Abstract

The utility model discloses a hydraulic oil cylinder. The hydraulic oil cylinder comprises a cylinder body, wherein a piston and a piston rod are arranged in the cylinder body; a cylinder head and a cylinder tail are respectively connected at the two ends of the cylinder body; one end of the cylinder head is connected with a hanging head; a piston rod position measurement device is fixed at one end of the piston rod; the measurement device and the piston rod are arranged correspondingly; a displacement sensor is arranged at one end of the cylinder tail; and the displacement sensor is connected with the piston. Because the displacement sensor is fixed at one end of the cylinder tail of the hydraulic oil cylinder, the displacement sensor measures the displacement amount of the piston rod precisely by sensing a magnetic ring fixed on the piston and transmits the measured signal to a control device; simultaneously, because the piston rod position measurement device is fixed at one end of the piston rod, a numerical value cannot be read directly by the displacement sensor in an installing and debugging stage, at the moment, the numerical value can be read directly on the measurement device; and therefore, the installation and debugging work is simplified, the hydraulic oil cylinder has convenience in operation, high flexibility, and popularization and using values.

Description

Hydraulic jack

Technical field

The utility model relates to the hydraulic jack field, particularly relates to a kind of hydraulic jack that is used for solar electrical energy generation.

Background technique

Hydraulic jack with hydraulic pressure can change mechanical energy into, the do straight reciprocating motion hydraulic actuator of (or oscillating motion).When realizing to-and-fro motion with it, can remove speed reducer from, and not have drive gap, therefore motion steadily is used widely in the hydraulic system of various machineries.

Yet existing oil hydraulic cylinder generally can not be measured the movement travel of piston rod, and the movement travel of piston rod is fixed, and flexibility is relatively poor.

The model utility content

The technical problem that the utility model 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 utility model 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 utility model; 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; 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 utility model, said slide bar is fixedly connected with piston rod through connecting rod.

In preferred embodiment of the utility model, said scale bar two ends are connected with cylinder head and cylinder tail respectively through fixed block.

In preferred embodiment of the utility model, said piston is provided with magnet ring, and said displacement transducer is electrically connected with magnet ring.

The beneficial effect of the utility model is: the utility model hydraulic jack 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.

Fig. 1 is the perspective view of the utility model hydraulic jack one preferred embodiment;

The mark of each parts is following in the accompanying drawing: 1, displacement transducer, 2, the cylinder tail, 3, piston, 4, piston rod, 5, cylinder body, 6, piston rod, 7, slide bar, 8, scale bar, 9, cylinder head, 10, connecting rod, 11, hang head, 12, fixed block, 13, dunnage.

Embodiment

Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.

See also Fig. 1, the utility model is embodiment comprise:

A kind of hydraulic jack comprises cylinder body 5, is provided with piston 3 and piston rod 6 in the said cylinder body 5; The cylinder body two ends are connected with cylinder head 9 and cylinder tail 2 respectively; Said cylinder head 9 one ends are connected with and hang 11, and said piston rod 6 one ends are fixed with the piston rod position measuring device, said measuring device and piston rod 6 corresponding settings; Said cylinder tail 2 one ends are fixed with displacement transducer 1, and said displacement transducer 1 is connected with piston 3.

Said measuring device comprises slide bar 7, slip ring 4 and scale bar 8; Said slide bar 7 is fixedly connected with piston rod 6; Said slide bar 7 ends are fixed with slip ring 4, and said scale bar 8 is fixed on cylinder body 5 one sides, and said slip ring 4 is slidingly connected with scale bar 8; Through seesawing of piston rod 6, can drive slide bar 7 and seesaw simultaneously.

Said slide bar 7 is fixedly connected with piston rod 6 through connecting rod 10, is fixed with dunnage 13 on the said cylinder head 9, and said dunnage 13 and slide bar 7 are slidingly connected, and are used to support slide bar 7, connect more firm, convenient disassembly.

Said scale bar 8 two ends are connected with cylinder head 9 and cylinder tail 2 respectively through fixed block 12, the slip ring 4 corresponding settings on scale bar 8 and the slide bar 7.
