Abstract
An oil cylinder with a synchronous displacement sensor comprises a main cylinder body (1), a piston rod (2), a magnetostriction displacement sensor (3) installed on the piston rod, an auxiliary oil cylinder (6) and the synchronous displacement sensor (4) installed on the piston rod of the auxiliary oil cylinder. A cylinder body of the auxiliary oil cylinder (6) is fixedly connected with the main cylinder body (1), a connection rod (5) is fixed at the position of the position rod (2) outside the main cylinder body (1), and the other end of the connection rod (5) is connected with the piston rod of the auxiliary oil cylinder (6). When the built-in magnetostriction displacement sensor of the oil cylinder breaks down, the oil cylinder can operate normally by switching signals in a shortest time without stopping production for maintenance.
Description
Technical field
The utility model relates to the hydraulic jack field, specifically, relates to a kind of oil cylinder with the synchronous shift sensor.
Background technique
Mostly that adopts in the oil cylinder of the band displacement transducer that uses at present is magnetostrictive displacement sensor; And this sensor mostly is installed in the piston rod of various oil cylinders; Through stretching of piston rod, drive magnet ring and move forward and backward, directly measure the traveled distance value of the oil cylinder piston throw of lever.In this case, after built-in sensor breaks down and damages, must be with the oil cylinder pressure release, could processes sensor or magnet ring after taking apart.Will cause the handling failure time long like this, generally need more than 3 ~ 5 hours.If fault just occurs in the flowing water process, will influence rhythm of production, cause productivity to descend, fault time phenomenon such as overlength.
Summary of the invention
The purpose of the utility model provides a kind of oil cylinder with the synchronous shift sensor, when magnetostrictive displacement sensor breaks down, need not the maintenance that stops production, and can guarantee that equipment normally moves at shortest time intra signal.
The technological scheme that realizes above-mentioned purpose is: a kind of oil cylinder with the synchronous shift sensor; Comprise Master cylinder body, piston rod and be installed in the magnetostrictive displacement sensor on the piston rod; Also comprise auxiliary cylinder and be installed in the synchronous shift sensor on the auxiliary cylinder piston rod; The cylinder body of auxiliary cylinder is fixedly connected with Master cylinder body, is positioned at the outer piston rod position of Master cylinder body and is fixed with connecting rod, and the other end of this connecting rod is connected with the piston rod of auxiliary cylinder.
Further, piston rod one end of auxiliary cylinder is enclosed within on the connecting rod.
After adopting technique scheme; Set up auxiliary cylinder and be installed in the synchronous shift sensor on the auxiliary cylinder piston rod, the piston rod position Master cylinder body outside is passed through connecting rod and is connected with the piston rod of auxiliary cylinder, and the piston rod of such two oil cylinders can same moved further; The synchronous shift sensor on the auxiliary cylinder piston rod and the magnetostrictive displacement sensor of Master cylinder body piston rod form the dual fail-safe structure; Two sensors can arbitrarily switch, and when wherein a sensor breaks down, need not the maintenance that stops production; Can guarantee that equipment normally moves at shortest time intra signal.
