Abstract

The utility model discloses a tension cross arm hoisting device which settles the following defects in hoisting the prior tension cross arm: time wasting, labor wasting, and certain safety hazard. The tension cross arm hosting device comprises a power transmission line pole (1) and a pi-shaped portal frame (4). The pi-shaped portal frame (4) is internally provided with two horizontal supporting bolts (5). The bottom end of the pi-shaped portal frame (4) is fixedly connected with a hoop iron (6) which is clamped on the power transmission line pole (1). The two horizontal supporting bolts (5) are lapped on the top end of the power transmission line pole (1). A fixed pulley fixing cantilever beam (11) is fixedly arranged at the right end of the pi-shaped portal frame (4). The fixed pulley fixing cantilever beam (11) is provided with a fixed pulley (7) on which a hoisting rope (8) is arranged. According to the tension cross arm hoisting device, the tension cross arm can be assembled on the power transmission line pole by one person, thereby greatly enlarging safety factor and shortening working time.

Description

Tension cross arm hoist

technical field

The invention relates to a hoist, in particular to a hoist for assembling a tension cross arm on a power transmission tower.

Background technique

When erecting transmission lines, it is necessary to assemble the tension cross arms on the transmission poles. One way is that two operators climb up the transmission poles at the same time. After the mutual alignment of the upper and lower arms is completed, the bolts are fixed; the other method is that the ground staff perform preliminary assembly on the tension cross arm on the ground, tighten the threaded screws properly, and two people on the pole jointly lift it, and then the Two people forcefully lift it up, and after passing through the top of the transmission line pole, two people lift the end level at an appropriate position, and tighten the screws to fix the tension cross arm. These two methods must be completed by the cooperation of two staff members on the pole. Two people operate the same pole at the same time. Because the working space on the pole is limited, it is time-consuming and laborious and has certain potential safety hazards.

Contents of the invention

The invention provides a tension cross-arm hoist, which solves the problems of time-consuming and labor-intensive hoisting of the existing tension cross-arm and certain potential safety hazards.

The present invention solves the above technical problems through the following technical solutions:

A tension-resistant cross-arm hoist, including a power transmission pole and a π-shaped gantry, two horizontal support bolts are arranged in the π-shaped gantry, and a hoop is fixedly connected to the bottom of the π-shaped gantry, and the hoop is clamped Connected to the power transmission pole, two horizontal support bolts are lapped on the top of the power transmission pole, a fixed pulley is fixed on the right end of the π-shaped gantry, and a fixed pulley is fixed on the fixed pulley. A sling is arranged on the fixed pulley, and one end of the sling is connected with a tension cross arm, and the other end of the sling is pulled by the ground staff.

A hanging hole is arranged at the left end of the π-shaped gantry, and a pulley hook is arranged in the hanging hole.

The invention only needs one person to assemble the tension cross arm on the power transmission pole, which greatly reduces the labor intensity, greatly improves the safety factor and shortens the working time.

Detailed ways

A tension-resistant cross-arm hoist, comprising a power transmission pole 1 and a π-shaped gantry 4, two horizontal support bolts 5 are arranged inside the π-shaped gantry 4, and a holding bolt is fixedly connected to the bottom end of the π-shaped gantry 4. The hoop 6, the hoop 6 is clamped on the transmission line pole 1, and the two horizontal support bolts 5 are overlapped on the top of the transmission line pole 1, and the fixed pulley fixed pick beam 11 is fixedly arranged on the right end of the π-shaped gantry 4. A fixed pulley 7 is arranged on the fixed pulley beam 11, and a sling 8 is arranged on the fixed pulley 7. One end of the sling 8 is connected with a tension cross arm 9, and the other end of the sling 8 is used by the ground staff 10. pulling.

The left end at π font gantry 4 is provided with hoisting hole 3, is provided with pulley hook 2 in hoisting hole 3, also can hang and connect fixed pulley and carry out hoisting operation on pulley hook 2.
