Description

Technical Field

[0001] The utility model relates to the technical field of H-beam manufacturing equipment, in particular to an H-beam end positioning mechanism. Background Art

[0002] In recent years, with the rapid development of steel structures, the demand for steel structures such as buildings and bridges has continued to increase, and the demand for H-shaped steel types has also increased. One of the requirements is that the ends of H-shaped steel need to be grouped into staggered structures to meet the requirements of connecting multiple H-shaped steels. Among them, the staggered structure refers to Figures 3-4 , the flange and web of H-shaped steel are set at staggered sides.

[0003] In existing technology, because H-beam assembly machines cannot perform staggered positioning on the ends of H-beams, flanges and webs are typically aligned and assembled in pairs. The ends are then manually cut to create staggered H-beam structures. This manual cutting method is labor-intensive, inefficient, and wastes materials, making it unsuitable for modern production. Utility Model Content

[0004] In response to the above problems in the prior art, the present invention provides an H-beam end positioning mechanism, which solves the problem of low production efficiency caused by the use of manual cutting to manufacture the H-beam end staggered structure in the prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] Provided is an H-shaped steel end positioning mechanism, comprising a support platform for supporting and limiting the ends of the H-shaped steel flanges and a clamping member for fixing the H-shaped steel webs; the clamping member comprises two clamping plates both vertically arranged on the support platform, fasteners being provided on the two clamping plates, multiple pairs of positioning holes cooperating with web positioning pins being provided through the sides of the two clamping plates, the ends of the webs being in contact with the web positioning pins and being fixed between the two clamping plates by the fasteners.

[0007] In this solution, the support platform supports and limits the end of the wing plate, and the clamping member can limit the distance between the end of the web plate and the end of the wing plate through the setting of multiple positioning holes and web positioning pins, which can not only meet the staggered pairing of the web plate and the wing plate, but also meet the flush pairing of the web plate and the wing plate. After the clamping member and the support platform fix the web plate and the wing plate, the ends of the web plate and the wing plate can be directly spot welded, and then the connection position of the web plate and the wing plate is welded by an H-shaped steel assembly machine, avoiding subsequent cutting, improving production efficiency, reducing labor, avoiding material waste, and reducing production costs.

[0008] Furthermore, a hydraulic tilting mechanism is installed on the support platform. The clamping member also includes a hinged plate. One end of the hinged plate is fixed between the two clamping plates, and the other end of the hinged plate is hingedly mounted on the support platform. The middle of the hinged plate is hinged to the hydraulic tilting mechanism. The hydraulic tilting mechanism drives the hinged plate to rotate, so that the web and wing plates between the two clamping plates are aligned. The hydraulic tilting mechanism can ensure a tight fit between the web and wing plates during spot welding, eliminating installation gaps.

[0009] Furthermore, the hydraulic tilting mechanism includes a tilting cylinder connected to a hydraulic circuit. The tilting cylinder is hinged to the bottom of the support platform. The hydraulic rod of the tilting cylinder is hinged to one end of the first and second connecting rod assemblies, respectively. The other end of the first connecting rod assembly is hinged to the middle of the hinge plate, and the other end of the second connecting rod assembly is hinged to the support platform. The tilting cylinder drives the hydraulic rod to extend, which drives the first and second connecting rod assemblies to rotate the hinge plate closer to the support platform, thereby driving the hinge plate to tightly contact the webs of the two clamping plates with the wing plates on the support platform.

[0010] Furthermore, the first link assembly includes two first links, symmetrically located on either side of the hydraulic rod and hinge plate. The second link assembly includes two second links, symmetrically located on either side of the hydraulic rod and hinge plate, with the second links located outboard of the first links on the same side. This paired arrangement of first and second links ensures more even force distribution across the hinge plate, extending its service life.

[0011] Furthermore, the length of the second connecting rod is greater than that of the first connecting rod. The length of the second connecting rod is greater than that of the first connecting rod, which makes the flipping action more flexible and can achieve a larger flipping angle in a smaller space.

[0012] Furthermore, both fasteners are set bolts. The sides of the two clamping plates are provided with a plurality of threaded holes arranged in a row. The threaded ends of the two fastening bolts are respectively threaded into the two threaded holes and abut against the sides of the web. The use of fastening bolts, which abut against the sides of the wing plate through the threaded holes, not only facilitates connection but also ensures the stability of the wing plate during turnover and processing, preventing slippage and displacement.

