Abstract

The invention discloses a lock-type hoisting device which comprises a supporting seat, a spreading shaft, an upper limited block, a drawing wheel, a lower limited block, a spreading pin and a bearing block, wherein the spreading shaft is inserted in a middle hole of the supporting seat, and the external lateral surface of a pin body of the spreading shaft is provided with threads; the upper limited block is fixed on the supporting seat; the central shaft of the drawing wheel is in thread fit with the spreading shaft; the lower limited block is fixed on the supporting seat, so that the spreading shaft can not rotate with the drawing wheel; the spreading pin is fixed on the supporting seat, and the upper part of the spreading shaft is nested into the spreading pin; and the bearing block is locked on the spreading pin. The lock-type hoisting device disclosed by the invention is simple in structure and easy to operate, can generate a large locking force, and does not fall off, thereby improving the security of the hoisting device.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a locking type hoisting device with simple structure. Background technique [0002] In production practice, the assembly or transportation of heavy objects such as large parts and components needs to be hoisted with the help of a spreader, such as a crane or a lifting mechanism. During the hoisting process, the transported heavy objects need to be locked and fixed on the spreader to ensure the safety of the hoisting process. [0003] Existing hoisting and locking mechanisms are generally commonly used bolt hoisting and locking mechanisms, gear hoisting and locking mechanisms and spring hoisting and locking mechanisms. For example, Chinese patent CN201325827 discloses a lifting device for an automatic locking hoisting device, which includes an upper beam and a lower beam. Vertical poles are symmetrically installed at both ends of the upper beam and the lower beam. Station installation bracke...
