Description

Technical Field

[0001] The invention relates to the technical field of drilling rig fixing devices, and in particular to a drilling rig stabilizing device for coal mine tunnel support. Background Art

[0002] The drilling rig stabilization device for coal mine tunnel support is an important innovation in the field of coal mining technology. Its background technology is derived from a deep understanding of the need for drilling rig stability during coal mine tunnel excavation and support. In coal mine tunnel construction, the surrounding rock conditions are complex and changeable, which places high demands on the stability of the drilling rig. Traditional drilling rig stabilization methods are often difficult to adapt to complex geological conditions, resulting in problems such as low drilling accuracy and low construction efficiency. Through innovative design, this device achieves effective stabilization of the drilling rig, improves drilling accuracy and construction efficiency, provides a strong guarantee for the rapid excavation and support of coal mine tunnels, and promotes the further development of coal mining technology.

[0003] After searching, the Chinese patent number CN118346185A discloses a drilling rig stabilization device for coal mine tunnel support, including a drilling rig car plate, support legs, a connecting box, a sliding box, and an auxiliary support assembly. A first hydraulic cylinder is vertically fixed at both ends of one side of the upper part of the drilling rig car plate, and a second hydraulic cylinder is vertically fixed at both ends of the other side of the upper part of the drilling rig car plate, and the lower ends of the first hydraulic cylinder and the second hydraulic cylinder pass through the lower outer wall of the drilling rig car plate, and the output ends of the first hydraulic cylinder and the second hydraulic cylinder are fixed with supporting legs, a connecting box is fixed at the upper part of the drilling rig car plate near the positions of the two first hydraulic cylinders, and the lower end of the connecting box passes through the bottom of the drilling rig car plate, and the lower part of the connecting box is an open structure, and a sliding box is slidably inserted at one end of the opening of the connecting box, and an auxiliary support assembly is arranged in the sliding box. The drilling rig stabilizing device for supporting coal mine tunnels of the present invention can improve the stability of the drilling rig when drilling. Compared with the prior art, the Chinese patent number CN118346185A solves the problem that the existing supporting device only has four vertical supports at the foot points. However, the drilling direction of the usual drilling rig is horizontal operation, which makes one end of the drilling rig car body tilt and warp when the drilling rig is operating, and the ordinary corner point support cannot provide a stable support effect.

[0004] However, in actual use of the above-mentioned device, when the drill rig is working in a coal mine tunnel, under different ground environments of the mine tunnel, the existing supporting device is difficult to adjust accordingly according to the unevenness of the road surface of the mine tunnel, which makes it difficult for the drill rig to remain level during work. In addition, a large amount of dust will be generated during the drilling process, causing harm to the workers. Therefore, a drill rig stabilization device for coal mine tunnel support is proposed. Summary of the invention

[0008] The fifth gear is rotatably connected to the adjusting shell, and the fifth gear is meshed with the second rack. The second rack is fixedly connected to a mounting plate on a side away from the fifth gear. The mounting plate is slidably connected to the storage bin, and the storage bin is fixedly connected to one side of the adjusting shell, and a dust suction mechanism is fixedly connected to a side of the mounting plate away from the second rack. When the third motor is started, the fifth gear is driven to rotate at the same time, and the rotation of the fifth gear drives the second rack to move.
