Description

Technical Field

[0001] The utility model belongs to the technical field of pile foundation static load test, and in particular relates to a pile foundation static load test heap loading mechanical arm. Background Art

[0002] The static load test of pile foundations requires the construction of a reaction platform composed of a large number of test counterweights. During the construction of the reaction platform, hoisting and loading operations must be carried out. Hoisting and loading operations require a hydraulic crane and a sling. Currently, the sling mainly consists of a lifting ring, a wire rope, and a hook. Among them, the lifting ring is suspended on the main hook of the hydraulic crane. The lifting ring is tied with a wire rope, and hooks are configured at both ends of the wire rope. This type of sling has a simple structure and a single function. It has poor adaptability and flexibility and does not have an autonomous adjustment function. It also requires a lot of manual hooking or deconstruction and other frequent operations to cooperate with the hydraulic crane to complete the reaction platform for the static load test of the pile foundation. This not only increases the labor intensity of workers, but also poses a high-risk safety hazard.

[0003] To this end, there is an urgent need to provide a new type of lifting equipment that has good flexibility, can adapt to the requirements of pile foundation static load test hoisting and stacking conditions, and can effectively reduce the labor intensity of workers and effectively improve the safety factor during the operation.

[0009] The slewing bearing is fixedly mounted on the central area of ​​the upper end surface of the fixed arm through its outer ring;

[0010] The shaft at the bottom of the lifting ring is fixedly inserted into the center of the inner ring of the slewing bearing, and realizes rotational cooperation with the fixed arm through the slewing bearing;

[0011] The hook is L-shaped as a whole, with two hooks symmetrically distributed at the outer ends of the two movable arms, and the vertical sections of the two hooks are respectively fixed vertically to the lower base plates of the two movable arms, and the horizontal sections of the two hooks extend towards each other in the same horizontal plane, wherein the horizontal sections serve as plugs, and the cross-section of the plug is rectangular;

[0012] The axial flow fans A and B are symmetrically mounted on the upper parts of both ends of the fixed arm, and their airflow directions form a set angle with the length direction of the fixed arm;

[0014] The controller is installed on the fixed arm and is connected to the camera probe, the electromagnetic reversing valve, the wireless communication module 1, the axial flow fan A and the axial flow fan B respectively.

[0015] Furthermore, in order to improve the overall integration degree and to facilitate the lifting operation, the hydraulic pump station is installed in the central area of ​​the transverse accommodating cavity.

[0016] Furthermore, in order to have mobile power supply capabilities so that the robotic arm can be suitable for a variety of operating conditions, the control unit also includes a battery pack, which is respectively connected to the controller, camera probe, electromagnetic reversing valve, axial flow fan A and axial flow fan B to ensure the supply of electricity.

[0017] As a preference, the controller is a PLC controller.

[0018] Furthermore, in order to effectively reduce the resistance of the movable arm during the sliding process relative to the fixed arm, and at the same time, to improve the smoothness during the sliding process, the fixed arm is provided with a support slide at the bottom of the transverse accommodating cavity; the bottom of the movable arm is provided with a guide roller at the position corresponding to the support slide, and is rollingly connected to the support slide through the guide roller.

[0020] In the present invention, a transverse accommodating chamber is provided through the middle of the fixed arm, and two movable arms are slidably inserted into the transverse accommodating chamber, so that the entire arm has the ability to be retractable. By arranging two telescopic hydraulic cylinders relative to each other in the transverse accommodating chamber, and connecting the piston rod ends of the two telescopic hydraulic cylinders to the inner ends of the two movable arms respectively, the telescopic degree of the two movable arms can be controlled by the telescopic action of the two telescopic hydraulic cylinders, thereby greatly improving the convenience of adjusting the overall length of the mechanical arm and facilitating the rapid connection of the hook with different types of test weights. Since the slewing bearing has high rotation accuracy, extremely low friction and self-locking performance, the shaft body at the bottom of the lifting ring is inserted into the inner ring of the slewing bearing, and the outer ring of the slewing bearing is fixedly installed at the center of the upper end face of the fixed arm, so that the lifting ring can have flexible rotation and self-locking capabilities relative to the fixed arm.

