Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an automatic detection device for the concrete elevation of pile foundation tops. Background Technology

[0002] During construction, it is common to pour a concrete layer on top of pile foundations. To meet construction requirements, workers must measure the thickness of this concrete layer to ensure the smooth progress of subsequent construction. Traditionally, workers climb to the height of the concrete layer using a suspended platform or scaffolding and then measure its thickness using a measuring ruler. However, this manual measurement method is susceptible to many influencing factors, making it difficult to guarantee accuracy. For example, the concrete layer at the top of the pile foundation is not perfectly square. The shape of the concrete layer makes it difficult for workers to establish a unified measurement reference point, leading to significant discrepancies in the results. Furthermore, the thickness of the concrete layer at the top of the pile foundation is considerable, typically exceeding one meter. It is difficult for one person to measure the thickness using a measuring ruler alone; multiple people are required, making the measurement results easily susceptible to human error and compromising accuracy. Therefore, an automated device is needed to measure the thickness of the concrete layer at the top of pile foundations to meet the required accuracy. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems by designing an automatic detection device for the concrete elevation of pile tops in pile foundations.

[0004] An automatic detection device for the concrete elevation of a pile foundation top includes a pile foundation and a concrete layer at the pile top, and also includes a rangefinder. The rangefinder is mounted on a corresponding bracket and is capable of horizontal rotation and pitch movement on the bracket.

[0005] It also includes two fixing seats, which are respectively installed on the upper and lower surfaces of the concrete layer. Both fixing seats are close to the end face of the concrete layer. Each fixing seat has a through hole that connects the upper and lower surfaces of the fixing seat. A threaded tube is installed in the through hole. One end of the threaded tube is aligned with one end face of the fixing seat, and the other end of the threaded tube extends out of the other end face of the fixing seat. The outer diameter of the threaded tube matches the inner diameter of the through hole, and the outer surface of the threaded tube is fixedly connected to the inner surface of the through hole. A screw is installed in the threaded tube, and the thread on the screw engages with the thread inside the threaded tube. The tip of the screw points to one end of the threaded tube, and the nut of the screw is located outside the other end of the threaded tube.

[0006] The threaded tube has a groove on its outer surface, forming a closed ring around the center line of the threaded tube. A sleeve is provided on the groove, with its inner side embedded in the groove. The sleeve can rotate around the center line of the threaded tube within the groove. A connecting piece is fixedly installed on the outer surface of the sleeve, and the connecting piece has a connecting hole into which a bolt is inserted. The tube also includes a swing plate, one end of which is fitted onto the bolt and fits against the connecting piece, and is tightened with a nut. The other end of the swing plate has a small hole that penetrates the swing plate and communicates with its left and right sides. The length of the small hole is parallel to the lower surface of the fixed base. The tube also includes a hanger rod, one end of which is movably connected to the small hole via a pin. A tag is fixedly installed on the other end of the hanger rod, and the upper edge of the tag is fixedly connected to the other end of the hanger rod. The hanger rod and the tag are located in the same plane. The hanger rod rotates around the pin under the weight of the tag. Targets are provided on the front and rear surfaces of the tag.

[0007] The tag is a circular sheet structure, the target is located at the center of the tag, the diameter of the tag does not exceed five centimeters, and the target at the center of the tag is circular with a diameter of not more than one centimeter.

[0008] Both the boom and the tag are parallel to the end face of the concrete layer.

[0009] The fixing base is fixedly connected to the upper and lower surfaces of the concrete layer by screwing it into the concrete layer with screws and expansion bolts.

[0010] The diameter of the fine hole does not exceed two millimeters, and the fine hole passes through the center of the other end of the swing plate.

[0011] The swing plate is a long strip structure with rounded rectangles.

[0012] The through hole is a round hole, and the threaded tube is a round tube. The inner surface of the through hole and the outer surface of the threaded tube are fixedly connected by welding.

[0013] The fixing base is a plate-like structure in the shape of a disc.

[0014] The through hole is located at the center of the fixing base, and the center line of the through hole coincides with the center line of the fixing base.

[0015] Beneficial effects

[0016] An automatic detection device for the concrete elevation of pile top in pile foundations, manufactured using the technical solution of the present invention, has the following advantages:

[0017] 1. This device ensures that the upper end of the suspension rod is aligned with the edge of the concrete layer by keeping the fine holes flush with the edge of the concrete layer (i.e., in the same horizontal plane). This ensures that the data measured by the rangefinder are all based on a unified reference point, avoiding the influence of the shape of the concrete layer on the measurement results and improving the accuracy of the measurement.

[0018] 2. After the installation of the fixed base is completed, the measurement work can be carried out. During the entire measurement process, there is no need for multiple people to work at height, which avoids the influence of human factors and high-altitude environment on the measurement results and improves the efficiency and convenience of the measurement work.

[0019] 3. The device has a simple and practical structural design. It does not require too many sensors and control devices to ensure the measurement results. The device has low manufacturing cost, is easy to use and maintain, and has strong market competitiveness. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-3 As shown;

[0025] The invention of this application is that it also includes two fixing seats 4, which are respectively installed on the upper and lower surfaces of the concrete layer. Both fixing seats are close to the end face of the concrete layer. The fixing seats are provided with through holes, which connect the upper and lower surfaces of the fixing seats. A threaded tube 5 is installed in the through holes. One end of the threaded tube is aligned with one end face of the fixing seat, and the other end of the threaded tube extends out of the other end face of the fixing seat. The outer diameter of the threaded tube matches the inner diameter of the through hole, and the outer surface of the threaded tube is fixedly connected to the inner surface of the through hole. A screw 6 is provided in the threaded tube. The thread on the screw engages with the thread inside the threaded tube. The tip of the screw points to one end of the threaded tube, and the nut of the screw is located outside the other end of the threaded tube.

