Problems solved by technology

The current operation method is to turn over manually by some people. Due to the heavy weight of the cylinder head, the maintenance process needs to be turned over several times, so the turning process needs a lot of manpower and material resources, which brings inconvenience to the maintenance work and is time-consuming and laborious.
Moreover, the current flip frame cannot meet the requirements of multiple joint operations, and can flip multiple cylinder heads at one time to improve the efficiency of maintenance work

Abstract

The invention discloses an automatic overturning device for maintenance operation of a cylinder cover, which comprises a supporting base and at least one overturning mechanism. The overturning mechanism comprises an overturning support, two ends of the overturning support are installed on the supporting base through shafts, and the shaft on one side is connected with a worm gear reducer, a motor and a control box. At least one cylinder cover fixing portion is arranged on the overturning support, the cylinder cover fixing portion comprises a plurality of fixed screws and nuts, a valve fixing portion is arranged below the cylinder cover fixing portion, the valve fixing portion comprises a positioning support arranged below the cylinder cover fixing portion, a lifting lead screw penetrates through the positioning support through threads, the upper end of the lifting lead screw is connected with a supporting plate for fixing a valve, and a hand wheel is arranged at the lower end of the lifting lead screw. The automatic overturning device for the maintenance operation of the cylinder cover achieves overturning of a cylinder cover and fixation of the valve, reduces labor intensity, meets maintenance requirements, can overturn a plurality of cylinder covers, and improves working efficiency.

Description

technical field [0001] The invention relates to an automatic overturning device for diesel engine cylinder heads of diesel locomotives. Background technique [0002] The cylinder head is the fixed part of the diesel engine and a part of the combustion chamber. The fuel injector, the rocker shaft seat indicator valve, the intake and exhaust valves, etc. are installed on the cylinder head. There are intake and exhaust passages and cooling water inside the cylinder head. The cavity has a complex structure, many channels, and uneven wall thickness. The working conditions of the cylinder head are extremely harsh. The combustion chamber surface of the cylinder head is directly in contact with high-temperature and high-pressure gas, and bears high periodic mechanical and thermal loads, gas corrosion and erosion, resulting in great mechanical and thermal stress. The pre-tightening force of the cylinder head bolts causes the cylinder head to be subjected to compressive stress, and s...
