Description

Technical Field

[0001] The present application relates to the technical field of foundation pit detection and calibration devices, and in particular to a foundation pit detection and calibration device that is easy to position. Background Art

[0002] The foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings on site, and waterproofing and drainage work should be done. If the excavation is not deep, the side slope can be used to make the earth slope stable. The slope size is determined according to relevant construction regulations. If the excavation is deeper or there are buildings nearby, the foundation pit wall support method and shotcrete wall protection method can be used. Large foundation pits even use underground continuous walls and column-type bored cast-in-place pile interlocking methods to prevent the outer soil layer from collapsing. During the excavation process of the foundation pit, in order to keep the excavation depth of the foundation pit consistent, it is often necessary to detect and calibrate the excavation depth of the foundation pit.

[0003] When the existing foundation pit is used to detect and calibrate the excavation depth, the traditional method is to manually hold a ruler and go down into the foundation pit, and then use a level to observe the scale of the ruler to detect and calibrate the depth of the foundation pit. This method is often affected by manual operation and has large errors and is also dangerous for manual entry into the foundation pit. Therefore, a method of setting up a bracket on the top of the foundation pit and moving a laser rangefinder on the bracket to detect and calibrate the depth of the foundation pit is widely used;

[0004] However, when using a laser rangefinder to detect and calibrate the depth of a foundation pit, the width of the foundation pit is first dug out during the excavation process of the foundation pit at the construction site, and then the length of the foundation pit is dug out little by little. The length of the bracket used to support the mobile laser rangefinder is often fixed. This results in the need to replace mobile brackets of different lengths to move the laser rangefinder when detecting and calibrating the foundation pit. The replacement operation is troublesome and inconvenient. Therefore, those skilled in the art provide a foundation pit detection and calibration device that is easy to locate to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] The present application embodiment discloses a foundation pit detection and calibration device that is convenient for positioning. Figure 2 Figure 3 A foundation pit detection and calibration device convenient for positioning comprises a foundation pit body 1 and two supporting slide rails 2, wherein the two supporting slide rails 2 are respectively located on both sides of the top of the foundation pit body 1, and further comprises

[0025] A positioning detection mechanism 3, which is located between the two support rails 2, and is used to perform positioning detection depth on different areas in the foundation pit body 1;

[0026] Two size adjustment mechanisms 6, which are respectively located at one end of the two supporting rails 2, and are used to adjust and change the size length of the supporting rails 2;

[0027] The size adjustment mechanism 6 includes an extended slide rail 601 and a limit assembly 8, one end of the extended slide rail 601 is mounted on one end of the support slide rail 2 through a rotating folding assembly 7, and the limit assembly 8 is mounted on the other end of the support slide rail 2;

[0028] The rotating and folding assembly 7 includes a rotating groove 701, a rotating support rod 702, a rotating block 703 and two torsion springs 704. The rotating groove 701 is opened at one end of the supporting slide rail 2, and the two ends of the rotating support rod 702 are fixedly connected to the two ends of the rotating groove 701. One end of the extended slide rail 601 is rotatably connected to the middle part of the rotating support rod 702 through the rotating block 703. The two ends of the two torsion springs 704 are respectively fixedly connected to one end of the rotating groove 701 and one end of the rotating block 703.

[0029] The limiting assembly 8 includes two limiting rotary pieces 801, two limiting buckles 802 and two limiting slide grooves 803. The two limiting rotary pieces 801 are symmetrically rotatably connected to the other end of the supporting slide rail 2. The two limiting buckles 802 are respectively fixedly connected to one end of the two limiting rotary pieces 801. The two limiting slide grooves 803 are symmetrically opened at the other end of the extended slide rail 601, and the two limiting slide grooves 803 are matched with the two limiting buckles 802.

[0030] In this embodiment, firstly, the two limit rotating pieces 801 are rotated to drive the two limit buckles 802 to slide out of the two limit sliding grooves 803 opened at one end of the extended slide rail 601. At this time, the two torsion springs 704 provide a force to force the rotating block 703 to rotate on the side wall of the rotating support rod 702. The rotating block 703 rotates to drive the extended slide rail 601 connected thereto to rotate and open to dock with one end of the supporting slide rail 2. In this way, the length of the supporting slide rail 2 can be increased by docking, and at the same time The rotation block 703 is supported by the rotating support rod 702 to drive the extended slide rail 601 to rotate and fold the support slide rail 2, and then the limiting rotary piece 801 is rotated to drive the limiting buckle 802 to slide into the provided limiting slide groove 803 to limit and fix the extended slide rail 601. In this way, the length of the support slide rail 2 can be shortened by folding, thereby facilitating the adjustment of the length of the support slide rail 2 according to the needs of use, and facilitating the detection and calibration of the foundation pit with increasing length.

