Description

Technical Field

[0001] This utility model relates to the field of rail transit maintenance equipment technology, and in particular to an automatic rail cooling device. Background Technology

[0002] With the rapid development of railway transportation, especially the popularization of high-speed railways, higher requirements have been placed on the maintenance of railway infrastructure. As the foundation of train operation, the condition of rails is directly related to train safety. Under conditions such as high temperatures in summer or frequent train passage, the temperature of rails will rise sharply, generating excessive thermal stress, which may cause the rails to bulge, deform or even break, threatening train safety.

[0003] Cooling equipment capable of automatically traveling along rails has emerged on the market. These devices typically integrate a walking system and a spraying system, enabling them to cool long distances of rails without human intervention. However, existing automatic cooling equipment still has shortcomings in its structural design. Railway tracks are not entirely straight, containing numerous curved sections. Existing automatic cooling equipment often employs a simple structure where both wheels are rigidly connected to the same drive shaft. While this structure is adequate for straight tracks, it becomes problematic when entering curved tracks. Due to the different track lengths on the inner and outer sides of the curve, the inner and outer wheels are required to rotate at different speeds. The rigidly connected drive structure cannot meet this requirement, leading to sliding friction or dragging on one side of the wheel. This not only increases energy consumption and wear but, more seriously, causes instability, resulting in vibrations, jamming, or even derailment.

[0004] Therefore, this utility model proposes an automatic rail cooling device to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems in existing automatic rail cooling equipment, such as unstable driving, jamming, or even derailment caused by the mismatch in the speed of the inner and outer wheels when passing through curved tracks, this utility model aims to provide an automatic rail cooling device with an improved structure that can effectively solve the above problems.

[0006] This utility model provides an automatic cooling device for steel rails, including: a base plate, and a traveling mechanism and a spray cooling mechanism disposed on the base plate; the traveling mechanism includes a motor, a differential, equipment wheels, and a transmission component connected between the motor and the differential.

[0007] The differential is used to connect between the two equipment wheels and can automatically adjust the speed of the two equipment wheels.

[0008] Furthermore, the motor is combined with the differential through the transmission assembly via a transmission connection. The differential is then connected to the equipment wheels via a transmission connection, together forming a drive unit capable of adaptive cornering. When the motor is working, power is transmitted to the differential via the transmission assembly, and then distributed by the differential to the equipment wheels on both sides, thereby driving the entire equipment to move automatically along the rail.

[0009] Preferably, the transmission assembly specifically includes a second synchronous gear fixedly connected to the output shaft of the motor, a first synchronous gear fixedly connected to the input end of the differential, and a synchronous toothed belt meshing between the first synchronous gear and the second synchronous gear. Through the cooperation of the synchronous gear and the synchronous toothed belt, precise and slip-free power transmission between the motor and the differential is achieved.

[0010] Preferably, the traveling mechanism further includes a connecting frame for mounting on the rail, a telescopic sleeve slidably disposed inside the connecting frame, a device spring disposed inside the telescopic sleeve, and a stop plate for abutting against the rail fixedly connected to one end of the telescopic sleeve. This structure, through the elastic force of the device spring, enables the stop plate to continuously and elastically abut against the side of the rail, thereby stably clamping the device on the rail and preventing shaking or derailment during operation.

[0011] Preferably, the spray cooling mechanism includes a water tank fixedly connected to the base plate of the equipment, a water pump and an atomizing nozzle. The inlet of the water pump is connected to the water tank, and its outlet is connected to the atomizing nozzle through a pipeline, for pumping the cooling liquid stored in the water tank to the atomizing nozzle and spraying it out.

[0012] Preferably, as a further limitation of the above-mentioned pipeline system, the pipeline connecting the water pump of the connecting device and the atomizing nozzle includes an L-shaped connecting pipe and a first connecting pipe. The spray cooling mechanism also includes a second support plate and a support block for supporting and fixing the pipeline. The second support plate and the support block are both fixed on the water tank of the device and are respectively fixedly connected to the first connecting pipe and the L-shaped connecting pipe, ensuring the structural stability of the pipeline system and preventing the pipeline from becoming loose due to vibration during the operation of the device.

