[0002] Concrete elevation measuring devices are used to measure the elevation of concrete in the construction of ultra-long pile foundations. However, existing concrete elevation measuring devices still have shortcomings, specifically: they cannot accurately determine the elevation of the concrete layer, and the accuracy of the measurement data is low.

[0003] Therefore, a device for measuring the concrete elevation of ultra-long pile foundations is needed to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a device for measuring the concrete elevation of ultra-long pile foundations, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for measuring the concrete elevation of ultra-long pile foundations includes a measuring box, a measuring mechanism is installed inside the measuring box, a controller is installed on the outer wall of the measuring box, and a storage battery is installed inside the measuring box and above the measuring mechanism.

[0007] The measuring mechanism includes a drive shaft rotatably connected inside the measuring box. Connecting plates are fixedly connected to the top, bottom, and both sides of the drive shaft. A winding sleeve is slidably connected to the outer wall of the connecting plate. A traction rope is wound around the outer wall of the winding sleeve inside the measuring box. A float is fixedly connected to the outer wall of the traction rope below the measuring box. A connecting frame is rotatably connected to the outer wall of the winding sleeve near the traction rope. A pressure sensor is fixedly connected to the bottom of the connecting frame. An inner spring is fixedly connected to the inner outer wall of the connecting plate inside the winding sleeve. An inductive displacement sensor is fixedly connected inside the measuring box above the drive shaft. Servo motors are fixedly connected to both ends of the drive shaft.

[0008] As a preferred embodiment of this utility model, the measuring box is made of ABS plastic, and the controller is connected to the battery by electrical connection.

[0009] As a preferred embodiment of this utility model, the connecting plate, the winding sleeve, and the connecting frame are all made of aluminum alloy. The connecting plate has a C-shaped structure design, and the connection method between the connecting plate, the traction rope, and the measuring box is a sliding connection.

[0010] As a preferred embodiment of this utility model, the traction rope is made of nylon rope, the traction rope passes through and extends to the outside of the measuring box, and the inner spring and the winding sleeve, as well as the servo motor and the measuring box are all fixedly connected.

[0011] As a preferred embodiment of this utility model, the inner spring is provided in multiple sets, and the servo motor, inductive displacement sensor, pressure sensor and controller are all connected electrically.

[0012] As a preferred embodiment of this utility model, two sets of traction ropes and servo motors are provided, and the drive shaft passes through and extends to the outside of the winding sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, a concrete elevation measuring device for ultra-long pile foundations is designed. The measuring mechanism within this device measures the concrete elevation. The measuring box is placed at the location of the ultra-long pile foundation. The controller starts the servo motor, which drives the drive shaft to rotate. An inductive displacement sensor detects the angular displacement of the drive shaft. The rotating drive shaft, through a connecting plate, drives the winding sleeve to rotate. The rotating winding sleeve releases the traction rope, which no longer holds the float. Under the influence of gravity, the float moves downwards and enters the ultra-long pile foundation. During its descent, the float passes through the mud layer and laitance layer and falls onto the concrete layer. When the float lands on the concrete layer, it is supported by the concrete layer, and the float no longer pulls. The traction rope, winding sleeve, and traction cable are no longer under the tension of the float. The winding sleeve moves upward under the push of the inner spring. The upward movement of the winding sleeve drives the connecting frame to rise. The connecting frame no longer presses down on the pressure sensor, and the pressure sensor's measurement data returns to zero. The pressure sensor inputs a shutdown signal to the controller, which shuts down the servo motor. The servo motor no longer drives the drive shaft to rotate. The controller calculates the number of rotations of the drive shaft based on the detected angular displacement, and calculates the length of the released traction rope based on the number of rotations of the drive shaft and the diameter of the winding sleeve, thereby obtaining the elevation of the concrete layer. This solves the problem that existing concrete elevation measuring devices cannot accurately determine the elevation of the concrete layer and have low measurement data accuracy.

[0023] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0024] A device for measuring the concrete elevation of an ultra-long pile foundation includes a measuring box 1, a measuring mechanism 2 is installed inside the measuring box 1, a controller 3 is installed on the outer wall of the measuring box 1, and a storage battery 4 is installed inside the measuring box 1 and above the measuring mechanism 2.

[0025] The measuring box 1 is made of ABS plastic, and the controller 3 is connected to the battery 4 by electrical connection.

