Description

Quick dismounting device of current collector carbon brush frame

Technical Field

The invention relates to a quick dismounting device for a collector carbon brush holder, in particular to a quick dismounting device for a collector carbon brush holder of an overhead warehouse stacker of a tobacco industry logistics system.

Background

The automatic tobacco industry logistics system comprises a raw material overhead warehouse, an auxiliary material overhead warehouse, a finished product overhead warehouse and the like, and the roadway stacker is host equipment for completing the goods storing and taking functions of trays, boxes and the like in an automatic logistics stereoscopic warehouse, and has the advantages of saving land and manpower, being rapid and accurate in operation, improving storage efficiency, reducing storage and transportation cost and the like. And the system is networked with an upstream computer to control and forms a complete automatic logistics system together with other equipment. Is suitable for operation in narrow channels and limited spaces, and is ideal equipment for loading and unloading trays in overhead warehouses and workshops.

The stacker is powered by a safe sliding contact wire, the sliding contact wire is seven-core, a power supply is 380V three-phase four-wire system, a control wire is three-wire 220V power supply, and the sliding contact wire is a dustproof and splash-proof seven-wire sliding contact wire. Each stacker is provided with two parallel current collectors to ensure reliable contact with the trolley wire during high-speed operation of the stacker and ensure power supply quality. The current collector is a main device for picking up electric energy at the current collecting side in the power supply system of the stacker, and the electric energy is directly transmitted to the electric appliance through sliding contact between the carbon brush and the guide rail, so that mobile power supply of the system is realized.

The current collector used on the existing stacker is shown in fig. 1, and comprises a carbon brush holder and 14 carbon brushes 4, wherein the carbon brushes 4 are in sliding contact with a stacker guide rail; the carbon brush holder comprises a main support 8, wherein two rib plates 9 perpendicular to the rear side surface of the main support 8 are arranged on the rear side of the main support 8, so that a U-shaped groove extending along the vertical direction is formed on the rear side of the main support 8; the left side and the right side of the main bracket 8 are respectively connected with 7 bracket arms 5, 14 carbon brushes 4 are respectively arranged at the other ends of the 14 bracket arms 5, the 7 bracket arms 5 on each side are orderly arranged up and down, and the bracket arms 5 on the left side and the bracket arms 5 on the right side are symmetrically arranged left and right; the middle part of the support arm 5 extends forwards and is provided with a connecting plate 6, the connecting plate 6 is connected with a spring 7, and the other end of the spring 7 is connected with the carbon brush 4. The vertical section bar support of stacker electrical cabinet is located the U type inslot of main support 8 rear side to install the set screw on floor 9, the current collector passes through the section bar support of the tight stacker of set screw top, thereby realizes the installation of current collector on the stacker.

When the stacker runs for a long time and the plastic insulating layer of the current collector contacts with the insulating layer of the guide rail or the carbon brush is worn seriously or is worn unevenly, the current collector is considered to be worn, and the current collector needs to be replaced when the phenomenon occurs. When the current collector is replaced, fixing screws on the U-shaped grooves at the joint of the current collector and the profile bracket of the stacker electric cabinet are loosened, and then the carbon brushes at the left side and the right side of the current collector are pulled out of the guide rail grooves simultaneously, and then the U-shaped grooves of the current collector are moved downwards along the profile bracket. 14 carbon brushes simultaneously pull out the guide rail outwards and waste time and energy, and catch the guide rail easily, damage the guide rail backplate, lead to the carbon brush holder to warp even, the guide rail backplate lacks and has the power supply safety problem, buries down the potential safety hazard for the stacker operation.
