Description

Technical Field

[0001] This utility model relates to an improvement of the counterweight structure of an elevator, specifically a counterweight frame for a narrow counterweight in a villa elevator. Background Technology

[0002] The counterweight device of an elevator is a counterweight structure that moves up and down relative to the elevator car. Therefore, the counterweight device also needs to occupy a certain cross-sectional space in the elevator shaft. For the elevator shaft, its cross-sectional area is limited, and it is the optimal choice to leave the main space for the elevator car. The counterweight frame is usually arranged close to the shaft wall. The structure of the counterweight device mainly consists of counterweight guide rails, counterweight frame, and counterweight blocks. The counterweight frame is the main spatial structure. There are also counterweight guide rails on the outside of the counterweight frame, so it requires more space. Therefore, the counterweight frame structure needs to be improved to reduce its thickness and be as close as possible to the shaft wall. 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 counterweight frame for narrow counterweights in villas.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The counterweight frame includes an upper horizontal plate, a vertical frame, and a lower horizontal plate. The upper and lower horizontal plates are both horizontally arranged and located at the upper and lower ends of the counterweight frame, respectively. The vertical frame is arranged opposite to each other on both sides, forming a rectangular frame structure with the upper and lower horizontal plates. Counterweight blocks are set within the frame structure. The upper and lower horizontal plates are both composed of two opposite flat plate structures, with a space between the flat plate structures for clamping the counterweight blocks. The counterweight frame adopts a lightweight structure, reducing the thickness of the structure. The larger surfaces on both sides of the counterweight frame are installed using plate structures. While ensuring structural reliability, it reduces space occupation and the weight of the counterweight frame, making it suitable for elevator types such as villa elevators.

[0005] Furthermore, the planar plate structure of the upper and lower horizontal plates is formed by fixing planar metal plates to the vertical frame. The vertical distance between the planar plate structure of the upper horizontal plate is greater than that of the planar plate structure of the lower horizontal plate, wherein the vertical distance between the planar plate structure of the lower horizontal plate is greater than the thickness of a single counterweight. The planar plate structure is mainly used to restrict the counterweight; its greater thickness than the counterweight restricts lateral movement and improves safety. The upper horizontal plate requires more structural installations, hence the greater distance required.

[0006] Furthermore, a bottom bracket is provided at the bottom of the planar structure of the lower horizontal plate. The bottom bracket is located at the lowest point of the counterweight frame and is fixedly connected to the plate structures on both sides. The bottom bracket can enhance the structural strength of the lower horizontal plate, improve the working load capacity of the counterweight frame, effectively resist working vibration, and improve product quality.

[0007] Furthermore, a counterweight roller is mounted on the upper horizontal plate, and the rotating shaft structure of the counterweight roller is installed through the upper horizontal plate. An axle support plate is also fixedly installed on the outer surface of the upper horizontal plate, and the axle support plate is reinforcedly installed on the lower edge of the rotating shaft structure. The counterweight roller can be directly mounted on the upper horizontal plate, and in conjunction with the axle support plate, it strengthens the structure and achieves the best effect of reducing thickness.

[0008] Furthermore, guide shoes are fixedly installed on the outer edge of the vertical frame. The guide shoes are symmetrically arranged on both sides of the vertical frame, with the guiding parts of the guide shoes facing away from each other. The counterweight guide rails are arranged opposite each other on both sides of the counterweight frame. The counterweight guide rails are also arranged opposite each other on both sides, effectively utilizing the space on both sides and leaving more space for the elevator car.

[0009] Compared with the prior art, this utility model has the following advantages and effects: This design is an improvement on the counterweight structure of an elevator, which mainly reduces the overall thickness of the counterweight, reduces the cross-sectional space occupied by the elevator shaft, leaves more space for the elevator car, improves the utilization rate of shaft space, and is simple to manufacture and easy and reliable to install.
