Description

Technical Field

[0001] The utility model relates to the technical field of pipeline installation, in particular to a large-diameter pipeline hoisting and positioning integrated device. Background Art

[0002] The traditional municipal pipeline construction method is: after the foundation cushion construction is completed and accepted, use a crane to lift the concrete pipe onto the cushion with a wire rope at the edge of the foundation pit. After the pipeline is in place, in order to prevent the pipe from rolling, two groups of four wedge-shaped concrete pads should be appropriately added on both sides of the pipe. Then all debris in the socket should be removed, the adhesive on the rubber ring should be wiped clean, and non-oil lubricant should be evenly applied. The rubber ring is put on the socket, and the next section of the pipeline is lifted and installed. This traditional construction method uses a steel wire rope to pass through the pipe for lifting. When the crane lifts, the steel wire rope is affected by the gravity of the concrete, and the steel wire rope forms a triangular structure, which will damage the edge of the concrete pipe mouth and cause water leakage in the pipe in the future. Secondly, after the pipe is placed on the cushion layer, construction personnel are always required to measure and determine the center point of the pipe, and then use a crane and cushion blocks to squeeze and position it. The effect of traditional small-diameter concrete pipes is acceptable. For large-diameter concrete pipes, it is easy to cause inaccurate positioning due to external wind loads or external forces. If various problems arise in the future, the elevation needs to be adjusted section by section to ensure the elevation and plane position of the longitudinal section of the pipe. Secondary repairs are required, wasting a lot of construction costs. Utility Model Content

[0016] The present invention is further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0017] A large-diameter pipeline hoisting and positioning integrated device comprises a horizontally placed suspension rod 1 and a positioning rod 2, a connecting rod 3 is integrally formed between the ends of one side of the suspension rod 1 and the positioning rod 2, a lifting ear 4 is arranged on the top of the suspension rod 1, and a supporting positioning mechanism is arranged on the positioning rod 2.

[0018] A plurality of lifting ears 4 are arranged at intervals on the top of the suspension rod 1 , and the two sides and the middle of the top of the suspension rod 1 are respectively provided with lifting ears 4 for maintaining balance.

[0019] The supporting positioning includes supporting cylinders 5 staggeredly arranged on the upper and lower sides of the positioning rod 2. A rubber head is arranged on the output end of the supporting cylinder 5. The supporting cylinder 5 is synchronously extended to abut against the inner wall of the concrete pipe 9 to fix the concrete pipe 9.

[0020] The positioning rod 2 is composed of several sections of adjusting rods 21. Fixed grooves are provided on the end faces of adjacent adjusting rods 21. Telescopic cylinders 6 are arranged in two opposite fixed grooves. The tail of the cylinder body of the telescopic cylinder 6 is fixed in the fixed groove on one side, and the piston end of the telescopic cylinder 6 is fixed in the fixed groove on the other side. The telescopic cylinder 6 is extended and retracted to drive the adjusting rod 21 on the piston side to move. When the piston stroke of the telescopic cylinder 6 is zero, the end faces of the two adjacent adjusting rods 21 are in contact. During lifting, the positioning rod 2 is located in the section of concrete pipe 9. When the concrete pipes 9 at both ends are docked, the telescopic cylinder 6 is extended to drive the adjusting rod 21 to extend forward into the other section of concrete pipe 9. Different supporting cylinders 5 are controlled to perform detailed adjustments on the two sections of concrete pipes 9 for easy docking. A hydraulic generator and a signal receiver connected to the supporting cylinder 5 and the telescopic cylinder 6 are arranged on the connecting rod 3. The operator is provided with a remote control to control the work of the supporting cylinder 5 and the telescopic cylinder 6.

[0021] A horizontal fixed platform 7 is provided on the top of the suspension rod 1, and a bubble level 8 is provided on the horizontal fixed platform 7. All the supporting cylinders 5 work synchronously during lifting, so the concrete pipe 9 is axially parallel to the positioning rod 2 and the suspension rod 1. When hoisted onto a horizontal cushion, the bubble level 8 can be observed to observe whether the concrete pipe 9 is placed horizontally, so as to make timely adjustments, thereby avoiding the tedious adjustment work caused by the failure of the subsequent concrete pipes at both ends to be smoothly connected due to temporary falling of debris on the cushion.

[0022] Tie the steel wire rope to the lifting lug, insert the positioning rod into the concrete pipe, control the supporting oil cylinder to extend synchronously through the remote control to fix the concrete pipe, and the crane drives the steel wire rope to place the concrete pipe on the cushion. After the pipe mouth and rubber ring are processed, the docking work is carried out. The positioning rod is extended to the other section of the concrete pipe, and the supporting oil cylinder is used to make detailed adjustments to the two sections of the concrete pipe so that the pipe mouths are opposite to each other to prevent damage to the pipeline and facilitate the subsequent docking of the pipe mouths.

[0023] The above description is only a preferred feasible embodiment of the present utility model, and does not limit the scope of rights of the present utility model. All equivalent changes made using the contents of the present utility model specification and its drawings are included in the scope of rights of the present utility model.
