[0024] Please see Figure 1-4An elevator guide rail surface flatness detection device includes an elevator guide rail 1, a fixing device 2 for fixing the elevator guide rail 1 on the front side wall, a sliding device 3 for providing sliding support on the opposite side wall of the fixing device 2, a front grinding device 4 for grinding the front side wall of the elevator guide rail 1 inside the sliding device 3, and a side grinding device 5 for grinding both sides of the elevator guide rail 1 inside the front grinding device 4.
[0025] Specifically, the elevator guide rail 1 is first calibrated using an elevator calibration ruler. When the joint of the elevator guide rail 1 needs to be ground and calibrated, the fixing device 2 is fixed at the upper and lower ends of the joint of the elevator guide rail 1. The front grinding device 4 in the sliding device 3 grinds the front side wall of the joint of the elevator guide rail 1. The front grinding device 4 drives the two side grinding devices 5 to grind the left and right side walls of the joint of the elevator guide rail 1. This improves the efficiency of grinding and calibrating the joint of the elevator guide rail 1 and reduces the difficulty of operation, making it easier for calibration personnel to use.
[0026] The fixing device 2 includes a fixing seat 201, a sliding clamp 202, a screw 203 and a rotating wheel 204. The fixing seat 201 is installed on the front side wall of the elevator guide rail 1.

The rotating wheel 204 is fixedly installed on the right side wall of the screw 203.
[0027] Specifically, the fixed seat 201 is placed at the upper and lower ends of the joint of the elevator guide rail 1. Then, the rotating wheel 204 drives the screw 203 to rotate, thereby causing the screw 203 to move the sliding clamp 202 within the fixed seat 201, thus clamping and fixing the elevator guide rail 1 through the fixed seat 201 and the sliding clamp 202.
[0028] The sliding device 3 includes a sliding seat 301 and a slider 302. The sliding seat 301 is fixedly installed on the opposite side wall of the fixed seat 201, and the slider 302 is slidably installed inside the sliding seat 301.
[0029] Specifically, the slider 302 slides within the sliding seat 301, thereby enabling the front grinding device 4 to move up and down.
[0030] The front grinding device 4 includes a grinding base 401, a grinding plate 402, a limiting rod 403, and a push handle 404. The grinding base 401 is fixedly installed on the rear side wall of the slider 302, and the grinding plate 402 is fixedly installed on the rear side wall of the grinding base 401. Fixing holes are provided on the left and right side walls of the grinding base 401 and the grinding plate 402. The limiting rod 403 is installed in the fixing holes of the grinding base 401 and the grinding plate 402. The push handle 404 is fixedly installed on the front side wall of the grinding base 401. The front grinding device 4 includes a connecting seat 405 and a connecting seat 406. The connecting seat 405 is fixedly installed on the left and right side walls of the grinding base 401, and the connecting seat 406 is fixedly installed on the left and right side walls of the grinding base 401.
[0031] Specifically, by pushing the handle 404, the grinding base 401 is driven to slide up and down, thereby the grinding base 401 drives the grinding plate 402 to grind and correct the front side wall of the elevator guide rail 1. The grinding plate 402 is limited within the grinding base 401 by the limiting rod 403, so that when the grinding plate 402 is worn, it can be replaced. The connecting seat 405 and the connecting seat 406 provide stable support for the grinding devices 5 on both sides.
[0032] The two-sided grinding device 5 includes a second grinding base 501, a second grinding plate 502, and a second limiting rod 503. The second grinding base 501 is fixedly installed on the rear side wall of the first connecting seat 405 and the second connecting seat 406. The second grinding plate 502 is fixedly installed on the opposite side wall of the second grinding base 501. Fixing holes are opened inside the second grinding base 501 and the second grinding plate 502. The second limiting rod 503 is installed in the fixing holes of the second grinding base 501 and the second grinding plate 502.
[0033] Specifically, the grinding base 401 drives the connecting seat 405 and the connecting seat 406 to slide, thereby driving the grinding base 501 and the grinding plate 502 to grind and correct the left and right side walls of the elevator guide rail 1.
[0034] In summary:
[0035] First, the elevator guide rail 1 is calibrated using an elevator calibration ruler. When grinding and calibrating the joint of the elevator guide rail 1 is required, the fixing device 2 is fixed at the upper and lower ends of the joint of the elevator guide rail 1. The front grinding device 4 in the sliding device 3 grinds the front side wall of the joint of the elevator guide rail 1. The front grinding device 4 drives the two side grinding devices 5 to grind the left and right side walls of the joint of the elevator guide rail 1, thereby improving the efficiency of grinding and calibrating the joint of the elevator guide rail 1 and reducing the difficulty of operation, making it easier for calibration personnel to use. The fixing seat 201 is placed at the upper and lower ends of the joint of the elevator guide rail 1. Then, the rotating wheel 204 drives the screw 203 to rotate, thereby the screw 203 drives the sliding clamp 202 to move within the fixing seat 201. Thus, the fixing seat 201 and the sliding clamp 202 move within the fixing seat 201. 2. The elevator guide rail 1 is clamped and fixed. The slider 302 slides within the sliding seat 301, allowing the front grinding device 4 to move up and down. The handle 404 is pushed to drive the grinding base 401 to slide up and down, thereby driving the grinding plate 402 to grind and correct the front side wall of the elevator guide rail 1. The limiting rod 403 limits the grinding plate 402 within the grinding base 401, so that it can be replaced when it is worn. The connecting seat 405 and the connecting seat 406 provide stable support for the grinding devices 5 on both sides. The grinding base 401 drives the connecting seat 405 and the connecting seat 406 to slide, thereby driving the grinding base 501 and the grinding plate 502 to grind and correct the left and right side walls of the elevator guide rail 1.
