Description

Technical Field

[0001] This invention relates to the field of factory construction, specifically to a crane beam. Background Technology

[0002] A crane beam is a beam structure that supports the operation of a bridge crane. The crane beam is equipped with crane rails, and the crane travels back and forth on the crane beam via the crane rails. Currently, crane beams are usually solid web crane beams, that is, they are made of a single piece of steel plate.

[0003] However, during the construction of factory buildings, due to the influence of the layout of the process equipment below, steel columns cannot be installed in some locations, such as heating furnaces and cooling beds. Therefore, the span of the crane beams in these areas will be very large, some even reaching 60m. If traditional solid web crane beams are used, the manufacturing, transportation and installation will become difficult due to their excessive length and weight (a single 60m long crane beam weighs about 120t). Therefore, there is an urgent need for a crane beam with a simple structure that is easy to manufacture, transport and install. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a crane beam to solve the problems of difficult manufacturing, transportation and installation, as well as the problem of reduced usable space in the factory, when traditional solid web crane beams are applied to large-span factory buildings.

[0005] To achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0007] Both ends of the longitudinal bracket truss are set on the factory building columns, and the upper part of the longitudinal bracket truss is used to connect with the roof truss.

[0008] Multiple cantilever brackets are installed at the lower part of the longitudinal bracket truss along the length of the longitudinal bracket truss;

[0017] The upper end of the second diagonal web member is connected to the upper end of the second vertical web member, and the lower end is connected to the lower end of the other first diagonal web member.

[0018] Both the lower ends of the first and second vertical braces are equipped with cantilever brackets.

[0019] Preferably, the multiple first vertical web members are evenly arranged along the axial direction of the fixed member.

[0020] Preferably, the first vertical web member and the second vertical web member are the same;

[0026] Preferably, the horizontal truss includes: a first horizontal bar, a second horizontal bar, and a plurality of connecting bars;

[0029] Preferably, the multiple connecting rods are evenly arranged along the length direction of the first horizontal rod.

[0030] Preferably, the crane track beam includes: multiple crane track beams;

[0031] The crane track beam is set on top of two adjacent cantilever brackets.

Detailed Implementation

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] In this application, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0040] This invention provides a crane beam, see [link to relevant documentation]. Figure 1 and combined Figure 2 , Figure 1 This is a structural schematic diagram of a crane beam, which includes: a longitudinal support truss 1, a horizontal truss 2, a crane track beam 3, and multiple cantilever brackets 4;

[0041] Both ends of the longitudinal bracket truss 1 are set on the factory building columns, and the upper part of the longitudinal bracket truss 1 is used to connect with the roof truss.

[0042] Multiple cantilever brackets 4 are arranged along the length of the longitudinal bracket truss 1 at the lower part of the longitudinal bracket truss 1;

[0043] The horizontal truss 2 is installed under multiple cantilever brackets 4;

[0044] The tops of multiple cantilever brackets 4 are used to place the crane track beam 3.

[0045] It should be noted that the horizontal truss 2 is located at the bottom of multiple cantilever brackets 4, and its main function is to connect the multiple cantilever brackets 4 together.

[0046] It should also be noted that by setting the longitudinal bracket truss 1, in terms of vertical load, the moving load of the crane is transferred to the cantilever bracket 4 through the crane track beam 3, and then to the lower chord of the longitudinal bracket truss 1, while the roof load is transferred to the upper chord of the longitudinal bracket truss 1 through the roof truss. The vertical load is borne and resisted by the longitudinal bracket truss 1.

[0047] Because the longitudinal bracket truss 1 is very tall, it has high vertical stiffness and very small vertical deformation.

[0048] Regarding lateral horizontal loads, the moving load of the crane is transmitted to the cantilever bracket 4 through the crane track beam 3, and then resisted by the horizontal truss 2.

[0049] It is worth noting that the cross-sectional height of the horizontal truss 2 in this application is the same as the distance between the column legs of the factory building column.

