Description

J

The invention relates to mechanical engineering, in particular to devices for transportation, and can be used, in conveyors for fastening to chains, which do not have any special links, to different types of cargo-carrying elements.

Chains to plate conveyors are known, in which the link chain link you are lugged with protrusions that are placed in the holes of the plate flooring and are secured with spring pins l.

However, in these conveyors is impossible. Use standard chains and this attachment is possible only in plate conveyors.

Chains to lamellar conveyors are also known, in which the clamps for fastening the load-carrying elements are made in the form of brackets hinged on the internal chain link 2 J.

In these chains, the attachment devices of the working bodies are used only for plate conveyors. They cannot be used, for example, for

combined horizontal-vertical conveyors, as well as, if necessary, the chain rollers roll along guides due to the overlapping of one side of the chain with plates or U-shaped brackets ..

The aim of the invention is to eliminate these drawbacks, as well as reducing the labor intensity and improving the quality in the manufacture and repair of the conveyor chain without disassembling it.

This goal is achieved in that the modes are made in the form of two brackets placed one inside the other, one of the xusors covers one inner and one outer plate, and the brackets are interconnected by a locking connection, for example, with a pin placed in coaxial holes, with openings. staples are located.

On f g. 1 - a general view of a part of a chain, side view; in fig. 2 - the same plan view; in fig. 3 - section A-A of FIG. one; on . FIG. 4 - BAB FIG. 2j nafig. 5.6 Filling outer spring bracket; in fig. 7 - fastening of the working bodies to. Chains with braces with locking lugs; in fig. 8, 9, 10 - fastening of two chains with a simplified internal brace without a second bend; in fig. 11-18 are examples of clamp assembly on a chain. The conveyor chain includes external 1 and internal 2 zbenev plates, rollers 3 and rollers 4, a clip for fastening the load-carrying elements, which consists of the inner bracket 5 and the external bracket 6, .k ..- Н -К,. with KIT t-1 t l. tirr which are connected with a clutch 7. When using a tightly roller chain as a traction, the inner bracket 5 has a width that is 1 extremely smaller than the distance between the inner plates 2 (for the possibility of rotation inside the link) and is made with notches for rollers 4 in the middle parts. The recess is made with a gap that does not prevent the free rotation of the rollers 4 of the chain. The inner bracket 5 fits into the outer bracket 6 and is connected with the last locking element 7 passing through the holes in the brackets. . From the longitudinal displacement, the clamp is fixed by the outer bracket 6, the movement of which is limited by the heads of the peeking rollers 3 of the chain. Outer bracket 6 Along the width Made with a small gap between the heads of the rollers 3. The outer bracket 6 is rigid (Fig. 3) or spring (Fig. 5 and b). Bolts, pins, etc. can be used as locking elements. or part of the working body fixed to the chain. The assembly of the clamp on the chain is carried out as follows: the inner bracket 5 (Fig. 11-18) is inserted between the plastics of the 2-internal chain link and the rollers 4, and after a break of 90 ° it enters the spacer with the notches into the space between the rollers 4 of the chain and then presses plates 2 internal link. The inner locking bracket 5 (Fig. 3) is installed outside the chain, enters the outer bracket 6 and presses against the outer plates 1 between the heads of the chain rollers 3 (Fig. 1). An interlocking element 7 is inserted into the offset holes 6 of the outer 6 and inner 5 staples. Staples 5 and 6 are assembled on a chain with minimal clearances ensuring the mobility of the chain. The clamps are disassembled in an orderly manner. The fastening of the working bodies can be made to any of the brackets 5, 6 n closing element 7, which can also be part of the working body. When used as traction stub-roller chains, working with "" large loads or not requiring .. twelve time roggers, for fixing the workers of the body to the chain, they can be used separately: internal igur brackets with fixed arms of FIG. -7} .--: When used in pairs and a working body, it may be necessary. uts- a grooved inner figurna bracket, without a second bend, for fastening both on one and on two chains (Fig. 8.9, 10). Claims of the invention The conveyor chain, including internal and external, plates, rollers, oliki and clamps for fastening load-bearing alloys, differs so that, in order to reduce the complexity and improve the quality of removal and repair of the chain without disassembling, clamps made in VyD two located in one another, brackets, one of which covers the inner joint and one outer plate, with the brackets connected between the aamka connection, for example, a pin placed in coaxial holes with which the brackets are made. 2. The container chain according to claim 1, characterized in that, in order to use the chain as a traction, the inner bracket is made with notches for the rollers in its middle part. 3. The conveyor chain according to p. 1, O TL I h a r i s with the fact that, with a reduction in the time-consuming assembly and disassembly of the clamps, the outer bracket is made of elastic material.
