Abstract
The invention provides a safe electric lift. The safe electric lift comprises a lift car. The lift car is connected with a balance weight through a pulling rope. A vertical support column arranged in a lifting channel of the electric lift penetrates through the top face and the bottom face of the lift car. The support column extends along the whole lifting channel and is capable of freely rotating around the axis of the support column. The cross section of the support column is in the shape of a cam. The shape of through holes formed in the top face and the bottom face of the lift car correspondingly and allowing the support column to penetrate through is matched with the cross section of the support column, and friction plates are arranged on the inner circumferential faces of the through holes. When the central axis of the cross section of the support column rotates till the central axis of the cross section of the support column coincides with the central axes of the through holes, small gaps are formed between the friction plates of the inner circumferential faces of the through holes and the support column, and no sliding friction force exists between the friction plates and the support column. According to the safe electric lift, the lift car can be reliably prevented from falling rapidly when an automatic control system breaks down, so that the safe electric lift has high safety.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
Embodiment one:
In the embodiment one shown in Fig. 1, Fig. 2, this safe elevator comprises car 1; Described car 1 connects clump weight (non-invention main points, not shown) by drag rope; The end face 11 of described car 1 and bottom surface 12 by one be located at vertical pillar stiffener 2 in elevator lifting channel run through, described pillar stiffener 2 extends along whole hoist trunk, and this pillar stiffener 2 can rotate freely around own axes; The cross-sectional plane of described pillar stiffener 2 is cam-like, and the shape of through holes that the end face 11 of described car 1, bottom surface 12 supply pillar stiffener to run through and pillar stiffener cross-sectional plane match, and described through hole inner peripheral surface is provided with friction lining 13; When the cross-sectional plane axis of described pillar stiffener 2 rotates to and coincides with the axis of described through hole, that is the cross-sectional plane of pillar stiffener 2 and through hole form zhou duicheng tuxing, time as shown in Figure 2, between friction lining 13 on described through hole inner peripheral surface and pillar stiffener 2, there is minim gap, fricton-tight friction force between friction lining 13 and pillar stiffener 2.
In addition, the end of described pillar stiffener 2 can be engaged on elastic bearing, and described elastic bearing is after all outward forces of elimination, and bearing inner ring is reset to initial angle position under elastic-restoring force; Thus make pillar stiffener 2 remain the location status being the fricton-tight friction force of friction lining 13 in its natural state.
Above-mentioned safe elevator is in lifting process, as autonomous cruise speed system et out of order, when car 1 is out of control, passenger then in car 1 can pillar stiffener 2 described in manual rotation, because pillar stiffener 2 cross-sectional plane and described through hole are all in cam-like, when therefore pillar stiffener 2 rotates, friction lining 13 on pillar stiffener 2 perisporium squeezing through-hole internal perisporium, thus pressure braking action is formed to car 1, can autonomous cruise speed system be departed from and car reliably be braked, prevent it from falling fast.
Embodiment two:
Figure 3 shows that the embodiment two of safety cage lifter, the difference of itself and embodiment one is: also include a sleeve pipe 3 be nested with in described pillar stiffener 2 outside in described car 1, the cross-sectional plane of described sleeve pipe 3 and the cross-sectional plane of pillar stiffener 2 are all in cam-like; Described sleeve pipe 3 can be followed car 1 and be moved; Sleeve pipe 3 inside face is smooth, and without obvious force of sliding friction between pillar stiffener 2.Wherein, sleeve pipe 3 can be engaged in the bottom surface 12 of car 1 by rotating shaft; Also can not with car 1 axial restraint, axially can be free to slide along pillar stiffener 2, now structure is simple, but when car 1 speed is unstable, the lower end of sleeve pipe 3 may collide with the bottom surface 12 of car 1, forms noise.In the present embodiment two, after described sleeve pipe 3 is set, there are two outstanding advantages: one, the personnel taking this elevator can be directly hand steered on this sleeve pipe, alleviates fatigue of standing; Two, rotate described pillar stiffener 2 at needs, when braking car 1, hand can keep the gripping to sleeve pipe 3, drives pillar stiffener 2 to rotate by sleeve pipe 3, make pillar stiffener 2 continue pressing friction sheet 13, and need not worry to need because of the decline of car 1 to adjust the position of hand on pillar stiffener 2; This makes manual braking more convenient and potent.
