Embedded laminated plate balancing block

Abstract

The invention relates to an embedded laminated plate balancing block which comprises a foundation plate block, metal plate blocks and a lifting hook. The foundation plate block is overlaid with the metal plate blocks. The lifting hook is hooked to the upper end of a bolt-shaped installation column. The bolt-shaped installation column penetrates from the lower bottom portion of the foundation plate block upwards to the topmost metal plate block. The portion, on the topmost metal plate block, of the installation column is coaxially sleeved with a pressing plate. The pressing plate is locked to the installation column through a strong locking nut in a threaded meshed mode. The middles of the two sides of the foundation plate block are upwards provided with turn-back barbs which are overturned inwards, and the metal plate blocks overlaid on the foundation plate block are firmly, stably and fixedly installed together. According to the embedded laminated plate balancing block, due to the fact that the two sides of the foundation plate block are upwards provided with the turn-back barbs, the whole balancing block is more stable and is effectively prevented from being loosened and deviated, and the safety performance of the balancing block is improved.

Description

technical field [0001] The invention belongs to the field of elevators, and relates to a balance block used for balancing counterweights of an elevator, in particular to an embedded-mounted stacked plate balance block. Background technique [0002] In engineering industries such as elevator equipment, balance weights are required. With the acceleration of urbanization in recent years, the demand for them is increasing. At present, the balance weights on the market are made of pig iron, scrap steel and other materials, and most of them are long blocks. A suspension hook is fixed in the middle of a piece of metal plate. The disadvantages of this method of balance weight are: 1. The steel hoop binding is easy to cause loosening or even offset, resulting in the loss of stability of the balance weight of the balance weight, which is easy to cause accidents; 2. The metal plates are not fixed, which affects the balance weight. 3. The entire balance weight has no vibration reducti...

Problems solved by technology

The disadvantages of this method of balance weight are: 1. The steel hoop binding is easy to cause loosening or even offset, resulting in the loss of stability of the balance weight of the balance weight, which is easy to cause accidents; 2. The metal plates are not fixed, which affects the balance weight. 3. The entire balance weight has no vibration reduction and buffering, which not only affects the stability of the lifting equipment, but also easily generates noise

[0003] Not only does it consume a lot of metal resources, but the process is more complicated, it needs to consume a lot of energy, the cost is high, the labor intensity is high, and the production environment is harsh
