Description

Technical Field

[0001] The present invention relates to a flexible door for shipyards, and in particular to a flexible door for shipyards with a flame retardant function, which is applied in the technical field of stacking doors. Background Art

[0002] Flexible stacking doors are a new type of industrial door derived from traditional rolling shutter doors, generally referring to doors used in industrial warehouses and factories. They are usually driven by high-strength straps or servo motors for rapid lifting. The door body is made of flexible materials, mainly PVC materials, and will fold or roll up and stack upwards when opened.

[0003] Chinese invention patent CN201810188369.8 discloses "A fireproof rolling shutter door with good fireproof performance and anti-deformation ability". The sealing of the fireproof rolling shutter door is improved by means of a curtain plate and a base, and the ability of the fireproof rolling shutter door to prevent the spread of fire is further enhanced, thereby improving the fireproof performance of the fireproof rolling shutter door. At the same time, the first groove of the base can be cleaned by a cleaning mechanism to prevent the accumulated debris in the base from affecting the matching degree between the first groove and the curtain plate and causing a decrease in fireproof performance. The curtain plate is cooled by a cooling mechanism to prevent the curtain plate from being bent and deformed due to heat, thereby shortening the service life of the curtain plate, thereby extending the service life of the fireproof rolling shutter door.

[0004] In order to improve the fire retardant ability of the existing fireproof flexible door, a groove is installed at the bottom of the door frame when the flexible door is installed. When the flexible door is closed, the bottom of the door curtain is stuck in the groove to cover the gap between the curtain door and the ground, that is, the method of the curtain plate and the base of the above-mentioned invention. However, the groove installed at the bottom of the door frame will affect the flatness of the bottom of the door frame, thereby affecting the entry and exit of personnel and equipment into the flexible door. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the groove installed at the bottom of the door frame will affect the flatness of the bottom of the door frame, thereby affecting the entry and exit of personnel and equipment into the flexible door.

[0006] In order to solve the above problems, the present invention provides a shipyard flexible door with flame retardant function, comprising a door frame, a door curtain is fixedly connected to the top of the door frame, a door curtain crossbeam is fixedly connected to the bottom of the door curtain, a door frame groove is fixedly connected to the bottom of the door frame, and the door curtain crossbeam is correspondingly clamped with the door frame groove;

[0007] A slot plate cover is movably connected to the top of the door frame slot, the slot plate cover corresponds vertically to the door curtain crossbeam, and the upper surface of the slot plate cover is flush with the upper surface of the door frame slot, and a plurality of support holes are equidistantly provided on the surface of the slot plate cover, a rotating column is rotatably connected to the corresponding support hole in the middle of the door frame slot, the top end of the rotating column is plugged into the support hole, and a support block is fixedly connected to the outside of the top end of the rotating column, the support block contacts the lower opening of the support hole, and a through groove is provided at the edge of the support hole, and the through groove corresponds to the shape of the support block;

[0008] A fixed cylinder is fixedly connected to the rotating pipe column inside the door curtain beam, and a rotating bolt is rotatably connected to the inside of the fixed cylinder. The rotating bolt is plugged into the rotating pipe column, and a linkage bracket is slidably connected between the top of the fixed cylinder. The linkage bracket is hinged to the top of the rotating bolt, and a pushing cylinder is hinged between the linkage bracket and the door curtain beam.

[0009] In the above-mentioned shipyard flexible door with flame retardant function, the sealing and flame retardant effect of the flexible door is effectively improved by correspondingly connecting the door curtain beam with the door frame groove. At the same time, the door frame groove is restored and flattened by using the groove plate cover, which effectively reduces the impact of the door frame groove on the travel of the flexible door.

[0010] As a further improvement of the present application, the upper edge of the door frame groove is equidistantly fixedly connected with a limit stop page, the limit stop page corresponds to the top edge of the slot plate cover, and a cover plate spring is fixedly connected between the bottom of the slot plate cover and the middle of the door frame groove. The maximum rising height of the slot plate cover is limited by the limit stop page, thereby achieving the effect of flushing the slot plate cover with the upper opening of the door frame groove, and at the same time facilitating the installation of multiple sets of slot plate covers on the door frame groove to adapt to door frame grooves with longer lengths.

[0011] As a further improvement of the present application, the bottom of the rotating tube column is fixedly connected to a base plate, and return springs are fixedly connected between the two ends of the base plate and the inner wall of the door frame groove. The elastic force of the return spring is utilized to pull the base plate to realize the rotational recovery of the rotating tube column, that is, the rotating tube column is restored to the state of supporting the groove plate cover.

