Description

Technical Field

[0001] The invention relates to the technical field of rail maintenance, and in particular to a self-propelled repairing and grinding device for rail maintenance. Background Art

[0002] With the development of the global economy, railway transportation has played an increasingly important role in the transportation of goods and passengers. Modern railways require trains to be able to run at high speeds and heavy loads. Such high-speed and heavy-load operating conditions place extremely high demands on the smoothness and surface quality of rails. Minor surface defects on rails, such as wave wear and fatigue cracks on the rail head surface, will produce strong vibrations and noise when trains pass at high speeds, affecting the ride comfort of the trains. At the same time, these defects will also increase the dynamic action between wheels and rails, aggravate the wear of rails and wheels, and shorten their service life.

[0003] At present, in traditional rail maintenance grinding equipment, the equipment is prone to deviation when moving along the rails. The deviation will cause the equipment to be unable to accurately maintain and grind the rails, thus affecting the maintenance effect and resulting in poor grinding quality. In addition, the rails often have certain slope changes and bends during the laying process. The poor adaptability of the equipment to the curved parts will lead to poor contact with the rail surface, and the grinding block cannot maintain stable contact with the rail surface, resulting in local over-grinding or insufficient grinding, affecting the repair quality of the rails. Deviation or poor contact status will lead to omission or duplication of maintenance work, thereby reducing efficiency and increasing costs, making the equipment less practical.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. The present invention sets guide mechanisms on both sides of the vehicle body, utilizes guide wheels to contact the side walls of the rails, and automatically places the equipment in the middle position between the rails under the balance of spring elastic force. The interaction between the guide wheels and the rails ensures that the equipment always moves along the direction of the rails to avoid left and right deviations or deviations from the track, providing precise guidance for subsequent maintenance operations. The first rotary electric cylinder and the second rotary electric cylinder are connected to the second guide rod through the auxiliary rod to achieve synchronous movement, so that the grinding wheel and the electromagnetic ultrasonic probe can move accordingly with the slope change, bending, etc. of the rails, maintain a suitable contact state with the surface of the rails, and ensure the quality of grinding and flaw detection.

[0021] 2. The present invention drives the equipment to move through the crawler mechanism, and combines with the telescopic electric cylinder to adjust the vehicle body height, so that the equipment can always maintain the appropriate position corresponding to the rail, avoiding abnormal operation or equipment damage due to height problems. At the same time, the bidirectional auger can clean foreign objects on the sleepers, provide a flat travel path for the equipment, reduce the risk of derailment and damage, and avoid foreign objects affecting the walking mechanism, ensuring that the equipment moves smoothly and at a uniform speed along the rail.

[0022] 3. The present invention provides a blower and other devices. Before grinding, the blower first blows air to clean the surface of the rail to remove dust, debris and other dirt, which is beneficial for the grinding wheel to better contact the real surface of the rail, improve the grinding accuracy, reduce the resistance caused by dirt during grinding, and enable the grinding wheel to work in a stable state and at an appropriate speed, thereby increasing the grinding speed and shortening the grinding time. During the grinding process, the blower continues to work to blow away the grinding chips and take away the heat, further ensuring the grinding quality and cooling the rail.

[0023] 4. The present invention monitors the displacement of the guide rod in real time by setting a displacement sensor. Before the equipment starts grinding, it determines whether the vehicle body has risen to an appropriate height based on the detection signal of the displacement sensor. During the movement of the vehicle body, when abnormal displacement of the guide rod or failure of the pressure sensor is detected, the signal can be fed back to the control assembly in time, and the control assembly sends corresponding information to the maintenance personnel accordingly, which is convenient for repair and recovery of the equipment or timely handling of rail problems, effectively avoiding more serious hidden dangers of failure.

