Description

[0002] In the laying and maintenance of rails in railway transportation, coal mines, ports, mines, etc., rail saws are usually used to cut rails according to the actual application environment on site; existing rail saws mainly use rotating drive parts such as internal combustion engines or AC motors as power, and then drive the saw disk to rotate through a pulley transmission mechanism, thereby cutting the rails based on the saw disk;

[0003] In the Chinese utility model CN219235547U, a "new type of heavy-duty chainsaw with solid-state lithium battery" is proposed. The device includes a chainsaw body and a power mechanism. One end of the chainsaw body is fixedly connected to a chainsaw handle, and the other end of the chainsaw body is installed with a blade. The outer surface of the blade is sleeved with a knife chain. An input interface is installed on one side of the chainsaw body, and a power mechanism is provided on one side of the chainsaw body. A dust suppression mechanism is provided on the other side of the chainsaw body. The latest solid-state lithium battery technology increases the output power of the motor, optimizes the motor transmission part, and adds a set of efficient clutch transmission devices to increase the output torque of the motor.

[0037] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a portable cutting machine specially used for rail cutting in one embodiment of the present invention, a portable cutting machine specially used for rail cutting, including a frame 1, a belt transmission mechanism 2, a gripping end 3, a dust cover 4, an assembly monitoring unit 5 and an operation panel 6; the belt transmission mechanism 2 is arranged on the side of the frame 1; the gripping end 3 is arranged on the frame 1, which is convenient for the staff to hold; the dust cover 4 is detachably connected to the end of the frame 1 through the installation shaft 42, and a saw disk 41 is arranged in the dust cover 4; the assembly monitoring unit 5 is used to monitor whether the saw disk 41 is installed; the operation panel 6 is arranged on the frame 1, and is used to control the power detection unit 7, and the operation of the saw disk 41 is controlled by the power detection unit 7.

[0038] In this embodiment, a belt drive mechanism 2 is provided on the frame 1 to conveniently drive the entire saw disk 41 to rotate, and an assembly monitoring unit 5 is provided on the frame 1 to monitor whether the saw disk 41 is properly installed, and an operation panel 6 is used to facilitate the start and stop of the device, and a power detection unit 7 is provided to monitor the operating status of the saw disk 41 to avoid dangerous situations, thereby greatly improving the safety and stability of the device during use. The operating principle of the rail sawing machine is to provide power through an internal motor and transmit the power to the saw disk 41 through gears, belts and hydraulic transmission structures, thereby ensuring efficient cutting, wherein the saw disk 41 is a high-hardness alloy to ensure the cutting efficiency of the saw disk 41, and the hardness of the saw disk 41 is much greater than the hardness of the rail material.

[0039] In one embodiment, see Figure 1 In order to improve the heat dissipation efficiency of the device, a heat dissipation hole 11 is opened on the frame 1 and located at the upper end of the belt transmission mechanism 2; a rechargeable power supply 12 is installed in the frame 1, and a mounting frame 13 is set at the end of the frame 1, and a mounting cavity 131 is opened in the mounting frame 13, and a connecting port 132 is set on the inner wall of the mounting cavity 131, and an assembly monitoring unit 5 is set in the connecting port 132.

[0040] In this embodiment, a heat dissipation hole 11 is provided on the frame 1 to facilitate the dissipation of heat generated when the internal hydraulic components and the belt drive mechanism 2 are in operation, thereby avoiding excessive heat accumulation inside the frame 1, which may damage the internal electronic components. Secondly, a detachable rechargeable power supply 12 is provided on the frame 1 to facilitate powering the device, and a mounting frame 13 is provided at the end of the frame 1 to facilitate setting the saw disc 41 in the mounting cavity 131.

[0041] In one embodiment, see Figure 1 and Figure 5 In order to improve the holding efficiency of the holding end 3 of the device in winter, the holding end 3 includes a first handle 31 and a second handle 32, both of which are arranged on the frame 1, and the outer walls of the first handle 31 and the second handle 32 are sleeved with a heating mechanism 9, and the frame 1 is also provided with a temperature detection unit 8, wherein the temperature detection unit 8 includes a first temperature sensor 81 and a second temperature sensor 82, wherein the first temperature sensor 81 is arranged on the frame 1, and the second temperature sensor 82 is arranged in the heating mechanism 9, and the heating mechanism 9 includes at least two sleeves 91 and a plurality of electric heating wires 92, and the first handle 31 and the second handle 32 are both provided with sleeves 91, and the second temperature sensor 82 is arranged in the sleeve 91, and the electric heating wire 92 is also arranged in the sleeve 91.

