the inner cavity of the middle metal cylinder 101 at the upper part of the I-shaped sliding block 104 is an air pressure cavity 108, the air pressure cavity 108 is communicated with a small air pump 122, a one-way air inlet valve 123 is arranged at an air inlet of the air pressure cavity 108, the air pressure cavity 108 is also communicated with the outside atmosphere through an air outlet pipe 124, an electromagnetic valve 125 is arranged on the air outlet pipe 124, and the electromagnetic valve 125 and the electromagnetic coil 116 are both connected with the direct current power supply.
After the solenoid valve 125 and the electromagnetic coil 116 are reconnected with the dc power supply, the electromagnetic coil 116 is electrified to generate a magnetic force which is mutually exclusive with the magnetic disk 118, and the magnetic disk 118 is forced to move rightwards, and further drives the latch rod 117 to move rightwards, so that the latch rod 117 is separated from the drum-type slider 104, the drum-type slider 104 moves downwards under the pressure of the compressed gas in the pneumatic chamber 108 after being released, and drives the push rod 106 to move downwards, and the push rod 106 moves downwards to push open the manual knife switch 129, so that the overall circuit is disconnected.
The push rod 106 is sleeved with a spring III 107, the spring III 107 is connected between the H-shaped slide block 104 and the bottom of the middle metal cylinder 101, and a stop block 109 is fixedly connected to the inner side wall of the middle metal cylinder 101 above the H-shaped slide block 104.
Because the electromagnetic valve 125 is opened after being disconnected from the dc power supply, although the aperture of the outlet pipe is small, the compressed gas in the pneumatic chamber 108 is not completely discharged immediately, but the pressure in the pneumatic chamber 108 tends to be consistent with the atmospheric pressure as time goes on, so the i-shaped sliding block 104 moves upward under the action of the spring three 107 until the h-shaped sliding block abuts against the stop block 109, and the resetting is completed.
In addition, a fixed plate 119 is fixedly connected to the inside of the outer wall 115 of the locking assembly, the locking rod 117 penetrates through the fixed plate 119 and is in sliding connection with the fixed plate, a movable plate 120 is fixedly connected to the locking rod 117 on the left side of the fixed plate 119, and a spring five 121 is further sleeved on the locking rod 117 between the fixed plate 119 and the movable plate 120.
Therefore, after the door is closed, the pressing rod 12 is inserted between the two arc-shaped reeds 18 to force the incoming line connector 15 and the outgoing line connector 16 to be separated, so that the electromagnetic valve 125 and the electromagnetic coil 116 are disconnected from the direct current power supply, at this time, the electromagnetic coil 116 is not electrified and does not generate magnetic force, and therefore the movable plate 120 carries the locking rod 117 to reset under the action of the five springs 121 to lock the i-shaped sliding block 104 again.
Particularly, the top of the middle metal cylinder 101 is provided with a top switch box 103, a switch joint 114 is arranged in the top switch box 103, a piston plate 110 is slidably connected above the air inlet in the air pressure cavity 108, the top of the piston plate 110 is fixedly connected with a door-shaped connector 112 through a connecting rod 111, the door-shaped connector 112 is positioned in the top switch box 103 and is slidably connected with the switch joint 114, a spring four 113 is sleeved outside the connecting rod 111, the spring four 113 is connected between the piston plate 110 and the top of the middle metal cylinder 101, and the switch joint 114 is connected between the small air pump 122 and the main power line 108.
Therefore, after the gas in the pneumatic chamber 108 is exhausted, the piston plate 110 will move downwards under the action of the spring 113, so that the gate connector 112 and the switch connector 114 are kept in contact, further, the small air pump 122 and the main power line 128 are kept in a connection state, and once the manual knife switch 129 is manually switched on, the small air pump 122 is powered on to deliver air into the air pressure chamber 108 (since the closing of the door is completed, the electromagnetic valve 125 is powered off and closed), so that the air pressure in the air pressure chamber 108 is gradually increased, and then the piston plate 110 compresses the spring four 113 to move upwards, the piston plate 110 moves upwards to drive the door-shaped connector 112 to move upwards through the connecting rod 111, and finally the door-shaped connector 112 is separated from the switch connector 114, the small air pump 122 is powered off and does not work, so that the air pressure in the air pressure cavity 108 is stabilized, and the complete reset of the brake pulling mechanism is completed.
