[0030] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0031] like Figure 1 As shown, this embodiment provides a device for conveying double pipe installation in a shield, including a movable frame 1, and multiple sets of moving wheels 18 are symmetrically provided on both sides of the lower end of the frame, and the moving wheels 18 are configured with rails 23 installed in the ground 19 of the tunnel body 21. A rotatably connected mounting column 16 is provided on the frame 1, and the mounting column 16 is driven by a mounting column driving device. An inclined plate 4 for mounting the pipe body is provided on at least one side of the mounting column 16, and a rubber pad 5 is installed on the inclined plate to prevent the pipe body from being bumped. A binding belt 11 for binding the pipe body is connected to the inclined plate 4, and the binding belt 11 is connected to a winding roller 13 installed at the upper end of the mounting column, and the winding roller 13 is driven by a winding roller driving device. This device integrates the functions of transportation and gantry crane. When the pipeline needs to be installed, the binding belt can be directly loosened after installation, which not only saves construction costs but also improves construction efficiency.

[0032] In this embodiment, a pipe body can be provided on one side of the mounting column 16, and a counterweight block can be provided on the other side for balance. Alternatively, two inclined plates 4 can be symmetrically provided on both sides of the mounting column 16 and two pipe bodies 10 can be installed on the inclined plates. The specific design can be determined according to the needs of the site. This embodiment takes the latter case as an example for explanation.

[0033] In this embodiment, in order to improve the efficiency of construction, a proximity switch 8 for detecting whether the pipeline body is installed in place is provided on both sides of the installation column 16 corresponding to the inclined plate 4. The proximity switch is connected to the installation column 16 through an adjustment mechanism, wherein the access switch 8 is used to control the action of the winding roller drive device. When the access switch 8 detects that the pipeline body is in place, the motor of the winding roller drive device is controlled to stop rotating, and the binding belt stops rising. The adjustment mechanism includes an adjustment tube 12 installed on the installation column 16 and a plug rod 7 inserted in the adjustment tube. The adjustment tube 12 is screwed with a limit screw 9, and the limit screw 9 and the plug rod 7 are in contact. The plug rod 7 is locked by the limit screw 9. The proximity switch 8 is installed at the outer end of the plug rod. By setting the adjustment mechanism, according to different sizes of pipeline bodies, by adjusting the position of the plug rod in the adjustment tube, it is determined that the position when the middle of the upper and lower heights of the pipeline body and the proximity switch are in contact is the position after the adjustment is completed, thereby adapting to different sizes of pipeline bodies. The weight of pipeline bodies of different sizes is different, and the weight of the pipeline body is balanced by adjusting the position of the sliding counterweight on the sliding rod.

[0034] In this embodiment, the winding roller driving device includes a winding turbine 14 installed on the winding roller 13, a winding worm 15 is engaged on the winding turbine 14, a traverse motor 17 is connected to the winding worm 15, and the traverse motor 17 is fixedly installed on the mounting column 16. The traverse motor 17 drives the winding worm 15 to rotate, the rotation of the winding worm drives the winding worm wheel 14 to rotate, the rotation of the winding worm wheel 14 drives the winding roller 13 to rotate, and the winding roller 13 rotates to reel the binding belt 11. When the pipeline body and the proximity switch are close, the traverse motor 17 automatically stops.

[0035] In this embodiment, when only one side of the pipeline body needs to be installed, a limit switch 6 is installed on the side of the inclined plate 4. The limit switch 6 located on the side of the inclined plate is in contact with the inclined plate 4, and the limit switch 6 can limit the rotation angle of the installation column. The binding belt 11 in this embodiment can be a rope or other belt-like components that can be wound.

[0036] In this embodiment, the mounting column driving device includes a deflection turbine 3, a deflection worm 2 is engaged on the deflection turbine 3, a dual-axis motor 20 is connected to the deflection worm 2, and two output shafts of the dual-axis motor 20 are respectively connected to the two deflection worms. By setting the mounting column driving device, the rotation of the mounting column can be driven.

[0037] This embodiment also provides a working method using the above-mentioned device for conveying double-pipe installation in a shield, comprising the following steps:

[0038] S1. The initial position of the device is outside the tunnel. First, the binding belt 11 is removed from the winding roller 13, and then spread outward and laid flat on the ground;

[0039] S2, then hoist or roll the pipeline body 10 onto the binding belt;

[0040] S3, then fix the outer end of the binding belt 11 to the winding roller 13 by means of fixing bolts, start the winding roller driving device, and the winding roller rotates to wind up the binding belt 11. When the pipeline body 10 and the proximity switch 6 are close, the winding roller driving device automatically stops. At this time, the height of the pipeline body is exactly the installation height of the pipeline body in the tunnel;

[0041] S4, then use the electric locomotive to drive the frame to move and then drive the device and the pipeline body to move into the tunnel;

[0042] S5. After moving to the position, since the installation height has been set in advance, the pipeline body is directly installed and fixed by the installation bracket, and then the binding belt 11 is removed, and then the locomotive drives the device to move outward and exit.
