Detailed Implementation Methods

[0018] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0019] See appendix Figs. 1-3This application provides a unloading platform with an overload alarm system, including a base frame 1 and an unloading platform 2. Rolling mechanisms are provided on both sides of the unloading platform 2, allowing it to slide along the base frame 1. The rolling mechanisms include a front wheel 3 and a rear wheel 4. The front wheel is located near the middle of the unloading platform, while the rear wheel is located near the rear of the platform. The base frame 1 has wheel cavities for the front wheel 3 and rear wheel 4 to roll. Specifically, the base frame includes two parallel H-channel steels spaced apart, with the inner groove of the H-channel steel serving as the wheel cavity. The unloading platform also includes an alarm 5 and a pressure sensor 6. 6 is used to trigger the alarm 5 to issue an alarm. The pressure sensor 6 is set on the base frame 1. The trigger part 61 of the pressure sensor 6 extends into the wheel cavity and can be triggered by the rear wheel 4. Specifically, when the unloading platform slides outward and the boom places the building material on the unloading platform, the front end of the unloading platform is downward under the action of gravity. At this time, the front wheel acts as a fulcrum, while the rear wheel tilts upward. The tilting rear wheel applies pressure to the pressure sensor. The heavier the building material placed on the unloading platform, the greater the pressure applied by the rear wheel to the pressure sensor. When the pressure value reaches the preset value of the pressure sensor, the alarm will immediately issue an alarm reminder.

[0020] The front end of the wheel cavity is provided with a stop 7, which can prevent the front wheel 3 from moving forward, thus preventing the unloading platform from extending excessively and preventing the unloading platform from detaching. When the front wheel 3 contacts the stop 7, the rear wheel 4 corresponds to and triggers the trigger 61. When the front wheel contacts the stop, it is the maximum extension length of the unloading platform. At this time, the trigger 61 of the rear wheel can ensure that pressure can be applied to the trigger 61 immediately after the building material is placed on the unloading platform.

[0021] The pressure sensor 6 consists of two sensors, which are symmetrically arranged on both sides of the base frame 1. The two pressure sensors work together to more accurately identify the weight of the building materials on the unloading platform, so as to issue alarms more accurately.

[0022] The pressure sensor 6 is located on the upper side of the wheel cavity. The base frame 1 has a hole for the trigger part 61 to extend into the wheel cavity. A control box 8 is mounted on the base frame 1, and the control box 8 is electrically connected to the alarm 5 and the pressure sensor 6. The control box 8 has a power supply, specifically a battery, which is connected to a charging interface for charging. Therefore, the alarm can operate without an external power source when the battery has sufficient charge. The alarm 5 is a speaker and / or an alarm light. The alarm 5 is mounted and fixed on the base frame 1. The speaker emits a continuous alarm sound, and the alarm light flashes.

[0023] The pressure sensor 6 is mounted on the base frame 1 via the mounting base 9. The mounting base 9 is provided with adjusting bolts to adjust the position of the pressure sensor 6 so as to change the triggered position of the trigger part 61. In this way, the pressure trigger positions of the pressure sensors on both sides of the base frame can be adjusted to make them uniform.

[0024] The upper surface of the unloading platform 2 is provided with a cargo marking area 10, which is surrounded by stickers or spray paint.

[0025] The base frame 1 is provided with a support rod 11. The bottom end of the support rod 11 is connected and fixed to the base frame 1. The top of the support rod 11 is provided with a telescopic rod 12. The telescopic rod is used to hold the roof to ensure the stability of the tail of the base frame.

[0026] The above description is only a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present invention should be included within the scope of protection set forth in the claims.
