Description

Technical Field

[0001] The invention relates to the technical field of water conservancy project construction, and in particular to a water conservancy construction pipeline burying construction device. Background Art

[0002] The essence of water conservancy projects is to scientifically manage and rationally utilize water resources through human intervention, and to solve the problem of uneven distribution of water resources in time and space. In inter-basin water transfer projects, pipeline laying is the key to achieving long-distance water transportation. During construction, ditches are first dug, and then qualified pipes are placed into the trenches using cranes, slides, etc., and welded or spliced ​​according to the material to ensure no leakage. Finally, plain soil or sand and gravel are symmetrically backfilled and compacted, and signs are buried to restore the site to form a water transmission channel.

[0003] Pipe splicing usually adopts a manual and mechanical collaborative operation mode, where the machine is responsible for the pipeline lifting operation and the manual labor is responsible for the pipeline splicing. During mechanical lifting, the pipeline shakes due to the loose lifting rope and the influence of wind. It is difficult for manual labor to accurately control the spatial position of the pipeline, which in turn affects the quality and efficiency of the splicing. Secondly, the operation mode in which the mechanical crane can only lift a single pipeline at a time fundamentally restricts the efficiency of pipeline laying and extends the construction period. In response to the above problems, the inventors proposed a water conservancy construction pipeline burying construction device to solve the above problems. Summary of the Invention

[0037] By adopting the above technical solution, the two groups of clamping frames 603 are brought into close proximity with each other to clamp both ends of the laid pipeline synchronously, thereby ensuring the stability of pipeline laying and transportation.

[0038] The loading limit assembly 4 includes two symmetrically distributed limit frames 401 and side panels 405. The two limit frames 401 are respectively slidably installed on both sides of the bottom end of the adjustment frame 2 through slide rails.

[0039] By adopting the above technical solution, the two limit frames 401 are made to move closer to or farther away from each other synchronously, thereby achieving precise positioning of the pipeline or rapid release of positioning.

[0040] A top frame 309 is fixedly installed on the side of the adjustment frame 2 close to the buried pipe positioning component 3, and a screw rod 310 is rotatably installed on the top frame 309. A screw ring 311 is provided on the threaded sleeve of the outer wall of the screw rod 310, and the screw ring 311 is fixedly installed in the middle of the top of the lifting frame 301. A servo motor 312 is fixedly installed on the side of the top of the adjustment frame 2 close to the screw rod 310, and the driving end of the servo motor 312 is connected to the screw rod 310 through a synchronous wheel transmission group.

[0041] By adopting the above technical solution, the screw rod 310 rotates through the wire ring 311 to drive the lifting frame 301 to slide vertically in the adjustment frame 2, and the position of the guide frame 304 is adjusted to adapt to ditches of different depths.

[0042] A lifting rod 305 is connected to the middle of the top of the positioning frame 302 through a spline, and a lifting block 306 is fixedly installed at the bottom of the lifting rod 305. Connecting rods 307 are rotatably provided at both ends of the lifting block 306, and the other ends of the connecting rods 307 are rotatably connected to the corresponding positioning clamping plates 303. An electric cylinder No. 1 308 is fixedly installed in the middle of the top of the positioning frame 302, and the driving end of the electric cylinder No. 1 308 is fixedly connected to the top of the lifting rod 305.

[0043] By adopting the above technical solution, the No. 1 electric cylinder 308 pushes the lifting block 306 to move stably up and down under the guidance of the lifting rod 305. The spline connection can improve the stability of the lifting rod 305 and prevent the lifting rod 305 from rotating and deviating.

[0044] Two sets of symmetrically distributed rolling balls are rotated on both sides of the inner wall of the guide frame 304 and the clamping frame 603, and each set of rolling balls has three equidistantly distributed balls for sliding on the outer wall of the pipe.

[0045] By adopting the above technical solution, the guide frame 304 slides close to the outer wall of the laid pipe, positioning the unspliced ​​pipe so that the pipe always maintains the same axial position. The unlaid pipe can slide radially in the clamping frame 603 to facilitate pipe splicing and installation.

[0046] A No. 4 electric cylinder 806 is fixedly installed in the middle of the top of the bottom plate 801 close to the frame 1, and the driving end of the No. 4 electric cylinder 806 is fixedly connected to the slide 805. A partition frame 807 is fixedly installed on the top of the loading rack 7 close to the frame 1, which cooperates with the unloading guide plate 802.

[0047] By adopting the above technical solution, the No. 4 electric cylinder 806 pushes the slide plate 805 to move under the guidance of the slide rail.

[0048] An arc-shaped plate 402 is fixedly mounted on the inner side of the limiting frame 401 by bolts. Two symmetrically distributed guide wheels 403 are fixedly mounted on the inner wall of the arc-shaped plate 402 . A baffle 404 is fixedly mounted on the top of the arc-shaped plate 402 near the side plate 405 .

[0049] By adopting the above technical solution, the arc-shaped plate 402 can slide closely against the outer wall of the pipeline through the guide wheel 403.

[0050] A guide inner frame 409 is rotatably mounted on the end of the arc plate 402, a flip plate 411 is slidably mounted on the outer wall of the guide inner frame 409, a sliding frame 410 is rotatably mounted on the other end of the flip plate 411, and the sliding frame 410 is slidably connected to the frame 1 through a slide rail.

