Description

Technical Field

[0001] The present application relates to the field of fireproof rolling shutters, and particularly to a fully automatic self-lowering combined double-track double-curtain fireproof rolling shutter. Background Art

[0002] A fireproof rolling shutter door is a fireproof and heat-insulating facility designed specifically for large openings in buildings. It is characterized by a reasonable and compact structure and can realize the lifting and lowering of the rolling shutter through a transmission device and a control system, thereby playing a role in fire prevention and fire separation.

[0003] A double-track double-curtain fireproof rolling shutter is a type of fireproof rolling shutter door, which mainly includes a frame, a double-curtain rolling shutter, a fireproof curtain surface, and a rolling shutter driving member. Among them, the double-curtain rolling shutter and the fireproof curtain surface are arranged in sequence along the horizontal direction. The driving member is used to drive the double-curtain rolling shutter to lift and wind. The fireproof curtain surface is slidably matched vertically between two adjacent double-curtain rolling shutters. During the lifting and winding process of the double-curtain rolling shutter, the fireproof curtain surface rises and falls and winds together with the double-curtain rolling shutter to achieve a stable fire separation effect on the protected area. The rolling shutter driving member that drives the double-curtain rolling shutter to lift and wind usually releases the limit on the double-curtain rolling shutter when powered off, so that the double-curtain rolling shutter and the fireproof curtain surface move downward under their own gravity to achieve fire separation treatment of the protected area.

[0004] Regarding the above-mentioned prior art, the double-curtain rolling shutter moves downward relatively slowly under its own gravity, which is not convenient for quickly achieving fire separation treatment of the protected area. Content of the Utility Model

[0005] In order to enable the double-curtain rolling shutter to quickly descend when powered off, and thus quickly achieve fire separation treatment of the protected area, the present application provides a fully automatic self-lowering combined double-track double-curtain fireproof rolling shutter.

[0006] The fully automatic self-lowering combined double-track double-curtain fireproof rolling shutter provided by the present application adopts the following technical solutions:

[0007] A fully automatic self-lowering combined double-track double-curtain fireproof rolling shutter includes a frame, a double-curtain rolling shutter, a fireproof curtain surface, and a rolling shutter driving member. The rolling shutter driving member is used to drive the double-curtain rolling shutter to wind. It further includes a hammer pressing assembly. A plurality of double-curtain rolling shutters and fireproof curtain surfaces are arranged in sequence along the horizontal direction. The double-curtain rolling shutter includes two oppositely arranged first rolling shutter parts and a first base. The first base is fixedly installed on the two first rolling shutter parts and is located at the bottom of the two first rolling shutter parts. The fireproof curtain surface includes two oppositely arranged second rolling shutter parts and a second base. The second base is fixedly installed on the two second rolling shutter parts and is located at the bottom of the two second rolling shutter parts. The second base is located between the two first rolling shutter parts and on top of the first base. The hammer pressing assembly includes a first hammer pressing driving member and a first pressing hammer. The first pressing hammer is located on top of the first base, and the first hammer pressing driving member is used to drive the first pressing hammer to lift and lower.

[0008] By adopting the above technical solution, the hammer pressing driving member drives the first pressing hammer to perform a lifting motion in the vertical direction, which facilitates the first pressing hammer to press on the first base. Thus, when a fire breaks out and the rolling curtain driving member and the hammer pressing driving member are powered off and release the limiting effects on the double-curtain rolling curtain and the first pressing hammer respectively, the first pressing hammer quickly descends due to inertia and impacts the first base during the descending process. This is beneficial for accelerating the descending motion of the double-curtain rolling curtain to the position when it is in the fireproof state, and further facilitates quickly achieving the fire separation treatment of the protected area.

[0009] Optionally, the first hammer pressing driving member includes a first motor, a first rotating shaft, and a first connecting rope. The first rotating shaft is rotatably installed on the frame. One end of the first connecting rope is connected to the first rotating shaft, and the other end is connected to the first pressing hammer. The first motor is used to drive the first rotating shaft to rotate.

[0010] By adopting the above technical solution, when the first motor drives the first rotating shaft to rotate, the first connecting rope drives the first pressing hammer to perform a vertical motion, so that the vertical motion of the first pressing hammer is convenient and fast.

[0011] Optionally, two first connecting ropes and two first pressing hammers are provided. The two first pressing hammers are respectively located on both sides of the first rotating shaft. When the first rotating shaft rotates, the two first pressing hammers rise or fall together.

