A car crane that uses the cooling water of the off-car engine to heat the lifting control room

Abstract

The invention relates to an autocrane heating a lifting control room by utilizing cooling water of a lower-vehicle engine. A revolution water feeder (3) is disposed between a lower vehicle (1) and an upper vehicle (2) and includes a fixed body (31) and a revolution body (32) which are in rotation matching. A first annular water path (33) and a second annular water path (34) are disposed between the fixed body (31) and the revolution body (32). The fixed body (31) is provided with a first pipe joint (35) and a second pipe joint (36) which are separately in series connection in a cooling water circulating pipeline of an engine (13). A heat dissipation finned radiator (23) is disposed in the lifting control room (22). The revolution body (32) is provided with a third pipe joint (37) and a fourth pipe joint (38) respectively communicating with the heat dissipation finned radiator (23). The cooling water of the lower-vehicle engine is utilized to heat the lifting control room of the upper vehicle, and therefore consumption of a large amount of fuel for heating lifting control rooms of autocranes having medium and small sizes in winter is not required, the running cost of the autocrane in winter in reduced, and energy conservation and emission reduction are facilitated.

Description

technical field [0001] The invention relates to a truck crane, in particular to a truck crane which utilizes engine cooling water to heat a lifting control room. Background technique [0002] The car crane is a kind of crane that is equipped with a boom on an ordinary car chassis or a special car chassis. The driving room of this crane is set separately from the lifting control room. The booms are set together on the upper carriage. The temperature in winter in the northern region is relatively low, and both the driving compartment and the lifting control room need heating. Since the driving compartment is located on the alighting vehicle, it can conveniently use the waste heat of the engine for heating. The large-tonnage truck crane is equipped with an engine on the board, so the waste heat from the engine can be used to heat the hoisting control room. However, there is no engine on the board of the small and medium-sized truck crane. Currently, fuel oil can only be used f...
