Guiding type protecting frame and lifting method thereof

Abstract

The invention discloses a guiding type protecting frame which comprises vertical trusses, fixing devices, embedded parts and a frame body. The frame body is connected with the vertical trusses which are connected with the fixing devices. The fixing devices are connected with a building through the embedded parts. The guiding type protecting frame is characterized in that the fixing devices are arranged in the vertical direction of the frame body, guiding tracks are arranged on the vertical trusses, the guiding tracks of the vertical trusses are clamped in guiding shoes at the front ends of the fixing devices, at a fixing state, bearing locating pins penetrate into bearing ear plates of the fixing devices, and locating ear plates at the bottoms of the vertical trusses are clamped into the bearing locating pins. A lifting method of the guiding type protecting frame is characterized by comprising the steps that 1. at a lifting state, the fixing devices are arranged at the positions, corresponding to the top layer of the building, of the vertical trusses, a steel wire rope of a tower crane hook is used for being connected with the upper portions of the two vertical trusses, a tower crane hoisting mechanism is started, and the protecting frame is lifted by one floor; 2. in a lifting process, the locating ear plates of the vertical trusses can jack open the bearing locating pins, and the bearing locating pins move obliquely in oblique strip-shaped holes of the bearing ear plates of the fixing devices; 3. after lifting by a certain distance, the bearing locating pins are automatically reset due to gravity effect and fall to the bottoms of the oblique strip-shaped holes again, after the frame body is lifted to an appointed position, the steel wire rope is loosened, and the locating ear plates are clamped on the bearing lifting pins; and 4. a fixing device at the bottom layer is detached. The guiding type protecting frame has the advantages that the structure is simple, cost is low, operation is convenient, during frame body lifting, vertical operation along the guiding track can be carried out, frame body spinning and swinging aloft are avoided, collision is avoided, safety and reliability are achieved, multipoint inclination resistance is achieved, the probability that the frame body topples is greatly lowered, occupied tower crane time is short, frame body lifting time is saved, working of work types is not delayed, a single vertical truss is light in weight, and carrying and mounting are convenient.

Description

Technical field [0001] The invention relates to a guiding type protective frame and a lifting method thereof, in particular to a guiding type protective frame capable of ascending and running along a guide rail and a lifting method thereof. Background technique [0002] In the past, most of the exterior wall materials of high-rise buildings in China used ceramic tiles. Recently, due to the frequent occurrence of ceramic tiles falling off and causing injury and damage to safety accidents, they have gradually been replaced by paint. The best machine for paint application is a hanging basket. Therefore, in the construction phase of the external wall, the traditional scaffolding was replaced by the hanging basket. In the prior art, there is an external scaffold dedicated for main body construction, which is set up in sections along the building, formed at one time, and attached to the building. When the building rises one floor, the tower crane is used as the lifting power to lift i...

Problems solved by technology

However, there is no guiding device on this kind of external scaffolding. When the frame is lifted, it is often suspended at a high altitude. It is easy to spin and sway under the influence of wind or tower crane arm shaking, and it is easy to collide with adjacent frames, resulting in collision deformation or safety of the frame.
