 23 to rotate. When the abutment wheel 23 rotates, it drives the hook 21 to slide along the wire. After sliding for a distance, the first motor 413 drives the locking rod 42 to move upward to tighten the wire. After the locking rod 42 tightens the wire, the clamping assembly 5 releases the wire. At this time, the second elastic member 14 restores its elasticity, and the clamping assembly 5 can be slid toward the hook 21 for a distance. Then, the above operation is repeated until the hook 21 slides to the desired position.

[0046] When the clamping assembly 5 clamps the wire, the third motor 54 drives the bidirectional screw 53 to rotate forward, and the bidirectional screw 53 rotates forward to drive the two clamping plates 55 to move toward the opposite side, so that the wire can be clamped; when the clamping assembly 5 loosens the wire, the third motor 54 drives the bidirectional screw 53 to rotate reversely to drive the two clamping plates 55 to move toward the opposite side, so that the wire can be loosened.
