Embodiment Construction

[0028] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0029] Such as Figure 1-3 Shown, a kind of bridging type safety door construction elevator comprises car 1, is provided with the safety door 2 of vertical lifting on the import and export of car 1, and the bottom plate of car 1 is positioned at an end of import and export and is connected with bridging board 3, and bridging board 3 is rotatably connected with the bottom plate of the car 1, and the bridging plate 3 is connected with the safety door 2 through a retractable assembly;

[0030] The retractable assembly includes a fixed pulley 4 and a steel wire rope 5. Both sides of the car 1 are provided with a fixed pulley 4. One end of the steel wire rope 5 is connected to the end of the tower bridge deck away from the car 1, and the other end bypasses the fixed pulley 4 and the safety door 2. conne...

Abstract

The invention relates to the technical field of construction elevators, in particular to a bridged safety door construction elevator. The bridged safety door construction elevator comprises a car; a vertical-lifted safety door is arranged in an access port of the car; one end, positioned in the access port, of a baseplate of the car is connected with a bridging plate; and the bridging plate is rotationally connected with the baseplate of the car, and is connected with the safety door through a receiving / releasing module. The bridged safety door construction elevator saves use of such materials as steel pipes, buckle pieces and dense-mesh nets, achieves green construction requirements, saves the construction cost, needs no mutual matching with a safety protection frame body in elevator installation, accelerates the mounting construction speed of an external elevator, creates conditions for advanced construction of a secondary structure, has no need to build an external safety protection frame body for the external elevator, saves labors, saves the construction cost, prevents aerial construction, and eliminates potential safety hazards caused by building of the external safety protection frame body.

Description

technical field [0001] The invention relates to the technical field of construction elevators, in particular to a construction elevator with a bridge type safety door. Background technique [0002] The construction elevator belongs to a kind of construction elevator, which is a manned and cargo-carrying construction machine often used in buildings, and is generally equipped with a safety door. The traditional process is that a corresponding safety protection frame needs to be erected between the construction elevator and the building, and then the external elevator is installed. After the elevator reaches the rear floor during use, the construction personnel and corresponding goods can only arrive at the construction site after passing through the safety protection frame. on site. [0003] At present, before building a construction elevator, a safety protection frame needs to be erected first. This construction method has the following disadvantages: [0004] 1. Waste mate...
