Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to an elevator guide wheel assembly. Background Technology

[0002] An elevator is a fixed lifting device that serves designated floors. During operation, the elevator car is pulled by traction ropes. In the process of traction rope operation, the guide wheel needs to cooperate with the traction rope to change the direction of the traction rope, thereby realizing the vertical lifting and lowering movement of the elevator car.

[0003] In existing elevator guide wheel assemblies, when in operation, the operator usually passes the traction rope through the rope groove on the guide wheel and then guides the traction rope to change its direction. After working for a period of time, the operator needs to lubricate the traction rope to reduce the friction between the guide wheel and the traction rope and improve the service life of the guide wheel and the traction rope.

[0004] Existing elevator guide wheel assemblies have the following problems: during elevator operation, the traction rope may fall out of the rope groove of the guide wheel, affecting the operation of the elevator and posing a safety hazard. To address this, we propose an elevator guide wheel assembly. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an elevator guide wheel assembly. By using an anti-drop mechanism to limit the traction rope, the operation of the elevator is prevented from being affected by the traction rope falling out of the rope groove of the guide wheel, thus eliminating safety hazards and effectively solving the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an elevator guide wheel assembly, including a fixed base, a guide wheel installed inside the fixed base, and rope grooves evenly distributed on the outer surface of the guide wheel, and also including an anti-dropping mechanism;

[0007] Anti-fall-off mechanism: It includes a sliding column, a U-shaped frame, a limiting plate, a screw, a turntable, a rotating rod, and a limiting wheel. The upper surface of the fixed base is provided with a support frame at the front end. The front side of the support frame has symmetrically distributed sliding openings. The sliding columns are slidably connected inside the sliding openings. The rear ends of the two sliding columns are fixedly connected to the front side of a U-shaped frame. The front end of the sliding column is provided with a limiting plate. The front side of the U-shaped frame is rotatably connected with a screw. The outer surface of the screw is threadedly connected to the threaded hole on the front side of the support frame. The front end of the screw is provided with a turntable. The U-shaped frame has an adjustable rotating rod inside. The outer surface of the rotating rod is fixedly fitted with a limiting wheel corresponding to the rope groove. The anti-fall-off mechanism limits the traction rope, preventing the traction rope from falling out of the rope groove of the guide wheel and affecting the operation of the elevator, thus eliminating safety hazards.

[0008] Furthermore, it also includes a microcontroller, which is located outside the mounting base. The input terminal of the microcontroller is electrically connected to an external power supply to facilitate the normal operation of the control components.

[0009] Furthermore, the anti-fall-off mechanism also includes a chute, a limiting post, and a sliding seat. The left and right walls of the U-shaped frame are provided with chutes, and the inside of each chute is provided with a limiting post. The outer surface of each limiting post is slidably connected to a sliding seat, and the sliding seats are slidably connected inside the chute. The rotating rod is rotatably connected between the two sliding seats to prevent the anti-fall-off mechanism from moving too far and damaging the guide wheel and traction rope.

[0010] Furthermore, the anti-drop mechanism also includes springs, and springs are movably sleeved on the outer surface of the limiting column. The springs are located between the front side of the adjacent sliding seat and the front side wall of the slide groove, which facilitates the limiting of the traction rope.

[0011] Furthermore, the upper surface of the fixed base is provided with support seats on both the left and right sides, and a horizontal shaft is provided between the two support seats. A guide wheel is rotatably connected to the middle of the outer surface of the horizontal shaft through a bearing to support the guide wheel.

[0012] Furthermore, the upper surface of the fixed base is provided with an oil tank, and the lower surface of the oil tank is provided with oil drip nozzles that correspond one-to-one with the rope grooves, so as to facilitate the storage of lubricating oil.

[0013] Furthermore, a slot is provided inside the bottom wall of the oil tank, and a baffle is slidably connected inside the slot. An electric push rod is provided in the mounting hole on the rear side of the oil tank. The telescopic end of the electric push rod is fixedly connected to the rear side of the baffle, and the input end of the electric push rod is electrically connected to the output end of the microcontroller to facilitate oil dripping.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This elevator guide wheel assembly has the following advantages:

[0015] The rotating turntable drives the screw to rotate. Under the constraint of the sliding column, the rotation of the screw causes the U-shaped frame to move backward. The spring drives the limit wheel to move backward through the sliding seat and the rotating rod, so that the outer surface of the limit wheel is always in contact with the outer surface of the traction rope, thus limiting the traction rope and preventing the traction rope from falling out of the guide wheel's groove, which would affect the operation of the elevator and eliminate safety hazards.

