Maintenance clamp of double-row roller chain

Abstract

The invention relates to a maintenance method and a maintenance clamp of a double-row roller chain, and belongs to the field of a material conveyor. The maintenance clamp of the double-row roller chain comprises a left handle, a right handle, a hinge shaft, an adjusting screw and an adjusting hand wheel, wherein the left handle and the right handle are respectively provided with a kidney-shaped hole, one end of the adjusting screw is movably connected with the adjusting hand wheel after respectively penetrating through the two kidney-shaped holes, and hinging structure connection is formed after the hinge shaft passes through a hinge hole with a counter bored hole at a clamp cheek part of the left handle and a hinge hole at a clamp cheek part of the right handle. When the maintenance clamp is used, a clamp nozzle part can be inserted between rollers of the double-row roller chain, a hinge plate needing to be maintained and rollers adjacent to a chain pin shaft can be clamped depending on arc parts, a clamp nozzle can be designed according to geometric parameters of the double-row roller chain, the tension between chains can be enlarged step by step through the fine adjustment of the adjusting hand wheel, the center distance between the rollers clamped by the arc parts of the clamp nozzle can be lessened step by step, a pitch which is suitable for installing the hinge plate and the chain pin shaft can be finally achieved, and thus the maintenance of the chains can be easy.

Description

technical field [0001] The invention relates to a double-row roller chain maintenance pliers, especially for quick maintenance of double-row roller chains on chain conveyors, such as quick maintenance or replacement of chain plates, chain pins and rollers, and is also applicable to Installation, commissioning and maintenance of chains on multi-row chain conveyors in the field of mechanical engineering. It belongs to the field of material conveyors. Background technique [0002] In the tobacco industry, such as the transportation of cigarette packs and boxes, it needs to be transported from a low position to a high position, or from A to B, which is conducive to stacking or shunting, etc. Most of them are widely used with conveyors or elevators. And chain conveyors are often used, mostly single-row chains or double-row chains, especially in the fields of tobacco logistics centers, warehousing, re-baking workshops, silk workshops and wrapping workshops. Conveyors can reduce l...

AI Technical Summary

Problems solved by technology

If the chain conveyor does not have a tensioning wheel, if maintenance is required, the sprocket, motor, etc. must be dismantled, which takes time and effort. Even if the chain is repaired, it is also very troublesome to install and debug, because the chain tension is large, and manual labor has to overcome this tension. very strenuous

In the above-mentioned repairs, the most difficult thing is the replacement and installation of the chain plate, chain pin and roller, especially the installation of the chain pin. The concentricity between the shaft and the round hole of the chain plate must be within tens of microns or even ten microns to complete the assembly. Therefore, tobacco processing enterprises have been studying how to improve the repair efficiency and reduce the difficulty of repair.
