The invention relates to the technical field of detection equipment, and provides a no-load elevator overload switch detection device based on hydraulic drive. The device comprises an acting plate, a hydraulic clamping mechanism and a pressure sensor, the acting plate comprises a supporting plate and a stress plate, an overload switch is arranged between the supporting plate and the stress plate, two ends of the overload switch are respectively in contact with the supporting plate and the stress plate, the hydraulic clamping mechanism can enable the stress plate to move towards the supporting plate, the pressure sensor is arranged between the hydraulic clamping mechanism and the stress plate, and the pressure sensor is used for detecting the force applied by the hydraulic clamping mechanism to the stress plate. According to the device, the problems that weights need to be carried during inspection of elevator overload switches, and time and labor are wasted are solved; a overload switch tester is connected through a screw rod so that the weight of the device is reduced to the maximum while the supporting force is ensured; and during testing, an operator is located outside a hoistway and obtains a pressure value by operating a manual pump and a signal acquisition circuit so that the operation of the operator is more convenient.

    本发明涉及检测设备技术领域,提供一种基于液压驱动的无载电梯超载开关检测装置,包括:作用板,作用板包括支撑板和受力板,超载开关设置于支撑板和受力板之间,超载开关的两端分别与支撑板和受力板相接触;液压夹紧机构,液压夹紧机构能够使受力板向支撑板移动;压力传感器,液压夹紧机构与受力板之间设有压力传感器,压力传感器用于检测液压夹紧机构对受力板施加的力,本发明解决电梯超载开关检验需搬运砝码、费时费力的问题;超载开关测试仪利用丝杆连接,保证支撑力的同时最大限度的减轻了设备的重量;测试时,操作人员位于井道外,通过操作手动泵和信号采集电路获取施压力值,使得工作人员操作更加方便。
