Description

Technical Field

[0001] The utility model relates to the technical field of rotary drilling rigs, in particular to a dust-proof device for a rotary drilling rig. Background Technique

[0002] A rotary drilling rig is a construction machine suitable for hole-forming operations in building foundation projects. It is mainly suitable for construction in soil layers such as sandy soil, cohesive soil, and silty soil. It is widely used in various foundation construction projects such as cast-in-place piles, diaphragm walls, and foundation reinforcement. The rated power of a rotary drilling rig is generally 125 - 450 kW, the power output torque is 120 - 400 kN·m, the maximum hole-forming diameter can reach 1.5 - 4 m, and the maximum hole-forming depth is 60 - 90 m, which can meet the requirements of various large-scale foundation constructions. However, when the drilling rig is working, the drill bit drills into the ground, which will cause a large amount of dust to fly up, and the dust scatters everywhere. If not treated, it will pollute the air and affect the health of the staff.

[0003] In the prior art, in the technical solution recorded in the patent application with the application number CN201922318811.7 and the application name of a dust-proof device for the power head construction of a rotary drilling rig, it includes a drilling rig body. A drill pipe is provided on the drilling rig body. Two pairs of fixing rods are installed at the upper end of the drilling rig body. A bearing plate is installed on the two pairs of fixing rods. Two pairs of through holes sleeved on the fixing rods are opened on the bearing plate. Two pairs of buffer springs are sleeved on the two pairs of fixing rods. The utility model relates to the technical field of rotary drilling rigs. The structure of the utility model is simple. The dust can be sucked into the dust collection box by the cooperation of a blower and a dust collection cover, and the dust can be dust-removed by the cooperation of an atomizing nozzle connected to a water tank and then fall into the collection box below. It can be quickly taken out and cleaned through a sliding door. At the same time, since the drilling rig will generate vibrations during operation, the setting of buffer springs and return springs can effectively absorb the vibrations and avoid damage to the dust suction components above the bearing plate caused by vibrations, which brings convenience to people's use.

[0004] However, there are still some deficiencies in the process of use. It is not convenient for installation and disassembly during use, has a small adaptation range, and is not convenient for adjusting the height and angle at the same time, with poor flexibility. Therefore, we make further improvements to it. Summary of the Invention
