Description

Technical Field

[0001] The utility model relates to the field of hoisting equipment, in particular to a telescopic hanging beam. Background Art

[0002] Placing the product in the galvanizing pool for galvanizing is a key step in the galvanizing process. Usually, this process involves using a hanging beam to hang the product in the galvanizing pool. However, as production demand grows, we find that the traditional hanging hole method has some limitations, and only a small number of products can be tied each time, which is inefficient.

[0003] In order to improve efficiency, we considered using chains as an alternative and tying the products on the chain buckles. This method can allow more products to be processed at the same time and improve production efficiency. However, the problem of connecting the chain to the hanging beam also arises. The inconvenience of connection may affect the smoothness and safety of operation.

[0004] In addition, as the number of products increases or the weight difference on both sides of the beam changes, the stability and safety of the beam become the focus. To meet these challenges, we need to add lifting points and adjust the lifting points according to the position of the center of gravity of the product to ensure that the beam remains stable during operation.

[0011] In one embodiment, a hanging plate is connected to the bottom of the main hanging beam, and a plurality of hanging holes are formed on the hanging plate.

[0012] In one embodiment, the hanging hole is T-shaped.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0029] The first fixing hole 4 and the second fixing hole 5 pass through the front and rear sides of the main suspension beam 1 and the telescopic suspension beam 2. The pin 3 is inserted into the first fixing hole 4 and the second fixing hole 5, and both ends protrude outside the main suspension beam 1. The telescopic suspension beam 2 is fixed by the pin 3 so that it can no longer move. In this embodiment, the pin 3 is more convenient to insert and more flexible to use.
