Description

Technical Field

[0001] The present application relates to the technical field of clamping equipment, and specifically discloses a heavy-duty box-type column flipping clamp. Background Art

[0002] Steel structure box columns are made of steel materials. They are one of the main types of building structures. They are heavy-duty box columns. They are easy to construct and are widely used in large factories, stadiums, super high-rise buildings, etc. The existing box columns are hollow inside. After welding, the box columns are uniformly placed between several parallel support blocks and lifted by a crane for transfer.

[0003] And when assembling the building structure, the box columns need to be aligned to correspond to each surface of the box columns for assembly. Therefore, before the box columns are lifted by the crane for assembly, they need to be flipped to align the position of the box columns to be assembled with the positions of the installed box columns.

[0004] The four sides of the box-type column are smooth, and it is not easy to fix and clamp the corners of the box-type column during the flipping process. Therefore, the two ends of the box-type column are often clamped as the force application points during the flipping process. However, since the steel plate is easy to deform, and the box-type column is usually clamped by fixing only one side in the prior art, the box-type column at this force point is easy to deform after being subjected to force during the flipping process.

[0005] Therefore, in view of this, the inventor provides a heavy-duty box-type column flipping fixture to solve the above-mentioned problem. Utility Model Content

[0006] The utility model aims to solve the problem that the traditional heavy box-type column is only clamped and fixed at the same side points of the openings at both ends when flipping, which easily causes deformation of the box-type column at the stress point during the flipping process.

[0007] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a heavy-duty box-type column flipping clamp, including a clamping structure respectively clamped at the opening diagonals at both ends of the box-type column, the clamping structure including a corner plate arranged on the inner side of the box-type column and abutting against the inner wall of the inner corner of the box-type column, a back plate arranged on the outer side of the box-type column and aligned with one side of the corner plate, and a connecting piece detachably connected between the back plate and the corner plate on the outer side of the box-type column and used to clamp the back plate and the side wall of the corner plate on the same side, and a connecting plate for fixing a steel cable is fixedly connected to the back plate.

[0008] Furthermore, the outer corner of the corner plate located on the inner side of the box-type column abuts against the inner wall of the inner corner of the box-type column, and an inclined groove is opened at the outer corner of the corner plate located on the outer side of the box-type column to form an inclined table surface that does not abut against the inner wall of the inner corner of the box-type column.

[0009] Furthermore, a supporting structure is provided between the corner plates at two diagonal sides of the same end of the box-type column.

[0010] Furthermore, the supporting structure includes a support platform fixedly connected to the inner side of the corner plate, a first sleeve fixedly connected to the inner side of the support platform on one side, a second sleeve fixedly connected to the inner side of the support platform on the other side, and a connecting rod connected to the first sleeve for rotation limiting, the connecting rod extends out of the first sleeve and has an external thread, and the second sleeve has an internal thread engaged with the external thread.

[0011] Furthermore, a section of the connecting rod extending outside the first sleeve is also provided with a swivel.

[0012] Furthermore, the support platform is a right-angled triangular pyramid that fits the inner wall of the corner plate.

[0013] Furthermore, the first sleeve and the second sleeve are both rectangular and aligned with each other.

[0014] The principle and effect of this scheme are:

[0015] 1. Compared with the prior art, the utility model uses a clamping structure to clamp the diagonals of both ends of the box-type column, and the specific installation position is: a group of corner plates and abutment plates are installed at the top side corners of the box-type column facing the direction to be turned, and the abutment plates are installed on the top end face of the box-type column, and a group of corner plates and abutment plates are installed at the bottom corners of the box-type column opposite to the side corners, and the abutment plates are installed on the side of the box-type column, and then the connecting plate on the diagonal clamping structure is pulled by a steel cable, and the box-type column is flipped by a crane.

[0016] 2. Compared with the prior art, the utility model clamps the side of the box column by surface contact through the corner plate and the abutment plate, and realizes the fastening of the corner plate and the abutment plate through the connecting piece. During the flipping process, when the corner plate abuts against the inner side of the corner of the box column, the contact area between the corner plate and the box column can be increased by the abutment plate, so that the force can be dispersed to ensure that the clamping position of the box column will not be deformed. This solves the problem that the traditional heavy box column is only clamped and fixed by the same side point of the openings at both ends during flipping, which easily causes the box column at the force point to deform during the flipping process.

[0017] 3. Compared with the prior art, the present invention further installs a support structure between the two corner plates at the same end, which further supports the corner plates, and then supports the box-type column to prevent the box-type column from being squeezed and deformed. The support structure can also adjust the distance between the first sleeve and the second sleeve and the corner plates on both sides by rotating the connecting rod and the threaded connection relationship between the external thread of the connecting rod and the internal thread of the second sleeve, so as to adapt to box-type columns of different sizes.

Specifically, the clamping structure includes a corner plate, an abutment plate, a connecting piece installed between the corner plate and the abutment plate, and a connecting plate 10 welded to the abutment plate.

