Description

Technical Field

[0001] The present invention relates to the technical field of escalators, and more particularly to a continuous multi-wave escalator. Background Art

[0002] Currently, most escalators on the market are straight or curved. Although they can meet basic transportation needs, they still have some shortcomings. Especially for scenes with higher heights, straight escalators go straight up and down, which can easily cause great visual pressure for passengers. Some escalators adopt a wavy structure, with the middle section of the escalator set horizontally and moving horizontally in the middle section, which can improve the riding experience of passengers. The most common wavy escalators on the market are usually two-stage or three-stage structures.

[0003] In current escalators, the handrails are driven by a single escalator drive mechanism. As the escalator's length increases, the handrail length also increases, making it difficult to drive the handrail smoothly. Furthermore, as the escalator's length increases, the number of passengers on board also increases. Passengers' gripping pressure creates significant frictional resistance on the handrails, leading to significant differences in tension on the downward-facing sides of the handrails. This can cause the handrails to become partially overtightened or partially overslack, compromising their smooth operation and, to a certain extent, hindering the normal operation of the escalator.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Invention

[0022] The escalator handrail is driven by two sets of driving mechanisms, which can stably drive the handrail. Moreover, since the two sets of driving mechanisms are respectively located near the upper and lower ends of the handrail, they can drive the handrail near the upper and lower ends, avoiding the traction length being too long when driven by a single driving mechanism, and can stably drive the handrail.

Compared with the direct contact of the guide wheel, it can improve the smoothness of the handrail when passing. By providing a raised portion on the surface of the annular guide belt, when the raised portion of the annular guide belt is in one of the gaps, frictional contact will be generated between the handrail and the friction member. The friction member does not rotate with the friction of the handrail, and the friction member remains stationary. The two form a friction resistance, which can produce friction obstruction on the lower section of the handrail. By limiting the friction on the lower section, the friction force on the upper section of the handrail is balanced, maintaining the force stability of the upper and lower sections of the handrail, and keeping the overall tension of the handrail balanced.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1

[0039] This embodiment discloses a continuous multi-wave escalator, referring to Figure 1 As shown, it includes at least two inclined segments and several horizontal segments. Adjacent inclined segments are connected by horizontal segments. Multiple inclined segments and horizontal segments are connected to form an inclined wavy structure.

[0040] Specifically, the escalator in this embodiment has a four-wave structure, with four inclined sections, namely a first inclined section 11, a second inclined section 12, a third inclined section 13, and a fourth inclined section 14. A first horizontal section 15 is provided between the first inclined section 11 and the second inclined section 12, a second horizontal section 16 is provided between the second inclined section 12 and the third inclined section 13, and a third horizontal section 17 is provided between the third inclined section 13 and the fourth inclined section 14. The four inclined sections are arranged in sequence to form a four-wave structure.

[0041] By connecting horizontal sections between adjacent inclined sections, the length of the continuous inclination can be shortened, that is, a horizontal structure can be formed between the two inclined sections, thereby improving the passengers' riding experience, avoiding long-term inclined and ascending riding, and reducing the passengers' sense of stress and fatigue during the ride.

[0042] Reference Figure 1 、 Figure 2As shown, this embodiment includes handrails 2 arranged along the inclined and horizontal sections, forming handrail structures on both sides of the escalator, capable of automatically rising and falling with the escalator. The handrails 2 are annular in structure and can be driven by two sets of drive mechanisms to form two handrails on either side of the escalator.

[0043] In this embodiment, the escalator has a four-wave structure. The escalator's inclination is long, resulting in a corresponding increase in the length of the handrail 2. The two drive mechanisms work together to improve the smoothness and fluidity of the handrail 2. The two drive mechanisms are located near the upper and lower ends of the handrail 2, and the handrail 2 is driven by bypassing each of the two drive mechanisms.

[0044] Reference Figure 2-Figure 4 As shown, the two drive mechanisms are a first drive mechanism 3 and a second drive mechanism 4. The first drive mechanism 3 is located near the inclined lower end of the handrail 2, and the second drive mechanism 4 is located near the inclined upper end of the handrail 2. Both drive mechanisms are located in the lower half of the handrail 2 and can drive the handrail 2. Since the two drive mechanisms are located near the upper and lower ends, respectively, they can drive the handrail 2 near both ends, ensuring stable operation of the handrail 2.

