Description

Technical Field

[0001] The utility model relates to geological exploration equipment, in particular to a core drilling rig power head fixing mechanism and a core drilling rig. Background Art

[0002] In geological exploration, core drilling rig is an important equipment that can obtain underground core samples through drilling for geological analysis and research.

[0003] Top-drive core drills are a common type of rig, whose core drill head follows a guide rail for drilling. To retrieve the core, a steel rope is typically used to connect the core drill to a winch, which then drives the core. This operation requires operators to move the core drill head away from the drilling position to facilitate core retrieval. This is especially labor-intensive when drilling oblique holes, as manual movement of the core drill head is required.

[0004] Several technical solutions have been proposed to address the problem of manually moving the power head. For example, hydraulic or mechanical drive methods are used to achieve lateral sliding motion of the power head through devices such as hydraulic cylinders or mechanical screws. While these solutions can reduce the labor intensity of workers to a certain extent, they still present the following challenges:

[0005] First, the structures of these mechanisms are relatively complex, and the manufacturing process is also relatively complicated, which leads to higher manufacturing costs;

[0006] Secondly, due to the heavy weight of these mechanisms, they may cause additional burden on the drilling rig during use, affecting its stability and service life;

[0007] In addition, the mechanism may wear out during use, which may result in the inability to compensate in time, affecting the quality and stability of the product's construction and making it more likely to cause equipment damage.

[0008] In addition, the drive mechanism of some side-sliding mechanisms is not arranged in the center, which will cause lateral force problems and affect the movement stability of the power head.

[0009] Therefore, it is necessary to solve the above technical problems. Summary of the Invention

[0010] In response to the above technical problems, the utility model provides a core drilling rig power head fixing mechanism and a core drilling rig. The fixing mechanism has a simple structure and is easy to implement, which not only reduces the weight but also controls the cost. The power head can slide up and down and sideways, with precise and stable movements and convenient operation, which greatly reduces the labor intensity of the staff.

[0011] In order to achieve the above purpose, the technical solution of the utility model is:

[0012] A core drilling rig power head fixing mechanism includes a power head, an upper and lower movable bracket, a side sliding bracket and a side sliding drive mechanism. The upper and lower movable bracket is provided with a cavity extending along the side sliding direction, the cavity accommodates the side sliding drive mechanism, the side sliding bracket is arranged on the front side of the cavity, and the power head is arranged on the side sliding bracket; the side sliding drive mechanism is respectively connected to the upper and lower movable bracket and the side sliding bracket and drives the side sliding bracket to slide back and forth relative to the upper and lower movable bracket.

[0013] The core drilling rig fixing mechanism is provided with a cavity to accommodate the side sliding drive mechanism, which can provide a better side sliding force effect for the side sliding bracket, not only saving space but also improving the stability of the side sliding.

[0014] In a further optimization, the vertically movable bracket includes a bracket body formed by bending a flat plate to form two raised portions, with the cavity formed between the two raised portions. The bracket body of the vertically movable bracket utilizes a flat plate structure that is bent multiple times, improving rigidity and strength. The central cavity facilitates the placement of the side-sliding drive mechanism, providing better side-sliding force absorption in the central portion.

[0015] A further optimized solution further includes two side sliding guide rails, one on each side of the cavity and connected to the vertically movable bracket, with both sides of the side sliding bracket located within the side sliding guide rails. The provision of side sliding guide rails on either side of the cavity of the vertically movable bracket facilitates the back-and-forth lateral movement of the side sliding bracket, ensuring smooth and stable side sliding and reliability during operation of the power head.

[0016] A further optimized solution further includes an up-and-down drive mechanism connected to the up-and-down movable bracket to drive it up and down. The up-and-down drive mechanism drives the up-and-down movable bracket to move up and down, and ultimately drives the power head up and down through the side-sliding bracket to meet the working requirements of different working conditions.

[0017] A further optimized solution also includes a frame, V-shaped guide rails, and V-shaped sliders. The V-shaped guide rails are opened outward on both sides of the frame, and the V-shaped sliders are provided on both sides of the vertically movable bracket to cooperate with the V-shaped guide rails. The V-shaped sliders on both sides of the vertically movable bracket fit in the V-shaped guide rails on both sides of the frame, enabling the vertically movable bracket to slide up and down, ensuring smooth up and down movement of the power head.

