The invention provides a small-load freight elevator weighing type outbound system which comprises a simulation finger arranged in a foundation pit preset in front of an elevator door, a pressure-bearing steel plate arranged on a top opening of the foundation pit and a compression spring arranged in the foundation pit and used for supporting the pressure-bearing steel plate, and the simulation finger is connected with an instruction board of an elevator outbound box in parallel through a wire. The simulation finger is used for generating an elevator calling door opening instruction when sensing that the pressure-bearing steel plate is pressed down by an upper heavy object; in a normal state, the simulated finger has a preset distance from the pressure-bearing steel plate. According to the weighing type outbound system of the small-load freight elevator, when front wheels of a forklift loaded with goods are pressed on the pressure-bearing steel plate, the pressure-bearing steel plate moves downwards through the compression spring, when the simulated finger senses that the downward moving distance of the pressure-bearing steel plate reaches the preset distance, the elevator calling door opening instruction is automatically generated, a worker does not need to open a goods elevator door manually, time and labor are saved, and the working efficiency is improved. The use is convenient.
本发明提供的一种小载重载货电梯称重式外呼系统,包括设置于电梯门前预设的基坑中的模拟手指、设置于基坑顶口上的承压钢板、设置于基坑内的用于支撑承压钢板的压缩弹簧,模拟手指通过导线与电梯外呼盒的指令板并联,该模拟手指用于在感测到承压钢板受到上方重物下压的力时,生成呼梯开门指令;常态下,模拟手指距离承压钢板预设距离。本发明提供的小载重载货电梯称重式外呼系统,装载有货物的叉车前轮压在承压钢板上时,承压钢板通过压缩弹簧下移,在模拟手指感测到承压钢板下移的距离达到预设距离时,自动生成呼梯开门指令,无需人员手动开货梯门,省时省力,使用便利。
