Description
Technical field
It is especially a kind of suitable for quickly playing perpendicular local synchronization three-level the utility model relates to hydraulic cylinder technical field
Cylinder.
Background technique
Playing perpendicular hydraulic cylinder is the device converted hydraulic energy to mechanical energy, is used in previous domestic heavy mechanical equipment
Perpendicular hydraulic cylinder is played, the overwhelming majority is single cylinder design, if output force request is constant, the pressure of system is not easy to adjust；Design later
The perpendicular hydraulic cylinder that multistage can be adjusted is gone out.Currently, it is mostly synchronized cylinder that three-level, which plays perpendicular hydraulic cylinder, and release step by step,
Biggish strength is required when releasing step by step, this results in stretching speed slow, can not meet customer need well.
Utility model content
Technical problem to be solved by the utility model is: overcoming the deficiencies in the existing technology, a kind of be suitable for quickly is provided
Play perpendicular local synchronization three-level cylinder.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of same suitable for quickly playing perpendicular part
Three-level cylinder is walked, including outer sleeve, cylinder bottom, the first-stage cylinder with first stage piston and first stage piston bar, there is second piston and second level
The secondary cylinder of piston rod, three-level cylinder, sealed tube, oil guide pipe and head with three-level piston and three-level piston rod, the level-one
Piston, second piston and three-level piston are respectively placed in outer sleeve, in first stage piston bar and in second piston rod, the sealed tube
It is fixedly connected with three-level piston, the oil guide pipe is fixedly connected with first stage piston, and is passed through second piston and stretched to second piston
In bar, the outer sleeve is fixedly connected with cylinder bottom, and hydraulic fluid port A is provided on the cylinder bottom, and the head is equipped with hydraulic fluid port B.
It further limits, the first stage piston is connect by cylindrical pair I with outer sleeve, and the second piston passes through cylinder
Secondary II is connect with first stage piston bar, and the three-level piston is connect by cylindrical pair III with second piston rod.
It further limits, the outer sleeve is welded on cylinder bottom.
The beneficial effects of the utility model are: starting strength is big when the utility model plays perpendicular, rising, vertical angle degree is increasing
When, power is smaller and smaller, and in the case where meeting identical stress, such cylinder is smaller than synchronized cylinder size, and than ordinary telescopic cylinder speed
Fastly, it can satisfy every demand of client.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1. outer sleeves, 2. cylinder bottoms, 3. first-stage cylinders, 4. secondary cylinders, 5. three-level cylinders, 6. sealed tubes, 7. oil guide pipes, 8.
Head, 9. hydraulic fluid port A, 10. hydraulic fluid port B.
Specific embodiment
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram only to show
Meaning mode illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
As shown in Figure 1, the present embodiment is a kind of suitable for quickly playing perpendicular local synchronization three-level cylinder, including outer sleeve 1, cylinder
Bottom 2, the secondary cylinder 4 with second piston and second piston rod, has the first-stage cylinder 3 with first stage piston and first stage piston bar
The three-level cylinder 5 of three-level piston and three-level piston rod, sealed tube 6, oil guide pipe 7 and head 8, first stage piston are placed in outer sleeve 1 simultaneously
It is connect by cylindrical pair I with outer sleeve 1, second piston is placed in first stage piston bar and is connected by cylindrical pair II and first stage piston bar
It connects, three-level piston is placed in second piston rod and is connect by cylindrical pair III with second piston rod, sealed tube 6 and three-level piston
It is fixedly connected, oil guide pipe 7 is fixedly connected with first stage piston, and is passed through second piston and stretched in second piston rod, and outer sleeve 1 welds
It connects on cylinder bottom 2, hydraulic fluid port A9 is provided on cylinder bottom 2, head 8 is equipped with hydraulic fluid port B10.
When local synchronization three-level cylinder is unfolded, the logical oil of 2 upper hydraulic fluid port A9 of cylinder bottom, 3 setting in motion of first-stage cylinder, while secondary cylinder 4 is same
Step movement, three-level cylinder 5 are keeping opposing stationary with secondary cylinder 4；It is complete after first-stage cylinder 3 and secondary cylinder 4 move to end of travel simultaneously
At grade is changed, hydraulic oil is entered in 4 piston rod of secondary cylinder by oil guide pipe 7, three-level cylinder 5 is released, it is dynamic to be finally completed expansion
Make.
When local synchronization three-level cylinder is shunk, hydraulic oil is entered in 5 piston rod of three-level cylinder by the hydraulic fluid port B10 of head 8, three-level
Cylinder 5 starts to shrink, and first-stage cylinder 3 and secondary cylinder 4 are stationary, when 5 piston contact of three-level cylinder is to 4 piston of secondary cylinder, first-stage cylinder 3
With 4 synchronous of secondary cylinder, three-level cylinder 5 is moved with secondary cylinder 4, until contacting with 2 end face of cylinder bottom, entire local synchronization three-level
Cylinder is shunk in place.
Above embodiment is only to illustrate the technical ideas and features of the present invention, and its object is to allow be familiar with this skill
The personage of art can understand the content of the utility model and be implemented, and the protection model of the utility model can not be limited with this
It encloses, all equivalent change or modifications according to made by the spirit of the present invention essence should all cover the protection model in the utility model
In enclosing.
