The upper end of the first screw rod 1.6 extends above the support frame 1.1 and is fixedly connected to a first runner 1.7. Rotating the first runner 1.7 can drive the first screw rod 1.6 to rotate. When the first screw rod 1.6 rotates, the slider 1.3 threadedly connected thereto can drive the brush roller 1.4 and the other slider 1.3 to move up and down, adjusting the brush roller 1.4 to an appropriate height to suit outer covers of various thicknesses. A housing 1.8 is also fixedly connected to the frame 1. A correction assembly 2 is provided on the housing 1.8. A dust suction assembly 3 is also provided on the support frame 1.1.

When the outer cover passes between the two moving plates 2.2, the correction wheel 2.6 will block and correct the skewed part of the outer cover, avoiding the situation of skewed outer covers and improving the detection effect.

[0024] Specifically, as Figure 1 and Figure 3As shown in the figure, a defect detection device for the outer covering of an escalator. The dust suction component 3 includes an air inlet hood 3.1, a box body 3.2, a fan 3.3 and an adsorption filter plate 3.4. The air inlet hood 3.1 is fixedly connected to the upper inner wall of the support frame 1.1. The box body 3.2 and the fan 3.3 are also arranged on the upper outer wall of the support frame 1.1. The air inlet end of the fan 3.3 is connected to the box body 3.2 through a pipeline. The box body 3.2 is connected to the air inlet hood 3.1. The adsorption filter plate 3.4 is arranged inside the box body 3.2. Under the action of the fan 3.3, the impurities cleaned by the brush roller 1.4 will enter the box body 3.2 through the air inlet hood 3.1 and then be adsorbed by the adsorption filter plate 3.4. The air after adsorption will be discharged through the fan 3.3, effectively avoiding the influence of impurities on the outer covering surface on the detection accuracy.

[0025] Specifically, as Figure 4 As shown in the figure, a defect detection device for the outer covering of an escalator. A detection camera 1.81 is installed at the center of the upper inner wall of the housing 1.8, and lighting lamps 1.82 are arranged on both sides of the detection camera 1.81. The detection camera 1.81 is used to detect the surface of the outer covering, and the lighting lamps 1.82 can provide lighting when the environment is dim to ensure the detection effect.

[0027] Specifically, as Figure 3 As shown in the figure, a defect detection device for the outer covering of an escalator. Guide rails 3.41 are fixedly connected to both side walls of the adsorption filter plate 3.4. Positioning sliding grooves 3.21 adapted to the guide rails 3.41 are respectively formed on both inner walls of the box body 3.2. When the adsorption filter plate 3.4 needs to be cleaned, the adsorption filter plate 3.4 can be pulled out from the box body 3.2, and the adsorption filter plate 3.4 can be removed after the guide rails 3.41 are disengaged from the positioning sliding grooves 3.21.

[0028] When the present utility model is specifically implemented, rotating the first runner 1.7 can drive the first screw rod 1.6 to rotate. When the first screw rod 1.6 rotates, the slider 1.3 threadedly connected thereto can drive the brush roller 1.4 and another slider 1.3 to move up and down, adjusting the brush roller 1.4 to an appropriate height to adapt to outer covers of various thicknesses. Then, rotating the second runner 2.3 drives the second screw rod 2.1 to rotate. When the second screw rod 2.1 rotates, it will push the moving plate 2.2 towards the conveying mechanism 4 to adjust the distance between the two moving plates 2.2 according to the specifications of the outer cover. The output shaft of the motor 1.5 can drive the brush roller 1.4 to rotate. When the brush roller 1.4 rotates, it can clean the surface of the outer cover during conveyance. Under the action of the blower 3.3, the impurities cleaned off will enter the box body 3.2 through the air inlet cover 3.1 and then be adsorbed by the adsorption filter plate 3.4. The air after adsorption is then discharged through the blower 3.3, effectively preventing impurities from remaining on the surface of the outer cover and affecting the detection accuracy. When the outer cover after cleaning passes between the two moving plates 2.2, the correction wheel 2.6 will block and correct the skewed part of the outer cover to avoid the situation of the outer cover being skewed and improve the detection effect. When the outer cover passes through the housing 1.8, the detection camera 1.81 detects the surface of the outer cover and transmits the image to the computer.
