[0002] A foundation pit monitoring device is a type of equipment used to monitor the stability and safety of a foundation pit during construction. Foundation pit monitoring is a crucial part of foundation pit engineering construction. It assesses the impact of foundation pit excavation on the surrounding environment and prevents and controls potential foundation pit accidents by regularly or continuously observing and analyzing parameters such as surface settlement, groundwater level, soil stress, and deformation of the support structure around the foundation pit.

[0003] However, when using the foundation pit monitoring device, sometimes the device is too large, making it inconvenient to carry or store, resulting in more time being spent on transportation and making the device less convenient to use. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a foundation pit monitoring device for building engineering.

[0005] This utility model is achieved by the following technical solution: a foundation pit monitoring device for building engineering, including a reinforcement mechanism, a telescopic mechanism and a rotating mechanism, wherein the rotating mechanism is located at the upper end of the telescopic mechanism and the rotating mechanism is located on the surface of the telescopic mechanism;

[0006] The reinforcement mechanism includes a rotating sleeve, with a limiting block engaged on the inner wall of the rotating sleeve. A first support frame is fixedly connected to the lower end of the limiting block. A rotating shaft is fixedly connected to the inner wall of the first support frame. A threaded rod is threadedly connected to the inner wall of the first support frame. An expansion threaded sleeve is threadedly connected to the surface of the threaded rod. A recycling groove is provided on the inner wall of the first support frame. A second support frame is engaged on the surface of the expansion threaded sleeve.

[0007] The above technical solution uses the rotation of the rotating sleeve to limit the angle of the first support frame after rotation, and the threaded rod to rotate into the inner wall of the expansion threaded sleeve to expand and limit the second support frame. This design achieves more convenient angle adjustment and makes it more convenient to use.

[0008] As a further improvement to the above solution, the surface of the second support frame is rotatably connected to the inner wall of the recycling tank, and the surface of the expansion threaded sleeve is fixedly connected to the inner wall of the first support frame.

[0009] As a further improvement to the above solution, the telescopic mechanism includes a support sleeve rod, the inner wall of which is provided with an installation groove, the inner wall of which is rotatably connected with a pulley, the inner wall of which is slidably connected with a telescopic shaft, the inner wall of which is threadedly connected with a limit thread rod, the surface of which is provided with a limit groove, and the surface of which is provided with a sliding groove.

[0010] By using the above technical solution, the rotation of the limiting threaded rod is used to limit the position of the telescopic shaft after it has changed position, which achieves a more convenient effect of fixing the position of the telescopic shaft and the support sleeve rod, thus improving practicality.

[0011] As a further improvement to the above solution, the surface of the pulley is in rolling connection with the inner wall of the groove, and the surface of the limiting threaded rod is engaged with the inner wall of the limiting groove.

[0012] As a further improvement to the above solution, the rotating mechanism includes a rotating block, the upper end of which is fixedly connected to a mounting frame, the inner wall of which is fixedly connected to a connecting rod, and the end of the connecting rod is rotatably connected to a prism.

[0013] The above technical solution, which uses a rotating block to drive the prism to rotate, enables more convenient adjustment of the monitoring angle and makes it more convenient to use.

[0014] As a further improvement to the above solution, the lower end of the rotating block is rotatably connected to the upper end of the support sleeve rod.

[0015] As a further improvement to the above solution, the inner wall of the rotating sleeve is rotatably connected to the surface of the telescopic shaft, and both ends of the rotating shaft are rotatably connected to the inner wall of the telescopic shaft.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model employs a reinforcement mechanism, specifically: rotating the rotating sleeve to the right releases the inner wall's restriction on the limiting block; then pulling the first support frame out from the inner wall of the telescopic shaft to adjust its angle; after the first support frame's angle is adjusted, rotating the rotating sleeve back to re-limit the limiting block, thereby fixing the angle of the first support frame; after pulling it out, rotating the threaded rod reduces the friction limit of the expansion threaded sleeve on the second support frame; then rotating the second support frame to adjust it to a suitable angle, rotating the threaded rod back again to re-expand the expansion threaded sleeve to limit the angle of the second support frame, thus completing the adjustment of the device.

[0018] This utility model incorporates a telescopic mechanism, specifically: the limiting threaded rod is rotated out to disengage it from the inner wall of the lower limiting groove; after releasing the overall limiting of the telescopic shaft, the telescopic shaft is pulled outward; at this time, the pulley allows for smoother extraction; after extraction, the limiting threaded rod is rotated back to re-enter the upper limiting groove, thereby re-limiting the telescopic shaft and fixing the structure. By using the rotation of the limiting threaded rod to limit the telescopic shaft after its position has changed, a more convenient effect is achieved in fixing the position of the telescopic shaft and the support sleeve.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-5 This embodiment of a foundation pit monitoring device for building construction includes a reinforcement mechanism 1, a telescopic mechanism 2, and a rotating mechanism 3. The rotating mechanism 3 is located at the upper end of the telescopic mechanism 2 and on the surface of the telescopic mechanism 2.