[0012] By adopting the above technical solution, the setting of the two first connecting ropes and the first pressing hammers is beneficial for further ensuring the stability when driving the first base, that is, the double-curtain rolling curtain, and there is no need to add additional driving force. It can be driven by the same motor, which is convenient and fast.

[0013] Optionally, the first hammer pressing driving member further includes two first fixed pulleys installed on the frame, and the two first connecting ropes are respectively wound around the two first fixed pulleys.

[0014] By adopting the above technical solution, the setting of the two first fixed pulleys plays a role in guiding and positioning the two first connecting ropes, and further facilitates ensuring the stability of the first connecting rope in use to ultimately ensure the stability of the first pressing hammer during vertical motion.

[0015] Optionally, it further includes a second hammer pressing driving member and a second pressing hammer. The second pressing hammer is located on the top of the second base. The second hammer pressing driving member includes a second motor, a second rotating shaft, and a second connecting rope. The second rotating shaft is rotatably installed on the frame. One end of the second connecting rope is connected to the second rotating shaft, and the other end is connected to the second pressing hammer. The second motor is used to drive the second rotating shaft to rotate.

[0016] By adopting the above technical solution, when the second motor drives the second rotating shaft to rotate, the second connecting rope drives the second pressing hammer to move in the vertical direction, so that the second pressing hammer presses on the second base during the descending process, thereby facilitating the rapid movement of the fireproof curtain surface to the position when it is in the fireproof state.

[0017] Optionally, two second connecting ropes and two second pressing hammers are provided. The two second pressing hammers are respectively located on both sides of the second rotating shaft. When the second rotating shaft rotates, the two second pressing hammers rise or fall together.

[0018] By adopting the above technical solution, the setting of the two second connecting ropes and the second pressing hammer is beneficial to further ensure the stability when driving the second base, that is, the fireproof curtain surface to move, and there is no need to add additional driving force. It can be driven by the same motor, which is convenient and fast.

[0019] Optionally, a flexible limiting slide bar is fixedly installed on the double-curtain rolling shutter, and the limiting slide bar abuts against one side of the fireproof curtain surface.

[0020] By adopting the above technical solution, the limiting slide bar plays a further limiting role in the vertical movement of the fireproof curtain surface, so that the fireproof curtain surface is not easily offset in the horizontal direction, which is beneficial to further ensure the stability of the fireproof curtain surface when moving in the vertical direction.

[0021] Optionally, a fireproof expansion sealing strip is provided along the vertical direction on one side where the two double-curtain rolling shutters face each other.

[0022] By adopting the above technical solution, when a fire breaks out, the fireproof expansion sealing strip expands due to heat, and connects the double-curtain rolling shutter and the fireproof curtain surface through the viscosity generated at high temperature, which is beneficial to enhancing the sealing performance between the double-curtain rolling shutter and the fireproof curtain surface, so that smoke is not easily exposed from the gap between the double-curtain rolling shutter and the fireproof curtain surface.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When a fire breaks out and the rolling shutter driving member and the hammer pressing driving member are powered off and release the limiting effects on the double-curtain rolling shutter and the first pressing hammer respectively, the first pressing hammer quickly descends due to inertia and impacts the first base during the descending process, which is beneficial to accelerating the descending movement of the double-curtain rolling shutter to the position when it is in the fireproof state, and thus facilitating the rapid implementation of the fire separation treatment for the protected area.

[0025] 2. The setting of the two first connecting ropes and the first pressing hammer is beneficial to further ensure the stability when driving the first base, that is, the double-curtain rolling shutter to move, and there is no need to add additional driving force. It can be driven by the same motor, which is convenient and fast.

[0026] 3. The limit slide bar plays a further limiting role in the vertical movement of the fireproof curtain surface, making it difficult for the fireproof curtain surface to shift horizontally, thus helping to further ensure the stability of the fireproof curtain surface during vertical movement.

[0032] The following further Figures 1-3 describes the present application in detail with reference to the accompanying drawings.

