A mounting and dismounting device for oil material rollers

Abstract

The invention relates to a mounting and dismounting device for oil material rollers. The device comprises a hydraulic transmission mechanism, a crank-slider transmission mechanism and a fixed connection mechanism. The hydraulic transmission mechanism comprises a double-acting oil cylinder (4), a piston rod (19) acting with the double-acting oil cylinder (4) cooperatively, an oil cylinder tail stock (2) and a hinge pin (3). The crank-slider transmission mechanism consists of a hydraulic rotating arm (7) equivalent to a crank, a connecting rod (11), a support shaft (5), a large retainer ring (6), an arc-shaped cover (17) arranged on the hydraulic rotating arm (7) via a rotating shaft (15), a clamp head (18) on the arc-shaped cover (17) and an insertion pin (10). The mechanism also employs the structure that the connecting rod (11) equivalent to a slider and a roller rear roller shaft sleeve (12) and a rear roller rubber sheath (13) and a fixing sleeve (23), which are arranged in front of and behind the connecting rod (11), are replaced by a roller adjusting shaft sleeve (28), a jackscrew (27), a nut (26) and a bolt (29). The device has the advantages of safe and stable structure, safe and accurate mounting and dismounting, high quality and efficiency and low cost.

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 the disassembly and assembly 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 transmis...

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.
