Description

Technical Field

[0001] The utility model relates to the technical field of anti-vibration hammers, in particular to a device for retrieving a line anti-vibration hammer after it slips. Background Art

[0002] The anti-vibration hammer is provided to reduce the vibration of the wire caused by the wind. The high-voltage overhead line poles are at a relatively high position and the span is relatively large. When the wire is affected by the wind, vibration will occur. When the wire vibrates, the working conditions at the wire suspension are the most unfavorable. Due to multiple vibrations, the wire will undergo fatigue damage due to periodic bending. When the span of the overhead line is greater than 120 meters, an anti-vibration hammer is generally used for anti-vibration.

[0003] The anti-vibration hammer operates on the vibrating line for a long time, which is likely to make the anti-vibration hammer loose and displaced. The displacement generally has the following adverse consequences: it cannot absorb energy to prevent the wire from vibrating; at an improper position, it will increase the vibration of the wire and accelerate the fatigue damage of the wire. If the anti-vibration hammer slides to the middle position of the line, the maintenance personnel need to climb to the position of the anti-vibration hammer through a hanging basket to restore the anti-vibration hammer. The whole process has the risk of falling. Therefore, at present, it is time-consuming and laborious to restore the anti-vibration hammer. Therefore, the utility model proposes a device for retrieving a line anti-vibration hammer after it slips. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a device for retrieving a line anti-vibration hammer after it slips.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A device for retrieving a line anti-vibration hammer after it slips, including a top plate. A chute is opened at the bottom of the top plate. A moving plate is slidably connected inside the chute. A screw rod for driving the moving plate to move up and down penetrates through the top of the chute. The screw rod is rotatably connected to the top wall of the chute through a bearing. Rollers are rotatably connected to the same side of the top plate and the moving plate. Impact components are installed on the sides of the top plate and the moving plate. The bottom end of the moving plate is fixedly connected with a traction component.

[0006] Further, a threaded groove is opened in the middle of the moving plate. The bottom end of the screw rod is located inside the threaded groove and is rotatably connected to the threaded groove. The top end of the screw rod is fixedly connected with a knob.

[0007] Further, a slider is fixed at the top end of the moving plate and away from the roller. A vertical strip-shaped opening is opened on the top plate close to the slider. The slider is located inside the strip-shaped opening and is slidably connected to the strip-shaped opening.

[0008] Further, a locking bolt penetrates through and is threadedly rotated at the bottom end of the top plate.

[0009] Further, a rubber sleeve is sleeved on the outer side wall of the roller.

[0010] Further, the impact assembly includes an L-shaped plate fixed to the sides of the top plate and the moving plate, and a plurality of rubber heads are fixed on the side of the L-shaped plate away from the roller.

[0011] Further, the traction assembly includes a bottom plate fixed to the bottom end of the moving plate. Two fixing rings are fixed on the lower surface of the bottom plate. A tripod is rotatably connected by the two fixing rings, and a traction rope is fixedly connected to the bottom end of the tripod.

[0012] Advantages of the present utility model:

[0013] When the present utility model is in use, for the device for retrieving the slip of a line shock absorber, a top plate, a moving plate, two rollers, a screw rod, an impact assembly and a traction assembly are provided. By rotating the screw rod, the moving plate can be driven to move in the chute at the bottom of the top plate, so as to adjust the two rollers to approach or move away from each other. When the two rollers approach each other, the two rollers can be clamped on the wire, and then the device is pulled along the wire by the traction assembly, and the shock absorber is impacted to the original position by the impact assembly. This device replaces manual climbing to remove the shock absorber and reinstall it, thereby avoiding the risk of falling caused by the line being unable to bear the weight during manual climbing of the line.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1-3 shown, it relates to a device for retrieving a line shock absorber after slippage, including a top plate 1. A chute 101 is opened at the bottom of the top plate 1. A moving plate 2 is slidably connected inside the chute 101. A screw rod 4 for driving the moving plate 2 to move up and down penetrates through the top of the chute 101. The screw rod 4 is rotatably connected to the top wall of the chute 101 through a bearing. Rollers 3 are rotatably connected to the same side of the top plate 1 and the moving plate 2. Impact components are installed on the sides of the top plate 1 and the moving plate 2. The bottom end of the moving plate 2 is fixedly connected with a traction component.

