Abstract
Description
Technical Field
[0001] This utility model relates to a tool for auxiliary exploration operations on high-speed trains, specifically a bracket for axle end cover for auxiliary exploration operations on high-speed trains. Background Technology
[0002] When the hollow axle of a high-speed train wheelset has traveled 90,000 kilometers, or when problems involving wheel and axle defects are found during routine maintenance, hollow axle flaw detection will be used to troubleshoot the faults to ensure that the hollow axle is free of defects before it can continue to carry passengers.
[0003] Currently, during the auxiliary inspection work on the high-speed trains, each train has four LKJ2000 axle end covers, distributed in cars 01 and 00. When removing the LKJ2000 axle end covers from cars 01 and 00, there is nowhere to place them, so they can only be placed directly on the ground. However, because other work is being carried out simultaneously in the maintenance depot, there is a large amount of water and metal dust on the ground, which will cause contamination to the inside of the LKJ2000 axle end covers.
[0004] The wheel axle assembly of a high-speed train is a precision component. Contamination of the LKJ2000 axle end cover by water and metal dust can cause overheating, posing a danger to the train's operational safety and passenger safety. Therefore, it is necessary to design an auxiliary axle end cover support for high-speed trains to prevent contamination by water and metal dust, thus ensuring the safety of both train operation and passenger safety. Utility Model Content
[0005] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a support bracket for the axle end cover of the EMU auxiliary exploration operation. The bracket can support the axle end cover, provide a placement position for the axle end cover, effectively avoid contamination by water and metal dust, and help ensure the safe operation of the EMU.
[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0012] The opening of the adapter is inserted from one side of the rail, causing the fixing hole to be located outside the top of the rail, and the fastener passes through the fixing hole to achieve the connection between the connecting arm and the rail.
[0013] Preferably, the fixing hole is a threaded hole; the fixing element is a bolt.
[0014] Preferably, the adapter has a through hole on its side, the connecting arm passes through the through hole, and a locking member is provided at the end of the connecting arm that passes through the through hole, the length of the locking member being greater than the diameter of the through hole.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0032] Example 1
[0033] See Figures 1-3 This embodiment discloses a support bracket for an axle end cover used in auxiliary exploration operations of a high-speed train, including a support 1, at least two connecting arms 2, and a support member 3. The support 1 has placement holes 4, which are adapted to the size of the axle end cover, primarily to the threaded portion or other smaller outer diameter parts of the axle end cover. This allows a portion of the axle end cover to be inserted into the placement holes 4, with the larger outer diameter portion of the axle end cover supported on the support 1, thus enabling the placement of the axle end cover. One end of each connecting arm 2 is connected to the support 1, and the other end of all connecting arms 2 extends to the same side. Each connecting arm 2 has a fixing component for locking and securing it to the rail at its end away from the support 1. One end of the support member 3 is connected to the support 1, and the other end can be supported on the ground. The support member 3 and each connecting arm 2 provide support for the support 1 away from the ground.
[0034] Furthermore, the fixing assembly includes an adapter 5 and a fixing member 15. The adapter 5 is U-shaped, with its opening facing the rail side. A fixing hole 6 is provided on the top surface of the adapter 5. The opening of the adapter 5 is inserted into the rail from one side, causing the fixing hole 6 to be located outside the top of the rail. The fixing member 15 passes through the fixing hole 6 to achieve the connection between the connecting arm 2 and the rail. In this embodiment, the fixing assembly utilizes the difference in width between the top and bottom of the rail, allowing the fixing hole 6 to extend beyond the top of the rail after the adapter 5 is inserted into the rail, with no obstructing parts below. Combined with the use of the fixing member 15, the entire connecting arm 2 and the rail can be locked and fixed.
[0035] In this embodiment, the fixing hole 6 is a threaded hole; the fixing member 15 is a bolt (not shown in the figure). In this way, when the fixing member 15 is inserted into the fixing hole 6, the stability of both is further improved by the threaded engagement. Moreover, the height of the fixing member 15 can be easily adjusted by the threaded engagement, making it easier to adapt and combine with the rail.
[0036] Furthermore, the adapter 5 has a through hole on its side, through which the connecting arm 2 passes. A locking member 13 is provided at the end of the connecting arm 2 that passes through the through hole, and the length of the locking member 13 is greater than the diameter of the through hole. Specifically, in this embodiment, the locking member 13 is a pin or shaft structure, which passes through the end of the connecting arm 2 and serves to lock the end of the connecting arm 2 onto the adapter 5, preventing the connecting arm 2 from detaching from the adapter 5.
[0037] In this embodiment, the end of the connecting arm 2 furthest from the fixing component is rotatably connected to the bottom surface of the support 1. To achieve the rotatable connection between the end of the connecting arm 2 and the support 1, two opposing first fixing blocks 7 are provided at the corresponding positions on the bottom surface of the support 1 and the end of each connecting arm 2. The end of the connecting arm 2 is located between the two first fixing blocks 7 and is hinged to the two first fixing blocks 7 through a first rotating shaft 8, thereby realizing the rotatability of the connecting arm 2 and completing the connection between the connecting arm 2 and the support 1. The use of the first rotating shaft 8 can further prevent the connecting arm 2 from loosening from the support 1 and improve the support stability.
[0038] Furthermore, the bottom surface of the support 1 is provided with two opposing first clamping blocks 9 at the corresponding positions of each connecting arm 2; the connecting arm 2 is located between the two first clamping blocks 9. By setting the first clamping blocks 9, the position of the connecting arm 2 is further limited, thereby further improving the stability of the connecting arm 2.
[0039] In this embodiment, the support member 3 is rotatably connected to the bottom surface of the support 1. The bottom surface of the support 1 and the end of the support member 3 are provided with two opposing second fixing blocks 10. The end of the support member 3 is located between the two second fixing blocks 10, and the end of the support member 3 and the two second fixing blocks 10 are hinged through a second rotating shaft 11.
[0040] Two opposing second clamping blocks 12 are provided on the bottom surface of the support 1 and at the corresponding position of the support member 3; the support member 3 is located between the two second clamping blocks 12. The second clamping blocks 12 are provided so that the support member 3 can remain close to the bottom surface of the support 1 when folded and stored, which is convenient for transportation and storage and reduces the space occupied.
[0041] Furthermore, the surface fabricated in this embodiment is provided with a plurality of grooves 14. Specifically, two grooves are provided in this embodiment. The grooves 14 can be used to place loose parts during the operation, such as bolts, nuts, screws, etc.
[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
