Description

Technical Field

[0001] This utility model relates to the field of linkage mechanism technology, specifically a novel linkage mechanism for a folding boom truck crane. Background Technology

[0002] In many fields such as modern engineering construction, logistics transportation, and rescue and disaster relief, articulated boom truck-mounted cranes have been widely used due to their flexible operating range, strong adaptability, and convenient mobility. However, with the rapid development of the industry and the increasing demands of operations, the linkage mechanism of traditional articulated boom truck-mounted cranes has gradually revealed a series of limitations.

[0003] Traditional linkage mechanisms are often designed with a focus on basic force transmission and motion realization. Their relatively fixed structure makes it difficult to meet the demands of complex and ever-changing working conditions. For example, under different lifting weights, lifting heights, and operating angles, traditional linkage mechanisms cannot automatically and accurately adjust their mechanical properties, thus limiting the overall working efficiency of the crane. Summary of the Invention

[0004] The purpose of this utility model is to provide a novel linkage mechanism for a folding boom truck crane. By installing the linkage mechanism and the support rotation mechanism, and then installing the lifting device with the linkage mechanism, the linkage mechanism can achieve automatic, high-precision and high-flexibility movement, thereby solving the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel linkage mechanism for a folding boom truck-mounted crane, comprising:

[0007] A supporting rotation mechanism is provided, the upper end of which is connected to a linkage mechanism, and the other end of the linkage mechanism is provided with a hoisting device;

[0008] The linkage mechanism includes a rotating column, the upper end of which is connected to a support arm. A base cylinder is provided on the support arm. The other end of the support arm and the base cylinder is connected to a folding arm. A telescopic cylinder is provided on the folding arm. A connecting plate is connected to the other end of the folding arm and the telescopic cylinder. A connecting arm is also connected to the connecting plate.

[0009] As a further technical solution of this utility model, the connecting arm is located on one side of the telescopic arm one. The telescopic arm one is provided with a telescopic cylinder one and a telescopic cylinder two. The telescopic arm one is provided inside the telescopic arm two, and the telescopic arm two is provided inside the telescopic arm three. The other end of the telescopic cylinder one is connected to the telescopic arm two, and the other end of the telescopic cylinder two is connected to the telescopic arm three.

[0010] As a further technical solution of this utility model, the end of the telescopic arm three is connected to the first mounting base. The upper end of the first mounting base is provided with a rotary turbine seat. A small electrical box and a rotary motor are provided on one side of the rotary turbine seat, and a rotary chassis is installed on the upper end of the rotary turbine seat.

[0011] As a further technical solution of this utility model, a drive arm seat is installed on the upper end of the rotating chassis, the drive arm seat is connected to the boom, and a speed reducer is provided on both sides of the drive arm seat.

[0012] As a further technical solution of this utility model, the drive arm seat is also connected to a fixed connecting rod. The fixed connecting rod and the upper end of the upper arm are connected to the arm seat. One end of the arm seat is provided with multiple rotating arm motors, and the other end is provided with a forearm rotating shaft seat. The forearm rotating shaft seat is rotatably connected to the forearm, and the other end of the forearm is provided with a second mounting seat.

[0013] As a further technical solution of this utility model, the bottom of the rotating column is provided with a rotating seat, the bottom of the rotating seat is fixedly connected to the H-shaped mounting frame, the interior of the H-shaped mounting frame is provided with an H-shaped mounting plate, each of the four ends of the H-shaped mounting plate is provided with a lifting cylinder, and the bottom of the lifting cylinder is provided with a telescopic base.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In use, this invention first lifts the folding arm upwards using a base cylinder on the support arm. After being lifted, the folding arm moves from a folded state to a horizontal state. Then, the extension of the telescopic cylinder on the folding arm moves the connecting plate, which in turn causes the connecting arm to extend outwards. The connecting arm, in turn, causes the telescopic arm to extend outwards. Telescopic cylinders one and two on the telescopic arm can control the outward extension of telescopic arm two and telescopic arm three, respectively. A rotating column is located at the bottom of the support arm, and a rotating seat is located at the bottom of the rotating column, which can rotate the support arm, thereby causing the folding arm, connecting arm, and telescopic arm one to rotate. Compared with a straight boom crane, it can achieve more complex actions by folding and extending the boom, such as lifting and moving goods horizontally to a designated position in a narrow space, offering greater flexibility.

[0016] This utility model features a rotating turbine seat under a rotating chassis. A rotating motor drives the rotating turbine seat to rotate, which in turn drives the rotating chassis above to rotate, thereby rotating the drive boom seat. Reducers on both sides of the drive boom seat can adjust the angle between the boom and the drive boom seat. Multiple rotating boom motors on the forearm seat drive the forearm to rotate. A second mounting seat at the other end of the forearm can install different lifting heads. The multi-axis configuration of the lifting device can improve the lifting flexibility of the folding boom truck crane. When the second mounting seat is equipped with a welding head or a spraying head, it can complete fine and complex welding and spraying tasks in a confined space, improving its versatility.

[0017] This utility model features an H-shaped mounting bracket with an H-shaped mounting plate inside. Lifting cylinders are located at the four ends of the H-shaped mounting plate. These lifting cylinders, in conjunction with a telescopic base, allow for adjustment of the lifting height of the H-shaped mounting bracket. By extending and retracting the lifting cylinders, the H-shaped mounting plate is vertically raised and lowered, transferring the weight of the folding boom truck crane to the ground and providing stable support for the crane. This ensures safe and reliable lifting operations. The H-shaped design of the mounting bracket also enhances the overall stability of the folding boom truck crane. Attached Figure Description
