Problems solved by technology

At present, the specifications of high-voltage switch cabinets and circuit breaker trolleys in substations are not uniform
Moreover, due to the differences in breaking capacity, production year and corresponding main equipment, the circuit breaker trolleys have differences in wheelbase, volume, etc. During maintenance, multiple maintenance trolleys of different specifications are required to complete the maintenance work, which is extremely difficult. Greatly reduces work efficiency

Embodiment Construction

[0013] The multi-functional overhaul trolley of the present invention comprises a car body 1, and a wheel 8 is arranged at the bottom of the car body, with brakes on the wheels to ensure that the trolley stops stably. The car body 1 is provided with a liftable platform 7, and the platform 7 is connected with the top of the car body by four lifting screw rods 2, and the lifting of the platform 7 is realized by adjusting the lifting screw rods 2.

[0014] Four card slots 6 are arranged on the platform 7, which are divided into two groups, and the same group of card slots are arranged in parallel, and two limiting plates 4 are respectively embedded in two groups of card slots 6, and the limiting plates 4 can move in parallel in the card slots, The slot 6 is marked with a scale, which is convenient for determining the moving distance of the limiting plate 4 according to the scale. The top of the limiting plate 4 is provided with a handle 5, which can be hand-held when moving the l...

Abstract

The invention discloses a multi-functional overhaul trolley, which comprises a wheeled car body. The car body is provided with a platform that can be lifted and lowered. The platform is provided with four card slots, which are divided into two groups, and the same group of card slots are arranged in parallel. , the two limiting plates are respectively embedded in two groups of card slots, the limiting plates can move in parallel in the card slots, the card slots are marked with scales, and the limiting plates are provided with limiting sleeves. The invention can realize the operation function of the general circuit breaker maintenance trolley to switch the state of the handcart switch; it can be applied to various types of equipment, and is beneficial to the fixed management of the substation maintenance trolley, with low cost and high economic benefit.

Description

technical field [0001] The invention relates to a maintenance trolley for electrical equipment, in particular to a multifunctional maintenance trolley. Background technique [0002] High-voltage switchgear is one of the most commonly used equipment in substations. In order to ensure that the circuit breakers in the 10kV high-voltage switchgear are in good condition and the protection is reliable, regular inspections of switchgear or equipment maintenance after accident tripping are arranged every year. . When performing these types of operations, it is necessary to turn the trolley in the switch cabinet from the test state to the maintenance state, which requires the trolley to be pulled out or pushed in from the switch cabinet. At present, the specifications of the high-voltage switch cabinets and circuit breaker trolleys in the substation are not uniform. Moreover, due to the differences in breaking capacity, production year and corresponding main equipment, the circuit ...
