 The invention relates to the field of ferrous metallurgy, specifically to equipment for the repair of mobile mixers.

The aim of the invention is to simplify the design, reduce metal consumption and increase reliability.

FIG. 1 shows a general view of the stand; in fig. 2 - the same view in the plate; FIG. 3 is a section A-A in FIG. 1 in FIG. 4 shows a section BB in FIG. one.

The stand contains four jacks 1, support rollers 2, drives 3 of rotation of rollers 2, frame A, pivotally fixed on support 5, tilt-pa;; .

Each roller 2 is mounted on a fork 9, hinged on frame 4, and connected to drive 3 by means of spindle 10. Fork 9 is supported on stop 1I and connected to hydraulic cylinder 12. The axis of rotation of fork 9 is positioned on the outer side relative to the plane passing through the lines 14 connecting the geometric centers of the cross section of the housing 15 of the mixer and the roller 2. On the frame 4 are mounted rails 16 and a roller 17 located between the bandages 18 of the housing 15.

On the side opposite to the frame tilting mechanism, there is a stationary stop 19.

The axis of rotation of each fork on the outer side with respect to the plane passing through the lines connecting the geometric centers of the sections of the mixer housing and the roller provides unloading of the forks by the hydraulic cylinder of rotation of the forks, increasing the reliability of the device, Otherwise It is possible that hydraulic rams may be lowered as a result of oil leaks and equipment failures, which may cause plugs to tip over and fall on the hull.

The stand works as follows

After the mixer stops at the stand, the carriages of 20 jacks 1 are pulled out, then the body 15 is raised by the brackets 21 and the chassis-mounted trolleys 22 are knocked out by the locomotive.

After turning the forks 9 to the working position (until it touches the 10

11) with jacks 1, the housing 15 is lowered onto the rollers 2, while the tires 18, with a gap, lash the roller 17. Then the end clamps 23 are disconnected and proceed to breaking the lining using a special machine (not shown).

In the process of breaking the position of the housing 15 is adjusted by rotating the rollers 2.

In order to remove the collapsed lining, the folding stop 7 is moved to the non-operating position by the hydraulic cylinder 8 and the hydraulic cylinders 6 frame 4 and the body 15 are inclined at an angle of 4-5. By rotating the body 15, the collapsed lining is removed to the duct 24 and transported by crane 25. Then return the frame 4 and the stop 7 to its original position.

If necessary, repeat the cycle of breaking and removing the lining, then install the end caps 23 and lay out a new lining. With the jacks 1, the housing 15 is raised to the extreme upper position, and the rollers 2 with the hydraulic cylinders 12 are moved to the non-operating position, after which the code carriages 22 are charged and the housing 15 is lowered.

Compared with similar equipment, the proposed stand has a simpler and less metal consuming design due to a reduction in the number of structural elements, excluding significant cantilever loads.

Claims (1)

Invention Formula A stand for repairing a mobile mixer, containing body lifts, track rollers and drive rollers, in contrast to the fact that, in order to simplify the design, reduce metal consumption and increase reliability, the rollers are mounted on forks that can be rotated in a vertical plane. bounded by stops and connected to rotational drives by means of spindles, wherein the axis of rotation of each fork is located on the outer side with respect to the plane passing through the lines connecting the geometric center section of the body of the mixer, and the ice rink. gz J9 1 / 4 IS FIG.
