Description

The invention relates to underground construction and can be used in the erection of prefabricated tunnels.

The goal is ibeobten: and is to improve the performance of mounting obdeki.

1, FIG. 1 shows the device

for installation of prefabricated tunnel lining elements; FIG. 2 is a section A-A in FIG. 1, FIG. 3 — installation of elements into the lining ring.

A device for mounting prefabricated elements of a tunnel. Finishing contains two links 1 and 2 of the portal, rollers

3, on which link 1 and

2 when moving in directions

4, a template 5 mounted on a template 5 of a stand 6 with guides 7 rigidly attached to the link 1 of the portal, a system of jacks 8 connected to the template 5 and the link 1 of the portal Link 1 and 2 of the portal are interconnected by means of a hinge 9. For movement in the horizontal direction of the link 1 link 2 of the portal is equipped with a guide 10 with a slider 11, a nut 12 with a horizontal feed screw 13, a bracket 14 connected by a hinge 15 with a brake 16 of the support roller 3La with a bracket 14 mounted 17, the ends of which have a brake shoe 18 and a roller 19, installed can be moved along the protrusions

20 and slot 21 of the slider 11, One end of the slider 11 by the eye 22 is connected to the hinge of 9 links 1 and 2 of the portal, and the other end to the screw 13 of the horizontal feed. At the other end of which is the flywheel 23.

The device for mounting prefabricated tunnel lining works as follows:

In the initial transport position, the template 5 with the elements of the teamwork is omitted, and the entire device is moved on the rollers 3 along the guides 4 to the place of installation of the next finishing center.

In this case, the roller 19 is pressed against the slot 21 of the slide 11, and the brake pad 18 connected to it by the lever 17 does not prevent the device from moving. If necessary, adjust the position of the template 5 relative to the already mounted ring

the link 1 of the portal moves linearly along the rail guides 4, rotating the flywheel 23. Simultaneously with the beginning. rotation of the flywheel 23 is activated brake 16, securely holding the link. 2 portals on the guides 4. Linear movement of the link 1 of the portal occurs when the screw 13 moves the horizontal feed rotated in the nut 12 and is actuated by the flywheel 23, while the screw 13 is pivotally connected to the rear surface of the slide 11, which moves progressively in the guide 10. and moves the portal 15 pivotally connected by the slider 1 1 through the eyelet 22 .. In this case, the protrusions 20 of the slider 11 interact

with roller 19, brakes 16, Roller 19, rolling projections 20, rotates lever 17 in hinge 15 on bracket 14, thereby preloading brake pad 18 to the surface

Roller skating rink 3 links 2 portal.

After the adjustment of the position of the template 5 is completed, the last one and the prefabricated elements fixed on it are raised by the system of jacks 8 for mounting the next ring. Fixing

template 5 from lateral displacements for the period of installation; the lining is provided by the supports 6 and guides 7.

I

If it is necessary to change the direction of horizontal movement of the portal link 1 to the opposite, they change the direction of rotation of the flywheel 23.
