Abstract

The invention relates to a dressed stone lifting device for building construction. The dressed stone lifting device for building construction comprises a first clamping arm and a second clamping arm,the middle positions of the first clamping arm and the second clamping arm are assembled in a rotating mode, the upper end of the first clamping arm is provided with a connecting structure used for being connected with a lifting rope, the lower end of the first clamping arm is rotationally assembled with a first clamping plate, the upper end of the second clamping arm is provided with a connectingstructure used for being connected with the lifting rope, the lower end of the second clamping plate is rotationally assembled with a second clamping plate, the first clamping plate and the second clamping plate are driven by corresponding clamping arms to be close to or away from each other so as to being used for clamping and releasing dressed stones, a first reset spring is arranged between the first clamping arm and the first clamping plate, and a second reset spring is arranged between the second clamping arm and the second clamping plate. According to the device, the lifting rope is connected to the upper ends of the first clamping arm and the second clamping arm, the clamping plates at the lower ends of the first clamping arm and the second clamping arm are close to each other under the action of gravity, in the lifting process, the first clamping arm and the second clamping arm have no trend to be separated from each other, so that the probability of falling of the stressed stones in the lifting process is reduced.

Description

technical field [0001] The invention relates to a lifting device, in particular to a stone lifting device for building construction. Background technique [0002] A large number of stones will be used in the road construction process. At present, the transportation of the stones is mainly carried out manually. Due to the heavy weight of the stones, this brings inconvenience to the handling operations of the construction personnel on site, and there is labor intensity. Large and low construction work efficiency [0003] The Chinese invention patent with the authorized notification number CN207792498U discloses a steel plate lifting device. The steel plate lifting device includes a suspension ring. The lower end of the suspension ring is provided with a hanging column. Hook II; the hook I is connected to a cross bar through a rotating shaft, and the lower side wall of the cross bar is provided with evenly distributed card slots, and the card slots are matched with the post pr...
