Abstract
A fault detection method for the phenomenon that the self-lifting position of a tilting cart carriage cannot be laid down is characterized by comprising the following steps that (a) a hydraulic distribution valve sliding rod is detected; (b) a hydraulic distribution valve piston rod is detected; (c) a kinematic pair of a lifting tilting mechanism is detected; (d) the lifting angle is detected. The detecting steps are executed step by step, the fault position can be judged quickly so that the overhauling efficiency can be improved, the matching precision of all parts can be guaranteed, and the service life is prolonged.
Description
Technical field
The present invention relates to tip lorry compartment and can not put down fault detection method from lift location, belong to technical field of engineering machinery.
Background technology
Tip lorry is Modern Construction and the common apparatus in production, and the maintenance of each constituent elements of tip lorry is ripe in today that technology is growing.The key of maintenance judges trouble location, took equipment that may be relevant with fault often apart in the past, and checked one by one during maintenance.This not only have impact on overhaul efficiency, the more important thing is, the dismounting repeatedly of mechanical part, affects its quality of fit and tenure of use.
If there is a set of method of inspection, the possible position occurred according to fault and the difficulty or ease of maintenance, progressively carry out by detecting step, if certain step eliminates fault, then need not carry out the maintenance of following steps, not only can judge trouble location fast, improve overhaul efficiency, and the quality of fit of each parts can be ensured, improve tenure of use.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide tip lorry compartment and can not put down fault detection method from lift location, progressively carry out by this invention detecting step, not only can judge trouble location fast, improve overhaul efficiency, and the quality of fit of each parts can be ensured, improve tenure of use.
For achieving the above object, the present invention is realized by following technological means:
Tip lorry compartment can not put down fault detection method from lift location, it is characterized in that: comprise the following steps:
A) hydraulic distributing valve slide bar is detected;
B) hydraulic distributing valve piston rod is detected;
C) kinematic pair of lifting tilting mechanism is detected;
D) lifting angle is detected.
Further:
Described tip lorry compartment can not put down fault detection method from lift location, it is characterized in that: described step a) comprises, and as hydraulic distributing valve slide bar puts in place, then enters step b); As hydraulic distributing valve slide bar is dialled not in place, replied and put in place.
Described tip lorry compartment can not put down fault detection method from lift location, it is characterized in that: described step b) comprise, as bending does not appear in hydraulic distributing valve piston rod, then enter step c); As hydraulic distributing valve piston rod occurs bending, repair or change.
Described tip lorry compartment can not put down fault detection method from lift location, it is characterized in that: described step b) comprise, as distortion does not appear in hydraulic distributing valve piston rod, then enter step c); As distortion appears in hydraulic distributing valve piston rod, repair or change.
Described tip lorry compartment can not put down fault detection method from lift location, it is characterized in that: described step c) comprise, the kinematic pair as lifting tilting mechanism does not pollute, then enter steps d); Kinematic pair as lifting tilting mechanism pollutes, and is cleaned.
Described tip lorry compartment can not put down fault detection method from lift location, it is characterized in that: described steps d) comprise, as lifting angle does not exceed design maximum lifting angles degree, then detection of end; As lifting angle exceedes design maximum lifting angles degree, there is mechanism dead point, then loosen hydraulic distributing valve tube head, abolish clamping stagnation.
The invention has the beneficial effects as follows: progressively carry out by this invention detecting step, not only can judge trouble location fast, improve overhaul efficiency, and the quality of fit of each parts can be ensured, improve tenure of use.
