Abstract
The invention provides an elevator having an anti-falling function. The elevator comprises a car, a lifting device and limiting rails, wherein the lifting device is connected with the car; the car is provided with an accommodating tank; an anti-falling device is arranged in the accommodating tank, and comprises a centrifugal limiting rod and a spring; the centrifugal limiting rod is rotationally arranged in the accommodating tank; one end of the spring is connected with the car, and the other end is connected with the centrifugal limiting rod; and the limiting rails are arranged at the two sides of the car, and are provided with multiple limiting clamping grooves fitting the centrifugal limiting rod. The elevator adopts a pure mechanical principle, so that the structure is simple, safe and reliable, the manufacturing cost is low, a greater effect on the prevention of personal and object harm caused by sudden out-of-control falling of the elevator is achieved, and a greater protection effect on the daily life of common people and the production of enterprises and public institutions is achieved.
Description
Technical field
The present invention relates to elevator technology field, particularly relate to a kind of elevator with anti-falling function.
Background technology
The existing safety device overwhelming majority of used during elevator falling that prevents have employed electronic component, easily cause maloperation, erroneous judgement, and also having restriction in service life, have a power failure suddenly in the process especially run at elevator, 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, cause extreme loss to the production of daily life and enterprises and institutions.
Summary of the invention
The technical problem to be solved in the present invention is according to above-mentioned the deficiencies in the prior art, provides a kind of pure theory of machines, structure simple, safe and reliable, the cheap elevator with anti-falling function.
Technical scheme of the present invention is as follows:
There is an elevator for anti-falling function, comprise car, jacking system and limit track; Described jacking system is connected with car, and described car is provided with storage tank, is provided with falling proof device in described storage tank; Described falling proof device comprises centrifugal position-limited lever and spring, and described centrifugal position-limited lever is rotatably arranged in described storage tank, and described spring wherein one end connects described car, and the other end connects described centrifugal position-limited lever; Described limit track is arranged at described car both sides, and described limit track is provided with several spacing draw-in grooves coordinated with described centrifugal position-limited lever.
Further, described storage tank is arranged at described cage bottom.
Further, be provided with bearing in described storage tank, described centrifugal position-limited lever is installed on described storage tank by described bearing.
Further, described centrifugal position-limited lever is wedge shape.
Further, described jacking system is hauling rope.
Compared with prior art, the embodiment of the present invention has following beneficial effect: when elevator normal operation, and the pulling force of spring to centrifugal position-limited lever equals the gravity of centrifugal position-limited lever, and centrifugal position-limited lever is accommodated in storage tank, does not affect car lifting; When the car of elevator is out of control fall time, whole elevator is in state of weightlessness, the pulling force of spring to centrifugal position-limited lever is greater than the gravity of centrifugal position-limited lever, spring contraction also drives centrifugal position-limited lever outwards to open to stretch out storage tank, centrifugal position-limited lever inserts in the spacing draw-in groove of limit track, and car is stopped falling.In time again car being mentioned, centrifugal position-limited lever skids off under gravity and resets from spacing draw-in groove, does not affect car lifting.The present invention is owing to have employed pure theory of machines; so structure is simple, safe and reliable, cheap; for prevent elevator suddenly the personnel that cause and the item spoilage of falling out of control serve great role, great protective effect is served for the daily life of the common people and the production of enterprises and institutions.

Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail.
As depicted in figs. 1 and 2, embodiments of the invention, a kind of elevator with anti-falling function, comprises car 1, jacking system and limit track 6.Described jacking system is hauling rope 5, and hauling rope 5 is connected with car 1 and drives car 1 to be elevated, and is provided with storage tank 2 bottom described car 1, is provided with two falling proof devices in described storage tank 2.
Described falling proof device comprises centrifugal position-limited lever 3 and spring 4.Described centrifugal position-limited lever 3 is wedge shape, and the heavier one end of described centrifugal position-limited lever 3 is installed in rotation in described storage tank 2 by bearing.Described spring 4 wherein one end connects described car 1, and the other end connects the middle part of described centrifugal position-limited lever 3.Described limit track 6 is arranged at described car 1 both sides, and described limit track 6 is provided with several spacing draw-in grooves 7 that can coordinate with described centrifugal position-limited lever 3.
As shown in Figure 3, when elevator normal operation, the pulling force of spring 4 to centrifugal position-limited lever 3 equals the gravity of centrifugal position-limited lever 3, and falling proof device does not operate, and centrifugal position-limited lever 3 is accommodated in storage tank 2, does not affect car 1 and is elevated.
As shown in Figure 4, when the car 1 of elevator is out of control fall time, whole elevator is in state of weightlessness, falling proof device is excited to operate, the pulling force of spring 4 to centrifugal position-limited lever 3 is greater than the gravity of centrifugal position-limited lever 3, spring 4 shrinks and drives centrifugal position-limited lever 3 outwards to open and stretches out storage tank 2, and centrifugal position-limited lever 3 inserts in the spacing draw-in groove 7 of limit track 6, and car 1 is stopped falling.In time again car 1 being mentioned, centrifugal position-limited lever 3 skids off under gravity and resets from spacing draw-in groove 7, does not affect car 1 and is elevated.
The present embodiment have employed pure theory of machines; structure is simple, safe and reliable, cheap; for prevent elevator suddenly the personnel that cause and the item spoilage of falling out of control serve great role, great protective effect is served for the daily life of the common people and the production of enterprises and institutions.
Above disclosedly be only present pre-ferred embodiments, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the claims in the present invention are done, still belong to the scope that the present invention is contained.
