specific Embodiment approach 1

[0019] Specific implementation mode one: as Figures 1 to 4 As shown, an opening and closing mechanism based on the principle of the slider crank mechanism, the opening and closing mechanism includes a power source push cylinder 4, a crank sliding mechanism and a connecting mechanism connected with the front fairing, the crank sliding mechanism includes a crank connecting rod 3 and a sliding mechanism, one end of the crank connecting rod 3 is fixedly connected to the fixed part of the sliding mechanism, the other end is hinged to the connecting mechanism, the sliding part of the sliding mechanism is hinged to the connecting mechanism; one end of the power source pushing cylinder 4 is fixed on the fixed part of the sliding mechanism, The other end is connected with the sliding part of the sliding mechanism. When the power source pushes the cylinder to push the sliding part of the sliding mechanism to move, the connecting mechanism hinged on the sliding part of the sliding mechan...

specific Embodiment approach 2

[0027] Specific embodiment two: different from specific embodiment one, in specific embodiment two, the sliding part of the sliding mechanism and the power source pushing cylinder 4 are all provided with two, each sliding part is all hinged a fairing connecting arm 6, And push cylinder 4 to be connected with a power source, both sides hatch door of front fairing hatch door can be made to open or close simultaneously, also can make front fairing hatch hatch one side hatch open or close independently.

[0028] Working principle: (1) The hatches on both sides of the front fairing hatch are opened or closed at the same time

[0029] When the front fairing is opened, the two power sources push the cylinder 4 and pull the sliding frame 5 to retreat at the same time. At this time, the two fairing connecting arms 6 realize retreating under the action of the crank connecting rod 3 and the sliding frame 5, and rotate simultaneously, thereby Rotate to a suitable space, and open the hatch...

Abstract

The invention relates to a slider-crank mechanism principle-based opening and closing mechanism, which comprises a power source pushing cylinder, a crank sliding mechanism and a connecting mechanism connected with a front end fairing, wherein the crank sliding mechanism comprises a crank connecting rod and a sliding mechanism; one end of the crank connecting rod is fixedly connected to a fixed part of the sliding mechanism, and the other end of the crank connecting rod is hinged with the connecting mechanism; a sliding part of the sliding mechanism is hinged with the connecting mechanism; one end of the power source pushing cylinder is fixedly arranged on the fixed part of the sliding mechanism, and the other end of the power source pushing cylinder is connected with the sliding part of the sliding mechanism; and when the sliding part of the sliding mechanism is pushed to move by the power source pushing cylinder, the connecting mechanism hinged with the sliding part of the sliding mechanism rotates during translational motion. According to the slider-crank mechanism principle-based opening and closing mechanism, simultaneous motion of rotation and translation is realized by using one power source, so that a fairing cabin door is opened and closed through one action in a narrow front end space of a high speed train; and the slider-crank mechanism principle-based opening and closing mechanism has the advantages of low cost, high stability and convenience in overhauling.

Description

technical field [0001] The invention relates to the technical field of railway vehicle machinery manufacturing, in particular to an opening and closing mechanism at the front end of a high-speed EMU. Background technique [0002] In order to realize the reconnection or return rescue on the train of the high-speed EMU, front-end opening and closing mechanisms are usually installed at both ends of the train set head. The front-end opening and closing mechanism is an important part of the EMU. During the normal operation of the EMU (that is, in the non-reconnected state), the opening and closing mechanism is in the closed state. At this time, the front fairing hatch is closed, so that the high-speed EMU has a good The aerodynamic shape prevents the entry of blades, dust, ice and snow, and protects the couplers and other facilities inside the front fairing; the opening and closing mechanism can be opened automatically or manually in the case of return or rescue, thereby opening ...
