Description

Tension block insulator replacement

technical field

The invention relates to an overhead tackle for replacing tension insulators.

Background technique

In the 330kV lines put into operation in Northwest China, porcelain insulators are used for tension strings, and double-string porcelain bottles are used for tension-resistant porcelain bottles. The design tension of the porcelain bottles is 21kN, the weight is 8-10kg, and the whole string of porcelain bottles is 176-220kg. To replace the whole string of insulators, because the whole string of porcelain bottles and replacement tools are too heavy, when installing tools and porcelain strings, due to the low lifting point of the circulating rope, it is very difficult for the staff to operate at high altitude, which virtually increases the danger of the workers.

At present, replacing the whole series of 330kV tension-resistant insulators with electricity is a very important item in the maintenance work of the line. The equipment is heavy, time-consuming and labor-intensive to install, it is very difficult for the staff to operate at high altitude, and the large physical energy consumption brings great safety risks to the operators.

Contents of the invention

The purpose of the present invention is to provide an overhead tackle for replacing tension insulators, which can raise the platform of the working face after use, thereby greatly reducing the physical energy consumption of operators.

An overhead block for replacing strain insulators, which is special in that it includes a manual block, a fixed plate and a movable plate are respectively installed on both sides of the top of the manual block, and an upper horizontal block passes through between the fixed plate and the movable plate. connecting rod, and the two ends of the upper horizontal connecting rod are respectively connected with the fixed plate and the movable plate; a channel steel is installed at the bottom of the hand block, and at least 2 fastening bolts are installed on the channel steel.

Wherein the fixed plate and the movable plate are arc-shaped plates.

Wherein the bottom end of the movable plate is hinged with the top of the manual tackle, and the movable plate is connected detachably with the upper horizontal link.

The detachable connection is specifically that a bayonet is installed on the movable plate, and a rotary lock that cooperates with the bayonet is installed on the upper horizontal connecting rod, so that the movable plate and the upper horizontal connecting rod can be fixed or loosened. open.

It has been proved by trials that the use of the sky block for replacing tension insulators of the present invention can effectively improve the platform of the working face, greatly reduce the physical energy consumption of operators, reduce the difficulty of work, and solve the problem of time-consuming and labor-intensive replacement of a whole string of porcelain bottles. The invention takes the hanging point of the raised circulating rope as a breakthrough, supports the overhead block through the connecting plate, and elevates the working surface, so as to reduce the working burden, shorten the working time, and reduce the beneficial effects of working safety risks. When in use, the pulley connected to the side connecting plate of the tension string conductor can be used to elevate the circulating rope and increase the lifting point of the uppermost circulating rope, which can significantly reduce the working intensity of live workers, reduce the difficulty of work, increase work efficiency and improve operation safety.

Detailed ways

As shown in Figures 1 and 2, the present invention is an upturned block for replacing tension insulators, including a manual block 4, which is basically composed of pulleys and a shell. A fixed plate and a movable plate 3 are respectively installed on both sides of the top of the manual tackle 4, and an upper cross-link 1 is passed between the fixed plate and the movable plate 3, and the two ends of the upper cross-link 1 are connected with the fixed plate respectively. Plate and movable plate 3 are connected. A channel steel 5 is installed at the bottom of the hand block 4, and two fastening bolts 6 are installed on the channel steel 5.

Wherein the fixed plate and the movable plate 3 are both arc-shaped plates, the bottom of the movable plate 3 is hinged with the top of the manual block 4, and the movable plate 3 is connected with the upper horizontal connecting rod 1 in a detachable manner, so as to facilitate the circulation rope to pass through . In addition, a bayonet socket is installed on the movable plate 3, and a rotary lock 2 matched with the bayonet socket is installed on the upper horizontal connecting rod 1, so that the movable plate 3 and the upper horizontal connecting rod 1 can be fixed or loosened. open.

The using method of the present invention is:

When in use, the present invention is connected to the side connecting plate of the strain-resistant series wire through the channel steel 5 and the fastening bolt 6, and the circulating rope is elevated to increase the lifting point of the uppermost circulating rope, thereby reducing the working intensity of the live workers and reducing the work load. Difficulty, increase work efficiency, improve operation safety.
