Abstract
The invention relates to an automatic bolt-disengaging device for tramcars in an inclined shaft of a mine. The automatic bolt-disengaging device comprises a tow rope hook device, an automatic bolt-disengaging device body, a winch, a steel wire rope, a ring bolt, a kick-up block, an upper platform, a rail and tramcars. The tow rope hook device is connected with a bolt-disengaging hook of the automatic bolt-disengaging device body through a balance weight rope. The automatic bolt-disengaging device body is fixed to the position over the center of a mine road of the inclined shaft through a fixing beam. The head of the first tramcar is connected with the steel wire tope through the ring bolt. The winch pulls the tramcars through the steel wire rope. When the tramcars are pulled to the ground from the shaft by the winch, the bolt-disengaging hook hooks the ring bolt in the continuous operating process, the bolt-disengaging hook moves along a guide rope through a movable pulley from low to high to lift the ring bolt so that the steel wire rope and the tramcars can be separated, and the automatic bolt disengaging function is achieved. After automatic bolt disengaging, a weight object slides down at a high speed, the bolt-disengaging hook can quickly rise along the guide rope and meanwhile drive a conductive pulley to quickly slide down along a resistance block, the winch is driven to pull the steel wire rope, and the functions of the tow rope and the hook are achieved.
Description
Technical field
The present invention relates to a kind of slope mine car and promote automatic trip bolt device, especially in mine car automatic pin shedding process, can avoid a kind of inclined shaft automatic pin shedding device that steel rope is damaged by pressure or latch is damaged by pressure simultaneously.
Background technology
In underground mining mine, slope development is a kind of developing mode of commonly using, and it need be promoted to well head by mine car by inclined shaft.In the inclined shaft hoisting process of mine car, first by shaft bottom or interruption hook personnel, adopt connecting bolt to be plugged on mine car front end, after connecting bolt is firmly connected hoisting cable with mine car, send lifting signal, hoistman starts winch, winch rolling lay winding wire ropes forms upwards tractive force, draw high mine car along lifting track to well head, cager sends stop signal, hoistman stops, mine car utilizes inertia to continue to travel in horizontal rail, when breaking through well head stop device, decoupling device, get rid of the rope personnel connecting bolt of going forward immediately to pull out, tow out steel rope, by inertia, push away away mine car, one time lifting process finishes.There are a lot of problems in this decoupling device mode:
1) adopt decoupling device manually, labour intensity is large.
2) decoupling device not in time or the too fast meeting of mine car moving velocity cause pedestrian-vehicle collision accident, the personal safety of the danger side of body.
3) decoupling device place must arrange the above staff of a people.
4) mine car travels when too fast, is difficult for decoupling device, and hoisting cable or latch can be rolled under mine car and be damaged by pressure.
Recently the rope device that gets rid of that has that ZL201220537675.6 " inclined shaft automatic decoupling device " installs by side, track throws away track by steel rope and avoids rolling, ZL201220650343.9 " slope vehicle automatic decoupling device " is pulled away from mine car top by mass by the latch after out of stock and avoids collision, ZL 200920241133.2 " inclined shaft tramcar lifting automatic unhooking device " skids off track by support bend beam and Curved-slipway by the latch after out of stock and avoids collision, they have their own characteristics each, carried out Gospel to colliery safety strap, but still there is a key shortcoming: function is complete not, after automatic trip latch, can not only protect latch but also protect steel rope.

Embodiment 1
As Fig. 1, Fig. 2-1, Fig. 2-2, Fig. 2-3, Fig. 3, shown in Fig. 4 and Fig. 5, operating process and the principle of work of inclined shaft automatic pin shedding device are as follows: in face of mine car 6 is pulled on ground from down-hole, disconnect tow strap drag hook device contactor, tighten pressure setting nut 18, manually along guide rope 10, move out of stock hook 8 to proper height, with location rope clamp 12, be clipped in mobile pulley 11 front fixing, unscrew pressure setting nut 18, connect tow strap drag hook device contactor, start to wait for that underground labour sends lifts after signal surfaceman and start winch 1 and lift mine car 6, mine car 6 from down-hole pull on ground by stop device surfaceman close winch 1, mine car 6 is because inertia continues to travel on rail 4, in mine car 6 continues operational process, out of stock hook 8 catches on band latch 7, out of stock hook 8 moves along guide rope 10 from low to high by mobile pulley 11, band latch 7 is mentioned, make steel rope 2 separated with mine car 6, play the effect of automatic trip latch.After automatic trip latch, mass 15 glides rapidly, make out of stock hook 8 along guide rope 10 fast rise and drive conducting pulley 21 to glide fast along resistance bolck 22 simultaneously, winch 1 both end voltage is increased, drive winch 1 to drag steel rope 2, when mass slides into ground 15 times, conducting pulley 21 drops to resistance bolck 22 insulation position, tow strap drag hook device circuitry cuts, tow strap action stops, and plays the effect of tow strap and pull hook; Thereby protection steel rope 2 is not rolled and avoids band latch 7 to suffer mine car 6 collisions and roll by mine car 6.
Embodiment 2
As shown in Fig. 2-1, when first segment mine car 6, by stop device 5 quilt, to be pulled on behind ground, mine car 6 is because inertia continues to travel, and out of stock hook 8 catches on band latch 7 head annulus, starts to carry out the work of automatic trip latch.
Embodiment 3
As shown in Fig. 2-2, out of stock hook 8 catches on after band latch 7 head annulus, and mine car 6 still to overtake, out of stock hook 8 moves along guide rope 10 from low to high by mobile pulley 11, band latch 7 is mentioned, and steel rope 2 is separated with mine car 6, and the work of automatic trip latch completes.
Embodiment 4
As Figure 2-3, after the work of automatic trip latch completes, mass 15 drives conducting pulley 21 to glide rapidly, tow strap drag hook device circuit resistance reduces, and winch 1 both end voltage increases, and drives winch 1 to drag steel rope 2, when mass slides into upper mounting plate 3 15 times, conducting pulley 21 drops to resistance bolck 22 insulation position, tow strap drag hook device circuitry cuts, and tow strap action stops.Meanwhile, mass 15 is pulled away from mine car 6 tops by counterweight rope 13 by out of stock hook 8, plays the effect of tow strap pull hook.
