[0002] The main function of the rewinding wheel in the elevator system is to achieve rewinding in coordination with the traction wheel, thereby reducing the output power and torque of the traction machine. The rewinding structure is a common structure of high-speed elevators. As an indispensable and important component of the rewinding structure, the stability and reliability of the rewinding wheel play a great role in the entire elevator system, among which the installation of the rewinding wheel and the stability after installation are crucial. At present, the rewinding wheel is generally fixed by directly installing it on the channel steel and then installing the channel steel on the frame body by bolts. This requires opening holes in the channel steel and then installing the axle and the rewinding wheel, which makes the overall rewinding wheel installation inconvenient; moreover, the subsequent replacement of the rewinding wheel is also inconvenient. Therefore, the existing technology has the problems of inconvenient installation and inconvenient replacement of the rewinding wheel. Utility Model Content

DETAILED DESCRIPTION

[0016] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0017] Embodiment. A rewinding wheel fixing structure is composed as follows Figure 1-4 As shown, it includes a frame body 2 located above the shelf beam 1, a main machine 3 is fixed above the frame body 2, and channel steels 4 located on the inner side of the shelf beam 1 are provided at both ends of the bottom of the frame body 2, and the channel steels 4 are connected to the shelf beam 1 through fixing bolts 5; a wheel axle fixing part 6 is provided under each channel steel 4, a wheel axle 7 is provided between the two wheel axle fixing parts 6, and a winding wheel 8 is provided on the wheel axle 7; the wheel axle fixing part 6 includes an L-shaped fixing plate 9, and a wheel axle mounting hole 10 is provided on the side wall surface of the L-shaped fixing plate 9.

[0018] A reinforcing plate fixed on the inner wall surface of the L-shaped fixing plate is arranged on the inner side of the wheel axle mounting hole.

[0019] A U-shaped bent plate 11 is provided on the outer side of the upper end of the L-shaped fixing plate 9, and a slide groove 12 is formed between the U-shaped bent plate 11 and the L-shaped fixing plate 9; the upper end surfaces of the U-shaped bent plate 11 and the L-shaped fixing plate 9 are both provided with corresponding fourth through holes, and the lower end surface of the channel steel 4 is provided with a long waist-shaped through hole; and also includes a second fastening bolt 13 that passes through the fourth through hole and the long waist-shaped through hole.

[0020] A connecting plate 14 is provided at the top between the two channel steels 4, and the connecting plate 14 and the channel steel 4 are welded; the connecting plate 14 is provided with a plurality of bolt through holes distributed side by side, and a corresponding second through hole is provided on the frame body 2; a third through hole matching the bolt through hole at the end is also provided on the top of the channel steel 4; a shock-absorbing pad 15 is provided on the top surface of the connecting plate 14.

[0021] The upper and lower surfaces of the shock-absorbing pad 15 are both provided with groove hole groups.

[0022] The present application improves the shock absorption performance by arranging a shock-absorbing pad above the connecting plate, thereby reducing vibration and improving the stability of operation.

[0023] like Figure 2 As shown, the length of the channel steel is greater than the length of the frame body.

[0024] like Figure 1 As shown, the fixing bolt passes through the third through hole, the connecting plate and the second bolt hole from bottom to top in sequence, and is finally fastened by a nut, thereby achieving the purpose of fixing the channel steel under the frame body.

[0025] The long waist-shaped through holes at the bottom of the channel steel can be manufactured in the factory without on-site processing.

[0026] In the traditional way, once the wheel axle is installed, its position cannot be adjusted. When the wheel axle installation position may be adjusted due to actual conditions, it is necessary to drill holes again, which is extremely inconvenient to adjust. However, the present application opens a long waist-shaped through hole on the lower surface of the channel steel in the factory, and flexibly adjusts the installation position through the slide groove formed between the U-shaped bending plate and the upper end of the L-shaped fixing plate. Once the position is determined, the L-shaped fixing plate and the channel steel are fixed by the second bolt, making the installation extremely convenient and very convenient for on-site construction. Moreover, the U-shaped bending plate can also improve the installation strength.

[0027] The utility model adopts channel steel, fixing bolts and wheel axle fixing parts to fix the rewinding wheel to the frame body. Compared with the previous fixing method, it is not only easy to install, but also has improved connection reliability, which can make the main engine run more smoothly and reduce vibration, thereby increasing the overall service life and reducing related problems caused by unstable connection.

[0028] The wheel axle fixing part, the wheel axle and the rewinding wheel can be assembled and fixed in the factory or assembled and fixed on site. The wheel axle fixing part and the wheel axle are both provided with fixing screw holes. After the wheel axle is installed on the wheel axle fixing part, a sealing plate is provided outside the wheel axle fixing part and fixed to the wheel axle fixing part and the wheel axle with screws to achieve the fixed installation of the wheel axle.

[0029] The installation process of the utility model is as follows: the channel steel and the connecting plate are welded and fixed, and an adhesive shock-absorbing pad is arranged on the upper surface of the connecting plate, and an opening corresponding to the third through hole and the bolt through hole is provided on the shock-absorbing pad. After the frame body is fixed on the shelf beam, the fixing bolt passes through the third through hole, the bolt through hole, and the second through hole, and then is fastened by a nut to complete the installation of the channel steel group; then one of the axle fixing parts is slid into the bottom of the channel steel, and after adjusting the position, it is fastened by the second bolt and nut, and one end of the rewinding wheel with the axle is installed into the axle installation hole of the axle fixing part, and then another axle fixing part is installed, and the axle end of the other end of the rewinding wheel is inserted into the axle installation hole of the corresponding axle fixing part, and then the sealing plate is fixed to the axle and the axle fixing part by screws.