[0012] As a further improvement of the present application, the internal shape of the fixed tube corresponds to the support hole and the through groove combination, and the internal movably connected to the fixed tube is a straightening cover, which is sleeved on the rotating bolt to facilitate the rotating pipe column to directly enter the fixed tube after extending out of the support hole. At the same time, the specific shape of the fixed tube is used to limit the support block to prevent the rotating pipe column from restoring and rotating during the process of entering the fixed tube. The straightening cover is used to provide auxiliary support for the rotating bolt, thereby effectively improving the stability of the rotating bolt in the idle state.

[0013] As another improvement of the present application, a rotary lock mouth is opened on the top of the fixed tube, and the rotary lock mouth corresponds to the support block, and the lower surface of the straightening cover corresponds to the rotary lock mouth. When the rotating tube column extends to the top of the fixed tube, the rotating tube column performs a recovery rotation, allowing the support block to rotate and snap into the rotary lock mouth, thereby effectively improving the stable locking effect of the door curtain beam and the door frame groove.

[0014] As another improvement supplement of the present application, the bottom of the door frame groove is fixedly connected to a water flow groove, which corresponds to the door frame groove coaxially and vertically to the through groove. Dust and debris falling from the through groove directly fall into the water flow groove, and the dust and debris are brought out by the water flow in the water flow groove, thereby effectively improving the self-cleaning effect of the door frame groove.

[0015] As another improvement supplement of the present application, one end of the door frame groove is rotatably connected to a water-blocking gate, and the water flow groove corresponds to the bottom of the water-blocking gate. The water flow groove is intercepted by the water-blocking gate to fill the door frame groove with water, allowing the door curtain beam to be immersed in water, thereby effectively improving the fire prevention and cooling capacity of the door curtain beam.

[0016] As another improvement of the present application, a water-absorbent cotton block is fixedly connected to the inside of the door curtain crossbeam, and an outflow cover edge is fixedly connected to the top of the water-absorbent cotton block. Both the water-absorbent cotton block and the outflow cover edge are made of sponge material. The water absorption capacity of the water-absorbent cotton block and the outflow cover edge is utilized to achieve water drainage. In rainy days, the water outside the door frame groove can be drained into the water gutter for discharge. In the event of a fire, the door frame groove is filled with water, and the water in the door frame groove is drained out through the water-absorbent cotton block and the outflow cover edge, so that the door frame groove is in a humid state, thereby effectively improving the fire retardant effect.

[0017] As another improvement supplement of the present application, the bottom of the seepage cover edge contacts the outer edge of the door frame groove, and an outlet groove is provided on the bottom surface of the seepage cover edge. By providing the outlet groove, the water absorption and seepage effect of the seepage cover edge is effectively improved.

[0018] To summarize, the present invention lowers the door curtain beam to the door frame groove, and the rotating bolt is first inserted into the rotating column, and drives the rotating column to rotate, so that the support block rotates to the bottom of the groove, releases the support block for the groove plate cover, and allows the rotating column to extend out of the support hole and enter the fixed cylinder, completing the clamping combination of the door curtain beam and the door frame groove, and realizing the stable closure of the door body curtain to the door frame body, effectively improving the sealing and flame retardant effect of the flexible door, and subsequently after opening the flexible door, the door curtain beam is separated from the door frame groove, the rotating column rotates to restore, and the support block provides support to the groove plate cover again, so that the groove plate cover restores and flattens the surface of the door frame groove, effectively reducing the impact of the door frame groove on the travel of the flexible door, and the flat door frame groove avoids the retention of dust and debris, effectively reducing the cleaning work of the flexible door.

[0030] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1 to Figure 2It is shown that a flexible door for shipyard with flame retardant function comprises a door frame 1, a door curtain 101 is fixedly connected to the top of the door frame 1, a door curtain beam 2 is fixedly connected to the bottom of the door curtain 101, a door frame groove 3 is fixedly connected to the bottom of the door frame 1, and the door curtain beam 2 is correspondingly connected to the door frame groove 3;

[0033] When the flexible door is closed, the door curtain beam 2 descends into the door frame groove 3, so that the door curtain beam 2 is snap-fitted with the door frame groove 3, effectively improving the sealing and flame-retardant effect between the flexible door and the ground, and preventing the spread of fire.

