Embodiment Construction

[0019] The method for detecting a dump truck compartment that is difficult to lift, slow to lift, and has movement faults is characterized in that it includes the following steps:

[0020] a) Detect the oil return at the oil return joint of the lift cylinder;

[0021] b) Increase the engine speed and detect the rising speed of the oil cylinder;

[0022] c) After the carriage is lifted for a certain distance, continue to lift to check whether there is movement.

[0023] further:

[0024] The method for detecting the fault of the dump truck compartment that is difficult to lift, slow to lift and has movement, is characterized in that: the step a) includes, if there is no oil return, then enter step b); if there is a lot of oil return, Check the seal of the limit valve of the oil cylinder. If the seal is not tight, use the research limit valve to make it well sealed.

[0025] The method for detecting the fault of the dump truck compartment that is difficult to lift, slow to li...

Abstract

The invention discloses a detection method for lifting difficulty and lifting slowness with a displacement fault of a compartment of a tilting cart. The detection method is characterized by comprising the following steps that (a) oil return at an oil return connector of a lifting oil cylinder is detected; (b) the rotating speed of an engine is increased, and the ascending speed of the oil cylinder is detected; (c) the compartment continues being lifted after being lifted by a certain distance, and whether the displacement fault exists is detected. By executing the detection method for lifting difficulty and lifting slowness with the displacement fault of the compartment of the tilting cart step by step, the fault part can be rapidly judged, the overhaul efficiency can be improved, the matching precision of all components can be guaranteed, and the service life can be prolonged.

Description

technical field [0001] The invention relates to a fault detection method for a dump truck compartment that is difficult to lift, slow to lift and has movement, and belongs to the technical field of engineering machinery. Background technique [0002] The dump truck is a general-purpose equipment in modern construction and production, and the maintenance of each component of the dump truck has matured today with the increasing development of technology. The key to maintenance is to determine the location of the fault. In the past, the equipment that may be related to the fault was often disassembled and inspected one by one. This not only affects the maintenance efficiency, but more importantly, the repeated disassembly of mechanical parts affects its matching accuracy and service life. [0003] If there is a set of detection methods, according to the possible location of the fault and the difficulty of maintenance, it is carried out step by step according to the detection s...
