Description

Technical Field

[0001] This utility model relates to the field of foundation pit displacement monitoring technology, specifically a smart construction site foundation pit displacement monitoring device. Background Technology

[0002] A deep foundation pit refers to an excavation depth exceeding 5 meters (including 5 meters), or a project with particularly complex geological conditions, surrounding environment, and underground pipelines even if the depth does not exceed 5 meters. Before the construction of a foundation pit project, the construction party should entrust a qualified third-party testing unit to conduct on-site monitoring of the foundation pit project. The monitoring of the foundation pit is generally divided into two parts: monitoring of the foundation pit itself and monitoring of the adjacent environment.

[0003] The existing Chinese utility model patent with publication number CN215522770U discloses a smart construction site foundation pit displacement monitoring device, including a base. A vertical pipe is fixedly connected to the top outer wall of the base. A hydraulic cylinder is installed on the inner wall of the vertical pipe. One end of the piston rod of the hydraulic cylinder is connected to a support rod via screws. A sleeve is slidably connected to the outer wall of the support rod. A sleeve plate is fitted onto the top outer wall of the piston rod. Three rotating shafts are provided on the bottom outer wall of the sleeve plate. A fixed rod is movably connected to the bottom outer wall of each rotating shaft. Three limiting holes are opened on the top outer wall of the base plate. A second spring is connected to the inner wall of each limiting hole via screws. A limiting ring is connected to the outer wall of each second spring via screws. The beneficial effect of this utility model is that the fixing process of the device is controlled by a hydraulic cylinder, and the structure is stable and firm after fixing. This avoids the phenomenon that simple fixing structures lead to poor device stability and easy damage from drops, thus improving the efficiency of foundation pit engineering.

[0004] The aforementioned monitoring device uses a hydraulic cylinder piston rod to move a support rod to achieve the conversion of the support structure. During use, due to the uneven ground near the foundation pit, this method cannot guarantee the support effect, and the equipment's center of gravity is prone to deviating from the center, making it easy to tip over, and the monitoring device cannot maintain a horizontal position. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a smart construction site foundation pit displacement monitoring device, which solves the problems of the device easily tipping over due to deviation of the center of gravity during installation, and the inability of the detector to be in a horizontal state.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A smart construction site foundation pit displacement monitoring device includes a connecting rod, and a monitoring mechanism is installed above the connecting rod.

[0007] A leveling component, located above the connecting rod, is used for leveling.

[0008] A limiting component is located at the bottom of the connecting rod to adjust the height of the leveling component;

[0009] The fixing component includes a limiting frame disposed outside the limiting component, a downward electric actuator fixedly installed below the limiting frame, a pressure bearing fixedly installed at the bottom end of the downward electric actuator, a limiting pin fixedly installed below the pressure bearing, and a guide block movably installed outside the limiting pin.

[0010] Preferably, the leveling assembly includes a limiting plate fixedly installed on the upper end of the connecting rod, a PLC controller fixedly installed above the limiting plate, a housing fixedly installed on the outer side of the limiting plate, and ball joints fixedly installed at the four corners of the limiting plate.

[0011] Preferably, a leveling electric actuator is fixedly installed above the ball joint, and the ball joint is also installed at the top of the leveling electric actuator. A support plate is fixedly installed above the ball joint at the top of the leveling electric actuator.

[0012] Preferably, a spring is fixedly installed on the outer side of the support plate, one end of the spring is fixedly connected to the inner wall of the outer shell, a level sensor is fixedly installed on the bottom of the support plate, and a monitor is fixedly installed on the top of the support plate.

[0013] Preferably, the limiting component includes a limiting cone fixedly installed at the bottom of the connecting rod, a lead screw fixedly installed below the limiting cone, a nut movably installed on the outside of the lead screw, the nut engaging with the threaded structure of the lead screw, and the nut and the lead screw support forming a rotatable connection.

