Description
Technical field
The utility model relates to the mining electronic equipment technical field, relates in particular to a kind of mine explosion-suppression quick operating valve mechanical interlock mechanism.
Background technology
In the prior art, the quick operating valve interlocking device of mining electronic equipment belongs to indirect interlocking, and quick operating valve and isolating switch be control separately.In order to guarantee to be closed condition when the flame proof property and the quick operating valve of isolating switch flame proof housing when switching on; And quick operating valve when opening isolating switch can't convert "on" position into, need to divide two actions to operate, i.e. state through handle control isolating switch on one side; Need pull the state of door-hinge on one side again manually with the control quick operating valve; Two states can not carry out simultaneously, complex operation step, and be difficult for processing and assembling.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned technology, and a kind of mine explosion-suppression quick operating valve mechanical interlock mechanism is provided, and can control the state of isolating switch and quick operating valve simultaneously, is convenient to operation.
The utility model adopts following technical scheme for realizing above-mentioned purpose: a kind of mine explosion-suppression quick operating valve mechanical interlock mechanism, comprise handle mechanism, and door lock axle, block cover plate, door-hinge is spacing and rotating shaft; Cam in the said handle mechanism and block cover plate are formed cam mechanism; Said cam is connected with handle, and said block cover plate is fixed on the said door lock axle; The two ends of said door lock axle flexibly connect with an end of said rotating shaft respectively, and the other end of said rotating shaft is connected with door-hinge is spacing.
Preferably, being shaped as ellipse and cooperating of said cam with the block cover plate, cam can be stirred the block cover plate and drive the door lock axle and do linear movement.
Preferably, in order the door lock axle to be resetted and to be convenient to processing and assembling, said door lock axle is divided into plurality of sections, regulates double-screw bolt through double end each other and connects.
The beneficial effect of the utility model is: drive oval-shaped cam rotation through rotary handle; Cam is on the one hand at the state of axially controlling isolating switch; Cam is stirred the block cover plate on the door lock axle when rotating on the other hand, and the block cover plate drives the door lock axle and does linear movement.When handle rotates to " energising " state, the axial right motion of door lock drives " door-hinge is spacing " and rotates to horizontal level, and restriction quick operating valve door-hinge moves upward, and quick operating valve is pinned; When handle rotates to " outage " state, back-moving spring resets door lock axle (to left movement), and the door lock axle drives that door-hinge is spacing to rotate to an angle simultaneously, removes the restriction to the quick operating valve door-hinge, and the quick operating valve door-hinge can move upward, the quick operating valve release.Under the situation that guarantees requirement of explosion proof, the utility model operating procedure is simple, controls the state of isolating switch and quick operating valve simultaneously, and parts are convenient to processing and assembling.

Among the figure: 1, cam; 2, door lock axle; 3, block cover plate; 4, door-hinge is spacing; 5, rotating shaft; 6, quick operating valve; 7, door-hinge; 8, door lock back-moving spring; 9, guide pad; 10, double end is regulated double-screw bolt; 11, isolating switch; 12, handle mechanism; 13, handle.
Embodiment
Embodiment below in conjunction with accompanying drawing and preferred embodiment detailed description the utility model.Extremely shown in Figure 4 like Fig. 1; A kind of mine explosion-suppression quick operating valve mechanical interlock mechanism; Comprise with handle mechanism 12 in spacing 4, the rotating shaft 5 of handle 13 cam 1, door lock axle 2, block cover plate 3, the door-hinge that are connected and the door lock axle is fixed on the guide pad 9 on the flame proof housing (not looking among the figure); Said block cover plate 3 is fixed on the said door lock axle 2 and with said cam 1 and cooperates; Cam be shaped as ellipse, form cam mechanism with the block cover plate, purpose is to make cam can stir the door lock axle to do linear movement.For cam mechanism is resetted, said door lock axle is provided with back-moving spring.One end of the two ends of said door lock axle 2 and said rotating shaft 5 flexibly connects; The other end of said rotating shaft 5 is connected with door-hinge spacing 4, door-hinge spacing with quick operating valve 6 on door-hinge 7 cooperatively interact, when handle rotates to " energising " state; The axial right motion of door lock; Drive " door-hinge is spacing " and rotate to horizontal level, restriction quick operating valve door-hinge moves upward, and quick operating valve is pinned; When handle rotates to " outage " state, back-moving spring resets door lock axle (to left movement), and the door lock axle drives that door-hinge is spacing to rotate to an angle simultaneously, removes the restriction to the quick operating valve door-hinge, and the quick operating valve door-hinge can move upward, the quick operating valve release.Rotating shaft 5 is spacing through the flame proof housings support, and guarantees the flame proof gap.
For convenient for assembly, axle is unsuitable long, and axle is decomposed into several parts, and the link position of door lock axle is regulated double-screw bolt 10 through double end and connected, and its objective is: 1, for easy to assembly in the flame proof housing, it is oversize that the door lock axle is unfit to do; The length that needs the fine-tune door lock shaft when 2, assembling is to adapt to the installation site in the flame proof housing.Back-moving spring plays 8 to the door lock axle is resetted.
Operation principle: during use, rotary handle drives cam 1 rotation, and cam 1 is on the one hand at the state of axially controlling isolating switch 11, and cam is stirred the block cover plate 3 on the door lock axle 2 when rotating on the other hand, and block cover plate 3 drives door lock axle 2 and does linear movement.When handle rotates to " energising " state, the axial right motion of door lock drives door-hinge spacing 4 and rotates to horizontal level, and restriction quick operating valve 6 door-hinges 7 move upward, and quick operating valve is pinned; When handle rotates to " outage " state, back-moving spring resets door lock axle 2 (to left movement), and the door lock axle drives door-hinge 7 spacing rotating to an angle simultaneously, removes the restriction to quick operating valve door-hinge 7, and the quick operating valve door-hinge can move upward, the quick operating valve release.
When quick operating valve during in open mode, the position of quick operating valve door-hinge is in the state of the spacing rotation of limiting door axle, makes switch knob can not rotate to " energising " state, realizes the mechanical interlocking of isolating switch and quick operating valve with this.The utility model is directly controlled isolating switch and door lock mechanism through handle, and safe and easy and simple to handle, processing technology is simple.Can directly control this interlocking device through control isolating switch handle, make under the isolating switch "on" position, quick operating valve can't be opened; During the quick operating valve open mode, isolating switch can't be switched on, and has guaranteed the flame proof requirement greatly.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
