Description

Technical Field

[0001] The present invention relates to the technical field of pier cap foundation pit settlement detection equipment, and in particular to a pier cap foundation pit settlement detection device and a detection method. Background Art

[0002] In the field of civil engineering and building structure monitoring, the settlement of pier cap foundation pit is directly related to the overall stability and long-term safety of the building. Therefore, accurate and efficient settlement detection technology is of great significance for preventing structural failure and ensuring public safety. However, traditional pier cap foundation pit settlement detection methods face many challenges in practical applications, which are specifically reflected in the following aspects:

[0003] 1. Significant interference from debris: The foundation pit construction site environment is complex, and the surface of the foundation pit is often covered with debris such as stones, soil, and debris. These debris may not only directly hinder the smooth movement of the roller during the roller rolling process of the settlement detection device, but may also cause uneven force on the roller due to uneven distribution, thereby causing deviations in the settlement detection data. Traditional detection devices lack an efficient debris cleaning mechanism, making it difficult to remove these debris in real time and effectively during the detection process, which seriously affects the accuracy and reliability of settlement detection.

[0004] 2. Dust pollution and wear problems: During the foundation pit inspection process, dust on the foundation pit surface is easily lifted up when the roller rolls and enters the detection device with the airflow, especially the guide groove, guide slider and other precision parts. The accumulation of dust not only increases the moving friction of these parts, resulting in a decrease in detection accuracy, but also may accelerate the wear of the parts and shorten the service life of the detection device. In addition, the tiny particles in the dust may also damage the sensitive components such as the sensor of the detection device, further affecting the accuracy of the detection results.

[0005] 3. Increased friction leads to detection errors: As the detection device is used for a longer time, key components such as the guide groove and guide slider gradually wear out due to long-term friction, resulting in increased friction. This not only increases the energy loss during the detection process, but may also affect the stability of the detection data due to changes in friction, making it difficult to ensure the accuracy of the settlement detection results. Traditional detection devices often lack an effective lubrication mechanism, making it difficult to lubricate the guide groove and guide slider in a timely and effective manner, which exacerbates this problem. For this reason, we provide a pier cap foundation pit settlement detection device and detection method. Summary of the invention

[0026] b. When the device is placed above the foundation pit, the settlement of the foundation pit will cause the movable plate to move downward through the vertical fixing rods, n-shaped blocks and rollers; the movement of the movable plate will compress the spring 1, and the deformation degree of the spring 1 will be sensed by the pressure sensor and converted into an electrical signal.

[0030] Beneficial effects of the present invention:

[0031] The present invention arranges a cleaning component, so that during the rolling process of the roller, the shaft rotating rod 1 cooperates with the bevel gear 1 and the bevel gear 2 to drive the plug-in rod to rotate, and then cooperates with the single-groove belt pulley and the double-groove belt pulley to drive the rotating disk to rotate, so as to achieve the cleaning of the foundation pit surface by the brushing soft bristles, avoid the rolling of the roller due to stones and other debris and cause inaccurate detection results, and greatly improve the final settlement detection accuracy.

[0032] The present invention provides a blowing component, so that during the rotation of the plug-in rod, the strip through groove and the guide slider 1 are coordinated to allow the hollow sleeve rod to drive the shaft rotating rod 2 to rotate synchronously, so that the shaft rotating rod 3 drives the induced draft fan to rotate in coordination with the bevel gear 3 and the bevel gear 4.

DETAILED DESCRIPTION

[0043] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0044] like Figure 1-Figure 8 As shown, a pier cap foundation pit settlement detection device proposed in one embodiment of the present invention, the core of the device lies in the transverse movement mechanism. The transverse movement mechanism is mainly composed of a threaded block 1, and the lower end surface of the threaded block 1 is fixedly connected to a hollow box body 2, and a settlement monitor is installed in the hollow box body 2. The settlement monitor is composed of a pressure sensor 3 and a data collector 4, and the two are electrically connected through a wire. The pressure sensor 3 is connected to the movable plate 6 through a spring 5, and the lower part of the movable plate 6 is connected to an axle rotating rod 9 through a vertical fixing rod 7 and an n-type block 8, and a roller 10 is installed on the axle rotating rod 9. In order to ensure the smooth movement of the movable plate 6, a guide slide member 1 is arranged between the hollow box body 2 and the movable plate 6, including a guide slide groove 13 and a guide slide block 2 34. A cleaning assembly is also installed on the n-type block 8, which is composed of a transverse extension plate 11, a rotating rod 12, a rotating disk 13 and a brush-decorated soft bristle 14. The front and back sides of the hollow box body 2 are connected to the blowing components, which are composed of the mounting hole 27, the cross plate 28, the shaft rotating rod 3 29 and the induced fan 30. In addition, the side of the hollow box body 2 is also equipped with a lubrication mechanism, including a placement box body 35, an oil outlet channel 36 and a sponge block 37. Through the above structure, the accurate monitoring of the settlement of the foundation pit of the pier cap is realized, while ensuring the cleaning of the roller 10 and the lubrication of the guide groove 33, thereby improving the detection accuracy and stability.

[0045] Furthermore, the blowing component is connected to the shaft rotating rod 3 29 through the cross plate 28 in the mounting hole 27, and an exhaust fan 30 is installed at one end of the shaft rotating rod 3 29. The shaft rotating rod 2 16 and the shaft rotating rod 3 29 are connected through the transmission structure 2, that is, the bevel gear 3 31 and the bevel gear 4 32, so that the rotation of the shaft rotating rod 2 16 can drive the exhaust fan 30 to rotate, forming a top-down wind flow, which is helpful for heat dissipation and keeping the interior clean; the setting of the blowing component effectively prevents dust from the foundation pit surface from being lifted up and entering the interior of the hollow box body 2, ensuring the accuracy of settlement monitoring.

