Description

Technical Field

[0001] This utility model relates to a tower crane bearing connection structure, belonging to the technical field of tower cranes. Background Technology

[0002] The tower body of a tower crane is composed of several standard sections connected together. Adjacent standard sections are connected to each other through joints on the main chord. Depending on the different connecting parts of the standard section joints, common tower crane standard section joints can generally be divided into three types: high-strength bolt connection, pin connection, and bearing connection.

[0003] The bearing clamp structure is widely used in connecting standard sections of self-erecting tower cranes, linking the main chord joints of every two standard sections. Its advantages include convenient and quick connection, high tensile load-bearing capacity, and reusability. Traditional bearing clamp devices need to be disassembled during the installation and removal of standard sections. However, the bearing clamps for large towers typically weigh around 50kg or more, making disassembly and transportation cumbersome, time-consuming, and labor-intensive, thus reducing tower installation efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a tower crane bearing connection structure in which the bearing can be rotated and opened and closed. The bearing device only needs to be initially installed on the lower main chord joint, and there is no need for subsequent handling and disassembly, thus solving the problem of frequent disassembly of the bearing device.

[0005] This utility model is achieved through the following technical solution: a tower crane bearing connection structure, including a standard section lower joint, a standard section upper joint, bearing I and bearing II, wherein the standard section lower joint is provided with hinge I, bearing I is provided with hinge II, bearing II is provided with hinge III, hinge II and hinge III are connected to hinge I through connecting rods, and bearing I and bearing II are fixed to the standard section lower joint and standard section upper joint by bolts.

[0006] The standard section lower connector and standard section upper connector are provided with grooves that match bearing I and bearing II, and bearing I and bearing II can be inserted into the standard section lower connector and standard section upper connector through the grooves.

[0007] The lower connector of the standard section is located at the top of the standard section, and a tray is also provided on the horizontal web bar at the top of the standard section, so that the bearing I and bearing II can be placed on the tray when they are opened.

[0008] The aforementioned bearing I can be connected to the lower joint of the standard section via hinge I and hinge II.

[0009] The aforementioned bearing II can be connected to the lower joint of the standard section via hinge I and hinge III.

[0010] Each of the bearing I and bearing II has four bolt holes. When installing bearing I and bearing II, they are fixed on each side by two bolts.

[0011] The advantages of this invention are: it eliminates the need for traditional methods of installing standard tower sections, allowing the bearing plate to be initially installed on the outside of the lower joint, eliminating the need for frequent installation and removal, thus improving installation efficiency. The hinge design allows the bearing plate to rotate and open, providing greater flexibility and a wider range of applications. Attached Figure Description

[0017] like Figures 1 to 3 The tower crane bearing connection structure shown includes a standard section lower connector 1, a standard section upper connector 2, bearing I 3, and bearing II 4. The standard section lower connector 1 is provided with a hinge I 5, the bearing I 3 is provided with a hinge II 6, and the bearing II 4 is provided with a hinge III 7. The hinges II 6 and III 7 are connected to the hinge I 5 by a connecting rod 8. The bearings I 3 and bearing II 4 are connected and fixed to the standard section lower connector 1 and the standard section upper connector 2 by bolts 9.

[0018] The standard section lower connector 1 and standard section upper connector 2 are provided with grooves that match the bearing I 3 and bearing II 4, and the bearing I 3 and bearing II 4 can be inserted into the standard section lower connector 1 and standard section upper connector 2 through the grooves.

[0019] The standard section lower connector 1 is located at the top of the standard section, and a tray 11 is also provided on the horizontal web bar 10 at the top of the standard section. When the bearing I 3 and bearing II 4 are opened, they can be placed on the tray 11.

[0020] The aforementioned bearing I3 can be connected to the lower connector 1 of the standard section via hinge I5 and hinge II6.

[0021] The aforementioned bearing II4 can be connected to the lower connector 1 of the standard section via hinge I5 and hinge III7.

[0022] Each of the bearing I3 and bearing II4 has 4 bolt holes. When installing bearing I3 and bearing II4, they are fixed on both sides by 2 bolts 9.

[0023] Standard section installation steps: Place bearing plate I3 and bearing plate II4 on top of tray 11. Use connecting rod 8 to connect hinge II6 and hinge III7 to hinge I5. Then place the upper standard section in position. Figure 3 As shown, the end face of the upper connector 2 of the standard section is then aligned with the end face of the lower connector 1 of the standard section. After alignment, the bearing I 3 and bearing II 4 are rotated to mate with the upper and lower connectors and then fixed with four bolts 9.

[0024] Standard section disassembly steps: First, remove the connecting bolts 9, open and rotate the bearing I 3 and bearing II 4 onto the tray 11, and separate the upper standard section from the lower standard section.

[0025] This invention eliminates the need for frequent installation and removal of bearing plates, thus improving the installation efficiency of standard sections.
