[0002] With the construction of public infrastructure, in the construction of submarine tunnels, mountain tunnels, bridges and pipelines, in order to ensure the stability and safety of these excavated structures during the continuous excavation process, it is often necessary to use some positioning devices and support devices. The locking foot anchor pipe is one of the commonly used support devices. By fixing the anchor pipe underneath, the structure is fixed and supported.

[0003] In actual construction, due to the lack of professional positioning devices, workers often build locking foot anchor pipes based on past experience.

DETAILED DESCRIPTION

[0029] The present application is further described in detail below with reference to the accompanying drawings.

[0030] Example, see Figure 1 、 Figure 2 and Figure 3, A device for positioning a locking foot anchor pipe, which includes two positioning plates and a guiding pipe 3. Both positioning plates include a web 1 and two side plates 2. The two side plates 2 are fixedly connected to the same side of the web 1. Both positioning plates are in a U-shaped structure and are symmetrically arranged. Preferably, the two positioning plates are made of channel steel. On the outer side walls of the webs 1 of the two positioning plates, guiding pipes 3 are installed. In the centers of the webs 1 of the two positioning plates, step holes 7 are provided. Inside the step holes 7, rotatable connecting members 13 are arranged. One end of the connecting member 13 passing through the outer side wall of the web 1 is fixedly connected to the guiding pipe 3. On the guiding pipe 3, an angle adjustment structure is provided for controlling the horizontal angle of the guiding pipe 3, so as to adjust the horizontal angle of the guiding pipe 3 through the angle adjustment mechanism, that is, to adjust the angle of the locking foot anchor pipe. [[ID=,2]]

[0031] In the example of the present disclosure, the angle adjustment structure includes support plates 8 respectively arranged on both sides of the guiding pipe 3. One side of the support plate 8 is fixedly connected to the guiding pipe 3, and the other side abuts against the web 1. At both ends of the side of the two support plates 8 abutting against the web 2, arc-shaped grooves 10 are provided. On the web 1, four screw rods 9 cooperating with the arc-shaped grooves 10 are installed. One ends of the four screw rods 9 are perpendicularly fixedly connected to the web 1, and the other ends intersect with the tracks of the arc-shaped grooves 10 where they rotate. That is, when the guiding pipe 3 drives the support plate 8 to rotate, the screw rod 9 can move on the track in the arc-shaped groove 10. On the four screw rods 9, butterfly nuts 11 for fastening the support plate 8 and the web 1 are threadedly connected. On the arc-shaped groove 10, arc markings 12 are provided.

[0032] Specifically, during construction, if it is necessary to adjust the angle of the guiding pipe 3, when the position of the guiding pipe 3 is rotated, the screw rod 9 will enter the arc-shaped groove 10, and the angle value coinciding with the arc markings 12 on the arc-shaped groove 10 is the horizontal included angle of the guiding pipe 3. The arc markings 12 are marked with markings including 30° to 45°, so that the horizontal included angle of the guiding pipe 3 can be adjusted between 30° and 45°. And the marked 30° and 45° markings can also enable the guiding pipe 3 to quickly switch between the horizontal included angles of 30° and 45°. The arc markings 12 are also marked with markings at every 5° interval, which can be used to finely adjust the horizontal angle of the guiding pipe 3 during construction.

[0033] In the embodiment of the present disclosure, in order to prevent the angle of the guide tube 3 from changing during construction, thereby affecting the angle change of the locking foot anchor tube and thus affecting the support effect of the locking foot anchor tube, the guide tube 3 is fixed by a butterfly nut 11. However, during construction, the angle of the guide tube 3 may change due to the limitation of the locking force of the butterfly nut 11. The guide tube 3 is a hollow cylinder. An opening is provided on the side wall of the guide tube 3 away from the web 1. A baffle 6 is installed at the opening. A first clip 4 is installed on the baffle 6. A first locking portion 5 that cooperates with the first clip 4 is provided on one end of the guide tube 3 on the web 1. By providing the first clip 4 and the first locking portion 5 that cooperates with the first clip 4, the angle of the guide tube 3 is further locked, that is, the angle of the locking foot anchor tube is prevented from changing, thereby ensuring the support effect of the locking foot anchor tube after installation.

[0034] Specifically, the first locking portion 5 includes a movable buckle 50, a vertical plate 51, a movable frame 52, a spring 53, a handle 54 and a connecting plate 55. One end of the movable buckle 50 is inserted into the inside of the movable buckle 50 through the through hole opened in the movable frame 52. The vertical plate 51 is arranged inside the movable plate, and both ends are movably connected to the movable plate through the long strip through holes opened at both ends of the movable frame 52. One side of the vertical plate 51 is fixedly connected to one end of the movable buckle 50 located inside the movable frame 52. The spring 53 is sleeved on the movable buckle 50 and is located inside the movable frame 52. The end of the movable frame 52 away from the movable buckle 50 is rotatably connected to the handle 54, and the end of the handle 54 close to the movable frame 52 is rotatably connected to the connecting plate 55. The end of the connecting plate 55 away from the handle 54 is fixedly connected to the web.

[0035] In this embodiment, when the two fixing plates are installed at both ends of the channel steel, the two fixing plates need to be fixed. On the two positioning plates, a second clip 4' is installed on the side plate 2 of one positioning plate, and a second locking portion 5' is installed on the side plate 2 of the other positioning plate to cooperate with the second clip 4' for locking the two positioning plates.

[0036] It should be specifically explained that the structures of the first clamping member 4 and the second clamping member 4 ′ and the first locking portion 5 and the second locking portion 5 ′ are the same, which can be clearly seen from the drawings and will not be described in detail here.

[0037] It should be specifically explained that in the embodiment of the present disclosure, the material of the locking foot anchor tube positioning device is preferably stainless steel. Since the locking foot anchor tube positioning device is used in relatively humid environments such as bridge holes and tunnels most of the time, the use of stainless steel can prevent the locking foot anchor tube positioning device from rusting and corroding due to long-term use, thereby increasing the service life of the locking foot anchor tube positioning device.

[0038] In the specific implementation process, first clamp the two positioning plates on the steel frame, and use the second locking part 5' to engage with the second clamping part 4' to fix the two positioning plates to the steel frame. Then, rotate the guide tube 3 to rotate the screw rod 9 to the 45° position, tighten the screw rod 9 entering the arc groove 10 with the butterfly nut 11, and finally lock the guide tube 3 firmly with the movable buckle 50 to the first clamping part 4. When the construction angle of the locking foot anchor pipe does not meet the working conditions of driving in 45°, it is necessary to fine-tune the angle of the guide tube 3. The arc marking line 12 is marked with 30° and 45° and a marking every 5°. Rotate the guide tube 3 according to the changed angle. The angle pointed by the screw rod 9 entering the arc groove 10 is the horizontal angle of the guide tube 3. After the adjustment is completed, fix the support plate 8 and the guide tube 3.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