Besides, a box lock 02 is arranged on the distribution box 01, a glass window 03 is arranged on a box door of the distribution box 01, a power line 07 of the distribution box 01 is located at the bottom of the distribution box 01, and the internal situation can be observed through the glass window 03 without specially opening the box door.
The specific implementation mode and principle are as follows:
after the box door is opened, the extrusion rod 12 is separated from the arc-shaped reed 18, the incoming line connector 15 and the outgoing line connector 16 are automatically connected together under the action of the second spring 20, and the electromagnetic valve 125 and the electromagnetic coil 116 are reconnected with the direct-current power supply;
after the electromagnetic valve 125 and the electromagnetic coil 116 are reconnected with the dc power supply, the electromagnetic coil 116 is electrified to generate a magnetic force mutually exclusive with the magnetic disk 118, so as to force the magnetic disk 118 to move rightwards, further drive the latch rod 117 to move rightwards, so that the latch rod 117 is separated from the drum-shaped slider 104, the drum-shaped slider 104 moves downwards under the pressure of the compressed gas in the gas pressure chamber 108 after being released, and drives the ejector rod 106 to move downwards, the ejector rod 106 moves downwards to eject the manual knife switch 129, so that the general circuit is disconnected, at this time, the circuit is powered off, electricity stealing molecules cannot steal electricity or cannot be shocked to generate danger, and a safety is added for the operation of workers).
Because the electromagnetic valve 125 is opened after being disconnected from the dc power supply, although the aperture of the outlet pipe is small, the compressed gas in the pneumatic chamber 108 is not completely discharged immediately, but the pressure in the pneumatic chamber 108 tends to be consistent with the atmospheric pressure as time goes on, so the i-shaped sliding block 104 moves upward under the action of the third spring 107 until the third spring abuts against the stopper 109, and the first-step reset is completed.
After the worker finishes the construction, or after the electricity stealing molecule leaves (because the electricity stealing molecule causes the circuit to be powered off, the worker can come forward for inspection and plays the role of warning alarm), the worker goes to the inspection and closes the box door, after the box door is closed, the boss 06 extrudes the pressing pad 05 to enable the pushing seat 11 to move inwards, further enable the extrusion rod 12 to move inwards and be inserted between the two arc-shaped reeds 18 to force the wire inlet joint 15 and the wire outlet joint 16 to be separated, and enable the electromagnetic valve 125 and the electromagnetic coil 116 to be disconnected with the direct current power supply;
at this time, the electromagnetic coil 116 is not electrified and does not generate magnetic force, so the movable plate 120 drives the locking rod 117 to reset under the action of the five springs 121, and locks the drum-shaped sliding block 104 again to complete the second-step resetting.
After the gas in the pneumatic chamber 108 is exhausted, the piston plate 110 moves down under the action of the spring four 113 to keep the door-shaped connector 112 in contact with the switch connector 114, so that the small-sized air pump 122 and the main power line 128 are kept in a closed state, therefore, when a worker closes the manual knife switch 129 in the future (manual closing can be performed after construction is completed to ensure safety), the small-sized air pump 122 is powered on to work, air is delivered into the pneumatic chamber 108 to gradually increase the pressure in the pneumatic chamber 108, the piston plate 110 compresses the spring four 113 to move upwards, the piston plate 110 moves upwards to drive the door-shaped connector 112 to move upwards through the connecting rod 111, and finally the door-shaped connector 112 is separated from the switch connector 114, the small-sized air pump 122 is not in work when power is cut off, so that the pressure in the pneumatic chamber 108 is stabilized, and complete resetting of the brake pulling mechanism is completed.
Based on the above, the power-off control box is arranged in the electrified equipment and is matched with the door of the equipment box, so that the whole equipment is automatically powered off after the door is opened, a safety protection is added, and electricity stealing is prevented; the corresponding lock catch is controlled through the power-off control box, so that the starting of the whole brake pulling mechanism is controlled, the brake pulling power-off effect is achieved, and the problem that a small electronic switch is not suitable for a high-power transmission line is solved; and the brake-pulling mechanism can automatically reset after being pulled out, and the lock catch can be automatically locked again after the box door is closed, so that the next normal use is ensured.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
