The counterweight and car are fixed at both ends of the wire rope and then hung on the pulley driven by the elevator motor. This can effectively balance the weight of the car, ensure smooth operation of the elevator, and reduce the power consumption of the elevator motor.

[0003] The patent specification with announcement number CN211619725U discloses an elevator counterweight block. Each of the counterweight block units can be spliced ​​and stacked to form counterweight blocks of different masses. When the mass of the counterweight block needs to be changed, the number of the counterweight block units can be appropriately increased or decreased to meet actual needs. It has the advantages of flexibility and adjustability; and a plurality of the counterweight block units are spliced ​​with each other in an interlaced manner to achieve a firm connection between the counterweight block units without the need for reinforcement processes such as welding, thereby reducing construction links and improving efficiency.

[0012] As a further description of the above technical solution: the assembly mechanism also includes a zinc block, which is fixed at the bottom end of the assembly shell, and a connecting hole is opened at the top end of the assembly shell. The cooperation of the zinc block plays a cathodic rust prevention role, which can improve the anti-corrosion effect of the counterweight block.

[0013] As a further description of the above technical solution: sliding grooves are opened on both sides of the interior of the placement shell, and sliding blocks are fixed at the positions corresponding to the sliding grooves on both sides of the outer wall of the assembly shell. Through the cooperation of the sliding grooves and the sliding blocks, the assembly shell is prevented from loosening or shifting inside the placement shell, affecting the overall stability of the counterweight block.

Through the placement shell and the limit groove, it is convenient for the assembly shell to slide and be stacked through the limit plate, so that the assembly shell can be quickly assembled according to the weight required by the elevator to improve flexibility or applicability. The sliding of the assembly shell is avoided by the slide groove and the slider to prevent the assembly shell from sliding and deflecting. The zinc blocks of each group of assembly shells correspond to the connecting holes of the lower assembly shell, so as to effectively avoid shaking after stacking and causing the assembly shell to deflect. The zinc blocks and the metal assembly shell are fixed. Zinc is relatively active relative to other metals. When connected with other metals, zinc will corrode first, so as to play a cathode rust prevention method to improve the radiation protection effect. BRIEF DESCRIPTION OF THE DRAWINGS
