Soil pressure balance shield constructs machine (shield constructs machine for short) when the construction, every distance of advancing a section of jurisdiction width, just assembles the round section of jurisdiction, when assembling the section of jurisdiction, transports the section of jurisdiction from shield structure machine export to specific mounted position by the inside section of jurisdiction transport vechicle of shield structure machine, and in this transportation, the section of jurisdiction transport vechicle is longer through the route, consequently needs longer cable to follow the section of jurisdiction transport vechicle and remove, generally uses the cable slide-line to realize following of cable and remove.

A track that is used for section of jurisdiction transport vechicle to remove divide into high two roof beams and low two roof beams, and the track roof beam of low two roof beams is comparatively straight from the initiating terminal to the termination end, and the track roof beam of high two roof beams is a space roof beam from the initiating terminal to the termination end, and the extending direction of the track roof beam of high two roof beams is not from a straight line of initiating terminal to termination end promptly. In the cable sliding device, the track for the cable carrying trolley to move is a steel wire rope, the starting end of the steel wire rope is the same as the starting end of the high double-beam, the terminating end of the steel wire rope is the same as the terminating end of the high double-beam, but in order to adapt to the space radian of the high double-beam, the total length of the steel wire rope is larger than the linear distance between the starting end and the terminating end. In the in-service use process, the section of jurisdiction transport vechicle removes along high two roof beams, drives and takes the cable dolly to remove along wire rope, but the inventor discovery takes the cable dolly can appear moving not smooth problem, leads to the cable can't realize the removal of following to the section of jurisdiction transport vechicle, and then influences the normal construction of shield structure machine.

The inventor finds that the cable carrying trolley is prevented from moving due to serious sagging of the middle part of the steel wire rope caused by long length of the steel wire rope.

In view of the above problems, the present embodiment provides a wire rope flatting device for moving synchronously with a segment transport vehicle, as shown in fig. 1, which includes a flat wire member 10, the flat wire member 10 has a wire passing hole, through which a wire rope 5 for a cable sliding device passes, the flat wire member 10 is used for connecting with the segment transport vehicle, the flat wire member 10 may be circular, rectangular, or pie-shaped, plate-shaped, block-shaped, etc., and the flat wire member 10 may be a single component or a combined component. The wire through hole refers to a hole in a broad sense, and may be a complete circular hole, a square hole, or a hole with any cross-sectional shape, and of course, in some embodiments, the wire through hole may also be a through channel formed by combining different components, as long as the steel wire rope 5 can pass through the through channel.

In the work progress, connect flat line spare 10 on the section of jurisdiction transport vechicle, pass the wire hole with 5 one ends of wire rope to 5 that will hang originally are pulled up, and wire rope 5 under this state is the descending trend from the wire hole of crossing on the flat line spare 10 to 5 both ends of wire rope, and the wire rope 5 of each side all is more straight than drooping naturally. A plurality of cable-carrying trolleys are positioned on the steel wire rope 5 on one side of the flat wire member 10, along with the movement of the duct piece transport vehicle, the flat wire member 10 moves along the steel wire rope 5, the steel wire rope 5 is lifted to be straight, the cable-carrying trolleys also move on the relatively straight steel wire rope 5 along with the flat wire member 10, the passing is smooth, and the cable-carrying trolleys cannot be in motion interference with the flat wire member 10. Therefore, the wire rope 5 leveler of the embodiment of the application overcomes the problem that a cable-carrying trolley cannot pass smoothly due to the fact that the wire rope 5 of the cable sliding device sags, and ensures normal construction of the earth pressure balance shield machine.

As shown in fig. 1, the flat wire 10 includes a first wire supporting plate 1 and a second wire supporting plate 2, the wire passing hole includes a first wire passing hole 11 and a second wire passing hole 21, the first wire passing hole 11 is located on the first wire supporting plate 1, and the second wire passing hole 21 is located on the second wire supporting plate 2; first line hole 11 and the second line hole 21 of crossing are used for making wire rope 5 pass in proper order, and wherein, first prop between line board 1 and the second prop line board 2 can the certain distance of interval to make wire rope 5 be the straight state between first line board 1 and the second prop line board 2. For example, as shown in fig. 1, the flat wire member 10 may be a rectangular box structure to increase the stability of the whole structure of the flat wire member 10, wherein the first wire supporting plate 1 and the second wire supporting plate 2 are two opposite side walls of the box structure, respectively.
