Description

Technical Field

[0001] The utility model relates to the technical field of subway stations, in particular to a welding auxiliary device for rain canopies at entrances and exits of subway stations. Background Art

[0002] With the rapid growth of the domestic economy, the pace of urbanization is accelerating, and the pressure of road traffic is increasing. The demand for the construction of subway stations and their entrance and exit canopies is also rising. However, subway entrances and exits are often located at busy traffic nodes in the city, with complex construction environments, tight time, and strict requirements on environmental protection, safety, quality, etc. The traditional component construction method has been unable to meet the needs of modern urban construction due to its large amount of on-site welding, long construction period, and serious material waste.

[0003] In the existing construction of steel structure canopies at the entrances and exits of subway stations, an assembly method is usually used, that is, most of the processing and welding work is transferred to a specific place for completion, and only simple assembly work is required on site. However, when welding the vertical beams and horizontal beams of the canopy assembly unit together, people usually place the vertical beams and horizontal beams on the ground so that the two are in a perpendicular state to each other, and then weld them. When welding the welding points close to the ground, the vertical beams and horizontal beams need to be erected or turned over so that the welders have enough space to perform the welding work. This method makes the welding work very inconvenient. Therefore, a welding auxiliary device for subway station entrance canopies is proposed, which can facilitate good welding of the contact surfaces of the vertical beams and the horizontal beams.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] A welding auxiliary device for subway station entrance and exit canopy, such as Figure 1-Figure 5 The first embodiment of the utility model is shown, including: a placement unit 1, used for placing a crossbeam steel 5; two crossbeam fixing mechanisms 2, respectively arranged on both sides of the placement unit 1, for limiting the crossbeam steel 5; two vertical beam fixing mechanisms 3, respectively arranged on both sides of the placement unit 1, for limiting the vertical beam steel 6; the crossbeam fixing mechanism 2 includes at least one first slide rail 21 fixedly connected to the placement unit 1, a first slider 22 slidably connected to the first slide rail 21, a first clamping plate 23 fixedly connected to the first slider 22, and a driving component 24 for driving the first clamping plate 23 to move; the vertical beam fixing mechanism 3 includes at least one second slide rail 31 fixedly connected to the placement unit 1, a second slider 32 slidably connected to the second slide rail 31, a second clamping plate 33 fixedly connected to the second slider 32, and a driving unit for driving the second clamping plate 33 to move.

[0030] It can be understood that the operator first places the crossbeam steel 5 on the placement unit 1, and then starts the driving assembly 24, so that the two first clamping plates 23 move toward each other to clamp and limit the crossbeam steel 5, and then the operator can use the crane to lift the vertical beam steel 6, and then place the vertical beam steel 6 to the preset position for welding with the crossbeam steel 5, and make the vertical beam steel 6 and the crossbeam steel 5 in a mutually perpendicular state. After adjusting the position, the operator can operate the driving unit, and the driving unit drives the two second clamping plates 33 to move toward each other, and the second clamping plates 33 move toward each other to clamp and limit the vertical beam steel 6, and then the operator can The welding work is performed at the contact point so that the two are welded together, wherein the crossbeam steel 5 is clamped and limited by the two first clamping plates 23, so that the crossbeam steel 5 is not easy to move during welding, and the vertical beam steel 6 is placed vertically on the crossbeam steel 5. When the operator performs welding, the welding points can be welded at one time, and there is no need to adjust the positions of the vertical beam steel 6 and the crossbeam steel 5 in the middle, so that the welding work is fast and convenient. The vertical beam steel 6 is clamped and fixed by the second clamping plate 33, which can avoid the collapse of the vertical beam steel 6 to cause unsafe factors, and can ensure that the vertical beam steel 6 is not easy to move during welding.

[0031] The placement unit 1 includes a base plate 11 , two vertical plates 12 fixedly connected to the base plate 11 , and a plurality of first rollers 13 rotatably connected between the two vertical plates 12 . The first slide rail 21 and the second slide rail 31 are fixedly connected to the base plate 11 .

[0032] Among them, the operator can place the crossbeam steel 5 on the first roller 13. Since the canopy assembly unit generally requires welding multiple vertical beam steels 6 on a crossbeam steel 5, through the setting of the first roller 13, after welding a vertical beam steel 6, the operator can push the crossbeam steel 5 to move so that the next crossbeam steel 5 welding position is located directly below the second clamping plate 33.

