Description

Technical Field

[0001] This utility model relates to the technical field of boarding bridge equipment, and in particular to a boarding bridge transfer device. Background Technology

[0002] Boarding bridges are important passageways connecting airport terminals and aircraft doors. They are large in size and extremely heavy. When maintaining, repairing, or replacing key load-bearing structures such as the columns of boarding bridges, temporary support devices must be used to provide safe and reliable support from below to ensure construction safety and the structural stability of the boarding bridge itself.

[0003] Existing boarding bridge ...

[0004] More importantly, even if the boarding bridge is roughly aligned horizontally, its top support surface is usually a fixed horizontal plane. However, the bottom structure of the boarding bridge is complex, and its supported surface may not be completely horizontal but rather have a certain angle of inclination. When a flat support surface presses against an inclined supported surface, the two cannot achieve full contact, resulting in point contact or line contact. This leads to excessive local pressure, which may not only damage the structure of the boarding bridge but also increase the risk of slippage and instability due to uneven force. This makes the existing boarding bridge boarding bridge boarding bridge devices generally suffer from defects such as single structural function and poor adaptability. They cannot make precise fine-tuning in terms of horizontal position, vertical height, and contact angle, and it is difficult to form a stable support interface with uniform force distribution with the bottom of the boarding bridge. This poses a safety hazard to the entire boarding bridge boarding bridge operation.

[0005] Therefore, this utility model proposes a boarding bridge transfer device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology, such as the boarding bridge transfer device having a single structural function and being unable to make precise fine adjustments in horizontal position and support angle, resulting in difficulty in forming a stable and fully fitted support interface with the bottom of the boarding bridge, which poses safety hazards, this utility model aims to provide a boarding bridge transfer device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a boarding bridge transfer device, including: a base plate, a steel frame assembly vertically fixed to the upper surface of the base plate, a bearing plate assembly horizontally fixed to the top of the steel frame assembly, and a support assembly.

[0008] The support plate assembly includes a support plate body, the upper surface of which is provided with a sliding groove for the support assembly to slide, and a locking groove is also provided on the inner wall of the sliding groove.

[0009] The support component is the core innovation of this solution. It includes a base, a jack body, and a wedge-shaped steel plate. The bottom of the base is integrally formed with a locking block. The jack body is vertically set on the upper surface of the base, and the wedge-shaped steel plate is connected to the top of the jack body at an adjustable angle.

[0010] In terms of overall assembly, the support component is slidably connected to the slide groove of the bearing plate body through its base. At the same time, the locking block at its bottom forms a sliding locking relationship with the locking groove in the slide groove, thus forming a stable support unit that is both adjustable and lockable.

[0011] Preferably, in order to reliably lock the angle of the wedge-shaped steel plate, the upper part of the jack body is provided with a first mounting hole, the wedge-shaped steel plate is provided with a second mounting hole, and the support assembly further includes a second high-strength bolt, which passes through the first mounting hole and is threadedly connected to the second mounting hole.

[0012] Preferably, in order to construct a robust load-bearing structure, the steel frame assembly includes multiple load-bearing steel columns, the bottom ends of which are fixedly connected to the base plate by a first high-strength bolt, forming the main vertical load-bearing frame.

[0013] Preferably, in order to further improve the structural stability and resistance to lateral deformation of the steel frame assembly, the steel frame assembly also includes multiple diagonal bracing steel plates, which are inclinedly welded between adjacent load-bearing steel columns to form multiple stable triangular support structures.

[0014] Preferably, as a further strengthening structure, the steel frame assembly also includes a horizontal support steel column, which is horizontally fixed to the middle of the diagonal brace steel plate to enhance the rigidity of the diagonal brace steel plate itself and prevent it from buckling under pressure.

[0015] Preferably, also as a reinforcing structure, when the two diagonal bracing steel plates form an intersecting layout, the steel frame assembly also includes a central column, which is vertically located at the intersection of the two intersecting diagonal bracing steel plates to form a stable spatial node to optimize stress distribution.

[0016] Preferably, in order to securely fix the entire device to the ground foundation, the base plate is provided with a connection hole for connecting and fixing the base plate to the concrete foundation platform through the connection hole.

[0017] Preferably, the bearing plate body is a rectangular plate structure, which not only facilitates processing and manufacturing, but also provides convenience for the sliding and layout of the support components.

[0018] This utility model has the following beneficial effects: 1. This utility model solves the technical problems of existing boarding bridge replacement devices being difficult to align precisely and unable to adapt to the sloping bottom of the boarding bridge, resulting in unstable support and uneven force distribution. It can move in the groove of the bearing plate and lift the wedge-shaped steel plate at the top of the plate by the jack body.

[0019] 2. This utility model solves the safety hazard of horizontal sliding or displacement of the support component under huge pressure by setting a locking block at the bottom of the base of the support component and setting a matching locking groove in the slide groove of the bearing plate. It allows horizontal adjustment while providing reliable locking, effectively preventing the support component from moving unexpectedly when bearing load, and ensuring the long-term support stability of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 4 This utility model provides a boarding bridge transfer device, which aims to solve the problems of unstable support and uneven force on the contact surface in the existing boarding bridge transfer device.

