Abstract

The utility model relates to the technical field of machine-room-less elevator equipment and particularly relates to a mechanical locking device capable of effectively preventing an elevator car from falling during the inspection and maintenance of host equipment. The mechanical locking mechanism of the elevator car comprises an upper beam arranged at the top of the elevator car, a locking means arranged at the left and right sides of the upper beam, and a fixing plate matched with the locking means. The side wall of the upper beam is provided with convex ribs used for fixing the locking means. The convex ribs are set to extend along the length direction of the upper beam. The locking means is composed of bolt seats arranged at the left and right ends of the upper beam, a bolt capable of axially moving within the bolt seats, and safety switches arranged outside the bolt seats. One end of the bolt is in the form of a locking end capable of being inserted into the fixing plate, and the other end of the bolt is in the form of a trigging end used for opening and closing the safety switches. The bolt is provided with a control rod used for controlling the bolt to move. The above mechanical locking mechanism of the elevator car is compact in structure, good in stability and high in safety performance. By means of the mechanical locking mechanism, the occurrence of safety accidents caused by the falling of the elevator car can be effectively avoided.

Utility model content

In order to overcome the deficiencies in the prior art, provide the mechanical lock mechanism of a kind of compact conformation, safety performance is good, productive costs is low lift car.

The utility model provides a kind of mechanical lock mechanism of lift car, comprise the upper beam that is installed on car top, be arranged at a upper beam left side, the blocking device of right both sides, the adapter plate matching with blocking device, it is characterized in that: on described upper beam sidewall, be formed with a fin for fixedly locked device, this fin extends along upper beam length direction, described blocking device comprises and is arranged at a upper beam left side, the plug housing at right two ends, can be in plug housing axially movable latch, be arranged at the safety switch outside plug housing, this latch one end is the keyed end that can be plugged on adapter plate, the other end is the trigger end for opening and closing safety switch, this latch is provided with the control stalk moving for controlling latch.

Further, fin is formed at the base of upper beam sidewall.

Further, plug housing comprises connecting panel and coaming plate, and this connecting panel is installed on upper beam sidewall, coaming plate is connected with connecting panel by bolt, and described fin and connecting panel and coaming plate surround the plug housing of sealing.

Further, coaming plate is provided with two bar shaped spacing holes that move for limiting control stalk.

Further, on permanent seat, have the bar hole coordinating with latch.

From above-mentioned to description of the present utility model; compared with prior art; its blocking device of the mechanical lock mechanism of the lift car that the utility model provides can directly be installed on the fin of upper beam; compact conformation, improve the stability of blocking device; the latch of car by upper beam two ends and adapter plate are pegged graft locked car and provide duplicate protection by safety switch, and safety performance is good, avoid the car initiation safety misadventure of falling.
