Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a water conservancy pipeline lifting and transportation device. Background Art

[0002] Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals. The goal is to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging, and regulate and distribute water to meet the needs of people's lives and production for water resources. Pipeline laying is an important infrastructure in water conservancy construction. Pipes in water conservancy construction are made of a variety of materials, such as cement pipes, cast iron pipes, and pipes made of polymer materials.

[0003] Cement pipes are often needed in water conservancy projects to build water conservancy facilities. Their regular length is generally two to three meters. During the lifting process of cement pipes, ropes are generally used to tie the cement pipes and lift them through hooks. The binding ropes need to be manually removed before and after the pipes are lifted. The operation is cumbersome and affects work efficiency. At the same time, lifting through ropes causes the cement pipes to shake during lifting and transportation, making the pipes unstable during lifting and there is a risk of collision damage or falling, so there are certain limitations.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] Example 1: Reference Figure 1-8 A hydraulic pipeline lifting and transportation device comprises a bracket 1 provided with a movable slideway 101, and further comprises:

[0038] Winch 2, the winch 2 is fixed on the bracket 1, and the winch 2 is connected to a sliding block 201 sliding in the moving slideway 101 through a traction rope;

[0039] A hydraulic rod 3, the hydraulic rod 3 is fixedly connected to the sliding block 201, the bottom of the hydraulic rod 3 is connected to a mounting plate 301, and both sides of the mounting plate 301 are provided with a lifting mechanism for lifting the pipeline body 6;

[0040] The lifting mechanism includes a connecting seat 4 fixedly connected to the mounting plate 301 , and a self-clamping component and an anti-falling component matched with the self-clamping component are arranged on the connecting seat 4 .

[0041] Specifically, the staff uses the traction rope and the sliding block 201 through the winch 2 to drive the hydraulic rod 3 to move, so that the hydraulic rod 3 drives the lifting mechanism to move to the upper side of the pipe body 6 to be lifted, and then controls the hydraulic rod 3 to work, the hydraulic rod 3 drives the lifting mechanism to move downward, the lifting mechanism abuts against the pipe body 6, and the self-clamping component works automatically, and can directly clamp and lift the pipe body 6 without the need for the staff to tediously bind and hook, thereby reducing the binding time before and after lifting and transportation, and improving the efficiency of pipeline lifting and lifting. When the self-clamping component is working, the self-clamping component drives the release and falling component to work automatically, so as to realize automatic limiting of the side of the pipe body 6, effectively preventing the pipe body 6 from falling off from the side of the device, avoiding the risk of falling during the pipeline lifting and transportation, and improving the safety of lifting and transportation. At the same time, the present application uses the hydraulic rod 3 to lift the pipe body 6, and rigidly connects the pipe body 6, thereby avoiding the use of ropes to cause the pipeline to shake during lifting and transportation, and improving the stability of the pipeline body 6 lifting and transportation.

[0042] Example 2: Reference Figure 1-11 , a hydraulic pipeline lifting and transportation device, based on Example 1, further, the self-clamping component includes a moving rod 5 slidably connected to the connecting seat 4, the top and bottom of the moving rod 5 are respectively connected to the connecting rod 501 and the abutment plate 502, and the outer side of the moving rod 5 is sleeved with a first elastic element 503 whose two ends are respectively connected to the top wall of the abutment plate 502 and the bottom wall of the connecting seat 4, the connecting rod 501 is slidably connected to the connecting seat 4, and a first rack 5011 is arranged on the connecting rod 501.

[0043] Furthermore, the self-clamping assembly also includes a support plate 7 fixedly mounted on the lower side of the connecting seat 4, the support plate 7 is rotatably connected to a rotating rod 701, the rotating rod 701 is provided with a second gear 7012 and a first gear 7011 meshing with the first rack 5011, the bottom of the connecting seat 4 is slidably connected to a movable seat 8 that is movably abutted against the side wall of the pipe body 6, and the movable seat 8 is provided with a second rack 10 meshing with the second gear 7012.

