[0034] like Figures 1 to 4 As shown, a transverse movement device for pipelines of a sea pipe laying operation line is arranged between an input device and an output device, and the transverse movement device includes: a rolling table 6, which is provided with a plurality of parallel ones, for supporting pipelines and providing a plane for sliding of the plurality of pipelines; a plurality of slide rails 3, which are provided with a plurality of parallel ones and fixedly arranged one by one on one side of the rolling table 6; a pushing device, which is arranged on the slide rail 3, for pushing the plurality of pipelines to roll and transversely move on the rolling table 6; a limiting device, which is arranged on the slide rail 3, for limiting the spacing of the plurality of pipelines one by one; and the input device is used to transport the pipelines one by one to one end of the rolling table 6, and the output device transports the pipelines on the rolling table 6 out one by one.

[0035] The working principle of the present invention is:

[0036] First, the pipe is transported to the right end of the rolling platform 6 by an input device (which can be a crane combined with manual labor). There are at least two rolling platforms 6 to achieve the purpose of stably supporting the pipe. Then, the pipes are pushed to roll one by one by a pushing device until each pipe reaches the specified position (i.e. Figure 1 The position of the dotted pipe in the middle), and then the limiting device limits the pipes at each specified position to prevent collision between the pipes. Then the limiting device releases the restriction, and then the pushing device pushes the pipe to move horizontally as a whole until the pipes at each position roll to the position of the previous pipe, so as to carry out horizontal transportation one by one.

[0037] In the present invention, the end dead stopper 1 is fixedly provided at one end of the slide rail 3 close to the input device, so as to prevent the input device from rolling in the opposite direction and falling off the slide rail 3 when transporting the pipeline to the rolling platform 6 .

[0038] The present invention provides a preferred embodiment of the pushing device and the limiting device:

[0039] The pushing device includes a plurality of lever seats 4 slidably mounted in the slide rail 3, a lever 19 is rotatably mounted on the lever seat 4, a lever wheel 12 is rotatably mounted on the top end of the lever 19, one side of the lever 19 is connected to the side of the lever seat 4 close to the input device through a reset spring, the reset spring is used to make the top end of the lever 19 only rotate in the direction close to the output device under the pressure of the pipeline when the pipeline passes, and reset after the pipeline passes; a plurality of pushing cylinder supports 26 are installed at the bottom end of the slide rail 3, a pushing cylinder 27 is fixedly mounted on the pushing cylinder support 26 in the middle position, the bottom ends of the plurality of lever seats 4 are fixed by a push rod 21 to form a whole, and the pushing cylinder 27 is used to push the whole to reciprocate. The limit device includes a plurality of limit blocks 20, the bottom end of each limit block 20 is hinged to the slide rail 3 through a limit block connecting rod 24, and a limit cylinder support 5 is fixedly installed on the pushing cylinder support 26 close to the input device, the limit cylinder support 5 is hinged to one end of the limit cylinder 17, and the limit block connecting rod 24 on the limit block 20 closest to the input device extends to the bottom end and is hinged with the other end of the limit cylinder 17. When the limit cylinder 17 contracts, the limit cylinder 17 drives the limit block 20 to rotate toward the side close to the output device through the limit block connecting rod 24, and the adjacent limit blocks 20 are fixedly connected as a whole through the limit block pull rod 22 for linkage, the limit block 20 closest to the output device is connected to the slide rail 3 through the limit block pull rod tension spring 25, and each limit block connecting rod 24 is connected to the slide rail 3 through the limit block connecting rod tension spring 23. A limit block lifting travel switch 18 is provided on the slide rail 3 at a position between the input device and the limit block 20 closest to the input device.

