Description
Technical field
The utility model relates to the energy absorber in the anti-sport car safety device of a kind of mining product, especially inclined shaft.
Background technology
The anti-sport car safety device of inclined shaft mainly is installed on various mine lower curved sections, to prevent that after mine car from breaking off relations sport car taking place causes personnel's the injures and deaths and the heavy losses of property.In the anti-sport car safety device of known inclined shaft, energy absorber is as one of member of necessity, plays a part very crucially, and the quality of its performance directly affects the safety of catcher.Energy absorber adopts the clamping plate type structural form more at present, rely on steel plate that the energy-absorbing program is carried out in the clamping of steel wire, its friction force size is regulated by clamping the strength size, realize regulating by the bolt degree of tightening and clamp the strength size, yet screw tightening can't be accomplished balance and measurement, too tight steel rope and clamping plate are integral, steel rope is broken easily; Too the pine steel rope be easy to be drawn out.Therefore, it is constant to provide a kind of friction strength, and energy-absorbing effect is good, and can also accomplish that repeated use changes energy absorber product easily, particularly urgent for safety in production.
Summary of the invention
In order to overcome existing poor, the awkward deficiency of mining energy absorber product energy-absorbing effect, the utility model provides a kind of energy absorber, and its friction strength is constant, energy-absorbing effect is good, and can repeated use, it is convenient to change, thus can be from the work of the textural assurance energy-absorbing of essence member safe and reliable.
The technical scheme that its technical matters that solves the utility model adopts is: design a kind of energy absorber, which comprises at least at cylindrical shell 1 one ends fixing flange 8 and fixing thereon big bearing 12, it is characterized in that: on the end plate of cylindrical shell 1 other end, be fixed with little bearing 9, main shaft 2 passes flange 8, the center of big bearing 12, be fixed on by anchor shaft 3 on the little bearing 9 of cylindrical shell 1 bottom, on anchor shaft 3, be socketed with spring 7, the end plate of one end of spring 7 and cylindrical shell 1 bottom is fixed, the other end is fixed on the lower end of main shaft 2, on main shaft 2, be fixed with movable friction plate 4, be fixed with static friction sheet 5 on the link stopper 6 of cylindrical shell 1, movable friction plate 4 is alternately captiveed joint with static friction sheet 5.
Main shaft 2 transverse axis cross sections in the described cylindrical shell 1 are square or regular hexagon.
Described anchor shaft 3 is cylinders.
Described movable friction plate 4 is that the dislocation of multilayer overlapping dynamically is connected with static friction sheet 5, and movable friction plate 4 and static friction sheet 5 are discoid bodies.
When mine car bump car bumper, the stressed energy absorber rope sheave that affects of the steel rope at car bumper two ends, thereby driving main shaft rotates, owing on the main shaft movable friction plate is housed, the static friction sheet break-in closely that dynamic friction sector-meeting and cylindrical shell are spliced under the effect of length of spring compressed bounce together, so rotate the energy absorber rope sheave certain pulling force (greater than 60000N) must be arranged then, energy is bigger in a flash for mine car bump pushing-off the wagons net, if adopt rigidity to connect, steel rope is directly stressed, broken easily, the kinetic energy that energy absorber produces in the time of then can clashing into car bumper to mine car absorbs under the friction drag effect gradually, and under the friction drag effect, the energy absorber rope sheave stops operating at last, thereby the reverse drag steel rope utilizes car bumper to block mine car.
Useful technique effect of the present utility model is, the friction drag that utilizes the tight break-in between many sound friction lining that the compression of spring bounce forms to bring, effectively absorbed the bump kinetic energy of mine car in short time, eliminate the instantaneous effusion of energy that rigid impact brings, realized the security purpose of prevention derailing accident; Its rational sound friction lining structural form, it is reliable and stable to make that transformation of energy absorbs program, meets the intrinsic safety requirement of mining product, in addition, but the utility model energy absorber repeated use also, and it changes convenient, be fit to batch manufacturing, reach the science control of product design, safety performance.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the structural representation of the utility model energy absorber.
Among the figure: 1, cylindrical shell; 2, main shaft; 3, anchor shaft; 4, movable friction plate; 5, static friction sheet; 6, link stopper; 7, spring; 8, flange; 9, little bearing; 10, rope sheave; 11, wire clips; 12, big bearing.
The specific embodiment
In Fig. 1, the utility model energy absorber is included in fixing flange 8 of cylindrical shell 1 one ends and fixing big bearing 12 thereon, the other end is fixed with end plate and at the little bearing 9 of end plate center fixation, main shaft 2 passes the center of flange 8 and big bearing 12, be fixed with rope sheave 10 that connects steel rope and the wire clips 11 that is fixed on the rope sheave 10 in its bottom, the center of process flange 8 and big bearing 12 enters on the cylindrical shell 1 in-to-in main shaft 2 and is fixed with movable friction plate 4, movable friction plate 4 overlaps dislocation between the static friction sheet 5 of cylindrical shell 1 inwall, main shaft 2 one ends are captiveed joint with anchor shaft 3 one ends, and anchor shaft 3 other ends are captiveed joint with little bearing 9; Be socketed with spring 7 on the anchor shaft 3, spring 7 one ends and end plate are fixed, and the other end is captiveed joint with main shaft 2.
Main shaft 2 transverse axis cross sections in the cylindrical shell 1 are the endoporus socket of square and movable friction plate 4 in the present embodiment, and the main shaft 2 transverse axis cross sections in the cylindrical shell 1 can also be regular hexagons; Anchor shaft 3 is cylinders; In the cylindrical shell 1 inboard perisporium link stopper 6 is arranged, static friction sheet 5 is set on the link stopper 6 of cylindrical shell 1; Movable friction plate 4 is that the dislocation of multilayer overlapping dynamically is connected with static friction sheet 5; Movable friction plate 4 and static friction sheet 5 are discoid bodies.
Spring 7 is sleeved on the anchor shaft 3 in the cylindrical shell 1, and after spring 7 was compressed under external force, spring 7 had certain compression bounce.
When the car bumper in the anti-sport car safety device of mine car bump, the stressed rope sheave 10 that affects energy absorber of the steel rope at car bumper two ends, thereby driving main shaft 2 rotates, because main shaft 2 is equipped with movable friction plate 4, static friction sheet 5 break-in closely that movable friction plate 4 can be spliced with cylindrical shell 1 under the effect of length of spring compressed bounce must have certain pulling force (greater than 60000N) so will rotate 10 of rope sheaves together.Energy is bigger in a flash for mine car bump pushing-off the wagons net, if adopt rigidity to connect, steel rope is directly stressed, broken easily, the kinetic energy that energy absorber produces in the time of then can clashing into car bumper to mine car absorbs under the friction drag effect gradually, and under the friction drag effect, the rope sheave 10 of energy absorber stops operating at last, thereby the reverse drag steel rope utilizes car bumper to block mine car.
One of member of necessity of the anti-sport car safety device of the utility model energy absorber conduct, be applied to various mine lower curved sections, to prevent that after mine car from breaking off relations sport car taking place causes personnel's the injures and deaths and the heavy losses of property, will give the generation of preventing accident, carry out to keep the safety in production and bring positive effect.
