Description

one

A machine for the manufacture of reinforced concrete liners is known, comprising a boring tool mounted on a chain conveyor and a device for excavating molded articles.

The purpose of the invention is to reduce metal consumption and increase productivity.

This is achieved by the fact that the machine is equipped with a drive base plate-pallet, on which the rigging equipment is freely supported, and the device for excavating the molded products is equipped with a mechanism for simultaneously stacking the products into a stack on the trolley, and the machine is made with a stacker of reinforcing cages onto the support plate - pallet, with a device for cleaning and lubricating the board while it is being moved, and with vibropressing mechanisms.

The drawing shows the proposed machine.

The machine includes a frame 1, a chain conveyor 2 with forms 3 mounted on its links, made without a bottom, a movable support plate 4 that performs the function of tsaddons and connected to the hydraulic rod, a reinforcement cage stacker 5, a device 6 for cleaning and lubricating forms, a vibrating table 7 with a drive, an apparatus 8 for forming the packings and a stacker 9.

Before switching on the conveyor 2 into the group of molds 3, supported freely on the plate 4, the reinforcement cages from the stacker 5 are stored. At the same time, the base plate 4 is in the right extreme position. When the conveyor is turned on, the forms with reinforcement cages slide along the base plate and move to the molding device 8, after which the conveyor stops and a concrete mix is fed into the forms located on the vibrating table 7, compacted by vibrating with simultaneous pressing. At the same time, the reinforcement cages are being laid in the next regular group of forms located on the drive base plate. The conveyor is then turned on and the molds with freshly molded articles are fed to the stacker 9, while the molded articles and reinforcing cages stacked in the next regular group of molds are held in the molds by a movable base plate, which is moved together with the molds by a hydraulic cylinder. The conveyor stops, the hydraulic cylinder returns the base plate to its original position, and the stacker pulls out (pulls out) the pulling out of the molds while laying them on the steam car 10. The reinforcement cages are in the forms above the vibrating table when the base plate returns to its original

the position slips along its upper plane, remaining in the forms.

Cleaning and lubrication of the molds is carried out by the device 6 during each working cycle; during one cycle of the machine operation, all technological operations are performed in parallel for the manufacture of reinforced concrete tacks with immediate dismantling and stacking of the group of tacks in a stack on a steam tram car. The number of heads in a group is determined by the width of the steam car. As the stacks are assembled, the trolley of a given height is replaced by an empty trolley.
