Abstract
The utility model relates to a lateral movement fire resisting roller shutter with a chain traction device, which is characterized in that the chain in the chain disc is arranged on the tail end of the roller shutter, one end of each chain is connected with the cord fabric and its other end is connected with a bearing hang wheel in a channel steel rack, and each chain is connected with a chain wheel after connected in series. The whole system is in a stable mechanical state, and the system keeps a good forced direction and slide even in the angular velocity movement and the sliding wear won't occur; the bearable traction force of the chain traction is greatly larger than that of the steel wire, and the reliability is greatly enhanced; when the chain disc rotates, the radius of the traction shaft gradually largens along with the gradual largeness of the chain in the chain disc; therefore, the speed is lower and lower and realizes the angular velocity dynamic.
Description
Technical field
The utility model relates to fire-fighting equipment, particularly has the fire resisting shutter that is displaced sideways of chain haulage device.
Background technology
In the prior art, adopt the fire resisting shutter that is displaced sideways to have two kinds:
1. propelling movement type moves: shortcoming is that thrust makes every curtain sheet changed by force direction, increase along with distance, resistance is increasing, just can not promote again more after particularly turning round, and gait of march is slow, and when fire took place, the roller shutter closing time was long, may not in fire, in time play compartmentation, stop fire spread.
2. the steel wire traction formula moves: the mode that has adopted pulling, more reasonable than propelling movement type, but steel wire rope is not easy the location, steel wire will bear very big tractive force, the back steel wire except tractive force that turns round also will bear very big friction, sustains damage easily, just in case steel rope abrasion breaks, whole roller shutter just can't move, and also just can't stop fire spread.
Summary of the invention
The purpose of this utility model is intended to overcome the deficiencies in the prior art and the traction of a kind of employing extending type is provided, and frame for movement is new reasonable, produce wearing and tearing hardly in the motion, and motion has the fire resisting shutter that is displaced sideways of chain haulage device reliably.
The purpose of this utility model is achieved in that
A kind of fire resisting shutter that is displaced sideways with chain haulage device, comprise electric cabinet 1, water control case 2, motor 12, it is characterized in that the chain 12 in the chain drum that the end of roller shutter is provided with, one end of each chain is connected with cord 15, bearing hanging wheel 14 in the other end and the channel-section steel frame 13 is connected, and each chain 12 serial connection then is connected with sprocket wheel 3.
---described chain drum places in the lodge 7 of chain pallet 6, and chain places in the guide rail joint sealing 20.
---described chain 12 passes between jockey sprocket 5 and the auxiliary sprocket wheel 8 in the corner.
---be provided with spray header 4 and control magnetic valve 10 thereof in the guide rail joint sealing 20 of described chain 12.
---the fraction of described chain 12 and cord 15 places in the plate envelope 16 that is connected with angle-iron frame 19.
---the lower end of described cord 15 is provided with the pallet 9 that pulley is arranged at the bottom.
Advantage of the present utility model: 1, whole system is in a stable machine performance, even in angle speed motion, system keeps good be subjected to force direction and slip, does not have skimming wear; 2, adopt chain traction, its tractive force that can bear is more much bigger than steel wire, and reliability strengthens greatly; 3, when chain drum rotates, along with chain in the chain drum coils bigger and bigger, the radius that equals axis of traction is constantly big, so speed angle more and more, thereby realizes angle quick-action power.
Description of drawings
Fig. 1 is that the master of a kind of form of the utility model looks schematic diagram and partial enlarged drawing.
Fig. 2 is the longitudinal sectional view of the utility model chain haulage device.
Fig. 3 is a chain structure schematic diagram of the present utility model.
Fig. 4 is a chain drum structural representation of the present utility model.
In Fig. 1-Fig. 4: 1 electric cabinet, 2 water control casees, 3 sprocket wheels, 4 spray headers, 5 jockey sprockets, 6 chain pallets, 7 lodges, 8 auxiliary sprocket wheels, 9 pallets, 10 spray header control magnetic valves, 11 bodies of wall, 12 chains, 13 channel-section steel framves, 14 bearing hanging wheels, 15 curtain sheets, 16 plates envelope, 17 big cotton fire proof seal bars, 18 non-woven cloths, 19 angle-iron frames, 20 guide rail joint sealings, 21 motor, 22 button boxes.
The specific embodiment
During enforcement,, cast or stamp out sprocket wheel 3, jockey sprocket 5, the auxiliary sprocket wheel 8 of the steel chain 12 that meets hardness and degree of drawing and corresponding coupling earlier by designing requirement with reference to Fig. 1-Fig. 4; Make channel-section steel frame 13 with 50 channel-section steels, place on the angle-iron frame 19, be connected with the upper end of chain 12 between placement bearing hanging wheel 14, two hanging wheels in the channel-section steel frame, the lower end of chain is connected cord 15, the cord lower end connects non-woven cloth 18, and the major part of chain 12 and cord 15 is all placed in 1.5～2 plates envelope 16, installs motor 21, chain is placed the guide rail joint sealing, install spray header 4 and its control magnetic valve 10, install electric cabinet 1 and water control case 2 after, just finish the utility model.
