Abstract
The utility model relates to a flexible dragline with high performance. The outer surface of a wire rope core and the inner surface of a shell flexible pipe are respectively provided with one layer of composite plastic. The material can use polyethylene with high density as the main body material, and then can be mixed with proper molybdenum disulphide. Compared with a dragline which is only coated with one layer of composite plastic at the outer surface of a wire rope core, the transmission efficiency can be improved by 12-15% by the flexible dragline. Compared with a traditional flexible dragline, the performance of the flexible dragline of the utility model can be improved a lot.
Description
The utility model belongs to the soft drag-line that mechanical transmission is used.
Soft drag-line has become mechanical transmission, particularly one of mechanically operated important way on automobile.May be because it is relatively simple for structure, people be few to the research report that improves its structure and further its performance of raising.Claimant of the present utility model is on the basis of test of many times research, providing a kind of is 92101559 and 92204063 described soft drag-lines as application number, and the maximum difference of this soft drag-line and existing soft drag-line is the surface applied one deck composite plastic at Steel cord.Practice proves, and the transmission efficiency of this soft drag-line has improved a lot (see application number for details be 92101559 patent application specification) than the soft drag-line of traditional usefulness.But through continuing experimental study, we think can also continue to improve structure, further improves its transmission efficiency.
The purpose of this utility model provides a kind of transmission efficiency height, soft drag-line that performance is good, easy to manufacture.
The utility model is realized its purpose as follows: the shell flexible pipe internal surface at soft drag-line adds one deck composite plastic, and the thickness of plastics is advisable with 0.2～0.5m/m.Plastics can be to be material of main part with the high density polyethylene (HDPE), mix an amount of molybdenum disulfide.
Soft drag-line of the present utility model and application number are the soft drag-line of 92101559 and 92204063 described structures, and test is under the same conditions compared, and load pulling force transmission efficiency can improve 12%～15%, and quality of product is higher.
Embodiment further specifies the utility model below in conjunction with accompanying drawing:
Fig. 1 is the soft stayed structure schematic representation that composite plastic layer is arranged at Steel cord surface and shell flexible pipe internal surface.
Outer surface at Steel cord 1 has composite plastic coating 2, and its thickness can be 0.2～0.6m/m; The shell flexible pipe is formed by three layers, and outermost surface is a plastic protective layer 5, and the centre is the metal body 4 that is made of the steel wire of reeling, and also has one deck composite plastic 3 at the internal surface of metal body 4, and its thickness can be 0.2～0.5m/m.The plastic layer 3 of the external surface coating 2 of Steel cord and metal body 4 internal surfaces can be a material of main part with high density polyethylene (HDPE) all, infiltrates an amount of molybdenum disulfide and makes.In producing and using, not only whole soft drag-line can adopt as above said structure, if the internal surface at the end-fitting part shell of drag-line also adds one deck composite plastic, can significantly reduce the friction between Steel cord and the joint shell, obviously increase the working life of soft drag-line.
Claims (1)
1, a kind of soft drag-line, the outer surface coating one deck composite plastic at Steel cord is characterized in that also adding one deck composite plastic at the internal surface of shell, and thickness is advisable with 0.2～0.5m/m.
