Description

Technical Field

[0001] The invention belongs to the field of wire-laying pulleys, and in particular relates to a wire-laying pulley with a remote control unlocking function. Background Art

[0002] In the construction process of high-voltage overhead transmission lines, the wire-laying pulley, as an indispensable construction equipment, plays a vital role. It can not only effectively protect the wires from wear and damage, but also significantly improve the work efficiency of the entire wire-laying construction, ensuring the safe and stable laying of the transmission line. The traditional wire-laying pulley design mainly focuses on the smooth transmission of the wire and the improvement of the carrying capacity. After the wire is laid, the lock and unlocking of the pulley often rely on manual operation.

[0003] Specifically, when the wire is successfully laid along the predetermined path, the lock on the wire-laying pulley needs to be unlocked to release the wire from the pulley and continue the subsequent line connection work. For those cases where the wire-laying pulley is directly suspended on the transmission tower, although there are certain risks and challenges in high-altitude operations, construction workers can usually climb the tower to approach the pulley position and manually perform the unlocking operation. Although this process is difficult, it is relatively feasible and the cost is controllable.

[0004] However, with the development of construction technology, especially when constructing power transmission lines in complex terrain or densely populated urban areas, the wire-laying pulley sometimes needs to be suspended on a crane for operation to avoid ground obstacles or improve construction flexibility. In this case, the traditional unlocking method is inadequate. Due to the length of the crane boom and the limitations of the operating range, it is difficult for construction workers to climb directly to the vicinity of the wire-laying pulley to unlock it. In order to complete this task, it is often necessary to use another crane to send the construction workers to the side of the wire-laying pulley through hoisting operations, which not only greatly increases the difficulty of construction and reduces work efficiency, but also significantly increases the manpower and equipment costs of the project; in addition, the complexity of the high-altitude working environment, such as wind influence, line of sight restrictions, and narrow operating space, further aggravates the danger of remote control unlocking operations. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a wire-laying pulley with a remote control unlocking function to solve the problems of low unlocking efficiency, high construction cost and great danger when a wire-laying pulley is suspended by a crane in the prior art.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A wire-laying pulley with a remote control unlocking function comprises a U-shaped main frame, a top plate is provided on the upper part of the U-shaped main frame, one end of the top plate is pivotally connected to the U-shaped main frame through a pin shaft, a hanging plate is provided on the upper part of the top plate, a hanging groove is provided on the hanging plate, the lower end of the sling is suspended in the hanging groove, a pulley assembly is provided inside the U-shaped main frame, the pulley assembly comprises a main shaft, the main shaft is rotatably mounted inside the U-shaped main frame, a plurality of pulley wheels are provided on the main shaft, wherein the middle pulley wheel is a wire rope wheel, and the pulley wheels on both sides are guide wire wheels; a blocking plate is connected to one side of the U-shaped main frame through a plurality of hinges, and the blocking plate The U-shaped main frame can be flipped around the hinge to close or open one side of the U-shaped main frame; a remote control lock is provided on the side of the top plate close to the blocking plate, a lock hole is provided on the top of the blocking plate, the lock hole corresponds to the position of the lock tongue of the remote control lock, and the remote control lock is internally provided with a power supply for providing electric energy to the remote control lock, a driving mechanism for driving the lock tongue to be extended and retracted, and a signal receiving module for remote control, and also includes a remote control, and the signal receiving module is connected to the remote control via wireless communication; after the signal receiving module receives the remote control signal of the remote control, the driving mechanism is controlled to drive the lock tongue to be extended and retracted, so that the lock tongue is inserted into the lock hole or withdrawn from the lock hole.

[0008] Furthermore, the suspension groove is a V-shaped structure, one end of the suspension groove is colinear with the center of gravity of the wire-paying pulley, and the lower end of the hanger is suspended at this end when the wire is unrolled; the other end of the suspension groove deviates from the center of gravity of the wire-paying pulley and is away from the blocking plate. After the blocking plate is opened, the blocking plate flips around the hinge to one side of the U-shaped main frame, and the center of gravity of the wire-paying pulley shifts to the side away from the blocking plate, the wire-paying pulley is tilted and deflected, and the hanger slides from one end of the suspension groove to the other end.

[0009] Furthermore, an anti-hanging block is provided on one side of the blocking plate, and the anti-hanging block is a triangular prism structure. A counterweight block is provided on the other side of the blocking plate, and the weight of the counterweight block is greater than the weight of the anti-hanging block. The anti-hanging block and the counterweight block are both made of nylon material. After the blocking plate is flipped to the lower part of the U-shaped main frame, the counterweight block blocks the gap between the blocking plate and the side wall of the U-shaped main frame.

[0010] Furthermore, a limit baffle is provided at the lower part of the top plate, and when the blocking plate abuts against the limit baffle, the positions of the lock tongue and the lock hole correspond.

[0011] Furthermore, a brush is provided at the lower part of the U-shaped main frame, and the bristles of the brush are in contact with the pulley wheel.

[0012] Furthermore, a lifting ring is provided on one side of the lower part of the U-shaped main frame, the lifting ring is located on the side away from the blocking plate, and a pull rope is wound around the lifting ring.

