[0002] At present, the connection nodes of box-type steel structure modules are the core of the modules. There are no lifting locks suitable for cross-corner boxes on the market, which means that the lifting points of box-type steel structure modules need to be welded before leaving the factory, and the lifting points need to be cut after on-site lifting. Box-type steel structure modules come in many sizes, and it is necessary to calculate the lifting point positions and increase the strength of the lifting point positions. This leads to a large amount of preparatory work in the early stage and higher labor costs for on-site operations in the later stage, which seriously affects the lifting efficiency and construction costs. Utility Model Content

[0003] In view of the above analysis, the embodiment of the present utility model aims to provide a box-type steel structure module lifting lock to solve the problems of low lifting efficiency and high construction cost of the existing box-type steel structure module with a cross corner box.

[0004] The purpose of this utility model is mainly achieved through the following technical solutions:

[0005] A box-type steel structure module lifting lock is used for lifting a box-type steel structure module with a cross corner box. The box-type steel structure module lifting lock comprises a lifting column, a fixed limit block and a sliding limit block. The lifting column is provided with a limit groove. The middle portion of the sliding limit block slides in the limit groove. The fixed limit block is provided at the bottom of the lifting column and forms a T-shaped structure or a cross structure. The T-shaped structure or the cross structure can be inserted into the cross hole of the cross corner box.

[0006] When the box-type steel structure module is hoisted, the fixed limit block is located in the cross corner piece box and abuts against the top cover of the cross corner piece box, and the bottom of the sliding limit block is clamped in the cross hole.

[0007] Furthermore, the sliding limit block includes a limit plate, a sliding plate and a locking block, the limit plate is arranged at the upper end of the sliding plate, the locking block is arranged at the lower end of the sliding plate, and the sliding plate slides in the limit groove.

[0008] Furthermore, the hanging column includes a first positioning platform, the first positioning platform is connected to the lower end of the hanging column, and the gap between a part of the first positioning platform and the side wall of the hanging column is the limiting groove.

[0009] Furthermore, the hanging column further includes a second positioning platform, which is located below the first positioning platform and connected to the lower end of the hanging column.

[0010] Furthermore, the first positioning platform and the second positioning platform are both U-shaped structures.

[0011] Furthermore, the bottom length of the hanging column is equal to the difference between half the vertical hole length of the cross hole and half the horizontal hole width of the cross hole, and the width of the hanging column is equal to the vertical hole width of the cross hole or 0.5-1mm smaller than the vertical hole width of the cross hole.

[0012] Furthermore, the length of the blocking block is not greater than the length of the cross hole of the cross hole, and the width of the blocking block is equal to the width of the cross hole or is 0.5-1 mm smaller than the width of the cross hole.

[0013] Furthermore, the distance between the bottom surface of the second positioning platform and the top surface of the fixed limiting block is equal to the thickness of the top cover, or is 0.5-1 mm larger than the thickness of the top cover.

[0014] Furthermore, the bottoms of the hanging column and the fixed limit block are both provided with chamfers.

[0015] Furthermore, a hanging hole is provided on the top of the hanging column.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0017] (1) The fixed limit block of the utility model forms a T-shaped structure or a cross-shaped structure with the bottom of the lifting column, and the sliding limit block can slide along the limit groove on the lifting column. When the box-type steel structure module is lifted, the T-shaped structure or the cross-shaped structure is inserted into the cross hole and the top cover of the cross corner box is used to limit the fixed limit block. The sliding limit block is stuck in the cross hole to prevent the lifting lock from swinging back and forth, and can quickly achieve connection with the cross corner box, reducing the preliminary preparation work, improving the lifting efficiency, reducing the construction cost, and facilitating the operation of workers.

[0018] (2) The sliding limit block of the utility model includes a limit plate, a sliding plate and a locking block. The limit plate is arranged at the upper end of the sliding plate, and the locking block is arranged at the lower end of the sliding plate. The sliding plate slides in the limit groove. When it is necessary to lift the box-type steel structure module, the lifting lock moves to the top of the cross corner box, and the T-structure or the cross structure is aligned with the cross hole and inserted, and continues to move downward so that the top of the fixed limit block does not interfere with the top cover. Then the lifting lock is moved backward so that the lifting column moves along the vertical hole of the cross hole. During this process, the top cover lifts the locking block. When the locking block moves to the horizontal hole of the cross hole, the locking block falls and is stuck in the horizontal hole of the cross hole. The limit plate is stuck above the limit groove, and the locking block no longer falls downward, thereby limiting the forward and backward movement of the lifting column.