[0013] This utility model has the following beneficial effects: 1. This utility model solves the problem of unstable driving, jamming, or even derailment caused by the inner and outer wheels rotating at the same speed when the rail cooling equipment passes through curved tracks in the prior art. By setting up a motor, transmission components, differential, and equipment wheels, and connecting the differential between the two equipment wheels, this invention achieves the technical effect of enabling the equipment to automatically adjust the speed difference between the inner and outer equipment wheels, thereby smoothly passing through curves and improving the stability and automation of the equipment.

[0014] 2. This utility model, by setting a connecting frame and incorporating a sliding telescopic sleeve, equipment spring, and a stop plate inside the connecting frame, solves the problem in the prior art where the connection between the equipment and the rail is unstable and prone to loosening or derailment due to changes in rail width or vibration. It achieves the technical effect of using the elastic force of the spring to keep the stop plate elastically against the side of the rail, realizing adaptive and stable clamping of the rail, effectively preventing equipment derailment, and ensuring safe operation.

[0015] 3. This utility model solves the problems of low automation and low efficiency in rail cooling operations in the prior art by integrating the traveling mechanism that can automatically adapt to curves and the spray cooling mechanism on the same equipment base plate. In particular, it is difficult to achieve continuous and uninterrupted operation on complex lines. It achieves the technical effect of realizing fully automatic travel and synchronous cooling operation of the equipment along the rails, and can complete the cooling treatment of long-distance rails, including curves, without manual intervention. This significantly improves the work efficiency and reduces the labor intensity. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 5 This utility model provides an automatic rail cooling device, which aims to solve the problem that existing rail cooling devices cannot automatically adapt to curved tracks for smooth travel and synchronous operation.

[0020] like Figure 1 As shown, the automatic rail cooling device includes a base plate 101, a traveling mechanism 1 and a spray cooling mechanism 2 mounted on the base plate 101. The base plate 101 serves as the mounting base for the entire device. The traveling mechanism 1 drives the device to travel automatically along the rail, and the spray cooling mechanism 2 sprays the rail to cool it. Through the coordinated work of the traveling mechanism 1 and the spray cooling mechanism 2, the automatic cooling process of the rail is achieved.

[0021] Specifically, the walking mechanism 1 is designed to enable automatic and stable travel on the rails. Firstly, to achieve a stable connection between the equipment and the rails, the walking mechanism 1 includes connecting strips 1011 fixedly connected to both sides of the equipment base plate 101. A connecting block 1012 is fixedly connected to one side of each connecting strip 1011, and a connecting frame 1013 is fixedly connected to the bottom of the connecting block 1012. The connecting frame 1013 is used to fit over the rails from above. To further ensure the stability and adaptability of the clamping, the interior of the connecting frame 1013... The device is equipped with a telescopic sleeve 1014, a device spring 1015, and a stop plate 1016. The telescopic sleeve 1014 is slidably disposed in the inner cavity of the connecting frame 1013. The device spring 1015 is housed in the telescopic sleeve 1014. The stop plate 1016 is fixedly connected to the end of the telescopic sleeve 1014 away from the device spring 1015. When the device is installed on the rail, the device spring 1015 pushes the stop plate 1016 to elastically abut against the side of the rail, thereby firmly and flexibly clamping the device on the rail.