[0013] Furthermore, a torsion spring is provided in the middle of the hinge, which causes the blocking plate to flip toward the lower part of the U-shaped main frame in a natural state. When the blocking plate closes the opening of the U-shaped main frame, the torsion spring is in a stressed state. After the remote control lock unlocks the blocking plate, the blocking plate automatically flips under the action of the torsion spring.

[0014] Furthermore, a protective component is provided on the upper part of the pulley, and the protective component includes a roller shaft, and a nylon roller is rotatably installed on the outside of the roller shaft; a fixed plate is connected to one side of the roller shaft, and a guide block is connected to one side of the fixed plate. A guide groove is provided on the side wall of the U-shaped main frame, and the guide block is slidably installed in the guide groove. A screw is threadedly connected to one end of the guide block, and both ends of the screw are rotatably connected to the side wall of the U-shaped main frame through a support, and a knob is connected to one end of the screw.

[0015] Furthermore, it also includes a flipping assembly, which includes a fixed seat, a telescopic driving mechanism is provided on one side of the fixed seat, the telescopic driving mechanism is connected to the remote control through a wireless communication module, one end of the telescopic driving mechanism is connected to a connecting plate, a rack is provided at the lower part of the connecting plate, a gear is meshed at the lower part of the rack, the gear is fixedly installed on one end of the pin shaft, and the pin shaft is fixedly connected to the upper end of the U-shaped main frame.

[0016] Furthermore, the telescopic driving mechanism is a hydraulic cylinder, a pneumatic cylinder or an electric push rod.

[0017] The beneficial effects of the present invention are:

[0018] 1) The present invention realizes remote unlocking of the blocking plate by arranging a remote control lock on the U-shaped main frame and controlling the locking of the remote control lock by a remote controller, thereby solving the problems of low unlocking efficiency, high construction cost and high risk when the wire-laying pulley is suspended by a crane; in addition, when the wire-laying pulley is suspended on the iron tower, it is also beneficial to reduce the time of high-altitude operations and reduce the risks of operations.

[0019] 2) The suspension groove is designed to be a V-shaped structure. After the blocking plate is opened, the blocking plate flips around the hinge to one side of the U-shaped main frame, so that the center of gravity of the wire-paying pulley is shifted to the side away from the blocking plate, the wire-paying pulley is tilted and deflected, and the hanger slides from one end of the suspension groove to the other end, further increasing the inclination of the wire-paying pulley, making it easier to separate the wire from the pulley wheel, thereby allowing the wire to slide out from the open side of the U-shaped main frame.

[0020] 3) A triangular prism structured anti-hanging block is provided on one side of the blocking plate, and a counterweight block is provided on the other side of the blocking plate, and the weight of the counterweight block is greater than the weight of the anti-hanging block. After the blocking plate is flipped to the lower part of the U-shaped main frame, the counterweight block blocks the gap between the blocking plate and the side wall of the U-shaped main frame; due to the weight of the counterweight block, when the blocking plate is unlocked, the blocking plate automatically flips under the action of the counterweight block; after some of the wires slide out from the open side of the U-shaped main frame, they move downward along the blocking plate under the action of their own weight, and when they move to the end of the blocking plate, they move to the side away from the U-shaped main frame under the action of the anti-hanging block. The anti-hanging block cooperates with the counterweight block to reduce the possibility of the wires contacting and getting hung on the lower end of the U-shaped main frame, thereby avoiding equipment failure or safety hazards caused by wire hanging.

[0021] 4) A brush is installed at the bottom of the U-shaped main frame to remove foreign matter from the pulley wheels and avoid damage to the wires.

[0022] 5) By setting a lifting ring on the side of the lower part of the U-shaped main frame away from the blocking plate, and winding a pull rope on the lifting ring, after the blocking plate is opened, the operator pulls the pull rope on the ground to increase the inclination angle of the U-shaped main frame, so that the wire can slide out from the inside of the wire-laying pulley better.

[0023] 6) A torsion spring is provided in the middle of the hinge. In a natural state, the torsion spring causes the blocking plate to flip toward the lower part of the U-shaped main frame. When the blocking plate closes the opening of the U-shaped main frame, the torsion spring is in a stressed state. After the remote control lock unlocks the blocking plate, the blocking plate automatically flips under the action of the torsion spring.

[0024] 7) A height-adjustable protective component is provided inside the U-shaped main frame to prevent the conductor from being damaged by a rigid collision with the lower part of the top plate when the wire-laying pulley is in use.

[0025] 8) By setting a flip assembly, after the blocking plate is unlocked, the U-shaped main frame is flipped to one side of the top plate, further expanding the opening of the U-shaped main frame, which is conducive to the wires, especially large-diameter wires, to quickly slide out from the inside of the U-shaped main frame.

[0037] like Figure 1-4 As shown, the hanging groove 121 is a V-shaped structure, and one end of the hanging groove 121 is colinear with the center of gravity of the wire-paying pulley. When the wire is unrolled, the lower end of the hanger is hung at this end to ensure the stability of the wire-paying pulley; the other end of the hanging groove 121 deviates from the center of gravity of the wire-paying pulley and is away from the blocking plate 13.

[0042] like Figure 5 As shown, a torsion spring 191 is provided in the middle of the hinge 19. The torsion spring 191 causes the blocking plate 13 to flip toward the lower part of the U-shaped main frame 1 in a natural state. When the blocking plate 13 closes the opening of the U-shaped main frame 1, the torsion spring 191 is in a stressed state.
