Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Referring to Figures 1-5 , a hanging basket elevator capable of adjusting the tightness between the guide wheel and the steel wire rope, including a hanging basket 1, a distribution box 2 is installed on the side wall of the hanging basket 1, hoists 3 are installed on the opposite sides of the hanging basket 1, safety locks 4 are installed on the opposite sides of the hanging basket 1. The distribution box 2, the hoist 3 and the safety lock 4 are all prior arts and will not be elaborated here. Two rotating rods 5 are arranged below each safety lock 4. Two fixed rods 6 are fixedly connected to the two side walls of the hanging basket 1. Two connecting rods 7 are fixedly connected to the two side walls of each fixed rod 6. The other end of each connecting rod 7 is rotatably connected to the corresponding rotating rod 5. The lower end of each fixed rod 6 is elastically connected to the upper end of the corresponding rotating rod 5 through a first spring 8. Each first spring 8 is a tension spring. A guide wheel 9 is rotatably connected between every two cooperating rotating rods 5. When the pressure of the steel wire rope on the guide wheel 9 is less than the pulling force of the first spring 8 on the rotating rod 5, the rotating rod 5 will rotate upward. In this way, whether the steel wire rope is loose can be observed through the rotation of the rotating rod 5, and then the tightness between the steel wire rope and the guide wheel 9 can be adjusted;

[0025] Among them, a first steel wire rope 10 is arranged in each of the two elevators 3. The other ends of the two first steel wire ropes 10 extend to the outside and are fixedly connected with sleeves 11. Threaded rods 12 are threadedly connected in the two sleeves 11. Second steel wire ropes 13 are arranged above the two threaded rods 12. The lower ends of the two second steel wire ropes 13 are rotatably connected with rotating cylinders 14. The lower ends of the two rotating cylinders 14 are fixedly connected with the upper ends of the corresponding threaded rods 12. The upper ends of the two second steel wire ropes 13 are fixedly connected with mounting blocks 15. Third steel wire ropes 16 are arranged above the two mounting blocks 15. The two third steel wire ropes 16 sequentially pass through the corresponding guide wheels 9 and safety locks 4. By rotating the rotating cylinder 14, the threaded rod 12 is rotated into the sleeve 11, and by rotating the rotating cylinder 14 in the reverse direction, the threaded rod 12 can be screwed out of the sleeve 11. By moving the threaded rod 12 up and down, the length of the third steel wire rope 16 is adjusted, and further the tightness between the third steel wire rope 16 and the guide wheel 9 is adjusted. When the rotating rod 5 returns to its original position, the tightness adjustment is completed. The lower ends of the two third steel wire ropes 16 are fixedly connected with fixing blocks 17. The lower ends of the two fixing blocks 17 are fixedly connected with inserting blocks 18;

[0026] Among them, slots 19 matching the corresponding inserting blocks 18 are opened at the upper ends of the two mounting blocks 15. The inserting blocks 18 are inserted into the slots 19 to complete the preliminary limit fixation of the mounting blocks 15 and the fixing blocks 17. Limiting mechanisms for limiting the corresponding inserting blocks 18 are arranged on the inner walls of the two slots 19. The two limiting mechanisms each include a slider 21. The two sliders 21 are slidably connected with the inner walls of the corresponding slots 20. One ends of the two sliders 21 are fixedly connected with limiting blocks 22. Limiting grooves 23 matching the corresponding limiting blocks 22 are opened on the side walls of the two inserting blocks 18. By snapping the limiting blocks 22 into the limiting grooves 23, the final limit fixation of the mounting blocks 15 and the fixing blocks 17 is realized. The other ends of the two sliders 21 are elastically connected with the inner walls of the corresponding slots 20 through second springs 24. The other ends of the two sliders 21 are fixedly connected with pull rods 25. The other ends of the two pull rods 25 extend to the outside and are fixedly connected with pulling plates. Protective layers are arranged on the outer side walls of the two pulling plates. The two protective layers are both made of rubber material. Through the cooperation of the sliders 21, the limiting blocks 22 and the second springs 24, the removal and installation of the third steel wire rope 16 are convenient and simple, so that it is convenient to replace the damaged third steel wire rope 16.

[0027] In the present utility model, during use, when the third steel wire rope 16 becomes loose, the pressure of the third steel wire rope 16 on the guide wheel 9 will be less than the pulling force of the first springs 8 on the rotating rod 5. In this way, under the pulling forces of the multiple first springs 8, the rotating rod 5 will rotate upward, so that the tightness between the third steel wire rope 16 and the guide wheel 9 can be observed through the rotation of the rotating rod 5, making it convenient to adjust the tightness of the two.

[0028] Then, the rotating cylinder 14 can be rotated. The rotating cylinder 14 will drive the threaded rod 12 to rotate and move the threaded rod 12 into the sleeve 11. Conversely, the threaded rod 12 can be screwed out. By adjusting the moving distance of the threaded rod 12, when the pressure of the third steel wire rope 16 on the guide wheel 9 is greater than the pulling force of the first spring 8 on the rotating rod 5, the rotating rod 5 will return to its original position, that is, the tightness between the third steel wire rope 16 and the guide wheel 9 is adjusted.

[0029] When the third steel wire rope 16 is damaged, the pull rod 25 can be pulled to move the slider 21, and then the limiting block 22 is separated from the limiting groove 23, so that the limitation on the insertion block 18 is released, and the third steel wire rope 16 can be taken out. Without releasing the hand, the insertion block 18 of the new third steel wire rope 16 is inserted into the insertion slot 19, and then the pull rod 25 is released. Under the elastic action of the second spring 24, the slider 21 will return to its original position, and then the limiting block 22 is engaged in the limiting groove 23, thus completing the installation of the third steel wire rope 16. In this way, the removal and installation of the third steel wire rope 16 are convenient and simple, which is convenient for replacing the damaged third steel wire rope 16.

[0030] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