[0018] A further optimization scheme includes side panels on either side of the vertically movable brackets, each equipped with a plurality of adjustment screws connected to the V-shaped slider. The nut ends of the adjustment screws are threadedly connected to lock nuts. If the vertically movable brackets become loose or wear after a period of operation, the relative position between the V-shaped slider and the vertically movable brackets can be adjusted using the adjustment screws, and then locked in place using the lock nuts, ensuring that the V-shaped slider slides smoothly and securely on the V-shaped guide rail.

[0019] In a further optimized solution, the side-sliding drive mechanism is a side-sliding cylinder, the fixed end of which is connected to the vertical movable bracket, and the movable end of which is connected to the side-sliding bracket. By driving the side-sliding bracket through the side-sliding cylinder, precise control of the lateral sliding of the power head and convenient operation are achieved.

[0020] In a further optimized solution, the vertical drive mechanism comprises a vertically movable oil cylinder, the piston rod of which is hingedly positioned, and the vertically movable bracket is connected to the cylinder barrel of the vertically movable oil cylinder. The vertically movable oil cylinder drives the vertically movable bracket to achieve the up and down sliding of the power head, ensuring the smoothness and reliability of the up and down sliding.

[0021] A core drilling rig comprises any one of the core drilling rig power head fixing mechanisms described above.

[0022] Compared with the prior art, the present invention has the following technical advantages:

[0023] 1. Reduce labor intensity: The support body of the upper and lower movable bracket of the core drilling rig fixing mechanism adopts an upper and lower bent plate structure. The cavity is formed by multiple bendings, which can easily arrange the side sliding cylinder to realize the side sliding movement of the power head. In this way, when it is necessary to fish out the core or drill an oblique hole, there is no need to move the power head manually, which greatly reduces the labor intensity of the staff;

[0024] 2. Improved stability: The vertical movable bracket of the core drilling rig fixing mechanism has a simple structure and is lightweight. It also adopts a V-shaped slider structure that can fit in with the V-shaped guide rail on the frame to slide up and down. This structural design makes the vertical movable bracket run more smoothly without placing additional burden on the core drilling rig, thereby improving the stability and service life of the entire system.

[0025] 3. Reduce manufacturing costs: The upper and lower movable brackets of the core drilling rig's fixing mechanism adopt a multiple-bending structure, which improves rigidity and strength. At the same time, the cavity formed in the middle facilitates the arrangement of the side sliding cylinder. This structural design not only reduces manufacturing costs, but also facilitates maintenance and replacement of parts, further improving the economic efficiency of use.

[0026] 4. Good flexibility: The core drilling rig's fixed mechanism can adjust the relative position of the V-shaped slider and the upper and lower movable brackets by adjusting the screw. This allows for quick adjustment in the event of wear or other conditions to ensure the normal operation of the upper and lower movable brackets. The overall structure is not prone to shaking, reducing construction quality risks. This design increases the flexibility of the equipment and improves its adaptability to complex geological conditions.

[0027] 5. It can reduce the cost of use for customers. The relevant adjustment structure can compensate for the wear and tear during use. The service life of the product can be increased by more than 3 years, and the construction reliability is higher. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The present invention will be described in further detail below with reference to the embodiments in the accompanying drawings.

[0039] like Figures 1 to 9 As shown, a specific embodiment of the core drilling rig power head fixing mechanism of the present invention.

[0040] like Figure 1 、 Figure 2 and Figure 5 As shown, the core drilling rig power head fixing mechanism of this embodiment includes a power head 1, an upper and lower movable bracket 2, a side sliding bracket 4 and a side sliding drive mechanism 6. The upper and lower movable bracket 2 is provided with a cavity 2a extending along the side sliding direction, and the cavity 2a accommodates the side sliding drive mechanism 6. The side sliding bracket 4 is provided on the front side of the cavity 2a, and the power head 1 is provided on the side sliding bracket 4; the side sliding drive mechanism 6 is respectively connected to the upper and lower movable bracket 2 and the side sliding bracket 4 and drives the side sliding bracket 4 to slide back and forth relative to the upper and lower movable bracket 2.

[0041] The core drilling rig fixing mechanism is provided with a cavity to accommodate the side sliding drive mechanism, which can provide a better side sliding force effect for the side sliding bracket, not only saving space but also improving the stability of the side sliding.

[0042] like Figure 1 and Figure 5 As shown, the side sliding drive mechanism 6 is a side sliding cylinder 6a, the fixed end of the side sliding cylinder 6a is connected to the upper and lower movable brackets 2, and the movable end is connected to the side sliding bracket 4. The side sliding bracket is driven by the side sliding cylinder to achieve precise control of the lateral sliding of the power head and convenient operation.

