Description

Automatic sidewalk pedal structure

Technical Field

The utility model relates to a moving walk technical field, in particular to can use moving walk footboard structure in the moving walk field.

Background

A travelator refers to a conveyor that continuously transports people in a horizontal or slightly inclined direction. The method is mainly used for stations, shopping malls, airports, exhibition halls, gymnasiums and other places where people flow intensively. The structure of the escalator is similar to that of an escalator, and the visible area mainly comprises two parts, namely a handrail and a movable pavement. The handrail is mainly a part which is held stably when a passenger stands; the travelator, which is the part of the area on which passengers stand and which transports them from one location to another, is the main part of the travelator and is usually called the tread area.

In the structural design of the existing moving sidewalk, a pedal area is generally a bearing area formed by connecting a plurality of pedals end to end, and the pedals are usually formed by integral injection molding. In the manufacturing process, the cost of the mold is different for pedals with different sizes and structures, but the cost for opening the mold is higher in general. During installation, the pedals are typically connected by a dedicated pedal chain, and each pedal is pivotally secured in a corresponding position so that the pedals can follow a designed path. However, when the maintenance and replacement are performed, the pedal is usually removed from the pedal pivot, and after the maintenance and replacement is completed, the pedal is positioned and locked again, so that the process is complex, the time cost is high, and the conventional pedal structure needs to be improved for solving the problems.

Disclosure of Invention

In order to solve the problem, the utility model discloses a comparatively simple structure's novel moving walk footboard structure.

The utility model discloses the technical problem that will solve can realize through following technical scheme:

a pedal structure of a moving sidewalk comprises pedals and side plates fixed on two sides of the pedals facing a driving chain, wherein a front pedal wheel and a rear pedal wheel are respectively arranged at the front end and the rear end of each side plate in a shaft mode; a detachable pedal gear shaft is fixed on each side plate, and one end, facing the driving chain, of each pedal gear shaft is movably connected with the driving chain.

In a preferred embodiment of the present invention, a shaft hole is formed at one end of the pedal gear shaft facing the driving chain, an outer shaft is fixed to a link of the driving chain corresponding to the pedal gear shaft, and a shaft end of the outer shaft is inserted into the shaft hole of the pedal gear shaft and is rotatably fitted to the shaft hole of the pedal gear shaft.

In a preferred embodiment of the present invention, a boss is fixed to each side plate, a shaft hole is provided in the boss, and the shaft end of the pedal gear shaft is inserted into the shaft hole of the boss and is fixedly connected to the shaft of the pedal gear shaft by passing through the boss.

In a preferred embodiment of the present invention, a reinforcing plate for reinforcing is symmetrically disposed on the lower side of the pedal.

Since the technical scheme as above is adopted, the utility model discloses in whole footboard structure, the motion of footboard drives through detachable footboard gear shaft, and the footboard is connected admittedly to the one end of footboard gear shaft promptly, other end swing joint driving chain. The pedal is driven by the driving chain to operate according to a preset design, and meanwhile, when the end part is reversed, the translation reversing process is realized through the teeth on the pedal gear shaft.

The utility model has the advantages that the detachable pedal gear shaft is adopted for connection, which is convenient for maintenance and replacement; moreover, since no dedicated pedal pivot is required to connect the pedals, the cost can be reduced.

Drawings

The invention is described in detail by way of example with reference to the following drawings, in which:

FIG. 1 shows an isometric view of a pedal from a perspective;

FIG. 2 shows a side view of the pedal;

FIG. 3 shows a top view of the connection of the pedals to the drive chain;

figure 4 shows a side view of an example of the utility model

Detailed Description

Referring to fig. 1 to 3, the present invention is suitable for a novel structure of a moving sidewalk pedal, including a pedal 1, a side plate 9 is fixed on each side of the pedal 1 facing a driving chain 7, and a

pedal front wheel

2a, 2b and a pedal

rear wheel

3a, 3b are respectively axially arranged at the front end and the rear end of each side plate 9; a boss 4 is fixed at the middle position of each side plate 9d, a shaft hole is arranged in the boss 4, and the shaft end 5a of the detachable pedal gear shaft 5 is inserted into the shaft hole of the boss 4 and is fixedly connected with the pedal gear shaft 5 through a pin shaft 8 penetrating through the boss 4 and the pedal gear shaft 5.

One end of the pedal gear shaft 5 facing the driving chain 7 is provided with a shaft hole 5b, an external shaft 6 is fixed on a chain link of the driving chain 7 corresponding to the pedal gear shaft 5, and the shaft end of the external shaft 6 is inserted into the shaft hole 5b of the pedal gear shaft 5 and is in running fit with the shaft hole 5b of the pedal gear shaft 5, so that the pedal 1 can move on the surface of the running guide rail under the driving of the driving chain 7.

Reinforcing plates 10 for reinforcement are provided symmetrically on the lower side in the width direction of the pedal 1. The pedal gear shaft 5 on the pedal 1 is fixed relative to the pedal 1 and is connected and fixed mainly through a pin 8, and the outward extending shaft 6 on the driving chain 7 can rotate in the shaft hole 5b at one end of the pedal gear shaft 5.

Fig. 4 shows a suitable application of the invention, in this case, in a straight section, the pedals 1 are moved together by the drive chain 7. At the turning end, the pedal gear on the pedal gear shaft 5 on the pedal 1 starts to mesh with the planet gear in the reversing device 11, the sun gear in the reversing device is fixed, and the planet gear is mounted on the driving chain wheel and always meshes with the sun gear. Under the drive of the drive sprocket, the pedal gear shaft 5 drives the pedal 1 to start reversing, and the pedal 1 moves from the main guide rail 12 to the return guide rail 13 to start reverse movement.

The above examples are only preferred embodiments of the present invention, and other applications of the present invention are possible, and other equivalent modifications or substitutions of the technical features described in the claims of the present application or other applications of the present invention can be considered to be within the scope of the claims.
