[0026] See also Figure 1-4 , the utility model provides a technical solution:

[0027] A pile center positioning device for a steel casing comprises a measuring tube 1 for detecting the column center distance, a first foaming agent block 2 is fixedly connected inside the measuring tube 1, a first magnetic block 3 for fixing the measuring tube 1 is fixedly connected inside the first foaming agent block 2, a steel nail 4 is slidably connected inside the measuring tube 1, a second foaming agent block 5 is fixedly connected inside the measuring tube 1, a second magnetic block 6 for fixing the measuring tube 1 is fixedly connected inside the second foaming agent block 5, and a plurality of 10 cm wide adhesive tapes 7 are bonded to the outside of the measuring tube 1;

[0028] A leveling component 8 for detecting the angle of the measuring tube 1 is arranged inside the measuring tube 1;

[0029] A limiting component 9 for controlling the position of the measuring tube 1 is provided at one end of the measuring tube 1 .

[0030] The measuring tube 1 is a PVC tube.

[0031] Through the coordination of the PVC pipe structure, the technical effect of measuring the pile core through the PVC pipe is achieved, solving the technical problem that the pile core position is not convenient for detection. Although the PVC pipe is relatively light, its strength is very high. It has good compression and crack resistance and can withstand greater pressure under different environmental conditions; PVC pipe has a long service life, and its weather resistance and heat resistance enable it to be used in different climatic conditions and is not easily affected by ultraviolet rays and high temperatures; compared with pipes made of other materials, the manufacturing and installation costs of PVC pipes are relatively low, making it an economical and practical choice.

[0032] A plurality of adhesive tapes 7 are arranged at 200 mm, 800 mm and 1750 mm of the measuring tube 1 .

[0033] Through the coordination of the structure of the adhesive tape 7 , the adhesive tape 7 is red, which is convenient for personnel to observe, and the technical problem that the measuring tube 1 is not convenient for observing the distance is solved.

[0034] The steel nail 4 is arranged at the right end of the leftmost adhesive tape 7 .

[0035] Through the coordination of the steel nail 4 and the measuring tube 1 structure, the technical effect of the steel nail 4 supporting the measuring tube 1 is achieved, and the technical problem of the instability of the measuring tube 1 is solved. The steel nail 4 limiting is a commonly used engineering technology, which can play a role of limiting, fixing or protecting during the operation of machinery or equipment.

[0036] The leveling assembly 8 includes a support rod 81 fixedly installed inside the measuring tube 1, one end of the support rod 81 contacts a mounting block 82, a transparent block 83 is fixedly connected inside the mounting block 82, a cross line 84 is fixedly connected to the outside of the transparent block 83, two limit blocks 85 are fixedly connected to the side wall of the mounting block 82, a pressing rod 86 is slidably connected inside the two limit blocks 85, one end of the mounting rod is fixedly connected to a moving plate 87, two tension springs 88 are arranged on the side wall of the moving plate 87, and a limit rod 89 is fixedly connected to the side wall of the moving plate 87.

[0037] Through the cooperation of structures such as the support rod 81 and the mounting block 82, the support rod 81 supports the mounting block 82. A transparent block 83 is fixed inside the mounting block 82. The transparent block 83 is filled with green liquid. The water level line of the liquid is used in conjunction with the cross line 84 to detect the angle of the measuring tube 1. The position of the limit rod 89 is controlled by the pressing rod 86 and the moving plate 87. The tension spring 88 pulls the moving plate 87 and the limit rod 89 away from the mounting block 82, so that the limit rod 89 is stuck in the measuring tube 1. The technical effect has solved the technical problem that when the measuring tube 1 is uneven, the detection is prone to errors.

[0038] A limiting hole adapted to the limiting rod 89 is provided inside the measuring tube 1 , and the limiting rod 89 and the moving plate 87 are respectively slidably connected to the inside of the limiting block 85 .

[0039] Through the cooperation between the limiting rod 89 and the limiting hole structure, the limiting rod 89 is inserted into the limiting hole to limit the mounting block 82, thereby solving the technical problem that the mounting block 82 is inconvenient to install.

[0040] The limit assembly 9 includes a mounting shell 91 fixedly mounted on the side wall of the measuring tube 1, a screw 92 is rotatably connected inside the mounting shell 91, one end of the screw 92 passes through the mounting shell 91 and is fixedly connected to a knob 93, the knob 93 is rotatably connected to the outside of the mounting shell 91, and the outside of the screw 92 is threadedly connected to a limit frame 94.

[0041] By cooperating with structures such as the mounting shell 91 and the screw 92, the mounting shell 91 can be used to install components such as the screw 92. By rotating the knob 93, the screw 92 is driven to rotate, and threaded movement occurs between the screw 92 and the limit frame 94. The limit frame 94 is tightly attached to the steel pipe, so that the lower end of the measuring tube 1 is parallel to the steel pipe, which solves the technical problem that the measuring tube 1 may tilt during use.

[0042] The limiting frame 94 is U-shaped, and the limiting frame 94 is slidably connected to the measuring tube 1, the first foaming agent block 2, and the mounting shell 91 respectively.

[0043] Through the coordination of the limit frame 94 and the measuring tube 1 and other structures, the limit frame 94 is slidably connected to the measuring tube 1, the first foaming agent block 2 and the mounting shell 91 respectively, which has the technical effect of limiting the limit frame 94 and solves the technical problem of the lack of limit of the limit frame 94.

[0044] Working principle: When the utility model is used, the measuring tube 1 can be quickly located at the 800mm position of the vertical pole by adsorbing it horizontally on the horizontal pole; the tape 7 at the 200mm position of the bottom is used to locate the position of the sweeping pole, and the steel nail 4 at the 250mm position is placed on the horizontal pole to fix the measuring tube 1. The first magnetic block 3 and the second magnetic block 6 inside the measuring tube 1 are adsorbed on the vertical pole, and the position can be quickly located at the upper 1500mm position of the horizontal pole. In this way, one person can complete the operation, which greatly improves the positioning accuracy and speed, and ensures both the installation quality and the installation efficiency.

[0045] A transparent block 83 is fixed inside the mounting block 82, and a green liquid is filled inside the transparent block 83. The water level of the liquid is used in conjunction with the crosshairs 84 to detect the angle of the measuring tube 1. The position of the limit rod 89 is controlled by the pressing rod 86 and the moving plate 87. The tension spring 88 pulls the moving plate 87 and the limit rod 89 away from the mounting block 82, so that the limit rod 89 is stuck in the measuring tube 1, and the mounting block 82 is installed.

[0046] The knob 93 is rotated to drive the screw rod 92 to rotate, and a threaded motion occurs between the screw rod 92 and the limit frame 94. The limit frame 94 is tightly attached to the steel pipe, so that the lower end of the measuring tube 1 is parallel to the steel pipe.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
