A port portal crane hoisting rope lubricant roller device

A port portal crane hoisting rope lubricant roller device is 2020 - 01 - 08 Yuan Zhou Hu Chengzhang soil expensive sun Lin Jiepu yuet abstract: this paper introduces a kind of based on port door crane wire rope of the development of roller lubrication device, this paper expounds the structure and working principle of the device, the device can reduce the labor intensity of door crane rope lubrication operation, reduce the operation security risks, improve the working efficiency. Key words: port door crane; Wire rope; Centralized lubrication; Roller wire rope as port crane hoisting mechanism important component, work environment is complex, susceptibility to corrosion, easy to wear and tear, so maintenance, maintenance of wire rope is very important, the most important of which is to ensure that wire rope good lubrication. 1 port portal crane hoisting rope lubrication status through the port door crane steel wire rope usage survey found that whether the door crane manufacturers, the wire rope lubrication are artificial daub, artificially with oil or grease direct daub on the steel wire rope, artificial daub workers work difficulty is big, widespread lubrication does not reach the designated position phenomenon, and pose a safety hazard. Two common ways of hoisting rope lubrication through consulting related literature material and port enterprise research, in addition to the way of artificial daub, the literature reports of wire rope lubrication pneumatic automatic lubricating device, the internal lubrication, special lubrication equipment lubrication and other several ways. The several ways of either on lubricating oil quality demand is high, or need special tubular cable, wire rope, or heavy structure and installation of trouble, in all the cost is high, and is not in conformity with the door crane structure [ 1] 。 Therefore, it is necessary to develop a simple and convenient, economic and reliable operation of wire rope lubrication device. 3 wire lubrication roller device design as the centralized lubrication system has been applied to door crane, boom hinge axis bearing, slewing ring wire rope pulley bearing, roller bearing parts, through the analysis of principle of wire rope roller structure studies have found that if the wire rope roller device redesign, with the help of a centralized lubrication system can through the roller to automatic lubrication of wire rope, wire rope a key is to eliminate its redesigned radial jump rope dynamic influence on supporting roller group, 2 it is to ensure that the wire rope around oil [effectively 2] ,( 3] 。 4 wire lubrication principle 4 roller device. 1 structure principle of the lubrication roller device for wire rope four rope door crane design, according to the diameter of wire rope in the middle of the roller open semicircle groove, semicircle groove processing four to six uniform spilled oil hole. Each wire rope using upper and lower two sets of roller, supporting roller through the guide card board between limit, keep the upper and lower rollers can be fixed spacing, and the upper and lower two sets of rollers constitute a movable whole. Set the card board slot roller, guide card board can move up and down in the card board slot. In this way both solve the radial jumping rope dynamic influence on supporting roller group, and ensure that wire rope around oil effectively. The specific structure is shown in figure 1. Fixed by means of threaded connections in the original roller position, wire rope through the wire rope between upper and lower roller. 4. 2 works when the wire rope need lubrication grease from centralized oil supply device through pipelines, ( Below) Within the supporting roller oil channel into ( Below) Roller lumen, and because of the rollers on both sides of the sealing ring seal, as the inner cavity is filled with grease, grease and oil hole overflow of rope groove for the steel wire rope groove lubrication. When the wire rope does not need lubrication, lubrication roller device only plays a role of bearing steel wire rope. 5 wire rope lubrication edge roller equipment for effective utilization of door crane centralized lubrication device and roller device, does not need to set up other devices, effectively realize the function of lubrication and bearing the double wire rope. The device is easy to operate, can reduce the labor intensity of door crane rope lubrication operation, reduce the operation security risks, improve the working efficiency. 6 in the wire rope is an important component of port lifting machinery, port of the bad production environment brought many challenges to the use of steel wire rope, so its maintenance lubrication is very important, so, we need to combine equipment structure characteristics, choose a suitable way of wire rope lubrication, ensure that wire rope good lubrication, prolong service life.
