[0003] With the acceleration of the industrialization and urbanization processes, as an important hoisting device, cranes play a crucial role in various fields such as engineering construction, logistics transportation, and manufacturing. As the core component of a crane, the pressure-bearing performance of the crane boom is directly related to the safety and stability of the entire hoisting operation. In order to ensure that the pressure-bearing performance of the crane boom meets safety standards and reduce the occurrence of safety accidents, a pressure-bearing detection device for a crane boom is needed.

[0005] In order to achieve the above object, the utility model adopts the following technical scheme:
[0006] A pressure-bearing detection device for a crane boom includes a bottom plate, a robotic arm is arranged on the top of the bottom plate, a laser lamp is arranged on the outer wall of one side of the robotic arm, a mounting block is arranged at the top end of the robotic arm, a fixing plate is arranged on the outer wall of one side of the mounting block, a receiving plate is arranged on one side of the fixing plate, and a camera is arranged at one end of the robotic arm close to the mounting block.
[0007] In this scheme, when the laser lamp is turned on, the light irradiates on the receiving plate, and the position is recorded. A heavy object is hoisted at one end of the robotic arm, and the position where the laser lamp irradiates on the receiving plate is recorded again, and the offset distance of the light spot is obtained, so as to calculate the bending degree of the robotic arm. According to the standard value of the robotic arm material, the data is compared to determine whether it exceeds the standard, thereby detecting the load-bearing capacity of the robotic arm and ensuring the stability and safety of the entire hoisting operation.
[0008] In a preferred embodiment, symmetrically distributed sliding grooves are formed on the outer walls on both sides of the receiving plate. The sliding grooves are slidably connected to the fixing plate. A toothed groove is formed on one outer wall of the receiving plate, and a rectangular groove is formed on one inner wall of the fixing plate. A clamping block is arranged in the rectangular groove, and the bottom of the clamping block fits with the sliding groove. A circular groove is formed on one inner wall of the rectangular groove, and a spring is arranged in the circular groove.
[0009] With the above solution, multiple groups of experiments are conducted by hanging counterweights of different weights and measuring the bending degree under robotic arms of different lengths. When the robotic arm bends significantly, the receiving plate is slid to adjust its position, and the receiving plate is fixed by the clamping block to receive the light spot irradiated by the laser lamp, which is convenient for the inspectors to adjust and use, effectively improving the detection efficiency and accuracy.
