Description

Technical Field

[0001] This utility model relates to an improvement in the counterweight structure of an elevator, specifically a steel plate bending counterweight. Background Technology

[0002] The counterweight frame is a counterweight structure that moves up and down with the elevator car. The counterweight frame is usually made of steel profiles, which are welded and installed on the basis of the steel structure. However, steel profiles are a relatively shallow material with poor dimensional accuracy. There will be more errors during production and installation, which is not conducive to production and processing. In addition, there are certain differences in the overall dimensions of the counterweight frame. During installation, more debugging is required, which is not conducive to improving production quality and construction efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a steel plate bending counterweight frame.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The counterweight frame includes an upper crossbeam, an inner straight beam, an outer straight beam, and a lower beam. The upper crossbeam, outer straight beam, and lower beam together form a rectangular frame structure. An inner straight beam is vertically arranged in the middle of the frame structure. The upper crossbeam, inner straight beam, outer straight beam, and lower beam are all made of bent steel plates. The space between the inner and outer straight beams is set as a fixed space for installing counterweight blocks. A counterweight wheel mounting position is provided on the upper crossbeam, and a counterweight sheave is installed at the counterweight wheel mounting position. The counterweight frame as a whole adopts a frame structure formed by the combination of multiple components. Counterweight blocks are loaded in the counterweight frame to form a counterweight opposite to the elevator car. The main structure of the counterweight frame uses bent steel plates, which can be laser-cut, improving production efficiency, producing products with high processing precision, good dimensional accuracy of the counterweight frame, convenient installation, and less prone to structural interference problems.

[0005] Furthermore, the upper crossbeam includes two opposing upper beam bodies. Each upper beam body is bent to form a "U"-shaped cross-section. The openings between the upper beam bodies face outwards and away from each other. Connecting holes are provided at both ends of the upper beam bodies, connecting to the outer straight beam. An installation hole is provided in the middle of the upper beam body, connecting to the inner straight beam. The counterweight pulley mounting position is located on the lower edge of the upper beam body, and a wheel frame fixing hole is provided. A "U"-shaped rod is installed on the wheel frame fixing hole. A side baffle is provided on the outer edge of the counterweight pulley, and an upper baffle is provided above the counterweight pulley mounting position. The upper crossbeam is the main installation location for the running structure. The counterweight pulley is fixed to the upper crossbeam by a wheel frame. The main body of the wheel frame is a "U"-shaped rod used to fix the shaft of the counterweight pulley. The side baffle and upper baffle demarcate and protect the perimeter of the pulley, improving operational safety.

[0006] Furthermore, the outer straight beams are respectively arranged on both sides of the counterweight frame. The outer straight beams are bent into a "U"-shaped cross-section structure, with their open sides facing the inner side of the counterweight frame. Both the upper and lower ends of the outer straight beams are provided with connecting holes. The upper connecting hole connects to the upper crossbeam, and the lower connecting hole connects to the lower beam. The middle section of the outer straight beam also has multiple sets of positioning holes of different heights. Positioning plates are installed on the positioning holes to position and fix the counterweight blocks. The outer straight beams are the outer structure of the entire counterweight frame. Their open side faces inward, which can be used to clamp the counterweight blocks and prevent them from laterally dislodging. Positioning plates can be installed on the positioning holes to position and fix counterweight blocks of different heights, preventing longitudinal movement.

[0007] Furthermore, the inner straight beam is configured as two parallel structures, bent into a "U"-shaped cross-section, with its open side facing the outer straight beam. Mounting holes are provided at both the upper and lower ends of the inner straight beam; the upper mounting hole connects to the upper crossbeam, and the lower mounting hole connects to the lower beam. Multiple sets of positioning holes at different heights are provided in the middle section of the inner straight beam. The open side of the inner straight beam faces the outer straight beam, forming a counterweight fixing structure with the outer straight beam. This facilitates the installation of the short-side counterweight, effectively improving the flexibility of the counterweight. The positioning holes are also used to fix the positioning plate, providing longitudinal limitation for the counterweight.

[0008] Furthermore, the lower beam comprises two parallel structures, each with bottom connectors at its bottom and sides. These connectors fix and maintain the spacing between the lower beams. Both ends of the lower beam have connection holes for connecting to the outer straight beam, and the middle of the lower beam has mounting holes for connecting to the inner straight beam. The lower beams employ two opposing, straight structures with bottom connectors at their sides and bottom, ensuring consistent spacing within the counterweight frame and creating a stable space to accommodate the counterweight, supporting its load and stabilizing the overall center of gravity of the counterweight frame.

[0009] Compared with the prior art, this utility model has the following advantages and effects: This design is an improvement on the elevator counterweight structure. It is a counterweight frame whose main components are all bent parts, which is suitable for mass production. The produced products have high dimensional accuracy, are easy to install and position, improve production efficiency and product quality, and improve the installation efficiency on the construction site.