[0040] refer to Figure 5First, the pipeline is transported to the right end of the rolling table 6 through the input device (which can be a crane in combination with manual labor), and the right side of the pipeline abuts against the end dead stop block 1 (from the right to the left, every two limit blocks 20 are divided into a group, that is, the middle position of each group of limit blocks 20), and then the push cylinder 27 is manually started to push the output end of the cylinder 27 to move to the left, and the output end of the cylinder 27 drives the push rod 21 fixedly connected to it to move to the left, and the push rod 21 will drive all the lever seats 4 to slide to the left, so that all the levers 19 are pushed to move the pipeline to the left. Before the pushing action, the limit cylinder 17 is manually controlled to shrink, and the limit cylinder 17 will drive the rightmost limit block connecting rod 24 to rotate, and the rightmost limit block The left rotation of the connecting rod 24 will drive the rightmost limit block 20 to return to the slide rail 3. At this time, the rightmost limit block 20 rotates and transmits the rotation to all the limit blocks 20 through the limit block pull rod 22, so that all the limit blocks 20 are completely retracted. The lever 19 moves the pipeline to the left until the pipeline presses the limit block lifting travel switch 18. When the pipeline completely presses the limit block lifting travel switch 18, the limit block lifting travel switch 18 controls the limit cylinder 17 to recover, and then controls the limit block 20 to extend. During the control of the limit block lifting travel switch 18 and the extension of the limit block 20, the pipeline enters the first group of limit blocks 20 due to inertia. The top of each group of limit blocks 20 is provided with a slope that can be adjusted The pipeline is located in the middle of the first group of limit blocks 20, and then the pipeline is braked. At this time, the limit cylinder 17 is manually controlled to shrink, and the limit cylinder 17 will drive the rightmost limit block connecting rod 24 to rotate. The left rotation of the rightmost limit block connecting rod 24 will drive the rightmost limit block 20 to return to the slide rail 3. At this time, the rightmost limit block 20 rotates and transmits the rotation to all the limit blocks 20 through the limit block pull rod 22, which can make all the limit blocks 20 return to the slide rail 3. At the same time, the input device transports the new pipeline to the position of the end dead block 1, and then the push cylinder 27 is manually started again to push the output end of the cylinder 27 to move to the left, and the output end of the cylinder 27 drives the fixed connection The connected push rod 21 moves to the left, and the push rod 21 will drive all the lever seats 4 to slide to the left. The movement of all the levers 19 will make the new pipe at the position of the end dead stop block 1 move to the middle of the first group of limit blocks 20, and the pipe in the first group of limit blocks 20 will move to the middle of the second group of limit blocks 20 at the same time. In the process of moving the new pipe, since the two pipes are moved away synchronously, the new pipe can press the limit block to raise the travel switch 18, so that when the new pipe reaches the corresponding position of the first group of limit blocks 20, all the limit blocks 20 extend synchronously to stop the new pipe. By analogy, when the pipe enters the leftmost group of limit blocks 20, the lever 19 pushes the pipe into the output device, thereby forming an assembly line operation.

[0041] The present invention also provides a preferred solution of the input device, the input device includes a lifting drive device 2, the lifting drive device 2 is arranged on one side of the corresponding end of the slide rail 3, a plurality of lifting cylinders 7 are fixedly mounted on the lifting drive device 2, an input end longitudinal driving roller group 14 is mounted on the top of the plurality of lifting cylinders 7, one end of the input end longitudinal driving roller group 14 is provided with an input end longitudinal driving motor 8 for driving the same. It also includes an intermediate conduction device, the intermediate conduction device is arranged between adjacent slide rails 3, the intermediate conduction device includes a base 1, another input end longitudinal driving roller group 14 is mounted on the base 1 so as to be longitudinally reciprocating and translating through an input end lifting arm 15 and an input end lifting parallel connecting rod 16, the base 1 is also provided with another input end longitudinal driving motor 8 for driving the same, one end of the input end lifting cylinder 11 is also hinged on the base, the other end of the input end lifting cylinder 11 is hinged with the input end lifting arm 15.

[0042] Since the pipeline is vertically long, it can be vertically transported by using the common input-end longitudinal drive roller group 14. The special thing about the present invention is that the pipeline on the input-end longitudinal drive roller group 14 can be lifted to a height slightly higher than or flush with the slide rail 3 through the lifting cylinder 7, and the pipe can be gradually pushed onto the slide rail 3 through the input-end longitudinal drive roller group 14. Since the interval between the slide rails 3 may be large, one end of the pipeline will fall between the slide rails 3. Therefore, the slide rails 3 are also vertically transported by the corresponding end of the pipeline between the slide rails 3 through an intermediate conduction device. The specific roller drive and installation method can be the same as the prior art. The present invention only needs to be able to raise and lower the conveying surface.

[0043] In the present invention, the output device includes a base 2 and a transverse centering cylinder 9 at the output end. The transverse centering cylinder 9 at the output end is used to adjust the transverse position of the base 2. An output end longitudinal drive roller group 13 is rotatably installed on the base. An output end longitudinal drive motor 10 is installed on one side of the output end longitudinal drive roller group 13. The output end longitudinal drive motor 10 is used to drive the output end longitudinal drive roller group 13 to rotate.

[0044] The leftmost lever 19 can move the leftmost pipe to the longitudinal drive roller group 13 at the output end. The specific roller drive and installation method can also adopt the same method as the prior art. The horizontal centering cylinder 9 at the output end can be adjusted to return the transported pipe to the vertical conveying device.

[0045] It is worth noting that the specific location and manner of the pushing device and the limiting device are not limited, as long as the movements of the two do not interfere with each other. In this embodiment, the pushing device and the limiting device are both arranged in the slide rail 3. Figure 4Only the installation position of the pushing device in the slide rail 3 can be seen, and the limiting device cannot be seen intuitively. It is only necessary to set the limit block connecting rod 24 and other structures in the gap between the lever seat 4 and the inner cavity of the slide rail 3. The lever 19 can rotate to the left when resetting to avoid the limit block 20.
