Abstract

The invention relates to conveyor transport, in particular, to devices for transporting building materials, and allows to increase the reliability of operation of the device. The steel structures in the form of racks 1 are supported by guides made in the form of I-beams 2. On the upper shelves of the beams 2 are laid guides (G) 3, channel-shaped and directed with the open side up. Inside W 3 there are 4 bars, carrying a plate-roller infinitely closed draw chain 5. The latter is closed in a vertical plane and the W 6 guides rest on it. At the same time W 6 are made in the form of channel bars of larger W 3, open side to ZHZ with the possibility of their coverage. Rigid G 6 are connected to cargo-carrying cross-arms 7 with hooks for item 9. Traverse 7 with item 9 is placed on chain 5, which transports item 9 to the final destination. In this case, the bar 4 is the stroke limiter for the plates of the chain 5, which excludes its skew. 1 hp f-ly, 4 ill. i (o

WITH

The invention relates to conveyor transport, namely, devices for transporting building materials.

The purpose of the invention is to increase the reliability of the device.

FIG. 1 shows a chain conveyor, general view; in fig. 2 - the same, side view; in fig. 3 is a section A-A in FIG. 2; in fig. 4 — node 1 in FIG. 3

The chain conveyor includes a metal structure in the form of vertical truss-like Racks 1, located along parallel straight and installed I-beams 2, on which guided grooves 3 are laid, shaped like a channel bar and with the open side up and located inside the grooves 3 bars 4 square section, bearing plate-roller endlessly closed traction chain 5. The connection of the truss rack, I-bar, bar and bar between each other is rigid. The pull chain 5 is infinitely closed in a vertical plane, guiding channels 6, which are made in the form of channels of a larger cross-section than channel channels of channels 3, rest on it and are directed by the open side to the latter with the possibility of their coverage. The guide grooves 6 are rigidly connected to the load-carrying beams 7. At the beginning of the conveyor at the post of the installation of the cross bar there are two guides 8 of the figured profile to stabilize the course of the cross bar. There are two hooks on the traverse to illuminate the product 9, as well as a ring for gripping the traverse by a crane. Depending on the weight of the load, several cross-arms with different numbers of hooks may be used. The single chain branch 5 passes in the interval of the truss stand under the floor slab. It moves along a chute filled with oil, with a square guide rail.

Chain conveyor works as follows.

Heavy products 9, for example, concrete slabs, are suspended from the load-carrying cross bar 7 and the load-carrying crane is laid

the traverse with the products on the chain 5 at the post of the installation of the traverse where the figured guides 8 fix its exact direction. The conveyor is driven by a drive.

. feed (not shown). The chain 5, moving along the beam 4, transports the product 9 to the final point. The beam 4 is the limiter of the movement of the plates of the lamellar roller chain 5, since it excludes its bias. When rolling rollers on a bar 4 plates

0 interact with the bar so that the chain cannot accept any other motion impregnation except along the bar 4. The possibility of an open circuit is eliminated, since the supply drive has a safety coupling that activates in case of overload and stops the conveyor. Tensioning station for chain length adjustment.

The walls of the channel bars do not touch each other, since they move along a given figure 8 track. The specified direction eliminates the friction of the walls of one another.

Claims (2)

1. A chain conveyor comprising two infinitely closed traction chains supported by guides mounted on metal structures and freely mounted on the infinitely closed traction chains by supporting elements of load bearing beams, characterized in that , 4 aiming to increase the reliability of work, the guides are made in the form of I-beams with channels fixed on their upper shelves, with open sides pointing upwards and square bars mounted inside the channels, on which endlessly closed traction chains are supported. 2. A conveyor according to claim 1, characterized in that the supporting elements of the load carrying bar are made in the form of channel bars, each . of which is directed by the open side 0 to the channel, mounted on metal structures, is made of a larger cross section than the latter and installed with the possibility of its coverage. five Fig.z
