Abstract

The invention discloses a novel diesel engine monorail crane hydraulic system which comprises a main hydraulic pump, a main hydraulic pump high-pressure overflowing valve, a main hydraulic pump DA valve, a high-pressure filter, a first one-way valve, a gear pump, an air filter, a hydraulic oil tank, a second one-way valve, an oil return filter, a first overflowing valve, a first quick-change connector, a third one-way valve and a manual pump. The novel diesel engine monorail crane hydraulic system has the advantages of high security, high control precision, simplicity and convenience in operation and high reliability; due to adoption of a closed hydraulic system, the outlet of the main hydraulic pump is directly connected with travel motors, the travel motors are connected together in parallel and can be correspondingly increased or reduced in the connection manner according to practical use situation; the outlet of the main hydraulic pump extends into a hydraulic oil radiator through an oil return pipeline; in order to meet requirements of a trailer, a manual valve is configured, and the manual valve is directly connected with the oil inlet / outlet of the main pump; a walking loop further has a driving rejection function, that is, four hydraulic motors can be simultaneously off loaded to increase the operation speed of a locomotive.

Description

technical field [0001] The invention relates to a hydraulic system, in particular to a novel diesel engine monorail crane hydraulic system, which belongs to the technical field of hydraulic applications. Background technique [0002] Diesel engine monorail track auxiliary transportation system is a type of coal mine auxiliary operation system, including diesel engine monorail locomotive, lifting beam, specially designed rail track and related hanging parts. Diesel engine monorail locomotives use diesel engines as power sources, run on specially designed steel rails, and transport personnel and materials through special lifting beams. The existing diesel monorail crane hydraulic system generally suffers from the disadvantages of poor system reliability, low traction force, large safety hazard, unstable operation and low efficiency. Therefore, a new diesel monorail crane hydraulic system is proposed to solve the above problems. Contents of the invention [0003] The object...
