[0002] The counterweight device is a component of the elevator traction system. It is installed in the elevator shaft and connected to the car through the traction rope and the traction wheel. During the movement of the elevator, the counterweight device slides up and down along the counterweight guide rail through the counterweight guide shoe, thereby balancing the weight of the car.
[0003] Existing counterweights are generally provided with protrusions or grooves at both ends for clamping with the counterweight frame. The counterweight is clamped and fixed with the counterweight frame through the protrusions or grooves at both ends, such as the structure in an elevator counterweight frame in patent CN209974076U. In this structure, the installation of the counterweight requires the upper part of the counterweight frame to be disassembled, or the counterweight is tilted so that one end is first clamped with the counterweight frame and then the other end is installed. Since the counterweight is heavy, this installation method is more laborious, especially for the counterweight near the upper end, the installer consumes more physical strength and is inconvenient to use.
[0004] In view of this, research and improvement are carried out on the existing problems, and a detachable elevator counterweight with mortise and tenon structure is provided, aiming to solve the problem and improve the practical value through this technology. Utility Model Content
