DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1 and Figure 2 As shown, the utility model discloses an elevator traction machine assembly, including a rotor 700 and a traction rope 500. A first limiting groove 710 is opened on the rotor 700, and the traction rope 500 is located in the first limiting groove 710. The first limiting groove 710 is used to limit the traction rope 500 from falling off from the rotor 700. One end of the traction rope 500 is fixed to the elevator car, and the other end of the traction rope 500 is fixed to the counterweight block. When the driving device of the rotor 700 is working, the rotor can be rotated, and then the friction between the rotor 700 and the traction rope 500 can make the traction rope 500 move therewith, thereby realizing the raising or lowering of the elevator car.
[0021] A protection rope 400 is also provided, and the protection rope 400 is arranged at one end of the rotor 700. One end of the protection rope 400 is fixedly connected to the elevator car, and the other end of the traction rope 500 is fixedly connected to the counterweight. When the traction rope 500 is in a taut state, the protection rope 400 is in a loose state, so that the protection rope 400 is not subjected to stress during normal operation of the elevator, thereby ensuring that it will not break. Once the traction rope 500 breaks, the protection rope 400 is instantly tightened, thereby being able to protect the elevator car.
[0022] Combination Figure 2 - Figure 4 As shown, in order to support the protection rope 400, a support seat 100 is also provided here. The support seat 100 is located at one end of the rotor 700. A protrusion 110 is fixedly provided at the end of the support seat 100 close to the rotor 700. The support seat 100 and the protrusion 110 both serve as supporting components.
[0023] A protection rope support mechanism 800 is also provided, and the protection rope support mechanism 800 includes a second compensation spring 840, one end of the second compensation spring 840 is fixedly connected to the boss 110, and a lifting ring 810 is installed on the other end of the second compensation spring 840. The lifting ring 810 is supported to a certain height by the second compensation spring 840, and a second limiting groove 820 is provided on the outer surface of the lifting ring 810. The protection rope 400 is located in the second limiting groove 820 to limit the protection rope 400 and prevent the protection rope 400 from falling off the lifting ring 810.
[0024] The relaxed state of the protection rope 400 mentioned above should mean that the protection rope 400 does not exert pressure on the lifting ring 810 when the elevator is in normal operation.
[0025] The lifting ring 810 is fixed to the support seat 100 through the fixing rod 880, so that the lifting ring 810 does not rotate with the rotor 700, that is, the lifting ring 810 is in a fixed state. When the rotor 700 keeps rotating and the traction rope 500 keeps moving, the protection rope 400 can be driven to move together, and the protection rope 400 and the lifting ring 810 move relative to each other. On the contrary, when the traction rope 500 breaks, the protection rope 400 is instantly tightened, which can press down the lifting ring 810, and the compensation spring 2 840 is compressed. The protection rope 400 lifts the car to protect the car. The compensation spring 2 840 can play a buffering role on the car to compensate for the instantaneous change of the protection rope 400 from a relaxed state to a tightened state, thereby improving the comfort of passengers riding the elevator.
[0026] Combination Figure 1 - Figure 5 As shown, a boss 110 is fixedly provided on one side of the support seat 100 close to the rotor 700, and the protection rope support mechanism 800 also includes a fixing plate 830, which is an arc-shaped structure located directly above the boss 110, and the arc-shaped structure is cocentric with the lifting ring 810, and the arc-shaped structure and the boss 110 are connected by bolts or welding, so as to lock the position of the fixing plate 830, and then realize the position locking of the lifting ring 810.
[0027] An assembly tube 870 is also provided. The assembly tube 870 is fixedly arranged in the middle of the lower surface of the fixing plate 830, and the assembly tube 870 is embedded in the protrusion 110. A guide rod 850 is inserted into the assembly tube 870 from the upper end. The guide rod 850 can guide the extension and retraction of the lifting ring 810 so that it can only be displaced in the vertical direction to avoid the position of the lifting ring 810 from being skewed. A compensation spring 860 is fixedly arranged between the lower part of the guide rod 850 and the bottom surface of the assembly tube 870. The upper end of the guide rod 850 is fixedly connected to the inner surface of the arc top of the lifting ring 810. The compensation spring 860 can further guide the lifting ring 810.
[0028] Preferably, a blind hole 111 for accommodating the assembly tube 870 is opened on the upper surface of the boss 110 .
[0029] like Figure 1 and Figure 2 As shown, since the protection rope 400 is initially in a loose state, in order to further prevent the protection rope 400 from falling off the lifting ring 810, a limiting guide wheel 200 is installed on the outer edge of the support seat 100 close to the rotor 700, and a groove that fits with the protection rope 400 is opened on the limiting guide wheel 200, so that the groove is used to limit the protection rope 400 from falling off from the second limiting groove 820.
[0030] Combination Figure 1 - Figure 3 As shown, a rotating shaft 740 is fixedly provided at one end of the rotor 700 close to the supporting seat 100, one end of the rotating shaft 740 is connected to the driving motor, and the other end of the rotating shaft 740 passes through the boss 110 and is fixedly connected to the rotor 700, and a rotor limiting plate 730 is installed on the rotating shaft 740, and the rotor limiting plate 730 is rotatably connected to the supporting seat 100 through a bearing.
[0031] like Figure 1 and Figure 2 A positioning frame 300 is fixedly provided on one side of the support seat 100 away from the rotor 700 , and the rotating shaft 740 is rotatably connected to the positioning frame 300 through a bearing, so that the rotation of the rotor 700 can be more stable.
[0032] The working principle and use process of the utility model are as follows: when the elevator is in normal use, the driving motor drives the rotating shaft 740 to rotate, so that the rotating shaft 740 can drive the rotor 700 to rotate. When the rotor 700 rotates, the friction between the rotor 700 and the traction rope 500 can make the traction rope 500 move therewith, thereby realizing the raising or lowering of the elevator car. At this time, the protection rope 400 is in a relaxed state, and the elevator car or the counterweight block pulls the protection rope 400 to move along the lifting ring 810. Once the traction rope 500 breaks, the protection rope 400 instantly squeezes the compensation spring 1 860 and the compensation spring 2 840, and quickly tightens to provide pulling force to the car to prevent the car from falling.
[0033] To sum up, the elevator traction machine assembly is provided with a protection rope 400. When the elevator is in normal operation, the protection rope 400 is in a relaxed state, so that it is almost not subjected to tensile stress. It can maintain a strong tensile performance. Therefore, once the traction rope 500 breaks, the protection rope 400 is instantly tightened and relies on itself to apply tension to the car to prevent the car from falling.
