[0002] In metallurgical enterprises, railway transportation is an indispensable and important mode of transportation. Railway turnouts are the throat of railway operation. The turnout conversion is achieved by driving the switch to extend and retract the close-fitting adjustment rod. The tongue iron is connected to the railway turnout by bolts. When the switch machine is running, the rod body can be pushed and pulled. With the help of the nut on the rod body, the tongue iron can be pushed and pulled. The tongue iron can push and pull the railway turnout to move the railway turnout. Because the transport vehicle is heavy and vibrates greatly, when passing through the turnout section, it is easy to cause the large nut fastened by the close-fitting adjustment rod to loosen, which is likely to cause the point rail and the base rail to not fit closely, causing the locomotive wheels to impact the tip of the point rail, and also causing the wheel load to be transferred from the base rail to the point rail prematurely, which is easy to cause turnout failure and seriously affect driving safety and stability.

[0003] At present, the close-fitting adjustment rod used mainly relies on the front and rear large nuts to tighten and lock after the turnout adjustment is completed to prevent the point rail from not fitting tightly against the base rail. However, due to the weight and vibration of the vehicle, the nuts are easily loosened, resulting in the point rail and the base rail not fitting tightly, affecting driving safety.

[0018] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0019] See also Figure 1-3 As shown, a close-fitting adjustment rod with an anti-slip device of the utility model comprises a rod body 1, an outer surface of the rod body 1 is provided with an external thread, the rod body 1 is threadedly connected with a tongue iron 2, a plurality of locking nuts 3 for locking the tongue iron 2 are threadedly connected to the rod body 1 on both sides of the tongue iron 2, a round wire elastic retaining ring 4 is sleeved on the rod body 1 outside the locking nut 3, the round wire elastic retaining ring 4 is provided with an axially arranged bent lock 9, a key groove 8 adapted to the bent lock 9 is opened on the rod body 1, and the bent lock 9 is embedded in the key groove 8. After the close-fitting adjustment between the turnout point rail and the basic rail is completed and the locking nut 3 of the rod body 1 is tightened, the round wire elastic retaining ring 4 with the bent lock 9 is rotated along the thread of the rod body 1 to the root of the locking nut 3, and the bent lock 9 is wedge-fitted with the key groove 8 to generate a circumferential moment and a circular moment. The elastic friction of the linear elastic retaining ring 4 acts on the whole at the same time to prevent the locking nut 3 from loosening, which can effectively prevent the locking nut 3 from loosening, thereby avoiding the point rail and the basic rail from not being close together and affecting the driving safety. At the same time, the point rail and the basic rail are more closely together, reducing wear and tear and increasing the service life of the point rail. At the same time, by setting an extrusion block 13, the extrusion block 13 is squeezed under the round wire elastic retaining ring 4, so that the round wire elastic retaining ring 4 is in an extruded state, making it difficult for the round wire elastic retaining ring 4 to loosen, thereby playing a reinforcing role. By setting a photoelectric sensor 11 and an alarm 12, after the extrusion block falls off, the photoelectric sensor 11 transmits a signal to the controller, and the controller controls the alarm 12 to sound, thereby reminding personnel to repair as soon as possible, effectively avoiding the occurrence of accidents.

[0020] Specifically, a washer 5 sleeved on the rod body 1 is provided between the tongue iron 2 and the locking nut 3, and a protrusion 7 is provided on the washer 5. A groove 6 adapted to the protrusion 7 is opened on the tongue iron 2, and the protrusion 7 is inserted in the groove 6. The washer 5 makes the locking nut 3 more stressed when tightened, so that the locking nut 3 can be tightened more. The protrusion 7 and the groove 6 cooperate to make the washer 5 unable to rotate, effectively preventing the washer 5 from driving the locking nut 3 to rotate, thereby achieving a better anti-slip effect.

[0021] Preferably, an extrusion groove 10 is provided on one side of the outer surface of the rod body 1, and an extrusion block 13 is provided in the extrusion groove 10. An inclined structure is provided on the upper surface of the extrusion block 13, which squeezes the extrusion block 13 under the round wire elastic retaining ring 4, so that the round wire elastic retaining ring 4 is in an extruded state, making it difficult for the round wire elastic retaining ring 4 to loosen, thereby playing a reinforcing role.

[0022] Furthermore, the rod body 1 is respectively provided with a photoelectric sensor 11, and the detection end of the photoelectric sensor 11 is irradiated on the tail of the extrusion block 13. The photoelectric sensor 11 is electrically connected to an external controller, and the controller is electrically connected to the alarm 12. By arranging the photoelectric sensor 11 and the alarm 12, after the extrusion block falls off, the photoelectric sensor 11 transmits a signal to the controller, and the controller controls the alarm 12 to make a sound, thereby reminding personnel to repair as soon as possible and effectively avoiding the occurrence of accidents.

[0023] Furthermore, there are four locking nuts 3, which are divided into two groups and are respectively threadedly connected to both sides of the rod body 1, and a double-nut locking method is adopted, so that the locking is more secure.

[0024] When the close-fitting adjustment rod with an anti-skid device of the present embodiment is used, after the close-fitting adjustment between the turnout point rail and the base rail is completed, the locking nut 3 of the rod body 1 is tightened, and then the round wire elastic retaining ring 4 with the bent lock 9 is rotated along the thread of the rod body 1 to the root of the locking nut 3, and the bent lock 9 and the keyway 8 are wedge-fitted to generate the circumferential force moment and the elastic friction force of the round wire elastic retaining ring 4 act on one body at the same time to prevent the locking nut 3 from loosening, which can effectively prevent the locking nut 3 from loosening, thereby avoiding the point rail and the base rail from not being in close contact and affecting driving safety. The point rail and the base rail are more closely fitted, the wear is reduced, and the service life of the point rail is increased. At the same time, by setting the extrusion block 13, the extrusion block 13 is squeezed under the round wire elastic retaining ring 4, so that the round wire elastic retaining ring 4 is in an extruded state, and the round wire elastic retaining ring 4 is difficult to loosen, which plays a reinforcing role. By setting the photoelectric sensor 11 and the alarm 12, after the extrusion block falls off, the photoelectric sensor 11 transmits a signal to the controller, and the controller controls the alarm 12 to make a sound, thereby reminding personnel to repair as soon as possible, effectively avoiding the occurrence of accidents. The utility model is a close-fitting adjustment rod with an anti-skid device, which effectively solves the safety hazard of non-close-fitting caused by loose nuts, and has the characteristics of wide application range and strong practicality.
