Description

Technical Field

[0001] This application relates to the field of aviation maintenance operation technology, specifically to a tire removal auxiliary device for boarding bridges. Background Technology

[0002] Currently, maintenance personnel often rely on tools such as rubber hammers and trolleys when replacing the wheels of boarding bridges, requiring multiple people to work together to complete the disassembly. This method has many drawbacks: limited operating space, poor tool compatibility, and uneven force on the tires during disassembly, which can easily cause equipment damage. Utility Model Content

[0003] The main objective of this application is to provide a tire removal assist device for boarding bridges, which aims to solve the aforementioned technical problems.

[0004] The technical solution adopted in this application is as follows:

[0005] A boarding bridge tire removal auxiliary device includes a main frame for holding the boarding bridge tire in place and a top screw rod disposed on the main frame and coaxial with the central axis of the boarding bridge tire. The top screw rod contacts the central axis of the boarding bridge tire, and the boarding bridge tire is pulled out by rotation using the traction of the top screw rod.

[0006] Optionally, the main frame includes a main frame beam, an auxiliary frame beam, and a connecting beam. The main frame beam and the auxiliary frame beam are connected alternately in pairs to form a square frame. There is one square frame at the top and one at the bottom. The connecting beam connects the two square frames.

[0007] Optionally, the main frame beam and the connecting beam are made of square steel, the connecting beam is centrally located on the side of the square frame, and the top screw is rotatably located at the center of the connecting beam.

[0008] Optionally, the auxiliary frame beam is a screw rod, which is connected to the main frame beam and locked with a nut.

[0009] Compared with the prior art, the beneficial effects of this application are:

[0010] The present application proposes a tire-assisted removal device for boarding bridges. By restricting the tire through the main frame, the tire is subjected to more even force, making it less likely to damage the equipment. At the same time, only one person needs to operate the top screw to achieve stable gripping and smooth removal of the tire. According to tests, this device reduces the time for a single maintenance operation by 60%, reduces labor costs by 75%, and effectively avoids equipment wear that may be caused by traditional operations.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0017] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0018] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0019] See attached document Figures 1 to 3 This application provides a boarding bridge tire auxiliary removal device, including a main frame for holding the boarding bridge tire 5 in place and a top screw 4 disposed on the main frame and coaxial with the central shaft 6 of the boarding bridge tire 5. The top screw 4 contacts the central shaft 6 of the boarding bridge tire 5, and the boarding bridge tire 5 is pulled out by the traction of the top screw 4 through rotation.

[0020] Specifically:

[0021] like Figures 1 to 3As shown, the main frame includes main frame beam 1, auxiliary frame beam 2, and connecting beam 3. Both main frame beam 1 and connecting beam 3 are square steel. There are four main frame beams and one connecting beam 3. The four square steel beams of the main frame beam 1 are arranged in pairs and are respectively set on the left and right sides of the boarding bridge tire 5. The connecting beam 3 is welded between the two main frame beams 1 on the same side. The auxiliary frame beam 2 consists of four screw rods. Threaded holes are provided at both ends of the main frame beam 1. The main frame beam 1 and the auxiliary frame beam 2 are threadedly connected and locked by nuts.

[0022] Meanwhile, a threaded hole is provided at the center of the connecting beam 3, and the top screw 4 is threadedly connected to the center of the connecting beam 3.

[0023] Based on the above, the present application provides an auxiliary device for removing a boarding bridge tire 5, the method of which is as follows:

[0024] First, remove the main frame beam 1 on the side where the connecting beam 3 is located from the auxiliary frame beam 2, and then place the main frame beam 1 on the opposite side of the boarding bridge tire 5.

[0025] Then, the main frame beam 1 on the side where the connecting beam 3 is located is reinstalled so that the main frame clamps the boarding bridge tire 5.

[0026] Next, use a vise to rotate the top screw 4 so that it moves closer to the central axle 6 of the boarding bridge tire 5 and abuts against the end cap of the central axle 6. Then, remove the bolts of the boarding bridge tire 5 and continue to rotate the top screw 4. Using the pulling force generated by the top screw 4, pull the boarding bridge tire 5 outward from the central axle 6 of the boarding bridge tire 5, thereby removing the boarding bridge tire 5.

[0027] It can be seen that the boarding bridge tire auxiliary disassembly device provided in this application forms a stable contact surface between the main frame and the wheel, making the tire more evenly stressed and less likely to damage the equipment. At the same time, only one person needs to operate the top screw to achieve stable gripping and smooth disassembly of the tire. According to the test, this device reduces the time of a single maintenance operation by 60%, reduces labor costs by 75%, and effectively avoids the equipment wear that may be caused by traditional operations.

[0028] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
