Description

Technical Field

[0001] This disclosure relates to the field of escalator technology, and more specifically, to an escalator and its stabilization device. Background Technology

[0002] Escalators experience periodic swaying during operation due to factors such as pedestrian movement and mechanical transmission. Especially during peak hours, the low-frequency swaying generated by the truss structure can cause significant discomfort to passengers.

[0003] In related technologies, to reduce escalator swaying, hydraulic dampers need to be installed in the on-site concrete foundation or load-bearing walls of the building. However, some older buildings cannot install hydraulic dampers due to the lack of pre-embedded fixing points. Furthermore, after installing hydraulic dampers, there are still shortcomings such as maintenance difficulties and poor stability due to the inability of the hydraulic dampers to adapt to different escalator stops.

[0025] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0030] Figure 1 A schematic perspective view of the truss is shown. Figure 2 A schematic cross-sectional view of a stabilizing device according to an embodiment of the present disclosure is shown.

[0031] like Figures 1-2As shown, this disclosure provides a stabilizing device for an escalator. The stabilizing device can be installed at the bottom of the escalator's truss 6. The escalator's truss 6 is the overall skeleton of the escalator, used to support the weight of the steps and passengers. The truss 6 is made of a robust metal material, possessing sufficient strength and stability to ensure that the escalator can withstand the required forces and gravity during operation. Specifically, as... Figure 1 As shown, the truss 6 may include two sets of oppositely arranged upper chords 61, two sets of oppositely arranged lower chords 62, a plurality of longitudinal support beams 63 for connecting the upper chords 61 and lower chords 62 located on the same side, and a base plate 64 for connecting the two sets of lower chords 62. The upper chords 61 can be installed on top of the lower chords 62 via the longitudinal support beams 63.

[0032] The stabilizing device can stabilize the truss 6 and reduce its swaying when it is subjected to external forces (such as passenger movement or mechanical transmission). The stabilizing device may include a housing 1, a slider 2, and at least one elastic part 3. The two connecting ends 11 of the housing 1 for connecting to the truss 6 can be in the lateral direction of the truss 6 (e.g., ...). Figure 1 and Figure 2 The two connecting ends 11 are respectively installed between the bottoms of the two longitudinal support beams 63 of the truss 6, so that the stabilizing device can be installed at the bottom of the truss 6, even if the stabilizing device is located on the side of the base plate 64 away from the upper chord 61. Since the bottom of the truss 6 can have a large accommodation space after the escalator is installed, it is convenient to maintain and repair the stabilizing device.

[0033] Furthermore, the slider 2 is slidably disposed within the housing 1 in the lateral direction. Each elastic part 3 is connected between the end of the slider 2 and the connecting end 11 of the housing 1. The elastic part 3 can extend in the lateral direction. When the slider 2 slides relative to the connecting end 11 of the housing 1, the slider 2 applies a force to the elastic part 3, causing the elastic part 3 to deform.

[0034] Furthermore, in response to the truss 6 being swayed by an external force, the housing 1 sways along with the truss 6, and the slider 2 maintains its original state based on inertia. As a result, the slider 2 will slide relative to the connecting end 11 of the housing 1 within the housing 1, causing the elastic part 3 to deform. At the same time, the elastic restoring force of the elastic part 3 will push the slider 2 to move in the opposite direction to the swaying of the truss 6, so as to prevent the truss 6 from swaying.

[0035] According to the embodiments of this disclosure, by placing the housing 1 at the bottom of the truss 6, the housing 1 can sway with the truss 6. Furthermore, since the stabilizing device is located at the bottom of the truss 6, maintenance or repair of the stabilizing device does not require disassembly of the escalator side panels, improving the convenience of maintenance or repair. By providing a slider 2 inside the housing 1 and connecting the slider 2 to the connection end 11 of the housing 1 via an elastic part 3, the kinetic energy of the relative sliding between the slider 2 and the housing 1 can be converted into the elastic potential energy of the elastic part 3. This allows the elastic part 3 to push the slider 2 in the opposite direction to the swaying of the truss 6 based on the elastic restoring force, thereby preventing the truss 6 from swaying and ensuring the stability of the escalator. The stabilizing device has a simple structure and low cost. By adjusting the number of stabilizing devices and their position at the bottom of the truss 6, the stabilizing effect of the stabilizing devices on the escalator can be flexibly adjusted, thereby meeting the stability requirements of different escalator stations.

