Description

A kind of rubber-tired cart buffer stop
Technical field
This utility model belongs to rubber-tired cart technical field, is specifically related to a kind of rubber-tired cart buffer stop, is used for protecting railless free-wheeled vehicle and occurs unexpected.
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, brake failure, driver's breakthrough symptoms or hang the rubber-tired cart speed runaway sport car phenomenon that shelves unsuccessfully cause and occur repeatedly, once there is rubber-tired cart derailing accident, often causing serious personnel's injury and property loss, becoming a big hidden danger of mine safety.
This type of derailing accident counter-measure is solved by the bargh of currently used rubber-tired cart transport mainly through two ways:
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, driver constantly adjust driving direction vehicle body and junked tire produces friction, make vehicle reduction of speed.But this control mode, relevant with the situation such as driving ability of the speed of vehicle, driver, subjective factors is very strong, it is easy to vehicle rollover 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 highway.All there is a uphill way at a certain distance.When car braking inefficacy, speed runaway, vehicle will in artificial driving undershoot section last time of driver, play the purpose of deceleration, braking), when rubber-tired cart generation brake failure, hang shelves failure uniform velocity out of control in emergency circumstances, driver driving vehicle directly sails this tunnel into, plays the effect of deceleration, braking.But, owing to similar blind lane of going up a hill quantitatively is restricted, once miss, just vehicle effectively cannot be controlled.And this type of tunnel offered in the construction of tunnel is less, sport car position is often distant with this type of tunnel, and vehicle is occurring sport car hourly velocity constantly to accelerate, and often vehicle cannot sail into according to desirable state, very easily causes the major accident of car crash.
Both the above mode is as a kind of retarding braking 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 preventer, commonly uses at present in coal mine transports.This type of buffer stop is broadly divided into: rigidity intercepts and flexible hold-up interception.Mine car car body, when mine car generation sport car, is intercepted by this type of buffer stop, has reached to stop the effect that mine car is descending.But this buffer stop cannot be used in the sport car protection 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 preventer, the resistance of generation is very big.Therefore, generally after intercepting mine car, mine car has produced gross distortion all.If applying it to intercept rubber-tired cart, rubber-tired cart and passengers inside the car can be produced relatively major injury after interception, very easily causing the major accident of car crash.
2, according to " safety regulations in coal mine " 370 requirements, use in inclined shaft with rails and must install normally closed buffer stop during tube-train hoisting.Existing rail mining car class sliding train in inclined lane preventer, place to use is the inclined shaft of regular upper and lower mine car, say, that the impact up and down being subject to mine car of rising and falling of rail mining car class Type Protection Device for Inclined Shaft Runaway Car is bigger.If being installed in rubber-tired cart transport inclined gallery, due to rubber-tired cart is irregular up and down, so can cause that unordered the rising and falling of preventer affects the properly functioning of vehicle.
