Abstract
The utility model provides a vibration isolation platform electronic balance which is mainly composed of a balance cover, a vibration isolation buffer, and a needle passing device which supports a middle plate and a base plate, wherein, the cover surface of a cover plate is formed in the way that a double-layer steel plate is clamped with channel steel to form a stiffening rib. The vibration isolation buffer is provided with an air inflating tire (2) and a compression spring (3) to be used for vibration isolation buffering. The middle plate is provided with a circular ring (11), and a steel ball (6) put in the circular ring can freely roll in the middle. When a weighing object has momentary vertical downward or horizontal impulsive force, the weighing accuracy of a sensor is not affected. The vibration isolation platform electronic balance has the advantages of reasonable design, compact structure and accurate stress of the sensor, and can completely meet the requirement of object weighing of smelting shops of metallurgy industry.
Description
The utility model relates to a kind of vibration-isolating platform electronic scales that is applicable to the weighing object, is particularly useful for having the object weighing of instantaneous impulse force, belongs to the GO1G19/00 class.
Before the utility model; at metallurgy industry; particularly when the weight of smelting shop, generally all be to use driving to be put on the weighing platform by the weighing object at weighing molten iron or steel scrap etc.; making in this way, the weighing object all can produce very big impulse force to the weighing platform table top; damage whole weighing equipment easily; for example used common table top electronic scales and with spring as electronic scales that overload protective device is installed on pit foundation of impact damper etc.; though they respectively have advantage; it is poor that but its weak point is a system stability; yielding; Installation and Debugging are difficulty, is difficult for applying.
The purpose of the utility model be to manufacture and design a kind of can satisfy produce needs, weighing accurately, the vibration-isolating platform electronic scales that can under mal-condition, use again.This scale can bear the vibrations that temporary impact causes, through actual test more than a year, has reached technical standard and the accuracy of industrial process with electronic scales.
This vibration-isolating platform electronic scales is to realize its purpose in the following way.
Earlier with cover plate, isolation damper, intermediate plate and the bedplate of vibration-isolating platform electronic scales according to the design drawing manufacturing with install.When be equipped with the weighing object hang on the cover panel that body is put into the vibration-isolating platform electronic scales time, its weight pass on the doughnut that is full of gas and compression spring on, they can play and slow down the effect of weight to scale body impulse force.Thereafter weight of heavy passes on the intermediate plate, because of being welded with n annulus on the intermediate plate, is placed with steel ball in each annulus, and steel ball can freely roll in annulus, and their effect can also slow down the horizontal thrust of weight to the scale body.Intermediate plate nestles up the bedplate that sensor is housed, and on the bottom surface of bedplate sensor is housed, thus weight of heavy be transported on the weight display by sensor, with the purpose that realizes that weighed object is heavy.
Below in conjunction with accompanying drawing the utility model is done more detailed explanation.
Fig. 1 is a vibration-isolating platform electronic scales forward broken section structural drawing, and it also is a specification digest accompanying drawing of the present utility model.
Fig. 2 is the scale lid partial sectional view of vibration-isolating platform electronic scales.
Fig. 3 is the forward sectional structure chart of the isolation damper of vibration-isolating platform electronic scales.
Fig. 4 is the intermediate plate front view of vibration-isolating platform electronic scales.
Fig. 5 is the intermediate plate vertical view of vibration-isolating platform electronic scales.
Fig. 6 is the bedplate front view of vibration-isolating platform electronic scales.
Fig. 7 is the bedplate vertical view of vibration-isolating platform electronics stalk.
As Fig. 1 or shown in Figure 2, the scale lid is made with channel-section steel (12) by double-layer plate, middle weldering.For prevent that the weighing object from skidding on panel (1), burn-on on it deformed bar or round bar are perhaps made of figuratum steel plate again.After cover panel makes, in its surrounding with α 〉=90 ° burn-on plate washer (13) and plate washer (13) hook (20).As Fig. 1 or shown in Figure 3, isolation damper mainly contains doughnut and cover tire (2), compression spring (3), the spring drum seat (4) that is full of gas, steel ring (15) and the rubbing board (14) of placing tire (2).Steel ring (15) is positioned at the middle part of tire (2), and with the fixing position of tire, steel ring (15) is welded in the center of anti-vibration and shock plate (5), and buffer board (5) and (5a) between be welded with channel-section steel (12a) as reinforcement.Spring drum seat (4) be evenly distributed on tire (2) around, put compression spring (3) in the middle of it, the bottom of same isolation damper makes of two-layered steel plates, use channel-section steel as reinforcement between the steel plate, the making of intermediate plate such as Fig. 4 and shown in Figure 5, at first make a surface plate (7) with steel plate, on it, be welded with n annulus (11) by stressing conditions, in each annulus (11), place steel ball (6), steel ball can freely roll in annulus, and its effect is the horizontal thrust that slows down the weighing object.On 4 angles of the bottom surface of surface plate (7), be welded with sensor pad (17), as the supporting-point of sensor, simultaneously at 4 arms of angle of surface plate (7) plate washer (18) of burn-oning vertically downward.Fig. 6 or Fig. 7 show the construction drawing of bedplate (10), same elder generation makes a surface plate to steel plate, on its 4 angles sensor backing plate (8) is housed, to make things convenient for the installation of sensor, simultaneously be welded with limiting plate (19), and circular hole (21a) is arranged on it at four arms of angle.
More than after four critical pieces carry out, bedplate is installed, diplopore bridge type magnetic sensor (9) is placed on the sensor base plate (8), simultaneously the signal output line is drawn.The position that intermediate plate is placed makes circular gasket (17) and sensor backing plate (8) just on same center line.Put steel ball (6) in annulus (11), whole isolation damper is placed on the intermediate plate, because steel ball (6) can freely roll in annulus (11), a little moves so isolation damper can be gone up work at steel ball (6).At last stalk is covered, the signal transmission line of sensor is connected the back just can come into operation.
Structure shown in this case also is its most preferred embodiment.
