Abstract
The utility model belongs to a weighing device, in particular to an automatic counting mechanism used for the speed measurement and the height measurement weighing supplementation of a gantry cane grab bucket electronic loadcell scale. The automatic counting mechanism comprises a counter bracket, a magnetic control head and a magnetic block arranged on the top part of a shaft block and on the circular end surface of main and auxiliary hook winding drums. The automatic counting mechanism solves the problems of the prior art of the counting misalignment and great repeated error caused by poor counting consistency due to the changes in the lifting speed and the hoisting height when the gantry crane works, and has accurate, rapid, stable and reliable counting when matched with a grab bucket electronic loadcell scale, saves the cost expense for a harbor, and improves the work efficiency and the economic benefit of a loading and unloading ship.
Description
Technical field
The utility model belongs to meausring apparatus, is meant that especially a kind of machine grab bucket electronic scales that is used for tests the speed, surveys the automatic counting mechanism of high weighing compensation.
Background technology
The patent No. is in 200720100801.0 the utility model patent, disclose a kind of Weighing mechanism of improved grab type electronic scales, comprised the flat sensor of the major and minor hook reel transmission shaft other end axle supporting base centre that is installed on the crane in bridge type crane carriage and be connected in series the stacked holistic weighting apparatus that is respectively with bearing seat, supporting base with its upper and lower surface.Above-mentioned prior art is applied on the high pedestal jib crane of harbour, metering misalignment and the great shortcoming of repeatability error that the metering conformability difference that a machine that exists causes because of situations such as lifting velocity variation and lifting height change when operation is caused.
Summary of the invention
The purpose of this utility model is to provide the numerical measuring of a kind of rising of grabbing bucket, the velocity measurement that descends and grab bucket rising, falling head and a machine grab bucket electronic scales that is used for of highly weighing compensation to test the speed, survey the automatic counting mechanism that high weighing compensates.
Overall technology design of the present utility model is:
Be used for machine grab bucket electronic scales and test the speed, survey the automatic counting mechanism of high weighing compensation, comprise on the circular end surface 19 that is installed on major and minor hook reel 1,2 and counter-support 20,21, magnetic control head 22,23 and the magnet piece 24 at bearing seat 3,4 tops.
Concrete technical construction of the present utility model also has:
Wherein counter-support and the preferred fit of magnetic control head are:
Principle of work of the present utility model is as follows:
When major- minor cable drum 1,2 anticlockwise directions rotate, the grab bucket load is upwards promoted by low side, acceleration due to gravity of loading in the process that grab bucket is risen and steel rope all are variablees through friction force that a plurality of pulley produced etc., these variablees should be distinguished and be rejected with the true value of grab bucket load, can draw the actual weight value of grab bucket load.By being installed in major- minor cable drum 1,2 with bearing seat 3, on 4 the two contactless automatic counting mechanism of cover just can automatically detect the speed that 2 steel ropes rise, and determine the residing height and position of grab bucket load by counting machine, thereby can output to and calculating the friction force that the acceleration due to gravity that produced when grab bucket load rises and each bar steel rope are produced in the control setup, in the decline process, the gross weight of grab bucket and steel rope generation is removed the peel the heavily low side zero setting point position height L of (zero setting) after can accurately determining the high-end sampling point position height H of grab bucket load and determine the grab bucket blowing by count value simultaneously, H, the L point is in case selected, in whole grab bucket operation process, the automatic counting mechanism of this two cover just can carry out autocontrol operation by main program.Because related display instrument and the circuit of this control setup is routine techniques, do not repeat them here.
The obtained technological advance of the utility model is:
The utility model has solved gate seat that prior art exists and has been hung in the operation of stevedoring ship grab bucket in different gears (speed), caused weighing numerical value instability under the randomness operational circumstances that rises or descend, the technical barrier that inconsistent gross error and repeatability error are big, supporting grab bucket electronic scales uses to numerous domestic harbour general-duty high pedestal jib crane and has set up an accurate measurement, rapid and reliable and stable Weighing equipment, a large amount of manpowers that the loading and unloading ship time uses many heavy-load automobiles and large-tonnage weighbridge to be paid in order to the gross weight value that could determine the loading and unloading ship after large bulk cargo being carried out Weighing and transporting have been saved, material resources and expense, save the cost expenditure for the harbour, improved the work efficiency and the economic benefit of loading and unloading ships.
Description of drawings
Accompanying drawing of the present utility model has:
Fig. 1 is an integral structure scheme drawing of the present utility model.
Fig. 2 is that the utility model is assemblied in the structural representation on the machine grab bucket scale.
