Description

Technical Field

[0001] The invention relates to the technical field of railway coal transportation dust suppression equipment, in particular to a railway dust suppression spraying rocker arm device. Background Art

[0002] During the transportation of loose coal by railway, the coal dust particles on the surface are easily blown off the train body due to the speed of the coal train and the wind. It is very important to suppress the dust during the transportation of loose coal by railway. After the dust suppressant is sprayed on the surface of the coal, the fine dust particles will be bonded together, and a hard and highly adhesive solidified layer will form on the surface of the coal. The solidified layer itself is difficult to dissipate due to its bonding effect, and the coal below is also protected by the coverage of the solidified layer, thus achieving the dust suppression effect.

[0003] Most of the existing railway dust suppression spray rocker arm devices are located outdoors when in use. Since the time of railway coal transportation is not fixed, it will be affected by the outside weather. Especially when used in windy weather, under the influence of strong winds, the dust suppressant will deviate from the predetermined trajectory, resulting in uneven spraying of the dust suppressant, thereby reducing the dust suppression effect during coal transportation. To this end, we propose a railway dust suppression spray rocker arm device.

[0004] In view of the above problems, we found that it is difficult to avoid the above problems at the same time when using the existing railway dust suppression spray rocker arm device on the market. Moreover, even if it can be solved, it needs to be carried out with the cooperation of external tools, so it is impossible to achieve the desired effect. Therefore, we propose a railway dust suppression spray rocker arm device. Summary of the invention

Two connection springs 2103 and two telescopic rods 2104 are fixedly installed on the top and bottom surfaces of each connection block 2102. The telescopic rods 2104 are located inside the corresponding connection springs 2103. One end of each connection spring 2103 away from the connection block 2102 is fixedly installed with a moving seat 2105. The moving seat 2105 is slidably arranged on the outer surface of the rocker arm main body 2101. The telescopic end of each telescopic rod 2104 is fixedly connected to one side of the moving seat 2105 close to the connection block 2102. A connecting rod 2106 is rotatably hinged inside each moving seat 2105. The other ends of each set of connecting rods 2106 are rotatably hinged to a concave block 2107. A wind measuring plate 2108 is fixedly installed on one side of each set of concave blocks 2107 away from the connection block 2102. Two sets of connecting plates 2109 are fixedly installed on the outer surface of the rocker arm main body 2101. The number of each set of connecting plates 2109 is two. Four first fixing springs 2110 are fixedly installed on the outer surface of each connecting plate 2109. One end of the four first fixing springs 2110 away from the connecting plate 2109 is jointly fixedly installed with a first moving block 2111. A first touch switch 2112 is fixedly installed on the outer surface of each connecting plate 2109. A touch plate 2121 is fixedly installed on the outer surface of one set of moving seats 2105. An installation frame 2113 is fixedly installed on the inner wall of the rocker arm main body 2101. Two rotating motors 2114 are fixedly installed on the inner wall of the installation frame 2113. A worm 2115 is rotatably connected inside the installation frame 2113. The output end of one of the rotating motors 2114 is fixedly connected to one end of the worm 2115. A connecting frame 2116 is rotatably connected to the outer surface of the installation frame 2113. The output end of the other rotating motor 2114 is fixedly connected to the side wall of the connecting frame 2116. A rotating shaft 2117 is rotatably connected inside the connecting frame 2116. A worm gear 2118 is fixedly installed on the rotating shaft 2117. The worm gear 2118 meshes with the worm 2115. The output end of the left rotating motor 2114 penetrates through the connecting frame 2116 and is fixedly connected to the worm 2115. The left rotating motor 2114 controls the rotation of the worm 2115. The right rotating motor 2114 controls the rotation of the connecting frame 2116. Both ends of the rotating shaft 2117 pass through the connecting frame 2116 respectively and are fixedly connected to an adjusting frame 2119. A connection box 2120 is fixedly installed at the bottom of the adjusting frame 2119,Both ends of the fixed pipe 14 are fixedly connected to the inner wall of the connection box 2120. The first touch switch 2112 is electrically connected to the rotation motor 2114 through a wire. The two first touch switches 2112 in the front-back direction control the rotation motor 2114 on the right side, thereby adjusting the tilt angle of the connection box 2120 in the front-back direction. The two first touch switches 2112 in the left-right direction control the rotation motor 2114 on the left side, thereby adjusting the tilt angle of the connection box 2120 in the left-right direction. By means of the provided adjustment unit 21, the magnitude of the external wind force is monitored by using this device. Thus, when the external wind force reaches a certain magnitude, this device adjusts the spraying angle of the spray head 15, so that the sprayed dust suppressant can be sprayed at a predetermined position, avoiding the dust suppressant deviating from the predetermined landing point, and ensuring a good dust suppression effect on the coal.; The specific implementation of this embodiment is as follows: When in use, the worker first adds water source and dust suppressant raw materials into the storage tank 11, and then drives the stirring rod 16 to rotate by using the rotating motor 17 to stir and mix the raw materials inside the storage tank 11. When it is necessary to spray dust suppressant on the coal transported by train, the power provided by the water pump 12 is used to pump the raw materials inside the storage tank 11 into the conveying pipe 13, and then sprayed on the coal through the fixed pipe 14 and the nozzle 15. When encountering strong wind weather during the spraying of the dust suppressant, the wind force will squeeze the anemometer plate 2108, so that the anemometer plate 2108 moves towards the side close to the connecting block 2102, and then the anemometer plate 2108 drives the concave block 2107 to move towards the side close to the connecting block 2102. At the same time, the concave block 2107 drives the connecting rod 2106 to rotate at a certain angle, so that the connecting rod 2106 drives the moving seat 2105 to move away from the connecting block 2102. The moving seat 2105 drives the connecting spring 2103 to stretch, and at the same time the moving seat 2105 drives the touch plate 2121 to move. When the touch plate 2121 moves to the position of the first moving block 2111, the touch plate 2121 squeezes the first moving block 2111, so that the first moving block 2111 contacts the first touch switch 2112, and the first touch switch 2112 controls the rotation motor 2114 to operate. When the first touch switch 2112 in the front-back direction is triggered, the power provided by the right rotation motor 2114 is used to drive the connecting frame 2116 to rotate, so that the connecting frame 2116 cooperates with the adjusting frame 2119 to drive the connecting box 2120 to adjust the angle in the front-back direction, so that the nozzle 15 is inclined towards the direction where the wind blows, so that the position where the dust suppressant is sprayed on the coal is consistent with the predetermined position. Similarly, when the first touch switch 2112 in the left-right direction is triggered, the power provided by the left rotation motor 2114 is used to drive the worm 2115 to rotate, so that the worm 2115 drives the worm wheel 2118 to rotate, and then the worm wheel 2118 drives the rotating shaft 2117 and the adjusting frame 2119 to rotate in the left-right direction, and then adjusts the inclination angle of the connecting box 2120 in the left-right direction, so that the device is convenient to adjust the spraying angle according to different wind directions.

