Description

Mechanical type mine car automatic anti-running-away car device

Technical field

The utility model relates to a kind of mine car brake equipment, especially a kind of mine car automatic anti-running-away device of avoiding the mine car derailing accident to take place.

Background technology

On the mine car that in present bargh, uses also relevant for the device of mine car emergency braking, and modal be that the braking spanner is set on mine car, realize emergency braking thereby act on over the ground by braking spanner control brake pawl.Also there is patent documentation to disclose the technology of roadway Catcher for mine car car device in addition.Liu patentee husband minister is in patent " mine car automatic anti-running-away car the device " (patent No.: 200520080822.1) of application on March 8th, 2005.The technical scheme of this utility model is as follows: catcher is installed on the mine car, this apparatus structure is: a retaining pawl is installed on the mine car axle, retaining pawl is spacing by electromagnetic lock near the position, working end, electromagnetic lock links to each other with the control circuit in the intrinsically safe circuit case is electric, on the rotor of explosion-proof power generator motor gear is installed, the tramcar wheel inboard also is processed with tooth, motor gear and tramcar wheel engagement, and explosion-proof power generator links to each other with the control circuit in the intrinsically safe circuit case is electric.During the mine car normal operation, tramcar wheel drives explosion-proof power generator and produces electric current, but can not make the transistorized collector and emitter conducting of the single crystals pulse transformer in the control circuit, have only when the speed of a motor vehicle of mine car reaches a field planting, unijunction transistor conducting when the voltage that electrical generator produces is increased to certain value, make its work to electromagnetic lock power supply, thus the falling of control brake pawl.First kind of above-mentioned mine car brake equipment, its automatism is poor, and when the mine car high-speed motion, braking itself is with regard to dangerous property; Above-mentioned second kind of mine car shortcoming is to need to use electric elements, and electric elements easily lost efficacy in abominable mine environment, cost height, deficiency in economic performance, and complex structure.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, can realize automatic anti-running-away, mechanical type mine car automatic anti-running-away car device safe and reliable to operation.

For achieving the above object, the utility model adopts technical scheme as follows: a kind of mechanical type mine car automatic anti-running-away car device, it comprises a retaining pawl that acts on sleeper, axle, spring, welded plate, fixed pedestal, steel rope and clutch, and all be installed on the mine car support body, retaining pawl one end is hinged by hinge and fixed pedestal, fixed pedestal is welded on the mine car support body, the retaining pawl other end is the working end, retaining pawl links to each other with the axle collar by steel rope away from the position, working end, the axle collar is welded on the axle, axle mounting is on the welded plate that is welded on the mine car support body, and can slidably reciprocate, the front end of axle links to each other with hauling rope with steel rope, be with spring at front end position near axle, one end of spring contacts with the shaft shoulder of axle, the other end is pressed on the welded plate under the car body, the tip of the axis links to each other with clutch, clutch is by attaching parts 1, attaching parts 2, attaching parts 3 and torsion spring are formed, attaching parts 1 links to each other with axle, attaching parts 2 is hinged with attaching parts 1, attaching parts 3 is hinged with attaching parts 1, and torsion spring is installed between attaching parts 3 and the attaching parts 1; When work, attaching parts 3 can form closed loop with attaching parts 2 under the effect of torsion spring, and the steel rope A of a back mine car can hang in the closed loop, and when sport car took place, when attaching parts 3 collided with link stopper, closed loop was opened, and realized the chain braking of mine car group.

During the mine car normal operation, retaining pawl is suspended under the mine car support body and is failure to actuate; When sport car takes place when, mine car and hauling rope break away from, steel rope A no longer is subjected to the tension of hauling rope, be returned to virgin state and impeller-hub slides backward at the spring of tension lower compression, in the process that slides backward, steel rope B is lax, and the retaining pawl by gravity falls, catch sleeper, realize arresting; Elastic force is too big when preventing that spring from replying, and axle is ejected go, and a bolt is housed on axle, plays good positioning action; In addition, the clutch of shaft end bumps against the link stopper that is welded on the vehicle body in the process with the motion of axial back, and clutch is opened, and the steel rope A and the clutch of the mine car of next are broken away from, and is not subjected to tension, thereby realizes the interlock effect between several the mine cars; When needs manually promote mine car, can hang over steel rope A on the hangers on the car body, retaining pawl and ground are disengaged.

After using such scheme, the brake portion structure is simplified, and can realize chain braking, the safety factor height, and pure mechanical control can adapt to the abominable natural environment in mine, and applicability is strong.

Below in conjunction with drawings and Examples the utility model is further described.

The specific embodiment

Embodiment 1

In embodiment as shown in Figure 1, mark as follows:

1-car body, 2-hangers, 3-steel rope A, 4-bolt, 5-welded plate 1,6-spring, 7-axle, the 8-axle collar, 9-steel rope B, 10-fixed pedestal, 11-retaining pawl, 12-welded plate 2,13-attaching parts 3,14-attaching parts 1,15-attaching parts 2,16-torsion spring, 17-link stopper, 18-automobile body welding plate.

The steel rope A (3) of first mine car is linked to each other with hauling rope, the steel rope A (3) of a back mine car is suspended on the clutch of last mine car, and closed clutch. during the motion of hauling rope pulling mine car, axle 7 is subjected to the tension of the steel rope A (3) that links to each other with hauling rope, travel forward, compression spring 6, in the process of pulling, because steel rope B (9) length that links to each other with axle 7 is certain, therefore when axial advancement is moving, steel rope B (9) drives retaining pawl 11 upward movements, makes retaining pawl 11 break away from ground; During the mine car normal operation, retaining pawl 11 is suspended under the mine car support body and is failure to actuate; When sport car takes place when, mine car and hauling rope break away from, steel rope A (3) no longer is subjected to the tension of hauling rope, be returned to virgin state and impeller-hub 7 slides backward at the spring 6 of tension lower compression, in the process that slides backward, steel rope B (9) is lax, and retaining pawl 11 by gravitys fall, and catch sleeper, realization is arrested, elastic force is too big when preventing that spring from replying, and axle is ejected go, and a bolt 4 is housed on axle, play good positioning action, in addition, the clutch of shaft end is in the process with the motion of axial back, and the attaching parts 3 of clutch bumps against the link stopper 9 that is welded on the vehicle body, clutch is opened, the steel rope A (3) of next mine car breaks away from clutch, is not subjected to tension, thereby realizes the chain braking between several the mine cars; When needs manually promote mine car, can be suspended to pulling steel rope A (3) on the hangers 2 on the vehicle body to it, retaining pawl and ground are disengaged.
