Herein, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.

[0026] In the technical solutions of the present application, the acquisition, storage, use, processing, etc. of data all comply with the relevant regulations of national laws and regulations.

[0027] Figure 1 Schematic diagram of the trapezoidal K block transfer system in the embodiment of the present invention. The system includes: a support device 01, a crane 02, a transport vehicle 03, and a control center 04. Figure 2 Actual diagram of the transportation of segments and K blocks in the embodiment of the present invention. As Figure 2 shown, the K block, as a key component in the segments, is usually placed above the larger segments during transportation due to its small volume. And in the specific transfer operation. Figure 3 Schematic diagram of the transportation of segments and K blocks in the embodiment of the present invention. The isosceles trapezoidal object located at Figure 3 the middle position of the third column is the K block. The K block is the last segment to be lifted. Since the K block has a small volume, if it is directly placed between the two segment pillows of the transport vehicle, the K block segment will tilt. Figure 3 The cylinders in the first column and the second column are two segment pillows. To solve the problem that the K block segment will tilt, the embodiment of the present invention proposes a trapezoidal K block transfer system, wherein,

[0028] The support device includes two strut structures, a driving device, and an internal connection structure. The two strut structures are connected to the driving device through the internal connection structure. The support device is installed on the transport vehicle and is arranged between the two segment pillows of the transport vehicle; after confirming that the type of the K block is a trapezoidal K block based on the contour information of the K block, the driving device is used to drive the two strut structures to rise according to the control instruction issued by the control center, and support the K block through the two strut structures;

[0029] The crane 02 is used to grasp and release the K-block according to the control instructions issued by the control center 04;

[0030] The transport vehicle 03 is used to transport the K-block to the designated position according to the control instructions issued by the control center 04.

[0031] In one embodiment, the control center 04 is specifically used for:

[0032] Locate the K-block, control the crane to move above the position of the K-block, and perform the grasping and releasing operation on the K-block.

[0033] In one embodiment, the two segment supports of the transport vehicle 03 are used to support the segments.

[0034] In one embodiment, the two pillar structures of the support device 01 are arranged between the two segment supports of the transport vehicle, and the maximum installation distance between the two pillar structures is less than the short side distance of the trapezoidal K-block.

[0035] In the embodiment of the present invention, a control method for a trapezoidal K-block transfer system is also provided as described in the following embodiments. Since the principle of the device for solving problems is similar to that of the trapezoidal K-block transfer system, the implementation of this method can refer to the implementation of the trapezoidal K-block transfer system, and the repeated parts will not be described again.

[0036] Figure 4 The flowchart of the control method for the trapezoidal K-block transfer system in the embodiment of the present invention is applied to the control center. The method includes:

[0037] Step 401: Issue a raising instruction to the support device, control the two pillar structures in the support device to rise, and support the K-block;

[0038] Step 402: Issue a grasping instruction to the crane, control the crane to move above the position of the K-block, and grasp the K-block;

[0039] Step 403: Issue a transportation instruction to the transport vehicle, control the transport vehicle to transport the K-block to the designated position.

[0040] The transfer operation of the K-block in the actual application process of the embodiment of the present invention is as follows:

[0041] 1. Initialize the segment crane and enter the segment automatic control mode.

[0042] 2. Based on the radars installed on the top and around the trailer, perform multi-radar point cloud acquisition, data fusion, and segment identification on the segments on the segment vehicle.

[0043] 3. Determine whether there are segments or K-blocks. If so, determine again whether the current object to be grasped is a segment or a K-block. If it is a K-block, enter the K-block transfer mode; otherwise, enter the segment lifting mode.

[0044] The following specifically describes each step for entering the K-block transfer mode.

[0045] In step 401, a lifting instruction is sent to the support device to control the lifting of the two strut structures in the support device to support the K-block.

