Special frock of frequency conversion roll table dismouting

Technical Field

The utility model belongs to the technical field of bar line roller way assembly, and particularly relates to a fixture special for disassembling and assembling a variable frequency roller way.

Background

After the steel unloading roller way under the rolling line cooling bed is used on line for a period of time, the roller body needs to be replaced in a large scale due to abrasion, the old roller body is pulled Ma Xiexia by hydraulic pressure after replacement, and a new roller body is installed again for reuse. At present, more three-jaw hydraulic puller is used on site, as the three jaws of the puller cannot be directly fixed under no pressure, the disassembly work is required to be completed by cooperation of multiple people, the three jaws and the ejector rod are fixed by two people, one person pulls Ma Jiaya, time and labor are wasted, and the disassembly speed is influenced. Meanwhile, the variable frequency roller way is large in weight, a large-sized pulling horse is needed, the variable frequency roller way or the pulling roller way Ma Chongliang is large, the labor intensity is high during disassembly, and safety accidents are caused once the pulling horse is fixed and pulled by hands.

The patent with the application number of CN201020648079 discloses a special lifting frame for roller way installation, which comprises a horizontal steel beam and a vertical steel beam, wherein the outer end of the horizontal steel beam is fixedly connected with a balancing weight, the lower end of the vertical steel beam is fixedly connected with a horizontal shaft sleeve, the horizontal shaft sleeve is in movable fit with a shaft arm of a bearing seat, a lifting lug is arranged on the horizontal steel beam, and the moment generated from the balancing weight to the lifting lug is equal to the moment generated from the shaft arm of the squeezing rubber roller and a sleeving point of the horizontal shaft sleeve. Although the hoisting technique is also used in this patent, the hoisting is for detaching or attaching the roller bed from or to the roller bed base, unlike this patent.

Disclosure of Invention

The utility model aims to provide a fixture special for disassembling and assembling a variable frequency roller way, which solves the problems in the prior art.

The technical scheme adopted for solving the technical problems is as follows: the utility model provides a special frock of frequency conversion roll table dismouting, includes the base, and walking wheel is installed at four angles in base bottom, and the base top is equipped with keeps off the platform, has placed the cardboard on keeping off the platform, and the welding has three riser on the cardboard, and the intermediate position welding of base one side has and immediately props, and it has the stull to prop the upper end welding immediately, and stull middle part welding has rings, and the one side welding that the base was connected immediately props has the trolley handle.

Further, be equipped with U type draw-in groove on the cardboard, U type draw-in groove one end is half circular, and the riser is around U type draw-in groove semicircle end evenly distributed, and the riser upper end is equipped with the grafting hole.

Further, the hanging ring is positioned on the vertical central line of the semicircular end of the U-shaped clamping groove.

The utility model has the following beneficial effects:

1. the lifting ring can be provided with the chain block, and the pulling horse is lifted through the chain block without manually lifting the heavy pulling horse, so that the labor intensity is reduced, and the potential safety hazard is eliminated.

2. The cardboard height can be designed according to roll body bottom height, only need with this device direct insertion to roll body bottom when using, convenient operation, dismantlement efficiency is high.

3. The hanging Kong Geila horse on the vertical plate provides a reliable hanging point, the hanging height of the pulling horse is improved, the pulling claw of the pulling horse is not required to be lifted manually and slightly, and the disassembly efficiency is further improved.

4. The walking wheels are arranged, and the detached roller body can be pulled away immediately after the walking wheels are detached, so that the labor intensity and the labor quantity are further reduced, and the working efficiency is improved.

5. By using the utility model, all operations can be easily completed by only one person, the working time is shortened to 0.5 hour from the original 2 hours, the manpower is saved, and the labor efficiency is improved.
