Embodiment 1

[0038] Such as Figure 1-5As shown, a fast and precise hoisting device for prefabricated stairs in this embodiment includes a box body 1 , a movable support 7 , a fixed support 9 , a positioning adjustment mechanism and a fixing mechanism 11 . Described box body 1 is processed into cuboid structure, and its inside is processed with inner chamber body, is used for installing positioning adjustment mechanism, and its top both sides is connected with suspension ring 14 (such as figure 1 As shown in , the two lifting rings 14 are symmetrically installed on the top of the box body 1 near the two ports), and the lifting rings 14 are processed into a U-shaped structure, made of stainless steel, and the setting of the lifting rings 14 facilitates the connection between the crane and the lifting device. Connect to facilitate the installation and disassembly of the hoisting device. The movable bracket 7 is installed on the positioning adjustment mechanism, and is slidably installed on ...

Embodiment 2

[0041] Such as Figure 1-5 As shown, a fast and precise hoisting device for prefabricated stairs in this embodiment, its main structure is basically the same as in Embodiment 1, the main difference is that the positioning adjustment mechanism includes a servo motor 2, a rotating shaft 3 and a positioning sleeve 4. Such as figure 1 and figure 2 As shown, the servo motor 2 is installed on the side of the inner cavity of the box body 1 away from the fixed bracket 9, the end of the output shaft of the servo motor 2 is provided with a partition, and the partition is processed with a through hole for the rotating shaft 3 to pass through. , A bearing seat is installed in the through hole. One end of the rotating shaft 3 passes through the partition and is connected with the output shaft of the servo motor 2, and the other end is also installed on the side wall of the casing 1 through a bearing seat, and the outer side of the rotating shaft 3 is provided with a positioning sleeve 4...

Embodiment 3

[0045] A fast and precise hoisting device for prefabricated stairs in this embodiment, its main structure is basically the same as in Embodiment 2, the main difference is that: Figure 1-3 As shown, the front and rear sides of the right end of the box body 1 are all bolted with mounting plates 8, the bottom of the mounting plate 8 is bolted with fixed brackets 9, and the bottoms of the movable brackets 7 and the fixed brackets 9 are located at both sides of the box body 1 and are provided with There is a first connecting seat 10 , a fixing mechanism 11 is arranged under the first connecting seat 10 , and a second connecting seat 12 is arranged on the top of the fixing mechanism 11 . A steel cable 13 is fixedly connected to the bottom of the first connecting seat 10 , and the bottom end of the steel cable 13 is fixedly connected to the second connecting seat 12 . The steel cable 13 is made of carbon steel wire, and the steel cable 13 is a three-twisted steel wire rope. The surf...

Abstract

The invention relates to the technical field of building construction equipment, in particular to a fast and accurate hoisting device and method for prefabricated stairs. The fast and accurate hoisting device comprises a box body, wherein a servo motor is bolted to an inner cavity of the box body; a partition plate is arranged at the right side of the servo motor; and a rotating shaft is bolted to an output shaft of the servo motor, the rotating shaft penetrates to the right side of the partition plate, and the rotating shaft is rotationally connected with the inner wall of the box body through a bearing seat; Through the specific structure design, the device is simple in structure and easy to manufacture, has the advantages of being capable of conveniently positioning and clamping the prefabricated stairs, suitable for the prefabricated stairs of different models, balanced and stable in the hoisting process, rapid to install and the like, and the problems that existing prefabricated stairs are high in installation accuracy requirement, however, on-site installation of the prefabricated stairs is relatively difficult, and the prefabricated stairs cannot be accurately positioned and fixed are solved, therefore, the hoisting work efficiency of the prefabricated stairs can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a fast and precise hoisting device and hoisting method for prefabricated stairs. Background technique [0002] Compared with traditional buildings, prefabricated buildings have the advantages of energy saving, emission reduction, green environmental protection, industrialized production, rapid construction, and shortened construction period, which can improve the core competitiveness of enterprises in the industrial chain and standardize the whole industry. The stairs of high-rise residential buildings mainly include cast-in-place stairs and prefabricated stairs. Among them, prefabricated stairs are more and more widely used in modern buildings due to their characteristics of convenient manufacture, easy standardization, mass production, energy saving and high installation efficiency. Prefabricated stairs need to use special hoisting devices during install...