[0024] Embodiment 2: Please refer to Figures 1-12 , a swing arm device for railway dust suppression spraying, and the present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0025] As a further limitation of the swing arm mechanism 2 of the present invention, the swing arm mechanism 2 further includes a wind prevention unit 22. The wind prevention unit 22 is located inside the adjustment unit 21, and the adjustment unit 21 and the wind prevention unit 22 are used in cooperation. The wind prevention unit 22 plays a certain role in preventing wind for the nozzle 15; The windproof unit 22 includes four groups of second fixing springs 2201. The number of each group of second fixing springs 2201 is four. One end of each second fixing spring 2201 close to the connecting plate 2109 is fixedly connected to the connecting plate 2109. A second moving block 2202 is fixedly installed at the end of each group of second fixing springs 2201 away from the connecting plate 2109. A second touch switch 2203 is fixedly installed on the outer surface of each connecting plate 2109. A windproof shell 2204 is slidably connected to the outer surface of the connecting box 2120. Two L-shaped plates 2205 are fixedly installed on the upper surface of the connecting box 2120. Two fixing plates 2206 are fixedly installed on the inner top wall of each L-shaped plate 2205. A pulley 2207 is rotatably connected to one side surface of the two fixing plates 2206 close to each other. A traction rope 2208 is sleeved on the outer surface of each pulley 2207. One end of each traction rope 2208 is fixedly connected to the upper surface of the windproof shell 2204. An iron block 2209 is fixedly installed at the other end of each traction rope 2208. A first electromagnet 2210 is fixedly installed on the inner top wall of each L-shaped plate 2205. Two second electromagnets 2211 are fixedly installed on the upper surface of the connecting box 2120. Each second electromagnet 2211 is in contact with the iron block 2209 at the corresponding position. The second touch switch 2203 is electrically connected to the first electromagnet 2210 and the second electromagnet 2211 through wires, so that when the second touch switch 2203 is triggered, the power supply of the second electromagnet 2211 is disconnected, the first electromagnet 2210 is turned on, the iron block 2209 moves upward under the action of magnetism, and the iron block 2209 is in contact with the first electromagnet 2210. By providing the windproof unit 22, when the external wind force further increases, the device lowers the windproof shell 2204. If the height of the coal exceeds the height of the carriage, the bottom surface of the windproof shell 2204 is in contact with the upper surface of the coal. When the height of the coal does not exceed the carriage, the bottom surface of the windproof shell 2204 is in contact with the upper surface of the carriage, thereby reducing the influence of the wind force on the spraying trajectory of the dust suppressant, increasing the windproof effect of the nozzle 15, avoiding the deviation of the dust suppressant from the predetermined trajectory during spraying, and further ensuring the uniform spraying effect of the device in strong wind weather; Sliders 2212 are fixedly installed on one side surface of the two iron blocks 2209 close to each other. Two sliding grooves 2213 are formed in the inner wall of the L-shaped plate 2205. The two sliders 2212 are both slidably connected inside the sliding grooves 2213. The shape of the slider 2212 is T-shaped, and the shape of the sliding groove 2213 matches the shape of the slider 2212. The installation of the slider 2212 and the sliding groove 2213 plays a role in restricting the moving trajectory of the iron block 2209, thereby avoiding the phenomenon that the iron block 2209 deviates from the moving trajectory during movement, and further ensuring the stability of the movement of the iron block 2209; On the outer surface of each connecting plate 2109, two groups of telescopic columns 2214 are fixedly installed. The number of each group of telescopic columns 2214 is four. The telescopic ends of one group of telescopic columns 2214 are fixedly connected to the first moving block 2111. The two groups of telescopic columns 2214 are respectively located inside the first fixing spring 2110 and the second fixing spring 2201. The telescopic ends of the other group of telescopic columns 2214 are fixedly connected to the second moving block 2202. The installation of the telescopic columns 2214 plays a role in restricting the moving trajectories of the first moving block 2111 and the second moving block 2202, thus ensuring the stability of the movement of the first moving block 2111 and the second moving block 2202.

