[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] Example 1

[0025] like Figure 1 — Figure 2 As shown, a large-span arch-supported escalator of the present invention includes a left hoistway platform 100, a right hoistway platform 200, a truss 300, an arch frame 400 and a connecting rod 500.

[0026] A right hoistway platform 200 is provided on one side of the left hoistway platform 100, a truss 300 is installed between the left hoistway platform 100 and the right hoistway platform 200, an arch frame 400 is provided between the left hoistway platform 100 and the right hoistway platform 200, the arch frame 400 and the truss 300 are connected by a plurality of connecting rods 500, one end of the arch frame 400 is connected to the left hoistway platform 100, and the other end of the arch frame 400 is connected to the right hoistway platform 200. The arrangement of the arch frame 400 effectively improves the stability of the escalator, so that the escalator can be applied to environments such as rivers; further, the two ends of the arch frame 400 are respectively installed on the left hoistway platform 100 and the right hoistway platform 200, so, The two ends of the arch frame 400 will not interfere with the two ends of the truss 300, which also allows the equipment located at both ends of the truss 300 to be installed smoothly; in addition, after the arch frame 400 and the truss 300 are connected together, the arch frame 400 and the truss 300 will form a whole, and the two ends of the truss 300 are now connected to the left hoistway platform 100 and the right hoistway platform 200 respectively. At the same time, the two ends of the arch frame 400 are connected to the left hoistway platform 100 and the right hoistway platform 200 respectively. In this way, the contact area between the entire escalator and the left hoistway platform 100 and the right hoistway platform 200 can be effectively increased, thereby increasing the supporting area of the left hoistway platform 100 and the right hoistway platform 200 for the escalator, thereby making the entire escalator more stable.

[0027] A mounting plate 410 is provided at the end of the arch frame 400, and the bottom surface of the mounting plate 410 is in contact with the left hoistway platform 100 or the right hoistway platform 200. The mounting plate 410 is provided with at least two fixing bolts 420 connected to the left hoistway platform 100 or the right hoistway platform 200. During installation, people need to place one mounting plate 410 on the left hoistway platform 100 and the other mounting plate 410 on the right hoistway platform 200, and connect the two mounting plates 410 to the corresponding left hoistway platform 100 or the right hoistway platform 200 through the fixing bolts 420, so that the arch frame 400 can be stably installed between the left hoistway platform 100 and the right hoistway platform 200.

[0028] A steel plate 310 is connected to the side surface of the top of the truss 300, and each of the connecting rods 500 passes through the steel plate 310. A nut 510 is connected to the bottom end of the connecting rod 500, and the nut 510 is pressed against the steel plate 310. The cross-section of the steel plate 310 is an inverted L-shape. The steel plate 310 and the truss 300 are connected by multiple connecting bolts 320. When the truss 300 falls due to its own gravity, the steel plate 310 and the truss 300 are connected by multiple connecting bolts 320, so that the steel plate 310 will also deform as the truss 300 falls. At this time, the connecting rod 500 will drag the steel plate 310 through the nut 510. In this way, the connecting rod 500 will drag the entire truss 300 to improve the stability of the truss 300 during use.

[0029] Example 2

[0030] like Figure 3 — Figure 5 As shown, the difference between this embodiment and the first embodiment is that the structure of the connecting rod 500 is changed in this embodiment.

[0031] Specifically, the connecting rod 500 includes an upper rod body 520 connected to the arch frame 400 and a lower rod body 530 connected to the truss 300. The upper rod body 520 and the lower rod body 530 are connected by a connecting sleeve 540. During the installation process, people need to connect the upper rod body 520 to the arch frame 400 and connect the lower rod body 530 to the steel plate 310 on the truss 300. After that, the upper rod body 520 and the lower rod body 530 need to be connected together through the connecting sleeve 540. In this way, the connection between the arch frame 400 and the truss 300 can be achieved.

[0032] Furthermore, an upper connecting column 521 is provided on one end of the upper rod 520 away from the arch frame 400, and a lower connecting column 531 is provided on one end of the lower rod 530 away from the truss 300. The cross-sectional shape of the upper connecting column 521 and the lower connecting column 531 after being spliced is the same as the cross-sectional shape of the upper rod 520 or the lower rod 530. Specifically, the cross-sectional shape of the upper rod 520 is the same as the cross-sectional shape of the lower rod 530, and the cross-sectional shape of the upper connecting column 521 is the same as the cross-sectional shape of the lower connecting column 531. The cross-sectional shape of the upper rod body 520 is circular, and the cross-sectional shape of the upper connecting column 521 is semicircular. During the assembly of the upper rod body 520 and the lower rod body 530, people need to stick the side of the upper connecting column 521 facing the lower connecting column 531 to the side of the lower connecting column 531 facing the upper connecting column 521. After that, people can install the connecting sleeve 540 on the upper connecting column 521 and the lower connecting column 531 to ensure that the upper rod body 520 and the lower rod body 530 can be stably connected.

[0033] The lower connecting post 531 is provided with a plurality of clips 521a on the side facing the lower connecting post 531, and the upper connecting post 521 is provided with a slot 531a corresponding to the clips 521a on the side facing the lower connecting post 531. When the side of the upper connecting post 521 facing the lower connecting post 531 is attached to the side of the lower connecting post 531 facing the upper connecting post 521, each clip 521a is inserted into the corresponding slot 531a, so that after the connecting sleeve 540 is installed on the upper connecting post 521 and the lower connecting post 531, the upper connecting post 521 will not be dislocated relative to the lower connecting post 531. This ensures that the upper rod body 520 and the lower rod body 530 can be stably connected, which not only makes it convenient for people to connect the truss 300 and the arch frame 400 together, but also makes it convenient for people to transport the connecting rod 500; in addition, people can appropriately adjust the connection position between the upper connecting column 521 and the lower connecting column 531 according to the spacing between the arch frame and the truss 300, and ensure that at least two clips 521a are inserted into the slot 531a, so that the assembled connecting rod 500 can be suitable for different spacings between the arch frame 400 and the truss 300.

[0034] The outer side surface of the upper connecting column 521 and the outer side surface of the lower connecting column 531 are both provided with external threads 550, and the connecting sleeve 540 is provided with an internal thread 541 corresponding to the external thread 550. When the connecting sleeve 540 is sleeved on the outer surfaces of the upper connecting column 521 and the lower connecting column 531, the connecting sleeve 540 can be stably installed on the outer surfaces of the upper connecting column 521 and the lower connecting column 531 through the action of the internal thread 541 and the external thread 550; furthermore, the spacing between two adjacent clips 521a is the same as the pitch of the external thread 550. Therefore, when the upper connecting column 521 and the lower connecting column 531 move relative to each other by a spacing, the upper connecting column 521 and the lower connecting column 531 will also move relative to each other by a pitch at the same time. Therefore, the internal thread 541 in the connecting sleeve 540 can still connect to the external thread 550.

[0035] A plurality of lighting lamps 430 are provided on the arch frame 400. The lighting lamps 430 are provided to make