[0024] 5. The present invention adopts batteries as the main power source, combines photovoltaic panels to generate electricity to supplement power, and can use guide wheels to guide the power in the rail track circuit into the battery, thereby realizing a diversified and stable energy supply method, reducing dependence on a single energy source, and ensuring continuous operation of the equipment.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figures 1 to 7A self-propelled repair and grinding device for rail maintenance includes a group of rails 1 and a body 2. A control assembly 5 is arranged on the top of the body 2. The control assembly 5 is fixedly connected to an antenna 51. The control assembly 5 receives and sends signals through the antenna 51. A walking mechanism 7 is arranged at the bottom of the body 2. The walking mechanism 7 includes a moving frame, a crawler mechanism 73 and a crawler motor 74. The crawler motor 74 is fixedly installed on the moving frame. The crawler mechanism 73 is arranged at the bottom of the moving frame. The body 2 is located at the top of the moving frame. The output shaft of the crawler motor 74 is fixedly connected to the crawler mechanism 73 (this is a prior art and will not be repeated here). The entire device is driven to move by the crawler mechanism 73. The crawler operates at the expected speed and force, which helps the device to move smoothly and at a uniform speed. The four corners of the body 2 are respectively fixedly installed with telescopic electric cylinders 21, and the bottom of the telescopic electric cylinder 21 is fixedly connected to the walking mechanism 7. The telescopic electric cylinder 21 adjusts the height of the body 2 by telescoping, so that the device can always maintain a suitable position with the rails. 1, to ensure that subsequent grinding, repair and other operations can accurately act on the surface of the rail 1, and there will be no problems such as inadequate operation or damage to the equipment due to height mismatch. A two-way auger 71 is rotatably connected to the mobile frame, and the two-way auger 71 is laterally distributed on one side of the forward direction of the vehicle body 2. An auger motor 72 is fixedly installed on the mobile frame, and the output shaft of the auger motor 72 is connected to the two-way auger 71 through a belt mechanism 75. The auger motor 72 drives the two-way auger 71 to rotate through the belt mechanism 75. The bottom of the two-way auger 71 is flush with the bottom of the crawler mechanism 73. During the forward movement of the equipment, foreign objects such as gravel and dirt on the sleepers will hinder the movement of the equipment. The setting of the two-way auger 71 can push these foreign objects to both sides of the equipment, providing a relatively flat travel path for the equipment, ensuring that the equipment can move smoothly along the rail 1, reducing the risk of derailment or damage of the equipment during travel, and at the same time avoiding foreign objects entering the walking mechanism 7 of the equipment to cause the crawler to get stuck, aggravated wear and other problems.

[0035] Guide mechanisms are respectively arranged on both sides of the vehicle body 2, and the two sets of guide mechanisms correspond to the two rails 1 respectively. The guide mechanisms include a guide rod 1 218, a guide rod 219 and a guide rod 3 220. The guide rod 219 is located between the guide rod 1 218 and the guide rod 3 220. The guide rod 1 218, the guide rod 219 and the guide rod 3 220 are all slidably connected with the vehicle body 2. A guide wheel 1 26 is fixedly installed on the end of the guide rod 1 218 away from the vehicle body 2, a guide wheel 27 is fixedly installed on the end of the guide rod 219 away from the vehicle body 2, and a guide wheel 3 28 is fixedly installed on the end of the guide rod 3 220 away from the vehicle body 2. Springs 25 are respectively arranged on the outer walls of the guide rod 1 218, the guide rod 219 and the guide rod 3 220, and the two ends of the spring 25 are respectively fixedly connected with the vehicle body 2 and the corresponding guide wheels. The equipment is placed on the two The guide wheels in the two sets of guide mechanisms are in contact with the side walls of the rails 1 on the corresponding sides respectively. When the guide wheels on both sides are in close contact with the sides of the rails 1, the equipment will automatically adjust to the middle position between a set of rails 1 under the elastic force balance of the springs 25 on both sides. Because the elastic forces of the springs 25 on both sides of the equipment are equal and symmetrical, the equipment will be "pulled" to the balanced position between the rails 1 on both sides, ensuring that the equipment moves along the center position of the rails 1, providing precise guidance for subsequent equipment movement and maintenance operations, and avoiding the equipment from deviating from the rails 1 or deviating to one side during movement. During the movement of the equipment, the guide wheels are in close contact with the sides of the rails 1. Through the interaction between the guide wheels and the rails 1, it can be ensured that the equipment always moves along the direction of the rails 1, avoiding the equipment from deviating left or right or deviating from the track.

