Description

Technical Field

[0001] This invention belongs to the field of elevator technology and relates to a self-correcting backpack elevator. Background Technology

[0002] In existing technologies, backpack elevators are widely used in retrofitting existing buildings or in space-constrained locations due to their compact structure and flexible installation. These elevators typically use a single-sided guide rail to support the car, and a connecting mechanism movably connects the car to the guide rail to achieve vertical operation. However, due to the offset of the car's center of gravity and uneven distribution of external loads, a forward tilting moment is easily generated during operation, causing the car to tilt relative to the guide rail. This tilt not only exacerbates the non-uniform contact and friction between the sliding guide shoe and the guide rail, but also causes significant shaking and operating noise, seriously affecting passenger comfort and system stability.

[0003] Therefore, there is an urgent need for a backpack elevator structure that can achieve self-correction to effectively counteract the bending moment generated during operation. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a self-correcting backpack elevator, comprising: The guide rail is set vertically; The car includes a gantry frame and a support frame, wherein the support frame is perpendicularly connected to the gantry frame; A connecting mechanism movably connects the gantry frame to the guide rail. The connecting mechanism includes a sliding guide shoe, a first adjusting component, and a second adjusting component. The sliding guide shoe is connected to the gantry frame and is sleeved on the guide rail. Both the first adjusting component and the second adjusting component are connected to the gantry frame and slide in cooperation with the side wall of the guide rail. The first adjusting component is located on the side of the guide rail closer to the support frame, and the second adjusting component is located on the side of the guide rail away from the support frame.

[0005] In the aforementioned self-correcting backpack elevator, both the first adjustment component and the second adjustment component include a wheel axle and a pin. One end of the pin is connected to the gantry frame, and the middle part of the wheel axle is rotatably connected to the pin.

[0006] In the aforementioned self-correcting backpack elevator, the first adjustment component and the second adjustment component further include two contact members, which are disposed at both ends of the axle.

[0007] In the aforementioned self-correcting backpack elevator, the contact element is configured as a rotating wheel, which is rotatably connected to the axle.

[0008] In the aforementioned self-correcting backpack elevator, a contact layer is provided around the rotating wheel, and the contact layer is made of hard rubber.

[0009] In the aforementioned self-correcting backpack elevator, the first adjustment component and the second adjustment component further include a limiting member, which is disposed on the pin and is used to axially limit the axle from both sides.

[0010] In the aforementioned self-correcting backpack elevator, the limiting member is a retaining ring, which is detachably mounted on the pin.

[0011] In the aforementioned self-correcting backpack elevator, the car further includes a suspension point located in the middle section of the gantry frame.

[0012] In the aforementioned self-correcting backpack elevator, the car further includes a diagonal brace, one end of which is connected to the gantry frame, and the other end of which is connected to the end of the support frame away from the gantry frame.

[0013] In the aforementioned self-correcting backpack elevator, the sliding guide shoe is disposed adjacent to both the first adjustment component and the second adjustment component.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: By contacting the first and second adjustment components with the guide rail, the excessive contact between the sliding guide shoe and the guide rail caused by the car tilting forward is reduced, thereby alleviating the shaking and noise generated during the operation of the backpack elevator and effectively improving the stability of the entire backpack elevator during operation; Since the wheel axle can rotate around the pin shaft according to the tilt of the guide rail, it provides a stable guiding reaction force through continuous contact with the guide rail, thus the entire car carried by the gantry frame can maintain an ideal vertical posture and will not tilt or shake due to local defects in the guide rail; By transferring the contact function to the dedicated contact components at both ends of the wheel axle, the direct contact between the guide rail and the middle section of the wheel axle is effectively isolated, avoiding unexpected wear of key connection parts. At the same time, the symmetrical layout of the double contact components can also form a stable two-point support, making the reaction force distribution more uniform. Attached Figure Description

[0025] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.

[0026] like Figures 1-4 As shown, a self-correcting backpack elevator includes: a guide rail 1, a car 2, and a connecting mechanism 3.

[0027] The guide rail 1 is vertically arranged.

[0028] The car 2 includes a gantry frame 21 and a support frame 22, with the support frame 22 being vertically connected to the gantry frame 21.

