The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] The following describes an embodiment of the present invention based on its overall structure.

[0040] Example 1:

[0041] A guide wheel structure of an elevator balance chain, such as Figure 1-Figure 7As shown, it includes a support frame 1 and a movable plate 5, a positioning plate 2 and an adjustment component 9 are respectively provided inside the support frame 1, a guide wheel 8 is provided on the support frame 1, and a guide groove 18 is provided on the outer wall of the guide wheel 8, so that the staff can wind the balance chain around the inner wall of the guide groove 18 opened by the guide wheel 8, and the adjustment component 9 includes a motor 901 installed inside the support frame 1, the output end of the motor 901 is connected to the drive shaft 902, and the outer wall of the drive shaft 902 is installed with a winding roller 903, and the outer wall of the winding roller 903 is wound with a wire rope 904, one end of the wire rope 904 passes through the positioning plate 2 and is connected to the bottom of the movable plate 5, and a disassembly component 17 is provided on the movable plate 5.

[0042] Specifically, the disassembly component 17 includes a positioning groove 1702 opened at the top of the movable plate 5 and a groove 1705 opened inside the movable plate 5. A positioning block 1701 is inserted into the positioning groove 1702, and a card slot 1704 is opened on one side of the positioning block 1701. A return spring 1706 is installed inside the groove 1705, and one end of the return spring 1706 is connected to a card plate 1703 extending to the inside of the card slot 1704. A pull rod 1707 is installed on one side of the card plate 1703 and passes through the outside of the movable plate 5. When the card plate 1703 is moved out of the card slot 1704, it no longer locks the positioning block 1701. At this time, the cleaning brush 7 can be taken out upwards to replace the cleaning brush 7.

[0043] Specifically, one end of the pull rod 1707 is connected to a pull plate 1708, and the card plate 1703 is adapted to the card slot 1704. When the cleaning brush 7 needs to be replaced, the staff can pull the pull plate 1708, and the movement of the pull plate 1708 drives the pull rod 1707 to move, and then drives the card plate 1703 to move. The positioning block 1701 is adapted to the positioning slot 1702. The cleaning brush 7 and the mounting plate 6 are both detachably connected to the movable plate 5 through the positioning block 1701. When the positioning block 1701 is inserted into the positioning slot 1702, the mounting plate 6 and the cleaning brush 7 can be positioned, which is convenient for the installation of the cleaning brush 7.

[0044] See Figure 2-Figure 6 , a spring 4 and a telescopic rod 3 are respectively installed on the top of the positioning plate 2, and the top of the spring 4 and the telescopic rod 3 are connected to a movable plate 5. When the movable plate 5 moves down, it will squeeze the spring 4 and the telescopic rod 3, and the spring 4 is compressed, and the telescopic rod 3 is contracted at the same time. A mounting plate 6 is provided on the top of the positioning block 1701, and a cleaning brush 7 is provided on the top of the mounting plate 6, and the top of the cleaning brush 7 is in contact with the guide wheel 8. The cleaning brush 7 can clean the outer wall of the guide wheel 8, reduce the wear of the guide wheel caused by dust and oil stains, and reduce the wear of the balance chain. The outer surface and back of the movable plate 5 are both in contact with the inner wall of the support frame 1, and the movable plate 5 is slidably connected to the support frame 1 so that the movable plate 5 can move in the support frame 1 and improve the stability of the movable plate 5 when moving.

[0045] Example 2:

[0046] On the basis of the above-mentioned embodiment 1, in order to facilitate the stable positioning of the balance chain, the following structure is provided.

[0047] See Figures 1-4 The cam 16 is connected to the fixed frame 10 on both sides of the support frame 1, and the inner wall of the fixed frame 10 is provided with two slide grooves 15, and the inner part of the slide groove 15 is provided with a slide seat 16, and a movable frame 11 is installed between every two slide seats 16. When the movable frame 11 moves, it will drive the slide seat 16 to slide inside the slide groove 15, thereby improving the stability of the movable frame 11 when moving. A positioning shaft 12 is provided on one side of the movable frame 11, and the movable frame 11 is slidably connected to the slide groove 15 through the slide seat 16, and a threaded rod 13 is connected to the other side of the movable frame 11 through a bearing. When the threaded rod 13 rotates, it will move and drive the movable frame 11 to move so as to adjust the position of the movable frame 11. One end of the threaded rod 13 extends to the outside of the fixed frame 10 and is connected to a handwheel 14, and the outer wall of the handwheel 14 is sleeved with an anti-slip sleeve. The threaded rod 13 is threadedly connected to the fixed frame 10, which is convenient for the staff to rotate the threaded rod 13 through the handwheel 14. The setting of the anti-slip sleeve facilitates the rotation of the handwheel 14.

[0048] The working principle of the utility model is as follows: first, when the guide wheel structure of the elevator balance chain needs to be used, the staff will wrap the balance chain around the inner wall of the guide groove 18 opened by the guide wheel 8, stably position the support frame 1 on one side of the car and turn on the power. The hand wheel 14 is turned, so that the hand wheel 14 drives the threaded rod 13 to rotate, and the threaded rod 13 moves and drives the movable frame 11 to move. The movable frame 11 drives the positioning shaft 12 to move so that the positioning shaft 12 can contact one side of the balance chain, so that the balance chain is stably positioned through the guide groove 18 and the positioning shaft 12, reducing the hidden danger of the balance chain falling off due to inertia, tension, etc.

[0049] When there is no need to clean the outer wall of the guide wheel 8, the motor 901 can be started. The motor 901 can drive the driving shaft 902 to rotate, and drive the winding roller 903 to rotate, so that the winding roller 903 reels the wire rope 904, and the wire rope 904 pulls the movable plate 5 downward, and then drives the cleaning brush 7 to move downward, so that the cleaning brush 7 does not contact the guide wheel 8, thereby preventing the guide wheel 8 from always contacting the cleaning brush 7 and accelerating the wear of the cleaning brush 7;

[0050] If the outer wall of the guide wheel 8 needs to be cleaned, the motor 901 can be started, so that the motor 901 drives the driving shaft 902 to reverse, and drives the winding roller 903 to reverse. At this time, the winding roller 903 releases the wire rope 904, and the spring 4 stretches to push the movable plate 5 to move up and reset, and drives the cleaning brush 7 to move up and reset, so that the cleaning brush 7 fits the outer wall of the guide wheel 8, which is convenient for cleaning the outer wall of the guide wheel 8;

[0051] When the cleaning brush 7 needs to be replaced, the cleaning brush 7 is first adjusted by the component 9 so that it is not in contact with the guide wheel 8. Then the staff can pull the pull plate 1708. The movement of the pull plate 1708 drives the pull rod 1707 to move, and then drives the card plate 1703 to move. When the card plate 1703 is moved out of the card slot 1704, it no longer locks the positioning block 1701. At this time, the cleaning brush 7 can be taken out upwards to replace the cleaning brush 7.

[0052] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
