Description

Technical Field

[0001] The utility model relates to the technical field of section steel production, in particular to a section steel rejecting device. Background Art

[0002] In the current steel production field, inspection benches are usually set up on the steel production line. In order to ensure that the size and tolerance of the finished steel meet the standards and specified range, manual or automated equipment is required to inspect the size and tolerance of the steel on the inspection bench. The steel that does not meet the specified size and tolerance will be recorded and removed and transported through the steel transfer roller later in the assembly line for further grinding, straightening or scrapping.

[0003] The steel transfer roller is a roller transport method. When the steel that needs to be removed and transported is transported to the roller, the roller will transfer it from the assembly line to the required position. However, although the roller transport structure is relatively simple, for production workshops built according to old standards, the roller removal and transfer of unqualified steel with higher standards is not considered, or when the new production line cannot be arranged with steel transfer rollers due to space constraints, due to the lack of corresponding steel transfer rollers, the steel is often hoisted and transferred offline by the overhead crane when it reaches the subsequent workstation of the assembly line. This solution has a low rhythm, is difficult to locate, has high labor intensity for workers, and is prone to omissions.

[0004] Therefore, for steel section production lines that cannot use existing steel section transfer rollers due to site or construction issues, how to design a steel section rejection device to remove steel sections that do not meet the requirements while ensuring that it can adapt to and match the existing steel section production line is a technical problem that needs to be solved by technical personnel in this field.

[0020] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] Figures 1 to 3 The structure of the steel section rejecting device 100 according to an embodiment of the utility model is shown. Figures 1 to 3 As shown, the steel section rejection device 100 may include: at least one transverse chain conveyor 1 arranged in at least one steel section production line and a steel structure platform 2 spanning above the transverse chain conveyor 1, a steel section rejection component 3 installed on the steel structure platform 2, and a control device (not shown in the figure) connected to both the steel section rejection component 3 and the transverse chain conveyor 1, the control device is used to control the steel section rejection component 3 to grab the steel section 4 to be rejected and place it on the steel structure platform 2 when the steel section 4 to be rejected is transported to a predetermined position on the transverse chain conveyor 1, and then control the steel section rejection component 3 to return to its original position.

[0022] When the steel section rejection device 100 of the embodiment of the utility model is working, the control device can track the transportation of the steel section 4 to be rejected according to the real-time production data. When the steel section 4 to be rejected is transported to the predetermined position on the transverse chain conveyor 1 along the normal production line, the control device controls the steel rejection component 3 to operate, and completes the transfer of the steel section 4 to be rejected from the transverse chain conveyor 1 to the steel structure platform 2 to wait for subsequent inspection, grinding or lifting.

[0023] In a preferred embodiment, the transverse chain conveyor 1 is preferably a part of the conveyor roller of an existing steel production line. By arranging a steel structure platform 2 across the top thereof, the arrangement can remove the steel sections 4 to be removed while ensuring the normal operation of the steel production line, while also making full use of the space above this part of the conveyor roller. The steel sections 4 to be removed generated in the steel production line are collected in turn by the steel removal assembly 3 on the upper steel structure platform 2. The steel sections 4 to be removed are collected at a higher place, which is also convenient for subsequent cranes to lift them uniformly.

[0024] The steel section rejection device 100 of the embodiment of the utility model selects a suitable conveyor roller on the existing steel section production line as the rejection point for the steel section 4 to be rejected, and simultaneously arranges a steel structure platform 2 above the conveyor roller. Since the structure platform 2 does not occupy the floor space of the factory building, for the steel section production line that cannot be additionally installed with a steel section rejection device due to insufficient factory space or construction problems, the steel section rejection device 100 of the utility model can better adapt to and match the existing steel section production line without interfering with the normal production rhythm of the existing steel section production line. By accurately controlling the movement of the steel section rejection component 3, the stability, accuracy and efficiency of the transfer of the steel section 4 to be rejected can be guaranteed, while also reducing the labor intensity of the workers.

[0025] In a preferred embodiment, when the number of steel sections 4 to be rejected on the transverse chain conveyor 1 is large, the control device can first control the transverse chain conveyor 1 to stop transportation, and then control the steel section rejection component 3 to grab multiple steel sections 4 to be rejected in turn and place them on the steel structure platform 2.

Through this arrangement, the steel sections 4 to be rejected from one steel section production line can be transported to the first conveyor roller 212 in another steel section production line through the first conveyor roller 212 and the second conveyor roller 72. In this way, the steel sections 4 to be rejected from the two steel section production lines can be on the first conveyor roller 212 in the same steel section production line, so as to facilitate the subsequent unified processing of all the steel sections 4 to be rejected. This arrangement allows the steel sections 4 to be transported off-line without interfering with the normal production line. After subsequent inspection and grinding, the steel sections are returned by the roller conveyor.
