Abstract

The invention discloses a verification device of static weight and superposition composite hook scale, which includes a baseboard, a pull up connector, a hook scale, a drop down connector and a center hanger. Two upright columns are installed in parallel on the baseboard. A supporting board is installed on the upright column. Two lead screws are installed in parallel on the supporting board. A fixed beam is installed on the top of the lead screw. A moving beam is installed between two lead screws. Standard transducers are installed on the moving beam from the left to the right. A weight pallet and several counterweights are installed vertically on the center hanger. A mechanism, which is used to release counterweights, is installed on the upright column. A link block is installed at the bottom of the center hanger. A hydro-cylinder is installed on the baseboard. A plunger is installed in the hydro-cylinder. The link block is located in the fluting groove of the plunger. The manufacturing cost of the verification device of static weight and superposition composite hook scale is low and the measuring range of the verification device of static weight and superposition composite hook scale is large.

Description

technical field [0001] The invention belongs to the technical field of electronic scale weighing, and in particular relates to a static weight and superposition composite hook scale verification device. Background technique [0002] At present, the devices used for the verification of hook scales at home and abroad are divided into the following categories according to the structure and principle: [0003] 1. Static weight type: the gravity of the weight is used as the standard load, and the load is automatically and steadily applied to the hook scale verification device of the checked hook scale automatically and smoothly in a predetermined order through an appropriate mechanism. The weight is both the force source and the weight. The force value is given, which is characterized by high precision and large range, but the manufacturing cost increases significantly with the increase of the range, and is mainly used for the detection of small-range hook scales.
