Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction equipment, in particular to a drilling inclination measuring device suitable for a rotary drilling rig. Background Art

[0002] At present, rotary drilling rigs are widely used in the field of construction engineering. Their technical characteristics are the use of multiple short-distance drilling for large-diameter long pile holes, which can serve foundation treatment, water-stop curtains and foundation pit support projects. High verticality piles are the prerequisite for ensuring construction quality. Drilling and pile foundation projects with poor verticality will cause serious economic losses and even threaten project safety. At the same time, as urban construction develops deep underground, the requirements for pile depth and pile verticality are getting higher and higher.

[0003] At present, a large number of rotary drilling rigs are not equipped with corresponding control devices for the verticality of the borehole. Some equipment uses equipment or methods such as plumb line, visual inspection, theodolite, laser rangefinder, etc. to monitor the verticality of the borehole. The above control methods have many disadvantages. For example, the plumb line method and visual inspection method have low accuracy, poor effect, and high subjectivity of operators. Although equipment such as theodolite and laser rangefinder have improved the accuracy, their detection principle is to infer the verticality of the drill rod below the ground by observing the verticality of the mast or drill rod above the ground. This method is an indirect measurement and has low accuracy.

[0004] After searching, a patent publication number CN114412450B is found, which is a device for measuring inclination while drilling suitable for a rotary drilling rig. The device for measuring inclination while drilling of the rotary drilling rig includes a main body, a drill rod assembly, a lifter, a lifting rope and a first sensor. The drill rod assembly is erected on the main body, and a drill bit is arranged at the bottom of the drill rod assembly. Although the device can solve the technical problems existing in the prior art, it still has certain disadvantages when used. The right side of the device body is heavier than the left side, and the left side of the body lacks a corresponding counterweight support mechanism, which makes the device easy to tilt up during actual work and has poor working stability. Utility Model Content

Hand wheels are fixedly mounted on the top ends of the two groups of support screws, and supports are fixedly connected to the bottom ends of the two groups of support screws. The counterweight mechanism includes an L-shaped fixing plate, which is fixedly connected to the front end of the device body, and two groups of columns are symmetrically fixedly connected on the L-shaped fixing plate, and multiple groups of counterweight plates are stacked on the two groups of columns.

[0013] The invention relates to a drilling inclinometer device suitable for a rotary drilling rig. When in use, an adjusting screw rod is driven to rotate by a motor, so that the adjusting screw rod drives a transmission sleeve to slide downward along a guide rod. When the transmission sleeve slides downward, the transmission sleeve pushes the sliding rod to slide outward through the connecting strip plate, so that the sliding rod pushes the connecting plate to move outward, thereby expanding the support range. After reaching the appropriate support range, the supporting screw rod is rotated by a hand wheel to move the supporting screw rod downward, and the supporting screw rod drives the support to move downward until the support supports the ground. By widening the support range, the supporting effect can be enhanced and the equipment support can be stable. A plurality of counterweight plates are mounted on the column, and the number of counterweight plates can be increased according to actual conditions to increase the counterweight and avoid the device from tilting during work, thereby effectively avoiding the device from tilting in actual work and improving the working stability.
