Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a spliced ​​counterweight block and a pressing device thereof. Background Art

[0002] Elevator counterweights play an important role in elevator systems. Their main functions include: 1) Balancing the weight of the elevator: The counterweight helps maintain the weight balance between the elevator car and the counterweight frame, ensuring that the elevator can move freely up and down between different floors. 2) Stabilizing the operation of the elevator: By reducing the load on the elevator motor, the counterweight helps to keep the center of gravity of the elevator stable, thereby improving the stability of the elevator operation. 3) Saving electricity: Since the counterweight can reduce the load on the elevator motor, a lot of electricity costs can be saved, which is a significant advantage especially for long-term operation of elevators. 4) Reducing vibration and noise: The presence of the counterweight can reduce the vibration and noise of the internal machinery of the elevator, providing passengers with a more comfortable riding experience. 5) Protecting the safety of passengers and equipment: When an abnormal situation occurs in the elevator, such as a break in the machine room or cable, the counterweight can reduce the speed of the elevator stalling and protect the safety of passengers and equipment.

[0003] The size of the counterweight will vary greatly depending on the track gauge. In particular, as cost control becomes increasingly stringent, more and more counterweights with non-standard sizes are being produced to meet demand, further increasing the pressure on product production and inventory. Finding a counterweight that can meet the needs of different track gauges has become an important need. In addition, when the counterweight track gauge needs to be designed to be very large, the counterweight will become very long. An overly long composite counterweight will cause cracks on the surface, and its strength will also be reduced, with a high chance of damage during on-site installation. Considering the manufacturing cost, the height of the counterweight will be designed to be relatively large, which will cause the overall weight of the counterweight to be heavier, making on-site handling and installation more difficult. In addition, due to the inconvenience of handling, the overly heavy counterweight will make the installers more susceptible to squeezing injuries from the counterweight.

[0004] To this end, the patent specification with publication number CN220201115U discloses a spliced ​​counterweight block, including a counterweight frame, a mounting groove is provided in the middle thereof; a plurality of full steel plate counterweight blocks are arranged in the mounting groove; a plurality of cement counterweight blocks are arranged in the mounting groove; a plurality of half steel plate counterweight blocks are arranged in the mounting groove; the cement counterweight blocks and the half steel plate counterweight blocks can be spliced ​​and stuck in the mounting groove. According to the load-bearing requirements of the elevator car, calculations are performed to obtain the appropriate counterweight weight, and a plurality of full steel plate counterweight blocks, a plurality of cement counterweight blocks and a plurality of half steel plate counterweight blocks are mixed and used in a stacking and splicing manner to meet the counterweight requirements.

[0005] However, this type of spliced ​​counterweight block still has some shortcomings when used. First, there is no anti-detachment structure between the counterweight blocks after splicing to prevent them from detaching at will, resulting in poor splicing connection reliability; second, there is no structure that facilitates transportation. Therefore, it is necessary to optimize and improve its structure. Utility Model Content
