Description
Technical field
The utility model belongs to car hosit manufacturing technology field, relates to a kind of car hosit Failure Diagnosis of Hydraulic System device that hoists.
Background technology
Car hosit is a kind of hoisting crane being 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 of hoisting crane generally has two control cabins that get on and off, and must stretch out supporting leg and keep stable during operation.The advantage of this hoisting crane is that manoevreability is good, shifts rapidly, is that output is maximum, most popular crane type.
The hydraulic efficiency pressure system that hoists is in system for hydraulic system of truck crane, to work the most frequently, and one of loop that performance requriements is the highest, is also one of loop that car hosit fault occurrence frequency is the highest.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 occurring for fault, there is no foresight, can not shift to an earlier date ready work, the passive raw fault of place to go haircut.After et out of order, the practical experience that often will rely on operator is carried out failure judgement point, and the accuracy of trouble diagnosing is lower, makes efficiency and the success ratio of maintenance lower, and this has caused very large difficulty for solving fast, timely fault.Meanwhile, increase operator's labour intensity, reduced operating efficiency, caused cost increase and mechanical efficiency reduction etc.
Utility model content
The purpose of this utility model is to provide a kind of car hosit Failure Diagnosis of Hydraulic System device that hoists, the technical matters that maintenance difficult, maintenance efficiency are low, maintenance cost is high existing to overcome prior art.
The technical scheme that the utility model adopts is, a kind of car hosit Failure Diagnosis of Hydraulic System device that hoists, comprise PLC controller, PLC controller rises mouth pressure sensor, hoist motor with hydraulic fluid temperature sensor, hoist motor respectively and falls mouth pressure sensor, main pump outlet pressure sensor, hoist motor balance cock control mouth pressure sensor, brake circuit flow sensor, hoist pilot pressure sensor, electric control handle and telltale and be connected.
The utility model compared with prior art tool has the following advantages: the utility model is by Real-Time Monitoring, the analysis of each operation parameters state of hydraulic efficiency pressure system that car hosit is hoisted; realized the real-time state monitoring of hoisting system and trouble diagnosing, thereby can effectively prevent the generation of all kinds of accidents of hoisting circuit and the economic loss that hang-up brings.The information such as relevant fault cause, fault happening part are provided for service personnel; to the early detection of car hosit fault, maintenance, maintenance and reparation, 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
With reference to Fig. 1, the car hosit of the present utility model Failure Diagnosis of Hydraulic System device that hoists,
