[0003] In the prior art, there are two ways of polishing operation, i.e. large machine polishing and small machine polishing.

The wheel support assembly 10 is used to guide the device walking along the direction of the steel rail, and at the same time, the presence of the reset spring 104 and the sliding block makes the whole machine move along the horizontal direction under the condition that the profiling wheel assembly 13 is always tangent to the steel rail when the angle is turned over, solving the problem that the whole machine must be turned over, preventing the device from rolling over, dumping, and interfering with the steel rail, etc. The rail crossing rod connecting assembly 14 is detachably connected with the rail crossing rod fixing block 69 at the end of the rail crossing rod 70, and the rail crossing rod connecting assembly 14 ensures the quickness and accuracy of the connection with the rail crossing support mechanism 7.

[0087] Specifically, the components in the walking support mechanism 4 are connected by bolt fixation. In actual work, when the device is placed on the rail, the two side wheels of the leaning wheel support assembly 10 hold the rail in the middle, preventing the device from falling off the rail; during the device overturning process, since the profiling wheel in the profiling wheel assembly 13 is always in contact with the rail and its rotation axis is fixed, and the leaning wheel assembly 109 is always on the rail and does not move, the other functional mechanisms move on the sliding block assembly 107 along with the spring shaft 105 (the spring shaft 105 functions as a reset) and the guide shaft 106 in the leaning wheel support assembly 10, driving the device to move horizontally. The profiling wheel assembly 13 is always in contact with the rail, so whether the device moves along the rail or the device rotates, the profiling wheel assembly is always in contact with (i.e., tangent to) the rail line, ensuring the continuity of the polishing angle and thus ensuring the polishing quality. The profiling wheel assembly 13 is transitionally connected to the connecting shaft assembly 11 by bolts, and the polishing transmission mechanism 5 is connected to the connecting shaft assembly 11 by bolts and keys. During the device overturning process, the profiling wheel assembly 13, the connecting shaft assembly 11, and the polishing transmission mechanism 5 rotate together, and the grinding wheel realizes line contact with the rail at all times through the lifting mechanism 6, thereby realizing the polishing work.

[0088] A control system 2, the polishing motor 17 of the polishing transmission mechanism 5, the stepping motor 31 of the lifting mechanism 6, the overturning motor 48 of the angle deflection mechanism 3, and the power source 1 (power battery pack) are electrically connected to the control system 2, respectively, and the control system 2 includes a control box 61 with a profile data analysis module.

[0090] Main function: control box 61 contains plc, motor control system (or motor control module), profile data analysis module, for data and control command analysis and transmission, so as to achieve the motor according to the requirements of the work; wherein, the profile data analysis module can adopt profile analysis software, the control box 61 is embedded in the profile analysis software, which can be measured by the operator using the profile measuring instrument to upload the profile of the profile analysis software, and then automatically analyze the profile of the steel rail to be maintained. The operation panel 63 can display the polishing angle, polishing amount, polishing precision, motor switch touch button and analysis data result, which is mainly used for display and detection of polishing state; The emergency stop button 67 is used for stopping in emergency; The boat-shaped switch 66 is used for power supply and power failure of the operation panel 63; The operation handle 64 is used for manual guidance of lifting motor, turning motor 48 to realize control of polishing amount, polishing precision and turning angle; The air switch assembly 65 is used to control the power supply and power failure of the whole equipment control system 2.

[0091] The application provides a lithium battery steel rail intelligent profile grinding machine, which uses profile analysis software embedded in the control system 2 to analyze the profile of the steel rail to be polished, and uses the polishing scheme formulated as the basis, adopts a power battery as the power source, automatically adjusts or manually adjusts the polishing transmission mechanism 5, the lifting mechanism 6 and the angle deflection mechanism 3 through the operation of the operation panel 63 and the operation handle 64, so as to polish the steel rail.

[0092] The combination of power battery and direct current brushless motor replaces the internal combustion engine in the prior art as the driving force, solves the problems of large vibration, large noise, environmental pollution and adverse effects on the health of operators of the polishing machine, has the advantages of small vibration, small noise and environmental friendliness; The lifting mechanism 6 adopts an integrated operation combination of stepping motor 31+hand wheel, solves the problems of poor polishing quality and relatively low feeding precision of the polishing machine, has the advantages of high feeding precision and excellent polishing quality; The profile data analysis module embedded in the new control system 2 can automatically analyze and generate a polishing scheme, solves the problems of manual experience judgment and high labor intensity of polishing, has the advantages of intelligence and high polishing efficiency; The walking support mechanism 4 is connected with the rail crossing support mechanism 7, so that the equipment can be stably placed on the steel rail without falling off and rolling over, solves the problems of large labor intensity of operators caused by large weight of the equipment and lack of support, has the advantages of stable structure and low operation intensity.

[0093] In summary, the lithium battery steel rail intelligent profile grinding machine not only solves the problems of the existing polishing machine, but also further improves the performance and quality of the polishing machine, and makes great contributions to the development of small, intelligent, automatic and digital polishing machines.

[0095] The beneficial effects of the technical scheme of the utility model are as follows:
