Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contour of each component itself.

[0023] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0024] The present invention provides a hoisting platform for anti-fall structural engineering construction, comprising: a crane body 100, a hook mechanism 200 and a hook locking mechanism 300; the crane body 100 is provided with a telescopic boom 110, one end of the telescopic boom 110 is installed with a sling 120, and one end of the sling 120 is connected to a mounting cylinder 130; the hook mechanism 200 is installed on the mounting cylinder 130, the hook mechanism 200 comprises a sliding assembly and a hook 220, the sliding assembly is installed in the mounting cylinder 130, the hook 220 is installed on the sliding assembly, and the hook 220 is located outside the mounting cylinder 130; the hook locking mechanism 300 is installed in the mounting cylinder 130, and is used to lock the hook mechanism 200.

[0025] When hoisting an object, the object to be hoisted is hung on the hook 220. Then, under the action of the gravity of the heavy object, the heavy object drives the sliding assembly to move down to the lowermost limit position. While the sliding assembly slides downward, it drives the hook locking mechanism 300 to operate. The hook locking mechanism 300 locks the hook 220. Therefore, even if the heavy object shakes during the subsequent transfer of the heavy object, the heavy object will not fall off the hook 220, thereby realizing self-locking of the hook 220. Therefore, compared with the self-locking structure realized by the spring, it is more stable, reliable and durable.

[0026] In one embodiment, the sliding assembly includes an annular mounting plate 340 and a sliding rod. The annular mounting plate 340 is horizontally installed in the mounting cylinder. The sliding rod is slidably connected to the inner ring of the annular mounting plate 340. One end of the sliding rod passes through the bottom of the mounting cylinder 130. The sliding rod passes through one end of the mounting cylinder 130 to install the hook 220.

[0027] Furthermore, a limit plate is provided at the upper end of the sliding rod, and a return spring is provided between the limit plate and the annular mounting plate 340. The locking member 330 is connected to the second connecting rod assembly 320 through the vertical slider 323, and the vertical slider 323 is slidably connected to the inner wall of the mounting cylinder 130; the locking member 330 has an arc-shaped cross section, and a locking cap 331 is provided at one end of the arc-shaped rod to match the end of the hook 220. When the sliding rod moves to the limit position, the locking cap 331 just covers the end of the hook 220. When hoisting an object, the object to be hoisted is hung on the hook 220. Under the action of the gravity of the heavy object, the heavy object drives the hook 220 and the sliding rod to move down to the lowest limit position. The sliding rod slides downward and drives the first connecting rod 311 and the second connecting rod assembly 320 to move in turn. When the second connecting rod assembly 320 moves, the locking member 330 connected thereto also starts to move downward. When the locking member 330 moves to the lowest limit position, the locking cap 331 on the locking member 330 is connected to the end of the hook 220. The locking member 330 The other end is connected to the sliding rod, and a first magnet is provided on the sliding rod on the side facing the locking member 330, and a second magnet corresponding to the first magnet is provided on the locking member 330. Therefore, under the action of magnetic force, the locking member 330 locks the hook 220. Therefore, even if the heavy object shakes during the subsequent transfer of the heavy object, the heavy object will not fall off the hook 220; the lifting platform disclosed in the invention adopts a connecting rod assembly and a slider to achieve self-locking of the hook 220, so compared with the self-locking structure achieved by a spring, it is more stable, reliable and durable.

[0028] In one embodiment, the first link assembly 310 includes a first link 311 hinged to the sliding rod, the other end of the first link 311 is hinged to the second link 312 through a hinge shaft, the hinge shaft is rotatably connected to the inner wall of the mounting cylinder 130, and the second link assembly 320 includes a third link 321 hinged to the end of the hinge shaft, the other end of the third link 321 is hinged to the fourth link 322, and the lower end of the fourth link 322 passes through the lower end of the mounting cylinder 130 and is connected to the locking member 330. When the sliding rod slides downward with the weight, the first link 311, the second link 312 and the hinge shaft are driven to rotate in turn, and the hinge shaft drives the third link 321 and the fourth link 322 to move when rotating, and finally the locking member 330 slides downward under the action of the fourth link 322 and finally slides to a position where it contacts the hook 220 and can lock the hook 220.

[0029] In one embodiment, two mounting plates 340 are symmetrically arranged at the lower end of the sliding rod, a rotating shaft 350 is arranged between the two mounting plates 340, an incomplete gear 360 is arranged on the rotating shaft 350, the hook 220 is arranged on the incomplete gear 360, and a transmission assembly 370 for driving the incomplete gear 360 to rotate is also arranged between the hinge shaft and the rotating shaft 350. The transmission assembly 370 includes a transmission shaft 371 rotatably arranged on the lower side of the inner wall of the mounting cylinder 130, and also includes a first gear 372 arranged on the hinge shaft, a second gear 373 meshing with the first gear 372 is arranged on the transmission shaft 371, and also includes a third gear 374 coaxially arranged with the second gear 373, and the third gear 374 meshes with the incomplete gear 360. Therefore, when the hinge shaft rotates, the first gear 372 thereon starts to rotate. When the first gear 372 rotates, it drives the second gear 373, the transmission shaft 371, the third gear 374 and the incomplete gear 360 to rotate a certain angle in sequence. When the incomplete gear 360 rotates, the hook 220 fixedly connected thereto also deflects at a certain angle. Therefore, this can make the connection between the hook 220 and the locking member 330 more reliable.

[0030] In one embodiment, a horizontal shaft 131 is further disposed at the uppermost side of the installation cylinder 130 , a pulley 132 is disposed on the horizontal shaft 131 , and the sling 120 is connected to the upper end of the sliding rod 212 after passing around the pulley 132 .
