Problems solved by technology

[0002] At present, when installing ductile iron pipes, it is generally used with a small excavator or a traditional hand-pulled (hand pull) hoist. These two methods are only suitable for outdoor installation with a large working space. In the case of a narrow space, such as in a tunnel, due to the small installation space, these two methods cannot be operated at all, which brings great difficulties to the installation and construction of pipelines in a small space

Embodiment Construction

[0034] Such as Figure 1 to Figure 3As shown, the takeover well 3 is used to accept the ductile iron pipe 6 lowered and installed from the lower pipe well 12 . The main hoisting device 1 located on the ground of the takeover shaft 3 and the auxiliary hoisting device 13 located on the ground of the lower pipe shaft 12 . The right side of the main hoisting device 1 and the left side of the auxiliary hoisting device 13 are respectively provided with a left fixed pulley 2 a and a right fixed pulley 2 b opposite to each other. The connecting pipe shaft 3 is connected with the bottom of the lower pipe shaft 12 to form a tunnel 14. The left and right fixed pulleys 2c and 2d are arranged symmetrically on the inner walls of the left and right ends of the tunnel 14 along its axial direction. To connect, the right end is connected with the wire rope end coupler 9 after bypassing the left fixed pulley 2a and the lower left fixed pulley 2c successively. Also includes auxiliary wire rope ...

Abstract

The invention discloses a large-diameter pipeline installation device and a pipeline installation method utilizing the same. The installation device comprises a main winding device and an auxiliary winding device which are located on the ground of a receiving tube well and the ground of a lower tube well. One side of the main winding device and one side of the auxiliary winding device are oppositely provided with a left side fixed pulley and a right side fixed pulley. The bottom of the receiving tube well and the bottom of the lower tube well are made communicated to form a tunnel. The two ends of the tunnel are symmetrically provided with a left lower fixed pulley and a right lower fixed pulley. The left end of a main steel wire rope is connected with the main winding device, the right end of the main steel wire rope winds around the left side and the left lower fixed pulley to be connected with a coupler at the tail end of the steel wire rope, the right end of an auxiliary steel wire rope is connected with the auxiliary winding device, the left end the auxiliary steel wire rope winds around the right and the right lower fixed pulley to be connected with a bellmouth check block, and the coupler and the bellmouth check block are connected with a chain block A. A nodular cast iron pipe is horizontally arranged along the tunnel. The coupler and the chain block A are arranged in the nodular cast iron pipe. The bellmouth check block makes contact with a bellmouth of the nodular cast iron pipe. According to the large-diameter pipeline installation device and the pipeline installation method utilizing the large-diameter pipeline installation device, the structure is simple, operation is easy and convenient, pipeline installation is reliable and the labor intensity of workers is low.

Description

technical field [0001] The invention relates to the technical field of laying or recovering pipes underground, in particular to a large-diameter pipe installation device and a pipe installation method using the same. Background technique [0002] At present, when installing ductile iron pipes, it is generally used with a small excavator or a traditional hand-pulled (hand pull) hoist. These two methods are only suitable for outdoor installation with a large working space. In the case of a narrow space, such as in a tunnel, due to the small installation space, these two methods cannot be operated at all, which brings great difficulties to the installation and construction of pipelines in a small space. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a large diameter pipeline installation device with simple structure, easy operation, reliable pipeline installation and low labor intensity. [0004] The large-diamete...