[0029] The connecting mechanism 3 movably connects the gantry frame 21 to the guide rail 1. The connecting mechanism 3 includes a sliding guide shoe 31, a first adjusting component 32, and a second adjusting component 33. The sliding guide shoe 31 is connected to the gantry frame 21 and is sleeved on the guide rail 1. The first adjusting component 32 and the second adjusting component 33 are both connected to the gantry frame 21 and slide in cooperation with the side wall of the guide rail 1. The first adjusting component 32 is located on the side of the guide rail 1 closer to the support frame 22, and the second adjusting component 33 is located on the side of the guide rail 1 away from the support frame 22.

[0030] Specifically, in the suspended state, the support frame 22 drives the gantry frame 21 to generate a bending moment M relative to the guide rail 1. At this time, the gantry frame 21 drives the first adjustment component 32, the second adjustment component 33 and the sliding guide shoe 31 to rotate, thereby contacting the guide rail 1 to generate reaction forces F and -F to form a reverse bending moment -M, which in turn cancels out the bending moment M, thereby realizing the self-correction of the entire backpack elevator.

[0031] In this embodiment, by adjusting the first adjustment component 32 and the second adjustment component 33 in contact with the guide rail 1, the excessive contact between the sliding guide shoe 31 and the guide rail 1 caused by the forward tilting of the car 2 is reduced, thereby alleviating the shaking and noise generated during the operation of the backpack elevator and effectively improving the stability of the entire backpack elevator during operation.

[0032] like Figures 1-4 As shown, based on the above embodiments, both the first adjustment component 32 and the second adjustment component 33 include a wheel axle 34 and a pin 35. One end of the pin 35 is connected to the gantry frame 21, and the middle part of the wheel axle 34 is rotatably connected to the pin 35.

[0033] Specifically, the rotatable connection between the wheel axle 34 and the pin 35 gives the adjustment assembly a certain degree of adaptive rotational freedom in the horizontal plane. When the car 2 runs along the guide rail 1, if the guide rail 1 is slightly tilted, bent or uneven due to manufacturing error, installation deviation or long-term use, the wheel axle 34 in the first adjustment assembly 32 and the second adjustment assembly 33 can automatically adjust its angle around the pin 35 so that the wheel axle 34 always fits the direction of the guide rail 1.

[0034] In this embodiment, since the axle 34 can rotate around the pin 35 according to the tilt of the guide rail 1, it continuously contacts the guide rail 1 to provide a stable guiding reaction force. As a result, the entire car 2 carried by the gantry frame 21 can maintain an ideal vertical posture and will not tilt or sway due to local defects in the guide rail 1.

[0035] like Figures 1-4 As shown, based on the above-described embodiments, the first adjustment component 32 and the second adjustment component 33 further include two contact members, which are disposed at both ends of the axle 34.

[0036] Specifically, two contact elements are provided at both ends of the axle 34, so that the actual contact area with the side wall of the guide rail 1 is limited to the end of the axle 34. Since the middle part of the axle 34 needs to be fitted with a pin 35 to achieve a rotatable connection with the gantry frame 21, and this part has a through hole, the mechanical strength is relatively low. If it directly rubs or squeezes against the side wall of the guide rail 1, it is very easy to cause material fatigue and accelerated wear due to local stress concentration.

[0037] In this embodiment, by transferring the contact function to dedicated contact members at both ends of the wheel axle 34, the direct contact between the guide rail 1 and the middle section of the wheel axle 34 is effectively isolated, avoiding unexpected wear of key connection parts. At the same time, the symmetrical layout of the dual contact members can also form a stable two-point support, making the reaction force distribution more uniform.

[0038] like Figures 1-4 As shown, based on the above embodiment, the contact element is configured as a rotating wheel 36, which is rotatably connected to the wheel axle 34.

[0039] In this embodiment, the contact element is configured to change the original sliding contact of the rotating wheel 36 to rolling contact, which greatly reduces the resistance of the first adjustment component 32 and the second adjustment component 33 as a whole, and also reduces the wear of the side wall of the guide rail 1 and the surface of the rotating wheel 36, effectively extending the service life of the first adjustment component 32 and the second adjustment component 33.

