[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Please also refer to Figures 1 to 3 The anchor bolt fixing and positioning structure provided by the present invention will now be described. The anchor bolt fixing and positioning structure comprises a mounting plate 1, an anchor bolt 2, a positioning hook 3, and a fixing nut 4. The mounting plate 1 is fixedly mounted on the equipment to be mounted; the mounting plate 1 is provided with through holes for mounting the anchor bolts 2; there are multiple positioning hooks 3, which are evenly arranged on the outer ring of the anchor bolt 2 along the circumference of the anchor bolt 2. The positioning hook 3 comprises a positioning rod 32 for being inserted between the anchor bolt 2 and the inner wall of the through hole on the mounting plate 1; the fixing nut 4 is threadedly connected to the anchor bolt 2 and is used to fix the positioning hook 3 to the mounting plate 1.

[0024] The anchor bolt fixing and positioning structure provided in this embodiment, compared to the prior art, features a mounting plate 1 fixedly mounted on the bottom of the device to be installed. The mounting plate 1 includes a through-hole for receiving an anchor bolt 2, the inner diameter of which is larger than the outer diameter of the anchor bolt 2. To install the anchor bolt 2, the device is first mounted on the ground. The anchor bolt 2 is then placed inside the through-hole. The positioning rods 32 on the multiple positioning hooks 3 are positioned within the gap between the anchor bolt 2 and the through-hole, positioning the anchor bolt 2 in the middle of the through-hole. This allows the anchor bolt 2 to be positioned within the through-hole on the mounting plate 1. The positioning hooks 3 are then secured to the mounting plate 1 using fixing nuts 4. Finally, the anchor bolt 2 is secured to the ground by grouting. After the anchor bolt 2 is secured, the fixing nuts 4 and positioning hooks 3 are removed. During subsequent device docking, the clearance between the circumference of the anchor bolt 2 and the inner wall of the through-hole allows for fine-tuning of the device's installation position, facilitating subsequent docking and installation.

[0025] In some embodiments, the positioning hook 3 can be used as follows Figure 2 、 Figure 3 See also Figure 2 、 Figure 3 The positioning hook 3 also includes a fixing portion for overlapping the mounting plate 1, which is fixedly connected to the positioning rod 32. When the positioning rod 32 is located within the through-hole in the mounting plate 1, the fixing portion overlaps the mounting plate 1. When the fixing nut 4 is installed on the anchor bolt 2, the fixing nut 4 can press the fixing portion against the mounting plate 1, thereby fixing the positioning hook 3 between the fixing nut 4 and the mounting plate 1, ensuring the stability of the position of the positioning rod 32 between the through-hole and the anchor bolt 2.

[0026] In some embodiments, the fixing portion may be Figure 2 、 Figure 3 See also Figure 2 、 Figure 3 The fixing portion includes two overlapping rods 31 arranged at an angle, and a positioning rod 32 is bent on each of the two overlapping rods 31. The fixing portion includes two overlapping rods 31, one end of the two overlapping rods 31 is fixedly connected, and a positioning rod 32 is bent on the other end of the two overlapping rods 31. The positioning rod 32 and the overlapping rod 31 are arranged perpendicular to each other. When the positioning rod 32 is located inside the through hole, the overlapping rod 31 is just overlapped on the top surface of the mounting plate 1. The positioning hook 3 as a whole can be formed by bending steel wire in one piece, which has a simple structure and is convenient for processing the positioning hook 3.

[0027] In some embodiments, the positioning hook 3 can be used as follows Figure 2 、 Figure 3 See also Figure 2 、 Figure 3 The lap rod 31 and the positioning rod 32 are arranged perpendicular to each other. When installing the positioning hook 3, the lap rod 31 overlaps the top surface of the mounting plate 1, and the positioning rod 32 is located inside the through-hole. The positioning rod 32 and the axis of the through-hole are arranged perpendicular to each other. This prevents the positioning rod 32 from driving the anchor bolt 2 inside the through-hole, ensuring the anchor bolt 2 is positioned within the through-hole. This avoids the problem of no gap or small gap on one side. It also facilitates the use of the fixing nut 4 to secure the lap rod 31 to the top surface of the mounting plate 1.

[0028] In some embodiments, the above-mentioned connecting rod 31 can be used as follows Figure 2 、 Figure 3 See also Figure 2 、 Figure 3 , the two lap rods 31 are an integrally bent structure. The two lap rods 31 are made of elastic material. And the two lap rods 31 are integrally bent. The distance between the two lap rods 31 can be adjusted according to the size of the on-site through-hole. When the through-hole size is too small, the distance between the two lap rods 31 can be made smaller by squeezing the two lap rods 31. This makes it convenient to place the positioning rods 32 on the two lap rods 31 inside the through-hole. And the positioning hook 3 is integrally bent, which facilitates the processing of the positioning hook 3 and saves the processing cost of the positioning hook 3.

[0029] In some embodiments, the mounting plate 1 may be used as follows Figure 1 The structure shown. Figure 1A support block 5 is also installed below the mounting plate 1. This support block 5 is used to secure it to the ground and is provided with a fixing slot for mounting the anchor bolt 2. When installing the anchor bolt 2, the support block 5 can be pre-buried and fixed inside the foundation pit. The mounting plate 1 on the equipment is then overlapped with the support block 5. Finally, the anchor bolt 2 is passed through the mounting plate 1 and installed inside the fixing slot. The anchor bolt 2 is secured to the inside of the fixing slot by grouting the inside of the fixing slot. The provision of the support block 5 can provide a certain degree of support for the equipment and ensure the stability of the equipment installation.

[0030] In some embodiments, the support block 5 may be formed as follows: Figure 1 The structure shown. Figure 1 The length of the fixing groove on the support block 5 is arranged in the vertical direction, and the width of the fixing groove gradually decreases from top to bottom. The support block 5 is pre-buried and fixed in the ground along the vertical direction. The width of the fixing groove gradually decreases from top to bottom. Therefore, during grouting, the slurry used to fix the anchor bolt 2 can be effectively transported into the fixing groove, ensuring the stability of the anchor bolt 2.

[0031] In some embodiments, the positioning hook 3 can be used as follows Figure 2 The structure shown. Figure 2 , the two positioning rods 32 on the positioning hook 3 are arranged in parallel at intervals, and the two overlapping rods 31 are arranged at an angle along the arrangement direction of the two positioning rods 32. When the positioning hook 3 is installed inside the through-hole, the two positioning rods 32 are spaced apart and abut against the inner wall of the through-hole on the mounting plate 1, and the two positioning rods 32 are spaced apart along the circumference of the through-hole. Preferably, in this embodiment, two or three positioning hooks 3 are installed at each through-hole, and the positioning rods on the positioning hook 3 are evenly spaced on the inner wall of the through-hole. Thereby, a plurality of positioning rods 32 are arranged around the outside of the anchor bolt 2 to ensure that the gap between the outer wall of the anchor bolt 2 and the inner wall of the through-hole on the mounting plate 1 is uniform. After the anchor bolt 2 is fixed by grouting, the positioning hook 3 can be removed by removing the fixing nut 4. It does not affect the position of the later fine-tuning equipment. The structure is simple and easy to operate.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
