Description

The invention relates to transport equipment and can be used during loading and unloading operations at transshipment points of railway transport, in warehouses, in Kuzbvs, etc.

Known self-propelled bending conveyor containing a frame consisting of pivotally interconnected end and middle sections with driving wheels and equipped with driving mechanisms and mechanisms for rotating sections in the horizontal plane, flexible cargo tape, drive mechanism and belt tension and control mechanism [1].

However, this bending conveyor does not provide work in cramped conditions, its design is complicated by special devices to compensate for the length of the bending body during bending, and the flatness of the working surface during bending is not ensured.

The closest in technical essence and the achieved result to the invention is a movable curved plate conveyor, which includes a pair of rollers, bending around the traction body, and

the hinges located between sections with running wheels.

However, this conveyor provides a constant chain tension only at high angles of rotation of the sections.

The aim of the invention is to provide a constant length of the chain 'at small angles of rotation of the conveyor.

This goal is achieved by the fact that a pair of rollers is located on each section, which is equipped with an additional share of rollers, with both pairs of rollers placed along the edges of the section at a distance from the hinge axis defined by the formula

-2- £ <+ ·? G.,

where ¢, is the distance between the points of tangency of the pair of rollers of the previous and after ¹⁵ next sections, mm;

£ <— distance from the point of contact of the pair of rollers of the previous section to the axis of the hinge, mm;

- distance from hinge axis to point _{20 of} tangency of a pair of subsequent rollers

sections, mm.

In addition, one of the sections has a running drive wheel, the axis of which passes through the axis of the hinge.

FIG. 1 shows a movable curving plate conveyor, side view; in fig. 2 - the same, in a bent position, the plan; in fig. 3 is a view along arrow A in FIG. one; in fig. 4 - section B — B in FIG. one; in fig. 5 is a diagram of the position of the chain when bending the conveyor.

The movable bending plate conveyor consists of the head section 1 of the intermediate (linear) sections 2 and the end section 3. The sections are interconnected by hinges 4, which ensure the bends of the conveyors horizontally in the plane. The head section has a drive 5, consisting of an electric motor 6, a gearbox 7, transmitting rotation to the intermediate shaft 8, on which on the sliding key there is a double-sided clutch 9, engaged in engagement by a yoke 10 with a half coupling 11, transmitting a chain drive 12 rotation of the driving wheel 13 or the coupling half 14 , transmitting chain transmission 15 rotation of the sprocket 16. This asterisk drives the round-link chain 17 with plates 18 attached to it. Guides for the working branches carrying the load plates, and the lower ones - idle, serve as covers 1 9 sections. The housings 19 are made in plan with cuts, providing a continuous support plane of the plates when the sections are bent relative to the adjacent ones. Intermediate sections, as well as end sections, have pianoforte wheels 20 for moving along the transverse axis of the conveyor. The end section has a tension sprocket 21 for the initial tension of the chain. The direction of the chain during bending of the conveyor is provided by grooved rollers 22. The pairwise arrangement of the rollers 22 relative to the hinges ensures a constant total length of the chain branches when the sections rotate at any angle (see Figs. 2, 3).

The reference point of the running wheel 13 is located on the same vertical with the axis of rotation of the adjacent section to allow the head section to rotate when the conveyor moves.

Works proposed pipeline as follows.

When turning on the drive, rotation from it through gearbox 7 is transmitted to intermediate shaft 8, on which a double-sided clutch 9 sits on the sliding key. This clutch engages the holder 10 with the half coupling 11 and transfers the rotation of the running wheel 13 through the chain drive 12 wish4

mom direction. Then the traction chain is set in motion. For this purpose, the clutch 9 is engaged in engagement by the yoke 10 with the half coupling · 14, which, through a chain transmission, transmits rotation to the traction sprocket 18. The latter drives the round link chain 17 with the plates 18 attached to it.

For transportation of piece cargo in cramped conditions: in covered railway cars, in car bodies, from different parts of the warehouse without intermediate overloads, the proposed conveyor is installed when its movement is turned on, ensuring a small radius in any direction, anywhere on the conveyor, after which transportation of cargo in any direction along the axis of the conveyor. At the same time, the length of the working and idle branches remains constant, and the flatness of the working surface of the conveyor is ensured.