[0022] Provide power and transmission for the equipment, refer to Figure 2 and Figure 3 A connecting plate 1010 is fixedly connected to the bottom of the equipment base plate 101, and a motor 107 is fixedly connected to the bottom of the connecting plate 1010 as a power source. Two first support plates 102 are also vertically fixedly connected to the bottom of the equipment base plate 101. The two ends of the rotating rod 103 are rotatably connected between the two first support plates 102 through bearings. A differential 105 is mounted on the rotating rod 103, and the equipment wheel 104 is also mounted on the rotating rod 103. The equipment wheel 104 and the differential 105 form a transmission connection. Next, in order to transmit the power of the motor 107 to the differential 105, the walking mechanism 1 also includes a transmission assembly, which specifically includes a second synchronous gear 108, a first synchronous gear 106, and a synchronous toothed belt 109. The second synchronous gear 108 is fixedly connected to the output shaft of the motor 107, the first synchronous gear 106 is fixedly connected to the input end of the differential 105, and the synchronous toothed belt 109 is meshed between the first synchronous gear 106 and the second synchronous gear 108, thus forming a highly efficient zero-slip transmission.

[0023] To construct a complete four-wheeled chassis, refer to Figure 1 and Figure 2 The traveling mechanism 1 also includes another set of equipment wheels 104 and a corresponding rotating rod 103. The other rotating rod 103 is rotatably connected to the bottom of the equipment base plate 101 through bearing seats at both ends. The other set of equipment wheels 104 are freely rotatably mounted on the other rotating rod 103, serving as a driven wheel set, which together with the aforementioned drive wheel set supports the equipment to roll smoothly on the rail.

[0024] As a preferred embodiment, please refer to Figure 1 and Figure 5The spray cooling mechanism 2 specifically includes a water tank 201, a water pump 202, and an atomizing nozzle 205. The water tank 201 is fixedly connected to the top of the equipment base plate 101 and is used to store cooling liquid. The inlet of the water pump 202 is connected to the water tank 201, and its outlet is connected to the atomizing nozzle 205 through a pipeline. This pipeline specifically includes an L-shaped connecting pipe 206 and a first connecting pipe 204. One end of the L-shaped connecting pipe 206 is connected to the outlet of the water pump 202, and the other end is connected to the first connecting pipe 205. Pipe 204 is connected, and atomizing nozzle 205 is fixedly installed on the first connecting pipe 204. To ensure the stability of the pipeline system, the spray cooling mechanism 2 also includes a second support plate 203 and a support block 207. One end of the second support plate 203 is fixedly connected to one side of the equipment water tank 201, and the other end is fixedly connected to the first connecting pipe 204. The support block 207 is also fixedly connected to one side of the equipment water tank 201 and fixedly connected to the L-shaped connecting pipe 206, thereby firmly fixing the entire pipeline system to the equipment.

[0025] The working principle of this automatic rail cooling device is as follows: When the equipment is started, the motor 107 and the equipment water pump 202 are powered on and work. The power of the motor 107 is precisely transmitted to the differential 105 through the transmission assembly composed of the second synchronous gear 108, the synchronous toothed belt 109 and the first synchronous gear 106. The differential 105 then drives the equipment wheel 104 connected to it to rotate, thereby driving the entire equipment to move along the rail. During the movement, the connecting frame 1013 is always fitted on the rail, and the equipment spring 1015 inside it continuously pushes the abutment plate 1016 to elastically abut against the side of the rail. This adaptive clamping action ensures that the equipment will not derail during movement and can adapt to slight changes in the width of the rail.

[0026] When the equipment travels to a curved track section, the core function of the differential 105 becomes apparent. The equipment wheel 104 located on the outside of the curve needs to travel a longer distance. The differential 105 can automatically distribute torque, allowing the outer equipment wheel 104 to rotate at a higher speed than the inner equipment wheel 104, thereby actively adapting to the speed difference between the inner and outer wheels. In this way, the present invention solves the problem of unstable driving, jamming, or even derailment caused by the mismatch of wheel speeds when the existing equipment travels on curves, and realizes smooth and automatic driving on complex tracks.

[0027] As the equipment moves, the equipment water pump 202 pumps out the cooling liquid in the equipment water tank 201. The liquid passes through the L-shaped connecting pipe 206 and the first connecting pipe 204 and reaches the atomizing nozzle 205. The atomizing nozzle 205 sprays the liquid evenly on the surface of the rail in a mist, quickly removing the heat generated by the high temperature of the rail and completing the cooling operation.
