Specific embodiment
The structure of the utility model vibrating screen support damping device is as shown in Figure 1, comprising: screen(ing) machine support base 1, arm base for post
2,3 three parts of upper limit plate form.
Screen(ing) machine support base 1 is between arm base for post 2 and upper limit plate 3.Arm base for post 2 primarily serve support, vibration damping and
Lower limit effect.Upper limit plate 3 primarily serves vibration damping and upper limit effect.
The screen(ing) machine support base 1 will support backup plate 1-6 and the side plate of vibrating screen cabinet to be fastened together by rivet,
One is formed with screen box, is the hanging support construction of entire vibrating screen.
First spring spool 1-3 and the first rubber column 1-2 is connect by bolt with horizontal supporting plate 1-5, is played to first
The effect of spring guiding and limit.
Reinforcing rib 1-4 is to horizontal supporting plate 1-5 with enough support degrees.
First spring 1-1 is located above horizontal supporting plate 1-5, and second spring 1-7 is located at below horizontal supporting plate, and the two is right
Claim uniformly installation.
The arm base for post 2 is fixed with ground, is the fixed structure for propping up vibrating screen.
As shown in figure 4, abrasion-proof rubber cushion 2-2, second spring sleeve 2-3 and the second rubber column 2-4 pass through bolt and arm column
Lower bottom base 2-1 connection.
Guiding gusset 2-5 and pedestal reinforcing rib 2-7 has reinforcement effect, and is oriented to gusset 2-5 there are also the peaces of upper limit plate 3
Fill guiding role.
What the upper limit plate can limit screen(ing) machine support base 1 moves upwards amplitude, plays certain position-limiting action.Upper limit
Abrasion-proof rubber cushion, the first spring spool 3-3 and the first rubber column 3-4 are sequentially fixed on upper limit plate 3 by bolt in plate.Its
In, abrasion-proof rubber cushion also functions to certain buffer function in vibration, to reduce vibration impact to upper limit plate 3 and arm base for post
2 vibration influences.Guide groove 3-6 enables upper limit plate 3 smoothly to install and move up and down adjustment on arm base for post 2.In determination
Behind the position of limit plate 3, it is fastenedly connected by bolt and upper limit backup plate 2-6.
Installation site of the first spring and second spring 1-7 of the screen(ing) machine support base 1 on horizontal horizontal supporting plate 1-5
Be centrosymmetric distribution, in order to be bolted fixation.
Spacing in the package assembly, between first rubber column of two of the first both ends of the springD 1It can be according to vibration
Width limits range by calculating the size of design rubber column in advance to change.
The the second rubber intercolumniation of two of second spring both endsD 2Similarly.
The coefficient of elasticity of the first spring 1-1 is less than or equal to second spring 1-7, and the first spring 1-1 requires nature installation
Or it pre-tightens downwards.
The coefficient of elasticity of the rubber column used should be greater than the coefficient of elasticity of spring used.
Screen(ing) machine support base 1 and 2 spacing of the arm base for post at least 10mm, in order to avoid generate interference.
The working principle of the utility model vibrating screen support damping device is:
In vibrating screen normal vibration, rubber column and spring spool only serve spring guiding role, the first spring and second
Spring plays vibration damping and the supporting role of vibrating screen, and abrasion-proof rubber cushion then plays certain buffer function；But vibrating screen start and
When shutting down generation resonance, the big displacement amplitude upward or downward that vibrating screen drives support base to generate, when downward displacement amplitude is super
Certain amplitude is crossed, support spring is caused to be compressed to certain deflectionD 1When, second below arm base for post and screen(ing) machine support base
Rubber column contact, directly increases the support stiffness of screen(ing) machine, plays the role of lower limit；
When vibrating screen moves upwards, the deformation of the first spring increases, and elastic force increases, and amplitude and the first spring-compressed are more than
Certain amplitudeD 2When, cause upper limit plate to contact with the first rubber column above screen(ing) machine support base, directly under increase vibrating screen
Surging, to play the role of upper limit.
