Preferably, one end that the limiting plate and suspension hook are bonded to each other is both provided with outer tongue portion outstanding, and the two it Between all have identical radian.

Preferably, the length of the of length no more than connecting rod of the spring under natural conditions.

Preferably, magnetite block is provided on the top surface that the suspension hook is in contact with limiting plate, the magnetite block is by inlaying The fixed top for being laid on suspension hook.

Compared with prior art, the utility model has the beneficial effects that：With it is simple in structure, facilitate installing and dismounting, simultaneously It can also be easy to open, time saving and energy saving feature.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

- 3 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of research and development of double main bear multiple hanging point crane, It including sunpender 1 and suspension hook 2, is fixedly connected between the sunpender 1 and suspension hook 2, opening 3, the opening is offered on the sunpender 2 3 inner wall both ends are both provided with bearing 4, and limiting plate 5, the limiting plate 5 are fixedly connected with by strut between bearing 4 described in both sides It is both provided with outer tongue portion outstanding with one end that suspension hook 2 is bonded to each other, and all has identical radian between the two, it is described to hang Magnetite block is provided on the top surface that hook 2 is in contact with limiting plate 5, the magnetite block is by inlaying the fixed top for being laid on suspension hook 2 The other end in portion, the limiting plate 5 is flexibly connected with suspension hook 2, and the one end of the limiting plate 5 far from sunpender 1 passes through 6 activity of bull stick It is connected with connecting rod 7, the connecting rod 7 is arranged symmetrically, and the inner wall of the connecting rod 7 offers sliding slot 8, the bull stick 6 End close to 7 one end of connecting rod is installed with spring 9, the of length no more than connecting rod 7 of the spring 9 under natural conditions The other end of length, the spring 9 is fixedly connected with bar 10, and the spring 9 is located in sliding slot 8, the both ends point of the bar 10 Be not slidably connected sliding slot 8, and the groove 11 to match with bar 10 is offered on the suspension hook 2.

Operation principle

When limiting plate 5 and suspension hook 2 fit, spring 9 can pull back bar 10, such limiting plate 5, suspension hook 2 and connection It just links together between 7 three of bar；When opening, it is only necessary to pull down lever 10, the coefficient of elasticity of spring 9 need not be too Greatly, because even in use, when the upward pulling force of limiting plate 5 is larger, connecting rod 7 still will not be detached from groove 11 easily Range, except impersonal force by rotation can facilitate disengaging.
