Rotatable lift car toe guard

Abstract

The invention provides a rotatable lift car toe guard. The rotatable lift car toe guard comprises an upper toe guard piece (1) and a lower toe guard piece (2) which are hinged to each other, the lower portion of the lower toe guard piece (2) is provided with a bent portion (21) which is bent towards the inner side of a lift car, a torsion spring (5) is further connected between the upper toe guard piece (1) and the lower toe guard piece (2), a bent edge (211) is arranged at the joint of the upper end of the bent portion (21) and the lower toe guard piece (2), an upper rolling part (42) capable of rotating along the axial direction thereof is fixedly mounted on the bent edge (211), the lower end of the bent portion (21) is provided with a lower edge (212), and a lower rolling part (41) capable of rotating along the axial direction thereof is fixedly mounted on the lower edge (212). The lower toe guard piece can rotate relatively to the upper toe guard piece under the rolling action of the upper rolling part and the lower rolling part, rotational restoring force is provided through the torsion spring to enable the lower toe guard piece and the upper toe guard piece to restore to an unfolded state from a rotational state, and the rotatable lift car toe guard is simple in structure, low in cost, easier to manufacture and mount and more stable and reliable in working.

Description

technical field [0001] The invention relates to a car toe guard of an elevator, in particular to a rotatable car toe guard with simple structure and applicable to a shallow pit shaft to prevent the toe guard from squeezing the bottom of the pit. Background technique [0002] With the development of elevator technology, more and more elevator shafts are designed as shallow pit shafts, especially in villa elevators. When the bottom pit is less than a certain depth, common toe guards will squeeze the ground when the car runs to the bottom pit, causing damage to the toe guards, and may even cause injuries to related personnel. If you blindly adapt to the pit and shorten the car toe guard, the structure of the car toe guard will not meet the relevant standard requirements, and when the elevator car is at a higher floor station and is not at the leveling position, some passengers will fall into the elevator Well hazard. [0003] In order to solve this problem, there has been a d...

Problems solved by technology

However, because this kind of rotatable car toe guard adopts a very complicated cam linkage mechanism to realize the rotation of the toe guard, not only the manufacturing and installation process is complicated, but the manufacturing cost is high, and the reliability of the mechanism is relatively low, which is easy Damage, repair and replacement are quite troublesome
