Description

Technical Field

[0001] This invention relates to the field of escalator technology, and more specifically, to a continuous multi-wave escalator. Background Technology

[0002] Currently, most escalators on the market are straight or curved. While these meet basic transportation needs, they still have limitations. Especially in high-ceilinged areas, straight escalators, with their vertical up-and-down movement, can create significant visual pressure for passengers. Some escalators adopt a wave-shaped structure, with a horizontal section in the middle, improving the passenger experience. Common wave-shaped escalators on the market are usually two- or three-section structures.

[0003] Currently, escalators rely on a single drive mechanism to operate the handrail. As the length of the escalator increases, so does the length of the handrail, making smooth operation difficult. Furthermore, the increased length of the escalator and the number of passengers create significant frictional resistance on the handrail, leading to a noticeable difference in tension on both sides. This results in uneven tension, with some areas being too tight and others too loose, affecting the smoothness of the escalator's operation and potentially impacting its overall function.

[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0010] The present invention is further configured such that both the first guide wheel and the second guide wheel are arranged in an arc shape, respectively guiding the handrail belts that pass around both sides of the drive wheel.

[0011] The invention is further configured such that an annular guide belt is wound around the outer side of the second guide wheel and is kept taut by a tensioning wheel; the position where the annular guide belt passes around each second guide wheel is an arc-shaped linkage section, and the handrail belt passes around the arc-shaped linkage section and is frictionally driven with the arc-shaped linkage section.

[0012] The present invention is further configured such that the second guide support frame is located between the two sets of drive mechanisms, the second guide support frame is provided with a friction element, the friction element is close to one of the second guide wheels and forms a gap.

[0013] The present invention is further configured such that a protrusion is integrally connected to the outer side of the annular guide belt, the sum of the thicknesses of the annular guide belt and the handrail belt is less than the width of the first gap, and the sum of the thicknesses of the annular guide belt, the handrail belt and the protrusion is greater than the width of the first gap.

[0014] The present invention is further configured such that the two sides of the protrusion and the surface of the armrest belt are smoothly transitioned through a transition portion.

[0015] The present invention is further configured such that the friction component includes a friction wheel and a support shaft, the support shaft is fixed to the second guide support frame, the friction wheel is rotatably connected to the outside of the support shaft, and unidirectional transmission and limiting are achieved through a ratchet mechanism;

[0016] The present invention is further configured such that the guide support frame 2 is rotatably connected to a linkage wheel 1, the linkage wheel 1 is located on the upper side of the guide wheel 1, a gap 2 is formed between the linkage wheel 1 and the corresponding guide wheel 1, the sum of the thicknesses of the annular guide belt and the handrail belt is less than the width of the gap 2; the sum of the thicknesses of the annular guide belt, the handrail belt and the protrusion is greater than the width of the gap 2.

[0020] In summary, the present invention has the following beneficial effects:

[0021] By connecting horizontal segments between adjacent inclined segments, the length of continuous incline can be shortened, thus forming a horizontal structure between two inclined segments. This avoids prolonged incline riding, reduces passenger stress and fatigue during the ride, and improves the passenger experience.

[0022] By using two sets of drive mechanisms to drive the handrail belt of the escalator, the handrail belt can be driven stably. Since the two sets of drive mechanisms are located near the upper and lower ends, they can drive the handrail belt near the upper and lower ends, avoiding excessive traction length when driven by a single drive mechanism, and thus enabling stable driving of the handrail belt.

[0023] By setting guide wheels on both sides of the drive mechanism, the handrail belt that passes around the drive wheel can be smoothly guided, following the direction of the handrail belt on both sides of the drive wheel, and keeping the path of the handrail belt smooth. Guide wheel one and guide wheel two are arranged in an arc shape, respectively guiding the handrail belt that passes around both sides of the drive wheel. The arc arrangement structure can maintain the smoothness of the handrail belt.

[0024] The handrail belt wraps around the curved linkage section of the guide belt, forming a smooth, curved fit and creating stable contact. This improved smoothness compared to direct contact with the guide wheels. By locally creating protrusions on the surface of the annular guide belt, frictional contact occurs between the handrail belt and the friction element when these protrusions are in the gap. The friction element does not rotate with the handrail belt's friction; it remains stationary, creating frictional resistance. This resistance acts on the lower section of the handrail belt, balancing the frictional force on the upper section and maintaining the stability of the force on both sections, thus ensuring overall tension balance.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort 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, and multiple inclined segments and horizontal segments are connected to form an inclined wave-shaped structure.