[0026] The inventive point of this application also lies in that a groove is provided on the threaded pipe, the groove being on the outer surface of the threaded pipe and forming a closed ring around the center line of the threaded pipe. A circular sleeve 7 is provided on the groove, the circular sleeve being fitted onto the groove with its inner side embedded in the groove. The circular sleeve can rotate around the center line of the threaded pipe within the groove. A connecting piece 8 is fixedly installed on the outer surface of the circular sleeve, the connecting piece having a connecting hole into which a bolt 9 is inserted. The application also includes a swing plate 10, one end of which is fitted onto the bolt and fits against the connecting piece. The oscillating plate is fixed by tightening the nut. A small hole is provided on the other end of the oscillating plate. The small hole passes through the oscillating plate and communicates with the left and right sides of the oscillating plate. The length direction of the small hole is parallel to the lower surface of the fixed base. The oscillating plate also includes a hanging rod 11. One end of the hanging rod is movably connected to the small hole through a pin. The other end of the hanging rod is fixedly installed with a tag 12. The upper edge of the tag is fixedly connected to the other end of the hanging rod. The hanging rod and the tag are located in the same plane. The hanging rod rotates around the pin under the action of the weight of the tag. Targets 13 are provided on the front and rear surfaces of the tag.

[0027] The electronic components used in this technical solution include:

[0028] Rangefinder and its power supply;

[0029] All of the above electronic devices are existing products. The technical solution of this application does not have any special requirements or changes to the structure of the above electronic devices. All of the above electronic devices are conventional electronic devices.

[0030] During the implementation of this technical solution, those skilled in the art need to connect all electrical components and their compatible power supplies through wires, and should select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0031] The inventive point of this application is that the tag is a circular sheet structure, the target is located at the center of the tag, the diameter of the tag does not exceed five centimeters, the target at the center of the tag is circular, and the diameter of the target does not exceed one centimeter; the hanging rod and the tag are both parallel to the end face of the concrete layer; the fixing seat is fixedly connected to the upper and lower surfaces of the concrete layer by screws and expansion bolts; the diameter of the fine hole does not exceed two millimeters, and the fine hole passes through the center of the other end of the swing plate; the swing plate is a long strip structure with rounded rectangles; the through hole is a circular hole, the threaded tube is a circular tube, and the inner surface of the through hole and the outer surface of the threaded tube are fixedly connected by welding; the fixing seat is a plate structure with a disc shape; the through hole is located at the center of the fixing seat, and the center line of the through hole coincides with the center line of the fixing seat.

[0032] In the implementation of this technical solution, workers use a suspended platform to fix two fixed seats to the upper and lower surfaces of the concrete layer, respectively, with the fixed seats close to the end face of the concrete layer, ensuring that the other end of the swing plate is suspended at the end face of the concrete layer. The fixed seat fixed to the upper surface of the concrete layer is designated as fixed seat number one, and the fixed seat fixed to the lower surface of the concrete layer is designated as fixed seat number two. After the fixed seat number one is installed, workers adjust the other end of the swing plate to the end face of the concrete layer, and then move the other end of the swing plate downwards towards the upper edge of the end face of the concrete layer. Continue until the small hole at the other end of the swing plate is in the same plane as the upper edge of the concrete layer. Then tighten the nut to fix the swing plate. The rod will hang naturally under the weight of the pendant, and both the rod and the pendant will be parallel to the end face of the concrete layer. Repeat the above operation, adjusting the other end of the swing plate on the second high fixed seat upwards so that the small hole at the other end of the swing plate is in the same plane as the lower edge of the concrete layer. Then tighten the nut to fix the swing plate. The rod will hang naturally under the weight of the pendant, and both the rod and the pendant will be parallel to the end face of the concrete layer, thus completing the preparation work for measurement.

[0033] The staff adjusted the angle of the rangefinder so that the lens of the rangefinder and the tag were in the same vertical plane. Then, they adjusted the upward angle of the rangefinder so that the lens was aimed at the target in the center of the tag on the first fixing base. The rangefinder displayed the distance between its lens and the target. Then, the staff used a protractor on the bracket to measure the angle between the rangefinder lens and the horizontal plane. Then, they used trigonometric functions to calculate the distance X between the target on the first fixing base and the horizontal plane. The above operation was repeated to calculate the distance Y between the target on the second fixing base and the horizontal plane. Then, the thickness of the concrete layer was obtained using XY.

[0034] To ensure measurement efficiency, the target can be replaced with a photoresistor, and a microcontroller and wireless module can be configured on the base. A laser rangefinder can be selected. When the laser beam of the laser rangefinder shines on the photoresistor, the photoresistor generates an analog signal. The analog signal is converted into a digital signal through digital-to-analog conversion and transmitted to the microcontroller. After receiving the digital signal, the microcontroller sends it to the smart terminal through the wireless module, thereby assisting the staff in calibrating the measurement data and tilt angle of the rangefinder and improving the accuracy of the measurement results.