[0026] The specific implementation of this embodiment is as follows: When the moving seat 2105 is moving and the touch plate 2121 squeezes the second moving block 2202, the second moving block 2202 will trigger the second touch switch 2203, so that the second touch switch 2203 disconnects the power supply of the second electromagnet 2211 and turns on the power supply of the first electromagnet 2210, enabling the first electromagnet 2210 to adsorb the iron block 2209. Thus, under the action of magnetism, the iron block 2209 is driven to move upward. Then, under the action of the gravity of the windproof shell 2204, the windproof shell 2204 slides downward, thus achieving the effect of wind prevention for the nozzle 15. After the spraying of the dust suppressant is completed, the controller inside the rocker arm main body 2101 disconnects the power supply of the first electromagnet 2210 and turns on the power supply of the second electromagnet 2211, enabling the iron block 2209 to move downward under the action of its own gravity and the magnetic adsorption of the second electromagnet 2211. Then, the iron block 2209 pulls the traction rope 2208 to lift the windproof shell 2204, preventing the windproof shell 2204 from affecting the spraying range of the dust suppressant.

[0029] The specific implementation manner of this embodiment is as follows: When the adjustment unit 21 detects strong wind weather, the power provided by the servo motor 303 is used to drive the threaded rod 302 to rotate, thereby driving the moving box 304 and the pressing plate 305 to move upward. Since the third touch switch 306 faces downward, when the pressing plate 305 contacts the third touch switch 306 during the upward movement, the operation of the servo motor 303 is stopped, and the electric push rod 307 is turned on. The electric push rod 307 is used to drive the rack plate 308 to move toward the side away from the electric push rod 307, so that the rack plate 308 drives the connecting gear 310 to rotate, thereby causing the connecting gear 310 to drive the rotating shaft 309 and the first conical wheel 311 to rotate, and further driving the second conical wheel 313 to rotate, so that the second conical wheel 313 drives the bidirectional ball screw 312 connected thereto to rotate. At the same time, the bidirectional ball screw 312 drives the two moving plates 314 to move toward each other, so that the moving plates 314 cooperate with the clamping blocks 315 to clamp and fix the rocker arm main body 2101, avoiding the violent shaking of the rocker arm main body 2101 in strong wind weather, thereby preventing the dust suppressant from deviating from the spraying predetermined trajectory and ensuring the uniform spraying effect of the device.
