Heavy-duty crane beam assembly jig

Abstract

This utility model relates to a heavy-duty crane beam assembly jig, comprising two first jigs and two second jigs. Both the first and second jigs include a base plate. A support component is fixed to each end of the base plate of the first jig, and two support components are fixed to each end of the base plate of the second jig. Each support component includes two legs, the bottom of which are fixedly connected to the base plate. A support plate is fixed to the top of the two legs. At least one pad is fixed to the middle of the support plate, and a positioning plate is fixed to one end of the support plate near the outer side. The four support components on the second jig can simultaneously support the other end of the end beam segment and the end of the middle beam segment, thus reducing the number of jigs. The use of a common base plate facilitates leveling and reduces the requirements for site flatness. The positioning plates on both sides allow for measurement of the distance between the end beam segment and the middle beam segment and the positioning plate, effectively ensuring precise alignment between the crane beam segments and improving assembly accuracy.

Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a heavy-duty crane beam assembly frame. Background Technology

[0002] Heavy-duty crane beams have large spans and need to be assembled in sections on the construction site. During assembly, due to the unevenness of the construction site and the large spans of the crane beam sections, it is difficult to assemble them on the same horizontal plane.

[0003] Traditional assembly jigs consist of multiple jig units, each independently set up and located at the ends of various sections. These jig units are numerous and heavily influenced by the foundation, requiring individual leveling of each unit, which is time-consuming and labor-intensive. The jig units typically employ simple steel structure combinations, such as those using ordinary steel frames or beams, lacking effective positioning devices and making it difficult to ensure precise alignment between different sections of the crane beam. Utility Model Content

[0004] The main objective of this invention is to provide a heavy-duty crane beam assembly jig, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heavy-duty crane beam assembly jig includes two first jigs and two second jigs, which are arranged side by side and the two second jigs are located between the two first jigs. Both the first jigs and the second jigs include a base plate. A support component is fixed at each end of the base plate of the first jig, and two support components are fixed at each end of the base plate of the second jig. The support components at both ends are arranged symmetrically.

[0007] The support assembly includes two legs, the bottoms of which are fixedly connected to the base plate, and a support plate is fixedly attached to the top of both legs. At least one pad is fixed to the middle of the support plate, and a positioning plate is fixed to one end of the support plate near the outer side.

[0008] Preferably, the base plate is a roadbed box.

[0009] Preferably, the support leg is a vertically arranged first H-beam, and the top of the first H-beam has a steel plate.

[0010] Preferably, the support plate is a second H-beam arranged laterally, and four stiffening plates are fixed on each side of the web of the second H-beam.

[0011] Preferably, when the middle part of the support plate consists of at least two pads, the pads are stacked and their area gradually decreases from bottom to top.

[0012] This utility model provides a heavy-duty crane beam assembly jig, which has the following advantages:

[0013] 1. The four support components on the second jig can simultaneously support the other end of the end beam segment and the end of the middle beam segment, which is equivalent to reducing the number of jigs. The use of a common base plate makes leveling easier and reduces the requirements for site flatness.

[0014] 2. Each section of the crane beam is supported on a pad. On the one hand, by setting different numbers of pads, the height of the end beam sections and the middle beam sections can be adjusted to ensure that they are at the same horizontal level. On the other hand, the distance between the end beam sections and the middle beam sections and the positioning plates can be measured by the positioning plates on both sides. After ensuring that the distance between each beam edge and the positioning plate is consistent, welding is carried out at the segmentation point. This can effectively ensure the precise connection between each section of the crane beam and improve the assembly accuracy. Attached Figure Description

[0024] Example

[0025] Reference Figure 1 A heavy-duty crane beam assembly jig includes two first jigs 1 and two second jigs 2. The two first jigs 1 and two second jigs 2 are arranged side by side, and the two second jigs 2 are located between the two first jigs 1. Both the first jigs 1 and the second jigs 2 include a base plate 3. A support component 4 is fixed at each end of the base plate 3 of the first jigs 1, and two support components 4 are fixed at each end of the base plate 3 of the second jigs 2. The support components 4 at both ends are arranged symmetrically to each other.

[0026] Reference Figure 2-3 The support assembly 4 includes two legs 41, the bottom of the two legs 41 is fixedly connected to the base plate 3, the top of the two legs 41 is fixedly fixed to a support plate 42, at least one pad 43 is fixed in the middle of the support plate 42, and a positioning plate 44 is fixed on one end of the support plate 42 near the outer side.

[0027] Reference Figure 4The heavy-duty crane beam is divided into three sections: two end beam sections 100 and one middle beam section 200. When using the assembly jig of this utility model, two first jigs 1 are arranged at both ends of the crane beam. The two support components 4 on the first jigs 1 are used to support the end of the end beam section 100 that is away from the middle beam section 200. The two second jigs 2 are arranged at the segmentation of the crane beam. The four support components 4 on the second jigs 2 can simultaneously support the other end of the end beam section 100 and the end of the middle beam section 200. This is equivalent to reducing the number of jigs. The use of a common base plate makes leveling easier and reduces the requirements for site flatness.

[0028] The support components 4 at both ends are symmetrically arranged, adopting a point-symmetric support method, and the load-bearing requirements of the base plate are relatively distributed. Specifically, each segment of the crane beam is supported on the pad 43. On the one hand, by setting different numbers of pads 43, the height of the ends of the end beam segment 100 and the middle beam segment 200 can be adjusted to make them at the same horizontal level. On the other hand, the distance between the end beam segment 100 and the middle beam segment 200 and the positioning plate 44 can be measured by the positioning plates 44 on both sides. After ensuring that the distance between each beam edge and the positioning plate 44 is consistent, welding is performed at the segmentation point, which can effectively ensure the precise connection between the segments of the crane beam and improve the assembly accuracy.

[0029] In one specific implementation, the base plate 3 is a roadbed box, which has strong bearing capacity and good stability. In some construction environments with poor ground conditions, such as soft and messy construction sites, the roadbed box can effectively protect the ground and prevent the ground from collapsing or deforming, providing a stable support foundation for the formwork.

[0030] In a specific implementation plan, refer to Figure 2 The support leg 41 is a vertically arranged first H-beam, the first H-beam is of model HW200*200*8*12, and the length is 500mm. The top of the first H-beam has a steel plate 45, the size of which is 10*300*300mm. The support plate 42 can be fixed more stably through the steel plate 45.

[0031] In one specific implementation, the support plate 42 is a second H-beam arranged laterally. The second H-beam is of model HW200*200*8*12 and has a length of 1250mm. Four stiffening plates 46 are fixed on each side of the web of the second H-beam. The stiffening plates 46 have a size of 10*176*96mm. The strength of the support plate 42 can be improved by the stiffening plates 46.

[0032] In one specific implementation, when the middle part of the support plate 42 consists of at least two pads 43, the pads 43 are stacked and their area gradually decreases from bottom to top to form a stepped support structure, which can effectively distribute the load and improve the support stability. The pads 43 can be welded to the support plate 42 according to the site conditions.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
