Embodiment
For further understanding technology contents of the present invention, characteristics and effect, enumerate following example now, and conjunction with figs. is described in detail as follows:
With reference to accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 and Figure 10.
Embodiment
A kind of hanger rope pivot angle detection device of drag arm of trailing suction dredge is by the gravity servo-actuated hanging scaffold 1 that can safeguard, stainless steel chain sling 2, hanging scaffold arbitrary-movement articulator 3, angular transducer watertight box 4, bearing cap 5, watertight box fixed orifice 6, chain sling connecting hole 7, hanging scaffold abutment ring 8, abutment ring fixed orifice 9; Balance staff 10, balance staff nut 11, balance staff support compositions such as backing plate 12.The gravity servo-actuated hanging scaffold 1 that can safeguard, stainless steel chain sling 2, hanging scaffold arbitrary-movement articulator 3, angular transducer watertight box 4, balance staff 10 are critical components of the present invention.The vertical gravity servo-actuated hanging scaffold that can safeguard is that the disk that length is slotted is formed by two with the semicircle, the interior circular diameter of disk is greater than rake arm hanger rope diameter (interior circular diameter is greater than rake arm hanger rope diameter 4mm), material is a stainless steel, the disk slotted section of two flutings is overlapping relatively up and down, adopts screw to fix.The disk upper end is provided with the hanger rope abutment ring of 4 special uses, and the hanger rope abutment ring adopts snap ring to be connected with chain sling.Adopt the stainless steel chain sling to connect with snap ring between gravity servo-actuated hanging scaffold, the swing arm, the swing arm other end adopts nut to be fixed on the balance staff, inlays sealing bearing on the balance staff.Balance staff is connected with the balance staff backing plate, and the balance staff welding with backing is connected on the rake arm hanger rope pulley support frame of rake arm A word support 16 tops 14, and balance staff center and steel wire hanger rope pulley 13 external diameters (deducting the wire rope radius) are tangent.Fixed angle sensor watertight box (angular transducer is installed in the seal box) in the swing arm.
Rake arm hanger rope pivot angle detects the hunting gear working condition: because the interior circle of the axle center of balance staff 8 and hanger rope pulley 13 is tangent to mid point between the cylindrical (being the wirerope intermediate point), when rake arm 17 is subjected under water soil property, current and when producing displacement, rake arm hanger rope 15 produces displacement, drive rake arm hanger rope pivot angle and detect the hunting gear displacement, be installed in rake arm hanger rope pivot angle and detect obliquity sensor watertight box 4 displacements thereupon of hunting gear, thereby detect the 17 vertical angle displacements of rake arm.Angular transducer is installed in more than the deck, has solved the watertight problem well, has improved sensor serviceable life, has increased the reliability height of rake arm display device.
