The problem of security risks that exist at the time of the machine.

To sum up, compared with the prior art, the present invention provides a smart management device for switch machine hand tools, which has a scientific structural design and can be used as a daily storage box for switch machine hand tools, which is convenient to take and use. It is clear at a glance whether the crank handle is missing, which is convenient for management; it can solve the problem in the prior art that cannot be dealt with in an emergency due to the lack of the hand crank tool (ie hand crank handle) of the switch machine, which is not found in time, and has great practical significance in production.

In addition, the device of the present invention has the ability to identify and prevent cheating. The device is provided with an identification sleeve with a specific mouth, and only hand tools (ie, hand cranks) with matching teeth are allowed to pass through the identification hole (ie, the inner hole of the identification sleeve). ), so that it can really play a role in intelligent management of the hand tools of the switch machine, and avoid the wrong insertion of the hand tools that do not match the switch machine.

In addition, in specific applications, by using the device of the present invention in parallel with other warning devices (such as warning lights, alarm bells, etc.), when the hand crank in the device of the present invention is not taken out, the dynamic and static contact groups are in the connected state. It is equivalent to a wire, and the warning device connected in parallel with it is in a short-circuit state and does not work; when the hand crank is taken out, the dynamic and static contact groups are in a disconnected state, which can make the warning device normally energized and send out a warning message.

Referring to shown in Fig. 19, for the present invention, in a kind of specific embodiment, in static contact group 52, any left and right symmetrically distributed two terminal posts 524 (for example in No. 1 and No. These two terminals 524) at the position are respectively connected to a positive terminal and a negative terminal of a warning device 100;

The positive terminal and the negative terminal of the warning device 100 are also respectively connected to the two ends of the external driving power.

Therefore, when due to the rotation of the moving contact frame 61 and the linkage shaft 7, the moving contact column 622 in the moving contact group 62 is inserted between the two static contacts (that is, between the left contact piece 522 and the right contact piece 523) , the two binding posts 524 of No. 1 and No. 2 are turned on, which is equivalent to the warning device being short-circuited. It should be noted that when the static and dynamic contacts are connected, the resistance is extremely small, which is equivalent to a wire. At this time, the current will directly flow through the two binding posts 524 at the positions of No. 1 and No. 2 of the static contacts, thus bypassing the warning device 100 . When the movable and static contacts are disconnected, that is, when the movable contact column 622 in the contact group 62 is no longer inserted between the two static contacts (that is, between the left contact piece 522 and the right contact piece 523), the current normally flows through the warning device 100 .

In terms of specific implementation, when the warning light is on, it can indicate that the hand crank is in the state of being taken out, and it can warn the on-duty personnel that there may be personnel who are manually operating the switch machine for maintenance outdoors.

The mechanical part only needs four screws to be installed on an external installation plane such as the wall of the control room, and the electrical part only needs to be connected in series to the switch of the existing switch control circuit. It can be used in the public loop of the electromechanical line (playing the role of a switch).

In specific applications, by connecting the device of the present invention in series in the common circuit of the switch machine motor line of the existing switch control circuit, when the hand crank is put in, the outdoor switch machine control circuit can be turned on (at this time, All multiple switch machines in the multi-machine traction turnout are powered normally), and when the hand crank is taken out, the outdoor switch machine control circuit can be automatically cut off (the outdoor switch machine control circuit is used as all multiple switch machines in the multi-machine traction switch The main power supply circuit of the switch machine, the device of the present invention is connected in series on the main power supply line, for example, in series on the power supply busbar), and the power supply of multiple switch machines can be cut off at the same time to protect the safety of the operator, so it can solve the problems in the prior art. , There is a safety risk when operating a single switch machine by hand in multi-machine traction turnouts. It can implement power-off protection when operating the switch machine by hand, and can effectively ensure personal safety when operating the switch machine by hand. .

In the present invention, in specific implementation, based on the moving contact group 62 and the static contact group 52 shown in FIG. 20 , two terminals 524 (1 No. and No. 2, or No. 3 and No. 4, or No. 5 and No. 6 terminals) are connected in series to the public circuit of the switch machine motor line of the existing switch control circuit, such as "6502 Electric Concentration" published by China Railway Press Circuit (revised version) "The switch machine motor line public loop of the switch control circuit recorded in ", of course, can also be the switch machine motor line public loop of other switch control circuits.

Among them, the common circuit of the switch machine motor line of the existing switch control circuit is used to control whether the motors of the multiple switch machines of the same group of switch are energized. This is its own control function and will not be repeated here.

In the present invention, in a specific implementation, in a specific embodiment, any left-right symmetrical distribution in the static contact group 52 is connected to the two terminal posts 524 (for example, in No. 1 and No. 2 positions) These two terminal posts 524) are connected in series on the common circuit 200 of the switch machine motor line of the existing switch control circuit, for example, connecting a section of the common circuit 200 of the switch machine motor line of the existing switch control circuit The two terminals obtained after the wires are disconnected are respectively connected to the two terminals 524 connected to the rear ends of any pair of contact strip groups symmetrically distributed in the static contact group 52 .

It should be noted that the device of the present invention is equivalent to a safety switch. When the hand crank is taken out from the device, the common circuit of the switch machine motor line of the existing switch control circuit is disconnected. At this time, the same group of switch The motors of multiple switch machines cannot be electrically operated.

Take the existing four-wire turnout control circuit as an example. When No. 1 and No. 2 (or No. 3 and No. 4, or No. 5 and No. 6) terminals 524 in the static contact group 52 of the device of the present invention are connected in series to the common circuit of the switch machine motor line of the switch control circuit , when the common circuit of the switch machine motor line is disconnected, the motors of multiple switch machines of the same group of switches cannot be powered. This is the working characteristic and function of the existing four-wire system switch control circuit, and will not be repeated here.

The above is only a preferred embodiment of the present invention, it should be pointed out that, for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications can also be made. It should be regarded as the protection scope of the present invention.