[0033] An embodiment of the present application discloses a fully automatic self-lowering combined double-track double-curtain fireproof rolling shutter. Referring to Figure 1 , the fully automatic self-lowering combined double-track double-curtain fireproof rolling shutter includes a frame 1, a hammer pressing assembly, a double-curtain rolling shutter 2, a fireproof curtain surface 3 and a rolling shutter driving member. Among them, the rolling shutter driving member is used to drive the double-curtain rolling shutter 2 to wind up. Specifically, the rolling shutter driving member includes a rolling shutter motor 4 and a rolling shutter rotating shaft 5. Two rolling shutter rotating shafts 5 are arranged in parallel and are both rotatably installed on the frame 1. The rolling shutter motor 4 is installed on the frame 1 and drives the two rolling shutter rotating shafts 5 to rotate synchronously through a sprocket and a chain.

[0034] Continue to refer to Figure 1, the double - curtain rolling shutter 2 includes two oppositely - arranged first rolling - shutter parts 201 and a first base 202. The tops of the two first rolling - shutter parts 201 are respectively fixedly installed on the two rolling - shutter rotating shafts 5. The first base 202 is located at the bottom of the two first rolling - shutter parts 201 and is fixedly connected to the two first rolling - shutter parts 201. When the rolling - shutter motor 4 drives the two rolling - shutter rotating shafts 5 to rotate, the two first rolling - shutter parts 201 perform winding and lifting movements, and synchronously drive the first base 202 to perform lifting movements.

[0035] Refer to Figure 1 and Figure 2 , the fire - proof curtain surface 3 includes two oppositely - arranged second rolling - shutter parts 301 and a second base 302. The second base 302 is located at the bottom of the two second rolling - shutter parts 301 and is fixedly connected to the two second rolling - shutter parts 301. The second base 302 is located between the two first rolling - shutter parts 201 and on top of the first base 202. A number of horizontally - arranged curtain - surface pressing strips 6 are uniformly arranged on the second rolling - shutter parts 301 along the vertical direction. Support ropes 7 are installed on the two bottom - most curtain - surface pressing strips 6. The tops of the support ropes 7 pass through each curtain - surface pressing strip 6 in sequence. When the two support ropes 7 are lifted and wound upwards, the two second rolling - shutter parts 301 are folded and stored under the overlap of the curtain - surface pressing strips 6.

[0036] Refer to Figure 1 and Figure 3 , the hammer - pressing assembly includes a first hammer - pressing driving part, a first pressing hammer 8, a second driving part, and a second pressing hammer 9. Among them, the first hammer - pressing driving part includes a first motor 10, a first rotating shaft 11, a first connecting rope 12, a first fixed pulley 13, and a supporting fixed pulley 14. Among them, the first motor 10 is installed on the frame 1 and is used to drive the first rotating shaft 11 to rotate. The first rotating shaft 11 is rotatably installed on the frame 1. One - end of the tops of the two support ropes 7 are fixedly installed on the first rotating shaft 11. When the first rotating shaft 11 rotates, the two support ropes 7 synchronously drive the two second rolling - shutter parts 301 to perform winding and lifting movements, and then synchronously drive the second base 302 to perform lifting movements. There are two supporting fixed pulleys 14. The two support ropes 7 are respectively located on both sides of the first rotating shaft 11. The two support ropes 7 are respectively wound around the two supporting fixed pulleys 14, so that the supporting fixed pulleys 14 play a role in guiding and positioning the supporting connecting ropes, facilitating ensuring the use stability of the supporting connecting ropes and ultimately ensuring the stability of the two second rolling - shutter parts 301 when moving along the vertical direction.

[0037] Refer to Figure 2 and Figure 3, one end of the first connecting rope 12 is connected to the first rotating shaft 11, and the other end is connected to the first pressing weight 8. The first pressing weight 8 is located on the top of the first base 202. When the first motor 10 drives the first rotating shaft 11 to rotate, the first connecting rope 12 drives the first pressing weight 8 to move in the vertical direction. There are two first connecting ropes 12, first pressing weights 8, and first fixed pulleys 13. The two first pressing weights 8 and first fixed pulleys 13 are respectively located on both sides of the first rotating shaft 11. The two first connecting ropes 12 are respectively wound around the two first fixed pulleys 13, so that the first fixed pulley 13 plays a role in guiding and positioning the first connecting rope 12, facilitating the stability of the first connecting rope 12 in use and ultimately ensuring the stability of the first pressing weight 8 during vertical movement.

