Abstract
The utility model discloses a stroke-adjustable hydraulic oil cylinder for engineering. The stroke-adjustable hydraulic oil cylinder comprises a cylinder body, a front cylinder cover, a rear cylinder cover, a piston rod and a piston, wherein the piston rod and the piston are arranged in the cylinder body, the piston is arranged at the tail end of the piston rod, and a transmission plate is arranged at the front end of the piston rod and connected with equipment to be transmitted. The stroke-adjustable hydraulic oil cylinder for engineering is characterized in that the front end of the piston rod is provided with an adjusting section extending outwards, the adjusting section is provided with an adjusting thread and a locking nut matched with the adjusting thread, and the transmission plate is screwed on the adjusting section. By arranging the adjusting section and the locking nut and adjusting the position of the transmission plate, the locking nut locks, requirements for different transmission connection positions are met, and with no need to change internal structure of the cylinder body, the stroke-adjustable hydraulic oil cylinder is convenient and flexible to use.
Description
Technical field
The utility model relates to a kind of hydraulic jack, particularly a kind of range-adjustable engineering hydraulic jack.
Background technique
Oil hydraulic cylinder with hydraulic energy change mechanical energy into, the do straight reciprocating motion hydraulic actuator of (or oscillating motion).Its simple in structure, reliable operation.When realizing to-and-fro motion with it, can remove speed reducer from, and not have drive gap, therefore motion steadily is widely used in the hydraulic system of various machineries.Oil hydraulic cylinder is divided into piston type, plunger type, swing type and telescopic by structure type, wherein uses at most with piston-type hydraulic cylinder.
Piston-type hydraulic cylinder is comprised of cylinder barrel, piston, piston rod, forward and backward cylinder cap etc. usually, piston sleeve is located at the piston rod tail end, and driver plate is connected with the front end of piston rod, is connected with the device for the treatment of transmission by driver plate, therefore, the distance of transmission is the stroke of piston rod movement.Yet in actual use, the client needs the connection distance of oil cylinder adjustable sometimes, all can realize the transmission to device between a certain distance regions, so require oil cylinder transmission distance variable, and cylinder interior does not change.
Summary of the invention
For the technical problem of above-mentioned existence, the purpose of this utility model is: a kind of range-adjustable engineering hydraulic jack by the improvement of structure, makes cylinder body transmission journey variable, and need not to change the cylinder interior structure.
Technical solution of the present utility model is achieved in that a kind of range-adjustable engineering hydraulic jack, comprise cylinder body, forward and backward cylinder cap, and be arranged at piston rod and piston in this cylinder body, described piston is arranged at the tail end of described piston rod, the front end of described piston rod is provided with driver plate, this driver plate and the equipment connection for the treatment of transmission, described piston rod front end is provided with outward extending adjusting section, this adjusting section be provided with regulate screw thread and with the locking nut of this adjustings screw-thread fit, described driver plate is bolted in the described adjusting section.
In the technique scheme, described length of regulating section matches with hydraulic jack distance to be regulated.
When prolong regulating, driver plate is turned to regulating the section outside along regulating screw thread, then locking nut is tightened driver plate and device assembles to be connected to the driver plate side; When shorten regulating, first locking nut is turned to the cylinder body side, then with driver plate to the locking nut side shifting, after device location to be connected is corresponding, locking nut is tightened to the driver plate side.In the movement of regulating on the section, adapt to the needs of different device locations to be connected by driver plate.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages: the utility model arranges at piston rod front end extend outwards and regulates section, regulate on the section outside thread is set, be provided with locking nut in the adjusting section, driver plate is bolted in to be regulated on the section, when needs are adjusted the position of driver plate and equipment to be connected, driver plate is mobile along regulating section, after putting in place locking nut is locked driver plate, thereby the connection needs that adapt to different device locations to be connected, and need not to change the hydraulic jack internal structure, easy to use, flexible.
