Description

Technical Field

[0001] The utility model relates to the technical field of escalator structures, in particular to an extended cover plate locking structure of an escalator or a moving walkway. Background Art

[0002] In case of earthquake or if the building has expansion joints, the end supports of the escalator or moving walkway trusses need to be extended by the overlapped part to accommodate the theoretical maximum "inter-story movement" or expansion joint size of the building.

[0003] In the prior art, the floor plates of escalators or moving walkways need to be extended synchronously to deal with the above situation. Usually, two cross-blocking plates are used to cover the extended gap, but the structural strength is poor and there is a risk of tripping passengers due to its high and low structure.

[0004] Reference application number 201210381864.3, application name for earthquake protection device on escalator or moving walkway, and application number 201510922618.8, application name for extension setting component and passenger conveyor, both have some features of extension cover plate, but lack the locking of the extension cover plate. Therefore, the prior art meets the extension requirements of the support at the end of the expansion joint of an earthquake or a building, but when the overlap is long, the first cover plate is usually above the end support and cannot be extended into the machine room, and the cover plate maintenance switch cannot be installed under the first cover plate, that is, when the first cover plate is opened, the switch of the escalator cannot be stopped. Therefore, it is necessary to design a locking structure for the extension cover plate so that it can be synchronized with the first maintenance cover plate to ensure that the switch is stopped during assembly. Utility Model Content

[0005] The utility model aims to overcome the above-mentioned shortcomings and provide a technical solution that can solve the above-mentioned problems.

[0006] The extended cover locking structure of an escalator or a moving walkway comprises a cover group of normal length, an extended cover and a composite frame; the composite frame comprises side frames on both sides and an end transverse frame at one end of the two side frames, and an intermediate transverse frame is assembled in the middle of the two side frames, and the composite frame is divided into a first area for assembling the inspection cover group and a second area for assembling the extended cover by the intermediate transverse frame; the extended cover comprises a bracket portion at the lower end, a notch is arranged between the bracket portion and the extended cover, and the extended cover is clamped between the intermediate transverse frame and the end transverse frame by the notch.

[0007] Furthermore, the end transverse frame and the middle transverse frame both include a transverse plate and folding plates at both ends of the transverse plate and perpendicular to the transverse plate. The folding plates are parallel to the upper ends of the side frames and have assembly holes matching with the side frames.

[0008] Furthermore, an extension portion is provided on the side of the bracket portion, and the notch is located at the gap between the extension portion and the extension cover plate.

[0009] Furthermore, the bracket portion and the extension cover plate are assembled by riveting or welding.

[0010] Furthermore, the composite frame is made of aluminum alloy, carbon steel, or stainless steel.

[0011] The beneficial effects of the utility model are:

[0012] The extended cover plate is made as a separate piece, which does not affect the original floor plate structure; and through the gap between the bracket part and the extended cover plate, it cooperates with the middle horizontal frame and the end horizontal frame to lock the extended cover plate and make it immovable; during assembly, the cover plate needs to be assembled first, and during disassembly, the inspection cover plate needs to be opened first, so as to ensure that the switch is in the stopped state during assembly and disassembly.

[0013] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 3, including a cover plate group of normal length, an extended cover plate 1 and a composite frame 2; the composite frame 2 includes side frames 3 on both sides and an end transverse frame 4 at one end of the two side frames 3, and an intermediate transverse frame 5 is assembled in the middle of the two side frames 3, and the composite frame 2 is divided into a first area for assembling the inspection cover plate group and a second area for assembling the extended cover plate 1 through the intermediate transverse frame 5; the extended cover plate 1 includes a bracket portion 6 at the lower end, and a notch 7 is provided between the bracket portion 6 and the extended cover plate 1, and the extended cover plate 1 is clamped between the intermediate transverse frame 5 and the end transverse frame 4 through the notch 7.

[0020] The first cover plate of the floor plate is generally used as the inspection cover plate, with a lifting hole. The stop switch is generally installed under the first cover plate. When the inspection cover plate is opened, the stop switch is activated. The technical structure is designed so that after the extension cover plate 1 is locked, the inspection cover plate is still the first cover plate of the "normal length cover plate group". When the inspection cover plate is opened, the stop switch is activated.

[0021] The corresponding structural design mainly protects the extended cover plate 1 and the composite frame 2;

[0022] The composite frame 2 includes side frames 3 on both sides and an end transverse frame 4 at one end of the two side frames 3. At the same time, an intermediate transverse frame 5 is assembled in the middle of the two side frames 3. The composite frame 2 is divided into a first area for assembling the inspection cover group and a second area for assembling the extension cover 1 through the intermediate transverse frame 5; and the end transverse frame 4 and the intermediate transverse frame 5 both include a transverse plate 8, and folding plates 9 at both ends of the transverse plate 8 and perpendicular to the transverse plate 8. The folding plates 9 are parallel to the upper ends of the side frames 3 and are matched with assembly holes 10 between the side frames 3. The folding plates 9 are parallel to the side frames 3 to make the contact surface larger, and multiple assembly holes 10 are added to make the stability stronger during the assembly process.

[0023] The extension cover plate 1 includes a bracket portion 6 at the lower end, an extension portion 11 at the side of the bracket portion 6, and a notch 7 between the extension portion 11 and the extension cover plate 1, so that the extension cover plate 1 can be stuck between the middle transverse frame 5 and the end transverse frame 4.

[0024] The working principle is as follows: because the bracket of the extended cover plate 1 has a notch 7, and the notches 7 at both ends of the bracket are respectively located below the middle horizontal frame 55 and the horizontal frame 6, the extended cover plate 1 cannot be directly removed after installation, and the notch 7 on the bracket part 6 just hooks the frame. The steps for removing the extended cover plate 1 are: first remove the inspection cover plate in the normal cover plate assembly, then stop the switch action, stop the escalator, then remove the middle horizontal frame 55, and finally remove the extended cover plate 1. This ensures that the switch is in a stopped state during assembly and disassembly.

[0025] At the same time: the bracket part 6 and the extended cover plate 1 are assembled by riveting or welding; the composite frame 2 is made of aluminum alloy, carbon steel, or stainless steel.

[0026] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the utility model, which does not depart from the content of the technical solution of the utility model, belongs to the scope of the technical solution of the utility model.
