The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Autospasy rope formula cargo hook gear of the present utility model, comprise two circular suspension hooks 2, suspension hook 2 comprises crotch portion 22 and is connected to the head 21 in crotch portion 22, and crotch portion 22 radians are identical, suspension hook 2 utilizes crab-bolt that head 21 is fixed on U-shaped bracing frame 1, and suspension hook 2 is hinged relationship with bracing frame 1.Two crab-bolts, jointed shaft namely, both parallel a be separated by segment distance and axis, and the opening of two crotch portions 22 is relative.As shown in Fig. 1, Fig. 6.
Wherein bracing frame 1 is main supporting part, needs casting, and its structure as shown in Figure 4.
As shown in Figure 3, Figure 4, head 21 outlines of suspension hook comprise circular arc transmission section 23, the arc center of circle of transmission section 23 is dropped on jointed shaft axle center, transmission section 23 surface working have teeth, be equivalent to one section of gear not sealing, suspension rod 4 is similar to rack-and-gear transmission 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 two suspension hooks 2 of suspension rod 4 and left and right is all meshed, and two suspension hooks 2 synchronously rotate, and the opening of crotch portion 22 is along with suspension rod 4 moves up and down and folding.
Head 21 outlines also comprise platform section 24, suspension rod 4 bottoms comprise that lifts a piece 41, suspension rod 4 moves up and drives two the crotch portions 22 that turn to of two suspension hooks 2 to coincide under state, the platform section 24 of two heads 21 is positioned at a plane and perpendicular to suspension rod 4 axis, suspension rod 4 lift piece 41 bracketings below platform section 24; Suspension rod 4 upper ends are lifting hole(eyelet), and under this state, two crotch portion 22 hook group hoisting ropes, can carry out lifting operation.Hoisting rope is subject to lifting of two suspension hooks 2, and the while, two crotch portions 22 surrounded the circular arc of a sealing, lifted safer.
In order to facilitate the 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 crotch portions 22 coincide under state, and spring 6 is subject to pulling force maximum; Suspension rod 4 moves down, and when two relative opening angles of crotch portion 22 are maximum, spring 6 is subject to pulling force minimum.
Use operating process is as follows:
When needs lift, hoisting rope is hung on suspension hook 2, the pulling force making progress along with steel rope, suspension rod 4 is also along with pulling, at this moment need the cooperation of operating personal, make suspension rod 4 drive two suspension hooks 2 to rotate, after crotch portion 22 sealings of two suspension hooks, owing to hanging thing Action of Gravity Field, the tack structure that lifts piece 41 of suspension rod 4 lower ends can be mutually stuck with the platform section 24 of two suspension hooks 2, prevents that two suspension hooks 2 are loosening.When lifting operation finishes, looseness of steel wire ropes, spring 6 pulls suspension rod 4 to move downward, and drives suspension ring 42 to open, and rope comes off.Refer to drawing suspension hook 2 closures and suspension hook 2 and open figure.
In order to be that crotch portion 22 laminating of two suspension hooks is more firm, both are semicircle by cross-sectional plane, and relative binding face adopts and be with concavo-convex tenon structure, and this structure also increases the intensity of suspension hook 2.As shown in Figure 2.
Cargo hook gear of the present utility model is only applicable to 5 tons with interior lifting operation.
