Real-time measuring device and method for residual ruler of drilling machine

Abstract

The invention provides a real-time measuring device and method for an on-board residual ruler of a drilling machine. The device comprises a separated ultrasonic distance measurement module and a short-side distance measurement module, and the separated ultrasonic distance measurement module comprises an ultrasonic transmitting unit fixed at the top end of a driving drilling rod, and an ultrasonic receiving unit fixed on a support. The short-side distance measuring module is used for measuring the vertical distance between the ultrasonic receiving unit and a vertical shaft of the drilling machine; the short-side distance measuring module is an integrated ultrasonic distance measuring device, and the integrated ultrasonic distance measuring device and the ultrasonic receiving unit are fixed into a whole. According to the real-time measuring device, the drilling hole depth can be obtained in real time, the traditional inherent thought of directly detecting the hole depth is broken through, real-time measurement is achieved, and the drilling process can be completely recorded; and the ultrasonic distance measuring device is independent of the drilling machine, influence of vibration on the measuring device in the drilling process of the drilling machine is avoided, and distance measuring accuracy and equipment stability are guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of measuring the remaining ruler on the drilling rig, and in particular to a real-time measuring device and method for the remaining ruler on the drilling rig. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Engineering drilling rigs are mainly used for foundation survey, and vertical shaft rotary core drilling rigs are mostly used, such as XY-1(A), XY-2, HZ-130 (150 and 180), etc., which are convenient for disassembly and transportation, and occupy less land. The drilling depth of this equipment is mainly based on the manual calculation and judgment of the drilling tool and the start-stop drilling. The active drill pipe has a scale every 10cm. Theoretically, the steel ruler can be used to measure the depth. However, in the actual operation, no captain will do th...

Problems solved by technology

[0005] At present, the inventors can realize real-time measurement of hole depth devices, mostly using digital drilling rigs, but this type of drilling rig is mainly used in large deep hole drilling such as oil exploration. Due to its large size, this type of drilling rig cannot be used for basic exploration holes Engineering drilling rigs with relatively small depth; in addition, digital drilling rigs need to install probes at the drill bit to achieve detection; this detection method has the following disadvantages:

[0006] (1) There is a probe at the drill bit. Due to the complex geological environment, various bad geological conditions will be encountered during the drilling process, so the probe is easily damaged;

[0007] (2) The drill bit of the digital drilling rig needs to use special magnetic materials, which is expensive and expensive;

[0008] (3) As a complete set of equipment, the digital drilling rig cannot use the existing simple drilling rig, which is a waste of the existing drilling rig;

[0009] (4) The wires connected to the probes need to be threaded through the drill pipe. During the drilling process, the wires need to be combed and adjusted every time. The construction is very inconvenient and the work efficiency is very low;

[0010] (5) The vibration of the drilling rig during the drilling process is not conducive to data collection
