Detailed Description
The invention will be described in further detail with reference to the drawings and the detailed description.
Referring to fig. 1 to 4, there is provided a position monitoring apparatus of a switch cabinet grounding handcart, which includes a switch cabinet 100, a grounding handcart 200 and a pulley guide 500 disposed in the switch cabinet 100.
A front push pulley 300 is provided at a front end of the ground engaging carriage 200 on the pulley rail 500, and a rear push pulley 400 is provided at a rear end of the ground engaging carriage 200 on the pulley rail 500; a front pressing bar 800 is hinged on the pulley guide rail 500 below the front pushing pulley 300, and a front reset spring 1000 is arranged between one end of the front pressing bar 800 and the pulley guide rail 500; a state travel switch 600 for monitoring whether the grounding handcart 200 is in the switch cabin 100 is arranged at the front end of the pulley guide rail 500 below the front pressing bar 800; a rear pressing bar 900 is hinged on one side of the pulley guide rail 500, which is arranged on the front pressing bar 800, and a rear reset spring 1100 is arranged between one end of the rear pressing bar 900 and the pulley guide rail 500; a position travel switch 700 for monitoring the operating position of the grounding handcart 200 is provided below the rear bead 900 at the rear end of the pulley rail 500.
The front push pulley 300, the rear push pulley 400, the pulley guide rail 500, the front batten 800 and the rear batten 900 have no mechanical action association with other trolleys of the switch cabinet 100, and only the grounding trolleys 200 have mechanical action association when in the switch cabinet 100; the state travel switch 600 and the position travel switch 700 are only operated by the linkage action of the front pushing pulley 300, the rear pushing pulley 400, the pulley guide rail 500, the front pressing bar 800 and the rear pressing bar 900 of the grounding handcart 200, so that the position monitoring of the grounding handcart 200 is not influenced by other carts with the switch cabinet 100.
The invention relates to a position monitoring device of a switch cabinet grounding handcart, which has the following working principle:
referring to fig. 1, when the grounding handcart 200 is pushed in from the outside of the switch cabinet 100, the front pushing pulley 300 mounted on the grounding handcart 200 rotates the front end of the front pressing bar 800 on the pulley guide rail 500 downward around the hinge to push the rear end of the front pressing bar 800, the state travel switch 600 is linked by the downward pressure of the rear end of the front pressing bar 800, and the state travel switch 600 contacts act to monitor the signal that the grounding handcart 200 is in the switch cabinet 100;
when the grounding handcart 200 is in the switch cabin 100, the grounding handcart 200 is at a working position, a test position or other positions in the switch cabin 100, signals of the grounding handcart 200 in the switch cabin 100 are always transmitted by the front pushing pulley 300 arranged on the grounding handcart 200 to push the front end of the front pressing bar 800 on the pulley guide rail 500 downwards around the hinge, the state travel switch 600 is kept under the linkage of the lower pressure of the rear end of the front pressing bar 800, the contact of the state travel switch 600 is enabled to act, the signals of the grounding handcart 200 in the switch cabin 100 are monitored to be unchanged, and the reliability of the signals output by the state travel switch 600 is ensured.
Referring to fig. 2, when the grounding handcart 200 is pushed in from outside to inside of the switch house 100 and then pushed in to the working position, the rear pushing pulley 400 mounted on the grounding handcart 200 keeps the front pressing bar 800 on the pulley guide rail 500 pressed downward by the relay front pushing pulley 300, so that the state travel switch 600 is pressed without being pressed upward by the upward elastic force of the front return spring 1000, and the contact action monitoring signal of the state travel switch 600 is lost; meanwhile, the front pushing pulley 300 installed on the grounding handcart 200 rotates the front end of the rear pressing bar 900 on the pulley guide rail 500 downwards around the hinge to push the rear end of the rear pressing bar 900, the position travel switch 700 is linked by the lower pressure of the rear end of the rear pressing bar 900, and the contact point of the position travel switch 700 acts to monitor the working position signal of the grounding handcart 200. On the contrary, when the grounding handcart 200 is withdrawn to the initial position, the rear reset spring 1100 is out of pressure to prop up the rear end of the rear pressing bar 900, so that the front end of the rear pressing bar 900 rotates upwards around the hinge to restore the rear pressing bar 900 to the initial state, and the position travel switch 700 is restored to monitor the test position signal of the grounding handcart 200.
Referring to fig. 3, when the grounding handcart 200 completely exits from the switch cabinet 100, the front return spring 1000 and the rear return spring 1100 are both decompressed to respectively prop up the rear end of the front pressing bar 800 and the rear end of the rear pressing bar 900, and the state travel switch 600 and the position travel switch 700 are all restored to the initial state, so that the position signal that the grounding handcart 200 is not in the switch cabinet is monitored.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents.