[0036] Six displacement sensors 6 are arranged inside the vehicle body 2. The six displacement sensors 6 are divided into two groups. The two groups of displacement sensors 6 correspond to the two groups of guide mechanisms respectively. The guide rod 1 218, the guide rod 219 and the guide rod 3 220 respectively penetrate the corresponding displacement sensors 6 and are slidably connected with the displacement sensors 6. The displacement sensors 6 detect the displacement of the corresponding guide rods in real time. Two groups of rotation mechanisms are arranged on the top of the vehicle body 2. The two groups of rotation mechanisms correspond to the two groups of guide mechanisms respectively. The rotation mechanisms include a rotary electric cylinder 1 223 and a rotary electric cylinder 224. 24, the interior of the vehicle body 2 is provided with an inner cavity 225, the rotary electric cylinder 1 223 and the rotary electric cylinder 2 24 are slidably connected in the inner cavity 225, and the inner cavity 225 passes through the top of the vehicle body 2, the top output end of the rotary electric cylinder 1 223 is fixedly installed with a turntable 1 29, and the top output end of the rotary electric cylinder 2 24 is fixedly installed with a turntable 210, the turntable 1 29 and the turntable 2 210 are both located at the top of the vehicle body 2, the top of the turntable 1 29 is rotatably connected with an L-shaped rotating rod 1 211, and the top of the turntable 1 29 is fixedly installed with an extension rod 211. The cylinder rod of the telescopic electric cylinder 24 is fixedly connected to the side wall of the rotating rod 211, and the rotating rod 211 is provided with a grinding assembly and a blowing assembly. The grinding assembly includes a telescopic electric cylinder 22 fixedly installed at the end of the rotating rod 211 away from the turntable 29, and a fixing plate is fixedly installed at the bottom output end of the telescopic electric cylinder 22, and a driving motor 215 is fixedly installed on the fixing plate. The output end of the driving motor 215 is fixedly connected to a grinding wheel 213, and the blowing assembly includes a hair dryer 217 fixedly installed on the rotating rod 211, and a blowing The fan 217 is located on the side of the grinding wheel 213 close to the turntable 29, the side wall of the rotating rod 211 is provided with an air inlet 216, the air inlet 216 is connected to the blower 217, the side wall of the turntable 210 is fixedly installed with a rotating rod 212, the rotating rod 212 is provided with a probe assembly, the probe assembly includes a telescopic electric cylinder 3 23 fixedly installed on the rotating rod 212, the telescopic electric cylinder 3 23 is located at one end of the rotating rod 212 away from the turntable 210, and the bottom output end of the telescopic electric cylinder 3 23 is fixedly installed with an electromagnetic ultrasonic probe 214.

[0037] Before starting grinding, the equipment stops moving for adjustment, and the telescopic electric cylinder 21 lifts the vehicle body 2 upward. The top inclined surface of the guide wheel contacts the side inclined surface of the rail 1. As the vehicle body 2 rises, due to the interaction of the inclined surfaces, the guide wheel will be subjected to a lateral force, and this lateral force will cause the guide rod to move backward. The function of the displacement sensor 6 is to monitor the displacement of the guide rod. When the displacement sensor 6 detects that the guide rod has reached a preset displacement position (i.e., feedback of a specific signal), the control system receives this signal and determines that the vehicle body 2 has risen to a suitable height, thereby issuing an instruction to stop the telescopic electric cylinder 21, and the vehicle body 2 also stops rising, ensuring that the vehicle body 2 is at a suitable height position, ensuring that subsequent grinding and other operations can be performed at the correct position. During the forward movement of the equipment, when a group of displacement sensors 6 detects that the displacements of the guide rod 1 218, the guide rod 2 219 and the guide rod 3 220 in the guide mechanism all exceed the set value, the control assembly 5 determines that the rail 1 is severely bent here based on the detection data, and immediately sends the position information to the maintenance personnel for repair and adjustment. After the body 2 is in position, the telescopic electric cylinder 4 24 retracts the cylinder rod to drive the L-shaped rotating rod 1 211 to rotate and stand up, and then the rotating electric cylinder 1 223 and the rotating electric cylinder 2 224 respectively drive the turntable 1 29 and the turntable 2 210 to rotate, so that the rotating rod 1 211 and the rotating rod 212 are both perpendicular to the rail 1. The hair dryer 217 first blows air to the rail 1, which can effectively remove dust, debris and other dirt on the surface of the rail 1, so that the subsequent grinding wheel 213 can better contact the real surface of the rail 1 during grinding, improve the grinding accuracy, and ensure the geometric shape and The surface quality meets the requirements. The grinding wheel 213 does not need to overcome the resistance caused by dirt during rotational grinding, and can work in a more stable state and at a suitable rotation speed, which helps to increase the grinding speed and reduce the grinding time. During the grinding process, the hair dryer 217 continues to work to blow the grinding chips away from the grinding area to prevent the grinding chips from adhering to the surface of the rail 1 again and affecting the grinding quality. The friction between the grinding wheel 213 and the rail 1 will generate a lot of heat. The airflow blown by the hair dryer 217 can take away part of the heat and play a role in cooling the rail 1.

