Description

Technical Field

[0001] This invention belongs to the field of train cleaning devices, and particularly relates to a mechanically synchronized flushing device that follows the connection between train carriages. Background Technology

[0002] After loading materials (such as various mineral powders and coal) into the loading towers of port railway carriages, material debris will scatter at the carriage joints, couplers, and carriage edges. This debris may pose a safety hazard during train operation, and the railway department requires it to be thoroughly cleaned before being loaded onto the railway for shipment. Currently, cleaning is entirely done manually, resulting in a poor working environment, heavy workload, high risk, and significant dust levels, which is also detrimental to worker health, posing numerous potential safety hazards. Summary of the Invention

[0003] The purpose of this invention is to provide a mechanically synchronized washing device for the connection of train carriages, in order to solve the above-mentioned technical problems.

[0004] To solve the above-mentioned technical problems, the specific technical solution of the washing device for the mechanical synchronous following train carriage connection of the present invention is as follows:

[0005] A mechanically synchronized flushing device for the connection of train carriages includes a cantilever, which is long and parallel to the direction of train movement, located above the train carriages. One end of the cantilever is mounted on a cleaning device, and the other end is suspended. A slide rail is fixedly mounted on the cantilever, and a spring-loaded mechanism is vertically mounted on the slide rail via a slider. A water spraying device is fixedly mounted on the spring-loaded mechanism. When the train moves forward, the rear inner wall of the carriage contacts the bottom end of the spring-loaded mechanism, pushing it to slide along the slide rail. At this time, the water spraying device is aimed at the connection at the rear of the carriage, simultaneously cleaning the connection of the train carriages. The upper surface of the cantilever has a spring-loaded triggering mechanism, which is used to trigger the spring-loaded mechanism to spring up and reset, completing the cleaning cycle.

[0006] Furthermore, the slide rail has limiting blocks at both ends to limit the movement distance of the pop-up mechanism.

[0007] Furthermore, it includes a proximity switch, which is installed on the upper surface of the cantilever. A sensing plate is fixedly connected to the slider. In the initial state, the pop-up mechanism is at the leftmost end of the slide rail. The sensing plate is in contact with the proximity switch. When the carriage pushes the pop-up mechanism forward together, the sensing plate of the proximity switch leaves the proximity switch. After program judgment, the water valve is opened, and the water spray device enters water to achieve the washing of the carriage connection.

[0008] Furthermore, it includes a tension balancer, which is fixedly installed at the end of the cantilever. The steel wire rope of the tension balancer is connected to the lifting mechanism. When the lifting mechanism is lifted and detached from the train car, the tension balancer pulls the lifting mechanism back to its original position, thus completing one cycle.

[0009] Furthermore, the pop-up mechanism includes a pop-up component, a bending component, and a contact roller. The pop-up component is fixedly connected to the slider, the bending component is fixed at the lower end of the pop-up component, and the contact roller is fixed at the lower end of the bending component. When the train moves forward, the carriage contacts the contact roller, and the pop-up component moves forward along the slide rail with the carriage. When the train reverses and touches the contact roller, the bending component bends to prevent the train from damaging the washing device.

[0010] Furthermore, the spring-loaded component includes a shaft, a bushing, a bearing, a spring, a C-pin, and a locking component. The upper end of the bushing is fixed to the slider. The shaft passes through the bushing, with its upper end protruding above the upper surface of the cantilever and connected to the bearing. Its lower end protrudes from the bushing and is fixedly connected to the bending component. The upper end of the shaft has a step, and the bushing also has a step inside. A spring is located between the steps. The side wall of the bushing has a vertical groove. When the shaft is fitted into the bushing, the C-pin is driven into the shaft, and the shaft slides up and down along the groove inside the bushing. The lower end of the shaft has a groove, and the side wall of the bushing has a through hole. A locking component is located in the through hole to lock the shaft in the initial state. In the initial state, the spring is in a compressed state. When the shaft is subjected to an upward force, the locking component unlocks, and the shaft quickly springs upward under the action of the spring force, causing the contact roller to disengage from the carriage.

