Detailed Description

The utility model is further described below with reference to the accompanying drawings.

The first embodiment is as follows:

as shown in fig. 1-3, a hoist with anti-swing device, including girder 2 and end beam 1, be provided with trolley 3 on the girder 2, trolley 3 includes the dolly frame, it is connected with reel 6 to rotate on the dolly frame, the speed reducer is installed to the one end of reel 6, install driving motor 5 on the speed reducer, telescopic link 9 includes a plurality of telescopic joints 11 along the flexible complex of vertical direction, the cross section of telescopic joint 11 is the rectangle structure, the rectangle structure can prevent telescopic joint 11 self from rotating, ensure that telescopic link 9 only can rise or descend along vertical direction, improve telescopic link 9's stability. The big record of external diameter is gone up the sleeve in the adjacent telescopic joint 11, and the little record of external diameter is gone up the sleeve in the adjacent telescopic joint 11, and the sleeve cover is established in the sleeve outside down, is provided with upper stop block and lower stop block on the upper telescopic inner wall, is provided with the slider on the telescopic outer wall down, and the slider slides between upper stop block and lower stop block. The winding drum 6 is wound with a steel wire rope 14, the steel wire rope 14 hanging from the winding drum 6 is arranged inside the telescopic joint 11, and the bottom end of the steel wire rope 14 is installed at the bottom of the telescopic joint 11 at the innermost part through a connecting piece 16.

Bottom fixedly connected with hoist 10 of telescopic joint 11 innermost, hoist 10 include mounting panel 12 and lifting hook 13, and mounting panel 12 fixed connection is in telescopic joint 11 innermost's bottom, and lifting hook 13 articulates in mounting panel 12 bottom, and the length of mounting panel 12 is greater than the width of telescopic link 9, and mounting panel 12 has certain limiting displacement, avoids telescopic joint 11 innermost to promote excessively and damage. An adjusting push rod 15 is hinged between the lifting hook 13 and the mounting plate 12, the angle of the lifting hook 13 can be adjusted by the adjusting push rod 15, and before or after the lifting is started or completed, the heavy object can be hung on the lifting hook 13 or taken down from the lifting hook 13 more easily by adjusting the angle of the lifting hook 13; during the lifting, the angle of the lifting hook 13 is adjusted to ensure that the heavy object is stably hung on the lifting appliance 10 and is not easy to fall off.

The principle of the utility model is as follows: when the winding drum 6 releases the rope, the telescopic rod 9 moves downwards under the action of the gravity of the telescopic rod and the lifting appliance 10; when the winding drum 6 is reeled, the telescopic rod 9 and the lifting appliance 10 move upwards under the action of the steel wire rope 14, so that the lowering and lifting of the heavy object are completed.
