The utility model is composed of an upper hooking plate, a bearing plate, a display instrument plate, a sensor, a direct current power supply, a bottom plate, wheels, a lower hooking plate, a wireless remote-control receiver, etc. The utility model enables calibration and checking to have the advantages of simplicity, safety, reliability, time saving, labor saving and expenses saving under the condition that requirements on use accuracy are satisfied.
Description
The utility model relates to a kind of caliberating device that can use accuracy to carry out verification to the sky cart balance.
At present, the use of day cart balance is very extensive.But it but is the thing that bothers very much that verification is demarcated in the use accuracy of sky cart balance.Particularly some large-tonnage sky cart balances are all the more so, as 140t, and 200t, 350t or the like.At present, the sky cart balance is demarcated verification, mainly contain two kinds of methods, the one, demarcate verification with standard test weight, it cart balance is by hanging tens tons, so up to a hundred tons of counterweights demarcate verification, the 2nd, demarcate with substitute, some weight is transported to weighter for truck earlier or track scale gets on to weigh up weight, demarcate verification sky cart balance again.These methods all relatively waste time and energy and expensive, and unsafe factor is many, various in addition situations and condition different, and concerning some day cart balance, difficulty is a lot, very difficult especially to carry out once such demarcation.
The purpose of this utility model is: provide a kind of volume little, in light weight, its special calibrating calibration equipment of conveniently moving guaranteeing to satisfy under the situation of using accuracy requirement, replaces counterweight or substitute, and verification is demarcated in the use accuracy of sky cart balance.Under in conjunction with on-the-spot actual situation, make that to demarcate verification work simple, safety, reliable, save time, laborsaving and reduce expenses.And demarcation verification work is made a practice of.
The purpose of this utility model is achieved in that uses high-precision sensor as load-sensing unit, and sensor base is fixed on the base plate of suitable intensity.This base plate is sling by wire rope by overhead traveling crane.Hang over above the sensor with other steel cable cover, weight is removed to hang in two ends again.Along with the overhead traveling crane lifting, make sensor be in pressured state thus, suffered pressure is the weight of hanging object just.Size (being the weight of hanging object) by this pressure of sensor measurement shows numerical value by the display instrument dash board with digital form, and when hanging weight, a day cart balance also is to weigh, and indicating value is also arranged.Therefore two indicating values are compared, just can finish the demarcation verification work of sky cart balance.By suitable physical construction and assembling, except sensor and display instrument dash board, mix other corresponding parts again, just formed an isolated plant of demarcating verification.Specific as follows:
With a high precision force cell, be fixed on the base plate of suitable intensity.When the sensor pressurized is stressed, there is one to be directly proportional with the pressure size and linear electric signal output.
On base plate, be fixed with the display instrument dash board simultaneously.The electric signal of output was sent to the display instrument dash board when sensor was stressed.Demonstrate the stressed numerical value of sensor with digital form by the display instrument dash board.
Appropriate location below base plate is fixed with two channel-section steels, as the lower draw-bar plate, can hang wire rope.Like this, overhead traveling crane can be sling this base plate (together with the sensor instrument panel etc.) come by wire rope.
Hanger plate on fixedly connected one also is to be used to hang wire rope on sensor.Hung on this on hanger plate by other steel cable cover, weight is removed to hang in the wire rope two ends.Like this, along with the overhead traveling crane lifting, it is middle that sensor string is hung in, and is in pressured state, can carry out dynamometry.The suffered pressure of sensor is the weight of hanging object just.Under heavy weight situation, the employing sensor is that the mode of pressurized also compares safety.
Thus, just formed by overhead traveling crane and base plate (together with sensor instrument panel etc.) has been sling by wire rope, hang on the sensor by cover by another root wire rope weight is sling, the situation that sensor and day cart balance are measured hanging object simultaneously, two situations that measured value can be compared.
One direct current power supply (adopting 6 volts of batteries) is arranged, also be fixedly mounted on above the base plate, be sensor, display instrument dash board and other associated components provide operating voltage.
One wireless remote controlled receiver is arranged, be installed on the display instrument dash board.Reception, is carried out power supply and is opened and closed being hung in aerial display instrument dash board from manual operator, shows relevant control signals such as zero clearing.
Make shell with iron plate, seal into a rectangular parallelepiped casing.The about 650*250*250 of size (mm).There is handle that wheel is arranged on the casing, can lifts removable.Form the caliberating device of a special use thus.
During use,, hang over down on two lower draw-bar plates below the caliberating device base plate, hang and hung caliberating device at first with hanging on the steel cable on the overhead traveling crane suspension hook.With on the last hanger plate that hangs on another root wire rope above the caliberating device sensor, hang on the weight (or earth anchor) down again.Form overhead traveling crane and hang caliberating device, caliberating device is hung the series connection of weight (or earth anchor) and is hung form.
Then, a caliberating device and a day cart balance instrument are shown zero clearing simultaneously.
Next demarcate verification and begin, overhead traveling crane slowly lifts by crane, owing to be the mode that series connection is hung, therefore as long as operation crown block lifts by crane (no matter whether weight is sling), just acted on day cart balance and the caliberating device effectively, and size equates.Because strong effect, day cart balance and caliberating device instrument all can have weight to show.Like this, by suitable lifting operation, make day cart balance stressed be about respectively overhead traveling crane weighing journey 10%, 20%, one until 100%, at this moment caliberating device is puted forth effort too.Indicating value with sky cart balance and caliberating device compares then, just can demarcate verification.
Caliberating device is hung aloft, can be operated by the manual operator wireless remote control.
Owing to adopt such scheme, can make the demarcation verification work of overhead traveling crane scale convenient and simple, realize regular practice easily, thereby guarantee the actual use accuracy of day cart balance.Also can solve some day cart balance because of site environment, working condition, the demarcation verification difficulty that reasons such as equipment means cause.Use caliberating device to newly-built overhead traveling crane test mass, equally also be suitable for.The interim weighing device that also can be used as under some situation uses, and when overhead traveling crane is hung object, object is carried out Weighing.
