DETAILED DESCRIPTION

[0029] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices consistent with some aspects of the present application as detailed in the appended claims.

[0030] Example 1

[0031] A spiral escalator running stabilization device, such as Figure 1-Figure 11As shown, it includes a step rail 101, on which a plurality of step members 102 for pedestrians to step on are arranged, the step member 102 is fixedly connected to two step fixing frames 103, a first rotating rod 104 is rotatably connected between the two step fixing frames 103, a plurality of first rotating rods 104 are connected to the escalator driving device through a sprocket, both ends of the first rotating rod 104 are provided with rotating wheels for the step member 102 to transport pedestrians, the two step fixing frames 103 are both threadedly connected to a second rotating rod 105, and the opposite ends of the two second rotating rods 105 are both rotatably connected to a rectangular slide The moving part 106 and the rectangular sliding part 106 are located in the step guide rail 101. The two rectangular sliding parts 106 are both provided with rotating wheels and guide wheels for the step parts 102 to transport pedestrians. The escalator driving device drives a plurality of step parts 102 to run along the step guide rail 101 through a sprocket. Two adjacent step fixing frames 103 are fixedly connected to two anti-jump frames 107 on the back sides. The four anti-jump frames 107 run along the step guide rail 101 following the adjacent step parts 102, and limit the adjacent step parts 102 during operation to prevent the step parts 102 from jumping and falling out of position.

[0032] The escalator driving device drives several step members 102 to run along the step guide rail 101 through a sprocket. During the operation of the escalator, the step members 102 drive four adjacent anti-jump frames 107 to run along the step guide rail 101. The four anti-jump frames 107 cooperate with the step guide rail 101 to prevent the step members 102 from jumping and falling out of position, thereby ensuring the safety of people walking on the step members 102.

[0033] Example 2

[0034] On the basis of Example 1, Figure 3 and Figure 4 As shown, the step jump buffer mechanism includes an anti-jump sliding member 201, and a plurality of anti-jump sliding members 201 are provided. The plurality of anti-jump sliding members 201 are respectively slidably connected to the upper and lower ends of adjacent anti-jump frames 107. The end of the anti-jump sliding member 201 that contacts the step guide rail 101 is set as a rotating wheel to reduce the friction force of the step member 102 during operation. A first spring 202 for buffering is fixedly connected between the anti-jump sliding member 201 and the anti-jump frame 107. Through the first spring 202, a force in the opposite direction is applied to the step member 102 that jumps up or sinks, and the reset step member 102 is buffered to avoid excessive misalignment of the step member 102 that jumps up or sinks.

[0035] When the step member 102 jumps and is misplaced, the anti-jump frame 107 drives the two anti-jump sliding members 201 to move upward. During this process, the anti-jump sliding member 201 on the lower side does not move upward under the limiting action of the step guide rail 101, and the anti-jump frame 107 moves upward to squeeze the first spring 202. The first spring 202 is squeezed and produces a reverse force on the anti-jump frame 107 moving upward, slowing down the upward movement trend of the anti-jump frame 107. When the anti-jump frame 107 moves and resets, the anti-jump frame 107 moving and resetting is buffered under the action of the anti-jump sliding member 201 and the first spring 202 on the upper side.

[0036] When the step member 102 falls and is misplaced, the anti-jump frame 107 drives the two anti-jump sliding members 201 to move downward. During this process, the anti-jump sliding member 201 on the upper side does not move downward under the limiting action of the step guide rail 101, and the anti-jump frame 107 moves downward to squeeze the first spring 202. The first spring 202 is squeezed and produces a reverse force on the anti-jump frame 107 moving downward, slowing down the downward movement trend of the anti-jump frame 107. When the anti-jump frame 107 moves and resets, the anti-jump frame 107 moving and resetting is buffered under the action of the anti-jump sliding member 201 and the first spring 202 on the lower side.

[0037] Example 3

[0038] On the basis of Example 2, Figure 5-Figure 7 As shown, the anti-step reverse mechanism includes a third rotating rod 301, and a plurality of third rotating rods 301 are provided. The plurality of third rotating rods 301 are respectively threadedly connected to adjacent step fixing frames 103, and a fourth rotating rod 302 is splined between two adjacent third rotating rods 301. The fourth rotating rod 302 and the adjacent first rotating rod 104 are driven by a pulley and a belt, and the pulley on the fourth rotating rod 302 is a one-way pulley. The two adjacent step fixing frames 103 are both provided with n-type fixing frames 303 on the opposite sides, and each n-type fixing frame 303 is provided with a plurality of third rotating rods 301. 03 are all slidably provided with circular plates 304, and the opposite sides of two adjacent circular plates 304 are provided with first deceleration members 305, and the friction coefficient of the opposite sides of the two adjacent first deceleration members 305 on the left and right is greater than the friction coefficient that decelerates the step member 102, and is used to decelerate the step member 102. The first deceleration member 305 is driven by the first rotating rod 104 to move to contact the step guide rail 101, so as to decelerate the reverse step member 102, and the n-type fixed frame 303 is provided with an anti-step reverse assembly for decelerating the reverse step member 102.

