A platform load monitoring device for a hybrid arm insulated boom truck

Abstract

The utility model relates to mixed arm insulating bucket truck load monitoring technical field, concretely is a kind of platform load monitoring device for mixed arm insulating bucket truck. Including turntable and connecting seat, lower arm and pull rod between being arranged in turntable and connecting seat, lower arm oil cylinder is further connected between lower arm and turntable, the connecting seat is equipped with upper arm, upper arm is equipped with telescopic arm, the end of telescopic arm is equipped with work platform, upper arm oil cylinder is equipped between upper arm and connecting seat;Angle sensor is equipped on the lower arm, pressure sensor is equipped on the lower arm oil cylinder. The utility model determines whether platform load is overloaded by detecting lower arm oil cylinder pressure, lower arm amplitude angle, the distribution of pressure sensor and angle sensor avoids insulating area, can directly pass through wire and connect equipment controller to take electricity, need not platform independent power supply, cross-insulation wire, also need not additional battery or hydraulic motor power generation device, both do not destroy insulating property, and also solve the power supply problem of electrical device.
