Embodiment 1

[0023] Additional aspects and advantages of embodiments of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of embodiments of the invention. combine Figure 1-Figure 3 , the embodiment of the present invention provides a lifting elevator shaft operating platform using a triangular support frame and a screw pull system, including: a platform 10, the platform 10 is a grid frame member formed by welding a plurality of square steels, and the platform 10 Patterned steel plates 6 are laid on the surface layer and its surroundings. The lower surface of the platform 10 is provided with a plurality of triangular support frames 4. The plurality of triangular support frames 4 are evenly arranged on both sides of the platform 10. The plurality of triangular support frames 4 pass through the wall respectively. The bolts 3 are fixedly connected to the concrete wall 5 inside the elevator shaft, a...

Embodiment 2

[0028] The embodiment of the present invention provides a method of using the hoisting elevator shaft operating platform using the triangular support frame and the screw pull system, specifically as follows:

[0029]The surface layer of the aluminum alloy platform 10 of the embodiment of the present invention is laid with a 3mm thick patterned steel plate 6, and the bottom keel is an integral structure welded by aluminum alloy square tubes of 40mm×70mm×1.5mm. Φ20mm round steel hoisting pull rings 7 are welded on the top, which are used for the fixed point of the tower crane hoisting wire rope. The bottom of the aluminum alloy platform 10 is supported by an aluminum alloy triangular support frame. The 100mm×5mm square steel gasket is welded, and is connected and fixed to the inner concrete wall of the elevator shaft through the 600mm long M12 wall-through bolt. During construction, the tower crane can be used to fix the hoisting steel wires on the two hoisting pull rings 7, and...

Abstract

The invention discloses a lifting type elevator shaft operation platform using a triangular supporting frame and a screw opposite-pulling system. The lifting type elevator shaft operation platform comprises a platform, a plurality of triangular supporting frames are arranged below the platform, and the triangular supporting frames are uniformly distributed on two sides of the platform; the triangular supporting frames are fixedly connected to a concrete wall in an elevator shaft through wall penetrating bolts, a plurality of split bolts are arranged on the two opposite vertical faces of the concrete wall correspondingly, the split bolts are located under the triangular supporting frames and horizontally fixed into the concrete wall, the two ends of the split bolt extend outwards correspondingly to form a limiting structure of the triangular supporting frame, and lifting pull rings are arranged on the edges of the two sides of the upper portion of the platform correspondingly and fixed to the platform in a welded mode. By means of the triangular supporting frame and the screw opposite-pulling system, operation is easy and convenient, safety, high efficiency, flexibility and convenience are achieved, portability of the operation platform is guaranteed, input of materials is reduced, the turnover rate of the operation platform is increased, and the application range is widened.

Description

technical field [0001] The invention belongs to the technical field of elevator shaft construction equipment, and in particular relates to a hoisting elevator shaft operating platform using a triangular support frame and a screw pull system. Background technique [0002] Elevator shafts are usually designed in the construction of high-rise buildings to provide installation locations and space for the installation of elevators. During construction, elevator shafts are prone to safety accidents such as falling from high places and being hit by objects, and are one of the larger sources of danger. The elevator shaft operation platform is widely used in construction sites as a safe operation platform facility in the elevator shaft. The traditional method generally adopts tool-type or I-steel cantilevered steel pipe scaffolding. Due to the high erection height, there are potential safety hazards, and the cost is relatively high, and the operation is inconvenient. Contents of th...
