Abstract

A kind of hollow oil hydraulic cylinder of built-in viscous damper, belong to oil hydraulic cylinder field, its structure characteristic is the hollow oil hydraulic cylinder changed by the passive Normal hydraulic cylinder used in prior art as built-in viscous damper, viscous damper is contained in the hollow bore of hollow oil hydraulic cylinder, when load and wind carry generation vibration, by the absorbing of viscous damper, vibrational energy is converted into heat energy release, effectively can reduce the friction of hollow hydraulic cylinder piston and casing wall, extend and seal working life; In oil hydraulic cylinder detonation fault, due to the little damping of viscous damper low speed, the feature of at a high speed large damping, can the effect of rapid descent in effective damping accident, and then alleviates Accidents Disasters.

Description

The hollow oil hydraulic cylinder of built-in viscous damper
Technical field
The utility model belongs to oil hydraulic cylinder technical field, is specifically related to a kind of hollow oil hydraulic cylinder of built-in viscous damper.
Background technique
Passive oil hydraulic cylinder is widely applied in multiple industry.Such as hang at engineering vehicle, lift truck; all support at employing oil hydraulic cylinder in cement pump truck; but because engineering vehicle, lift truck the equipment such as to hang in working practice; often impact shock can be produced; this can produce adverse influence to oil hydraulic cylinder in equipment: impact shock can make to produce frictional heating between hydraulic cylinder piston and casing wall; cause in gap increasing, generation and let out, even cause seal failure, cause serious accident.
Summary of the invention
The purpose of this utility model is to provide a kind of hollow oil hydraulic cylinder of built-in viscous damper, effectively can overcome the shortcoming that prior art exists.
The utility model is achieved in that its structure characteristic is the hollow oil hydraulic cylinder changed by the Normal hydraulic cylinder used in prior art as built-in viscous damper.The structure of the hollow oil hydraulic cylinder of described built-in viscous damper is as shown in Figure 1, upper bed-plate 1 bottom is shaped with ears, upper connecting base 3 top is shaped with ears, upper pin 2 is injected in the pin shaft hole on above-mentioned each ears and be hinged, the set screws that upper connecting base 3 is laid by circumferential and bottom are shaped with flange plate, top is that the top of columnar piston 4 connects, piston 4 to be sleeved between the inner cylinder tube 7 of hollow and outer cylinder 6 in oil hydraulic cylinder, the set screws that the upper cylinder cover 5 of ring-type is laid by circumferential is connected with outer cylinder 6 top, the lower cylinder cap 8 being shaped with center hole is arranged on below the lower end flange plate of inner cylinder tube 7 lower end flange plate, the set screws that system biaurite lower connecting base 9 in bottom is arranged by circumferential is connected with outer cylinder 6 lower end surface, lower bearing pin 10 is inserted in the pin shaft hole on the ears on lower connecting base 9 bottom and lower bottom base 11 top and be hinged, viscous damper 12 is placed in inner cylinder tube 7, upper and lower end is respectively by self-lubricating knuckle bearing 13 and upper lower bearing pin 2, 10 connect.
Advantage of the present utility model and good effect are:
viscous damper is contained in the hollow bore of hollow oil hydraulic cylinder, when load and wind carry generation vibration, by the absorbing of viscous damper, vibrational energy is converted into heat energy release, effectively can reduce the friction of hollow hydraulic cylinder piston and casing wall, extend and seal working life; in oil hydraulic cylinder detonation fault, due to the little damping of viscous damper low speed, at a high speed large damping, can the effect of rapid descent in effective damping accident, and then alleviate Accidents Disasters.
