[0002] Stirrups are widely used in the production process of prefabricated parts. For example, stirrups are an important part of the metal skeleton of sleepers. In the mass production of sleepers, stirrups are used in large quantities. How to quickly, efficiently and with high quality realize the processing and production of stirrups is of great significance to the production of prefabricated parts using them.

[0003] In the production process of some stirrups, it is necessary to weld the stirrups to improve the mechanical properties of the prefabricated parts using stirrups. In the actual production process, the steel bars must first be bent into stirrups, and then the stirrups must be welded. In the process of bending the steel bars, the various bending sections of the stirrups after bending may be twisted and deformed, resulting in the bending sections of the stirrups formed by the bending not being on the same surface, making it difficult to meet the welding conditions. Therefore, it is necessary to place the stirrups formed by the bending on the welding workbench and reasonably constrain the stirrups so that they can be welded. Therefore, welding plays an important role in the processing of stirrups. Furthermore, how to achieve automated processing of stirrups places higher requirements on the performance of the welding workbench. Utility Model Content

It should be pointed out that the sleepers in the present application can be selectively sleepers required for railway construction, for example, they can be selectively double-block sleepers, prestressed sleepers, etc. Specifically:

[0071] In the first aspect, the present application provides a welding workbench 1, which is used to constrain the stirrup 6 to a position that meets the welding requirements. The welding workbench 1 includes a bearing platform 11, a clamping unit 12, a first push-pull assembly 13 and a second push-pull assembly 14; the clamping unit 12 is fixed on the bearing platform 11, and the clamping unit 12 is used to clamp the stirrup 6 to the bearing platform 11 in the vertical direction; the first push-pull assembly 13 is installed on the upper surface of the bearing platform 11, and the first push-pull assembly 13 is used to push the first welding section 61 of the stirrup 6 toward the second welding section 62 to the welding position; the second push-pull assembly 14 is installed on the upper surface of the bearing platform 11, and the second push-pull assembly 14 is used to push the second welding section 62 of the stirrup 6 toward the first welding section 61 to the welding position.

As a convertible implementation, the bearing support 111 can also be any structural form that meets the bearing requirements. In specific implementation, the carrying platform 11 and the bearing support 111 can also be selectively integrated.

[0073] It should also be noted that the pressing unit 12 in the present application is not specifically limited, and it can be any pressing unit 12 that can press the welded stirrup 6 onto the bearing surface of the bearing platform 11. In a specific implementation, Figure 4 and Figure 5As shown, the pressing unit 12 includes a telescopic assembly 121 and a pressing member 122; when the telescopic end 1211 of the telescopic assembly extends to a set position, the telescopic assembly 121 drives the pressing member 122 to press the stirrup 6 on the bearing platform 11, and when the telescopic end 1211 of the telescopic assembly retracts to a set position, the telescopic assembly 121 drives the pressing end 1222 of the pressing member 122 to move upward and release the stirrup 6 on the bearing platform 11. It should be further pointed out that the telescopic assembly 121 in the present application can be any assembly that can drive the pressing member 122 to achieve the pressing function. In specific implementation, the telescopic assembly 121 can be selectively one of a pneumatic telescopic cylinder, a hydraulic telescopic cylinder, a screw slider module, a gear rack module, etc. In specific implementation, it is preferred that the telescopic assembly 121 is set as a pneumatic telescopic cylinder, and the pneumatic telescopic cylinder is connected to the pressure gas source (gas pressure tank, gas pump, etc.) through a control valve.

[0074] It should be pointed out that the first push-pull component 13 in the present application is not specifically limited. It can be any component that can act on the first welding section 61 of the stirrup 6 and move to the second welding section 62 of the stirrup 6 to a set welding position. In specific implementation, the first push-pull component 13 can be selectively configured to include one of a pneumatic telescopic cylinder, a hydraulic telescopic cylinder, a screw slider module, a gear rack module, a linear motor, etc. In specific implementation, it is preferred that the first push-pull component 13 is a pneumatic telescopic cylinder. Specifically, Figures 1 to 4 As shown, the cylinder of the first push-pull assembly 13 is fixed on the upper surface of the bearing platform 11, and the telescopic end of the first push-pull assembly 13 can drive the first welding section 61 of the stirrup 6 to move toward the second welding section 62 in the horizontal direction.

[0075] Similarly, the second push-pull assembly 14 in the present application is not specifically limited, and it can be any assembly that can act on the second welding section 62 of the stirrup 6 and move to the first welding section 61 of the stirrup 6 to a set position.

[0076] It should be noted that the "first welding section" in the present application is a section of the stirrup that needs to be welded; similarly, the "second welding section" in the present application is another section of the stirrup that needs to be welded; in the specific implementation, the stirrup is welded to connect the first welding section and the second welding section through the welding unit 8 so that the stirrup is welded into a closed structure.

[0077] It should be explained that the "welding position" in "the first welding section moves toward the second welding section to the welding position" in this application refers to the position where the first welding section is located when the first welding section moves toward the second welding section under the action of external force to meet the stirrup welding requirements. In specific implementation, the external force applied to the first welding section is provided by the first push-pull assembly.

[0078] It is also necessary to explain that the "welding position" in "the second welding section moves toward the first welding section to the welding position" in this application refers to the position where the second welding section is located when the second welding section moves toward the first welding section under the action of external force to meet the stirrup welding requirements.

At the same time, under the action of the welding workbench 1, the constraint time of the bent stirrup on the welding workbench 1 can be effectively shortened, thereby effectively improving the welding efficiency of the stirrup 6. In the specific implementation, the first push-pull assembly 13 and the second push-pull assembly 14 are controlled by the control unit, thereby providing technical support for the automatic positioning of the first welding section 61 and the second welding section 62.

In specific implementation, the third push-pull assembly 15 can be selectively configured to include one of a pneumatic telescopic cylinder, a hydraulic telescopic cylinder, a screw slider module, a gear rack module, a linear motor, etc. In specific implementation, it is preferred that the third push-pull assembly 15 is a pneumatic telescopic cylinder. Specifically, Figures 1 to 4 As shown, the cylinder body of the third push-pull assembly 15 is fixed on the upper surface of the supporting platform 11, and the telescopic direction of the telescopic rod of the third push-pull assembly 15 is perpendicular or substantially perpendicular to the push-pull direction of the first push-pull assembly 13. Under the action of the third push-pull assembly 15, the first straight section 63 of the stirrup 6 can be pushed toward the inner side of the body of the stirrup 6 to a set position.

[0082] Similarly, the fourth push-pull assembly 16 in the present application is not specifically limited, and can be any push-pull assembly that can move the first straight section 63 of the stirrup 6 toward the outside of the main body of the stirrup 6 to a set position.

In a specific implementation, it is preferred that the fourth push-pull assembly 16 is a pneumatic telescopic cylinder.
