Description

Technical Field

[0001] The invention relates to the technical field of building 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, mainly for transporting construction items on high floors in conjunction with cranes. Currently, unloading platforms on the market will indicate the maximum load capacity to avoid construction safety accidents caused by overloading. However, in actual use, construction workers often find it difficult to judge the actual weight of the construction items to be transported, so there are safety hazards when using unloading platforms. For this reason, the market has launched an unloading platform with an overweight alarm system, such as the unloading platform with an overweight alarm system disclosed in patent number 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 of front wheels and rear wheels, so that the unloading platform can slide and retract forward and backward on the chassis; when the unloading platform slides outward to the working state, 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 has a small amount of modification to the existing unloading platform and can be well used for modification and processing of the existing unloading platform, the torque change between 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, so that the error range of the pressure effect of the rear wheel on the pressure sensor is large, 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. Summary of the invention
