Description

Technical Field

[0001] This utility model relates to the field of tippler technology, specifically a tippler track alignment device. Background Technology

[0002] A railway tippler is a mechanized unloading device specifically designed for railway freight transport. Its main function is to tip over railway freight cars loaded with bulk goods such as coal, ore, grain, and chemical raw materials, allowing the goods to be dumped out through openings at the bottom or side of the car, thus achieving efficient and automated unloading operations.

[0003] During the operation of railway tipplers, the transfer platform needs to run back and forth between the loaded and empty tracks to transfer loaded and empty cars. The precise alignment of the loaded and empty tracks directly affects the normal operation and safety of the transfer platform. If the two tracks are not accurately aligned, the tracks will not align when the transfer platform performs the alignment pin operation, easily leading to derailment accidents. This not only damages the equipment but may also cause serious safety problems, affecting the production efficiency and safety of the railway tippler. Currently, alignment operations are often performed by operators manually controlling the transfer platform through on-site observation or camera monitoring until the tracks are visually aligned before inserting the pin. This relies on human experience and has low alignment accuracy. Therefore, we propose a new type of tippler track alignment device that can improve alignment accuracy and avoid derailment accidents. Utility Model Content

[0004] The purpose of this invention is to provide a tippler track alignment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tipper track alignment device, comprising a fixed base, one end of which is uniformly provided with limit grooves, a limit slider is slidably connected inside the limit groove, a connecting frame is fixed between adjacent limit sliders, an oil storage tank is installed on the top of the connecting frame, an oil distribution pipe assembly is provided between the oil storage tank and the limit slider, a ball bearing is uniformly movably connected to one end of the limit slider near the limit groove, a primary alignment housing is fixed to one end of the connecting frame, an intelligent identification positioning box is embedded in the primary alignment housing, a laser positioning sensor is installed at the middle position of the intelligent identification positioning box, radio frequency identification positioning sensors are installed on both sides of the intelligent identification positioning box, a secondary alignment housing is installed at the top inside the fixed base, a motor is installed at one end of the secondary alignment housing, a worm gear is connected to the output end of the motor, a worm wheel meshes on the worm gear, a lead screw is fixed at the middle position of the worm wheel, and a nut seat connected to the primary alignment housing is screwed onto the lead screw.

[0006] Preferably, there are two of each of the fixed base, the primary alignment housing, and the secondary alignment housing, and screw holes are evenly distributed at the bottom edge of the fixed base.

[0007] Preferably, the top of the oil storage tank is threaded with a sealing plug, and the bottom of the oil storage tank is connected to the top of the oil distribution pipe assembly.

[0008] Preferably, a miniature air pump is installed at the top of the interior of the intelligent identification and positioning box, and the output end of the miniature air pump is equipped with a dust blowing pipe that matches the laser positioning sensor.

[0009] Preferably, a drive arm is fixed between the housing and the nut seat for primary alignment.

[0010] Preferably, a return spring is evenly installed between one side of the drive arm and the fixed base using screws.

[0011] Preferably, the lead screw, worm gear, and worm wheel are each provided with a rotary bearing between themselves and the housing for secondary alignment.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The tippler track alignment device optimizes its performance by installing worm gears, etc. On the one hand, the two fixed bases are firmly installed on the ground at the ends of the loaded and unloaded tracks by screws. Subsequently, the sliding guide effect between the limiting groove on the fixed base and the limiting slider on the primary alignment housing helps to ensure the accuracy of subsequent track alignment. Specifically, when track alignment is required, the transfer platform is started, and the primary alignment housing is pushed to slide along the limiting groove until the laser positioning sensor on the intelligent identification positioning box embedded in the two primary alignment housings completes the initial laser positioning identification function. At this time, the loaded and unloaded tracks can be initially aligned. Then, the transfer platform is stopped by the external control equipment. On the other hand, the external control equipment of the device After coarse positioning is completed, the motor is started. With the help of the two-stage transmission consisting of worm gear, worm wheel, lead screw and nut seat, the drive arm on the secondary alignment housing fixed inside the fixed base can be automatically, uniformly and smoothly slid and adjusted. At the same time, based on the self-locking effect of the worm wheel reverse drive rod, the stability of the drive arm is ensured and it will not deviate arbitrarily. This is beneficial for the secondary automatic calibration of the tracks of loaded and empty lines. It is also beneficial for the two sets of radio frequency identification positioning sensors and corresponding RFID tags installed on the intelligent identification positioning boxes embedded in the two primary alignment housings to identify and position the tracks. Through the radio frequency identification feedback function and high-precision automatic drive function, it is beneficial to achieve high-precision alignment adjustment with small displacement. After the two tracks are aligned, the alignment pin of the transfer platform is inserted to ensure track overlap and avoid derailment accidents.

