The top of the smooth portion 17b is provided with a hexagonal prism-shaped rotating portion 17c.
The utility model provides an urgent cab apron structure for train, when not needing to use and collecting up the cab apron and deposit, because first handrail 2 and second handrail 3 can both rotate to laminating at the top of cab apron body 1 (when cab apron body 1 is placed horizontally, acquiesce that its top is the top, the same below), the whole cab apron is the platykurtic at this moment, convenient to shift, deposit and transport etc.; when the cab apron body 1 is used, after the cab apron body 1 is flatly placed to a proper position (such as between a fault train and an adjacent train or between the fault train and a platform), the first handrail 2 and the second handrail 3 are rotated to be in a vertical state, then the positioning pin 5 is moved, the bottom of the positioning pin 5 is inserted into the positioning hole 4, and at the moment, the first handrail 2 and the second handrail 3 can be ensured to be in a vertical state under the connecting action of the positioning pin 5; therefore, when people walk outwards from the cab apron body 1, the safety protection effect can be achieved. After the use is accomplished, only need upwards extract locating pin 5 from locating hole 4, later rotate first handrail 2 and second handrail 3 laminate to cab apron body 1 can, simple and convenient. Meanwhile, the cab apron body 1 is of a whole plate structure, so that the strength is sufficient, and the interior of the cab apron body is not required to be perforated, so that the production cost is lower, and the production difficulty is lower; meanwhile, under the condition of needing the same strength, the whole weight of the automobile is lighter, and the automobile is in line with the concept of green travel of trains, motor cars and the like.
When the handrail is needed to be used, firstly, a worker directly rotates the rotating part 17c, and directly pulls out the limiting piece 17 from the second bending part 16 after separating the thread part 17a from the first bending part 15, because although the edge of the middle part of the second handrail 3 is abutted against the inner wall of the top of the limiting buckle 13 (ensuring the position stability of the second handrail 3), a set interval is formed between the inner walls of the two sides of the limiting buckle 13 and the second handrail 3 (wherein the set interval, the set interval and similar words indicate that the two structures are not in a contact state, and the specific size can be adjusted and selected according to actual conditions);
meanwhile, the edge of the middle portion of the first handrail 2 abuts against the lower side of the limiting member 17 located between the first bent portion 15 and the second bent portion 16 (the position stability of the first handrail 2 is ensured), and a set distance is provided between the motion track of the first handrail 2 and the first bent portion 15 and the second bent portion 16 (i.e. the interaction between the first handrail 2 and the first bent portion 15 and the second bent portion 16 can be avoided when the first handrail 2 is rotated);
so that the first handrail 2 can now be turned directly upwards; during the rotation of the first handrail 2, the operation part 7 is attracted by the magnetism of the anti-falling part 8, so that the positioning pin 5 can not influence the rotation of the first handrail 2; meanwhile, the first handrail 2 drives the two connecting cylinders 10 at the two ends to rotate on the supporting piece 9, and the positioning bulges 11 also rotate along with the connecting cylinders 10; until the positioning projection 11 abuts against the inner wall of the fitting groove 12, the first handrail 2 is rotated to a vertical state; the workman only needs downward separation operation portion 7 and anticreep portion 8 after, inserts the bottom of locating pin 5 in locating hole 4, can accomplish the location to first handrail 2, and is simple and convenient.
When the second handrail 3 is rotated, the second handrail 3 only needs to be directly rotated outwards, and after the second handrail 3 is in a vertical state, the positioning pin 5 on the second handrail 3 is moved downwards and inserted into the positioning hole 4. Although the operating part 7 and the anti-falling part 8 have certain magnetism, the magnetic attraction force between the operating part 7 and the anti-falling part 8 is small, and the anti-falling part 8 cannot lift the height of the positioning pin 5 in the using process.
The connecting cylinder 10 is long cylindrical, so that the movement stability of the first handrail 2 and the second handrail 3 can be improved; meanwhile, the positioning protrusions 11 are abutted against the inner wall of the fitting groove 12, so that a worker mainly applies an outward force when using the first handrail 2 and the second handrail 3; when the acting force is applied outwards, the acting force of the first handrail 2 and the second handrail 3 can be better and directly transmitted to the cab apron body 1 through the elongated positioning protrusions 11, so that the bearing capacity and the service life of the first handrail 2 and the second handrail 3 are improved.
When the second handrail 3 is in use, the limiting piece 17 can be used or not used; after use, the height of the positioning pin 5 on the second handrail 3 is first raised by the operating part 7 until the operating part 7 is attached to the anti-drop part 8, and then the second handrail 3 is rotated downward and the second handrail 3 is attached to the apron body 1. The anti-drop part 8 can prevent the operation part 7 and the positioning pin 5 from being separated from the first handrail 2 and the second handrail 3, and can be directly used when being used next time. After the first handrail 2 is also rotated to be attached to the cab apron body 1 in the same way, the limiting piece 17 penetrates through the hole in the second bent part 16 and then is in threaded connection with the first bent part 15 until the top of the smooth part 17b finally abuts against the first handrail 2, so that the first handrail 2 and the second handrail 3 are positioned simply and conveniently.
Because the limiting part 17 is in an inclined state, in actual operation, a larger operation space can be arranged above the limiting part 17, and the operation is more convenient and faster. Meanwhile, the rotating part 17c is hexagonal prism-shaped, so that the operation can be performed manually without using a tool in the actual operation, and the use convenience is higher. Furthermore, since the smooth portion 17b has a diameter larger than that of the screw portion 17a and has a smooth outer wall, it is possible to easily and conveniently separate and couple the stopper 17 and the second handrail 3.
It should be noted that, in the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
