Description

Quick unloading method and car for freight elevator in construction engineering

technical field

The invention relates to a fast unloading method and a loading device for building construction, especially a method for shortening unloading time, improving transportation efficiency, shortening the construction period, improving the cleanliness of the ground around the building, improving safety, reducing construction costs and improving environmental protection. A fast unloading method and a car for a construction freight elevator.

Background technique

During the construction of existing high-rise buildings, tower cranes or lifting freight elevators, or tower cranes and lifting freight elevators are generally used to transport building materials to desired locations.

Existing lifting goods elevator generally comprises the protective fence that is positioned at ground, the guide rail frame standard section that increases gradually with floor height, car, the driving structure that drives car to move up and down, is positioned at the control box in protective fence and car. The driving structure generally adopts a rack and pinion type or a wire rope type. The car generally includes a box body, a side-by-side elevator door set on the box body, and a motor for driving the side-by-side elevator door opening and closing. During the use of this type of car, the workers on the ground first carry the building materials into the car, and the car rises to the designated floor under the action of the driving structure, and then the workers unload the goods manually. Due to the structure of the side-opening elevator doors, generally only two or three workers can carry the building materials at the same time. After all the building materials have been moved, the lifting cargo elevator will move down to the ground for the next building material loading and handling. When workers are unloading, the elevator car must be located at the unloading floor, and the next building material handling can only be carried out after the workers have finished unloading, and an unloading platform needs to be built on the floor of each floor. In essence, bamboo springboards or wooden springboards are fixed between the scaffolding of the outer wall and the floor slabs of each floor. The amount of consumables is quite large, the cost of use is high, and there are potential safety hazards. Based on cost budget and construction cost control, the existing conventional method is to build a discharge platform every 3 to 5 floors, most of which use 5 floors to build a discharge platform, so that the transfer cost of building materials remains high and the progress of building materials in place Slow, affecting the progress of the project.
