Description

Technical Field

[0001] This utility model relates to the field of pipeline laying technology, and in particular to a lifting and guiding hydraulic pipeline laying device. Background Technology

[0002] In water conservancy projects, the laying of large pipelines, such as water pipes and culverts, often requires precise positioning in trenches or pre-set locations using hoisting equipment. The stability and accuracy of this equipment directly affect the quality of pipeline installation and project safety. However, traditional hoisting methods often rely on gantry cranes or cranes to suspend pipelines at a single point. During this process, external forces can cause the pipelines to slip, shift, or collide and become damaged. Furthermore, when the pipelines are subjected to wind, operational impacts, or unexpected swings, they are highly susceptible to slippage and falls, posing a significant threat to the lives and property of workers. Additionally, existing clamping devices generally suffer from unstable clamping force and a lack of anti-fall-off structures, making them prone to loosening during lifting or horizontal movement. This not only threatens construction safety but may also damage the pipe walls. Moreover, when the pipeline enters the trench, repeated manual adjustments are required, lacking effective guiding mechanisms to assist in horizontal alignment. This not only results in low efficiency and poor positioning accuracy but also increases pipe wear due to friction. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a lifting-guided water pipeline laying device, which has the advantages of simple structure, stable lifting and high laying efficiency.

[0004] The technical solution adopted by this utility model is as follows: it includes a gantry crane and uprights. A sliding groove is provided on one side of the gantry crane. The bottom of the uprights is fixed to the top of the gantry crane. There are three sets of uprights. The characteristic is that: a rotating motor is fixedly installed on one side of one set of uprights. A rotating shaft is installed at the output end of the rotating motor. The other end of the rotating shaft passes through two sets of uprights and is rotatably installed on another set of uprights. Three winding frames are fixedly installed on the outside of the rotating shaft. A lifting rope is fixedly connected to the outside of the winding frame. A limit frame is fixedly installed at the other end of one of the lifting ropes. An anti-fall-off clamping component is fixedly installed inside the limit frame. Guide components are fixedly installed at the other ends of the other two lifting ropes, and the guide components are slidably disposed inside the sliding groove.

[0005] Preferably, in order to drive the bidirectional screw to rotate, the anti-drop clamping assembly includes a servo motor and a bidirectional screw with reversed threads at both ends. The servo motor is fixedly installed on one side of the limiting frame, one end of the bidirectional screw is installed on the output end of the servo motor, and the other end of the bidirectional screw is rotatably installed on the other side inside the limiting frame.

[0006] Preferably, in order to adjust the position of the two connecting brackets so as to clamp pipelines of different diameters, a slider is slidably installed on the outside of the bidirectional screw, the slider is threadedly connected to the bidirectional screw, a connecting bracket is fixed at the bottom of the slider, a spring is fixed on one side inside the connecting bracket, and a movable plate is fixedly installed on the other end of the spring.

[0007] Preferably, in order to automatically start and stop the first telescopic part, a connecting rod is fixed to the other side of the moving plate, and a rubber pad is fixedly installed at the other end of the connecting rod through the connecting frame. A control switch is installed inside one side of the connecting frame.

[0008] Preferably, in order to limit the clamped pipeline and prevent the pipeline from falling off, a groove is provided on the other side of the connecting frame, and a first telescopic part is fixedly installed inside the groove. A limit plate is fixed at the other end of the first telescopic part, and the limit plate is located below the rubber pad.

[0009] Preferably, in order to improve the service life of the rubber pad, the rubber pad is made of wear-resistant rubber material.

[0010] Preferably, in order to guide the pipeline, the guiding assembly includes a sliding plate, the top of which is fixedly installed at the other end of the suspension rope, the sliding plate is slidably engaged inside the groove, and a second telescopic part is fixedly installed on one side of the sliding plate.

[0011] Preferably, in order to adjust the height of the guide frame to adapt to the pipeline laying requirements of different depths, the other end of the second telescopic part is fixed with a guide frame, and a guide roller is rotatably installed inside the guide frame.

[0012] The beneficial effects of this utility model are as follows: the servo motor in the anti-drop clamping assembly drives the bidirectional screw to move the sliders in opposite directions. The connecting frame at the bottom of the slider pushes the connecting rod through the spring buffer to make the rubber pad flexibly clamp the pipeline. The first telescopic part drives the limiting plate to form a physical block under the rubber pad, which constitutes a double insurance to prevent the pipeline from accidentally slipping off, significantly improving the safety of hoisting and protecting the pipe wall. At the same time, the sliding plates of the two guide components slide along the slide groove, and cooperate with the second telescopic part to adjust the position of the guide frame, so that the internal guide rollers support the pipeline from both sides and reduce the moving friction, realizing the precise guidance and smooth translation of the laying path. Thus, the pipeline can be lifted and positioned efficiently and smoothly, which is highly practical. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1-5 As shown, this embodiment provides a lifting and guiding water pipeline laying device, including a gantry crane 1 and upright plates 2. A sliding groove 10 is provided on one side of the gantry crane 1. The bottom of the upright plates 2 is fixed to the top of the gantry crane 1. There are three sets of upright plates 2. The feature is that: a rotating motor 3 is fixedly installed on one side of one set of upright plates 2. A rotating shaft 4 is installed at the output end of the rotating motor 3. The other end of the rotating shaft 4 passes through two sets of upright plates 2 and is rotatably installed on another set of upright plates 2. Three winding frames 5 are fixedly installed on the outside of the rotating shaft 4. The rotating motor 3 drives the rotating shaft 4 to drive the three winding frames 5 to work together, which can efficiently and smoothly lift and position the pipeline. A lifting rope 6 is fixedly connected to the outside of the winding frame 5. A limit frame 7 is fixedly fixed at the other end of one of the lifting ropes 6. The limit frame 7 has a limiting effect on the anti-falling clamping component 8. The anti-falling clamping component 8 is fixedly installed inside the limit frame 7. The other two lifting ropes 6 are fixedly installed with guide components 9, and the guide components 9 are slidably arranged inside the sliding groove 10.

