Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting machine supporting components, in particular to a cantilever steel beam structure. Background Art

[0002] With the continuous development of laser cutting machine functional technology, H-beam special machines in the steel structure industry have become a new growth point for laser business. At present, mainstream laser companies have begun to enter this field. At the same time, they need to quickly launch such products and get rid of low-price competition. The conventional H-beam beam structure is a gantry type, and the loading process is cumbersome. The beam must be opened out of the stroke before loading from the side. The stroke is large and takes up space. The cantilever steel beam structure can be directly loaded from the side without considering the position of the beam, but the cantilever steel beam has only one-side support, which requires higher structural rigidity. Therefore, it is necessary to develop a new cantilever steel beam mechanism with stable structure, lightweight, simple structure, convenient manufacturing, and strong anti-deformation ability, so as to ensure the stability and reliability of the beam during use as much as possible and protect the body from damage. At present, most domestic companies find it difficult to make breakthroughs in this regard. This structure will greatly enhance the competitiveness of H-beam special machine products. Utility Model Content

[0003] In order to solve the technical problem of complicated gantry structure commonly found in the production of H-beam special machines existing in the background technology, the purpose of the utility model is to provide a cantilever steel beam structure that can solve the above problem.

[0004] The technical solution for achieving the purpose of the utility model is: a cantilever steel beam structure, including a support beam and a cross beam, one end of the cross beam is installed on the top of the support beam; the support beam and the cross beam are respectively spliced ​​into a support beam frame and a cross beam frame by multiple steel pipes, and sealing plates are installed on the support beam frame and the cross beam frame; the cantilever steel beam structure completes single-sided support loading through the cooperation of the support beam and the cross beam.

[0005] In this technical solution, the support beam is used as a support, and one end of the beam is installed on the support beam to assemble into a single-sided support mechanism. Different from the gantry double-support beam structure, the workpiece is restricted by the support beams on both sides and cannot move freely. The single-sided support structure is more flexible. The workpiece can be flexibly moved on one side. The cantilever beam can be stopped at any position for loading, while the gantry beam needs to be moved outside the loading stroke to load. The cantilever beam is more convenient and saves space. In addition, the present structure adopts a skeleton structure made of multiple steel pipes, and then the sealing plate is installed. The structure is simple and easy to assemble. The overall structure is lighter and uses less consumables, which effectively reduces the cost of the enterprise.

[0006] Furthermore, inclined steel pipes are installed on the crossbeam frame, especially triangular inclined steel pipes, which can improve the structural properties and bearing capacity of the crossbeam frame.

[0007] Furthermore, the side of the crossbeam frame is also provided with ribs, and the ribs are evenly arranged along the side of the crossbeam frame. Since the crossbeam is supported by only one supporting beam during loading, its structure needs to bear a greater force, so adding ribs can improve its structural and load-bearing effect.

[0008] Furthermore, the rib plate has a thickness of 2 mm to 10 mm, that is, the rib plate within this range can ensure the structural integrity of the beam without increasing the weight of the beam itself due to excessive use of material, and can also reduce costs.

[0009] Furthermore, a diagonal brace plate is installed between the support beam and the cross beam. Since the cross beam is supported by only one support beam, adding a diagonal brace plate between the two can effectively improve the supporting effect of the support beam, which is quite common in reality and will not be elaborated herein.

[0010] Furthermore, the support beam and the cross beam are vertically arranged, and the angle between the diagonal support plate and the support beam is between 60° and 70°. After comparative analysis, in the structure of the present device, the diagonal support plate is arranged at this angle to maximize the diagonal support effect, thereby improving the supporting effect of the support beam on the cross beam.

[0011] Furthermore, a plurality of mounting holes are provided on one side of the beam, which facilitates the connection and fixation of the cantilever steel beam with other components. The cantilever steel beam structure in this solution needs to be installed in combination with other components in the later stage. After the mounting holes are set in advance, there is no need to drill holes separately in the later stage, which facilitates the connection and installation with other components and improves the installation efficiency. Guide rails can also be provided to facilitate the sliding with other components.

[0012] Furthermore, the cross-sectional size of the steel pipe is 30mm*30mm*2.5mm-60mm*60mm*5mm

[0013] Furthermore, the sealing plate is a steel plate, which has high rigidity and can ensure the overall strength requirement for loading materials in the production of cantilever steel beams.

