Description

Technical Field

[0001] This application relates to the field of pipeline installation equipment, and in particular to a lifting and installation device and construction method for water supply and drainage pipelines. Background Technology

[0002] Water supply and drainage pipelines are responsible for the transportation of domestic water and the discharge of sewage. In addition, they can also be used for rainwater discharge and prevention of urban flooding. In order to avoid the pipelines affecting traffic, they are usually installed underground.

[0003] When installing water supply and drainage pipes, hoisting machinery is usually used for hoisting. Traditionally, the pipes are tied with ropes or strips of cloth, and then lifted and placed in the pipe pit by the hoisting machinery's arm. However, the pipes are usually placed on the ground or stacked with other pipes. When using ropes to tie the pipes, one end of the pipe needs to be lifted so that the rope can pass around the pipe for tying. Also, when the pipe is placed in the pipe pit, it is easy for the pipe to compress the rope, making it difficult to remove the rope, resulting in low overall construction efficiency. Summary of the Invention

[0004] To address the issue of complex rope binding and dismantling leading to low overall construction efficiency, this application provides a water supply and drainage pipeline hoisting and installation device and construction method.

[0005] On the one hand, the water supply and drainage pipeline hoisting and installation device provided in this application adopts the following technical solution:

[0006] A water supply and drainage pipeline hoisting and installation device includes hoisting machinery for lifting and moving the pipeline, a support frame mounted on the mechanical arm of the hoisting machinery, and ropes for binding the pipeline. It also includes:

[0007] The hook assembly is rotatably mounted on the support frame and is used to insert into and fix the pipe from both ends of the pipe.

[0008] A lasso assembly, rotatably mounted on the support frame, is used to support the rope and allow the pipe to pass through the rope;

[0009] A winding unit, mounted on the lasso assembly, is used to wind up or unwind the rope;

[0010] A disassembly unit, mounted on the lasso assembly, is used to keep the rope fixed to and disassembled from the lasso assembly;

[0011] The opening unit is provided on the lasso assembly and is used to open the wound rope and overlap it on the lasso assembly;

[0012] A slow release unit, mounted on the support frame, is used to support the pipe and create a gap between the pipe and the bottom wall of the pipe pit.

[0013] By adopting the above technical solution, when hoisting pipelines, the hoisting machinery first drives the robotic arm to move, and the robotic arm moves the support frame to above the pipeline. Then, the hooking assembly extends from both ends of the pipeline and hooks it. The robotic arm then lifts the pipeline, and the sling assembly rotates and is fitted onto the pipeline. The winding unit then winds up the rope, which binds and secures the pipeline. The support frame is placed in the pipeline pit, and the rope is then removed by the dismantling unit. The winding unit pulls the rope through the gap formed by the slow release unit support, causing the rope to detach from the pipeline. The support frame is then raised, and the opening unit opens the rope, allowing it to bind and secure the next pipeline. The pipeline lifting, binding, and rope removal are completed mechanically, improving the convenience of binding and dismantling the pipeline and increasing the hoisting efficiency of water supply and drainage pipelines.

[0014] In one specific implementation, the hook assembly includes hooks respectively disposed at both ends of the support frame, one end of the hook being rotatably disposed with the support frame, and the other end of the hook abutting against the inner wall of the pipe, and the support frame is provided with a first driving unit for driving the hooks to rotate.

[0015] By adopting the above technical solution, when lifting the pipeline, the first drive unit drives the hooks on both sides of the support frame to insert into the pipeline from both ends, thereby achieving the connection of the pipeline and enabling the robotic arm to lift the pipeline.

[0016] In one specific implementation, the lasso assembly includes two mounting brackets through which the pipe passes, the mounting brackets being rotatably disposed relative to the support frame along the axial direction of the pipe, the mounting brackets having an outlet for the pipe to be removed, and the support frame having a second drive unit for driving the mounting brackets to rotate.

[0017] By adopting the above technical solution, the second drive unit drives the mounting bracket to rotate and fit onto the pipe from both ends, and then the pipe can be detached from the mounting bracket from the outlet.

