Description
Technical field
The utility model relates to a kind of electricity check trolley with valve self-locking device intermediate switchgear cabinet.
Background technology
Intermediate switchgear cabinet, full name is metal armouring middle disposed withdrawn type switchgear, belongs to high voltage distribution installation, maximum operating voltage 3.6/7.2/12/24kV, is the indoor complete power distribution equipment of three-phase alternating current 50Hz single busbar system or sectionalized single busbar connection system.For accepting and distribute the network power of 3.6-12kV, and Control protection, monitoring and measuring are carried out to power circuit.Intermediate switchgear cabinet is mainly used in power plant, the power transmission of medium and small generator, powered, the power transmission of electric power system secondary substation, the distribution of industrial and mineral enterprises and institutions, and the starting etc. of Large-scale High-Pressure motor.The intermediate switchgear cabinet of current production, during power failure, as carried out electrical verification operation, can only manually raise valve baffle plate, and then electrical verification.But with high-tension electricity in intermediate switchgear cabinet, as charged position is touched in operating process accidentally, then serious personal injury can be caused.Part power station requires that intermediate switchgear cabinet increases valve self-locking device, self-locking device 7 as shown in Figure 5, comprise snap close 71 and shank of the key 72 two positions, help as there is no aid, can only pass through manual release, hand must be put into inside breaker chamber and be pushed open by snap close and could unlock by operating personnel, and needs two people to coordinate just to open valve baffle plate, so greatly increase operation easier, and easily occur the danger of touching high-tension electricity.
Utility model content
Technical problem to be solved in the utility model, is just to provide a kind of electricity check trolley with valve self-locking device intermediate switchgear cabinet, and valve self-locking device can be driven to move, and valve self-locking is unlocked, opens valve baffle plate, facilitates user to carry out electrical verification.
Solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of electricity check trolley with valve self-locking device intermediate switchgear cabinet, it is characterized in that: comprise a flat vehicle frame, flat bottom of frame is provided with roller, anterior the right and left of flat vehicle frame is provided with biside plate, the outside of biside plate is respectively equipped with the pressing plate with two horizontal sides, the horizontal sides front portion of described pressing plate is upwards opposing and curve crotch downwards.
Improve as one of the present utility model, described pressing plate is open horizontal U-shaped plate outwardly, and described U-shaped plate two parallel edges front portion is upwards opposing and curve crotch downwards.
Improve as another kind of the present utility model, described pressing plate is about the two pieces level boards placed, and described level board front portion is upwards opposing and curve crotch downwards.
The junction of described crotch and horizontal sides is that circular arc is smoothly connected.
Compared with prior art, the utility model instrument has the following advantages:
The utility model provides a kind of electricity check trolley with valve self-locking device intermediate switchgear cabinet, electricity check trolley is utilized to be opened by valve self-locking device and without operating personnel's manual unlocking, make intermediate switchgear cabinet electrical verification convenient, and can operator safety be ensured, reduce operation easier.

Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
The electricity check trolley of band valve self-locking device intermediate switchgear cabinet is as shown in Figure 1, 2 one of embodiment of the present utility model, it comprises a flat vehicle frame 1, flat bottom of frame is provided with roller 2, anterior the right and left of flat vehicle frame is provided with the biside plate 3 of setting, the outside of biside plate is respectively equipped with open horizontal U-shaped plate 4 outwardly, wherein U-shaped plate two parallel edges front end is upwards opposing and curve crotch 5 downwards, and the junction of crotch and parallel edges is that circular arc is smoothly connected.
As shown in Fig. 5,6,7, electricity check trolley is when work, electricity check trolley moves by circuit breaker crank by operating personnel from left to right, in advance process, the snap close of self-locking device is pushed open by the junction of crotch of the present utility model and parallel edges at first, thus the shank of the key 72 of self-locking device 7 is unlocked from snap close 71, electricity check trolley continues to move right, until valve is opened, after valve is opened, because crotch can block shank of the key, valve can not be resetted, thus play position-limiting action, operating personnel can carry out electrical verification operation.
The electricity check trolley of band valve self-locking device intermediate switchgear cabinet is as shown in Figure 3,4 embodiment two of the present utility model, it comprises a flat vehicle frame 1, flat bottom of frame is provided with roller 2, anterior the right and left of flat vehicle frame is provided with the biside plate 3 of setting, the outside of biside plate is respectively equipped with about the two pieces level boards placed 6, two pieces of level board front ends are upwards opposing and curve crotch 5 downwards, and the junction of crotch and level board is that circular arc is smoothly connected.The present embodiment is identical with the using method of one of embodiment.
