DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a vertical elevator balance chain guide device, comprising:

[0022] A bracket 1, a transmission groove 2 is penetrated in the middle of the bracket 1, and sliding grooves 3 are penetrated at both ends of the bracket 1. The sliding grooves 3 are located at the ends of the bracket 1, and the sliding grooves 3 penetrate the bracket 1 front and back;

[0023] Fine-tuning component; the fine-tuning component includes two adjustment plates 8 sliding in two sliding grooves 3 respectively, and the bottom and inner top of the sliding groove 3 are provided with a guide groove 14, and a slide plate 9 is slidably connected in the guide groove 14, and the slide plate 9 is fixedly connected to the adjustment plate 8. Through the cooperation between the guide groove 14 and the slide plate 9, the stable movement of the adjustment plate 8 can be guaranteed.

[0024] A threaded groove is provided on the adjusting plate 8, and a screw 13 is threadedly connected in the threaded groove. A driving mechanism for driving the two screws 13 to rotate synchronously is installed on the bracket 1, and the driving mechanism includes two shafts 4 arranged in the transmission groove 2, and the shafts 4 penetrate the bracket 1 and are rotatably connected thereto. The two shafts 4 are fixedly connected to the two screws 13 respectively, and a first bevel gear 5 is fixed on the two shafts 4. A handle 7 that is rotatably arranged penetrates the bracket 1, and a second bevel gear 6 is fixed on the handle 7, and the second bevel gear 6 is meshed with the two first bevel gears 5.

[0025] A mounting frame 10 is installed at the other end of the adjustment plate 8. A plurality of guide wheel groups are installed in the mounting frame 10. A mounting plate 11 is installed on the mounting frame 10. Each guide wheel group includes two guide wheels 12. A fixed shaft 15 is provided on the guide wheel 12. The fixed shaft 15 is rotatably connected to the inner wall of the mounting frame 10. The balance chain can be guided by the guide wheel 12.

[0026] When in use, the staff rotates the handle 7 to drive the second bevel gear 6 to rotate, and the rotation of the second bevel gear 6 drives the two first bevel gears 5 to rotate, so that the two shafts 4 are rotated and the rotation directions of the shafts 4 are opposite. Since the thread directions of the two screws 13 are the same, the two adjustment plates 8 can be moved relative to or away from each other. The movement of the adjustment plate 8 drives the installation frame 10 and the installation plate 11 to move. The installation plate 11 is provided with bolt holes so that the installation plate 11 is abutted against the installation position. Both the two installation plates 11 are abutted against the installation surface.