[0033] A plurality of second rollers 25 are rotatably connected to the opposite sides of the two first clamping plates 23 .

[0034] Among them, when the first clamping plate 23 clamps the crossbeam steel 5, the second roller 25 contacts the side of the crossbeam steel 5. Therefore, when a vertical beam steel 6 is welded and the next vertical beam steel 6 needs to be welded to move the crossbeam steel 5, the first clamping plate 23 does not need to loosen the crossbeam steel 5. The crossbeam steel 5 can be directly pushed to move horizontally, thereby achieving the effect of convenient operation.

[0035] The driving assembly 24 includes a first bracket 241 fixedly connected to the base plate 11, a motor 242 fixedly connected to the first bracket 241, a connecting frame 245 fixedly connected to the first clamping plate 23, a screw 244 fixedly connected to the output shaft of the motor 242, and a supporting seat 243 fixedly connected to the base plate 11, the supporting seat 243 is rotatably connected to the screw 244, and the connecting frame 245 is threadedly connected to the screw 244.

[0036] Among them, when the operation requires the first clamping plate 23 to clamp the crossbeam steel 5, the operation can start the motor 242, and the motor 242 starts its output shaft to drive the screw 244 to rotate. The rotation of the screw 244 drives the connecting frame 245 to move in the direction close to the crossbeam steel 5. The movement of the connecting frame 245 drives the first clamping plate 23 to move, thereby clamping and limiting the crossbeam steel 5.

[0037] The driving unit includes a second bracket 34 fixedly connected to the second slide rail 31 and an electric push rod 35 fixedly connected to the second bracket 34 . The output shaft of the electric push rod 35 is fixedly connected to the second clamping plate 33 .

[0038] When the second clamping plate 33 is needed to clamp the vertical beam steel 6, the operator only needs to start the electric push rod 35, the output shaft of the electric push rod 35 extends, and the extension of the output shaft of the electric push rod 35 drives the second clamping plate 33 to move, thereby the second clamping plate 33 clamps the vertical beam steel 6 to limit the position.

[0039] To summarize, by starting the motor 242, the two first clamps 23 are used to clamp and limit the crossbeam steel 5, so that the crossbeam steel 5 is not easy to move during welding. By placing the vertical beam steel 6 vertically on the crossbeam steel 5, the operator can weld all welding points at one time when welding, and there is no need to adjust the positions of the vertical beam steel 6 and the crossbeam steel 5 in the middle, which makes the welding work fast and convenient. The vertical beam steel 6 is clamped and fixed by the second clamp 33, which can avoid the collapse of the vertical beam steel 6 to cause unsafe factors, and can ensure that the vertical beam steel 6 is not easy to move during welding.

[0040] like Figure 6-Figure 7 The second embodiment of the utility model is shown. Based on the first embodiment, this embodiment further includes a limiting mechanism 4 for preventing the first roller 13 from rotating.

[0041] The limiting mechanism 4 includes a transmission component 41 and a locking component 42; the transmission component 41 includes a sprocket 411 fixedly connected to each of the first rollers 13 and a chain 412 connecting all the sprockets 411 together; the locking component 42 includes a disk 423 fixedly connected to one of the sprockets 411, a plurality of slots 424 uniformly opened on the disk 423, a sleeve 421 fixedly connected to the vertical plate 12 close to the sleeve 423, and a pin 422 slidably connected in the sleeve 421, and the pin 422 is inserted into the slot 424 to prevent the first roller 13 from rotating.

[0042] It is understandable that when welding work is required to prevent the crossbeam steel 5 from moving laterally, the operator can insert the pin 422 into the slot 424. At this time, the disc 423 cannot rotate. The disc 423 cannot rotate and one of the sprockets 411 cannot rotate. Since all the sprockets 411 are connected by the sprocket 411, all the sprockets 411 cannot rotate. The sprocket 411 is fixedly connected to the first roller 13, and the first roller 13 cannot rotate. The crossbeam steel 5 is also not easy to move on the first roller 13. If the first roller 13 needs to rotate, it is only necessary to pull the pin 422 out of the slot 424.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.
