Background
With the rapid development of mining technologies such as coal mines and metal mines, the production capacity of the mines is greatly improved, and the scale of the mines is larger and larger. Mine transportation is an indispensable important component in the mine production process, and relates to the production of the whole mine, wherein the mine transportation has wide related aspects and high technical requirements, and whether the mine transportation can normally run or not. At present, most mines carry mine cars as bearing devices for carrying and discharging gangue, and mine car transportation has the advantages of being simple in structure, flexible in transportation and the like, so that the mine cars play an irreplaceable role in mine transportation.
Since the mine car does not have a power device, the mine car needs to be pulled by other power devices when being transported, wherein the two modes of pulling the mine car by a winch and pulling the locomotive are mainly divided into two modes, and the essence of the two modes is that the mine car is pulled to be transported by directly connecting a traction rope with the mine car. However, mine transportation environment is very harsh, mine car tracks are complex and changeable, and sometimes a plurality of uphill slopes and curves and the like are needed for one-time transportation of the mine car. At the same time, the mine cars are heavy in weight when transporting ore and gangue, which is a great challenge for the traction device, thereby causing many problems: when the mine car is transported, the problem that the mine car slips or slides due to sudden disconnection of the traction rope often occurs, so that a series of safety accidents are caused, and the safety production of the mine car is threatened. At present, in the mine production process, in order to ensure the safe transportation of the mine car, the strengthening and supervision of a traction device and equipment of the mine car are emphasized, and most mine cars do not have enough safety measures in the transportation process, so that the protection capability is very limited.
Disclosure of Invention
Aiming at the situation, the invention discloses an emergency braking device for a mine car to overcome the defects of the prior art, and aims to effectively solve various problems caused by mine car transportation in the production process of a mine and smoothly realize safe transportation of the mine.
In order to achieve the above purpose, the technical scheme of the invention is as follows: the T style of calligraphy base of device and the bottom connected to the frame of mine car, both wings are connected with the rotation support about the base lower part, the design of support end has the voussoir, base upper portion design has perpendicular draw-in groove, the pouring weight that can reciprocate is designed in the draw-in groove, the microscler lifter plate of pouring weight sub-unit connection, lifter plate both wings edge is through connecting rope and rotating support middle part and being connected, the design of pouring weight middle part has the fixed screw, the platform that pulls of mine car is fixed at bottom frame front end, it has the slope draw-in groove to pull platform middle part design, slider sub-unit connection rope in the draw-in groove is connected through. If the traction rope is suddenly disconnected in the transportation process of the mine car, the weight block and the sliding block slide downwards under the action of gravity, and meanwhile, the rotating brackets on the two wings of the base rotate downwards to drive the wedge block to be clamped into the contact position of the wheels and the track, so that the emergency braking of the mine car is completed.
The invention has the beneficial effect that the mine car is innovatively designed, so that the mine car has good emergency braking capability. The device ingenious design double-clamping groove and slider feed back the traction state of haulage rope to the device base promptly with the help of pulley and connection rope, and arresting gear on the base simultaneously effectively brakies the mine car in time. On the other hand, the weight block of the device is specially designed with a fixing screw, and the weight block can be manually moved up and down and fixed when the mine car is in a non-traction state, so that the mine car is in a braking or free state, and the safety of the mine car is ensured. The device simple structure, convenient operation, not only can be automatic carry out timely effectual braking to the mine car under emergency, also can effectively protect the mine car at ordinary times, improved a series of problems that cause by the mine car transportation in the mine production process greatly, have the significance to mine safety production, have very high practical application and worth.
