Abstract
The invention discloses a calibrating device for a weighing machine, which comprises a truck, a standard-weight box and a tower-type lever lifting machine, wherein the truck is a mini-truck; three baffles of container of the truck can be opened and turned to be hung on the container body; the standard-weight box is an uncovered cuboid; four round holes are respectively formed on the four side surfaces of the container body; and the tower-type lever lifting machine comprises a base, a vertical post, a lever-type hanger rod and a hook, and the lever-type hanger rod is assembled at the upper end of the vertical post through a rotary shaft. According to the calibrating device provided by the invention, mechanical transmission and hoisting are adopted, time and labor are saved, purposes of safety and reliability are achieved, the wear of the standard weight is avoided so as to prolong the detection period, and the detection precision is also improved.
Description
Technical field
The present invention relates to metering Instrument equipment, especially a kind of weighing instrument verification device.
Background technology
The calibrating maximum capacity is the counterweight of 25～50 20kg of weighing apparatus employing of 500～1000kg at present; Need be during use from the transport vehicle counterweight being removed one by one to the bearing plate of seized weighing apparatus; So the muscle power work is very heavy, and also the easy abrasion counterweight shortens its calibration interval, and influences calibration accuracy.
Summary of the invention
The technical matters that the present invention will solve provides a kind of simple and practical, convenient and strength-saving weighing instrument verification device.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: the weighing instrument verification device comprises goods vehicle, standard test weight case and tower lever hoisting machine; Goods vehicle is a minitruck, and three baffle plates of lorry container can be opened the upset hanging under casing; The standard test weight case is the uncovered rectangular parallelepiped, and respectively there is 1 circular hole the side around the casing; Tower lever hoisting machine is made up of base, column, lever suspension rod and suspension hook, and the lever suspension rod is assemblied in the column upper end through rotating shaft.
The standard test weight case has 5, and 4 20kg standard test weights are arranged in each standard test weight case, standard test weight case deadweight 20kg.
The long-armed lever ratio of the lever short arm of lever suspension rod and lever is 1:4, through wire rope rope 4 suspension hooks is arranged on the suspension ring of lever short arm end.
To current maximum capacity is the problem that 500～1000kg weighing instrument verification technology exists, and the inventor has designed weighing instrument verification device of the present invention, comprises goods vehicle, standard test weight case and tower lever hoisting machine.When going out to examine and determine weighing apparatus; Standard test weight case and tower lever hoisting machine that standard test weight is equipped with in 5 of goods vehicle shipments arrive the calibrating scene; Tower lever hoisting machine removed to land place correct position; Operate tower lever hoisting machine one by one handling standard test weight case that standard test weight is housed place on the bearing plate of seized weighing apparatus, examine and determine seized weighing apparatus by vertification regulation.
As everyone knows; Measurement verification must be carried out transmission of quantity value according to national measurement verification system table; Measurement instrument amount in the quality specialty passes in the system diagram; Common magnitude transferring method utilizes direct comparison method or combination relative method exactly, the counterweight transmission of quantity value of higher accuracy rating is given the counterweight of low accuracy rating by means of the standard balance of corresponding accuracy.Transmission method that uses the calibrating of this weighing instrument verification device and the conventional counterweight method that directly adds realize that the transmission to the weighing apparatus value is consistent.Science of the present invention is practical, has improved the defective of classic method, adopts mechanical transport, lifting, and is time saving and energy saving, safe and reliable, avoided the wearing and tearing of standard test weight, prolonged the calibration interval of standard test weight, also improved calibration accuracy.
Description of drawings
