Description
Technical field
The present invention relates to diesel engine of diesel locomotive cylinder head upkeep operation automatic turning device.
Background technology
Cylinder head is the connecting element of diesel engine and the component part of combustion chamber, and fuel injector, rocker shaft bed indicator valve and inlet and outlet valve etc. are installed on cylinder head, and there are intake and exhaust port and cooling water cavity in cylinder head inside, and its complex structure, duct are more, wall unevenness.The service conditions of cylinder head is extremely severe, and the head combustion chamber face directly contacts with high temperature, high-pressure gas, bears mechanical load and thermal load, the exhaust gas corrosion of higher cycle variation and washes away, and produces very large mechanical strees and thermal stress.The cylinder head stud predetermincd tension makes cylinder head be subject to compression effort, also can produce stress at cylinder head changes of section place and concentrate.
Therefore cylinder head is easier to occur damaging, and its damage type mainly contains the crackle on bottom surface and cold side surface, the burn into air valve seat surface on cold side surface and the wearing and tearing of guide pin bushing etc.
During the current upkeep operation to cylinder head, cylinder head need to be overturn, with combustion chamber face, end face or side to cylinder head, overhauled or detect a flaw.Current method of operation, be all that because cylinder head weight is larger, check man's process flow need to overturn several times by the artificial manual overturning of part, so switching process need to expend a lot of manpower and materials, to service work, makes troubles, and wastes time and energy again.And at present turning rack can't be realized multiple work compound requirement, can a plurality of cylinder heads of once inside out, improve the efficiency of service work.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art, after mainly overturning with clamping mode or clamped position etc., to the flaw detection of combustion chamber face, provide a kind of cylinder head upkeep operation automatic turning device.
For achieving the above object, the present invention adopts following technical proposals:
A kind of cylinder head upkeep operation automatic turning device, it comprises support carriers, at least one switching mechanism, described switching mechanism comprises turnover bracket, the two ends of turnover bracket are arranged on support carriers by axle, wherein the axle of a side also is connected with worm-gear speed reducer, and worm-gear speed reducer is connected and is connected with control box with motor; Described turnover bracket is provided with at least one cylinder head fixed part, and described cylinder head fixed part comprises a plurality of for the standing screw through cylinder bolt hole and the nut that cylinder head to be installed is fixed; The below of described cylinder head fixed part is provided with the valve fixed part, described valve fixed part comprises the locating support of being located at cylinder head fixed part below, passed an elevating screw by screw thread on locating support, the upper end of elevating screw connects and is used for the fixedly supporting plate of valve, and lower end is provided with handwheel.
