Abstract

The invention discloses an emergency control system and a crane. The emergency control system comprises an emergency power module and an emergency control module. A main system control oil way, an auxiliary system control oil way, a supporting leg system control oil way, a rotary system control oil way and a pilot system control oil way are included in the emergency control module. The emergency power module comprises a power device, an emergency main pump, an emergency pilot pump, a first reversing valve and a second reversing valve. The power device is connected with the emergency main pumpand the emergency pilot pump. The emergency power module and the emergency control module are connected through a detachable first connector and a detachable second connector. After passing through the first reversing valve and the first connector, the emergency main pump is connected with the main system control oil way, the auxiliary system control oil way, the supporting leg system control oilway and the rotary system control oil way in the emergency control module. After passing through the second reversing valve and the reversing connector, the emergency pilot pump is connected with thepilot system control oil way in the emergency control module.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, in particular to an emergency control system and a crane. Background technique [0002] For single-engine truck cranes or all-terrain cranes, when the engine or gearbox fails to work, the crane loses its power source, and each action can no longer be controlled. position, if the environment changes, such as the wind speed increases, the crane will be in a dangerous state, and may even cause overturning, resulting in serious losses. The main subsystems such as slewing, winch, and jib return to a safe state. In order to be able to be pulled by the tractor, the outriggers need to be recovered. In order to meet the requirements of the on-road axle load regulations, the counterweight oil circuit must be controlled at the same time to realize counterweight unloading. , the emergency control device usually does not have high requirements on the operation time, but requires easy and fast i...
