Description
Technical field
The utility model relates to suspension and supports.
Background technique
Currently, spring hanger is in building etc. in industries, vibration influence environment that equipment or pipeline are generated by equipment or
External vibration influences equipment and plays reduction vibration harm, xegregating unit noise, the ideal damper for protecting environment.
In the design of suspension and support, spring has become a kind of common knowledge as the indispensable part of spring support hanging frame, when
When under certain particular surroundings, such as all part requirements are without metal, non-magnetic material；And spring is as a kind of elastic force
There is provided part, have very big unstable factor, such as spring fracture spring material exhaustion creep or spring material
The problems such as surface corrosion, rust hole, rust staining of material etc.；Once and there is problem above in spring, the function of spring support hanging frame is with regard to complete
It loses.Spring support hanging frame can not provide the effect of damping, noise reduction just for equipment.
So seeking for the alternative solution of spring, has become one of research direction of spring support hanging frame.
Utility model content
Purpose of the utility model is to solve the deficiencies of the above prior art and provide a kind of without using the simple of spring
Suspension and support.
A kind of simple suspension and support, including body frame and left and right damper, the body frame inside are equipped with cylindrical cavity, cavity
It is provided with main piston, the lower surface of main piston and cavity inner wall form closed main grease chamber, be also connected with sunpender on main piston, institute
The sunpender stated passes through main grease chamber and reaches the outside of body frame；The left and right damper is vertically fixed on the side of body frame,
Left and right piston is respectively equipped with inside left and right damper, left damper internal cavities are divided into left grease chamber and a left side by the left piston
Right damper internal cavities are divided into right grease chamber and right discharge chambe by discharge chambe, the right piston；
The left and right grease chamber is communicated with main grease chamber, and internal filled with hydraulic oil；The left and right discharge chambe is envelope
Space is closed, and internal filled with nitrogen.
In order to guarantee to seal, prevents the hydraulic oil in each grease chamber from revealing, straight line is equipped between the sunpender and body frame
Bearing and star sealing ring.
In order to provide certain pretightning force, the nitrogen filled in the left and right discharge chambe, pressure is 3 to 5 atmosphere
Pressure.
In order to improve the service life of body frame, preventing body frame from bearing, pulling force is excessive to cause body frame to damage, the body frame
Material is hard aluminium alloy.
Left and right piston overturning in order to prevent, causes left and right discharge chambe to reveal, thus by among smooth base to main grease chamber,
The thickness of the left and right piston and the ratio of diameter are between 0.8 to 2.
The utility model has the advantages that
1, the use of spring is replaced with the structure of left and right damper, this product can be used to not be available spring
Occasion, such as require without magnetic, without the workshop of metal.And it can completely avoid since a series of defects of spring cause to prop up
The short problem of hanger service life.
2, using the compressible principle of air, left and right discharge chambe is set, and fills the compression sky of certain pressure intensity in it
Gas.While carrying out volume-exchange between left and right discharge chambe and main grease chamber, very smooth elastic force is provided for sunpender.The knot
Structure has been accomplished complete noiseless compared with spring, and its elastic force provided is also more steady.
3, the vertical position of body frame is arranged in left and right discharge chambe, can accomplish left and right discharge chambe almost very close
Envelope, substantially increases the leakproofness of left and right discharge chambe, gas leakage problem will not occur substantially.And possible leak point exists
Between sunpender and body frame, may reveal object herein is only hydraulic oil, can improve suspension and support by the strategy of intermittent oiling
Service life safeguarded more simple, conveniently compared with spring support hanging frame.

Specific embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further
It is described in detail, which is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.
As shown in Figure 1, a kind of simple suspension and support, including body frame 1 and left damper 2, right damper 3, the body frame 1
Material is hard aluminium alloy.
As shown in Fig. 2, being equipped with cylindrical cavity inside the body frame 1, cavity is provided with main piston 4, the following table of main piston 4
Face and cavity inner wall form closed main grease chamber 11, and sunpender 5 is also connected on main piston 4, and the sunpender 5 passes through main grease chamber 11
And reach the outside of body frame 1；Linear bearing and star sealing ring are equipped between the sunpender 5 and body frame 1.
The left and right damper is vertically fixed on the side of body frame, is respectively equipped with left piston inside left and right damper
22, right piston 32, the thickness of the left and right piston and the ratio of diameter are between 0.8 to 2.
Left 2 internal cavities of damper are divided into left grease chamber 23 and left discharge chambe 21 by left piston 22, and the right piston 32 will
Right 3 internal cavities of damper are divided into right grease chamber 33 and right discharge chambe 31；
The left and right grease chamber is communicated with main grease chamber 11, and internal filled with hydraulic oil；The left and right discharge chambe is
Enclosure space, and it is internal filled with nitrogen, the interior nitrogen filled of the left and right discharge chambe, pressure is 3 to 5 atmospheric pressure.
Working condition:
The bottom end phase of the equipment that the upper end of body frame 1 is fixed on the ceiling in workshop, and needs vacantly to install and sunpender
Even.
When equipment is impacted, sunpender 5 will pull main piston 4 and move downward, and main piston compresses main grease chamber 11 at this time
Volume, the hydraulic oil in main grease chamber 11 are flow among left grease chamber 23 and right grease chamber 33.
Left and right grease chamber is pressurized and pressure is transferred to left and right piston.The compression of left and right piston is left, by the volume of discharge chambe,
It compresses indoor nitrogen to be pressurized, pressure becomes larger, volume becomes smaller, and since compression temperature has certain rising.The temperature of rising
Degree can be dispersed to external radiation, and energy source is impact force workmanship；And after impact force terminates effect, all piston resets,
Single unit system waits impact next time.
When after a period of use, can be hung according to the loss situation of hydraulic oil, addition hydraulic oil appropriate to extend branch
The service life of frame.Compared with conventional springs structure, safeguard more simple and convenient.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
