The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The specific embodiment is as follows:

example 1, as shown in fig. 1 to 3, a multipurpose hoisting frame comprising a gantry 1, a hoist 2 and a spreader. The portal frame 1 is used for supporting on the ground, a winch 2 is arranged at the top end of the portal frame 1, a pull rope 21 extends downwards from the winch 2, and a hanging ring 22 is arranged at the lower end of the pull rope 21.

A lifting appliance is connected to the suspension loop 22. In this embodiment, the lifting appliance is provided with two types, namely a lifting hook mechanism 3 and a grappling hook mechanism 4.

The hook mechanism 3 includes a hook 31 and a first coupling member coupled to an upper end of the hook 31. The first coupling assembly includes a first hook 35, a first locking member 34, and a first elastic member 33. The lower end of the first hook 35 is connected with the upper end of the hook 31. The first locking member 34 is fitted over the first hook 35 at a position close to the hook 31, and a first locking hole 341 is formed at an upper end of the first locking member 34. A first elastic member 33 is provided between the first hook 35 and the first locking member 34. The first elastic piece 33 has upward elastic supporting force on the first locking piece 34 and drives the first locking piece 34 upward relative to the first hook 35, and the end of the first hook 35 far away from the hook 31 extends into the first locking hole 341, so that the opening of the first hook 35 is closed by the first locking piece 34; and the first elastic member 33 is compressed when the first locking member 34 is pressed downward, so that the opening of the first hook 35 is opened and hung on the hanging ring 22, and the coupling of the hook mechanism 3 and the pulling rope 21 is realized.

The grapple mechanism 4 includes a grapple 41 and a second connecting member. The second coupling assembly has the same structure as the first coupling assembly and includes a second hook 45, a second locker 44, and a second elastic member 43. The end of the second hook 45 is connected to the upper end of the grapple 41. The second locking member 44 is sleeved on the second hook 45 near the grapple 41, and a second locking hole (not shown) is formed at the upper end of the second locking member 44. The second elastic member 43 is disposed between the second hook 45 and the second locker 44. The second elastic member 43 elastically supports the second locking member 44 upward, and the end of the second hook 45 away from the grapple 41 is made to extend into the second locking hole, so that the second locking member 44 closes the opening of the second hook 45, and the connection of the grapple mechanism 4 and the pull rope 21 can be achieved through the second hook 45.

In this embodiment, a hook 11 is provided on the support arm of the gantry 1 for hanging the standby hook mechanism 3 or grappling hook mechanism 4, so as to facilitate storage of the spreader.

When the multipurpose hoisting frame of the embodiment is used and a heavy object needs to be hoisted by using the hoisting hook mechanism 3, the first locking member 34 is pressed downwards relative to the first hook 35, so that the opening of the first hook 35 is opened and the first hook 35 is hung on the hanging ring 22 at the lower end of the pull rope 21. Under the action of the elastic force of the first elastic member 33, the first locking member 34 moves upward relative to the first hook 35, and the end of the first hook 35 away from the hook 31 extends into the first locking hole 341, so as to close the opening of the first hook 35, thereby ensuring the firmness of the connection between the first hook 35 and the hanging ring 22 and improving the hoisting safety. The unused grapple mechanism 4 is hung on the hook 11 through the second hook 45, thereby reducing the trouble that the grapple mechanism is easy to lose when being placed freely.

Further, the first connecting assembly further includes a first stopping portion 32. The first stopper 32 is disposed at a connection portion of the first hook 35 and the hook 31, and protrudes outward in a circumferential direction of the first hook 35. More specifically, the two ends of the first elastic member 33 are respectively connected to the first stopping portion 32 and the first locking member 34, and the first stopping portion 32 is disposed to facilitate the connection of the first elastic member 33.

Suitably, the second connection assembly further comprises a second stop 42. The second blocking portion 42 is provided at a connection column of the grapple 41 and the second hook 45, and is provided to protrude outward in a circumferential direction of the second hook 45. More specifically, both ends of the second elastic member 43 are connected to the second blocking portion 42 and the second locker 44, respectively.

Further, the first elastic member 33 and the second elastic member 43 each employ a compression spring. The compression springs are respectively sleeved on the first hook 35 and the second hook 45. Specifically, one end of the compression spring sleeved on the first hook 35 abuts against the first stop portion 32, and the other end abuts against the first locking member 34; one end of the compression spring sleeved on the second hook 45 abuts against the second stopping part 42, and the other end abuts against the second locking part 44.

Further, the first hook 35 includes a first connecting rod 353, a first hanging rod 351 and a first limiting rod 352. The lower end of the first connecting rod 353 is connected to the upper end of the hook 31, and the first stopper 32 is disposed on the first connecting rod 353. The first hanging rod 351 is vertically connected to the upper end of the first connecting rod 353, and the first limiting rod 352 is connected to the end of the first hanging rod 351. More specifically, the first limiting rod 352 is rotatably connected with the first hanging rod 351, and the first limiting rod 352 can be rotated to be in the same straight line with the first hanging rod 351 and can be rotated to be perpendicular to the first hanging rod 351. In this way, the opening of the first hook 45 is opened more easily, facilitating the connection with the suspension loop 22.

Suitably, the second hook 45 includes a second connecting rod 453, a second hanging rod 451 and a second stopper 452. The second blocking part 42 is provided on the second connecting rod 453. The second hanging bar 451 is vertically connected to the upper end of the second connecting bar 453. The second limiting rod 452 is connected to the end of the second hanging rod 451, and the second limiting rod 452 and the second hanging rod 451 are rotatably connected to each other, so that the opening of the second hook 45 is larger.

The utility model is described above with reference to the accompanying drawings, it is obvious that the specific implementation of the utility model is not limited by the above-mentioned manner, and it is within the scope of the utility model to adopt various insubstantial modifications of the technical solution of the utility model or to apply the concept and technical solution of the utility model directly to other occasions without modification.
