If the driving angle deviates, the steel frame may sink or converge, resulting in deformation of the initial support, which not only affects the quality of the initial support, but also poses certain safety hazards.

[0006] In this solution, the base includes a first side plate, a second side plate and a third side plate, so that the overall shape of the base is U-shaped, so that the base can be clamped from one side of the flange plate of the steel arch frame. Then, by arranging a clamping plate unit on the first side plate, under the action of the position adjustment component, the clamping plate can be driven to move toward the second side plate, so that the clamping plate and the second side plate are respectively clamped on both sides of the flange plate of the steel arch frame, so that the locking foot anchor rod angle controller is fixed to the flange plate of the steel arch frame, and the locking foot anchor rod angle controller is fixed.

[0039] In this solution, the base 10 includes a first side plate 11, a second side plate 12 and a third side plate 13, so that the overall shape of the base 10 is U-shaped, so that the base 10 can be clamped from one side of the flange plate of the steel arch frame 200. Then, by arranging a clamping plate unit 30 on the first side plate 11, under the action of the position adjustment component 32, the clamping plate 31 can be driven to move toward the second side plate 12, so that the clamping plate 31 and the second side plate 12 are respectively clamped on both sides of the flange plate of the steel arch frame 200, so that the locking foot anchor rod angle controller 100 is fixed to the flange plate of the steel arch frame 200, and the locking foot anchor rod angle controller 100 is fixed. When the locking foot anchor rod is installed, the locking foot anchor rod is passed through the guide tube assembly 21, and then the angle of the guide tube assembly 21 is adjusted to the right position through the angle adjustment assembly 22. The guide tube assembly 21 provides guiding and supporting functions for the locking foot screw. The worker allows the locking foot screw to be installed at a fixed angle, and a locking foot anchor rod hole with an angle that meets the requirements of the specification can be installed.
[0040] The first side plate 11, the second side plate 12 and the third side plate 13 in the base 10 can be made of steel plates, and the first side plate 11, the second side plate 12 and the third side plate 13 are welded and fixed. The base 10 is formed with three openings, namely, a top opening, a bottom opening and a side opening, and the base 10 can be inserted into the flange plate of the steel arch 200 through the side opening.
[0041] In some embodiments, the position adjustment component 32 includes an installation box 320, a first adjustment screw 321 and a nut seat 322. The installation box 320 is arranged on a side of the first side plate 11 away from the second side plate 12, and the installation box 320 has an installation cavity; along the distribution direction of the first side plate 11 and the second side plate 12, the first adjustment screw 321 is rotatably installed in the installation cavity, the nut seat 322 is located in the installation cavity and threadedly cooperates with the first adjustment screw 321, and a connecting plate assembly 33 is connected between the nut seat 322 and the clamping plate 31, and the installation box 320 is correspondingly provided with a first clearance hole for the connecting plate assembly 33 to extend, and the first side plate 11 is correspondingly provided with a second clearance hole for making way for the connecting plate assembly 33; the first adjustment screw 321 is used to drive the nut seat 322 to move along the extension direction of the first adjustment screw 321 when rotating along its own axial direction, so that the clamping plate 31 can be close to or away from the second side plate 12. When the bolt 321 is in the unlocking state, the first screw 321 is locked and the unlocking state is achieved, so the first screw 321 can be unlocked and the second screw 321 can be unlocked to unlock the second locking plate 31.
[0042] The installation box 320 is a box structure, and the material of the installation box 320 can be a steel plate material. The installation box 320 is welded and fixed to the outer side of the first side plate 11. In addition, the connecting plate assembly 33 can include a plurality of connecting plates 330, and the plurality of connecting plates 330 are inserted through the clearance holes of the installation box 320 and the second side plate 12 and then welded and fixed to different positions of the clamping plate 31. The opening size of the first clearance hole is adapted to the shape of the connecting plate assembly 33, so that the first clearance hole can limit the connection plate 330, that is, under the cooperation of the plurality of connecting plates 330 and the first clearance hole, the nut seat 322 can be prevented from rotating, so that the nut seat 322 can only move along the extension direction of the first adjusting screw 321.
[0043] In some embodiments, the connecting plate assembly 33 includes two connecting plates 330, and the two ends of the two connecting plates 330 in the length direction are respectively connected to the nut seat 322 and the clamping plate 31. By connecting the two connecting plates 330 to the nut seat 322 and the clamping plate 31 respectively, on the one hand, the two connecting plates 330 can play the role of connecting the clamping plate 31 and the nut seat 322 as a whole, and the connection strength is high, and the clamping plate 31 is not easy to fall off. On the other hand, the two connecting plates 330 cooperate with the first clearance holes on the installation box 320 to play the function of preventing the nut seat 322 from rotating.
[0044] In some embodiments, the clamping plate 31 has a first surface 310 facing the second side plate 12, and the surface area of the first surface 310 is not less than the area of the second clearance hole. Since the surface area of the first surface 310 is not less than the area of the second clearance hole, the contact area between the clamping plate 31 and the flange plate of the steel arch frame 200 is relatively larger, and the clamping stability between the clamping plate 31 and the flange plate of the steel arch frame 200 can be further enhanced.