[0050] In this embodiment of the invention, both ends of the longitudinal bracket truss 1 are positioned on the factory building columns, and the upper part of the longitudinal bracket truss 1 is used to connect with the roof truss. Multiple cantilever brackets 4 are arranged along the length of the longitudinal bracket truss 1 at the lower part of the longitudinal bracket truss 1. A horizontal truss 2 is arranged below the multiple cantilever brackets 4, and the top of the multiple cantilever brackets 4 is used to place the crane rail beam 3. With the crane beam disclosed above, because this application consists of the longitudinal bracket truss 1, the horizontal truss 2, the crane rail beam 3, and the multiple cantilever brackets 4, the crane beam of this application, compared to the traditional solid-web crane beam, not only has a simpler structure and is easier to manufacture, transport, and install, but also leverages the vertical bending resistance advantage of the longitudinal bracket truss 1, reducing vertical deformation, increasing structural safety and comfort, and reducing overall weight, thus achieving the goal of saving materials.

[0051] Specifically, the longitudinal bracket truss 1 includes: a fixed rod 11, multiple first vertical web members 12, multiple second vertical web members 13, and multiple diagonal web member groups;

[0052] The upper ends of the multiple first vertical web members 12 are all connected to the fixed rod 11 and are perpendicular to the fixed rod 11;

[0053] The diagonal web members and the second vertical web members 13 are both located between two adjacent first vertical web members 12;

[0054] The upper end of the second vertical web member 13 is connected to the fixed member 11 and is perpendicular to the fixed member 11;

[0055] The diagonal web member assembly includes a first diagonal web member 141 and a second diagonal web member 142;

[0056] The lower end of the first diagonal web member 141 is connected to the lower end of the first vertical web member 12, and the upper end is connected to the upper end of the second vertical web member 13.

[0057] The upper end of the second oblique web member 142 is connected to the upper end of the second vertical web member 13, and the lower end is connected to the lower end of the other first oblique web member 141.

[0058] Both the lower ends of the first vertical brace 12 and the second vertical brace 13 are provided with cantilever brackets 4.

[0059] It should be noted that the longitudinal bracket truss 1 is configured as a fixed rod 11, multiple first vertical web members 12, multiple second vertical web members 13, and multiple diagonal web member groups. The upper ends of the multiple first vertical web members 12 are all connected to the fixed rod 11 and are perpendicular to the fixed rod 11. The diagonal web member groups and second vertical web members 13 are all arranged between two adjacent first vertical web members 13. The upper ends of the second vertical web members 13 are connected to the fixed rod 11 and are perpendicular to the fixed rod 11. The diagonal web member groups include first diagonal web members 141 and second diagonal web members 142. The lower end of the first diagonal web member 141 is connected to the lower end of the first vertical web member 12, and the upper end is connected to... The upper end of the second vertical web member 13 is connected, the upper end of the second diagonal web member 142 is connected to the upper end of the second vertical web member 13, and the lower end is connected to the lower end of another first diagonal web member 141. The lower ends of the first vertical web member 12 and the second vertical web member 13 are both provided with cantilever brackets 4. Thus, the fixed rod 11, multiple first vertical web members 12, multiple second vertical web members 13 and multiple diagonal web member groups can form multiple stable triangular structures. Thus, the moving load of the crane is transmitted to the cantilever brackets 4 through the crane track beam 3, and then to the lower chord of the longitudinal bracket truss 1, so that the longitudinal bracket truss 1 is not easily deformed in the vertical direction.

[0060] Preferably, the fixing rod 11, multiple first vertical web members 12, multiple second vertical web members 13, and multiple diagonal web members are assembled by bolt connection.

[0061] It should be noted that the fixing rod 11, multiple first vertical web members 12, multiple second vertical web members 13, and multiple diagonal web member groups are assembled by bolt connection, and the number of multiple first vertical web members 12, multiple second vertical web members 13, and multiple diagonal web member groups can be set according to the requirements.

[0062] Specifically, multiple first vertical web members 12 are evenly arranged along the axial direction of the fixed member 11.

[0063] It should be noted that by evenly arranging multiple first vertical web members 12 along the axial direction of the fixed rod 11, the longitudinal bracket truss 1 is subjected to more uniform force, thereby improving the overall rigidity of the longitudinal bracket truss 1.

[0064] Furthermore, the first vertical web member 12 and the second vertical web member 13 are the same;

[0065] The first vertical web member 12 is an H-beam or a rectangular steel.

[0066] It should be noted that the first vertical web member 12 and the second vertical web member 13 can be H-beams of the same length or rectangular steel of the same length. Those skilled in the art can choose according to their needs.

