Description

Technical Field

[0001] This utility model belongs to the field of drilling rig technology, and in particular relates to an auxiliary measuring device for the drilling mast angle of a rotary drilling rig. Background Technology

[0002] Rotary drilling rigs are construction machines suitable for hole-forming operations in building foundation engineering. They are mainly suitable for construction in soil layers such as sand, cohesive soil, and silty soil, and are widely used in various foundation constructions such as cast-in-place piles, continuous walls, and foundation reinforcement.

[0003] Chinese patent CN215057162U discloses a mechanism for adjusting the angle of the mast of a rotary drilling rig. The patent describes "a mechanism for adjusting the angle of the mast of a rotary drilling rig, comprising a drilling rig body and a mast. A support device is fixedly connected to the top of the drilling rig body, and the support device is fixedly connected to the mast. A boom is connected to one side of the drilling rig body, and a U-shaped forearm is fixedly connected to the other end of the boom. A fixing plate and a driving device are arranged between the U-shaped forearms. An adjustment device is provided at one end of the mast, and the adjustment device and the support device are located at the mast..." On the same side of the mast, the adjustment device cooperates with the drive device. As a further embodiment of this invention: the support device includes a fixed block, one end of which is fixedly connected to the drilling rig body, and the other end of which is provided with a first rotating rod. A hydraulic cylinder is rotatably connected to the middle of the first rotating rod, and the first rotating rod slides in contact with the hydraulic cylinder. As a further embodiment of this invention: a telescopic rod is slidably connected to the other end of the hydraulic cylinder, and a connecting block is rotatably connected to the other end of the telescopic rod. A second rotating rod is provided at one end of the connecting block, and the telescopic rod is rotatably connected to the second rotating rod. The other end is rotatably connected to the drill mast. ... The beneficial effects of this utility model are: When the device is working, the main body of the drilling rig controls the lifting and lowering of the boom, which in turn drives the U-shaped boom to lift and lower, that is, the fixed plate lifts and lowers. Since the limit rod passes through the fixed plate, the limit rod only makes rotatable contact with the fixed plate. Therefore, when the fixed plate moves up and down, the fixed plate drives the limit rod to lift and lower, that is, the lower end of the drill mast lifts and lowers. Since the upper end of the drill mast is connected to a telescopic rod through a connecting block, when the lower end of the drill mast rises, the telescopic rod retracts into the hydraulic cylinder, causing the drill mast to gradually tend towards a horizontal state. When the lower end of the drill mast descends... The drill mast extends to bring it closer to a vertical position, and at the same time, the drive motor starts. The drive motor controls the rotation of the rotating shaft, that is, the rotation of the toothed shaft. The toothed shaft meshes with the toothed rod to rotate the turntable. The turntable drives the drill mast to rotate slightly around the limit rod as the center point for angle adjustment. The connecting block is rotatably connected to the drill mast, and the first rotating rod is slidably connected to the hydraulic cylinder. This ensures that the extension rod will not bend while the drill mast rotates slightly. This device can adjust the drill mast at multiple angles, which can reduce the error between the drilled hole and the required hole.

[0004] However, existing technology can only adjust the mast angle on flat slopes, lacking auxiliary measurement for the adjusted angle. Especially when the drilling rig is placed on inclined ground for drilling operations, it is difficult to calculate the angle between the drill mast hole and the horizontal plane. Therefore, it is necessary to design an auxiliary measurement device for the mast angle of rotary drilling rigs. Utility Model Content
