Description

Technical Field

[0001] The utility model relates to the technical field of construction unloading platforms, in particular to a unloading platform with a weighing alarm system. Background Art

[0002] Unloading platforms are commonly used in the construction industry, primarily for transporting construction materials from high floors in conjunction with cranes. Currently, unloading platforms on the market are marked with a maximum load capacity to prevent construction accidents caused by overloading. However, in actual use, construction workers often have difficulty determining the actual weight of the construction materials to be transported, posing a safety hazard when using unloading platforms. To address this, unloading platforms with overweight alarm systems have been introduced, such as the one disclosed in Patent No. 202320729935.8.

[0003] This type of unloading platform includes a chassis and an unloading platform that can slide relative to the chassis; the front and rear ends of both sides of the unloading platform respectively include rolling mechanisms for front wheels and rear wheels, so that the unloading platform can slide and retract back and forth on the chassis; the unloading platform slides outward to the working state, and when a heavy object is placed on the unloading platform, the unloading platform can be rotated with the front wheel as a fulcrum, so that the rear wheel tilts upward and applies pressure to the pressure sensor above, and an alarm signal can be issued when the pressure reaches a preset pressure value. However, although this type of alarm system requires less modification to the existing unloading platform and can be well modified and processed using the existing unloading platform, the torque change caused by the heavy object placed on the unloading platform and the front wheel, and the difference in the telescopic position of the unloading platform will also cause the torque change between the heavy object and the front wheel, resulting in a large error range in the pressure effect of the rear wheel on the pressure sensor, and it is difficult to intuitively display the weight change reading for the difference in weight of the lower weight. Therefore, further improvement is needed. Utility Model Content
