Description

Technical Field

[0001] This utility model relates to the field of factory building technology, specifically to a detachable steel crane beam suitable for concrete structures. Background Technology

[0002] Crane beams, as key components supporting the operation of lifting and transportation equipment, are widely used in various building structural systems in construction projects such as industrial plants, warehousing facilities, and bridges. Traditional crane beams mostly adopt reinforced concrete structures or integral welded steel structures, which are directly and permanently connected to the main structure. Although they have good load-bearing capacity and durability, they have certain limitations in practical applications. Especially in some temporary projects, renovation projects, or construction sites with limited construction periods, traditional fixed crane beams are difficult to install and dismantle due to their complexity, making it difficult to meet the needs of flexible layout and rapid assembly and disassembly.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a detachable steel crane beam suitable for concrete structures. This solves the technical problem in some temporary projects, renovation projects, or construction sites with limited construction periods where traditional fixed crane beams are difficult to install and dismantle, thus failing to meet the needs for flexible arrangement and rapid assembly and disassembly.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: A detachable steel crane beam suitable for concrete structures is provided, comprising: a mounting plate mounted on a concrete column; a support assembly having a first support portion and a second support portion, the first and second support portions being movably disposed on the mounting plate in a vertical direction, the first support portion being located at the top of the second support portion, the second support portion extending in a vertical direction, the first support portion extending in a predetermined direction, and the extension direction of the first support portion being perpendicular to the extension direction of the second support portion; a bridge crane assembly disposed on the support assembly; and a connecting assembly movably disposed on the mounting plate in a vertical direction, the first and second support portions being connected to the mounting plate via the connecting assembly.

[0006] Furthermore, the connecting component includes: a dovetail block, a mounting plate having a mounting hole extending vertically, the dovetail block being movably disposed within the mounting hole along the extension direction of the mounting hole; the side of the dovetail block away from the concrete column is connected to the second support.

[0007] Furthermore, the connecting component also includes: a shaped block, which is movably mounted on the mounting plate in a vertical direction, the shaped block and the dovetail block are spaced apart, and the top of the shaped block is connected to the first support portion.

[0008] Furthermore, the support assembly includes: a stabilizing plate, which is movably mounted on the mounting plate in a vertical direction; the side of the stabilizing plate near the concrete column is connected to a dovetail block for insertion onto the mounting plate via the dovetail block; a support plate, located on top of the mounting plate and the stabilizing plate, which is movably mounted on the mounting plate in a vertical direction, and the bottom of the support plate is connected to a shaped block for insertion onto the mounting plate via the shaped block; wherein the support plate forms a first support portion; and the stabilizing plate forms a second support portion.

[0009] Furthermore, the bridge crane assembly includes: a crossbeam extending along the width of the concrete column, the crossbeam being connected to at least a portion of the support assembly by fasteners; the crossbeam extending in a predetermined direction; a slide rail extending along the extension direction of the crossbeam and mounted on the crossbeam; and a bridge crane movably mounted on the slide rail along the extension direction of the slide rail.

[0010] Beneficial effects:

[0011] 1. The support components form a spatial force-bearing system through the vertical distribution design of the first and second support parts. The dovetail blocks and irregular blocks of the connecting components realize detachable vertical connections. The mounting plate and the embedded parts of the concrete column cooperate to form the foundation bearing surface. The bridge crane components, through the modular assembly of the crossbeam and the slide rail, jointly construct a hoisting system that can be quickly assembled and disassembled. This structure breaks through the traditional welding / casting fixing mode and realizes the non-destructive installation and reuse of the crane beam on the concrete column.

[0012] 2. The wedge-shaped mating surface of the dovetail block and the mounting hole creates a self-locking effect. When the second support is subjected to a vertical load, the inclined surface of the dovetail block and the inner wall of the mounting hole form a contact stress reinforcement zone. This design ensures the connection strength while allowing the second support to be quickly disassembled by vertically lifting the dovetail block, avoiding the wrench operation space limitation required by traditional bolt connections and significantly improving the disassembly and assembly efficiency in confined spaces.

[0013] 3. The asymmetrical contour of the irregular block and the guide groove of the mounting plate form an anti-lateral displacement constraint. The hinged design of its top and the first support can compensate for the unevenness error of the mounting surface. The spaced arrangement of the irregular block and the dovetail block forms a double locking mechanism. Under the action of horizontal load, the protrusion of the irregular block contacts the mounting plate to generate an anti-overturning moment, which effectively improves the stability of the crane beam under dynamic load.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] According to an embodiment of this utility model, a detachable steel crane beam suitable for concrete structures is provided. Please refer to [link / reference]. Figures 1 to 2 The system includes: a mounting plate 1, which is mounted on a concrete column; a support assembly having a first support portion and a second support portion, which are movably mounted on the mounting plate 1 in a vertical direction, with the first support portion located on top of the second support portion and the second support portion extending in a vertical direction, while the first support portion extends in a preset direction and the extension direction of the first support portion is perpendicular to the extension direction of the second support portion; a bridge crane assembly mounted on the support assembly; and a connecting assembly movably mounted on the mounting plate 1 in a vertical direction, with the first support portion and the second support portion connected to the mounting plate 1 via the connecting assembly.

[0020] By adopting the above technical solution, the support components form a spatial force-bearing system through the vertical distribution design of the first and second support parts. The dovetail block 2 and the irregular block 4 of the connecting components achieve detachable vertical connections. The mounting plate 1 and the embedded parts of the concrete column cooperate to form the foundation bearing surface. The bridge crane components, through the modular assembly of the crossbeam 7 and the slide rail, jointly construct a hoisting system that can be quickly assembled and disassembled. This structure breaks through the traditional welding / casting fixing mode, realizing the non-destructive installation and reuse of the crane beam on the concrete column.