[0045] Reference Figure 3 、 Figure 4 As shown, the drive mechanism includes a drive wheel 31. The drive wheel 31 is driven to rotate by a driver, and a portion of the handrail belt 2 can pass through the drive wheel 31. The friction between the drive wheel 31 and the handrail belt 2 drives the handrail belt 2. The drive wheel 31 is driven by a drive motor and a transmission belt, which in turn drives the handrail belt 2.

[0046] In order to form a stable wrap angle on the periphery of the driving wheel 31 and improve the contact stability between the driving wheel 31 and the handrail belt 2, a stable friction force effect can be provided, thereby driving the handrail belt 2 to operate stably.

[0047] A guide support frame 1 32 and a guide support frame 2 33 are respectively provided on both sides of the driving wheel 31. The guide support frame 1 32 is equipped with a plurality of guide wheels 1 321, and the guide support frame 2 33 is equipped with a plurality of guide wheels 2 331. The guide wheels 1 321 and 331 are both used for the handrail belt 2 to pass around. Through the guidance of the guide wheels 1 321 and 331, the handrail belt 2 can be guided and limited, thereby forming a more stable and smooth direction, so that the contact area between the handrail belt 2 and the driving wheel 31 is more stable, and effective driving is performed to reduce slippage. In accordance with the direction of the handrail belt 2 on both sides of the driving wheel 31, the guide wheels 1 321 and 331 are arranged in an arc shape, respectively guiding the handrail belt 2 passing through the two sides of the driving wheel 31 to roll. The arc-shaped arrangement structure can maintain the smoothness of the direction of the handrail belt 2.

[0048] Furthermore, the guide support frame 2 33 near the driving wheel 31 and the guide wheel 2 331 installed on the guide support frame 2 33 are further designed. By installing an annular guide belt 5 on the outer periphery of the guide wheel 2 331 to increase the contact area with the handrail belt 2, the transmission stability can be improved.

[0049] The second guide support frame 33 is located between the two sets of driving mechanisms. Figure 3 It is a structural diagram of the first driving mechanism 3. Figure 3 The middle guide support frame 2 33 is located on the right side of the figure; Figure 4 is a structural diagram of the second driving mechanism 4. Figure 4 The second middle guide support frame 33 is located on the left side of the figure, and both sets of second guide support frames 33 are located near the middle of the driving mechanism.

[0050] Each set of driving mechanisms is provided with an annular guide belt 5, which surrounds the outer side of each guide wheel 331 and forms a nearly arc-shaped direction on the side close to the handrail belt 2, forming an arc-shaped linkage section 501, while the side facing away from the handrail belt 2 is tensioned by the tensioning wheel 332 to keep the annular guide belt 5 in a flat and tensioned state. Figure 5 As shown, in this embodiment, the specific structure of the second guide support frame 33 in the first driving mechanism 3 is used for description.

[0051] The guide belt 5's arcuate linkage section 501 forms the point where it passes over each of the second guide wheels 331, while the point facing away from the second guide wheels 331 forms the tensioning section 502. During operation, the handrail 2 passes over the arcuate linkage section 501 of the guide belt 5, creating a smooth, arc-shaped, and stable contact. This improves the smoothness of the handrail 2's passage compared to direct contact with the second guide wheels 331.

[0052] A friction member 6 is also installed on the second guide support frame 33. The friction member 6 is close to one of the second guide wheels 331, and Figure 5 The second guide wheel 2 331 from right to left in the middle. A gap 600 is formed between the friction member 6 and the corresponding guide wheel 2 331.

[0053] A raised portion 51 is integrally connected to the outer side of the annular guide belt 5. The raised portion 51 protrudes from the outer surface of the annular guide belt 5, increasing the overall thickness of the annular guide belt 5 at the corresponding location of the raised portion 51. The raised portion 51 is made of the same material as the annular guide belt 5 and can adapt to the circular motion of the annular guide belt 5, ensuring smooth movement of the annular guide belt 5 during its rotation.

[0054] The sum of the thickness of the annular guide belt 5 and the handrail belt 2 is less than the width of the gap 600. The sum of the thickness of the annular guide belt 5, the handrail belt 2 and the protrusion 51 is greater than the width of the gap 600. Figure 6 shown.

[0055] During the operation of the annular guide belt 5 and the handrail belt 2, when the raised portion 51 of the annular guide belt 5 is not at the gap one 600, the annular guide belt 5 contacts the corresponding guide wheel two 331, and the handrail belt 2 contacts the annular guide belt 5. There is no direct contact between the handrail belt 2 and the friction member 6, and no friction obstruction is formed between the friction member 6 and the handrail belt 2.

