Description

Technical Field

[0001] The invention relates to the technical field of quick assembly of a crane boom, in particular to an assembly mechanism of a crane boom. Background Art

[0002] In recent years, with the rapid development of truck-mounted crane technology and the intelligent and fast production mode, the boom assembly, as an important process in the crane assembly process, has been installed manually, which has seriously affected the work efficiency and increased the labor cost.

[0003] Due to the clearance setting and weight of the boom assembly, the assembly of the boom assembly is very troublesome and time-consuming, which seriously affects the overall efficiency of the whole machine assembly. The traditional way to assemble the boom assembly is mainly to install it by manual adjustment. First, place the basic arm on the ground, use sleepers to adjust the basic arm to keep it roughly vertical, and then use the crane to hoist the arm to be installed to the side of the basic arm. Two workers will assemble it. One person operates the crane to control the arm to be installed to be vertically and smoothly transferred to the approximate centerline position of the basic arm, and the other person presses the tail of the arm to be installed to insert it into the basic arm, and then moves slowly by the crane. The boom assembly is assembled by constantly adjusting the angle of the arm to be installed. This method is not only time-consuming and laborious due to the fuzzy vertical position alignment, and the manual adjustment of the angle depends entirely on personal feeling. The operation may also cause bumps and deformation on the inner wall of the boom due to the inaccuracy of manual operation, which seriously affects the assembly efficiency, accelerates the wear of the boom, and reduces the safety factor.

[0004] Therefore, it is urgent to use a new assembly mechanism of the crane boom. Summary of the invention

[0005] In view of the defects existing in the prior art, the purpose of the present invention is to provide an assembly mechanism for a crane boom. By using this mechanism, while accurately calibrating the center position and maintaining the vertical height, only one operator uses a hydraulic cylinder to adjust and complete the assembly process of the boom assembly simply, quickly and accurately, thereby effectively solving the assembly problem of the boom assembly, saving labor costs, and greatly improving the assembly efficiency and quality of the crane assembly.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: an assembly mechanism for a crane boom, comprising a main operating platform, an auxiliary operating platform and a secondary operating platform arranged in sequence longitudinally, the main operating platform is provided with a clamping mechanism for fixing a basic arm assembly, and the installation port of the basic arm assembly faces the auxiliary operating platform; the auxiliary operating platform is provided with a conveying mechanism and a lifting mechanism, the conveying mechanism is used to convey each arm to be installed to the lifting mechanism in sequence; the lifting mechanism is used to lift the arm to be installed in place, so that the arm to be installed is opposite to the installation port of the basic arm assembly; the secondary operating platform is provided with a pushing mechanism, the pushing mechanism is used to push the arm to be installed lifted by the lifting mechanism into the basic arm assembly.

[0007] Based on the above technical solution, the clamping mechanism includes a fixed clamp, a movable clamp and a screw; the fixed clamp and the movable clamp are arranged relatively spaced apart on the main operating table; the screw is arranged on the main operating table through a support, and the end of the screw is connected to the outer side of the movable clamp, so as to drive the movable clamp to move.

[0008] On the basis of the above technical solution, the outer side surface of the movable clamping plate is connected to the end of the lead screw through a sliding groove.

[0009] On the basis of the above technical solution, a first cushion block for supporting the basic arm assembly is arranged on the main operating table.

[0010] On the basis of the above technical solution, the conveying mechanism includes a conveying belt transversely arranged on the auxiliary operating table and a driving motor for driving the conveying belt to move.

[0011] On the basis of the above technical solution, a plurality of second pads for supporting the arms to be installed are arranged at intervals on the conveyor belt.

[0012] Based on the above technical solution, the lifting mechanism includes a fulcrum cylinder and an adjusting cylinder; the fulcrum cylinder is arranged on the side of the auxiliary operating table close to the main operating table, and the adjusting cylinder is arranged on the side of the auxiliary operating table close to the secondary operating table; the fulcrum cylinder and the adjusting cylinder are both connected to the hydraulic station.

[0013] On the basis of the above technical solution, the pushing mechanism is a longitudinally arranged pushing cylinder.

[0014] The beneficial effects of the present invention are:

[0015] The present invention can fix the basic arm assembly on a main operating table operated by a single person, adjust the vertical height of the arm to be installed by the fulcrum oil cylinder and the adjusting oil cylinder of the auxiliary operating table, and after confirming that the center height of the arm tube is correct, push the arm assembly to be installed into the basic arm by operating the pushing oil cylinder on the secondary operating table. After the assembly is completed, start the transmission device, and transmit the next-level arm to be installed from left to right to the front of the basic arm, adjust the center height of the arm to be installed by adjusting the fulcrum oil cylinder, and after confirming that the height is correct, push the arm assembly to be installed into the basic arm assembly by the pushing oil cylinder.

[0016] Through the above operations, the present invention can complete fast and accurate assembly work, effectively reduce the labor cost and time cost of the assembly work, and greatly improve the assembly efficiency and quality of the crane assembly while ensuring the assembly accuracy.
