(54) CART FOR LOADING AND UNLOADING FRAMES WITH CERAMIC PRODUCTS

This invention relates to devices for transporting, loading, and unloading kera-. hardware products in factories equipped with chamber dryers and can be changed for the transportation of any piece goods transported on the framework.

Carts for transporting, loading, and unloading ceramic products operating in cramped conditions are known, such as, for example, a device which, by shifting the platform to the right and left relative to the chassis, can bypass obstacles in the path of 1J.

The disadvantage of this device is that the displacement of the load platform only unilaterally reduces the transport dimension of the cargo being carried and is not acceptable for loading and unloading frames with ceramic products.

Closest to the present invention, there is a device for inserting a two-deck trolley into the loading area of an automatic stacker containing a chassis part, a turntable mounted on the vertical axis of the device.

mechanisms for turning and lifting the turntable 2.

The proposed device allows loading with a turn around the vertical axis of a trolley with shelf supports carrying frames with ceramic products. - The disadvantages of this are that the devices are unable to reduce the envelope when. an increase in the capacity of the shelf trolley due to an increase in the pitch of the transported load, as well as the falling of the frames with ceramic products when the ends of the frames are hooked on the walls of the inlet chamber, which occur when this load is laborious to clear and significantly reduce the scrap rate.

The purpose of the invention is the behavior of labor productivity.

Claims (2)

This goal is achieved by the fact that the load-carrying device of the trolley is made in the form of a hinged parallelogram consisting of two lifting-swiveling frames and a hinge of associated cargo forks with mounted on them pivot pivots for multi-stage installation of frames with ceramic products, with a scrap the load-carrying device is mounted on a turntable with the possibility of lifting. FIG. 1 shows the device, a general view; in fig. 2 - the same, front view; in fig. 3 - the same in terms of. The device consists of a chassis 1, on which a turntable 2 is mounted, driven by a hydraulic cylinder 3, a lifting frame 4 connected to the turntable through a lifting hydraulic cylinder 5 and a turning frame 6 connected to the lifting frame by hinges 7 and the running gear by hinge 8 .Frames 4 and 6, bearing on themselves forks 9, connected to them with hinges} 0. On the cargo forks 9, pivot bearing pins 11 are installed on which the frames 12c are mounted with ceramic products. Lifting-swiveling 4 and 6 and cargo forks 9 with turning points 11 are made in the form of a hinged parallelogram and together form a load-carrying device. The proposed trolley works as follows. A carriage loaded with frames with ceramic products moves from the automatic machine, and, having approached the chamber dryer, turns the frames 4 and 6 by means of the hydraulic cylinder 3 through a turning circle 2 at a predetermined angle limited by the course of the hydraulic circuit. The frames 4 and 6, having turned, bring the forks 9 closer together with their simultaneous displacement along the axis of movement of the trolley, thereby the frames 12 with the ceramic products mounted on the rotary marks 11, turn at the same angle as the turntable, reducing thus, the overall size of the bag with LO to L) but the width of the cart. The cart is prepared for entry into the chamber and enters it with the maximum gaps between the ends of the frames and the walls of the chamber. Having approached the place of unloading, the cart stops, frames 4 and 6 return to the initial floor with the help of hydrocyles 3 and turn circle 2 and install frames 12 with 2-piece ceramic products. in the original position. The hydraulic cylinder 5 lowers the frames 4 and 6 with the forks 9 to the lowest position, and the frames with ceramic products are shifted from the fork 9 to the support shoulders of the dryer. The unloaded trolley returns to the storage unit to receive the next package of frames and enters the cargo forks 9 under the accumulated frames with ceramic products, after which frames 4 and 6 are raised with hydraulic cylinder 5, taking the frame from the shelves of the accumulator to the support points 11 fork 9. The cycle repeats. Application of the proposed trolley For loading and unloading frames with ceramic products into the drying chambers allows increasing labor productivity in the least reliable and non-mechanized sector of labor, reducing the scrap rate. Claims trolley for loading and loading frames with ceramic products, comprising a chassis carrying a turntable with a load bearing device including frames with shelf racks, characterized in that the workstations are made in the form of a hinge parallelogram consisting of two lifting-swiveling frames and cargo forks hinged with them; c) swivel feet mounted on them for bulk installation of frames with ceramic products; The device is simulated on a turntable with the possibility of lifting.
