Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary tools, and particularly relates to a pressing device for a coupler air duct connector. Background Art

[0002] The coupler is installed at both ends of a locomotive, a motor car or a carriage, and is used to connect adjacent vehicles to ensure that they can be firmly coupled together during operation and can transmit traction force, braking force and absorb shocks and vibrations during operation. The air duct connector is a gas circuit connecting component located at the end face of the coupler and is used to dock the air circuits between two different trains.

[0003] As an important component for connecting trains to each other, the air duct connector of the coupler enables the high-pressure air of different trains to be used mutually. In order to ensure the coupling and uncoupling efficiency of the existing fully automatic couplers of subway trains, the air duct openings are in an exposed state. This situation causes dust to accumulate inside the air duct openings during the long-term operation of the train. When the trains are coupled, this accumulated dust will be blown into the solenoid valve at the rear end of the air duct, and in severe cases, it will cause the solenoid valve to malfunction and delay the rescue coupling on the main line.

[0004] The original method for cleaning the air duct connector was to wipe the end face of the air duct with a wiping paper and then vacuum the end face of the air duct with a vacuum cleaner. This method is difficult to effectively clean foreign matters such as sludge mixtures remaining in the long and narrow air duct. When the foreign matters enter the valve parts in the train pipeline with the high-pressure air, it has a great impact on the safe operation of the train. Moreover, the original cleaning operation did not verify the reset function of the air duct connector. Content of the Utility Model

[0005] The utility model aims to solve at least to some extent the above technical problems. For this reason, the purpose of the utility model is to provide a pressing device for a coupler air duct connector.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A pressing device for a coupler air duct connector includes a main rod. A first rotating shaft is provided at one end of the main rod. A trigger tube is rotatably installed on the first rotating shaft. Sliders are provided on opposite sides of the trigger tube. A positioning ring is arranged around the trigger tube. Two chutes are oppositely opened on the positioning ring. The sliders are slidably installed in the chutes. A second rotating shaft parallel to the first rotating shaft is also provided on the main rod. A fulcrum slot is rotatably installed on the second rotating shaft.

[0008] Preferably, a limiting plate for preventing the slider from disengaging from the chute is provided at the outer end of the slider, and the width of the limiting plate is greater than the width of the chute.

[0009] Preferably, the first rotating shaft is installed on a first U-shaped structure, and the second rotating shaft is installed on a second U-shaped structure. Both the first U-shaped structure and the second U-shaped structure are fixedly installed on the main rod.

[0010] The beneficial effects of the present utility model are as follows:

[0011] A pressing device for a coupler air duct connector provided by the present utility model can engage the fulcrum card slot with the edge of the lower end face of the coupler. Using the lever principle, the coupler's own structure is used as the fulcrum, and the action of squeezing the air duct connector when the couplers are coupled is simulated, so that the trigger tube squeezes the air duct connector and discharges the high-pressure air of the train, and the high-pressure air of the train itself is used to purge the inside of the coupler air duct.

[0015] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model. Generally, the components of the embodiments of the present utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0016] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it 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 directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0017] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0018] In order to lead out the high-pressure air in the main air duct connector, it is necessary to press down the return spring in the main air duct connector to open the air duct. However, the force required to compress the return spring is relatively large, and it is difficult for the operator to open it without using special tools. Therefore, in this embodiment, a pressing device using the lever principle is used to open the valve to lead out the high-pressure air in the main air duct connector.

[0019] Specifically, asFigure 1 and Figure 2 As shown in Figure 2 , a pressing device for a coupler air duct connector according to this embodiment includes a main rod 1. A first U-shaped structure 2 is fixedly installed at one end of the main rod 1. A first rotating shaft 3 is installed on the first U-shaped structure 2. A trigger tube 4 is rotatably installed on the first rotating shaft 3. The axis of the trigger tube 4 is perpendicular to the axis of the first rotating shaft 3. Symmetrically arranged on two opposite sides of the trigger tube 4 are sliders 5. A positioning ring 6 is arranged around the trigger tube 4. The positioning ring 6 and the trigger tube 4 are concentrically arranged. Two sliding grooves 7 are oppositely formed on the positioning ring 6. The sliders 5 are slidably installed in the sliding grooves 7, and the sliders and the sliding grooves are installed in a one-to-one correspondence. The outer end of the slider 5 is provided with a limiting plate 8 for preventing the slider 5 from disengaging from the sliding groove 7. The width of the limiting plate 8 is greater than the width of the sliding groove 7.

[0020] Near the position of the first U-shaped structure 2 in the middle of the main rod 1, a second U-shaped structure 9 is fixedly installed. A second rotating shaft 10 is installed on the second U-shaped structure 9. The second rotating shaft 10 is arranged parallel to the first rotating shaft 3. A fulcrum slot 11 is rotatably installed on the second rotating shaft 10. A square groove is provided on the side surface of the fulcrum slot 11. By using the lever principle, the fulcrum slot 11 is stuck at the edge steel plate of the coupler end face as a fulcrum. The longer main rod can increase the length of the lever arm to save physical strength for the operator.

[0021] The size of the positioning ring 6 is just right to be sleeved outside the air duct connector to play a positioning and guiding role. The trigger tube 4 is the same size as the air duct valve core and can directly press the main air duct connector valve core. When the air duct connector is pressed, the high-pressure air of the train is led out to blow the inside of the air duct connector. During the intermittent period of the high-pressure air blowing, a slender brush is used to clean the inside of the air duct, so as to improve the cleaning quality of the air duct connector. In addition, this device can also check the reset situation and the airtight situation after the action of the air duct connector while cleaning the air duct.

[0022] The pressing device of this embodiment is similar to the existing under-car exhaust operation. It can utilize the high-pressure air of at least 750 kPa of the train itself, and the exhaust time is short, about 1 s / time. At the same time, the operator pulls the main rod at the end position of the device, and the operation position is far from the trigger head and will not be impacted by the air flow. The trigger head itself has a blocking effect on the high-pressure air flow to prevent larger foreign objects from being blown out and hurting people. Therefore, this device has high safety. On the other hand, in the actual operation of the train, the coupler air duct opening is opened by the collision of couplers, and the force provided by this device is much smaller than the force generated by the coupler collision, so the coupler will not be damaged.

[0023] The present invention is not limited to the above optional embodiments. Anyone can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present invention, they all fall within the protection scope of the present invention.