[0040] Specifically, the escalator in this embodiment has a four-wave structure, with four inclined sections: 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 sequentially to form a four-wave structure.

[0041] By connecting horizontal sections between adjacent inclined sections, the length of continuous incline can be shortened, thus forming a horizontal structure between two inclined sections. This improves the passenger experience, avoids prolonged incline and ascent, and reduces passenger stress and fatigue during the ride.

[0042] Reference Figure 1 , Figure 2As shown, this embodiment includes a handrail belt 2, which is arranged along the inclined and horizontal sections to form handrail structures on both sides of the escalator, and can automatically rise and fall with the escalator. The handrail belt 2 has a ring structure, and can be driven by two sets of drive mechanisms to rotate in a ring, forming two handrails on both sides of the escalator.

[0043] In this embodiment, the escalator has a four-wave structure, and the escalator's inclined length is relatively long, resulting in a corresponding increase in the length of the handrail belt 2. Driven by two sets of drive mechanisms, the smoothness and fluidity of the handrail belt 2's operation are improved. The two sets of drive mechanisms are located near the upper and lower ends of the handrail belt 2, respectively, and the handrail belt 2 is driven by bypassing both sets of drive mechanisms.

[0044] Reference Figures 2-4 As shown, the two drive mechanisms are the first drive mechanism 3 and the second drive mechanism 4. The first drive mechanism 3 is located at the lower inclined end near the handrail belt 2, and the second drive mechanism 4 is located at the upper inclined end near the handrail belt 2. Both drive mechanisms are located at the lower half of the handrail belt 2, which can drive the handrail belt 2 to operate. Since the two drive mechanisms are located near the upper and lower ends of the handrail belt 2, they can drive the handrail belt 2 stably.

[0045] Reference Figure 3 , Figure 4 As shown, the drive mechanism includes a drive wheel 31, which is driven to rotate by a driver. A portion of the handrail belt 2 can wrap around the drive wheel 31. Through frictional contact between the drive wheel 31 and the handrail belt 2, the handrail belt 2 can be driven to rotate. The drive wheel 31 is driven by a drive motor in conjunction with a transmission belt, thereby driving the handrail belt 2 to rotate.

[0046] In order to form a stable wrap angle on the outer periphery of the drive wheel 31, improve the contact stability between the drive wheel 31 and the handrail belt 2, provide a stable friction force effect, and thus drive the handrail belt 2 to operate stably.

[0047] Guide support frame 1 32 and guide support frame 2 33 are respectively provided on both sides of the drive wheel 31. Guide support frame 1 32 is equipped with several guide wheels 1 321, and guide support frame 2 33 is equipped with several guide wheels 2 331. Both guide wheels 1 321 and guide wheels 2 331 are used for the handrail belt 2 to pass around. Through the guidance of guide wheels 1 321 and guide wheels 2 331, the handrail belt 2 can be guided and limited, thereby forming a more stable and smooth direction, so that the handrail belt 2 and the drive wheel 31 have a more stable contact area, effectively driving and reducing slippage. Following the direction of the handrail belt 2 on both sides of the drive wheel 31, guide wheels 1 321 and guide wheels 2 331 are arranged in an arc shape, respectively guiding the rolling of the handrail belt 2 that passes around both sides of the drive wheel 31. Through the arc arrangement structure, the smoothness of the direction of the handrail belt 2 can be maintained.

[0048] Furthermore, the guide support frame 2 33 near the drive 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, the contact area with the handrail belt 2 is increased, thereby improving the stability of the transmission.

[0049] The guide support frame 233 is located between the two sets of drive mechanisms. Figure 3 This is a structural schematic diagram of the first drive mechanism at point 3. Figure 3 The middle guide support frame 233 is located on the right side of the diagram; Figure 4 This is a structural diagram of the second drive mechanism at point 4. Figure 4 The second guide support frame 33 is located on the left side of the figure, and both sets of guide support frames 33 are located near the middle of the drive mechanism.

[0050] Each drive mechanism is equipped with an annular guide belt 5, which wraps around the outside of each guide wheel 331. On the side closest to the handrail belt 2, it forms an arc-shaped linkage section 501. The side facing away from the handrail belt 2 is tensioned by a tension wheel 332, ensuring the annular guide belt 5 remains flat and taut. (Refer to...) Figure 5 As shown, in this embodiment, the specific structure of the guide support frame 33 in the first drive mechanism 3 will be described.

