[0006] A further improvement of the suspended push-pull protective sealed blocking door of the utility model is that a limiting plate is provided on the first side of the blocking plate, and a blocking block for blocking the limiting plate adjacent to the blocking plate is provided on the second side of the blocking plate.

[0007] A further improvement of the suspended push-pull protective sealed blocking door of the utility model is that the cross section of the lower track is U-shaped, and the distance between the two flange plates of the lower track is not less than the thickness of the blocking plate.

[0008] The utility model is further improved by the suspended push-pull protective sealed blocking door in that the suspension member comprises a roller matched with the upper track, a connecting plate connected to the roller, and a rotating bearing rotatably connected between the connecting plate and the blocking plate.

[0009] The utility model is further improved by the suspended push-pull protective sealed blocking door in that the built-in lock includes an external driving member, a locking rod vertically slidably installed on the blocking plate, and a transmission mechanism connected between the external driving member and the locking rod, the blocking plate is provided with an exit hole for the locking rod to pass through, and the upper track is provided with a lock hole for the locking rod to pass through.

[0010] Compared with the prior art, the utility model has a positive and obvious effect. The utility model installs multiple blocking plates in a slidable and rotatable manner.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 10 As shown, the utility model provides a suspended push-pull protective sealed blocking door, comprising: a track assembly, the track assembly comprising an upper track 2 for installation above a tunnel entrance 1 and a lower track 3 for installation below the tunnel entrance 1, one end of the upper track 2 extends out of the tunnel entrance 1 to form an extension section, and the length of the lower track 3 is the same as the width of the tunnel entrance 1; a plurality of hanging members 5 slidably mounted on the upper track 2; a plurality of blocking plates 4 for blocking the tunnel entrance 1, the upper ends of the plurality of blocking plates 4 are rotatably connected to the plurality of the hanging members 5 in a one-to-one correspondence, the lower ends of the blocking plates 4 are slidably limited in the lower track 3, and a accommodating space is provided below the extension section for accommodating all the blocking plates 4 in a width direction perpendicular to a length direction of the upper track 2; and a built-in lock for fixing the position of the blocking door. The utility model can realize the blocking of the tunnel entrance 1 by the blocking plate 4 through the upper track 2 and the lower track 3. The width of all the blocking plates 4 after docking should be greater than the width of the tunnel entrance 1. The blocking plates 4 can be rotated 360 degrees through the hanging parts 5. Therefore, when opening the tunnel entrance 1, all the blocking doors are moved to the extension section position through the upper track 2 and rotated 90 degrees, so that all the blocking plates 4 are stored in the accommodating space. The accommodating space can be reserved in advance during tunnel construction, thereby saving space for the storage of tunnel protection doors and avoiding affecting the passage of the tunnel entrance 1.

[0024] Preferably, Figure 5 to Figure 7As shown, sealing strips 401 are provided on both sides of the blocking plate 4. Specifically, the blocking plate 4 includes a first panel, a second panel, and a fixed plate fixed between the first panel and the second panel. The fixing plates extend from both sides of the first panel to form a first connecting section, and the fixing plates extend from both sides of the second panel to form a second connecting section. The cross section of the sealing strip 401 is L-shaped, and a plug-in groove for plugging the first connecting section is provided on the first side block of the sealing strip 401. The first side block of the sealing strip 401 is plugged into the first connecting section through the plug-in groove. After the adjacent blocking plates 4 are docked, the ends of the first connecting sections of the adjacent blocking plates 4 are pressed against the first side blocks of the sealing strip 401, and the outer side surfaces of the first connecting sections of the adjacent blocking plates 4 are pressed against the second side blocks of the sealing strip 401, thereby achieving a sealing effect. The sealing strip 401 is arranged along the height direction of the blocking plate 4. The sealing strip 401 can be made of a rubber strip 6 or a silicone strip 6, etc. Further, as Fig.10 As shown, a rubber strip 6 is fixed on the wall around the tunnel opening 1. When the blocking plate 4 is closed at the tunnel opening 1, the blocking plate 4 is tightly attached to the rubber strip 6, thereby achieving an edge sealing effect.

