Maintenance device for chain buckle of double-chain conveying machine

Abstract

The invention relates to a maintenance device for a chain buckle of a double-chain conveying machine, and belongs to the field of material conveyance. The maintenance device consists of a positive pull buckle, a reverse pull buckle, a left screw rod, a right screw rod and a hexagon nut sleeve, wherein the end surfaces of the positive pull buckle and the revere pull buckle are respectively provided with two unfair screw holes, one end of the left screw rod is connected with the screw hole of the positive pull buckle, one end of the right screw rod is connected with the screw hole of the reverse pull buckle, and the two ends of the hexagon nut sleeve are respectively and movably connected with the other end of the left screw rod and the right screw rod. The maintenance device is arranged between two adjacent baffle strips of the chain buckle to be maintained on the double-chain conveying machine, the device can realize the matched use, the positive pull buckle and the reverse pull buckle are respectively used for clamping the two adjacent baffle strips arranged on the double-chain conveying machine, the two unfair screw holes are respectively formed in the end surfaces of the positive pull buckle and the reverse pull buckle, in addition, the screw rods are installed, the hexagon nut sleeve is used for connecting the two screw rods, the hexagon nut sleeve is regulated so that the distance between the two adjacent baffle strips conforms to the installing chain buckle pitch, and the installation is convenient.

Description

technical field [0001] The invention relates to a maintenance device for chain buckles of double chain conveyors. In particular, the invention relates to fast maintenance of chains on double chain conveyors, belonging to the field of material transportation. Background technique [0002] In the tobacco industry, conveyors are widely used, especially double-chain conveyors, that is, conveyors with two sets of chains symmetrically arranged left and right, such as the transportation of cigarette packs and boxes, which need to be transported from a low position to a high position, or from a It is convenient for stacking, etc., especially in the fields of tobacco logistics center, warehousing, rebaking and silk making. Conveyors are especially significant in reducing labor intensity and improving production efficiency. In short, in various modern In various industrial enterprises, the chain conveyor plays an increasingly important role in many loading and unloading machinery. It...

[0002] In the tobacco industry, conveyors are widely used, especially double-chain conveyors, that is, conveyors with two sets of chains symmetrically arranged left and right, such as the transportation of cigarette packs and boxes, which need to be transported from a low position to a high position, or from a It is convenient for stacking, etc., especially in the fields of tobacco logistics center, warehousing, rebaking and silk making. Conveyors are especially significant in reducing labor intensity and improving production efficiency. In short, in various modern In various industrial enterprises, the chain conveyor plays an increasingly important role in many loading and unloading machinery. It is no longer a simple material conveyor. It has become an organic unit in the production process of industrial enterprises. It is high and can hold heavy objects, but its shortcomings are heavy, fast wear, and difficult maintenance, especially the disconnection of the chain, the maintenance and replacement of the chain buckle, the installation and debugging of the chain, it is really very difficult for the maintenance personnel. very troublesome

[0003] The disconnection fault of the chain conveyor chain, the replacement of the chain buckle and the installation and debugging of the chain are common. If the chain conveyor does not have a tension wheel, if maintenance is required, the sprocket, motor, etc. must be disassembled. If the chain is broken The distance from the point is at a height of 3-5m, and manual repairs need to be assisted by elevators, so the labor intensity is high. Even if the repaired chain is repaired, it will be very laborious to install and debug, because the tension of the chain is much greater than that of the belt, and it must be overcome manually. The tension is strenuous

In the above-mentioned repairs, the most difficult thing is the replacement and installation of the chain buckle, especially the installation of the chain pin shaft. The concentricity between them can only be assembled within tens of microns, or even within ten microns. Therefore, tobacco processing enterprises have been studying how to improve the repair efficiency and reduce the difficulty of repair.
