It aims to solve the problem that in prior art, fork truck easily overloads during using, and the service life causing fork truck is shorter, there is peace
The technical problem of full hidden danger.
For achieving the above object, the utility model proposes a kind of fork truck overload restriction system, including three-way body, sensor
Assembly and combined seal ring, described three-way body is provided with three openings, respectively A mouth, B mouth and C mouth, described sensor
Assembly is arranged on three-way body A mouth, and described sensor unit is provided with combined seal ring with the junction of three-way body, described
The B mouth of three-way body, C mouth are connected with in-line, the vent line of hydraulic lifting oil circuit respectively, and described sensor unit also sets up
Having connecting line, described connecting line is connected with controller energising, and described sensor unit is for detecting hydraulic lifting oil circuit
Information, and be converted to signal of telecommunication transmission to controller.
As preferably, the test side of described sensor unit is positioned at the inner chamber of three-way body, and the path with B mouth and C mouth
Intersect.
As preferably, B mouth and the C mouth of described three-way body are located along the same line, and described A mouth is all vertical with B mouth, C mouth
Directly.
As preferably, described sensor unit is for for detecting the oil pressure sensor assembly of hydraulic lifting oil circuit pressure.
As preferably, described sensor unit is for for detecting the temperature sensor assembly of hydraulic lifting oil circuit oil temperature.
The beneficial effects of the utility model: compared with prior art, a kind of fork truck overload that the utility model provides limits
System, rational in infrastructure, realized by three-way body, sensor unit and controller the hydraulic lifting oil circuit of fork truck in real time monitoring and
Control, is monitored and sent detection signal to controller by sensor unit, if the detected value of hydraulic lifting oil circuit is more than regulation
During value, the pumping plant general name being connected with hydraulic lifting oil circuit by controller control quits work, and sensor unit can be oil pressure
Sensor and temperature sensor, prevent overload, prevents because fork truck and other staff are caused by truck driver overload carrying article
Injury, can extend the service life of hydraulic system parts.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
