Description

Technical Field

[0001] The invention relates to the technical field of electric power repair, and in particular to a conductor lifting device for an electric power repair tower. Background Art

[0002] Power repair is an emergency operation to restore power supply as soon as possible after a power facility fails. When the connection between the wire and the tower is broken and falls to the ground, technicians need to lift the wire back to the top and install and connect it in time to reduce the economic losses and impact on life caused by circuit damage.

[0003] The patent document with publication number CN116960825A discloses a hand-cranked rotary conductor lifter, comprising a sleeve, a lifting rod arranged in the sleeve and lifted and lowered in the sleeve, a hook mechanism for hooking the cable is provided at the upper end of the lifting rod, and a clamping mechanism for clamping the pole and a connecting mechanism connected to the crossbar are provided on the sleeve; during power maintenance, the sleeve is fixed to the pole by the clamping mechanism, and connected to the crossarm by the connecting mechanism to fix the sleeve to the pole, and then the lifting rod rises, the hook mechanism hooks the cable, and lifts the cable, so that the conductor is raised to a safe distance of 0.4m away from the personnel, so that the live working personnel can carry out live maintenance work on the pole tower equipment.

[0004] When the prior art is used to lift and repair a broken wire, the lifting equipment is usually fixed on the power tower column, and the broken wire is lifted upward by a hook. When the two ends of the wire are in a tensioned state and are respectively fixed on the tops of two power towers, when one end of the wire breaks and falls to the ground, the two ends of the wire are respectively located on the ground and on the top of another power tower. When the staff on the ground pulls the broken end of the wire to the bottom of the corresponding power tower top, the two ends of the wire are respectively located at a high place and on the ground and are in an inclined state, resulting in the broken end of the wire being unable to contact the corresponding power tower in the inclined state. Due to the vertical lifting, there is a certain horizontal distance between the broken end of the wire and the top of the power tower.

[0017] 2. The limit plate rotates synchronously through the sliding limit of the bar groove and the rotating rail, thereby driving the rotating shaft to rotate inside the slider, so that the connecting bar flips upward with the rotation of the rotating shaft, and stops rotating after the rotating shaft rotates ninety degrees, completing the flipping of the connecting bar, so that the wire is lifted upward during the flipping process of the connecting bar and approaches the top of the power tower, making it easier for repair personnel to re-fix the wire end on the top of the power tower.

[0018] 3. The movable block moves along the sliding joint of the circular rod and squeezes the spring to produce compression deformation.

[0019] 4. The limit pin moves synchronously during the flipping of the movable bar and approaches the corresponding arc groove on one side of the positioning bar, thereby limiting the positioning bar through the arc groove, thereby limiting the telescopic movement between the connecting bar and the movable bar, so that when the repair personnel fix one end of the wire on the top of the power tower, the connecting bar and the movable bar remain stable and prevent the fixing plate from moving, thereby improving the stability of the wire during the repair process.

[0020] 5. The maintenance personnel can pull one end of the wire toward the top of the power tower to fix one end of the wire on the top of the power tower. When one end of the wire moves, the clamping wheels on both sides rotate towards each other through contact friction. When one end of the wire moves in the opposite direction, the elastic stopper locks the ratchet to limit the reversal of the clamping wheel, thereby preventing one end of the wire from escaping from between the two clamping wheels, ensuring the firmness of the clamping while improving the convenience of installation and fixation for the staff.

DETAILED DESCRIPTION

[0034] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0035] like Figures 1 to 12 The wire lifting device for power repair tower shown in the figure comprises a support shell 1, one end of the support shell 1 is fixedly connected to a mounting frame 2, and two groups of fixing components are arranged on the side of the mounting frame 2 away from the support shell 1, and the fixing components include two arc-shaped positioning claws 3, and a movable positioning mechanism is connected between the two arc-shaped positioning claws 3 in the same group;