[0042] In this embodiment, the portability of the entire device is improved by arranging a first handle 31 and a second handle 32 on the frame 1. At the same time, it is convenient for the staff to hold it during the cutting process. A first temperature sensor 81 is arranged on the frame 1 to monitor the external ambient temperature, and the temperature of the first temperature sensor 81 is transmitted to the processor 61. The temperature data is analyzed by the processor 61, and the electric heating wire 92 is started at the same time to heat the inside of the sleeve 91. The internal temperature of the sleeve 91 is detected by the second temperature sensor 82. This can improve the work efficiency of the staff in winter, avoid the situation where the first handle 31 and the second handle 32 are too cold, improve the stability of the staff during use, and thus ensure the cutting efficiency.

[0043] In a preferred embodiment, see Figure 1 - Figure 5In order to facilitate the monitoring efficiency of the rail saw machine, the monitoring unit 5 is assembled and includes a pressure sensor 51, an infrared sensor 52 and a warning end 53; the pressure sensor 51 is arranged in the connection port 132, and is used to monitor whether the saw disc 41 is installed properly, and the outer wall of the frame 1 is provided with an infrared sensor 52, the warning end 53 is arranged on the frame 1, and is used to warn the user, the warning end 53 includes a speaker 531 and a warning light 532 installed on the frame 1, the operation panel 6 includes a processor 61, the operation panel 6 is provided with an operation button 62, the processor 61 is provided with a current sampling circuit 63 and a timer 64, the power detection unit 7 includes a speed detection sensor 71, a torque detection sensor 72 and a broken tooth detection sensor 73, wherein the speed sensor, the torque sensor and the broken tooth sensor are all arranged on the frame 1.

