Description

Technical Field

[0001] This utility model relates to the field of belt inspection, and in particular to a belt tear detection device based on iron ore aggregate processing. Background Technology

[0002] In the iron ore aggregate processing industry, belt conveyors, as key equipment for material transportation, undertake the continuous conveying task from the ore mining site to various processing stages such as crushing, screening, and grinding. Their operational stability directly affects the efficiency and safety of the entire production process. However, under long-term high loads and complex operating conditions, belt tearing accidents occur frequently. Once a belt tears, it not only leads to material leakage and production interruption, causing huge economic losses, but may also cause equipment failure and even endanger personnel safety.

[0003] However, existing belt detection devices often rely on monitoring belt tension changes to detect belt tears. They can only indirectly determine the tear condition through tension fluctuations. Normal operations such as load changes, start-stop, and elasticity changes caused by belt aging can all cause tension fluctuations, which can easily lead to misjudgments and make it difficult to accurately determine the specific location, length, width, and depth of the tear. Utility Model Content

[0004] To overcome the problem that existing belt detection devices mostly monitor belt tension changes during use, but belt start-up and shutdown, load changes during operation, or belt aging can all cause tension fluctuations, thus affecting the accuracy of the belt detection device.

[0005] The technical solution of this utility model is: a belt tear detection device based on iron ore aggregate processing, including a support assembly and a detection component connected to the support assembly;

[0006] The support assembly includes a fixed support connected to the detection assembly, a combined frame connected to the fixed support, a contact roller movably connected to the combined frame, and a pulley assembly connected to the fixed support.

[0007] The detection assembly includes a first fixed base and a second fixed base connected to a fixed bracket, a first line laser scanner connected to the first fixed base, and a second line laser scanner connected to the second fixed base.

[0008] Preferably, the first fixed seat and the second fixed seat are arranged symmetrically about the horizontal central axis of the fixed bracket, and a number of the combined frame are provided, and the number of the pulley assembly is set to twice the number of the combined frame.

[0009] Preferably, the pulley assembly includes a connecting frame connected to a fixed bracket, a roller frame connected to the connecting frame, and a connecting roller movably connected to the roller frame.

[0010] Preferably, the support assembly is connected to an impact component, which includes a support bar connected to the fixed support, a fixing rib connected to the support bar, a pushing component connected to the support bar, a guide plate connected to the pushing component, and a slag collection box connected to the guide plate.

[0011] Preferably, the pushing assembly includes a base bracket connected to the support bar, an impact bar movably connected to the base bracket, a hydraulic push rod connected to the impact bar, and a fixing bar connected to the hydraulic push rod.

[0012] Preferably, the impact assembly is connected to a scraping assembly, which includes a connecting rod connected to the base bracket, a servo motor connected to the connecting rod, and a slag removal assembly connected to the output shaft of the servo motor.

[0013] Preferably, the slag removal assembly includes a rotating rod connected to the output shaft of a servo motor, a rotating cylinder connected to the rotating rod, and a plurality of slag scrapers connected to the rotating cylinder.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses a first-line laser scanner and a second-line laser scanner to scan the height changes and continuous changes of the belt to measure the length, width, and height of the tear. The measured dimensional data is compared with a threshold to detect the tear state, thereby significantly improving the working efficiency of the entire belt tear detection device. This solves the problem that existing belt detection devices mostly monitor belt tension changes, but during belt use, belt start-up and shutdown, load changes during operation, or belt aging can all cause tension fluctuations, thus affecting the accuracy of the belt detection device.

[0016] 2. This utility model uses a hydraulic push rod to drive the impact bar to reciprocate in the vertical direction, and the impact bar impacts the belt, so that the slag adhering to the belt surface can be separated from the belt, thereby greatly improving the detection accuracy of the first-line laser scanner and the second-line laser scanner. The guide plate guides the slag impacted by the pushing component, so that it can fall from the guide plate and enter the slag collection box, thereby realizing the removal of large particles of slag adhering to the belt.

[0017] 3. This utility model uses a servo motor to drive the rotating rod to rotate, and the rotating rod drives the rotating cylinder to rotate. Several scraper blades connected to the rotating cylinder rotate to achieve secondary removal of slag that has not been impacted by the impact bar, thereby greatly improving the working efficiency of the entire belt tear detection device.