[0014] Preferably, a limiting tube is fixedly installed on the outside of the nut, and a slider is movably installed above the limiting tube. There are four sliders in total, and the sliders and the limiting tube form a sliding connection. The inclination angle of the inner wall of the slider is consistent with the inclination angle of the outer side of the limiting cone. The limiting assembly also includes a support frame fixedly and movably installed on the outside of the connecting rod, and the support frame and the connecting rod form a sliding connection.

[0015] Beneficial effects

[0016] This invention provides a smart construction site foundation pit displacement monitoring device. Compared with the prior art, it has the following advantages:

[0017] (1) The intelligent construction site foundation pit displacement monitoring device, through the setting of the leveling electric push rod, the PLC controller can adjust the extension of the corresponding leveling electric push rod according to the monitoring data of the horizontal sensor. The upper and lower ends of the leveling electric push rod are connected to the limit plate and the support plate respectively through the ball joint, so that the leveling electric push rod can rotate in all directions. The height of the four corners of the support plate is adjusted by the extension and retraction of the leveling electric push rod, so that the support plate is in a horizontal state. The spring can limit the position of the support plate, so that the leveling electric push rod is in a near-vertical state. The monitor can be in a horizontal state by adjusting the extension of the leveling electric push rod at the four corners individually.

[0018] (2) The intelligent construction site foundation pit displacement monitoring device has a guide block. The inner wall of the guide block is provided with a protrusion that fits into the groove structure on the outside of the limit nail. The bottom end of the downward electric push rod is connected to the limit nail through a pressure bearing. The guide block on the outside of the limit nail is fitted into the upper part of the support frame. When the downward electric push rod drives the limit nail to move downward, the limit nail will rotate under the drive of the guide block to penetrate into the ground, thereby improving the fixing effect and preventing the device from tipping over.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a smart construction site foundation pit displacement monitoring device, including a connecting rod 1, and a monitoring mechanism 2 is arranged above the connecting rod 1.

[0027] A leveling assembly 21 is disposed above the connecting rod 1 for leveling. The leveling assembly 21 includes a limiting plate 211 fixedly installed on the upper end of the connecting rod 1. A PLC controller 212 is fixedly installed above the limiting plate 211. A housing 213 is fixedly installed on the outer side of the limiting plate 211. Ball joints 214 are fixedly installed at the four corners of the limiting plate 211. A leveling electric push rod 215 is fixedly installed above the ball joints 214. The ball joints 214 are also installed at the top of the leveling electric push rod 215. A support plate 216 is fixedly installed above the ball joints 214 at the top of the leveling electric push rod 215. A spring 217 is fixedly installed on the outer side of the support plate 216. One end of the spring 217 is fixedly connected to the inner wall of the housing 213. A level sensor 218 is fixedly installed at the bottom of the support plate 216. A monitor 219 is fixedly installed above the support plate 216.

[0028] Specifically, the connecting rod 1 can connect the leveling component 21, the limiting component 22, and the fixing component 23 on the outside of the limiting component 22. The limiting plate 211 can limit the position of the ball joint 214. The PLC controller 212 can adjust the extension of the corresponding leveling electric push rod 215 according to the monitoring data of the horizontal sensor 218. The ball joint 214 enables the upper and lower ends of the leveling electric push rod 215 to form a movable connection with the limiting plate 211 and the support plate 216 respectively, so that the leveling electric push rod 215 can rotate in all directions. The extension and retraction of the leveling electric push rod 215 can adjust the height of the four corners of the support plate 216 respectively, so that the support plate 216 is in a horizontal state. The spring 217 can limit the position of the support plate 216, so that the leveling electric push rod 215 is in a near-vertical state.

