Problems solved by technology

It has application limitations: this structure can only be applied to places where the roller blinds are arranged in a straight line. As the height of the roller blinds increases, the weight and deflection of the roller bearings will increase, which will affect the operation of the roller blinds. The maximum span should not exceed 15m
Not suitable for installation and use in large-span and curved places

Embodiment 1

[0023] Such as Figure 1-Figure 3 As shown, the cable lifting type fire shutter is composed of a curtain surface 1, a lifting mechanism and a guide rail 2. Wherein, the lifting mechanism consists of a fireproof electric hoist 3, a reel 4, a transmission mechanism connected between the fireproof electric hoist 3 and the reel 4, a universal coupling connected between adjacent reels 4, A plurality of fixed pulleys 6 arranged on the top bracket 5 of the doorway of the building, a plurality of sheaves 7 arranged on the reel 4 corresponding to the fixed pulleys 6, and a plurality of horizontally evenly arranged on the curtain surface 1 Lifting is made up of wire rope 8, and in the present embodiment, adopts a reel 4, thereby does not need to be provided with universal coupling. The transmission mechanism is a chain transmission mechanism, which is composed of sprocket I9, sprocket II10 and chain 11 connected between the sprockets I, II9, and 10 respectively arranged on the fireproo...

Embodiment 2

[0029] Such as Figure 4 As shown, the cable lifting type fire shutter is composed of a curtain surface 1, a lifting mechanism and a guide rail 2. Wherein, the lifting mechanism is composed of a fireproof electric hoist 3, a reel 4, a transmission mechanism connected between the fireproof electric hoist 3 and the reel 4, and a universal coupling 16 connected between adjacent reels 4. , a plurality of fixed pulleys 6 arranged on the top bracket 5 of the door opening of the building, a plurality of rope pulleys 7 arranged on the reel 4 corresponding to the fixed pulleys 6, and a plurality of pulleys 7 evenly arranged on the curtain surface 1 in the transverse direction In this embodiment, the installation environment is U-shaped, so three reels 4 are used, which are respectively reels I, II and III, and two universal couplings 16 are arranged in total. The transmission mechanism is a chain transmission mechanism, which is composed of sprocket I9, sprocket II10 and chain 11 conn...

Embodiment 3

[0031] Such as Figure 5 As shown, the cable lifting type fire shutter is composed of a curtain surface 1, a lifting mechanism and a guide rail 2. Wherein, the lifting mechanism is composed of a fireproof electric hoist 3, a reel 4, a transmission mechanism connected between the fireproof electric hoist 3 and the reel 4, and a universal coupling 16 connected between adjacent reels 4. , a plurality of fixed pulleys 6 arranged on the top bracket 5 of the door opening of the building, a plurality of rope pulleys 7 arranged on the reel 4 corresponding to the fixed pulleys 6, and a plurality of pulleys 7 evenly arranged on the curtain surface 1 in the transverse direction In this embodiment, the installation environment is curved, and a plurality of reels 4 are used, and two universal couplings 16 are respectively arranged between the two reels 4. The transmission mechanism is a chain transmission mechanism, which is composed of sprocket I9, sprocket II10 respectively arranged on ...

Abstract

The invention provides a winding displacement lifting type fireproof roller shutter. The winding displacement lifting type fireproof roller shutter comprises a shutter surface, a lifting mechanism and guide rails; the winding displacement lifting type fireproof roller shutter is characterized in that the lifting mechanism is formed by a fireproof electric hoist, one or multiple rolling shafts, a transmission mechanism, universal couplers which are connected between every two adjacent rolling shafts, multiple fixed pulleys which are arranged on a top support of a building door opening, multiple rope wheels which are arranged on the rolling shafts and multiple lifting steel wire ropes which are horizontally and uniformly distributed on the shutter surface; the top end of the shutter surface is fixedly arranged on the top support of the building door opening; one end of each lifting steel wire rope is fixedly arranged at the bottom part of the shutter surface, and the other end of each lifting steel wire rope can ascend along the shutter surface and is fixedly arranged on the corresponding rope wheel by passing through the corresponding fixed pulley. Compared with an existing fireproof roller shutter, the winding displacement lifting type fireproof roller shutter is adapted to a large-span fireproof zone, a curved fireproof zone and a relatively-complex installation environment.

Description

technical field [0001] The invention relates to a cable lifting type fireproof roller shutter. Background technique [0002] At present, the commonly used fire shutter is a rolling vertical fire shutter. This shutter is composed of a curtain surface, a lifting mechanism, and a guide rail for embedding the curtain surface and guiding the movement of the curtain surface. The lifting mechanism is a fireproof electric starter. The shutter, the reel, and the transmission mechanism connected between the hoist and the reel are composed. The curtain surface is rolled on the reel, and the fireproof electric hoist drives the reel to realize the lifting or lowering of the curtain surface. It has application limitations: this structure can only be applied to places where the roller blinds are arranged in a straight line. As the height of the roller blinds increases, the weight and deflection of the roller bearings will increase, which will affect the operation of the roller blinds. The ...
