[0024] When conducting pipeline transportation for empirical water supply and drainage, the staff first starts the hydraulic cylinder 6 through the controller, and the telescopic end of the hydraulic cylinder 6 pushes the workbench 2 to adjust the height, so as to facilitate subsequent transportation according to the installation height of the pipeline, and then extends the end of the water supply and drainage pipeline to be transported into the square through hole 2011 of a fixed plate 201, so that the lower surface of the outer wall of the pipeline is placed on the arc surface of the two first support plates 203, and the outer wall of the roller 5 is in contact with the outer wall of the pipeline, and then starts the forward and reverse motor 8 through the controller, and the output end of the forward and reverse motor 8 makes the connected drive assembly 3 work, and the two drive assemblies 3 work synchronously through the transmission chain, so that the vertical rod 2041 on the two fixed plates 201 moves downward, and the downward vertical rod 2041 drives the second support plate 204 to move, and the arc surface of the second support plate 204 contacts the upper surface of the outer wall of the pipeline, and at this time, the plurality of balls 205 on the first support plate 203 and the second support plate 204 are in contact with the outer wall of the pipeline; When the driving assembly 3 is working, the first driving member of the driving assembly 3 is driven to rotate through the meshing of the gears. After the second supporting plate 204 contacts with the pipe and completes the clamping, the connecting mechanism in the driving assembly 3 is energized through the controller, so that the two actuators of the driving assembly 3 are connected, and the rotational force can be transmitted to the rotating assembly 7. Under the action of the rotating assembly 7, the shaft 501 drives the roller 5 to rotate, and the friction force of the roller 5 cooperates with a number of balls 205 to transport the pipe. When the end of the pipe is transported to the square through hole 2011 of another fixed plate 201, the distance between the second supporting plate 204 of the square through hole 2011 and the first supporting plate 203 is the same as the distance between the second supporting plate 204 and the first supporting plate 203 in the square through hole 2011 that is initially inserted, and the end of the pipe can be directly inserted. The arrangement of the two fixed plates 201 can further support the longer pipe while ensuring the transportation effect. Therefore, the present application can adapt to pipelines of different lengths and complete transportation by changing the clamping and conveying forms, and the clamping and conveying effects can be achieved through one driving source, which is more energy-saving.

The first transmission sprocket 305 drives another first transmission sprocket 305 to rotate through the first transmission chain, so that the other vertical shaft 301 and the installed driving wheel 307 rotate accordingly. The two vertical shafts 301 rotate simultaneously and both drive the lead screw 303 to rotate through the magnetic coupler 302 at the bottom.

At this time, the first transmission shaft 402 and the second transmission shaft 407 are in a separated state. After the second support plate 204 contacts and clamps the pipeline, the electromagnet 4051 in the connection mechanism is started by the controller. The electromagnet 4051 is energized to generate magnetism to adsorb the iron plate 406. The magnetically adsorbed iron plate 406 moves upward and drives the telescopic end of the telescopic rod 404 to extend through the limiting slider 4061. During the extension process, the square plug rod 4041 contacts the bottom end of the first transmission shaft 402. Since the rotation speed of the forward and reverse motor 8 is relatively low, the rotation speed of the first transmission shaft 402 is also relatively low, which facilitates the square plug rod 4041 to be inserted into the square plug slot 4021, thereby completing the connection between the first transmission shaft 402 and the second transmission shaft 407. At this time, the second transmission shaft 407 rotates along with the first transmission shaft 402, and drives the installed first bevel gear 4071 to rotate.

[0031] The working principle of the present invention is: When conducting pipeline transportation for water supply and drainage, the staff first starts the hydraulic cylinder 6 through the controller. The telescopic end of the hydraulic cylinder 6 pushes the workbench 2 to adjust the height, so as to facilitate subsequent transportation according to the installation height of the pipeline. Then, the end of the water supply and drainage pipeline to be transported is extended into the square through hole 2011 of a fixed plate 201, so that the lower surface of the outer wall of the pipeline is placed on the arc surface of the two first support plates 203. At this time, the outer wall of the roller 5 contacts the outer wall of the pipeline, and then the forward and reverse motor 8 is started through the controller. The output end of the forward and reverse motor 8 drives the connected vertical shaft 301 to rotate. The vertical shaft 301 drives the first transmission sprocket 305 and the driving wheel 307 to rotate. The first transmission sprocket 305 drives the other through the first transmission chain. A first transmission sprocket 305 rotates, causing another vertical shaft 301 and the installed driving wheel 307 to rotate accordingly. The two vertical shafts 301 rotate simultaneously, and both drive the screw rod 303 to rotate through the magnetic coupler 302 at the bottom. Under the restriction of a limiting plate 2042 and a sliding rod 304, the limiting plate 2042 sleeved on the screw rod 303 moves vertically following the rotation of the screw rod 303, causing the vertical rods 2041 on the two fixed plates 201 to move downward. The vertical rods 2041 that move downward drive the second support plate 204 to move, and the arc surface of the second support plate 204 contacts the upper surface of the outer wall of the pipe. At this time, the plurality of balls 205 on the first support plate 203 and the second support plate 204 contact the outer wall of the pipe. The two driving wheels 307 drive the meshing driven wheels 4022 to rotate, and the driven wheels 4022 drive the first transmission shaft 402 to rotate. At this time, the first transmission shaft 402 and the second transmission shaft 407 are in a separated state. After the second support plate 204 contacts and clamps the pipeline, the electromagnet 4051 in the connection mechanism is started by the controller. The electromagnet 4051 is energized to generate magnetism to adsorb the iron plate 406. The magnetically adsorbed iron plate 406 moves upward and drives the telescopic end of the telescopic rod 404 to extend through the limiting slider 4061. During the extension process, the square plug rod 4041 contacts the bottom end of the first transmission shaft 402. Since the rotation speed of the forward and reverse motors 8 is relatively low, the rotation speed of the first transmission shaft 402 is also relatively low, which facilitates the square plug rod 4041 to be inserted into the square plug slot 4021, thereby completing the connection between the first transmission shaft 402 and the second transmission shaft 407. At this time, the second transmission shaft 407 rotates following the first transmission shaft 402, and drives the installed first bevel gear 4071 to rotate, and the first bevel gear 4071 drives the meshing second bevel gear 4081 to rotate, and the second bevel gear 4081 transmits the rotational force to another second bevel gear 4081 through the rotating shaft 408, and the third bevel gear 703 rotates following the second bevel gear 4081, and the third bevel gear 703 drives the penetrating horizontal shaft 704 to rotate, and the horizontal shaft 704 drives the installed second transmission sprocket 701 to rotate, and the second transmission sprocket 701 drives the second transmission sprocket 701 fixed on the shaft 501 to rotate through the second transmission chain 702, so that the shaft 501 rotates following the rotation of the horizontal shaft 704, and the rotation of the shaft 501 drives the roller 5 to rotate, and the friction force of the roller 5 cooperates with a number of balls 205 to enable the pipeline to be transported.