[0029] The limiting component 22 is located at the bottom of the connecting rod 1 to adjust the height of the leveling component 21. The limiting component 22 includes a limiting cone 221 fixedly installed at the bottom of the connecting rod 1. A lead screw 222 is fixedly installed below the limiting cone 221. A nut 223 is movably installed on the outside of the lead screw 222. The nut 223 and the lead screw 222 are threaded together, and the nut 223 and the lead screw 222 bracket can form a rotatable connection. A limiting tube 224 is fixedly installed on the outside of the nut 223. A slider 225 is movably installed above the limiting tube 224. There are four sliders 225, and the sliders 225 and the limiting tube 224 form a sliding connection. The inclination angle of the inner wall of the slider 225 is the same as the inclination angle of the outer side of the limiting cone 221. The limiting component 22 also includes a support frame 226 fixedly and movably installed on the outside of the connecting rod 1. The support frame 226 and the connecting rod 1 form a sliding connection.

[0030] Specifically, the limiting cone 221 can restrict the position of the slider 225. The limiting cone 221 and the limiting tube 224 are connected by the lead screw 222 and the nut 223. The limiting tube 224 can restrict the position of the slider 225. A rubber pad is provided on the outer edge of the slider 225. By rotating the upper connecting rod 1, the limiting cone 221 is driven to rotate. Since the surface of the slider 225 is in contact with the inner wall of the support frame 226 in the initial state, when the limiting cone 221 rotates, the slider 225 cannot rotate with the lead screw 222 due to friction. This causes the relative position between the lead screw 222 and the nut 223 to change. The limiting cone 221 moves downward and pushes the slider 225 outward, thereby restricting the relative position between the connecting rod 1 and the support frame 226 to achieve the locking effect.

[0031] The fixing component 23 includes a limiting frame 231 disposed outside the limiting component 22. A downward electric push rod 232 is fixedly installed below the limiting frame 231. A pressure bearing 233 is fixedly installed at the bottom end of the downward electric push rod 232. A limiting pin 234 is fixedly installed below the pressure bearing 233. A guide block 235 is movably installed on the outside of the limiting pin 234.

[0032] Specifically, the limiting frame 231 can restrict the position of the downward electric push rod 232. The bottom end of the downward electric push rod 232 is rotatably connected to the limiting pin 234 through the pressure bearing 233. The guide block 235 on the outside of the limiting pin 234 is fitted into the upper part of the support frame 226. When the downward electric push rod 232 drives the limiting pin 234 to move downward, the limiting pin 234 will rotate under the drive of the guide block 235 to penetrate into the ground, thereby improving the fixing effect and preventing the device from tipping over.

[0033] Specifically, the PLC controller 212 is model DVP-14SS-400F, the leveling electric actuator 215 is model JZN182, the level sensor 218 is model RC-ROUCH, and the pressure-down electric actuator 232 is model TOMUU_U2. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] During operation, the PLC controller 212 adjusts the extension of the corresponding leveling electric actuator 215 based on the monitoring data from the level sensor 218. The ball joint 214 allows the upper and lower ends of the leveling electric actuator 215 to be movably connected to the limit plate 211 and the support plate 216, respectively, enabling the leveling electric actuator 215 to rotate omnidirectionally. The extension and retraction of the leveling electric actuator 215 adjusts the height of the four corners of the support plate 216, keeping the support plate 216 horizontal. The spring 217 restricts the position of the support plate 216, keeping the leveling electric actuator 215 in a near-vertical state. The monitor 219 is kept horizontal by individually adjusting the extension of the four corner leveling electric actuators 215. The inner wall of the guide block 235 is provided with a protrusion that fits into the groove structure on the outside of the limit pin 234. The bottom end of the pressing electric actuator 232 is rotatably connected to the limit pin 234 through the pressure bearing 233. The guide block 235 on the outside of the limit pin 234 is fitted into the upper part of the support frame 226. When the pressing electric actuator 232 drives the limit pin 234 to move downward, the limit pin 234 will rotate under the drive of the guide block 235 to penetrate into the ground, thereby improving the fixing effect and preventing the device from tipping over.
