[0002] EMU relay is an important component used in the EMU electrical control system, used to control various electrical equipment and systems of the EMU. EMU relays usually include two types: control relays and protection relays. Since there is no special tooling to force the relay to close, mechanics use various methods, such as inserting cable ties, wooden boards, keys, etc. into the gaps between the relays to force the relay to close, but the reliability is poor and secondary failures may occur. If metal such as keys is used, there are also safety hazards.

[0003] After searching, a Chinese patent with announcement number CN218258158U discloses a relay strong suction tool. The strong suction tool provided by the utility model can shorten the time for handling relay failures, handle relay failures in a short time, quickly restore the functional status of the electrical control circuit of the EMU, and avoid the situation where the EMU cannot run due to relay failure.

[0004] When the above patent is used, the coil wire is wound on the suction coil seat of the relay strong suction tool, then led out from the outlet, and finally connected to the fault relay coil terminal, which is complicated to operate and increases the labor intensity of the staff.

[0027] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Refer to the instruction manual Figure 1-6The EMU relay forced closing device of this embodiment includes a relay body 1 and a connecting bolt 2, and the connecting bolt 2 is threadedly connected to the relay body 1. The bottom end of the relay body 1 is fixedly connected to a limit frame 3, and a fixed frame 4 is movably arranged inside the limit frame 3. Two batteries 11 and a conductive column 10 are installed inside the fixed frame 4. The two batteries 11 and the conductive column 10 are electrically connected, and the top of the conductive column 10 extends into the relay body 1. A moving component 6 is provided on the limit frame 3, and the moving component 6 includes positive and negative screw rods 601, two sliders 602, a slide bar 603, four L-shaped plates 606 and four plug blocks 607.

[0029] Furthermore, both ends of the forward and reverse screw rods 601 are movably connected to the limit frame 3 through bearings, both ends of the slide rod 603 are fixedly connected to the limit frame 3, and one end of the forward and reverse screw rods 601 and the slide rod 603 pass through the two sliders 602, one side of the four L-shaped plates 606 are respectively fixedly connected to the two sliders 602, one end of the four plug blocks 607 are respectively fixedly connected to the four L-shaped plates 606, and the other ends of the four plug blocks 607 are inserted into the fixed frame 4, and a handle 604 is provided on one side of the limit frame 3, and one side of the handle 604 is fixedly connected to the forward and reverse screw rods 601.

[0030] Furthermore, gaskets 605 are fixedly connected to the opposite sides of the two sliders 602, and the top ends of the two gaskets 605 are in contact with the relay body 1. Four side plates 7 are fixedly connected to the inside of the limit frame 3, and the bottom ends of the four side plates 7 are in contact with the fixed frame 4. When the two sliders 602 are in contact, the two gaskets 605 seal the bottom of the relay body 1, and the four side plates 7 limit the upward movement distance of the fixed frame 4.

[0031] Furthermore, a warning component is provided on the limit frame 3, and the warning component includes two warning lights 5, two threaded iron rods 8 and two threaded sleeves 9. The opposite ends of the two threaded iron rods 8 are respectively fixedly connected to the two warning lights 5, and the facing ends of the two threaded iron rods 8 are inserted into the limit frame 3, and the two threaded sleeves 9 are respectively movably mounted on the two threaded iron rods 8.

[0032] Among them, the threaded iron rod 8 is inserted into the limit frame 3, and then the threaded sleeve 9 is rotated and sleeved on the threaded iron rod 8, so that the warning light 5 is fixed to the limit frame 3. When the relay body 1 leaks electricity, the current enters the warning light 5 through the threaded iron rod 8, and the warning light 5 emits a bright light to remind the staff to pay attention to safety. The structure is simple and the safety performance is high.

[0033] The method of using this embodiment is:

[0034] When in use, the handle 604 is turned to drive the forward and reverse screw rods 601 to rotate. Since the two sliders 602 are both threadedly connected to the forward and reverse screw rods 601, the slide rod 603 limits the rotation of the two sliders 602. Therefore, the forward and reverse screw rods 601 can drive the two sliders 602 to move away from each other, thereby driving the four L-shaped plates 606 to move horizontally, and then the fixed frame 4 is inserted into the limit frame 3, and the top of the conductive column 10 contacts the excitation coil inside the relay body 1, thereby generating a magnetic field, forcing the relay body 1 to be forced to attract. Similarly, the reverse handle 604 drives the two sliders 602 to move toward each other, and allows the four plug blocks 607 to be inserted into the fixed frame 4, so that the fixed frame 4 is fixed to the limit frame 3. The operation is simple and the labor intensity of the staff is effectively reduced.
