Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The embodiment of the utility model provides a slippage formula rigidity contact net breaker, as shown in fig. 1-8, it includes an anchor section and two busbar joints. And the two busbar joints are respectively positioned in stations and intervals at two sides of the opening and closing range of the flood-proof door. The anchor section is located between two busbar joints, and the anchor section covers the whole opening and closing range of the flood gate. The anchor sections are respectively and electrically communicated with the busbar joints through the bolt type electric connection structures 11.
The anchor section includes busbar 1, slippage formula suspended structure and rotation type suspended structure, busbar 1 with slippage formula suspended structure, rotation type suspended structure are connected. The bus bar 1 is suspended on the station and the interval structure through the slip-type suspension structure and the rotary type suspension structure.
The left side portion of the busbar 1 is suspended from a low-clearance interval structure by two slip-type suspension structures. The slippage type suspension structure comprises a widening plate A7, a widened busbar wire clamp A5, a suspension insulator A3 and a suspension channel steel 4, the widening plate A7 is arranged on the edge of a busbar 1, the widening plate A7 is connected with the busbar 1 through a widening plate fixing piece 6, the widening plate A7 is installed in the widened busbar wire clamp A5, the widening plate A7 is in sliding connection with the widened busbar wire clamp A5, and the widened busbar wire clamp A5 is connected with the suspension channel steel 4 through the suspension insulator A3.
The right portion of the bus bar 1 is suspended from a high-headroom station structure by a slip-type suspension structure and a rotation-type suspension structure. In order to be suitable for high headroom, the suspension channel steel 4 of the slipping type suspension structure is suspended on the suspension base 14, and the upper end of the suspension base 14 is fixed on a station structure body. The rotary type suspension structure comprises a widening plate B10, a widening busbar wire clamp B8, a suspension insulator B9 and a suspension channel steel 4, wherein the widening plate B10 is arranged on the flange of a busbar 1, the widening plate B10 is connected with the busbar 1 through a widening plate fixing piece 6, the widening plate B10 is installed in the widening busbar wire clamp B8, the upper surface of the widening plate B10 is provided with a tooth groove for stopping the flow, the tooth groove is matched with a baffle on the lower surface of the widening busbar wire clamp B8 and used for realizing the unidirectional sliding of the widening plate B10 on the widening busbar wire clamp B8 and preventing the busbar 1 from falling off integrally in the slipping process; the widened busbar wire clamp B8 is hinged with the suspension insulator B9, so that the rotation between the widened busbar wire clamp B8 and the suspension insulator B9 can be realized; the suspension insulator B9 is fixed on a suspension channel steel 4, and the suspension channel steel 4 is fixed on a station structure through a suspension base 14. The length of the widening plate B10 is longer than that of the widening plate A7, so that the rotary type hanging structure cannot slip after the bus bar 1 at the position of the slipping type hanging structure slips.
The right end of the busbar 1 is provided with a unhooking 12, the unhooking 12 is matched with a hook 13 for use, one end of a stay wire 16 is connected with the hook 13, the other end of the stay wire bypasses a pulley and is connected with a flood gate, an insulating rod 15 is arranged on the stay wire 16, and the insulating rod 15 plays a role in electrical isolation. The unhooking 12 is a semi-closed circular ring and is reliably connected with the hook 13 when the busbar 1 is horizontal; when the busbar 1 rotates for a certain angle, the hook 13 slips from the gap of the unhooking 12, so that the busbar 1 is separated from the pull wire 16, the busbar 1 is always dragged in the closing process of the flood gate, the stroke is too long, and the widening plate B10 slips from the widening busbar wire clamp B8. The rotary type suspension structure is positioned on the right side of the slipping type suspension structure and close to the right end of the bus bar 1, so that after the bus bar 1 moves rightwards under the action of the pull wire 16, the gravity center of the bus bar 1 is still positioned on the left side of the rotary type suspension structure, and the bus bar 1 can rotate smoothly.
The length of the widening plate A7 and the length of the widening plate B10 are adjustable, so that the moving distance of the anchor section during slipping is determined, the high clearance of the vehicle station end can be fully utilized, and the bus bar 1 is prevented from contacting the ground during slipping and rotating. The bolt type electric connection structure 11 is fixedly arranged at the flange of the bus bar 1 and can slide through the widened bus bar wire clamp 2, and the movement of the anchor section along the line direction is not influenced.
As shown in fig. 1 and 3, the busbar joint is of an existing structure, specifically: the bus bar 1 is installed in a bus bar clip 2, and the bus bar clip 2 is fixed to a suspension channel 4 through a suspension insulator A3. For low clearance, the suspension channel steel 4 is fixed on a structure body through bolts; for high headroom, the suspension channel 4 is fixed to the structure by a suspension base 14, forming a reliable suspension.
When the flood gate is closed, the bus bar 1 of the anchor section is dragged to move horizontally through the mechanical linkage of the pull wire 16 and the flood gate, and the widening plate A7 and the widening plate B10 move together with the bus bar 1. When the widening plate A7 moves out of the range of the widened bus bar clip A5, the bus bar 1 drops out of the clip because the bus bar 1 flange is smaller than the width of the widened bus bar clip A5; the hinged joint of the widened busbar clamp B8 and the suspension insulator B9 is taken as a rotation point, and after the busbar 1 rotates for a certain angle, the unhooking 12 and the hook 13 are automatically separated. In the period, the bolt type electric connection structure 11 is automatically separated along with the movement of the busbar 1, and finally, the mechanical and electrical disconnection of the rigid contact net at the flood gate position is realized.
The present invention has been described in detail with reference to the embodiments, but the embodiments are only exemplary embodiments of the present invention and should not be considered as limiting the scope of the present invention. The protection scope of the present invention is defined by the claims. Technical scheme, or technical staff in the field is in the utility model technical scheme's inspiration under the utility model discloses a substantial and protection scope, design similar technical scheme and reach above-mentioned technological effect, perhaps to the impartial change that application scope was made and improve etc. all should still belong to the utility model discloses a patent covers within the protection scope.
