Description

Technical Field

[0001] This invention relates to the field of tower crane installation technology, specifically to a high-safety tower crane installation lifting mechanism and its lifting method. Background Technology

[0002] Tower cranes, also known as tower hoists, are one of the most common pieces of equipment on construction sites. During the process of raising and installing tower cranes, a lifting structure is often used to lift the top of the tower crane by increasing the number of standard components, thereby raising the tower crane.

[0003] When lifting a tower crane, the structure above the lifting frame (such as the operator's cab and boom) needs to remain stable. An unstable upper structure can easily cause the lifting structure to tilt and sway. In this case, the tower crane is prone to losing balance, generating swaying force, increasing the risk of overturning, and posing a threat to operators and the surrounding environment. In the existing technology, the swing of the boom is controlled and locked by the operator's cab to achieve the purpose of stabilizing the upper structure. However, when the tower crane is high, the wind force at high altitudes is strong. Even if the swing of the boom is controlled and locked, the upper structure will still be blown and swayed by the wind, thereby reducing the overall safety of tower crane installation and lifting.

An arc-shaped support member is provided on one side of the crossbeam, and a side clamping tooth is provided on one side of the arc-shaped support member. A wind speed measuring component group is provided on one side of the operating platform for measuring wind speed.

The triangular support has a pivot at the position corresponding to the upper support rod, and the triangular support is connected to the upper support rod via the pivot. The end of the first hydraulic rod away from the lower support rod has a pivot at the position corresponding to the triangular support, and one end of the first hydraulic rod is connected to the triangular support via the pivot. Two sets of side clamping teeth are provided, and the two sets of side clamping teeth are symmetrically connected to both sides of the triangular support. The two sets of side clamping teeth are in contact with the side of the boom.

[0009] Preferably, the crossbeam is fixed to the side of the lifting frame by bolts, the crossbeam is provided with a pivot at the position corresponding to the second hydraulic rod, and the crossbeam and the second hydraulic rod are connected by the pivot, the arc-shaped support is provided with a pivot at the position corresponding to the second hydraulic rod, and the second hydraulic rod and the arc-shaped support are connected by the pivot.

[0010] Preferably, the second side clamping tooth is connected to the side of the arc-shaped support member, the second side clamping tooth contacts the side of the boom, one end of the arc-shaped support member contacts the bottom of the boom, and the cross frame is provided with a pivot at the position corresponding to the arc-shaped support member, and the cross frame and the arc-shaped support member are connected by the pivot.

[0011] Preferably, the wind power measurement component assembly includes a wind turbine body, a display panel is provided on one side of the wind turbine body, and a vertical axis wind turbine is provided on one side of the display panel.

[0012] Preferably, the wind turbine body is connected to the control console, the display panel is connected to the wind turbine body, and the vertical axis wind turbine is connected to the top of the wind turbine body via a rotating shaft.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This high-safety tower crane installation and lifting mechanism and its lifting method are equipped with a lifting component assembly. At high altitudes, wind force is strong. Even if the boom's swing is controlled and locked, the upper structure will still sway under the wind, thus reducing the overall safety of the tower crane installation and lifting. In the corresponding lifting component assembly design, when it is necessary to lift the upper boom and cab structure using a lifting frame, the end of the boom connected to the lifting device will face the entry point of the lifting frame. The angle of the boom is locked through the control room in the cab. Then, the operator who is installing the standard components can control the control console to raise the crane. The operator's control console can control the extension and retraction of the first and second hydraulic rods. When the first hydraulic rod is extended, it will lift the triangular support member. The triangular support member, under force, will rotate around the pivot point corresponding to the upper frame position. During rotation, the distance between the triangular support member and the bottom of the boom will gradually decrease. When they are in complete contact, the sides of the triangular support member... The first side clamping tooth contacts both sides of the boom, forming a clamping structure for the boom. The contact of the rear stabilizing component with the boom enhances the relative stability between the rear end of the upper boom and the lifting frame. Controlling the retraction of the second hydraulic rod pulls the arc-shaped support member to rotate around the axis set on the corresponding crossbeam. During rotation, one end of the arc-shaped support member approaches the bottom of the boom. When the arc-shaped support member and the bottom of the boom are fully in contact, the second side clamping tooth contacts the side of the boom. The front stabilizing component clamps the boom, enhancing the relative stability between the front of the boom and the lifting frame. The cooperation of the rear and front stabilizing components improves the stability of the connection between the boom and the lifting frame. When wind blows on the boom, this stability reduces the swaying amplitude of the upper structure, preventing the lifting frame from swaying and becoming unbalanced, thus enhancing the safety of the lifting frame.

[0015] 2. This high-safety tower crane installation and lifting mechanism and its lifting method are equipped with a wind force measurement component group. The main significance of the wind force measurement component group is that it allows operators to easily and quickly view the wind force within the crane's range. When the wind passes by, it blows the vertical axis of the anemometer body to rotate. The rotation of the vertical axis drives the rotating shaft to transmit rotational power to the anemometer body. The anemometer body can obtain the current wind speed by measuring the rotational speed, and then display the wind force on the display panel. When operating the overall lifting frame, the operator can easily view the display panel from the operating platform, thus quickly understanding whether the current wind force is suitable for operation. When the wind force is too strong, the operation of the lifting frame can be stopped in time, thereby further improving the safety of the overall lifting frame operation. Attached Figure Description

[0025] The lifting frame 21 is connected to the operating platform 22. The operating platform 22 is equipped with guardrails around its perimeter. The operating platform 22 is designed to facilitate personnel standing. Operators can stand on the operating platform 22 to operate and control the lifting frame 21 and the control console 23. The lifting frame 21 is an existing frame, which is used only to lift the upper structure of the crane and provides a space for installing standard parts.

