Description

Technical Field

[0001] The utility model relates to the technical field of elevator components, and more specifically to a reverse rope wheel rope blocking device. Background Art

[0002] The main function of the anti-ropes is to reduce the output power and torque of the traction machine and control the tension and position of the traction rope. Anti-ropes are usually set on the movable pulleys at the top of the car and the top of the counterweight, as well as the fixed pulleys in the machine room. According to the needs, the traction wire rope can be bypassed by the anti-ropes to form different traction rope transmission ratios to achieve the control of the elevator speed and acceleration. By setting the anti-ropes, the output power and torque of the traction machine can be reduced and the efficiency of the traction system can be improved. At the same time, the anti-ropes can also control the tension and position of the traction rope to ensure the stable operation of the traction rope on the traction wheel. This is crucial for the normal operation of the elevator, especially in high-rise and high-speed elevators, where the anti-ropes can improve the smoothness and comfort of the elevator operation.

[0003] At present, the rope-blocking devices adopted for the heavy reverse rope pulley in the market include rope-blocking plates and rope-blocking rods.

[0004] Disadvantages: When the elevator stops, the 125% brake test will cause huge rebound force, and the wire rope will be out of the groove, causing huge damage;

[0005] The distance between the rope stop device and the wire rope groove and the wire rope should not be too large or too small. Moreover, as the number of uses increases, the wear of the wire rope and the displacement of the rope stop device will cause failures. Therefore, we propose an anti-rope wheel rope stop device to solve the above problems. Utility Model Content

A connecting bolt that penetrates the sleeve is installed at one end of the first connecting frame and the second connecting frame corresponding to the pressure wheel, and a first flat washer, a first spring sheet and a nut are installed in sequence at the end of the connecting bolt.

[0013] Furthermore, a first waist hole corresponding to the screw hole is provided at one end of the first connecting frame close to the mounting seat, and the first waist hole is arranged transversely;

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a first waist hole 12 corresponding to the screw hole 3 is provided at one end of the first connecting frame 4 close to the mounting seat 2, and the first waist hole 12 is arranged horizontally;
