Abstract
The invention discloses a hydrocylinder, which includes a cylinder body, wherein a piston and a piston rod are arranged in the cylinder body; a cylinder head and a cylinder tail are connected with the two ends of the cylinder body respectively; a lifting head is connected with one end of the cylinder head; a piston rod position measurement device is fixed at one end of the piston rod; the measurement device corresponds to the piston rod; and a displacement sensor is fixed at one end of the cylinder tail and connected with the piston. According to the invention, the displacement sensor is fixed at one end of the cylinder tail, and can be used for accurately measuring the displacement of the piston rod through inducting a magnet ring on the piston and sending measured signals to a control device; and meanwhile, as the piston rod position measurement device is fixed at one end of the piston rod, at the installation and debugging stage, numerical values cannot be directly read out through the displacement sensor, and can be read out on the measurement device, the installation and debugging work is simplified, and the hydrocylinder is convenient to operate and has better flexibility as well as popularization and application values.

The technical problem that the present invention mainly solves provide a kind of simple in structure, flexibility good, can intuitively read the displacement amount of piston rod and the hydraulic jack of working position effectively.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of hydraulic jack is provided, comprises cylinder body; Be provided with piston and piston rod in the said cylinder body, the cylinder body two ends are connected with cylinder head and cylinder tail respectively, and said cylinder head one end is connected with and hangs head; Said piston rod one end is fixed with the piston rod position measuring device; The corresponding setting of said measuring device with piston rod, said cylinder tail one end is fixed with displacement transducer, and said displacement transducer is connected with piston.
In preferred embodiment of the present invention, said measuring device comprises slide bar, slip ring and scale bar, and said slide bar is fixedly connected with piston rod, and said slide bar end is fixed with slip ring, and said scale bar is fixed on cylinder body one side, and said slip ring and scale bar are slidingly connected.
In preferred embodiment of the present invention, said slide bar is fixedly connected with piston rod through connecting rod.
In preferred embodiment of the present invention, said scale bar two ends are connected with cylinder head and cylinder tail respectively through fixed block.
In preferred embodiment of the present invention, said piston is provided with magnet ring, and said displacement transducer is electrically connected with magnet ring.
The invention has the beneficial effects as follows: hydraulic jack of the present invention is owing to be fixed with displacement transducer at cylinder tail one end, and displacement transducer comes the accurately displacement amount of measurement piston rod through the magnet ring that induction is fixed on the piston, and the signal that records is sent to control gear; Simultaneously, because piston rod one end is fixed with the piston rod position measuring device, in the Installation and Debugging stage; Displacement transducer can't directly be read numerical value; This moment is reading numerical values on measuring device directly, has simplified installation and debugging work, and is easy to operate; Flexibility is better, has popularizing value.
