Description
Technical field
The present invention relates to coal mine elevator technical field, more particularly to a kind of mine hoist and its test side of breaking off relations
Method.
Background technology
According to《Safety regulations in coal mine》The 413rd article of regulation " catching device after new installation or overhaul, it is necessary to carry out
Break off relations test, it is qualified after can use.To the vertical cage catching device in use, 1 test of not breaking off relations should be carried out per 6 months,
1 test of breaking off relations is carried out every year." colliery auxiliary shaft, using single wire winding type mine elevator, supports the use 5 ton tank cages, is vertical
Pit shaft.Each cage uses 2 check bands, supports the use BF112 catching devices.According to《Safety regulations in coal mine》Require, stop every year
Do when producing maintenance and break off relations completely test, first do once the slack tank test of not on-load, then try again the test with heavy load.
For many years, having been used up following scheme carries out unhook test：Cage hoisting improves again 1.5 meters to after upper well head, in cage bottom
Well head closed with 66 cun of steel pipes, be paved with 30 pieces of planks on steel pipe, 300, plank upper berth saw foam straw bag, after the tank pressure reality that falls,
Becket bridle is removed on tank cap, detacher is hung, is then risen after 1.5 meters of tank in catching device chock and check band, the cage master of cage both sides
The positions such as pull bar, derrick buffer make marks, then carry out subsequent operation.After finishing slack tank test, then remove saw foam straw bag, wood
Plate, steel pipe, push 2 section loaded vehicle after the horizontal retort that falls, then play 1.5 meters of tank, then spread the secondary behaviour such as steel pipe, plank, saw foam straw bag again
Make.
, there is following drawback in this original method：
1st, slack tank test can not then do weight tank test after finishing, it is necessary to the steel pipe, plank, saw foam straw bag original laying
Remove, fall it is canned enter loaded vehicle after lay again steel pipe, plank, saw foam straw bag.Two hook cages add up laying and the dismounting for needing 4 times
Repetitive process, pole is lost time.2nd, laying and dismounting steel pipe, plank, saw foam straw bag etc. every time, personnel construct at station in well head,
It is absolutely unsafe.
3rd, the objects such as operation, steel pipe, plank, straw bag are repeated several times and easily fall into pit shaft, cause the accident.
4th, steel pipe, plank, saw foam straw bag etc. are laid and is removed, needs many people in well head both sides to transmit object, personnel demand amount
Greatly, lavish labor on.
The content of the invention
The technical problem to be solved is to provide for a kind of Height Adjustable mine hoisting with cage
Machine.
To achieve these goals, the technical scheme taken of the present invention is：A kind of mine hoist, including mine hoisting
Machine body, mine hoist body is arranged with ground well head track in inclination angle, and the bottom of the mine hoist body is arranged can
Elevating lever is adjusted to be connected with ground well head track, the mine hoist body is connected between winding cage by level overlap joint bridge,
The level overlap joint bridge is connected with mine hoist body by horizontal adjustment oil cylinder；The fixing end of the horizontal adjustment oil cylinder connects

Connect.
Preferably, the winding cage is storage cage, and interior setting of the storage cage carries car, carries and pull-cord is led on car with prop drawing strand
Car connects.
Preferably, the adjustable lifting bar includes the left-handed screw on top and the right handed screw of bottom, left-handed screw and the right side
By adjusting the connection of adjustable lifting bar between rotation screw rod, the right handed screw is affixed with ground well head track by lock screw.
Preferably, the horizontal adjustment oil cylinder is pneumatic oil cylinder.
The invention also discloses a kind of test method of mine hoist, comprises the steps,
After A, cage hoisting to upper well head, 1.5 meters of stopping productions are proposed in continuation；
B, it is transported to well head entry side with the above-mentioned cage of mining ordinary flat handlebar；
C, the cage is fixed on wellhead ground track；
D, being fully contacted using the horizontal lap segment of hydraulic jack adjustment and cage tank inner orbit；
E, the inclination angle of track is adjusted using orbit inclination angle adjusting apparatus, and make horizontal lap segment gradually be the level of state；
F, the drawing hoist of cage opposite side gradually put rope, through inside cage, by haulage cable along the device
Upward slope orbit transports are to entry side；
The connection of G, fag end and loaded vehicle, is drawn loaded vehicle to tank by drawing hoist traction；
H, with hydraulic jack by horizontal lap segment jack-up, make front end overlapping part completely disengage from tank inner orbit；
I, hereafter, fall tank, removes cage becket bridle, installs detacher, plays tank, does and starts unhook test.
The invention has the beneficial effects as follows：The unhook assay device realizes the mistake between the test of cage slack tank and weight tank test
Cross the stage, it is to avoid canopy tank sequence of maneuvers repeatedly, effectively save working time, artificial amount, reduce security risk, improve
Work efficiency and work quality.
