Description

Technical Field

[0002] Water conservancy projects are projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can pipes be laid during construction to form fixed water flow channels. Pipe laying machines are needed to lay the pipes. Generally, the pipes used in water conservancy projects are of large mass, and it is relatively inconvenient to carry them manually. Generally, auxiliary tools such as cranes are required to lift the pipes.

[0028] In order to make the purpose, technical solution and advantages of the utility model clearer and more understandable, the technical solution of the utility model will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1 , Figure 5 , Figure 7 As shown, the utility model provides a lifting device for laying pipelines in water conservancy engineering construction, including a base, a counterweight structure, two L-shaped plates 3, a first adjustment component, a second adjustment component, a third adjustment component and two lifting claws, the two L-shaped plates 3 are slidably mounted at the two ends of the base, a guide rod 4 is horizontally fixed between the two L-shaped plates 3, and the two lifting claws are slidably connected to the guide rod 4. The first adjustment component is used to drive the two lifting claws to move closer to or away from each other along the axial direction of the guide rod 4, the second adjustment component is used to drive the two L-shaped plates 3 to move synchronously along the radial direction of the guide rod 4, and the third adjustment component is used to drive the two lifting claws to perform lifting and lowering movements. The counterweight structure includes two counterweight units, which are respectively installed at the two ends of the base, and the counterweight units include a counterweight plate 15 and a reverse transmission component, which can drive the counterweight plate 15 to move in the reverse direction when the L-shaped plate 3 moves.

[0031] Since the guide rod 4 is fixedly connected to the L-shaped plate 3 and the lifting claw is slidably connected to the guide rod 4, when the second adjusting component drives the two L-shaped plates 3 to move synchronously along the radial direction of the guide rod 4, it can also drive the lifting claw to move synchronously in the radial direction; the first adjusting component can drive the two lifting claws to approach or move away from each other axially along the guide rod 4, thereby changing the distance between the two lifting claws. When facing pipes of different lengths and weights, the distance between the lifting claws can be adjusted to ensure the stability of the pipes during the lifting process; the third adjusting component can drive the two lifting claws to perform lifting and lowering movements, which is convenient for lifting and lowering pipes.

[0032] When it is necessary to place a pipe in a ditch that is inconvenient to cross, the second adjustment component can drive the pipe to move toward the ditch outside the device. At the same time, the reverse transmission component can drive the counterweight plate 15 to move in the opposite direction, thereby avoiding the situation where the center of gravity of the device shifts and causes overturning, which is safer and more reliable.

[0033] The lifting claw comprises a transverse frame 8, a first bidirectional hydraulic rod 9 and two arc plates 10, both of which are slidably connected to the transverse frame 8, a cylinder of the first bidirectional hydraulic rod 9 is fixedly connected to the transverse frame 8 and two telescopic ends thereof are respectively fixedly connected to the two arc plates 10. The first bidirectional hydraulic rod 9 can drive the two arc plates 10 to move closer to or away from each other, thereby clamping or loosening the pipeline.

[0034] The third adjustment component includes two hydraulic rod units and two sliders 6. The two sliders 6 are slidably installed on the guide rod 4. The two hydraulic rod units are respectively connected to the two sliders 6. The hydraulic rod unit includes two multi-section hydraulic rods 7. The cylinder bodies of the two multi-section hydraulic rods 7 are fixedly connected to the sliders 6 and the telescopic ends thereof are fixedly connected to the nearby cross frame 8.

[0035] After the multi-stage hydraulic rod 7 is started, it can drive the cross frame 8 to move up and down, thereby causing the arc plate 10 to move up and down, thereby realizing the lifting and lowering of the pipeline.

[0036] The first adjustment assembly includes two symmetrically arranged first hydraulic rods 5 , the cylinder body of the first hydraulic rod 5 is fixedly connected to the top of the L-shaped plate 3 and the telescopic end thereof is fixedly connected to the nearby sliding block 6 .

[0037] Since the two first hydraulic rods 5 are symmetrically arranged, when the telescopic end is telescoped, the two slide blocks 6 can be driven to move in opposite directions along the axis direction of the guide rod 4, thereby making the lifting claws approach or move away from each other.

[0038] The second adjustment assembly includes two slide rails 2 and two second hydraulic rods 16. The two slide rails 2 are fixedly mounted at both ends of the base, and the bottom ends of the two L-shaped plates 3 are slidably connected to the two slide rails 2. The two second hydraulic rods 16 are respectively mounted at both ends of the base, and the cylinder bodies of the two second hydraulic rods 16 are fixedly connected to the base and the telescopic ends thereof are fixedly connected to the L-shaped plates 3.