[0011] Furthermore, the locking component includes a threaded tube, a steel ball, a second spring, and a set screw and nut. The steel ball is placed inside the through hole, and the threaded tube is placed outside the through hole. The second spring is placed inside the threaded tube by the set screw and nut, and presses the steel ball. In the initial state, the first spring is in a compressed state. Due to the force of the second spring, the steel ball is always stuck to the shaft through the groove, preventing the shaft from springing upward. When the shaft is subjected to an upward force, it breaks free from the restriction of the steel ball, and the first spring quickly springs the shaft upward. The steel ball rolls along the shaft inside the bushing. When the shaft encounters a force that presses it down to the bottom, the shaft is again stuck by the steel ball, returning to the initial state and maintaining it.

[0012] Furthermore, the water spraying device is mounted on the bushing and includes a cross-shaped fixing clamp, a water pipe connector, a rear fixing clamp, a second bearing, and a water spray rod. The cross-shaped fixing clamp fixes the water pipe connector to the bushing. The water spray rod is installed at the front end of the water pipe connector, and a water hose is connected to the rear end of the water pipe connector. The rear fixing clamp is installed at the rear end of the water pipe connector, and the second bearing is installed at both ends of the rear fixing clamp. The second bearing contacts the lower surface of the cantilever. When the water spraying device moves forward with the pop-up component, the second bearing at the end slides along the lower surface of the cantilever, providing support for the water spraying device.

[0013] Furthermore, the bending component includes a connecting sleeve, a lower axle sleeve, and a fixing sleeve. The connecting sleeve is fixedly connected to the lower end of the shaft by a fixing screw. The lower end of the connecting sleeve has a notch on one side, with the notch facing the direction of train reversal. The lower axle sleeve is movably connected to the lower end of the connecting sleeve by a pin. The upper end of the contact roller has a connecting rod. The connecting rod is sleeved inside the lower axle sleeve and fixedly connected to the lower end of the lower axle sleeve by the fixing sleeve. The extension length of the connecting rod is freely adjustable. When the train reverses, the lower axle sleeve swings backward, and the contact roller bends to prevent collision with the carriage.

[0014] Furthermore, the pop-up triggering mechanism includes an upper pop-up inclined surface and a lower pressing inclined surface, which are fixed to the upper surface of the cantilever. The lower pressing inclined surface is located at the left end of the slide rail, and the lower pressing inclined surface is located at the right end of the slide rail. Both the upper pop-up inclined surface and the lower pressing inclined surface are sloping platforms. When the pop-up mechanism moves along the slide rail and reaches the upper pop-up inclined surface on the cantilever, the bearing in the pop-up mechanism is axially popped up and detached from the train car. At this time, the tension balancer pulls the pop-up mechanism back. When the pop-up mechanism enters the bottom of the lower pressing inclined surface, the shaft is pressed down and reset. When the next car passes by, the contact roller contacts the car and continues to push the pop-up mechanism forward. At the same time, the water spraying device sprays water to clean it, and the above actions are repeated in a cycle.

[0015] The mechanically synchronized washing device for the connection of train carriages of the present invention has the following advantages: The washing device of the present invention has contact rollers and slide rails, which can synchronize with the movement of train carriages and automatically clean the connection of carriages. It is equipped with a pop-up mechanism and a pop-up trigger mechanism, which automatically pops up and resets, realizing the automatic cleaning of each connection in a cycle. It is also equipped with a bending component, which can fold up the contact rollers when the train reverses or encounters obstacles to prevent damage to the washing device. The device of the present invention can realize automatic cleaning by synchronizedly following the train. The height and elasticity are adjustable, the adaptability is high, the cleaning efficiency is improved, the manpower is reduced, and the safety hazards of manual cleaning are avoided.

[0029] To better understand the purpose, structure, and function of this invention, the following detailed description of a mechanically synchronized washing device for the connection of train carriages is provided in conjunction with the accompanying drawings.

[0030] like Figure 1 As shown, the present invention provides a mechanically synchronized flushing device 3 for the connection between train carriages. This device, along with a cleaning device 2, is fixedly connected to a bracket 1 on one side of the train track. It can be used in conjunction with the cleaning device 2. The carriage top is open, and the flushing device 3 is used to flush the connection between the carriages. The present invention uses a left-to-right train travel direction to describe the structure of the flushing device.