[0040] like Figures 1-4 As shown, based on the above embodiment, a contact layer is provided around the rotating wheel 36, and the contact layer is made of hard rubber.

[0041] Specifically, using hard rubber as the contact medium between the rotating wheel 36 and the side wall of the guide rail 1 can effectively buffer the instantaneous vibration caused by minor unevenness or seams of the guide rail 1 during elevator operation, while maintaining sufficient support rigidity.

[0042] In this embodiment, the elastic buffering effect of the hard rubber material not only significantly reduces the vibration and noise generated by the connection mechanism 3 and the guide rail 1, but also avoids the surface fatigue damage that may be caused by the direct contact between metals, thus providing good protection for the guide rail 1 and extending the service life of the guide rail 1 itself.

[0043] like Figures 1-4 As shown, based on the above-described embodiments, the first adjustment component 32 and the second adjustment component 33 further include a limiting member, which is disposed on the pin 35 and is used to axially limit the axle 34 from both sides.

[0044] Specifically, the limiting component is fixed on the pin 35, forming a physical block on both sides of the wheel axle 34, which can effectively prevent the wheel axle 34 from axially shifting due to vibration or impact during elevator operation, thereby causing the rotating wheel 36 to partially or completely separate from the side wall of the guide rail 1.

[0045] In this embodiment, the wheel axle 34 is axially limited by the setting of the limiting member, which not only ensures that the wheel axle 34 is always in the precise position, so that the rotating wheel 36 can continuously and reliably fit against the side wall of the guide rail 1, but also prevents the wheel axle 34 from colliding or interfering with other structures of the gantry frame 21.

[0046] like Figures 1-4 As shown, based on the above embodiment, the limiting member is set as a retaining ring 37, which is detachably mounted on the pin 35.

[0047] In this embodiment, the snap ring 37 itself has a simple structure and low manufacturing cost. It can achieve effective axial positioning of the wheel axle 34 without additional fasteners. If the snap ring 37 fails due to fatigue after long-term operation of the equipment, the rotating wheel 36 wears and needs to be replaced, or the position of the wheel axle 34 needs to be adjusted, the maintenance personnel can quickly disassemble the old snap ring 37 to make the above adjustments or replacements, which greatly reduces the maintenance difficulty and downtime.

[0048] like Figures 1-4 As shown, based on the above embodiment, the car 2 also includes a suspension point 23, which is located in the middle section of the gantry frame 21.

[0049] In this embodiment, the suspension point 23 is located in the middle section of the gantry frame, which helps to reduce the difference in bending moment between the upper and lower parts of the gantry frame 21. Furthermore, during the self-correction process of the car 2, it will not interfere with the suspension point located in the middle section of the gantry frame 21, thus ensuring the stability of the suspension system.

[0050] like Figures 1-4 As shown, based on the above embodiment, the car 2 further includes a diagonal tie rod 24, one end of which is connected to the gantry frame 21, and the other end of which is connected to the end of the support frame 22 away from the gantry frame 21.

[0051] Specifically, one end of the diagonal tie rod 24 is connected to the gantry frame 21, and the other end is connected to the end of the support frame 22 away from the gantry frame 21, thereby forming a stable triangular structure among the gantry frame 21, the support frame 22 and the diagonal tie rod 24, which significantly improves the structural rigidity of the overall frame of the car 2.

[0052] In this embodiment, the diagonal tie rod 24 is not only a key component that significantly enhances the overall rigidity of the car 2, but also ensures that the car 2 will not interfere with the landing door sill after maintaining an ideal vertical state following the self-correction implementation.

[0053] like Figures 1-4 As shown, based on the above embodiment, the sliding guide shoe 31 is arranged adjacent to the first adjustment component 32 and the second adjustment component 33 respectively.

[0054] In this embodiment, the sliding guide shoe 31 is compactly adjacent to the first adjustment component 32 and the second adjustment component 33. Since the first adjustment component 32 and the second adjustment component 33 are in direct contact with the side wall of the guide rail 1, under the synergistic effect of the self-correction function, the closer the sliding guide shoe 31 is to the first adjustment component 32 and the second adjustment component 33, the smaller its tilt relative to the guide rail 1, thereby ensuring that the elevator maintains high precision, low disturbance and high reliability vertical operation performance throughout the entire journey.
