Problems solved by technology

And due to the inconvenience of detection, when the gear is abnormal, it cannot be repaired and replaced in a timely and effective manner. This periodic inspection cannot ensure the safety of the gearbox. The effect is not ideal, and it brings considerable safety hazards
[0004]In actual production, due to the frequent lifting and frequent stops, and the long-term dynamic operation under high-intensity loads, the wear and tear on the internal components of the gearbox is very high, and due to The characteristic that the gearbox is a closed device brings great inconvenience to the inspectors during the inspection, and it is impossible to monitor the status of each component in the gearbox in real time. When the gears or bearings in the gearbox crack, it may happen Serious consequences of abnormal beating when the crane is running, what's more, it will cause the gear box to burn due to friction, and cause a major fire accident due to the adhesion of grease

Embodiment 1

[0053] In the daily inspection, the detector is used to detect the gearbox of the crane. After the excess air is discharged by the air pump, the crane is running and the gear set in the gearbox is running. The detector detects that the vibration wavelength in the gear box is between E and "h<E<H", so the feedback is normal.

Embodiment 2

[0055] In the daily inspection, the detector is used to detect the gearbox of the crane. After the excess air is discharged by the air pump, the crane is running and the gear set in the gearbox is running. The detector detects that the vibration wavelength E in the reduction box exceeds the set range value "h<E<H", and judges that the E wavelength is within the grade 1 mild range, then the recorder starts to record the detection time and status, and The green signal light is on at the computer terminal, warning the detection party to follow up and check the gearbox.

Embodiment 3

[0057] In the daily inspection, the detector is used to detect the gearbox of the crane. After the excess air is discharged by the air pump, the crane is running and the gear set in the gearbox is running. The detector detects that the vibration wavelength E in the gear box exceeds the set range value "h<E<H", and judges that the E wavelength has exceeded the range of level 3. When the red signal light is on, it warns the testing party that the gearbox needs to be stopped immediately for parts replacement and maintenance.

[0058] In order to check the state of the closed reducer of the crane in operation, the present invention overcomes the disadvantages of difficulty in checking the reducer and the inability to visually detect it, and uses a vibration collector to collect the vibration waves generated by the reducer during operation, and uses this as a basis The processing and judgment are carried out to assist the inspectors to effectively monitor the status of the reducer ...

Abstract

The invention discloses a portable closed gearbox detection device and an abnormality judgment method, relates to the field of hoisting machinery, and is used for real-time monitoring of the running state of a gear in a gearbox and early warning control when the gear abnormally deforms during dynamic running of a crane. The closed speed reducer of the crane is monitored at any time in a few-man and unmanned state according to current large hoisting equipment, so that the problem that the speed reducer of the crane is abnormal can be effectively solved in actual production, the hoisting safety operation rate is improved, abnormal accidents are prevented, the safety of production logistics is effectively controlled, and the effect of solving the production safety problem is achieved. According to the invention, any person can carry out inspection at any time without the assistance of the related professional inspection personnel, the common point inspection personnel can independently carry out operation, and the system has an intelligent judgment mechanism, can effectively judge the danger degree of related equipment, and is more intelligent and user-friendly.

Description

technical field [0001] The present invention relates to the field of hoisting machinery, and more specifically refers to a portable closed gear box detection device and an abnormality determination method, which are used for real-time monitoring of the running state of the gears in the gear box during the dynamic operation of the crane and detection of abnormal deformation of the gears. Early warning control. Background technique [0002] Any kind of moving mechanism (including translation mechanism and winch mechanism) in the hoisting machinery has basically the same structure, which belongs to the product of electromechanical integration. Taking the translational motion mechanism as an example, the fast shaft derived from the motor is connected to the reduction box (also called gearbox) through the brake to change the torque, drives the slow shaft, and connects to the corresponding driving wheel to make it run. The role of the gearbox is to reduce the speed and increase t...
