Description

Technical Field

[0001] This utility model relates to the field of snow removal technology for railway turnouts, specifically a snow removal nozzle for railway turnouts. Background Technology

[0002] Railway turnouts are key pieces of equipment in a track system, used to guide trains from one track to another, enabling flexible switching and crossing of lines. They consist of switches (point rail, stock rail), frogs (frog rail, wing rail), connecting parts, and sleepers, and change the train's direction of travel through mechanical or electric control of the point rail movement. To ensure safety during track switching, snow accumulation on the turnouts needs to be cleared.

[0003] In the prior art, the authorized announcement number CN206233169U discloses a snow removal machine for railway turnouts, including an air supply pipe, at least one blower pipe disposed on the air supply pipe, a fan disposed at one end of the air supply pipe, and a signal receiver connected to the fan. The blower pipe is disposed below the air supply pipe, a solar panel is disposed on the surface of the air supply pipe, and a battery is disposed on the air supply pipe. The battery is connected to the solar panel and the fan.

[0004] The aforementioned device uses a blower to deliver airflow into the gap between the main rail and the switch rail of the turnout, thereby blowing away the snow accumulated in the track gap. However, the blower is in a fixed state and can only blow airflow in a specific direction, which means that many areas within the narrowed track area cannot be effectively cleaned by the airflow, resulting in incomplete cleaning. Therefore, a snow removal nozzle for railway turnouts is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a snow removal nozzle for railway turnouts to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a snow removal nozzle for railway turnouts, comprising a turnout rail, a first clamp on one side of the turnout rail, and a second clamp on the other side of the turnout rail, wherein a fixing bolt is installed between the first clamp and the second clamp, and a nozzle assembly is fixedly installed on the second clamp, the nozzle assembly comprising a cylindrical shell fixedly installed on the second clamp, an inner shell rotatably installed inside the cylindrical shell, a nozzle fixedly installed on the inner shell, a movable notch being provided on the cylindrical shell, and the nozzle extending out of the cylindrical shell through the movable notch, and a driving mechanism being provided on the cylindrical shell.

[0007] Preferably, the nozzle assembly further includes a positioning base fixedly installed at the bottom of the cylindrical housing, a connection interface is provided on one side of the cylindrical housing, an elbow is connected inside the connection interface, and a sealing ring is provided at the connection between the cylindrical housing and the inner housing.

[0008] Preferably, the second clamp has a threaded groove, and the positioning base is connected to the second clamp through the threaded groove.

[0009] Preferably, the first clamp and the second clamp are fixed to the turnout rail by fixing bolts, the cylindrical shell is fixed to the second clamp by a positioning base, the elbow is connected to the cylindrical shell by a mating interface, and an air supply pipe is connected to the elbow.

[0010] Preferably, the drive mechanism includes an internal gear ring fixedly mounted on the inner housing and a positioning support rotatably mounted on the cylindrical housing. A torsion spring is sleeved on the positioning support. A pinion is fixedly mounted on one end of the positioning support, and a rotating arm is fixedly mounted on the other end of the positioning support. A linkage cable is fixedly mounted on the rotating arm.

[0011] Preferably, the cylindrical shell has a movable hole, and the positioning support is rotatably mounted on the cylindrical shell through the movable hole.

[0012] Preferably, the pinion is rotatably mounted inside the cylindrical housing via a positioning support, and the pinion meshes with the internal gear ring. One end of the torsion spring is fixedly mounted on the positioning support, and the other end of the torsion spring is fixed on the cylindrical housing. A fixing hole is provided on the rotating arm, and the linkage cable is connected to the rotating arm through the fixing hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, when the snow accumulation is large, air is supplied to the interior of the cylindrical shell through a blower, and the air is finally ejected at high speed through a nozzle. The high-speed air jet can effectively remove snow from the track gaps, thus achieving the cleaning operation. In addition, by rotating the inner shell, the jet angle of the nozzle can be adjusted, thereby changing the direction of the airflow to thoroughly clean all areas of the track gaps.

[0015] 2. In this application, multiple rotating arms can be synchronously rotated by pulling the linkage cable. When these rotating arms move in tandem, the positioning support pillar will rotate accordingly. The rotation of the positioning support pillar further drives the pinion gear to rotate, which in turn causes the internal gear ring to rotate. The rotation of the internal gear ring ultimately causes the inner housing to rotate, thereby causing multiple nozzles to slowly rise, completing the bottom-up blowing process and effectively improving cleaning efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a snow removal nozzle for railway turnouts, including a turnout rail 1, a first clamp 2 on one side of the turnout rail 1, and a second clamp 4 on the other side of the turnout rail 1. A fixing bolt 3 is installed between the first clamp 2 and the second clamp 4. A nozzle assembly 5 is fixedly installed on the second clamp 4, and a drive mechanism 6 is provided on the cylindrical housing 501. By using the nozzle assembly 5 in conjunction with the drive mechanism 6, the oscillating nozzle 503 can sweep the rail, improving the cleaning effect.

[0023] like Figure 2 and Figure 3 As shown, the nozzle assembly 5 includes a cylindrical housing 501 fixedly mounted on the second clamp 4, an inner housing 502 rotatably mounted inside the cylindrical housing 501, a nozzle 503 fixedly mounted on the inner housing 502, a movable notch 505 opened on the cylindrical housing 501, and the nozzle 503 extends out of the cylindrical housing 501 through the movable notch 505. The nozzle assembly 5 also includes a positioning base 504 fixedly mounted on the bottom of the cylindrical housing 501, a connecting interface 507 opened on one side of the cylindrical housing 501, an elbow 508 connected inside the connecting interface 507, and a sealing ring 506 provided at the connection between the cylindrical housing 501 and the inner housing 502.

[0024] Specifically, in cases of heavy snow accumulation, air can be delivered into the cylindrical housing 501 using a blower. This air, once inside the housing 501, is then ejected at high speed through the nozzle 503. As the air is ejected at high speed through the nozzle 503, it effectively blows away snow from the track gaps, thus achieving the purpose of snow removal. Furthermore, the angle of the nozzle 503 can be adjusted by rotating the inner housing 502, thereby changing the direction of the airflow. This method allows for convenient and thorough cleaning of all parts of the track gaps, ensuring the cleanliness and safety of the tracks.

[0025] like Figure 2 and Figure 4 As shown, the drive mechanism 6 includes an internal gear ring 606 fixedly mounted on the inner housing 502 and a positioning support 603 rotatably mounted on the cylindrical housing 501. A torsion spring 604 is sleeved on the positioning support 603. A pinion 605 is fixedly mounted on one end of the positioning support 603, and a rotating arm 602 is fixedly mounted on the other end of the positioning support 603. A linkage cable 601 is fixedly mounted on the rotating arm 602. A movable hole is provided on the cylindrical housing 501. The positioning support 603 is rotatably mounted on the cylindrical housing 501 through the movable hole. The pinion 605 is rotatably mounted inside the cylindrical housing 501 through the positioning support 603, and the pinion 605 meshes with the internal gear ring 606. One end of the torsion spring 604 is fixedly mounted on the positioning support 603, and the other end of the torsion spring 604 is fixed on the cylindrical housing 501.

[0026] Specifically, pulling the linkage cable 601 synchronizes the rotation of multiple rotating arms 602. As these rotating arms 602 begin to rotate in tandem, they sequentially transmit power, causing the positioning support column 603 to rotate as well. The rotation of the positioning support column 603 further drives the pinion gear 605 to rotate. The rotation of the pinion gear 605 in turn causes the internal gear ring 606 to rotate, which in turn drives the inner housing 502 to rotate. This series of mechanical actions ultimately causes multiple nozzles 503 to slowly lift, achieving a bottom-up blowing process that significantly improves the cleaning effect. When the linkage cable 601 is released, the torsion spring 604 automatically activates, causing the positioning support column 603 to return to its initial position. The resetting action of the positioning support column 603 then drives the nozzles 503 back to their original positions, completing the reset action of the entire cleaning process.

[0027] Working principle: During use, the nozzle assembly 5 is installed at intervals in the gap between the main rail and the switch point rail, and the air pipe is connected to the cylindrical housing 501 through the elbow 508. When there is a lot of snow, air can be sent into the cylindrical housing 501 through the air pipe. The air sent into the cylindrical housing 501 will eventually be ejected at high speed through the nozzle 503. The high-speed air ejected through the nozzle 503 will sweep away the snow in the rail gap, thereby cleaning the snow. The inner housing 502 can be rotated to adjust the angle of the nozzle 503 and change the airflow direction, which is convenient for cleaning all parts of the rail gap. Simultaneously, the user can pull the linkage cable 601 to make multiple rotating arms 602 rotate synchronously. When multiple rotating arms 602 rotate synchronously, they will drive the positioning pillar 603 to rotate. After the positioning pillar 603 rotates, it will drive the pinion 605 to rotate. After the pinion 605 rotates, it will drive the internal gear ring 606 to rotate. After the internal gear ring 606 rotates, it will drive the inner housing 502 to rotate, thereby causing multiple nozzles 503 to slowly rise, achieving bottom-up blowing and improving the cleaning effect. After releasing the linkage cable 601, the torsion spring 604 will drive the positioning pillar 603 to reset. After the positioning pillar 603 resets, it will drive the nozzles 503 to reset.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
