Abstract
The utility model is a kind of automatic safety door for vertical shaft fall arrest, and it comprises each steelframe of each block buffering cushion block in the left and right being fixed on pit mouth side and left and right; Crossbeam is connected with between two steelframes; Also comprise tensioning and be connected to each dragline steel cable in left and right between cushion pad and crossbeam; Protective door comprises the stand parallel with two dragline steel cables and two steelframes of residing plane, residing plane and stand orthogonal, be connected to stand bottom and be positioned at the flatrack on rear side of stand; The left and right sides of stand is respectively with the guide pipe that a trend is parallel to each other with two steelframes, and two dragline steel cables poling homonymy guide pipe separately.Protective door is opened and closed import automatically with cage lifting, without the need to human attendance, further increases vertical shaft protection safety grade.
Description
Technical field
The utility model relates to a kind of automatic safety door for vertical shaft fall arrest.
Background technology
At present, prevent personnel or equipment from crashing into the protection mechanism of vertical shaft from ground both at home and abroad, be generally mounted in one protective door outside cage.Each after cage is gone into the well, all need technician and be responsible for shutting protective door., still there is certain potential safety hazard in essence in such protective door, if due to the error of people, forget and shut protective door, or protective door is not locked and is in open mode for a certain reason, at this moment, very likely generation personnel or equipment crash into the serious accident in well.This kind of safety misadventure has occurred a lot of at home.
Utility model content
Technical problem to be solved in the utility model is, a kind of automatic safety door for vertical shaft fall arrest is provided, without the need to human attendance, cage go into the well after protective door automatically seal well head side, on cage, well opens protective door simultaneously, to improve vertical shaft protection safety grade further.
The technical solution of the utility model is as follows:
For an automatic safety door for vertical shaft fall arrest, it is characterized in that: it comprises is fixed on each steelframe of each block buffering cushion block in ground left and right, pit mouth side and left and right, and steelframe is positioned at the outside of homonymy cushion pad; Crossbeam is connected with between two steelframes; Also comprise tensioning and be connected to each dragline steel cable in left and right between cushion pad and crossbeam, two dragline steel cables and two steelframes parallel to each other; Also comprise a protective door, described protective door comprises the stand parallel with two dragline steel cables and two steelframes of residing plane, residing plane and described stand orthogonal, be connected to stand bottom and be positioned at the flatrack on rear side of stand; The left and right sides of described stand is respectively with the guide pipe that a trend is parallel to each other with two steelframes, and two dragline steel cables poling homonymy guide pipe separately.
Preferably, between described stand and flatrack, stirrup is connected with.
Good effect of the present utility model is: protective door is opened and closed import automatically with cage lifting, without the need to human attendance, further increases vertical shaft protection safety grade.Be arranged on protection mechanism outside cage because of a variety of causes lose protection time, can effectively prevent personnel or equipment from falling from vertical shaft.There is the features such as safe and reliable, automatic protection, structure are simple.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structure, the schematic shapes of the utility model protective door.
Detailed description of the invention
The utility model is further illustrated below in conjunction with drawings and Examples.
As Fig. 1, the utility model comprises and is fixed on each block buffering cushion block 6 in ground left and right, pit mouth side and is fixed on each steelframe 1 in ground left and right, pit mouth side, and steelframe 1 is positioned at the outside of homonymy cushion pad 6.Crossbeam 2 is connected with between two steelframes 1.Also comprise tensioning be connected to each dragline steel cable in left and right 3, two dragline steel cables 3 between cushion pad 6 and crossbeam 2 and two steelframes 1 parallel to each other.
The utility model also comprises protective door 5 as shown in Figure 2, protective door 5 comprises the stand parallel with two dragline steel cables 3 and two steelframes 1 of residing plane, residing plane and described stand orthogonal, be connected to stand bottom and be positioned at the flatrack on rear side of stand, refer on rear side of described stand at the upper side of vertical shaft, it is relative to the front side of side, ground.The left and right sides of described stand is respectively with the guide pipe 51 that a trend is parallel to each other with two steelframes 1, and two dragline steel cables 3 poling two guide pipes 51 respectively.
Still as Fig. 2, be connected with transverse bar 52 and lower transverse bar 53 between each guide pipe 51 in left and right of described stand, between upper transverse bar 52 and lower transverse bar 53, be connected with vertical fender rod 59.Described flatrack is surrounded by lower transverse bar 53 end to end successively, left cross bar 54, rear transverse rod 55 and right cross bar 57, and is connected with horizontal type fender rod 56 between lower transverse bar 53 and rear transverse rod 55.
In order to improve the intensity of whole protective door 5, between guide pipe 51 and rear transverse rod 55, be connected with stirrup 58.
Cage is when down-hole, and protective door 5 is seated on cushion pad 6, and its flatrack is visited above Shaft bank; When cage is by shown in steel cable 4(Fig. 1) when being brought up, the flatrack of cage top upwardly protective door 5 makes protective door 5 move up along dragline steel cable 3, and the mine car in cage just can freely have been come in and gone out.When under cage is along vertical shaft, protective door 5 relies on deadweight to fall along dragline steel cable 3 along with cage, is parked on cushion pad 6, plays the effect preventing personnel or equipment pendant well.
