The manhole cover performance test equipmentdisclosed by the invention is rapid test equipment designed by virtue of tool-hydraulic combination, PLC control, liquid crystal display screen visualization and assembly, simulates the actual serviceenvironment, is good in flexibility as well as accurate and visual in data and fills in the blank of the type of equipment in the industry.
Description
technical field [0001] The invention belongs to the technical field of manhole covers, in particular to a performance testing device for manhole covers. Background technique [0002] The traditional manhole cover function test is done by clamping the product on the tooling. All valves that need to be operated must be operated in sequence. The test time needs to be memorized by watching the clock stopwatch, and the test data cannot be recorded during the test. The manhole cover performance test is all manual operation, which is prone to errors, high labor intensity, low efficiency, inconvenient and error-prone test data observation. [0003] In summary, the existing manhole cover function test mainly has the following defects: [0004] 1) The traditional press plate tooling is inconvenient to install, the uniformity is not good, and the workers have high technical requirements; [0005] 2) Poor control stability of traditional electrical appliances; [0006] 3) Human obser...
