The existing rail carriage door system has a cutting device with a misoperation function, which includes a base, a guide rail cutting assembly, and a guide rail fixing assembly. Before cutting, a measuring ruler is required to measure. The values read by the measuring ruler at different positions will deviate, resulting in deviations in the guide rails of the rail carriage door after the cut.

[0021] As attached Figure 2 As shown, in the above embodiment, specifically, a cutting tool 61 is provided on the inner side of the sliding column 6, and sliding connecting tubes 62 are welded to the four outer corners of the cutting tool 61 to ensure that the cutting tool 61 can be lifted and lowered vertically.

[0022] As attached Figure 2 As shown, in the above embodiment, specifically, a reset spring 63 is sleeved on the lower outer side of the sliding column 6, and the reset spring 63 is located at the lower part of the sliding connecting tube 62, which can push the cutting tool 61 to automatically reset after the cutting is completed.

[0023] In the above embodiment, specifically, the lower shaft of the pulley pressure rod 10 is connected to a fixed roller, and the fixed roller at the lower part of the pulley pressure rod 10 contacts the upper part of the cutting tool 61, reducing the friction between the pulley pressure rod 10 and the cutting tool 61 when pressing.

[0024] In the above embodiment, specifically, an anti-error lock hole 611 is opened on the lower inner part of the cutting tool 61, and the rear end of the output rod of the micro electric push rod 21 is inserted into the inner side of the anti-error lock hole 611, and cooperates with the infrared sensor 51 to prevent staff from making operating errors, resulting in a shorter cutting distance of the carriage door guide rail, thereby causing waste of materials.

[0025] In the above embodiment, specifically, the front end of the cutting tool 61 is tightly fitted with the rear surface of the metal vertical plate 2, and the cutting tool 61 is located at the upper part of the vehicle door guide rail fixing groove 3, and the vehicle door guide rail is cut by raising and lowering the cutting tool 61.

[0026] In the above embodiment, specifically, the upper surface of the rotating metal strip 41 is engraved with scale lines, and the rotating metal strip 41 is arranged on the left side of the metal vertical plate 2 .

[0027] In the above embodiment, specifically, the lower portion of the locking bolt 43 passes through the left side of the rotating metal bar 41 and is threadedly connected to the anti-slip base 1, thereby fixing the rotating metal bar 41 and locking the rotating metal bar 41 at the same time.

[0028] In the above embodiment, specifically, the infrared sensor 51 is located on the upper portion of the rotating metal bar 41 , and the side connecting plates 54 are respectively located at the front and rear ends of the rotating metal bar 41 .

[0030] How it works

[0031] The working principle of the present invention is as follows: according to the length of the carriage door in the rail transit system, the length of the carriage door guide rail is determined, and then the long guide rail is taken out for standby, the rotating metal bar 41 is rotated forward so that the rotating metal bar 41 and the anti-slip base 1 are perpendicular to each other, and then the locking bolt 43 is tightened. Then, according to the length of the cut, the position of the infrared sensor 51 is adjusted, and the infrared sensor 51 is slid on the outside of the rotating metal bar 41 through the mutual cooperation between the side connecting plate 54 and the rectangular slider 55 and the limit card slot 42, so that the center of the infrared sensor 51 is aligned with the position to be cut, and the carriage door guide rail is inserted from the back to the front so that the end of the carriage door guide rail is located between the two infrared probes on the left side of the infrared sensor 51. At this time, one of the infrared probes on the left side of the infrared sensor 51 is in a blocked state, and the other is in an unblocked state. Otherwise, the prompt buzzer 52 will sound a prompt to remind the staff, and the micro electric push rod 21 will not move. After the end of the guide rail is placed to meet the cutting conditions, the infrared sensor 51 controls the output rod of the micro electric push rod 21 to retract, and the output rod of the micro electric push rod 21 is separated from the inner side of the anti-error lock hole 611. The staff holds the end of the metal pressure rod 9 and presses it downward, and pushes the cutting tool 61 downward through the pulley pressure rod 10 until the car door guide rail is cut off. After releasing, the reset spring 63 pushes the sliding connecting tube 62 to move upward, so that the cutting tool 61 is automatically reset.

[0032] Utilizing the technical solution described in the present invention, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present invention to achieve the above technical effects, all fall within the scope of protection of the present invention.
