Description

Movable auxiliary turning device and method suitable for large volume and weight components

technical field

The invention relates to the related technical field of industrial equipment, in particular to a movable auxiliary turning device and method suitable for large-volume and heavy components.

Background technique

In recent decades, with the vigorous development of the national economy, the quality of scientific research in my country has also been continuously improved. In order to increase the accuracy and credibility of the test model, the proportion of the model is getting closer to the actual situation, so more and more large steel components, concrete components or composite components are fabricated, hoisted and processed.

When lifting a large-volume and heavy-weight component, the lifting wire rope usually does not coincide with the geometric central axis of the component, which will cause the center of gravity of the component to be naturally biased to one side, and the component can only be lifted by a gantry crane, and cannot be turned over naturally. In addition, in order to avoid swinging and transient changes of components in the air, and from the perspective of ensuring personal safety during the overturning process, an auxiliary overturning device must be used to control the displacement of the component overturning in order to overturn safely.

In short, the overturning movement of the component includes two parts: the vertical movement with the gantry crane and the overturning movement with the aid of the auxiliary overturning device.

However, in the prior art, there is no auxiliary device that is suitable for large volume and mass and can control the relative movement of components, especially for components such as cuboids or cubes to turn over.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and provide a movable auxiliary turning device suitable for large-volume and heavy components. By designing a brand-new structure, the device can more conveniently realize the turnover of large-volume and high-quality components.

In order to achieve the above object, the present invention adopts the following technical solutions:

A movable auxiliary turning device for large volume and weight members, comprising:

Main support for carrying components;

One end of the main bracket is equipped with supporting wheels;

There is an overturning rope traction device inside the main bracket;

The overturning rope traction device realizes the overturning of the component by pulling the overturning rope under the cooperation of the hoisting equipment.

Preferably, the main bracket is an H-shaped steel bracket.

Preferably, one end of the main support without supporting wheels is in contact with the ground.

Preferably, the upper surface of one end of the main bracket without supporting wheels is fixedly connected with the auxiliary bracket to limit the sliding of the components.

Preferably, the auxiliary bracket includes fixedly connected vertical and oblique H-shaped steel.

Preferably, the oblique H-shaped steel forms a V-shaped angle with the vertical H-shaped steel.

Preferably, guide wheels are fixedly connected to the vertical H-shaped steel, and the groove portion of the vertical H-shaped steel and/or the oblique H-shaped steel is a space for accommodating the turning rope.

Preferably, there is a rubber cushion layer on the main bracket.

Preferably, the overturning rope traction device is an inverted chain or an electric hoist.

While providing the above-mentioned structural solution, the present invention also provides a method for using the above-mentioned device to turn over components, which mainly includes the following steps:

A. Lift the component vertically;

B. Move the main bracket to the bottom of the component, and limit the support wheel;

C. One end of the overturning rope is hung on the upper part of the component, and the other end is hung on the overturning rope traction device;

D. When the overturning rope is pulled by the overturning rope traction device, the force on the upper part of the component will be offset, and the overturning of the component will be completed as the overturning rope is continuously pulled.

The beneficial effects of the present invention are:

(1) The gravity of the large-volume and high-mass component is decomposed into two through the device, and through the supporting force of the two brackets and the pulling force of the gantry crane, during the overturning process, the supporting force of the two brackets reduces the bearing capacity of the gantry crane The force reduces the burden of overturning heavy components and saves equipment investment.

(2) The component is always supported by the two supports during the entire overturning process, which avoids the swing of the component in the air, ensures the safety of workers during the overturning process, and changes the center of gravity of the component.

(3) During the overturning process, the traction rope provides tension to the upper part of the component, and the lower part of the component relies on the friction between the component and the foot pad to restrict the movement of the component, so that the downward pulling force becomes the overturning force applied to the component.

(4) The auxiliary bracket is H-shaped steel. Under the action of the guide wheel, the guide wheel guides and the groove inside the H-shaped steel can prevent the overturning rope from clinging to the surface of the component and causing difficulty in overturning.

(5) After the completion, the oblique and vertical H-shaped steel supports can be removed. The installation, operation and disassembly of the whole device are convenient, safe, fast, practical and convenient, and convenient for transportation and movement.
