Description

Technical Field

[0001] The present invention relates to the field of flame cutting equipment for construction steel beams, and particularly to a steel beam cutting device for steel structure building construction. Background Technique

[0002] A steel structure building is a building with a load-bearing structure composed of construction steel. Usually, components such as beams, columns, and trusses made of section steel and steel plates form the load-bearing structure. It forms the entire building together with enclosure structures such as the roof, floor, and wall.

[0003] Steel beams are used in steel structure buildings. Sometimes when in use, it is necessary to shorten the length of the steel beam, and it is necessary to cut off the entire end of the steel beam. However, because the structure of the steel beam is generally I-shaped, the general method for its overall cutting is for workers to hold a cutting torch and rotate the cutting torch to cut off the end completely. This method is relatively rough and requires a high level of proficiency for workers. Otherwise, it is easy to cut off-center, resulting in an uneven cut surface. And sometimes due to holding the cutting torch, the distance from the steel beam is different, and finally the quality of the cut surface is also different, and it is also time-consuming and laborious to polish it later.

Specific embodiments

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1 to 8 , the present invention provides a technical solution: a steel beam cutting device for steel structure building construction, including a support 1, a vertical frame 2, a turntable structure 3 and a cutting structure 4. The vertical frame 2 is fixedly installed on the support 1, the turntable structure 3 is installed in the vertical frame 2, and the cutting structure 4 is installed on the vertical frame 2.

[0018] In this embodiment, the turntable structure 3 includes a turntable 31, a clamping assembly 32 and a limiting structure 33. The turntable 31 is rotatably installed in the stand 2 and can rotate freely. The clamping assembly 32 is installed on the turntable 31, and the limiting structure 33 is fixedly installed on the turntable 31. When the turntable 31 rotates, it can drive the clamping assembly 32 and the limiting structure 33 to rotate, so that the rotation of the turntable 31 can act on the steel beam and the gas cutting gun 41 at the same time, forming a linkage between the movements of the two.

[0019] In this embodiment, the cutting structure 4 includes a gas cutting gun 41 and a position adjustment structure 42. The gas cutting gun 41 is fixedly mounted on the position adjustment structure 42, and the position adjustment structure 42 is fixedly mounted on the stand 2. The position adjustment structure 42 drives the gas cutting gun 41 to move up and down by cooperating with the turntable 31 and the limiting structure 33.

[0020] In this embodiment, a bearing platform 11 is provided on the bracket 1 , and a buffer platform 12 is provided at the front end of the bearing platform 11 . The buffer platform 12 is used to receive the steel beam that falls after cutting.

[0021] In this embodiment, a through hole 311 is provided at the center position of the turntable 31, and a guide track 34 is provided on the turntable 31. The guide track 34 is divided into track one 341, track two 342 and track three 343. The track one 341 and track three 343 are straight lines. The track one 341, track two 342 and track three 343 have a smooth transition at the interface. The straight track one 341 and track three 343 will make the gas cutting gun 41 move from high to low and then to high when the turntable 31 rotates. In this way, when the upper flange plate of the steel beam rotates, it can better match the shape of higher sides and lower middle, keeping the position of the gas cutting gun 41 to the steel beam flange plate basically unchanged, and the inwardly recessed track two 342 can fit the web in the middle of the steel beam, keeping the position of the gas cutting gun 41 to the web basically unchanged.

[0022] In this embodiment, a gear ring 312 is provided on the turntable 31, and a chuck 313 is provided at the root of the turntable 31. The gear ring 312 is meshed with a gear 314, and the gear 314 is fixedly mounted on a motor 315. The motor 315 is fixedly mounted on the top of the stand 2. A cover box 316 is provided on the outer side of the motor 315. The chuck 313 is rotatably clamped in the stand 2, and the gear 314 and the gear ring 312 are driven to rotate by the motor 315, and finally the turntable 31 is driven to rotate, and the chuck 313 provides a limiting function.

[0023] In this embodiment, there are two sets of symmetrically arranged clamping assemblies 32. The clamping assembly 32 includes a hydraulic cylinder 321, a connecting plate 322, and clamping pliers 323. The hydraulic cylinder 321 is fixedly installed on the turntable 31 through a bracket. The connecting plate 322 is fixedly installed on the output shaft of the hydraulic cylinder 321. The clamping pliers 323 are fixedly installed at both ends of the connecting plate 322 and are used to clamp the edge of the flange plate of the steel beam. By clamping the edge of the flange plate of the steel beam with the clamping pliers 323 and cooperating with the hydraulic cylinder 321, the steel beam can be fixed to ensure the quality of the cut surface.

[0024] In this embodiment, the limiting structure 33 includes guiding pieces 331 respectively arranged below the first track 341 and the third track 343. The guiding pieces 331 are fixedly installed on the turntable 31 through vertical plates 332 at the lower part. The end of the guiding piece 331 is provided with a guiding surface, and the guiding surface can exert a force on the clamping plate 422 to push the clamping plate 422 and the gas cutting torch 41 to move up and down.

[0025] In this embodiment, the position adjusting structure 42 includes a fixing plate 421, a clamping plate 422, and a limiting screw 423. The fixing plate 422 is fixedly installed on the vertical frame 2. A guiding column 424 is arranged below the fixing plate. A spring 425 is sleeved on the guiding column 424. The lower end of the spring 425 abuts against the clamping plate 422. The top of the limiting screw 423 is threadedly connected to the fixing plate 421, and the head of the limiting screw 423 is located below the clamping plate 422. Through the action of the spring 425, the clamping plate 422 can clamp the gas cutting torch 41 and stably move in the guiding track 34.

[0026] In this embodiment, the clamping plate 422 includes a clamping section 4221, a cylindrical section 4222, a reinforcing section 4223, and a wear-resistant section 4224. One end of the clamping section 4221 is fixedly connected to the gas cutting torch 41, and the other end is fixedly connected to the cylindrical section 4222. The wear-resistant section 4224 can contact the outer side surface of the guiding piece 331 when the guiding piece 331 rotates. The cylindrical section 4222 is located in the guiding track 34. The clamping section 4221 is used to clamp the gas cutting torch 41. The cylindrical section 4222 can move better in the guiding track 34, and the wear-resistant section 4224 contacts the guiding piece 331.

[0027] Working principle: First, fix the steel beam through the clamping assembly 32. In the initial state, the included angle of the top flange plate of the steel beam is directly above. At this time, the gas cutting torch 41 is located at the outermost side of the first track 341. Then, start the turntable 31 and the gas cutting torch 41. As the turntable 31 rotates, the steel beam rotates. At the same time, the first track 341 guides the up and down movement of the gas cutting torch 41. When the upper flange plate of the steel beam rotates to a horizontal state, the gas cutting torch 41 moves to the middle position of the first track 341. At this time, the gas cutting torch 41 is at the lowest position of the first track 341, and the distance between the gas cutting torch 41 and the upper flange plate of the steel beam can be maintained, thereby ensuring the cutting surface quality during flame gas cutting. As it rotates, while the edge of the upper flange plate rotates and rises, the gas cutting torch 41 gradually rises, and then slides into the second track 342 under the action of the spring 425. At this time, the web of the steel beam is located below the gas cutting torch 41, and the web is cut. Then, the clamping plate 422 will contact the guide piece during the continuous rotation of the turntable 31 and be lifted under the action of the guide piece 331 and re-enter the third track 343 to gas cut the lower flange plate that rotates to the upper side until the steel beam is completely gas cut open.

Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
