Description

Tipper automatic vehicle-blocking apparatus

Technical field the present invention relates to a kind of stop device, the overturning automatic vehicle-blocking apparatus especially used in mining process.

In background technology mining process, the mine car filling coal or other ore needs to enter in cage and tipper and carries out upset discharging.In order to ensure the smooth discharging of mine car, not altering tank, just needing car interior car arrester.The stop device of present employing, is not complex structure, needs manual operation exactly, not only manufacture complexity, difficult in maintenance, in use also causes inconvenience.

" a kind of can anti-mine car alter the In-pot Car Retarder of tank " patent (application number: 201110307643.7) disclosed in No. CN103029719A, Chinese patent, include depression bar, depression bar is connected with crank II by bearing pin, the pull bar II be connected with crank II is connected with pull bar I by adjusting nut, pull bar I is connected with crank I by bearing pin, resistance claw I is connected with pull bar I, and resistance claw II is connected with pull bar II; Described stop device also includes opening and closing device.This stop device relies on the outer tramcar wheel of tank to press down opening and closing device, and the pressure head of opening and closing device acts on depression bar, is opened by resistance claw by the transmission of crank I, crank II, pull bar I, pull bar II; When tramcar wheel departs from opening and closing device, In-pot Car Retarder relies on resistance claw self-weight reset, is closed by stop device.The weak point of this patent is: mine car has two groups of wheel level front vehicle wheels and rear wheel, and current wheel is separated from In-pot Car Retarder when closing device and relies on resistance claw self-weight reset, is closed by stop device, thus stops rear wheel motion; Stop device relies on resistance claw self-weight reset, and response time cannot accurate assurance, and the resistance claw kinetic energy that relies on own wt to produce inadequate, therefore can cause and use inconvenience.

Summary of the invention object of the present invention will provide a kind of tipper automatic vehicle-blocking apparatus exactly, in guarantee transmission simultaneously accurately, improves serviceability and stability.

In order to achieve the above object, tipper automatic vehicle-blocking apparatus provided by the invention is except having barrier structure, pressing and turn except structure and drive mechanism, also there is stop block structure, wherein, barrier structure has two covers, and often overlap barrier structure and be made up of stopper, block axis bearing, gear shaft, nut, recoil spring, gear shaft is fixed on rail outer lower portion by block axis bearing, stopper is sleeved on gear shaft by block axis bearing, can rotate around gear shaft, pressure turn structure turned by pressure, push up turn, retracing spring, pressure turn bearing seat, pressure turns and top is turned and turned bearing seat by pressure and be fixed on the outer side-lower of rail, and retracing spring one end is fixed on the rail exterior bottom other end and is fixed on top and turns bottom, drive mechanism is by pull bar, lever, axis, bottom bracket bearing seat, Compress Spring, thrust plate, torsion spring, extension spring, extension spring fixed link, clamp, dial and turn, axis is fixed on below tipper base by bottom bracket bearing seat, pull bar has two, pull bar there is setting nut, two levers are connected to the two ends of lever by knock hole, lever is fixed on the left end of axis, one end of extension spring fixed link is fixed on the other end in the middle part of axis and is connected with extension spring, one end of extension spring is fixed on below tipper base, thrust plate, Compress Spring, dial and turn, torsion spring, clamp is fixed on the right of axis successively, dial to turn and stretch out downwards, stop block structure is made up of block and L shape fixed support, and the support bracket fastened one end of L shape is fixed on below the rail frame outside tipper, and block is fixed on the support bracket fastened other end of L shape, stopper lower end is connected with pull bar by hinges.When the invention is employed, mine car enters wheel the process in tipper and jams on pressure and turn on the right side of tipper, pressure is kidnaped dynamic top and is turned and be rotated down, promote thrust plate and dial to turn to move right along axis, dial and turn the constraint of lower end disengaging block, extension spring drives extension spring fixed link and axis to rotate counterclockwise, and drive lever to rotate counterclockwise, pull bar is protruding, stopper is driven to rotate counterclockwise around gear shaft, stopper rotates to above rail and stops wheel, effect because of stopper after mine car enters tipper is limited in tipper, and thrust plate, Compress Spring, dial and to turn after departing from block constraint under effect at Compress Spring along axis to left movement and reset, mine car is allowed to topple over mineral when tipper rotates, when rotating near 60 °, the block stop be fixed on L shape fixed support is dialled to turn and is continued motion, axis, lever, extension spring fixed link is driven to do clickwise, pull bar inwardly shrinks, drive stopper to rotate clockwise around gear shaft, stopper rotates to outside rail and no longer stops tramcar wheel, and mine car moves out tipper on the left of tipper.

Tipper automatic vehicle-blocking apparatus provided by the invention has positive effect: except having barrier structure, pressure turns except structure and drive mechanism, also has stop block structure, and structure is simple, low cost of manufacture.Rely on the motion of mine car and tipper self to realize the opening and closing of stop device during use, do not need extra manual operation, achieve automatic operation; Pure physical construction, transmission is accurate, does not have time delay to respond, can improve serviceability and stability, be applicable to all tippers.