[0021] In practical use, the water pipeline is first placed in the anti-drop clamping assembly 8. The anti-drop clamping assembly 8 can not only stably clamp pipelines of different diameters, but also prevent the pipeline from accidentally slipping during the movement of the gantry crane 1, thus improving safety. Then, the rotating motor 3 is started, and the output end of the rotating motor 3 drives the rotating shaft 4 to rotate. The three winding frames 5 fixedly installed on the outside of the rotating shaft 4 rotate accordingly, thereby winding the lifting rope 6 around the winding frame 5. The limiting frame 7 and the guide assembly 9 connected to the other end of the lifting rope 6 rise under the traction of the lifting rope 6. Under the action of the guide assembly 9, the pipeline laying path is accurately guided and smoothly moved, thus enabling efficient and stable lifting and positioning of the pipeline. When the pipeline moves to the predetermined position, the rotating motor 3 reverses, the winding frame 5 releases the lifting rope 6, and the pipeline slowly descends under the action of gravity until it is accurately laid in the trench or the preset position, which significantly improves the safety and efficiency of water pipeline laying operations.

[0022] As a technical optimization solution of this utility model, specifically as follows: Figure 4 As shown, the anti-drop clamping assembly 8 includes a servo motor 801 and a bidirectional screw 802 with reversed threads at both ends. The servo motor 801 is fixedly mounted on one side of the limiting frame 7. One end of the bidirectional screw 802 is mounted on the output end of the servo motor 801, and the other end of the bidirectional screw 802 is rotatably mounted inside the limiting frame 7 on the other side. A slider 803 is slidably mounted on the outside of the bidirectional screw 802. The slider 803 is threadedly connected to the bidirectional screw 802 and is located inside the limiting frame 7. The limiting frame 7 has a limiting effect on the slider 803, allowing the slider 803 to move on the bidirectional screw 802 instead of rotating. A connecting frame 804 is fixed to the bottom of block 803. A spring 805 is fixed to one side inside the connecting frame 804. A movable plate 806 is fixed to the other end of the spring 805. A connecting rod 807 is fixed to the other side of the movable plate 806. A rubber pad 808 is fixed to the other end of the connecting rod 807 through the connecting frame 804. A control switch 809 is installed on one side inside the connecting frame 804. A groove is opened on the other side of the connecting frame 804. A first telescopic part 810 is fixedly installed inside the groove. A limit plate 811 is fixed to the other end of the first telescopic part 810. The limit plate 811 is located below the rubber pad 808. The rubber pad 808 is made of wear-resistant rubber.

[0023] In use, the servo motor 801 is started, and its output drives the bidirectional screw 802 to rotate. Because the threads at both ends of the bidirectional screw 802 are reversed, the two sliders 803 move towards each other. The connecting frame 804 at the bottom of the sliders 803 moves accordingly. The spring 805 inside the connecting frame 804 pushes the moving plate 806. The connecting rod 807 on the other side of the moving plate 806 drives the rubber pad 808 closer to the pipeline until the rubber pad 808 is tightly fitted to the pipeline. The rubber pad 808 is made of wear-resistant rubber material and can... It can increase the friction between the rubber pad and the pipeline, improve the clamping stability, and at the same time, the flexible material of the rubber pad 808 can avoid damage to the pipeline. When the rubber pad 808 contacts the pipeline and is compressed to a certain extent, the moving plate 806 triggers the control switch 809 inside the connecting frame 804. The control switch 809 controls the start and stop of the first telescopic part 810. The limiting plate 811 fixed at the other end of the first telescopic part 810 forms a physical block under the rubber pad 808, which constitutes a double insurance to prevent the pipeline from accidentally slipping, further improving the safety of hoisting.

[0024] As a technical optimization solution of this utility model, specifically as follows: Figure 5 As shown, the guide assembly 9 includes a sliding plate 901. The top of the sliding plate 901 is fixedly installed at the other end of the suspension rope 6. The sliding plate 901 is slidably engaged inside the slide groove 10. A second telescopic part 902 is fixedly installed on one side of the sliding plate 901. The stretching and contraction of the second telescopic part 902 can flexibly adjust the position of the guide frame 903, thereby guiding pipelines of different diameters. The other end of the second telescopic part 902 is fixedly installed with the guide frame 903. A guide roller 904 is rotatably installed inside the guide frame 903.

[0025] In use, the lifting rope 6 can adjust the height of the sliding plate 901 according to the laying requirements, so that the guide frame 903 can adapt to pipeline laying operations at different depths. The guide roller 904 inside the guide frame 903 supports the pipeline from both sides and rolls during pipeline movement, which significantly reduces the frictional resistance between the pipeline and the guide frame 903, realizes precise guidance and smooth translation of the laying path, and ensures that the pipeline can move smoothly and accurately to the predetermined position, effectively improving the efficiency and accuracy of water conservancy pipeline laying operations.