[0025] In this embodiment, the box column 1 needs to be flipped to the left, and the corner plates are respectively installed at the corner on the left side of the top end of the box column 1, named as the driven corner plate 2 and the corner on the right side of the bottom end of the box column 1, named as the active corner plate 4.

[0026] The two sides of the driven corner plate 2 and the active corner plate 4 are respectively attached to the inner wall of the box column 1 on the side where they are located. The top surface of the box column 1 above the driven corner plate 2 is installed with a driven abutment plate 3, and the side wall of the box column 1 on the right side of the active corner plate 4 is installed with an active abutment plate 5. Two main positioning holes are respectively opened on the two sides of the driven corner plate 2 and the two sides of the active corner plate 4, and two secondary positioning holes are respectively opened on the driven abutment plate 3 and the active abutment plate 5, and the positions of the main positioning holes and the secondary positioning holes are extended to the outside of the box column 1. Two connecting plates 10 are also welded to the end faces of the active abutment plate 5 and the driven abutment plate 3, and two receiving grooves are opened on the connecting plates 10.

[0027] The connecting piece includes a threaded column 11 and nuts installed at both ends of the threaded column 11. Two threaded columns 11 are installed between the active abutment plate 5 and the active corner plate 4 on the same side through two mutually aligned main positioning holes and auxiliary positioning holes, and a nut is tightened on the threaded column 11 outside the main positioning hole and the auxiliary positioning hole. Two threaded columns 11 are also installed between the driven abutment plate 3 and the driven corner plate 2 on the same side through two mutually aligned main positioning holes and auxiliary positioning holes and tightened with nuts.

[0028] In the present embodiment, the outer corners of the active corner plate 4 and the driven corner plate 2 located on the inner side of the box-type column 1 are both against the inner wall of the inner corner of the box-type column 1, and the outer corners of the active corner plate 4 and the driven corner plate 2 located on the outer side of the box-type column 1 are both provided with inclined grooves to form an inclined table surface that does not abut against the inner wall of the inner corner of the box-type column 1.

[0029] A support structure is also installed between the active corner plate 4 and the driven corner plate 2 at the same end of the box column 1. The support structure includes a support platform 12 welded to the inner side of the active corner plate 4 and the driven corner plate 2, a first sleeve 7 welded to the inner side of the right support platform 12, a second sleeve 6 welded to the inner side of the left support platform 12, and a connecting rod 9 mounted and rotatable through the first sleeve 7.

[0030] An inner ring groove is formed in the first sleeve 7, and an inner ring stage is formed integrally with the connecting rod 9 located at the inner side of the inner ring groove and can slide on the inner wall of the inner ring groove. A rotating ring 8 is formed integrally with the connecting rod 9 extending out of the first sleeve 7, and an external thread is formed on the connecting rod 9 located outside the rotating ring 8. An internal thread meshing with the external thread is formed in the second sleeve 6, and the left end of the connecting rod 9 extends into the second sleeve 6 and is connected to the second sleeve 6 by threads.

[0031] In this embodiment, the support platform 12 is a right-angled triangular pyramid that fits the inner wall of the corner plate. The first sleeve 7 and the second sleeve 6 are both rectangular parallelepiped and the first sleeve 7 and the second sleeve 6 are aligned with each other.

[0032] When the utility model is used, the size of the openings at both ends of the box-shaped column 1 is first determined, and then the rotating ring 8 on the connecting rod 9 is screwed while the active corner plate 4 and the driven corner plate 2 are controlled to remain stationary. The intervals between the first sleeve 7 and the second sleeve 6, the active corner plate 4 and the driven corner plate 2 are adjusted through the threaded connection relationship between the connecting rod 9 and the second sleeve 6, and the active corner plate 4 and the driven corner plate 2 are respectively pressed against the diagonal portions of the box-shaped column 1. In this embodiment, the active corner plate 4 is pressed against the right side of the bottom end of the box-shaped column 1, and the driven corner plate 2 is pressed against the left side of the top end of the box-shaped column 1. On the side, the active abutment plate 5 is installed on the right outer wall of the bottom end of the box-type column 1, and the driven abutment plate 3 is installed on the left end face of the top end of the box-type column 1, and they are fixed with threaded columns 11 and nuts respectively. The active corner plate 4 and the active abutment plate 5, the driven corner plate 2 and the driven abutment plate 3 are used to clamp the two side walls of the box-type column 1 respectively. The heavy box-type column 1 can be flipped over by passing the steel cable through the connecting plate 10 and connecting the crane. In addition, the active corner plate 4 is the main force application point, and the driven corner plate 2 is the secondary force application point. The box-type column 1 is pulled by the main force application point and flipped to the left.

[0033] During the flipping process, when the active corner plate 4 and the driven corner plate 2 abut against the inner side of the corner of the box column 1, the active abutment plate 5 and the driven abutment plate 3 increase the contact area with the box column 1, so that the force is dispersed to ensure that the clamping position of the box column 1 will not be deformed.