[0044] Furthermore, a slide groove 9 is provided on the lower side of the connecting seat 4 , and a slider 901 is slidably connected in the slide groove 9 and movably abuts against the moving seat 8 . A second elastic element 902 is provided between the inner wall of the slide groove 9 and the slider 901 .

[0045] Furthermore, the movable seat 8 includes a seat body 801, a first elastic telescopic rod 802 connected to the seat body 801, and a support plate 803 connected to one end of the first elastic telescopic rod 802 away from the seat body 801, an airbag 804 that is movably opposed to the support plate 803 is provided on the seat body 801, and a positioning component that cooperates with the airbag 804 is provided on the movable seat 8.

[0046] Furthermore, the positioning assembly includes two pneumatic chambers 11 opened in the connecting seat 4, a catheter 8041 is arranged between the pneumatic chamber 11 and the airbag 804, a piston 111 is slidably connected in each pneumatic chamber 11, a third elastic element 112 is arranged between the piston 111 and the inner wall of the pneumatic chamber 11, a positioning rod 113 is arranged on the side of the piston 111 away from the third elastic element 112, and a first positioning hole 504 matching the positioning rod 113 is opened on the moving rod 5.

[0047] Furthermore, wear-resistant rubber pads 16 are provided on both the support plate 803 and the abutment plate 502 .

[0048] Specifically, when the hydraulic rod 3 drives the lifting mechanism to move downward, the abutment plate 502 of the lifting mechanism abuts against the top of the pipe body 6, and the abutment plate 502 drives the moving rod 5 to move upward, and the first elastic element 503 is compressed. When the abutment plate 502 moves upward, it drives the connecting rod 501 to move upward. When the connecting rod 501 moves upward, the first rack 5011 is meshed with the first gear 7011 for transmission. When the first gear 7011 rotates, it drives the second gear 7012 to rotate and meshes with the second rack 10 for transmission. The second rack 10 drives the moving seat 8 to move laterally relative to the connecting seat 4, so that the moving seat 8 approaches the side wall of the pipe body 6. Finally, when the support plate 803 abuts against the side wall of the pipe body 6, the support plate 803 is subjected to a reaction. The force moves toward the seat body 801 and squeezes the airbag 804. The air in the airbag 804 enters the pneumatic chamber 11 through the conduit 8041, and the piston 111 in the pneumatic chamber 11 is pushed. The piston 111 drives the positioning rod 113 to move toward the moving rod 5. The positioning rod 113 limits the positioning of the moving rod 5. At this time, the side walls of the pipeline body 6 abut against the moving seat 8, and the top abuts against the abutment plate 502. When the abutment plate 502 can no longer move, the abutment plate 502 cooperates with the moving seat 8 to cover and clamp the pipeline body 6, so as to realize the self-clamping work of the lifting mechanism on the pipeline body 6. There is no need for the staff to perform tedious bundling and hooking, which reduces the bundling time before and after lifting and transportation, and improves the lifting efficiency of the pipeline.

[0049] Example 3: Reference Figure 1-11 A hydraulic pipeline lifting and transportation device, based on Example 2, further, a fourth elastic element 114 is arranged between the positioning rod 113 and the piston 111, and a pull rope 115 is fixed on the positioning rod 113, and the end of the pull rope 115 away from the piston 111 passes through the connecting seat 4 and extends outward.

[0050] Specifically, after the lifting and transportation is completed, the staff only needs to pull the pull rope 115 so that the pull rope 115 applies tension to the positioning rod 113, so that the positioning rod 113 approaches the piston 111, and then the positioning rod 113 moves out of the positioning hole, thereby releasing the movement restriction of the positioning rod 113 on other structures, and then cooperates with the action of the hydraulic rod 3 so that the hydraulic rod 3 no longer presses down the pipeline body 6 through the lifting mechanism, thereby realizing the rapid disassembly and placement of the pipeline body 6, avoiding the existing work of manually untying the binding ropes, and improving the overall work efficiency of pipeline lifting and transportation.