[0022] As Figures 1-3 shown, a threaded groove 21 is opened in the middle of the moving plate 2. The bottom end of the screw rod 4 is located inside the threaded groove 21 and is rotatably connected to the threaded groove 21. The top end of the screw rod 4 is fixedly connected with a knob 5.

[0023] Since the moving plate 2 can only slide up and down along the chute 101, when the screw rod 4 is rotated by the knob 5, the screw rod 4 will drive the moving plate 2 to move. After the moving plate 2 moves, the two rollers 3 will approach or move away from each other.

[0024] As Figures 1-2 shown, a slider 6 is fixed to the top end of the moving plate 2 and on the side away from the roller 3. A vertical strip-shaped opening 7 is opened on the side of the top plate 1 close to the slider 6. The slider 6 is located inside the strip-shaped opening 7 and is slidably connected to the strip-shaped opening 7.

[0025] By sliding the slider 6 in the strip-shaped opening 7, it can prevent the moving plate 2 from detaching from the chute 101, and under the guiding action of the slider 6, the moving plate 2 can move more stably inside the chute 101.

[0026] As Figures 1-2 shown, a locking bolt 8 is penetrated and threadedly rotated at the bottom end of the top plate 1.

[0027] After adjusting the position of the moving plate 2 inside the chute 101, the locking bolt 8 can be screwed to make the locking bolt 8 abut against the surface of the moving plate 2 to prevent the moving plate 2 from moving inside the chute 101 during the process of the device impacting the shock absorber.

[0028] As Figure 2 shown, a rubber sleeve 31 is sleeved on the outer side wall of the roller 3. When the two rollers 3 are stuck on the surface of the wire, the rubber sleeve 31 can protect the surface of the wire.

[0029] As Figure 1 and Figure 3 shown, the impact assembly includes an L-shaped plate 9 fixed to the sides of the top plate 1 and the moving plate 2, and a plurality of rubber heads 10 are fixed to the side of the L-shaped plate 9 away from the roller 3.

[0030] When the device moves along the wire, the shock absorber can be impacted by the rubber heads 10 to knock the shock absorber to its original position, and the rubber heads 10 can protect the shock absorber from being damaged.

[0031] As Figure 1 shown, the traction assembly includes a bottom plate 11 fixed to the bottom end of the moving plate 2. Two fixing rings 12 are fixed to the lower surface of the bottom plate 11. A tripod 13 is rotatably connected to the two fixing rings 12 together, and a traction rope 14 is fixedly connected to the bottom end of the tripod 13.

[0032] The tripod 13 can be pulled by the traction rope 14, and the device can be pulled along the wire by using the tripod 13. Since the tripod 13 can rotate along the fixing rings 12, the angle of the tripod 13 can be changed, and it is more labor-saving to pull the tripod 13 by the traction rope 14.

[0033] Working principle: After the maintenance personnel climb up the tower pole, place the two rollers 3 of the device above and below the wire respectively, then hold the top plate 1 and rotate the knob 5, drive the moving plate 2 to move along the chute 101 by using the screw rod 4, so that the two rollers 3 are stuck on the surface of the wire, and then tighten the locking bolt 8 to fix the moving plate 2, thus realizing the installation of the device. Then pull the device along the wire by the traction rope 14, and impact the shock absorber by the rubber heads 10 of the impact assembly to knock the shock absorber to its original position. When using this device to restore the shock absorber, there is no need to use a hanging basket and climb the wire, avoiding accidents caused by the wire being unable to bear the weight of the human body.
