Abstract
The invention discloses an oil cylinder safety limiting device which comprises a hanging arm, a hanging connection lock chain, a telescopic oil cylinder, a hanging frame, an oil cylinder bumper, a pin roll and a cotter pin. The hanging arm is connected with the hanging frame through the hanging connection lock chain, the telescopic oil cylinder is connected with the hanging frame through a shaft, one end of the oil cylinder bumper is fixed on the shaft of the telescopic oil cylinder through the pin roll, the oil cylinder bumper is hollow, and the oil cylinder bumper penetrates through the shaft of the telescopic oil cylinder. An opening is formed in the oil cylinder bumper, the cotter pin penetrates through the opening to fix the oil cylinder bumper, and the telescopic oil cylinder is locked and can not make telescopic movement. According to the oil cylinder safety limiting device, the oil cylinder bumper is additionally arranged, and when maintaining is conducted, the personnel safety of people is guaranteed; when a rotary tillage cutter roller does not work, the rotary tillage cutter roller is prevented from falling down suddenly to be damaged due to hydraulic system faults.
Description
Technical field
The tillage machinery suspension system technical field that the present invention relates to farm machinery, especially relates to a kind of oil cylinder safety caging device.
Background technique
Tiller suspension system is mainly comprised of hydraulic system, suspension arm, suspension chain, hanging oil cylinder and suspending frame, and telescopic oil cylinder is the critical piece that farming machine knife rolls assembly lift adjustment.Farming machine knife rolls does not work, and rotary blade need to be rolled to rise, hydraulic work system, and oil hydraulic cylinder push rod jack-up suspending frame, suspending frame is mentioned suspension arm by articulating chain, and rotary blade is got away and is begun to rise.But, if hydraulic system fault and dropping suddenly not only may cause farming machine knife to roll damage; And rotary blade rolls when keeping in repair, may cause personal safety injury.
Summary of the invention
In order to overcome existing tiller suspension system, there is the defect of potential safety hazard, the invention provides a kind of tiller suspension system with oil cylinder safe spacing.
The present invention requires the technical problem solving to be achieved through the following technical solutions:
A kind of oil cylinder safety caging device, comprise suspension arm, articulate chain, telescopic oil cylinder, suspending frame, oil cylinder bumper, bearing pin and cotter pin, described suspension arm is connected with suspending frame by articulating chain, described telescopic oil cylinder is connected with suspending frame by axle, one end of described oil cylinder bumper is fixed on the axle of telescopic oil cylinder by bearing pin, oil cylinder bumper hollow, oil cylinder bumper is through telescopic oil cylinder axle, oil cylinder bumper is provided with opening, cotter pin is through opening fixed oil cylinder bumper, telescopic oil cylinder is locked, can not carry out contractive action.
One end of described oil cylinder bumper bar is fixed on by bearing pin on the axle of telescopic oil cylinder, and the other end of oil cylinder bumper can be along a sideway swivel of telescopic oil cylinder axle.
Described oil cylinder bumper is provided with two openings, and an opening is positioned in the middle of the top of oil cylinder bumper, and another opening is positioned at bottom one side of oil cylinder bumper.
Beneficial effect of the present invention is: the invention provides a kind of oil cylinder safety caging device that has, increase an oil cylinder bumper, and connect by a cotter pin, oil cylinder is locked, can not carry out contractive action; After sales service need to be rolled rise by rotary blade, when keeping in repair, has played protection personnel personal safety; Rotary blade rolls while not working, rotary blade need to be rolled to rise, has played protection rotary blade and has rolled not the damage that can drop suddenly and cause because of hydraulic system fault.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention will be further described:
Fig. 1 is oil cylinder safety caging device structural drawing of the present invention.
Fig. 2 is oil cylinder bumper figure of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
During concrete enforcement, below with reference to Fig. 1, Fig. 2, describe the present invention in detail, the present invention mainly comprises: suspension arm 1, articulate chain 2, telescopic oil cylinder 4, suspending frame 3, oil cylinder bumper 5, bearing pin 6, cotter pin, opening 7, opening 8 and telescopic oil cylinder axle 9.Suspension arm 1 is connected with suspending frame 3 by articulating chain 2, telescopic oil cylinder 4 is connected with suspending frame 3 by axle 9, one end of oil cylinder bumper 5 is fixed on the axle 9 of telescopic oil cylinder by bearing pin 6, oil cylinder bumper 5 hollows, oil cylinder bumper 5 is through telescopic oil cylinder axle 9, and the other end of oil cylinder bumper 5 can be along a sideway swivel of telescopic oil cylinder axle 9.Oil cylinder bumper is provided with two openings, and an opening 7 is positioned in the middle of the top of oil cylinder bumper, and another opening 8 is positioned at bottom one side of oil cylinder bumper.Cotter pin is through opening 8 fixed oil cylinder bumpers 5, and telescopic oil cylinder 4 is locked, can not carry out contractive action.
Farming machine knife rolls does not work, rotary blade need to be rolled to rise, hydraulic work system, telescopic oil cylinder axle jack-up suspending frame, suspending frame is mentioned suspension arm by articulating chain, rotary blade is got away and is begun to rise, oil cylinder bumper is rotated to the position that overlaps with telescopic oil cylinder axle, and cotter pin is through opening 8, and telescopic oil cylinder is locked, can not carry out contractive action, play the safe spacing of oil cylinder.After sales service need to be rolled rise by rotary blade, when keeping in repair, has played protection personnel personal safety; When rotary blade rolls not need of work, rotary blade need to be rolled to rise, play protection rotary blade and rolled not the damage that can drop suddenly and cause because of hydraulic system fault.When farming machine knife rolls work, rotating hydraulic cylinder bumper leaves telescopic oil cylinder axle, and cotter pin is through opening 7, and telescopic oil cylinder is locking not, and telescopic oil cylinder axle can stretch, and does not affect the normal work that farming machine knife rolls.
More than show and described basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
