5results about How to "Avoid low detection accuracy" patented technology

The utility model provides a road test detection device for pavement deflection detection, and relates to the technical field of pavement deflection detection, the road test detection device comprises a frame body and a measuring assembly, the frame body comprises a connecting frame A and a connecting frame B, and gradienters are fixed on the connecting frame A and the connecting frame B. According to the road test detection device for pavement deflection detection, the connecting frame A and the connecting frame B can be in threaded connection together through cooperation of the threaded sleeve and the first threaded rod, higher fixing stability is provided through threaded connection, the situation that the detection precision is reduced due to the fact that the sliding fit clearance is too large or too small is avoided, mounting and dismounting are convenient, and the practicability is high. And a second threaded rod can be screwed into a storage threaded hole by rotating a fixed column, so that storage of the connecting frame A, the connecting frame B, the second threaded rod, the fixed column, a third threaded rod and the bottom plate is realized, the storage design of the device is optimized, and the storage convenience is improved.

This invention relates to the technical field of bending resistance testing, and discloses a method for testing the bending strength of power pipes. The method includes: inserting the support structures of a first clamping assembly and a second clamping assembly into both ends of the power pipe, and driving a cylinder of the support structure to perform a step-by-step progressive clamping process to clamp the power pipe; driving a compression assembly to apply pressure to the power pipe; and when the power pipe reaches a bent state, using the current pressure value of the compression assembly as the bending strength value of the power pipe. This invention's method for testing the bending strength of power pipes decomposes the clamping process by introducing a step-by-step progressive clamping process, avoiding overload and pre-stress introduction caused by continuous forced expansion, which would lead to a decrease in testing accuracy.

In the utility model, scraper sleeve is fixed to the bottom of anchor type rotor, hydraulic rod drives probe to retract, scraper sleeve bottom scrapes off adherend when probe retracts, avoid the surface of temperature sensor to be adhered by material, avoid causing measurement lag, effectively keep the accurate measurement of temperature.

This utility model relates to the field of safety protection light curtain technology, and specifically discloses a safety protection light curtain for automated equipment. The light curtain includes a monitoring component comprising a substrate, an accelerometer, and a buzzer. The outer surface of the protective cover has several through holes for real-time acquisition of triaxial vibration acceleration data. The system has a preset vibration threshold. When the number of times the vibration acceleration in any axis exceeds the threshold reaches a set value, it is immediately determined that the safety light curtain has a loose installation or displacement fault. At this time, the accelerometer immediately outputs a high-level signal to the buzzer, triggering the buzzer to emit a continuous alarm, reminding on-site personnel to check for potential hazards and avoid a decrease in detection accuracy due to accumulated offset. This effectively avoids the risk of safety protection failure due to safety light curtain offset, providing more reliable safety protection for operators and equipment operation, and significantly reducing the probability of mechanical injury accidents.
