Description

Technical Field

[0001] The utility model relates to the field of tower cranes, in particular to a tower body reinforcement structure of a tower crane. Background Art

[0002] A tower crane is a device used to lift and transport heavy materials on a construction site. It is usually composed of a higher vertical tower body, an arm and a clamp that can move in the horizontal direction. An attachment device is usually provided between the tower body and the building to reinforce the tower body of the tower crane. Comparative document: CN 213651678U, proposes a tower crane attachment frame support reinforcement device. During installation, the sleeve is sleeved onto a fixed plate to complete the installation of the support arm. In this way, the traditional method of installing the support arm by bolts is changed, thereby improving the installation efficiency. The problem with the above technical solution is that the device will directly contact the concrete support column during the installation process, so that in the subsequent use process, the device will cause friction between the concrete column, thereby causing the concrete column to be lost. At the same time, the stress it is subjected to during use will act on the outside of the frame, and the stress it is subjected to cannot be distributed to the greatest extent, so deformation is very likely to occur during long-term use. Utility Model Content

[0003] The purpose of the utility model is to solve the following problems existing in the prior art: the device will come into direct contact with the cement support column during installation, so that in the subsequent use, friction will occur between the device and the cement column, resulting in loss of the cement column; at the same time, the stress it is subjected to during use will act on the outside of the frame, and the stress cannot be distributed to the greatest extent, so that deformation is very likely to occur during long-term use.

[0004] In order to solve the problems existing in the prior art, the utility model provides a tower crane tower reinforcement structure, including a fixed frame, a pressure dividing plate and an insertion rod, a buffer pad is provided on the inner side of the fixed frame, a plurality of groups of pressure dividing plates are equidistantly provided on the outer side of the fixed frame, two groups of connecting plates are provided on both sides of the fixed frame, an insertion rod is provided on the inner side of the connecting plate, a rod sleeve is provided on the outer side of the insertion rod, a pin is provided on the inner side of the rod sleeve, and a plurality of groups of limit rods are equidistantly provided on the inner side of the fixed frame.

[0005] Furthermore, the buffer pad is made of rubber material, and the contact area between the fixed frame and the supporting cement column can be buffered by the buffer pad.

[0006] Furthermore, a plurality of groups of preset holes are provided on the inner side of the pressure dividing sheet, and the stress on the fixed frame can be dispersed through the pressure dividing sheet.

[0007] Furthermore, two groups of through holes are provided at both ends of the insertion rod, so that the insertion rod can be used to conveniently connect and fix the externally connected hydraulic rod.

[0008] Furthermore, a threaded structure is provided on the outer side of the latch pin, and the latch pin is used to fix the rod sleeve and the inserted rod.

[0009] Furthermore, both ends of the limiting rod are provided with a threaded structure, and the limiting rod is used to fix the fixing frame.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model can effectively absorb part of the vibration and impact force through the buffer pad, thereby reducing the vibration and noise caused by the direct contact between the fixed frame and the supporting cement column, reducing the wear between them, and extending the service life of the structure. At the same time, when there are some unevenness or height differences in the supporting cement column, the buffer pad can also play a certain filling and adjustment role, making the connection more stable. At the same time, the buffer pad can reduce the direct friction between the metal structure and the cement column, reducing friction loss and maintenance costs.

[0012] The utility model can expand the force-bearing area through the pressure-dividing sheet, thereby reducing the pressure and stress on the local area of ​​the fixed frame, which is beneficial to alleviating possible local deformation or damage, and makes the force on the fixed frame uniform by dispersing the pressure, which helps to improve its overall stability and durability. The dispersed force will be transmitted to the supporting structure more evenly, which is beneficial to reducing the stress concentration of the local panels or columns of the supporting structure, thereby extending the service life of the supporting structure.