[0018] In one specific implementation, the winding unit includes a winding drum, a guide block, and a release element. The winding drum is rotatably mounted to the mounting frame. One end of the rope away from the disassembly unit is disposed on the winding drum. The guide block supports the rope to form a binding space for the insertion of the pipe. The release element is used to guide the rope to detach from the guide block.

[0019] By adopting the above technical solution, when the mounting frame is installed on the pipeline, the guide rope of the detachment component separates from the guide block, and then drives the winding drum to rotate, and the winding drum rope is wound up and tightened, thereby binding and fixing the pipeline, thus improving the stability and safety of the pipeline during the hoisting process.

[0020] In one specific implementation, the guide block is provided with a slot for inserting the rope, and the side wall of the slot is provided with a release port for the rope to slide out;

[0021] The detachment component includes a sliding plate and a second electric cylinder. The sliding plate is used to block the release port. The sliding plate is slidably disposed with the guide block. The second electric cylinder is used to drive the sliding plate to slide. The bottom wall of the slot is provided with a guide surface for guiding the rope to slide toward the release port.

[0022] By adopting the above technical solution, when the rope detaches from the guide block, the second electric cylinder is first moved to drive the sliding plate away from the release port, so that the release port opens. Then, the winding drum is rotated to wind up the rope. The stretched rope slides along the guide surface toward the release port, so that it slides out of the release port and detaches from the guide block, thereby realizing the binding and fixing of the rope to the pipeline.

[0023] In one specific implementation, the disassembly unit includes a locking block, a locking plate, and a first electric cylinder. The locking block is fixedly disposed at the end of the rope away from the winding drum. The locking plate includes two pressing plates for pressing the locking block. One pressing plate is disposed on the support rod, and the other pressing plate is disposed on the first electric cylinder. The two pressing plates are provided with a locking groove for the locking block to be inserted. The two pressing plates press the locking block into the locking groove to fix the locking block.

[0024] By adopting the above technical solution, when disassembling the rope, the first electric cylinder drives one squeezing plate away from the other squeezing plate, so that the squeezing plate releases the squeezing of the locking block and the locking block can be pulled out from the locking groove. Under the winding of the rope by the winding drum, the locking block is pulled out from the locking groove, thereby realizing the disassembly of the rope.

[0025] In one specific implementation, the mounting bracket is provided with a guide groove for the sliding of the locking block, the guide groove is connected to the locking groove, and the mounting bracket is provided with a linear drive unit, which pushes the locking block into the locking groove through a push plate.

[0026] By adopting the above technical solution, when the winding drum winds up the rope, the winding drum pulls the rope so that the locking block is inserted into the guide groove. At this time, the linear drive unit pushes the locking block to slide towards the locking plate, and then the first electric cylinder drives the pressing plate to fix the locking block, thereby realizing the re-fixation of the locking block.

[0027] In one specific implementation, the opening unit includes a rotating motor and a drive screw. The drive screw is rotatably arranged along the length of the mounting frame. The rotating motor is used to drive the drive screw to rotate. The drive screw passes through the guide block and is threadedly connected to the guide block. The guide block passes through the guide groove, causing the guide block to drive the rope to open.

[0028] By adopting the above technical solution, when the clamping block is fixed by the clamping plate again, the rotating motor drives the drive screw to rotate, and the drive screw drives the guide block to push the rope out of the guide groove, and pushes the rope to open on the mounting frame, so as to re-form the rope loop for pipe insertion, thereby realizing the binding and fixing of the pipe.

[0029] In one specific implementation, the slow release unit includes a fixed plate and a second hydraulic cylinder. The fixed plate is rotatably mounted on the support frame along the width direction of the pipe, and the second hydraulic cylinder is mounted on the support frame. The second hydraulic cylinder is used to push the fixed plate to compress and support the pipe.

[0030] By adopting the above technical solution, when the rope is detached from the pipe, the second hydraulic cylinder extends and squeezes the fixing plate to squeeze and support the pipe. This ensures that when the rope is detached from the pipe, there is a gap between the pipe and the bottom wall of the pipe pit, which allows the rope to pass through, making it easier for the winding drum to wind up the rope.

