Description

Technical Field

[0001] The utility model relates to the technical field of heavy object hoisting, in particular to an adjustable hoisting beam. Background Art

[0002] The hoisting beam is the most commonly used tool for transporting materials in modern technology. Whether in industrial sites or decoration sites, a hoisting beam is required to transport materials, which can help operators reduce the frequency of transporting materials and reduce the weight of handling. Therefore, the hoisting beam has strong practicability and a wide range of applications.

[0003] In the patent with the publication number CN110356970A, an adjustable hoisting beam is proposed. In this patent, it includes a track, a monorail crane, a first load-carrying trolley, a second load-carrying trolley, a sprocket shaft, a sprocket, a hoisting beam hydraulic valve, a chain sling, a hook, a reset button, a rotating plate, a threaded rod, a support rod, a hydraulic pipeline, a main control valve block, a solenoid valve, and a controller. It can control the hoisting winch through a hydraulic control component. When the monorail crane is in a stopped state and reaches the position where hoisting is required, the solenoid valve in the hydraulic control component receives the instruction sent by the controller. The solenoid valve controls the inlet and outlet of the oil circuit. The oil circuit enters the main control valve block through the hydraulic pipeline. The main control valve block controls the pressure and speed of the oil circuit. At this time, the oil circuit enters the hoisting beam hydraulic valve through the hydraulic pipeline. By controlling the hoisting beam hydraulic valve, it controls the oil circuit to enter the hoisting winch through the hydraulic pipeline, so that the chains on both sides of the hoisting winch drive the hook to hoist the item. The use of the hydraulic control component can control the lifting of the hoisting winch, prevent people from being injured during the hoisting process, and play a good protective role. At the same time, by using the limit groove on the beam body, the position of the sprocket box can be adjusted to hoist items of different sizes. However, there are still the following problems in this patent:
