Abstract

FIELD: motor road building technology. SUBSTANCE: according to method, slabs which have to be removed as last ones are anchored relative to ground base. Then, tipping ramp is brought under non-anchored slabs so that their protruding guide members are seated on guide members of ramps. After that, slabs are lifted and loaded into containers vertically standing on platform of carrying vehicle. As containers are being filled with removed slabs, filled containers are taken out and replaced with empty containers. Application of aforesaid method allows to simplify operations of removing and placing of road pavement slabs and to increase productivity. EFFECT: higher efficiency. 2 cl, 2 dwg

Description

 The invention relates to the field of construction of roads, in particular to the technology of removal and laying of road gauge from collapsible plates.

 There is a known method of stripping (a.s. USSR N 552382, E 01 C 23/03), which includes unlocking the hinges of the joints of the plates, installing the stacker at the end of the section in the direction of assembly, moving the equipment with the winch to its working position, laying the winch ropes on the upper blocks of the rack, passing the winch ropes through the half blocks of the stacking device, the winch pulling the ends of the coating links onto the pallets of the stacker, which moves forward as the coating is tightened, the hooks of the winch ropes are hooked by the following extreme hinges their plates and pulling them to the support on the beam of the rack, the assembly of packages of plates by successive pulling and fastening, while the stacker moves forward with a step equal to the length of two plates.

 The disadvantage of this method is the low productivity and high labor costs, since the basic operations are performed using manual labor.

 Closest to the claimed method is a method of removing and stacking rut hinged interconnected collapsible road plates, including lifting and stacking along the guides of the folding ramp plates in vertically standing containers on the stacker platform when the stacker moves in reverse (application N 93009501/03, published in bulletin No. 11, 04/20/95).

 A disadvantage of the known method is that when laying the plates in containers, the plates can move sideways from the folding ramp and a group of articulated plates can slide along the ground, which will lead to their folding into an "accordion" and jamming on the stacker platform.

 The basis of the invention is the task of simplifying the technology of removal and laying of road plates, which provides increased productivity and reduced labor intensity.

 The problem is solved in that when implementing the method of removing and laying rut hinged interconnected collapsible road slabs, including lifting and stacking slabs along the ramp rails in containers that stand vertically on the stacker platform when the stacker is moving in reverse, they are previously fixed relative to the slab ground , which are to be removed last, bring the folding ramp under the extreme, not fixed relative to the ground, plates, install them with protruding guides, Making a on the sides of the plates, an additional guide ramps for lifting and stacking containers. As the containers are filled with removed plates, they are replaced with empty containers.

 In FIG. 1 shows a General view of the stacker for implementing the inventive method, FIG. 2 - folding ramp.

 The stacker comprises a chassis 1, a platform 2, containers 3 mounted on it, a folding ramp 4 with guides 5 made in the form of live rolls, and additional guides 6. Collapsible plates 7 have protruding guides 8 on the side surfaces.

 Removing and laying rut hinged interconnected collapsible road plates are as follows.

 The stacker in reverse feeds to the extreme road slabs laid on the ground. Previously, or before removing the first plates, fixation is made relative to the soil of the plates, which will be removed from the ground last. The hinged ramp 4 is lowered down by the hydraulic cylinder (conventionally not shown on the graphic cylinder) and bring it under the plate 7, setting the latter by the protruding guides 8 on the additional guides 6 of the ramp 4. Moving in reverse, the stacker introduces the ramp 4 further under the plate 7 and it slides along guides 5, which are made in the form of a rolling table, and are fed into a container 3 vertically mounted on the platform 2. Due to the fact that the plates are pivotally connected to each other, they are folded into the bag when they fall into the container ner. As soon as the container is completely filled with plates, the container is disconnected from the platform and replaced with a new empty one and the process of removing laid road slabs to the ground continues. When approaching the last plate laid on the ground, it is unlocked relative to the ground and it also fits into the container.

Claims (2)

 1. The method of removing and stacking rut hinged interconnected collapsible road slabs, including lifting and stacking along the ramp rails of the slabs into containers vertically standing on the stacker platform when reversing the latter, characterized in that the slabs to be removed last are pre-fixed , relative to the ground, a folding ramp is brought under the extreme slabs of the laid coating not fixed to the ground and set by means of protruding guides, made s on the sides of plates, to guide additional folding ramps for lifting and stacking containers.  2. The method according to claim 1, characterized in that the containers filled with the removed plates are removed from the stacker and empty containers are installed in their place.