[0036] like Figure 2 As shown, in some embodiments, the stabilizing device may further include a guide portion 4. The guide portion 4 may be disposed within the housing 1, extending laterally, and slidably engages with the slider 2. The slider 2 slides under the guidance of the guide portion 4. By providing the guide portion 4, the movement trajectory of the slider 2 can be restricted, preventing deviation or jamming during movement due to excessive clearance between the slider 2 and the housing 1, ensuring that the slider 2 slides only in the lateral direction. This reduces mechanical wear and improves the stabilizing efficiency and service life of the stabilizing device. The material of the guide portion 4 can be used to adjust the friction between the guide portion 4 and the slider 2, ensuring smooth contact between them.

[0037] like Figure 2 As shown, in some embodiments, the guide portion 4 may include an upper guide portion 41 and a lower guide portion 42. The upper guide portion 41 may be disposed on the upper side of the slider 2 and slide in cooperation with the upper side of the slider 2, that is, the upper guide portion 41 may be located between the upper side of the slider 2 and the inner wall of the housing 1. The lower guide portion 42 may be disposed on the lower side of the slider 2 and slide in cooperation with the lower side of the slider 2, that is, the lower guide portion 42 may be located between the lower side of the slider 2 and the inner wall of the housing 1. By providing the upper guide portion 41 and the lower guide portion 42, the slider 2 can be prevented from moving in the vertical direction (e.g., Figure 1 and Figure 2 The movement (as shown in the Y direction) causes the slider 2 to move laterally relative to the housing 1, thereby suppressing the swaying of the truss 6 in the lateral direction, that is, suppressing the left and right (e.g., as shown in the Y direction) of the truss 6. Figure 2(The slider 2 shown wobbles in the left-right direction). The upper guide portion 41 and the lower guide portion 42 can be constructed as a guide rail-like structure to guide the slider 2 to slide. The guide portion 4 and the outer contour of the slider 2 can match each other to form a concave-convex fit. For example, the upper guide portion 41 and the lower guide portion 42 can be respectively formed with grooves that match the upper side contour and the lower side contour of the slider 2. The slider 2 slides in the housing 1 based on the fit with the upper guide portion 41 and the lower guide portion 42.

[0038] In some embodiments, the guide portion 4 can be configured as an annular tubular structure. The slider 2 can pass through the guide portion 4, and the guide portion 4 can surround the slider 2. By making the guide portion 4 an annular tubular structure, the movement trajectory of the slider 2 can be prevented from deviating from the axis of the guide portion 4, ensuring that the energy generated by sliding is completely converted into the deformation of the elastic portion 3. By making the guide portion 4 an annular structure, the slider 2 can be protected from external dust or foreign matter intrusion, reducing long-term wear and extending the service life of the stabilizing device.

[0039] In some embodiments, only one elastic part 3 may be provided. The elastic part 3 is provided at one end of the slider 2, and the other end of the slider 2 may be at a certain distance from the connecting end 11 of the housing 1, so that when the slider 2 slides relative to the housing 1, the slider 2 does not contact the connecting end 11 of the housing 1.

[0040] like Figure 2 As shown, in some embodiments, two elastic parts 3 may be provided. The two elastic parts 3 are located at both ends of the slider 2, and respectively connect the ends of the slider 2 to the connecting ends 11 of the housing 1. By providing two elastic parts 3, the force balance of the slider 2 when sliding in the lateral direction can be ensured, thereby improving the sliding stability of the slider 2.

[0041] Figure 3 A schematic cross-sectional view of a stabilizing device according to another embodiment of the present disclosure is shown.

