Detailed ways

The present invention will be further explained below in conjunction with specific embodiments, but the present invention is not limited thereto.

Implementation: 1: As shown in Fig. 1 and Fig. 2, the present invention provides a pallet-type suspension bolt dismounting tool, including an insulating handle I1, a connecting fixture 3 and a supporting plate 6, and the connecting fixture 3 is covered with an insulating On the handle I1, it is used to connect the angle steel of the iron tower. The lower end of the insulating handle I1 is connected to the supporting plate shaft at one end of the supporting plate 6 to adjust the angle between the supporting plate 6 and the insulating handle I1. Fixtures.

The fixing device on the supporting plate 6 includes two parallel slide rails 5 arranged on the supporting plate 6, a groove-shaped cuboid slideway 8 is formed between the two parallel slide rails 5, and a groove-shaped cuboid slideway 8 is formed between the two parallel slide rails 4. The distance, i.e. the width of the cuboid slideway, is identical with the height of the nut of the bolt to be removed, so that the bolt to be removed is fixed by the cuboid slideway 8 and cannot rotate.

Several blocks of strong magnetic steel 5 are embedded in the corresponding slideway 8 positions in the supporting plate 6 to form a strong magnetic field to absorb the bolts to be disassembled and prevent the bolts from coming off and hurting people.

When the angle between the supporting plate 6 and the insulating handle I1 is 90 degrees, the overall side surface formed is L-shaped.

The lower end of the insulating handle I1 is connected to the supporting plate shaft. After the angle is adjusted between the supporting plate 6 and the insulating handle I1, it is fixedly connected by the fastener 7 to meet various angles of the suspended bolts to be dismantled. Fastener 7 of this example is a nut.

There are at least two fixing bolts on the connecting jig 3, which are respectively a first bolt 21 and a second bolt 22, wherein: the first bolt 21 is used to adjust the distance from the handle to the target bolt, and the second bolt 22 is used to fix the distance between the handle and the target bolt. The fixture is fixed with the iron tower angle steel.

When the present invention is in use, first adjust the position of the clamp 3, fix it by the first bolt 21, then connect the clamp 3 on the iron tower, and fix it by the second bolt 22, so that the supporting plate 6 is directly below the bolt to be disassembled , and the bolts to be dismantled are stuck in the slideway 8, and after the bolts to be dismantled are stuck, an insulating socket wrench can be used to complete the disassembly operation of the target bolts.

Embodiment 2: This example is different from Embodiment 1 in that: in order to make the present invention widely used, suitable for dismounting bolts of different types, a sliding device is provided between one of the two parallel slide rails 4 and the supporting plate 6, A movable slide rail 41 is formed to adjust the distance between two parallel slide rails.

As shown in Figure 3, the sliding device includes a lead screw, a screw nut, two parallel chutes and a sliding wheel. The two parallel chutes are arranged on the supporting plate 6, parallel to the moving direction of the slide rail, and the two ends of the movable slide rail are arranged At least two sliding wheels sliding along the chute, the lead screw is fixed on the supporting plate 6, the screw nut matched with it is fixed on the movable slide rail, the lead screw has a manual insulating handle II, and the manual insulating handle II is rotated to make Leading screw rotates, drives screw nut and upper movable slide rail to move along the chute on the supporting plate 6, realizes the purpose of fine-tuning the distance of two slide rails, and is conducive to fastening the bolt to be disassembled. When the two slide rails 4 form the maximum width, the sliding devices are placed under the movable slide rails and do not protrude into the slideway 8 .

The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Within the scope of knowledge of those of ordinary skill in the art, various modifications can be made without departing from the gist of the present invention. kind of change.
