A dismantling device for an oil roll

Abstract

The present invention relates to a mounting and dismounting device for an oil material roller. The mounting and dismounting device is characterized by comprising hydraulic transmission, crank transmission and fixed connection mechanisms; the hydraulic transmission mechanism comprises a double-acting cylinder (4), a piston rod (19) cooperating with the double-acting cylinder (4) to act, a cylinder tailstock (2) and a hinge pin (3); and the crank transmission mechanism comprises a hydraulic rotating arm (7), a roller adjusting shaft sleeve (12), a supporting shaft (5), a large check ring (6), an arc-shaped cover (17), a chuck (18), a bolt (10), a jackscrew (11), nuts (13) and studs (23), and besides, a structure that a connecting rod (27) is arranged at the upper part of the hydraulic rotating arm (7) to replace the roller adjusting shaft sleeve (12), the jackscrew (11), nuts (13) and studs (23) is adopted by the mechanism. The mounting and dismounting device has the characteristics of safe and stable structure, safety and accuracy in mounting and dismounting, high quality and efficiency, low cost and the like.

Description

technical field [0001] The invention relates to the technical field of tools or devices for removing and installing oil rolls of oil flaking mechanical equipment such as hydraulic crushers, in particular to a dismantling device for oil rolls. Background technique [0002] As we all know, there are many types of oil flaking machinery and equipment such as hydraulic crushers at home and abroad, and the most used crushers or flaking machines include double-roll and double-roll flaking machines. The former is inconvenient to adjust due to the small pressure between the rolls, and the effect of crushing or flaking is not good; the latter has a large unit processing capacity due to the high pressure between the rolls and the high speed. The existing various crushers or flaking machines generally have low output, poor crushing or flaking effect, unstable hydraulic system, especially many faults, and easy wear of the transmission belt (especially vertical transmission). It is diffi...

AI Technical Summary

Problems solved by technology

The former is inconvenient to adjust due to the small pressure between the rolls, and the effect of crushing or flaking is not good; the latter has a large unit processing capacity due to the high pressure between the rolls and high speed.

The existing various crushers or flaking machines generally have low output, poor crushing or flaking effect, unstable hydraulic system, especially many faults, and easy wear of the transmission belt (especially vertical transmission). It is difficult to adjust the gap between machine rolls, prone to roll collision, rolls are prone to peeling and edge loss, the service life of the rolls is short, and parts are easily damaged (such as bearings are easily damaged), and other deficiencies, so it is necessary to frequently replace and disassemble the oil rolls of the flaking machine , Moreover, the volume and weight of the oil roll are large, and it is very difficult to replace and disassemble

At present, the amount of maintenance and installation of the oil roll of the billet machine at home and abroad is very large. In addition, the volume and weight of the oil roll are large, difficult to replace and disassemble, and the safety, accuracy, quality, and efficiency of disassembly are low, and the cost is high. At the present stage, electric hoists or chain hoists are mostly used for hoisting and dismantling, and there are few special dismantling and installation tools or devices for oil rolls. These have become urgent problems to be solved in the maintenance and installation of oil crushing or flaking machinery and equipment.
