The inclined shaft anti-sliding device has been used in mine inclined shaft tunnel transportation for decades, and is mainly divided into the following parts:
the first is a rigid fence, namely when a car runs off a hook and the like in the transportation of an inclined shaft roadway, a fence door is closed to implement interception, rigid collision is realized during the interception, no buffer facility is provided, and the buffer effect and the safety are very poor.
The second one is friction type, when the tramcar running is detected by a speed detection means, the intercepting fence is started in time, the fence drives the connecting rope to start the buffering brake device, the friction type buffering brake device is typically a pressing plate type or friction plate type, and the braking force cannot be calibrated along with the change of pretightening force and temperature during braking, so that the braking force cannot be ensured. The friction type is that the friction force between the dynamic friction pair and the static friction pair provides braking force, the working condition of use may not act for years, once the friction type does not act for a long time, under the action of underground moisture, dust and chemical gas medium, the friction pair can corrode and rust, the pretightening elasticity can change greatly along with the prolonging of time, and the braking force of corresponding equipment can not be ensured. The effect of the actual buffer device is not good, and certain potential safety hazard exists.

The invention has the beneficial effects that:
(1) the invention cancels the necessary mechanical interception system in the prior art, automatically triggers and starts the steel belt buffer braking device immediately when the vehicle is in a series and is out of line, and realizes stable buffer braking at the initial stage of the vehicle taking out. Effectively avoid derail collision and eliminate potential safety hazard. And the device has simple structure, convenient installation and maintenance, stable and reliable action and greatly improved safety. The invention can avoid rigid interception and collision to realize stable buffer braking through mechanical triggering, rail locking and steel belt plastic deformation devices, and the constant braking force is controllable and can be customized according to different working conditions. The buffer braking device cancels a necessary mechanical interception system in various traditional buffer braking, not only avoids the generation of on-site non-safety environment in a roadway, but also fundamentally avoids the safety accidents of derailment, rollover, mine car, loaded equipment and materials damage, outward throwing and pedestrians, equipment and the roadway during braking. Further reducing the potential safety hazard when the mining inclined shaft runs.
(2) The source braking impact load is smaller: the prior art can not brake in time when the sports car runs, the sports car can be passively intercepted to brake when the sports car runs to a position provided with an intercepting device, and at the moment, the sports car runs freely along an inclined plane in an uncontrolled manner, so that impact load and energy are rapidly increased by multiple times or ten times along with the increase of running distance, and the difficulty is increased for buffering and braking. Once the technology is used, the buffer braking system is started immediately once the sports car runs, and the increase of impact energy is controlled from the source. Compared with the prior art, the impact load is smaller.
(3) No mechanical interception avoids derailment collision: the technology cancels a mechanical intercepting device of the mine car, fundamentally solves the problems of derailment of the mine car, rigid collision between the mine car and the mine car, between the mine car and equipment, between the mine car and object materials and the like during the interception of the mine car, and avoids the loss such as damage and the like.
(4) The system performance is reliable: the system is fully mechanically and automatically controlled, and utilizes the energy stored by a spring and the energy existing in the running process, and the mechanical trigger starts to implement buffer braking. And no electric control and electric component are provided, so that the influence of environmental factors such as humidity, dust, chemical gas, service life, static electricity and the like on the electric component under the severe underground working condition is avoided, and the reliability of the equipment is improved.
(5) The application range is wide: the original technology needs to occupy the space at two sides of the inclined shaft tunnel and is used for laying the interception foundation and the interception facilities on the interception foundation, so that a plurality of inclined tunnels with pedestrian passages cannot be laid. Meanwhile, for the inclined lane of the long slope larger than 300 meters, the existing energy absorbers of various standard models reach the upper limit or are not economical to arrange. The technology is not limited by the interception space and the length of the ramp, thereby greatly increasing the application range of the technology
(6) The safety environment is good: the technology changes external passive interception into internal braking of the mine car, cancels an interception device in an inclined roadway, avoids interception and collision, eliminates hidden dangers of rigid collision equipment, roadway damage and personal safety, ensures that a safety channel is smooth and unobstructed, and effectively improves the safety environment.
(7) The use cost is low: according to the requirements of relevant national safety regulations and the current situation of various conventional energy absorbers, the arrangement of one wave and three grades of anti-running vehicles in inclined roadways in various forms is about 300 meters, concrete foundation arrangement intercepting equipment needs to be arranged for excavating multiple positions of underground roadways, and the arrangement is difficult and high in cost for the ultra-long ramp, particularly the inclined roadways above kilometers. The buffer braking system is arranged at the bottom of the mine car, no intercepting equipment is arranged, a concrete foundation is not needed, and the length of the slope is irrelevant, so that the on-site layout cost is low, the setting cost of the long slope is lower, and the advantage is larger. Meanwhile, once the original technology is intercepted, the original intercepting collision equipment needs to be replaced in time, and the use cost is increased.
(8) Laying, mounting and maintaining are convenient: in the prior art, due to the fact that impact load is large, enough concrete foundations need to be excavated and filled on two sides of a track to install intercepting equipment, due to underground limitation, installation is unchanged, and in case of car falling off, intercepting collision and damage inevitably occur, the collision equipment needs to be replaced in time, and installation and maintenance are inconvenient. The buffering brake device has the advantages of simple structure, stable action, safety and reliability, and no component damage in case of the vehicle falling off, so that the device is very convenient to install, use and maintain.