[0042] like Figure 3 As shown, in some embodiments, the slider 2 may include at least two sub-sliders 21 arranged sequentially in the transverse direction. A sub-elastic part 31 is provided between two adjacent sub-sliders 21. When the truss 6 is subjected to external force and the housing 1 follows the truss 6 in swaying, the sub-slider 21 maintains its original state based on inertia, thus the sub-slider 21 slides relative to the connecting end 11 of the housing 1 within the housing 1, causing the sub-elastic part 31 and the elastic part 3 to deform. Simultaneously, the elastic restoring force of the sub-elastic part 31 and the elastic part 3 pushes the sub-slider 21 to move in the opposite direction to the swaying of the truss 6, thereby preventing the truss 6 from swaying. The sub-elastic part 31 and the elastic part 3 can be elastic components such as springs. Since each sub-slider 21 independently generates inertial force based on its own mass, the response lag caused by the concentration of mass in the overall slider 2 is avoided, thereby improving stabilization efficiency.

[0043] like Figure 2 As shown, in some embodiments, the stabilizing device may further include two mounting portions 5. The two mounting portions 5 are symmetrically arranged at the bottom of the longitudinal support beam 63 and are respectively connected to the two connecting ends 11 of the housing 1. Figure 2 As shown, the housing 1 is mounted on the bottom of the truss 6 through two symmetrically arranged mounting parts 5. The swaying of the truss 6 can be synchronously transmitted to the housing 1 through the symmetrically arranged mounting parts 5, which can avoid the stabilizing device being subjected to force on one side and causing local stress concentration, thereby improving the stability of the stabilizing device.

[0044] like Figure 2 As shown, in some embodiments, each mounting portion 5 may include an L-shaped bracket 51 and a connector 52. One end of the L-shaped bracket 51 is connected to the side wall of the longitudinal support beam 63. The other end of the L-shaped bracket 51 extends to the bottom of the longitudinal support beam 63. One end of the connector 52 is detachably connected to the L-shaped bracket 51. The other end of the connector 52 is connected to the connecting end 11 of the housing 1. The L-shaped bracket 51 may include a first bend and a second bend. One end of the L-shaped bracket 51 may be characterized as the first bend. The other end of the L-shaped bracket 51 may be characterized as the second bend. The first bend may be connected to the side wall of the longitudinal support beam 63. The second bend may be connected to the first bend and used to install the connector 52. The first bend and the second bend may form an L-shape. The second bend may protrude from the base plate 64 of the truss 6 to provide installation space for installing the stabilizing device. By providing the mounting portion 5, the stabilizing device can be avoided from being directly installed on the thinner base plate 64, thereby improving the stability of the stabilizing device installation.

[0045] This disclosure also provides an escalator. The escalator may include a truss 6 and a plurality of stabilizing devices as described above. The truss 6 may include two sets of opposing upper chords 61, two sets of opposing lower chords 62, a plurality of longitudinal support beams 63 for connecting the upper chords 61 and lower chords 62 located on the same side, and a base plate 64 for connecting the two sets of lower chords 62. The longitudinal support beams 63 are disposed at the lower part of the upper chords 61. The plurality of stabilizing devices are respectively installed between the two longitudinal support beams 63 and located at different positions at the bottom of the truss 6 to meet the stability requirements of different stations of the escalator.

[0046] In some embodiments, the weight of the slider 2 in different stabilizing devices can be different. The stiffness of the elastic part 3 in different stabilizing devices can be different. Specifically, the stabilizing capabilities of different stabilizing devices can be different. By adjusting the weight of the slider 2 and / or the stiffness of the elastic part 3, the stabilizing devices can have different stabilizing capabilities. For example, at sites with greater swaying force, the slider 2 can be set to be heavier to provide greater inertial force, thereby better suppressing swaying. At sites with less swaying force, the slider 2 can be set to be lighter to provide a more sensitive response. At sites with lower swaying frequency or larger amplitude, the stiffness of the elastic part 3 can be set to be lower to allow greater deformation, absorb more energy, and provide a gentler damping effect. At sites with higher swaying frequency or requiring a fast response, the stiffness of the elastic part 3 can be set to be stronger to push the slider 2 faster and provide a stronger damping force.

[0047] The embodiments of this disclosure have been described above. However, these embodiments are for illustrative purposes only and are not intended to limit the scope of this disclosure. Although various embodiments have been described above, this does not mean that the measures in the various embodiments cannot be used advantageously in combination. The scope of this disclosure is defined by the appended claims and their equivalents. Various substitutions and modifications can be made by those skilled in the art without departing from the scope of this disclosure, and all such substitutions and modifications should fall within the scope of this disclosure.
