Description

I

The invention relates to the mechanization of dismantling operations of a railway track, in particular, to the mechanization of operations on removal of rail link fastening elements, for example, mortgage bolts, from old-fashioned reinforced concrete sleepers when disassembling railway links.

At the same time, the device can be used in the assembly of parts of the railway track.

Fig, 1 shows the proposed device, a general view; Fig 2 is the same, top view; FIG. 3 is a section A-A in FIG. 2; FIG. 4 is a section BB in FIG. 3,

The device consists of a frame 1, made in the form of a portal, and movable on, carts 2 along the rails of the enclosing track 3, within which there are reinforced concrete sleepers 4 with bolts 5,

On the frame 1 there are mounted pump stations with a drive, a control panel (conventionally not shown) and two carriages 6 installed with the possibility of moving along the sleepers 4 along a roller guide 7 fixed on the bottom of the frame girder.

On the vertical guides 8 of the carriages 6, there are mounted in the vertical plane the plates 9 with hydraulic cylinders 10 mounted on frame 1 carrying the gripping bodies M, I and the hydraulic cylinders 12 turning the gripping bodies 11,

Gripping body 11 is made in the form of a glass with a window and a plate 13, us21271

eccentric on the glass eccentrically with the possibility of turning in a horizontal plane by a hydraulic cylinder 14, the inner surface of the glass and

5 the working surface, the eccentric, which come into contact with the fixing bolts, have threaded surfaces corresponding to the thread profile of the embedded bolt,

0 The device operates as follows.

Moving the device along the rails of the enclosing track 3 and the carriages 6 along the roller guides 7 of the device frame 5 of the axis of the gripping bodies (cups) 11 are aligned with the axes of the fixing bolts 5 of the concrete sleepers 4, the plates 9 are lowered into the lower position, while the threaded parts of the rods are fixed bolts 5 enter inside the gripping organs (glasses) 11,

By turning the plates 13 by hydraulic cylinders 14, clamping bolts are clamped by pressing plates 13 of the bolt section to the inner side wall of the glass, and by hydraulic cylinders 12, turning the gripping bodies and to the required angle 90, 30 After turning the bolt 5 using hydraulic cylinders 10, the plates 9 are raised to an upper position and the fixing bolts are removed from the sleeper 4,

After removing the bolts. 5. All injection mechanisms return to their original position, and the process is repeated.
