Description

Technical Field

[0001] This utility model relates to the field of aircraft maintenance technology, specifically a gearbox parking and transfer trailer. Background Technology

[0002] During aircraft maintenance, the aircraft gearbox needs to be inspected, maintained, and repaired. However, due to the lack of storage and transportation equipment for gearboxes in existing aircraft maintenance systems, gearboxes can only be temporarily stored on old tires during maintenance, which is very inconvenient for subsequent inspections. The transportation process can also easily cause damage to the surface of the parts, reducing the efficiency and effectiveness of aircraft maintenance. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned shortcomings by providing a gearbox parking and transfer trailer, which can store and transfer gearboxes, making subsequent maintenance of aircraft gearboxes more convenient, avoiding damage to the surface of parts during the transfer process, and improving the efficiency and effectiveness of aircraft maintenance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A speed reducer parking and transfer trailer includes a trailer body, an L-shaped bracket fixed to the trailer body, and a parking plate fixed to the L-shaped bracket. The parking plate is provided with a large circular clearance window and a plurality of hanging holes are provided around the large circular clearance window. The large circular clearance window is used to avoid the shaft on the large end cover of the speed reducer. The large end cover of the speed reducer is tightened and fixed to the hanging holes by bolts and nuts.

[0006] Furthermore, the large circular clearance window is elliptical, with its major axis vertically positioned on the parking plate and its minor axis length greater than the outer diameter of the flange on the large end cover of the reducer.

[0007] Furthermore, the horizontal part of the L-shaped bracket is fixed to the trailer body, the parking plate is fixed to the vertical part of the L-shaped bracket, and diagonal braces are symmetrically arranged on the L-shaped bracket, the diagonal braces connecting the horizontal part and the vertical part of the L-shaped bracket.

[0008] Furthermore, the mounting holes are provided in four pairs, with each pair of mounting holes positioned close to both sides of the long axis of the large circular clearance window.

[0009] Furthermore, any of the hanging holes includes a large circular hole and a small circular hole that are connected, with the large circular hole positioned above the small circular hole.

[0010] Furthermore, the large circular hole on the lower side connects to the large circular clearance window.

[0011] Furthermore, the trailer body is equipped with four swivel wheels at its bottom, and the swivel wheels are equipped with caster brakes.

[0012] The beneficial effects of this utility model are:

[0013] In practical applications, operators move the trailer to the target location, hoist the reducer, and pass the shaft on the large end cover of the reducer through the large circular clearance window until the large end cover of the reducer abuts the parking plate. The reducer is then fixed to the parking plate by tightening the large end cover and the mounting holes with bolts and nuts. The reducer can be transported by towing the trailer. This invention enables the storage and transport of reducers, making subsequent maintenance of aircraft reducers more convenient and avoiding surface damage to components during transport, thus improving the efficiency and effectiveness of aircraft maintenance.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a speed reducer parking and transfer trailer includes a trailer body 1, an L-shaped bracket 2 fixed on the trailer body 1, and a parking plate 3 fixed on the L-shaped bracket 2. The parking plate 3 is provided with a large circular clearance window 31, and a plurality of hanging holes 32 are provided around the large circular clearance window 31. The large circular clearance window 31 is used to avoid the shaft on the large end cover of the speed reducer 5. The large end cover of the speed reducer 5 is tightened and fixed to the hanging holes 32 by bolts and nuts.

[0020] In use, the operator moves the trailer to the target location, hoists the reducer 5, and makes the shaft on the large end cover of the reducer 5 pass through the large circular clearance window 31 until the large end cover of the reducer 5 abuts against the parking plate 3. The reducer 5 is then fixed on the parking plate 3 by tightening the large end cover of the reducer 5 with the hanging hole 32 using bolts and nuts. The reducer 5 can be transported by towing the trailer body 1. This utility model can store and transport the reducer 5, making subsequent maintenance of the aircraft reducer more convenient, and can also avoid damage to the surface of the parts caused during transportation, thereby improving the efficiency and effectiveness of aircraft maintenance.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the large circular clearance window 31 is elliptical, with its major axis vertically set on the parking plate 3, and its minor axis length greater than the outer diameter of the flange on the large end cover of the reducer 5. In this embodiment, when the large circular clearance window 31 is elliptical, the flange and shaft on the large end cover of the reducer 5 during hoisting can more easily pass through the large circular clearance window 31.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the horizontal part of the L-shaped bracket 2 is fixed to the trailer body 1, and the parking plate 3 is fixed to the vertical part of the L-shaped bracket 2. The L-shaped bracket 2 is symmetrically provided with diagonal braces 4, which connect the horizontal part and the vertical part of the L-shaped bracket 2. In this embodiment, the diagonal braces 4 can effectively enhance the support strength of the L-shaped bracket 2.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, four hanging holes 32 are provided, and the four hanging holes 32 are arranged in pairs close to both sides of the long axis of the large circular clearance window 31. In this embodiment, the four hanging holes 32 arranged in pairs close to both sides of the long axis of the large circular clearance window 31 can make the parking and fixing force of the reducer 5 more uniform.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, any of the hanging holes 32 includes a large circular hole 321 and a small circular hole 322 that are connected. The large circular hole 321 is located above the small circular hole 322. In this embodiment, when in use, the bolt is first passed through the large circular hole 321 and moved to the small circular hole 322. Then, the bolt at the small circular hole 322 is tightened with a nut. The process of passing the bolt through and tightening it is more convenient.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the large circular hole 321 on the lower side is connected to the large circular clearance window 31. In this embodiment, when the large circular hole 321 on the lower side is connected to the large circular clearance window 31, the two bolts on the lower side are easier to pass through the large end cover of the reducer 5, and the tightening process is more convenient.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the trailer body 1 is provided with four omnidirectional wheels at the bottom, and the omnidirectional wheels are equipped with caster brakes; in this embodiment, the trailer body 1 can be fixed by the caster brakes to prevent it from sliding away during parking.

[0027] The specific embodiments described herein are merely illustrative examples of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by this utility model.
