Description

Technical Field

[0001] The invention belongs to the technical field of construction engineering monitoring, and in particular is a construction engineering foundation settlement monitoring device. Background Art

[0002] During the foundation construction process, due to the influence of various factors such as geological conditions, construction methods, and load application, the foundation may experience settlement. Especially when building in soft soil areas, the settlement problem of the foundation is particularly prominent. Large settlement differences can cause damage and collapse of the surface structure, posing a serious threat to the safety and stability of the building. Therefore, settlement monitoring of the foundation is an important part of engineering monitoring.

[0003] A construction engineering foundation settlement monitoring device with announcement number CN114182762B is now disclosed, comprising a mounting plate, a first sliding block, a disc, a first limiting plate, a movable plate and a monitoring equipment body, wherein the surface of the mounting plate is fixedly connected to a support rod, the top of the support rod is rotatably connected to a support plate, the surface of the support plate is provided with a hydraulic rod for driving the first sliding block to slide along its own surface, the surface of the first sliding block is rotatably connected to a connecting plate for driving the disc to rotate, and the bottom of the disc is fixedly connected to an embedded rod for driving the first limiting plate and the movable plate to slide. By setting the sliding plate, since the contact surfaces of the sliding plate and the bottom plate are inclined to each other, when the sliding plate slides to the right, a thrust is applied to the bottom plate on the right side, so that the bottom plate on the right side moves downward to prop up the inclined surface.

[0004] Although the above-mentioned device is provided with a sliding plate, since the contact surfaces of the sliding plate and the bottom plate are inclined to each other, when the sliding plate slides to the right, it will exert a thrust on the bottom plate on the right side, causing the bottom plate on the right side to move downward, propping up the inclined surface and preventing the device from tilting. However, the device has a limitation, that is, it is only suitable for being placed on a completely horizontal ground. Once the ground presents a slope or has uneven conditions, the device cannot be placed stably. On such an uneven ground, the device may shake, tilt or even collapse, thereby affecting its normal function and safety. Therefore, it needs to be improved and optimized. Summary of the invention

[0005] In order to solve the problem in the above background technology that the above device is only applicable to horizontal ground, lacks stability on sloped or uneven ground, and urgently needs to be improved and optimized to enhance its adaptability and safety, the present invention provides a construction engineering foundation settlement monitoring device.

[0006] To achieve the above object, the present invention provides the following technical solution: a construction engineering foundation settlement monitoring device, comprising a bottom plate, a cylindrical mounting block is fixedly installed at the bottom of the bottom plate, and a lifting mechanism is arranged at the bottom of the bottom plate;

[0008] Preferably, two fixed blocks are fixedly installed on the top of the base plate, and a rotating rod 2 is rotatably installed on the side of the two fixed blocks close to each other, a tooth block is fixedly sleeved on the outer wall of the rotating rod 2, and a detection device is fixedly installed on the outer wall of the tooth block, and a protective shell is fixedly installed on the top of the base plate, and the fixed blocks and the detection device are both located inside the protective shell.

[0009] Preferably, there are three groups of lifting mechanisms, and the three groups of lifting mechanisms are identical and are distributed at equal distances around the circumference.

[0010] Preferably, a limiting groove is fixedly installed on the outer wall of the tooth column, and a limiting protrusion is provided on the inner wall of the rectangular sleeve. The limiting groove is adapted to the limiting protrusion and is slidably connected with the limiting protrusion.

[0011] Preferably, rotating blocks are rotatably mounted on the bottoms of the three rectangular sleeves, connecting blocks are fixedly mounted on the bottoms of the three rotating blocks, and supporting blocks are hingedly mounted on the inner walls of the three connecting blocks.

[0012] Preferably, a plurality of rubber strips are fixedly mounted on the bottoms of the three support blocks respectively, and the plurality of rubber strips are designed to be distributed at equal distances.

[0013] Preferably, a curved block is fixedly mounted on one side of the disc close to the mounting frame, and the curved block is meshed with the tooth column.

