Fig. 2 is a schematic structural view of an elevator guide rail retractor brake of the present utility model.
As shown in the figure: 1. a wall body; 2. a traction motor; 3. a rotating shaft; 31. a fixed box; 4. a winding wheel; 5. a brake wheel; 6. a braking device; 9. a steel rope; 10. a car; 11. a motor; 12. a fixed block; 13. a screw; 14. a groove; 15. a first limit post; 16. the second limit column; 17. and a brake elbow.
Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 to 2, an elevator guide rail tractor comprises a wall body 1, wherein a traction motor 2 is installed on the right side above the wall body 1, a fixed box 3 is installed on the right side of the traction motor 2, a rotating shaft 3 is installed at the output shaft end of the traction motor 2, the right end of the rotating shaft 3 penetrates through the left and right side box walls of the fixed box 3 and stretches out of the right side of the fixed box 31, two winding wheels 4 and braking wheels 5 are installed from left to right in the rotating shaft 3, the two winding wheels 4 and the braking wheels 5 are driven to rotate by starting the traction motor 2, a braking device 6 is installed on the right side of the fixed box 31, steel ropes 9 are respectively installed on the two winding wheels 4, and a car 10 is installed at the lower ends of the steel ropes 9.
The braking device 6 comprises a motor 11 and a fixed block 12, the motor 11 and the fixed block 12 are fixedly arranged on the upper surface of the wall body 1, a screw 13 is arranged at the output shaft end of the motor 11, a groove 14 is formed in the fixed block 12, two ends of the screw 13 are rotatably arranged in the groove 14, the screw 13 comprises a first thread section and a second thread section, the first thread section and the second thread section are in reverse thread design, a first limit column 15 and a second limit column 16 are symmetrically arranged on the first thread section and the second thread section, a braking elbow 17 is welded on the first limit column 15 and the second limit column 16, the fixed block 12 is positioned below the braking wheel 5, and the first limit column 15 and the second limit column 16 are positioned on two sides of the braking wheel 5.
Specifically, when the car 10 descends fast, the rotational speed of the winding wheel 4 becomes fast, the speed sensor on the winding wheel 4 is used for transmitting the rotational speed to the control device, the control device can start the motor 11, the motor 11 drives the screw rod 13 to rotate, the first thread section and the second thread section of the screw rod 13 are in reverse thread design, so that the screw rod 13 drives the first limit column 15 and the second limit column 16 to move relatively while rotating, the brake elbow 17 clamps the brake wheel 5, thereby the rotating shaft 3 stops rotating, and the two winding wheels 4 stop rotating, so that the elevator is in a static state.
