Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary equipment for tower cranes, and specifically to a lifting beam connection structure for a tower crane system. Background Technology
[0002] In tower crane installation and jacking operations, the jacking beam is the core load-bearing component. Its function is to support the jacking frame and achieve the raising and lowering of the entire superstructure through the hydraulic system. The connection between the jacking beam and the standard tower crane section must be firm, reliable, and easy to assemble and disassemble. Traditional connection methods often use simple pin-shaft direct connections, which have limited structural strength and stability. Under complex working conditions, stress concentration can easily occur, and the installation and disassembly process is not convenient enough, posing certain safety hazards. Summary of the Invention
[0003] This utility model primarily addresses the shortcomings of existing technologies by providing a lifting beam connection structure for tower crane systems. This structure is characterized by its stable structure, high load-bearing capacity, high installation and disassembly efficiency, and safety and reliability. It solves the problems of insufficient strength, poor stability, and inconvenient assembly and disassembly in existing lifting beam connection structures.
[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions: A lifting beam connection structure for a tower crane system includes a lifting beam with connecting assemblies on both sides of its upper end. Each connecting assembly includes an outer end plate with a pin extending from the outer end of the lifting beam. An inner end plate, welded and fixed to the lifting beam, is located between the outer end plate and the outer end plate. A control rod, threadedly inserted into the pin, is located between the inner and outer end plates. By rotating the control rod, the relative position of the pin is adjusted, thereby enabling rapid locking or unlocking of the entire connecting assembly.
[0005] Preferably, side plates are provided between the inner end plate and the outer end plate on both sides, and the inner end plate, side plates, and outer end plate form a frame structure.
[0006] Preferably, the upper end of the pin is provided with a top plate that is welded and fixed to the side plate at one end. The top plate acts as a limiter for the control rod. The top plate forms a mechanical limit on the upper end of the control rod, effectively preventing the control rod from loosening or accidentally dislodging under vibration or external force, thus providing a double safety measure.
[0007] Preferably, the lifting beam is provided with a vertical support plate in the middle, which is welded and fixed to the upper and lower inner walls of the lifting beam.
[0008] Preferably, the vertical support plate is provided with inclined support plates on both sides, which are welded and fixed to the upper and lower inner walls of the lifting beam.
[0009] Preferably, the upper middle part of the lifting beam is provided with a pair of lifting lugs that are welded and fixed perpendicularly to the lifting beam. This provides convenient lifting points for the hoisting, transportation, and installation of the entire lifting beam.
[0010] This invention can achieve the following effects: This invention provides a lifting beam connection structure for a tower crane system, which, compared with existing technologies, features a stable structure, high load-bearing capacity, high installation and disassembly efficiency, and high safety and reliability. It solves the problems of insufficient strength, poor stability, and inconvenient assembly and disassembly in existing lifting beam connection structures. Attached Figure Description

[0016] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0017] Example: Figure 1-4 As shown, a lifting beam connection structure for a tower crane system includes a lifting beam 2. A vertical support plate 4, welded and fixed to the upper and lower inner walls of the lifting beam 2, is located in the middle of the lifting beam 2. Inclined support plates 5, welded and fixed to the upper and lower inner walls of the lifting beam 2, are located on both sides of the vertical support plate 4. A pair of lifting lugs 3, welded and fixed perpendicularly to the lifting beam 2, are located at the middle of the upper end of the lifting beam 2. Connecting components 1 are located on both sides of the upper end of the lifting beam 2. Each connecting component 1 includes an outer end plate 10, with a pin 11 extending from the outer end of the lifting beam 2 on the outer end plate 10. An inner end plate 6, welded and fixed to the lifting beam 2, is located between the outer end plate 10 and the lifting beam 2. Side plates 9 are located between the inner end plate 6 and the outer end plate 10. The inner end plate 6, side plates 9, and outer end plate 10 form a frame structure. A control rod 7, threadedly connected to the pin 11, is located between the inner end plate 6 and the outer end plate 10. The upper end of the pin 11 is provided with a top plate 8 that is welded and fixed to the side plate 9. The top plate 8 plays a limiting role for the control rod 7.
[0018] In summary, the lifting beam connection structure of this tower crane system features structural stability, high load-bearing capacity, high installation and disassembly efficiency, and high safety and reliability. It solves the problems of insufficient strength, poor stability, and inconvenient assembly and disassembly in traditional lifting beam connection structures.
[0019] Stable structure and strong load-bearing capacity: The box-shaped frame structure composed of inner end plates, outer end plates and side plates, as well as the vertical support plates and inclined support plates inside the lifting beam, form a multi-strength system, which makes the entire connection structure have extremely high structural strength, rigidity and stability, and can safely withstand the huge loads during the lifting process.
[0020] Reliable connection and high safety: The threaded connection between the control rod and the pin is more secure and less prone to loosening compared to a simple plug-in connection. The top plate provides double protection, effectively preventing accidental failure of critical components and improving operational safety.
[0021] Easy assembly and disassembly, improved efficiency: The connecting components are designed with a modular structure, which can be quickly locked and released by rotating the control rod, greatly simplifying the installation and disassembly process, shortening the auxiliary time for tower crane lifting operations, and improving work efficiency.
[0022] Uniform stress distribution and long service life: The internal support plate structure effectively disperses stress concentration, avoids premature local damage, and extends the service life of the lifting beam and connecting structure.
[0023] Functional integration and reasonable design: It integrates multiple functions such as connection, reinforcement, limit and lifting into one, with a compact structure, reasonable design, and is easy to manufacture and maintain.
[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the essential characteristics of the invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
