Description

Technical Field

[0001] The present invention relates to the technical field of sidewalks, and more particularly to a bottomless pit moving sidewalk. Background Art

[0002] Moving walkways are walkways with circulating pedals, and are fixed electric drive equipment used mainly to transport passengers. Unlike escalators, moving walkways do not have stair-like paths in the passenger boarding area when in operation, that is, there is no tread difference between adjacent pedals in the passenger area.

[0003] The pedals of the conventional moving walkway are generally driven by a dedicated pedal chain, and the rollers on both sides of the pedals move on fixed guide rails. At the ends of the moving walkway, the pedals are flipped by rotating wheels with a larger diameter, so that the pedals are switched from the running direction to the opposite direction for cyclic movement. In order to complete this flipping process, the pits at both ends are deep, which makes the installation of the moving walkway more difficult. Summary of the invention

[0004] The present invention overcomes the problem in the prior art that the turning of the moving walkway pedals is achieved by flipping, which requires a large depth of the pit and thus makes the construction more difficult. A pitless moving walkway is provided. During the turning process of the walkway pedals, the walkway pedals do not flip but move downward by translation. Therefore, the turning radius is small, so that the overall structure height is small. When installing the moving walkway, it can be directly installed on the ground without a pit, thereby reducing the difficulty of installation.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: a pitless moving walkway, including a truss, including: A left drive chain and a right drive chain are arranged along the length direction of the truss, and the left drive chain and the right drive chain are arranged on both sides of the width direction of the truss respectively; The sidewalk pedal is provided with a left connection part and a right connection part at both ends of the sidewalk pedal along the width direction of the truss, and the left connection part is arranged in parallel with the right connection part; the left connection part is rotationally connected with the left driving chain, and the right connection part is rotationally connected with the right driving chain.

[0006] The present invention sets a left connection part and a right connection part at both ends of the sidewalk pedal, and the left connection part and the right connection part are rotatably connected to the left drive chain and the right drive chain respectively, and a horizontal plane is formed by the left connection part and the right connection part, so that when the sidewalk pedal runs to the end of the left drive chain and the right drive chain, the sidewalk pedal does not flip, but moves up and down; when a pedestrian stands on the sidewalk pedal, the gravity of the person is transmitted to the left drive chain and the right drive chain through the left connection part and the right connection part, and the sidewalk pedal moves forward stably. Therefore, compared with the existing technology, when the sidewalk pedal in the present application moves to the end of the left drive chain and the right drive chain, the turning radius of the sidewalk pedal will not be increased, so that the overall structural height is small, and when installing the moving sidewalk, it can be directly installed on the ground without a pit, which reduces the installation difficulty, and at the same time saves the step of building a pit, saving construction costs.

[0008] When the sidewalk pedal runs to the ends of the left drive chain and the right drive chain, the diameters of L1 and L2 are equal, so that the sidewalk pedal can rotate around the left drive sprocket and the right drive sprocket at the same time, thereby ensuring that the sidewalk pedal can move up and down while remaining horizontal, thereby not increasing the turning radius, and making the entire turning radius equal to the diameter of the left drive sprocket and the right drive sprocket.

[0073] In one embodiment, a left guide rail 11 and a right guide rail 12 are respectively provided on both sides of the width direction of the truss 1; a left pedal roller 311 is provided on the left connecting portion 31, and a right pedal roller 321 is provided on the right connecting portion 32; the left pedal roller 311 rolls along the left guide rail 11; and the right pedal roller 321 rolls along the right guide rail 12.

[0074] The left guide rail 11 and the right guide rail 12 are respectively matched with the left pedal roller 311 and the right pedal roller 321. When a person or a heavy object stands on the sidewalk pedal 3, the gravity acting on the sidewalk pedal 3 is transmitted to the left guide rail 11 and the right guide rail 12 through the left pedal roller 311 and the right pedal roller 321, thereby improving the bearing capacity of the sidewalk pedal 3.

[0075] In order to further improve the bearing capacity of the sidewalk pedal 3 , a first pedal shaft 312 and a second pedal shaft 322 are arranged in parallel at the bottom of the sidewalk pedal 3 .

[0076] The left connecting part 31 is a short shaft, and the left connecting part 31 is arranged at one end of the first pedal shaft 312 by means of a latch limit, and the other end of the first pedal shaft 312 is provided with a first auxiliary roller 313, and the first auxiliary roller 313 abuts against the right guide rail 12. The first auxiliary roller 313 is arranged to cooperate with the left pedal roller 311, and is supported at both ends of the first pedal shaft 312, so as to provide a stable support for the sidewalk pedal 3.

[0077] The right connecting part 32 is a short shaft, and the right connecting part 32 is arranged at one end of the second pedal shaft 322 by means of a latch limit, and the other end of the second pedal shaft 322 is provided with a second auxiliary roller 323, and the second auxiliary roller 323 abuts against the left guide rail 11. The second auxiliary roller 323 is arranged to cooperate with the right pedal roller 321, and is supported at both ends of the second pedal shaft 322, so as to provide a stable support for the sidewalk pedal 3.

[0078] In one embodiment, a plurality of staggered reinforcing ribs 33 are disposed on the back of the sidewalk pedal 3. The reinforcing ribs 33 can increase the load-bearing capacity of the sidewalk pedal 3.

[0079] In one embodiment, the chain tensioning device 5 is arranged at the end of the truss 1 away from the driving main machine 41, and the chain tensioning device 5 includes: a tensioning frame 51 sliding along the length direction of the truss 1; a left tensioning shaft 52 and a right tensioning shaft 53 arranged on the tensioning frame 51, the left driving sprocket 23 at the end away from the driving main machine 41 is arranged on the left tensioning shaft 52, and the right driving sprocket 24 at the end away from the driving main machine 41 is arranged on the right tensioning shaft 53; a pushing device for pushing the tensioning frame 51 to move toward the end of the truss 1.