[0031] Furthermore, the positioning detection mechanism 3 includes a laser rangefinder 301, a lateral moving component 4 and a vertical moving component 5, the lateral moving component 4 is mounted on the side walls of the two supporting slide rails 2, and the top end of the laser rangefinder 301 is mounted on one end of the lateral moving component 4 through the vertical moving component 5;

[0032] The lateral movement assembly 4 includes two first sliders 401 and two first fastening bolts 402. The two first sliders 401 are respectively slidably connected to the side walls of the two supporting slide rails 2. The tops of the two first sliders 401 are provided with threaded holes. The two first fastening bolts 402 are respectively rotatably connected to the tops of the two first sliders 401 by fitting with the threaded holes.

[0033] The vertical moving assembly 5 includes a vertical slide rail 501, a second slider 502 and a second fastening bolt 503. The vertical slide rail 501 is fixedly connected between the two first sliders 401. The top of the laser rangefinder 301 is slidably connected to the side wall of the vertical slide rail 501 through the second slider 502. The second fastening bolt 503 is rotatably connected to the top of the second slider 502.

[0034] After the length is increased on the basis of the above embodiment, the first fastening bolt 402 is rotated to rotate and move upward at the top of the first slider 401, thereby loosening the first slider 401. At this time, the first slider 401 is slid to move horizontally on the supporting slide rail 2, thereby driving the laser rangefinder 301 to move horizontally in the foundation pit to adjust the detection position. At the same time, the second fastening bolt 503 is rotated to rotate and move upward at the top of the second slider 502, thereby loosening the second slider 502. At this time, the second slider 502 is slid to move vertically on the vertical slide rail 501, thereby driving the laser rangefinder 301 to move vertically in the foundation pit. The detection position is adjusted dynamically. After the detection position is adjusted, the first fastening bolt 402 is rotated to rotate it downward and abut against the top of the supporting slide rail 2, thereby limiting and fixing the first slider 401. The second fastening bolt 503 is rotated to rotate it downward and abut against the top of the vertical slide rail 501, thereby limiting and fixing the second slider 502. The laser rangefinder 301 can be positioned and fixed, thereby detecting the depth of the foundation pit. In this way, the detection position of the laser rangefinder 301 can be adjusted and positioned by cooperating with each other through lateral movement or vertical movement, thereby achieving the effect of positioning and detecting different points in the foundation pit.

[0035] The implementation principle of the foundation pit detection and calibration device which is convenient for positioning in the embodiment of the present application is as follows: when in use, when the length of the foundation pit is excavated, the two limit rotary plates 801 are rotated to drive the two limit buckles 802 to slide out from the two limit slide grooves 803 opened at one end of the extended slide rail 601. At this time, the two torsion springs 704 provide a force to force the rotating block 703 to rotate on the side wall of the rotating support rod 702. The rotating block 703 rotates to drive the extended slide rail 601 connected thereto to rotate and open to dock with one end of the supporting slide rail 2. In this way, the length of the supporting slide rail 2 can be increased through docking, thereby effectively facilitating the adjustment of the length of the supporting slide rail 2 according to the needs of use, without the need to replace the supporting slide rails 2 of different lengths. The operation is simple, convenient, time-saving and labor-saving, and is convenient for the purpose of detecting and calibrating the foundation pit with increasing length. Secondly, after the length is increased, the first fastening bolt 402 is rotated to rotate and move upward at the top of the first sliding block 401, thereby loosening the first sliding block 401. At this time, by sliding the first The slider 401 is moved horizontally on the supporting slide rail 2, thereby driving the laser rangefinder 301 to move horizontally in the foundation pit to adjust the detection position. At the same time, the second fastening bolt 503 is rotated to rotate upward on the top of the second slider 502 to loosen the second slider 502. At this time, the second slider 502 is slid to move vertically on the vertical slide rail 501, thereby driving the laser rangefinder 301 to move vertically in the foundation pit to adjust the detection position. After the detection position is moved and adjusted, the first fastening bolt 402 is rotated to rotate upward. The first slider 401 is limited and fixed by moving downward and abutting against the top of the supporting slide rail 2. By rotating the second fastening bolt 503 to rotate it downward and abut against the top of the vertical slide rail 501, the second slider 502 is limited and fixed. The laser rangefinder 301 can be positioned and fixed to detect the depth of the foundation pit. In this way, the detection position of the laser rangefinder 301 can be adjusted and positioned by cooperating with each other through lateral movement or vertical movement, thereby achieving the purpose of effectively facilitating positioning and detection of different points in the foundation pit.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
