Description

110kV line surge arrester hoisting frame

technical field

The invention relates to a hoisting tool, in particular to a hoisting frame of a 110kV line arrester.

Background technique

? During the construction of the lightning arrester replacement project, cranes and pick-up poles are usually used for hoisting tools. In order to prevent the crane from accidentally touching the operating equipment, power outages are required at adjacent intervals, which expands the scope of power outages; pick-up poles have high safety risks and require manpower and materials. There are many, and it is extremely inconvenient to assemble and install, and the fixation of the wave and wind rope is also close to the restriction of live equipment. The use of these two hoisting tools expands the scope of power outages, increases safety risks, and requires more manpower and materials. Therefore, it is necessary to provide a new technical solution to solve the above problems.

Contents of the invention

?? The purpose of the present invention is to provide a 110kV line lightning arrester hoisting structure that reduces the scope of power failure and improves the reliability of power supply.

The technical scheme adopted in the present invention is:

? 110kV line surge arrester hoisting frame, the hoisting frame includes a main pole, a ring pulley and a hoop, the lower part of the main pole is connected to two hoops through two fixed collars, and the two hoops are sleeved on the upper and lower pillars. An angle steel is installed on the top of the main pole, and a lifting ring pulley is installed on the angle steel. A wave and wind ring is also fixed on the top of the main pole. One end of the steel wire rope is inserted, and the steel wire rope passes through the wave wind ring, and a pulley is installed at the lower part of the pillar, and the other end of the steel wire rope passes through the pulley.

The shape of the ring pulley is U-shaped.

The advantages of the present invention are:

a. Improve the shortcomings of the previous equipment hoisting methods, reduce the scope of power outages, and reduce safety risks.

b. After using this tool, the labor intensity of construction personnel is reduced.

c. Improve work efficiency, reduce labor costs for the unit, and save expenses.

d. Reduce the scope of power outages and improve the reliability of power supply.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the hoisting frame of the 110kV line arrester of the present invention includes a main pole 3, a ring pulley 7 and a hoop 1, and the lower part of the main pole 3 is respectively connected with two hoops 1 through two fixed collars 2 , two hoops 1 are sleeved on the top and bottom of the pillar 9, an angle steel 6 is installed on the top of the main pole 3, and a lifting ring pulley 7 is installed on the angle steel 6, and a wave and wind ring 5 is also fixed on the top of the main pole 3, and the wave and wind ring 5 is fixed by holding Hoop 4 is fixed on the main rod 3, and wire rope 8 one end is penetrated in the suspension ring pulley 7, and wire rope 8 passes wave wind ring 5, and pulley 10 is installed on pillar 9 bottom, and wire rope 8 other ends penetrate this pulley 10.

According to the height of the equipment to be hoisted, the height of the hoisting frame can be adjusted by moving the hoop 1 at the lower part of the pillar 9, and the wire rope 8 is inserted into the upper ring pulley 7 to prevent the equipment from tilting or toppling when lifting the equipment, so that the equipment can be vertical For lifting up and down, a pulley 10 is installed at the bottom of the main pole 3 of the installed equipment, so that the steel wire rope 8 can pass through the pulley 10, and the personnel can pull the wire rope 8 upright when operating on the ground, which is easy to operate and ensures the smooth up and down of the lifting object.

Choose a suitable lifting position, set up the lifting equipment with 8 wire ropes, slowly pull the wire rope 8 to make the equipment reach the installation height, turn the frame to make the equipment above the main pole 3 and lower it slowly, and the equipment can be removed after installation Lifting frame. After using this tool, the labor intensity of construction personnel is reduced, the scope of power outage is reduced, and the reliability of power supply is improved.