[0019] (3) The utility model includes a first positioning platform and a second positioning platform, both of which are connected to the lifting column. The second positioning platform is located below the first positioning platform. After the bottom of the lifting lock is inserted into the cross hole, the lifting lock is pushed to the lifting position. After rough positioning using the cross hole, the first positioning platform, the second positioning platform and the positioning block are finely positioned, and the lifting operation is carried out in conjunction with the lifting device. The positioning is fast and the lifting is accurate and reliable.

DETAILED DESCRIPTION

[0030] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0031] A specific embodiment of the present invention, combined with Figures 1-6 As shown, a box-type steel structure module lifting lock is disclosed, which is used for lifting box-type steel structure modules with cross corner box. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the box-type steel structure module lifting lock includes a lifting column 1, a fixed limit block 2 and a sliding limit block 3. A limit groove 11 is provided on the lifting column 1. The middle part of the sliding limit block 3 slides in the limit groove 11. The fixed limit block 2 is arranged at the bottom of the lifting column 1 to form a T-structure or a cross structure. The T-structure or the cross structure can be inserted into the cross hole 101 of the cross corner piece box 100. When the box-type steel structure module is lifted, the fixed limit block 2 is located in the cross corner piece box 100 and abuts against the bottom surface of the top cover 102 of the cross corner piece box 100. The bottom of the sliding limit block 3 is stuck in the cross hole 101.

[0032] Compared with the prior art, the box-type steel structure module lifting lock provided in this embodiment has a fixed limit block 2 and the bottom of the lifting column 1 forming a T-structure or a cross structure, and the sliding limit block 3 can slide along the limit groove 11 on the lifting column 1. When lifting the box-type steel structure module, the T-structure or the cross structure is inserted into the cross hole 101 and the top cover 102 of the cross corner piece box 100 is used to limit the fixed limit block 2. The sliding limit block 3 is stuck in the cross hole 101 to prevent the lifting lock from swinging back and forth, and can quickly achieve connection with the cross corner piece box 100, reducing preliminary preparation work, improving lifting efficiency, reducing construction costs, and facilitating workers' operation.

[0033] In order to facilitate the connection with the spreader, such as Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a hanging hole 12 is provided at the top of the hanging column 1. In order to facilitate connection with the cross hole 101, a first chamfer 13 is provided at the bottom of the hanging column 1 to avoid collision between the bottom of the hanging column 1 and the top cover 102 at the same or similar lengths.

[0034] Preferably, the top of the hanging column 1 is a circular disk, and the lower end of the circular disk is a rectangular parallelepiped. In other words, the hanging column 1 includes a circular disk and a rectangular parallelepiped, with the circular disk being located at one end of the rectangular parallelepiped and a fixed stop 2 being located at the other end. The circular disk and the rectangular parallelepiped are integrally formed to form the hanging column 1.

[0035] The fixed limit block 2 is a rectangular parallelepiped structure. There are one or two fixed limit blocks 2. When there is one fixed limit block 2, a groove is provided at the bottom of the hanging column 1. The groove is arranged opposite to the first chamfer 13. The fixed limit block 2 is arranged at the groove and is connected to the bottom of the hanging column 1 to form a T-shaped structure or a cross structure. When there are two fixed limit blocks 2, the two fixed limit blocks 2 are symmetrically arranged about the lower part of the hanging column 1 and form a T-shaped structure or a cross structure with the bottom of the hanging column 1. When the side wall of the fixed limit block 2 is flush with the bottom side wall of the hanging column 1, the fixed limit block 2 and the bottom of the hanging column 1 form a T-shaped structure; when the side wall of the fixed limit block 2 is not flush with the bottom side wall of the hanging column 1, the fixed limit block 2 and the bottom of the hanging column 1 form a cross structure. A T-shaped structure is preferred. Exemplarily, the fixed limit block 2 is fixed to the hanging column 1 by welding.

