Description
Technical field
The utility model belongs to mine machinery safety guard technical field, relates to a kind of colliery gradient tunnel energy-absorbing drg for the coal mine inclined shaft sport car being carried out effective brake control in colliery gradient tunnel Lifting Convey process.
Background technology
In the gradient tunnel of colliery, the many Lifting Conveys that drawn to realize mine by winch of mine car.But in operational process, owing to disconnected rope, the reason such as out of stock, mine car may be along the track accelerated slip, because the mine car quality is large, the mine laneway inclination angle is large, the kinetic energy of mine car will be very large also, in order to ensure the mine hoisting transportation safety, car bumper need to be installed in inclined shaft, thus the mine car of interception art skating.As mentioned above, because mine car kinetic energy is very large, so the impulsive force between mine car and the car bumper will be very large also, in order to effectively reduce impulsive force, just need to set up betwixt the energy-absorbing drg, so that the kinetic transformation of mine car is made it braking as the friction heat homenergic.As seen, energy-absorbing drg and car bumper can consist of Type Protection Device for Inclined Shaft Runaway Car, for the requirement of this device are: (1), can effectively absorb sport car kinetic energy; (2), because the mine limited space needs to guarantee the energy absorber small volume; (3), the installation of energy-absorbing drg is simple and easy.But at present the used various energy-absorbing drgs of mine lane Lifting Convey equipment in actual applications all also corresponding have structure unreasonable, install that inconvenience, volume are large, limited many, the problem such as braking force is unstable, stopping distance is wayward of usage condition.
The utility model content
The purpose of this utility model is the problem that prior art exists is solved, provide a kind of rational in infrastructure, volume is little, installation and easy to use, deceleration and stopping performance reliable and the colliery gradient tunnel energy-absorbing drg of good braking effect.
The technical solution that adopts for achieving the above object is such: the colliery gradient tunnel that provides comprises cylinder with the energy-absorbing drg and is fixed on main shaft on the base, a left side is equipped with respectively at the cylinder two ends, right end plate also can be rotated around main shaft, the cylinder outer felt is wound with steel rope, two of steel rope is connected with the roadway car bumper with first member plate respectively, between cylinder and main shaft, be set with a secondary friction disc group, this friction disc group is comprised of dynamic friction dish and the static friction dish that a plurality of alternately contacts arrange, the dynamic friction dish is by bearing pin and a left side, right end plate connects, and the static friction dish is connected with main shaft by key.
The technical solution of the utility model also comprises: by the circular nut attaching disk spring that is used for overhead friction disc group is arranged on spindle rod.
In the practical application, this energy-absorbing drg is installed in the gradient tunnel of colliery, one of the steel rope that twines on the drg cylinder is connected on the car bumper, when the mine car of high-speed cruising and car bumper collision, to produce axial tension to the steel rope of energy-absorbing drg, thereby rotate by the rope traction cylinder, also drive left and right end plate and dynamic friction coiling main shaft and rotate, and main shaft and the maintenance of static friction dish are static; Be friction heat by the relative motion that exists between dynamic friction dish and the static friction dish and phase mutual friction with the kinetic transformation of mine car like this.Again because the dynamic friction dish is relevant with positive pressure between the two with the friction force between the static friction dish, in the utility model structure, its positive pressure can be by circular nut and belleville spring control, compare with the normally used coil spring in present this area, belleville spring can provide by less distortion larger positive pressure, thereby guarantee the energy absorber small volume, and positive pressure, friction force and braking force are stable.
Compared with prior art, of the present utility model simple and reasonable, volume is little, easy to install, be easy to apply, the friction that it utilizes a plurality of dynamic and static friction discs to produce provides variable braking power, can effectively absorb sport car kinetic energy, reduce the impulsive force between mine car and the car bumper, can effectively control the stopping distance of mine car simultaneously.
