Maintenance-free pedrail tension station

From;    Author:Stand originally

Pedrail needs to often check Zhang Jin to spend, with slow down pedrail wear away. Traditional Zhang Jin pattern is the combination of crock of butter Zhang Jin and high strenth bedspring more. Maintain strength of multifarious, labor big, and the butter that discharge carries on his shoulder or back is opposite easily external environment causes pollution. Improve model tension station of maintenance-free pedrail hydraulic pressure, use charge a powerful person of fluid discharge carry on one's shoulder automatically, overall can undertake automatically full fluid to tension station in regular job process, whole process simple, save labour, prevented the leak outside hydraulic pressure oil, realized the maintenance-free of pedrail tension station truly. This kind of device compares the labor intensity that reduced a worker greatly with the photograph of bedspring tension station previously, improved the service life of pedrail.

The structure of pedrail tension station after improving is shown 1 times like the graph, the principle is shown 2 times like the graph, basically carry on his shoulder or back by discharge full fluid L of a powerful person, accumulator 2, glue is in charge of 3 and 5, contact 4, Zhang Jin crock 6, directive wheel assembly 7 wait for composition.



L of a powerful person of carry on one's shoulder of discharge full fluid receives next pitch of hopper crock. A powerful person of carry on one's shoulder of discharge full fluid is comprised by one one-way sequence valve and ball valve, when tension station pressure is inferior, those who carry a powerful person of carry on one's shoulder of discharge full fluid is one-way fill hydraulic pressure oil to its, and when tension station pressure is higher, the hydraulic pressure of relief valve discharge that carries a powerful person of carry on one's shoulder of discharge full fluid is oily, arrive since accumulator amid store the action of fluid and amortize. Working principle is as follows: Hopper of? of ignoranting  Pi dominates set up an electric circuit of a powerful person, add up to hopper hold back to live a few minutes, make hydraulic pressure oil enters piece of close crock and accumulator through one-way a powerful person, drive piece of close crock forward shift makes pedrail Zhang Jin, a powerful person of carry on one's shoulder of discharge full fluid and accumulator implement pair of systems protect pressure, maintain pedrail Zhang Jin, give Zhang Jin pressure through can measuring crimp head. The process is here medium as oil of the discharge inside a powerful person, pedrail is corresponding and flagging, should add up to hopper hold back to live a few minutes to be able to be opposite in time again only at this moment pedrail Zhang Jin. Deflate, unused when, control soft string through be being measured accessarily randomly, measure tension station pressure dot and answer oil to measure press a dot to connect can.
