Description

The invention relates to the construction of tunnels and is intended for the erection of lining of prefabricated tunnel structures.

The aim of the invention is to simplify the construction of the block paver.

FIG. Figure 1 shows schematically a device for laying the elements of a tunnel tunnel when installed in a shield, a general view, in Fig. 2, view A in Fig. 1, in FIG. 3 - block stacker with gripper.

The block paver contains a turn - wheel 1 supported on roller supports 2 fixed in the shield casing 3. The roller supports 2 are configured to adjust their position in the radial direction. Reverse 1th drive 4 is connected to wheel 1 via an asterisk 5. Paired levers 6 with hinges 7 and 8 are mounted on wheel 1 at points of intersection of the wheel with the chord. The opposite ends of the levers 6 are joined with the hinges 9 and O with the grip 11. The levers 6 are filled with 1 -shaped, i.e. curved in vertical and horizontal planes with the possibility of creating a stable grip attachment structure. The locking pair of levers 12 one ends of their fixed on the wheel 1 by means of hinges I3 and 14, the opposite ends of these levers are connected by hinges 15 and 16 with the grip 11. The hydraulic cylinder 17 of the rotation of the levers 6 is hinged

on the swivel wheel. Geometric axes of articulated joints. 7, 8, 13, 14, and 18 are located in the same vertical plane perpendicular to the geometric axis of the shield. The hydraulic cylinder rod 17 is connected to the pair of bearing arms 6 by means of a hinge connection 19. The vertical distance between the axes of the hinges 7, 8, which are located on the chord of the circumference of the swivel wheel 1, and the geometric axes of the hinges 13, 14 of another pair of levers located perpendicular the vertical axis of the swivel wheel 1, equal to the distance between the axes of the hinge joints 9, 10 and 15, 6 of the levers 6 and 12 with the grip 11. On the wheel 1 in its upper part there is a counterweight 20 fixed, the mass of which is selected depending on the mass values uh 21 elements lining.

The operation of the block paver is carried out as follows.

Under the influence of the cylinder 17, the levers 6, together with the gripper 11, move in the radial direction, having carried out the necessary manipulations to grip the elements 21 and install them into the ring support. At the same time, the hinge system of levers attached to the wheel 1 and the grip 11 ensures a uniform predetermined speed of movement of the grip 11 with the support element 21. The presence of counter-load 20 reduces the power of the drive rotation of the wheel 1.