[0014] Preferably, a hydraulic cylinder is fixedly mounted on the inner wall of the bottom of the cylindrical mounting block, a rack is fixedly mounted on the output shaft of the hydraulic cylinder, the rack penetrates the bottom plate and is slidably connected to the bottom plate, and the rack is meshed with the rack block.

[0015] Preferably, three groups of limit assemblies are arranged on the surface of the cylindrical mounting block, and the limit assemblies include a connecting rod 1 hingedly mounted on the outer wall of the cylindrical mounting block, a connecting rod 2 hingedly mounted on the bottom of the connecting rod 1, and the connecting rod 2 is hinged to the corresponding gear column.

[0016] Preferably, the curve block is spiral-shaped, with a starting point adjacent to the center of the disk and gradually expanding outwards therefrom.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

In addition, the design of the rubber strip provides additional stability and buffering for the device, further improving the reliability of the monitoring results.

[0020] The present invention sets three groups of limit assemblies to limit the lifting range of the tooth column and prevent it from excessive rising or falling, thereby protecting the stability and safety of the entire lifting mechanism. The meshing design of the curve block and the tooth column forms a stable transmission system, which reduces the shaking and tilting caused by external factors, allowing the device to perform long-term and stable monitoring work under harsh environmental conditions, providing strong support for settlement monitoring of the foundation of construction projects.

[0021] The present invention can more accurately control the conversion of the rotation of the disc into the lifting movement of the tooth column through the meshing relationship between the spiral curve block and the tooth column. Due to the gradual expansion of the spiral path, the tooth column can move more smoothly during the lifting process, reducing the impact and vibration caused by sudden changes.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 8 As shown, the present invention provides a construction engineering foundation settlement monitoring device, comprising a base plate 1, a cylindrical mounting block 8 is fixedly mounted at the bottom of the base plate 1, and a lifting mechanism is arranged at the bottom of the base plate 1;

[0033] The lifting mechanism includes a gear column 3 fixedly installed at the bottom of the base plate 1, a rectangular sleeve 2 is slidably installed on the outer surface of the gear column 3, a mounting frame 202 is fixedly installed on the inner wall of the rectangular sleeve 2, a rotating rod 4 is rotatably installed on the outer surface of the mounting frame 202, a disk 5 and a gear 6 are fixedly sleeved on the outer wall of the rotating rod 4, a handle 402 is rotatably sleeved on the outer wall of the rotating rod 4, a connecting rod 401 is hingedly installed on the outer wall of the rotating rod 4, a clamping block 4011 is fixedly installed on the outer wall of the connecting rod 401, and the clamping block 4011 is clamped with the gear 6.

[0034] When the handle 402 is used to rotate the rotating rod 4, the gear 6 will rotate accordingly. As the gear 6 rotates, the rectangular sleeve 2 will move along the tooth column 3, thereby realizing the lifting function. The clamping relationship between the clamping block 4011 and the gear 6 is used to realize the fixing or unlocking function of the gear 6.

[0035] By setting up three groups of identical lifting mechanisms, and the three groups of lifting mechanisms are distributed at equal distances around the circumference, a stable supporting structure is formed. By operating the handle 402 and the connecting rod 401, the height of the tooth column 3 can be easily adjusted to keep the base plate 1 level, so that the device can adapt well to complex terrain such as slopes and unevenness, and can ensure the accuracy and reliability of the monitoring results even under extreme conditions. In addition, the stability of the lifting mechanism is further enhanced by the sliding connection between the limiting groove 301 and the limiting protrusion 201.

[0036] like Figure 1 , Figure 3 As shown, two fixed blocks 10 are fixedly installed on the top of the base plate 1, and a rotating rod 1001 is rotatably installed on the side of the two fixed blocks 10 close to each other. A tooth block 10011 is fixedly sleeved on the outer wall of the rotating rod 1001, and a detection device 11 is fixedly installed on the outer wall of the tooth block 10011. A protective shell 101 is fixedly installed on the top of the base plate 1, and the fixed blocks 10 and the detection device 11 are both located inside the protective shell 101.

