Abstract
The utility model relates to a control device for the closing speed of a fire-proof stage curtain. The control device comprises a fire-proof curtain plate (1), traction equipment (2), a basic counter weight (3), and speed reducing counter weights (4.1) to (4.n), in fire disaster, the fire-proof curtain plate (1) is in a free falling state by releasing a contracting brake inside the traction equipment (2), and fan fast falls under the traction of self weight, the basic counter weight (3) synchronously ascends under the traction, and the speed reducing counter weights (4.1) to (4.n) on a bottom support can be sequentially pulled, and as the kinetic energy is gradually reduced, the falling speed of the fire-proof curtain plate (1) is gradually reduced along with the gradual loading of weight of the speed reducing counter weights until the fire-proof curtain plate (1) falls and is closed. The control device has the main beneficial effects that the mechanical structure is simplified, the equipment volume is reduced and the cost is lowered, and is simple and reliable and free from maintenance and a standby power supply.
Description
Technical field
The invention belongs to mechanical transmissioning technology field, especially a kind of stage fireproof curtain closing speed control device.
Background technology
The fireproof curtain using in the critical facilitys such as stage, market, library, museum, requirement can be under the condition of power-off, segmentation is with different speed, the closure of landing from fast to slow, to can isolate fast burning things which may cause a fire disaster, make again personnel withdraw if having time, existing fireproof curtain closing operator, or volume is larger, or complex structure, what even have also needs to provide stand-by power supply.
Summary of the invention
Technical problem to be solved by this invention is for prior art above shortcomings, a kind of stage fireproof curtain closing speed control device is provided, adopts this device, can greatly simplify frame for movement, reduce equipment volume, reduce cost of investment, safe and reliable, Maintenance free.
The technical scheme that the present invention solves its technical problem employing is:
A kind of stage fireproof curtain closing speed control device, it is characterized in that: described fireproof curtain closing speed control device is by fireproof curtain plate (1), pulling equipment (2), basic counterweight (3), deceleration counterweight (4.1) to (4.n) forms, described fireproof curtain plate is along trapped orbit lifting, described pulling equipment (2) traction fireproof curtain plate (1) rises, described basic counterweight (3) is connected with described fireproof curtain plate (1) by jockey, and both traffic directions are contrary, the weight of fireproof curtain plate (1) described in described basic counterweight (3) partial offset, described deceleration counterweight (4.1) to (4.n) is comprised of n group deceleration counterweight, every group of deceleration counterweight is comprised of one or more counterweights again.
Beneficial effect of the present invention is mainly manifested in: can simplify frame for movement, reduce equipment volume, reduce cost of investment, safe and reliable, Maintenance free, without stand-by power supply.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is the second building form of counterweight of slowing down in overall structure of the present invention, with (5.1) to (5.n), represents.
The specific embodiment
Below by the specific embodiment, also describe the present invention by reference to the accompanying drawings.
The specific embodiment of the invention one: as shown in Figure 1, fireproof curtain plate (1) is connected with pulling equipment (2), basic counterweight (3) respectively by steel wire rope or chain, during normally without fire, pulling equipment (2) rises to the normal position of eminence by fireproof curtain plate (1) traction, and pins this position by the inner band-type brake of pulling equipment (2).Now basic counterweight (3) is in lowest order, the deceleration counterweight (4.1) to (4.n) hanging under basic counterweight (1) falls within bottom support bracket, only has basic counterweight (3) by steel wire rope, to connect the deadweight of fireproof curtain plate (1) counteracting part fireproof curtain plate (1).During fire, discharge the inner band-type brake of pulling equipment (2), this equipment is just in free falling state, under the traction of fireproof curtain plate (1) deadweight, pulling equipment (2) discharges steel wire rope, fireproof curtain plate (1) hurtles down, basic counterweight (3) synchronously rises under its traction, and order pulls out the deceleration counterweight (4 being positioned on bottom support bracket.1), (4.2),,, (4.n), with the weight of deceleration counterweight, load gradually, fireproof curtain plate (1) is because kinetic energy reduces, falling speed reduces gradually, until fireproof curtain plate (1) landing is closed.Adjust deceleration counterweight the adding a little and weight of (4.1) to (4.n), the speed closed requirement of landing from fast to slow while reaching fireproof curtain plate (1) closure.
In the specific embodiment of the invention one, what deceleration counterweight (4.1) to (4.n) adopted is steel loop chain class, or the larger flexible chain of other proportions, hang under basic counterweight (3), along with the rising of basic counterweight (3), increase gradually its quantity.Adjust hanging position and the quantity of deceleration counterweight (4.1) to (4.n), the deceleration point of capable of regulating fireproof curtain plate (1) and in, end closing speed, and adjust the weight of basic counterweight (3), the fastest closing speed of capable of regulating fireproof curtain plate (1).
The specific embodiment of the invention two: in the present embodiment, operation principle is with the specific embodiment one is basic identical above, difference be deceleration counterweight (4.1) in Fig. 1 to (4.n), by the n chunk shape deceleration counterweight (5.1) to (5.n) in Fig. 2, replaced.This kind of mode makes fireproof curtain plate (1) closing speed be divided into the deceleration of n section, has clear and definite deceleration point.
The specific embodiment of the invention three: pulling equipment (2) is placed between the steel wire rope or chain that fireproof curtain plate (1) is connected with basic counterweight (3), fireproof curtain plate (1) is implemented to rising driving, pinning, release control, and the operation principle of other parts is identical with the specific embodiment one or the specific embodiment two.
