Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration, in particular to a drilling positioning device for core sampling. Background Art

[0002] In geological exploration, core sampling is an important means of obtaining underground rock information. When performing core sampling, a core sampling drill is required. At present, most of the mainstream core sampling drills on the market use a lower flat plate structure for support and positioning. In some complex terrains and harsh environments, traditional core sampling drills cannot be placed stably, affecting the accuracy of the drilling position. Workers are required to use pads to level the uneven position to ensure normal drilling work.

[0003] To this end, we propose a core sampling drilling positioning device that can provide stable support for the core sampling drill and ensure the precise drilling position. Utility Model Content

[0004] In order to overcome the shortcomings of existing core sampling drills that cannot adapt to complex terrain and affect the positioning of drilling holes, the utility model provides a core sampling drilling positioning device that can provide stable support for the core sampling drill and ensure the accurate drilling position.

[0005] A drilling positioning device for core sampling comprises a base frame, the base frame is fixedly connected with a laterally symmetrically arranged rounded corner plate, the base frame is fixedly connected with a laterally symmetrically arranged handle, four threaded caps are fixedly connected to the base frame, long threaded rods are threadedly connected in the threaded caps, a guide frame is fixedly connected to the bottom end of the base frame, a slider is slidably connected in the guide frame, a fine threaded rod is threadedly connected in the slider, positioning rings are rotatably connected between the fine threaded rods, the positioning rings are fixedly connected with limit rods which are symmetrically arranged in the longitudinal direction, and the limit rods are slidably connected to adjacent sliders.

[0006] As a preferred technical solution of the utility model, the bottom end of the long threaded rod is a spherical structure, which is used for contacting the ground for support.

[0007] As a preferred technical solution of the utility model, it also includes equidistantly distributed round-headed rods, which are slidably connected to the sliders, and a reset spring is connected between the round-headed rods and the adjacent sliders.

[0008] As a preferred technical solution of the utility model, holes and grooves are equidistantly distributed in the guide frame, and the round-headed rods are inserted into adjacent holes and grooves.

[0009] As a preferred technical solution of the utility model, it also includes a longitudinally symmetrically arranged connecting seat, which is fixedly connected to the base frame, and a sliding plate is slidably connected between the longitudinally symmetrically arranged connecting seats. The base frame is fixedly connected to four support plates, and the support plates clamp the sliding plate inside for support.

[0010] As a preferred technical solution of the present invention, the support plate is made of elastic material.

[0011] The utility model has the following advantages: 1. The core sampling drill is placed on a rounded plate, and the base frame is supported to a horizontal state by rotating the long threaded rod, thereby providing stable support for the core sampling drill, and then the positioning ring is controlled to move forward, backward, left and right to adjust the position. After adjustment, the core sampling drill can pass through the positioning ring for precise positioning and sampling.

[0020] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0021] Embodiment 1: A drilling positioning device for core sampling, such as Figure 1-Figure 4 As shown, it includes a base frame 1, a rounded plate 2, a handle 3, a long threaded rod 4, a threaded cap 5, a guide frame 6, a positioning ring 7, a slider 8, a fine threaded rod 9 and a limit rod 10. The left and right parts of the base frame 1 are fixedly connected with the rounded plate 2, the front and rear sides of the base frame 1 are fixedly connected with the left and right symmetrical handles 3, the left and right parts of the base frame 1 are fixedly connected with the front and rear symmetrical threaded caps 5, the long threaded rod 4 is threadedly connected in the threaded caps 5, the lower end of the long threaded rod 4 is a spherical structure, the front and rear parts of the lower side of the base frame 1 are fixedly connected with the guide frame 6, the slider 8 is slidably connected in the guide frame 6, the fine threaded rod 9 is threadedly connected in the slider 8, the front and rear fine threaded rods 9 are rotatably connected with the positioning ring 7, the front and rear sides of the positioning ring 7 are fixedly connected with two limit rods 10, and the limit rod 10 is slidably connected to the adjacent slider 8.

[0022] When using the device, the staff will move the device to a suitable position through the handle 3, and then place the core sampling drill on the rounded corner plate 2. After placing it, the staff will rotate the long threaded rod 4. Under the action of the threaded cap 5, the long threaded rod 4 will move up and down to adjust the position while rotating, ensuring that the four long threaded rods 4 are in contact with the ground to support the base frame 1 to a horizontal state, thereby providing stable support for the core sampling drill. After leveling, the staff will push the slider 8 to slide left and right in the guide frame 6, and then drive the positioning ring 7 to move left and right through the limit rod 10, and then drive the positioning ring 7 to move forward and backward to adjust the position through the rotation of the fine threaded rod 9. After the position adjustment of the positioning ring 7 is completed, the core sampling drill can pass through the positioning ring 7 for precise positioning and sampling.

[0023] Embodiment 2: Based on embodiment 1, Figure 4 and Figure 5 As shown, it also includes a round-headed rod 11 and a reset spring 12. Four equidistantly distributed round-headed rods 11 are slidably connected to the upper and lower sides of the slider 8. Equidistantly distributed holes and grooves are opened on the upper and lower sides of the guide frame 6. The round-headed rods 11 are inserted into adjacent holes and grooves. A reset spring 12 is connected between the round-headed rods 11 and the adjacent sliders 8.

[0024] When the device is used, when the slider 8 slides left and right in the guide frame 6, the round head rod 11 will also be squeezed and compressed into the slider 8 by the guide frame 6, and the reset spring 12 will be deformed. When the slider 8 slides to a suitable position, under the action of the reset spring 12, the round head rod 11 slides outward and is stuck in the hole groove, thereby fixing the position of the slider 8.

[0025] like Figure 1 and Figure 6As shown, it also includes a connecting seat 13, a sliding plate 14 and a support plate 15. The left and right parts of the base frame 1 are fixedly connected with the front and rear symmetrical connecting seats 13, and the sliding plate 14 is slidably connected between the front and rear connecting seats 13. The left and right parts of the base frame 1 are fixedly connected with four support plates 15. The support plates 15 are made of elastic material, and the support plates 15 clamp the sliding plates 14 inside for support.

[0026] When drilling and sampling is performed, the sliding plate 14 can shield and protect the interior of the device to prevent gravel and dust from splashing, and under the clamping action of the support plate 15, the sliding plate 14 can slide up and down to adjust the position to ensure the protective effect.
