Abstract
The invention discloses a third-level hydraulic cylinder, which comprises an outer cylinder barrel. A third-level cylinder is arranged in the outer cylinder barrel, a second-level cylinder is arranged in the third-level cylinder, and a first-level cylinder is arranged in the second-level cylinder; friction connection blocks are arranged among cylinder bodies; the inner wall of the rear end of the outer cylinder barrel is provided with a groove, a clamping plate is clamped in the groove, the rear end of the outer cylinder barrel is also provided with a rear cover, and the clamping plate is connected with the rear cover through a bolt; and the clamping plate is a circular metal plate. A structural form that three levels of hydraulic cylinders are sleeved together is adopted, and hydraulic oil pushes the first-level cylinder to eject when acting and drives the second-level cylinder and the third-level cylinder when a specific length is reached, so that the installation space is reduced, the setting and adjustment of system pressure are facilitated on occasions requiring unchanged output force, multilevel speed extension is realized under certain flow, material consumption and the weight of a main machine are reduced and transportation and hoisting are facilitated.
Description
Technical field:
The present invention relates to the hydraulic equipment field, a kind of specifically three grades of oil hydraulic cylinders.
Background technique:
Oil hydraulic cylinder is the device that hydraulic pressure can be converted to mechanical energy, and the oil hydraulic cylinder that adopts in domestic in the past winch and other heavy mechanical equipments is most for single cylinder designs, and constant if ouput force requires, the pressure of system is not easy to regulate; Imagination provides a kind of oil cylinder of new structure, can multistagely regulate.
Summary of the invention:
The invention provides a kind of three grades of oil hydraulic cylinders, the mode of structure that is fitted together by three grades of hydraulic cylinders, make time spent promotion first-stage cylinder when hydraulic oil and eject, drive secondary cylinder, three grades of cylinders during to specific length, reduced installing space, require constant occasion in ouput force, be convenient to the setting and the adjusting of system pressure, the realization multistage speed is stretched out under certain flow, reduces spillage of material, alleviate the weight of main frame, be convenient to transporting and hoisting.
The technical solution used in the present invention is:
A kind of three grades of oil hydraulic cylinders comprise outer cylinder: three grades of cylinders are installed in the outer cylinder, in three grades of cylinders secondary cylinder are installed, first-stage cylinder is installed in the secondary cylinder; Be provided with the friction contiguous block between each cylinder body; Outer cylinder rear end inwall is fluted, is installed with clamp in the groove, and the outer cylinder rear end also is equipped with bonnet, and clamp is connected with bonnet by bolt.
Described clamp is the circular shape sheet metal.
Advantage of the present invention is:
The mode of structure that the present invention is fitted together by three grades of hydraulic cylinders, making time spent promotion first-stage cylinder when hydraulic oil ejects, drive secondary cylinder, three grades of cylinders during to specific length, reduced installing space, required constant occasion, be convenient to the setting and the adjusting of system pressure in ouput force, the realization multistage speed is stretched out under certain flow, reduce spillage of material, alleviate the weight of main frame, be convenient to transporting and hoisting.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment:
A kind of three grades of oil hydraulic cylinders comprise outer cylinder 4: be equipped with in the outer cylinder 4 in 3, three grades of cylinders 3 of three grades of cylinders secondary cylinder 2 is installed, first-stage cylinder 1 is installed in the secondary cylinder 2; Be provided with the friction contiguous block between each cylinder body; Outer cylinder 4 rear end inwalls are fluted, are installed with clamp 6 in the groove, and the outer cylinder rear end also is equipped with bonnet 5, and clamp 6 is connected with bonnet 5 by bolt; Described clamp 6 is the circular shape sheet metal.