[0021] Furthermore, multiple concrete columns are provided, with two concrete columns forming a group, and the mounting plates 1 on the two concrete columns are arranged opposite each other, and the bridge crane assembly is movably arranged between the two concrete columns.

[0022] Please refer to Figure 2The connecting component includes: a dovetail block 2; a mounting plate 1 has a mounting hole 3 extending in a vertical direction; the dovetail block 2 is movably disposed in the mounting hole 3 along the extension direction of the mounting hole 3; the side of the dovetail block 2 away from the concrete column is connected to the second support part.

[0023] By adopting the above technical solution, the wedge-shaped mating surface of the dovetail block 2 and the mounting hole 3 generates a self-locking effect. When the second support part is subjected to vertical load, the inclined surface of the dovetail block 2 and the inner wall of the mounting hole 3 form a contact stress reinforcement zone. This design ensures the connection strength while allowing the second support part to be quickly disassembled by vertically lifting the dovetail block 2, avoiding the wrench operation space limitation required by traditional bolt connection, and significantly improving the disassembly and assembly efficiency in a narrow space.

[0024] Please refer to Figure 2 The connecting component also includes: a shaped block 4, which is movably mounted on the mounting plate 1 in a vertical direction. The shaped block 4 is spaced apart from the dovetail block 2, and the top of the shaped block 4 is connected to the first support.

[0025] By adopting the above technical solution, the asymmetrical contour of the irregular block 4 and the guide groove of the mounting plate 1 form an anti-lateral displacement constraint, and the hinged design of its top and the first support can compensate for the unevenness error of the mounting surface. The spaced arrangement of the irregular block 4 and the dovetail block 2 forms a double locking mechanism. Under the action of horizontal load, the protrusion of the irregular block 4 contacts the mounting plate 1 to generate an anti-overturning moment, effectively improving the stability of the crane beam under dynamic load.

[0026] Furthermore, the transverse cross-sectional shape of the irregular block 4 can be a triangle, a quadrilateral, a pentagon, etc.

[0027] Please refer to Figure 1 and Figure 2 The support assembly includes: a stabilizing plate 5, which is movably mounted on the mounting plate 1 in a vertical direction; the side of the stabilizing plate 5 closest to the concrete column is connected to a dovetail block 2 so as to be inserted into the mounting plate 1 via the dovetail block 2; a support plate 6, which is located on top of the mounting plate 1 and the stabilizing plate 5, and is movably mounted on the mounting plate 1 in a vertical direction; the bottom of the support plate 6 is connected to a shaped block 4 so as to be inserted into the mounting plate 1 via the shaped block 4; wherein the support plate 6 forms a first support part; and the stabilizing plate 5 forms a second support part.

[0028] By adopting the above technical solution, the split structure of the stabilizing plate 5 and the supporting plate 6 achieves decoupling of the load-bearing function: the stabilizing plate 5 bears the main vertical load through the dovetail block 2, and the supporting plate 6 transmits the horizontal load to the mounting plate 1 through the irregular block 4.

[0029] Please refer to Figure 1The bridge crane assembly includes: a crossbeam 7 extending along the width of a concrete column, the crossbeam 7 being connected to at least a portion of a support assembly via fasteners; the crossbeam 7 extending along a predetermined direction; a slide rail extending along the extension direction of the crossbeam 7 and mounted on the crossbeam 7; and a bridge crane 8 movably mounted on the slide rail along the extension direction of the slide rail.

[0030] By adopting the above technical solution, the detachable fastening connection between the crossbeam 7 and the support plate 6 forms a standardized interface, and the extension direction of the slide rail is consistent with the axis of the crossbeam 7 to ensure the linear motion accuracy of the bridge crane 8. This modular design allows the span of the crane beam to be quickly adjusted by adding or removing crossbeam 7 segments to meet the lifting needs of industrial plants or temporary storage yards with different spans, and the disassembled components meet the transportation size restrictions.

[0031] Working principle:

[0032] Mounting plate 1 is fixed to the surface of concrete column with pre-embedded anchor bolts. By adjusting the vertical position of dovetail block 2 in mounting hole 3, the stabilizing plate 5 is driven to move downward until it is tightly attached to the surface of column. Simultaneously, the vertical height of irregular block 4 is adjusted so that the support plate 6 reaches the preset horizontal elevation. At this time, the wedge-shaped surface of dovetail block 2 generates self-locking friction with mounting hole 3, and the asymmetrical contour of irregular block 4 forms lateral constraint with the guide groove of mounting plate 1, together constructing a two-way locking state.

[0033] The vertical load generated by the bridge crane 8 when running on the slide rail is transmitted to the support plate 6 through the crossbeam 7. It is decomposed into vertical pressure and horizontal shear force through the contact surface between the protrusion of the irregular block 4 and the mounting plate 1. The lateral sway load is converted into the normal pressure of the inner wall of the mounting hole 3 by the stabilizing plate 5 through the inclined self-locking effect of the dovetail block 2, so as to avoid loosening of the connection. The separate design of the support plate 6 and the stabilizing plate 5 realizes the separation of the horizontal / vertical load paths, ensuring the rationality of the structural stress.

[0034] After releasing the fasteners between the crossbeam 7 and the support plate 6, the irregular block 4 is lifted vertically to detach the support plate 6 from the mounting plate 1; simultaneously, the dovetail block 2 is lifted to release the wedge self-locking, and the stabilizing plate 5 is then detached from the concrete column surface. All components can be removed vertically without obstruction, and the mounting plate 1 remains on the column for reuse.
