Description

Steel grating hot-dip galvanized spreader

technical field

The utility model relates to a hot-dip galvanized hanger, in particular to a hot-dip galvanized hanger for steel gratings.

Background technique

At present, most of the international and domestic steel grating hot-dip galvanizing in the steel grating industry adopts the vertical plating process. The so-called vertical plating process is the well-known galvanizing process commonly used in the steel grating industry. The hanger used in this process is the hook. During operation, the hook catches a corner of the grating, lifts it slowly and puts it into the galvanizing pot for galvanizing operation) The characteristics of this process are easy to operate, and the number of workpieces put into the galvanizing pot is large each time. Its disadvantage is that the uniformity of the galvanized layer of the steel grating is poor, the gap between the lowest point and the highest point is 35-45um, and it is difficult to scrape the dust, resulting in poor appearance quality of the workpiece surface. This makes in order to ensure the minimum thickness of the galvanized layer, the thickness of some zinc layers greatly exceeds the standard, increasing zinc consumption. Due to the difficulty of dust scraping, the labor cost of the subsequent finishing process is increased. Some export products are difficult to meet the customer's requirements after finishing, causing foreign customers to raise quality objections or even claim for compensation.

Contents of the invention

In order to overcome the shortcomings of the prior art, the utility model provides a steel grating hot-dip galvanized hanger, which has a simple mechanism, uniform galvanized steel grating, easy to scrape dust and difficult, and good visual quality.

The technical solution adopted by the utility model to solve the technical problem is: the upper part of the sling is hinged with a sling, and the lower sides of the sling are respectively hinged with a hook through a rope or a chain, and the hook hooks the steel grating at the bottom.

There are three hinged hooks on both sides of the lower side of the spreader through ropes or chains, two on the left and one on the right.

The number of hooks hinged by ropes or chains on both sides of the lower side of the sling is four, two on the left and two on the left.

The utility model has the advantages of simple mechanism, uniform galvanized layer of steel grating, easy to scrape ash, and good visual quality.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a structural representation of the utility model;

Fig. 2 is the first embodiment of the bottom view of the utility model;

Fig. 3 is the second embodiment of the bottom view of the utility model.

Detailed ways

As shown in Figure 1, the upper part of the sling 2 is hinged with the sling 1, and the lower sides of the sling 2 are respectively articulated with the hook 4 through the rope or chain 3, and the hook 4 hooks the steel grating 5 laid flat on the ground floor.

U-shaped clips 6 are placed between the steel gratings 5, which not only reduces adhesion and reduces the difficulty of finishing, but also makes it difficult to fall into the pot to reduce the formation of zinc slag and reduce zinc consumption.

As shown in FIG. 2 , there are three hinged hooks 4 on both sides of the lower side of the spreader 2 through ropes or chains 3 , two on the left and one on the right.

As shown in FIG. 3 , there are four hinged hooks 4 on both sides of the lower side of the spreader 2 through ropes or chains 3 , two on the left and two on the left and right.
