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 spray rocker arm device. Background Art

[0002] During the transportation of loose coal by rail, the speed of the coal train and the effects of wind can easily cause coal dust particles on the surface to be blown off the train. Suppressing dust during rail transport of loose coal is crucial. When dust suppressants are sprayed on the surface of the coal, they bind the fine dust particles together, forming a hard, highly cohesive solidified layer. This cohesive layer prevents it from escaping, and the underlying coal is also protected by the solidified layer, effectively suppressing dust.

[0003] Existing railway dust suppression spraying rocker arm devices are mostly used outdoors. Since railway coal transportation schedules are irregular, they are subject to weather influences. Especially when used in windy conditions, strong winds can cause the dust suppressant to deviate from its intended trajectory, resulting in uneven spraying and reduced dust suppression effectiveness during coal transportation. To address this issue, we propose a railway dust suppression spraying rocker arm device.

[0004] In light of the above issues, we found that the existing railway dust suppression spray rocker arm devices on the market are difficult to simultaneously avoid when used. Moreover, even if they can be solved, they require the use of external tools, thus failing to achieve the desired effect. Therefore, we propose a railway dust suppression spray rocker arm device.

The interior of each movable seat 2105 is rotatably hinged with a connecting rod 2106, and the other end of each group of connecting rods 2106 is rotatably hinged with a concave block 2107. Each group of concave blocks 2107 is fixedly installed with a wind measuring plate 2108 on one side away from the connecting block 2102. Two groups of connecting plates 2109 are fixedly installed on the outer surface of the rocker arm body 2101. There are two plates 2109, and four first fixed springs 2110 are fixedly installed on the outer surface of each connecting plate 2109. The four first fixed springs 2110 are fixedly installed with a first moving block 2111 at one end away from the connecting plate 2109. A first touch switch 2112 is fixedly installed on the outer surface of each connecting plate 2109, and a touch plate 2121 is fixedly installed on the outer surface of one group of moving seats 2105. A mounting bracket 2113 is fixedly installed on the inner wall of the rocker arm body 2101, and two rotating motors 2114 are fixedly installed on the inner wall of the mounting bracket 2113. The internal rotation of the mounting bracket 2113 is connected to a worm 2115, and the output end of one rotating motor 2114 is fixedly connected to one end of the worm 2115. The outer surface of the frame 2113 is rotatably connected to the connecting frame 2116, and the output end of another rotating motor 2114 is fixedly connected to the side wall of the connecting frame 2116. The internal rotatable connection of the connecting frame 2116 is connected to the rotating shaft 2117. A worm gear 2118 is fixedly installed on the rotating shaft 2117. The worm gear 2118 is meshed with the worm 2115. The output end of the left rotating motor 2114 passes 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, and the right rotating motor 2114 controls the rotation of the connecting frame 2116. The two ends of the rotating shaft 2117 respectively pass through the connecting frame 2116 and are fixedly connected to the adjusting frame 2119. The bottom of the adjusting frame 2119 is fixedly installed with a connecting box 2120.Both ends of the fixed tube 14 are fixedly connected to the inner wall of the connection box 2120. The first touch switch 2112 is electrically connected to the rotating motor 2114 via a wire.

The two first touch switches 2112 in the left-to-right direction control the rotating motor 2114 on the left side, thereby adjusting the tilt angle of the connection box 2120 in the left-to-right direction. The adjustment unit 21 is provided to monitor the size of the external wind force. When the external wind force reaches a certain level, the device adjusts the spraying angle of the nozzle 15 so that the sprayed dust suppressant can be sprayed at a predetermined position, thereby preventing the dust suppressant from deviating from the predetermined landing point and ensuring a good dust suppression effect on the coal.

[0039] The specific implementation of this embodiment is as follows: when in use, the worker first adds water and dust suppressant raw materials to the interior of the storage tank 11, and then uses the rotating motor 17 to drive the stirring rod 16 to rotate to stir and mix the raw materials inside the storage tank 11. When it is necessary to spray dust suppression on the coal transported by train, the power provided by the water pump 12 is used to extract the raw materials inside the storage tank 11 into the interior of the conveying pipe 13, and then spray them on the coal through the fixed pipe 14 and the nozzle 15. When encountering strong winds during the dust suppressant spraying process, the wind will squeeze the wind measuring plate 2108, The wind measuring plate 2108 moves toward the side close to the connecting block 2102, and then the wind measuring plate 2108 drives the concave block 2107 to move toward 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 extend. At the same time, the moving seat 2105 drives the touch plate 2121 to move. When the touch plate 2121 moves to the first moving When the first moving block 2111 is in 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, so that the first touch switch 2112 controls the rotation motor 2114 to operate. When the first touch switch 2112 in the front and rear 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 adjustment frame 2119 to drive the connecting box 2120 to adjust the angle in the front and rear direction, so that the nozzle 15 is tilted toward The direction of 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 and right directions is triggered, the power provided by the left rotating 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 and right directions, and then adjusts the inclination angle of the connecting box 2120 in the left and right directions, so that the device can easily adjust the spraying angle according to different wind directions.

[0040] Example 2: Please refer to Figure 1-12 , a railway dust suppression spraying rocker arm device, the present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0041] As a further limitation of the rocker arm mechanism 2 of the present invention, the rocker arm mechanism 2 further includes a windproof unit 22, which is located inside the adjustment unit 21. The adjustment unit 21 and the windproof unit 22 are used in conjunction with each other to provide a certain degree of windproofing for the nozzle 15.