[0037] The provision of the protective shell 101 can ensure that the fixed block 10 and the detection device 11 can still work normally under harsh environmental conditions such as wind, rain, dust, etc., and the engagement of the tooth block 10011 with the rack 901 allows the tooth block 10011 to rotate when the rack 901 moves up and down in the vertical direction, thereby adjusting the angle of the detection device 11, thereby more accurately monitoring the settlement changes of the foundation.

[0038] like Figure 1 As shown, there are three groups of lifting mechanisms, and the three groups of lifting mechanisms are identical and are distributed at equal distances around the circumference.

[0039] Three sets of identical lifting mechanisms are distributed equidistantly around the circumference to form a stable support structure, so that the device can better adapt to the ground when placed, and can maintain good stability even on uneven or sloping ground, reducing the possibility of shaking and tilting, thereby improving the accuracy and reliability of the monitoring results.

[0040] like Figures 4 to 5 As shown, a limiting groove 301 is fixedly installed on the outer wall of the tooth column 3, and a limiting protrusion 201 is provided on the inner wall of the rectangular sleeve 2. The limiting groove 301 is adapted to the limiting protrusion 201 and is slidably connected with the limiting protrusion 201.

[0041] Through the sliding connection between the limiting groove 301 and the limiting protrusion 201, the movement of the tooth column 3 in the rectangular sleeve 2 becomes more stable and controllable, effectively preventing the tooth column 3 from shaking or misaligning during the lifting or adjustment process, thereby enhancing the structural stability of the entire device.

[0042] like Figures 1 to 5As shown, rotating blocks 7 are rotatably mounted on the bottom of the three rectangular sleeves 2 , connecting blocks 701 are fixedly mounted on the bottom of the three rotating blocks 7 , and supporting blocks 7011 are hingedly mounted on the inner walls of the three connecting blocks 701 .

[0043] By installing the rotating block 7 at the bottom of the rectangular sleeve 2, the rectangular sleeve 2 and its components such as the gear column 3 can be rotated at a certain angle relative to the ground or the installation foundation to adapt to different ground conditions or monitoring requirements. The connecting block 701 connects the supporting block 7011 structure to provide additional support and adjustment capabilities for the entire device, which may be used to adjust the horizontal position or angle of the monitoring device to adapt to different foundation conditions.

[0044] like Figure 1 to Figure 2 As shown, a plurality of rubber strips are fixedly installed at the bottom of the three support blocks 7011, and the plurality of rubber strips are designed to be distributed at equal distances.

[0045] The design of the rubber strip provides the device with additional stability and cushioning effect. When the device is placed on an uneven ground, the elasticity and flexibility of the rubber strip can effectively absorb and disperse the impact force caused by the uneven ground, reduce the shaking and tilting of the device, and thus improve the accuracy and reliability of the monitoring results.

[0046] like Figures 6 to 8 As shown, a curved block 501 is fixedly mounted on one side of the disc 5 close to the mounting frame 202 , and the curved block 501 is meshed with the tooth column 3 .

[0047] Through the meshing design of the curve block 501 and the tooth column 3, the rotation of the disc 5 can be converted into the lifting movement of the tooth column 3, which not only improves the monitoring accuracy, but also enhances the structural stability of the entire monitoring device, so that a stable transmission system is formed between the disc 5, the curve block 501 and the tooth column 3, reducing the shaking and tilting caused by external factors.

[0048] like Figure 1 to Figure 2 As shown, a hydraulic cylinder 9 is fixedly mounted on the bottom inner wall of the cylindrical mounting block 8, a rack 901 is fixedly mounted on the output shaft of the hydraulic cylinder 9, the rack 901 penetrates the bottom plate 1 and is slidably connected to the bottom plate 1, and the rack 901 is meshed with the gear block 10011.