[0013] Furthermore, the support platform is provided with a plurality of positioning grooves arranged in two rows, one on each side of the clamping member. Each positioning groove cooperates with a wing plate positioning pin, which is used to limit the end of the wing plate. At least two wing plate positioning pins are inserted into each of the two rows of positioning grooves. The provision of multiple positioning grooves facilitates limiting the distance between the wing plate ends according to actual needs.

[0014] Furthermore, bases are fixed on both sides of the supporting platform.

[0015] Furthermore, a pad is provided on the support platform, the outer side of the pad extending out of the surface of the support platform and tilted downward. The outer side of the pad is tilted downward to facilitate the placement and removal of the H-shaped steel, improve the convenience of operation, and reduce auxiliary operation time.

[0016] Furthermore, two protrusions are provided on the end surface of the support platform close to the clamping member, the two protrusions are located on both sides of the clamping member, and the upper surface of each protrusion is flush with the upper surface of the support platform. The provision of the protrusions increases the support area for the wing plate.

[0017] The utility model discloses an H-shaped steel end positioning mechanism, which has the following beneficial effects:

[0018] The utility model fixes the wing plate and the web plate respectively by the support platform and the clamping member, and the clamping member can limit the distance between the end of the web plate and the end of the wing plate by the arrangement of multiple positioning holes and the web plate positioning pins, which can not only meet the staggered pairing of the web plate and the wing plate, but also meet the flush pairing of the web plate and the wing plate. After the clamping member and the support platform fix the web plate and the wing plate, the ends of the web plate and the wing plate can be directly spot welded, and then the connection position of the web plate and the wing plate can be welded by an H-shaped steel assembly machine, which avoids subsequent cutting, improves production efficiency, reduces labor, avoids material waste, and reduces production costs.

[0024] The specific implementation methods of the present invention are described below to facilitate understanding of the present invention by those skilled in the art. However, it should be clear that the present invention is not limited to the scope of the specific implementation methods. For those skilled in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the appended claims, these changes are obvious, and all utility model creations using the concept of the present invention are protected.

[0025] refer to Figure 1 and Figure 2 This embodiment provides an H-beam end positioning mechanism, which includes a support platform 1 and a clamping member 2. The support platform 1 is used to support and limit the end of the H-beam flange 5, and the clamping member 2 is used to fix the H-beam web 4.

[0026] Specifically, a base 13 is fixed to each side of the support platform 1. The surface of the support platform 1 is provided with a plurality of positioning grooves distributed in two rows, one on each side of the clamping member 2. Each positioning groove cooperates with a wing plate positioning pin 11, which is used to limit the end of the wing plate 5. At least two wing plate positioning pins 11 are inserted into the two rows of positioning grooves. The provision of multiple positioning grooves facilitates limiting the distance between the ends of the wing plate 5 according to actual needs.

[0027] Two protrusions 14 are provided on the end surface of the support platform 1 near the clamping member 2. The two protrusions 14 are located on both sides of the clamping member 2, and the upper surface of each protrusion 14 is flush with the upper surface of the support platform 1. The provision of the protrusions 14 increases the support area for the wing plate 5.

[0028] The support platform 1 is provided with a pad 12, the outer side of the pad 12 extending out of the surface of the support platform 1 and tilted downward. The outer side of the pad 12 is tilted downward to facilitate the placement and removal of the H-shaped steel, improve the convenience of operation, and reduce the auxiliary operation time.

[0029] Specifically, the clamping member 2 includes two clamping plates 21 both vertically arranged on the supporting platform 1 .

[0030] The two clamping plates 21 are provided with fasteners 23, both of which are fastening bolts. The sides of the two clamping plates 21 are provided with a plurality of threaded holes arranged in a row. The threaded ends of the two fastening bolts are respectively threadedly connected to the two threaded holes and respectively abut against the sides of the web 4. The fasteners 23 are fastening bolts, and are fixed by abutting against the sides of the wing plate 5 through the threaded holes. This not only facilitates connection but also ensures the stability of the wing plate 5 during turnover and processing, preventing slippage and displacement.

[0031] The sides of the two clamping plates 21 are penetrated by multiple pairs of positioning holes 22 that cooperate with the web positioning pins 24. The ends of the web 4 contact the web positioning pins 24 and are fixed between the two clamping plates 21 by fasteners 23.

