AI Technical Summary
In narrow-gauge transportation in underground mines, the lack of clear instructions when locomotives enter and exit single-track sections can lead to potential collisions and pose safety hazards.
The system uses a rotating balance iron to switch the mercury switch on and off, controlling the indicator lights to turn on or off. The circuit's switching state is changed through contact between the contact frame and the locomotive, indicating whether the locomotive can pass safely.
It effectively avoids collisions of electric locomotives on one-way roads, ensures the safe passage of electric locomotives, and has a simple and easy-to-implement structure.

DETAILED DESCRIPTION
[0012] In order to make the purpose, technical scheme and advantages of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the embodiment. Obviously, the described embodiment is a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0013] The underground mine tunnel signal lamp control device contains contact frame 1, connecting rod 3, U-shaped iron 4, mercury switch 5, welded pipe 6, balance ball 7, perforated steel plate 8 and positioning pin 9. The welded pipe 6 is a sealed welded pipe at both ends. The balance ball 7 is placed inside the welded pipe 6. The perforated steel plate 8 is welded in the middle part of the welded pipe 6. The welded pipe 6, the balance ball 7 and the perforated steel plate 8 constitute a balance iron. The U-shaped iron 4 and the perforated steel plate 8 are connected through the positioning pin 9. The welded pipe 6 is rotationally arranged around the positioning pin 9. The U-shaped iron 4 and the connecting rod 3 are welded and connected. The connecting rod 3 is fixed on the ceiling. The mercury switch 5 is installed on the welded pipe 6. The contact frame 1 is fixed on the top of the electric locomotive. The contact frame 1 and the balance iron are matched.
[0014] It also contains two steel wires 2. The ends of the two steel wires 2 are connected to the two ends of the welded pipe 6 respectively. The top ends of the steel wires 2 are fixed on the ceiling.
[0015] The length of the steel wire 2 matches the rotation angle of the welded pipe 6.
[0016] The contact frame 1 is a rectangular frame made of square steel.
[0017] In actual application, the balance ball 7 is put into the welded pipe 6. Then the two ends of the welded pipe 6 are sealed. A 15mm thick perforated steel plate 8 is welded in the middle part of the welded pipe 6. The welded device is named balance iron. A perforated U-shaped iron 4 connects the balance iron together with the positioning pin 9. The U-shaped iron 4 and the connecting rod 3 are welded together. Finally, the connecting rod 3 is fixed to the ceiling.
[0018] The balance iron is connected to the ceiling by two steel wires 2 at both ends, leaving a proper length to make the balance iron swing to the maximum without affecting the operation of the electric locomotive.
[0019] After the reconstruction of the overhead line section, a rectangular contact frame 1 is made of square steel and welded on the top of the electric locomotive for actuating the balance iron.
[0020] The operator installs the utility model in place, and places the welded pipe at an angle of welded pipe deflection direction one 14, so that the mercury switch 5 is in the closed state.
[0021] When the electric locomotive runs in the direction of the mine along the direction of travel 10, the contact frame collides with the downward end of the welded pipe when the contact frame is at the contact frame position one 12, and the welded pipe deflection direction is changed to the angle of welded pipe deflection direction two 15 as the electric locomotive passes, at which time the mercury switch is in the open state, so that the circuit is connected to the signal lamp, and other electric locomotives that need to pass through this section know that there is a vehicle waiting outside.
[0022] When the entering electric locomotive runs in the direction of the mine along the direction of travel 11, the contact frame moves from the contact frame position one 12 to the contact frame position two 13, and when the contact frame reaches the contact frame position two 13, it collides with the downward end of the welded pipe as the electric locomotive runs, and the welded pipe deflection direction is changed to the angle of welded pipe deflection direction one 14 as the electric locomotive passes, at which time the mercury switch is in the closed state, so that the circuit is disconnected and the signal lamp is off, so that other electric locomotives that need to pass through this section know that there is no vehicle inside, so that they can safely enter.
[0023] The utility model connects the U-shaped iron and the welded pipe, so that the welded pipe can be deflected as the electric locomotive enters and exits, causing the mercury switch at the top of the welded pipe to change from the closed state to the open state, thereby realizing the function of controlling the circuit switch. When the electric locomotive enters the mine, the deflection of the welded pipe causes the mercury switch to be in the closed state, so that the circuit is connected and the signal lamp is on. When the electric locomotive exits the mine, the welded pipe is knocked back to its original state, causing the mercury switch to be disconnected, so that the circuit is disconnected and the signal lamp is off. The device can prevent the occurrence of a collision accident caused by two electric locomotives entering a single lane at the same time.