[0044] In this embodiment, the pressure sensor 51 is mounted on the clamping device or flange of the saw disk 41 to ensure that the clamping force can be accurately measured, and a suitable pressure sensor 51 is selected to ensure that its range and accuracy meet the requirements. The specific model of the pressure sensor 51 selected in this application is PT124G-111. Zero-point calibration is performed under no-load conditions to ensure accurate sensor readings, and full-scale calibration is performed under known loads to ensure sensor linearity. The pressure sensor 51 is connected to the current sampling circuit 63 in the processor 61 for real-time monitoring of the clamping force, and the upper and lower limit thresholds of the clamping force are set in the processor 61 according to equipment requirements. The clamping force data is monitored in real time to ensure that it is within the set range. When the clamping force exceeds the threshold, the system automatically alarms, and the warning light 532 and the speaker 531 give a dual alarm to prompt checking the installation status of the saw disk 41, and the clamping force data is recorded through the processor 61 to facilitate subsequent analysis and troubleshooting, and to generate monitoring reports regularly to evaluate the installation of the saw disk 41. The state and operation of the equipment are monitored, and the pressure sensor 51 and the data acquisition system are regularly checked to ensure their normal operation. The installation state of the saw disc 41 is adjusted according to the monitoring results to ensure that the clamping force is within a reasonable range. The infrared sensor 52 is of model E1450 and is arranged outside the frame 1 to cooperate with the speed detection sensor 71 to detect the speed of the saw disc 41. A reflective mark is attached to the saw disc 41, and the reflective mark on the saw disc 41 is measured by the infrared light emitted by the infrared sensor 52, and finally the speed sensor is used to detect the reflected light when the mark passes, so as to calculate the speed of the saw disc 41. The torque detection sensor 72 is of model DTNJ-1050B-100Nm. The torque detection sensor 72 is used to monitor the torque change of the saw disc 41 when cutting the rails to ensure the efficiency, safety and life of the saw disc 41 during the cutting process. When the saw disc 41 of the rail sawing machine cuts the rails, it will be subject to resistance from the material, resulting in torque generated by the saw disc 41 and the drive shaft;The torque detection sensor 72 monitors the torque value in real time by measuring the torsional deformation on the drive shaft or the saw disk 41. The specific principle is to stick a strain gauge on the drive shaft. When the shaft is subjected to torque, it deforms, and the resistance value of the strain gauge changes. The electrical signal is converted into an electrical signal through a bridge circuit, and the electrical signal is transmitted to the processor 61 for analysis. The torque detection sensor 72 is installed between the drive shaft and the saw disk 41, and is connected through a coupling or a flange. It can be used to measure the torque of the saw disk 41. The outer edge of the saw disk 41 forms cutting teeth, and the cutting teeth are made of a material with a higher hardness than the rail (such as the above-mentioned metal oxides, ceramic oxides or metal ceramic oxides). The cutting operation is almost wear-free, and gaps are formed between the cutting teeth. The gap is conducive to chip removal, increases the contact area with the air, and dissipates heat, thereby avoiding the accumulation of chips at the cutting position, which is not conducive to the cutting operation. Good heat dissipation performance is conducive to reducing the temperature of the saw disk 41 and the rail, avoiding the decrease in strength, stiffness or hardness of the saw disk 41 due to the increase in temperature, and also avoiding excessive temperature increase when the rail is cut. The mechanical properties are reduced due to the change of crystal phase structure (such as bluing) caused by the saw disk 41. The saw disk 41 is made of wear-resistant material (such as high-hardness metal oxide, ceramic oxide or metal ceramic oxide). As the cutting proceeds, the outer diameter of the saw disk 41 does not decrease substantially. The broken tooth detection sensor 73 is installed on the bracket to detect whether the cutting teeth are broken. The signal output end of the broken tooth detection sensor 73 is connected to the processor 61 signal. When there is a broken tooth, the machine is shut down and an alarm is sounded. The cut-off detection unit can be used as an ultrasonic or laser sensor that can emit detection rays to the cutting teeth. The number of returns of the detection rays on the cutting teeth within one rotation of the saw disk 41 can be used to determine whether there is a broken tooth. The processor 61 may include one or more processing cores. The processor 61 uses various interfaces and lines to connect various parts of the entire server. By running or executing instructions, programs, code sets or instruction sets stored in the memory, and calling data stored in the memory, the server performs various functions and processes data. Optionally, the processor 61 may use digital signal processing (Digital Signal Processing). The processor 61 may be implemented in at least one of the following hardware forms: a central processing unit (CPU), a graphics processing unit (GPU), and a modem, wherein the CPU mainly processes the operating system, the user interface diagram, and the application program, etc.; the GPU is responsible for rendering and drawing the content to be displayed on the display screen;The modem is used to process wireless communications; it is understandable that the modem may not be integrated into the processor 61, but may be implemented by a separate chip. ;

[0045] In a preferred embodiment, see Figure 1 The operating steps of the device are as follows: S1. Start the belt drive mechanism 2 through the operation panel 6, and drive the saw disc 41 to operate through the belt drive mechanism 2; S2. Through the assembly monitoring unit 5, it can be used to monitor whether the saw disc 41 is installed properly, and the power detection unit 7 can detect the operating status of the saw disc 41, so that the staff can control the start and stop of the saw disc 41 through the operation panel 6.

[0046] In this embodiment, the staff controls the processor 61 through the operation button 62 on the operation panel 6, controls the operation of the belt drive mechanism 2 through the processor 61, and controls the saw disk 41 to cut the rails through the belt drive mechanism 2. In actual use, by assembling the monitoring unit 5 and the power detection unit 7, the operating status of the rail sawing equipment can be effectively understood, thereby effectively enhancing the stability and safety of the device during operation.

