[0025] In the description of the invention of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention of the utility model can be understood according to specific circumstances.
[0026] Example 1: See Figures 1 to 6 The utility model provides an automatic door for an elevator, comprising two vertical guide rails 1 arranged opposite to each other, the two guide rails 1 are respectively fixedly arranged on both sides of the entrance end of the elevator 15, and a slide groove is provided on the opposite side of each guide rail 1, and a plurality of guardrails 2 are slidably arranged in the slide groove;
[0027] Furthermore, a plurality of partitions are provided in the slide groove, and the partitions divide the slide groove into a plurality of sliding areas, and each guardrail 2 slides in one of the sliding areas respectively. This design can ensure that the guardrail 2 always maintains a vertical state when sliding up and down, and will not be displaced when sliding, thereby improving the smoothness of the use of the device;
[0028] A guardrail 2 located at the top is fixedly connected to the upper end of the guide rail 1, and the multiple guardrails 2 are linked by linkage units 3, and the linkage units 3 are respectively located on both sides of the guardrail 2;
[0029] A slide rail 4 is fixedly arranged on each guide rail 1 , and a slider 5 is slidably arranged on the slide rail 4 .
[0030] The two slide blocks 5 are fixedly connected via a cross bar, which is located below the lifting platform of the lift 15 .
[0031] The linkage unit 3 includes an active pulley 7 rotatably arranged at the upper end of the upper guardrail 2 , and an active pull rope 8 is fixedly arranged at the upper end of the middle guardrail 2 , and the active pull rope 8 passes around the active pulley 7 and is fixedly connected to the slider 5 .
[0032] An intermediate pulley 9 is rotatably arranged at the upper part of both ends of the middle guardrail 2, and a driven pull rope 10 is fixedly arranged at the upper end of the lower guardrail 2. The driven pull rope 10 passes over the intermediate pulley and is fixedly connected to the lower end of the upper guardrail 2.
[0033] The guardrail 2 comprises a rectangular guard frame formed by welding four round tubes end to end in sequence, and a guard net is fixedly arranged in the guard frame.
[0034] When the utility model is used, when the lifting platform moves upward, the guardrail 2 moves downward under the action of its own gravity. As the lifting platform rises, the guardrail automatically falls, driving the slider 5 to move upward. The moving speed of the slider 5 is affected by the rising speed of the elevator 15, and the entrance end of the elevator 15 is protected.
[0035] When the lifting platform descends, the lifting platform drives the slider to move downward. At this time, the guardrail 2 in the middle moves upward under the action of the active pull rope 8, and the lower guardrail 2 moves upward synchronously under the action of the driven pull rope 10. When the lifting platform descends to the lowest end, the guardrail 2 moves to the upper end of the guide rail 1. At this time, the entrance end of the elevator 15 is open, which is convenient for people and goods to enter and exit.
[0036] The device does not require additional power, and the lifting and lowering of the guardrail 2 is achieved through the operation of the lift 15. It has a simple structure and low cost, and effectively avoids the risk of personnel intrusion.
[0037] Embodiment 2: Based on Embodiment 1, a linkage 6 is rotatably arranged on the slider 5
[0038] The linkage 6 includes a pressure plate 11 rotatably disposed on the slider 5, one end of the pressure plate 11 close to the slider 5 is rotatably connected to the slider 5, and a protrusion 12 is fixedly disposed on the rotating shaft end of the pressure plate 11 close to the slider 5;
[0039] A limit platform 13 is fixedly arranged on the slide block 5 .
[0040] The limit platform 13 can limit the rotation angle of the pressure plate 11. When the guardrail 2 needs to be used, the pressure plate 11 is rotated to keep the pressure plate 11 in a horizontal state. At this time, the pressure plate 11 extends to the bottom of the elevator platform. When the elevator platform moves up and down, it can synchronously drive the slider 5 to move up and down. When the guardrail 2 is not needed, the pressure plate 11 is rotated to keep the pressure plate 11 in a vertical state. At this time, the up and down movement of the elevator platform will not affect the movement of the slider 5.
[0041] A lock buckle 14 is rotatably provided at the middle of the lower end of the lower guardrail 2. The lock buckle 14 is S-shaped. One of the bent parts of the lock buckle 14 is rotatably connected to the lower guardrail 2, and the other bent part is detachably connected to the middle guardrail 2.
[0042] Furthermore, a lock 14 is also rotatably set in the middle part of the lower end of the middle guardrail 2. One of the bent parts of the lock 14 is rotatably connected to the middle guardrail 2, and the other bent part is detachably connected to the upper guardrail 2. When the elevator is being inspected and the guardrail 2 needs to remain in a normally open state, the operator respectively engages the lock 14 on the lower guardrail 2 with the middle guardrail 2, and engages the lock 14 of the middle guardrail 2 with the upper guardrail 2, so that the three guardrails 2 are fixed. At this time, the guardrail 2 remains in a normally open state, which is convenient for the operator to inspect the elevator.
[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
