And this clamping method based on the air bag can provide uniform and comprehensive clamping force, compared with the traditional mechanical clamping method, which avoids the risk of local stress concentration causing damage to the spherical support block, effectively protecting the integrity and service life of the spherical support block. At the same time, the utility model can also flexibly adjust the clamping force of the clamping air bag by controlling the inflation amount of the air pump, so as to adapt to spherical support blocks of different weights and materials and various complex working environments, greatly improving the applicability of the device. In addition, the support block clamping mechanism also has the characteristics of compact structure, which cleverly uses the space in the annular groove to place the clamping air bag, without occupying too much device space, while ensuring good clamping function, maintaining the simplicity and compactness of the overall structure of the device, and providing strong support for the anchor rod installation auxiliary device for conveniently adjusting the angle to play a stable and efficient performance in practical application.

[0029] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0030] like Figures 1 to 4As shown, this utility model provides an anchor bolt installation auxiliary device that facilitates angle adjustment. It includes a base 1, with a fixing seat 2 at the lower end of the base 1. A mounting hole 21 is passed through the middle of the fixing seat 2. During the anchor bolt installation operation, anchor bolts can be passed through the mounting hole 21 and screwed into the ground or other installation surfaces, thereby firmly fixing the base 1 and the entire device in the working position. This effectively avoids displacement or shaking of the device due to vibration, external impact, or other factors during construction, thus greatly ensuring the stability of the device during anchor bolt installation, ensuring the accuracy and consistency of the anchor bolt installation angle, and significantly improving the installation quality of the anchor bolt.

[0031] The upper surface of the base 1 is provided with a hemispherical support groove 24, and a spherical support block 20 is provided inside the support groove 24. The spherical support block 20 and the support groove 24 form a spherical kinematic pair, meaning the spherical support block 20 can rotate in multiple directions within the support groove 24. To ensure smooth rotation of the spherical support block 20, at least one ring of ball bearing grooves 23 is provided on the groove wall of the support groove 24. Supporting balls 22 are rotatably installed in each ball bearing groove 23, and the supporting balls 22 are in contact with the surface of the spherical support block 20, thereby supporting the spherical support block 20. In this way, the presence of the supporting balls 22 greatly reduces the friction between the spherical support block 20 and the support groove 24, making the rotation and sliding of the spherical support block 20 within the support groove 24 smoother and more flexible, and making it easier and less strenuous for operators to adjust the angle and direction of the spherical support block 20. Meanwhile, this utility model can evenly distribute the supporting balls 22 on the groove wall of the supporting groove 24, thereby providing all-round support for the spherical support block 20, dispersing the pressure borne by the spherical support block 20, reducing local wear, extending the service life of the spherical support block 20 and the supporting groove 24, and further improving the stability and reliability of the device.

[0032] To ensure that the spherical support block 20 maintains its corresponding state after rotating to the appropriate angle, this invention also provides a support block clamping mechanism on the groove wall of the support groove 24, enabling the clamping mechanism to clamp the spherical support block 20. When the operator adjusts the spherical support block 20 to the appropriate position using the spherical motion pair, aligning the anchor rod 7 on the mounting frame 5 with the ideal installation angle, the clamping mechanism can be activated to firmly clamp the spherical support block 20. This effectively prevents accidental rotation or displacement of the spherical support block 20 during anchor rod 7 installation due to external forces or operational vibrations, ensuring that the angle of the anchor rod 7 remains accurate throughout the installation process. This significantly improves the stability and reliability of the anchor rod 7 installation, thereby enhancing the installation quality. Furthermore, the clamping mechanism's ability to release when angle adjustment is needed and clamp again after adjustment provides a convenient operating experience and improves work efficiency.

[0033] Specifically, such as Figure 4 As shown, the support block clamping mechanism includes an annular groove 27 formed on the groove wall of the support groove 24. The annular groove 27 can be set horizontally or perpendicular to the groove wall of the support groove 24, and a clamping airbag 25 is placed inside the annular groove 27. The clamping airbag 25 is made of rubber with high friction, and an air supply pipe 26 is connected to the side of the clamping airbag 25 facing the bottom of the annular groove 27. The air supply pipe 26 is connected to an air pump 3. At this time, when it is necessary to clamp and fix the spherical support block 20, the air pump 3 can be started first. The air pump 3 inflates the clamping airbag 25 through the air supply pipe 26. As the gas is inflated, the clamping airbag 25 will gradually expand, expanding outward from the annular groove 27, and finally tightly adhering to and squeezing the surface of the spherical support block 20, thereby achieving a stable clamping of the spherical support block 20. Furthermore, this airbag-based clamping method can provide uniform and comprehensive clamping force. Compared with traditional mechanical clamping methods, it avoids the risk of damage to the spherical support block 20 caused by local stress concentration, effectively ensuring the integrity and service life of the spherical support block 20.

