Description

Technical Field

[0001] The invention relates to the technical field of railway construction, and in particular to a railway track temperature control system. Background Art

[0002] With the rapid development of my country's railways, the mileage of railways is getting longer and longer. It is often necessary to carry out daily maintenance or renovation of the operating lines, and the construction volume of operating line railway projects is increasing year by year. During construction in high temperature seasons, high temperatures will cause the temperature of the rails to rise. If the rails are not cooled in time, the existing state of the railway track bed will be destroyed during construction, and the lateral resistance of the track bed will be reduced. When the rail temperature is higher than the rail locking temperature, the seamless line rails are easily deformed and expanded due to temperature stress, resulting in lateral displacement of the line, causing train overturning accidents, and seriously threatening the safety of railway driving. Therefore, it is of great significance to take timely and effective cooling treatment of the rails.

[0003] The invention with announcement number CN208055775U provides a rail cooling device, including water pipes and sponge strips arranged on both sides of the rail waist, the water pipes are located above the sponge strips, and also include a temperature detector and a controller arranged on the rail, a water tank and a water pump arranged on the outside of the rail; a number of spray holes are evenly opened on the water pipe, the water tank is connected to the water pump, and the water pump is connected to the water pipe; the temperature detector is connected to the controller, and the water pump is connected to the signal output end of the controller.

[0004] The existing rail cooling device has a simple structure and can only be fixedly installed on both sides of the rail. After the construction is completed, the water pipe needs to be removed from the rail before it can be used again, which is very inconvenient. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a railway track temperature control system, in which water pipes can be moved on the rails to facilitate cooling of rails at different positions, and the use is very convenient.

[0006] The above-mentioned inventive object of the present invention is achieved through the following technical scheme: a railway track temperature control system, comprising a water pipe arranged parallel to the rail, the water pipe is provided with a nozzle facing the rail, and also comprises a water tank connected to the water pipe, the water tank is connected to a water pump for supplying water to the water pipe, and also comprises a base plate placed on the rail, the bottom of the base plate is rotatably connected to an I-shaped wheel capable of rolling on the top of the rail, the I-shaped wheels are in two rows and are respectively arranged above the corresponding rails, the water pipe is fixed to the bottom of the base plate, the water tank and the water pump are both arranged on the base plate, and the base plate is provided with a first driving member for driving at least one of the I-shaped wheels in each row to rotate.

[0007] By adopting the above technical solution, the first driving member can drive the bottom plate to move on the rails, thereby driving the water tank and the water pipe to move on the rails, expanding the cooling range and eliminating the need to frequently move the water tank, thereby achieving cooling of different positions on the rails, which is very convenient during use.

[0008] The present invention is further configured as follows: four support rods are rotatably connected to the bottom of the base plate, the rotating axes of the support rods are arranged horizontally and perpendicular to the length direction of the rails, one end of the support rods away from the rotating axes is rotatably connected to walking wheels, and a second driving component is provided on the base plate for driving the support rods to switch and fix between horizontal and vertical states.

[0009] By adopting the above technical solution, when the support rod is rotated to a vertical state, the bottom of the walking wheel is lower than the I-wheel. At this time, the walking wheel contacts the ground and the base plate can walk on the ground, thereby facilitating the movement of the base plate. The second driving member can drive the support rod to adjust and fix its position, thereby facilitating the switching of the base plate between different states.

[0010] The present invention is further configured as follows: the second driving member includes a driving rod rotatably arranged in the middle of the base plate, the driving rod is arranged along the length direction of the rail, and the two ends of the base plate are rotatably connected with driving shafts. The two driving shafts are arranged horizontally along the base plate, and the two ends of the driving shaft are respectively coaxial and fixed with the rotating shaft of the corresponding support rod. A worm gear is provided on the driving shaft, and a worm that cooperates with the worm gear is sleeved and fixed on the driving rod.

[0011] By adopting the above technical solution, after the driving rod is rotated, the driving shaft is driven to rotate through the worm gear transmission, thereby realizing the synchronous driving of all the support rods. The adjustment process is very convenient, and the worm gear has a self-locking property. When the support rod is adjusted into place, the support rod can also be fixed, which simplifies the structure and makes the working process reliable.

[0012] The present invention is further configured as follows: the first driving member includes a dual-axis motor arranged at the front end of the base plate, the output shaft of the dual-axis motor is arranged horizontally along the base plate, and the output shafts at both ends of the dual-axis motor are connected to the I-shaped pulley on the corresponding side of the front end of the base plate through a belt drive.

