Abstract
The invention relates to a concave weight with a great deal limit, which is a mass measure standard implement .It is a whole that made of concave weight substance, branch leg and support through casting or welding, it self is a standard implement, and a number of small mass weight can be combined into a group of five-ton weight .The invention is mainly used in the test large and medium-sized weighing apparatus using weight-detecting machine to increase testing efficiency.
Description
Technical field
The present invention relates to a kind of quality standard device one counterweight, this invention is a standard, can load other counterweight again.The appearance structure of counterweight has been realized its dual-use function.
Background technology
Present weighing instrument verification department in each quality supervision mechanism of China, employed counterweight in weighing instrument verification work, handled every the quality that is to use the requirement of JJG99-1990 national metrological verification regulations more than 80 percent is 20 kilograms a counterweight, and also having seldom, unit uses handled parallelepiped-shaped and cylindrical 1000 kilograms of large quantity limit weights that guidance tape is arranged in the OIML.IR47 international recommendation.
Summary of the invention
It is 1 ton that task of the present invention is to provide a kind of quality, is shaped as the large quantity limit weight of matrix, and its counterweight is a standard test weight, several little quality weight groups can be combined into simultaneously one group of quality again and be 5 tons counterweight, in order to improve the work efficiency in the weighing instrument verification.
Technical scheme
The lower plane of this matrix counterweight is shaped on 4 supporting legs, and in order to support the weight of counterweight itself and institute's combination counterweight, its end of matrix counterweight is a plane, is shaped on support on the plane, and there is the chamber of adjustment screw the side of counterweight body.
Social benefit and economic benefit
Every existing quality of China is 20 kilograms a counterweight, when doing weighing instrument verification mainly is to extract with artificial, and be tens tons weighing apparatus to the table scale amount of examining and determine, there is manpower that tens of tons of counterweight taking off repeatedly, storing and position are moved, labour intensity is heavy.The current cylindrical counterweight that also has minority unit to use 1000 kilograms every tape guide band uses weigh bridge test car or other machinery, and a machinery also can only move a counterweight at every turn, inefficiency, and plant factor is low.This invention is that itself is 5 tons a counterweight except that doing standard test weight uses, can simultaneously several weight groups being combined into one group of quality again.This makes that when doing the weighing apparatus measurement verification weigh bridge test car once can extract or move 5 tons counterweight, increases work efficiency more than 5 times.
As to make every quality be 5 tons counterweight, also can increase work efficiency.Yet the balance that can examine and determine 5 Ton-level weights owing to China is few, if use 5 tonnes counterweight, the periodic calibration of these counterweights will be very difficult.Simultaneously quality inspection organizations at different levels are as purchasing 5 Ton-level weights, and the counterweight of original 20 kilograms and 1000 kilograms will be by idle, and this does not meet the national conditions of China economically.The concave large quantity limit weight working of an invention had both improved work efficiency, to original counterweight of each quality testing department, because all there are the detection capability to 20 feather weight counterweights, calibrating and the trucking costs that can save large quantity limit weight in its mechanism self; The 20 feather weight counterweights that quality testing department uses are for many years always utilized, and have reduced new input, can be country and save substantial contribution.
Description of drawings
Accompanying drawing is structure form figure of the present invention.
In the drawings, 1 supporting leg, 2 matrix counterweight bodies, 3 supports, 4 are adjusted the chamber screw.
Embodiment
In conjunction with the accompanying drawings specific embodiments of the present invention is explained.
As shown in the figure, matrix counterweight body (2) makes it to become an integral body with supporting leg (1), support (3) by casting or welding, and the chamber screw (4) of adjustment is arranged in the side of matrix counterweight body (2).
Claims (1)
1. concave large quantity limit weight, this counterweight is a kind of standard with existing counterweight equally, supporting leg, matrix counterweight body, support, adjustment chamber screw are arranged on the structure, it is characterized in that, its external form is different from the cylindrical of the parallelepiped-shaped of existing counterweight or tape guide band, and its shape is a kind of concave large quantity limit weight that has supporting leg, matrix counterweight body, support, adjustment chamber screw to constitute.
