Description
Technical Field
The invention relates to the technical field of mine hoist safety doors, in particular to a mine auxiliary shaft safety door locking device.
Background
The auxiliary shaft cage safety doors in mines in China are mainly hydraulically controlled to be opened and closed, but at present, the auxiliary shaft cages of most mines are not locked with lifting signals and safety doors, or only mechanical locking is realized, so that great hidden danger is brought to the safety production of the mines.
Disclosure of Invention
The invention aims to solve the technical problem of providing a mine auxiliary shaft safety door locking device which is used for solving the problem that an auxiliary shaft cage, lifting signals and a safety door are lack of effective locking in the prior art described in the background art.
In order to achieve the above object, the present invention provides the following technical solutions: a mine auxiliary shaft safety door locking device comprises
The vertical beam is provided with a rotating groove at the upper end of the inner side wall;
The rotating plate is rotatably arranged in the rotating groove;
the through hole is arranged on the vertical beam;
One end of the pull rope is connected with the rotating plate, and the other end of the pull rope penetrates through the through hole in a sliding manner and is connected with the bolt;
The limiting hole is arranged at the position corresponding to the bolt on the driving column;
The pull rope can pull the bolt to enable the bolt to enter and exit the limiting hole so as to limit or release the driving column.
Preferably: a sliding plate is sleeved on the outer circumferential wall of the bolt, a positioning sleeve is arranged on the vertical beam, the sliding plate is arranged in the positioning sleeve and is in sliding contact with the positioning sleeve, and the sliding plate is connected with the vertical beam through a spring.
Preferably: the rotary plate is provided with a backing plate, and the top of the cage is provided with a top plate corresponding to the position of the backing plate.
Preferably: the vertical beam is provided with a plurality of positioning rings which are vertically arranged, and the stay cord penetrates through the positioning rings in a sliding manner.
Preferably: the inner wall of the through hole is smooth.
The beneficial effects of adopting above technical scheme are:
According to the application, the rotating plate can rotate in the rotating groove through lifting of the cage, so that the pull rope can pull the bolt, the bolt enters or leaves the limiting hole, when the bolt enters the limiting hole, the driving column cannot rotate, and the safety door cannot be opened.
Drawings
FIG. 1 is a schematic diagram of the structure of a mine auxiliary shaft safety door locking device.
Wherein: vertical beam 10, cage 20, drive post 30, emergency exit 31, rotation plate 40, rotation groove 41, backing plate 42, top plate 43, stay cord 50, through hole 51, retainer ring 52, latch 60, limiting hole 61, slide plate 62, spring 63, and positioning sleeve 64.
Detailed Description
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
In the present embodiment, as shown in FIG. 1, a mine auxiliary shaft safety door locking device comprises
The vertical beam 10, the upper end of the inner sidewall has rotary grooves 41;
a rotation plate 40 rotatably disposed in the rotation groove 41;
a through hole 51 provided on the vertical beam 10;
A pull rope 50, one end of which is connected with the rotating plate 40, and the other end of which is connected with the bolt 60 through the sliding through hole 51;
the limiting hole 61 is arranged on the driving column 30 at a position corresponding to the bolt 60;
Wherein the pull cord 50 is capable of pulling the latch 60 such that the latch 60 enters and exits the limiting aperture 61 to limit or release the drive post 30.
Preferably: the outer circumferential wall of the bolt 60 is sleeved with a sliding plate 62, the vertical beam 10 is provided with a positioning sleeve 64, the sliding plate 62 is arranged in the positioning sleeve 64 and is in sliding contact with the positioning sleeve 64, and the sliding plate 62 is connected with the vertical beam 10 through a spring.
Preferably: the rotating plate 40 is provided with a backing plate 42, and the top of the cage 20 is provided with a top plate 43 corresponding to the position of the backing plate 42.
Preferably: the vertical beam 10 is provided with a plurality of positioning rings 52 arranged vertically, and the pull rope 50 slides through the positioning rings 52.
Preferably: the inner wall of the through hole 51 is smooth.
Specific implementation of this embodiment:
When the cage 20 moves upwards to the top, the top plate 43 applies thrust to the base plate 42 to enable the rotating plate 40 to rotate, the rotation of the rotating plate 40 pulls the pull rope 50 to enable the pull rope 50 to pull the plug pin 60, the sliding plate 62 applies pressure to the spring 63 at the moment, the spring 63 is compressed, the plug pin 60 is pulled out of the limit hole 61, and the driving post 30 can drive the safety door 31 to rotate under the driving of driving equipment to open the safety door 31;
When the cage 20 needs to descend, the driving post 30 drives the safety door 31 to rotate, then the rotating plate 40 rotates under the pulling force of the pulling rope 50, the spring 63 will restore to the original state, and the spring 63 will drive the bolt 60 to enter the limiting hole 61, so that the driving post 30 is limited to rotate.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and improvements could be made by those skilled in the art without departing from the inventive concept, which falls within the scope of the present invention.
