RU144548U1 - Trolley Conveyor - Google Patents

Abstract

A trolley conveyor containing a supporting metal structure, on which rolling guides are mounted with the possibility of moving trolleys along them, interconnected by intermediate elements, characterized in that the trolleys are equipped with rotors - secondary elements of a linear asynchronous motor (LAD), which move the trolleys under the action of a magnetic field, generated by the stator - the primary element of LAD.

Description

The utility model relates to conveyor transport, namely, to cart conveyors, and can be used in all industries.

Known vertically closed cart conveyor [1] with tipping carts, consisting of a towing element with attached carts, moving along the guide ways of the supporting structure of the conveyor, drive and tensioning device.

The disadvantage of this conveyor is the relative complexity of the design, which does not provide a constant speed of the traction chain and imposes restrictions on the speed of its movement due to intense wear and additional dynamic loads that occur at high speeds. In addition, the large metal production and the complexity of maintenance of the structure due to the presence of a large number of hinges in a closed circuit, requiring regular inspection and lubrication.

Closest to the proposed technical solution is a cart conveyor [2], equipped with a ferromagnetic strip mounted on the cart with the ability to move in a plane perpendicular to the plane of the guide path, and the flexible traction body is made in the form of articulated ferromagnetic elements installed with the possibility of interaction with a magnetofriction drive and the electromagnet is rigidly fixed to a flexible traction body and is located with the possibility of coupling with the ferromagnetic strip of the load-carrying bogies, while the force of adhesion of the electromagnet with the ferromagnetic strip is greater than the force of adhesion of the ferromagnetic elements of the traction body with a magnetofriction drive.

The disadvantage of this conveyor is the complexity of the design, the significant cost of the drive devices, as well as the complexity of manufacturing a traction body of a special design.

The objective of the utility model is to develop the design of a cart conveyor with minimal material consumption, adjustable speed and increased reliability of cargo transportation.

This task is achieved by the fact that the utility model has a supporting metal structure on which rolling guides are mounted with the possibility of moving trolleys along them interconnected by intermediate elements, while the trolleys are equipped with rotors - secondary elements of a linear asynchronous motor (LAD) that move the trolleys under the action magnetic field generated by the stator - the primary element of LAD.

When implementing the utility model, a technical result can be obtained consisting in the possibility of moving the load in the forward and reverse direction and changing the speed of movement in a wide range, in addition, in reducing the metal consumption and simplifying the design by eliminating the tension station, mechanical drive, drive traction chain, which leads to a decrease in dynamic loads.

Figure 1 shows a General view of the conveyor, side view; figure 2 is the same, a top view; figure 3 shows the conveyor trolley, side view (view A in figure 1); figure 4. shown is a conveyor carriage on guides, front view (section BB in FIG. 1).

The trolley conveyor includes a supporting metal structure 1 (Figs. 1, 2), on which the rolling guides 2 (Figs. 1, 2, 3 and 4) and stators 3 (Fig. 2) are fixed, the primary stationary elements of the LAD, which are a magnetic circuit with winding, receiving energy from the network. Rotors 4 (Figs. 3, 4) - secondary movable LAD elements are made in the form of a sheet (strip) of non-magnetic metal or a complex package of adjacent strips of non-magnetic and ferromagnetic metal. Through the insulating gasket, the rotors 4 are fixed on the bogies 5 (Fig.1, 2, 3 and 4), which are interconnected using intermediate elements 6 (Fig.3, 4).

Cart conveyor operates as follows. When voltage is applied to the windings of the stator 3 (FIG. 2) LAD, an electric current appears, a traveling magnetic field is generated, which, as a result of magnetic induction, interacts with the rotors 4 (FIGS. 3, 4) of LAD and causes a longitudinal shear force moving the trolley located above it 5 (figures 1, 2, 3 and 4) along the guides of rolling 2 (figures 1, 2, 3 and 4). Received the movement of the trolley 5 through the intermediate elements 6 (3, 4) carries along the rest of the trolley, which in turn receive a driving force, passing over the stator LAD.

The technical and economic advantage of the claimed utility model lies in the fact that the use of a linear asynchronous electric motor allows to simplify the transmission of traction, increase the efficiency and reliability of the conveyor, and also makes it possible to smoothly control the speed of the conveyor over a wide range, the possibility of stopping the conveyor without the use of additional braking devices , the ability to set the stepwise movement of the bogies, in addition, allows for the transportation of goods along the route second length in the forward and reverse direction.