[0031] like Figure 2 As shown, the flushing device 3 includes a cantilever 31, a pop-up mechanism 32, a slide rail 33, a slider 37, a tension balancer 34, a proximity switch 35, a pop-up trigger mechanism 36, and a water spray device 38. The cantilever 31 is elongated and located above the train car, parallel to the direction of train movement. One end of the cantilever 31 is mounted on the cleaning device 2, and the other end is suspended. A slide rail 33 is fixedly mounted on the cantilever 31. The pop-up mechanism 32 is vertically mounted on the slide rail 33 via the slider 37. The pop-up mechanism 32 has a water spray device 38 that moves with it. During train movement, the rear inner wall of the car contacts the bottom of the pop-up mechanism 32, pushing it to slide along the slide rail 33. At this time, the water spray device 38 is aimed at the connection point at the rear of the car, simultaneously cleaning the connection point. Limiting blocks 331 are located at both ends of the slide rail 33 to limit the movement distance of the pop-up mechanism 32. The tension balancer 34 is fixedly installed at the end of the cantilever 31. The tension balancer 24 is a mature product on the market. The front wire rope is retractable and automatically retracts when no external force is applied, functioning similarly to a spring, but with a much longer extension stroke. The wire rope of the tension balancer 34 is connected to the pop-up mechanism. When the pop-up mechanism pops up and detaches from the train car, it can pull the pop-up mechanism 32 back to its original position, completing one cycle. The upper surface of the cantilever 31 has a pop-up trigger mechanism 36, which is used to trigger the pop-up mechanism 32 to pop up and reset. The proximity switch 35 is installed on the upper surface of the cantilever 31. The sensing plate 351 of the proximity switch 35 is fixedly connected to the slider 37. In the initial state, the pop-up mechanism 32 is at the leftmost end of the slide rail, and the sensing plate 351 is in contact with the proximity switch 35. When the train car pushes the pop-up mechanism 32 forward together, the sensing plate 351 of the proximity switch 35 moves away from the proximity switch 35. After program judgment, the water valve is opened, and the water spray device 38 enters, realizing the washing of the connection between the train cars.

[0032] like Figure 3As shown, the pop-up mechanism 32 includes a pop-up component 321, a bending component 322, and a contact roller 323. The pop-up component 321 is fixedly connected to the slider 37, the bending component 322 is fixed to the lower end of the pop-up component 321, and the contact roller 323 is fixed to the lower end of the bending component 322. When the train moves forward, the carriage contacts the contact roller 323. The contact roller 323 can reduce friction. The pop-up component 321 moves forward along the slide rail 33 with the carriage. When the train reverses and touches the contact roller 323, the bending component 322 bends to prevent the train from damaging the washing device.

[0033] like Figure 4 Figure 5 As shown, the spring-loaded component 321 includes a shaft 3211, a bushing 3212, a bearing 3215, a spring 3216, a C-pin 3217, and a locking component 3218. The upper end of the bushing 3212 is locked and fixed to the slider 37 by a locking sleeve 3213 and a locking nut 3214. The shaft 3211 passes through the bushing 3212, with its upper end protruding above the upper surface of the cantilever 31 and connected to the bearing 3215, and its lower end protruding from the bushing 3212 and fixedly connected to the bending component 322. Figure 5 As shown, there is a step at the upper end of the shaft 3211 and a step inside the bushing 3212. A spring 3216 is located between the steps. The side wall of the bushing 3212 has a vertical groove 32121. When the shaft 3211 is fitted into the bushing 3212, a C-pin 3217 is driven into the shaft 3211. The shaft 3211 can then slide up and down along the groove 32121 inside the bushing 3212. The C-pin 3217 acts as a limit to prevent the shaft 3211 from running out of the bushing 3212. The lower end of the shaft 3211 has a groove 32111, and the side wall of the bushing 3212 has a through hole 32122. A locking component 3218 is located within the through hole 32122 to lock the shaft 3211 in the initial state. The locking component 3218 includes a threaded tube 32181, a steel ball 32182, a second spring 32183, and a set screw and nut 32184. The steel ball 32182 is placed inside the through hole 32122, the threaded tube 32181 is located outside the through hole 32122, and the second spring 32183 is located inside the threaded tube 32181 via the set screw and nut 32184, pressing against the steel ball 32182. In the initial state, the first spring 3216 is in a compressed state. Due to the force of the second spring 32183, the steel ball 32182 is always held in place by the groove 32111, preventing the shaft 3211 from springing upwards. The state at this time is as follows: Figure 3 As shown. When shaft 3211 is subjected to an upward force, it can break free from the restraint of steel ball 32182. The spring 3216 then quickly springs shaft 3211 upward, and steel ball 32182 rolls along shaft 3211 inside bushing 3212, as shown. Figure 6 Figure 7As shown. When shaft 3211 is subjected to force and pressed down to the bottom, shaft 3211 is then caught by steel ball 32182, returning to its initial state and maintaining it. In this mechanism, the force that springs shaft 3211 upward is adjustable. Spring 32183 is limited by set screw nut 32184. The spring force can be changed by adjusting the compression length of spring 32183 through set screw nut 32184, thereby changing the spring force, and thus changing the force and speed at which shaft 3211 springs up.