[0034] In addition to the above-mentioned structure, this utility model can also employ other conventional clamping structures, such as a structure in which a deep groove is formed horizontally along the wall of the support groove 24, and a telescopic rod is installed in each deep groove. In this case, when it is necessary to clamp and fix the spherical support block 20, the telescopic rods in each deep groove can be directly controlled to unfold, and the ends of each telescopic rod abut against the surface of the spherical support block 20; at this time, the spherical support block 20 can be securely clamped through the abutment of each telescopic rod against the spherical support block.

[0035] To improve the accuracy of angle adjustment and reduce installation errors, this invention features a horizontal scale line 4 around the outer side of the support groove 24 and a vertical scale line 19 on the surface of the spherical support block 20. These horizontal and vertical scale lines provide operators with intuitive and precise angle references. When adjusting the angle of the spherical support block 20, operators can quickly determine the current horizontal angle of the spherical support block 20 based on the value of the horizontal scale line 4 aligned with the vertical scale line 19. Furthermore, based on the value of the vertical scale line 19 aligned with the horizontal scale line 4, operators can clearly understand the current rotation range of the spherical support block 20 in the vertical direction. This significantly improves the accuracy of angle adjustment, effectively reduces installation errors caused by angle deviations, and enhances the quality of anchor bolt 7 installation.

[0036] In addition, such as Figure 1 , Figure 2 As shown, this utility model also provides a fixing groove 9 at the end of the spherical support block 20, and a mounting bracket 5 is fixedly installed in the fixing groove 9 by bolts or other fasteners. An anchor rod clamping and moving mechanism is provided on the upper surface of the mounting bracket 5. Specifically, as shown... Figure 2 , Figure 3 As shown, the anchor bolt clamping and moving mechanism includes a first mounting plate 17 and a second mounting plate 6 fixedly mounted on the mounting frame 5. The upper end of the second mounting plate 6 has an anchor bolt sliding hole 28. A ball screw 8 is rotatably mounted between the first mounting plate 17 and the second mounting plate 6. The end of the ball screw 8 passes through the first mounting plate 17 and is connected to a drive motor 18. A movable slider 15 is threadedly connected to the middle of the ball screw 8. An anchor bolt abutment frame 16 is provided on one end of the movable slider 15 near the first mounting plate 17, and the anchor bolt abutment frame 16 is positioned opposite to the anchor bolt sliding hole 28. A clamping groove 11 is formed on the upper surface of the movable slider 15. A bidirectional screw 10 is rotatably mounted in the clamping groove 11. The end of the bidirectional screw 10 passes through the movable slider 15 and is connected to a rotating handle 14. Each of the two threaded sections of the bidirectional screw 10 is threadedly connected to a clamping slider 12. An arc-shaped clamping plate 13 is provided at the upper end of the clamping slider 12.

[0037] Based on this, when installing the anchor rod 7 using this device, the bidirectional screw 10 can be rotated in the reverse direction first to control the two clamping sliders 12 to move away from each other. Then, one end of the anchor rod 7 passes through the anchor rod sliding hole 28, and the other end passes through the two arc-shaped clamping plates 13 and abuts against the anchor rod abutment frame 16. Then, the bidirectional screw 10 is rotated in the forward direction to control the two clamping sliders 12 to move closer to each other, so as to fix the anchor rod 7 on this device. Next, the angle of the mounting frame 5 and the anchor rod 7 is adjusted by rotating the spherical support block 20. Finally, after the angle of the mounting frame 5 is adjusted, the support block clamping mechanism can be controlled to clamp the spherical support block 20, and then the drive motor 18 can be powered on. At this time, the drive motor 18 outputs rotational power and transmits the power to the… At the ball screw 8 connected to the sliding block 15, since the ball screw 8 and the sliding block 15 are connected by a thread, when the ball screw 8 is driven to rotate by the drive motor 18, according to the thread transmission principle and the matching structure between the anchor rod 7 and the anchor rod sliding hole 28, the sliding block 15 will move linearly along the axial direction of the ball screw 8 under the drive of the ball screw 8. At the same time, during the movement of the sliding block 15, the anchor rod abutment frame 16 set at one end near the mounting plate 17 plays a key role. The anchor rod abutment frame 16 will contact the anchor rod 7 placed in the anchor rod sliding hole 28 and push the anchor rod 7, so that the anchor rod 7 moves linearly along the anchor rod sliding hole 28, thereby realizing the installation of the anchor rod 7 and ensuring that the anchor rod 7 can accurately reach the preset installation position.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
