Description

Turning mechanism and turning method for section steel

The invention relates to the technical field of section steel processing, in particular to a section steel turning mechanism and a turning method.

Shaped steel can be divided into H-shaped steel, I-shaped steel, channel steel, U-shaped steel, etc. according to their cross-sectional shapes. Because various types of steel have the advantages of strong bending resistance, easy construction, and reduced costs, they are widely used in construction or large machinery foundation structures. Because the general section steel has a certain length in use, in order to avoid the section steel from affecting the structural strength due to its length, a certain number of reinforcing ribs are usually welded in advance, or the overlap structure must be welded in advance because of the need for overlap .

Regardless of whether it is a reinforcing rib or an overlap structure, the current processing method is to first use a crane to lift the section steel to a predetermined location. During welding or processing, if there is a need to turn over, you also need to use a crane. For example, a belt or cable can be connected near the two ends of the section steel, and after the section steel is suspended by a crane, the belt or cable rotates, thereby driving the section steel to turn over. This method is not only time consuming, but also costly.

In addition, there is also an iron plate clamp used in conjunction with a crane to lift the profile steel. However, the clamping force of the iron plate clamp on the steel bar is not good, so the process of hanging and turning the steel bar has high danger.

The purpose of the present invention is to solve the shortcomings of the prior art, such as the inconvenience of turning the profile steel, the danger of operation, and the large amount of manpower.

An object of the present invention is to provide a turning mechanism and a turning method for a profile steel, which have a low space occupation rate, so that the turning mechanism is suitable for a small space.

An object of the present invention is to provide a turning mechanism and a turning method for a profile steel, which have the effect of less manpower for operation.

In order to achieve the above-mentioned object and effect, the turning mechanism and turning method disclosed in the present invention are a suspension turning device including a turning device combined with a turning wheel; and a suspension belt is wound around the turning wheel for hanging the profile steel, And the hanging position of the suspension belt to the section steel is adjacent to the central position of the section steel.

In this way, the suspension overturning device lifts the section steel, so that one or two ends of the section steel leave the placement device to form a suspension shape; the overturning device outputs a torque to rotate the suspension belt to cause the section steel to turn over; the section steel follows the suspension The hanging and overturning device is downwardly displaced and can be returned to the placing device.

According to the above description, the present invention allows the profile steel to be turned at an angle, and the profile steel can be returned to the placement device as the suspension flip device is displaced downward, so that the profile steel can be easily, quickly and stably flipped. effect.

Because only a combination of a single suspension turning device and a suspension belt is used, an operator can take care of the entire turning mechanism and process, and achieve the effect of less manpower.
