Description

Technical Field

[0001] The utility model relates to the technical field of pipeline hoisting, in particular to an underground pipeline hoisting and positioning device. Background Art

[0002] Underground pipelines are pipes laid underground for transporting liquids, gases, or loose solids. Ancient China already used underground drainage pipes made of fired clay. Modern underground pipelines come in a wide variety of shapes, including circular, elliptical, semi-elliptical, multi-centered, oval, rectangular, and horseshoe-shaped. They are constructed using materials such as steel, reinforced concrete, prestressed concrete, brick, stone, and fiberglass. To ensure efficient construction, pipe laying requires the assistance of lifting and positioning devices.

[0003] In the process of realizing the present utility model, the inventors found that the following problems existed in the prior art and have not been solved: the existing underground pipeline lifting and positioning devices are mostly composed of two sets of steel wires sleeved on both ends of the pipeline, and lifted by a lifting mechanism. Before the sleeves are installed, there is a pipeline lifting and erection process, and the number of pipelines lifted is relatively small, which affects the lifting and positioning efficiency and is in urgent need of improvement. Therefore, we propose an underground pipeline lifting and positioning device. Utility Model Content

[0004] The purpose of the utility model is to provide an underground pipeline hoisting and positioning device, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an underground pipeline hoisting and positioning device, comprising side plates, the side plates having six groups in total, a limiting column fixedly installed in the middle of the inner side of the side plates, the limiting column movably passing through the through end of the pipeline;

[0006] A threaded barrel and a sleeve are placed between each two sets of side plates. A screw is screwed to the middle of the threaded barrel through a thread. One end of the screw is rotatably connected to the side plate on the same side through a bearing. The threaded barrel is fixedly connected to the side plate on the same side.

[0007] A clamping block is fixedly installed at the end of the limiting column, and the clamping block is fixed in a groove preset in the middle of the inner side of the side plate;

[0008] An inner rod is movably inserted into the middle of the sleeve, and the inner rod and the sleeve are respectively fixedly connected to the side plates on the same side, and the upper surface of the inner rod is engraved with scale lines;

[0009] A lifting ring is fixedly installed on the middle part of the upper surface of the side panel, which can be used in conjunction with components such as limit columns, screws and inner rods. During the use of the underground pipeline lifting and positioning device, the underground pipeline can be placed in a suitable position, and then the side panel is moved so that the limit column is inserted into the inside of the pipeline. At the same time, the screw and the threaded barrel are coordinated, and the sleeve and the inner rod are connected to limit the adjacent side panels. Then, the lifting ring is used to connect and lift the lifting mechanism. Compared with the existing bundled wire rope form, this structure does not require the pipeline lifting process, and can lift pipelines in batches, effectively improving the efficiency of underground pipeline lifting and positioning.

[0010] As an optional solution of the technical solution of the present application, a turn block is fixedly installed on the side of the screw rod close to the bearing, and limiting grooves are provided on all sides of the turn block. It can be used in conjunction with components such as bearings and turn blocks. According to the array spacing required for this batch of underground pipelines, the turn block can be rotated to drive the screw rod to rotate. The screw rod and the threaded barrel can cooperate to adjust the spacing of the side plates. The adjustable pipeline spacing design can meet the requirements of lifting and placing pipelines for different array requirements, and indirectly does not require manual prying to adjust the pipelines, and the use effect is more ideal.

[0011] As an optional solution to the technical solution of the present application, an indicator sticker is fixedly installed on the side of the upper surface of the side panel close to the lifting ring, and guiding text is printed on the indicator sticker. The operator can be informed of the corresponding procedures through the indicator sticker and guiding text, so that the lifting construction can be smooth and safe.

[0012] As an optional solution to the technical solution of the present application, bolts are movably passed through the four sides of the clamping block, and the inner ends of the bolts are screwed to the preset thread grooves on the side panels through threads. The arrangement of the bolts and the thread grooves can make the clamping block detachable for assembly, and components with matching contours can be replaced later, which has strong versatility.

[0013] As an optional solution of the technical solution of the present application, reinforcing ribs are fixedly installed on both sides of the connection between the lifting ring and the side plate, and the reinforcing ribs are a triangular structure. The reinforcing ribs can be used to increase the connection stiffness to prevent tearing and breakage.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The utility model provides an underground pipeline hoisting and positioning device. By setting a limit column, a screw and an inner rod, during the use of the underground pipeline hoisting and positioning device, the underground pipeline can be placed in a suitable position, and then the side plate is moved to make the limit column inserted into the inside of the pipeline. At the same time, the screw and the threaded barrel are matched, and the sleeve and the inner rod are inserted to limit the adjacent side plates. Then, the device is connected to the lifting mechanism through the lifting ring for lifting.
