Detailed Description

The utility model will be further explained with reference to the drawings.

The lifting appliance shown in fig. 1 to 3 comprises a cross beam 1, a plurality of rope hangers 2 connected with the lower bottom surface of the cross beam 1, a lifting hook hanging mechanism connected with the cross beam 1 in a sliding manner, and a telescopic mechanism 3, wherein two ends of the telescopic mechanism are respectively hinged with the lifting hook hanging mechanism and the cross beam 1; the hook hanging mechanism is provided with two side plates 4, at least two lower rollers 5 with two ends respectively connected with the bottoms of the two side plates 4, at least two upper rollers 6 with two ends respectively connected with the middle parts of the two side plates 4, and a hook connecting rod 7 with two ends respectively connected with the tops of the two side plates 4.

The working principle is as follows: the rope hangers 2 are arranged on the bottom surface of the cross beam 1, and the rope hangers at two ends of the cross beam 1 respectively hang lifting ropes; the lifting equipment hook is connected with a hook connecting rod 7 of the hook hanging mechanism. When lifting, if the gravity center position of the lifted object is not coincident with the hook hanging mechanism, the cross beam 1 is inclined when lifting, namely one end of the cross beam 1 tilts. The telescopic mechanism 3 is operated to drive the hook hanging mechanism to move along the beam 1 to the gravity center direction of the hoisted object, and the position of the hook hanging mechanism is adjusted to ensure that the position of the hook hanging mechanism and the gravity center of the hoisted object coincide in the direction vertical to the horizontal plane. The cross beam 1 is in a horizontal position during the hoisting process. As shown in fig. 4 and 5, the hoisting rope can be tied to the rope sling 2 in different positions during hoisting. The lower roller 5 and the upper roller 6 play a role in supporting and limiting, and simultaneously reduce the friction resistance when the hook hanging mechanism moves.