[0025] Preferably, a limiting plate 403 is provided on the first side of the blocking plate 4, and a stopper 402 is provided on the second side of the blocking plate 4 to block the limiting plate 403 of the adjacent blocking plate 4. Specifically, the stopper 402 is fixed to the second connecting section of the second panel close to one side, and the limiting plate 403 is fixed to the second connecting section of the other side and extends out of the second connecting section. When adjacent blocking plates 4 are docked, when the limiting plate 403 abuts against the stopper 402, the end of the first connecting section of the adjacent blocking plate 4 abuts against the first side block of the sealing strip 401, thereby limiting the docking of the blocking plates 4.

[0026] Furthermore, if Figure 1 and Figure 2 As shown, the cross section of the lower track 3 is U-shaped, and the distance between the two flange plates of the lower track 3 is not less than the thickness of the blocking plate 4. Preferably, the distance between the two flange plates of the lower track 3 is slightly greater than the thickness of the blocking plate 4, so as to achieve the deflection of the blocking plate 4 during docking, so that the outer side surface of the first connecting section of the adjacent blocking plate 4 is closely attached to the second side block of the sealing strip 401, and the lower end of the blocking plate 4 is limited at the same time.

[0027] Preferably, Figure 3 and Figure 4As shown, the suspension member 5 includes a roller 504 matched with the upper track 2, a connecting plate connected to the roller 504, and a rotating bearing rotatably connected between the connecting plate and the blocking plate 4. Specifically, the connecting plate can be in a C-shaped or ring-shaped shape to achieve the connection between the inner wall and the roller 504. The upper track 2 can adopt a U-shaped track, and the roller 504 is a roller 504 in the track, and is connected to the inner wall of the connecting plate through a rotating shaft. The upper track 2 can also adopt an I-shaped track, and the roller 504 rolls on both sides of the web, and the roller 504 is a hexagonal wave ball, or an ordinary roller 504, and the ordinary roller 504 is connected to the side wall of the connecting plate through a rotating shaft and the ear plate.

[0028] In this embodiment, the connecting plate includes a U-shaped first mounting plate 501 and a C-shaped second mounting plate 502. Hexagonal beads are fixed to the opposite inner sides of the two flange plates of the first mounting plate 501. At least two hexagonal beads are fixed to each flange plate. The upper track 2 is in an I-shape. The first mounting plate 501 is clamped on both sides of the upper track 2. The hexagonal beads are in contact with the web of the upper track 2. The inner wall of the first flange plate of the second mounting plate 502 is fixed to the outer side of the web of the first mounting plate 501. The second flange plate of the second mounting plate 502 is connected with two strip plates 503. The two strip plates 503 are respectively located on both sides of the second flange plate of the second mounting plate 502 and are rotatably connected through the first pin shaft. The second flange plate of the second mounting plate 502 and the two strip plates 503 are provided with openings for the first pin shaft to pass through. The rotating bearing is a thrust ball bearing. The outer ring of the rotating bearing is fixed to the upper end of the sealing plate 4, and a connecting rod is fixed to the inner ring of the rotating bearing. The connecting rod is connected to the two strip plates 503 through a second pin shaft. Openings for the second pin shaft to pass through are respectively opened on the connecting rod and the two strip plates 503. Fixed plates are respectively fixed on the sides of the two strip plates 503 at the position of the second pin shaft to avoid rotation between the fixing rod and the strip plate 503, thereby ensuring the stability of the sealing plate 4.

