Abstract

A DEVICE FOR TRAILING, DOWNLOADING AND UNLOADING A WAGONETTE, containing a transport mechanism, a door lift and a carriage pusher mounted on an autonomously moving self-propelled frame, characterized in that, in order to increase the production of equipment, to automate the operation of the device, a transport will be a part of the form and you will be a form. located along the front of the dryer and equipped along its entire length with rail tracks.

Description

The invention relates to the industry of building materials, in particular, to the production of coarse ceramics, for example clay brick and drainage pipes.

The purpose of the invention is to increase the productivity of the equipment and automate the operation of the device.

FIG. 1 shows a device for transporting and loading trolleys into tunnel dryers; fig 2 is the same for unloading tunnel dryers; in fig. 3 is a view A of FIG. 1; in FIG. A — view B in FIG. 2

A device for transporting and loading cars into technological units and from them consists of a closed rhythmically stationary cargo-carrying conveyor 1 arranged along the front of the tunnel, for example a chain conveyor, whose two infinite parallel traction chains JIO are equipped with transverse paired rails 2, forming rail tracks for installation on them moving cars 3, which are loaded from the initial position 4, equipped with a stationary pusher 5. On the self-propelled frame 6 mounted door lift 7 and telescopic, for example hydraulic, pusher of trolleys 8.

The self-propelled frame 6 for passing it along the train of trolleys on the load-carrying conveyor 1 has an L-shaped form, both racks of which are equipped with wheels 9 supported on horizontally mounted rail 10 and 11 along the tunnel front, and the pusher 8 is mounted on the frame 6 also with the possibility of the passage of the frame 6 along the train trolleys on the conveyor 1.

The device for loading the trolleys works as follows.

The stationary shop pusher 5 feeds onto the load-carrying conveyor 1 the first trolley 3 located on the track of the starting position 4. The conveyor 1 moves one step equal to the distance between the adjacent rail tracks 2 with a speed ensuring the combination of the role of the conveyor 1 and the ways of the starting position 4 immediately after turning off the drive conveyor 1 (for example, 0.1-0.2 m / s) after stopping conveyor 1 to it

the next trolley 3 rolls in, etc.

Regardless of the movements of the load-carrying conveyor 1, the self-propelled frame 6 pulls up to the next tunnel to be loaded and lifts its door using the door lift 7. After docking, the rail of the load-carrying conveyor 1 and the load tunnel push the trolley 8 into the tunnel. With the return to the initial position, the pusher 8 lifts the doors 7 and lowers the door, after which the self-propelled frame 6 pulls up to the next loaded tunnel.

The loading of the trolleys from the carrying conveyor alternates with its loading at the initial position.

A device for transporting and unloading trolleys (Figs. 1, 2 and 4) contains a rhythmically operating load-carrying conveyor 1, similar to that used in a loading device, equipped with rails 2 for mounting movable trolleys 3 on them, a rail track 12 for moving along it along the drying front tunnels of the undercarriage 13, equipped with a lift of the doors 7. In addition, the undercarriage of the trolley 13 is equipped with a carriage 14 moving perpendicular to the axis of the carrying conveyor 14. A carriage 14 is mounted on the carriage 14 From a vertically mounted extension in a vertical direction, for example, from a telescopic column 15 and horizontally fixed at the lower end of the column 15, pusher pins 16 with a snub 17 for unloading trolleys 3. On the boom pusher 16 there is a protrusion provided with an abutment 18 for moving the trolleys 3. Position 19 removing the unloaded trolleys 3 installed the stationary pusher 20.

A device for unloading trolleys from drying tunnels works in a similar way to a device for loading, but with a different sequence of operations. Chassis trolley 13 pulls up to the unloading tunnel and lift doors 7 raises the door. At the same time, the carrying pallets 1 are moved in such a way that opposite the unloaded tunnel it is located empty (ba3.

cantna) Then (FIG. 4), the extendable column 15 lowers the push rod into the lower position

16 and carriage 14 leads capture

17 rods of the pusher 16 under the frame of the trolley 3 for its gripping and subsequent pushing it out of the tunnel by the carriage 14.

Having installed the trolley in the transport position, the telescopic column 15 lowers the rod of the pusher 16 until the gripper 17 is released from contact with the frame of the trolley and the carriage 14 pulls the rod of the pusher 16 out of the trolley zone by moving along the trolley 13. Next, the column 15 lifts the rod 16 to its upper position, which does not impede the passage of the undercarriage 13 over the train of the trolleys 3 to the conveyor 1. Then the undercarriage goes to the next tunnel to be unloaded.

At position 19 of the removal of the trolleys from the load-carrying conveyor 1, the stationary shop pusher 20 takes them to the shop ways (see Fig. 2). 5 As the positions on the conveyor 1 are released, it is filled with the next 1 trolleys.

The device for loading and unloading trolleys provides the possibility of flexible and operative interaction of component mechanisms, reduces unproductive time losses by combining operations, eliminating idle runs of mechanisms.

All this provides an increase in the productivity of equipment 20 and of transport and loading operations and creates conditions for automation and its transfer to operation in non-operation mode.
