Description

Technical Field

[0001] The utility model relates to the field of rail transportation, in particular to a non-metallic locomotive cover for a train locomotive. Background Art

[0002] The non-metallic front cover of a train is a protective layer or shell made of non-metallic material covering the surface of the train head. During the operation of the train, due to the high speed of the train, when it collides with other objects during operation, it may cause wear or dents on the surface of the train cover, and it needs to be maintained regularly.

[0003] After searching, Chinese patent announcement number: CN218577738U discloses a non-metallic front cover for subway, including a cover body, wherein the cover body is mainly composed of a body and a frame, and the frame is mainly composed of a roof curved beam, a side wall beam, a reinforced cross beam and a reinforced longitudinal beam, and at the same time, installation through holes are opened through the intersection of the reinforced cross beam and the reinforced longitudinal beam, and at the same time, the outer surfaces of the roof curved beam and the side wall beam are respectively provided with top guide grooves and side wall guide grooves, and installation screws are fixedly installed near the installation through holes inside the body, and the installation screws are matched with limiting nuts, and the precise positioning of the body and the frame can be achieved through the set installation through holes combined with the installation screws fixedly installed inside the body and the matching limiting nuts, and no adjustment is required during the installation process, thereby greatly improving the installation efficiency and facilitating installation.

[0004] Although the above application documents can greatly improve the installation efficiency, due to the high speed of the train, it can bring about a strong airflow during the running of the train, so that stones or debris near the vehicle will splash, which is easy to collide with the surface of the locomotive. Since the train runs at a high speed, the collision may cause the surface of the train cover to be dented, and the deformation of the train cover may cause the train cover to drive the screw to shift, thereby expanding the thread groove that originally matches the screw, resulting in poor fixing effect of the screw. Therefore, a non-metallic locomotive cover for a locomotive is proposed to solve the above problems. Utility Model Content

[0032] Reference Figure 2 - Figure 4 A pneumatic chamber 46 is provided inside the connecting rod 42, and a slide plate 47 is connected to the inner wall piston of the pneumatic chamber 46. The outer wall of the slide plate 47 fits with the inner wall of the pneumatic chamber 46. One end of the slide plate 47 close to the outer surface of the connecting rod 42 is rotatably connected to a screw rod 44. The outer wall of the screw rod 44 passes through and is threadedly connected to the outer wall of the connecting rod 42. A threaded hole matching the shape of the outer wall of the screw rod 44 is provided on the inner wall of the connecting rod 42. An airbag 45 is fixedly connected to the outer wall of the connecting rod 42. The interior of the airbag 45 is connected to the interior of the pneumatic chamber 46. The initial state of the airbag 45 is a contracted state. The shape of the airbag 45 is annular. The material of the airbag 45 is rubber. The shape and material setting of the airbag 45 ensure that the airbag 45 can fit with the inner wall of the mounting hole 41.

[0033] Reference Figure 2 - Figure 4 An anti-bias component 5 is provided inside the skeleton 1, and the anti-bias component 5 includes a mounting bin 51, which is opened on the inner wall of the skeleton 1, and a push block 52 is slidably connected to the inner wall of the mounting bin 51, and a cutting angle is provided at one end of the push block 52 close to the connecting rod 42, and a clamping block 53 is slidably connected to the inner wall of the mounting bin 51, and the cross-sectional shape of the clamping block 53 is a rectangular right-angled trapezoid cut off from a triangle, and the cutting angle of the clamping block 53 is a corner close to the push block 52, and the front and rear ends of the push block 52 are fixedly connected with a control board 54, and the right end of the control board 54 is elastically connected to the inner wall of the mounting bin 51 by a spring 55, one end of the spring 55 is fixedly connected to the right end of the control board 54, and the other end of the spring 55 is fixedly connected to the inner wall of the mounting bin 51.

[0034] Reference Figure 2 - Figure 4The left end of the card block 53 is fixedly connected with a reset plate 56, and the end of the reset plate 56 away from the push block 52 is elastically connected to the inner wall of the mounting chamber 51 through a spring 2 57, one end of the spring 2 57 is fixedly connected to the end of the reset plate 56 away from the push block 52, and the other end of the spring 2 57 is fixedly connected to the inner wall of the mounting chamber 51, and a card hole 6 is opened on the inner wall of one end of the mounting seat 3 close to the card block 53, the shape and size of the card hole 6 match the card block 53, and the card hole 6 and the card block 53 are in the same plane, and the position setting of the card hole 6 ensures that the card block 53 can enter the card hole 6 after moving.

[0035] Working principle: When in use, the staff first moves the outer cover body 2 to the outside of the frame 1 during installation, and makes the mounting seat 3 be located on the outside of the corresponding frame 1. Then the staff takes out the connecting rod 42 and pushes the connecting rod 42 into the mounting hole 41 and the connecting hole 43.

[0036] When the connecting rod 42 is pushed into the mounting hole 41 and the connecting hole 43, the staff rotates the screw 44, thereby increasing the area where the screw 44 enters the interior of the connecting rod 42, so that the screw 44 pushes the slide 47, so that the gas inside the air pressure chamber 46 enters the airbag 45 under the push of the slide 47.

[0037] When the gas enters the airbag 45, the airbag 45 expands, so that the outer wall of the connecting rod 42 fits with the inner wall of the mounting hole 41 to ensure the fixing effect. At the same time, after the connecting rod 42 enters the connecting hole 43, the connecting rod 42 pushes the push block 52 through the inclined surface of the push block 52, so that the push block 52 enters the mounting bin 51, and in the process of moving, the push block 52 pushes the card block 53 through the inclined surface of the card block 53, so that the card block 53 enters the card hole 6.

[0038] At this time, the mounting base 3 and the frame 1 are further fixed to ensure that when danger occurs, the relative position of the frame 1 and the mounting base 3 is not easily changed. When the outer cover body 2 has a problem and needs to be disassembled, the staff only needs to turn the screw 44 so that the slide plate 47 slides and the internal gas of the airbag 45 is sucked into the air pressure chamber 46, and then the staff can take out the connecting rod 42.

[0039] When the connecting rod 42 is taken out, the spring 1 55 drives the control plate 54 to reset, thereby resetting the push block 52. At this time, the block 53 is not subjected to force, so the reset plate 56 is reset under the drive of the spring 2 57, thereby making the block 53 leave the clamping hole 6, so that the mounting seat 3 has no other connection with the frame 1, and the staff can easily remove the outer cover body 2.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
