Abstract
The utility model provides a novel energy absorption resistance used for mining at a steep slope and used during the transport when an out-of-control gliding sport car is intercepted. A drum mechanism is adopted in the device, and under the driving of the intercepted wire rope, the rotation of the screw shaft enables the nuts to move downwards along the track; the spring is extruded to generate a counterforce so that the screw shaft can generate an upward jacking force which extrudes a friction plate to generate a friction force from smallness to bigness by rotation, sliding, and friction; when the nuts move to the lower end of the drum, the nuts rotate with the screw shaft, and at the time, the friction force remains unchanged. Therewith, the impact force of the gliding object is intercepted and consumed, so that the gliding object can stop moving. The utility model can effectively absorb the energy which is released by consuming gravitational acceleration to enable mine cars, tunnels and facilities not to be damaged to realize the purpose that the novel energy absorption resistance can be quickly recovered and be put into use anew after the stopping cars intercept the gliding sport cars.

Task of the present utility model is finished in the following manner: by being installed on sensor on the rail, sport car signal out of control being passed to anti-sport car supervising device, make the wire rope on both sides on the vehilce-blocking door fall the interception sport car automatically under the effect of supervising device, at this moment rail both sides helical pressure sliding friction energy-absorption type resistance gauge that wire rope is housed is started working.This energy-absorption type resistance gauge be a kind of drum mechanism built.Under the wire rope effect, driving screw shaft by the reel rotation rotates, in the side of screw shaft upper end puts and is set with, outside friction disc, one backing plate is housed under the friction plate, on the screw shaft under the backing plate rotation set nut, nut overcoat be equipped with a slotted disk with out of stock be one with its lock, can not together rotate with screw shaft, can only be under the rotary screw axle drives, move down along guide rail in the tube, two springs that act under slotted disk and the packing ring are squeezed at this moment, produce reaction force, cause screw shaft to produce upwards top power, outside friction disc in the backing plate extruding, by rotation, slide, friction produces ascending frictional force, when nut when screw shaft moves to certain position, out of stock on the slotted disk withstood slotted disk by the block on the barrel and separated with nut, nut rotates with screw shaft, and at this moment the frictional force of friction plate remains unchanged, and wire rope continues to be subjected to pulling force constant, consume the impact force of sport car out of control with this, up to sport car stop motion out of control.
Of the present utility model simple in structure, can effectively absorb the consumption energy that acceleration of gravity discharged, make mine car, tunnel and facility are not damaged, thus the fast quick-recovery of energy behind the realization car arrester interception downslide sport car, the purpose that comes into operation again.
Below in conjunction with accompanying drawing the utility model is being described in further detail:
Fig. 1 is the front view of helical pressure sliding friction energy-absorption type resistance gauge.
Fig. 2 is the cross section cut-away view when out of stock for the block on the barrel withstands.
Fig. 3 is sleeved on the cut-away view that spiral shell axle side puts for interior outside friction disc.
Fig. 4 side of being cover B-B cut-away view.
Mainly form with reference to Fig. 1 helical pressure sliding friction energy-absorption type resistance gauge by screw shaft (5), nut (9), interior outside friction disc (17) (18), spring (11) (14), housing (16) and reel (3).Earlier nut (9) is passed through screw thread (10) rotation set on screw shaft (5).Nut (9) through last slotted disk (23), uses screw that back-up ring (19) is fixed on the nut (9) with out of stock (25) lock for one with outer then.Backing plate (7) is sleeved on side's cover (6) that the shaft shoulder (8) is gone up, interior outside friction disc (17) (18) also alternately is sleeved on screw shaft (5) and goes up (seeing accompanying drawing three).
The above screw shaft (5) that installs parts is put into the housing (16) that has guide rail (21) and block (20).Two guide rails (21) in the housing (16) are stuck in outside friction disc (18), slotted disk (23) two guide grooves separately, then successively with little spring (11), lining (12), packing ring (13), big spring (14) are enclosed within screw shaft (5) lower end, seal up bottom (15) at last, the assembling of housing (16) part finishes.
The resistance gauge upper end is that a reel (3) that wire rope (4) are housed is enclosed within it on screw shaft (5) of housing (16) upper end, again in the keyway between key (2) embedding screw shaft (5) and the reel (3), at last bolt (1) is gone up firmly, novel like this resistance gauge just can come into operation.
When sport car enters the interception door frame, the wire rope (4) of helical pressure sliding friction energy-absorption type resistance gauge is subjected to pulling force, the reel (3) that wire rope (4) are housed rotates under tension and drives screw shaft (5) rotation, because nut (9) is one with slotted disk (23) with out of stock (25) lock, so can not together rotate with screw shaft (5), can only be under the revolving force effect, move down along the interior guide rail of housing (16) (21), the spring (11) (14) that acts under slotted disk (23) and the packing ring (13) is squeezed this moment, produce reaction force, cause screw shaft (5) to produce upwards top power, the shaft shoulder (8) is by outside friction disc (17) (18) in backing plate (7) extruding, by rotation, slide, friction produces ascending frictional force, when nut (9) along screw shaft (5) when moving to certain position, pin (24) on the slotted disk (23) is withstood by the block on the barrel (19), at this moment out of stock (25) are squeezed and lose pin effect (seeing accompanying drawing 2), slotted disk (23) separates with nut (9), nut (9) is rotation together under the drive of screw shaft (5), frictional force is remained unchanged, and wire rope (4) continues to be subjected to pulling force constant.With this impact force that consumes sport car out of control, cause car stop motion out of control.
Eliminate pulling force and recover to use preceding state.Opposite spin screw shaft (5) drives reel (3) and coils back wire rope (4).Because when a directed clutch (with reference to figure four) was arranged between the square cover (6) when backward rotation, tiltedly spring (38) pressurized on the spline pin (37) in the type groove (39), so side overlapped (6) and does not rotate with screw shaft (5).Interior outside friction disc (17) (18) on the side's of being sleeved on cover (6) does not play rubbing action (seeing figure three).
