Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a device for automatically calculating the drilling depth of drilling equipment. Background Art

[0002] In geotechnical engineering investigation, drilling is currently one of the most intuitive ways to obtain site geological data. Accurately measuring borehole depth is crucial for drilling quality control, directly impacting the accurate demarcation of various rock and soil strata. Drilling depth is typically determined manually by measuring the cumulative length of drill rod below the hole mouth with a tape measure. However, in practice, drilling teams, to expedite progress, often rely solely on visually estimating the borehole depth based on the drill rig's vertical axis scale and the number of drill rods. This leads to arbitrary placement of drill core, inevitably resulting in significant errors in formation depth.

[0003] Currently, most drilling depths are still measured by survey engineers using a tape measure to measure and calculate the drill rod removed from the hole. While this method is simple and intuitive, it still presents several issues: Dedicated personnel must monitor the entire process and perform manual calculations for each pass, making the process cumbersome and inefficient. The minimum measurement length is limited by the length of the drill rod, making it impossible to determine the hole depth at any time. This process is time-consuming and subject to significant errors due to human factors. To reduce the error rate, multiple people are required to count and monitor the process simultaneously, which wastes significant human resources, increases management costs, and fails to eliminate large errors in drilling depth.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A device for automatically calculating the drilling depth of drilling equipment includes a base, a clamp and a depth calculation assembly, the clamp being connected to the base and used to be installed on the top of the drilling rig casing, the depth calculation assembly including a meter and a drive wheel, the meter being movably arranged on the base through a guide assembly, the meter being provided with a transmission shaft, the drive wheel being arranged on the transmission shaft of the meter and being located above or below the clamp, the drive wheel being rotated when the drill rod moves to calculate the drilling depth of the drill rod through the meter, the guide assembly being provided with an elastic member, the elastic member being used to keep the drive wheel in contact with the drill rod.

[0007] Furthermore, there are two groups of guide assemblies, and the two groups of guide assemblies are arranged at intervals on the base. Each guide assembly includes a guide column, a support seat and a slider. There are two support columns, which are respectively arranged at both ends of the base. The guide column is arranged between the two support seats. The slider is slidably arranged on the two guide columns, and the meter is arranged on the slider.

[0008] Furthermore, the elastic member includes a spring, one end of the spring abuts against the slider, and the other end abuts against the support seat, and the driving wheel maintains abutment against the drill rod through the elastic force of the spring.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention. Example 1

[0027] like Figures 1 to 3 As shown, this embodiment provides a device for automatically calculating the drilling depth of drilling equipment, including a base 1, a clamp 2, and a depth calculation assembly 3. The clamp 2 is connected to the base 1 and is used to be installed on the top of the drilling rig casing. The clamp 2 fixes the entire device to the drilling rig casing to ensure the stability of the device during the drilling process.

[0028] The depth calculation assembly 3 includes a meter 31 and a drive wheel 32. The meter 31 is movably mounted on the base 1 via a guide assembly 5. Specifically, two sets of guide assemblies 5 are provided, spaced apart on the base 1. Each set includes a guide post 51, a support base 52, and a slider 53. Two support bases 52 are provided, one at each end of the base 1. The guide post 51 is positioned between the two support bases 52. The slider 53 slides on the two guide posts 51, and the meter 31 is mounted on the slider 53. This structure allows the meter 31 to move stably on the base 1 while maintaining its measurement accuracy.

[0029] The meter meter 31 has a transmission shaft 311, and a drive wheel 32 is disposed on the transmission shaft 311 of the meter meter 31 and is located above or below the clamp 2. In this embodiment, the drive wheel 32 is located above the clamp 2. When the drill rod moves, the drive wheel 32 rotates, and the rotation is transmitted to the meter meter 31 via the transmission shaft 311, thereby calculating the drilling depth of the drill rod.

[0030] To ensure that drive wheel 32 maintains contact with the drill rod, guide assembly 5 is provided with an elastic member 7. Specifically, elastic member 7 comprises a spring, one end of which abuts slider 53 and the other end abuts support base 52. The spring's elastic force ensures that drive wheel 32 maintains close contact with the drill rod, ensuring accurate and consistent measurement.

[0031] Furthermore, to enhance measurement stability and accuracy, two drive wheels 32 are provided. These two drive wheels 32 are spaced axially along the transmission shaft 311 of the meter 31, and both drive wheels 32 abut against the drill rod. This ensures that even if the drill rod deviates slightly during movement, at least one drive wheel 32 remains in contact with it, thus ensuring measurement continuity and accuracy.

[0032] In addition, in order to facilitate reading the drilling depth of the drill rod, a reading area 312 for displaying the drilling rod depth is provided on the meter 31. The reading area 312 can be a digital display or a dial that can display the drilling depth of the drill rod in real time, making it convenient for the operator to grasp the drilling progress at any time. Example 2

[0033] Based on Example 1, this embodiment further optimizes the depth calculation component 3. Figure 2 As shown, two depth calculation assemblies 3 are provided, and the two depth calculation assemblies 3 are spaced apart and arranged on the guide assembly 5, and the drill rod is located between the two sets of drive wheels 32. This structure can further improve the accuracy and stability of the measurement, because the two sets of depth calculation assemblies 3 can measure the drilling depth of the drill rod simultaneously, thereby reducing the error that may be caused by a single measurement assembly. Example 3

[0034] Based on Example 1 or Example 2, this embodiment further optimizes the clamp 2. Figure 1 As shown, the clamp 2 is provided with a fastening assembly 8 for securing the clamp 2 to the drill casing. The fastening assembly 8 comprises multiple threaded seats 81 and fixing screws 82 circumferentially arranged on the outer wall of the clamp 2. Each threaded seat 81 is threadedly connected to a fixing screw 82. The fixing screws 82 are used to abut against the drill casing after the clamp 2 is placed on top of the drill casing to secure the clamp 2. This structure ensures a tight connection between the clamp 2 and the drill casing, preventing the device from loosening or falling off during drilling, thereby ensuring accurate and safe measurements.

[0035] Working principle:

[0036] Place the device on the drilling rig to the designated drilling position, install the clamp 2 on the top of the drilling rig casing, tighten the fixing screw 82 to fix the calculation device to prevent sliding, then connect the core tube to the drill rod, use the drill rig lifter to lower the core tube and drill rod into the casing, and then drill normally. At the end of the drilling round, before lifting the drill rod, clamp the drive wheel 32 with the drill rod and the core tube to ensure that the drive wheel 32 in the device is in close rolling cooperation with the drilled drill rod, and at the same time adjust the meter meter 31 reading to zero, and then use the drill rig lifter to lift the drill rod. The drill rod drives the drive wheel 32 to rotate at the same time, further drives the meter meter 31 to count automatically, reads the counting device reading, and calculates the drilling depth.

[0037] In summary, the present invention provides an automatic drilling depth calculation device for drilling equipment. The device is secured to the drilling rig casing via a clamp, and a drive wheel abuts against the drill rod and rotates as the rod moves. The meter gauge calculates the rod's penetration depth. This device features a simple structure, easy operation, accurate measurement, and high stability. It can effectively improve drilling efficiency and quality, while reducing labor and management costs.

[0038] Obviously, the embodiments described are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art are within the scope of protection of the present invention.