[0043] like Figure 5 and Figures 7 to 9 As shown, the vertically movable bracket 2 includes a bracket body 2b, which is formed by bending a flat plate to form two raised portions 2c, with a cavity 2a formed between the two raised portions 2c. The bracket body of the vertically movable bracket adopts a flat plate structure with multiple bendings, which improves rigidity and strength. At the same time, the cavity formed in the middle facilitates the arrangement of the side-sliding drive mechanism and improves the side-sliding force effect in the middle.

[0044] like Figure 1 、 Figure 2 and Figure 5 As shown, the core drilling rig fixing mechanism also includes two side sliding guide rails 5, which are respectively provided on both sides of the cavity 2a and connected to the vertical movable bracket 2. Both sides of the side sliding bracket 4 are respectively located in the side sliding guide rails 5. The side sliding guide rails on both sides of the cavity of the vertical movable bracket facilitate the back and forth lateral movement of the side sliding bracket, ensuring smooth and stable side sliding and reliability during the operation of the power head.

[0045] like Figure 1 and Figure 2As shown, the core drilling rig fixing mechanism also includes an up-down drive mechanism 3, which is connected to the up-down movable bracket 2 and drives it to move up and down. The up-down drive mechanism drives the up-down movable bracket to move up and down, and ultimately drives the power head to move up and down through the side sliding bracket to meet the working requirements of different working conditions.

[0046] like Figure 1 and Figure 2 As shown, the up and down driving mechanism 3 is an up and down moving oil cylinder 3a, and the piston rod end of the up and down moving oil cylinder 3a is hinged and positioned; Figure 3 As shown, the vertical movable bracket 2 is connected to the cylinder barrel of the vertical movable cylinder 3a. During normal operation, the power head 1 is located directly in front of the vertical movable cylinder 3a. After the drilling operation is completed, when core retrieval is required, the side sliding cylinder 6a pushes the side sliding bracket 4 and the power head 1 away from the drilling position and moves to the side, making it easier to retrieve the core. The vertical movable bracket is driven by the vertical movable cylinder to achieve the vertical sliding of the power head, ensuring smooth and reliable up and down movement.

The nut ends of the adjustment screws 10 are threadedly connected to the locking nuts 11. If the vertical movable bracket 2 becomes loose or wears after a period of operation, the relative position between the V-shaped slider 9 and the vertical movable bracket 2 can be adjusted by adjusting the screws 10, and then locked in position by the locking nuts 11 to ensure that the V-shaped slider slides smoothly and stably on the V-shaped guide rail.

[0049] The utility model also discloses a core drilling rig, comprising the core drilling rig power head fixing mechanism.

[0050] The core drilling rig can realize the power head structure of up and down sliding and sideways sliding during geological exploration. The specific implementation steps are as follows:

The power head is fixed to the side sliding bracket, and the vertical movable bracket is equipped with a V-shaped slider. The V-shaped slider fits on the V-shaped guide rail on the frame and slides up and down.

[0052] Step 2: Prepare the side sliding cylinder. The side sliding cylinder is arranged in the middle cavity of the upper and lower movable brackets. By controlling the extension and contraction of the side sliding cylinder, the side sliding of the side sliding bracket can be achieved.

[0053] Step 3: Adjust the up and down movable bracket. When the V-shaped slider and the V-shaped guide rail on the frame are worn, the relative position of the V-shaped slider and the up and down movable bracket can be adjusted by adjusting the bolts to ensure smooth operation of the up and down movable bracket.

[0054] Step 4: Slide the power head up and down. By controlling the V-shaped slider of the up and down movable bracket, the up and down movable bracket is tightly fitted with the V-shaped guide rail on the frame to realize the up and down sliding of the power head.

[0055] The vertically movable bracket in this embodiment utilizes a multi-bend structure, enhancing rigidity and strength. A central cavity facilitates the placement of the sliding cylinder, improving side-sliding stability. The vertically movable bracket's simple structure and easy manufacturing process reduce weight and control costs. Driven by the sliding cylinder, the power head achieves precise control and convenient operation.

This structural design not only improves the stability and service life of the equipment, but also significantly reduces labor intensity and improves work efficiency. Therefore, this technical solution has broad application prospects in the field of geological exploration equipment.

[0058] In the field of drilling rig design and manufacturing, this technical solution utilizes a multi-bend structure for vertically movable supports. This structure improves rigidity and strength while facilitating the placement of the side-sliding cylinders.