[0036] Connecting bars 4 are provided at the bottom of both sides of the support shell 1, and movable bars 5 are provided at one end of the connecting bars 4. A fixing plate 6 is provided between the two movable bars 5, and a wire clamping mechanism is connected to the fixing plate 6. A vertical rising mechanism and a flip lifting mechanism are connected to the two connecting bars 4. A movable telescopic mechanism is connected between the connecting bars 4 and the corresponding movable bars 5. A climbing frame 7 is fixedly connected to the side of the support shell 1 away from the mounting frame 2, and the climbing frame 7 is located between the two connecting bars 4. When working, the prior art usually fixes the lifting equipment on the power tower column when lifting and repairing the broken wire, and lifts the broken wire upward by hooking. When the two ends of the wire are in a tensioned state and are respectively fixed on the two ends, When a worker is on the top of a power tower, one end of the wire breaks and falls to the ground, and the two ends of the wire are respectively located on the ground and on the top of another power tower. When the worker is on the ground pulling the broken end of the wire to the bottom of the corresponding power tower, the two ends of the wire are respectively located at a high place and on the ground and are in an inclined state, resulting in the broken end of the wire being unable to contact the corresponding power tower in the inclined state. A certain horizontal distance exists between the broken end of the wire and the top of the power tower due to vertical lifting. The repair workers at a high place still need to move the broken end of the wire horizontally to the original top of the power tower, thereby affecting the repair efficiency of the repair workers and increasing the risk of high-altitude wire pulling. The present technical solution can solve the above problems and has The working method of the body is as follows: two sets of arc-shaped positioning claws 3 are fixedly sleeved on the power tower through the action of the mobile positioning mechanism, so that the support shell 1 maintains the limit in the vertical direction and is supported on the ground by the bottom end of the support shell 1. When one end of the wire falls to the ground and is at a certain distance from the power tower, through the length of the movable bar 5 and the connecting bar 4 themselves and the action of the movable telescopic mechanism, the fixed plate 6 can contact the end of the broken wire and be positioned on the fixed plate 6 through the wire clamping mechanism. Then, the two connecting bars 4 are vertically raised through the action of the vertical rising mechanism, and the movable bar 5 and the fixed plate 6 are driven to rise, so that one end of the wire is lifted. After rising to the corresponding height, the wire is lifted by turning the movable bar 5 and the fixed plate 6. The function of the rotating and lifting mechanism is to flip the connecting bar 4 along one end close to the supporting shell 1, and drive the movable bar 5 and the fixed plate 6 to move synchronously, so that the fixed plate 6 is flipped to the top of the climbing frame 7, and one end of the broken wire is flipped and lifted to the top of the power tower. The staff climbs to the top of the supporting shell 1 through the climbing frame 7, so as to approach the top of the power tower and install the wiring of the lifted wire. Through the vertical rise of the fixed plate 6 and the subsequent flipping movement, one end of the wire is lifted to the height before the fracture, and at the same time, it is close to the top of the power tower by using the flipping of the fixed plate 6, so as to facilitate the repair personnel to install the wiring and improve the repair efficiency, and reduce the work risks caused by the repair personnel pulling the wire at high altitude.

The two connecting plates 8 are symmetrically threadedly connected to both ends of the first bidirectional lead screw 10. A first motor 11 is fixedly installed on the mounting frame 2, and the output shaft of the first motor 11 is fixedly connected to one end of the first bidirectional lead screw 10. When working, the corresponding two arc-shaped positioning claws 3 are The positioning claws 3 approach the direction of the power tower and make the power tower be located between the two arc-shaped positioning claws 3. The output shaft of the first motor 11 rotates to drive the first bidirectional lead screw 10 to rotate unidirectionally. The threaded connection between the first bidirectional lead screw 10 and the two connecting plates 8 makes the two connecting plates 8 approach each other along the sliding connection of the light rod 9, and drives the two arc-shaped positioning claws 3 to approach each other, so that the two arc-shaped positioning claws 3 clamp and limit the power tower. Through the clamping and limiting of the two groups of arc-shaped positioning claws 3, the support shell 1 is vertically limited on one side of the power tower, thereby ensuring the stability of the wire during lifting and the safety of the repair personnel when climbing with the climbing ladder.

The connecting bar 4 always remains horizontal when it rises vertically. When the slider 12 moves to the top of the sliding groove 13, the strip groove 21 on the limit plate 19 moves from the contact end of the limit rail 20 and the rotating rail 24 to the rotating rail 24, and is slidably connected with the rotating rail 24 and the strip groove 21. Then, the rotating rail 24 is driven to rotate by the rotation of the piston shaft of the swing cylinder 23. The limit plate 19 rotates synchronously through the sliding limit of the strip groove 21 and the rotating rail 24, thereby driving the rotating shaft 14 to rotate inside the slider 12, so that the connecting bar 4 flips upward with the rotation of the rotating shaft 14, and stops rotating after the rotating shaft 14 rotates ninety degrees, completing the flipping of the connecting bar 4, so that the wire is lifted upward during the flipping process of the connecting bar 4, and approaches the top of the power tower, so that the repair personnel can re-fix the wire end to the top of the power tower.

When the movable bar 5 moves, the movable block 26 moves along the sliding connection of the round rod 27 and squeezes the spring 28 to produce compression deformation. When the connecting bar 4 and the movable bar 5 rise vertically and drive one end of the wire to rise, as the height of one end of the wire gradually rises and approaches the height of the other end, one end of the wire gradually approaches the top of the power tower, so that under the elastic stretching action of the spring 28, the movable bar 5 gradually returns to the initial position, and at the same time, one end of the wire is pulled toward the top of the power tower to be installed.
