Technical Field

[0001] The utility model relates to the technical field of pipeline laying, in particular to a pipeline laying device. Background Art

[0002] In modern society, there are various pipeline facilities for discharging natural gas, domestic sewage and tap water. In order to reduce the floor area occupied by pipelines, pipe burying operations need to be carried out underground. Therefore, in order to ensure the laying efficiency, a laying device is required.

[0003] The existing pipeline laying devices have certain drawbacks. Since the laid pipelines have a certain length and weight, manpower cannot push the pipelines for laying and docking. And the existing hoisting structures cannot automatically center the hoisting, and at the same time, the hoisted pipelines cannot be lifted and lowered evenly. As a result, a large amount of energy is required to adjust the position when the pipelines are laid and spliced, thus affecting the efficiency of laying construction. Therefore, a pipeline laying device is urgently needed. Summary of the Utility Model

[0004] To solve the above problems, the utility model provides a pipeline laying device, which is realized by the following technical solutions.

A suspension mechanism arranged on the hook is used for hoisting the pipeline main body. The suspension mechanism includes an arc-shaped support plate. Both sides of the arc-shaped support plate are fixedly connected with wire ropes. One ends of the two wire ropes are fixed with hanging rings sleeved on the hook. The device also includes a lifting mechanism for adjusting the lifting of the hoisted pipeline main body.

[0006] Further, the lifting mechanism includes an internally threaded pipe, a transmission rod and a servo motor. One end of the internally threaded pipe is fixedly connected with a first bevel gear, and the internally threaded pipe is rotatably connected to the transmission box. The other end of the lead screw penetrates and is in threaded cooperation with the internally threaded pipe.

[0007] Further, there are two transmission rods rotatably connected to both ends inside the transmission box. A second bevel gear fixed to one end of the transmission rod is meshed with the first bevel gear, and a third bevel gear is fixedly connected to the other end of the transmission rod.

[0008] Further, the servo motor is fixedly connected to the central position of the top of the transmission box. A fourth bevel gear fixed to the output shaft of the servo motor is meshed with the third bevel gear.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1-3 shown, the present utility model has the following specific embodiments.

[0023] Embodiment:

[0024] A pipeline laying device includes a pipeline main body, and also includes a steel truss 1. A transmission box 2 is fixedly connected to the top of the steel truss 1. Both ends of the transmission box 2 are movably connected with lead screws 3. One end of the lead screw 3 passing through the steel truss 1 is rotatably connected with a hook 31. A suspension mechanism arranged on the hook 31 is used for hoisting the pipeline main body. The suspension mechanism includes an arc-shaped support plate 4. Both sides of the arc-shaped support plate 4 are fixedly connected with wire ropes 41. A suspension ring 42 fixed at one end of the two wire ropes 41 is sleeved on the hook 31. It also includes a lifting mechanism, and the lifting mechanism is used to adjust the lifting of the hoisted pipeline main body.

[0025] By adopting the above technical solution, when using the device, first use the arc-shaped support plate 4 arranged by the suspension mechanism to sleeve on the pipeline main body, which is convenient for the pipeline main body to be centered and hoisted. Then make the arc-shaped support plate 4 hang on the hook 31 through the suspension ring 42 connected by the wire rope 41. Then drive the connected pipeline main body to rise through the lifting mechanism. Then move the steel truss 1 to the laying position. Finally, by adjusting the lifting mechanism, it can drive the hoisted pipeline main body to lift and lower smoothly, which is convenient for the hoisted pipeline main body to be quickly docked and installed with the laid pipeline, can improve the efficiency of pipeline laying construction, and can reduce labor force at the same time.

[0026] Specifically, the lifting mechanism includes an internally threaded tube 21, a transmission rod 22 and a servo motor 23. One end of the internally threaded tube 21 is fixedly connected with a first bevel gear 211, and the internally threaded tube 21 is rotatably connected to the transmission box 2. The other end of the lead screw 3 penetrates through and is in threaded cooperation with the internally threaded tube 21;

[0027] There are two transmission rods 22 rotatably connected to both ends inside the transmission box 2. A second bevel gear 221 fixed at one end of the transmission rod 22 is meshed and connected with the first bevel gear 211. The other end of the transmission rod 22 is fixedly connected with a third bevel gear 222;

[0028] The servo motor 23 is fixedly connected to the center position of the top of the transmission box 2. A fourth bevel gear 231 fixed to the output shaft of the servo motor 23 is meshed and connected with the third bevel gear 222;

[0029] The lead screw 3 passes through the positioning through-hole 11 opened at the top of the steel truss 1, and sliders 12 are fixedly connected to both sides inside the positioning through-hole 11. The hooks 31 formed on the outer surface of the lead screw 3 are in sliding fit with the sliders 12.

[0030] By adopting the above technical solution, the lifting of the suspended pipeline main body can be adjusted. That is, by turning on the servo motor 23, the fourth helical gear 231 can be driven to rotate. The fourth helical gear 231 can drive two meshing third helical gears 222 to rotate simultaneously. The third helical gear 222 can drive the second helical gear 221 to rotate through the transmission rod 22. The second helical gear 221 can drive the meshing first helical gear 211 to rotate. The first helical gear 211 can drive the internal thread tube 21 to rotate on the transmission box 2. Since the lead screw 3 is in threaded fit with the internal thread tube 21, at the same time, the sliders 12 fixed inside the positioning through-hole 11 can be limited to slide within the hooks 31, so that the lead screw 3 can be limited to lift on the steel truss 1. Then, the rotating internal thread tube 21 can drive the lead screw 3 in threaded fit to lift on the steel truss 1. The lead screw 3 can drive the suspension mechanism to lift, so that the suspension mechanism can drive both ends of the suspended pipeline main body to lift synchronously and balance, avoiding the inclination of the pipeline main body during laying.

[0031] Specifically, a moving wheel set 13 is fixedly connected to the bottom of the steel truss 1.

[0032] By adopting the above technical solution, the provided sliders 12 can facilitate the pushing of the steel truss 1 to move, enable the steel truss 1 to change its position for hoisting, and save effort.