[0056] When the raised portion 51 of the annular guide belt 5 is at the gap 600, the raised portion 51 also enters the gap 600, and the annular guide belt 5, the handrail belt 2 and the raised portion 51 are stacked on each other. Figure 6 、 Figure 7 As shown, the thickness after lamination must exceed the size of the gap 600, and friction contact will be generated between the handrail belt 2 and the friction member 6. The friction member 6 does not rotate with the friction of the handrail belt 2, and the friction member 6 remains stationary, and the two form a friction resistance.

[0057] Reference Figure 2 As shown, during operation, the handrail 2 is partially located on the upper side of the handrail, i.e., the upper section 201, and partially located on the lower side of the handrail, i.e., the lower section 202. In particular, because passengers tend to lie prone, the upper section 201 is subjected to pressure, resulting in significant frictional contact with the support portion of the frame, generating significant frictional resistance in the upper section 201. On the lower side of the handrail 2, i.e., the lower section 202, the guide contact via the guide wheels results in rolling contact. This results in a significant difference in resistance between the upper section 201 and the lower section 202 of the handrail 2, and a difference in tension between the two sections.

[0058] The combined effect of the raised portion 51, combined with the frictional resistance of the friction member 6, can produce intermittent frictional resistance on the handrail 2. Furthermore, the guide support frame 2 33 is located at the lower section 202 of the handrail 2, and the frictional force position of the handrail 2 is located between the two sets of drive mechanisms, thereby forming a frictional limiter at the lower section 202 of the handrail 2. The frictional limiter at the lower section 202 balances the frictional force at the upper section 201 of the handrail 2, maintaining the force stability of the upper and lower sections 201, 202 of the handrail 2, and keeping the overall tension of the handrail 2 balanced.

[0059] Reference Figure 6 As shown, the two sides of the raised portion 51 smoothly transition to the surface of the handrail 2 through the transition portion 52, and the thickness of the transition portion 52 gradually decreases in the direction away from the raised portion 51, thereby forming a smooth direction, avoiding excessive jerking feeling when the raised portion 51 contacts.

[0060] Example 2

[0061] This embodiment discloses a continuous multi-wave escalator. Figures 9-11 Provide detailed explanation.

[0062] In this embodiment, the friction member 6 adopts a wheel structure and a unidirectional rotating structure, that is, in the working state, the handrail belt 2 is in contact with the friction member 6 for transmission, and the friction member 6 can remain stationary, forming friction resistance on the handrail belt 2.

[0063] Reference Figure 9 As shown, the friction member 6 includes a friction wheel 60 and a support shaft 61. The support shaft 61 is fixed to the second guide support frame 33. The friction wheel 60 is rotatably connected to the outside of the support shaft 61 and realizes one-way transmission limitation through a ratchet mechanism.

[0064] The ratchet mechanism can perform one-way transmission control on the friction wheel 60. Figure 9 As shown, this structure, mounted on the guide support frame 2 33, is primarily suitable for use in upward elevators. This means that the upper section 201 of the handrail 2 is tilted upward, while the lower section 202 of the handrail 2 is tilted downward. The friction wheel 60 can rotate counterclockwise, but is limited in the clockwise direction by the ratchet structure.

[0065] specifically refer to Figure 9As shown, the support shaft 61 is fixedly mounted, and the friction wheel 60 is rotatably connected to the outer periphery of the support shaft 61. When the ratchet mechanism is not engaged, the friction wheel 60 can rotate smoothly, forming a structure similar to the base of a bicycle. A ring sleeve 62 is coaxially fixedly mounted on the side of the friction wheel 60, and a fixed disk 63 is coaxially fixedly mounted on the outer periphery of the support shaft 61. The fixed disk 63 and the ring sleeve 62 are annularly mounted, and the ring sleeve 62 is mounted externally, forming an annular space 64 between the two. The ratchet mechanism is mounted between the fixed disk 63 and the ring sleeve 62. The outer periphery of the ring sleeve 62 is formed as a pulley 92.

