Abstract
The utility model related to a hand-operated adjustable resilient rubber draft gear, which comprises: an adjustable piston rod (1), a lock nut (2), a piston rod casing (3), a cylinder cover (4), a cylinder body (5), a piston head (6), a piston (7) and a sealing device. A hole for the piston head passing through is arranged at the piston head and a hole for the piston passing through is arranged at a lower end of the adjustable piston rod. A superposed area between the piston and the piston head both at the lower end of the adjustable piston rod is adjusted to adapt to different load conditions. The hand-operated adjustable resilient rubber draft gear is mainly applied in the important fields of metallurgy, military industry, railway, aviation, aerospace, building, and the like, performs functions of buffering impacts of equipment and protecting equipment, and is convenient in installation and easy in maintenance.
Description
Technical field
The utility model relates to the elastic cement buffer of manual adjustable, and relating to a kind of is the damper of medium with the elastic colloid, and elastic colloid is a kind of compressible semifluid macromolecular material.
Background technique
In recent years; Continuous development along with the elastic damping body technique; Elastic damping damping, buffer technology are widely used in the fields such as metallurgy, military project, railway, space flight, aviation, building gradually, especially have the elastic cement buffer of manual adjustable function; Scope that can the manual tune damping force and adapt to the load working condition of variation and make it reach optimum Working, thus protection equipment can not be damaged in vibration.
In vibration, avoid the possibility destroyed though the elastic damping buffer device that has has in the market reduced equipment, be difficult to adapt to different impact and the complicated work condition environment that changes, both improved cost and also reduced efficient if change damper simultaneously.
The model utility content
According to background technique; The utility model technical problem to be solved provides a kind of adjustable elastic cement buffer of anti-vibration load that has; When load change, can manual tune adapt to different environment, so that play the effect of damping more efficiently.This buffering piston place had boxes out, and the piston head that cooperates with it simultaneously had the mouth of staying equally, and the upper end is adjustable piston rod, stays open area by the mistake that this piston rod Spin Control overlaps.
The utility model is realized through following technological scheme: the manual adjustable elastic cement buffer; Comprise adjustable piston rod, locking nut, piston rod cover, cylinder cap, cylinder body, piston head, piston and seal arrangement composition; The piston head place has piston head to cross to stay mouth; Adjustable piston-rod lower end has piston to cross to stay mouth, can adapt to different load working conditions through the piston of regulating piston bar lower end and the coincidence area of piston head.
The composition original paper of manual adjustable elastic cement buffer is all cylindrical, and cylinder interior is to have compressible high polymer elastic damping body compound medium.When equipment receives the little vibration of impact energy; The elastic damping body medium that piston rod (1) compression cylinder is inner; The cylinder interior damping force also increases thereupon, and the graduation line on regulating piston bar (1) the upper end locking nut (2) of taking advantage of a situation makes the piston head (6) and the mistake of piston (7) stay mouth bigger.When equipment receives the big vibration of impact energy, regulating piston bar (1) upper end locking nut (2) in like manner, it is mouthful less that the piston head (6) and the mistake of piston (7) are stayed.When impacting the external force disappearance, the elastic potential energy of utilizing resisting medium to store in advance just can automatically reset.Along with the requirement of different loads all can satisfy the demands by regulating piston bar upper end locking nut (2); This kind buffer not only can adapt to work condition environment complicated and changeable; Making things convenient for efficiently simultaneously, also reduced the cost of exchange buffering device, is that the ideal of protection various device is selected.
Owing to adopted technique scheme, the utlity model has following advantage and effect:
1. the utility model has utilized modulating valve can change impact energy to satisfy different operating modes.
2. the utility model can protect equipment not to be damaged when equipment bears the different impact vibration.
3. model utility has adopted a kind of semifluid macromolecular material, has stronger compressibility, particular chemical inertia and good thermostability.
Description of drawings
Fig. 1 is the utility model structure collectivity cross-sectional schematic.
Fig. 2 crosses when bearing small-sized impact shock for the utility model buffer and stays the open area schematic representation.
Fig. 3 crosses when bearing large-scale impact shock for the utility model buffer and stays the open area schematic representation.
Among the figure: the adjustable piston rod of 1-, 2-locking nut, 3-piston rod cover, 4-cylinder cap, 5-cylinder body, 6-piston head, 7-piston
Embodiment
Referring to Fig. 1; The manual adjustable elastic cement buffer; It is characterized in that: comprise adjustable piston rod (1), locking nut (2), piston rod cover (3), cylinder cap (4), cylinder body (5), piston head (6), piston (7) and seal arrangement composition; The piston head place has piston head to cross to stay mouth, adjustable piston-rod lower end to have piston to cross to be stayed mouth, can adapt to different load working conditions through the piston of regulating piston bar lower end and the coincidence area of piston head.
Referring to Fig. 2,3, the composition original paper of buffer is all cylindrical, and cylinder interior is to have compressible high polymer elastic damping body compound medium.When equipment receives the little vibration of impact energy; The elastic damping body medium that piston rod (1) compression cylinder is inner; The cylinder interior damping force also increases thereupon; Take advantage of a situation graduation line on regulating piston bar (1) the upper end locking nut (2), it is mouthful bigger that the piston head (6) and the mistake of piston (7) are stayed, shown in figure (2).When equipment receives the big vibration of impact energy, regulating piston bar (1) upper end locking nut (2) in like manner, it is mouthful less that the piston head (6) and the mistake of piston (7) are stayed, shown in figure (3).When impacting the external force disappearance, the elastic potential energy of utilizing resisting medium to store in advance just can automatically reset.
Can know that by Fig. 2 during regulating piston boom end knob to this position, this moment, damping force was big slightly, can know that by crossing the area that stays mouth this operating mode belongs to small-sized impulsive load vibration.
Can know that by Fig. 3 during regulating piston boom end knob to this position, this moment, damping force was bigger, can know that by crossing the area that stays mouth this operating mode belongs to large-scale impulsive load vibration.
This device mainly makes it at a load working condition that the scope endoadaptation is different through the manual tune damping force that is used for of power, thereby improves the effect of damping.