[0031] On the other hand, this application also provides a method for hoisting and installing water supply and drainage pipelines, using the following technical solution:

[0032] A method for hoisting and installing water supply and drainage pipelines includes the following steps: S1, first fix the pipeline using the hook assembly, and then lift the pipeline using the robotic arm;

[0033] S2. Rotate the lasso assembly to surround the pipe, and then use the winding unit to tie the rope to the pipe;

[0034] S3. The robotic arm places the pipe into the pipe pit, the disassembly unit disassembles the rope, the slow release unit supports the pipe, and the rope detaches from the pipe through the gap;

[0035] S4. The opening unit opens the wound rope to re-lift the pipe.

[0036] By adopting the above technical solution

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. When hoisting pipelines, the hoisting machinery first drives the robotic arm to move, which in turn moves the support frame above the pipeline. Then, the hooking assembly extends from both ends of the pipeline and hooks it. The robotic arm then lifts the pipeline. The sling assembly rotates and is fitted onto the pipeline. The winding unit then winds up the rope, which is used to secure the pipeline. The support frame is placed in the pipeline pit, and the rope is then removed using the dismantling unit. The winding unit pulls the rope through the gap formed by the slow release unit support, causing the rope to detach from the pipeline. The support frame is then raised, and the opening unit opens the rope, allowing it to secure the next pipeline. This mechanical method completes the pipeline lifting, binding, and rope removal, improving the convenience of binding and dismantling the pipeline and increasing the hoisting efficiency of water supply and drainage pipelines.

[0039] 2. When the mounting bracket is placed on the pipeline, the guide rope of the detachment component disengages from the guide block, and then the winding drum is driven to rotate, and the winding drum rope is wound up and tightened, thereby binding and fixing the pipeline, thus improving the stability and safety of the pipeline during the hoisting process.

[0047] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0048] On the one hand, this application discloses a water supply and drainage pipeline hoisting and installation device.

[0049] Reference Figure 1 , Figure 2 A water supply and drainage pipeline hoisting and installation device includes a hoisting machine 1, a mechanical arm 11 on the hoisting machine 1, a support frame 2 on the mechanical arm 11, the mechanical arm 11 being able to drive the support frame 2 to move spatially, and a hook assembly 21 on the support frame 2. In this embodiment, the hook assembly 21 includes two hooks 211, which are respectively located at both ends of the support frame 2 and are rotatably configured with the support frame 2. The support frame 2 is provided with a first drive unit 212 for driving the two hooks 211 to be inserted into and abutted from both ends of the pipeline. The support frame 2 is provided with a lasso assembly 22, which includes two mounting frames 221, which are rotatably configured with the support frame 2. The mounting frames 221 are located at a distance from the support frame 2. An outlet for the pipe to slide out is provided at one end of the support frame 2. The support frame 2 is provided with a second drive unit 222 for driving the installation frame 221 to rotate. Each installation frame 221 is provided with a rope 3 for binding the pipe, a winding unit 4, an opening unit 5, and a disassembly unit 6. The winding unit 4 is used to wind up or unwind the rope 3. The opening unit 5 is used to open the wound rope 3 so that the opened rope 3 can surround the pipe. The rope 3 is detachably connected to the installation frame 221 through the disassembly unit 6. The support frame 2 is provided with a slow release unit 7. When the rope 3 is detached from the installation frame 221, the slow release unit 7 can support the pipe and make a gap between the pipe and the bottom wall of the pipe pit for the rope 3 to pass through.

