Abstract
The utility model relates to an energy-absorbing brake of an inclined roadway mine car. The energy-absorbing brake comprises two dead plates which are mounted on a concrete table of an inclined roadway in an upper position and a lower position through studs and a moving plate which is sandwiched and mounted between the two dead plates in an inserting way, wherein pressure springs are mounted on the upper dead plate in a pressing way through the studs with nuts, and a damping spring which is hooked with a roadway car stop is mounted at one end of the moving plate. The energy-absorbing brake disclosed by the utility model has the advantages of simple structure and convenience in mounting and use, and can provide variable brake force by utilizing the friction produced between the pressed moving plate and dead plates, so as to effectively absorb the kinetic energy of the running mine car, reduce the impact force between the mine car and the car stop and effectively control the brake distance of the mine car at the same time.
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 mine car energy-absorbing drg 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 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 the auxiliary device of energy-absorbing drg class 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 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 gradient tunnel mine car energy-absorbing drg of good braking effect.
The technical solution that adopts for achieving the above object is such: the gradient tunnel mine car energy-absorbing drg that provides have two by double-screw bolt by upper the next quiet plate and sandwiched moving plate that is inserted between two quiet plates that is installed on the gradient tunnel coagulation earthen platform, on upper quiet plate, be pressed with holddown spring by the double-screw bolt with nut, at an end that moves plate the recoil spring that articulates with the roadway car bumper be housed.
In the technique scheme, said moving plate is a long clap board that surface band is gradient, and the recoil spring that articulates with the roadway car bumper even is contained on the plate body of long clap board than Bao Yiduan.
In the practical application, an end of recoil spring is connected with car bumper, when mine car and the collision of roadway car bumper, car bumper will spur recoil spring, and then the moving plate of pulling moves; Because moving plate is between quiet plate and the lower quiet plate, and the holddown spring on the quiet plate makes and has thrust between upper and lower quiet plate and the moving plate, so when moving plate motion, because making between plate and the two quiet plates, the existence of thrust all has friction force, thereby the kinetic energy of mine car effectively is converted into friction heat, makes the mine car braking.
Compared with prior art, of the present utility model simple and reasonable, volume is little, easy to install, be easy to apply, it utilizes the friction that produces between the dynamic and static plate that compresses 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.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the right line of vision structural representation of Fig. 1.
Fig. 3 principle of work scheme drawing of the present utility model.
The title of each number designation is respectively among the figure: 1-moves plate, the upper quiet plate of 2-, 3-nut, 4-pad, 5-double-screw bolt, 6-holddown spring, 7-sleeve, quiet plate under the 8-, 9-recoil spring, 10-gradient tunnel coagulation earthen platform, 11-energy-absorbing drg, 12-mine car, 13-roadway car bumper.
The specific embodiment
Below with reference to accompanying drawing the utility model content is described further, but actual fabrication structure of the present utility model is not limited in following embodiment.
Referring to accompanying drawing, the energy absorber for colliery gradient tunnel braking mine car described in the utility model is comprised of the parts such as double-screw bolt 5, holddown spring 6 and recoil spring 9 that upper quiet plate 2, lower quiet plate 8, moving plate 1, top are provided with nut 3.Double-screw bolt 5 is fixed in two quiet plates on the gradient tunnel coagulation earthen platform 10, is pressed with holddown spring 6 by the double-screw bolt 5 with nut 3 on upper quiet plate 2.Moving plate 1 is that two surfaces are all with gradient long clap board, two quiet plates 2,8 and the contact surface of moving plate 1 also have gradient, the existence of above-mentioned gradient can guarantee in the process of leading pull plate 1, thrust between moving plate 1 and the quiet plate 2,8 progressively increases, thereby cause friction force also progressively to increase, be conducive to energy absorbing, in the time of also can guaranteeing to install for the first time, the deflection of holddown spring reduces, and is conducive to install.
In the practical application, an end of recoil spring 9 is connected with roadway car bumper 13, when mine car 12 during with 13 collision of roadway car bumper, car bumper 13 will spur recoil spring 9 and then the moving plate 1 of pulling moves; Because moving plate 1 is between the upper and lower quiet plate 2,8, and the holddown spring 6 on the quiet plate 2 make upper and lower quiet plate 2,8 and moving plate 1 between have thrust, so when moving plate 1 motion, because making between plate 1 and the two quiet plates 2,8, the existence of thrust all has friction force, thereby the kinetic energy of mine car 12 effectively is converted into friction heat, makes the mine car braking.Sleeve 7 is sleeved on the double-screw bolt 5, and can rotate around double-screw bolt 5, and the moving plate 1 of motion contacts with sleeve 7, can reduce the friction between moving plate 1 and the double-screw bolt 5.
