Abstract

The invention provides a lifting device capable of performing one-way locking. The lifting device comprises a supporting frame (3), a lifting motor (94) installed on the supporting frame (3), a lifting platform (91) and a one-way locking assembly installed on the supporting frame (3), wherein the lifting platform (91) performs lifting movement through a threaded sleeve (92) driven by a screw rod (93) linked by the lifting motor (94), and the one-way locking assembly comprises an upper swing locking rod (81) and a lower swing locking rod (61) which are linked to the left side and the right side of the threaded sleeve (92) on the supporting frame (3) correspondingly.

Description

technical field [0001] The invention relates to the field of lifting equipment, in particular to a lifting device capable of one-way locking. Background technique [0002] In lifting equipment, the lifting of objects often faces the danger of accidental slipping. This danger can be avoided by using a threaded lifting device. However, long-term stress to weight can cause damage to the thread form, increasing the risk of thread deformation and possibly shortening service life. Contents of the invention [0003] The object of the present invention is to provide a one-way lockable lifting device, which can overcome the above-mentioned defects in the prior art. [0004] A lifting device that can be locked in one direction according to the present invention includes: a support frame, a lifting motor installed on the support frame, and a lifting platform for lifting movement through a threaded sleeve driven by a screw connected to the lifting motor and a one-way locking assemb...