[0032] In this embodiment, the support platform 1 supports and limits the end of the wing plate 5, and the clamping member 2 can limit the distance between the end of the web 4 and the end of the wing plate 5 through the setting of multiple positioning holes 22 and the web positioning pins 24, which can not only meet the staggered pairing of the web 4 and the wing plate 5, but also meet the flush pairing of the web 4 and the wing plate 5. After the clamping member 2 and the support platform 1 fix the web 4 and the wing plate 5, the ends of the web 4 and the wing plate 5 can be directly spot welded, and then the connection position of the web 4 and the wing plate 5 can be welded by the H-shaped steel assembly machine, avoiding subsequent cutting, improving production efficiency, reducing labor, avoiding material waste, and reducing production costs.

[0033] As a further solution of this embodiment, in order to ensure a tight fit between the web 4 and the wing 5 and eliminate installation gaps, a hydraulic tilting mechanism 3 is provided on the support platform 1. The clamping member 2 further includes a hinged plate 25. One end of the hinged plate 25 is fixed between the two clamping plates 21. The other end of the hinged plate 25 is hingedly mounted on the support platform 1. The middle portion of the hinged plate 25 is hingedly connected to the hydraulic tilting mechanism 3. The hydraulic tilting mechanism 3 drives the hinged plate 25 to rotate, thereby driving the web 4 and the wing 5 between the two clamping plates 21 to fit together.

[0034] Specifically, the hydraulic tilting mechanism 3 includes a tilting cylinder 31 connected to a hydraulic circuit. The tilting cylinder 31 is hinged to the bottom of the support platform 1. The hydraulic rod of the tilting cylinder 31 is hinged to one end of a first connecting rod assembly 32 and a second connecting rod assembly 33, respectively. The other end of the first connecting rod assembly 32 is hinged to the middle of the hinge plate 25, and the other end of the second connecting rod assembly 33 is hinged to the support platform 1. The tilting cylinder 31 extends the hydraulic rod, which in turn drives the first and second connecting rod assemblies 32 and 33, causing the hinge plate 25 to rotate closer to the support platform 1. This causes the hinge plate 25 to drive the webs 4 on the two clamping plates 21 into close contact with the wing plates 5 on the support platform 1.

[0035] In this embodiment, the hydraulic circuit is based on existing technology, and its specific operating principles and connections will not be further described. The first connecting rod assembly 32 includes two first connecting rods, symmetrically located on either side of the hydraulic rod and hinge plate 25. The second connecting rod assembly 33 includes two second connecting rods, symmetrically located on either side of the hydraulic rod and hinge plate 25. The second connecting rods are located outboard of the first connecting rods on the same side and are longer than the first connecting rods. This paired arrangement of the first and second connecting rods ensures more uniform force distribution on the hinge plate 25, extending its service life.

[0036] To sum up, the working principle of this solution is:

[0037] The support platform 1 is installed on one end close to the external roller conveyor. The web positioning pin 24 is inserted into the positioning groove on the support platform 1 according to the installation position of the web 4. One end of the web 4 is placed on the support platform 1 and in positioning contact with the web 4. The other end of the web 4 is placed on the roller conveyor.

[0038] According to the offset position of the wing plate 5 and the web 4, the wing plate locating pin 11 is inserted into the corresponding positioning hole 22 on the clamping plate 21, and then the wing plate 5 is placed vertically on the web 4 and contacts the wing plate locating pin 11, and the wing plate 5 is fixed between the two clamping plates 21 by tightening the bolts.

[0039] The tilt cylinder 31 is activated to extend the hydraulic rod, which in turn drives the first and second connecting rod assemblies 32 and 33, causing the hinge plate 25 to rotate closer to the support platform 1. This allows the hinge plate 25 to bring the web 4 on the two clamping plates 21 into close contact with the wing plates 5 on the support platform 1, allowing spot welding of the ends of the web 4 and wing plates 5. After the spot welding is complete, the tilt cylinder 31 is activated to retract the hydraulic rod, loosening the fastening bolts. The spot-welded H-beam then passes over the roller conveyor and into the welding process for the remaining joints.

[0040] Although the specific embodiments of the utility model are described in detail in conjunction with the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Within the scope described by the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
