Abstract
The utility model discloses a safety limiting device of an oil cylinder. The safety limiting device of the oil cylinder comprises a suspension arm, a hooking chain, the telescopic oil cylinder, a suspension bracket, an oil cylinder bumper, a hinge pin and a cotter pin, wherein the suspension arm is connected with the suspension bracket through the hooking chain, the telescopic oil cylinder is connected with the suspension bracket through a shaft, one end of the oil cylinder bumper is fixed to the shaft of the telescopic oil cylinder through the hinge pin, the oil cylinder bumper is hollow and 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 and is used for fixing the oil cylinder bumper, and the telescopic oil cylinder is locked and can not contract. According to the safety limiting device of the oil cylinder, due to the fact that the oil cylinder bumper is additionally arranged, personal safety of workers is guaranteed during maintenance; when a rotary blade roller does not work, the rotary blade roller is protected from sudden falling caused by failures of a hydraulic system, and damage is avoided.
Description
Technical field
The utility model relates to the tillage machinery suspension system technical field of farm machinery, especially relates to a kind of oil cylinder safety caging device.
Background technique
Tiller suspension system is mainly made up 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 in the time keeping in repair, may cause personal safety injury.
Model utility content
Have the defect of potential safety hazard in order to overcome existing tiller suspension system, the utility model provides a kind of tiller suspension system with oil cylinder safe spacing.
The utility model 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 by bearing pin on the axle of telescopic oil cylinder, 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.
The utility model beneficial effect is: the utility model provides one to have oil cylinder safety caging device, increases an oil cylinder bumper, and connects by a cotter pin, and oil cylinder is locked, can not carry out contractive action; After sales service need to be rolled rise by rotary blade, in the time keeping in repair, has played protection personnel personal safety; Rotary blade rolls while work, rotary blade need to be rolled to rise, and having played that protection rotary blade rolls not can be because of the hydraulic system fault damage causing of dropping suddenly.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
Fig. 1 is the utility model oil cylinder safety caging device structural drawing.
Fig. 2 is the utility model oil cylinder bumper figure.
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.
When concrete enforcement, describe the utility model in detail below with reference to Fig. 1, Fig. 2, the utility model 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 by bearing pin 6 on the axle 9 of telescopic oil cylinder, 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, in the time 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, having played that protection rotary blade rolls not can be because of the hydraulic system fault damage causing of dropping suddenly.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 does not lock, 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 utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
