Description

Major diameter concrete pipe hoist device

Technical Field

The utility model belongs to the technical field of the drain pipe construction among the municipal works, concretely relates to a device for hoisting reinforced concrete drain pipe.

Background

Rain and sewage pipelines in municipal drainage engineering mostly adopt large-diameter reinforced concrete pipes. Hoisting holes are reserved on two sides of the concrete pipeline when prefabrication is performed, and bolts connected with hoisting ropes are inserted into the hoisting holes on the two sides during pipeline hoisting. In order to ensure the pipeline sealing, the hoisting hole must be a blind hole and cannot be set too deep due to the limitation of the wall thickness of the pipeline, so that a bolt inserted into the hoisting hole is easy to fall off in the hoisting process, and certain potential safety hazard is caused to hoisting construction; in addition, in the process of pipeline installation, the pipeline can be firmly installed by rotating the pipeline sometimes, and the pipeline cannot be rotated by lifting the pipeline through the lifting hole.

Detailed Description

As shown in fig. 1, 2, 3 and 4, the present invention comprises 3 main pulleys and a bearing plate; the 3 main pulleys are arranged up and down and sequentially comprise an upper pulley 1, a middle pulley 2 and a lower pulley 3 from top to bottom, two sides of the 3 main pulleys are respectively provided with a connecting plate 4, and rotating shafts of the 3 main pulleys are respectively fixedly connected with the two connecting plates 4; the bearing plate 5 is rectangular, a strip-shaped through hole 6 is longitudinally formed in the middle of the bearing plate 5, two bearing pulleys 7 are symmetrically arranged on the top surfaces of two ends of the

bearing plate

5, and 4 auxiliary pulleys 8 are symmetrically arranged on the bottom surfaces of two ends of the bearing plate; 3 main pulleys are positioned above the bearing plate and are right opposite to the strip-shaped through hole on the bearing plate, an annular auxiliary lifting rope 9 is wound between the middle pulley 2 and the two bearing pulleys 7, a main lifting rope 10 is wound on the lower pulley 3, two ends of the main lifting rope 10 penetrate through the strip-shaped through hole 6 on the bearing plate and extend to the lower part of the bearing plate, and two ends of the main lifting rope are respectively connected with a bolt 11; an annular safety rope 12 is wound between every two opposite auxiliary pulleys at the bottom of the bearing plate 5 along the longitudinal direction of the bearing plate. The bottom of the circular safety rope 12 hangs down, and the height of the hanging part is lower than that of the lower end of the main lifting rope.

The two auxiliary pulleys 8 located at the same end of the bottom of the bearing plate 5 are symmetrical about the longitudinal axis of the bearing plate, and the 4 auxiliary pulleys located at the two ends of the bearing plate are symmetrical about the transverse axis of the bearing plate.

As shown in fig. 5 and 6, when the concrete pipe 13 is hoisted, a hoisting rope 14 is wound around the upper pulley 1, and both ends of the hoisting rope 14 are respectively provided with a hoisting ring and connected to a hook 15 of a crane; inserting the bolts 11 at the two ends of the main lifting rope 10 into the hoisting holes 16 at the two sides of the concrete pipe respectively, and sleeving the two safety ropes 12 below the concrete pipe respectively after the concrete pipe 13 is lifted off the ground by a crane; as shown in fig. 6, in the hoisting process, once the bolt falls off from the hoisting hole, the concrete pipe 13 is received by the two safety ropes 12, so that the safety accident caused by the concrete pipe falling to the ground can be avoided.

After the concrete pipe is lifted to a designated position, the concrete pipe is butted with the previously installed concrete pipe, in the butting process, if a butting port can not be smoothly butted, the concrete pipe generally needs to be rotated to find an optimal matching angle, at the moment, the concrete pipe can be firstly placed on the ground, the bolt 11 is taken out after the main lifting rope 10 is loosened, as shown in fig. 6, the concrete pipe 13 is lifted again, at the moment, the concrete pipe is lifted by the safety rope 12 and is butted with the previously installed concrete pipe again, and the safety rope 12 is annular, so that the concrete pipe can be rotated randomly during butting until an angle capable of smoothly butting the concrete pipe is found, and the concrete pipe is installed in place.