[0045] It can be understood that when the surface area of the first surface 310 is equal to the area of the second clearance hole, the clamp 31 can still be retracted into the second clearance hole of the first side plate 11, and when the surface area of the first surface 310 is greater than the area of the second clearance hole, the clamp 31 cannot be retracted into the second clearance hole of the first side plate 11, that is, the maximum stroke of the clamp 31 close to the side of the installation box 320 is, and the clamp 31 is limited and held against the side wall of the first side plate 11.
[0046] In some embodiments, the first surface 310 is provided with an anti-slip portion. By providing the anti-slip portion on the first surface 310 of the clamping plate 31, the anti-slip portion can increase the friction force between the clamping plate 31 and the flange plate of the steel arch frame 200, thereby further improving the clamping stability of the clamping plate 31 and the second side plate 12 on the flange plate of the steel arch frame 200.
[0047] Among them, the anti-slip part can be a variety of anti-slip structures. For example, the anti-slip part can be a plurality of protrusions arranged on the first surface 310, or a plurality of anti-slip lines distributed on the first surface 310, that is, a plurality of linear anti-slip protrusions or anti-slip grooves.
[0048] In some embodiments, an L-shaped rotating handle 323 is provided at one end of the first adjusting screw 321 away from the clamping plate 31. By providing a rotating handle 323 on the first adjusting screw 321, and the L-shape, it is convenient for the staff to rotate and adjust the screw, and the operation is more convenient and labor-saving.
[0049] In some embodiments, the guide tube assembly 21 includes a rotating seat 210 and two guide tubes 211. The rotating seat 210 is a U-shaped plate structure. The rotating seat 210 is arranged on the top side of the base 10. The two guide tubes 211 are respectively arranged on both sides of the rotating seat 210 in the left and right directions. The guide tubes 211 are used for the locking foot anchor rods to pass through. The rotating seat 210 is a U-shaped structure. In this way, the rotating seat 210 is arranged on the top side of the base 10, which will give way to the opening on the top side of the base 10 and will not interfere with the top opening of the base 10. By arranging two guide tubes 211 on the rotating seat 210, the two guide tubes 211 can be used for two locking foot anchor rods to pass through and punch holes at the same time, which meets actual needs and is highly practical.
[0050] The guide tube 211 and the rotating seat 210 may be fixed by welding or by bolts 41 , depending on the actual situation.
[0051] In some embodiments, the rotating seat 210 is rotatably arranged on the top side of the base 10; the angle adjustment assembly 22 includes a mounting plate 220, a nut 221 and a second adjusting screw 222. The mounting plate 220 is mounted on the second side plate 12 by a bolt 41, the nut 221 is mounted on the mounting plate 220, the second adjusting screw 222 is vertically penetrated in the nut 221 and threadedly matched with the nut 221, one end of the second adjusting screw 222 is held against the bottom of the rotating seat 210, and the second adjusting screw 222 rotates along its own axis direction to drive the rotating seat 210 to rotate relative to the base 10. The rotating seat 210 is rotatably mounted on the top side of the base 10, so that under the supporting action of the second adjusting screw 222, the mounting seat can be driven to rotate relative to the base 10, thereby adjusting the angle of the guide tube 211 to meet the drilling requirements of different locking foot anchor rods, and the application range is wider. In addition, the angle adjustment assembly 22 in this solution has a simple structure, a small volume, and is easy to implement.
[0052] The angle of the rotating seat 210 can be fine-tuned between 30°-45°. When the three-step excavation is in progress and the working space is insufficient, the working space can be ensured by adjusting the angle. The second adjusting screw 222 and the nut 221 should be lubricated regularly to maintain them and prolong their service life.
[0053] In addition, hinge holes are correspondingly arranged on the first side plate 11 and the second side plate 12, and a hinge shaft is arranged at the bottom of the rotating seat 210 at a position corresponding to the hinge hole. The hinge shaft passes through the hinge hole, and pins or limiting structures are arranged at both ends of the hinge shaft to prevent the hinge shaft from detaching from the hinge hole.
[0054] In some embodiments, a limiting portion 23 is provided at the bottom of the rotating seat 210 on the first side plate 11 and the second side plate 12, and the limiting portion 23 is used to limit the rotation stroke of the rotating seat 210. By providing the limiting portion 23 on the first side plate 11 and the second side plate 12, the limiting portion 23 can support and limit the rotating seat 210, and limit the stroke of the rotating seat 210.
[0055] It can be understood that when the rotating base 210 is fine-tuned between 30° and 45°, when the rotating base 210 is at 30°, the limiting portion 23 provides a supporting function for the rotating base 210 .
[0056] In addition, after the angle of the guide tube assembly 21 is adjusted, the limiting portion 23 or the second adjusting screw 222 provides adjustment and support capabilities for the rotating seat 210. The first side plate 11 may also be provided with a bolt 41 for auxiliary support of the rotating seat 210. The first side plate 11 is provided with a long strip-shaped adjustment hole 40 along its height direction. The bolt 41 is passed through the adjustment hole 40. The bolt 41 includes a screw and a nut. The nut locks and fixes the screw at a certain position of the adjustment hole 40. By adjusting the position of the bolt 41, the rotating seat 210 is provided with auxiliary support.
[0057] In some embodiments, the surface of the base 10 is coated with an anti-rust layer. The provision of the anti-rust layer prolongs the service life of the base 10 and is not easy to rust.
[0058] Of course, the surfaces of the rotating seat 210, the mounting plate 220 and the mounting box 320 may also be coated with anti-rust paint.