[0014] (2) The tippler track alignment device is equipped with radio frequency identification positioning sensors, etc. When the device is in operation, the micro air pump on the intelligent identification positioning box is started, and the dust blowing pipe can continuously blow dust to clean and protect the laser positioning sensor, so as to avoid dust and debris from obstructing the laser positioning effect. Moreover, by installing a set of laser positioning sensors and two sets of radio frequency identification positioning sensors on the device to form a horizontal three-point positioning mechanism, the track positioning and identification accuracy is improved compared with simple photoelectric positioning or camera shooting positioning, thus improving the tippler track alignment effect.

[0015] (3) The tilting machine track alignment device optimizes its structure by installing an oil storage tank. With the oil storage tank vertically installed on the top of the connecting frame, the lubricating oil inside the oil storage tank will be evenly introduced into the limiting slider and penetrate the surface of the ball under the action of gravity through the oil distribution pipe group. Subsequently, during the alignment adjustment, the machine housing moves based on the sliding guide action of the limiting slider and the limiting groove. Through the rolling action of the ball and the continuous lubrication effect of the lubricating oil, the friction effect during the alignment drive is reduced, the smoothness of the track alignment adjustment is improved, and it is easy to promote.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-5 An embodiment of this utility model provides a tippler track alignment device, including a fixed base 2, a limiting groove 7 evenly provided at one end of the fixed base 2, a limiting slider 11 slidably connected inside the limiting groove 7, a connecting frame 9 fixed between adjacent limiting sliders 11, an oil storage tank 4 installed on the top of the connecting frame 9, an oil distribution pipe group 8 provided between the oil storage tank 4 and the limiting slider 11, and a ball bearing 12 evenly movably connected to one end of the limiting slider 11 near the limiting groove 7;

[0024] One end of the connecting frame 9 is fixed with a primary alignment housing 6. A smart identification and positioning box 5 is embedded in the primary alignment housing 6. A laser positioning sensor 21 is installed in the middle of the smart identification and positioning box 5. Radio frequency identification and positioning sensors 20 are installed on the smart identification and positioning boxes 5 on both sides of the laser positioning sensor 21.

[0025] Two fixed bases 2, two primary alignment housings 6 and two secondary alignment housings 1 are provided. Screw holes are evenly provided at the bottom edge of the fixed base 2.

[0026] In use, the two fixed bases 2 are firmly installed on the ground at the ends of the loaded and unloaded tracks respectively with screws. The sliding guide effect between the limiting groove 7 on the fixed base 2 and the limiting slider 11 on the primary alignment housing 6 helps to ensure the accuracy of the subsequent track alignment. Specifically, when the track alignment operation is required, the transfer platform is started, and the primary alignment housing 6 is pushed to slide along the limiting groove 7 until the laser positioning sensor 21 on the intelligent identification and positioning box 5 embedded in the two primary alignment housings 6 completes the preliminary laser positioning and identification function. At this time, the tracks of the loaded and unloaded tracks can be initially aligned. Then, the transfer platform is stopped by using external control equipment.

[0027] The top of the fixed base 2 is equipped with a secondary alignment housing 1. A motor 13 is installed at one end of the secondary alignment housing 1. The output end of the motor 13 is connected to a worm gear 16. A worm wheel 17 is meshed on the worm gear 16. A lead screw 14 is fixed at the middle position of the worm wheel 17. A nut seat 15 that is connected to the primary alignment housing 6 is screwed onto the lead screw 14.

[0028] A drive arm 10 is fixed between the housing 6 and the nut seat 15 for one-time alignment;

[0029] A return spring 3 is evenly installed between one side of the drive arm 10 and the fixed base 2 by screws;

[0030] The lead screw 14, worm 16 and worm wheel 17 are respectively provided with rotary bearings between them and the secondary alignment housing 1;

