Description

Technical Field

[0001] This application relates to the field of rail vehicle technology, specifically to a control fixture and a switching mechanism having the control fixture. Background Technology

[0002] Currently, high-speed trains have strict requirements for the clearance of the "opening and closing mechanism" in the closed state, and this clearance needs to be controlled during installation. Because the train is not powered or ventilated at the installation platform, the "opening and closing mechanism" cannot be closed via system control. The clearance can only be adjusted manually after closing the "opening and closing mechanism," which differs from the state of the "opening and closing mechanism" when closed via the train system. This causes a deviation in the clearance that initially met the requirements when the "opening and closing mechanism" was controlled via the train system later, necessitating readjustment.

[0003] Therefore, to meet practical needs, a control fixture capable of controlling the opening and closing mechanism is provided. Summary of the Invention

[0092] As shown in the attached diagram of the instruction manual. Figures 1-3 In the diagram, the first air chamber is A, and the second air chamber is B.

[0093] The technical solution based on the embodiments of this application mainly includes seven parts and is implemented using the following technical solutions:

[0094] Air inlet 3, after being connected to the workshop air source, provides air to the control device;

[0095] Pressure gauge 4 displays the pressure of the air source connected to air inlet 3;

[0096] The control terminal of the first throttle valve 24 is used to correspond to the first gear of the manual directional valve (20) and to control the opening speed.

[0097] The control end of the second throttle valve 26 is used to correspond to the second position of the manual directional valve (20) and to control the closing speed;

[0105] When the manual directional valve 20 is in the middle position, there is no gas output;

[0106] When the manual reversing valve 20 is turned to the second position, that is, the "opening and closing mechanism" is closed, gas is output from T2 and input into the closing cylinder of the "opening and closing mechanism", that is, the second air chamber, which drives the "opening and closing mechanism" to close.

[0107] When the manual reversing valve 20 is turned to the first position, and the "opening and closing mechanism" is in the open position, gas is output from T1 and input into the opening and closing cylinder of the "opening and closing mechanism", that is, the first air chamber, which drives the "opening and closing mechanism" to open.

[0108] The first throttle valve 24 and the second throttle valve 26 are used to control the speed.