[0034] Figures 2 to 5 As shown, a slot plate cover 301 is movably connected to the top of the door frame slot 3, the slot plate cover 301 corresponds vertically to the door curtain crossbeam 2, and the upper surface of the slot plate cover 301 is flush with the upper surface of the door frame slot 3, and a plurality of support holes 302 are equidistantly provided on the surface of the slot plate cover 301, and a rotating column 303 is rotatably connected to the support hole 302 in the middle of the door frame slot 3, the top of the rotating column 303 is plugged into the support hole 302, and a support block 304 is fixedly connected to the top of the rotating column 303, and the support block 304 contacts the lower opening of the support hole 302, and a through slot 305 is provided on the edge of the support hole 302, and the through slot 305 corresponds in shape to the support block 304, and a limit stopper 306 is fixedly connected to the upper edge of the door frame slot 3 at an equidistant distance, and the limit stopper 306 Corresponding to the top edge of the slot plate cover 301, a cover plate spring 307 is fixedly connected between the bottom of the slot plate cover 301 and the middle of the door frame slot 3. The maximum rising height of the slot plate cover 301 is limited by the limit stop 306, so as to achieve the flush effect of the slot plate cover 301 and the upper opening of the door frame slot 3, and at the same time, it is convenient to install multiple groups of slot plate covers 301 on the door frame slot 3 to adapt to the door frame slot 3 with a longer length. The bottom of the rotating column 303 is fixedly connected with a base plate 308, and the two ends of the base plate 308 are fixedly connected to the inner wall of the door frame slot 3 with a return spring 309. The elastic force of the return spring 309 is used to pull the base plate 308 to realize the rotation recovery of the rotating column 303, that is, the rotating column 303 is restored to the state of supporting the slot plate cover 301.

[0035] The upper opening of the door frame slot 3 is paved and covered by the slot plate cover 301, so that the door frame slot 3 is flush with the ground when it is not combined with the door curtain beam 2, that is, when the flexible door is in an open state, the door frame slot 3 flush with the ground effectively prevents dust and debris from staying at the bottom of the flexible door, and facilitates the entry and exit of the flexible door. The support block 304 on the rotating column 303 is used to contact the lower opening of the support hole 302 to support the slot plate cover 301, effectively improving the compressive strength of the slot plate cover 301. When the door curtain beam 2 leaves the door frame slot 3, the cover plate spring 307 uses its own elastic force to push the slot plate cover 301 up, and at the same time uses the limit stopper 306 to The maximum rising height of the cover 301 is limited, and the blocking of the slot cover 301 by the limit stop 306 is mainly used for flexible doors with large spans. Flexible doors with large spans require a longer length of the door frame slot 3, so it is necessary to install multiple sections of slot cover 301 to cover the door frame slot 3 in sections. For flexible doors with shorter spans, only one section of slot cover 301 needs to be installed to cover the door frame slot 3. The maximum rising height can be directly limited at both ends of the slot cover 301 through the door frame body 1. The cover spring 307 can also use its own elastic force to provide buffering capacity for the slot cover 301. The buffer zone is in the gap between the support block 304 and the slot cover 301.

[0036] Figures 4 to 7 As shown, the interior of the door curtain crossbeam 2 corresponds to the rotating pipe column 303 and is fixedly connected with a fixing cylinder 201, the interior of the fixing cylinder 201 is rotatably connected with a rotating bolt 202, the rotating bolt 202 is plugged with the rotating pipe column 303, the top of the fixing cylinder 201 is slidably connected with a linkage bracket 203, the linkage bracket 203 is hinged to the top of the rotating bolt 202, and a pushing cylinder 204 is hinged between the linkage bracket 203 and the door curtain crossbeam 2, the internal shape of the fixing cylinder 201 corresponds to the combination of the supporting hole 302 and the through groove 305, and the interior of the fixing cylinder 201 is movably connected with a straightening cover 205, and the straightening cover 205 is sleeved with the rotating bolt 202, so that the rotating pipe column 303 can directly enter the fixing cylinder 201 after extending out of the supporting hole 302. The fixed cylinder 201 is fixed, and the specific shape of the fixed cylinder 201 is used to limit the support block 304 to prevent the rotating column 303 from restoring and rotating during the process of entering the fixed cylinder 201. The straightening cover 205 is used to provide auxiliary support for the rotating bolt 202, which effectively improves the stability of the rotating bolt 202 in an idle state. The top of the fixed cylinder 201 is provided with a rotary lock opening 206, and the rotary lock opening 206 corresponds to the support block 304. The lower surface of the straightening cover 205 corresponds to the rotary lock opening 206. When the rotating column 303 extends to the top of the fixed cylinder 201, the rotating column 303 performs a restoring rotation, allowing the support block 304 to rotate and snap into the rotary lock opening 206, thereby effectively improving the stable locking effect of the door curtain beam 2 and the door frame groove 3;