[0038] The telescopic electric cylinder 22 and the telescopic electric cylinder 3 23 are started, so that the electromagnetic ultrasonic probe 214 and the grinding wheel 213 are in contact with the rail 1, and the driving motor 215 drives the grinding wheel 213 to rotate. The telescopic electric cylinder 22 and the telescopic electric cylinder 3 23 are both provided with pressure sensors, which can accurately detect the pressure inside the telescopic electric cylinder 22 and the telescopic electric cylinder 3 23. When the pressure reaches the set value, it means that the contact force between the grinding wheel 213 and the electromagnetic ultrasonic probe 214 and the rail 1 is appropriate. The appropriate contact force can ensure that the grinding wheel 213 grinds the surface of the rail 1 evenly and stably. The electromagnetic ultrasonic probe 214 can better couple with the rail 1, effectively transmit and receive ultrasonic signals to the rail 1, and more accurately detect defects inside the rail 1, such as cracks, inclusions, etc. When the electromagnetic ultrasonic probe 214 detects that the defects such as cracks and pores in the rail 1 exceed the set value during the forward movement of the equipment, the position information is immediately sent to the maintenance personnel through the antenna 51 to notify the maintenance personnel to come for processing.

[0039] The rotary electric cylinder 1 223 and the rotary electric cylinder 2 224 in the rotating mechanism are distributed on both sides of the corresponding side guide rod 219. The rotary electric cylinder 1 223 and the corresponding side guide rod 219 are fixedly connected with the auxiliary rod 1 221, and the rotary electric cylinder 2 224 and the corresponding side guide rod 219 are fixedly connected with the auxiliary rod 222. The primary function of the auxiliary rod 1 221 and the auxiliary rod 2 222 is to make the rotary electric cylinder 1 223 and the rotary electric cylinder 2 224 realize synchronous movement with the guide rod 2 219. When the equipment runs on the rail 1 When the guide wheel 27 contacts the rail 1, due to the changes in the surface conditions of the rail 1 (such as unevenness, curves, etc.), the guide wheel 27 will be displaced through the guide rod 219, and the auxiliary rod 1 221 and the auxiliary rod 222 can synchronously drive the rotary electric cylinder 1 223 and the rotary electric cylinder 2 224 to move, so that they move with the guide rod 219, thereby ensuring that the grinding wheel 213 and the electromagnetic ultrasonic probe 214 connected thereto can also adapt to the slope changes of the rail 1 and maintain a suitable contact state with the surface of the rail 1.

[0040] A mounting plate 41 is fixedly installed on the side of the vehicle body 2 away from the bidirectional auger 71, and a battery 3 and a photovoltaic panel 4 are fixedly installed on the top of the mounting plate 41. The battery 3 provides power for the operation of the equipment, and the photovoltaic panel 4 generates photovoltaic power and stores the power in the battery 3. Two inner cavities 226 are arranged inside the vehicle body 2, and the two inner cavities 226 correspond to the guide rods 3 220 on the corresponding sides respectively. One end of the guide rod 3 220 away from the guide wheel 3 28 is fixedly connected to the battery 3 with a wire 227, and the wire 227 is located in the corresponding inner cavity 226. The guide wheel 3 28 contacts the rail 1 to guide the power in the track circuit of the rail 1 into the guide rod 3 220, and the wire 227 continuously inputs the power in the track circuit into the battery 3 for storage, so that the energy supply of the equipment is more stable and reliable, reducing the dependence on a single energy source and ensuring the continuous operation of the equipment.

