Description

Technical Field

[0001] The utility model relates to an integrated guide rail valve device. Background Art

[0002] The valve assembly is a component of removable AC metal-enclosed switchgear and control equipment. It has two switchable positions, controlling the exposure and shielding of the static contacts. A typical valve assembly consists of a trolley guide rail, a valve drive mechanism, and a cabinet mid-panel. The trolley's forward and backward movement within the rail activates the valve drive mechanism, opening and closing the cabinet mid-panel. For operator safety, the trolley must be reliably grounded when it is moved in. Existing trolley guide rails merely guide the trolley's rollers, resulting in poor integration and a lack of grounding. This improvement and optimization is being developed to address this issue. Utility Model Content

[0019] like Figure 1-7As shown, the integrated guide rail valve device involved in the utility model includes a trolley guide rail assembly 1, a valve driving mechanism 2 and a partition plate 3 in the cabinet, the trolley guide rail assembly 1 includes a guide rail lower plate 5, a guide rail upper plate 6, a main copper plate 7, a grounding copper plate 8 and a trolley contact assembly 9, the trolley contact assembly 9 includes a contact plate 11, the guide rail lower plate 5 includes a lower plate mounting portion 15 fixed to the cabinet, the end of the lower plate mounting portion 15 is bent inward 180 degrees to form a lower plate reinforcement portion 16 for the trolley roller to bear, the lower plate reinforcement portion 16 is bent vertically upward to form a lower plate docking portion 17; the guide rail upper plate 6 includes an upper plate main body 19 for positioning on the trolley roller, one end of the upper plate main body 19 is vertically bent to form an upper plate docking portion 20 that is in contact with the lower plate docking portion 17, and a copper plate limiting socket 21 is provided on the upper plate docking portion 20, and the main copper plate 7 includes a copper plate arranged parallel to the upper plate. The main copper plate contact portion 22 above the plate body 19 and the main copper plate mounting portion 23 that fits with the upper plate docking portion 20 after being inserted into the copper plate limiting socket 21, the contact plate 11 includes a contact plate arc portion 25 that contacts the trolley shell and a contact plate mounting portion 26 fixed below the main copper plate contact portion 22, and the grounding copper plate 8 is fixed to the rear of the main copper plate mounting portion 23. When the trolley is pushed in, the trolley roller rolls back and forth on the lower plate reinforcement portion 16, and the upper plate body 19 serves as the upper limit of the trolley roller. During the movement of the trolley shell, it is squeezed and contacted with the contact plate arc portion 25 of the contact plate 11, thereby realizing the conduction between the trolley shell and the main copper plate 7, and the main copper plate 7 is connected to the grounding copper plate 8. The design of the main copper plate 7, the grounding copper plate 8 and the trolley contact assembly 9 realizes the integration of guidance and grounding of the trolley guide rail, improves the operational safety, and ensures that the trolley is grounded reliably.
