Detailed implementation manners

[0031] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation manners.

[0032] In the present invention, unless otherwise clearly specified and defined, the first feature being “above” or “below” the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being “above” the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being “below” the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is less than that of the second feature.

[0033] As Figures 1 to 4 shown, the elevator fire door of an embodiment includes a door leaf 1, and the door leaf 1 includes a first door leaf 11 and a second door leaf 12. The first door leaf 11 includes a first heat insulation board 111, a second heat insulation board 112, a filling material 113, and a plurality of reinforcing members 114. The first heat insulation board 111 is parallel to the second heat insulation board 112. The reinforcing members 114 are arranged between the first heat insulation board 111 and the second heat insulation board 112, and both sides of the reinforcing members 114 are respectively connected to the first heat insulation board 111 and the second heat insulation board 112. The filling material 113 is arranged in the gap between the first heat insulation board 111 and the second heat insulation board 112.

[0034] Both sides of the first door leaf 11 of the elevator fire door of this embodiment are respectively the first heat insulation board 111 and the second heat insulation board 112, which can effectively block the transfer of high temperature. The filling material 113 between the first heat insulation board 111 and the second heat insulation board 112 can further enhance the fireproof and heat insulation function of the first door leaf 11. Since there are also reinforcing members 114 between the first heat insulation board 111 and the second heat insulation board 112, the first heat insulation board 111 and the second heat insulation board 112 are not easily deformed when heated, and can maintain the original shape of the first door leaf 11, with good fireproof performance.

[0035] The second door leaf 12 also adopts the same sandwich structure as the first door leaf 11, and also has excellent fireproof and heat insulation performance, which will not be elaborated here.

[0036] The embodiment of the present invention also provides a ship, including a plurality of elevators, and such elevators include the elevator fire doors of the above embodiment, making the ship highly safe.

[0037] As Figure 4As shown, further, the reinforcing member 114 is in a U-shaped groove form, including a bottom plate 1141 and two side plates 1142. The side plates 1142 are connected to the bottom plate 1141, and the two side plates 1142 are oppositely arranged on both sides of the bottom plate 1141. The side plates 1142 are connected to the first door leaf 11 or the second door leaf 12. The side plates 1142 have a relatively large contact area with the first door leaf 11 or the second door leaf 12, which can provide good support for the first door leaf 11 or the second door leaf 12, effectively preventing the first door leaf 11 or the second door leaf 12 from deforming due to heat. The filling material 113 can also provide a limiting effect on the reinforcing member 114, avoiding displacement of the reinforcing member 114. The reinforcing member 114 does not need to be connected to the first door leaf 11 or the second door leaf 12 by means such as welding. The filling material 113 can be selected from rock wool or other types of fire-resistant and heat-insulating materials.

[0038] As Figure 2 and Figure 5 As shown, the elevator fire door of this embodiment further includes a sill 2, a first seal 31, a sill sealing plate 41, and a slider 5. The sill 2 is provided with a first chute 100 and a second chute 200. The first chute 100 is parallel to the second chute 200. The first seal 31 is arranged at the bottom of the first chute 100. The slider 5 and the sill sealing plate 41 are arranged at the bottom of the door leaf 1. One end of the sill sealing plate 41 away from the door leaf 1 is inserted into the first chute 100. The sill sealing plate 41 and the first seal 31 are arranged at intervals. The slider 5 is inserted into the second chute 200. The slider 5 inserted into the second chute 200 is used to realize the smooth movement of the door leaf 1. When a fire occurs, the first seal 31 will expand due to heat. The expanded first seal 31 contacts the sill sealing plate 41 to seal the first chute 100, playing a role in blocking flames or smoke and preventing flames or smoke from invading the elevator shaft.

[0039] As Figure 6As shown in the figure, further, the sill 2 includes a first bending member 21 and a second bending member 22. The end faces of the first bending member 21 and the second bending member 22 are both in a U-shape. The first bending member 21 includes a first horizontal plate 211, two first vertical plates 212 and two second horizontal plates 213. The two first vertical plates 212 are oppositely arranged on both sides of the first horizontal plate 211. A first groove is formed between the two first vertical plates 212. The second horizontal plate 213 is parallel to the first horizontal plate 211. One side of the second horizontal plate 213 is connected to the end of the first vertical plate 212 away from the first horizontal plate 211. The second bending member 22 includes a third horizontal plate 221, two second vertical plates 222, a fourth horizontal plate 223 and a fifth horizontal plate 224. The two second vertical plates 222 are oppositely arranged on both sides of the third horizontal plate 221. A second groove is formed between the two second vertical plates 222. The fourth horizontal plate 223 and the fifth horizontal plate 224 are both parallel to the third horizontal plate 221. One side of the fourth horizontal plate 223 and the fifth horizontal plate 224 are respectively connected to the end of a second vertical plate 222 away from the third horizontal plate 221. The second bending member 22 is arranged in the first groove. The fourth horizontal plate 223 and the fifth horizontal plate 224 are both connected to the first horizontal plate 211. A first sliding groove 100 or a second sliding groove 200 is formed between the first vertical plate 212 and the second vertical plate 222.

[0040] For the sill 2 with this structure, only two plates need to be bent into a U-shape respectively to obtain the first bending member 21 and the second bending member 22, and then the smaller second bending member 22 is placed into the first bending member 21 to obtain the first sliding groove 100 and the second sliding groove 200. The manufacturing cost is low and the weight is light. The fourth horizontal plate 223 and the fifth horizontal plate 224 both have a large contact area with the first horizontal plate 211. The fourth horizontal plate 223 and the fifth horizontal plate 224 can be welded to the first horizontal plate 211 to stably fix the second bending member 22 in the first bending member 21.

