Then, the sliding member is moved relative to the slide rail, and the center rod is driven by the sliding member to move into the embedded pipe. During the movement, the contact member always contacts the inner wall of the embedded pipe. If the embedded pipe is not aligned with the designed center line, the center rod rotates relative to the sliding member; when the center rod contacts the critical piece, it means that the deviation angle of the embedded pipe reaches the maximum allowable deviation angle, and the embedded pipe needs to be laid again.

Detailed Description of the Embodiment

[0026] The following Figures 1-3 is a further detailed description of the present application.

[0027] The embodiment of the present application discloses a device for detecting the central position error of an embedded pipe in a building structure.

[0028] Embodiment 1

[0029] Referring to Figure 1 and Figure 2 , a device for detecting the central position error of an embedded pipe in a building structure includes a base 1, a sliding member 2, a central rod 3 and an abutting member 4. The base 1 is fixedly connected with a slide rail 11, the sliding member 2 is slidably connected to the slide rail 11 along the length direction of the slide rail 11, and the sliding member 2 is arranged perpendicular to the base 1. The central rod 3 is hinged to the sliding member 2 and extends along the length direction of the slide rail 11. A plurality of abutting members 4 are arranged on the circumferential side of the central rod 3, and the plurality of abutting members 4 are arranged at intervals along the circumferential direction of the central rod 3. The end of the abutting member 4 far from the central rod 3 is used for abutting against the inner wall of the embedded member. A critical piece 21 is arranged on the surface of the sliding member 2 for connecting the central rod 3, and the critical piece 21 is arranged to surround the central rod 3 along the circumferential direction.

[0030] After the embedded pipe is laid, move the detection device to the end of the embedded pipe so that the sliding member 2 is arranged perpendicular to the design center line of the embedded pipe, that is, the center rod 3 is coaxially arranged with the design center line of the embedded pipe. Then move the sliding member 2 relative to the slide rail 11, and drive the center rod 3 to move into the embedded pipe by using the sliding member 2. During the movement, the abutting member 4 always abuts against the inner wall of the embedded pipe. If the embedded pipe is not consistent with the design center line, the center rod 3 rotates relative to the sliding member 2; when the center rod 3 abuts against the critical piece 21, it means that the deviation angle of the embedded pipe reaches the maximum allowable deviation angle, and the embedded pipe needs to be re-laid.

[0031] Among them, the end of the abutting member 4 for abutting against the embedded pipe is rotatably connected with a ball 31 so that the rolling friction exists between the abutting member 4 and the inner wall of the embedded pipe, reducing the wear of the abutting member 4 and the embedded pipe.

[0032] Furthermore, the abutting member 4 is detachably connected to the center rod 3 to facilitate replacing the abutting member 4 with different lengths according to the inner diameters of different embedded pipes.

[0033] In this embodiment, the center rod 3 is threadedly connected with a screw tube 32, and a plurality of abutting members 4 are all connected to the screw tube 32 and arranged at intervals along the circumferential direction of the screw tube 32. Thus, the detachable connection between the abutting member 4 and the center rod 3 is realized by the threaded cooperation between the screw tube 32 and the center rod 3, with a simple structure and convenient operation.

[0034] It can be understood that in other embodiments, it can also be that the abutting member 4 is individually threadedly connected to the center rod 3.

[0035] The implementation principle of Embodiment 1 is: after the embedded pipe is laid, select a screw tube 32 connected with an abutting member 4 of a suitable length according to the inner diameter of the embedded pipe, and thread the screw tube 32 onto the center rod 3.

[0036] Then move the detection device to the end of the embedded pipe so that the sliding member 2 is arranged perpendicular to the design center line of the embedded pipe, that is, the center rod 3 is coaxially arranged with the design center line of the embedded pipe. Then move the sliding member 2 relative to the slide rail 11, and drive the center rod 3 to move into the embedded pipe by using the sliding member 2. During the movement, the abutting member 4 always abuts against the inner wall of the embedded pipe. If the embedded pipe is not consistent with the design center line, the center rod 3 rotates relative to the sliding member 2; when the center rod 3 abuts against the critical piece 21, it means that the deviation angle of the embedded pipe reaches the maximum allowable deviation angle, and the embedded pipe needs to be re-laid. If the center rod 3 does not deflect to the connecting piece during the whole movement process, the laying of the embedded pipe meets the requirements.

[0037] Embodiment 2

[0038] Refer to Figure 3 , the difference between this embodiment and Embodiment 1 lies in the different detachable connection structures between the abutting member 4 and the center rod 3.

[0039] In this embodiment, the central rod 3 is connected with a mounting member 5, and a mounting groove 51 is formed on the surface of the mounting member 5. Non-circular sliding cavities 52 are formed on both sides of the mounting member 5. One end of each sliding cavity 52 penetrates through the side wall of the mounting member 5, and the other end penetrates through the wall of the mounting groove 51. An adjusting member 6 is arranged in the mounting groove 51. Adjusting screw holes 61 are formed at both ends of the adjusting member 6, and the two adjusting screw holes 61 at both ends of the adjusting member 6 are respectively communicated with the two sliding cavities 52 on both sides of the mounting member 5. One end of the abutting member 4 passes through the sliding cavity 52 and extends into the adjusting screw hole 61, and an external thread that is in threaded cooperation with the adjusting screw hole 61 is formed on the peripheral side of the end of the abutting member 4.

[0040] Wherein, a plurality of scale lines 41 are arranged on the peripheral side of the abutting member 4, and the plurality of scale lines 41 are arranged at intervals along the length direction of the abutting member 4, so as to facilitate adjusting the position of the abutting member 4 according to the inner diameter of the embedded pipe to be detected.

[0041] The implementation principle of Embodiment 2 is as follows: Before detecting the central position error of the embedded pipe, rotate the adjusting member 6 relative to the mounting member 5, and the adjusting member 6 drives the abutting member 4 to slide along the length direction of the sliding cavity 52, so as to adjust the length of the abutting member 4, so that the abutting member 4 is suitable for embedded pipes with different inner diameters, and the use flexibility of the detection device is improved.

[0042] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
