Description

Technical Field

[0001] This utility model relates to an adjustable anchor cable positioning device, belonging to the field of anchor cable positioning technology. Background Technology

[0002] Anchor cables, as a very common support method, are widely used in areas with complex geological conditions, such as slopes, tunnels, and mining. The wainscoting is a lateral force-transferring component in foundation pit or retaining structure support. It is usually made of reinforced concrete or steel and is installed at the waist or middle height of the support structure (such as pile walls, diaphragm walls, etc.). Its main function is to evenly transfer the concentrated force of anchor bolts, internal supports, or diagonal braces horizontally to the entire retaining wall (pile), thereby improving the overall stability of the retaining structure. In actual construction, especially under complex geological conditions or conditions severely constrained by existing structures, accurate construction layout is difficult, and the designed hole positions are often difficult to accurately construct according to the drawings. This initial positioning difficulty often leads to excessive deviation in the final installation position of the anchor cables, causing them to not accurately match the perforation position with the wainscoting (or capping beam, waler) or to be unable to be inserted. Sometimes, the pre-reserved holes in the wainscoting even need to be repeatedly cut and enlarged on-site. This positioning deviation seriously weakens the support effectiveness of the anchor cables and the overall structural stability. However, there are shortcomings in how to achieve accurate anchor cable positioning and how to adjust the anchor cable in the face of the above positioning challenges. Utility Model Content

[0003] Based on the above, this utility model provides an adjustable anchor cable positioning device to ensure accurate anchor cable positioning and enable the anchor cable to achieve the maximum support effect.

[0004] The technical solution of this utility model is: an adjustable anchor cable positioning device, comprising:

[0005] A horizontal positioning frame is provided with a front positioning hole and a rear positioning hole at the front and back, respectively, and support plates are provided on the left and right sides of the horizontal positioning frame.

[0006] The drilling positioning frame has its front two sides hinged to the support plate, and its rear side is installed on the rear side of the horizontal positioning frame through an adjusting bracket. The front and rear sides of the drilling positioning frame are respectively provided with corresponding front positioning reserved holes and rear positioning reserved holes.

[0007] In one example, a positioning ring is provided on the outer side of the bottom front end of the horizontal positioning frame as the front point positioning hole, and the front point positioning hole and the rear point positioning hole are arranged vertically.

[0008] In one example, the front ends of the drilling positioning frame are mounted to the support plate by first rotatable bolts.

[0009] In one example, the adjusting bracket includes a second rotatable bolt, an angle adjusting plate, and an adjustable bolt. The lower end of the angle adjusting plate is mounted to both sides of the rear end of the horizontal positioning frame via the second rotatable bolt. The upper part of the angle adjusting plate has a slot, and the adjustable bolt is mounted to both sides of the drilling positioning frame through the slot.

[0010] The beneficial effects of this utility model are as follows: First, the horizontal position is achieved by using the front and rear positioning holes of the horizontal positioning frame. Then, after adjusting the drilling positioning frame to the predetermined tilt angle, the anchor cable drilling point is accurately obtained by using the principle of two points forming a line through the front and rear positioning reserved holes. Compared with the prior art, this utility model can ensure the accurate positioning of the anchor cable and enable the anchor cable to achieve the maximum support effect. Attached Figure Description

[0017] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0018] Please see Figures 1 to 3 This embodiment provides an adjustable anchor cable positioning device, which includes a horizontal positioning frame 1 and a drilling positioning frame 2.

[0019] The horizontal positioning frame 1 has a square frame structure, with a front positioning hole 11 and a rear positioning hole 12 at the front and rear respectively. A positioning ring 13 is fixed on the outer side of the bottom front end of the horizontal positioning frame 1 as the front positioning hole 11, and the rear positioning hole 12 is opened on the rear end frame of the horizontal positioning frame 1. Both the front positioning hole 11 and the rear positioning hole 12 are vertically set to facilitate observation of the line laying position.

[0020] Support plates 14 are installed on both the left and right sides of the horizontal positioning frame 1. The front two sides of the drilling positioning frame 2 are hinged to the support plates 14. Specifically, the front two sides of the drilling positioning frame 2 are installed on the support plates 14 by the first rotatable bolts 15. The drilling positioning frame 2 can rotate relative to the support plates 14. Its rear side can be adjusted and installed on the rear side of the horizontal positioning frame 1 by the adjusting bracket 23. The front and rear sides of the drilling positioning frame 2 are respectively provided with corresponding front positioning reserved holes 21 and rear positioning reserved holes 22.

[0021] For ease of operation, the adjustment bracket 23 includes a second rotatable bolt 231, an angle adjustment plate 232, and an adjustable bolt 233. The lower end of the angle adjustment plate 232 is installed on both sides of the rear end of the horizontal positioning frame 1 through the second rotatable bolt 231. A strip-shaped opening 234 is provided on the upper part of the angle adjustment plate 232, and the adjustable bolt 233 is installed on both sides of the drilling positioning frame 2 through the strip-shaped opening 234.

[0022] The construction method for the above-mentioned adjustable anchor cable positioning device is as follows:

[0023] First, lay out the positioning lines on the construction surface and fix the horizontal positioning frame 1 to the construction surface. Observe and determine the horizontal position of the anchor cable through its front positioning hole 11 (positioning ring 13) and rear positioning hole 12, and appropriately raise the height of the horizontal positioning frame 1 according to the requirements. Second, rotate the angle adjustment plate 232 to a suitable height, and then adjust it to a suitable position within the strip opening 234 using the second adjusting bolt, and fix it by rotating the adjustable bolt 233. Finally, the anchor cable drilling point can be accurately obtained by using the principle of two points forming a line through the front positioning reserved hole 21 and the rear positioning reserved hole 22.

[0024] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent.