[0050] When hoisting water supply and drainage pipelines, the operator drives the hoisting machine 1 to move the support frame 2 above the pipeline via the robotic arm 11. Then, the first drive unit 212 drives two hooks 211 to insert into the pipeline from both ends and press against the inner wall of the pipeline to fix it in place. The robotic arm 11 is then driven to lift the pipeline. The second drive unit 222 then drives two mounting brackets 221 to slip onto the pipeline from both ends. At this time, the rope 3 is slipped onto the pipeline along with the mounting brackets 221. The winding unit 4 then winds up the rope 3. The rope 3 is used to bind the pipe, and then the hook 211 is pulled out of the pipe. At this time, the pipe is fixed by binding the rope 3. Then, the robotic arm 11 is operated to put the pipe into the pipe pit. Then, the disassembly unit 6 is used to separate one end of the rope 3 from the mounting frame 221. The release unit 7 supports the pipe slowly, and then the rope 3 is pulled out from the gap to complete the hoisting of the pipe. At the same time, the lifting, binding and rope pulling can be completed mechanically, which improves the convenience of binding and disassembling the pipe with the rope 3 and improves the hoisting efficiency of water supply and drainage pipes.

[0051] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the first drive unit 212 includes two first hydraulic cylinders 2121. In other embodiments, they can also be cylinders. The first hydraulic cylinders 2121 correspond one-to-one with the hooks 211. Each hook 211 is provided with a drive part 213. The drive part 213 is provided with a guide groove 214. The extension line of the guide groove 214 passes through the rotation axis of the hook 211. A guide block 215 rotates on the first hydraulic cylinder 2121 for sliding in the guide groove 214. The first hydraulic cylinder 2121 can drive the drive part 213 to rotate around the axis by an angle greater than 90 degrees.

[0052] When the support frame 2 moves above the pipe, the first hydraulic cylinder 2121 extends. The piston rod of the first hydraulic cylinder 2121 drives the drive unit 213 to rotate around the axis through the guide block 215. The drive unit 213 drives the hook 211 to rotate, so that one end of the hook 211 is inserted into the pipe. The hook 211 presses against the inner wall of the pipe, so that the robotic arm 11 can lift the pipe. When the mounting frame 221 is fitted onto the pipe, the first hydraulic cylinder 2121 retracts and drives the hook 211 to be pulled out of the pipe, so that the pipe is fixed by the rope 3, effectively avoiding the impact of the hook 211 on the pipe installation.

[0053] Reference Figure 2 , Figure 4The second drive unit 222 includes a drive motor 2221 with a self-locking function. The drive motor 2221 corresponds one-to-one with the mounting frame 221. The output shaft of the drive motor 2221 is coaxially and fixedly connected to the rotation shaft of the mounting frame 221. The winding unit 4 includes a winding drum 41, a guide block 42, and a release component 43. The winding drum 41 is coaxially rotatably mounted on the mounting frame 221. The mounting frame 221 is equipped with a motor that drives the winding drum 41 to rotate. In this embodiment, there are two guide blocks 42. Each guide block 61 is provided with a slot 431 for inserting the rope 3. The side wall of the slot 431 is provided with a release port 432 for the rope 3 to slide out. The bottom wall of 1 is provided with a guide surface 433, which is inclined towards the release port 432 so that the rope 3 can slide towards the release port 432 when it is tightened. The detachment part 43 is set on the guide block 42 and corresponds to the guide block 42 one by one. The detachment part 43 includes a sliding plate 434 and a second electric cylinder 435. The sliding plate 434 is slidably set with the guide block 42. The output shaft of the second electric cylinder 435 is fixedly connected to the sliding plate 434. The second electric cylinder 435 drives the sliding plate 434 to slide to the release port 432 and block the release port 432. The rope 3 passes through the slot 431 on each guide block 42 in sequence so that the rope 3 can surround the pipe.

[0054] Reference Figure 2 , Figure 5 The disassembly unit 6 includes a locking block 61, a locking plate 62, and a first electric cylinder 63. One end of the rope 3 is fixedly connected to the winding drum 41, and the other end of the rope 3 is fixedly connected to the locking block 61. The locking block 61 is cast from two upper and lower cylinders and a central disc. The locking plate 62 is composed of two extrusion plates 621, one of which is fixedly connected to the mounting bracket 221, and the other is fixedly connected to the output shaft of the first electric cylinder 63. Both extrusion plates 621 are provided with grooves, and the grooves on the two extrusion plates 621 form a locking groove 64 for the cylinder of the locking block 61 to be inserted.

