Abstract
The utility model relates to a press-clamping type rollback mechanism, which belongs to a matching device of a current collector on a subway and a light rail, and comprises a connecting plate, a saddle pad, an outer hexagon bolt, a rollback fixing plate, a rollback plate, an inner hexagon countersunk screw, a pull rod, a screw sleeve, a pressure spring and an ejector rod, wherein the rollback fixing plate is fixed on the connecting plate by the saddle pad and the outer hexagon bolt, and the connecting plate is used for being connected with a current collecting supporting arm of the current collector; the pull rod penetrates through the screw sleeve and is sleeved into the pressure spring to be in threaded connection with the ejector rod, the screw sleeve is in threaded connection with the backspacing plate, and the hexagon socket countersunk head screw is used for installing the backspacing plate on a current collection arm of the current collector. The utility model has the advantages that: novel structure presses the card formula to take off boots, and the drawing type resets, labour saving and time saving, and convenient operation can realize taking off boots operation at train door position, use hand tool to the current collector, does not need train personnel to go to operate under the car, and is safe convenient.
Description
Technical Field
The utility model belongs to the supporting device of the current collector on subway and the light rail is applied to on the current collector of subway or light rail train, provides the device of taking off boots, locking for the current collector.
Background
The urbanization process impels the city to constantly expand, and the requirement to the traffic is higher and higher, and the mode of transportation of convenient and fast trip is more and more received people's welcome, and subway and light rail play important role in the city, and many major-school cities are all building the subway, and the current collector is the device that receives the current that must lack, and the device that backs that the current collector used uses mostly uses the design of backing control lever with backing arm, has that the structure is more complicated, take off the boots hard, the easy wearing and tearing and occupation space are big problem.
Disclosure of Invention
The utility model provides a press-clamping type rollback mechanism to solve the problems that the existing rollback device is complex in structure, hard to remove boots, easy to wear and large in occupied space.
The utility model discloses the technical scheme who takes: the device comprises a connecting plate, a saddle pad, an outer hexagon bolt, a backspacing fixed plate, a backspacing plate, an inner hexagon countersunk head screw, a pull rod, a screw sleeve, a pressure spring and a push rod, wherein the backspacing fixed plate is fixed on the connecting plate by the saddle pad and the outer hexagon bolt, and the connecting plate is used for being connected with a current collection supporting arm of a current collector; the pull rod penetrates through the screw sleeve and is sleeved into the pressure spring to be in threaded connection with the ejector rod, the screw sleeve is in threaded connection with the backspacing plate, and the hexagon socket countersunk head screw is used for installing the backspacing plate on a current collection arm of the current collector.
The retraction fixing plate is provided with an inclined plane.
The top of the ejector rod is provided with an inclined plane.
The utility model has the advantages that: novel structure presses the card formula to take off boots, and the drawing type resets, labour saving and time saving, and convenient operation can realize taking off boots operation at train door position, use hand tool to the current collector, does not need train personnel to go to operate under the car, and is safe convenient.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is an exploded view of the present invention;
fig. 3 is a schematic diagram of the present invention matched with a current collector.
Detailed Description
The device comprises a connecting plate 1, a saddle pad 2, an outer hexagon bolt 3, a backspacing fixed plate 4, a backspacing plate 5, an inner hexagon countersunk head screw 6, a pull rod 7, a screw sleeve 8, a pressure spring 9 and a push rod 10, wherein the backspacing fixed plate 4 is fixed on the connecting plate 1 by the saddle pad 2 and the outer hexagon bolt 3, and the connecting plate 1 is used for being connected with a current collection supporting arm of a current collector; the pull rod 7 penetrates through a screw sleeve 8 and is sleeved in a pressure spring 9 and then is in threaded connection with a top rod 10, the screw sleeve 8 is in threaded connection with the backspacing plate 5, and an inner hexagonal countersunk head screw 6 is used for installing the backspacing plate 5 on a current collecting arm of the current collector;
the retraction fixing plate 4 is provided with an inclined surface;
the top of the ejector rod 10 is provided with an inclined surface.
The working principle is as follows:
connecting the connecting plate 1 with a current collection supporting arm of a current collector, and installing a return plate 5 on the current collection arm of the current collector; when a defective current collector is separated from the third rail, only the current collecting arm of the current collector needs to be pushed downwards, the current collecting arm drives the retraction plate 5 arranged on the current collecting supporting arm to rotate upwards, when the current collecting arm rotates to a certain angle, the ejector rod 10 is locked by the inclined surface of the retraction fixing plate 4 under the action of the pressure spring, and meanwhile, the current collecting arm is locked at a certain height to meet the requirement of separating from the third rail;
when the current-receiving arm is required to be in a boot lifting state and to be in contact with the third rail again for taking current, the tail end of the pull rod 7 is pulled, the ejector rod 10 is separated from the inclined surface of the retraction fixing plate 4, and the current-receiving arm position meets the requirements of a working state and the current-receiving of the carbon sliding plate.