[0051] Example 4: Reference Figure 1-11 A water conservancy pipeline lifting and transportation device, based on Example 3, further, a rotating rod 12 is rotatably connected to the connecting seat 4, a torsion spring is arranged between the rotating rod 12 and the connecting seat 4, an arc frame 121 is arranged on the rotating rod 12, and a guide plate 122 that is movably abutted against the pipeline body 6 is arranged at one end of the arc frame 121 away from the rotating rod 12, and a second positioning hole 123 that cooperates with the positioning rod 113 is opened on the rotating rod 12.

[0052] Specifically, when the hydraulic rod 3 drives the lifting mechanism to press down and clamp the pipeline body 6 through the mounting plate 301, the guide plate 122 at the bottom of the lifting mechanism first contacts the top of the pipeline body 6, and the guide plate 122 is forced to drive the arc frame 121 to rotate around the rotating rod 12. As the lifting mechanism continues to press down, the arc frame 121 returns to its original position and rotates under the action of the torsion spring, and the pipeline body 6 is placed between the two arc frames 121. When the airbag 804 is squeezed subsequently, the air in the airbag 804 is introduced into the pneumatic cavity 11, and the piston 111 in one of the pneumatic cavities 11 drives the positioning rod 113 to be inserted into the second positioning hole 123 of the rotating rod 12, so as to limit the rotation of the rotating rod 12 and the arc frame 121, so that the pipeline body 6 is placed between the two arc frames 121 during the lifting and transportation process, so as to avoid the movable seat 8 from breaking and being damaged when supporting and clamping the pipeline body 6. The arc frame 121 can still further support and limit the pipeline body 6, thereby improving the safety of pipeline lifting and transportation.

[0053] Example 5: Reference Figure 1-11 , a water conservancy pipeline lifting and transportation device, based on Example 4, further, the anti-falling component includes a screw 13 rotatably connected to the connecting seat 4, a sleeve 131 is threadedly connected to the screw 13, one end of the screw 13 is provided with a third gear 132, and the moving rod 5 is provided with a third rack 14 meshing with the third gear 132. A side plate 15 is fixedly provided on the connecting seat 4, and the end of the side plate 15 away from the connecting seat 4 is rotatably connected to a side clamping plate 151 through a pin shaft. The side clamping plate 151 is movably abutted against the end side wall of the pipeline body 6, and a second elastic telescopic rod 152 is fixedly provided on the side clamping plate 151. A connecting block 153 is fixedly provided on the top of the second elastic telescopic rod 152, and a connecting plate 154 is provided between the connecting block 153 and the sleeve 131.

[0054] Specifically, when the moving rod 5 moves up, the third rack 14 on the outer side of the moving rod 5 is meshed with the third gear 132 on the screw rod 13 for transmission, and the third gear 132 drives the screw rod 13 to rotate, and the sleeve 131 on the outer side of the screw rod 13 drives the connecting plate 154 to move axially. When the connecting plate 154 moves, the side clamping plate 151 is driven to rotate through the connecting block 153 and the second elastic telescopic rod 152, and the side clamping plate 151 rotates around the connection with the side plate 15 as the center to approach the side of the end of the pipeline body 6. After the side clamping plate 151 abuts against the pipeline body 6, the moving seat 8 has not yet abutted against the pipeline body 6. As the moving rod 5 continues to move, the sleeve 131 continues to move and squeezes the second elastic telescopic rod 152 through the connecting block 153. The second elastic telescopic rod 152 is compressed until the moving rod 5 is limited. The second elastic telescopic rod 152 drives the side clamping plate 151 to remain in contact with the pipeline body 6, effectively preventing the pipeline body 6 from falling off from the side of the device, avoiding the risk of falling during the pipeline lifting and transportation, and improving the lifting and transportation safety.