[0013] By adopting the above technical solution, the dual-axis motor is turned on, and the corresponding I-shaped wheels can be driven to rotate through the belt transmission, thereby driving the base plate to move on the rail. The belt transmission is used to drive the I-shaped wheels to rotate. When the I-shaped wheels are stuck, the belt transmission slips, thereby protecting the dual-axis motor.

[0014] The present invention is further configured as follows: a first driven pulley is fixedly connected to the I-shaped pulley, a first driving pulley is rotatably connected to the top of the base plate and is connected to the first driven pulley via a belt, a first driven gear is fixed to the first driving pulley, and a driving gear that can mesh with the first driven gear is provided on the output shaft of the dual-axis motor.

[0015] By adopting the above technical solution, when the driving base plate moves on the rail, the double-axis motor is turned on, the driving gear drives the first driven gear to rotate, and then the first driven pulley is driven to rotate through the first driving pulley, and finally the driving of the I-shaped track is realized. The gear transmission and the belt transmission are coordinated, and the power output of the double-axis motor is more stable. At the same time, the transmission ratio has a large adjustable range and strong adaptability.

[0016] The present invention is further configured as follows: an intermediate pulley coaxially arranged with the rotating shaft of the support rod is rotatably connected to the support rod near the front end of the base plate, a second driven pulley connected to the intermediate pulley by a belt is fixedly connected to the walking wheel, a second driving pulley connected to the intermediate pulley by a belt transmission is rotatably connected to the base plate, a second driven gear capable of meshing with the driving gear is coaxially fixedly connected to the second driving pulley, the driving gear is arranged between the first driven gear and the second driven gear, the dual-axis motor is slidably arranged on the base plate along the length direction of the base plate, and a shifting device driving the dual-axis motor to slide to mesh with the first driven gear or the second driven gear is provided on the base plate.

[0017] By adopting the above technical solution, it is only necessary to control the shifting device to change the position of the dual-axis motor, engage the driving gear with different driven gears, and drive the travel wheel or the I-shaped wheel to rotate through a dual-axis motor.

[0018] The present invention is further configured as follows: a motor seat is slidably connected to the base plate along the length direction of the base plate, baffles are provided at both front and rear ends of the motor seat, the baffles extend downward to both sides of the driving shaft at the front end of the base plate, the shifting device includes a rocker arm fixedly arranged on the driving shaft at the front end of the base plate, a push rod is provided between the two baffles, both ends of the push rod are fitted with corresponding baffles, a protrusion is fixedly connected to the push rod toward the driving shaft, the protrusion is perpendicular to the push rod and is rotatably connected to the end of the rocker arm away from the driving shaft.

[0019] By adopting the above technical solution, when working, after the driving rod drives the driving shaft to rotate, the driving shaft also drives the rocker arm to rotate, and the rocker arm drives the push rod to slide along the length direction of the bottom plate, and then pushes the baffle to drive the motor seat to slide. When in use, you only need to rotate the driving rod. When adjusting the position of the support rod, you can also complete the switching of the dual-axis motor position at the same time. The structure is simple and easy to operate.

[0020] The present invention is further configured as follows: there are four water pipes, which are symmetrically arranged in pairs on both sides of the corresponding rails; a main pipe is arranged on the bottom plate; the four water pipes are connected to the main pipe via branch pipes; the water inlet end of the water pump is connected to the water tank; the water outlet end of the water pump is connected to the main pipe; the branch pipes are slidably arranged on the bottom plate in a vertical direction; and a third driving member is provided on the bottom plate for driving the branch pipes to rise when the support rod rotates downward.

[0021] By adopting the above technical solution, when the base plate moves on the ground, the third driving member can drive the branch pipe to slide upward, thereby increasing the distance between the water pipe and the ground, facilitating the movement of the base plate, and driving the branch pipe to move while the support rod rotates downward. There is no need for additional control of the branch pipe, and the operation is very convenient.

