Embodiment

[0023] Embodiment: a kind of elevator lifting and lowering anti-misshift mechanism (see attached Figures 1 to 4), including the anti-mis-movement component and the traction component. The anti-mis-movement component includes two safety pin mounting brackets 2 respectively installed at the two diagonal positions of the car top frame 1. The safety pin 3 is connected with a drive link mechanism between the two safety pins, and a driving arm 4 driven by a drive motor is hinged on one safety pin. The output shaft of the drive motor is connected to the turntable, and the drive arm is hinged at the edge of the turntable. The drive link mechanism includes successively hinged on the rotating arm 5, the first safety pin synchronous lever 6, the transfer arm 7, the second safety pin synchronous lever 8, and the triangular connecting plate 9, one end of the rotating arm is hinged on the driving arm, and the triangular connecting plate The three corners are respectively hinged to the sec...

Abstract

The invention discloses an elevator lifting mistaken movement preventing mechanism, and aims at overcoming the defects that elevator running leveling precision is low, traction mechanism braking reliability is not good, and safety is not high. The elevator lifting mistaken movement preventing mechanism comprises a mistaken movement preventing assembly. The mistaken movement preventing assembly comprises two safety pin installing frames arranged at the two opposite-angle positions of an elevator car top frame correspondingly, the safety pin installing frames are provided with safety pins capable of outwards stretching out, a driving connecting rod mechanism is connected between the two safety pins, and a driving arm pushed by a drive motor is hinged to one safety pin. The mistaken movementpreventing assembly is triggered during elevator car leveling, the drive motor works and drives the driving arm to push the safety pin to outwards stretch out, meanwhile, the driving connecting rod mechanism drives the other safety pin to outwards stretch out, the two safety pins outwards stretch into leveling inserting holes so that accurate positioning can be achieved, and elevator running leveling precision is ensured.

Description

technical field [0001] The present invention relates to an elevator, more specifically, it relates to an elevator lifting and lowering anti-mis-movement mechanism. Background technique [0002] As a kind of lifting equipment, elevators are widely used in high-rise buildings. Although elevators have high maintenance frequency and high safety factor, some minor faults may still occur, such as elevator trapped people, low elevator leveling accuracy, and troublesome elevator rescue. At present, with the development of the economy, the demand for villas is also increasing. Correspondingly, home elevators suitable for villa buildings have also become popular. Its manufacturing standards are different from those of normal elevators, and the supervision system is also different. Villa elevators are not included in the scope of special equipment supervision, and no statutory inspection is carried out. Therefore, it is very likely that the safety performance of the elevator cannot be ...