[0034] like Figure 3 As shown, the water spray device 38 is mounted on the bushing 3212 and includes a cross-shaped fixing clamp 381, a water pipe connector 382, ​​a rear fixing clamp 383, a second bearing 384, and a water spray rod 385. The cross-shaped fixing clamp 381 fixes the water pipe connector 382 to the bushing 3212. The water spray rod 385 is installed at the front end of the water pipe connector 382, ​​and a water hose is connected to the rear end of the water pipe connector 382. The rear fixing clamp 383 is installed at the rear end of the water pipe connector 382, ​​and the second bearing 384 is installed at both ends of the rear fixing clamp 383. The second bearing 384 contacts the lower surface of the cantilever. When the water spray device 38 moves forward with the pop-up component 321, the second bearing 384 at the end slides along the lower surface of the cantilever 31, providing support for the water spray device 38 and making it more stable during the rinsing process. Figure 8 As shown.

[0035] like Figure 3 As shown, the bending component 322 includes a connecting sleeve 3221, a lower axle sleeve 3222, and a fixing sleeve 3223. The connecting sleeve 3221 is fixedly connected to the lower end of the shaft 3211 by a fixing screw 3224. The lower end of the connecting sleeve 3221 has a notch 32211 on one side, facing the direction of train reversal. The lower axle sleeve 3222 is movably connected to the lower end of the connecting sleeve 3221 by a pin 3225, allowing the lower axle sleeve 3222 to rotate along the notch. The upper end of the contact roller 323 has a connecting rod 3231, which is fitted inside the lower axle sleeve 3222 and fixedly connected to the lower end of the lower axle sleeve 3222 by the fixing sleeve 3223. The extension length of the connecting rod 3231 is freely adjustable to accommodate carriages of different heights. When the train reverses or encounters other obstacles, the lower axle sleeve 3222 swings backward, bending the contact roller 323 to prevent collision with the carriage, as shown below. Figure 9 As shown.

[0036] like Figure 2As shown, the pop-up triggering mechanism 36 includes an upper pop-up inclined surface 361 and a lower pressing inclined surface 362. The upper pop-up inclined surface 361 and the lower pressing inclined surface 362 are fixed to the upper surface of the cantilever 31. The lower pressing inclined surface 362 is located at the left end of the slide rail 33 and at the right end of the slide rail 33. Both the upper pop-up inclined surface 361 and the lower pressing inclined surface 362 are sloping platforms. When the pop-up mechanism 32 moves along the slide rail 33 to the upper pop-up inclined surface on the cantilever 31, the bearing 32 in the pop-up mechanism 32... 15 will lift the shaft 3211 upwards, detaching from the train car. The lifting mechanism 32 will no longer be pushed by the car. At this time, the tension balancer 34 will pull the lifting mechanism 32 back. When the lifting mechanism 32 enters the bottom of the downward slope, the shaft 3211 will be pressed down and reset. When the next car passes by, the contact roller 323 will contact the car and continue to push the lifting mechanism 21 forward. At the same time, the water spraying device 38 sprays water to clean it. The above actions are repeated in a cycle.

[0037] The initial state of the flushing device is as follows Figure 10 As shown, when the carriage pushes forward to contact the roller 323, the entire pop-up mechanism 32 moves forward along the slide rail 33. At the same time, the pop-up mechanism 32 maintains its initial state, the sensor plate 351 moves away from the proximity switch 35, and the proximity switch 35 receives a signal, the water valve opens, and the water spray device 38 enters to wash the carriage. At this time, the water spray device 38 can realize synchronous and continuous washing of the relative carriage connection.

