Embodiment 1

[0018] Example 1: When horizontal hoisting and translation are required:

[0019] First connect the main body frame 1 with the hoisting frame 4, start the locking oil cylinder 14, the locking telescopic rod 21 stretches and pushes the push plate 15 to move to the left, and the push plate 15 drives the adapter plate 13 to rotate and then drives the rotating shaft 24 to rotate, along with the rotating shaft 24 The rotating shaft 24 can drive the parallel four-bar linkage mechanism to automatically lock the locking cam 22. At this time, the locking of the main frame 1 and the hoisting frame 4 is completed, and the object to be hoisted is placed under the hoisting frame 4. The hoisting operation can be carried out by rotating the spinner 16 to realize the locking of the hoisting object. When hoisting, the boom 3 is lifted. During the lifting process, it is necessary to maintain the level of the spreader, start the pitching cylinder 7, and adjust the connection direction of the spr...

Abstract

The invention discloses a special lifting device capable of achieving adjustment and rotation at any angle. The special lifting device comprises a main body framework; a rotation seat is disposed in the middle of the main body framework; a rotation gear shaft is inserted into the rotation seat; a connecting arm is hinged to the top end of the rotation gear shaft; support lugs are fixedly connected to the side walls of the connecting arm and hinged to the bottom of the tail end of a suspension arm through pin shafts; a supporting plate is fixedly connected to the top end of the suspension arm; a pitch oil cylinder is hinged to the supporting plate; the tail end of a pitch retractable rod in the pitch oil cylinder is hinged to the top end of the connecting arm. By means of the pitch oil cylinder and a rolling oil cylinder, the adjustment of the lifting device at the angle in the horizontal direction is achieved, self rotation of the lifting device is achieved through a rotation oil cylinder and the rotation gear shaft without manual rotation, manpower consumption can be reduced, and the safety and lifting efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a hoisting tool, in particular to a special hoisting tool which can realize arbitrary angle adjustment and rotation. Background technique [0002] Chain spreaders such as hooks are commonly used in spreaders, while lifting suction cups, clamps and forks can be used as special spreaders on the crane for a long time, and can also be hung on the hooks as replaceable auxiliary spreaders. For temporary use, it is often used in multi-cargo warehouses and storage yards to improve operating efficiency. In order to meet the daily maintenance and lifting of large machinery, some domestic sling companies have also designed some special spreaders, such as fan spreaders, tower spreaders, blade spreaders, hub spreaders and other non-standard spreaders. However, the current spreader has the following problems. One is that the angle of the horizontal direction cannot be adjusted by itself duri...
