Abstract
The utility model provides a separated pull-string pulley device, belonging to a device on a plastic film cover machine used for a saline crystal pool. The device is provided with an upper bracket, a lower bracket, and a plurality of pulleys are arranged through a plurality of shafts between the upper bracket and the lower bracket. Two ends of the upper bracket and the lower bracket are respectively fixed on two fixing rods. When in use of the pull-string pulley device, each string is respectively put on each pulley, displacing a common idle wheel and without mutual impact and also avoiding problems of the existing pulley device that the pull strings are mutually twisted and the separating is difficult. And then the smooth capability when in use is enhanced and a plastic film is convenient to be collected and extended.
Description
Technical field
The utility model provides a kind of device that the salt pan crystallizing pond is moulded the machine of covering with mat that is used for, especially stay cord pulley gear.
Background technology
In the salt industry production process, usually the machine of covering with mat of moulding to be set, before raining, plastics film is launched, cover with mat on the salt solution of crystallizing pond, behind the fine day plastics film is rolled.In the process of plastics film folding and unfolding, use the stay cord pulley gear.On the existing stay cord pulley gear upper and lower support is arranged; by rotating shaft single pulley is installed on the last lower bracket; many shared these pulleys of (having 7 usually) stay cord; occur through regular meeting that stay cord twines mutually, the problem of sub-argument difficulty; smoothness is poor; influence the folding and unfolding of plastics film, folder rope phenomenon also often occurs.Because unbalance stress, the bearing that is installed in the rotating shaft outside damages easily.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of split stay cord pulley gear, the smoothness when using to improve it.
The utility model is achieved in that a kind of split stay cord pulley gear, and it has upper bracket and lower bracket, by a plurality of axles a plurality of pulleys is installed between the upper and lower support, and the two ends of upper and lower support are separately fixed on two fixed links.
Adopt the stay cord pulley gear of said structure, during use, each root stay cord rides over respectively on each pulley, a no longer shared roller, be independent of each other to each other, the stay cord of having avoided occurring on the existing pulley gear twines mutually, the problem of sub-argument difficulty, has improved the smoothness when using, and is convenient to the folding and unfolding of plastics film.

Fig. 2 is the synoptic diagram of the utility model user mode.
Fig. 3 is the synoptic diagram of existing pulley device structure.
Embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and using method.
As shown in drawings, a kind of split stay cord pulley gear of the utility model, it has upper bracket (5) and lower bracket (4), by a plurality of axles (3) a plurality of pulleys (2) is installed between the upper and lower support, and the two ends of upper and lower support are separately fixed on two fixed links (1).
During use, this device is fixed on the ground by two fixed links.Each stay cord (6) is ridden over respectively on each pulley.One end of stay cord links to each other with plastics film, and the other end links to each other with total stay cord on the windlass.Launch in the process of plastics film, windlass pulling stay cord, stay cord drives plastics film and launches.In the process that stay cord moves, pulley sways.
Described pulley (2) is made by stupalith.Ceramic material surfaces is smooth, and corrosion resistance is strong, adapts to the salt pan environment.
The quantity of pulley is identical with the radical of stay cord.
Claims (2)
1. a split stay cord pulley gear is characterized in that, it has upper bracket (5) and lower bracket (4), by a plurality of axles (3) a plurality of pulleys (2) is installed between the upper and lower support, and the two ends of upper and lower support are separately fixed on two fixed links (1).
2. a kind of split stay cord pulley gear as claimed in claim 1 is characterized in that described pulley (2) is made by stupalith.