[0038] When the bearing at the top of the spring-loaded mechanism 32 touches the upward-springing inclined surface 361, as Figure 11 As shown, the upward-sloping surface 361 applies an upward force to the shaft 3211 of the lifting mechanism 32, causing the shaft 3211 to disengage from the locking of the steel ball 32182. The shaft 3211 then quickly springs upward, disengaging the contact roller 323 from the carriage control, as follows. Figure 11 The tension balancer 34 quickly pulls the pop-up mechanism 32 back.

[0039] When the pop-up mechanism 32 is pulled into the downward pressure slope 362, as Figure 12 As shown, the tension balancer 34 pulls back while pressing down the inclined plane 362, pressing down the shaft 3211. When the pop-up mechanism 32 hits the limit block 331, the steel ball 32182 locks the shaft 3211, and the pop-up mechanism 32 returns to its initial position. The proximity switch 35 also senses the sensing plate 351, the water valve closes, and the water pipe stops rinsing, completing one cycle of rinsing.

When the shaft (3211) is subjected to an upward force, it breaks free from the restriction of the steel ball (32182) and is quickly lifted upward by the action of spring one (3216). The steel ball (32182) rolls along the shaft (3211) inside the bushing (3212). When the shaft (3211) is subjected to a force that presses it down to the bottom, the shaft (3211) is again held in place by the steel ball (32182), returning to its initial state and maintaining it.

5. The rinsing device according to claim 3, characterized in that, The water spray device (38) is mounted on the bushing (3212) and includes a cross clamp (381), a water pipe connector (382), a rear clamp (383), a bearing (384), and a water spray rod (385). The cross clamp (381) fixes the water pipe connector (382) to the bushing (3212). The water pipe connector (382) has a water spray rod (385) installed at the front end and a water hose connected to the rear end. The rear clamp (383) is installed at the rear end of the water pipe connector (382). The bearing (384) is installed at both ends of the rear clamp (383). The bearing (384) contacts the lower surface of the cantilever (31). When the water spray device (38) moves forward with the pop-up component (321), the bearing (384) at the end slides along the lower surface of the cantilever (31) to support the water spray device (38).

6. The rinsing device according to claim 1, characterized in that, The bending component (322) includes a connecting sleeve (3221), a lower shaft sleeve (3222), and a fixing sleeve (3223). The connecting sleeve (3221) is fixedly connected to the lower end of the shaft (3211) by a fixing screw (3224). The lower end of the connecting sleeve (3221) has a notch (32211) on one side, and the notch (32211) faces the direction of train retraction. The lower shaft sleeve (3222) is connected to the connecting sleeve (3221) by a pin (3225). 221) The lower end is movably connected. The upper end of the contact roller (323) has a connecting rod (3231). The connecting rod (3231) is sleeved in the lower axle sleeve (3222) and fixedly connected to the lower end of the lower axle sleeve (3222) through the fixing sleeve (3223). The extension length of the connecting rod (3231) can be freely adjusted. When the train moves backward, the lower axle sleeve (3222) swings backward and the contact roller (323) bends to prevent collision with the carriage.

7. The rinsing device according to claim 3, characterized in that, The pop-up triggering mechanism (36) includes an upper pop-up inclined surface (361) and a lower pressing inclined surface (362). The upper pop-up inclined surface (361) and the lower pressing inclined surface (362) are fixed on the upper surface of the cantilever (31). The lower pressing inclined surface (362) is located at the left end of the slide rail (33) and at the right end of the slide rail (33). Both the upper pop-up inclined surface (361) and the lower pressing inclined surface (362) are sloping platforms. When the pop-up mechanism (32) moves along the slide rail (33) to the upper pop-up inclined surface on the cantilever (31), the mechanism will trigger the mechanism to ... When the train car passes by, the bearing 1 (3215) in the spring mechanism (32) lifts the shaft (3211) upward and separates it from the train car. At this time, the tension balancer (34) pulls the spring mechanism (32) back. When the spring mechanism (32) enters the bottom of the downward slope (362), the shaft (3211) is pressed down and reset. When the next car passes by, the contact roller (323) contacts the car and continues to push the spring mechanism (21) forward. At the same time, the water spraying device (38) sprays water to clean it. The above actions are repeated in a cycle.