[0022] In summary, the present invention includes at least one of the following beneficial technical effects:

[0023] The water pump can be remotely controlled through a display or mobile phone APP, making the operation more convenient;

[0024] When in use, one only needs to rotate the driving rod to achieve the change of the positions of the support rod, the water pipe and the dual-axis motor, which simplifies the operation steps and improves the operation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0033] like Figure 1-6 As shown, a railway track temperature control system disclosed in the present invention includes a water pipe 2, a water tank 11 and a water pump 12. The water pipe 2 is arranged parallel to the rail 9. A nozzle facing the rail 9 is provided on the water pipe 2. In order to save water resources, an atomizing nozzle 21 is used as the nozzle. The water tank 11 is connected to the water pipe 2. A water pump 12 is provided between the water tank 11 and the water pipe 2. The water pump 12 delivers the water in the water tank 11 into the water pipe 2, and at the same time ensures that the water pressure in the water pipe 2 can meet the requirements of the atomizing nozzle 21, so as to stably realize the cooling of the rail 9.

[0034] In order to facilitate the movement of the water pipe 2 and the water tank 11, it also includes a base plate 1 placed on the rail 9. The bottom of the base plate 1 is rotatably connected to an I-shaped wheel 3 that can roll on the top of the rail 9. There are several I-shaped wheels 3 at the bottom of the base plate 1 and they are arranged in two rows. The two rows of I-shaped wheels 3 are respectively arranged above the corresponding rails 9. A first driving member for driving the I-shaped wheels 3 to rotate is provided on the base plate 1. In order to simplify the structure, the first driving member can drive at least one of the I-shaped wheels 3 in each row to rotate. In this embodiment, there are four I-shaped wheels 3, which are respectively arranged at the four corners of the base plate 1. The first driving member drives the two I-shaped wheels 3 near the front end of the base plate 1 to rotate.

[0035] In order to improve the space utilization rate on the bottom plate 1, the water storage tank 11 is arranged in the middle of the bottom plate 1, and the water pump 12 is arranged at the rear end of the bottom plate 1. The first driving member includes a double-shaft motor 4 arranged at the front end of the bottom plate 1. The output shaft of the double-shaft motor 4 is arranged horizontally along the bottom plate 1. The two ends of the output shaft of the double-shaft motor 4 extend to the top of the corresponding side of the I-shaped wheel 3 respectively. The I-shaped wheel 3 near the front end of the bottom plate 1 is connected to the corresponding output shaft on the double-shaft motor 4 through a belt drive. When the double-shaft motor 4 is turned on, the corresponding I-shaped wheel 3 can be driven to rotate through the belt drive, thereby driving the bottom plate 1 to move on the rail 9.

[0036] In addition, distance sensors for detecting the distance between each temperature sensor and the bottom plate 1 can also be added to the bottom plate 1. When the temperature sensor detects that the temperature is too high, the dual-axis motor 4 drives the bottom plate 1 to automatically move to the area where the corresponding temperature sensor is located, thereby realizing automatic cooling of the rail 9. The cooling method is flexible, the cooling efficiency is high, and the response is rapid.

[0037] In order to stably realize the driving of the I-shaped wheel 3, a first driven pulley 31 is provided on the side of the I-shaped wheel 3, the first driven pulley 31 is coaxially arranged and fixedly connected with the I-shaped wheel 3, and a first driving pulley 32 is rotatably connected above the bottom plate 1, the first driving pulley 32 is arranged on one side of the output shaft of the dual-axis motor 4, and a first driven gear 321 is fixedly connected to the side of the first driving pulley 32, the first driven gear 321 is coaxially arranged and fixedly connected with the first driving pulley 32, and a driving gear 41 meshing with the first driven gear 321 is fixedly connected to the output shaft of the dual-axis motor 4. When driving, the dual-axis motor 4 is turned on, and the driving gear 41 drives the first driven gear 321 to rotate, and then drives the first driven pulley 31 to rotate through the first driving pulley 32, finally realizing the driving of the I-shaped road, and the gear transmission is coordinated with the belt transmission, the power output of the dual-axis motor 4 is more stable, and the transmission ratio has a large adjustable range and strong adaptability.

[0038] Because the water pipe 2 needs to be set lower than the I-wheel 3, the base plate 1 can only walk on the rails 9. In order to facilitate the movement of the base plate 1 on the ground, four support rods 5 are rotatably connected to the bottom surface of the base plate 1. The four support rods 5 are symmetrically arranged in pairs. The rotating shafts of the support rods 5 are arranged along the width direction of the base plate 1, and a walking wheel 51 is rotatably connected to the end of the support rod 5 away from its rotating shaft. A second driving component is provided on the base plate 1 for driving the support rod 5 to switch and fix between the horizontal and vertical states. When the support rod 5 is rotated to the vertical state, the bottom of the walking wheel 51 is lower than the I-wheel 3. At this time, the walking wheel 51 contacts the ground, and the base plate 1 can walk on the ground, thereby facilitating the movement of the base plate 1. The second driving component can drive the support rod 5 to adjust and fix its position, so as to facilitate the switching of the base plate 1 between different states.