[0051] The guide belt 5 passes around the guide wheels 331 at the arc-shaped linkage section 501, and the section facing away from the guide wheels 331 is the tension section 502. During operation, the handrail belt 2 passes around the arc-shaped linkage section 501 of the guide belt 5, forming a smooth arc-shaped fit and a stable contact. Compared to direct contact with the guide wheels 331, this improves the smoothness of the handrail belt 2 when passing through.

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

[0053] A protrusion 51 is integrally connected to the outer side of the annular guide belt 5. The protrusion 51 protrudes from the outer surface of the annular guide belt 5, meaning that the overall thickness of the annular guide belt 5 will increase at the corresponding position of the protrusion 51. The material of the protrusion 51 is the same as that of the annular guide belt 5, and it can also conform to the annular movement of the annular guide belt 5, ensuring the smoothness of the annular guide belt 5 during the winding process.

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

[0055] During the operation of the annular guide belt 5 and the handrail belt 2, when the protrusion 51 of the annular guide belt 5 is not at the gap 600, the annular guide belt 5 contacts the corresponding guide wheel 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 frictional obstruction is formed between the friction member 6 and the handrail belt 2.

[0056] When the protrusion 51 of the annular guide belt 5 is at the gap 600, the protrusion 51 also enters the gap 600. The annular guide belt 5, the handrail belt 2, and the protrusion 51 overlap each other, as shown in the reference. Figure 6 , Figure 7 As shown, the thickness after stacking exceeds the gap size of 600, which causes frictional contact between the handrail belt 2 and the friction component 6. The friction component 6 does not rotate with the friction of the handrail belt 2; it remains stationary, and the two form frictional resistance.

[0057] Reference Figure 2 As shown, during operation, the handrail belt 2 is partially located on the upper side of the handrail (upper section 201) and partially on the lower side (lower section 202). In the upper section 201, because passengers often lie prone, they experience pressure and significant frictional contact with the support frame, resulting in substantial frictional resistance. On the lower section 202, the guide wheels provide rolling contact, leading to a larger resistance difference between the upper and lower sections, thus creating a difference in tension.

[0058] Through the superposition of the protrusions 51 and the friction blocking of the friction element 6, intermittent frictional resistance can be generated on the handrail belt 2. Moreover, the guide support frame 33 is located on the lower section 202 of the handrail belt 2, and the friction force of the handrail belt 2 is located between the two sets of drive mechanisms, thus forming a frictional limiting effect on the lower section 202 of the handrail belt 2. By limiting the friction on the lower section 202, the frictional force on the upper section 201 of the handrail belt 2 is balanced, maintaining the force stability of the upper section 201 and the lower section 202 of the handrail belt 2, and keeping the overall tension of the handrail belt 2 balanced.

[0059] Reference Figure 6 As shown, the two sides of the protrusion 51 and the surface of the armrest 2 are smoothly transitioned through the transition portion 52. The thickness of the transition portion 52 gradually decreases in the direction away from the protrusion 51, thus forming a smooth direction and avoiding excessive jerking when the protrusion 51 comes into contact.

[0060] Example 2

[0061] This embodiment discloses a continuous multi-wave escalator, based on the above embodiment, and with reference to... Figures 9-11 Please provide a detailed explanation.

[0062] In this embodiment, the friction element 6 adopts a wheel-type structure and a unidirectional rotation structure. That is, in the working state, the handrail belt 2 contacts the friction element 6 for transmission, and the friction element 6 can remain stationary, forming frictional resistance on the handrail belt 2.

[0063] Reference Figure 9 As shown, the friction component 6 includes a friction wheel 60 and a support shaft 61. The support shaft 61 is fixed to the guide support frame 33, and the friction wheel 60 is rotatably connected to the outside of the support shaft 61 and achieves unidirectional transmission and limiting through a ratchet mechanism.

[0064] The ratchet mechanism enables unidirectional transmission control of the friction wheel 60. (Refer to...) Figure 9 As shown, this structure, installed on guide support frame 23, is mainly suitable for elevators traveling in the upward direction. Specifically, the upper section 201 of the handrail belt 2 is inclined upwards, while the lower section 202 is inclined downwards. The friction wheel 60 can rotate counterclockwise, and its clockwise rotation is limited by the ratchet structure.

