Description

Technical Field

[0001] The utility model relates to the technical field of mine transportation auxiliary components, in particular to a mine transportation tool with a safety brake. Background Art

[0002] Mine transportation refers to the underground transportation work in mines. The main task is to transport coal, followed by transporting waste rock out of the ground, transporting materials and equipment to the underground use location, and transporting personnel to and from get off work. Common ones include ground-lift steel cables, mine cars, etc. Among them, mine cars mainly run along tracks and are used to transport materials, coal mines, etc., and are widely used.

[0003] The existing mine car structural brake system has the following disadvantages when in use: the existing mine car brake system is generally composed of components such as brake discs installed on the surface of the wheel axle. When braking, it relies on the braking of the brake disc to drive the braking of the wheelset. The braking method is single, and the daily use wear is large. The brake assembly is located in the middle of the bottom of the mine car, and the brake pads are inconvenient to repair and replace. For this reason, we propose a mine transportation tool with a safety brake. Utility Model Content

[0004] The main purpose of the utility model is to provide a mine transportation tool with a safety brake. By arranging a brake mechanism at the bottom of the mine car near the track, the brake can be braked by friction with the track, thereby expanding the diversity of the brake system and effectively solving the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A mine transportation tool with a safety brake comprises a mine car and a brake mechanism. The brake mechanism is installed at the bottom of the mine car, and the brake mechanism comprises a cross bar, a trapezoidal block, a sleeve, a spring, a triangular block, a connecting rod, a brake plate and a brake pad. The bottom of the mine car is horizontally installed with a cross bar and a trapezoidal block is welded to one side of the bottom of the cross bar. The bottom of the inner wall of the mine car is fixedly connected with a sleeve and the bottom of the sleeve is installed with a brake plate close to the track surface.

[0007] Furthermore, it also includes a docking mechanism, and both ends of the mine car surface are equipped with docking mechanisms, and the docking mechanism includes a connecting pipe, a screw tube and a screw rod. Both ends of the cross bar are welded with connecting pipes extending to both sides of the mine car, and the ends of the connecting pipes are detachably connected with screw rods; both ends of the cross bar are provided with connecting pipes extending to both ends of the mine car. When docking between the mine cars, the end of the screw rod is aligned with the screw tube at the end of the connecting pipe and screwed in. After the docking of the mine cars is completed, the screw rod is screwed in the opposite direction to screw the other end of the screw rod into the screw tube at the end of the adjacent mine car, thereby realizing the connection of the braking systems between the mine cars, facilitating the synchronous braking movement of each section of the mine car.

[0008] Furthermore, a triangular block is movably connected to the top of the sleeve via a spring, and the inclined surface of the triangular block corresponds to the inclined surface of the trapezoidal block; the triangular block is squeezed and displaced by the movement of the inclined surface of the trapezoidal block.

[0009] Furthermore, a connecting rod penetrating the spring and the inside of the sleeve is welded on the surface of the triangular block and connected to the brake plate through the connecting rod. A brake pad is detachably connected to the bottom of the brake plate. The spring can drive the brake plate to reset after the braking action is completed, and the brake pad can be quickly replaced.

[0010] Furthermore, both ends of the connecting pipe are welded with screw tubes for easy docking with the screw rod; the screw tube structure facilitates docking with the screw rod to achieve connection between the mine cars.

[0011] Compared with the prior art, the utility model has the following beneficial effects: a crossbar and a sleeve are installed near the track at the bottom of the mine car, and the end of the crossbar near the tractor is connected to the power end of the hydraulic motion component inside the tractor. After the mine cars are docked, the crossbars are connected by screws. Under normal use, the trapezoidal block is away from the triangular block, and the brake pad is away from the track. When the brake is in action, in addition to the operation of the disc brake at the bottom of the mine car, the crossbar moves horizontally under the action of the tractor hydraulic component, the trapezoidal block squeezes the triangular block compression spring, and the connecting rod drives the brake plate and brake pad to move so that the brake The plate fits the track surface to increase friction resistance for braking, and cooperates with the disc brake to improve braking efficiency and expand the braking form. At the same time, the brake plate and brake pad are located close to the track side, which is easy to replace and does not require lifting the mine car; both ends of the cross bar are provided with connecting pipes extending to both ends of the mine car. When docking between mine cars, align the end of the screw with the screw tube at the end of the connecting pipe and screw it in. After the mine cars are docked, the screw is turned in the opposite direction to screw the other end of the screw into the screw tube at the end of the adjacent mine car, thereby realizing the connection between the brake systems of the mine cars, which is convenient for the synchronous braking movement of each section of the mine car.