The plug has a rectangular cross-section that fits within the rectangular inner hole of the hanging ring on the counterweight, achieving a stable and reliable connection between the plug and the hanging ring. This prevents lateral shaking of the counterweight during the lifting process, further improving the safety factor during the lifting operation. A camera probe is installed at the center of the lower end of the fixed arm and connected to the controller. This makes it easy to collect image data of the counterweight below through the camera probe, which makes it easy for the controller to realize functions such as image recognition, data measurement, and morphological control.

Specifically, the telescopic action of the two telescopic hydraulic cylinders can be controlled by the electromagnetic reversing valve, and the relative distance between the two hooks can be changed by the position of the two movable arms relative to the fixed arm. The rotation angle of the manipulator arm can also be adjusted by controlling the difference in the direction, speed, and strength of the airflow of the axial flow fan to keep it parallel to the counterweight being hoisted. In this way, the locking and unlocking of the manipulator arm hook and the counterweight hanging ring can be conveniently achieved without human hooking or deconstruction, thereby assisting the crane driver to realize unmanned loading operations.A display terminal with wireless communication module 2 is set in the cab. At the same time, a wireless communication module 2 connected to the controller is set on the robotic arm. It can not only upload the images collected by the camera probe in real time to the display terminal for real-time display, but also can send the calculated data to the display terminal for real-time display after the controller calculates the vertical distance between the robotic arm and the suspended counterweight based on the image data, thereby facilitating the crane driver to accurately control the vertical height of the robotic arm.

[0040] As a preference, the controller is a PLC controller.

[0041] In order to effectively reduce the resistance of the movable arm during the sliding process relative to the fixed arm, and at the same time, to improve the smoothness during the sliding process, the fixed arm 1 is provided with a support slide at the bottom of the transverse accommodating cavity 7; the bottom of the movable arm 2 is provided with a guide roller at the position corresponding to the support slide, and is rollingly connected to the support slide through the guide roller.

[0042] In order to send the images captured by the camera probe in real time to the display terminal in the cab so that the crane driver can observe the position of the manipulator and the counterweight in real time, the crane also includes a display terminal, which includes an input module, a processing module, a display module and a wireless communication module 2.

[0043] In the present invention, a transverse accommodating chamber is provided through the middle of the fixed arm, and two movable arms are slidably inserted into the transverse accommodating chamber, so that the entire arm has the ability to be retractable. By arranging two telescopic hydraulic cylinders relative to each other in the transverse accommodating chamber, and connecting the piston rod ends of the two telescopic hydraulic cylinders to the inner ends of the two movable arms respectively, the telescopic degree of the two movable arms can be controlled by the telescopic action of the two telescopic hydraulic cylinders, thereby greatly improving the convenience of adjusting the overall length of the mechanical arm and facilitating the rapid connection of the hook with different types of test weights. Since the slewing bearing has high rotation accuracy, extremely low friction and self-locking performance, the shaft body at the bottom of the lifting ring is inserted into the inner ring of the slewing bearing, and the outer ring of the slewing bearing is fixedly installed at the center of the upper end face of the fixed arm, so that the lifting ring can have flexible rotation and self-locking capabilities relative to the fixed arm. Two axial fans are symmetrically mounted on the upper surfaces of the fixed arms at both ends. This allows the mechanical arm's spatial angle to be adjusted by controlling the difference in airflow direction, speed, and strength between the two axial fans, thereby maintaining the center of the mechanical arm and the suspended counterweight in a parallel state. A pair of hooks are fixedly connected to each end of the two movable arms, with the plugs of the hooks extending toward each other along the same extension line. This allows the distance between the two hooks to be adjusted by changing the relative distance between the two movable arms, allowing the two hooks to be easily inserted into the two hanging rings of the suspended counterweight, greatly improving the flexibility and convenience of the lifting operation. The plug has a rectangular cross-section that fits within the rectangular inner hole of the hanging ring on the counterweight, achieving a stable and reliable connection between the plug and the hanging ring. This prevents lateral shaking of the counterweight during the lifting process, further improving the safety factor during the lifting operation. A camera probe is installed at the center of the lower end of the fixed arm and connected to the controller. This makes it easy to collect image data of the counterweight below through the camera probe, which makes it easy for the controller to realize functions such as image recognition, data measurement, and morphological control.

