Description

Technical Field

[0001] The utility model relates to the field of elevator machinery manufacturing, in particular to an elevator counterweight frame structure. Background Art

[0002] When the existing elevator modification project is changed from 1:1 to 2:1 structure, it is necessary to add guide wheels to the counterweight frame. The existing ways to add guide wheels are: 1. Replace the counterweight frame. This solution requires replacing the entire counterweight frame, which is costly; 2. Replace the counterweight frame upper beam. This solution requires precise measurement of the connection hole size between the upper beam and the column. For elevator modification, the counterweight frame has been in use for more than ten years. On-site measurement is difficult and the measurement error is large. After the parts arrive at the site, they often need to be rectified on-site, which is time-consuming and labor-intensive. Some counterweight frame upper beams and columns are welded structures and cannot use this solution; 3. Use hanging plates to hang the guide wheels above the counterweight frame upper beam. This solution requires welding the hanging plates on both sides of the hanging plates. The hanging plates are subject to the gravity of the entire counterweight frame, which has high welding requirements.

[0003] In order to solve the above problems, a design scheme of adding guide wheels to the elevator counterweight frame is adopted (1:1 to 2:1). It is necessary to measure the outer width of the upper beam of the counterweight frame. According to the outer width, an adapter is designed and placed on the lower side of the upper beam. The adapter is designed with bolt holes to connect with the guide wheel hanging plates. The guide wheels are installed between the hanging plates for operation. The combination of the adapter and the hanging plates forms a U-shaped part that can drag the counterweight frame. The adapter only needs to be simply welded to the upper beam. This scheme is highly versatile and suitable for counterweight frames of various structures.

[0004] However, in the above-mentioned prior art, the height of the guide wheel cannot be adjusted, resulting in inconvenience in use. Utility Model Content
