[0002] Elevator guide rails are a crucial part of the elevator system. They mainly consist of steel rails and connecting plates and are divided into car guide rails and counterweight guide rails. From the cross-sectional shape, elevator guide rails can be divided into three forms: T-shaped, L-shaped, and hollow. Elevator guide rails provide precise guidance for the elevator car and counterweight device, ensuring that they move up and down along a predetermined path in the hoistway. The guide rails not only play a guiding role but also bear the impact force of the elevator car, counterweight device, and elevator braking. In case of an emergency, such as elevator overspeed or out-of-control, the guide rails can limit the abnormal movement of the car and serve as the last line of defense for safety.

[0022] Embodiment:

[0023] Referring to Figures 1 to 4 , an elevator guide rail cutting device according to an embodiment of the present utility model includes a support column 1. A cutting platform 2 is fixedly connected to the upper side of the support column 1. A cutting groove 7 is provided in the middle of the upper wall of the cutting platform 2. A T-shaped chute 4 is provided in the middle of the upper wall of the cutting platform 2. A fixing mechanism 3 is slidably connected inside the T-shaped chute 4. A cutting mechanism 6 is fixedly connected to the middle of the upper side of the cutting platform 2. A support plate 8 is fixedly connected to the upper wall on the left side of the cutting platform 2. A positioning mechanism 5 is movably connected to the middle of the upper side of the cutting platform 2. The elevator guide rail is fixed on the fixing mechanism 3, and the fixing mechanism 3 is pushed to move forward in the T-shaped chute 4 on the cutting platform 2 until it is fixed by the positioning mechanism 5. Then, the cutting mechanism 6 is turned on. The cutting groove 7 ensures that the cutting platform 2 will not be cut during cutting, and the support plate 8 reduces the shaking during cutting.

[0024] The fixing mechanism 3 includes a T-shaped slider 301, a mounting platform 302, a fixing rod 303, a rotating handle 304, a mounting protrusion 305, a threaded rod 306, and a fixing plate 307. The T-shaped slider 301 is slidably connected inside the T-shaped chute 4. The mounting platform 302 is fixedly connected to the upper side of the T-shaped slider 301. The fixing rods 303 are fixedly connected to the front ends of the left and right sides of the mounting platform 302. The mounting protrusions 305 are fixedly connected to the left and right sides of the mounting platform 302. The threaded rod 306 is threadedly connected to the middle of the mounting platform 302. The rotating handle 304 is fixedly connected to the outer end of the threaded rod 306. The fixing plate 307 is fixedly connected to the inner end of the threaded rod 306. The sliding of the T-shaped slider 301 in the T-shaped chute 4 makes the sliding more stable. When the rotating handle 304 is rotated, the threaded rod 306 rotates accordingly, pushing the fixing plate 307 forward to fix the elevator guide rail. The fixing rods 303 position the cutting position so that the elevator guide rail does not shake during cutting.

[0025] The positioning mechanism 5 includes a retraction groove 501, a through hole 502, a limiting plate 503, a connecting rod 504, an arc-shaped fixing block 505, a spring 506, and a fixing protrusion 507. The retraction groove 501 is arranged in the middle of the upper side of the cutting platform 2. The through hole 502 is arranged in the middle of the bottom of the retraction groove 501. The connecting rod 504 is slidably connected inside the through hole 502. The limiting plate 503 is fixedly connected to the bottom end of the connecting rod 504. The arc-shaped fixing block 505 is fixedly connected to the upper end of the connecting rod 504. The spring 506 is installed on the outer wall of the connecting rod 504. The arc-shaped fixing block 505 is slidably connected inside the retraction groove 501. When the fixing rod 303 moves forward, it presses the arc-shaped position of the arc-shaped fixing block 505 to make it descend and retract into the retraction groove 501. After the fixing rod 303 passes, the spring 506 raises the arc-shaped fixing block 505 again, and together with the fixing protrusion 507, restricts the fixing rod 303. The limiting plate 503 prevents the arc-shaped fixing block 505 from detaching under the action of the spring 506.

[0026] The cutting mechanism 6 includes a mounting frame 601, a hydraulic rod 602, a cutting motor 603, a rotating rod 604, and a cutting tool 605. The mounting frame 601 is fixedly connected to the middle of the upper side of the cutting platform 2. The hydraulic rod 602 is fixedly connected to the middle of the upper side plate of the mounting frame 601. The cutting motor 603 is fixedly connected to the telescopic end of the hydraulic rod 602. The rotating rod 604 is fixedly connected to the output end of the cutting motor 603. The cutting tool 605 is fixedly connected to the front end of the rotating rod 604. When the cutting motor 603 is turned on, the cutting motor 603 drives the rotating rod 604 to rotate, and the cutting tool 605 rotates accordingly. Finally, the hydraulic rod 602 is activated to make the cutting tool 605 cut the elevator guide rail downward.

[0027] Working principle: When in use, first place the elevator guide rail on the installation platform 302, align the cutting position with the front edge of the installation platform 302, and then rotate the rotary handle 304, causing the threaded rod 306 to rotate accordingly, pushing the fixed plate 307 forward to fix the elevator guide rail. Then push the fixing mechanism 3, where the T-shaped slider 301 slides in the T-shaped chute 4 to make the sliding more stable. As the fixing rod 303 moves forward, the fixing rod 303 presses on the arc position of the arc-shaped fixing block 505, causing it to descend and retract into the retraction groove 501. After the fixing rod 303 passes through the arc-shaped fixing block 505, the compressed spring 506 raises the arc-shaped fixing block 505 again, restricting the fixing rod 303 together with the fixing protrusion 507, so that the limiting plate 503 aligns the cutting position of the elevator guide rail with the lower part of the cutting knife 605, and the arc-shaped fixing block 505 will not break away under the action of the spring 506. Finally, turn on the cutting motor 603, the cutting motor 603 drives the rotating rod 604 to rotate, and the cutting knife 605 rotates accordingly. Finally, the hydraulic rod 602 is activated to make the cutting knife 605 move downward, and the cutting knife 605 cuts the elevator guide rail.
