Safety system for building hoist

Abstract

The invention discloses a safety system for a building hoist. The safety system comprises a lifting cabinet, a cabinet door mechanism is arranged on the front side of the lifting cabinet, automatic push-out mechanisms are arranged on the front sides of the two sides of the lifting cabinet, and a U-shaped groove is formed in an inner cavity of the lifting cabinet. When the lifting cabinet suddenlystops, a blocking mechanism cancels blocking of a U-shaped air bag, the U-shaped air bag moves downwards in the inner cavity of the U-shaped groove due to inertia, and an air outlet mechanism rapidlyinflates the U-shaped air bag through movement of the U-shaped air bag, so that the U-shaped air bag rapidly expands to protect main parts of constructors, the aim of protecting safety of the constructors is achieved; and under the action of inertia, a support unloading mechanism pulls a supporting mechanism to move to cancel supporting for a bearing carrier plate, the bearing carrier plate descends and makes contact with a third spring, the third spring plays a role in buffering the bearing carrier plate, the lower limbs of the constructors and cargos can be protected, and therefore the purpose of safety protection is achieved.

Description

technical field [0001] The invention relates to the technical field of construction elevators, in particular to a safety system for construction elevators. Background technique [0002] Construction elevators are also called construction elevators for construction, and can also be used as outdoor elevators, hoisting cages on construction sites, and are often used in construction for manned and cargo-carrying construction machinery. They are mainly used for interior and exterior decoration of high-rise buildings, construction of bridges, chimneys, etc. Because of its unique box structure, the construction workers are comfortable and safe to ride. The construction elevator is usually used with the tower crane on the construction site. The general construction elevator has a load capacity of 1-10 tons and a running speed of 1-60m / min. There are many types of elevators. According to the operation mode, there are two types: without counterweight and with counterweight; according ...