[0039] To facilitate the driving of the support rod 5 to rotate, the second driving member includes a driving rod 6 rotatably arranged in the middle of the base plate 1. The driving rod 6 is arranged along the length direction of the base plate 1, and a driving shaft 13 is rotatably connected at both ends of the base plate 1. The driving shaft 13 is arranged horizontally along the base plate 1 and is located above the driving rod 6. Both ends of the driving shaft 13 are coaxial and fixedly arranged with the rotating shaft of the support rod 5 at the same end. A worm gear 131 is fixedly connected to the driving shaft 13, and the worm gear 131 is coaxially arranged with the driving shaft 13. A worm 61 is sleeved on the driving rod 6, and the worm 61 is fixedly connected to the driving rod 6 and meshes with the corresponding worm gear 131. After the driving rod 6 is rotated, the worm gear 131 and the worm gear 61 are transmitted to drive the driving shaft 13 to rotate, thereby realizing the synchronous driving of all the support rods 5. The adjustment process is very convenient, and the worm gear 131 and the worm gear 61 have self-locking performance. When the support rod 5 is adjusted into place, the support rod 5 can also be fixed, which simplifies the structure and makes the working process reliable.

[0040] To facilitate the driving of the base plate 1 to move on the ground, an intermediate pulley 52 is rotatably connected to the support rod 5 at the front end of the base plate 1, and the intermediate pulley 52 is coaxially arranged with the rotating axis of the support rod 5. A second driven pulley 511 is fixedly connected to the side of the walking wheel 51, and the second driven guide wheel is connected to the intermediate pulley 52 by a belt. A second driving pulley 53 is rotatably connected to the base plate 1 and is connected to the intermediate pulley 52 by a belt transmission. By setting the intermediate pulley 52, even if the support rod 5 rotates when in use, the driving of the walking wheel 51 can still be achieved after the driving pulley is rotated.

[0041] In order to improve the utilization rate of the dual-axis motor 4, a second driven gear 54 that can mesh with the driving gear 41 is coaxially fixedly connected to the second driving pulley 53, and the driving gear 41 is arranged between the first driven gear 321 and the second driven gear 54. In this embodiment, the first driven gear 321, the driving gear 41 and the second driven gear 54 are arranged on the base plate 1 from front to back, and the dual-axis motor 4 is slidably arranged on the base plate 1 along the length direction of the base plate 1. A shifting device for driving the dual-axis motor 4 to slide to mesh with the first driven gear 321 or the second driven gear 54 is provided on the base plate 1. It only needs to control the shifting device to change the position of the dual-axis motor 4 to mesh the driving gear 41 with different driven gears. Through a dual-axis motor 4, the walking wheel 51 or the I-shaped wheel 3 can be driven to rotate.

[0042] To ensure that the driving gear 41 can mesh with the first driven gear 321 and the second driven gear 54 after sliding, the rotating shafts of the first driven gear 321 and the second driven gear 54 are located in the same horizontal plane, and the rotating shaft of the driving gear 41 is higher than the first driven gear 321 and the second driven gear 54. By staggering the first driven gear 321 and the second driven gear 54 with the driving gear 41, it is possible to avoid direct contact between the teeth of the driving gear 41 and the teeth of the first driven gear 321 or the second driven gear 54, thereby ensuring that after the dual-axis motor 4 slides, the teeth of the driving gear 41 can be embedded in the teeth of the first driven gear 321 or the second driven gear 54.

