Description
Technical field
The utility model belongs to mine machinery safety guard technical field; relate to a kind of in colliery gradient tunnel Lifting Convey process to the coal mine inclined shaft energy absorption device that mine car carries out effective brake control of running, particularly a kind of colliery gradient tunnel mine car energy-absorbing drg is with oil storage energy-absorbing cylinder.
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 the reasons such as out of stock, disconnected rope cause mine car along the free accelerated slip of track easily, because the mine car quality is large and the mine laneway inclination angle is large, the kinetic energy of mine car and speed will be very large also.In order to prevent high speed mine car bump personnel and equipment, guarantee 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 the kinetic energy of mine car 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, protection mine car and car bumper just need to be set up energy-absorbing drg class auxiliary device betwixt; transform with the kinetic energy with mine car, thereby make it braking.In the prior art, Lifting Convey equipment used energy-absorbing drg in mine lane is equipped with the drum-type energy-absorbing drg of dynamic and static friction disc group in mainly being, this friction disc group formula energy absorber is owing to need larger positive pressure that friction force is provided, cause the complicated structure of cylinder, high to installation requirement.
The utility model content
The purpose of this utility model is the problem that prior art exists is solved, and a kind of colliery gradient tunnel mine car energy-absorbing drg oil storage energy-absorbing cylinder that can conveniently install and guarantee deceleration and stopping performance and braking effect is provided.
For achieving the above object, the utility model designer has made improvement to prior art, change the existing friction disc group formula brake structure that rotates for index drum into oil stagnant friction type braking structure, its technical solution is: this oil storage energy-absorbing cylinder comprises the cylindrical shell with end cap that is filled with high-viscosity oil in, the diapire center is welded with circular groove in cylindrical shell, vertically in cylindrical shell, insert a vertical rotating shaft that can cooperate with mine car energy-absorbing drg roller shaft rotation by end cap, the bottom of vertical rotating shaft is sleeved in the circular groove of diapire in the cylindrical shell by a secondary thrust baring, by pitman metal foam circle cylinder is housed on axostylus axostyle in the cylindrical shell is stretched in vertical rotating shaft.In the specific design scheme, a finishing bevel gear cuter with mine car energy-absorbing drg roller shaft driving coupling is housed in the upper end of vertical rotating shaft, making in the oil storage cylindrical shell vertically by this finishing bevel gear cuter, rotating shaft is able to rotate synchronously with roller shaft; In addition, be arranged on the vertical rotating shaft axostylus axostyle metal foam circle cylinder by metallic framework and be embedded in the skeleton and mutually the hole of UNICOM consist of.
In the practical application, the energy-absorbing drg is installed in the gradient tunnel of colliery, one of the steel rope that twines on the energy absorber cylinder is connected on the car bumper, when the mine car of high-speed cruising and car bumper collision, to produce axial tension to steel rope, thereby haulage drum is with left, right end plate and roller shaft rotate, rotate by the vertical rotating shaft that cooperates the mechanism's (finishing bevel gear cuter) that rotates to drive in the utility model oil storage energy-absorbing cylinder with roller shaft, and then the metal foam circle cylinder on the axostylus axostyle that is arranged on vertical rotating shaft is together rotated, when metal foam circle cylinder rotates in oil storage energy-absorbing cylinder cylinder, phase mutual friction between the skeleton of high-viscosity oil and metal foam circle cylinder in the cylinder, thereby the kinetic energy of mine car is converted into friction heat very soon, make the mine car braking, and mine car speed is higher, speed of relative movement between metal foam circle cylinder and the high-viscosity oil is also higher, and brake action is also more obvious.
Compared with prior art, of the present utility model simple and reasonable, easy to install, be easy to apply, it utilizes the friction that produces between the skeleton of high-viscosity oil and metal foam circle cylinder that variable braking power is provided, can effectively absorb the kinetic energy of the mine car of running, reduce the impulsive force between mine car and the car bumper.
