Description
Technical Field
The utility model relates to the field of auxiliary tools for assembling or maintaining components of an internal combustion locomotive, in particular to a slewing bearing device in a turnover system of a cooling device of the internal combustion locomotive.
Background
The cooling device of the diesel locomotive is an important part of the locomotive and bears the heat load exchange of the diesel engine so as to ensure that the diesel engine works in a proper temperature range. In the practical construction of the internal combustion engine, the cooling device is generally in a V-shaped unbalanced heavy structure, and the internal and external structures are complex. The cooling device has a larger structure compared with the diesel locomotive, and the weight of the single body reaches more than 7 tons. When the cooling device is assembled in the production and manufacturing process or overhauled in the overhaul period, the cooling device is required to rotate 360 degrees in a full working position, and enough operation space is reserved for assembling or testing parts and pipelines. Therefore, the cooling device of the diesel locomotive needs to use the arranged cooling device overturning system during production or overhaul, so that the cooling device can rotate 360 degrees on the overturning system, and the requirement of assembly production or overhaul of the cooling device is met.
At present, a common turnover system of a cooling device generally comprises an electric drive device (power end) fixedly arranged on one side of the cooling device and fixedly connected with the cooling device and a slewing bearing device (non-power end) fixedly arranged on the other side of the cooling device and fixedly connected with the cooling device, wherein the electric drive device and the slewing bearing device which are respectively arranged on two sides of the cooling device are respectively fixedly arranged, and the distance between the electric drive device and the slewing bearing device is unchanged, so that one set of turnover system can only be applied to the cooling device of a certain corresponding model, and the turnover system has the advantages of convenience in installation and obvious defects: because there are many locomotive models (such as DF series diesel locomotive for freight main line), the size difference of the cooling device structure of the locomotive of different models is very different, in order to adapt to the production or maintenance of the cooling device of different sizes, a set of turning system needs to be arranged for each size of cooling device, and the equipment cost and the floor occupation cost of the factory building are high. In order to solve the problem, the currently adopted improved technical scheme is as follows: the distance between the fixedly arranged electric driving device and the slewing bearing device is set according to the cooling device suitable for the largest size, when the slewing bearing device is used for the cooling device with the smaller size, the distance between the power end and the non-power end is shortened by additionally arranging the connecting transition block on the slewing bearing device so as to adapt to the cooling devices with different models and sizes, and the problem exists that: the connection transition blocks need to be additionally provided with a hoisting machine for lengthening operation (a cooling device also needs a large hoisting machine), labor and time are wasted, and the installation space position of the connection transition blocks adopting bolts is insufficient, so that the installation is very inconvenient, and therefore, the improvement has no practical production significance. Therefore, how to improve the slewing bearing device in the turnover system of the existing cooling device to effectively solve the technical problem that the turnover system of the existing cooling device can only be applied to the cooling devices with a certain size but not to the cooling devices with all sizes, which needs to be solved urgently in the industry.
