Description

Technical Field

[0001] This application relates to the technical field of pile foundation testing, and in particular to a pile foundation testing device that is easy to locate stably. Background Technology

[0002] Currently, the main methods for pile foundation testing include static load testing, core drilling, low-strain method, high-strain method, and sonic logging. Existing pile foundation testing instruments are all fixedly mounted on trolleys and pushed into the construction site for testing. Because the types of pile foundations to be tested vary, the corresponding installation height of the detectors also differs, making it cumbersome to use the same testing device due to height limitations. Currently, during pile foundation testing, the detector needs to be moved to a specific location and supported before the testing can proceed.

[0003] Regarding the aforementioned technologies, the inventors believe that when supporting the detector, the supporting ground may be uneven. If the detector is placed directly on an uneven ground, the detection device will tilt, which will compromise the stability of the detector and affect the quality of the detection. Utility Model Content

[0004] In order to achieve stable support for the detector and improve the accuracy of the detection, this application provides a pile foundation detection device that is easy to stabilize and position.

[0005] The pile foundation testing device provided in this application, which facilitates stable positioning, adopts the following technical solution:

[0006] A pile foundation testing device for easy and stable positioning includes a support plate, a detector, and a moving assembly. The detector is disposed on the top surface of the support plate. Several sets of moving assemblies are disposed on the bottom surface of the support plate. Each moving assembly includes a moving sleeve, a moving slide rod, and a universal wheel. The moving sleeve is vertically disposed on the bottom surface of the support plate. The top end of the moving slide rod is slidably disposed in the moving sleeve. The universal wheel is disposed at the bottom end of the moving slide rod. A drive source for driving the moving slide rod to slide is disposed on the moving sleeve. A first support assembly is disposed on the bottom surface of the support plate. The first support assembly includes a first inclined sleeve, a first slide rod, and a first support cylinder. Two first inclined sleeves are inclinedly disposed on the bottom surface of the support plate. The distance between the two first inclined sleeves increases along the direction away from the support plate. One first slide rod is slidably disposed in each first inclined sleeve. One first support cylinder is disposed on each first inclined sleeve. The output shaft of the first support cylinder is disposed parallel to the first inclined sleeve and is connected to the first slide rod for transmission.

[0007] By adopting the above technical solution, the device is pushed to the required position, and the drive source activates the moving slide bar to move within the moving sleeve, thereby leveling the support plate. After leveling the support plate, the first slide bar moves within the first inclined sleeve, with its end contacting the ground, providing stable support for the support plate and reducing the possibility of the detector shaking during use. Through the cooperation of the support plate, detector, and moving components, the movement and fixation of the detector are achieved, providing stable support and improving detection accuracy.

[0008] Optionally, a drive motor is provided on the bottom surface of the support plate, and a sliding block is provided at the top of each of the two first inclined sleeve rods. A drive screw is drivenly connected to the drive motor, and the drive screw is threadedly connected to both sliding blocks. The top surface of the sliding block is slidably fitted against the top surface of the support plate.

[0009] By adopting the above technical solution, the drive motor starts and drives the drive screw to rotate. Under the driving action of the drive screw, the two sliding blocks move along their length direction, thereby realizing the adjustment of the detector's position in the horizontal direction.

[0011] By adopting the above technical solution, the dovetail groove and dovetail strip enable a sliding connection between the sliding plate and the support plate. When fine-tuning of the detector's position is required, the drive source drives the sliding plate to move along the length of the dovetail groove. The combined arrangement of the sliding plate and the first support assembly facilitates fine-tuning of the detector's position in the horizontal direction.

[0012] Optionally, two cylindrical leveling instruments are horizontally arranged on the top surface of the sliding plate, and the two cylindrical leveling instruments are vertically arranged.

[0013] By adopting the above technical solution, two cylindrical level instruments can simultaneously detect the levelness of the detector. Since the two cylindrical level instruments are set vertically, the accuracy of the measurement results is guaranteed.

[0014] Optionally, a second support assembly is provided on the bottom surface of the support plate. The second support assembly includes a second inclined sleeve, a second sliding rod, and a second support cylinder. Two second inclined sleeves are inclinedly arranged on the bottom surface of the support plate, and the line connecting the two second inclined sleeves is perpendicular to the line connecting the two first inclined sleeves. One second sliding rod is provided in each second inclined sleeve, and one second support cylinder is provided on each second inclined sleeve. The output shaft of the second support cylinder is arranged parallel to the second sliding rod and is connected to the second sliding rod for transmission.

[0015] By adopting the above technical solution, when the device needs to be stabilized, the two first sliding rods and the two second sliding rods support the device simultaneously, further improving the structural stability of the device.

[0016] Optionally, the bottom end of the first slide rod is rotatably provided with a first rotating base plate, and the bottom end of the second slide rod is rotatably provided with a second rotating base plate. The first slide rod is provided with a drive source for driving the first rotating base plate to rotate, and the second slide rod is provided with a drive source for driving the second rotating base plate to rotate.

[0017] By adopting the above technical solution, when the first slide rod and the second slide rod are in contact, the first rotating base plate and the second rotating base plate rotate to an angle that is in contact with the ground under the action of the driving source, thereby achieving stable support for the first slide rod and the second slide rod.

[0018] Optionally, both the first rotating base plate and the second rotating base plate are provided with a base pad on their bottom surfaces.

[0019] By adopting the above technical solution, the setting of the base pad improves the support stability of the first rotating base plate and the second rotating base plate.

[0020] Optionally, the movable slide bar is provided with movable scale lines along its length.

[0021] By adopting the above technical solution, the setting of the movable scale line makes it easier for operators to accurately observe the height of the detector.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By adopting the above technical solution, through the cooperation of the support plate, detector and moving components, the movement and fixation of the detector are realized, which has the effect of providing stable support for the detector and improving the accuracy of detection;