[0026] In this embodiment, reference Figure 2 and Figure 3 The measuring mechanism 2 includes a drive shaft 201 rotatably connected inside the measuring box 1. Connecting plates 202 are fixedly connected to the top, bottom, and both sides of the drive shaft 201. A winding sleeve 203 is slidably connected to the outer wall of the connecting plate 202. A traction rope 204 is wound around the outer wall of the winding sleeve 203 inside the measuring box 1. A float 205 is fixedly connected to the outer wall of the traction rope 204 below the measuring box 1. A connecting frame 206 is rotatably connected to the outer wall of the winding sleeve 203 near the traction rope 204. A pressure sensor 207 is fixedly connected to the bottom of the connecting frame 206. An inner spring 208 is fixedly connected to the inner outer wall of the connecting plate 202 inside the winding sleeve 203. An inductive displacement sensor 209 is fixedly connected to the inside of the measuring box 1 above the drive shaft 201. Servo motors 210 are fixedly connected to both ends of the drive shaft 201.

[0027] The connecting plate 202, winding sleeve 203, and connecting frame 206 are all made of aluminum alloy. The connecting plate 202 has a C-shaped structure design. The connection between the connecting plate 202, the traction rope 204, and the measuring box 1 is a sliding connection. The traction rope 204 is made of nylon rope and extends through and out of the measuring box 1. The connection between the inner spring 208 and the winding sleeve 203, as well as the servo motor 210 and the measuring box 1, is a fixed connection. Multiple sets of inner springs 208 are provided. The servo motor 210 and inductive displacement... Sensors 209 and 207 are electrically connected to the controller 3. Two sets of traction rope 204 and servo motor 210 are provided. The drive shaft 201 extends through and beyond the winding sleeve 203. The servo motor 210 drives the drive shaft 201 to rotate. The inductive displacement sensor 209 detects the angular displacement of the drive shaft 201. The rotating drive shaft 201 drives the winding sleeve 203 to rotate via the connecting plate 202. The rotating winding sleeve 203 releases the traction rope 204 and the float 205. Moving downwards under the influence of gravity, the descending buoy 205 enters the extra-long pile foundation. During its descent, the buoy 205 passes through the mud layer and laitance layer and lands on the concrete layer. When the buoy 205 lands on the concrete layer, it is supported by the concrete layer, and the buoy 205 no longer pulls the traction rope 204. The winding sleeve 203 and the traction rope 204 are no longer under the tension of the buoy 205. The winding sleeve 203 moves upwards under the push of the inner spring 208, and the upward movement of the winding sleeve 203 drives the connecting frame 206. As the concrete rises, the connecting frame 206 no longer presses down on the pressure sensor 207, the pressure sensor 207's measurement data returns to zero, and the pressure sensor 207 inputs a shutdown signal to the controller 3. The controller 3 shuts down the servo motor 210, and the servo motor 210 no longer drives the drive shaft 201 to rotate. The controller 3 calculates the number of rotations of the drive shaft 201 based on the detected angular displacement, and calculates the length of the released traction rope 204 based on the number of rotations of the drive shaft 201 and the diameter of the winding sleeve 203, thereby obtaining the elevation of the concrete layer.

[0028] The working process of this utility model is as follows: When the ultra-long pile foundation concrete elevation measuring device designed in this scheme is in operation, the measuring box 1 is placed at the location of the ultra-long pile foundation. The controller 3 starts the servo motor 210, which drives the drive shaft 201 to rotate. The inductive displacement sensor 209 detects the angular displacement of the drive shaft 201. The rotating drive shaft 201 drives the winding sleeve 203 to rotate through the connecting plate 202. The rotating winding sleeve 203 releases the traction rope 204, and the float 205 moves downward under the action of gravity. The descending float 205 enters the ultra-long pile foundation. During the descent, the float 205 passes through the mud layer and the laitance layer and falls onto the concrete layer. When the float 205 falls onto the concrete layer, it is supported by the concrete layer. 5. When the traction rope 204 is no longer pulled, the winding sleeve 203 and the traction rope 204 are no longer pulled by the float 205. The winding sleeve 203 moves upward under the push of the inner spring 208. The upward movement of the winding sleeve 203 drives the connecting frame 206 to rise. The connecting frame 206 no longer presses down on the pressure sensor 207. The pressure sensor 207's measurement data returns to zero. The pressure sensor 207 inputs a shutdown signal to the controller 3. The controller 3 shuts down the servo motor 210. The servo motor 210 no longer drives the drive shaft 201 to rotate. The controller 3 calculates the number of rotations of the drive shaft 201 based on the detected angular displacement, and calculates the length of the released traction rope 204 based on the number of rotations of the drive shaft 201 and the diameter of the winding sleeve 203, thereby obtaining the elevation of the concrete layer.
