Description

Vertical warehouse chain lifting device for rubber tire

Technical Field

The utility model belongs to tire production facility field says in detail a rubber tire is with vertical storehouse chain hoisting device.

Background

As is well known, in order to reduce cost, improve production efficiency and reduce personnel consumption, the current rubber tire manufacturing industry gradually uses a large number of three-dimensional storehouses as automated handling and storage equipment. The three-dimensional garage is similar to a basic framework of a mechanical parking three-dimensional garage with special equipment on the same row. The hoisting device is mainly referred to GBT3811 crane design specification, and the roller is rotated by a motor, and the lifting motion of the lift truck is driven by 2 steel wire ropes.

The working grade of a hoisting mechanism of the three-dimensional garage hoisting device is selected from M5, the diameter of a steel wire rope is 16mm, the diameter of a pulley is selected from 350mm, and the basic requirement of 20 times of the diameter of the steel wire rope specified by GBT3811 can be met. However, in the production process, due to high production efficiency, frequent lifting of the crane and high lifting load, the working grade of the lifting mechanism should be selected to be a higher M8 grade. The phenomenon causes serious abrasion and fatigue, more broken wires and even fracture of the steel wire rope at the contact section of the steel wire rope and the pulley under the action of frequent alternating load. The steel wire rope needs to be replaced every 6 months on average, so that the workload and the maintenance cost of maintenance personnel are increased; and a large potential safety hazard exists in the operation process.

To solve this problem, it is necessary to increase the diameter of the sheave and reduce wear fatigue due to the frequent alternating load. According to GBT17907 general safety requirements for mechanical parking equipment, the diameter of the pulley is more than 40 times of the diameter of the steel wire rope, and accordingly, the diameter of the pulley is required to be more than 640. For reasons of space, the diameter of the pulleys at the respective diverting locations cannot be made larger.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a rubber tire is with standing storehouse chain hoisting device has practiced thrift cost of maintenance, guarantees operation and system safety operation.

The utility model provides a technical scheme that its technical problem adopted is: a vertical garage chain lifting device for rubber tires is provided with a left upright post and a right upright post, a cross beam is fixed between the upper ends of the left upright post and the right upright post, and is characterized in that a steel wire rope reel is installed on the lower portion of the left upright post through a bracket, a rotating shaft of the steel wire rope reel is driven by a motor, a first steel wire rope and a second steel wire rope are wound on the steel wire rope reel, a second chain wheel and a third chain wheel are respectively installed on the cross beam at the upper ends of the left upright post and the right upright post, a first guide wheel is installed at the left end of the cross beam, a lifting vehicle is arranged between the left upright post and the right upright post, the upper end of the first steel wire rope is connected with one end of the first chain through a snap ring after bypassing the first guide wheel, the lower end of the first chain is fixed with the right end of the lifting vehicle after the first chain is meshed with the third chain wheel, the upper end of the second steel wire rope is connected with one end of the second chain through the snap ring, the lower end of the second chain is fixed with the left end of the lifting vehicle after the second chain is meshed with the second chain, the length of the first chain is less than that of the first steel wire rope, and the length of the second chain is less than that of the second steel wire rope.

The beneficial effects of the utility model are that, simple structure can guarantee under the effect of frequent alternating load, the light sustainable safe use of chain wearing and tearing has remain former cylinder again and has driven wire rope and practice thrift space, compact structure, and the elevating speed keeps unanimous with original, guarantees that production efficiency does not reduce. The workload of maintenance personnel is reduced, the maintenance cost is saved, and the operation and the safe operation of the system are ensured.
