Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Autospasy rope type cargo hook gear of the present invention, comprise two circular suspension hooks 2, the head 21 that suspension hook 2 comprises hook part 22 and is connected in hook part 22, hook part 22 radian is identical, suspension hook 2 utilizes crab-bolt to be fixed on by head 21 on U-shaped bracing frame 1, and suspension hook 2 and bracing frame 1 are hinged relationship.Two crab-bolts, namely jointed shafts, both parallel a be separated by segment distance and axis, and the opening of two hook part 22 is relative.As shown in Fig. 1, Fig. 6.
Wherein bracing frame 1 is main supporting part, and need casting, its structure as shown in Figure 4.
As shown in Figure 3, Figure 4, head 21 outline of suspension hook comprises circular arc transmission segment 23, the arc center of circle of transmission segment 23 is dropped on jointed shaft axle center, transmission segment 23 surface working has teeth, be equivalent to one section of gear do not closed, suspension rod 4 is similar to rack pinion to the motion matching relationship of gear, and just stroke is shorter.Suspension rod 4 moves up and down freely through bracing frame 1, drives head 21 to rotate centered by jointed shaft.The head 21 of suspension rod 4 and left and right two suspension hooks 2 is all meshed, two suspension hook 2 synchronous axial system, opening the moving up and down and folding along with suspension rod 4 of hook part 22.
Head 21 outline also comprises platform section 24, a lift block 41 is comprised bottom suspension rod 4, move up two hook part 22 that turn to of drive two suspension hooks 2 of suspension rod 4 coincide under state, the platform section 24 of two heads 21 is positioned at a plane and perpendicular to suspension rod 4 axis, lift block 41 bracketing of suspension rod 4 is below platform section 24; Suspension rod 4 upper end is lifting hole(eyelet), and under this state, two hook part 22 hook group hoisting ropes, can carry out lifting operation.Hoisting rope is subject to the lift of two suspension hooks 2, and simultaneously two hook part 22 surround a closed circular arc, lift safer.
The conveniently automatic open and close of suspension hook 2, bracing frame 1 upper head plate 12 is provided with at least two springs 6, and the upper end of spring 6 is hooked in connecting panel 5, and connecting panel 5 is connected with suspension rod 4, and two hook part 22 coincide under state, and spring 6 is maximum by pulling force; Suspension rod 4 moves down, and when two relative opening angles of hook part 22 are maximum, spring 6 is minimum by pulling force.
Use operating process is as follows:
Hoisting rope is hung on suspension hook 2 when needs lift, along with steel rope pulling force upwards, suspension rod 4 is also along with pulling, at this moment the cooperation of operating personal is needed, suspension rod 4 is made to drive two suspension hooks 2 to rotate, after the hook part 22 of two suspension hooks is closed, owing to hanging thing Action of Gravity Field, the flush configuration of the lift block 41 of suspension rod 4 lower end can be mutually stuck with the platform section 24 of two suspension hooks 2, prevents two suspension hooks 2 from loosening.At the end of lifting operation, looseness of steel wire ropes, spring 6 pulls suspension rod 4 to move downward, and drive suspension ring 42 to open, rope comes off.Refer to the closed and suspension hook 2 of drawing suspension hook 2 and open figure.
In order to be that the hook part 22 of two suspension hooks is fitted more firmly, both are semicircle by cross-sectional plane, and relative binding face adopts the concavo-convex tenon structure of band, and this structure also increases the intensity of suspension hook 2.As shown in Figure 2.
Cargo hook gear of the present invention is only applicable to the lifting operation within 5 tons.
