Abstract

The invention relates to an anti-drop device of a machine roomless car roof repairing platform. A lift car is fixed with vertical beams arranged on both sides of the lift car, a slideway is arranged outside the vertical beams, in the anti-drop device, a permanent seat is fixed on the inside of the vertical beams; a anti-drop frame is fixed on the vertical beams and the permanent seat, through-holes are arranged opposite to each other on the two corresponding end faces, an electrical switch is arranged inside the end faces; a fixed plate is fixed on the outside of the slideway, a location hole is arranged on the fixed plate; a spring is sleeved on a fixed rod, a raised panel capable of triggering the electrical switch is arranged on the fixed rod, the other end of the raised panel is provided with a jack for a bolt to penetrate; the fixed rod successively penetrates the two through-holes of the anti-drop frame and the location hole on the fixed plate from inside to outside, the raised panel contacts with the electrical switch, and the outside of the fixed plate is positioned by the bolt. The anti-drop device of the invention has the advantage that double functions of the mechanical orientation and the electric control are adopted so as to increase the work security; the clamping type fixed plate is used so that workers can stand in a safe position; and the spring is used to push the fixed rod back so as to avoid the danger caused by the carelessness of manual reset.

Description

technical field [0001] The invention relates to an anti-drop locking device for elevator inspection and maintenance, in particular to an anti-drop device for an elevator car top inspection platform without a machine room. The invention also relates to a method for installing the fall arrest device. Background technique [0002] The elevator adopts the machine room-less safety mode, so the car roof is used as the working area for the maintenance and inspection of the machines in the shaft. According to the law, when it is necessary to maintain or inspect the machine from the top of the car, in case of loss of control or unexpected movement of the car that may cause danger to the maintenance or inspection personnel, a mechanical locking device must be installed. [0003] The following problems generally exist in the existing anti-falling devices: the working platform is fixed at the same position; it needs to be reset by manpower, and it is easy to fail to reset to the end du...
