Description

Technical Field

[0001] The utility model relates to the technical field of concrete drilling, in particular to a multi-station concrete drilling machine. Background Art

[0002] A concrete drilling machine is a professional mechanical device, mainly used for drilling holes in concrete structures. Concrete drilling machines are often used for core sampling of cement concrete, asphalt concrete, and limestone foundations in places such as highways, airports, ports, and dams to conduct compressive and flexural tests, which helps to evaluate the quality and performance of concrete.

[0003] After retrieval, a Chinese utility model patent with the publication number CN219213649U, named a multi-station concrete drilling machine, includes: a drilling base platform, in the middle of which a rectangular installation cavity is provided; the rectangular installation cavity penetrates the upper and lower sides of the drilling base platform, and a plurality of drilling stations are arranged inside the rectangular installation cavity; a rear support column, slidably arranged on the rear side of the rear support column, and capable of providing ground support for the rear side of the drilling base platform; the drilling base platform can move vertically up and down relative to the rear support column; a drilling mechanism is arranged at each drilling station. The structure in this solution can achieve multi-station synchronous drilling through the multiple drilling mechanisms arranged on the drilling base platform, effectively improving the drilling speed.

[0004] However, it is found during use that the position adjustment range of the drilling mechanism is limited. When it is necessary to adjust the distance between two adjacent drilling mechanisms, due to design limitations, the adjustable range is often relatively limited. This limitation is particularly prominent when multiple stations need to be constructed simultaneously because different construction requirements may require different drilling spacings, and the limited adjustment range may not be able to meet these diverse needs. When drilling a large area of concrete, the limited drilling spacing may limit the drilling coverage and efficiency, and too close drilling spacing may also increase the risk of concrete damage during drilling, affecting the drilling quality and construction effect, and being unfavorable for the use of concrete drilling. Summary of the Utility Model

[0005] In view of the deficiencies of the prior art, the present utility model provides a multi-station concrete drilling machine for construction, which solves the technical problems that the position adjustment range of the drilling mechanism is limited. When it is necessary to adjust the distance between two adjacent drilling mechanisms, due to design limitations, the adjustable range is often relatively limited. This limitation is particularly prominent when multiple stations need to carry out construction simultaneously, because different construction requirements may require different drilling spacings, and the limited adjustment range may not be able to meet these diverse needs. When it is necessary to drill a large area of concrete, the limited drilling spacing may limit the coverage range and efficiency of drilling. An overly close drilling spacing may also increase the risk of concrete damage during drilling, affecting the drilling quality and construction effect, and being unfavorable for the use of concrete drilling.

The push block is threadedly connected to the lead screw through a threaded hole. On the outer walls of the support blocks at both ends, a first servo motor is installed through a mounting seat. The output shaft of the first servo motor is coaxially connected to the lead screw.

[0008] Through the above technical solutions, the output shaft of the first servo motor drives the lead screw to rotate along the support block respectively, pushing the push block to slide along the frame, and the push block drives the L-shaped moving block to slide along the guide rail and the top surface of the frame.

[0009] Preferably, the moving mechanism includes a guide rail. The outer wall of the guide rail is fixedly connected to the outer wall of the frame.

A first air cylinder is installed on the top surface of the guide rail through a mounting seat. The bottom surface of the piston rod of the first air cylinder is fixedly connected to the top surface of the movable block.

[0010] Through the above technical solutions, when the piston rod of the first air cylinder contracts, the movable block moves upward along the guide rail, so that the bottom surface of the electric drive wheel is located above the bottom surface of the frame. At this time, the bottom surface of the frame is in frictional contact with the top surface of the concrete to be drilled.

[0011] Preferably, a second cylinder is installed on the top surface of the pushing block through a mounting seat, and the piston rod of the second cylinder is fixedly connected to the side wall of the sliding block.

[0012] Through the above technical solution, the piston rod of the second cylinder pushes the sliding block to move along the L-shaped moving block to a suitable position.

[0013] Preferably, a limiting groove is formed on the sliding block, the drilling assembly includes a limiting block, the limiting block is slidably connected to the sliding block through the limiting groove, a rack is fixedly connected to the rear wall of the limiting block, a gear is meshed with the rear wall of the rack, and a second servo motor is installed on the top surface of the sliding block through a mounting seat.

[0014] Preferably, a rotating shaft is coaxially connected to the output shaft of the second servo motor, the middle of the gear is sleeved on the middle of the rotating shaft, and two brackets are rotatably connected to the rotating shaft in a symmetrical structure, and the bottom surface of the bracket is fixedly connected to the top surface of the sliding block.
