Abstract
An anti-falling protective device for an elevator comprises a frame, a plate type spring and a rubber roller. The bottom surface of the frame is a plate which is provided with a rectangular opening and a through hole, the bottom surface is perpendicularly and fixedly connected with a vertical plate on one side, rib plates are fixedly connected on two sides of the bottom surface and the vertical plate, rectangular through holes are longitudinally arranged on the rib plates on two sides, the rubber roller is disposed between the rib plates on two sides, two shafts of the roller penetrate through the through holes on the rib plates, a fixing device for fixing the plate type spring is arranged outside the rib plates, and the other side of the plate type spring is pressed on the roller shafts to enable the roller to move longitudinally. During usage, the anti-falling protective device is fixed at the top of an elevator car, so that an elevator slipway penetrates through the U-shaped opening on the bottom surface of the frame, and the roller presses the slipway. When the elevator is out of control and falls, the roller moves upwards to be clamped between the device and the slipway, and the car does not fall any more. The anti-falling protective device has the advantages of being simple in structure, safe and reliable and playing a great protective role in preventing casualties and object damages caused by sudden falling of incontrollable elevators.
Description
Technical field the utility model relates to safety guard, especially a kind ofly can prevent elevator because out of control and the safety guard fall suddenly takes place.
The existing safety device overwhelming majority of used during elevator falling that prevents of background technology has adopted electronic component, cause maloperation easily, erroneous judgement is disconnected, and also have service life, and especially in the process that elevator is moving, having a power failure suddenly, electronic component just can not play a role, very easily fall because of get out of hand, not only cause article to damage, also very easily cause the generation of human casualty accident, caused very big loss to the production of daily life and enterprises and institutions.
The summary of the invention the purpose of this utility model is to provide a kind of safety guard that prevents used during elevator falling pure mechanical simple in structure, safe and reliable, cheap.
The utility model comprises support body, leaf spring, rubber roll.The support body bottom surface is the concave shape that has the oblong gap, evenly be furnished with the open-work that to twist bolt from the gap far-end, at the vertical affixed oblong riser from gap far-end limit, the affixed floor that is rectangle between the angle of bottom surface and the formation of riser both sides, on the floor of both sides, vertically be furnished with the rectangular open-work with certain gradient, and between the floor of both sides, be furnished with rubber roll, two axles of roller pass the open-work on the floor of both sides, in through-hole position a fixedly side of leaf spring of anchor fitting is arranged in both sides floor outside vertical, the opposite side of leaf spring is pressed in the roller shaft highlight.
After adopting said structure, this device is fixed by bolts to the elevator cage top, the elevator slideway is passed in the concave shape gap of support body bottom surface, and make roller be pressed on the slideway and can roll flexibly.When the elevator get out of hand becomes free-falling body to fall, the pulling force that forms when downward acceleration due to gravity is during greater than the elastic force of leaf spring, roller will move to top, again because open-work and elevator slideway on the floor have certain included angle, roller clip is between this device and slideway, and when friction force was enough big, cab just no longer continued to fall.
Description of drawings is scheme drawing of the present utility model.
The specific embodiment comprises support body 1 in the scheme drawing of the safety guard that prevents used during elevator falling shown in the figure, leaf spring 2, rubber roll 3.The support body bottom surface is the concave shape that has the oblong gap, evenly be furnished with the open-work 4 that to twist bolt from the gap far-end, at the vertical affixed oblong riser 6 from gap far-end limit, the affixed floor that is rectangle between the angle of bottom surface and the formation of riser both sides, on the floor of both sides, vertically be furnished with the rectangular open-work 5 with certain gradient, and between the floor of both sides, be furnished with rubber roll, two axles of roller pass the open-work on the floor of both sides, in through-hole position a fixedly side of leaf spring of anchor fitting 8 is arranged in both sides floor outside vertical, the opposite side of leaf spring is pressed in the roller shaft highlight.7 is the elevator slideway.During use, this device is fixed on the elevator cage top, the elevator slideway is passed in the concave shape gap of support body bottom surface, and roller is pressed on the slideway and can rolls flexibly.When the elevator get out of hand becomes free-falling body to fall, the pulling force that forms when downward acceleration due to gravity is during greater than the elastic force of leaf spring, roller will move to top, again because open-work and elevator slideway on the floor have certain included angle, roller clip is between this device and slideway, and when friction force was enough big, cab just no longer continued to fall.Owing to adopted pure theory of machines; so it is simple in structure, safe and reliable, cheap; for preventing that elevator personnel and the article infringement that causes of falling out of control suddenly from having played great role, played great protective effect for the common people's daily life and the production of enterprises and institutions.
