Description
Technical Field
The utility model relates to a colliery is rubber-tired car sports car protector in pit.
Background
At present, the underground coal mine rubber-tyred vehicle transportation inclined roadway generally adopts anti-collision sand barrels, steel wire ropes, wall-mounted car stoppers and other car-running protection devices. The anti-collision sand bucket has the problems of poor protection and buffering effects and influence on transportation when a large vehicle runs; the steel wire rope is arranged above the road surface, and is hung on the rope by utilizing a hook which is pre-installed on a vehicle for intercepting protection, so that the problem of hanging missing exists; the wall-mounted car arrester is complex to install, needs to capture a sports car signal and then performs interlocking action to arrest a car, and is complex in system and high in use cost.
And a plurality of deceleration strips are arranged on the bottom plate of the inclined roadway, and the speed of the underground rubber-tyred vehicle passing through the inclined roadway is reduced by the deceleration strips, but the method ensures that the underground rubber-tyred vehicle unnecessarily jolts when passing through the deceleration strips no matter going upwards or downwards, and the deceleration strips are not enough to completely stop the underground rubber-tyred vehicle when the underground rubber-tyred vehicle really runs.
The invention patent of chinese invention with publication number CN 104294779B, entitled and announced 2016.06.08, discloses a car stopping system with combined net nails, which is composed of a plurality of car stopping monomers connected in series, wherein each car stopping monomer is provided with a transmission shaft and an air discharging nail connected with the transmission shaft, a grid and a car stopping net are arranged in the car stopping system, and the car stopping net is connected with the air discharging nail.
The invention adopts the mode that the net nails are integrally connected and the nail belts are temporarily contacted, so that the net runs along with the nails, the traffic-blocking belt is threaded, and the stability and the reliability of the system are ensured. However, when the vehicle is stopped, the vehicle stopping net needs to be punctured into the tire by the aid of the deflation nails for deflation, and meanwhile, the vehicle stopping net is fixed on the tire, so that although the vehicle can be prevented from advancing, the tire is damaged and is often scrapped, and improvement is needed.
Disclosure of Invention
The to-be-solved technical problem of the utility model is how to fill prior art's above-mentioned blank, provide a colliery is rubber wheel car sports car protector in pit.
In order to solve the technical problem, the utility model discloses colliery is rubber wheel car sports car protector in pit, including the car arch that hinders that the multirow transversely arranged, above-mentioned multirow hinders the car arch and fixes its characterized in that on the inclined drifts bottom plate: each chain guard vehicle bulge consists of a left bulge, a middle bulge and a right bulge, a gap is respectively arranged between the left bulge and the right bulge on the two sides of the middle bulge and the middle bulge, the width of each gap is larger than the width of a wheel of the matched coal mine underground rubber-tyred vehicle, the gaps of the chain guard vehicle bulges are arranged into two driving channels, the longitudinal vertical bisection surface distance of the two driving channels is equal to the distance between the bisection cross section of a left front tire and the bisection cross section of a right front wheel of the matched coal mine underground rubber-tyred vehicle, a plurality of spiral steel wires are arranged on the higher side of the left bulge, the middle bulge and the right bulge which are positioned on the lowest part and the next lower part, two ends of each spiral steel wire are respectively fixed on the left bulge or the middle bulge or the right bulge connected with each spiral steel wire, and the spiral diameter of each spiral steel wire connected with each middle bulge is not more than the height of each middle bulge relative to the slope bottom plate and less than the height of the matched coal mine underground rubber-tyred vehicle relative to the slope bottom plate.
When the vehicle runs normally, two front wheels of the matched coal mine underground rubber-tyred vehicle are opposite to two driving channels, and the vehicle can stably pass through a related inclined roadway both in an ascending or descending manner.
When the running vehicle runs, a driver slightly turns the matched coal mine underground rubber-tyred vehicle to the left side or the right side and drives the matched coal mine underground rubber-tyred vehicle to the left bulge or the right bulge, and the matched coal mine underground rubber-tyred vehicle left wheel and right wheel respectively roll the left bulge or the right bulge and the middle bulge to gradually decelerate. When the matched coal mine underground rubber-tyred vehicle rolls the spiral steel wire, the spiral steel wire ropes on the two sides of the rolled spiral steel wire tend to twist and rise to clamp the wheel or hang in the tread groove of the wheel, and further twist on the wheel and the wheel shaft, and finally twist the wheel to death, so that the wheel of the matched coal mine underground rubber-tyred vehicle cannot rotate and is firmly tensioned, and the matched coal mine underground rubber-tyred vehicle with running can be rapidly stopped. Due to the design, after the matched coal mine underground rubber-tyred vehicle stops, the spiral steel wire is twisted off by using the pliers and removed, so that the matched coal mine underground rubber-tyred vehicle can recover the freedom and cannot puncture the tire.
Preferably, the other left bulges, the middle bulges and the right bulges are respectively connected with a base plate, and the base plates are fixedly connected to the higher side of the connected left bulges or the middle bulges or the right bulges and fixed on the bottom plate of the inclined roadway. By the design, the left bulge, the middle bulge and the right bulge can be more firmly fixed on the inclined roadway bottom plate.
The utility model discloses colliery is rubber-tired car sports car protector in pit has simple structure, and the vehicle is just not jolted when passing through, when taking place the sports car, can not puncture the advantage of wheel, is fit for the colliery in pit and uses.