[0046] Furthermore, the lubrication mechanism is composed of a placement box 35, an oil outlet channel 36, a sponge block 37, a push plate 38 and a push-pull rod 39. One end of the push-pull rod 39 is connected to the push plate 38, and the other end is fixed with a triangular plate 1 40. The rotation of the shaft rotating rod 2 16 pushes the triangular plate 1 40 through the push assembly including the thread groove 41, the thread block 2 42, the connecting frame 43 and the triangular plate 2 44, thereby driving the push plate 38 to push the sponge block 37, releasing the lubricating oil to the oil outlet channel 36, and lubricating the guide slide groove 1 33 and the guide slide block 2 34; the setting of the lubrication mechanism reduces the friction between the guide slide groove 1 33 and the guide slide block 2 34, and further improves the accuracy of the settlement detection.

[0047] Furthermore, the transmission structure 1 includes a bevel gear 19, a bevel gear 20, a single-groove belt pulley 24, a double-groove belt pulley 25 and a linkage belt 26. The rotation of the shaft rotating rod 19 drives the plug-in rod 18 to rotate through the meshing of the bevel gear 19 and the bevel gear 20, and at the same time, the double-groove belt pulley 25 on the plug-in rod 18 is connected to the single-groove belt pulley 24 on the rotating rod 12 through the linkage belt 26, so as to realize the rotation of the rotating rod 12, thereby driving the brush-decorated soft bristles 14 to clean the roller 10; the setting of the transmission structure 1 enables the roller 10 to be automatically cleaned during the rolling process, avoiding inaccurate detection results caused by debris such as stones.

[0048] Furthermore, the transmission structure 2 is composed of a bevel gear 31 and a bevel gear 4 32, which are meshed and connected so that the rotation of the shaft rotating rod 2 16 can drive the rotation of the shaft rotating rod 3 29, thereby realizing the rotation of the induced draft fan 30; the setting of the transmission structure 2 realizes the linkage between the shaft rotating rod 2 16 and the shaft rotating rod 3 29, providing a power source for the blowing component.

[0049] Furthermore, the push assembly is composed of a thread groove 41, a second thread block 42, a connecting frame 43 and a second triangular plate 44. The rotation of the second shaft rod 16 drives the second thread block 42 to move through the threaded connection between the thread groove 41 and the second thread block 42, and then pushes the lower triangular plate 1 40 and the push-pull rod 39 through the connecting frame 43 and the second triangular plate 44 to release the lubricating oil; the setting of the push assembly realizes the linkage between the rotation of the second shaft rod 16 and the release of the lubricating oil, providing a power source for the lubricating mechanism.

[0050] Further, other components of the transverse movement mechanism are described, including a fixing frame 50, a rectangular groove 51, a servo motor 52, a threaded rod 53, a hydraulic telescopic rod 54 and a mounting seat 55. The servo motor 52 drives the threaded rod 53 to rotate, so that the threaded block 1 slides horizontally in the rectangular groove 51 to achieve the transverse movement function. The hydraulic telescopic rod 54 can adjust the height of the entire device, and the mounting seat 55 is used for stable support; the setting of the transverse movement mechanism enables the device to move flexibly above the foundation pit, which provides convenience for settlement monitoring.

[0051] Furthermore, descriptions of the filter screen 49 on the inner wall of the mounting hole 27, the oil filling hole 47 on the upper end of the placement box body 35, and the sealing cover 48 are added. The filter screen 49 is used to prevent dust in the outside air from entering the hollow box body 2, and the oil filling hole 47 and the sealing cover 48 are used to add lubricating oil to the placement box body 35; the provision of the filter screen 49, the oil filling hole 47, and the sealing cover 48 further improves the stability and practicality of the device.

[0052] Furthermore, the structure and working principle of the guide slide 2 are described. The guide slide 2 is composed of the guide slide groove 2 45 and the guide slide plate 46, which is used to prevent the thread block 2 42 from moving with the rotation of the shaft rotating rod 2 16; the setting of the guide slide 2 ensures the stability of the thread block 2 42 during the movement, providing a guarantee for the normal operation of the lubrication mechanism.

[0053] Furthermore, a detection method for a pier cap foundation pit settlement detection device is provided, including the steps of moving a lateral movement mechanism, collecting data of a settlement monitor, cleaning a cleaning component, heat dissipation and cleaning functions of a blowing component, and lubricating a lubricating mechanism. The specific steps are as follows:

[0054] a. The lateral movement mechanism drives the threaded rod 53 to rotate through the servo motor 52 to realize the lateral movement function of the device; at the same time, the hydraulic telescopic rod 54 adjusts the height of the device.

[0055] b. When the device is placed above the foundation pit, the settlement of the foundation pit causes the movable plate 6 to move downward through the roller 10, compressing the spring 5, and the pressure sensor 3 senses the deformation and converts it into an electrical signal. The data collector 4 collects and processes these signals.

[0056] c. The movable plate 6 slides in the guide groove 1 33 through the guide slide block 2 34 , and at the same time, the rotation of the roller 10 drives the rotating rod 12 to rotate through the transmission structure 1, so that the brush bristles 14 clean the roller 10 .

[0057] d. The shaft rod 29 rotates in linkage with the shaft rod 16 through the transmission structure 2, driving the induced fan 30 to rotate, introducing the outside air into the hollow box body 2, forming a top-down wind flow.

[0058] e. The rotation of the shaft rotating rod 16 pushes the triangular plate 40 and the push-pull rod 39 through the pushing assembly to release the lubricating oil and lubricate the guide groove 33.
