Passenger cage supporting and limiting device

Abstract

The invention provides a safer and more reliable passenger cage supporting and limiting device. The passenger cage supporting and limiting device comprises a supporting frame, a sliding chute, a supporting and limiting rod and a starting device, wherein the sliding chute is fixed on the supporting frame; the supporting and limiting rod is arranged on the sliding chute; the sliding chute serves as a rail on which the supporting and limiting rod moves back and forth; and the starting device is arranged on the supporting frame and used for controlling the supporting and limiting rod to be standby or on station. The supporting and limiting rod is on station under the condition that the passenger cage is static relative to a platform, so no great impact is generated, and the influence on other parts of a system is small; and besides, the supporting and limiting rod supports the lower part of the passenger cage, so the deflection of the passenger cage is smaller compared with the conventional mode that the upper side of the passenger cage is controlled by an escape compartment locking mechanism. Therefore, the passenger cage supporting and limiting device is very safe and reliable.

Description

technical field [0001] The invention relates to a locking support and position-limiting device for a passenger-carrying car of high-rise building fire-fighting equipment. Background technique [0002] CN101293125A discloses a reciprocating lifesaving device, which has an escape cabin locking mechanism that resets automatically, and the locking mechanism mainly acts on the top beam of the escape cabin with a certain radian. When the passenger car goes up, the striker is automatically pushed back. After the passenger car is in place, the striker automatically resets and supports the top beam of the passenger car, thereby realizing positioning and locking. After the striker is moved out, the lock can be released. [0003] In order to avoid large deflection of the passenger car when people enter the passenger car, guide pulleys are often set on the passenger car, and corresponding guide grooves are set on the frame to reduce the deflection, so as to achieve range that people ca...

Problems solved by technology

But in actual use, the effect is not very good. When the manned car goes up, first the guide pulley on the manned car is in contact with the guide groove on the frame. , the collision has the greatest impact on the cable, followed by the manned car, once a danger occurs, the injury to the personnel is fatal
