Problems solved by technology

[0003] The purpose of the present invention is to provide a self-locking integrated lifting mechanism to solve the problem that the existing lifting mechanism is prone to angle deviation and low stability during the position movement process. In addition, most lifting mechanisms require mechanical or electrical brakes. It brings additional design difficulties, and at the same time, most of the lifting mechanisms adopt linear drive mode, which requires a large volume and redundant structures

Abstract

The invention relates to a lifting mechanism, in particular to a self-locking type integrated lifting mechanism. The rotational movement of an existing lifting mechanism is limited through a guiding slide rail, and a large size and large friction force are caused; additional mechanical or electrical band-type brakes are needed, and the design difficulty is increased; a linear moving module is large in size and redundant in structure. According to the self-locking type integrated lifting mechanism, a connecting rod movement module is arranged on a fixing frame, a lifting platform is arranged on the connecting rod movement module, and a driving module is arranged on the fixing frame and connected with the connecting rod movement module. The middle of a driving connecting rod and the middle of a coupling connecting rod are hinged, one end of the driving connecting rod is hinged to one end of a first homologous output connecting rod, and the other end of the first homologous output connecting rod is hinged to the inner wall of a side plate. The other end of the driving connecting rod is fixedly connected with a worm gear. One end of the coupling connecting rod is hinged to one end of a second homologous output connecting rod, the other end of the second homologous output connecting rod is hinged to the fixing frame, and the other end of the coupling connecting rod is hinged to the inner wall of the corresponding side plate. The self-locking type integrated lifting mechanism is applied to lifting movement.

Description

technical field [0001] The invention relates to an integrated lifting mechanism, which belongs to the technical field of mechanical equipment. Background technique [0002] The lifting mechanism is widely used, mainly in industrial production. The lifting mechanism can quickly switch between different stations through a simple method. Most of the existing lifting mechanisms need guide rails to limit the rotational movement, which brings inconvenience in terms of structural volume and layout, and has a large impact on the gap and friction of the moving pair; in industrial operations Among them, stability is a necessary condition. Most of the existing lifting mechanisms require mechanical or electrical brakes, which brings additional design difficulties; most of the existing lifting mechanisms adopt linear drive mode, and the rotational motion of the motor is converted into the linear motion of the screw. Requires larger volume and redundant structure. These factors all limi...