[0026] The control console 23 is connected to the operating platform 22. The control console 23 is electrically connected to the first hydraulic rod 241 and the second hydraulic rod 251. The upper frame rod 243 and the lower frame rod 242 are fixed to the side of the lifting frame 21 by bolts. A support rod is connected between the lower frame rod 242 and the upper frame rod 243.

[0027] The lower support rod 242 has a pivot at one end corresponding to the first hydraulic rod 241, and the lower support rod 242 is connected to one end of the first hydraulic rod 241 through the pivot. The triangular support member 244 has a pivot at the position corresponding to the upper support rod 243, and the triangular support member 244 is connected to the upper support rod 243 through the pivot. The end of the first hydraulic rod 241 away from the lower support rod 242 has a pivot at the position corresponding to the triangular support member 244, and one end of the first hydraulic rod 241 is connected to the triangular support member 244 through the pivot. Two sets of side clamping teeth 245 are provided, and the two sets of side clamping teeth 245 are symmetrically connected on both sides of the triangular support member 244. The two sets of side clamping teeth 245 are in contact with the side of the boom 12.

[0028] The cross frame 252 is fixed to the side of the lifting sleeve 21 by bolts. The cross frame 252 is provided with a pivot at the position corresponding to the second hydraulic rod 251, and the cross frame 252 and the second hydraulic rod 251 are connected by the pivot. The arc-shaped support 253 is provided with a pivot at the position corresponding to the second hydraulic rod 251, and the second hydraulic rod 251 and the arc-shaped support 253 are connected by the pivot.

[0029] Side clamping tooth 254 is connected to the side of the arc-shaped support 253. Side clamping tooth 254 contacts the side of the boom 12.

The cross frame 252 is provided with a pivot at the position corresponding to the arc-shaped support 253, and the cross frame 252 and the arc-shaped support 253 are connected by the pivot.

[0030] The wind force measurement component group 03 includes a wind force meter body 31, a display panel 32 is provided on one side of the wind force meter body 31, and a vertical axis wind 33 is provided on one side of the display panel 32. The wind force meter body 31 is existing technology and can be purchased directly in reality. Therefore, how to calculate the current wind force based on the rotation speed of the shaft connected to the vertical axis wind 33 is included in the technology and will not be elaborated further.

[0031] The wind turbine body 31 is connected to the control console 23, the display panel 32 is connected to the wind turbine body 31, and the vertical axis wind 33 is connected to the top of the wind turbine body 31 via a rotating shaft.

[0032] Working Principle: At higher altitudes, wind speeds are high. Even with the swing of the boom 12 locked, the upper structure will still sway under the wind, reducing the overall safety of the tower crane installation and lifting. In the corresponding lifting component group 02, when the upper boom 12 and the operator's cab 13 structure need to be lifted using the jacking frame 21, the end of the boom 12 connected to the lifting device will face the entrance of the jacking frame 21. The angle of the boom 12 will be locked through the control room in the operator's cab 13. Afterwards, the crane can be raised by installing standard components. The operator control console 23 can control the extension and retraction of the first hydraulic rod 241 and the second hydraulic rod 251. When the first hydraulic rod 241 is extended, it will lift the triangular support member 244. The triangular support member 244 will rotate around the pivot point corresponding to the upper frame rod 243. During the rotation, the distance between the triangular support member 244 and the bottom of the boom 12 will get closer and closer. When they are in complete contact, the side clamping teeth 245 on both sides of the triangular support member 244 will contact the sides of the boom 12. The side clamping teeth 245 on both sides can form a clamping structure for the boom 12. Through the contact of the rear stabilizing component 24 with the boom 12, the relative stability between the rear end of the upper boom 12 and the lifting frame 21 can be enhanced. Controlling the retraction of the second hydraulic rod 251 can pull the arc-shaped support 253 to rotate around the pivot of the corresponding crossbeam 252. During the rotation, one end of the arc-shaped support 253 will approach the bottom of the boom 12. When the arc-shaped support 253 and the bottom of the boom 12 are in complete contact, the side clamping teeth 254... The front stabilizing component 25 can clamp the boom 12 and make contact with the side of the boom 12. This front stabilizing component 25 can enhance the relative stability between the front of the boom 12 and the lifting frame 21. The rear stabilizing component 24 and the front stabilizing component 25 work together to improve the stability of the connection between the boom 12 and the lifting frame 21. When the wind blows on the boom 12, this stability can reduce the swaying amplitude of the upper structure, thereby preventing the lifting frame 21 from shaking and becoming unbalanced, and thus enhancing the safety of the lifting frame 21. The main significance of the wind force measurement component group 03 is that it allows operators to easily and quickly view the wind force within the current crane range. When the wind passes by, it will cause the vertical axis wind 33 at the top of the wind force meter body 31 to rotate. The rotation of the vertical axis wind 33 drives the rotating shaft to transmit the rotational power to the wind force meter body 31. The wind force meter body 31 can obtain the current wind speed by measuring the rotational speed, and then display the wind force on the display panel 32. When the operator operates the overall lifting frame 21, since he / she is standing on the operating platform 22, he / she can easily view the display panel 32, thereby quickly understanding whether the current wind force is suitable for operation. When the wind force is too strong, the operation of the lifting frame 21 can be stopped in time, thereby further improving the safety of the overall lifting frame 21 during operation.
