Description
Technical field:
The utility model relates to a kind of mechanical door opener of switch casing, particularly a kind of quick-opening device of flame-proof type switch casing.
Background technology
At present, the flameproof high-voltage switch-box of colliery down-hole application mostly adopts bolt compression type quick operating valve or rack-and-pinion quick operating valve form, and low tension switch generally adopts the quick operating valve mode of side-to-side movement.The bolt compression type speed of opening the door is slow, also cumbersome; Rack-and-pinion quick operating valve mode, though mode of operation is fairly simple, the bad control of its flameproof gap has taken cavity space, has reduced the cavity space utilance; And the quick operating valve mode of side-to-side movement generally is not suitable for high-voltage switch gear, because the door of high-voltage switch gear is bigger, also heavier, and easy deformation.
Summary of the invention
The utility model has solved the down-hole high pressure switch-box and has embodied and to have the equipment slow and rack-and-pinion quick operating valve mode of speed of opening the door not to be suitable for high-voltage switch gear, and has taken the casing cavity space, has reduced the technical problem of cavity space utilance.
The utility model is to solve above technical problem by the following technical programs:
The explosion-proof switch quick-opening device, comprise explosion-proof switch casing, door body 2, the top board 4 of fixedlying connected, upper supporting plate 8 and lower carrier plate 11 with casing, the last connecting lever 5 and the following connecting lever 12 of fixedlying connected with door body 2, be set with elevating lever 9 between last connecting lever 5 and the following connecting lever 12, and elevating lever 9 can slide up and down in the pilot hole of upper supporting plate 8 and lower carrier plate 11, between described top board 4 and upper supporting plate 8, be provided with eccentric wheel 13, this eccentric wheel 13 is fixed together with last connecting lever 5, and an end is set with handle 10; Be set with grab 3 in the upper end of door body 2, be set with grab 1 in the both sides of door body 2; When upwards lifting handle 10, eccentric wheel 13 slides on upper supporting plate 8, and connecting lever 5, elevating lever 9, door body 2 and following connecting lever 12 move up thereby drive upward, and grab 1,3 shifts out, and opens door, and reverse operating can close to the doorstep.
Described grab 1,3 is provided with screw hole 14, and screw is fixed together grab and door body 2 by this hole, and this grab is provided with tongue 15 and is used to block casing.
Described eccentric wheel 13 is fixed together by pin 6 and last connecting lever 5.
This mode quick operating valve mode reasonable use the casing cavity space, and the switch door is convenient.The design of grab has not only solved the anti-quick-fried problem of casing, and has solved the problem of flameproof gap, makes flameproof gap adjustable, thereby brings convenience to the gap maintenance.The mode of opening the door that this high-voltage switch gear is new greatly facilitates operation, operation and maintenance.

Fig. 2 is the hook structure schematic diagram;
Fig. 3 is the architecture figure of eccentric wheel and handle.
Embodiment
Embodiment of the present utility model is as follows:
The purpose of this utility model provides a kind of quick opening structure of underground mine use explosion-proof switch, and this structure has solved that the speed of opening the door is slow, inner loaded down with trivial details, the problem of the bad control of flameproof gap.Top board 4, upper supporting plate 8 and lower carrier plate 11 are welded on the casing, elevating lever 9 is fixed together by screw 7 and last connecting lever 5, last connecting lever 5 and following connecting lever 12 are fixed on the body 2, elevating lever 9 slides up and down in the pilot hole of upper supporting plate 8 and lower carrier plate 11, door body and casing are linked together, and handle 10 is that the center is fixed together with the door body by pin 6 and last connecting lever 5 with the eccentric shaft of eccentric wheel 13.Left and right sides grab 1 and last grab 3 are screwed on the door body by screw hole 14, and following grab 3 is screwed on casing by screw hole 14.When opening the door, the handle 10 of upwards raising one's hand, eccentric wheel 13 slide on upper supporting plate 8, pin 6 with on move, move up thereby drive to go up connecting lever 5, elevating lever 9, door body 2 and following connecting lever 12, grab shifts out, outwards the rotary door body is opened door.The mode that the high-voltage switch gear of this device adopts door to move up and down is opened the door, and utilizes 12 grabs and pad to control flameproof gap.