[0029] Preferably, Figure 8 and Fig. 9As shown, the built-in lock includes an external drive member 404, a lock rod 410 vertically slidably mounted on the blocking plate 4, and a transmission mechanism that is transmission-connected between the external drive member 404 and the lock rod 410. The blocking plate 4 is provided with an exit hole for the lock rod 410 to pass through, and the upper track 2 is provided with a lock hole for the lock rod 410 to pass through. Specifically, the transmission mechanism is installed inside the blocking plate 4, and includes an intermediate commutator 409, a side commutator 406, a trapezoidal thread sleeve 408, a transverse transmission rod 405 transmission-connected between the intermediate commutator 409 and the side commutator 406, and a vertical transmission rod 407 transmission-connected between the side commutator 406 and the trapezoidal thread sleeve 408. The lock rod 410 is connected to the trapezoidal thread sleeve 408, and an opening for inserting the external drive member 404 is provided on the blocking plate 4 at a position corresponding to the intermediate commutator 409. The external driving member 404 may be a manual hand wheel or an electric driving member 404 .

[0030] Furthermore, there are two side commutators 406, which are respectively located on both sides of the middle commutator 409. There are two transverse transmission rods 405, which are connected to the two side commutators 406 one by one. Each side commutator 406 is respectively connected to a vertical transmission rod 407 on both sides. Each vertical transmission rod 407 is connected to a trapezoidal thread sleeve 408 at one end away from the side commutator 406. Each trapezoidal thread sleeve 408 is connected to a locking rod 410 at one end away from the lateral transmission rod. Locking holes are provided on the upper track 2 for inserting multiple upper locking rods 410 one by one, and insertion holes are provided on the lower track 3 for inserting multiple lower locking rods 410 one by one.

[0031] The external driving member 404 can be inserted into the opening and connected to the middle commutator 409, so that the middle commutator 409 is driven to rotate through the driving member 404. The rotation of the middle commutator 409 drives the side commutator 406 to rotate through the horizontal transmission rod 405. The rotation of the side commutator 406 drives the trapezoidal thread sleeve 408 to rotate through the vertical transmission rod 407. The rotation of the trapezoidal thread sleeve 408 causes the locking rod 410 to extend and retract up and down. The locking rod 410 enters the upper locking hole and the lower insertion hole up and down to achieve locking.

[0032] When closing the tunnel opening 1, the blocking plate 4 is moved to a designated position along the upper track 2 by the hanging member 5. Figure 5 As shown, the blocking plate 4 moves left and right to prepare for close contact, and the limit plate 403 of the blocking plate 4 leans against the stopper 402 to limit the left and right positions, as shown in FIG. Figure 6 As shown, the blocking plate 4 is deflected to a certain extent so that the blocking plate 4 can fully squeeze the sealing strip 401, as shown in FIG. Figure 7As shown, the built-in lock is locked, and the sealing plates 4 fit the rubber strips 6 front and back, producing a sealing effect between adjacent sealing plates 4.

[0033] When opening the tunnel entrance 1, the built-in lock is opened, and the hanging parts 5 are moved piece by piece along the upper track 2 to the accommodation space, and then rotated 90 degrees. Figure 1 As shown, stacking and storage are achieved in the accommodating space.

[0034] The utility model installs multiple blocking plates in a slidable and rotatable manner, and when opening is required, all the blocking plates are stored in the accommodating space, thereby solving the technical problem in the prior art that the door leaf of the tunnel protection door occupies a large space after opening and is inconvenient to store. After being stored, the blocking plates of the utility model do not affect the space of the tunnel entrance at all, thereby not affecting the passage of the tunnel entrance, and ensuring the safety of the passage.

[0035] The parts not involved in the present utility model are the same as the prior art or can be implemented by the prior art. The above is only the preferred embodiment of the present utility model, and does not limit the present utility model in any form. Although the present utility model has been disclosed as the preferred embodiment, it is not used to limit the present utility model. Any technician familiar with this profession can make some changes or modify the technical content disclosed above to an equivalent embodiment of equivalent changes without departing from the scope of the technical solution of the present utility model.
