Embodiment Construction
[0016] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0017] Such as figure 1 As shown, the present invention is a rack and pinion anti-falling device running vertically, including a rack 1 , a moving plate 2 , a driving gear assembly 3 , a safety gear assembly 4 , a safety chain 5 and a detection device 6 .
[0018] In the present invention, the rack 1 is arranged in the vertical direction, and the moving plate 2 moves in the vertical direction through a linear guide rail. The linear guide rail includes a guide rail groove 7 and a slider 8 fixed with the moving plate 2 and movable along the guide rail groove. The driving gear assembly 3 , the safety gear assembly 4 and the detection device 6 are all fixed on the moving plate 2 . Such as figure 2 As shown, the driving gear assembly 3 includes a power assembly 301 fixed on the moving plate, a driving sprocket 302 for winding a safety chain, and...

The invention discloses a gear and rack anti-falling device running in the vertical direction. The device comprises a rack, a movable plate, a driving gear assembly, a safety gear assembly, a safety chain and a detection device, wherein the rack is arranged in the vertical direction, the movable plate can move in the vertical direction, the driving gear assembly is fixed to the movable plate, is actively engaged with the rack and is used for driving the movable plate to move, the safety gear assembly is fixed to the movable plate and is engaged with the rack in a driven mode, the safety chainis wound on the driving gear assembly and the safety gear assembly and is in a loose state under a normal working condition, and the detection device is used for detecting whether the safety chain istensioned or not. The gear and rack anti-falling device running in the vertical direction can prevent the device from falling instantly under the condition that a driving gear loses efficacy, only theextremely small falling stroke is generated, the safety of personnel and equipment is guaranteed, and extremely high safety and reliability are achieved.
Description
technical field [0001] The invention relates to an anti-falling device, in particular to an anti-falling device for a rack and pinion running in a vertical direction. Background technique [0002] At present, in the prior art, the rack and pinion anti-drop device running vertically is mainly the anti-fall safety device, which mainly relies on the centrifugal force generated when the load falls at high speed to push the block to move radially, and the block blocks the rack, thereby preventing the load from falling. This structure will only work after the load has fallen to a certain speed, so there must be a certain fall stroke, which is not suitable for short-stroke applications; at the same time, it may still cause damage to personnel and equipment during the fall stroke, and there is a safety hazard. risk. [0003] Therefore, it is urgent to solve the above-mentioned problems. Contents of the invention [0004] Purpose of the invention: The purpose of the present inven...
