Description

Technical Field

[0001] This utility model relates to railcar technology, and more specifically, to an electric emergency brake valve device for railcars. Background Technology

[0002] To ensure operational safety when railcars propel flatcars, open wagons, and other vehicles, the current method involves a guide crouching at the front of the flatcar or holding a signal flag under the car to guide it. Simultaneously, the guide pulls a rope connected to a simple brake valve to control the brake valve. The current manual simple brake valve is a simple valve installed at the brake hose interface. This valve controls the brake hose to release air and reduce pressure to the atmosphere. The operation involves manually pulling a rope connected to the valve. Pulling the rope opens the valve, releasing air and braking. Releasing the rope closes the valve.

[0003] However, during the propulsion operation, problems such as unresponsive hand-operated brake valves, brake hoses swinging with the ropes, and inconvenience for guides resulted in poor braking performance. Furthermore, there was a safety risk of falling from the front of the flatcar when personnel were crouching on it to pull the brake valve; and a risk of being scraped by the vehicle when personnel were pulling the brake valve from below.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0021] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0022] It should be noted that in the description of this utility model, the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] Furthermore, in this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Moreover, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0025] like Figure 1 The electric emergency brake valve device for a railcar shown includes: a railcar brake hose assembly 1, a brake valve 2, wherein the brake valve 2 is mounted at the air outlet of the railcar brake hose assembly 1 via a mounting bracket 3, and is characterized in that it further includes: a remote control relay 4 electrically connected to the brake valve 2, and a remote control 5 communicatively connected to the remote control relay 4.

[0026] The brake valve 2 is configured as a solenoid valve.

[0027] Working principle:

[0028] During operation, the railcar needs to brake and stop if there are personnel or equipment on the track. The operator presses remote control 5, and remote control relay 4 receives the signal from remote control 5. Remote control relay 4 then energizes and opens the solenoid valve, causing the railcar's brake hose assembly 1 to release air and brake to a stop. When the track returns to normal, pressing remote control 5 closes the solenoid valve, releasing the brake, and the vehicle resumes normal operation. By configuring brake valve 2 as a solenoid valve, the problem of operators having to pull the valve with a rope within a 2-meter range is solved through remote control. The improved solenoid valve can be operated from anywhere on the railcar, and the valve opens more promptly; pressing remote control 5 opens the valve for braking, eliminating the buffer time from pulling the rope to valve opening. This is of great significance for the safe operation of the railcar.

[0029] In the above technical solution, the mounting bracket 3 includes: a base plate 6, one side of which has two bent portions 7 of different lengths, the end of the longer bent portion 7 has an arc-shaped limiting portion 11, and a connecting hole 13 is provided in the middle of the longer bent portion 7. The air outlet 101 of the railcar brake hose assembly 1 is connected to the internal channel of the solenoid valve through the connecting hole 13.

[0030] The railcar brake hose assembly 1 is provided with a limiting member I8 and a limiting member II9 that cooperate with two bent portions 7. The longer bent portion 7 abuts against the inner side wall of the limiting member I8, and the shorter bent portion 7 abuts against the outer side wall of the limiting member II9.

[0031] In this design, a sealing ring is provided on the contact surface between the railcar brake hose assembly 1 and the longer bend 7, and a groove 10 with the same shape as the limiting part 11 is provided on the limiting member I 8. Using this technical solution, the solenoid valve is first installed at the connection hole 13 of the longer bend 7 on the base plate 6 and connected to the railcar brake hose assembly 1, so that the solenoid valve communicates with the railcar brake hose assembly 1. The mounting bracket 3 rotates around the connection hole 13. When the longer bend 7 contacts the inner wall of the limiting member I 8, the longer bend 7 is bent towards the shorter bend 7, compressing the sealing ring. The mounting bracket 3 is then further rotated so that the shorter bend 7 abuts against the outer wall of the limiting member II 9. When the mounting bracket 3 is loosened, the sealing ring applies pressure to the contact surface of the longer bent portion 7 of the mounting bracket 3, so that the bent portion 7 fits tightly with the surfaces of the limiting member I 8 and the limiting member II 9. At the same time, the groove 10, being an arc-shaped limiting portion 11, plays a certain guiding role during rotation.

[0032] In the above technical solution, the limiting part 11 has two arcs of different sizes;

[0033] In this design, the arc dimension below the limiting part 11 matches the dimension of the groove 10, while the arc dimension above the limiting part 11 is larger than the dimension of the groove 10. Using this technical solution, once the lower arc of the limiting part 11 is fully inserted into the groove 10, continued rotation of the mounting bracket 3 ensures a stable connection between the larger lower arc of the limiting part 11 and the limiting member Ⅰ8.

[0034] In the above technical solution, a handle 12 is provided on the other side of the base plate 6. With this technical solution, the operator holds the handle 12 and rotates it around the connecting hole 13. With the cooperation of the groove 10 on the limiting part 11 and the limiting member I8, the installation bracket 3 can be completed with one hand.

[0035] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
