Description
Technical field
The invention belongs to rubber-tired cart technical field, be specifically related to a kind of rubber-tired cart buffer stop, occurring unexpected for protecting railless free-wheeled vehicle.
Background technology
Railless free-wheeled vehicle is used by many modernization large-scale mines at present in a large number.But in use, because driving over the speed limit, the rubber-tired cart speed runaway sport car phenomenon that unsuccessfully causes of brake failure, driver's breakthrough symptoms or engage a gear occurs repeatedly, once there is rubber-tired cart derailing accident, often cause serious personnel's injury and property damage, become a large hidden danger of mine safety.
The bargh of current use rubber-tired cart transport solves mainly through two kinds of modes this type of derailing accident counter-measure:
1, in the different locations in tunnel, pile up junked tire along wall both sides, once there is car speed derailing accident out of control, constantly adjusted by driver and drive direction vehicle body and junked tire generation friction, make vehicle reduction of speed.But this control mode, relevant with the situation such as the speed of vehicle, the driving ability of driver, subjective factor is very strong, and vehicle rollover easily occurs, and result of use is very unreliable, hidden danger and interception result extreme difference.
2, offer one section of blind lane of going up a hill at the end in tunnel, floor, tunnel is covered with a large amount of stone (section at long and steep downgrade on similar express highway.All there is a uphill way at a certain distance.When car brakeing inefficacy, speed runaway, vehicle will in artificial driving undershoot section last time of driver, play the object of deceleration, braking), when rubber-tired cart generation brake failure, engage a gear failure constant velocity in emergency circumstances out of control, driver driving vehicle directly sails this tunnel into, plays the effect of deceleration, braking.But, because similar blind lane of going up a hill quantitatively is restricted, once miss, just actv. control cannot be carried out to vehicle.And this type of tunnel offered in the construction of tunnel is less, sport car position and this type of tunnel often distant, vehicle is constantly accelerated in generation sport car hourly velocity, and often vehicle cannot sail into according to desirable state, very easily causes the major accident of car crash.
Above two kinds of modes are as a kind of brake snub pattern of rubber-tired cart speed runaway accident, and Reliability comparotive is poor, and potential safety hazard is very big, produces little effect.
Rail mining car class sliding train in inclined lane protective device, generally uses at present in coal mine transport.This type of buffer stop is mainly divided into: rigidity interception and flexible hold-up interception.This type of buffer stop, when mine car generation sport car, is tackled mine car car body, has reached the effect stopping that mine car is descending.But this buffer stop cannot be used in the derail avoidance of rubber-tired cart speed runaway, and reason is as follows:
1, the energy absorber of rail mining car class sliding train in inclined lane protective device, the resistance of generation is very large.Therefore usual after interception mine car, mine car produces gross distortion all.If apply its interception rubber-tired cart, comparatively major injury can be produced to rubber-tired cart and passengers inside the car after interception, very easily cause the major accident of car crash.
2, according to " safety regulations in coal mine " 370 requirements, use in inclined shaft with rails during tube-train hoisting and must install normally closed buffer stop.Existing rail mining car class sliding train in inclined lane protective device, place to use is the inclined shaft of regular upper and lower mine car, and that is the impact up and down that is subject to mine car of rising and falling of rail mining car class Type Protection Device for Inclined Shaft Runaway Car is larger.If be arranged on rubber-tired cart transport inclined gallery, due to rubber-tired cart is irregular up and down, so unordered the rising and falling of protective device can be caused to affect the normal operation of vehicle.