[0051] By adopting the above technical solution, the sliding frame 410 slides in the flip plate 411, and the arc plate 402 drives the sliding frame 410 to move synchronously during the movement.

[0052] A feeding guide plate 808 is fixedly mounted on the feeding rack 7 by bolts for guiding pipeline transportation.

[0053] By adopting the above technical solution, the pipeline is transported in an orderly manner along a predetermined route under the action of the feeding guide plate 808.

[0054] Working principle: In actual application, first Figure 1 、 Figure 7 As shown, the pipes are pre-arranged on the loading rack 7, and an inclined slide is formed by the bottom plate 801 and the loading guide plate 808, and gravity is used to make the pipes roll naturally to the partition 807, as shown in FIG. Figure 13 As shown, the spacer 807 limits the position of the pipeline. At this time, the pipeline is directly above the blanking plate 803. Then the construction device is moved to the pre-dug ditch so that the ditch is located in the middle of the frame 1;

[0055] When cutting the pipe, Figure 8 、 Figure 10 As shown, the driving end of the No. 4 electric cylinder 806 is controlled to extend and push the slide plate 805 to move under the guidance of the slide rail. The inclined groove on the slide plate 805 and the vertical groove of the unloading guide plate 802 act together on the guide bolt 804. The inclined groove pushes the guide bolt 804 to move up along the vertical groove, driving the unloading plate 803 to rise vertically. The unloading plate 803 lifts the pipe at the bottom layer. At this time, the pipe at the rear is blocked by the unloading plate 803. Since the unloading plate 803 is tilted toward one side of the frame 1, when the pipe exceeds the height of the partition 807, it slides into the curved plate 402 along the flip plate 411 and the guide inner frame 409 under the action of the loading guide plate 808. At this time, the pipe is located on the guide wheels 403 inside the curved plates 402 on both sides. After the loading is closed, the No. 4 electric cylinder 806 is controlled to reset, and the subsequent pipes are naturally rolled and filled under the action of gravity;

[0056] Then, if Figure 6 As shown, the scissor-type lifting device 5 is controlled to drive the clamping frame 601 to descend to a specified height, so that the clamping frame 603 is aligned with both ends of the pipe, and the No. 3 electric cylinder 607 is controlled to be turned on. The driving end of the No. 3 electric cylinder 607 pulls the I-shaped lifting frame 604 to move vertically upward under the guidance of the two guide rods 606. The I-shaped lifting frame 604 drives the two adjacent clamping plates 602 and the clamping frame 603 to move closer to each other through the pull rod 605, so that the multiple groups of rolling balls fit the outer wall of the pipe to clamp and fix the pipe, as shown in FIG. Figure 5 As shown, after the pipe is clamped, the second electric cylinder 408 is controlled to start, and the driving end of the second electric cylinder 408 extends to push the guide outer frame 406 to descend vertically. The guide outer frame 406 pushes the two limit frames 401 away from each other and separates from the pipe through the push rod 407, and the contact limits the position of the pipe. During the movement of the limit frame 401, the guide inner frame 409, the flip plate 411 and the sliding frame 410 are driven by the arc plate 402 to slide synchronously under the guidance of the slide rail;

[0057] After the pipeline is released from the restriction, the scissor-type lifting device 5 drives the pipeline to continue to descend into the ditch, and then the driving end of the No. 3 electric cylinder 607 is controlled to reset to release the clamping of the pipeline. Then, the scissor-type lifting device 5 drives the clamping frame 601 to rise and reset. At the same time, the driving end of the No. 2 electric cylinder 408 is controlled to retract and drive the two limit frames 401 to reset, thereby completing the first pipeline placement operation;

[0058] During the subsequent pipe splicing and installation, the operator can manually adjust the position of the adjustment frame 2 through the handrail on one side of the loading limit assembly 4 so that the two guide frames 304 are approximately located in the center of the pipe. Figure 2 、 Figure 4 As shown, the driving end of the servo motor 312 is controlled to drive the screw rod 310 to rotate forward, and the screw rod 310 drives the lifting frame 301 and the positioning frame 302 to descend synchronously through the wire ring 311 so that the guide frame 304 corresponds to the position of the pipeline. Then, the driving end of the No. 1 electric cylinder 308 is controlled to extend, and the No. 1 electric cylinder 308 pushes the lifting block 306 to rise vertically synchronously through the lifting rod 305, driving the two positioning splints 303 and the guide frame 304 to approach each other, and the ball group on the inner wall of the guide frame 304 rolls in contact with the outer wall of the pipeline. When the guide frame 304 fits the outer wall of the laid pipeline, the adjustment frame 2 is slidably connected to the frame 1 through the slide rail, and can be automatically fine-tuned according to the position of the laid pipeline to ensure that the pipeline to be laid and the laid pipeline always maintain the same axis.

[0059] According to the same steps as above, the pipe to be connected is driven down to the same position as the laid pipe. Because the two pipes are on the same axis, when the pipes need to be connected, the operator only needs to apply external force to the pipe along its axis. At this time, relative rolling occurs between the outer wall of the pipe and the rolling ball, and the traditional sliding friction is converted into rolling friction, which significantly reduces the resistance during the movement of the pipe. At the same time, the guide frame 304 and the clamping frame 603 form radial constraints on the pipe, ensuring that the pipe maintains a straight motion trajectory during movement, thereby realizing fast and accurate connection of the pipe.

[0060] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