The input terminal of the microcontroller 7 is electrically connected to an external power source. Support seats are provided on both the left and right sides of the upper surface of the fixed base 1, and a horizontal shaft 6 is provided between the two support seats. The guide wheel 4 is rotatably connected to the middle of the outer surface of the horizontal shaft 6 via a bearing. An oil tank 8 is provided on the upper surface of the fixed base 1, and oil drip ports 9 corresponding to the rope grooves 5 are opened on the lower surface of the oil tank 8. A groove 1 is opened inside the bottom wall of the oil tank 8. 0. A baffle 11 is slidably connected inside the groove 10. An electric push rod 12 is installed in the mounting hole on the rear side of the oil tank 8. The telescopic end of the electric push rod 12 is fixedly connected to the rear side of the baffle 11. The input end of the electric push rod 12 is electrically connected to the output end of the microcontroller 7. The operator passes the traction rope through the rope groove 5 and around the guide wheel 4. After the guide wheel 4 has been working for a period of time, the microcontroller 7 is operated to open the electric push rod 12. The telescopic end of the electric push rod 12 drives the baffle 11 to slide in the groove 10 until the oil drip port 9 is opened. The lubricating oil in the oil tank 8 drips onto the traction rope through the oil drip port 9, reducing the friction between the guide wheel 4 and the traction rope and improving the service life of the guide wheel 4 and the traction rope.

[0024] Anti-fall-off mechanism 3: It includes a sliding column 301, a U-shaped frame 302, a limiting piece 303, a screw 304, a turntable 305, a rotating rod 306, and a limiting wheel 307. A support frame 2 is provided at the front end of the upper surface of the fixed base 1. Symmetrically distributed sliding openings are provided on the front side of the support frame 2. Sliding columns 301 are slidably connected inside each sliding opening. The rear ends of two sliding columns 301 are fixedly connected to the front side of a U-shaped frame 302. A limiting piece 303 is provided at the front end of each sliding column 301. A screw 304 is rotatably connected to the front side of the U-shaped frame 302. The screw 304 has a threaded connection between its outer surface and the threaded hole on the front side of the support frame 2. A turntable 305 is located at the front end of the screw 304. An adjustable rotating rod 306 is located inside the U-shaped frame 302. A limiting wheel 307, corresponding to the rope groove 5, is fixedly fitted onto the outer surface of the rotating rod 306. The anti-drop mechanism 3 also includes a sliding groove 308, a limiting post 309, and a sliding seat 310. Sliding grooves 308 are provided on both the left and right walls of the U-shaped frame 302, and limiting posts 309 are located inside each sliding groove 308. Each limiting post 309 has a sliding seat 310 slidably connected to its outer surface. The sliding seats 310 are slidably connected to the inside of the slide groove 308. A rotating rod 306 is rotatably connected between two sliding seats 310. The anti-drop mechanism 3 also includes a spring 311. Each limiting post 309 has a spring 311 movably fitted onto its outer surface. The springs 311 are located between the front side of adjacent sliding seats 310 and the front side wall of the slide groove 308. Then, the turntable 305 is rotated, causing the screw 304 to rotate. The sliding post 301... Under the constraint, the rotation of the screw 304 drives the U-shaped frame 302 to move backward, causing the limit wheel 307 to move backward until the outer surface of the limit wheel 307 contacts the outer surface of the traction rope. Under the action of the spring 311's rebound force, the spring 311 drives the limit wheel 307 to move backward along the slide groove 308 through the sliding seat 310 and the rotating rod 306, so that during the operation of the elevator, the outer surface of the limit wheel 307 is always in contact with the outer surface of the traction rope, limiting the traction rope and preventing it from falling out of the rope groove 5.

[0025] The working principle of the elevator guide wheel assembly provided by this utility model is as follows: The operator passes the traction rope through the rope groove 5 and around the guide wheel 4, and then rotates the turntable 305. The rotation of the turntable 305 drives the screw 304 to rotate. Under the restriction of the sliding column 301, the rotation of the screw 304 drives the U-shaped frame 302 to move backward, causing the limiting wheel 307 to move backward until the outer surface of the limiting wheel 307 contacts the outer surface of the traction rope. Under the action of the spring 311's rebound force, the spring 311 drives the limiting wheel 307 through the sliding seat 310 and the rotating rod 306. Moving backward along the slide 308, the outer surface of the limit wheel 307 remains in contact with the outer surface of the traction rope during elevator operation, limiting the traction rope and preventing it from falling out of the rope groove 5. After the guide wheel 4 has been working for a period of time, the microcontroller 7 opens the electric push rod 12. The telescopic end of the electric push rod 12 drives the baffle 11 to slide in the groove 10 until the oil drip port 9 opens. The lubricating oil in the oil tank 8 drips onto the traction rope through the oil drip port 9, reducing the friction between the guide wheel 4 and the traction rope and improving the service life of the guide wheel 4 and the traction rope.

[0026] It is worth noting that the microcontroller 7 disclosed in the above embodiments can be a PIC10F200, and the microcontroller 7 controls the operation of the electric push rod 12 using methods commonly used in the prior art.
