Problems solved by technology
[0002] In the production process of heavy beams (such as box girders and I-beams used for erecting bridges and hoisting machinery, etc.), they need to be turned over for processing. Whether it is domestic or foreign, the long-term practice is: by using It can be realized by means of binding, hanging lug in-situ flipping, steel frame flipping, mechanical rotation, and aerial hoisting. The existing flipping methods are all forced. Through this forced method, It is very difficult to overturn the extremely heavy beam. The biggest problems of the existing methods are: large investment, low efficiency, poor safety, and inconvenient operation

Embodiment Construction
[0032] Embodiments of the present invention are described in detail below:
[0033] Such as Figure 1 to Figure 3 As shown, a heavy beam active tumbler includes a tumbler 10 and a base 20, the lower surface of the tumbler 10 has an arc-shaped rolling surface 11, the upper surface of the tumbler 10 has a bearing surface 12, and the rolling surface 11 The two sides of the two sides are upturned and are respectively connected with the two sides of the bolster surface 12.
[0034] Wherein, the rolling surface 11 includes a first plane section 111, a first arc section 112, a second plane section 113, a second arc section 114, a third plane section 115, and a first plane section 111 which are successively connected. 1. The third plane section 115 is respectively connected to both sides of the bolster surface 12, the second plane section 113 is located in the middle of the bottom of the turning body 10, and the first arc section 112 and the second plane section 113 form a The secon...

The invention discloses an initiative overturning device and an overturning method for a heavy beam. The overturning device comprises an overturning body; an arc-shaped rolling surface is arranged on the lower surface of the overturning body; a bearing beam surface is arranged on the upper surface of the overturning body; and two sides of the rolling surface are upwards warped and are respectively connected with two sides of the bearing beam surface in a bearing way. The initiative overturning device and the overturning method for the heavy beam are very simple in structure, can effectively reduce the investment, and have the advantages of being high in efficiency, safe and reliable, and convenient for operation.
Description
technical field [0001] The invention relates to a heavy beam active turning device and a heavy beam turning method. Background technique [0002] In the production process of heavy beams (such as box girders and I-beams used for erecting bridges and hoisting machinery, etc.), they need to be turned over for processing. Whether it is domestic or foreign, the long-term practice is: by using It can be realized by means of binding, hanging lug in-situ flipping, steel frame flipping, mechanical rotation, and aerial hoisting. The existing flipping methods are all forced. Through this forced method, It is very difficult to overturn the extremely heavy beam. The biggest problems of the existing methods are: large investment, low efficiency, poor safety, and inconvenient operation. Contents of the invention [0003] Based on this, the present invention overcomes the defects of the prior art and provides a heavy beam active overturner and a heavy beam overturning method. The presen...