[0046] Figure 5 The following is a flowchart for controlling the support device in an embodiment of the present invention. In one embodiment, before sending the lifting instruction to the support device, it further includes:

[0047] Step 501: According to the control instruction, perform contour scanning on the currently grabbed object, and judge whether the currently grabbed object is a segment or a K-block based on the scanned contour information;

[0048] Sending the lifting instruction to the support device includes:

[0049] Step 502: When the grabbed object is a K-block, send a lifting instruction to the support device to lift the two strut structures.

[0050] Figure 6 The following is another flowchart for controlling the support device in an embodiment of the present invention. In one embodiment, before sending the lifting instruction to the support device, it further includes:

[0051] Step 601: According to the control instruction, perform point cloud detection on the preset K-block placement area to obtain the obstacle point cloud detection result of the preset K-block placement area;

[0052] Sending the lifting instruction to the support device includes:

[0053] Step 602: When the obstacle point cloud detection result indicates no obstacle, send a lifting instruction to the support device.

[0054] In a specific embodiment, according to the collected point cloud, the center coordinate position of the segment transport vehicle head is identified; the radar point cloud technology is used to detect whether there are obstacles in the preset K-block placement area; if there are no obstacles, the K-block transfer is performed. Figure 7 The following is a schematic diagram of the K-block and segment transfer process in an embodiment of the present invention. The K-block transfer and segment hoisting processes are as follows:

[0055] S1: The communication module of the control center is connected to the communication module of the transport vehicle to receive and send data and control instructions.

[0056] S2: The control center sends a lifting instruction to the support device.

[0057] S3: After the support device on the transport vehicle receives the lifting instruction, the control center controls the drive device to push the strut structure from the 0 position (the hidden state of the strut structure) to the lifted state (the manually set lifting height).Figure 8 Schematic diagram of the lifting support device supporting the K block in the embodiment of the present invention.

[0058] S4: After detecting that the ascent is in place through the proximity switch, send an ascent completion signal to the control center.

[0059] S5: The crane grabs the K block and lifts it to the set safe height.

[0060] S6: The control center controls the crane to move the K block onto the support device and complete the issuance of the segment. As Figure 2 shown, the process of segment issuance is as follows: When the K block moves onto the support device, the crane grabs the segment that was originally below the K block to complete the transportation of the segment.

[0061] S7: The control center hoists the segment below the K block to the position of the transport vehicle, and then grabs the K block on the support device by the crane and places it on the transport vehicle to be transported to the designated position.

[0062] In step 402, a grabbing instruction is issued to the crane to control the crane to move above the position of the K block and grab the K block; in step 403, a transportation instruction is issued to the transport vehicle to control the transport vehicle to transport the K block to the designated position.

[0063] In a specific embodiment, the automatic segment hoisting operation mode is started, and the radar collects the point cloud information of the operation area. When it is recognized that the segment to be grabbed is the K block, it is detected whether there are obstacles in the K block transfer area of the segment transport vehicle. If there are no obstacles, the target position of the K block transfer and placement area is calculated by identifying the three-dimensional coordinates of the transport vehicle. Then the automatic control center of segment hoisting completes the grabbing of the K block, sends a lifting instruction to the support device, and after the support device automatically completes the lifting action and sends a completion instruction to the automatic control center of segment hoisting, the automatic control center of segment hoisting controls the crane to complete the transfer of the K block, and then the control center automatically completes the hoisting work of all segments. After completing all hoisting operations, the control center sends a descent signal to the support device. After receiving the signal, the support device is controlled to retract, realizing the full automation of one ring of segments.

[0064] The embodiment of the present invention also provides a computer device, including a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, it implements the control method of the above trapezoidal K block transfer system.

[0065] The embodiment of the present invention also provides a computer-readable storage medium. The computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, it implements the control method of the above trapezoidal K block transfer system.

[0066] An embodiment of the present invention also provides a computer program product, which includes a computer program. When the computer program is executed by a processor, it implements the control method of the above trapezoidal K-block transfer system.
