In some embodiments, the mounting frame 100c of the fire door apparatus 100 is also provided with a shield for fire prevention. For example, an upper frame of the mounting frame 100c is mounted with an upper panel made of a fireproof material, and the vertical height of the upper panel is greater than that of the upper frame, so that the lower side edge of the upper panel extends toward the center of the opening portion after mounting; or, a lower frame of the mounting frame 100c is mounted with a lower protector made of fireproof material, and the vertical height of the lower protector is greater than that of the lower frame, so that the upper side edge of the lower protector extends toward the center of the opening after mounting; or, the upper and lower frames are simultaneously provided with the upper and lower guard plates having the above-mentioned structure, thereby improving the fire prevention effect. Similarly, the left and right frames of the mounting frame 100c may be provided with similar guard plate structures.

In some embodiments, the peripheral edge of the mounting frame 100c is fitted with a flexible seal made of a fire resistant material.

In some embodiments, the middle of the mounting frame 100c is provided with a traveling rail 5 for the transportation vehicle 6 to pass through, the traveling path of the transportation vehicle 6 is formed by the traveling rail 5 penetrating through the opening, and the traveling rail 5, if not optimized, affects the passing performance of the transportation vehicle 6 at the opening, therefore, the traveling rail 5 needs to form an escape part at the closing position of the fire door panel 100a, for example, the traveling rail 5 is cut off to form a gap for the fire door main body 100a to enter between the traveling rails 5, so as to form a complete closed structure for the opening. The width of the avoiding part in the vertical direction of the moving path (such as the gap distance, namely the distance between the traveling rails 5 on both sides of the opening part) is matched with the thickness of the fireproof door panel 100a, so that the transportation vehicle 6 can smoothly pass through the avoiding part.

Since the fire door apparatus 100 is disposed between the fire-proof isolation regions, that is, the walking rails 5 need to be aligned on both sides of the fire door panel 100a, so as to ensure that the transportation vehicle 6 can pass through smoothly, but in the actual installation process, the alignment and installation operation of the walking rails 5 is difficult, long in time, and difficult to maintain and calibrate and maintain in the future; in addition, because the installation degree of difficulty is big, the clearance interval between walking track 5 is difficult to control, and the back of installing usually, clearance interval is great, and the transport vechicle need slow down when passing through the clearance, has reduced automatic material handling system's whole conveying efficiency.

In order to solve the above problem, in some embodiments, as shown in fig. 4 and 5, a first adjusting rail is installed at one end of the first running rail 51 near the gap by a first fixing member, and a second adjusting rail is installed at one end of the second running rail 52 near the gap by a second fixing member, the first fixing member and the second fixing member being configured to adjust a pitch of the gap by adjusting a distance between the first adjusting rail and the second adjusting rail.

The track design with the structure uses two tracks (the first adjusting track 11 and the second adjusting track 12) with shorter lengths to compensate errors caused by track installation, and is convenient for installation and construction, the difficulty of length control and mutual alignment of the first walking track 51 and the second walking track 52 is reduced, and the gap distance can be adjusted through the first fixing part and the second fixing part, so that the adjustment during installation is facilitated, the replacement in the subsequent maintenance process and the calibration of the gap distance size are facilitated, for example, when the service life of the track is longer, the gap distance can be reduced, the closing of the fireproof door panel 100a is influenced, at the moment, the gap distance can be restored by adjusting the track gap (installation distance) between the first adjusting track 11 and the first walking track 51, so that the closing action of the fireproof door panel 100a is smoothly implemented, and similarly, the gap between the second adjusting track 12 and the second walking track 52 can be adjusted, or the gaps between the two groups of adjusting tracks and the walking tracks can be simultaneously adjusted, and the smooth closing of the fireproof door panel 100a is realized. By adopting the track design with the structure, the track installation and maintenance process is simpler and more convenient, the track alignment and the gap spacing are convenient to control, the speed reduction is not needed when the transport vehicle 6 passes through the gap, and the transport efficiency is ensured.

In some embodiments, as shown in fig. 4 and 5, the first moving rail 51 is provided with a first connecting groove, the first adjusting rail 11 is provided with a second connecting groove corresponding to the first connecting groove, and the second connecting groove and the first connecting groove have the same cross-sectional shape and cross-sectional size, the two connecting grooves are fixed to each other by the first connecting member in a clamping manner, so that the first adjusting rail 11 is installed on the first moving rail 51, and the installation distance between the first adjusting rail 11 and the first moving rail 51 can be adjusted by adjusting the clamping depth (or clamping position) of each connecting groove on the first connecting member, where the installation distance refers to the distance of the gap formed between the first adjusting rail 11 and the first moving rail 51.

Similarly, as shown in fig. 4 and 5, the second running rail 52 may also be provided with a third connecting groove similar to the first connecting groove, and the second adjusting rail 12 may also be provided with a fourth connecting groove similar to the second connecting groove, and the third connecting groove and the fourth connecting groove are fixed to each other by a second connecting member in a clamping manner.

Likewise, the first adjustment rail 12 is also provided with the same horizontal running surface and vertical guide surface. The first connecting grooves are provided in two, the first connecting groove being provided on the upper end surface of the vertical guide surface of the first travel rail 51, and the second connecting groove being provided on the side end surface of the horizontal travel surface.
