Description
Technical field
The present invention relates to coal mine gig technical field, particularly a kind of mine hoist and unhook test method thereof.
Background technology
" new to install or falling protector after overhaul according to " safety regulations in coal mine " the 413 article regulation, unhooks must be carried out and test, can use after qualified.To the vertical cage falling protector in use, within every 6 months, test of not breaking off relations for 1 time should be carried out, carry out test of breaking off relations for 1 time every year." colliery auxiliary shaft use single wire winding type mine gig, supporting the use 5 tons of cages, is shaft of vertical well.Each cage uses 2 check bands, supports the use BF112 catching device.According to " safety regulations in coal mine " requirement, during annual stop production to overhaul, do test of breaking off relations completely, first do once the slack tank test of not on-load, the test of the band heavy load that then tries again.For many years, adopt following scheme to carry out unhook test: after cage hoisting to upper well head, to improve 1.5 meters more always, well head bottom cage 66 cun of steel pipes are closed, steel pipe is paved with 30 pieces of planks, 300, plank upper berth saw foam straw bag, after the tank pressure that falls is real, becket bridle removed by tank cap, hang detacher, make marks in positions such as the catching device chock of cage both sides and check band, cage main tie, derrick energy dispersers after then playing 1.5 meters, tank, then carry out subsequent operation.After finishing slack tank test, then remove saw foam straw bag, plank, steel pipe, push 2 joint loaded vehicle after the horizontal retort that falls, then play 1.5 meters, tank, more again spread the secondary operations such as steel pipe, plank, saw foam straw bag.
, there is following drawback in this original method:
1, slack tank test then can not do the test of heavy tank after finishing, and the steel pipe must laid original, plank, saw foam straw bag are removed, and falls to cannedly entering again to lay steel pipe, plank, saw foam straw bag after loaded vehicle.Two hook cages add up the laying of needs 4 times and the repetitive process of dismounting, lose time in pole.2, each laying and dismounting steel pipe, plank, saw foam straw bag etc., personnel stand in well head construction, are absolutely unsafe.
3, repeatedly repeat, the objects such as steel pipe, plank, straw bag easily fall into pit shaft, cause the accident.
4, lay and remove steel pipe, plank, saw foam straw bag etc., needing the many people in well head both sides to transmit object, personnel demand amount is large, lavishes labor on.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of Height Adjustable mine hoist with cage.
To achieve these goals, the technical scheme that the present invention takes is: a kind of mine hoist, comprise mine hoist body, mine hoist body and ground well head track are that inclination angle is arranged, the bottom of described mine hoist body arranges adjustable lifting bar and is connected with ground well head track, described mine hoist body with overlap bridge by level between winding cage and be connected, described level overlap joint bridge is connected by Level tune oil cylinder with mine hoist body; The fixed end of described Level tune oil cylinder connects mine hoist body, and telescopic end connects level overlap joint bridge; Described mine hoist is connected with drawing hoist by pull-cord.
Preferably, described winding cage is storage cage, arranges and carries a car, year car leads pull-cord and is connected with drawing hoist in described storage cage.
Preferably, described adjustable lifting bar comprises the left-handed screw on top and the right handed screw of bottom, by regulating adjustable lifting bar to be connected between left-handed screw with right handed screw, described right handed screw by lock screw and ground well head track affixed.
Preferably, described Level tune oil cylinder is pneumatic oil cylinder.
The invention also discloses a kind of test method of mine hoist, comprise the steps,
After A, cage hoisting to upper well head, continuation is proposed 1.5 meters of stopping productions;
B, be transported to well head entry side with the above-mentioned cage of mining ordinary flat handlebar;
C, this cage is fixed on wellhead ground track;
D, utilize fully contacting of the horizontal lap segment of hydraulic ram adjustment and cage tank inner orbit;
E, use orbit inclination setting device adjust the inclination angle of track, and horizontal lap segment is the level of state gradually;
The drawing hoist of F, cage opposite side puts rope gradually, through cage inside, by haulage cable along the upward slope orbit transports of this device to entry side;
G, fag end are connected with loaded vehicle, are drawn loaded vehicle in tank by drawing hoist traction;
H, with hydraulic ram by horizontal lap segment jack-up, make front end overlapping part depart from tank inner orbit completely;
I, after this, fall tank, removes cage becket bridle, installs detacher, plays tank, does and starting test of breaking off relations.
The invention has the beneficial effects as follows: this unhook experimental set-up achieve the test of cage slack tank and heavy tank test between transition period, avoid canopy tank sequence of maneuvers repeatedly, actv. is saved work-hours, is manually measured, and reduces security risk, improves work efficiency and workmanship.
