Description

Technical Field

[0001] The invention relates to the field of section steel production devices, and particularly to a web guiding and conveying device. Background Art

[0002] Compared with traditional concrete buildings, steel structure buildings use steel plates or section steels to replace reinforced concrete, with higher strength and better seismic resistance. And because components can be fabricated in factories and installed on site, the construction period is greatly reduced. Coupled with the fact that steel can be reused, construction waste can be greatly reduced, making it more environmentally friendly and thus widely adopted by countries around the world. Currently, the application of steel structure buildings in high-rise and super high-rise buildings is becoming increasingly mature and gradually becoming the mainstream building technology, which is the development direction of future buildings. In steel structure buildings, large-sized H-section steel is a very commonly used section steel material.

[0003] When carrying out the automated production of large-sized H-section steel, it is necessary to accurately align the flange and the web and accurately convey them to the welding machine. Therefore, when conveying the flange and the web, it is necessary to guide both the flange and the web at the same time. The flange is horizontally placed during conveying, and it is relatively simple during conveying and guiding. While the web is vertically placed during conveying, and it is not convenient for guiding and conveying. Therefore, researching and designing a guiding and conveying device that is convenient for the web conveying and guiding of H-section steel is a research topic worthy of study.

In order to enable the first mounting column 402 and the second mounting column 403 to accurately flip to the vertical position, a support block structure can be arranged at the inner lower ends of the first mounting column 402 and the second mounting column 403, or a vertical baffle can be arranged at the hinge positions of the chassis 401 with the first mounting column 402 and the second mounting column 403. This vertical baffle is located inside the first mounting column 402 and the second mounting column 403.

[0053] When the first mounting column 402 of the web flipping device 4 is unfolded, as Figure 13As shown, the second mounting post 403 can also be deployed in the same way. In order to stably deploy the first mounting post 402 and the second mounting post 403 to the horizontal position, support posts can be vertically arranged on the outer side walls of the first mounting post 402 and the second mounting post 403, or a horizontal stop block can be arranged at the position where the chassis 401 is hinged to the first mounting post 402 and the second mounting post 403, and this horizontal stop block is located outside the first mounting post 402 and the second mounting post 403.

[0054] The second structure of the web flipping device 4 is as Figure 14 shown, and includes a chassis 401, a first mounting post 402, a second mounting post 403, and a first power cylinder 404. The first power cylinder 404 can be any one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The first mounting post 402 is hinged to the chassis 401. The lower end of the cylinder body of the first power cylinder 404 is hinged to the chassis 401, and the top end of the piston rod of the first power cylinder 404 is hinged to the first mounting post 402. The second mounting post 403 is vertically arranged, and the second mounting post 403 and the first mounting post 402 are arranged in sequence along the length direction of the driving roller 103. A second telescopic rod 405 is vertically arranged on the side wall of the second mounting post 403 close to the first mounting post 402. A second guide wheel 406 is horizontally installed at one end of the inner rod 6 of the second telescopic rod 405 away from the second mounting post 403. A second telescopic rod 405 is also arranged on the side wall of the first mounting post 402, and an electromagnet 407 is arranged at one end of the inner rod 6 of this second telescopic rod 405 away from the first mounting post 402. When the first mounting post 402 is in the vertical position, the first power cylinder 404 is located on the side of the first mounting post 402 away from the second mounting post 403. When the first mounting post 402 is in the vertical position, the second telescopic rod 405 arranged on the first mounting post 402 is installed on the side wall of the first mounting post 402 close to the second mounting post 403.

[0055] Compared with the first structure of the web flipping device 4, the main difference in the second structure of the web flipping device 4 is that in this structure, the second mounting post 403 is vertically and fixedly arranged on the chassis 401, which is simpler than the first structure of the web flipping device 4 and omits the second power cylinder 408, resulting in a lower manufacturing cost. However, since the second mounting post 403 cannot be rotated and deployed, it is not convenient to directly horizontally hoist and place the wing plate on the driving roller 103 and the driven roller 104 of the conveying device 1 where the web flipping device 4 is arranged, and it is not very convenient to use.

[0056] The working principle of this embodiment: Compared with Embodiment 2, this embodiment is additionally provided with a web flipping device 4. When this embodiment is in use, as Figure 9 and Figure 10As shown in the figure, multiple conveying devices 1, multiple web guiding devices 2, multiple flange guiding devices 3 and multiple web turning devices 4 need to be used together. The conveying devices 1, web turning devices 4 and flange guiding devices 3 are alternately arranged in multiple groups in the same direction, and then, along the above-mentioned arrangement direction, the conveying devices 1, web guiding devices 2 and flange guiding devices 3 are alternately arranged in multiple groups. Since it is not easy to vertically lift the web, when connecting the web and the flange in a T-shaped structure, the web is first horizontally lifted. At this time, as Figure 11 shown, the first mounting columns 402 of each web turning device 4 rotate and unfold to the horizontal position, and the web is horizontally lifted onto the electromagnets 407 arranged on the first mounting columns 402 of each web turning device 4. The web is sucked by the electromagnets 407, and then the first power cylinder 404 is started to turn the web to the vertical position so that it is vertically placed on the flange placed on the driving roller 103 and the driven roller 104 of the conveying device 1. Therefore, through the setting of the web turning device 4, it is not necessary to vertically lift the web, making it more convenient to set the web and the flange in a T-shaped structure.

