Description

Technical Field

[0001] The utility model belongs to the technical field of coal mining, and in particular relates to a water head drainage device across a belt at an excavation working face. Background Art

[0002] During coal mining, a tunnel is usually mined first to prepare for the mining face. The main functions are to explore coal, dig coal, explore water, and explore gas. A coal mining belt conveyor is usually installed inside, which is set on the same side as the air duct and water pipeline. When water is sprinkled in the tunnel to remove dust, the construction workers need to connect the water pipeline and work across the belt conveyor. The belt also discharges coal at irregular intervals, which brings safety hazards to the construction workers when crossing the belt to connect the water line. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a belt head drainage device across the excavation working face, including a belt conveyor and a water diversion rod. The frames on both sides of the belt conveyor are symmetrical and provided with support rods. The top of the support rod is provided with an annular casing. The water diversion rod is arranged through the casing. One end of the water diversion rod is provided with a quick-connect male head, and the other end of the water diversion rod is provided with a quick-connect female head. The pipe section of the water diversion rod located in the casing is provided with a stop valve, and the valve stem nut of the stop valve is provided through the casing. The stop valve is provided with a force rod, and one end of the force rod is fixed with a wrench hole matching the valve stem nut of the stop valve.

[0004] Furthermore, a chain is fixedly connected to the casing, and the other end of the chain is fixedly connected to the boosting rod. A hook that matches the wrench hole is provided on the support rod. The chain is used to connect the casing and the boosting rod, making it easy to use and take the boosting rod. The hook matches the wrench hole. When the boosting rod is idle, it can be hung on the hook through the wrench hole to prevent the boosting rod from shaking and causing collision and damage. It also prevents the boosting rod from falling on the belt conveyor and hindering the transportation of coal blocks.

[0005] Furthermore, the support rod includes a rod body and a hydraulic cylinder. The lower end of the rod body is fixedly connected to the telescopic rod of the hydraulic cylinder. The fixed end of the hydraulic cylinder is fixed with a pad, and the pad is connected to the two side frames of the belt conveyor by bolts. The hydraulic cylinder is used to facilitate the lifting and lowering of the rod body. Because the coal blocks on the belt conveyor are of different sizes and heights, in order to avoid larger coal blocks colliding with the water diversion rod when passing by, the support rod is set to an adjustable height support rod, which is suitable for use in various coal block sizes.

[0006] Furthermore, a sensor is provided in the middle of the water diverter rod, and the sensor and the hydraulic cylinder are connected to a controller through electrical signals. In order to enable the water diverter rod to automatically adjust the lifting height according to different coal block sizes, a sensor is set in the middle pipe section of the water diverter rod. The sensor is used to sense the height of the coal blocks close to the water diverter rod and send the sensed signal to the controller, which controls the hydraulic cylinder to rise.

[0007] Furthermore, a water head number is hung on the water diversion rod to distinguish the pipes of different water diversion rods.

[0008] The present invention also includes other devices or components that enable the tunneling working face cross-belt water head diversion device to function normally, which are conventional technical means in the field. In addition, the hydraulic cylinder and controller not specified in the present invention all adopt conventional technical means in the field.

[0009] The working principle of the utility model is that the quick-connect female connector is connected to the sprinkler pipe and the quick-connect male connector is connected to the water pipeline. The device is equipped with a force rod to facilitate the switching of the stop valve. The force rod is used to unscrew the valve stem nut of the stop valve to realize the water sprinkling and dust removal operation in the tunnel. The water guide rod, quick-connect female connector and quick-connect male connector used can also be used to recycle waste pipes and joints.

[0010] The beneficial effect of the utility model is that the device connects the left and right side pipes through the water guide rod installed on the belt conveyor, avoiding the construction workers from working across the belt conveyor when they need to connect the water pipeline, and solving the problem of safety hazards caused by the belt delivering coal to the construction workers at irregular intervals during the process of crossing the belt to connect the water line.
