Problems solved by technology

[0004] In actual use, affected by the external environment, such as high humidity in the shipping environment and wind and rain in the road transportation environment, coupled with repeated opening and closing for a long time, it will inevitably damage the more fragile connection parts. That is, certain damages are caused to the hinge part. The existing hinges for containers have the following deficiencies: 1. The existing hinges for containers generally adopt a welding connection process. Due to the limitation of the installation location and the During the opening and closing process, the d

Embodiment 1

[0028] see figure 1 , a hot-rolled steel door hinge device for containers in the figure, including a base 1, a slot 2, a box body 3, lifting lugs 4 and a door panel 5, and a slot is symmetrically opened in the center of one side of the base 1 2, and the upper surface of the base 1 is fixedly installed with a box body 3, and the edge of the upper surface of the box body 3 is symmetrically fixed and installed with lifting lugs 4, and one side of the box body 3 is symmetrically rotated and installed with a door panel 5, and the door panel 5 A hinge mechanism 6 with multiple structural levels is installed between the box body 3 .

[0029] In the main body of the device, the slot 2 provided on the base 1 can facilitate the connection of transfer parts such as forklifts and the device, and the lifting lug 4 is convenient for hoisting the device as a whole, which can meet the requirements for transferring the device as a whole. The hinge mechanism 6 Realize the rotation opening and ...

Embodiment 2

[0040] Such as Figure 5 with Image 6 As shown, the difference between this embodiment and Embodiment 1 is that the base 61 is equidistantly provided with first post grooves 611 on the side close to the box body 3, and the first post grooves 611 are sequentially connected with first guide channels 612, and the chains The side of the plate 67 close to the door panel 5 is equidistantly provided with second column grooves 673 , and the second column grooves 673 are sequentially connected with second guide channels 674 .

[0041]The installation of the hinge mechanism 6 firstly welds the base 61 and the box body 3. During welding, the solder flows into the first column groove 611 from the seam of the base 61 and the box body 3 in a hot-melt state, and passes through the first guide flow. The channel 612 makes the plurality of first column grooves 611 filled with solder, and after cooling, a uniform multi-point column connection structure is formed between the base 61 and the box...

Embodiment 3

[0044] Such as Figure 7 As shown, the difference between this embodiment and the first embodiment is that ribs 672 are symmetrically fixed on one side of the groove 68 on the chain plate 67 .

[0045] This increases the connection transition level between both sides of the groove 68 and the surface of the chain plate 67 , further improving the shear strength of the chain plate 67 .

Abstract

The invention discloses a hot-rolled profile steel door hinge device for a container. The hot-rolled profile steel door hinge device comprises a base, slots, a container body, lifting lugs and a door plank. The device provided by the invention is improved on the structure of a hinge mechanism and has the following advantages: firstly, a uniform honeycomb-shaped connecting structure is arranged at a welding position, and the fastening degree of the connection between the base and the container body and the connection between a chain plate and the door plank can be improved by utilizing the characteristic that the hexagonal honeycomb-shaped structure is stable, so that the possibility that a welding part falls off is reduced under the condition of long-term rotation; secondly, due to the formation of a groove and the step-shaped characteristic of the groove, the dead weight of the chain plate can be reduced firstly, and the extrusion stress of the dead weight on a connecting part is reduced; thirdly, the rigidity of the chain plate is improved due to the formation of the groove; and in addition, the structural layers of the chain plate are increased due to the step-shaped transition of the groove, and stress transmission can be dispersed through inclined planes in steps, so that the purpose of improving the strength of the chain plate is achieved.

Description

technical field [0001] The invention relates to the technical field of hinges, in particular to a hot-rolled steel door hinge device for containers. Background technique [0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow relative rotation between them. The hinge can be composed of movable components or foldable materials. [0003] For a container, sufficient strength and rigidity are required to meet the loading requirements of the cargo, especially as a door hinge part connecting the door frame and the box body, it needs sufficient strength to ensure long-term and smooth use. [0004] In actual use, affected by the external environment, such as high humidity in the shipping environment and wind and rain in the road transportation environment, coupled with long-term repeated opening and closing, it will inevitably damage the more fragile connection parts. That is, certain damages are caused to the hinge part. The existing hi...