[0057] Embodiment 4

[0058] Compared with Embodiment 3, this embodiment is additionally provided with a pressing device and a detection device. The structure of the pressing device is as shown in Figure 15 and Figure 16 shown, and it includes an n-shaped frame 9, a pressing cylinder 10, a pressing wheel 11, a sliding seat 12 and a mounting block 13. The n-shaped frame 9 is vertically arranged, the pressing cylinder 10 is vertically arranged at the upper end of the n-shaped frame 9, and the piston rod of the pressing cylinder 10 extends downward. The lower end of the piston rod of the pressing cylinder 10 is connected to the upper end of the sliding seat 12. Guide grooves are arranged along the height direction on the inner walls of the two vertical parts of the n-shaped frame 9, and the two ends of the sliding seat 12 are respectively arranged in the guide grooves of the two vertical parts of the n-shaped frame 9. The length direction of the sliding seat 12 is the same as the length direction of the driving roller 103. A horizontal sliding groove is arranged along the length direction on the sliding seat 12, the mounting block 13 is arranged in this horizontal sliding groove, the lower end of the mounting block 13 is located below the sliding seat 12, and the pressing wheel 11 is installed at the lower end of the mounting block 13. A rectangular through hole 1201 leading to its horizontal sliding groove is arranged along the length direction on the side wall of the sliding seat 12. A threaded hole is arranged on the side wall of the mounting block 13 corresponding to the rectangular through hole 1201, and a second fixing bolt 21 is installed in this threaded hole, and the rod part of the second fixing bolt 21 passes through the rectangular through hole 1201. The position of the mounting block 13 in the horizontal sliding groove of the sliding seat 12 can be fixed by the second fixing bolt 21. The pressing cylinder 10 can drive the pressing wheel 11 to move up and down through the sliding seat 12.

[0059] When producing H-beams, the T-shaped structure composed of the web and the flange needs to be welded at the joint. During welding, the T-shaped structure composed of the web and the flange is an inverted T shape, with the web on the upper end face of the flange. To ensure the welding quality, a pressing device needs to be set at the end of the conveyor and also at the front end of the assembling machine. The pressing wheel 11 of the pressing device presses on the upper end of the web, making the web and the flange in close contact. Therefore, by setting the pressing device, the welding quality of the web and the flange can be effectively guaranteed during the welding of the web and the flange. In addition, the pressing wheel 11 of this pressing device can also be adjusted in position along the length direction of the sliding seat 12, improving the applicability of the pressing device.

[0060] As Figure 17 and Figure 18 shown, the detection device includes a third telescopic rod 14 and U-shaped clamping plates 15 at both ends of the third telescopic rod 14. Mounting bolts 16 are provided on the upper end wall of the U-shaped clamping plates 15. The third telescopic rod 14 is fixedly installed on the frame 101 of the conveying device 1 through the U-shaped clamping plates 15 and the mounting bolts 16. After installation, the length direction of the third telescopic rod 14 should be perpendicular to the length direction of the driving roller 103. Two sleeves 17 are sleeved on the third telescopic rod 14, and a locking bolt 18 is provided on each sleeve 17. The sleeve 17 can slide along the third telescopic rod 14. Tightening the locking bolt 18 can fix the sleeve 17. An L-shaped mounting bracket 19 is provided on the outer wall of the sleeve 17, and a proximity switch 20 is installed on the L-shaped mounting bracket 19. The proximity switch 20 is electrically connected to the motor of the conveying device 1 through a controller.

[0061] To accurately and quickly align the web and the flange, when the horizontally placed web is flipped onto the flange, the two ends of the web and the two ends of the flange should be made as aligned as possible. After the web is placed, when the flange is conveyed, the flange is detected by the detection device. When the first proximity switch 20 detects the flange, the motor of the conveying device 1 is controlled by the controller to decelerate. When the second proximity switch 20 detects the flange, the motor of the conveying device 1 is controlled by the controller to stop. At this time, the flange can accurately stop at a certain position. Therefore, by setting the position of the sleeve 17 on the third telescopic rod 14, the stop position of the flange can be accurately controlled. In this way, the two ends of the web and the two ends of the flange can be accurately aligned. Therefore, through the setting of the detection device, the two ends of the web and the two ends of the conveyed flange can be accurately aligned before the web is flipped, enabling the flipped web and the flange to be accurately and quickly aligned.
