[0002] The present invention relates to the technical field related to escalators, and more precisely, to updated escalators.

Background Art

[0003] An escalator is a power device widely used in public places. An escalator consists of members such as a truss, steps, step guide rails, step chains, a hoist, a skirt guard, inner and outer cover plates, a handrail system, an electric control system, etc. Here, most members are mounted in combination with the truss, and the truss serves as a support and plays a supporting role. It is the basic member of the escalator and also the member with the largest volume and weight among the escalators.

[0004] Conventional escalators are generally designed simultaneously with the building and installed according to the building. Generally, the upper and lower ends of the original truss are embedded in different floors of the building. When updating and replacing an escalator, it is necessary to install a new escalator after removing all of the original escalator. However, it is difficult to remove the original truss, and it is easy to damage the building. The update is time-consuming and costly.

[0005] Thus, there is a need in the art for an escalator that can be updated and replaced with the original truss so as to improve the efficiency of updating and replacing the escalator and reduce costs.

Embodiments for Carrying out the Invention

[0025] Hereinafter, in combination with the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained on the premise that those skilled in the art do not perform creative labor belong to the protection scope of the present invention.

[0026] As shown in FIG. 1, the original truss 10 of the original escalator after removing other members has a lower part 101, a middle part 102, and an upper part 103. The lower part 101 and the upper part 103 are parallel and held horizontally. Moreover, the lower part 101 and the upper part 103 are respectively connected to different floors, and the middle part 102 is inclined and located between the lower part 101 and the upper part 103. The boundaries between the middle part 102 and the lower part 101 and the upper part 103 respectively have bending and turning segments. The middle part 102 of the original truss 10 has several horizontal bars 11 distributed in parallel.

[0027] As shown in FIG. 2, the updated escalator of the present application includes a truss unit and several escalator members implemented in combination with the truss unit. The escalator members include steps, step guide rails, step chains, hoisting machines, skirt guards, inner and outer cover plates, handrail systems, electric control systems, etc. The truss unit includes a lower machine room 21, a lower turning segment 22, at least one group of flat intermediate segments, an upper turning segment 24, and an upper machine room 25. The widths of the lower machine room 21, the lower turning segment 22, the intermediate segment group, the upper turning segment 24, and the upper machine room 25 are all smaller than the internal width of the original truss 10. Moreover, the height of the flat intermediate segment group is close to or equal to the distance from the top margin of the original truss to the cross bar 11. That is, the intermediate segment group can be inserted into the original truss 10 without being obstructed by the cross bar 11. The length of the intermediate segment group is greater than or equal to the distance between two adjacent cross bars 11. The lower machine room 21, the lower turning segment 22, the intermediate segment group, the upper turning segment 24, and the upper machine room 25 are respectively inserted into the corresponding positions of the original truss 10 and avoid the cross bar 11 at the corresponding positions, and then the escalator members are further implemented. By adopting the above updated escalator, the update can be completed without removing the original truss, the strength of the original truss can be completely maintained, the update is more convenient and efficient, and the cost can be lower without damaging the building.

[0028] Specifically, the lower machine room 21 is inserted into the lower part 101, the lower turning segment 22 is inserted into the boundary between the lower part 101 and the middle part 102, the intermediate segment group is inserted into the middle part 102, the upper turning segment 24 is inserted into the boundary between the middle part 102 and the upper part 103, and the upper machine room 25 is inserted into the upper part 103. In order to improve the strength of the truss unit, it may be provided that the adjacent lower machine room 21, lower turning segment 22, intermediate segment group, upper turning segment 24, and upper machine room 25 are connected by a bolt or screw structure.

[0029] Referring to FIG. 3, the intermediate segment group is composed end-to-end of a plurality of intermediate segments 23. The intermediate segment 23 includes an upper flat body 230. The upper flat body 230 has several sets of upright rods 233. The upright rods 233 extend from the bottom of the upper flat body 230 to form an extending structure. The bottom ends of each set of extending structures are connected to each other by a bottom horizontal rod 2331. There is a vertical opening region with a gap between each set of extending structures and facing downward. The upper flat bodies 230 of each intermediate segment 23 form the intermediate segment group end-to-end. The upper flat body 230 is located above the cross bar 11, and the extending structure is located between the cross bars 11, and can effectively avoid the cross bar 11.

[0030] To improve the structural stability of the intermediate segment 23, it is preferable to install several supplementary chord members 2332 and diagonal tension rods 2333 between the extending structures. Referring to FIGS. 4 and 5, the length L1 of the intermediate segment 23 may be greater than the spacing distance L between adjacent cross bars 11. When the intermediate segment 23 is inserted into the original truss, the upper flat body 230 is placed on the upper surface of the cross bar 11, the extending structure is inserted into the spacing position between the cross bars 11, and the opening region avoids the cross bar 11. Increasing the length of the intermediate segment 23 can reduce the number of intermediate segments, further improve the implementation accuracy of escalator updates, reduce the workload, and improve work efficiency.

[0031] Specifically, referring to FIGS. 5A and 6, the upper flat body 230 is formed into a rectangular structure by upper vertical rods 231 on both upper sides, lower vertical rods 232 on both lower sides, several upright rods 233, and several middle horizontal rods 234. Each set of upright rods 233 forms a rectangular extending structure with the corresponding middle horizontal rod 234 and the bottom horizontal rod 2331. The upper flat body 230 and the extending structure are an integral structure and have good stability. The intermediate segment 23 has a certain vertical and horizontal stability and can withstand vertical and horizontal loads at the same time.

[0032] Both upper ends of the middle segment 23 each have two sets of upper connection seats 235, and both sides of both lower ends of the middle segment 23 each have two sets of lower connection seats 236. The connection between the middle segments 23 is realized by the coupling of the upper connection seats 235 and the lower connection seats 236 with the bolt assembly. The middle segments 23 located at both ends of the middle segment group are respectively connected to the lower turning segment 22 and the upper turning segment 24 by the coupling of the upper connection seats 235, the lower connection seats 236 and the bolt assembly.

[0033] One end of the diagonal pull rod 2333 is connected to the boundary between the upright rod 233 and the upper longitudinal rod 232, and the other end is connected to the lower connection seat 236 or the adjacent area of the adjacent upright rod 233. The inclination direction of the diagonal pull rod 2333 is set according to the direction of the force applied after the middle segment 23 is inserted and installed.

[0034] Furthermore, referring to FIG. 5B, the upright rod 233 does not have to protrude from the bottom of the upper flat body 230. The bottom of the upright rod 233 is connected to the extending rod 233A extending downward to form an extending structure. The extending rod 233A can be connected to the upright rod 233 by a welding method or a method of being connected by fastening parts. Alternatively, the bottom of the upper flat body 230 is connected to the displacement rod 233B whose position other than the upright rod 233 extends downward to form an extending structure. The displacement rod 233B can be connected to the upper flat body 230 by a welding method or a method of being connected by fastening parts. The extending structure in the above form is provided more flexibly and can better adapt to different positions of the cross bar 11. Furthermore, an auxiliary connection unit is coupled and installed between the extending structures. The auxiliary connection unit includes a bottom end link 301 passing through the bottom ends of some extending structures and some auxiliary diagonal pull rods 302 whose both ends are respectively connected to two adjacent extending structures. It is preferable that the auxiliary diagonal pull rod 302 has an auxiliary tensoner 303.
