Description

A New Hoisting and Overturning Vehicle Used for Circuit Breakers

technical field

The utility model relates to a novel hoisting and overturning vehicle used for a circuit breaker.

Background technique

At present, the circuit breaker mainly adopts the following three technical solutions for flipping: (1) Install the protective bracket at the lower flange of the circuit breaker to flip the circuit breaker, that is, the corresponding type of protective bracket is fixed on the lower flange base with bolts, and the lower flange Tie the wind rope to the orchid; the hoisting and flipping operation is to use the contact point between the protective bracket and the ground as the fulcrum, and pull the wind rope firmly to prevent the fulcrum from moving. Retract and release the hook to turn the circuit breaker over; the whole process requires a total of 4 people, including wind rope pullers, circuit breaker turning assistants, crane operators, and crane operation commanders. This scheme is mainly used for on-site maintenance of circuit breakers. (2) Turn over the circuit breaker by double hooks of the crane or chain hoist, that is, use another chain hoist or a crane with an auxiliary hook to cooperate in the air, and pull the chain hoist or stretch the auxiliary hook to flip the circuit breaker The whole process requires a total of 4 circuit breaker flipping assistants, hand chain hoist personnel, crane operators, and crane operation command personnel. This scheme is mainly used for on-site maintenance of circuit breakers. (3) The electro-hydraulic forklift is used to overturn the circuit breaker in conjunction with the driving method, that is, one end of the circuit breaker is tied with a sling, and the end near the flange base is tied to the forklift fork arm. At the same time, the hook is lifted and lowered in conjunction with a series of actions such as driving forward and backward to turn the circuit breaker over; the whole process requires a total of 3 people, the driving operator, the hydraulic forklift operator, and the driving operation monitoring personnel. This scheme is mainly used for maintenance in the factory.

Deficiencies in prior art:

1. When the circuit breaker is hoisted and turned over on site, it is necessary to precisely control the extension and extension of the crane boom, the retraction and retraction of the hook, and the need to control the direction of the wind rope to ensure the smooth turning of the circuit breaker. Therefore, the operating skills of the lifting driver The level requirements are high. Improper cooperation of the driver or the operator can easily lead to problems such as slippage of the ground fulcrum, and there is a risk of damage to the equipment and injury to the operator.

2. When the circuit breaker is hoisted and flipped on site, due to the space limitation of the live equipment, lead wires and maintenance equipment in the substation, when the crane arm rotates at high altitude and expands greatly, the boom may touch the nearby live equipment and lead wires , bringing security risks.

3. When the circuit breaker is hoisted and flipped on site, it will take more manpower and time to install the protective bracket, pull the wind rope vigorously, and pull the chain hoist by hand.

4. When the circuit breaker is overhauled in the factory and the circuit breaker is hoisted and turned over, it is necessary to closely cooperate and coordinate the operation of the driving operator and the hydraulic forklift operator to ensure the smooth turning of the circuit breaker. This method requires a high level of operating experience for the operator. People are difficult to complete.

5. When the circuit breaker is overhauled in the factory and the circuit breaker is hoisted and flipped, the electro-hydraulic forklift used needs to perform battery charging, hydraulic system inspection and maintenance, etc., and the hydraulic forklift is relatively heavy and manpower will consume a lot of physical strength.

6. When the circuit breaker is overhauled in the factory and the circuit breaker is hoisted and flipped, it is necessary to tie the circuit breaker to the forklift fork arm with a sling. During this period, there is a risk of collision damage between the porcelain bottle and the iron fork.

(2) Fix the circuit breaker flange on the universal quick-loading bracket of the utility model. Using the bracket is safer and more convenient than using the wind rope and the hanging rope, and compared with the existing technology, the required number of operators can be reduced. 1 person, the working time can be shortened by 50%. (3) The bracket of the utility model is made of aluminum alloy material, which is light in weight and easy to transport and carry, and adopts a pyramid-shaped bracket with pulley design, which is safe and stable when used, and has a simple structure and minimal maintenance workload. (4) The utility model and the lower flange of the circuit breaker are fixed firmly through the bracket, and move along with the circuit breaker during use, without colliding with each other and causing damage to the porcelain bottle. (5) The utility model adopts an adjustable lifting shaft and a universal quick-installation bracket, which can be adapted to various circuit breakers and transport trolleys, and can be directly used as a complete set, and the circuit breaker can be firmly fixed to the utility model without changing tooling.
