Description
Technical field
The utility model belongs to mining rubber-tired cart technical field, and in particular to a kind of suction of brake type with initial buffer function
It can device.
Background technology
Rubber-tired cart has largely been used at present by many modernization large-scale mines.But in use, because driving over the speed limit, stopping
Vehicle failure, driver's breakthrough symptoms or rubber-tired cart speed runaway sport car phenomenon occurs repeatedly caused by failure of putting into gear, once glue occurs
Vehicle derailing accident is taken turns, often causes serious personnel's injury and property loss, becomes a big hidden danger of mine safety.
At present, the derailing accident counter-measure of railless free-wheeled vehicle is mainly solved by two ways：
1st, in the different section in tunnel, waste tire is accumulated along wall both sides, once car speed sport car out of control occurs
Accident, steering direction vehicle body is constantly adjusted by driver and waste tire generates friction, makes vehicle reduction of speed.But this manipulation side
Formula, with the speed of vehicle, driver driving ability situations such as it is related, subjective factor is very strong, and vehicle rollover easily occurs, and uses effect
Fruit is very unreliable, and hidden danger and interception effect are very poor.
2nd, one section of blind lane of going up a hill is opened up in the end in tunnel, a large amount of stones are covered on the floor of tunnel, at a certain distance
There are one uphill way, when rubber-tired cart out of control in emergency circumstances, the driver driving vehicle that occurs brake failure, failure uniform velocity of putting into gear
This section is driven directly into, plays the effect of deceleration, braking.
However, since similar blind lane of going up a hill quantitatively is restricted, once missing, vehicle can not just be carried out effective
Control.And the such tunnel opened up in the construction of tunnel is less, and sport car position and such tunnel are often distant, vehicle
When sport car occurs, speed is constantly accelerated, and often vehicle can not drive into according to ideal state, easily cause car crash
Major accident.
