Description
Technical field
The utility model belongs to mining equipment controller, particularly a kind of urgency of dragline type lock-switch of closing down.
Background technology
On mining equipment, all need to arrange the anxious lock-switch of closing down, the existing urgency lock-switch of closing down comprises dragline type and push button; The anxious lock-switch of closing down of existing dragline type, it can not keep suddenly stopping state after the anxious lock-switch pull-up of closing down, after operating personnel loose one's grip, the lock-switch of suddenly closing down resets, when there are the following problems like this: if encounter the starting switch of equipment in maintenance process, equipment just can move, and has the potential safety hazard of maintenance.
Summary of the invention
For the deficiencies in the prior art, the urgency that the utility model the has designed a kind of dragline type lock-switch of closing down, and can keep the anxious lock status of closing down, prevent the generation of the contingency in maintenance process, and the utility model can be indicated the position of the anxious lock-switch of closing down, convenient operation personnel understand the position of the anxious lock-switch of closing down, and are convenient for people to operate.
The utility model is achieved through the following technical solutions:
Mining intrinsic safety type crashstop closedown switch, comprise cabinet housing, cabinet enclosure interior is provided with travel switch, it is characterized in that: the side of described cabinet housing is provided with the anxious latch mechanism of closing down of stay cord, the anxious latch mechanism of closing down of described stay cord comprises the push rod that stretches into cabinet housing, the afterbody of push rod is provided with the chamber that is threaded, the leading portion of pull bar is socketed with guide plate, the leading portion of pull bar is connected in the chamber that is threaded, and push rod compresses guide plate, pull bar is arranged on the inside of drag link sleeve, and the rear end of pull bar stretches out in drag link sleeve, on described drag link sleeve, be provided with the gathering sill that guide plate is led, on the drag link sleeve of the end of gathering sill, be provided with swivelling chute, on described pull bar, be arranged with the torsion spring in tensioning state, one end of torsion spring is connected on guide plate, the other end is connected on drag link sleeve, on the rear end of described pull bar, be connected with indicator board, indicator board is axial perpendicular to pull bar.
In sum, the utlity model has following beneficial effect:
The swivelling chute that the utility model arranges in drag link sleeve and gathering sill and be arranged on the guide plate on pull bar, when gathering sill coordinates with guide plate on the one hand, can lead to the direction of motion of pull bar, and can be at the anxious lock-switch of closing down during in blocking, position to pull bar keeps, the swivelling chute arranging is used for guide plate from gathering sill skids off, the release of torsion spring tension force, pull bar is rotated, guide plate snaps in swivelling chute, releasing orientation to the anxious lock-switch of closing down keeps, suddenly close down lock-switch in releasing orientation, state regardless of start stop switch, whole equipment can not move, prevented the generation of the contingency in maintenance process, the indicator board simultaneously arranging on pull bar can be indicated the state of the anxious lock-switch of closing down, convenient operation personnel operate, prevent the generation of misoperation, in addition, when indicator board can all reset, indicator board can drive pull bar revolution, convenient operation personnel drive, reduced operation easier.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the half sectional view of the vertical view of Fig. 1;
In figure, 1 is indicator board, and 2 is drag link sleeve, and 3 is cabinet housing, and 4 is torsion spring, and 5 is swivelling chute, and 6 is guide plate, and 7 is push rod, and 8 is travel switch, and 9 is the chamber that is threaded, and 10 is gathering sill, and 11 is pull bar.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Mining intrinsic safety type crashstop closedown switch as depicted in figs. 1 and 2, comprise cabinet housing 3, cabinet housing 2 inside are provided with travel switch 8, it is characterized in that: the side of described cabinet housing 2 is provided with the anxious latch mechanism of closing down of stay cord, the anxious latch mechanism of closing down of described stay cord comprises the push rod 7 that stretches into cabinet housing, the afterbody of push rod 7 is provided with the chamber 9 that is threaded, the leading portion of pull bar 11 is socketed with guide plate 6, the leading portion of pull bar 11 is connected in the chamber 9 that is threaded, and 7 pairs of guide plates 6 of push rod compress, pull bar 11 is arranged on the inside of drag link sleeve 2, and the rear end of pull bar 11 stretches out in drag link sleeve 2, drag link sleeve 2 is fixedly connected on the side of cabinet housing 3, on described drag link sleeve, be provided with the gathering sill 10 that guide plate is led, on the drag link sleeve 2 of the end of gathering sill 10, be provided with swivelling chute 5, on described pull bar 11, be arranged with the torsion spring 4 in tensioning state, one end of torsion spring 4 is connected on guide plate 6, the other end is connected on drag link sleeve 2, on the rear end of described pull bar 11, be connected with indicator board 1, indicator board 1 is axial perpendicular to pull bar 11.
In sum, the utlity model has following beneficial effect:
