Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sidewalks, more particularly, it relates to a pitless moving sidewalk. BACKGROUND

[0002] The moving sidewalk refers to a walkway with a circulating running pedal, which is mainly used for fixed power-driven equipment for transporting passengers. Unlike escalators, the moving sidewalk does not have a stepped ladder path in the passenger boarding area when running, that is, there is no tread difference between adjacent pedals in the passenger area.

[0003] The pedal of the moving sidewalk in the prior art is generally driven by a special pedal chain, and the rollers on both sides of the pedal move on the fixed guide rail. At the end of the moving sidewalk, the pedal is flipped by a rotating wheel with a large diameter, so that the pedal is switched from the running direction to the opposite direction for circulating movement. In order to complete this flipping process, the depth of the pit at both ends is large, which increases the installation difficulty of the moving sidewalk. SUMMARY

[0004] The present application overcomes the problem in the prior art that the turning of the moving sidewalk pedal is realized by flipping, which requires a large depth of the pit, thereby making the construction difficult. The present application provides a pitless moving sidewalk. In the process of turning the sidewalk pedal, the sidewalk pedal does not flip, but moves downward by translation, so the turning radius is small, the overall structure height is small, and the moving sidewalk can be installed directly on the ground without a pit, thereby reducing the installation difficulty.

[0005] In order to solve the above technical problems, the present application adopts the following technical scheme: a pitless moving sidewalk, comprising a truss, comprising:

[0006] Left and right drive chains are arranged along the length direction of the truss, and the left and right drive chains are arranged on both sides of the width direction of the truss, respectively;

[0007] The moving sidewalk pedal is provided with a left connecting portion and a right connecting portion at both ends along the width direction of the truss, respectively, and the left connecting portion and the right connecting portion are arranged in parallel; the left connecting portion is rotatably connected with the left drive chain, and the right connecting portion is rotatably connected with the right drive chain.

[0008] The left connecting part and the right connecting part are respectively arranged at two ends of the sidewalk pedal, and the left connecting part and the right connecting part are respectively rotationally connected with the left driving chain and the right driving chain; a horizontal plane is formed through the left connecting part and the right connecting part, so that when the sidewalk pedal moves to the end of the left driving chain and the right driving chain, the sidewalk pedal does not perform a turning motion, but performs an up-and-down translation motion; when a pedestrian stands on the sidewalk pedal, the gravity of the pedestrian is transmitted to the left driving chain and the right driving chain through the left connecting part and the right connecting part, and the sidewalk pedal stably moves forward. Therefore, compared with the prior art, the sidewalk pedal in the present application does not increase the turning radius of the sidewalk pedal when moving to the end of the left driving chain and the right driving chain, so that the overall structure height is small, and when the automatic sidewalk is installed, the automatic sidewalk can be directly installed on the ground without a pit, the installation difficulty is reduced, and the construction cost is saved.

Figure 2 and Figure 3As shown, the handrail driving device 6 includes a handrail driving wheel 61, a handrail synchronous wheel 62 and a handrail belt 64, the handrail driving wheel 61 is coaxially connected with the left driving sprocket 23 or the right driving sprocket 24, the handrail driving wheel 61 drives the handrail synchronous wheel 62 to rotate through the chain belt, and the handrail synchronous wheel 62 is coaxially connected with a handrail friction wheel 63, and the handrail friction wheel 63 drives the handrail belt 64 to move.

[0107] The handrail driving device 6 is provided with two sets, and the two sets of handrail driving device 6 are located on the two sides of the truss 1. The handrail driving wheels 61 of the two sets of handrail driving device 6 are fixedly arranged on the left driving end shaft 43 and the right driving end shaft 44 respectively, and the rotation of the left driving end shaft 43 and the right driving end shaft 44 drives the two sets of handrail driving device 6 to operate.

[0108] In one embodiment, a plurality of mounting plates 65 are arranged on the side wall of the truss 1, two handrail mounting shafts 651 are arranged on each mounting plate 65, the handrail synchronous wheel 62 and the handrail friction wheel 63 are coaxially arranged on the handrail mounting shaft 651, and two handrail synchronous wheels 62 are arranged on each handrail mounting shaft 651, the two handrail synchronous wheels 62 are a first handrail synchronous wheel 62 and a second handrail synchronous wheel 62. A plurality of mounting plates 65 are arranged along the length direction of the truss 1, and adjacent handrail mounting shafts 651 are connected in turn through the first handrail synchronous wheel 62 and the second handrail synchronous wheel 62.

[0109] Two pressing wheels 66 corresponding to the handrail friction wheel 63 are also arranged on the mounting plate 65, and the two pressing wheels 66 are connected to the two ends of the arc-shaped steel sheet 67. The handrail belt 64 passes between the pressing wheel 66 and the handrail friction wheel 63, and the pressing wheel 66 presses the handrail belt 64 between the handrail friction wheel 63 and the pressing wheel 66 through the elastic force of the arc-shaped steel sheet 67.

[0110] The number of mounting plates 65 in the embodiment can be arranged according to actual needs, can adapt to handrail belts 64 of different lengths, increase the driving force of the handrail belt 64, and solve the problem of insufficient driving of the handrail belt 64 of the long distance sidewalk.

Therefore, compared with the prior art, the sidewalk deck 3 in the application will not increase the turning radius of the sidewalk deck when moving to the end of the left driving chain 21 and the right driving chain 22, so that the overall structure height is smaller, and when the automatic sidewalk is installed, it can be directly installed on the ground without the pit, thereby reducing the installation difficulty. At the same time, the step of building the pit is saved, and the construction cost is saved.
