Description
Technical field
The utility model belongs to car hosit manufacturing technology field, relates to a kind of car hosit variable amplitude hydraulic system trouble-shooter.
Background technology
Car hosit is a kind of hoisting crane that is contained on general-utility car chassis or cars chassis.The chassis performance of car hosit is equal to the autotruck of same car load gross weight, meets the technical requirements of road vehicle, thereby can on all kinds of highways, go everywhere without any hindrance here.This kind hoisting crane generally has two control cabins that get on and off, and during operation, must stretch out supporting leg and keep stable.The advantage of this hoisting crane is that manoevreability is good, shifts rapidly, and be the output maximum, most popular crane type.
Variable amplitude hydraulic system is in system for hydraulic system of truck crane, to work more frequently, and one of loop that performance requriements is higher, be also one of loop that the car hosit fault occurrence frequency is higher.But existing diagnosis is just keeped in repair reserved operating mode pressure tap pressure measurement and regular dismounting by artificial timing, dependence maintainer's experience judges the reason of initiating failure, before for fault, occurring, there is no foresight, can not shift to an earlier date ready work, the fault that passive place to go haircut is given birth to.After et out of order, the practical experience that often will rely on the operator is carried out the failure judgement point, and the accuracy of trouble diagnosing is lower, makes the efficiency of maintenance and success ratio lower, and this has caused very large difficulty for solving fast, timely fault.Simultaneously, increase operator's labour intensity, reduced operating efficiency, caused cost increase and mechanical efficiency reduction etc.
The utility model content
The purpose of this utility model is to provide a kind of car hosit variable amplitude hydraulic system trouble-shooter, the technical matters that maintenance difficult, maintenance efficiency are low, maintenance cost is high that exists to overcome prior art.
the technical scheme that the utility model adopts is, comprise the PLC controller, the PLC controller respectively with the hydraulic fluid temperature sensor, amplitude oil cylinder rises the mouth pressure sensor, the mouth pressure sensor falls in amplitude oil cylinder, the main pump outlet pressure sensor, luffing balance cock control mouth pressure sensor, luffing pilot pressure sensor, telltale, buzzer phone is connected with electric control handle, amplitude oil cylinder rises the mouth pressure sensor, the mouth pressure sensor falls in amplitude oil cylinder, the main pump outlet pressure sensor, luffing balance cock control mouth pressure sensor and luffing pilot pressure sensor are arranged on respectively the car hosit amplitude oil cylinder and rise mouth, mouth falls in amplitude oil cylinder, main pump outlet, luffing balance cock control mouth and multiway valve luffing guide are controlled on mouth.
The utility model compared with prior art has following advantage: the utility model is by Real-Time Monitoring, analysis to car hosit variable amplitude hydraulic system operation parameters state; realize real-time state monitoring and trouble diagnosing to changing-breadth system, thereby can effectively prevent the generation of all kinds of accidents in luffing loop and the economic loss that hang-up brings.The information such as relevant fault cause, fault happening part are provided for service personnel; early detection, maintenance, maintenance and reparation to the car hosit fault provide technical support; improve the service life of car hosit; shortened maintenance time; improve maintenance efficiency, reduced maintenance cost, reduced outage rate; improved operating efficiency, economic benefit is very remarkable.