[0039] The length direction of the slide rail 2 is in the same direction as the radial direction of the guide rod 4. When the telescopic end of the second hydraulic rod 16 is extended and retracted, the L-shaped plate 3 can be pushed to move along the length direction of the slide rail 2, thereby allowing the pipe on the lifting claw to extend outside the device, making it easier to place the pipe in the ditch outside the device.

[0040] The reverse transmission assembly includes a first rack 11, a second rack 13, a positioning block 12 and a gear 14. The first rack 11 is fixedly connected to the bottom end of the L-shaped plate 3, the positioning block 12 is fixedly mounted on the base, the second rack 13 is slidably connected to the positioning block 12, the gear 14 is rotatably mounted on the base and is located between the first rack 11 and the second rack 13, the two sides of the gear 14 are respectively meshed with the first rack 11 and the second rack 13, and the counterweight plate 15 is fixedly connected to the second rack 13.

[0041] When the L-shaped plate 3 moves, since the first rack 11 is fixedly connected to the bottom end of the L-shaped plate 3, the first rack 11 can move in the same direction as the L-shaped plate 3. Since the gear 14 is meshed with the first rack 11, the gear 14 will rotate under the drive of the first rack 11. Since the gear 11 is meshed with the second rack 13 and is located between the first rack 11 and the second rack 13, the gear 14 can drive the second rack 13 to move in the opposite direction relative to the first rack 11 when it rotates, thereby driving the counterweight plate 15 to move in the opposite direction relative to the pipe, thereby preventing the center of gravity of the device from shifting and tipping over.

[0042] In summary, the working process of the device is as follows: first, the multi-section hydraulic rod 7 is started to drive the horizontal frame 8 to move downward, and then the first bidirectional hydraulic rod 9 is started to drive the arc plates 10 to move away from each other, until the two arc plates 10 on the lifting claws are located on both sides of the pipeline, the first bidirectional hydraulic rod 9 is contracted, and the arc plates 10 are driven to clamp the pipeline, and then the multi-section hydraulic rod 7 is contracted in the opposite direction to drive the pipeline to move upward, and then the mobile device straddles the ditch, and then the multi-section hydraulic rod 7 can be started again to extend, the pipeline is lowered into the ditch, and the first bidirectional hydraulic rod 9 is started to drive the arc plates 10 to open and release the pipeline;

[0043] When the ditch for laying the pipeline is inconvenient to cross, first start the multi-section hydraulic rod 7 and the first bidirectional hydraulic rod 9 to drive the lifting claw to move down, clamp the pipeline and then raise it, and then open the second hydraulic rod 16 to drive the pipeline to move toward the ditch. In this process, the L-shaped plate 3 can drive the first rack 11 to move, and after being transmitted by the gear 14, it drives the second rack 13 to move in the opposite direction, so that the counterweight block 15 and the pipeline move in the opposite direction to prevent the device from tipping over. After the pipeline moves to the top of the ditch, stop the second hydraulic rod 16, start the multi-section hydraulic rod 7 and the first bidirectional hydraulic rod 9, drive the pipeline to move down into the ditch and release the pipeline.

[0044] Example 2

[0045] like Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, the base includes two symmetrically arranged bottom plates 1, and the two bottom plates 1 are symmetrically provided with slide grooves 21, in which T-blocks 20 are slidably embedded, and telescopic plates 19 are fixedly connected to the T-blocks 20. A partition 17 is symmetrically arranged on the bottom surface of the bottom plate 1, and a second bidirectional hydraulic rod 18 is fixedly connected to the telescopic plate 19, and the two telescopic ends of the second bidirectional hydraulic rod 18 are fixedly connected to the two partitions 17 respectively.

[0046] In some examples, both base plates 1 are provided with moving wheels and tapered rods. The moving wheels can facilitate the movement of the device, and the tapered rods can be inserted into the ground to facilitate the positioning of the device.

[0047] When the length of the pipe to be lifted exceeds the length of the entire base, the second bidirectional hydraulic rod 18 can be started. The two telescopic ends of the bidirectional hydraulic rod 18 can push the two partitions 17, thereby causing the two bottom plates 1 to move in opposite directions. At this time, the T-block 20 slides in the slide groove 21. On the one hand, it can guide the movement of the two bottom plates 1. On the other hand, the T-block 20 can interfere with the end of the slide groove 21 to prevent the two bottom plates 1 from being completely disconnected. In this way, the length of the base can be increased to meet the lifting requirements of the pipe.
