Combined vibration measurement auxiliary rod

Abstract

The invention provides a combined vibration measurement auxiliary rod, which comprises a sensor fixed hub, a small supporting seat, a large supporting seat, a connecting rod joint, connecting rods, and an accessory joint. The sensor fixed hub is movably arranged on the small supporting seat. The small supporting seat is movably arranged on the large supporting seat. The structure of the connecting rod joint is in the shape of a Chinese character zhong. The upper and lower ends of the connecting rod joint are respectively connected with the large supporting seat and the connecting rods. The lower end of the connecting rod joint is provided with the accessory joint. The accessory joint can be provided with a wide variety of accessories. An auxiliary rod can be provided with multiple connecting rods according to usage length requirements. The combined vibration measurement auxiliary rod is reasonable in structural design, low in manufacturing cost and strong in practicality.

Description

technical field [0001] The invention relates to the field of mechanical measurement, in particular to a combined vibration measurement auxiliary rod. Background technique [0002] With the widespread popularization of mechanical equipment in our country, many equipments need to manually measure the vibration of bearings and bearing bushes during testing and even work, and monitor the operation of equipment in real time, so as to detect bearing damage, bearing oil shortage, loose bolts, and coupling alignment in advance Defects, coupling damage and other defects, eliminate hidden dangers in time, and ensure the stable operation of equipment and production. Existing vibration measuring instruments are usually composed of spectrum analyzers, spiral data lines, sensors, magnetic bases, etc. When measuring vibration, it is necessary to manually place the sensor and magnetic base of the vibration measuring instrument on the vibration measurement point, and the vibration value is p...

Problems solved by technology

However, in the actual process of manual vibration measurement, the vertical direction, horizontal direction, axial direction, etc. of the bearing housing are measured, and the measurement points are often very close to the high-speed rotating shaft or coupling. These high-speed rotating equipment are only a punch away, which can easily cause damage to the rotating machinery; when measuring, the human body is less than half an arm away from the shaft seal of the equipment, such a close distance can easily cause leakage damage, such as when dealing with toxic gases or high-temperature gases When performing vibration measurement on high-risk conveying equipment, if the shaft seal of the pressurized equipment leaks, it is very easy to cause poisoning or burns to the measurement personnel; and the measurement points of some equipment are relatively high, and it is often necessary to climb during the placement of the sensor and the measurement process. operation, it is easy to cause falls or other mechanical injuries
