Description

The present invention relates to auxiliary devices of conveyors, in particular to devices for lubricating chains, and can be used to automatically lubricate the hinges of the traction chain of an overhead conveyor.

Closest to the claimed invention is a "Device for lubricating bearings of carriages of the traction chain", patent SU No. 2306461, F16C 33/66, F16N 7/32, B65G 45/02.

This device for lubricating the bearings of carriages of the traction chain includes a track with the carriages located on it, in which the bearings are mounted, a lubricant supply system consisting of a reservoir with heat-resistant lubricant and a lubricant supply pipe with nozzles, as well as an air preparation unit. On the track, which is an I-beam, a base is installed with a distribution plate fixed to it. On the distribution plate there is a limit switch connected with an electro-pneumatic valve, and two vertically arranged levers. The levers are fixed to the distribution plate by means of screws with the possibility of free rolling relative to these screws. One of the levers in the place of attachment with a screw is made longer and curved with a rod located in its upper part. The pipeline on the distribution plate forks to supply lubricant to each of the nozzles. The jets are enclosed in rollers and placed at the bottom of the levers.

The disadvantages of the known device are:

- the inability to lubricate the hinges of the traction chain, which entails a low service life of the chain;

- the complexity of the design.

The claimed technical solution is aimed at increasing the service life of the traction chain and simplifying the design.

The technical result is achieved by the fact that the device for automatic lubrication of the hinges of the traction chain of the overhead conveyor, comprising an I-track with the carriages located on it, a base with a distribution plate, an air preparation unit, a lubricant supply system consisting of a lubricant reservoir and a lubricant supply pipe material branching on a distribution plate for supplying lubricant to each of the nozzles, and a limit switch associated with an electro-pneumatic valve m, contains a carrier plate located on both sides of the route, on which two base plates are mounted with side stabilizers with chain stabilizers installed on them, the base is fixed to one of the base plates and the end switch and the spring-loaded axis connected to it are mounted on it with brackets a roller interacting with the inner link of the traction chain.

In FIG. 1 shows a device for automatic lubrication of hinges of the traction chain of an overhead conveyor, general view.

In FIG. 2 is a section AA in FIG. one.

In FIG. 3 is a section BB in FIG. one.

In FIG. 4 is a view B in FIG. one.

In FIG. 5 is a section GG in FIG. one.

The device for automatic lubrication of the hinges of the traction chain of the overhead conveyor consists of route 1 with carriages, air preparation unit 2 and a lubrication system. Moreover, for the implementation of the lubrication process, the device contains a spring-loaded axis 3 with a roller 4 fixed on it and a limit switch 5 connected to the electro-pneumatic valve 6.

Route 1 is an I-beam, and each carriage consists of left and right half-carriages 7, located on both sides of the route 1. Chain links are connected to the carriages, interconnected by hinges 8. On the route 1, on its both sides, there is a carrier plate 9, on which, by means of two sidewalls 10, support plates 11 are mounted with chain stabilizers 12 mounted on them. The stabilizers 12, mounted on both sides of the chain, eliminate lateral oscillation of the chain. On one of the base plates 11, a base 13 is fixed with a distribution plate 14 mounted on it by means of an arm, on which an electro-pneumatic valve 6 is mounted.

A spring-loaded axis 3 with a roller 4 and a limit switch 5 are also fixed on the base 13 by means of brackets. In this case, the limit switch 5 is connected to the electro-pneumatic valve 6 and the spring-loaded axis 3. The spring-loaded axis 3 is configured to interact on one side through the roller 4 with the internal link 15 traction chain, on the other hand, with a limit switch 5.

The lubricant supply system includes a reservoir 16 with lubricant and a lubricant supply pipe 17 with nozzles 18. A lubricant supply pipe 17 branches at the outlet of the distribution plate 14 for supplying lubricant to each of the nozzles 18.

The working area of the lubrication system is a roller 4 of a spring-loaded axis 3, chain stabilizers 12 and nozzles 18 through which lubricant is supplied to the chain links.

A device for automatic lubrication of the hinges of the traction chain of an overhead conveyor works as follows.

The device is installed along a chain having continuous horizontal movement. The contact of the device with the chain occurs through the roller 4, mounted on a spring-loaded axis 3 and having the possibility of rotation.

When the traction chain moves, the roller 4, held by the inner link 15 of the traction chain, under the action of the spring 19 falls into the gap between the two outer chain links 20, located one above the other.

The limit switch 5 is automatically activated, giving the command to open the electro-pneumatic valve 6, after which the lubricant supply channels open. Lubricant under air pressure through a branched pipeline 17 through the nozzles 18 is simultaneously fed to the hinges 8 of the traction chain. In the process of further movement of the chain, the roller 4 of the spring-loaded axis 3 runs into the inner link 15 of the traction chain, thereby returning to its original position. In this case, the limit switch 5 is turned off, as a result of which the electro-pneumatic valve 6 is closed and the supply of lubricant is stopped. With further movement of the traction chain, the joints of the following links are lubricated, and the cycle repeats.

Using the proposed technical solution allows you to:

1. Increase the service life of the traction chain

- due to the lubrication of the hinges of the traction chain due to the presence of a spring-loaded axis with a roller interacting on the one hand through the roller with the internal link of the traction chain, on the other hand, with a limit switch;

- due to the presence of stabilizers, eliminating lateral vibration of the circuit.

2. Simplify the design by reducing the number of components.