[0049] Through the precise telescopic movement of the hydraulic cylinder 9, the lifting position of the rack 901 can be regulated. The output shaft of the hydraulic cylinder 9 is fixedly connected to the rack 901, ensuring that when the hydraulic cylinder 9 is working, the rack 901 can smoothly and stably rise or fall along the preset trajectory. During this process, the telescopic force and speed of the hydraulic cylinder 9 can be finely adjusted through the control system to meet the precise requirements for monitoring angle adjustment in different scenarios. The tooth block 10011 is fixedly installed on the outer wall of the rotating rod 1001. As the rack 901 moves vertically, the tooth block 10011 is driven by the meshing force, thereby driving the entire rotating rod 1001 to rotate. Since the rotating rod 1001 is directly connected to the detection device 11, the rotational movement of the tooth block 10011 will be directly converted into the angle adjustment of the detection device 11.

[0050] The angle is adjusted through the precise control of the hydraulic cylinder 9 and the rack 901. The telescopic movement of the hydraulic cylinder drives the rack to move up and down, which is converted into rotational movement after meshing with the tooth block 10011, thereby driving the detection device to adjust the angle. This design not only improves the flexibility of monitoring, but also ensures that accurate monitoring data can be obtained under different foundation conditions. In addition, the design of the rubber strip provides additional stability and buffering for the device, further improving the reliability of the monitoring results.

[0051] like Figures 1 to 3 As shown, three groups of limit assemblies are arranged on the outer surface of the cylindrical mounting block 8, and the limit assemblies include a connecting rod 12 hingedly mounted on the outer wall of the cylindrical mounting block 8, a connecting rod 2 1201 is hingedly mounted on the bottom of the connecting rod 12, and the connecting rod 2 1201 is hinged to the corresponding gear column 3.

[0052] Through the design of three sets of limit assemblies, the connection between the cylindrical mounting block 8 and the gear column 3 becomes more stable, and the limit assemblies can limit the lifting range of the gear column 3 to prevent it from excessively rising or falling, thereby protecting the stability and safety of the entire lifting mechanism.

[0053] like Figure 8 As shown, the curve block 501 is spiral-shaped, with its starting point being close to the center of the disk 5 and gradually expanding outwards therefrom.

[0054] The meshing relationship between the spiral curve block 501 and the tooth column 3 can more accurately control the rotation of the disk 5 to be converted into the lifting movement of the tooth column 3. Due to the gradual expansion of the spiral path, the tooth column 3 can move more smoothly during the lifting process, reducing the impact and vibration caused by sudden changes.

[0055] The working principle and use process of the present invention:

[0056] First, according to the ground conditions on site, such as slopes, unevenness, etc., the lifting mechanism needs to be adjusted to ensure that the bottom plate 1 remains level. Figure 1 Taking the slope as an example, it is necessary to operate two of the three lifting mechanisms to raise and one to lower, so as to achieve the purpose of leveling the bottom plate 1;

[0057] Specific adjustment steps of the lifting mechanism:

[0058] The connecting rod 401 is moved to make the block 4011 located above the rotating rod 4, in preparation for the next rotation operation. The handle 402 is moved clockwise to make the block 4011 engage with the gear 6, so that the gear 6 starts to rotate. The rotation of the gear 6 drives the connecting rod 401 and the disk 5 to rotate together. The curved block 501 on the disk 5 meshes with the gear column 3, thereby driving the gear column 3 to rise.

[0059] If the gear column 3 needs to be lowered, the connecting rod 401 is moved downward, the engagement between the clamping block 4011 and the gear 6 is still maintained, and then the handle 402 is moved counterclockwise to achieve the lowering of the gear column 3 through the opposite rotation direction;

[0060] Braking and positioning of lifting mechanism:

[0061] The connecting rod 401 not only adjusts the lifting of the tooth column 3, but also serves as a brake of the lifting mechanism to position the tooth column 3 to prevent it from sliding in a non-operating state.

[0062] Angle adjustment of the detection device 11:

[0063] When the angle of the detection device 11 needs to be adjusted, the hydraulic cylinder 9 is started, and the output shaft of the hydraulic cylinder 9 drives the rack 901 to move together. The rack 901 engages with the gear block 10011, and the vertical movement of the rack 901 is converted into the rotational movement of the gear block 10011. The rotational movement of the gear block 10011 further drives the detection device 11 to adjust the angle to meet specific detection requirements.

[0064] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0065] 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.
