Description

A suspension mechanism in a lifting device

Technical field:

The utility model relates to a suspension mechanism in a lifting device.

Background technique:

When installing wires on the cross-arm of the utility pole, the construction personnel are often sent to the side of the utility pole by an insulated bucket arm truck, and then the construction personnel lift the wire and install it on the cross-arm of the utility pole. Due to live work, When the construction workers are hoisting the wires, a safety gap must be left between the construction workers and the wires. However, the safety gap of this construction method is difficult to be guaranteed, thus causing great safety hazards to the construction workers.

The cross-arms of utility poles include straight-line cross-arms, corner cross-arms and double cross-arms. Patent No. 201520555258.8 discloses a special lifter for 35kV and below multi-circuit mid-phase live work (as shown in Figure 1). The suspension in the lifter The structure can only be applied to double cross arms, and the applicability is small.

The rope reel 500 in the lifter disclosed in the above-mentioned patent is located under the installation frame 600 , and the installation frame is carried on the cross arm 400 . When hoisting electric wires, since the rope reel 500 is located under the mounting frame 600, the cross arm 400 will inevitably interfere with the rising of the electric wire during the hoisting process of the electric wire, so the electric wire can only be positioned under the cross arm all the time. Therefore, when the wire is hoisted to the bottom of the cross arm, it is necessary to use an insulating rod to pick the wire to the insulating rod first, then pass the insulating rod around the cross arm and place the wire on the upper end of the cross arm. The process is cumbersome, and the wires are easy to slip, which poses a great safety hazard.

Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art.

detailed description:

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 2 and 3, a suspension mechanism in a lifting device of the present invention includes a support frame 21, a splint 22, a fastening screw 23, a support rod 4 and an operating rod 5, and the two splints 22 are respectively inserted into the support The two sides of frame 21, and clamping cavity 20 is formed between splint 22 and support frame 21, fastening screw 23 is screwed on the support frame 21, and the bottom end of fastening screw 23 abuts on splint 22, and The splint 22 is fixed on the supporting frame 21 . Both the support rod 4 and the operating rod 5 are hinged on the lower end surface of the support frame 21 .

In the utility model, the two sides of the support frame 21 extend vertically downwards to form the first clamping wall 210, and the end of the splint 22 is bent vertically downwards to form the second clamping wall 220, between the first clamping wall 210 and the second clamping wall 220 The clamping cavity 20 is formed between them.

In order to increase the frictional force between the suspension mechanism of the present invention and the upper cross arm of the electric tower pole, bevel teeth are provided on the inner walls of the first clamping wall 210 and the second clamping wall 220 .

In order to prevent the lifting hook 13 from swinging along the axis of the take-up reel 11 during the lifting and lowering of the lifting rope 12 , a through hole 218 for passing the lifting rope 12 is provided at the center of the support frame 21 . The through hole 218 can effectively prevent the suspension hook 13 from swinging.

In order to be applicable to the wire tower rods of different pipe diameters, the support rod 4 in the utility model is a two-fold rod. In order to make it easier for the support rod 4 to abut against the wire tower rod better, a friction wheel 41 is provided at the bottom end of the support rod 4 .

Two supporting rods 4 and two operating rods 5 are provided, and the two supporting rods 4 are located between the two operating rods 5 . Two operation rods 5 are convenient to operate, and two support rods 4 increase the stability of the suspension mechanism of the present utility model. Operating rod 5 is a telescopic rod, which is suitable for cross bars of different heights.

In conjunction with Fig. 4, construction workers rise to the side of the utility pole to be operated through the insulated bucket arm truck, and the construction workers hang the suspension mechanism of the utility model on the cross arm of the electric tower pole through the operating rod 5 (this implementation process uses a straight line cross arm as the For example), by adjusting the size of the clamping cavity 20 to be suitable for cross-arms of different sizes, the friction wheel 41 at the bottom end of the support rod 4 abuts against the electric tower rod, and the stability is good.

When using the suspension mechanism of the present utility model, the take-up reel 11 is fixed on the top of the support frame 21, and the suspension hook 13 passes through the through hole 218 and extends to the lower end of the support frame 21. Since the wire take-up reel 11 is located above the cross arm of the electric tower pole, if the wire take-up reel 11 is in the process of hoisting the wire, if the cross bar interferes with the rise of the wire, it only needs to pull the wire with the help of an insulating rod to make the wire deviate from the cross bar. interference position, then the take-up reel 11 continues to hoist the electric wire and the electric wire is hoisted to the top of the cross bar. If the crossbar does not interfere with the rise of the electric wires, the wire take-up reel 11 can directly lift the electric wires to the top of the crossbar. Afterwards, the electric wire is picked out of the suspension hook 13 by means of the above-mentioned insulating rod body, so that the electric wire can be placed on the cross arm.

When the cross arm of the electric tower pole is a corner cross arm or a double cross arm, it is only necessary to place the lifting device of the present invention on one side of the corner cross arm or the double cross arm, and make the friction wheel 41 of the lifting device lean against On the wire tower pole, the hoisting of wires can be realized.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, some improvements can be made without departing from the principle of the utility model, and these improvements should also be regarded as the present invention. Protection scope of utility model.
