Description

Transmission line lifting point fixture

Technical field:

The utility model relates to a jig, in particular to a jig which is applied in a power transmission line and can more scientifically provide lifting points for hoists and other facilities.

Background technique:

The hoist is a very commonly used tool when erecting or overhauling the transmission line. For example, when tensioning the transmission line on the cross arm of the tower, the transmission line can pass through the fixed pulley on the hoist, and the staff can Standing on the ground and pulling the transmission line can complete the line tightening work. When replacing the porcelain bottle and insulator on the cross arm, the porcelain bottle or insulator can be transported to the cross arm through the fixed pulley on the hoist. There is no lifting point for hanging the gourd on the cross arm, and only a rope sleeve can be set on the cross arm as the hanging point. There is still a considerable distance between the fixed pulley and the crossarm, so that appliances such as porcelain bottles and insulators cannot be transported in place, resulting in the work not being completed smoothly, resulting in low work efficiency and high labor intensity for operators; moreover, Using the rope sleeve as the hanging point has poor stability and poor accuracy, and the construction quality is difficult to guarantee.

Utility model content:

In order to overcome the defects of the prior art, the purpose of this utility model is to provide a suspension point clamp for transmission lines, which can increase the vertical height and horizontal span of the suspension point, and the stability of the suspension point is good, and the accuracy of the suspension line is high.

The utility model solves the technical problem and adopts the following technical solutions:

Transmission line lifting point fixture, the fixture is composed of a vertical pole that can be fixedly connected with the cross arm of the tower and a cantilever fixedly connected to the upper end of the vertical pole, and the other end of the cantilever is provided with a ring for hanging by a hook.

Structural features of the present utility model also are:

The vertical rod is a relatively rotatable two-stage structure, the top of the lower vertical rod is provided with a first threaded rod extending longitudinally upwards, the upper vertical rod is sleeved on the first threaded rod, and the top of the first threaded rod There are nuts that can fix the upper pole.

A second threaded rod extending longitudinally downward and a third threaded rod extending horizontally are fixed on the lower vertical rod, and rotatable tile-type fasteners are respectively pierced on the second and third threaded rods , and the second and third threaded rods are respectively provided with wing nuts that can clamp the fasteners on the cross arms of the tower respectively.

Compared with the prior art, the beneficial effects of the utility model are reflected in:

1. The lifting point fixture of the utility model is composed of a vertical rod that can be fixedly connected with the cross arm and a cantilever fixedly connected to the upper end of the vertical rod. When the vertical rod is fixed on the cross arm, the height of the cantilever is higher than that of the cross arm Therefore, when the hook of the hoist is hung on the ring on the cantilever, the fixed pulley of the hoist is above the cross arm, which can conveniently transport porcelain bottles, insulators and other appliances to the cross arm, and the hanging point has high stability.

2. The vertical rod of the utility model is a two-stage structure that can rotate relatively. By adjusting the tightness of the nut on the first threaded rod, the upper vertical rod can be fixed on the lower vertical rod, and the upper vertical rod can be fixed relative to the lower vertical rod. The lower vertical rod is rotated to adjust the horizontal span of the lifting point on the cross arm, which can conveniently transport porcelain bottles, insulators and other appliances to the desired position.

3. In the utility model, the second and third threaded rods perpendicular to each other are fixed on the lower vertical rod, and tile-type fasteners are respectively pierced on the two threaded rods, and the tiles can be fixed with butterfly nuts. The sheet-type fasteners are respectively clamped on the cross-arm angle steel. This structure is convenient for installation and disassembly, and can firmly fasten the pole on the cross-arm angle steel to improve the stability of the lifting point.

4. The tile-shaped fasteners of the utility model can be made by cutting from the middle with a C32-type screw cap, and the vertical pole can be made with a C24-type turnbuckle bolt, so that waste can be reused and the cost is low.

The utility model will be further described below through specific embodiments in conjunction with the accompanying drawings.

Detailed ways:

Embodiment: Referring to Figures 1 and 2, the power transmission line suspension point fixture of this embodiment is composed of a vertical pole 1 that can be fixedly connected with the cross arm of the tower and a cantilever 2 that is fixedly connected to the upper end of the vertical pole. The other end of the cantilever is set There is a suspension ring 3 for hook suspension, and the vertical rod is a two-stage structure that can rotate relatively, including an upper vertical rod 1-1 and a lower vertical rod 1-2, and the top of the lower vertical rod is provided with a first threaded rod extending longitudinally upwards 4-1, the upper vertical rod is sleeved on the first threaded rod, and the top of the first threaded rod is provided with a nut 5 that can fix the upper vertical rod.

In order to fix the vertical rod on the pole tower cross arm 6 (angle steel), a second threaded rod 4-2 extending longitudinally downward and a third threaded rod extending horizontally are fixed on the lower vertical rod 1-2. 4-3, the second and third threaded rods are respectively pierced with rotatable tile-type fasteners 7, and the second and third threaded rods are respectively provided with Wing nut 8 on the pole tower cross arm.

During specific implementation, as shown in Figure 2, rotate the fasteners 7 and adjust the angles respectively, clamp them on the two side edges of the cross arm 6, tighten the wing nuts 8 respectively, and then the vertical rod can be fixed on the cross arm , when in use, the hook of the hoist 9 is hung on the suspension ring 3 of the cantilever 2. At this time, the fixed pulley of the hoist is above the cross arm, so the power transmission equipment such as porcelain bottles, insulators, and wires can be easily suspended by cables. It is more convenient, faster and more stable to be placed on the cross arm, which improves the work efficiency and reduces the labor intensity of the workers. In addition, the level of the lifting point of the lifting ring on the cross arm can also be adjusted, and has a large horizontal span. When it is necessary to fix the upper tie rod 1-1 on the lower vertical rod 1-2, tighten the nut 5 on the first threaded rod 4 It can be realized that when the horizontal position of the lifting point needs to be adjusted, the nut 4 is loosened, and the upper vertical rod 1-1 is rotated until the desired position is reached, and then fixed with a nut.