[0042] The windproof unit 22 includes four groups of second fixed springs 2201, each group of second fixed springs 2201 has four, each second fixed spring 2201 is fixedly connected to the connecting plate 2109 at one end thereof, and a second moving block 2202 is fixedly installed at one end of each group of second fixed springs 2201 away from the connecting plate 2109, and a second touch switch 2203 is fixedly installed on the outer surface of each connecting plate 2109, and a windproof shell 2204 is slidably connected to the outer surface of the connecting box 2120, and the upper surface of the connecting box 2120 is fixedly connected to the windproof shell 2204. Two L-shaped plates 2205 are fixedly installed, and two fixed plates 2206 are fixedly installed on the inner top wall of each L-shaped plate 2205. The side of the two fixed plates 2206 close to each other is rotatably connected to a pulley 2207. The outer surface of each pulley 2207 is sleeved with a traction rope 2208. One end of each traction rope 2208 is fixedly connected to the upper surface of the windproof shell 2204, and the other end of each traction rope 2208 is fixedly installed with an iron block 2209. The inner top wall of each L-shaped plate 2205 is fixedly installed with a first electromagnet 2210, which is connected Two second electromagnets 2211 are fixedly installed on the upper surface of the junction box 2120, and each second electromagnet 2211 contacts 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, and the first electromagnet 2210 is turned on, so that the iron block 2209 moves upward under the action of magnetism, so that the iron block 2209 contacts the first electromagnet 2210, and the iron block 2209 is moved upward under the action of magnetism. A windproof unit 22 is provided, so that 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 contacts the upper surface of the coal. When the height of the coal does not exceed the height of the carriage, the bottom surface of the windproof shell 2204 contacts the upper surface of the carriage, thereby reducing the influence of the wind force on the spraying trajectory of the dust suppressant, thereby increasing the windproof effect of the nozzle 15, preventing the dust suppressant from deviating from the predetermined trajectory during spraying, and further ensuring the uniform spraying effect of the device in windy weather;

[0043] A slider 2212 is fixedly installed on the side of the two iron blocks 2209 that are close to each other. Two slide grooves 2213 are formed on the inner wall of the L-shaped plate 2205. The two sliders 2212 are slidably connected inside the slide grooves 2213. The shape of the slider 2212 is T-shaped, and the shape of the slide groove 2213 matches the shape of the slider 2212. The installation of the slider 2212 and the slide groove 2213 plays a role in limiting the movement trajectory of the iron block 2209, thereby preventing the iron block 2209 from deviating from the movement trajectory during movement, thereby ensuring the stability of the movement of the iron block 2209;

[0044] Two groups of telescopic columns 2214 are fixedly installed on the outer surface of each connecting plate 2109, and 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 fixed spring 2110 and the second fixed spring 2201, and 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 serves to limit the moving trajectories of the first moving block 2111 and the second moving block 2202, thereby ensuring the stability of the movement of the first moving block 2111 and the second moving block 2202.

[0045] The specific implementation of this embodiment is as follows: when the moving seat 2105 moves, the touch plate 2121 squeezes the second moving block 2202, and the second moving block 2202 triggers 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, so that the first electromagnet 2210 adsorbs the iron block 2209, thereby driving the iron block 2209 to move upward under the action of magnetism, and then under the action of gravity of the windproof shell 2204, the iron block 2209 is pulled upward. The windproof shell 2204 slides downward, thereby having a windproof effect on the nozzle 15. After the dust suppressant is sprayed, the controller inside the rocker arm body 2101 disconnects the power supply of the first electromagnet 2210 and turns on the power supply of the second electromagnet 2211, so that the iron block 2209 moves downward under the action of its own gravity and the magnetic adsorption of the second electromagnet 2211, and then the iron block 2209 pulls the traction rope 2208 to pull up the windproof shell 2204, so as to prevent the windproof shell 2204 from affecting the spraying range of the dust suppressant.

The installation of the slide plate 317 and the slide rail 318 serves to limit the movement trajectory of the rack plate 308, thereby preventing the rack plate 308 from deviating from the movement trajectory during movement, thereby ensuring the stability of the movement of the rack plate 308.

[0051] A connecting bearing 319 is fixedly installed on the upper end of the connecting gear 310. The connecting bearing 319 is sleeved on the rotating shaft 309. The top end of the connecting bearing 319 is rotatably connected to the inner top wall of the moving box 304. The installation of the connecting bearing 319 stabilizes the connecting gear 310, thereby avoiding the connecting gear 310 from shaking during rotation, thereby ensuring the stability of the rotation of the connecting gear 310.

[0052] The specific implementation of this embodiment is as follows: when the adjustment unit 21 detects strong winds, 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 is facing downward, when the pressing plate 305 contacts the third touch switch 306 during the upward movement, 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 to the side away from the electric push rod 307, so that the rack plate 308 drives the connecting gear 310 to rotate. The second conical wheel 313 is rotated, so that the second conical wheel 313 drives the two-way ball screw 312 connected thereto to rotate, and the two-way ball screw 312 drives the two movable plates 314 to move toward one side close to each other, so that the movable plates 314 cooperate with the clamping blocks 315 to clamp and fix the rocker arm body 2101, avoiding violent shaking of the rocker arm body 2101 in windy weather, thereby preventing the dust suppressant from deviating from the predetermined spraying trajectory and ensuring the uniform spraying effect of the device.
