Problems solved by technology

[0006] 1. Due to the large horizontal force required to suspend the chain code, this force directly acts on the drive rod, so the required drive rod specification is also relatively large
[0007] 2. Manufacturing lifting trolleys and curved trolley guide rails requires a large investment, and the production cycle is also long
[0008] 3. Since the driving rod is installed on the outside of the closed-loop chain code, the overall length of the equipment is longer
Not only consume more manufacturing costs, but also take up more space

Abstract

The lifting mechanism for circular chain code calibrating apparatus used in the calibration of electronic belt weigher includes frame beam, lifting bogie, circular chain code and driving lever. The lifting bogie and the driving lever are located on inner side the circular chain code; the lifting bogie has triangular frame; the frame beam has one oscillating rod with fixed end hinged to the frame beam and the oscillating end hinged to one link rod as well as chain code guide wheels set on two ends. The lifting mechanism has small occupied space, simple structure, reasonable stress and low cost.

Description

technical field [0001] The invention relates to a bulk material metering device, in particular to a lifting mechanism of a circular chain code verification device used for electronic belt scale verification. Background technique [0002] As we all know, belt conveyors are widely used for short-distance transportation of bulk bulk materials (such as coal, ore, etc.). Electronic belt scales are widely used in the measurement of material quality during the transportation process, and the accuracy of electronic belt scales needs to be checked regularly. [0003] The "Electronic Belt Scale Circular Chain Code Simulated Object Verification Device" (hereinafter referred to as "the verification device") is a special device for simulating the physical verification of the electronic belt scale. Such as figure 1 As shown, this equipment mainly consists of frame girder 1 (several rollers are arranged on it); cyclic chain code 6 (closed-loop chain formed by serial connection of code bl...
