For example, in industrial environments having radiation or corrosive atmospheres, such as hot rooms, chemical industries, and the like.

Optionally, the hoisting frame provided by the embodiment of the disclosure is suitable for a hoisting environment with a tight space and without the entrance of an operator. For example, in the working environment of conventional hoisting work, especially, the working environment has narrow space and is inconvenient for operators to enter the field for operation intervention.

Alternatively, the hooks 40 are arranged on the hook mounting locations 22 of the lifting legs 20 in a manner facing the same side.

The positioning function can be realized during connection, the correct connection position can be found conveniently, and the effect of preventing the rotation of the hoisting legs 20 can be realized after the fixed connection. In this embodiment, the connecting surface is a wall surface where the end of the horizontal hanging beam 11 is connected to the connecting end of the hanging leg 20.

Optionally, the anti-rotation structure 114 comprises a seam allowance. The connecting surface of the end part of the transverse hanging beam 11 is provided with a notch, so that the connecting end of the hoisting leg 20 is positioned in the rabbet, and the hoisting leg 20 is prevented from rotating while the connecting and positioning are realized.

Alternatively, the connecting surfaces of the two ends of the first transverse hanging beam 111 and the two ends of the second transverse hanging beam 112 are both provided with rabbets.

With reference to fig. 9 and 10, when the hoisting frame of the embodiment of the present disclosure is used, first, the longitudinal (X direction) and transverse (Y direction) hoisting points of the hoisted piece 60 are determined, and the length of the longitudinal hoisting beam 12 on the hoisting frame and/or the connection positions of the hoisting legs 20 on the transverse hoisting beam 11 are adjusted according to the hoisting points, so that the hoisting space formed by the four hoisting legs 20 is matched with the hoisting points of the hoisted piece 60. After a hoisting frame is hoisted by a lifting hook (also can be the grabbing tail end of a manipulator) of a crane, the hoisting frame is moved to the position near a hoisting point, then the hoisting frame is translated to enable the lifting hook 40 of the hoisting frame to enter a hoisting hole 61 of the hoisting point of a hoisted piece 60, then the hoisting frame is hoisted, the lifting hook 40 of the hoisting frame is hung with the hoisting hole 61 of the hoisting point on the hoisted piece 60, then the hoisted piece 60 can be hoisted, and the operations of moving the hoisted piece 60 and the like can be realized under the movement of the crane. And after the hoisting is completed, the hoisting frame is placed down until the hoisted piece 60 falls to the ground, then the hoisting frame is placed down for a certain distance, the lifting hook 40 of the hoisting frame is separated from the lifting hole 61 of the lifting point of the hoisted piece 60, and then the hoisting frame is translated, so that the separation of the hoisting frame and the hoisted piece 60 can be realized.

In some cases, the distance from the lifting point of the hoisted piece 60 to the upper surface of the hoisted point is different, and at this time, the installation position of the hook 40 can be adjusted, and the height of the hoisting leg 20 can be adjusted in the Z direction, so that the stability is further improved while the hook 40 can reach the position of the lifting point (the hoisting hole 61) of the hoisted piece 60.

In the hoisting frame of the embodiment of the disclosure, the hoisting frame is operated by a crane or a manipulator, so that the hoisting frame is inevitably provided with a hoisting point to ensure that the crane or the manipulator operates the hoisting frame. In some embodiments, the hoist frame further comprises a lifting point structure 50 disposed on the hoist frame 10. For use with the hook of a crane or the grabbing end of a robot arm.

Optionally, the lifting point structure 50 is disposed in a central position of the lifting frame 10. In the hoisting process, the balance of the hoisting frame is ensured.

Optionally, the lifting point structure 50 comprises a fixed plate 51 and a lifting ring 52, the fixed plate 51 is disposed on the longitudinal lifting beam 12, and the lifting ring 52 is disposed on the fixed plate 51.

In some embodiments, the number of longitudinal suspension beams 12 is two or more; two or more than two longitudinal hanging beams 12 are arranged in parallel to form a longitudinal hanging beam group; the transverse suspension beam 11 comprises a first transverse suspension beam 111 and a second transverse suspension beam 112; the first transverse hanging beam 111 is arranged at one end of the longitudinal hanging beam group, and the second transverse hanging beam 112 is arranged at the other end of the longitudinal hanging beam group. Stability and balance are enhanced.

Optionally, the lifting point structure 50 is disposed at a longitudinally intermediate position of the longitudinal set of suspension beams.

Optionally, the number of the longitudinal hanging beams 12 is two, and the two longitudinal hanging beams 12 are arranged in parallel to form a longitudinal hanging beam group. The fixed plate 51 of the hoisting point structural member 50 is arranged at the middle position in the longitudinal direction of the longitudinal hoisting beam group, and the hoisting ring 52 is arranged at the middle position of the fixed plate 51 between the two longitudinal hoisting beams 12.

Alternatively, when the longitudinal suspension beams 12 adopt the box beam structure as shown in fig. 2, the ring-shaped operating portion 1261 of the pin 126 is located inside the longitudinal suspension beam group, and the nut 127 is located outside the longitudinal suspension beam group. The location of the nut 127 on the outside facilitates the operation of the robot to socket the nut 127 onto the pin 126.

In some embodiments, the lifting frame further comprises rollers 23 disposed at the bottom of the lifting legs 20. The lifting frame is convenient to move.
