A kind of mud-water conveying pipeline extension apparatus of Big diameter slurry shield, including support construction frame, shield machine Steel pipe, hose, semi-circular bracket, dragging car, hoist engine and tunnel steel tube, the support construction frame include superstructure frame, in Layer structure-steel framing and understructure frame, media layer damage frame front end are provided with hoist engine, and media layer damage frame rear end is provided with Sliding rail is equipped with dragging car on the sliding rail, and the hoist engine is connect with dragging car by cable, is fixed in the dragging car Semi-circular bracket, the semi-circular bracket inside are provided with the carrying roller for reducing hose force of sliding friction;The hose sliding Across semi-circular bracket, described hose one end connects shield machine steel pipe, the shield machine penstock installation in support construction top of the trellis, The hose other end connects tunnel steel tube, and the tunnel steel tube is installed on tunnel, the shield machine steel pipe and the tunnel Steel pipe horizontal parallel, the support construction frame forward horizontal is mobile, and tunnel steel tube is fixed, realizes that the hose pulls semicircle Shape bracket and dragging car horizontal movement backward.
As a kind of optimization of the utility model, the understructure of the support construction frame, which sets up to be equipped with, enhances firm power Reinforce column.
As a kind of optimization of the utility model, the junction periphery of the hose and shield machine steel pipe is cased with reinforcing pipe, Shield machine steel pipe is fixed in described reinforcing pipe one end, and the other end is fixed on the superstructure frame of the support construction frame.
As a kind of optimization of the utility model, the bottom setting of the semi-circular bracket is reduced the pulley of frictional force.
As a kind of optimization of the utility model, the rolling for reducing hose sliding friction is provided with below the hose Cylinder.
The utility model has the beneficial effects that:
The mud-water conveying pipeline extension apparatus of the Big diameter slurry shield of the utility model is using simple support Structure-steel framing, the support construction frame are arranged on shield machine, reduce occupied area, while connecting shield machine steel pipe by hose And tunnel steel tube, when realizing that shield machine continuously moves forward using semi-circular bracket, dragging car, without dragging tunnel steel Pipe, can keep hose to connect with tunnel steel tube.Relatively existing extension apparatus, extension apparatus provided by the utility model are not only tied Structure is simple, low cost, is hardly damaged simultaneously, dismounting is even more convenient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model extension apparatus original state;
Fig. 2 is the structural schematic diagram of the utility model extension apparatus end-state.
Appended drawing reference: 1, media layer damage frame;2, hoist engine;3, dragging car;4, semi-circular bracket;5, hose;6, shield machine Steel pipe;7, reinforcing pipe;8, carrying roller;9, superstructure frame;10, understructure frame;11, column is reinforced.
Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model:
As shown in Figure 1, a kind of mud-water conveying pipeline extension apparatus of Big diameter slurry shield, including support construction Frame, shield machine steel pipe 6, hose 5, semi-circular bracket 4, dragging car 3, hoist engine 2 and tunnel steel tube, the support construction frame include The understructure frame 10 of superstructure frame 9, media layer damage frame 1 and understructure frame 10, the support construction frame is provided with enhancing The reinforcing column 11 of firm power, 1 front end of media layer damage frame are provided with hoist engine 2, and 1 rear end of media layer damage frame is provided with cunning Rail is equipped with dragging car 3 on the sliding rail, and the hoist engine 2 is connect with dragging car 3 by cable, fixed in the dragging car 3 There is semi-circular bracket 4, the bottom setting of the semi-circular bracket 4 is reduced the pulley of frictional force, 4 inside of semi-circular bracket It is provided with the carrying roller 8 for reducing 5 force of sliding friction of hose;It is provided with below the hose 5 for reducing 5 sliding friction of hose Roller, the hose 5 slides through semi-circular bracket 4, and described 5 one end of hose connects shield machine steel pipe 6, the shield machine steel Pipe 6 is installed on support construction top of the trellis, and the junction periphery of the hose 5 and shield machine steel pipe 6 is cased with reinforcing pipe 7, it is described plus Gu shield machine steel pipe 6 is fixed in 7 one end of pipe, the other end is fixed on the superstructure frame 9 of the support construction frame;The hose 5 The other end connects tunnel steel tube, and the tunnel steel tube is installed on tunnel, and the shield machine steel pipe 6 and the tunnel steel tube are horizontal In parallel, the support construction frame forward horizontal is mobile, and tunnel steel tube is fixed, realizes that the hose 5 pulls semi-circular bracket 4 With the horizontal movement backward of dragging car 3.