[0025] like Figure 1 and Figure 2 As shown, the boarding bridge's transfer device includes a base plate 1 and a steel frame assembly 2 vertically fixed to the upper surface of the base plate 1. The base plate 1 has connection holes 5 for connecting and fixing the entire device to a concrete foundation. The steel frame assembly 2 provides the main load-bearing support. A load-bearing plate assembly 3 is horizontally fixed to the top of the steel frame assembly 2. The load-bearing plate assembly 3 includes a load-bearing plate body 301 serving as an installation platform. A groove 303 is formed on the upper surface of the load-bearing plate body 301, and a slot 302 is formed on the inner wall of the groove 303. The device also includes a support assembly 4, which is slidably connected within the groove 303 to achieve a horizontal position. For precise adjustment, the support assembly 4 includes a base 401, a jack body 403, and a wedge-shaped steel plate 404. The jack body 403 is vertically mounted on the upper surface of the base 401 to provide vertical lifting adjustment. The wedge-shaped steel plate 404 is connected to the top of the jack body 403 at an adjustable angle to adapt to the inclined surface at the bottom of the boarding bridge. The bottom of the base 401 has an integrally formed locking block 402. The shape and size of the locking block 402 are adapted to the locking groove 302. When the support assembly 4 slides along the sliding groove 303, the locking block 402 and the locking groove 302 form a sliding engagement to ensure that the support assembly 4 will not slide unexpectedly after being adjusted to the correct position.

[0026] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment lies in the specific sliding, snapping and locking structure formed between the support component 4 and the carrier plate component 3.

[0027] Please refer to the following carefully. Figure 3 and Figure 4 The core structure will be described in detail below: The support assembly 4 includes a base 401, a jack body 403, and a wedge-shaped steel plate 404. The bottom of the base 401 is integrally formed with a locking block 402. The upper part of the jack body 403 is provided with a first mounting hole 406, and the wedge-shaped steel plate 404 is correspondingly provided with a second mounting hole 407. The support assembly 4 also includes a second high-strength bolt 405. After the angle of the wedge-shaped steel plate 404 is adjusted to the correct position, the second high-strength bolt 405 passes through the first mounting hole 406 and is threadedly connected to the second mounting hole 407, thereby firmly locking the wedge-shaped steel plate 404 to the top of the jack body 403. This connection method ensures that the angle of the wedge-shaped steel plate 404 will not change during the load-bearing process.

[0028] Meanwhile, a groove 303 is correspondingly provided on the upper surface of the support plate body 301, and a slot 302 is also provided on the inner wall of the groove 303. In the assembled state, the base 401 of the support component 4 is placed in the groove 303 of the support plate body 301, and the bottom of the locking block 402 is embedded and locked in the slot 302. This cooperation structure between the locking block 402 and the slot 302 allows the support component 4 to be adjusted in position along the length of the groove 303, while providing a reliable anti-slip locking effect. This ensures that the support component 4 will not undergo accidental horizontal displacement when subjected to huge pressure from the boarding bridge, thus ensuring the stability and safety of the entire boarding process.

[0029] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to further enhance the structural rigidity and stability of the steel frame assembly 2, please refer to... Figure 3 The steel frame assembly 2 includes multiple load-bearing steel columns 201. The bottom ends of the multiple load-bearing steel columns 201 are fixedly connected to the upper surface of the base plate 1 by first high-strength bolts 205, thereby forming the main vertical load-bearing structure.

[0030] As a further optimization of the structure of the steel frame assembly 2, the steel frame assembly 2 also includes multiple diagonal bracing steel plates 202. Each diagonal bracing steel plate 202 is inclinedly welded between two adjacent load-bearing steel columns 201. By constructing a triangular stable structure, the ability of the entire steel frame assembly 2 to resist lateral deformation is improved.

[0031] Based on the diagonal bracing steel plate 202, the steel frame assembly 2 may also include a horizontal support steel column 203, which is horizontally fixed to the middle of the diagonal bracing steel plate 202 to further enhance the rigidity of the diagonal bracing steel plate 202 and prevent it from buckling under pressure.

[0032] Similarly, based on the diagonal bracing steel plate 202, when the two diagonal bracing steel plates 202 intersect, the steel frame assembly 2 may also include a central column 204. The central column 204 is vertically located at the intersection of the two intersecting diagonal bracing steel plates 202, forming a spatial node, which makes the stress transmission path more diversified, thereby further enhancing the overall structural stability and load-bearing potential of the steel frame assembly 2.

[0033] As a preferred embodiment, the support plate body 301 has a rectangular plate structure, which is beneficial for processing and manufacturing as well as the layout and installation of the support components 4.

[0034] The working principle of the boarding bridge check-in device of this utility model is as follows: When carrying out boarding bridge replacement work, the entire device is first firmly installed on the concrete foundation platform of the airport through the connection holes 5 on the base plate 1. The steel frame assembly 2 provides a stable foundation support for the entire device with its high-strength structure.

[0035] Subsequently, based on the specific support point location at the bottom of the boarding bridge, the operators manually pushed the support component 4, causing its base 401 to slide horizontally along the slide groove 303 on the upper surface of the bearing plate body 301. Since the locking block 402 at the bottom of the base 401 and the locking slot 302 in the slide groove 303 always remain engaged, the smoothness of the movement and the accuracy of the positioning are ensured.

[0036] Once the horizontal position of the support component 4 is determined, observe the tilt angle of the bottom of the boarding bridge and adjust the angle of the wedge steel plate 404 accordingly so that its top surface can be completely parallel and in contact with the bottom surface of the boarding bridge. Then, operate the jack body 403 to lift its top rod upwards until the wedge steel plate 404 is in complete contact with the bottom surface of the boarding bridge and a certain preload is applied. Finally, pass the second high-strength bolt 405 through the first mounting hole 406 and the second mounting hole 407 and tighten it to completely lock the angle of the wedge steel plate 404. Through the lifting of the jack body 403, the angle adaptation of the wedge steel plate 404, and the locking synergy of the locking block 402 and the locking groove 302, this utility model solves the problems of unstable support and uneven force on the contact surface caused by the single function of the support structure in the prior art.

[0037] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be determined by the protection scope of the claims.