[0031] During use, the external control equipment will start the motor 13 after coarse positioning is completed. In conjunction with the two-stage transmission action formed by the worm 16, worm wheel 17, lead screw 14 and nut seat 15, the drive arm 10 fixed on the secondary alignment housing 1 inside the fixed base 2 can be automatically, uniformly and smoothly slid and adjusted. At the same time, based on the self-locking effect of the worm wheel 17 driving the worm 16 in the opposite direction, the stability of the drive arm 10 is ensured and it will not deviate arbitrarily. This is beneficial for the secondary automatic calibration of the tracks of the loaded and empty tracks. It is also beneficial for the two sets of radio frequency identification positioning sensors 20 and corresponding RFID tags installed on the intelligent identification positioning boxes 5 embedded on the two primary alignment housings 6 to identify and position the tracks. Through the radio frequency identification feedback function and the high-precision automatic drive function, it is beneficial to achieve high-precision alignment adjustment with small displacement. After the two tracks are aligned, the alignment pin of the transfer platform is allowed to ensure track overlap and avoid derailment accidents.

[0032] The top of the oil storage tank 4 is threaded with a sealing plug, and the bottom of the oil storage tank 4 is connected to the top of the oil distribution pipe assembly 8.

[0033] The top of the intelligent identification and positioning box 5 is equipped with a miniature air pump 18, and the output end of the miniature air pump 18 is equipped with a dust blowing pipe 19 that matches the laser positioning sensor 21.

[0034] When in use, the micro air pump 18 on the intelligent identification and positioning box 5 is started, and the dust blowing pipe 19 continuously blows dust to clean and protect the laser positioning sensor 21, so as to avoid dust and debris from obstructing the laser positioning effect. Moreover, by installing a set of laser positioning sensors 21 and two sets of radio frequency identification positioning sensors 20 on the device to form a horizontal three-point positioning mechanism, the track positioning and recognition accuracy is improved compared with simple photoelectric positioning or camera shooting positioning, and the track alignment effect of the tippler is improved.

[0035] In this embodiment, when in use: An external power supply is connected. First, the user securely installs two fixed bases 2 onto the ground at the ends of the loaded and unloaded tracks using screws. Then, the sliding guide effect between the limiting groove 7 on the fixed base 2 and the limiting slider 11 on the primary alignment housing 6 helps ensure the accuracy of subsequent track alignment. Specifically, when track alignment is required, the moving platform is started, pushing the primary alignment housing 6 to slide along the limiting groove 7 until the laser positioning sensor 21 on the intelligent identification and positioning box 5 embedded in the two primary alignment housings 6 completes the initial laser positioning and identification function. At this point, the loaded and unloaded tracks can be aligned. After initial alignment, the external control equipment stops the movement of the transfer platform. Simultaneously, after coarse positioning, the external control equipment starts motor 13. This, combined with the two-stage transmission of worm gear 16, worm wheel 17, lead screw 14, and nut seat 15, automatically and smoothly adjusts the drive arm 10, which is fixed inside the fixed base 2 and mounted on the secondary alignment housing 1. The self-locking effect of the worm wheel 17 driving the worm gear 16 in the reverse direction ensures the stability of the drive arm 10, preventing it from shifting arbitrarily. This facilitates the secondary automated calibration of the tracks on both loaded and unloaded lines and benefits the intelligent recognition and positioning systems embedded in the two primary alignment housings 6. Two sets of RFID positioning sensors 20 installed on box 5 are used for identification and positioning with corresponding RFID tags. Through RFID feedback function and high-precision automated drive function, it is beneficial to achieve high-precision alignment adjustment with small displacement. After the two tracks are aligned, the alignment pin of the transfer platform is inserted to ensure track overlap and avoid derailment accidents. In addition, the micro air pump 18 on the intelligent identification and positioning box 5 is started, and the laser positioning sensor 21 is continuously cleaned and protected by the dust blowing pipe 19 to prevent dust from adhering and causing obstruction, which would affect the laser positioning effect. The horizontal three-point system formed by installing one set of laser positioning sensor 21 and two sets of RFID positioning sensors 20 on the device is also effective. Compared to simple photoelectric positioning or camera-based positioning, the positioning mechanism improves the accuracy of track positioning and recognition, and enhances the alignment effect of the tipper track. In addition, by vertically installing an oil tank 4 on the top of the connecting frame 9, the lubricating oil inside the oil tank 4 will be evenly introduced into the limiting slider 11 and penetrate the surface of the ball bearings 12 under the action of gravity through the oil distribution pipe group 8. Subsequently, during the alignment adjustment, the entire process of the machine housing 6 moving based on the sliding guide action formed by the limiting slider 11 and the limiting groove 7 is reduced by the rolling action of the ball bearings 12 and the continuous lubrication effect of the lubricating oil, thus improving the smoothness of track alignment adjustment and facilitating its promotion.