[0039] like Figure 5-Figure 7As shown, the anti-step reverse assembly includes a second speed reducer 306, and the second speed reducer 306 is provided with a plurality of them. The plurality of second speed reducers 306 are respectively rotatably connected to adjacent n-type fixing frames 303, and each n-type fixing frame 303 is rotatably connected to a third speed reducer 307, and each third speed reducer 307 is rotatably connected to an adjacent second speed reducer 306. Both ends of each second speed reducer 306 and third speed reducer 307 are set as irregular planes to prevent the step member 102 from reverse, and four stoppers 308 are fixedly connected to the back sides of two adjacent circular plates 304. The second speed reducer 306 and the third speed reducer 307 are both provided with inclined surfaces, and the limit member 308 is provided with an inclined surface. The inclined surfaces of the second speed reducer 306 and the third speed reducer 307 are respectively squeezed and matched with the inclined surfaces of the adjacent limit members 308 to prevent the step member 102 from reversing. The circular plate 304 drives the limit members 308 thereon to move and squeeze the second speed reducer 306 and the third speed reducer 307, and drives the second speed reducer 306 and the third speed reducer 307 to gradually move from a cross shape to a straight shape, and squeeze the step guide rail 101 to slow down the trend of the step member 102 to reverse.

[0040] When the step member 102 suddenly reverses during the ascending process, the first rotating rod 104 drives the fourth rotating rod 302 to rotate in the opposite direction through the pulley and the belt. The reverse rotation of the fourth rotating rod 302 drives the two adjacent third rotating rods 301 to move. The two third rotating rods 301 move in opposite directions respectively. The third rotating rod 301 drives the first deceleration member 305 to move through the circular plate 304 until the first deceleration member 305 moves to contact the step guide rail 101, thereby decelerating the reversed step member 102, reducing the reverse trend of the step member 102, and preventing the reverse step member 102 from causing harm to pedestrians on it.

[0041] In the above process, the circular plate 304 drives the limiting member 308 thereon to move and squeeze the second speed reducer 306 and the third speed reducer 307. After being squeezed, the second speed reducer 306 and the third speed reducer 307 cross-move in a direction perpendicular to the step guide rail 101. In this process, the second speed reducer 306 and the third speed reducer 307 gradually move from a cross shape to a straight shape, and squeeze the step guide rail 101, thereby slowing down the reverse step member 102 and reducing the reverse trend of the step member 102 to prevent the reverse step member 102 from causing harm to pedestrians on it, until the step member 102 no longer reverses.

[0042] When the step member 102 stops moving backward, the second speed reducer 306 and the third speed reducer 307 that cross and move toward each other in a straight line are fixed to the first speed reducer 305 that contacts the step guide rail 101 to prevent the step member 102 from moving backward.

A second spring 402 is fixedly connected between the step fixing frame 103 and the adjacent detection members 401. The opposite sides of the two adjacent detection members 401 are fixedly connected to the first toothed plates 403. The two adjacent first toothed plates 403 are staggered. Each step member 102 is rotatably connected to a There are two worm gears 404, each of which is keyed to a first gear 405. The two adjacent first gears 405 are respectively meshed with the first tooth plates 403 in opposite directions. A worm wheel 406 is fixed to the second rotating rod 105. The worm wheel 406 meshes with the adjacent worm gears 404. The positioning member 401 in the offset direction is squeezed and moved, and the rectangular sliding member 106 in the opposite direction and the components thereon are moved away from the offset direction to avoid the step member 102 from falling after the step member 102 is offset, thereby threatening the life safety of pedestrians. A step offset protection component for protecting pedestrians is provided on the step member 102.

The sixth rotating rod 412 is key-connected to a second bevel gear 413, and the second bevel gear 413 is meshed with the adjacent first bevel gear 410. The fourth rotating rod 302 is driven to rotate through the positioning member 401 to avoid the step member 102 being in a running state after being offset, thereby protecting the lives of pedestrians on the step member 102.

[0046] When a certain step member 102 deviates, the detection member 401 in the deviating direction is squeezed and moves, and squeezes the adjacent second spring 402. The second spring 402 generates a reverse force after being squeezed, and the detection member 401 drives the adjacent first tooth plate 403 to move. The first tooth plate 403 drives the worm 404 to rotate through its first gear 405 in the opposite direction. The worm 404 is driven by the worm wheel 406 to rotate the second rotating rod 105 in the opposite direction of the deviating direction. The second rotating rod 105 drives the rectangular sliding member 106 and the components thereon to move away from the deviating direction through the adjacent step fixing frame 103, so as to prevent the step member 102 from falling after the deviating, thereby threatening the life safety of pedestrians.

[0047] When the step member 102 deviates to the left, the positioning member 401 on the left is squeezed, and the above steps are repeated, and the first tooth plate 403 on the left drives the second tooth plate 408 to move to the right, and the second tooth plate 408 drives the fourth rotating rod 302 to rotate through the second gear 409, the fifth rotating rod 407, the first bevel gear 410, the second bevel gear 413 and the sixth rotating rod 412, and the above steps are repeated to avoid the step member 102 from being in operation after being deviated, thereby protecting the lives of pedestrians on the step member 102.

In this process, the left worm 404 drives the fifth rotating rod 407 to rotate through the pulley and belt, and the above steps are repeated to prevent the step member 102 from remaining in operation after deviating, thereby protecting the lives of pedestrians on the step member 102.
