Description
Technical field
The present invention relates to a kind of underground mine use electrical control cubicles, particularly the location locking mechanism of pull movement in a kind of electrical control cubicles.
Background technology
Along with the raising of coal mining automaticity, the degree of concentration of control of Underground Mine explosion-proof electric equipment is more and more higher.Mining explosion-proof vacuum feeder switch is a kind of protective device that down-hole is commonly used, and it, as having hree-phase symmetry electric leakage and leakage latching protection during master switch, is the earth leakage protective backup protection of branch switch.Movement is the core component of mining explosion-proof vacuum feeder switch, movement is the execution unit of the reliable grafting of three-phase busbar realizing major loop and circuit breaker, in the installation and maintenance process of electrical control cubicles, often need to extract out and push operation movement, often there is movement and push not in place and that withdrawn position is limited problem.
Summary of the invention
The invention provides a kind of underground coal mine explosion-proof tank movement pull location locking mechanism, solve the movement existed in existing electrical control cubicles movement maintenance process and push not in place and that withdrawn position is limited technical problem.
The present invention solves above technical problem by the following technical programs:
A kind of underground coal mine explosion-proof tank movement pull location locking mechanism, comprise explosion-proof tank casing, movement pull guide is provided with in explosion-proof tank casing, the side of movement is provided with movement wheel shaft, movement wheel shaft is provided with road wheel, movement is movably arranged in movement pull guide by road wheel, guide vane end stop is fixedly installed at the outside lower end of movement side, guide vane end stop is provided with spacing cotter way, the outboard end of movement pull guide is provided with breach, swing arm hinge is provided with in breach, front end and the swing arm hinge of swing arm are hinged, the front inner face of swing arm is provided with spacing minor axis, the spacing cotter way that spacing minor axis and guide vane end stop are arranged is that activity is combined together, the medial surface of swing arm is provided with and supports fork hinge, support the upper end thereof of fork on support fork hinge, the lower end supporting fork is provided with a mouth, the medial surface of explosion-proof tank casing is provided with back shaft, the mouth and the back shaft activity that support fork lower end are combined together.
The top end face of back shaft is bolted with pin outside movement.
This invention ensures that the reliable grafting of three-phase busbar of major loop on movement and circuit breaker, facilitate the extraction maintenance of movement, have the advantages that mechanism is simple and easy to use.
Accompanying drawing explanation
Fig. 1 is that the present invention overlooks the structural representation on direction;
Fig. 2 is the structural representation of swing arm 8 of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail:
A kind of underground coal mine explosion-proof tank movement pull location locking mechanism, comprise explosion-proof tank casing 1, movement pull guide 2 is provided with in explosion-proof tank casing 1, the side of movement 3 is provided with movement wheel shaft 4, movement wheel shaft 4 is provided with road wheel 5, movement 3 is movably arranged in movement pull guide 2 by road wheel 5, guide vane end stop 15 is fixedly installed at the outside lower end of movement 3 side, guide vane end stop 15 is provided with spacing cotter way 16, the outboard end of movement pull guide 2 is provided with breach 6, swing arm hinge 7 is provided with in breach 6, front end and the swing arm hinge 7 of swing arm 8 are hinged, the front inner face of swing arm 8 is provided with spacing minor axis 14, the spacing cotter way 16 that spacing minor axis 14 and guide vane end stop 15 are arranged is that activity is combined together, the medial surface of swing arm 8 is provided with and supports fork hinge 11, support the upper end thereof of fork 12 on support fork hinge 11, the lower end supporting fork 12 is provided with a mouth 13, the medial surface of explosion-proof tank casing 1 is provided with back shaft 9, the mouth 13 supporting fork 12 lower end is combined together with back shaft 9 activity.
The top end face of back shaft 9 is bolted with pin 10 outside movement.
When for pull-out movement, swing arm 8 is lifted, spacing minor axis 14 in swing arm 8 is deviate from from the spacing cotter way 16 that guide vane end stop 15 is arranged, relieve the anti-outer sliding limiting locking to movement, again by the support fork 12 in swing arm 8 to lower swing, to 13, a mouth of fork 12 lower end setting be supported on back shaft 9, swing arm 8 is horizontally disposed be connected with movement pull guide 2, movement is facilitated farthest to pull out, the spiral shell button of pin outside movement 10 unclamped and takes off simultaneously, removing the second anticreep of movement spacing; At this moment just easily movement can be extracted out and safeguard.After maintenance work completes, after movement is pushed, support fork 12 is upwards swung, its mouth 13 is departed from back shaft 9, and after support fork 12 is overlapped with swing arm 8, again swing arm 8 is swung to upright position downwards, spacing minor axis 14 in swing arm 8 is embedded in the spacing cotter way 16 that the guide vane end stop 15 that is fixedly installed at the outside lower end of movement 3 side is arranged along with swing arm 8 to lower swing, realize the positioning and locking to movement, then pin outside movement 10 is screwed on back shaft 9, realize the positioning and locking to the second defence line of movement, effectively prevent skidding off of movement circuit breaker.
Present invention employs the mode that swing arm and pin-and-hole assembling are closed, swing arm and support bar collapsible, reduce and take up an area space, operation is flexibly light and handy.Drawer type cassette mechanism structure can be debugged in advance in whole equipment trial assembly process, facilitates the assembling of product, and ensure that safe and reliable the putting in place of electrical connector patches.
