Background technology
At present, in order to guarantee the safety of coal mine shaft lining elevator system, early there is explicit stipulation in country in " safety regulations in coal mine ": " in overwind height or distance of overfall, should establish the shock absorber of dependable performance.Shock absorber should be able to stop container or the bob-weight of full speed pulleying (cross and put) reposefully, and guarantee no longer oppositely to glide (or bounce-back)." reach simultaneously and lick the real-time detection of putting braking force to crossing, in the hope of can directly monitoring the size of braking cushion effect, but in the prior art, there is no the shock absorber that can fully satisfy above requirement.
As the traditional wooden wedge guide that is widely used at present, owing to be subjected to the impact of air humidity, temperature, wood grain difference, reliability is difficult to guarantee, though wirerope-winding drum-type friction shock absorber can play certain buffer action, but be difficult to prevent the reverse downslide of lifting container, and itself is subject to external environment influence friction braking, is unsuitable for the abominable condition of pit shaft.Usage comparison vertical-lift system overwind distance internal plastic non-return buffer unit widely in recent years, although can brake lifting container, also can prevent that lifting container from oppositely gliding, but put after the phenomenon in case occur to lick, the answer of this device is just very difficult, also can't the size of braking force be detected in real time.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provides a kind of steel band type buffer and supporting cage device, realize that braking is reliable, stable buffering, reset convenient, and the purpose that does not oppositely glide or rebound, can reach simultaneously and put the requirement that braking cushion effect size detects in real time to crossing to lick, then reduce in the vertical transportation licking the potential safety hazard of bringing of putting phenomenon because crossing.
To achieve these goals, the utility model comprises buffer body, pressure sensor, fixed mount, crossbeam, two fast reduction position mechanisms, two holder tank shock absorbers and container, and pressure sensor is installed in the buffer body; Fast reduction position mechanism comprises limiting stopper, slip last item and fixing last item; Holder tank shock absorber comprises steel band, slip last item, fixing last item and hold in the palm cage shoe; The lowermost end that steel band is installed in whole device passes in fast reduction position mechanism, and fixedly the last item symmetry is installed in the two ends of slip last item, limiting stopper by be installed in the slip last item and fixedly six high strength bolts at last item two ends be fixed on the surface of fast reduction position mechanism; The upper end of steel band is bolted on the buffer body, the lower end is welded on the steel plate of fixed mount bottom, slip last item and fixing last item are passed in the gap of steel band, beam welding is on the top of holder tank shock absorber, holder tank shock absorber is fastened in the fixed mount, internal welding at fixed mount is connected to bend, on the inclined-plane of holder tank shock absorber retracing spring is installed.
The holder cage shoe is normally closed, and its upper end offers the circular arc type chute, passes a bearing pin in the circular arc type chute, is fixed on the holder tank shock absorber with bolt is relative with another root bearing pin by holder cage shoe lower end, and its bearing pin around the lower end is rotated.
The beneficial effects of the utility model are: by the S deformation of steel band, produce buffer-braking power, offset the kinetic energy that container self when putting phenomenon occured to lick with this, hold reposefully the container of whereabouts, realize that braking is reliable, stable buffering, easily purpose resets, avoid the appearance of oppositely downslide or rebound phenomena, the simultaneously distortion by the dish spring produces application force to pressure sensor, make the strain sensing device that is distributed on sensor internal produce deformation, simultaneously the deformation digital signal is passed to external device (ED), just can the size that cushion effect is braked in pulleying be detected in real time, then reduced in the vertical transportation licking the potential safety hazard of bringing of putting phenomenon because crossing, and the difficulty that resets of bringing thus, the braking forces measuring hard problem.