[0014] Furthermore, the support beam frame and the cross beam frame are welded by a plurality of the steel pipes, and the sealing plate is welded to the support beam frame and the cross beam frame. Compared with fixing methods such as bundling, the welding connection method has a better fixing effect and can ensure the connection effect of the overall skeleton structure.

[0015] Furthermore, structures such as universal wheels or slide rails may be provided under the support beam to facilitate its movement.

[0016] By adopting the above technical solution, the utility model has the following beneficial effects:

[0017] (1) One end of the crossbeam is installed on the support beam to form a single-side support structure, which is convenient for flexible loading in the production of H-beam special machines and overcomes the disadvantages of the gantry structure;

[0018] (2) The integral cantilever steel beam frame is welded from multiple steel pipes and sealed on the surface with steel plates. The overall structure is relatively simple, easy to overlap, and the overall weight is lighter and the cost is lower;

[0019] (3) Connect a diagonal brace plate between the support beam and the cross beam to improve the support effect of the support beam on the cross beam. Even if there is only one-side support, its structural performance can meet the requirements of loading;

[0020] (4) Add ribs to the beam to improve the structural integrity and rigidity of the beam;

[0021] (5) Adding a mounting hole on one side of the beam can facilitate the subsequent connection and installation with other components and improve installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

In this technical solution, the support beam 1 is used as a support, and one end of the beam 2 is installed on the support beam 1 to assemble into a single-sided support mechanism. Different from the structure of the gantry double support beam 1, the single-sided support structure is more flexible, and the production raw materials can be flexibly supplied on one side. The cantilever beam can be stopped at any position for loading, while the gantry beam needs to be moved outside the loading stroke to load. The cantilever beam is more convenient and reduces space. In this structure, a plurality of steel pipes 3 are spliced ​​into a skeleton structure, and then a sealing plate 6 is installed. The structure is simple and easy to assemble. The overall structure is lighter and uses less consumables, which effectively reduces the cost of the enterprise.

[0030] Preferably, the cross-sectional size of the steel pipe 3 is 30mm*30mm*2.5mm-60mm*60mm*5mm

[0031] Preferably, the sealing plate 6 is a steel plate having high rigidity, which ensures the overall strength requirement for loading materials in the production of cantilever steel beams.

[0032] Preferably, the support beam frame 4 and the cross beam frame 5 are welded by a plurality of the steel pipes 3, and the sealing plate 6 is welded to the support beam frame 4 and the cross beam frame 5. Compared with fixing methods such as bundling, the welding connection method has a better fixing effect and can ensure the connection effect of the overall skeleton structure.

[0033] like Figure 1 As shown, a plurality of mounting holes 10 are provided on one side of the crossbeam 2, which facilitates the connection and fixation of the cantilever steel crossbeam with other components. The cantilever steel crossbeam structure in this scheme needs to be assembled and installed with other components in the later stage. After the mounting holes 10 are set in advance, there is no need to drill holes separately in the later stage, which facilitates the connection and installation with other components and improves the installation efficiency. A guide rail 12 can also be provided to facilitate the sliding with other components.

[0036] Preferably, the side of the crossbeam frame 5 is also provided with a rib plate 8, and the rib plate 8 is evenly arranged along the side of the crossbeam frame 5. Since the crossbeam 2 is supported by only one supporting beam 1 during loading, its structure needs to bear a greater force, so adding the rib plate 8 can improve its structural and load-bearing effect. The thickness of the rib plate 8 is 2mm-10mm, that is, the rib plate 8 in this range can ensure the structural property of the crossbeam 2, and will not increase the weight of the crossbeam 2 itself due to excessive material, and reduce costs.

[0037] Preferably, a diagonal brace plate 9 is installed between the support beam 1 and the cross beam 2. Since the cross beam 2 is supported by only one support beam 1, adding a diagonal brace plate 9 between the two can effectively improve the support effect of the support beam 1. This is more common in reality and will not be described in detail. The support beam 1 and the cross beam 2 are vertically arranged, and the angle between the diagonal brace plate 9 and the support beam 1 is between 60° and 70°.