[0066] Specifically, a second ratchet portion 67 is integrally formed on the inner circumference of the ring sleeve 62, forming an annular arrangement of ratchet teeth. A linkage tooth 65 is rotatably connected to the outer circumference of the fixed disk 63. The linkage tooth 65 has an outwardly facing ratchet portion 1 66, forming the other portion of the ratchet teeth. The ratchet portion 1 66 and the second ratchet portion 67 cooperate to achieve ratchet transmission. A stopper 68 is provided on the clockwise side of the linkage tooth 65. The stopper 68 is fixed to the fixed disk 63, blocking the linkage tooth 65 and thus creating a one-way block when the friction wheel 60 rotates clockwise. When the friction wheel 60 rotates counterclockwise, the linkage tooth 65 is deflected and displaced, allowing the linkage tooth 65 to rotate smoothly.

[0067] When the lower section 202 of the handrail belt 2 moves downward, the handrail belt 2 is lifted up by the protrusion 51. When the handrail belt 2 contacts the friction wheel 60, the handrail belt 2 and the friction wheel 60 are in friction contact. The friction wheel 60 will remain stationary. The friction wheel 60 can form a friction barrier on the handrail belt 2 to counteract the friction barrier on the upper section 201 of the handrail belt 2.

[0068] Since the handrail belt 2 and the friction wheel 60 are in frictional contact, it is mainly sliding friction, which will cause slight friction on the surface of the friction wheel 60. If they are in contact at the same position for a long time, the friction wheel 60 will be locally worn to a greater extent.

[0069] A freely rotatable linkage wheel 7 is rotatably connected to the second guide support frame 33. This linkage wheel 7 is located above the first guide wheel 321, forming a gap 2 between the linkage wheel 7 and the corresponding first guide wheel 321. The combined thickness of the annular guide belt 5 and the handrail 2 is less than the width of the gap 2; the combined thickness of the annular guide belt 5, the handrail 2, and the raised portion 51 is greater than the width of the gap 2.

[0070] Reference Figure 10 As shown, among the guide wheels 2 331 , one is a friction guide wheel 2 3311 , and the other is a linkage guide wheel 2 3312 . The friction guide wheel 2 3311 and the friction member 6 are close to each other, and a gap 600 is formed between them. The linkage guide wheel 2 3312 and the linkage wheel 1 7 are close to each other, and a gap 2 is formed between them.

[0071] The second guide support frame 33 is rotatably connected to a second linkage wheel 8, which is located above the first linkage wheel 7. The second linkage wheel 8 and the friction member 6 are connected via a transmission belt 9. A first pulley 91 is coaxially fixedly mounted on the second linkage wheel 8, and a second pulley 92 is coaxially fixedly mounted on the friction wheel 60. The first and second pulleys 91 and 92 are driven by a transmission belt 9, which can be a synchronous transmission belt to ensure stable transmission between the two.

[0072] Reference Figure 11 As shown, the linkage wheel 1 7 can be adjusted up and down. Specifically, a sliding groove 72 running up and down can be opened at the guide support frame 2 33. A slider 71 is slidably installed in the sliding groove 72. The slider 71 can be slid up and down along the sliding groove 72, so that the linkage wheel 1 7 also has a certain up and down movable stroke.

[0073] When the linkage wheel 1 7 is located at the relatively lower side of the stroke, that is, when the raised portion 51 of the annular guide belt 5 is not at the second gap, the lower side of the linkage wheel 1 7 is in contact with the annular guide belt 5, and the upper side of the linkage wheel 1 7 is separated from the linkage wheel 2 8. The linkage wheel 2 8 is not subjected to the force of the linkage wheel 1 7 and does not rotate, and the friction wheel 60 does not rotate either.

[0074] When the raised portion 51 on the outer side of the annular guide belt 5 passes under the side of the linkage wheel 1 7, the thickness of the annular guide belt 5, the raised portion 51, and the handrail 2 overlap, increasing the thickness to exceed the original width of gap 2, thereby driving the linkage wheel 1 7 upward. After the linkage wheel 1 7 is adjusted upward, the linkage wheel 1 7 drives the linkage wheel 2 8 to rotate. At the same time, the linkage wheel 2 8 and the friction wheel 60 also generate mutual transmission, causing the friction wheel 60 to rotate counterclockwise. During this rotation, the ratchet mechanism of the friction wheel 60 is not limited, allowing the friction wheel 60 to rotate through a certain angle, so that the position of the friction wheel 60 in contact with the handrail 2 can be changed. This prevents the friction wheel 60 from being in friction contact with the same position for a long time, and prevents excessive wear of the friction wheel 60 in some areas.

[0075] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
