DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Technical solutions in the embodiments of the present application are clearly and completely described hereinafter in conjunction with the drawings in the embodiments of the present application. Apparently, the embodiments described in the following are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all of the other embodiments which are obtained by those skilled in the art without any creative work fall within the protection scope of the present application.

[0027] As shown in FIG. 3, an original truss 10 of an original escalator with other components removed has a lower portion 101, a middle portion 102 and an upper portion 103, where the lower portion 101 and the upper portion 103 are parallel and horizontal, the lower portion 101 and the upper portion 103 are respectively connected to different floors, and the middle portion 102 is obliquely located between the lower portion 101 and the upper portion 103. A bent turning section is provided at the junction between the middle portion 102 and the lower portion 101, and another bent turning section is provided at the junction between the middle portion 102 and the upper portion 103. The middle portion 102 of the original truss 10 has multiple transverse bar members 11 which are distributed in parallel.

[0028] Referring to FIG. 4, an embedded type updating escalator according to the present application includes a truss assembly, as well as stairs, stair guide rails, stair chains, a traction machine, skirt plates, inner and outer cover plates, a handrail system, and an electrical control system which are mounted in combination with the truss assembly. The truss assembly includes multiple sections, and the multiple sections specifically include a lower machine room 21, a lower turning section 22, multiple middle sections 23, an upper turning section 24 and an upper machine room 25. Widths of the lower machine room 21, the lower turning section 22, the multiple middle sections 23, the upper turning section 24 and the upper machine room 25 are smaller than an inner transverse width of the original truss 10, so that they can be embedded into the original truss 10. The lower machine room 21, the lower turning section 22, the multiple middle sections 23, the upper turning section 24 and the upper machine room 25 are embedded into corresponding positions of the original truss 10 respectively to avoid the transverse bar members 11 at the corresponding positions, and then other components of the embedded type updating escalator are mounted. The embedded type updating escalator can completely maintain the strength of the original truss 10.

[0029] Specifically, as shown in FIG. 5, the lower machine room 21 is embedded into the lower portion 101, the lower turning section 22 is embedded into the junction between the lower portion 101 and the middle portion 102, the multiple middle sections 23 are embedded into the middle portion 102, the upper turning section 24 is embedded into the junction between the middle portion 102 and the upper portion 103, and the upper machine room 25 is embedded into the upper portion 103.

[0030] As shown in FIG. 2A, the original truss 10 includes two upper chord members 121 and two lower chord members 122, where the upper chord members 121 and the lower chord members 122 each have an angle steel structure, the two upper chord members 121 are welded to two sides of an upper portion of the original truss 10 respectively, the two lower chord members 122 are welded to two sides of a lower portion of the original truss 10 respectively, and transverse edges of the upper chord members 121 and the lower chord members 122 extend toward an interior of the original truss 10.

[0031] As shown in FIG. 2B, the original truss 10 includes two chord members 121A and two lower chord members 122A, where the upper chord members 121A and the lower chord members 122A each have an rectangular tube structure, the two upper chord members 121A are welded to two sides of the upper portion of the original truss 10 respectively, and the two lower chord members 122A are welded to two sides of the lower portion of the original truss 10 respectively.

[0032] In order to embed the sections of the truss assembly into the original truss 10, the chord members of the truss assembly are arranged as shown in FIG. 6. As shown in FIG. 6, the arrangement of the chord members on each middle section 23 is taken as an example for description, the arrangement of the chord members of the lower machine room 21, the lower turning section 22, the upper turning section 24, and the upper machine room 25 is the same as that of each middle section 23. Each middle section 23 includes two upper chord members 231 and two lower chord members 232, where the upper chord members 231 and the lower chord members 232 each have an angle steel structure, the two upper chord members 231 are welded to two sides of an upper portion of the corresponding middle section 23 respectively, and the two lower chord members 232 are welded to two sides of a lower portion of the corresponding middle section 23 respectively. A transverse edge of each upper chord member 231 extends away from the corresponding middle section 23, and a transverse edge of each lower chord member 232 extends toward an interior of the corresponding middle section 23. The arrangement of the chord members of the middle sections 23 is beneficial to reducing the transverse width L of the middle sections 23, so that the middle sections 23 can be easily embedded into the original truss 10. Correspondingly, since the arrangement of the chord members of the lower machine room 21, the lower turning section 22, the upper turning section 24, and the upper machine room 25 is the same as that of each middle section 23, the lower machine room 21, the lower turning section 22, the upper turning section 24, and the upper machine room 25 can be easily embedded into the original truss 10. It is worth noting that the upper chord members 231 and the lower chord members 232 may be made of various materials.

[0033] As shown in FIG. 7, the structure of bent edges of a side plate can be used by the chord assembly to realize the function of the chord members. Specifically, the middle sections 23A are taken as an example, where each middle section 23A includes two side plates 233 which are located on two sides of the corresponding middle section 23A respectively. Each side plate 233 has an upper transverse edge 2331 and a lower transverse edge 2332 which are formed by bending, the upper transverse edge 2331 extends away from the corresponding middle section 23A, and the lower transverse edge 2332 extends toward an interior of the corresponding middle section 23A. By using the structure of bent edges of the side plate, the transverse widths of the sections of the chord assemblies can be further reduced, the number of components of the sections can be reduced, and the structure can be simplified.

[0034] An escalator updating method of use of the embedded type updating escalator is provided according to the present application, where the method is used to update the escalator while the original truss of the original escalator is reserved, and the method includes:

[0035] (A) removing other components of the original escalator except the original truss to reserve a complete structure of the original truss including the transverse bar members;

[0036] (B) embedding the multiple sections of the truss assembly into the original truss to avoid the transverse bar members during embedding, and connecting and fixing the truss assembly with the original truss; and

[0037] (C) mounting the stairs, the stair guide rails, the stair chains, the traction machine, the skirt plates, the inner and outer cover plates, the handrail system, and the electrical control system in combination with the truss assembly.

Many modifications to these embodiments are apparent for those skilled in the art. The general principles defined herein may be applied to other embodiments without departing from the spirit or scope of the present application.
