Wheel-rail traction system of trailing suction hopper dredger

Abstract

The invention discloses a wheel-rail traction system of a trailing suction hopper dredger, and relates to the technical field of engineering machinery, in particular to the wheel-rail traction systemof the trailing suction hopper dredger. The wheel-rail traction system of the trailing suction hopper dredger involves a trolley, a tractor, a winch and a winding drum device, wherein one side of thetrolley is connected with the tractor through a bolt, the winch is arranged at the top end of the tractor, and the winding drum device is arranged in the middle of one side of the winch. According tothe wheel-rail traction system of the trailing suction hopper dredger, the tractor is used for driving the trolley through the winch, so that the trolley can still be driven when the driving force ofthe trolley is closed, and the trolley does not slip during heavy-load starting; and the middle part of the winding drum device can be tensioned outwards, the stress on a steel wire is more uniform, the attaching force between the steel wire and the outer side of the winding drum device is stronger, so that the phenomenon that a steel wire rope slips when the winding drum device rotates is avoided, the extending length of the steel wire rope under stress is effectively reduced, and the traction precision of the tractor acting on the trolley and the traction stability of the tractor are effectively improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a wheel-rail traction system of a trailing suction dredger. Background technique [0002] The trailing suction dredger is equipment for dredging and reclamation operations. Its main construction part is the suction trolley. The traction force that can be provided is small, so that the moving speed of the suction trolley is slow, and when the suction trolley is driven by its own power, it cannot be driven by itself when the load of the suction trolley itself is large, and it is easy to cause damage to the drive motor; In addition, the driving wheel of the suction trolley tends to slip during the initial stage, which makes the instantaneous traction force of the suction trolley low and cannot drive the trolley to move, which affects the stability of the traction force output when the trolley is self-driven.
