The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] Reference Figure 1 and Figure 2 The preferred embodiment of the utility model is a locking foot anchor pipe positioning tool, comprising: a clamp seat 10 that can be opened and locked, a locking device that can be unlocked for maintaining the clamp seat 10 in a locked state is provided on the clamp seat 10, and the clamp seat 10 is used to be clamped and fixed on the vertical steel section in the tunnel; a guide cylinder 30 is fixed on the clamp seat 10, and the inner hole of the guide cylinder 30 can be used for a small catheter to pass through; when the clamp seat 10 is clamped and fixed on the vertical steel section in the tunnel, the guide cylinder 30 is located on the side of the steel section, and the guide cylinder 30 is inclined downward at an angle relative to the horizontal plane from the head end to the tail end. When the locking foot anchor pipe positioning tool is in use, the clamp seat 10 can be directly clamped and fixed on the vertical steel section in the tunnel, and the guide cylinder 30 is also fixed at the required position and angle. The inner hole of the guide cylinder 30 can then be used to guide the construction equipment and the small conduit, which can effectively reduce the deviation and misalignment of the construction equipment and the small conduit, ensure the construction accuracy and quality, effectively reduce the safety risks caused by the slippage of the construction equipment and the small conduit, and ensure the safety of the construction personnel.

[0027] According to the custom and general understanding in this field, those skilled in the art can understand that the head end of the guide cylinder 30 refers to the end of the guide cylinder 30 that the construction equipment or small catheter first enters during the construction operation, and the tail end of the guide cylinder 30 refers to the other end of the guide cylinder 30.

[0028] As a preferred embodiment of the utility model, it may also have the following additional technical features:

[0029] In this embodiment, when the clamp 10 is clamped and fixed on the vertical steel section in the tunnel, the guide cylinder 30 is tilted downward from the head end to the tail end relative to the horizontal plane at an angle of 30 to 35 degrees, which can adapt to commonly used construction angles and is convenient to use. In other embodiments, the inclination angle of the guide cylinder 30 can also be flexibly adjusted as needed, and is not limited to this.

[0030] In this embodiment, there are two guide cylinders 30. When the clamping seat 10 is clamped and fixed on the vertical steel in the tunnel, the two guide cylinders 30 are respectively located on both sides of the steel, and can simultaneously position the construction of the small conduits on both sides of the steel, without repeatedly disassembling and assembling the locking foot anchor pipe positioning tool, which is more convenient to use and helps to improve construction efficiency. In other embodiments, the number and distribution of the guide cylinders 30 can also be flexibly adjusted as needed.

[0031] In this embodiment, the clamp seat 10 includes two clamp arms 11, and the tail ends of the two clamp arms 11 are pivoted together through a pivot shaft 12 so that the two clamp arms 11 can swing relative to each other to open and lock. The locking device includes a locking screw 21 connected to the two clamp arms 11 and a locking nut 22 screwed on the locking screw 21. The locking nut 22 can push the two clamp arms 11 to swing relative to each other along the rotation of the locking screw 21. The clamp seat 10 and the locking device have simple and reliable structures, and are easy to manufacture and operate. In other embodiments, the clamp seat 10 can also adopt other commonly used clamping structures, for example, the two clamp arms 11 can be opened and locked by relatively sliding activities, and the locking device can also adopt other commonly used locking structures such as buckles and latches, but is not limited to this.

[0032] In this embodiment, a handle is provided on the locking screw 21 and / or the locking nut 22, which is convenient for operation without the aid of tools and is easy to use.

[0033] In this embodiment, the handle includes a handle seat 23 and a handle rod 24. The handle seat 23 is connected to the locking screw 21 and / or locking nut 22 corresponding to the handle. A sliding hole adapted to the handle rod 24 is provided on the handle seat 23. The handle rod 24 can be slidably inserted into the sliding hole. Limiting bosses 241 are respectively provided at both ends of the handle rod 24. The sliding hole can prevent the limiting bosses 241 from passing through. Since the steel section is usually closer to the inner wall of the tunnel and the operating space is small, the handle in this embodiment can flexibly adjust the position to avoid obstacles by sliding the handle rod 24 along the sliding hole, which is more flexible and convenient to use. In this embodiment, the handle seat 23 is fixed on the locking screw 21. One end of the locking screw 21 can be rotatably set on one clamp arm 11. A nut screwed on the locking screw 21 is provided on the other clamp arm 11. In this way, when the locking screw 21 is rotated by the handle, one clamp arm 11 can be driven to swing toward the other clamp arm 11 to achieve locking. In other embodiments, the locking screw 21 and the locking nut 22 may also be arranged in other commonly used ways, but are not limited thereto.

[0034] In this embodiment, a clamping groove 13 is respectively provided on the inner side of each clamping arm 11 , and the clamping groove 13 is adapted to the flange of the steel section, which helps to prevent the clamping arm 11 from swinging and is more stable.

[0035] The inner wall of the slot 13 is padded with a cushion to reduce damage to the clamp arm 11 and the steel, and also to increase friction and reduce the sliding of the clamp seat 10 along the steel, making it more stable and reliable. The cushion can be made of common materials such as rubber.

[0036] An elastic device is provided between the two clamping arms 11, and the elastic device is used to drive the two clamping arms 11 to swing relative to each other in the direction of locking the clamping seat 10, so as to facilitate the operation of the clamping seat 10. The elastic device can adopt a common elastic structure such as a torsion spring and a tension spring.

[0037] In this embodiment, the guide tube 30 is detachably fixed on the clamping seat 10, so that it is convenient to replace the guide tubes of different sizes and inclination angles as needed, and the application is wider and more flexible and convenient to use. In this embodiment, the guide tube 30 is detachably mounted on the clamping seat 10 by fixing screws 25, and is not easy to loosen. In other embodiments, the guide tube 30 can also be detachably mounted on the clamping seat 10 by other common structures such as buckles, and is not limited to this.

[0038] Under the premise that no conflict occurs, those skilled in the art may freely combine and superimpose the above-mentioned additional technical features.

[0039] The above description is only a preferred implementation mode of the present utility model. Any technical solution that achieves the purpose of the present utility model by basically the same means belongs to the protection scope of the present utility model.
