Or there may also be elements placed in the middle.When an element is considered as " connection " another element, it, which can be, is directly connected to
To another element or it may be simultaneously present centering elements.Term as used herein " vertical ", " horizontal ", " left side ",
" right side " and similar statement for illustrative purposes only, are not meant to be the only embodiment.
Unless otherwise defined, all technical and scientific terms used herein and belong to technical field of the invention
The normally understood meaning of technical staff is identical.Term as used herein in the specification of the present invention is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term " and or " used herein includes one or more phases
Any and all combinations of the listed item of pass.
Referring to Fig.1-3, a kind of Novel environmental-sanitation plant machinery locks hydraulic cylinder, including cylinder body 12, is provided on cylinder body 12
First hydraulic fluid port, the first earrings 1 with direction adjusting, drive end bearing bracket 2, special-shaped piston rod 3, supports reset spring 4, is different the second hydraulic fluid port
Type piston 5, retaining ring 6, block 7, locking nut 8, special-shaped rear end cap 9, collet chuck 10, the second earrings of band blind flange 11, close
Seal 13, the first support ring 14 and the second support ring 15；
Wherein, the first hydraulic fluid port is communicated with hydraulic cylinder rod chamber, and the second hydraulic fluid port is communicated with hydraulic cylinder rodless cavity.
Support reset spring 4, retaining ring 6, block 7, by locking nut 8 is fixed on piston-rod end at special-shaped piston 5.
Special-shaped rear end cap 9 is welded on 12 end of cylinder body of hydraulic oil cylinder.
Collet chuck 10, the blind flange 11 of the second earrings of band are screwed with special-shaped rear end cap 9.
Special-shaped piston 5 is sealed with special-shaped piston rod 3 by sealing ring 13, the first support ring 14, the second support ring 15
And guiding.
It is slided between special-shaped piston 5 and special-shaped piston rod 3 by support reset spring 4 is opposite.
Special-shaped 3 device of piston rod and 10 device of collet chuck carry out end mechanical caging.
The present invention is divided into two processes at work, the first process: process of locking when locking cylinder withdrawal: pressure oil passes through
Hydraulic fluid port A enters hydraulic cylinder rod chamber such as Fig. 3, special-shaped piston 5, special-shaped piston rod 3 by pressure oil zone of action piston bar to
It moves right, the oil of hydraulic cylinder rodless cavity flows back to fuel tank through hydraulic fluid port B, and hydraulic cylinder is withdrawn；When the block 7 on special-shaped piston rod 3 touches
When to collet chuck 10, collet chuck 10 is opened, while collet chuck 10 moves up along block 7 and pushes special-shaped piston 5 to moving to left,
Reset spring 4 compresses, and special-shaped piston rod 3 continues to move right under the action of pressure oil, and collet chuck 10 closes after having crossed block 7
It closes, such as Fig. 2；It pushes special-shaped piston 5 to move right under the action of reset spring 4 and pressure oil, is withstood until special-shaped piston 5
Retaining ring 6, special-shaped 3 end of piston rod contact blind flange 11, and hydraulic cylinder withdrawal movement is completed；At this time in the effect of reset spring 4
Lower collet chuck 10 is stuck between special-shaped piston 5 and block 7, is no longer exited, and mechanical caging such as Fig. 1 is completed.
Second process: locking cylinder unlocks stretching process: oil cylinder unlocks stretching process and retraction locking process is just opposite；
Pressure oil enters hydraulic cylinder rodless cavity by hydraulic fluid port B, pushes special-shaped piston 5 to be moved to the left, reset spring 4 compresses, while different
Type piston rod 3 by power to the left under the action of pressure oil, shake off under the action of piston rod power to the left by collet chuck 10
Block 7, such as Fig. 2；Special-shaped piston rod 3 drives devices above: reset spring 4, special-shaped piston 5, retaining ring 6, block 7, lock at this time
Tight nut 8 continues to move on the left of hydraulic cylinder under the action of pressure oil, until special-shaped piston rod 3 contacts that drive end bearing bracket 2 stops,
Hydraulic cylinder completes stretching process.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
