Embodiment 1

[0027] Embodiment 1: as Figure 1 to Figure 4 In the shown embodiment, a gear-driven lifting railing structure includes a railing body 1, a base body, a plurality of gear-link transmission structures and a driving structure for driving the gear-link transmission structure to move. The gear-link transmission structure includes two A symmetrically arranged single transmission mechanism 2, the single transmission mechanism includes a gear 21, an upper link 22 and a lower link 23, and the axes of all the gears are parallel to each other;

[0028] In a single transmission mechanism: one end of the upper link is hinged to one end of the lower link, the other end of the upper link is hinged to the railing body, the other end of the lower link is connected to the gear, and the gear is rotationally connected to the base;

[0029] In a gear linkage transmission structure: one of the single transmission mechanisms is provided with a pusher 4 for pushing the lower link in the single trans...

Embodiment 2

[0037] Embodiment 2: the basic structure and implementation mode of this embodiment are the same as embodiment 1, and its difference is, as Figure 5 to Figure 7 As shown in , the base body is provided with a vertical slide rail 6, and the railing body is provided with a guide slider 7, and the guide slider includes a fixed frame 71 connected with the railing body, a horizontal frame rod 72 slidingly matched with the fixed frame, a sleeve The adjusting spring 73 that is located on the horizontal frame bar, the wheel frame that is connected with one end of the horizontal frame bar and the scroll wheel 74 that is arranged on the wheel frame and cooperates with the vertical slide rail, the scroll wheel and the wheel frame are rotatably connected, and the horizontal frame bar can The sliding direction is horizontal and perpendicular to the axis of rotation of the scroll wheel. A stopper 75 is provided on the cross frame bar. One end of the adjustment spring is connected with the fi...

Abstract

The invention discloses a gear drive lifting rail structure which comprises a rail body, a base body, a plurality of gear-connection rod drive structures and a driving structure. Each gear-connection rod drive structure comprises two symmetrically-arranged single drive mechanisms. Each single drive mechanism comprises a gear, an upper connection rod and a lower connection rod. The driving structure comprises a pull rod and a driving cylinder, a cylinder body of the driving cylinder is hinged to the base body, a piston rod of the driving cylinder is hinged to a push part, the push part is provided with a sliding rod, and the push part comprises an upper push plate, a transverse push plate and an inclined push rod. The gear drive lifting rail structure has the beneficial effects of being reasonable in structure and capable of carrying out lifting protection when needing to be used and falling down to be folded when not needing to be used, having a good adaptive capacity, and being good in safety, convenient to adjust, capable of effectively protecting the safety of operators after ascending when applied to an operation platform, capable of preventing cargos at high places from falling down, beneficial to unloading cargos after descending, high in adjusting speed and high in firmness and reliability degree.

Description

technical field [0001] The invention belongs to the technical field of lifting railings, in particular to a gear-driven lifting railing structure. Background technique [0002] With the improvement of mechanization and automation in all walks of life, various horizontally moving or vertically lifting operating platforms, especially those used in special occasions in some special industries, continue to appear to meet the needs of different production and maintenance operations. Improve work efficiency and reduce labor intensity. These operating platforms must be provided with safety protection railings when personnel are operating to ensure personal safety. Most of the traditional railings of this type are fixed, welded or permanently assembled to the platform. For some platform equipment with limited space or limited transportation and movement size, manually installed railings have to be used. These railings are generally simple plug-in, hinged or fixed with temporary bo...