[0043] In order to facilitate the sliding of the dual-axis motor 4, a motor seat 42 is slidably connected to the bottom plate 1 along the length direction of the bottom plate 1. The motor seat 42 and the bottom plate 1 are slidably connected through a dovetail groove and a dovetail block. Baffles 421 are provided at both ends of the motor seat 42. The baffle 421 is arranged below the motor seat 42. The top of the baffle 421 is fixedly connected to the motor seat 42. The baffle 421 extends downward to both sides of the driving shaft 13 at the front end of the bottom plate 1. The shifting device includes a swing rod 7 fixedly arranged on the driving shaft 13 at the front end of the bottom plate 1. The swing rod 7 is perpendicular to the driving shaft 13. The driving shaft 13 is provided, and a push rod 71 is provided between the two baffles 421. The two ends of the push rod 71 are fitted with the corresponding baffles 421. The push rod 71 always maintains a horizontal state, and the push rod 71 is located above the driving shaft 13. A protrusion 72 is fixedly connected to the push rod 71 toward the driving shaft 13. The protrusion 72 is arranged perpendicular to the push rod 71. The length of the protrusion 72 is greater than or equal to the diameter of the driving shaft 13. The end of the swing rod 7 away from the driving shaft 13 is rotatably connected to the protrusion 72, and the rotation axis of the swing rod 7 and the protrusion 72 is arranged parallel to the driving shaft 13. After the driving shaft 13 rotates, the swing rod 7 is driven to rotate, and the swing rod 7 drives the push rod 71 to slide along the length direction of the bottom plate 1, thereby pushing the baffle 421 to drive the motor seat 42 to slide.

[0044] When the driving shaft 13 drives the swing rod 7 to be in a vertical state, the support rod 5 is in a horizontal state, the swing rod 7 and the push rod 71 are located above the driving shaft 13, the driving gear 41 is meshed with the first driven gear 321, and the double-axis motor 4 drives the I-shaped wheel 3 to rotate; when the driving shaft 13 drives the support rod 5 at the front end of the bottom plate 1 to rotate toward the front end of the bottom plate 1 to a vertical state, the swing rod 7 rotates to a horizontal state, the push rod 71 pushes the double-axis motor 4 to slide to the rear of the bottom plate 1, the driving gear 41 is meshed with the second driven gear 54, and the double-axis motor 4 can drive the walking wheel 51 to rotate. Only the driving rod 6 needs to be rotated, and when the position of the support rod 5 is adjusted, the position switching of the double-axis motor 4 can be completed at the same time, which has a simple structure and is easy to operate.

[0045] In order to further improve the cooling effect of the rail 9, there are four water pipes 2, which are symmetrically arranged on both sides of the corresponding rails 9. A main pipe 8 is arranged on the bottom plate 1, and the main pipe 8 is arranged along the width direction of the bottom plate 1 and is arranged above the bottom plate 1. The four water pipes 2 are connected to the main pipe 8 through a branch pipe 81. The water inlet pipe 2 of the water pump 12 is connected to the water storage tank 11, and the water outlet end of the water pump 12 is connected to the main pipe 8. The branch pipe 81 is slidably arranged on the bottom plate 1 in the vertical direction. A third driving member is provided on the bottom plate 1 to drive the branch pipe 81 to rise when the support rod 5 rotates downward. When the bottom plate 1 walks on the ground, the third driving member can drive the branch pipe 81 to slide upward, thereby increasing the distance between the water pipe 2 and the ground, and facilitating the movement of the bottom plate 1.

[0046] The third driving member includes a vertically arranged rack 82, the top end of which is fixedly connected to the main pipe 8 and passes through the bottom plate 1. A third gear 83 is coaxially fixedly connected to the driving rod 6, and the third gear 83 is meshed with the rack 82. When the support rod 5 is in a horizontal state, the third gear 83 is meshed with the highest point of the rack 82. After rotating the driving rod 6, the third gear 83 drives the rack 82 to slide upward, thereby driving the water pipe 2 to slide upward, increasing the distance between the water pipe 2 and the ground.

[0047] The implementation principle of this embodiment is as follows: during normal operation, the bottom plate 1 is located above the rail 9, the I-shaped wheel 3 rolls on the top of the rail 9, the dual-axis motor 4 is meshed with the first driven gear 321, driving the I-shaped wheel 3 to rotate, and the bottom plate 1 is moved to the top of the rail 9 that needs to be cooled, and the water pump 12 is turned on, and the water sprayed by the atomizing nozzle 21 on the water pipe 2 can cool the rail 9;

[0048] When moving, the driving rod 6 is rotated, the water pipe 2 slides upward, and the support rod 5 rotates downward. At this time, the swing rod 7 rotates to a horizontal state under the drive of the driving shaft 13, and the push rod 71 pushes the dual-axis motor 4 to slide toward the rear of the base plate 1. The driving gear 41 engages with the second driven gear 54. At this time, the dual-axis motor 4 can drive the walking wheel 51 to rotate.

[0049] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
