AI Technical Summary
The existing elevator wire rope guide wheels are prone to shake during long-term use, which affects the normal and stable walking of the wire ropes, and the friction produces broken iron chips, resulting in wear of the guide wheels.
An elevator wire rope guide pulley with stable sliding is designed. By arranging a rotating body, balls and rolling grooves in the main body of the guide pulley, the main body of the guide pulley is supported by the side of the fixed ring when rotating to ensure stable sliding of the wire rope. In addition, there is an iron magnet inside the main body of the guide wheel to absorb scrap iron filings and reduce friction and wear.
It achieves stable sliding of the elevator wire rope guide wheel, reduces shaking, and extends the service life. The design of the magnet avoids friction and wear, ensuring long-term stable operation of the guide wheel.

All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Embodiment 1
[0027] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Fig. 9 The utility model provides a technical solution: a stable sliding elevator wire rope guide wheel, including a guide wheel body 4 and a mounting shaft 2, the middle part of the guide wheel body 4 is equipped with the mounting shaft 2 through a bearing seat, a rotating body 1 is arranged on the outer side of the guide wheel body 4 close to the mounting shaft 2, and a fixing ring 3 is installed at the end of the mounting shaft 2 through bolts, and oil boxes 5 are arranged on the two side surfaces of the guide wheel body 4, and the oil boxes 5 are connected to the guide wheel body 4 through bolts.
[0028] The side of the guide wheel body 4 is provided with a built-in groove 7, and an oil outlet 6 is provided at the inner edge of the built-in groove 7; the edge of the fixed ring 3 is provided with a rotating groove 10; a rolling groove 8 is provided inside the rotating groove 10, and a ball 9 is embedded and installed inside the rolling groove 8, and the outer wall of the ball 9 is in contact with the rotating body 1; a through groove 19 is provided above the oil box 5, and a sealing seat 20 is provided inside the through groove 19, and a receiving cavity 21 is provided on both sides of the sealing seat 20, and both sides of the receiving cavity 21 penetrate the limited position Block 22; guide rods 23 are passed through both ends of the limit block 22, and a spring 24 is installed on the outer side of the guide rod 23, and the two ends of the spring 24 are respectively connected to the limit block 22 and the inner wall of the storage chamber 21, the cross-sectional shape of the rolling groove 8 is "C"-shaped, the oil outlets 6 are evenly spaced, the sealing seat 20 is made of rubber, the limit block 22 forms a telescopic structure with the spring 24 and the storage chamber 21, and the rotating body 1 and the rotating groove 10 are rollingly connected through the rolling groove 8 and the ball 9.
[0029] In the specific implementation, the lubricating oil is first injected into the oil box 5 from the inside of the through groove 19, and then the sealing seat 20 is docked in the inside of the through groove 19 and the sealing seat 20 is pressed downward. During the pressing process of the sealing seat 20, the inner wall of the through groove 19 will squeeze the limit block 22. The limit block 22 squeezed by the external force moves along the guide rod 23 to the inside of the storage cavity 21, and squeezes the spring 24 sleeved on the outside of the guide rod 23 until the sealing seat 20 is pressed to the limit position, so that the limit block 22 is elastically pressed by the spring 24. The force automatically resets outward to dock with the inner wall of the through groove 19, and the lubricating oil in the oil box 5 flows out through the built-in groove 7 and the oil outlet 6 in turn to lubricate the inside of the guide wheel body 4 and the wire rope. The guide wheel body 4 rolls and drives the rotating body 1 to rotate inside the rotating groove 10, and the rotation of the rotating body 1 drives the ball 9 to roll on the inner surface of the rolling groove 8. It is easy to control the side support of the guide wheel body 4 through the rotating body 1 and the fixed ring 3 when the guide wheel body 4 rotates, so that the elevator wire rope guide wheel is convenient for the wire rope to slide stably and is not easy to shake.
[0030] Embodiment 2
[0031] See also Figure 1 , Figure 6 , Figure 7 and Figure 8On the basis of the first embodiment, a mounting groove 17 and a bayonet 11 are provided in the middle of the inner part of the guide wheel body 4, a hollow plate 12 is installed inside the bayonet 11, and a screw 14 is connected to the end of the hollow plate 12; a rubber pressing pad 13 is installed on the hollow plate 12 through the screw 14, a magnet 15 is placed inside the mounting groove 17, and a slot body 16 is provided on the surface of the magnet 15; a clamping rod 18 is provided on the edge of the lower surface of the hollow plate 12, and the end of the clamping rod 18 away from the hollow plate 12 is inserted into the slot body 16, and the magnet 15 and the slot body 16 are both arranged in an annular shape.
[0032] During the specific implementation, the magnet 15 is first installed inside the installation groove 17, and the hollow plate 12 is installed inside the bayonet 11. When installing, the hollow plate 12 is docked and inserted into the slot body 16 through the connected clamping rod 18. The magnet 15 is squeezed and fixed by the hollow plate 12 during the closed installation, and the hollow plate 12 and the inside of the bayonet 11 are fastened and locked by rotating the screw 14. At the same time, the rubber compression pad 13 is engaged with the surface of the first screw 14 for closed protection. When the wire rope and the inner surface of the guide wheel body 4 move and generate broken iron chips, the broken iron chips are directly sucked into the installation groove 17 by the magnet 15 through the hollow plate 12, and the broken iron chips can be processed centrally, so that the elevator wire rope guide wheel and the wire rope are not easily damaged by friction when they move, and can be used stably.
[0033] During actual use, when the steel wire rope moves against the inner surface of the guide wheel body 4 and produces iron chips, the iron chips fall directly into the hollow plate 12 and are sucked into the installation groove 17 by the magnet 15 for collection, so that the steel wire rope is not easily damaged by friction when moving against the inner surface of the guide wheel body 4. Finally, when the steel wire rope moves on the inner surface of the guide wheel body 4 and drives the guide wheel body 4 to roll continuously, the guide wheel body 4 drives the rotating body 1 to rotate inside the rotating groove 10, and the rotating body 1 drives the ball 9 to roll on the inner surface of the rolling groove 8, which makes it easy to control the side support of the guide wheel body 4 through the rotating body 1 and the fixed ring 3 during rotation, so that the guide wheel body 4 is not easily shaken when the steel wire rope deviates, and it is easy to operate stably, thereby improving the stability of the use of the guide wheel body 4.
[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
