Description

Technical Field

[0001] This utility model relates to the field of drilling rig fluid supply technology, specifically a remote fluid supply device for drilling rigs used in coal mines to prevent rockburst. Background Technology

[0002] Rockburst refers to the sudden and violent destruction of rock masses surrounding mine shafts or working faces due to the instantaneous release of elastic deformation energy. It is often accompanied by phenomena such as coal and rock ejection, loud noises, and blast waves. Currently, rockburst is typically prevented by drilling holes in the ground using anti-rockburst drilling rigs.

[0003] The construction of rockburst prevention and control projects in mining faces requires a large number of drilling rigs, each with its own fluid supply. These rigs also need to be moved and their pump boxes switched on and off continuously according to the construction progress. Due to the long length of the pipelines connecting the fluid supply equipment and the drilling rigs, the pipelines are quite heavy. Furthermore, the drilling rigs are not arranged in a straight line. In order to reduce the bending force at the connection between the pipelines and the fluid supply equipment and to avoid damage to the joints, the fluid supply equipment needs to be adjusted to form a straight line between the pipelines and the fluid supply equipment interface, which increases the workload. Utility Model Content

[0004] The purpose of this utility model is to provide a remote fluid supply device for drilling rigs used in coal mines to prevent rock bursts. The device can adjust the interface of the fluid supply equipment to reduce the workload, and can connect multiple drilling rigs in parallel to meet the needs of each drilling rig with different power in the roadway.

[0005] To achieve the above objectives, a remote fluid supply device for coal mine rockburst prevention drilling rigs is provided, comprising an oil supply pump station. A base is fixedly connected to the lower end of the oil supply pump station. The oil supply pump station is equipped with an oil supply nozzle and an oil return nozzle, both located on the same side. The oil supply nozzle is connected to a connecting mechanism, and the output end of the connecting mechanism is connected to several oil supply pipes. The oil return nozzle is connected to a return pipe. A support base is fixedly connected to the upper end of the base, located on the side of the oil supply nozzle and return nozzle of the oil supply pump station. Several T-pipes are fixedly connected to the upper end of the support base, and these T-pipes are vertically stacked on the support base. Each T-pipe has an oil supply interface, an equipment interface, and a branch pipe interface on its surface. The end of the oil supply pipe furthest from the connecting mechanism is connected to the oil supply interface, and the branch pipe interface is connected to an oil supply branch pipe. The upper end of the T-pipe... An upper connecting plate is fixedly connected to the middle of the end of the tee pipe, and a lower connecting plate is fixedly connected to the lower end of the tee pipe. The shape of the lower connecting plate is the same as that of the upper connecting plate. The upper and lower connecting plates of two adjacent tee pipes are in contact. Two U-shaped mounting plates are symmetrically fixedly connected to the outer ends of the upper connecting plate, and the openings of the two mounting plates are opposite each other. The outer end of the lower connecting plate of the upper tee pipe is located in the mounting plate. A locking block is slidably connected inside the mounting plate, and the distance between the lower end of the locking block and the bottom of the opening of the mounting plate is greater than the sum of the thicknesses of the upper and lower connecting plates. A locking bolt is provided in the middle of the upper end of the mounting plate, and the lower end of the locking bolt passes through the mounting plate and is threadedly connected to the mounting plate. The lower end of the locking bolt extends to the middle of the upper end of the locking block, and the lower end of the locking bolt is rotatably connected to the locking block. It can adjust the interface of the fluid supply equipment to reduce the workload, and connect the fluid supply equipment to multiple drilling rigs in parallel to meet the needs of each drilling rig with different power in the roadway.

[0006] According to the aforementioned remote fluid supply device for coal mine rockburst prevention drilling rigs, the connecting mechanism consists of several T-connectors, which are sequentially connected. The nearest interface of each T-connector to the oil supply pump station is connected to an oil supply nozzle. An end cap is installed at the farthest end of each T-connector from the oil supply pump station, and the end cap is connected to a flange on the T-connector. The interfaces of each T-connector are respectively connected to an oil supply pipe. The T-connectors are used to connect multiple drilling rigs, and the number of T-connectors can be increased or decreased according to the number of drilling rigs.

[0007] According to the aforementioned remote fluid supply device for a coal mine rockburst prevention drilling rig, a high-pressure regulating valve is installed in each of the several three-way pipes, and the high-pressure regulating valve is located at the connection end between the three-way pipe and the oil supply pipe. The high-pressure regulating valve is used to regulate the liquid pressure in the oil supply pipe.

[0008] According to the aforementioned remote fluid supply device for a coal mine rockburst prevention drilling rig, the lower ends of the upper and lower connecting plates are respectively provided with a plurality of connecting holes at equal intervals. The connection holes allow the tee pipe to be fixed with bolts when no angle adjustment is required or when adjusting to a specific angle, thus improving the applicability of the device.

[0009] According to the aforementioned remote fluid supply device for a coal mine rockburst prevention drilling rig, the lower end of the locking block is provided with anti-slip protrusions, and the lower end of the locking block is coated with a wear-resistant coating. The anti-slip protrusions increase the friction at the bottom of the locking block, and the wear-resistant coating improves the wear resistance of the bottom of the locking block and extends its service life.

[0012] 1. Multiple T-pipes are combined using the upper and lower connecting plates. The locking bolts push the locking blocks to fix the upper and lower connecting plates, which facilitates the adjustment of the orientation of the T-pipes connected to the drilling rig and reduces the workload.

[0013] 2. Several T-pipes form a connection mechanism and are connected to several T-pipes through oil supply pipes, so that the drilling equipment is connected in parallel to avoid affecting the prevention and control of rockburst when one of the drilling rigs is damaged.
