Description

Power grid maintenance self-balancing insulating spreader

technical field

The utility model relates to a self-balancing insulating hanger for power grid maintenance, which belongs to the maintenance equipment of substations.

Background technique

With the rapid development of the power grid, people's demand for electricity is getting higher and higher, and the reliability of power supply is also getting higher and higher. In order to ensure the reliability of power supply, it is necessary to overhaul the equipment, and an equipment overhaul often requires the use of large equipment, such as cranes. However, due to the long construction time of some substations, the complex structure of substations, and the increasingly strict requirements of power supply companies for power supply reliability, the scope of power outages is also strictly controlled for maintenance work. For example, the main and auxiliary buses cannot be powered off at the same time , so that some maintenance work, such as the replacement of the switch knife, cannot be carried out by a crane due to the insufficient safety distance, and can only be installed by manpower or by a pole. However, these methods are not very convenient, time-consuming and laborious, and cannot satisfy maintenance requirements.

Contents of the invention

The technical problem to be solved by the utility model is to provide a power grid maintenance self-balancing insulating hoist which is not only convenient to use, safe and reliable, but also can improve work efficiency and save labor time.

In order to solve the above-mentioned technical problems, the power grid maintenance self-balancing insulating hoist of the present utility model includes a disc base, a winch, a motor, a boom, a support rod and a pulley. The base is provided with a rectangular support seat, and the rear of the rectangular support seat is equipped with a motor and a hoist; the rectangular support seat is provided with an insulating boom protruding forward and upward, and a pulley is installed on the top of the insulating boom, and the insulating pull rope drawn from the hoist The pulley on the top of the insulating boom is connected to the hook, and the motor drives the hoist to make the pull rope on the hoist stretch and move; the front end of the rectangular support seat is provided with a support frame for supporting the boom, and the rear end is provided with an operating handrail. The armrest can make the disc rotate 360 degrees around the axis; the rear end of the rectangular support seat is provided with an adjustment platform, which can place a counterweight pressing block.

A circular track is arranged on the edge of the base of the disc, and the rectangular support seat is seated on the circular track through the rollers at the bottom.

There is a telescopic structure between the adjustment stand and the rectangular support seat.

The counterweight briquetting block is formed by pouring cement, and the edges of the briquetting block are wrapped with angle steel.

After adopting such a structure, since the boom is made of insulating material as a whole, it prevents the electric shock caused by the boom hitting the power grid during use, and at the same time, because the disc rotates 360 degrees around the axis, one person can carry out the operation. The operation can realize 360-degree rotation, which makes it easy to use. It is suitable for the area where the working space is narrow and the crane is not easy to work. It greatly reduces labor intensity, reduces working hours, reduces power outage time, and improves power supply reliability; The structure can be made more compact by setting the telescopic adjustment stand; after the mobile adjustment stand is pulled out, different numbers of counterweight briquetting blocks can be placed according to the gravity of the hoisted object to achieve the purpose of adjusting the balance of the crane.

Detailed ways

As shown in the figure, the power grid maintenance self-balancing insulating hoist of the present invention includes a disc base, a hoist, a motor, a boom, a support rod and a pulley. A rectangular support base 3 is provided on the pan base 1, and a motor 11 and a hoist 10 are provided at the rear of the rectangular support base; an insulating boom 5 protruding forward and upward is provided on the rectangular support base 3, and a pulley 13 is installed on the top of the insulating boom , the insulating stay rope 14 drawn out by the winch is connected to the hook 12 around the pulley at the top of the insulating boom, and the motor 11 drives the winch 10 to make the insulating stay rope extend and move; the front end of the rectangular support base 3 is provided with a supporting insulating hanger The support frame 6 of the arm 5 is provided with an operating armrest 7 at the rear end, and the disc can be rotated 360 degrees around the axis through the operating armrest 7; the rear end of the rectangular support seat 3 is provided with an adjustment stand that can be freely pulled in and out 8; Place the counterweight briquetting block 9 on the adjustment platform 8 . Counterweight briquetting 9 is formed by pouring cement, and briquetting limit is wrapped with angle steel, also can adopt other weight simultaneously as the counterweight briquetting of balance crane.

After the mobile adjustment platform 8 is pulled out, different numbers of counterweight briquetting blocks 9 can be placed on the mobile adjustment platform 8 according to the gravity of the hoisted objects, so as to achieve the purpose of adjusting the balance of the crane.

The edge of the disk base 1 is provided with a circular track, and the rectangular support seat is seated on the circular track through the rollers at its bottom to guide its rotation.

When operating and using, set up a full-time guardian who is responsible for monitoring the whole process of lifting. Before use, the weight of the object to be hoisted should be estimated, and the adjustment platform 8 should be pulled out and the counterweight block 9 should be placed to adjust the balance of the crane. Then start the motor to drive the winch to run. The pull rope is free to expand and contract according to the usage under the action of the winch. When it is necessary to adjust the angle of lifting heavy objects, the angle can be made in real time by rotating the handrail. Adjustment, the insulating material used in the lifting arm can prevent dangerous situations caused by the lifting arm touching the net and dropping the net during the lifting process.
