Description

Technical Field

[0001] This utility model relates to the field of passenger transport device technology, and in particular to an assembly and assembly device for on-site renovation and upgrading of escalators. Background Technology

[0002] Escalators, widely used in public transportation facilities, experience wear and tear on their components over time, necessitating replacement and renovation. In renovations that retain the truss structure, to ensure the replacement parts can be easily transported to the construction site, it's typically necessary to disassemble the components into smaller parts. While disassembling the escalator assembly into side panels significantly reduces its three-dimensional dimensions, assembling these parts on-site requires supporting the components and demands high assembly precision.

[0003] Chinese patent document CN106392409A discloses a technical solution for a welding positioning device for the upper and lower escalator assemblies, which consists of a base plate, support frame, clamping components, and cylinder adjusting components. The device involved in this technical solution is large in overall size and heavy in weight, making it unsuitable for the small size and light weight requirements of escalator renovation and upgrading projects.

[0004] Chinese patent document CN201722045U discloses a technical solution for a three-dimensional molding device for the upper drive assembly of an escalator's sidewalk. This device integrates multiple legs connected to a large base, and features multiple positioning holes and locking devices on the uprights to facilitate the assembly and positioning of different assemblies. However, the device in this technical solution is large and heavy, making it unsuitable for escalator renovation and upgrade projects.

[0005] None of the above solutions solved the problem of how to assemble the components of the escalator assembly into a whole with high precision and speed at the escalator renovation site. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides an assembly assembly device for escalator renovation and upgrading, including a device body, step positioning pins and clamping nuts; the step positioning pins and clamping nuts are in multiple sets and are fixed on the device body; the assembly is installed on the step positioning pins through multiple sets of reference holes and is fastened by the clamping nuts; the device body is composed of two side plate assemblies arranged at intervals and fixed into a whole by multiple connecting plates and bolt fasteners.

[0007] Preferably, the main body of the device further includes an elastic pin, which is used for positioning when the connecting plate is fixed to the side plate assembly.

[0008] Preferably, the spacing between the two side panel assemblies is determined by the width of the assembly.

[0009] Preferably, the side panel assembly is formed by welding a positioning plate and a support column into a whole.

[0010] Preferably, the positioning plate is provided with multiple sets of threaded holes, the spacing of which is consistent with the spacing of the reference holes of the assembly used for assembly, and the size of the threaded holes matches the thread of the stepped positioning pin.

[0011] Preferably, the support column includes independently adjustable feet.

[0012] Preferably, the stepped positioning pin has a first threaded surface, a second threaded surface, and a stepped surface. The first threaded surface is used to fix with the threaded hole of the positioning plate, the second threaded surface is used to fix with the clamping nut, and the stepped surface is used to position the reference hole of the support assembly.

[0013] Compared with existing technologies, the assembly and assembly device of this utility model disassembles the main body of the device into two sets of side plates and connecting plates, etc., which are small-sized parts that can be quickly assembled into a whole on the renovation site. This utility model has a high degree of adjustment freedom and a wide range of applications. The components of this utility model are characterized by small three-dimensional dimensions and light weight, which provides greater flexibility and solves the difficulties of narrow passages and inability to lift heavy objects during escalator renovation. By using the device of this utility model, the accuracy and efficiency of escalator assembly are greatly improved, thereby shortening the renovation cycle. Attached Figure Description