[0055] Reference Figure 2 , Figure 4 and Figure 5The opening unit 5 includes a rotating motor 51 and a drive screw 52. Each mounting bracket 221 has two rotating motors 51, and each drive screw 52 corresponds to one of the rotating motors 51. The output shaft of the rotating motor 51 is coaxially fixed with the drive screw 52. Each drive screw 52 corresponds to one guide block 42. Each drive screw 52 is arranged along the length of the long rods on both sides of the mounting bracket 221 and is rotatably mounted with the mounting bracket 221. The drive screw 52 passes through the guide block 42 and is threadedly connected to it. The mounting bracket 221 is provided with a support rod 53, and the support rod 53 is provided with a guide groove 54. The guide groove 54 passes through the opposite sidewall of the support rod 53, guiding... The sidewall of the groove 54 extends to the side near the clamping plate 62. The drive screw 52 passes through the guide groove 54. When the winding drum 41 winds the rope 3, the rope 3 pulls the clamping block 61 into the guide groove 54. The mounting bracket 221 is provided with a linear drive unit 55 for pushing the clamping block 61 onto the clamping plate 62. In this embodiment, the linear drive unit 55 includes a lead screw. In other embodiments, it can also be a hydraulic cylinder. The nut of the lead screw is provided with a push plate 56 for pushing the clamping block 61. When the winding drum 41 winds the rope 3 to tighten the pipe, the drive screw 52 drives the guide block 42 to slide above the guide groove 54. The guide block 42 is still inserted into the guide groove 54 so that the clamping groove 431 is aligned with the guide groove 54.

[0056] Reference Figure 1 , Figure 2 and Figure 6 The slow release unit 7 includes a fixed plate 71 and a second hydraulic cylinder 72. The fixed plates 71 are both arranged on both sides of the support frame 2. The fixed plates 71 are rotatably arranged on the support frame 2 along the radial direction of the pipeline. The second hydraulic cylinder 72 corresponds to the fixed plate 71 and is fixedly arranged on the support frame 2. The output shaft end of the second hydraulic cylinder 72 is rotatably provided with a sliding block 73. The fixed plate 71 is provided with a sliding groove 74 for the sliding block 73 to slide. The sliding groove 74 is arranged along the length direction of the fixed plate 71.

[0057] After the robotic arm 11 lifts the pipe using the hook 211, the drive motor 2221 drives the mounting bracket 221 to rotate. The mounting bracket 221 is then fitted onto the pipe from both ends. The second electric cylinder 435 then drives the sliding plate 434 to slide, causing the sliding plate 434 to disengage from the release port 432. The release port 432 opens, and the winding drum 41 is activated. The winding drum 41 tightens the rope 3, causing the rope 3 to disengage from the guide block 42 under the pull of the winding drum 41. Then, as the winding drum 41 winds up, the rope 3... The pipe is tightly bound by rope 3, and then the second hydraulic cylinder 72 extends and pushes the fixing plate 71 to squeeze the pipe, thereby squeezing and fixing the pipe, effectively preventing the pipe from shaking when the robotic arm 11 is hoisting the pipe, and improving the safety of the robotic arm 11 in hoisting the pipe; when the rope 3 binds the pipe tightly, the first hydraulic cylinder 2121 retracts and drives the hook 211 to be pulled out from the pipe. The pulled-out hook 211 flips upward, effectively preventing the hook 211 from affecting the pipe hoisting and docking.

[0058] When the robotic arm 11 hoists the pipe into the pipe pit, the first electric cylinder 63 drives the extrusion plate 621 to disengage from the other extrusion plate 621, releasing the clamping plate 62 from restricting the clamping block 61. At this time, the pipe remains stationary under the clamping of the fixed plate 71. Then, under the pull of the winding drum 41, the rope 3 passes through the pipe, causing the rope 3 to disengage from the pipe. The winding drum 41 pulls the rope 3 to wind up and pulls the clamping block 61 to insert into the guide groove 54. Then, the second hydraulic cylinder 72 retracts, and the fixed plates 71 on both sides of the support frame 2 gradually open. The pipe gradually slides down on the fixed plate 71, thereby shortening the distance between the pipe and the bottom wall of the pipe pit, effectively preventing the pipe from falling and breaking.

