Description
Technical field
The utility model belongs to car hosit manufacturing technology field, relates to a kind of Hydraulic slewing system in truck crane trouble-shooter.
Background technology
Car hosit is a kind of hoisting crane that is contained on general-utility car chassis or the 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 go everywhere without any hindrance here at all kinds of highways.This kind hoisting crane generally has two control cabins that get on and off, and must stretch out supporting leg during operation and keep stable.The advantage of this hoisting crane is that manoevreability is good, shifts rapidly, is that output is maximum, most popular crane type.
Hydraulic slewing system is to work the most frequently in the system for hydraulic system of truck crane, and one of loop that performance requriements is the highest also is one of the highest loop of car hosit fault occurrence frequency.But existing diagnosis is just keeped in repair reserving operating mode pressure tap pressure measurement and regular dismounting by artificial timing, dependence maintainer's experience is judged the reason of initiating failure, for not having foresight before the fault generation, can not shift to an earlier date ready work, the fault that passive place to go haircut is given birth to.After the et out of order, the practical experience that often will rely on the operator is come the failure judgement point, and the accuracy of trouble diagnosing is lower, so that efficient and the success ratio of maintenance are lower, 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 provides a kind of Hydraulic slewing system in truck crane 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, a kind of Hydraulic slewing system in truck crane trouble-shooter, comprise the PLC controller, the PLC controller is connected with telltale with hydraulic fluid temperature sensor, left rotary motor mouth pressure sensor, right-hand rotation motor mouth pressure sensor, main pump outlet pressure sensor, rotary system back pressure pressure sensor, brake circuit flow sensor, revolution pilot pressure sensor, electric control handle respectively.
The utility model compared with prior art has following advantage: the utility model is by Real-Time Monitoring, analysis to Hydraulic slewing system in truck crane operation parameters state; realize real-time state monitoring and trouble diagnosing to rotary system, thereby can effectively prevent the generation of all kinds of accidents of rotary 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.
