Detailed Description

The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.

Example 1: the overhanging outer-protection upper fire blanket retracting device shown in fig. 3 and 7 comprises an outer-protection steel pipe, a roller assembly and a fire blanket.

As shown in fig. 1 and 2, the outer protection steel pipe is a framework of the outer protection, and is formed by alternately erecting two vertical steel pipes 4 and two horizontal steel pipes 5, and an inner connecting rod 7 is additionally arranged according to the erection span condition.

As shown in fig. 3 to 6, the roller assembly includes a first roller 11, a second roller 12, a third roller 13, and a fourth roller 14, the first roller 11 and the second roller 12 are disposed along the top and the bottom of one side of the outer protective steel pipe, the third roller 13 and the fourth roller 14 are disposed along the top and the bottom of the other side of the outer protective steel pipe, the first roller 11 and the second roller 12 both include an upper roller 8 and a lower roller 9, the lower roller 9 of the first roller 11 is connected to the lower roller 9 of the second roller 12 through a vertical rotating belt 2, the upper roller 8 of the first roller 11 is connected to the third roller 13 through a horizontal rotating belt 3, and the upper roller 8 of the second roller 12 is connected to the fourth roller 14 through a horizontal rotating belt 3.

As shown in FIG. 7, the fixed side 61 of the fire blanket is fixed to the steel pipe of the outer protective steel pipe, and the two corners of the horizontal rotating belt connecting side 62 of the fire blanket are fixed to the horizontal rotating belt 3, and the upper and lower fixing points are on the same side. When the vertical rotating belt 2 is pulled, the horizontal rotating belt 3 is driven to roll. At this time, since the fire blanket 6 is connected to the horizontal rotating band 3, the fire blanket 6 is driven to roll along the steel pipe side and fixed to the steel pipe side, and the fire blanket 6 is flexible and is collected like a curtain cloth.

The implementation process comprises the following steps: setting up external protection: according to safety regulations and on-site conditions, steel pipes with proper sizes are selected, the steel pipes are arranged vertically and horizontally, and outer protective steel pipes are erected.

Installing a roller system: firstly, welding two first rollers 11 and two second rollers 12 at the top and the bottom of one side of a horizontal steel pipe to ensure that the upper and lower rollers 9 can synchronously roll; the third roller 13 and the fourth roller 14 are welded at the top and the bottom of the other side of the horizontal steel pipe; a vertical rotating belt 2 and two horizontal rotating belts 3 are sequentially sleeved on the sleeve. After the assembly, a test was conducted to ensure that the vertical rotating belt 2 could drive the horizontal rotating belt 3 to rotate.

Laying a fireproof blanket 6: the safety net is still bound and fixed with the steel pipe outer frame, one side of the fireproof blanket 6 is bound and fixed with the steel pipe in the vertical direction, and two angular points on the other side of the fireproof blanket are connected to the horizontal rotating belts on two sides of the other end and are arranged on the same side. Ensure the firm connection and no slippage. The vertical rotating belt 2 can be tried to be pulled, and the fire blanket 6 can be freely stored. The entire outer protective system is then installed on the designated floor.

Use in windy weather: when windy weather occurs, a specially-assigned person arrives at each designated floor, and all the fireproof blankets 6 are folded to one side by pulling the vertical rotating belts 2. After waiting for the weather of strong wind to pass, the vertical rotating belt 2 is pulled reversely to open the fireproof blanket 6. Through simple pulling rotation band, can realize the quick receive and release of fireproof blanket 6, improve implementation efficiency, ensure the safety of outer protection under the strong wind weather.

As mentioned above, although the present invention has been shown and described with reference to certain preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