[0038] When the first rotating shaft 11 rotates, the two first pressing weights 8 rise or fall together to drive the two first pressing weights 8 to move in the vertical direction synchronously by the same motor. When a fire breaks out and the rolling curtain motor 4 and the first motor 10 are powered off and release the limiting effects on the double-curtain rolling curtain 2 and the first pressing weight 8 respectively, the first pressing weight 8 quickly descends due to inertia and impacts the first base 202 during the descent, which is beneficial to accelerating the descent of the double-curtain rolling curtain 2 to the position when it is in the fireproof state, and then quickly achieving the fire separation treatment of the protected area. The setting of the two first pressing weights 8 facilitates the synchronous and rapid descent of the adjacent two double-curtain rolling curtains 2.

[0039] Refer to Figure 1 and Figure 3 , the second pressing weight 9 is located on the top of the second base 302. The second pressing weight driving member includes a second motor 15, a second rotating shaft 16, a second connecting rope 17, and a second fixed pulley 18. Among them, the second rotating shaft 16 is horizontally rotatably installed on the frame 1, the second motor 15 is installed on the frame 1 and used to drive the second rotating shaft 16 to rotate. One end of the second connecting rope 17 is connected to the second rotating shaft 16, and the other end is connected to the second pressing weight 9. When the second motor 15 drives the second rotating shaft 16 to rotate, the second connecting rope 17 drives the second pressing weight 9 to move in the vertical direction. There are two second connecting ropes 17, second pressing weights 9, and second fixed pulleys 18. The two second pressing weights 9 and second fixed pulleys 18 are respectively located on both sides of the second rotating shaft 16. The two second connecting ropes 17 are respectively wound around the two second fixed pulleys 18, so that the second fixed pulley 18 plays a role in guiding and positioning the second connecting rope 17, facilitating the stability of the second connecting rope 17 in use and ultimately ensuring the stability of the second pressing weight 9 during vertical movement.

[0040] When the second rotating shaft 16 rotates, the two second pressing hammers 9 rise or fall together, so as to synchronously drive the two second pressing hammers 9 to move in the vertical direction through the same motor. When a fire breaks out and the rolling curtain motor 4 and the second motor 15 are powered off and release the limiting effects on the double-curtain rolling curtain 2 and the second pressing hammer 9 respectively, the second pressing hammer 9 quickly descends due to inertia and impacts the second base 302 during the descent, which is beneficial to accelerating the downward movement of the fireproof curtain surface 3 to the position when it is in the fireproof state. The setting of the two second pressing hammers 9 facilitates the synchronous and rapid realization of the rapid descent of the two adjacent fireproof curtain surfaces 3.

[0041] Referring to Figure 2 and Figure 3 , to further ensure the stability of the fireproof curtain surface 3 when moving in the vertical direction, flexible limiting slide bars 19 are fixedly installed on two adjacent double-curtain rolling curtains 2. The limiting slide bars 19 of two adjacent double-curtain rolling curtains 2 abut against one side of the fireproof curtain surface 3 to play a limiting role in the vertical movement of the fireproof curtain surface 3. Fireproof expansion sealing strips 20 are arranged in the vertical direction on one side of the two double-curtain rolling curtains 2 facing each other. The fireproof expansion sealing strips 20 are located between the first rolling curtain part 201 and the second rolling curtain part 301. When a fire breaks out, the fireproof expansion sealing strips 20 expand due to heat and connect the first rolling curtain part 201 of the double-curtain rolling curtain 2 and the second rolling curtain part 301 of the fireproof curtain surface 3 through the viscosity generated at high temperature, which is beneficial to enhancing the sealing performance between the double-curtain rolling curtain 2 and the fireproof curtain surface 3, so that smoke is not easily exposed from the gap between the double-curtain rolling curtain 2 and the fireproof curtain surface 3.

[0042] The implementation principle of the fully automatic self-dropping combined double-track double-curtain fireproof rolling curtain in the embodiment of the present application is as follows: The first pressing hammer 8 and the second pressing hammer 9 respectively exert pressure on the double-curtain rolling curtain 2 and the fireproof curtain surface 3. When a fire breaks out and the rolling curtain motor 4, the first motor 10 and the second motor 15 are powered off and release the limiting effects on the double-curtain rolling curtain 2 and the first pressing hammer 8 respectively, the first pressing hammer 8 and the second pressing hammer 9 quickly descend due to inertia and impact the first base 202 and the second base 302 respectively during the descent, which is beneficial to accelerating the downward movement of the double-curtain rolling curtain 2 and the fireproof curtain surface 3 to the positions when they are in the fireproof state, and thus facilitates the rapid realization of the fire separation treatment of the protected area.

[0043] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