[0080] The pushing device can push the tensioning frame 51 toward one end in a direction away from the driving main unit 41, and the tensioning frame 51 drives the left tensioning shaft 52 and the right tensioning shaft 53 to move in a direction away from the driving main unit 41. The left tensioning shaft 52 drives the left driving sprocket 23 to move, and the right tensioning shaft 53 drives the right driving sprocket 24 to move, thereby tensioning the left driving chain 21 and the right driving chain 22.

[0081] In one embodiment, the pushing device includes an electric pushing device, which includes but is not limited to structures such as a cylinder and an oil cylinder. The pushing device in this embodiment includes a pushing rod 54 and an abutting spring 55 connected to the tensioning frame 51. A fixing plate 13 is provided on the truss 1. An abutting plate 56 is provided at the end of the pushing rod 54 away from the fixing plate 13. The abutting spring 55 is sleeved on the pushing rod 54, and the two ends of the abutting spring 55 abut against the fixing plate 13 and the abutting plate 56 respectively.

[0082] The abutment spring 55 can push the abutment plate 56 to move away from the fixed plate 13, so that the tensioning frame 51 keeps moving away from the driving mainframe 41. In this embodiment, two groups of pushing devices are provided along the width direction of the truss 1. The two groups of pushing devices simultaneously and stably push the truss 1 to move away from the driving mainframe 41, and the forces on both ends of the tensioning frame 51 are more evenly applied, and the tensioning effect is better.

[0083] In one embodiment, in order to adjust the tensioning force on the tensioning frame 51, a push nut 57 is provided on the side of the abutting plate 56 away from the fixing plate 13, and the push nut 57 is threadedly connected with the pushing rod 54. The push nut 57 is rotated to adjust the position of the push nut 57 on the pushing rod 54, so as to adjust the position of the abutting plate 56 on the pushing rod 54, thereby adjusting the compression amount of the abutting spring 55, adjusting the tension on the tensioning frame 51, and thus adjusting the tension on the left driving chain 21 and the right driving chain 22.

[0084] This embodiment is different from Embodiment 1 in that 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 to 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 a chain. The handrail synchronous wheel 62 is coaxially connected to the handrail friction wheel 63. The handrail friction wheel 63 drives the handrail belt 64 to move.

[0085] There are two sets of handrail driving devices 6, and the two sets of handrail driving devices 6 are respectively located on both sides of the truss 1. The handrail driving wheels 61 of the two sets of handrail driving devices 6 are respectively fixed on the left driving end shaft 43 and the right driving end shaft 44, and the rotation of the left driving end shaft 43 and the right driving end shaft 44 drives the two sets of handrail driving devices 6 to operate.

[0086] In one embodiment, a plurality of mounting plates 65 are arranged on the side wall of the truss 1, and 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, and the two handrail synchronous wheels 62 are the first handrail synchronous wheel 62 and the second handrail synchronous wheel 62. A plurality of mounting plates 65 are arranged in an array along the length direction of the truss 1, and adjacent handrail mounting shafts 651 are connected in staggered transmission through the first handrail synchronous wheel 62 and the second handrail synchronous wheel 62 in sequence. The handrail belt 64 cooperates with the handrail friction wheel 63 on each handrail mounting shaft 651 for transmission.

[0087] Two clamping wheels 66 corresponding to the handrail friction wheel 63 are also arranged on the mounting plate 65, and the two clamping wheels 66 are connected to the two ends of the arc-shaped steel sheet 67. The handrail belt 64 passes between the clamping wheels 66 and the handrail friction wheel 63, and the clamping wheels 66 compress the handrail belt 64 between the handrail friction wheel 63 and the clamping wheels 66 through the elastic force of the arc-shaped steel sheet 67.

[0088] In this embodiment, the number of mounting plates 65 can be arranged according to actual needs, and can adapt to handrails 64 of different lengths, increase the driving force of the handrails 64, and solve the problem of insufficient driving of the handrails 64 on long-distance sidewalks.

[0089] In the present application, the left connecting part 31 and the right connecting part 32 are respectively provided at the two ends of the sidewalk pedal 3, and the left connecting part 31 and the right connecting part 32 are respectively connected to the left driving chain 21 and the right driving chain 22 in rotation, and a horizontal plane is formed by the left connecting part and the right connecting part, so that when the sidewalk pedal 3 runs to the ends of the left driving chain 21 and the right driving chain 22, the sidewalk pedal 3 does not flip, but moves up and down; when a pedestrian stands on the sidewalk pedal, the gravity of the person 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 moves forward stably. Therefore, compared with the existing technology, when the sidewalk pedal 3 in the present application moves to the ends of the left driving chain 21 and the right driving chain 22, the turning radius of the sidewalk pedal will not be increased, so that the overall structural height is small, and when installing the moving sidewalk, it can be directly installed on the ground without a pit, thereby reducing the difficulty of installation. At the same time, the step of building a pit is omitted, saving construction costs.

[0090] In the present application, the power of a driving main unit 41 is used to simultaneously drive the left driving chain 21 and the right driving chain 22 to rotate, and at the same time drive the handrail 64 to move, so that the overall structure is more compact and the difficulty of installation is reduced and lowered; in addition, the number of mounting plates 65 can be arranged according to actual needs, and can adapt to handrails 64 of different lengths, increase the driving force of the handrail 64, and solve the problem of insufficient driving of the handrail 64 on long-distance sidewalks.