[0067] Furthermore, the first diagonal web member 141 and the second diagonal web member 142 are the same;

[0068] The first diagonal web member 141 is an H-beam or a rectangular steel.

[0069] It should be noted that the first diagonal web member 141 and the second diagonal web member 142 can be H-beams of the same length or rectangular steel of the same length. Those skilled in the art can choose according to their needs.

[0070] Specifically, the lower ends of the first vertical brace 12 and the second vertical brace 13 are both connected to the middle of the cantilevered corbel 4;

[0071] The tops of both ends of the cantilever bracket 4 are used to place the crane track beam 3.

[0072] It should be noted that since the crane rail beam 3 is placed on top of the cantilever bracket 4, and the cantilever bracket 4 is connected to the lower end of the first vertical brace 12 or the second vertical brace 13, in order to ensure that the forces on both ends of the cantilever bracket 4 are even, the lower ends of the first vertical brace 12 and the second vertical brace 13 are connected to the middle of the cantilever bracket 4. Thus, the top of both ends of the cantilever bracket 4 can be used to place the crane rail beam 3. This ensures that the crane rail beam 3 set at both ends of the cantilever bracket 4 can be stressed at the same time, effectively avoiding the separation of the crane rail beam 3 from the cantilever bracket 4 due to uneven forces on both ends of the cantilever bracket 4.

[0073] Specifically, the horizontal truss 2 includes: a first horizontal bar, a second horizontal bar, and multiple connecting bars;

[0074] The first horizontal bar and the second horizontal bar are set parallel to each other;

[0075] The two ends of the connecting rod are connected to the first horizontal bar and the second horizontal bar, respectively.

[0076] It should be noted that the horizontal truss 2 is configured as a first horizontal bar, a second horizontal bar, and multiple connecting bars. The first horizontal bar and the second horizontal bar are set parallel to each other, and the two ends of the connecting bars are connected to the first horizontal bar and the second horizontal bar respectively. Multiple cantilever brackets 4 are connected through the horizontal truss 2, so that the horizontal truss 2, the longitudinal bracket truss 1, and the multiple cantilever brackets 4 can form multiple stable triangular structures, effectively improving the stiffness of the crane beam.

[0077] Specifically, multiple connecting rods are evenly arranged along the length of the first horizontal rod.

[0078] It should be noted that evenly arranging multiple connecting rods along the length of the first horizontal rod can further improve the rigidity of the horizontal truss 2, making the horizontal truss 2 less prone to deformation.

[0079] Furthermore, the crane track beam 3 includes: multiple crane sub-track beams;

[0080] The crane track beam is set on top of two adjacent cantilever brackets.

[0081] It should be noted that the crane track beam 3 is set as multiple crane sub-track beams, and the crane sub-track beams are set on the top of two adjacent cantilever brackets. Thus, the staff can set the number of multiple crane track beams and the length of a single crane track beam according to the span length.

[0082] Specifically, the crane track beam is fixed to the cantilever bracket 4 by bolts.

[0083] It should be noted that fixing the crane rail beam to the cantilever bracket 4 with bolts can effectively improve the efficiency of workers installing the crane rail beam 3.

[0084] The crane beam provided by this invention is suitable for ultra-large span factory buildings with a span range of 30m to 100m.

[0085] The present invention has the following advantages:

[0086] 1. By utilizing the space above the crane rail elevation to set up a longitudinal bracket truss, the height of the components below the crane rail elevation is reduced, which greatly improves the space height under the crane rail at the column removal location in the factory building, providing more space convenience for equipment operation, maintenance and replacement.

[0087] 2. By placing the crane track beam on the cantilevered brackets of the vertical web members (the first and second vertical web members), the span of the crane beam is reduced from the original super-long distance to the distance between the vertical web members (i.e., the distance between the first and second vertical web members). The height and weight of the component section are greatly reduced, which reduces the design difficulty, the processing and manufacturing difficulty, the transportation difficulty, and the on-site installation difficulty, and greatly saves costs and construction time.

[0088] 3. Compared to a solid-web beam with the same cross-sectional height, the solid-web beam is significantly heavier and has less resistance to vertical deformation than the crane beam described in this application. Therefore, using a longitudinal support truss reduces steel consumption while improving resistance to vertical deformation, resulting in lower costs and increased comfort.

[0089] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
