Description

High-speed EMU water injection port and sewage outlet inspection door

technical field

The utility model relates to a manual door structure for a water injection port and a sewage discharge port of a high-speed EMU, which belongs to the technical field of rail vehicle manufacturing. the

Background technique

For railway passenger cars including EMUs, water tanks and dirt tanks are installed in the equipment compartment at the bottom of the car body, and correspondingly, water injection ports connected to the water tanks and dirt tanks are provided on the skirts on both sides of the car body. The sewage outlet connected to the sewage tank is used to fill the water tank in the train and discharge sewage to the sewage tank at the railway platform or the bullet train base. the

At present, the inspection doors of the water injection port and the sewage discharge port commonly used are relatively simple, including a door panel, which adopts a common folding door structure, and is fastened by four-corner locks or triangular locks. When operating, it is necessary to unlock the lock first, then open the hinged door, and then lock the lock after the operation is completed. The operation of this hinged door structure is time-consuming (there is a strict time requirement when operating on the platform), and the lock is prone to failure after long-term operation. When the vehicle is running, under the action of wind pressure, the inspection door will automatically open, and protrude out of the vehicle body, beyond the vehicle limit, and collide with objects outside the vehicle, which has a very large unsafe factor. the

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As shown in Figure 1, the high-speed EMU water injection port and the sewage outlet inspection door described in the utility model are opened on the skirt plates 13 on both sides of the car body, and the inspection doors of the water injection port and the sewage outlet have the same structure. The sewage outlet is located on the inner side of the inspection door, and the operation of water injection and sewage discharge can be performed by opening the inspection door. the

As shown in FIG. 1 , the inspection door includes a door panel 1 and a door panel frame 2 , and the door panel frame 2 is fixed on the inner wall of an apron 13 by screws 3 . As shown in FIG. 2 , slideways 4 are provided on both sides of the door frame 2 , and the openings of the slideways 4 on both sides are opposite. As shown in Figure 3, brackets 5 are fixed on both sides of the door panel 1, and a sliding assembly is provided on each bracket 5, the sliding assembly includes a bearing 6 fixed on the bracket 5 and a roller 7 installed in the bearing 6, The roller 7 slides along the slideway 4 to realize the opening and closing of the door panel 1 . the

As shown in Figure 2, in this embodiment, the slideway 4 located on one side of the door panel frame 2 is divided into upper and lower sections, which are respectively an upper slideway 4a and a lower slideway 4b, and there are 4 slideways in total. The top and bottom of one side are correspondingly fixed with two upper and lower brackets 5 and two sets of bearings 6 and rollers 7. The rollers 7 arranged on the top of both sides of the door panel 1 slide in the upper slideways 4a on both sides, and are arranged on The rollers 7 at the bottom of both sides of the door panel 1 slide in the glide paths 4b on both sides. the

The upper slideway 4a is roughly in the shape of an "L" extending toward the inside of the vehicle body. The bend is a circular arc transition, and the slideway 4b extends vertically. 1. When opening, it can reasonably avoid the equipment under the vehicle and meet the space requirements of the apron 13 and the inner side of the inspection door. The glideway 4b is used to limit the movement track of the bottom of the door panel 1. When the door panel 1 is opened, the bottom of the door panel 1 moves upwards, and the top of the door panel 1 moves toward the inside of the vehicle body until the door panel 1 is fully opened. Door panel 1 moves toward the inboard direction of the car body under the restriction of slideway 4, also can not protrude outside the car, and causes safety accident, meanwhile, door panel 1 is opened to the inside and also does not affect water injection and sewage discharge operation. the

A group of spring stoppers 8 are respectively embedded in the top and bottom of the glideway 4b, and a group of spring stoppers 8 are embedded in the bottom of the upper slideway 4a. The spring stops 8 at the bottom of the slideway 4b and the bottom of the upper slideway 4a are used to limit the closed state of the door panel 1. When the door panel 1 is closed, the rollers 7 on both sides of the door panel 1 are stopped by two sets of spring stops 8, so that the door panel 1. It is always closed during the operation of the vehicle, and will not be opened due to the vibration generated by the operation of the vehicle, resulting in noise. the

A set of spring stops 8 at the top of the glideway 4b are used to limit the opening state of the door panel 1. When the door panel 1 is opened, the rollers 7 at the bottom of the door panel 1 are stopped by the spring stoppers 8, so that the door panel 1 stops at the opened position. state, so that the operator can perform water injection and sewage discharge operations. When the door panel 1 is opened or closed, the operator only needs to apply a little force to overcome the elastic force of the spring stopper 8 . the

A dust-proof cover 9 is set at each spring stop 8, and the dust-proof cover 9 is fixed on the door panel frame 2 by screws, which not only plays a dust-proof role, but also facilitates disassembly to adjust the stop position of the spring stop 8 , to ensure that under the action of an appropriate force, it is convenient to perform opening and closing operations, and to maintain the door panel 1 in an open or closed state. the

There is an inwardly concave flange 10 around the door panel 1, and a rubber sealing strip 11 is arranged on the outer surface of the flange 10. When the door panel 1 is closed, the outer surface of the door panel 1 is flush with the outer surface of the apron 13. , to ensure the overall aesthetics of the car body, at the same time, the rubber sealing strip 11 seals the gap between the door panel 1 and the skirt 13 to meet the sealing requirements and prevent water and dust from entering the skirt 13 inside. the

As shown in Figure 1, be provided with at least one handle 12 on the outer surface of door panel 1, the number and the position of handle 12 are determined according to the equipment installation situation at the bottom of the car body, to avoid the equipment under the car. the

The door panel 1 , the door panel frame 2 and the slideway 4 are all made of aluminum profiles to ensure flatness and manufacturing tolerances, so as to ensure that the door panel 1 can slide smoothly and unimpeded in the slideway 4 . At the same time, the use of aluminum profiles can also ensure the overall strength of the inspection door and reduce the weight of the inspection door to meet the requirements of lightweight vehicles. the

As shown in Figure 1 and Figure 3, a connecting rod 14 is connected between the two upper slideways 4a on both sides of the door body frame 2 and between the two slideway 4b to enhance the overall strength of the slideway 4. effect. the

The inspection door adopts a slideway structure, which has the advantages of easy installation, convenient opening and closing, quick operation, safe operation, beautiful appearance and no need to add locks for closing. the

As mentioned above, a similar technical solution can be derived in combination with the content of the solution given in the accompanying drawings. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model without departing from the content of the technical solution of the utility model still belong to the scope of the technical solution of the utility model. the
