A kind of stop device
Technical field
The utility model relates to production facilities field, mine, is specially a kind of control mine car operation in the mine produces, and prevents mine car from slipping even cause derailing accident, makes the mine car in the motion stop at the device that certain produces the place that needs.
Background technology
In the mine produces, stop at the place that certain production needs in order to make the mine car in the motion, make mine production and transport work reach mechanization and automation, a stop device is set on the line.Existing most of mines stop device generally is divided into pneumatic, hydraulic pressure, electronic, manual etc. from the control angle, structurally the implementation of the function of holding up traffic is had nothing in common with each other, generally speaking, be from control or all complicated from a structural point, consumable accessory is many, safeguards to account for duration, influences production efficiency.
Summary of the invention
Produce the place that needs for the Safety for mine car in realizing moving stops at certain reposefully, and existing stop device structure is complicated, consumable accessory is many, maintenance accounts for duration, influences the deficiency of production efficiency, and the utility model aims to provide a kind of stop device, this stop device does not need extrinsic motive, and simple in structure, few easy workout part, low cost of manufacture, maintenance is little, fault is easily got rid of, and safeguards weak point when accounting for, and does not need manually on duty in process of production.
To achieve these goals, the technical scheme that the utility model adopted is: described stop device, comprise the bearing that is fixed in the mine car conveying track, its constructional feature is, crescent the raming that on described bearing, can in certain angle, rotate around this bearing pin axle center by bearing pin hinged, this crescent cambered surface of raming is towards mine car direct of travel A, this crescent bottom of raming when not being subjected to external force and bearing keep in touch, when the external force that is subjected to from mine car direct of travel A with crescent ram to rotate break away from bearing, the level height of this crescent other end of raming is positioned on the axial line of wheel.
By this structure, mine car moves to stop device, because the level height on this crescent top of raming is positioned on the axial line of wheel, axletree at first contacts crescent cambered surface of raming, and crescent raming is subjected to impulsive force from mine car direct of travel A, along with mine car continue move ahead, crescent bottom of raming breaks away from bearing, crescent bearing pin rotation of raming on bearing is ramed when rotating to an angle when crescent, and mine car passes through stop device smoothly.
Mine car passes through stop device, this moment, crescent raming was not subjected to external force, crescent position of raming before bearing pin returns back to the mine car bump, crescent bottom of raming and bearing are kept in touch, can play barrier effect to the mine car that has passed through, prevent that its time from hitting, guarantee that mine car is unidirectional by stop device, but next mine car of damping again simultaneously.
Further, in the said structure, described crescent raming is preferably Heavy Weight near the more crescent other end of raming of weight of an end of mine car direct of travel, mine car by crescent raming after, because crescent bottom of raming is heavy, crescent raming is returned to mine car bump state before, and the mine car that passes through is played barrier effect, and mine car is stopped at the crescent opposite side of raming.
Further, the described crescent cambered surface inboard of raming is provided with one deck rubber pad, and in the process of holding up traffic, this rubber spacer can slow down the impact of wheel to stop device effectively, and does not influence passing through smoothly of mine car.Alleviating outside the destruction of stop device to mine car axletree and stop device itself, impact noise also greatly reduces, and has prolonged the service life of equipment simultaneously, has improved the mine production environment greatly.
The base of described bearing and track is mutually concordant, is convenient to wheel and waltzs through stop device.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, few easy workout part, low cost of manufacture, maintenance is little, and fault is easily got rid of, and safeguards the short stop device that breaks away from fully under the external force situation when accounting for, it can prevent that mine car from from slipping even cause derailing accident, not needing manually on duty in process of production substantially.Added the rubber pad buffering in addition on the mine car blocking surface, alleviated greatly in the process of holding up traffic, to the destruction of mine car axletree and stop device itself, impact noise also greatly reduces, and when having continued service life of equipment, the mine production environment also has been greatly improved.

The specific embodiment
A kind of stop device, as illustrated in fig. 1 and 2, comprise the bearing 2 that is fixed in the mine car conveying track 1, on described bearing 2, crescently ram 3 in certain angle by what bearing pin 5 hinged can rotate around these bearing pin 5 axle center, this is crescent rams 3 cambered surface towards mine car direct of travel A, this is crescent ram 3 bottom when not being subjected to external force and bearing 2 keep in touch, when the external force that is subjected to from mine car direct of travel A, 3 rotate and break away from bearing 2 with crescent raming, this is crescent, and the ram level height of 3 the other end is positioned on the axial line of wheel 4, is specially crescent 3 Heavy Weights near more crescent 3 other ends of raming of weight of an end of mine car direct of travels of raming.The described crescent 3 cambered surface inboards of raming are provided with one deck rubber pad.Described bearing 2 is mutually concordant with the base of track 1.
In Fig. 1, shown dotted line represents to ram 3 by behind the mine car bump, ram 3 to rotate around bearing pin 5, when 4 of tramcar wheels with ram 3 constitution diagram 3 that times of separating of raming.
As shown in Figure 1, in the time of mine car forward bump stop device, ram and 3 rotate counterclockwise with 4 of tramcar wheels automatically, mine car continues ahead running, raming 3 is rotated further, and rams 3 state this moment as shown in phantom in Figure 1, wait to ram 3 with 4 of wheels naturally during disengaging, half moon-shaped 3 self-returns of raming make that mine car can not be to inverted running.Added one deck rubber pad at 6 the blocking surface of raming, made 4 of wheels bump against and to obtain buffering, and do not influence passing through smoothly of mine car with stop device.
The utility model realizes that mine car is unidirectional by stop device, and can a plurality of stop devices be set in orbit as required, and mine car is parked in assigned address.
Certainly, other form that can also adopt the utility model realizes that mine car is by behind the stop device, make crescent raming automatically restore to the preceding position of mine car bump, as torsion spring etc. is installed on bearing pin, the mine car impact is passed through stop device after overcoming torsion spring elastic force, after mine car passed through, crescent raming automatically restored to position before the mine car bump under the elastic force of torsion spring.
