Description

Technical Field

[0001] The invention relates to the technical field of belt scale maintenance, and in particular to a belt scale chain code calibration auxiliary tooling, and a belt scale chain code calibration construction process using the tooling. Background Art

[0002] As the cumulative running time increases, the various parts of the belt scale will wear out to varying degrees, which will affect the weighing accuracy. Therefore, the belt scale needs to be calibrated regularly to ensure its measurement accuracy and reliability. At present, when calibrating the belt scale, most of them still use manual lifting and pulling, which is indeed simple and easy to calibrate the belt scale in general locations.

[0003] However, the sintering and coke oven areas of the steel plant are equipped with a large number of belt scales, and due to the large temperature changes in the working environment, the belt scales in these areas need to be calibrated once a month; at the same time, each calibration operation requires the chain code, which is about 2 meters long and weighs about 100 kg, to be placed on the weighing section from the conveyor belt box mouth, and the working height can reach up to 4.5 meters. At this time, if manual handling and lifting are still used, the labor load is heavy, the working efficiency is low, and there is also a safety risk of the chain code falling from a high altitude and injuring people.

[0004] However, there is no chain code lifting and handling equipment on the market that meets the working environment of steel mills. Therefore, it is urgent to design and manufacture a belt scale chain code calibration auxiliary tooling to reduce labor and improve efficiency. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a belt scale chain code calibration auxiliary tooling and construction process that can realize the mechanized retraction, release and transportation of the chain code.

[0006] The present invention adopts the following technical solution:
