Description

Technical Field

[0001] The utility model belongs to the field of railway maintenance equipment, and in particular relates to an ice cone removal device for a bridge on a railway contact network. Background Art

[0002] Since the construction of the first electrified railway, the Baoji-Chengdu Line, in 1958, my country has experienced rapid development for decades. By 2012, the total mileage of electrified railways in my country exceeded 48,000 kilometers, surpassing the second-placed Russia and ranking first in the world. During the construction of electrified railways, a large number of overpasses were built, and dripping water inevitably occurred on both sides of the overpasses. In areas with lower latitudes or in summer, dripping water has little effect on the operation of railway trains, but in cold seasons, especially in some high-latitude areas, the dripping water problem poses a great safety hazard to train operation.

[0003] When the temperature is low in winter, dripping water will freeze to form icicles. When the icicles hanging from the top of the upper span extend to the height of the catenary cables above the contact network, and the ice exceeds the insulation length of the air, the icicles will discharge to the contact network, catenary cables and pantographs. If not discovered and removed in time, the contact network or catenary cables may be burned out in serious cases, which will have a great impact on the normal operation of the railway system.

[0004] The existing method of removing ice from upper bridges mostly adopts manual inspection and ice-breaking methods, which requires manual ice removal every hour. This method requires a large amount of manpower, and the working environment is harsh and dangerous for maintenance workers, posing a potential threat to the workers' life safety.

[0005] Based on this, the utility model proposes a device for removing ice cones across bridges on railway contact networks. Utility Model Content

[0041] The output shaft of the motor 8 passes through the lower housing 5 and the upper housing 1 and is fixed to one end of the driving rod 7. Specifically, a motor mounting hole is provided on the upper housing, the lower housing 5 is connected to the upper housing 1 through the motor mounting hole, and a sensor mounting opening is provided at the front end of the upper housing;

The body of the motor 8 is fixedly connected to the lower end surface of the upper shell 1.

[0043] The upper shell 1 is installed above the contact network, and the upper shell 1 extends in the horizontal direction. The upper shell 1 is provided with bolt holes extending up and down, and the bolt holes are isolated from the interior of the upper shell 1 to prevent water drops on the upper span from flowing into the upper shell 1 along the bolts.

The lower shell 5 is installed on the upper shell, and the lower shell 5 is sealed and fixed to the lower end surface of the upper shell 1;

[0044] A rotating block 3 is rotatably connected inside the upper shell 1. The rotating block 3 is installed at the swing opening. The rotating block 3 extends in the front-to-back direction. The front end face of the rotating block 3 is flush with the front end face of the upper shell 1. A circular groove is provided on the upper shell 1. A circular shaft is fixed to the rotating block 3. The circular shaft is rotatably connected in the circular groove.

The inner end of the deicing rod 2 is rotatably connected to the hinge shaft, so that the deicing rod 2 is hinged to the driving rod 7.

[0047] For further explanation of the present invention, see Figure 3 At least one side of the other end of the deicing rod 2 that contacts the ice cone is equipped with a hammer block, and the hammer block is used to hammer the ice cone.

[0048] For further explanation of the present invention, see Figure 3 The hammer block is integrally formed with the deicing rod 2, and the shape of the hammer block includes a triangle.

[0049] For further explanation of the present invention, see Figure 4 A control assembly 9 is installed on the lower housing 5 , and the control assembly 9 is electrically connected to the motor 8 . The control assembly 9 is used to control the rotation of the output shaft of the motor 8 .

[0050] For further explanation of the present invention, see Figure 4A sensor 4 is installed on the lower shell 5, and the sensor 4 is electrically connected to the control assembly 9. The sensor 4 is used to detect ice cones and transmit the signal of the detected ice cones to the control assembly 9.

[0051] Among them, in this embodiment, the control assembly 9 is installed on the lower end surface of the upper shell 1 and is located in the lower shell 5. By setting the control assembly, the motor 8 can be controlled to operate once at a certain interval. The upper shell 1 is equipped with a sensor 4 for detecting ice cones. The sensor 4 adopts an infrared sensor. The sensor 4 is installed at the sensor installation port, and the upper, lower, left and right end surfaces of the sensor 4 are respectively sealed and fixed with the lower shell 5. The sensor 4 faces the ice cone. The sensor 4 can sense the ice cone above the contact network. The body of the sensor 4, the control assembly 9, and the motor 8 are all installed in the lower shell 5. The lower shell 5 can prevent the line from getting damp. The sensor is electrically connected to the motor 8 and the control assembly 8 respectively. After the sensor 4 detects the ice cone, it transmits a signal to the control assembly 9, and the control assembly 9 controls the motor 8 to operate.

[0052] For further explanation of the present invention, see Figure 4 A camera 6 is installed on the lower surface of the upper shell 1, and the camera 6 faces the side with the ice cone.

[0053] Among them, in this embodiment, the camera 6 is rotatably connected to the lower end surface of the upper shell 1, and the camera 6 faces the side with the ice cone. The camera 6 takes pictures of the contact network at regular intervals and uploads them to facilitate the staff to understand the on-site conditions.

[0054] For further explanation of the present invention, see Figure 4 , the width of the upper shell 1 is greater than twice the length of the driving rod 7.

[0055] Among them, according to the utility model, when the driving rod 7 extends backward and the extension direction of the de-icing rod 2 is consistent with that of the driving rod 7, the de-icing rod 7 is in the shortest contracted state. When the de-icing rod 7 is in the shortest contracted state, the outer end of the de-icing rod 7 is located at the bottom of the upper bridge. As the driving rod 7 rotates, the de-icing rod 7 extends out of the bottom of the upper bridge and can extend to the outside of the ice cone.

[0056] For further explanation of the present invention, see Figure 4 , the sensor 4 includes an infrared sensor.

[0057] During use, this embodiment is installed at the bottom of the upper span bridge and directly above the contact network, so that the de-icing rod 2 is located at the bottom of the upper span bridge in the shortest contraction state. When the sensor 4 detects the ice cone, the sensor 4 transmits a signal to the control assembly, and the control assembly 9 controls the motor 8 to rotate clockwise, and the driving rod 7 rotates clockwise and drives the de-icing rod 2 to move. The outer end of the de-icing rod 2 extends outward while turning left. As the driving rod 7 rotates, the de-icing rod 2 swings to the right. The de-icing rod 2 completes the interruption of the ice cone during the rightward swing. Due to the characteristics of this driving mechanism, the speed of the de-icing rod 2 will increase when it swings to the right, so that the ice cone is easier to be interrupted. The driving rod 7 rotates one circle, and the de-icing rod 2 completes the de-icing action and retracts to the bottom of the upper span bridge.

[0058] The camera 6 can take pictures of the scene, making it convenient for the staff to understand the situation on the scene. The staff can remotely control the action of the motor 8 through the control assembly. By setting the control assembly 9, the motor 8 can be controlled to act once at a certain interval. If the ice cone is not broken when the de-icing rod 2 hits the ice cone, the motor will be stuck for 2 seconds, and the control assembly 9 will control the motor to reverse to the initial position and rotate forward again to hit the ice cone.