[0036] In order to prevent the fixed limit block 2 from hitting the side wall of the cross hole 101, Figure 2 、 Figure 3 and Figure 4 As shown, a second chamfer 21 is provided at the bottom along the length direction of the fixed limiting block 2 .

[0037] like Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, the sliding limit block 3 includes a limit plate 31, a sliding plate 32, and a blocking block 33. The limit plate 31 is provided at the upper end of the sliding plate 32, and the blocking block 33 is provided at the lower end of the sliding plate 32. The sliding plate 32 slides in the limit groove 11. Preferably, the limit plate 31 and the blocking block 33 are both vertically connected to the sliding plate 32.

[0038] The bottom length of the hanging column 1 is equal to the difference between half the length of the vertical hole of the cross hole 101 and half the width of the horizontal hole of the cross hole 101. The width of the hanging column 1 is equal to the width of the vertical hole of the cross hole 101 or is 0.5-1 mm smaller than the vertical hole width. The length of the blocking block 33 is no longer than the length of the horizontal hole of the cross hole 101, and the width of the blocking block 33 is equal to the width of the horizontal hole of the cross hole 101 or is 0.5-1 mm smaller than the width of the horizontal hole of the cross hole 101.

[0039] When it is necessary to lift the box-type steel structure module, the lifting lock is moved to the top of the cross corner box 100, the T-structure or the cross structure is aligned with the cross hole 101 and inserted, and continues to move downward so that the top of the fixed limit block 2 does not interfere with the top cover 102, and then the lifting lock is moved backward so that the lifting column 1 moves along the vertical hole of the cross hole 101. During this process, the top cover 102 lifts the blocking block 33. When the blocking block 33 moves to the horizontal hole of the cross hole 101, the blocking block 33 falls and is stuck in the horizontal hole of the cross hole 101, and the limiting plate 31 is stuck above the limiting groove 11. The blocking block 33 no longer falls downward, and the lifting column 1 can no longer move backward or forward.

[0040] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the hanging column 1 also includes a first positioning platform 14. The first positioning platform 14 is a U-shaped structure. The first positioning platform 14 is connected to the lower end of the hanging column 1. A portion of the first positioning platform 14 has a gap with the side wall of the hanging column 1 to form a limiting groove 11. The height of the first positioning platform 14 needs to meet the requirement that when the bottom of the limiting plate 31 contacts the top of the first positioning platform 14, the positioning block 33 is just stuck in the horizontal hole of the cross hole 101. That is, the distance between the bottom surface of the limiting plate 31 and the top surface of the positioning block 33 is equal to the sum of the thickness of the first positioning platform 14 and the distance between the first positioning platform 14 and the top surface of the top cover 102.

[0041] In order to more accurately locate the falling position of the hanging column 1, Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the hanging column 1 also includes a second positioning platform 15. The second positioning platform 15 is a U-shaped structure. The second positioning platform 15 is located below the first positioning platform 14 and is connected to the lower end of the hanging column 1. The distance between the bottom surface of the second positioning platform 15 and the top surface of the fixed limit block 2 is equal to the thickness of the top cover 102, or slightly larger than the top cover 102 (e.g., 0.5-1mm). When the second positioning platform 15 contacts the top of the top cover 102, the fixed limit block 2 is just below the top cover 102. Under the positioning of the second positioning platform 15, the falling distance of the hanging column 1 can be accurately limited, and the position of the hanging lock can be quickly and accurately determined.

[0042] In this embodiment, a fixed limit block 2 and a sliding limit block 3 are provided in combination with the structure of the cross corner piece box 100. After the bottom of the lifting lock is inserted into the cross hole 101, the lifting lock is pushed to a dedicated position (i.e., the lifting position). After rough positioning using the cross hole 101, the first positioning platform 14, the second positioning platform 15 and the positioning block 33 are used for fine positioning, and the lifting operation is carried out in conjunction with the lifting equipment. The positioning is fast and the lifting is accurate and reliable.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
