Abstract
The utility model discloses an electric automatic wellhead anti-running safety door, which comprises a rail set and a safety door, wherein the rail set includes an upper rail and a lower rail, the safety door is mounted on the rail set and capable of moving along the rail set, a prop pulling hoist is mounted at the back of the safety door and connected with the safety door via a pulling rope, a front limit switch and a rear limit switch are respectively mounted at the front end and the rear end of the rail set, and a snatch block mounted at the front end of the rail set is connected with the rear end of the safety door via a pulling rope and used for fixing the front end of the safety door. The safety door can be opened or closed by the aid of a limit switch. The electric automatic wellhead anti-running safety door has the advantages of increasing transportation safety of inclined shafts and providing a safety guarantee to inclined shaft transportation.
Description
Technical field
The utility model relates to a kind of inclined shaft and prevents that mine car from from the safety device that slips, specifically being the electronic automatic safety door of a kind of anti-sport car well head.
Background technology
Mine car is the main vehicle during slope is produced, because the inclined shaft outlet has certain gradient, mine car takes place easily from slipping back the well accident.For preventing the generation of accident, each well head of national requirements will be realized the safeguard procedures of " slope three retainings ".Comprising at well head safety door being installed, present safety door is artificial safety door.Form by upper and lower track and the door that is installed on the upper and lower track and can move in orbit.This old-fashioned safety door needs personnel and manpower to open, and brings certain potential safety hazard, waste of manpower for the top cager personnel.
Summary of the invention
For overcoming the above-mentioned deficiency of prior art, the utility model provides a kind of anti-sport car well head electronic automatic safety door.
The present invention realizes with following technical scheme: the electronic automatic safety door of a kind of anti-sport car well head comprises the track of being made up of upper and lower track, the safety door of installing in orbit and moving in orbit; In the back of safety door a drawing hoist is installed, drawing hoist is connected with safety door by pull rope; Install a front limit switch, back limit switch respectively at the forward and backward two ends of track; The front end of track is installed a snatch block, and snatch block is connected by pull rope with the rear end of safety door, is used for fixing the front end of safety door.Utilize travel switch to realize opening and closing automatically of safety door.
The beneficial effects of the utility model are, the anti-electronic automatic safety door of sport car well head has improved the safety in the inclined shaft transportation, and transportation provides safety guarantee to inclined shaft,
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: 1, safety door track, 2, safety door, 3, the front limit switch, 4, the back limit switch, 5, snatch block, 6, drawing hoist.
The specific embodiment
As shown in drawings, the anti-electronic automatic safety door of sport car well head comprises the safety door track 1 that upper and lower track is formed, the safety door 2 that is installed on the safety door track 1 and can on safety door track 1, moves, in the back of track 1 drawing hoist 2 is installed, drawing hoist 2 is connected with safety door 2 by pull rope; Install a front limit switch 3, back limit switch 4 respectively at the forward and backward two ends of track 1; The front end of track 1 is installed a snatch block 5, and snatch block 5 is connected by pull rope with the rear end of safety door 2.Front limit switch 3, back limit switch 4 all adopt travel switch.
Operating principle is: after well on the mine car passed through safety door, safety door 2 was closed, and was closed to back front limit switch 3 and stopped drawing hoist 6 operations, and safety door 2 stops automatically.When opening safety door, safety door moves backward, when back limit switch 4 is touched in its rear end, stops drawing hoist 6 operations.Thereby realized opening or closing when putting in place and can stop automatically.
