Description
Technical field
The utility model content 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 absorber that mine car carries out effective brake control of running.
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 easily cause mine car along the free accelerated slip of track, 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 absorber 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 absorber in mine lane mainly is to utilize friction disc that the device of friction force is provided, and this friction-disc energy absorber needs larger positive pressure that friction force is provided, and is higher to installation requirement; In addition, prior art also correspondingly in actual applications has that volume is large, the limited problems such as many 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 energy absorber that is used for colliery gradient tunnel braking mine car of good braking effect.
The technical solution that adopts for achieving the above object is such: the energy absorber that should be used for colliery gradient tunnel braking mine car comprise that was installed in the oil drum with end cap that is filled with high-viscosity oil in cylinder on the bearing and by horizontal rotating shaft, left and right end plate is equipped with at the cylinder two ends, the cylinder outer felt is wound with steel rope, and two of steel rope is connected with the roadway car bumper with first member plate respectively; The diapire center is provided with circular groove in the oil drum, vertically in cylinder, insert a vertical rotating shaft by the oil drum end cap, the bottom of vertical rotating shaft is sleeved in the circular groove of diapire in the oil drum by a secondary thrust baring, by pitman metal foam circle cylinder is housed on axostylus axostyle in the cylinder is stretched in vertical rotating shaft; One end of the horizontal rotating shaft of cylinder and the upper end of the vertical rotating shaft of oil drum are by the bevel-gear sett driving coupling.In the specific design scheme, 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, this energy absorber 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 horizontal rotating shaft are rotated, bevel gear set is also rotated thereupon, thereby driving vertical rotating shaft rotates, and then the metal foam circle cylinder that is arranged on the axostylus axostyle of vertical rotating shaft together rotates, when metal foam circle cylinder rotates in oil drum, phase mutual friction between the skeleton of high-viscosity oil and metal foam circle cylinder in the cylinder, thus the kinetic energy of mine car is converted into friction heat very soon, make the mine car braking, and mine car speed is higher, and the 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, can effectively control the stopping distance of mine car simultaneously.