[0041] Furthermore, the second horizontal plate 213 is flush with the third horizontal plate 221. When the door leaf 1 is opened, the sill 2 may be stepped on. In order to avoid people from tripping, the surface of the sill 2 needs to be kept flat. Therefore, the second horizontal plate 213 and the third horizontal plate 221 should be at the same height.

[0042] Such as Figure 5As shown, the slider 5 is located above the fourth cross plate 223, the sill sealing plate 41 is located above the fifth cross plate 224, and the width of the fifth cross plate 224 is smaller than that of the fourth cross plate 223. In order to achieve a better sealing effect, the width of the first chute 100 should be set narrower to provide the limited space to the second chute 200, so that the size of the slider 5 can be set larger to ensure the strength of the slider 5 and make it not easily deformed. In this embodiment, the sill 2 further includes a third bending member 23, a fourth bending member 24, and a fifth bending member 25. The horizontally arranged part of the third bending member 23 serves as the base of the first bending member 21 and the fourth bending member 24. In addition, when the second cross plate 213 on the outer side is stepped on, the vertically arranged part of the third bending member 23 can also support the second cross plate 213. The fourth bending member 24 is filled with a refractory and heat-insulating material to improve the fire resistance of the sill 2. The fifth bending member 25 is fixed to one side of the fourth bending member 24, and the fifth bending member 25 can provide a supporting effect for the second cross plate 213 on the inner side.

[0043] As Figure 7 shown, the elevator fire door of this embodiment further includes a lintel sealing structure. The lintel sealing structure includes a first mounting seat 6, a second seal 32, and a lintel sealing plate 42. The first mounting seat 6 is provided with a first mounting groove, the first mounting groove is horizontally arranged, the second seal 32 is arranged in the first mounting groove, the lintel sealing plate 42 is arranged on the top of the door leaf 1, and the lintel sealing plate 42 includes a first horizontal sealing plate 421, a first vertical sealing plate 422, a second horizontal sealing plate 423, and a second vertical sealing plate 424. The two sides of the first vertical sealing plate 422 are respectively connected to the first horizontal sealing plate 421 and the second horizontal sealing plate 423. The first horizontal sealing plate 421 and the second horizontal sealing plate 423 are located on different sides of the first vertical sealing plate 422. The second vertical sealing plate 424 is connected to the side of the second horizontal sealing plate 423 away from the first vertical sealing plate 422, and the second vertical sealing plate 424 extends in the direction of the first horizontal sealing plate 421. The second seal 32 is arranged opposite to the first vertical sealing plate 422. The second horizontal sealing plate 423 is located above the first mounting seat 6, and the second vertical sealing plate 424 is located on the side of the first mounting seat 6 away from the first vertical sealing plate 422. A labyrinth-like bending space is formed between the first mounting seat 6 and the lintel sealing plate 42. This labyrinth-like bending space can increase the difficulty of the intrusion of flames or smoke. When a fire occurs outside the door leaf 1, since the second seal 32 faces the door leaf 1, the second seal 32 will quickly heat up and expand. After expansion, the second seal 32 is in contact with the first vertical sealing plate 422, sealing the channel between the first mounting seat 6 and the lintel sealing plate 42 and blocking the intrusion of flames or smoke into the elevator shaft.

[0044] As Figure 8As shown in the figure, the elevator fire door of this embodiment further includes a door pocket sealing structure. The door pocket sealing structure includes a second mounting seat 7, a third seal 33, and a door pocket sealing plate 43. A second mounting groove is provided on the second mounting seat 7. The second mounting groove is vertically arranged. The third seal 33 is arranged in the second mounting groove. The third seal 33 faces the door leaf 1. The door pocket sealing plate 43 is arranged on the side of the door leaf 1. The door pocket sealing plate 43 includes a third vertical sealing plate 431 and a fourth vertical sealing plate 432 that are perpendicularly connected to each other. The third vertical sealing plate 431 is fixed to the side of the door leaf 1. The third vertical sealing plate 431 is perpendicular to the moving direction of the door leaf 1 and is spaced from the second mounting seat 7. The fourth vertical sealing plate 432 is parallel to the moving direction of the door leaf 1. The fourth vertical sealing plate 432 is located on the side of the second mounting seat 7 away from the door leaf 1. A labyrinth-like channel is also formed between the second mounting seat 7 and the door pocket sealing plate 43. When a fire occurs, the third seal 33 can expand due to heat. The expanded third seal 33 abuts against the door leaf 1, so that the channel between the second mounting seat 7 and the door pocket sealing plate 43 is sealed, blocking the intrusion of flames or smoke.

[0045] As Figure 9 shown, on the side of the first door leaf 11 close to the second door leaf 12, a receiving groove 300 is provided. A fourth seal 34 is provided at the bottom of the receiving groove 300. On the side of the second door leaf 12 close to the first door leaf 11, a protruding structure 121 is formed. The protruding structure 121 can be inserted into the receiving groove 300 and abut against the fourth seal 34. When the door leaf 1 is in the closed state, the protruding structure 121 abuts against the fourth seal 34, achieving a good sealing effect. When a fire occurs, the fourth seal 34 expands due to heat, further enhancing the sealing performance between the first door leaf 11 and the second door leaf 12, blocking the entry of flames or smoke into the elevator shaft.