Specifically, the telescopic action of the two telescopic hydraulic cylinders can be controlled by the electromagnetic reversing valve, and the relative distance between the two hooks can be changed by the position of the two movable arms relative to the fixed arm. The rotation angle of the manipulator arm can also be adjusted by controlling the difference in the direction, speed, and strength of the airflow of the axial flow fan to keep it parallel to the counterweight being hoisted. In this way, the locking and unlocking of the manipulator arm hook and the counterweight hanging ring can be conveniently achieved without human hooking or deconstruction, thereby assisting the crane driver to realize unmanned loading operations.A display terminal with wireless communication module 2 is set in the cab. At the same time, a wireless communication module 2 connected to the controller is set on the robotic arm. It can not only upload the images collected by the camera probe in real time to the display terminal for real-time display, but also can send the calculated data to the display terminal for real-time display after the controller calculates the vertical distance between the robotic arm and the suspended counterweight based on the image data, thereby facilitating the crane driver to accurately control the vertical height of the robotic arm.

[0044] The robotic arm has a simple structure and multiple degrees of freedom. It can serve as a tool to assist crane drivers in loading, installing, and removing static load test counterweights. It can replace manual loading operations during the construction of static load test reaction systems, significantly reducing the labor intensity of workers and effectively improving the safety factor of operators.

[0045] The driver starts the crane, connects the crane's main hook to the lifting ring of the robotic arm, and then uses the crane to lift the robotic arm to a point 0.5 meters above the target counterweight and stops the crane.

[0046] The camera on the fixed arm captures images and data of the counterweight below and sends them to the controller. The controller uses image recognition technology to identify the position of the counterweight and measure the center position and geometric dimensions of the target counterweight. (The controller can be connected to a mobile phone (display terminal) via a wireless communication module. In this way, the crane operator and test personnel can view real-time image data and measurement data on the mobile phone screen throughout the process.)

[0047] 3. The controller controls the axial flow fans A and B at both ends of the fixed arm to output airflow speeds and strengths in different directions, adjust the spatial angle of the robotic arm, and then control the robotic arm to be parallel to the target counterweight and have their centers coincide with each other;

[0048] 4. The controller calculates the distance between the two hanging rings on the counterweight based on the image data. The controller then controls the solenoid reversing valve to operate, using a pair of telescopic hydraulic cylinders to control the telescopic distance of the two movable arms relative to the fixed arms. By retracting or extending the length of the movable arms, the two hooks are aligned with the outside of the two hanging rings on the counterweight.

[0049] 5. The controller measures the vertical distance between the hook and the counterweight's upper eye and transmits it to the crane operator, who then controls the entire fixed arm to slowly lower so that the hook and the eye are in the same horizontal plane. The crane operator then maintains stability, thus achieving the target alignment between the hook and the counterweight's eye.

[0050] 6. The controller controls the electromagnetic reversing valve to operate, so that the telescopic hydraulic cylinder is synchronously retracted to the set distance. During this process, the horizontal section of the hook (plug) is driven to extend into the inside of the two hanging rings, achieving a reliable connection between the robotic arm and the counterweight. Then, the electromagnetic reversing valve is controlled to work in the middle position, reliably locking the action of the telescopic hydraulic cylinder;

[0051] 7. The crane driver starts the crane and visually controls the shifting of the counterweight. Specifically, the crane driver can first move the target counterweight upward to a suitable height, then move it left and right until the target counterweight is directly in the target position and stop the crane.

[0052] 8. The controller controls the action of the electromagnetic reversing valve to extend a pair of telescopic hydraulic cylinders synchronously, so that the hook and the hanging ring of the target counterweight are automatically separated;

[0053] 9. The crane driver operates the crane, moves the robotic arm to another position or cycles for the next lifting operation.