[0065] specifically refer to Figure 9As shown, the support shaft 61 is in a fixed installation state, while the friction wheel 60 is rotatably connected to the outer periphery of the support shaft 61. When the ratchet mechanism is not in action, the friction wheel 60 can rotate smoothly, forming a structure similar to a bicycle hub. A ring sleeve 62 is coaxially fixedly installed on the side of the friction wheel 60, and a fixing plate 63 is coaxially fixedly installed on the outer periphery of the support shaft 61. The fixing plate 63 and the ring sleeve 62 are ring-shaped, with the ring sleeve 62 fitting on the outside, forming an annular space 64 between them. The ratchet mechanism is installed between the fixing plate 63 and the ring sleeve 62. A pulley 92 is formed on the outer periphery of the ring sleeve 62.

[0066] Specifically, a second ratchet portion 67 is integrally formed on the inner circumference of the ring 62, forming a ring-shaped distribution 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 outward-facing ratchet portion 66, forming another portion of the ratchet teeth. The ratchet portion 66 and the second ratchet portion 67 cooperate to achieve ratchet transmission. A stop block 68 is provided on the side of the linkage tooth 65 facing the clockwise direction. The stop block 68 is fixed to the fixed disk 63 and can block the linkage tooth 65, thus forming a one-way block when the friction wheel 60 rotates clockwise. When the friction wheel 60 rotates counterclockwise, the linkage tooth 65 can be deflected and repositioned, allowing the linkage tooth 65 to rotate smoothly.

[0067] During the downward movement of the lower section 202 of the handrail belt 2, the handrail belt 2 is lifted by the protrusion 51. When the handrail belt 2 comes into contact with the friction wheel 60, the handrail belt 2 and the friction wheel 60 make frictional contact. The friction wheel 60 will remain stationary. The friction wheel 60 can form a frictional resistance on the handrail belt 2 to counteract the frictional resistance on the upper section 201 of the handrail belt 2.

[0068] Since the friction contact between the handrail belt 2 and the friction wheel 60 is mainly sliding friction, it will generate slight friction on the surface of the friction wheel 60. If the contact is in the same position for a long time, the friction wheel 60 will experience greater wear in some areas.

[0069] A linkage wheel 7 is rotatably connected to the guide support frame 2 33. The linkage wheel 7 can rotate freely and is located above the guide wheel 321. A gap 2 is formed between the linkage wheel 7 and the corresponding guide wheel 321. The sum of the thicknesses of the annular guide belt 5 and the handrail belt 2 is less than the width of the gap 2; the sum of the thicknesses of the annular guide belt 5, the handrail belt 2, and the protrusion 51 is greater than the width of the gap 2.

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

[0071] The guide support frame 23 is rotatably connected to the linkage wheel 2 8, which is located above the linkage wheel 1 7. The linkage wheel 2 8 and the friction component 6 are connected by a transmission belt 9. The linkage wheel 2 8 is coaxially fixedly mounted with pulley 1 91, and the friction wheel 60 is coaxially fixedly mounted with pulley 2 92. The pulley 1 91 and pulley 2 92 are connected 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 7 can be adjusted up and down. Specifically, a vertically oriented groove 72 can be opened at the guide support frame 33. A slider 71 is slidably installed in the groove 72. The slider 71 can slide up and down along the groove 72, thereby enabling the linkage wheel 7 to also have a certain vertical movement stroke.

[0073] When the first linkage wheel 7 is located on the lower side of the stroke, that is, when the protrusion 51 of the annular guide belt 5 is not in the second gap, the lower side of the first linkage wheel 7 is in contact with the annular guide belt 5, and the upper side of the first linkage wheel 7 is separated from the second linkage wheel 8. The second linkage wheel 8 is not subjected to the force of the first linkage wheel 7 and does not rotate. The friction wheel 60 also does not rotate.

[0074] When the protrusion 51 on the outer side of the annular guide belt 5 passes under the linkage wheel 7, the thickness of the annular guide belt 5, the protrusion 51, and the handrail belt 2 overlaps, increasing the thickness beyond the original width of the gap. This allows the linkage wheel 7 to adjust upwards. After the linkage wheel 7 adjusts upwards, it drives the linkage wheel 8 to rotate. Simultaneously, the linkage wheel 8 and the friction wheel 60 will also generate mutual transmission, causing the friction wheel 60 to rotate counterclockwise. During this rotation, the ratchet mechanism does not limit the movement of the friction wheel 60, allowing it to rotate through a certain angle. This changes the position of the friction wheel 60 relative to the handrail belt 2, preventing the friction wheel 60 from rubbing against the same position for a long time and avoiding excessive wear in certain 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 embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
