Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of diesel locomotive overhauling equipment, in particular to a diesel locomotive diesel engine overhauling platform. BACKGROUND

[0002] In the daily overhauling and maintenance work of the diesel locomotive, the diesel engine as one of the core components is of vital importance to the smooth operation of the overhauling work. However, there are many problems in the overhauling process that need to be solved.

[0003] Taking the Dongfeng 7G locomotive as an example, the diesel engine structure is relatively complex and large in size. When the fuel injector and other parts located on the upper part of the diesel engine need to be replaced, the overhauling personnel standing on the locomotive walkway plate cannot smoothly carry out the operation due to the high height of the diesel engine body. In order to complete these operations, the overhauling personnel often have to adopt dangerous postures, such as stepping on the guardrail crossbar with one foot and stepping on the protruding parts on the side of the diesel engine with the other foot to operate. This operation method is not only extremely inconvenient, but also has more oil stains in the diesel engine overhauling site. Once the overhauling personnel slip their feet, it is easy to cause a falling injury accident, which has a great safety hazard and seriously affects the normal progress of the overhauling work and the personal safety of the operating personnel.

[0004] Similarly, when overhauling the air intercooler of the GK1C locomotive diesel engine, many problems are also faced. Due to the lack of a special bracket device, during the disassembly and assembly of the air intercooler, the air intercooler is usually hoisted by a crane, and then four workers manually push the air intercooler to adjust its position in order to complete the disassembly and assembly work. This operation method is not only time-consuming and laborious, but also prone to illegal phenomena such as skewing and slanting during the use of the hoisting rigging, which leads to the damage of the hoisting rigging and low work efficiency. At the same time, since the air intercooler needs to be manually pushed by workers, the overhauling personnel are prone to mechanical injury accidents such as bruising and crushing during the operation process, which has a great safety hazard and seriously affects the smooth progress of the overhauling work and the personal safety of the operating personnel.
