Description

The invention relates to devices for laying curbstones that can be used in the construction of roads and roads aipOB.

There are known devices of similar designation on the basis of earth-moving machines, including a rotary hydraulic grip and a platform for curbs. However, the well-known curbing does not finish the trench, does not lay down the concrete base under the curbs, and they are laid from one stone.

The purpose of the inventive is to eliminate the noted disadvantages.

This is achieved by connecting the stem of the side frame pneumatic mechanism to a gripper with a n npi vibrator: driven by a hydraulic cylinder, and a concrete hopper with a grip mounted on the trolley, the gripper made of hinged sections.

FIG. 1 shows the proposed device, general view; in fig. 2-pneumatic gripping with hydraulic jacks; in fig. 3 - pneumatic gripping for installation of 3-curb cages; on the bends of roads and sidewalks.

The device is mounted on the base of an excavator with a previously removed hand lever on the bucket. The device includes pneumatic gripping 1 with a length of six, eight stones, depending on their length, which is mounted on

trailer tech 2, on which is mounted a bunker 3 for concrete with a chuck 4 for adjusting the supply of concrete into the ditch for the base: under the curb. A skip lift 5 is installed on the bunker to raise the concrete; power station 6 for providing electric power to mechanisms (skip hoist, compressor, vibrators). Compressor 7 is installed to provide air for the main working unit. The pneumatic gripper 8 also has electrovibrators 8. A mounted trench digger 10 with a roller 11 is installed on the dozer spade 9 for digging a ditch under the base of curbstones and simultaneously sealing it. The depth of the ditch is governed by the lifting and lifting of the bulldozer shovel 9.

The gripper is a rigid clip of channel bars along the curb and a length of two, eight curb stones with vibrators. On the pneumatic grip, there are rubber flexible hoses 12 filled with air from the compressor, which serve to grip curbs.

The height of the gripper is driven by the hydraulic piston of the 3 gp hydraulic rams from the hydraulic system, and horizontally by the lodo-wigs by manually moving through the outlet arms of the console of the double tee 14.

For pneumatic gripping floods 1, the stones are mounted in horizontal and vertical planes, the latter is equipped with a fire detector, 15, and 16 leading devices.

For the curbing of the curb, the amnies from the factory to the place of installation use cassettes for six to eight stones along the length of the gripper and the width of the stones.

Straight sections of the road use straight rigid pneumatic gripping; on the turning sections of the roads, there is a hinged leumo gripper 17 for three or more stones.

The proposed device works as follows.

At first, the laying of the curb laying line is performed, the cord is pulled at a certain distance from the mounting axis to the length of the pulling air pick-up device. Then a ditch is dug along the cord with a ditch digger under the base of the board: with its simultaneous compaction with a roller.

The next step is to place the concrete into the base of the bin by adjusting the height of the base of the gate. In cassettes on vehicles brought curbstones and cassettes, unloaded and laid out the entire length of the laying of curbs.

After the concrete is placed in the base, the pneumatic grip is guided onto a cassette with squares and presses the top of curb stones with hydraulic jacks, the shock absorbing devices make it possible to level the top of the eight-stone with a single horizontal plane. Then filled; 1 Air Rubber flexible hoses from the compressor that press the side face of the curb to the rigid side of the pneumatic grip, thereby aligning the liner side of all the seized curb stones in one vertical plane. After the curbing and leveling of the curb stones 1, the system of hydraulic jacks is turned on and all the eight-stones are pulled out of the cassette and moved with the pneumatic platform but are mounted to the place of installation on the previously laid concrete base. With the help of a fixing and aiming device, pneumatic grip with curbstones is mounted on the mounting site and lowered.

0 pneumatic gripping with hydraulic jacks with curbstones to the desired level, followed by the inclusion of vibrators.

After the installation of the curbs in place by air release from the rubber grip of the pneumatic grip, the latter is released and the curb spreader is moved by the next cassette with curbstones, at the same time placing the concrete in the base for the next batch of six to eight curbstones

0 stones with the alignment of his low shcheberom.

Subject invention

1. A curbstone laying device including a trailer cart and pneumatic gripping mechanism with a hydraulic jack, characterized in that, in order to provide

the integrated mechanization of the installation, the jack of the hydraulic cylinder is connected to a gripper having a vibrator and driven by a hydraulic cylinder, and a concrete hopper with a slide valve is mounted on the trolley.

2. A device for laying curbstone on BC. 1, characterized in that, in order to enable laying on curved sections, the gripper is made of a composite of hinged sections.