[0029] The reinforcement mechanism 1 includes a rotating sleeve 101. A limiting block 102 is engaged with the inner wall of the rotating sleeve 101. A first support frame 103 is fixedly connected to the lower end of the limiting block 102. A rotating shaft 104 is fixedly connected to the inner wall of the first support frame 103. A threaded rod 105 is threadedly connected to the inner wall of the first support frame 103. An expansion threaded sleeve 106 is threadedly connected to the surface of the threaded rod 105. A recycling groove 107 is provided on the inner wall of the first support frame 103. A second support frame 108 is engaged with the surface of the expansion threaded sleeve 106. The design of using the rotation of the rotating sleeve 101 to limit the angle of the first support frame 103 after rotation and the threaded rod 105 to rotate into the inner wall of the expansion threaded sleeve 106 to expand and limit the second support frame 108 achieves more convenient angle adjustment and is more convenient to use.

[0030] The surface of the second support frame 108 is rotatably connected to the inner wall of the recycling tank 107, and the surface of the expansion threaded sleeve 106 is fixedly connected to the inner wall of the first support frame 103.

[0031] The telescopic mechanism 2 includes a support sleeve 201. An installation groove 202 is formed on the inner wall of the support sleeve 201. A pulley 203 is rotatably connected to the inner wall of the installation groove 202. A telescopic shaft 204 is slidably connected to the inner wall of the support sleeve 201. A limiting threaded rod 205 is threadedly connected to the inner wall of the support sleeve 201. A limiting groove 206 is formed on the surface of the telescopic shaft 204. A sliding groove 207 is formed on the surface of the limiting groove 206. The limiting threaded rod 205 is rotated to limit the position of the telescopic shaft 204 after it has changed position, achieving a more convenient effect of fixing the position of the telescopic shaft 204 and the support sleeve 201, thus improving practicality.

[0032] The surface of pulley 203 is in rolling contact with the inner wall of slide groove 207, and the surface of limit thread rod 205 is engaged with the inner wall of limit groove 206.

[0033] The rotating mechanism 3 includes a rotating block 301, with a mounting bracket 302 fixedly connected to the upper end of the rotating block 301. A connecting rod 303 is fixedly connected to the inner wall of the mounting bracket 302, and a prism 304 is rotatably connected to the end of the connecting rod 303. The design of using the rotating block 301 to drive the prism 304 to rotate achieves the effect of more convenient adjustment of the monitoring angle, making it more convenient to use.

[0034] The lower end of the rotating block 301 is rotatably connected to the upper end of the support sleeve rod 201.

[0035] The inner wall of the rotating sleeve 101 is rotatably connected to the surface of the telescopic shaft 204, and both ends of the rotating shaft 104 are rotatably connected to the inner wall of the telescopic shaft 204.

[0036] The implementation principle of a foundation pit monitoring device for construction engineering in this embodiment is as follows: When using the device, first rotate the limiting threaded rod 205 out to disengage it from the inner wall of the lower limiting groove 206. After releasing the overall limiting of the telescopic shaft 204, pull the telescopic shaft 204 outward. At this time, under the action of the pulley 203, it can be pulled out more smoothly. After being pulled out, rotate the limiting threaded rod 205 back to let it enter the upper limiting groove 206, thereby re-limiting the telescopic shaft 204 and fixing the structure. Using the rotation of the limiting threaded rod 205 to limit the telescopic shaft 204 after its position has changed, a more convenient effect of fixing the position of the telescopic shaft 204 and the support sleeve rod 201 is achieved. After the telescopic shaft 204 is pulled out and fixed, rotate the rotating sleeve 101 to the right to release the inner wall's limitation on the limiting block 102, and then the first A support frame 103 is pulled out from the inner wall of the telescopic shaft 204 to adjust its angle. After the angle of the first support frame 103 is adjusted, the rotating sleeve 101 is rotated back to reposition the limiting block 102, thereby fixing the angle of the first support frame 103. After being pulled out, the threaded rod 105 is rotated to reduce the friction limit of the expansion threaded sleeve 106 on the second support frame 108. Then, the second support frame 108 is rotated to adjust to a suitable angle, and the threaded rod 105 is rotated back to re-expand the expansion threaded sleeve 106 to reposition the angle of the second support frame 108, thus completing the adjustment of the device. The design of the first support frame 103 and the second support frame 108 rotating on the inner wall of the telescopic shaft 204 and the telescopic shaft 204 retracting inside the support sleeve rod 201 achieves the purpose of retraction when the device is not in use, reducing the space occupied and making it more convenient to carry.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