[0059] When rope 3 detaches from guide block 42, motor 51 drives drive screw 52 to rotate. Drive screw 52 drives guide block 42 to slide towards support rod 53 and through guide groove 54 to above guide groove 54. The slot 431 end of guide block 42 is inserted into guide groove 54. When take-up drum 41 pulls block 61 into guide groove 54, screw pushes block 61 towards plate 62 via push plate 56. Push plate 56 pushes block 61 into the locking position. At slot 64, the first electric cylinder 63 pushes the extrusion plate 621 close to another extrusion plate 621. The two extrusion plates 621 fix the locking block 61 in the locking slot 64, thus completing the fixing of the locking block 61. Then, the rotating motor 51 drives the drive screw 52 to rotate, and the drive screw 52 drives the guide block 42 to slide. At this time, the rope 3 is inserted into the locking slot 431 and opens under the push of the guide block 42, realizing the re-binding and fixing of the pipe, so that the rope 3 can fix the pipe multiple times.

[0060] The implementation principle of the water supply and drainage pipeline hoisting and installation device in this application embodiment is as follows: When hoisting the pipeline, the hoisting machine 1 first drives the mechanical arm 11 to move, and the mechanical arm 11 drives the support frame 2 to move above the pipeline. Then, the hook group 21 extends from both ends of the pipeline and hooks the pipeline. Then, the mechanical arm 11 drives the pipeline to be lifted. Then, the lasso group 22 rotates and is sleeved on the pipeline. Then, the winding unit 4 winds up the rope 3, and the rope 3 binds and fixes the pipeline. The support frame 2 is placed in the pipeline pit. Then, the disassembly unit 6 removes the rope 3. The winding unit 4 pulls the rope 3 through the gap formed by the slow release unit 7, so that the rope 3 is separated from the pipeline. Then, the support frame 2 is lifted, and the opening unit 5 opens the rope 3, so that the rope 3 can bind and fix the next pipeline. The pipeline lifting, binding and rope pulling are completed mechanically, which improves the convenience of binding and disassembling the pipeline with the rope 3 and improves the hoisting efficiency of water supply and drainage pipelines.

[0061] On the other hand, this application also provides a method for hoisting and constructing water supply and drainage pipelines.

[0062] A method for hoisting and installing water supply and drainage pipelines includes the following steps: S1, first fix the pipeline by hooking group 21, and then lift the pipeline by mechanical arm 11;

[0063] S2. Rotate the lasso assembly 22 to surround the pipe, and then use the winding unit 4 to tie the rope 3 to the pipe;

[0064] S3, the robotic arm 11 places the pipe into the pipe pit, disassembles the rope 3 through the disassembly unit 6, and slowly releases the pipe support through the release unit 7. The rope 3 is then separated from the pipe through the gap.

[0065] S4. The opening unit 5 opens the wound rope 3 to re-lift the pipeline.

[0066] In step S1, the height at which the robotic arm 11 lifts the pipe from the ground should be greater than the difference between the length of the support frame 2 and the pipe diameter, but less than the length of the pipe diameter.

[0067] In step S2, the two mounting brackets 221 should be rotated to the vertical direction. When the rope 3 is binding the pipe, the pipe should be in contact with the support bracket 2. Then the drive screw 52 drives the guide block 42 to move up onto the support rod 53.

[0068] In step S3, a distance of 200mm-300mm should be set between the support frame 2 and the side wall of the pipe pit. Then, the first electric cylinder 63 drives the pressing plate 621 to slide and release the restriction on the clamping block 61. Then, the winding drum 41 winds up the rope 3. Then, the second hydraulic cylinder 72 drives the fixing plate 71 to rotate. The two fixing plates 71 gradually move away from each other and open up. The pipe slowly falls along the fixing plate 71.

[0069] In step S4, when the robotic arm 11 lifts the support frame 2, the mounting frame 221 reverses upwards, and at the same time, the rotating motor 51 drives the drive screw 52 to move the guide block 42, which in turn pushes the telescopic opening open.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
