Description

Portable driving cam hook replacing device

Technical Field

The utility model relates to the technical field of manufacturing of mechanical equipment in the steel industry, in particular to a device for replacing a hook with a shape like a Chinese character 'shan' for a travelling crane.

Background

In the converter steelmaking process, a travelling crane is generally used for pouring molten iron into a converter, when a main hook of the travelling crane is hung in a molten iron tank and is ready to approach the converter, a hook in the shape of a Chinese character 'shan' of the travelling crane is hung in a tilting mechanism of the molten iron tank, the travelling crane lifts an auxiliary hook so as to drive the molten iron tank to incline, and the molten iron is poured into the converter. The tilting mechanism which is efficiently hung in the hot metal ladle can reduce the smelting period, thereby bringing more steel yield and benefit for enterprises. When the hook with the Chinese character 'shan' shape is used, the hook with the three-character 'shan' shape has the problems of abrasion, deformation and the like, and timely and efficient replacement can ensure that the smelting period is not prolonged, so that the speed of a casting machine cannot be connected, and finally, the accident of machine break is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a portable traveling crane hook replacing device, which can solve the problems that the production efficiency is influenced by the long smelting period caused by the low efficiency of replacing the hook in the conventional traveling crane.

In order to solve the problems, the technical scheme of the utility model is as follows: the portable traveling hook replacing device comprises a vertical supporting beam, an upper supporting beam, a bottom tray, a tray connecting beam and a left protective plate and a right protective plate; 5 bottom trays are uniformly distributed and arranged and welded with the tray connecting beam; the vertical supporting beams for supporting the bottom trays stably are arranged between the two bottom trays, and the two sides of the bottom trays are welded at the bottoms of the 3 uniformly distributed vertical supporting beams; the upper supporting beams are welded on the upper parts of the vertical supporting beams which correspond to each other in pairs between the two bottom trays so as to enhance the stability of the vertical supporting beams; and the left guard plate and the right guard plate are respectively welded on the upper parts of the root vertical support beams on the outer sides of the foremost bottom tray and the rearmost bottom tray, so that the whole device is firm.

3. A portable traveling cam hook exchanging device according to claim 1 or 2, wherein:

in the above technical solution, a more specific solution is: the number of the bottom trays is 5, the length of the bottom trays is 2500 mm, and the width of the bottom trays is 320 mm.

Further: the vertical supporting beam is angle steel, and the height is 1250 millimeters.

Further: the length of the upper support beam is 300 mm; the length of the left guard plate and the right guard plate is 1680 mm.

Due to the adoption of the technical scheme, compared with the prior art, the utility model has the following beneficial effects:

1. by adopting the utility model to replace the Chinese character 'shan' hook, the Chinese character 'shan' hook can be immediately replaced when accidents such as the Chinese character 'shan' hook is inclined or the hook is not hooked when in fault, and the like occur, only one person needs to command the traveling crane, and the traveling crane operator can operate the traveling crane, thereby the replacement is rapid and convenient, and the labor intensity is low; meanwhile, the E-hook with the fault problem is replaced, so that molten iron can be stably fed in front of the converter to achieve normal blowing of the converter, the efficiency is greatly improved, and the steel-making preparation time is effectively shortened.

2. The utility model has simple structure and is basically free from maintenance.

FIG. 2 is a schematic left side view of the present invention;

fig. 3 is a schematic top view of the present invention.

The reference numbers in the figures denote:

1. a vertical support beam; 2. an upper support beam; 3. a bottom tray; 4. A pallet connecting beam; 5. left and right guard plates.

Detailed Description

The utility model is further illustrated with reference to the following figures and examples:

the portable traveling hook changer shown in fig. 1, 2 and 3 includes a vertical support beam 1, an upper support beam 2, a bottom tray 3, a tray connecting beam 4, and left and right guard plates 5. According to the number of the E-shaped hooks, 5 bottom trays 3 are arranged, and the 5 bottom trays 3 are uniformly distributed and arranged and welded with the tray connecting beam 4; a vertical supporting beam 1 for supporting the two bottom trays 3 stably is arranged between the two bottom trays 3, and two sides of each bottom tray 3 are welded at the bottoms of the 3 uniformly distributed vertical supporting beams 1; the upper supporting beams 2 are welded on the upper parts of the vertical supporting beams 1 which correspond to each other in pairs between the two bottom trays 3 so as to strengthen the stability of the vertical supporting beams 1; a left guard plate and a right guard plate 5 are respectively welded on the upper parts of the 3 vertical support beams 1 at the outer sides of the foremost bottom tray 3 and the rearmost bottom tray 3, so that the whole device is firm.

In this embodiment, the number of the bottom trays 3 is 5, the length of the bottom tray 3 is 2500 mm, and the width thereof is 320 mm; the vertical support beam 1 is angle steel with the height of 1250 mm; the upper support beam 2 is 300 mm long; the left and right guard plates 5 are 1680 mm long.

When the hook is used, the old Chinese character 'shan' hook is detached from the bottom tray 3 by the crane, and then the new Chinese character 'shan' hook is directly hung after unhooking, and then the hook is lifted. The vertical supporting beam 1 plays a role in stable supporting, and the left and right guard plates 5 are connected to enable the E-shaped hook to stand up and not to topple over towards two sides. The tray connecting beam 4 is connected with the bottom tray 3 to form a plurality of vacant positions for placing the Chinese-character-shaped hooks. The bottom tray 3 is just connected with the hook which is slowly unloaded by the traveling crane, so that the hook is stably fixed on the bottom tray 3.