[0037] When the flexible door is closed, before the curtain beam 2 descends and enters the door frame slot 3, the rotating bolt 202 is first inserted into the rotating column 303, and the linkage bracket 203 is pushed by the pushing cylinder 204, so that the rotating bolt 202 drives the rotating column 303 to rotate, so that the support block 304 rotates to the bottom of the through slot 305, and the curtain beam 2 continues to descend and presses the slot cover 301 to sink, that is, the curtain beam 2 is engaged with the door frame slot 3, and the rotating column 303 extends out of the supporting hole 302 and enters the fixed cylinder 201. The special shape inside the fixed cylinder 201, that is, the combined shape of the supporting hole 302 and the through slot 305, restricts the rotating column 303 from restoring rotation in shape. After the rotating column 303 extends to the top of the fixed cylinder 201, the rotating column 303 is restored and rotated, allowing the support block 304 to rotate and snap into the rotary lock mouth 206, thereby effectively improving the stable locking effect of the curtain beam 2 and the door frame slot 3.

[0038] The second implementation method:

[0039] Compared with the first embodiment, this embodiment mainly adds a water flow channel 4. The specific newly added structure is as follows, and the remaining structures are consistent with the first embodiment.

[0040] Figure 2 and Figure 8 As shown, the bottom of the door frame groove 3 is fixedly connected with a water flow groove 4, which corresponds to the door frame groove 3 coaxially, and the water flow groove 4 corresponds to the through groove 305 vertically, and the dust and debris falling from the through groove 305 directly fall into the water flow groove 4, and the dust and debris are taken out by the water flow in the water flow groove 4, which effectively improves the self-cleaning effect of the door frame groove 3, and one end of the door frame groove 3 is rotatably connected with a water blocking gate 401, and the bottom of the water blocking gate 401 corresponds to the water flow groove 4, and the water flow of the water flow groove 4 is intercepted by the water blocking gate 401, so that the water flow fills the door frame groove 3, and the door curtain beam 2 is immersed in water, thereby effectively improving the fire prevention and cooling ability of the door curtain beam 2;

[0041] When the flexible door is in the open state, personnel and equipment enter and exit the flexible door with a small amount of dust and debris, and some of the dust and debris may fall from the through groove 305 into the door frame groove 3. The dust and debris falling from the through groove 305 into the door frame groove 3 directly fall into the water flow groove 4, and the dust and debris are directly cleaned up by the water flow in the water flow groove 4. In the event of a fire, when the flexible door is closed for flame retardant isolation, the water-blocking gate 401 is lowered to store water in the door frame groove 3, and the full water submerges the door curtain beam 2 connected in the door frame groove 3, thereby effectively improving the fire prevention and cooling capacity of the door curtain beam 2.

[0042] Figure 5 , Figure 6 , Figure 8 and Fig. 9As shown, the interior of the door curtain crossbeam 2 is fixedly connected with a water-absorbing cotton block 402, and the top of the water-absorbing cotton block 402 is fixedly connected with an infiltration cover edge 403, and the water-absorbing cotton block 402 and the infiltration cover edge 403 are both made of sponge material, and the water absorption capacity of the water-absorbing cotton block 402 and the infiltration cover edge 403 is used to achieve water drainage. In rainy days, the water outside the door frame groove 3 can be drained into the water flow trough 4 for discharge. In the event of a fire, the door frame groove 3 is filled with water, and the water in the door frame groove 3 is drained out through the water-absorbing cotton block 402 and the infiltration cover edge 403, so that the door frame groove 3 is in a humid state, thereby effectively improving the fire retardant effect, the bottom of the infiltration cover edge 403 is in contact with the outer edge of the door frame groove 3, and a lead-out groove 404 is provided on the bottom surface of the infiltration cover edge 403, and the water absorption and water seepage effect of the infiltration cover edge 403 is effectively improved by providing the lead-out groove 404;

[0043] In a rainy environment, when the flexible door is still in a closed state, the water outside the door frame groove 3 is absorbed by the seepage cover edge 403, and is guided into the door frame groove 3 through the absorbent cotton block 402, and finally discharged from the water flow channel 4, effectively preventing rainwater from seeping into the flexible door in rainy days. On the contrary, in the event of a fire, the water-blocking gate 401 is lowered to fill the door frame groove 3 with water, and the absorbent cotton block 402 is immersed in the water. The water absorption capacity of the absorbent cotton block 402 and the seepage cover edge 403 is utilized to guide water to seep out of the seepage cover edge 403, thereby keeping the door frame groove 3 area in a moist state, further effectively improving the fire retardant effect of the flexible door.

[0044] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
