[0020] The specific embodiments of this utility model are further described below:

[0021] This embodiment provides an anchor positioning device for deep foundation pit support.

[0022] The anchor positioning device is based on a main support frame 1. The main support frame 1 is a triangular stable structure formed by welding three channel steels end to end. One of the channel steels serves as the bottom channel steel, and the triangular corner opposite the bottom channel steel serves as the top corner. A round steel bar is fixed at the top corner as a crossbar 11, and the two triangular corners adjacent to the bottom channel steel serve as the bottom corners.

[0023] The anchor positioning device of this embodiment also includes a steel pipe as a guide steel pipe 2, with one end of the guide steel pipe 2 serving as the rear end and the other end of the guide steel pipe 2 serving as the front end.

[0024] The rear end of the guide steel pipe 2 is connected to the main support frame 1 by three telescopic cables 3.

[0025] Specifically

[0026] The rear end of the guide steel pipe 2 is connected to the end of the crossbar 11 near the main support frame 1 via a telescopic cable 3. The rear end of the guide steel pipe 2 is connected to the two bottom corners of the main support frame 1 via two telescopic cables 3 respectively. The connection points of the three telescopic cables 3 to the guide steel pipe 2 are discrete and evenly distributed at the rear end of the guide steel pipe 2. The front end of the guide steel pipe 2 is connected to the end of the crossbar 11 away from the main support frame 1 via a telescopic cable 3.

[0027] The middle part of the guide steel pipe 2 is also connected to the bottom edge channel steel of the main support frame 1 through a support rod 5.

[0028] It should be noted that both ends of the telescopic cable 3 and the support rod 5 are connected to other components by means of hinged pivot pins. In this way, the guide steel pipe 2 can adjust its posture within a two-dimensional range, such as tilting, standing upright, lying horizontally, etc.

[0029] It should be noted that the telescopic cable 3 used in this embodiment is a component of the prior art, which has a turnbuckle in its middle, thereby giving it the function of telescopic extension.

[0030] See Figure 1 and Figure 2 A coarse angle adjustment mechanism 6 is also provided at the hinge joint between the support rod 5 and the bottom channel steel of the main support frame 1. The function of the coarse angle adjustment mechanism 6 is to roughly adjust the angle of the guide steel pipe 2 so that it reaches the design angle.

[0031] Specifically

[0032] The coarse angle adjustment mechanism 6 includes a first angle adjustment plate 61 and a first pin 62. The first angle adjustment plate 61 is fixedly connected to the main support frame 1. The first angle adjustment plate 61 is provided with an elongated arc-shaped hole. The first pin 62 is fixedly mounted on the support rod 5 and passes through the elongated arc-shaped hole of the first angle adjustment plate 61. The first pin 62 and the elongated arc-shaped hole of the first angle adjustment plate 61 cooperate with each other to roughly adjust the angle of the anchor rod.

[0033] See Figure 1 and Figure 3A precision angle adjustment mechanism 7 is also provided at the hinge joint between the support rod 5 and the guide steel pipe 2. The function of the precision angle adjustment mechanism 7 is to precisely adjust the angle so that it reaches the design angle.

[0034] Specifically

[0035] The precision angle adjustment mechanism 7 includes a second angle adjustment disk 71 and a moving probe 72. The second angle adjustment disk 71 is fixedly connected to the support rod 5. The second angle adjustment disk 71 is provided with an elongated arc-shaped hole. The moving probe 72 is provided with a second pin 721 and a probe head 722, which are perpendicular to each other. The second pin 721 is embedded in the elongated arc-shaped hole of the second angle adjustment disk 71. A locking bolt is provided at the end of the second pin 721.

[0036] When the locking bolt is in the unlocked state, the movable probe 72 can move along the elongated arc-shaped hole of the second angle adjustment plate 71. When the locking bolt is adjusted to the locked state, the movable probe 72 can be fixed on the second angle adjustment plate 71. The probe head 722 can face the guide steel pipe 2 above and abut against the surface of the guide steel pipe 2 for precise adjustment of the angle of the guide steel pipe 2.

[0037] It should be noted that both the first angle adjustment plate 61 and the second angle adjustment plate 71 are provided with angle scales to facilitate understanding the angle of the guide steel pipe 2.

[0038] The following describes the usage and working principle of the anchor bolt positioning device in this embodiment:

[0039] 1) Fix the main support frame 1 to the working surface where the anchor bolts need to be installed;

[0040] 2) Adjust the telescopic cable 3 so that the guide steel pipe 2 is approximately located at the point where the anchor bolt needs to be installed;

[0041] 3) Adjust the coarse angle adjustment mechanism 6 to roughly achieve the design value for the anchor bolt angle;

[0042] 4) Adjust the precision angle adjustment mechanism 7 to make the anchor bolt angle more accurately close to the design value;

[0043] 5) After the design value is accurately reached, the telescopic cable 3 is fixed and the anchor drilling rig inserts the drill bit into the guide steel pipe 2 to start construction.

[0044] The main advantages of the anchor bolt positioning device in this embodiment are:

[0045] 1) The rear end of the guide steel pipe 2 is connected to the main support frame 1 through 3 telescopic cables 3, and then a support rod 5 is set in the middle of the guide steel pipe 2. In this way, the angle of the guide steel pipe 2 can be freely adjusted, which makes it easier to accurately control the installation angle of the anchor rod.

[0046] In addition, the anchor bolt positioning device of this embodiment has other advantages, as follows:

[0047] 2) Through the cooperation of the positioning device and the control system, the precise positioning and installation of the anchor bolts are achieved, improving the angle and position accuracy of the anchor bolts, thereby enhancing the stability of the support structure;

[0048] 3) The pressure sensor and control system in the grouting device can monitor and control the grouting pressure and grouting volume in real time to ensure grouting quality and improve the anchoring force of the anchor bolt;

[0049] The entire construction process is highly automated, which reduces the labor intensity of construction workers and improves construction efficiency.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
