Problems solved by technology

[0004] The technical problem to be solved by the present invention is that when the existing hoisted triangular steel frame platform in the prior art needs to be lifted to adjust the position, it is necessary to use tower crane equipment to hoist and remove the supporting frame supporting the platform, and then use tower crane to hoist to a new floor Rebuild the support frame at the working position, and the installation work is time-consuming and labor-intensive. The purpose is to provide a lifting platform for the construction of elevator shafts in high-rise buildings.

Embodiment 1

[0037] Such as Figure 1 to Figure 8 Shown, a kind of lifting platform that the present invention is used for high-rise building elevator shaft construction comprises:

[0038] Workbench 1, the workbench 1 includes a rectangular frame welded by longitudinal beams and transverse beams and patterned steel plates, the longitudinal beams and transverse beams are made of channel steel, angle steel, rectangular steel pipes and other profile materials, and patterned steel plates are welded on the top of the rectangular frame, The workbench 1 provides a working platform for construction work. The workbench 1 is horizontally located in the elevator shaft 15 , a gap is provided between the edge of the workbench 1 and the side wall of the elevator shaft 15 , and the workbench 1 is lower than the top surface of the elevator shaft 15 .

[0039] The support corbel is fixedly connected to the bottom of the workbench 1, and the support corbel includes a first column 2 and a second column 3 f...

Embodiment 2

[0045] Such as figure 2 , image 3 with Figure 9 As shown, the present invention is a lifting platform for the construction of elevator shafts in high-rise buildings. Compared with Embodiment 1, the difference between this embodiment and Embodiment 1 is that rubber rolling wheel assemblies 4 are fixedly connected around the workbench 1, and the rubber rolling wheel assemblies 4 is connected with the rolling of the wall of elevator shaft 15. The bottom of the second column 3 is fixedly connected with a rubber rolling wheel assembly 4, which is rollingly connected with the wall of the elevator shaft 15, and the rubber rolling wheel assembly 4 moves vertically up and down in the elevator shaft 15 following the workbench 1.

[0046] Specifically: the rubber roller assembly 4 includes a mounting plate 41, a support frame 42, a compression spring 46, a compression spring positioning shaft 45, a spring push plate 47, a rubber roller 43, a roller shaft pin 44, and the left and rig...

Embodiment 3

[0049] Such as figure 1 , image 3 , Figure 5 to Figure 8 As shown, the present invention is a lifting platform for the construction of elevator shafts in high-rise buildings. The difference between this embodiment and Embodiment 1 is that the top of the shear key 7 rotates with the first column 2 through a straight pin in the elongated hole. Connected, the shear key 7 is fixedly connected with a T-shaped tie rod 17 on the side away from the elevator shaft door hole 16. One end of the T-shaped tie rod 17 is threadedly connected with the shear key 7, and after the bottom of the shear force key 7 stretches out from the elongated hole, the other end of the T-shaped tie rod 17 is offset against the side wall of the first column 2. After the bottom of the shear key 7 retracts into the elongated hole, the other end of the T-shaped tie rod 17 is away from the side wall of the first column 2, and the T-shaped tie rod 17 is used to control the rotation angle of the shear force key 7...

Abstract

The invention discloses a lifting platform for construction of an elevator shaft of a high-rise building. The lifting platform comprises a workbench, a supporting bracket, shear keys and a lifting drive device. A gap is formed between the edge of the workbench and the side wall of the elevator shaft. The supporting bracket is fixedly connected to the bottom of the workbench, and comprises first vertical columns and second vertical columns, wherein the first vertical columns and the second vertical columns are fixedly connected to the four corners of the bottom of the workbench. The shear keysare of long block structures, long holes for mounting of the shear keys are formed in the lower portions of the first vertical columns, the tops of the shear keys are rotationally connected into the long holes, and after stretching out of the long holes, the bottoms of the shear keys abut against the bottom face of a door opening of the elevator shaft. The lifting drive device is located between the two first vertical columns, the top of the lifting drive device is fixedly connected with the bottom of the workbench, the bottom of the lifting drive device abuts against the bottom face of the door opening of the elevator shaft, and the lifting drive device is used for driving the workbench to vertically move in the elevator shaft up and down. By means of the lifting platform, the erecting and lifting efficiency of an operating platform is improved.

Description

technical field [0001] The invention relates to the technical field of building construction tools, in particular to a lifting platform used for the construction of elevator shafts in high-rise buildings. Background technique [0002] In the building high-rise construction process, the formwork support of the four walls of the elevator shaft of each floor in the room mainly adopts the method of erecting an operation platform. At present, there are mainly the following construction methods for the formwork support operation platform on the inner wall of the indoor elevator shaft: the first layer of vertical poles are directly landed to build the frame body operation platform layer by layer to carry out the formwork support construction work; The formwork support construction work is carried out on the triangular steel frame platform through hoisting by tower crane equipment; the formwork support construction work is carried out on the lifting steel platform, etc. [0003] Ho...
