Description

Technical Field

[0001] The utility model relates to the technical field of material hoist testing, in particular to full-load testing equipment for a material hoist. Background Art

[0002] The material hoist test equipment is used to test the full-load performance of mast-type material hoists. Existing material hoists use a manual capstan to rotate the hoist. However, due to limited human effort, the full-load test is not possible with a full-load test. Therefore, existing technology typically uses a half-load test method.

[0003] Moreover, with the existing manual drive method, it takes at least 40 minutes to test a material machine at half load (three lifts at full load). When the half load mass is 160kg, one operator cannot lift the material machine to a height of 7.5m in a short period of time. Two people may even need to take turns to recover their strength before operating again. On the other hand, since at least two people are required to test the material machine, a great waste of manpower occurs, resulting in disrupted production rhythm and low production efficiency.

[0004] In addition, this technical solution has the following deficiencies: it can only test the operating state of the material hoist at half load of 160kg, and cannot meet the requirements for testing the operating state of the full load of 454kg. It cannot fully verify the full load performance of the material hoist, and quality problems under full load may be concealed. The reason is: the performance of the material hoist at half load is different from that at full load. The quality performance of the load-bearing part and the lifting part of the material hoist changes according to the change of the loaded mass. Therefore, half-load operation cannot replace full-load operation. As a result, the half-load test solution cannot reflect the operating state of the material hoist under full load, and it is easy to miss quality problems.

[0005] In order to meet the requirements of full load test of material hoist and thus improve its safety, it is of great significance to study an efficient full load test equipment for material hoist. Utility Model Content