[0047] In order to better understand the present invention, the following Figures 1 to 6The technical solution of the present invention is described in detail: a belt drive mechanism 2 is arranged on the frame 1 to conveniently drive the entire saw disk 41 to rotate, and an assembly monitoring unit 5 is arranged on the frame 1 to monitor whether the saw disk 41 is properly installed, and an operation panel 6 is used to facilitate the start and stop of the device, and a power detection unit 7 is arranged to monitor the operating state of the saw disk 41 to avoid dangerous situations, thereby greatly improving the safety and stability of the device during use. The operating principle of the rail sawing machine is to provide power through an internal motor and transmit the power to the saw disk 41 through gears, belts and hydraulic transmission structures to ensure efficient cutting. The outer edge of the saw disk 41 forms cutting teeth, and the cutting teeth are made of a material with a harderness than that of the rail (such as the above-mentioned metal oxides, ceramic oxides or metal ceramic oxides). There is almost no wear during the cutting operation, and gaps are formed between the cutting teeth. The gap is conducive to chip removal, increasing the contact area with the air and dissipating heat, thereby avoiding the accumulation of chips at the cutting position, which is not conducive to the cutting operation. Good heat dissipation performance is conducive to reducing the temperature of the saw disk 41 and the rail, avoiding the decrease in strength, rigidity or hardness of the saw disk 41 as the temperature increases, and also avoiding the change in crystal phase structure (such as bluing) caused by excessive temperature increase when the rail is cut, which leads to a decrease in mechanical properties. The saw disk 41 is made of wear-resistant material (such as high-hardness metal oxides, ceramic oxides or metal ceramic oxides). As the cutting proceeds, the outer diameter of the saw disk 41 does not decrease substantially. The broken tooth detection sensor 73 is installed on the bracket to detect whether the cutting teeth are broken; the signal output end of the broken tooth detection sensor 73 is connected to the signal of the processor 61. When there is a broken tooth, the machine is shut down and an alarm is given; whether there is a broken tooth is determined by detecting the number of returns of the detection ray on the cutting tooth within one rotation of the saw disk 41;By arranging the first handle 31 and the second handle 32 on the frame 1, the portability of the whole device is improved, and it is convenient for the staff to hold it during the cutting process. By arranging the first temperature sensor 81 on the frame 1 to monitor the external environment temperature, and transmitting the temperature of the first temperature sensor 81 to the processor 61, the processor 61 analyzes the temperature data, and starts the electric heating wire 92 to heat the inside of the sleeve 91, and the second temperature sensor 82 is used to detect the internal temperature of the sleeve 91, so that the work efficiency of the staff in winter can be improved, and the first handle 31 and the second handle 32 can be prevented from being overheated. In order to prevent the occurrence of frozen hands, the stability of the staff during use is improved, thereby ensuring the cutting efficiency. The pressure sensor 51 is installed on the clamping device or flange of the saw disk 41 to ensure that the clamping force can be accurately measured, and a suitable pressure sensor 51 is selected to ensure that its range and accuracy meet the requirements. The pressure sensor 51 selected in this application is zero-calibrated under no-load conditions to ensure accurate sensor readings, and full-scale calibration is performed under known loads to ensure sensor linearity. The pressure sensor 51 is connected to the current sampling circuit 63 in the processor 61 to monitor the clamping force in real time, and according to the device According to the equipment requirements, the upper and lower limit thresholds of the clamping force are set in the processor 61, and the clamping force data is monitored in real time to ensure that it is within the set range. When the clamping force exceeds the threshold, the system automatically alarms, and the warning light 532 and the speaker 531 give a double alarm, prompting to check the installation status of the saw disk 41, and record the clamping force data through the processor 61 to facilitate subsequent analysis and troubleshooting. Monitoring reports are generated regularly to evaluate the installation status of the saw disk 41 and the operation of the equipment. The pressure sensor 51 and the data acquisition system are checked regularly to ensure their normal operation. The installation status of the saw disk 41 is adjusted according to the monitoring results to ensure that the clamping force is within a reasonable range. The infrared The sensor 52 is arranged outside the frame 1, and is used to cooperate with the speed detection sensor 71 to detect the speed of the saw disk 41, wherein a reflective mark is attached to the saw disk 41, and the reflective mark on the saw disk 41 is measured by the infrared light emitted by the infrared sensor 52, and finally the reflected light when the mark passes through the speed sensor is detected, so as to calculate the speed of the saw disk 41. When the detection data is abnormal, the data is transmitted to the processor 61, and the speaker 531 and the warning light 532 are controlled by the processor 61 to perform a double warning, so as to facilitate the staff to quickly stop the equipment, thereby avoiding accidents. ;