[0041] In the present invention, the whole set of equipment is composed of a body 2 and a traveling mechanism 7. The body 2 and the traveling mechanism 7 are connected together by four telescopic electric cylinders 21 on the body 2, and the body 2 is raised and lowered by the telescopic electric cylinder 21. The height of the whole set of equipment is designed to be lower than the height of the rail 1, so that the equipment can better adapt to the spatial layout with a track structure and reduce the impact on the environment around the track. The whole set of equipment is guided by guide wheels located on both sides of the body 2. The guide wheels are connected to the corresponding guide rods and are kept rebound by springs 25. The guide rods pass through the corresponding displacement sensors 6 in the body 2. The displacement sensors 6 monitor the displacement of the guide rods in real time. The staff puts the equipment between the rails 1 and the springs 25 provide a Under the rebound force, each guide wheel contacts the side of the rail 1 and automatically places the equipment in the middle position between a group of rails 1. The antenna 51 receives and sends signals for the control assembly 5. The staff sends a forward command, and the track motor 74 drives the track mechanism 73 to rotate. Driven by the walking mechanism 7, the grinding equipment moves forward in the direction of the rail 1 under the guidance of the guide wheel. At the same time, the auger motor 72 is energized and drives the two-way auger 71 to rotate through the belt mechanism 75. The bottom of the two-way auger 71 is basically flush with the bottom of the track mechanism 73. The rotating two-way auger 71 on the way forward pushes foreign objects such as gravel and dirt on the sleepers in the forward direction to both sides of the equipment to prevent foreign objects from causing bumps or tilting of the equipment during movement, thereby ensuring smooth movement of the equipment.

[0042] The staff sends a grinding instruction, the equipment stops immediately and rises upward through the telescopic electric cylinder 1 21 until the top inclined surface of the guide wheel contacts the side inclined surface of the rail 1, causing the guide rod to move backward, and the displacement sensor 6 feedbacks a signal, the vehicle body 2 stops rising, first the telescopic electric cylinder 4 24 retracts the cylinder rod and drives the L-shaped rotating rod 1 211 to rotate and stand up, then the rotating electric cylinder 1 223 and the rotating electric cylinder 2 224 respectively drive the turntable 1 29 and the turntable 2 210 to rotate, so that the rotating rod 1 211 and the rotating rod 2 212 are both perpendicular to the rail 1, the telescopic electric cylinder 2 22 and the telescopic electric cylinder 3 23 on the rotating rod 1 211 and the rotating rod 2 212 extend the cylinder rod, and at the same time the hair dryer 217 blows strong air to the rail 1 to sweep away the dust and other dirt on the rail 1, and the driving motor 215 drives the grinding wheel 213 to rotate. When the pressure in the telescopic electric cylinder 22 and the telescopic electric cylinder 3 23 is After the sensor detects that the set pressure has been reached, the control assembly 5 determines that the grinding wheel 213 and the electromagnetic ultrasonic probe 214 are in contact with the rail 1 with an appropriate force, and the equipment immediately moves forward at a uniform speed. According to the real-time monitoring of the pressure sensors in the telescopic electric cylinder 22 and the telescopic electric cylinder 3 23, the grinding wheel 213 and the electromagnetic ultrasonic probe 214 are adjusted to maintain appropriate force contact with the rail 1. As the equipment moves forward, the grinding wheel 213 performs preventive grinding on the rail 1, and the hair dryer 217 blows the grinding waste to the outside of the rail 1 while cooling the surface of the rail 1 being ground. The electromagnetic ultrasonic probe 214 detects the internal situation of the passing rail 1 through the surface of the ground rail 1. When it is detected that the defects such as cracks and pores in the rail 1 exceed the set value, the position information is immediately sent to the maintenance personnel through the antenna 51 to notify the maintenance personnel to come for processing.

[0043] The guide rod 219 is connected with the auxiliary rod 1 221 and the auxiliary rod 222, the auxiliary rod 1 221 is connected with the rotary electric cylinder 1 223, the auxiliary rod 222 is connected with the rotary electric cylinder 2 224, the guide wheel 27 moves along the side wall of the rail 1 and drives the guide rod 219 to move forward and backward following the bending of the rail 1, and the rotary electric cylinder 1 223 and the rotary electric cylinder 2 224 move forward and backward in the inner cavity 1 225 accordingly with the forward and backward movement of the guide rod 219, so as to ensure that the grinding wheel 213 and the electromagnetic ultrasonic probe 214 can move with the deformation of the rail 1 to ensure the quality of grinding and flaw detection. When the displacement sensor 6 detects that the displacement of the three guide rods on one side exceeds the set value , the control assembly 5 determines that the rail 1 is severely bent at this point, and immediately sends the position information to the maintenance personnel for processing. By detecting the internal flaws of the rail 1 and providing feedback on the bending, the use quality of the rail 1 is guaranteed to prevent the rail 1 from being broken or bent when in use. The hidden dangers of causing severe jolting or even derailment of the train are eliminated during the preventive grinding stage, which greatly reduces the workload of the maintenance personnel. If the pressure sensor of the telescopic electric cylinder 1 21 or the telescopic electric cylinder 22 or the telescopic electric cylinder 3 23 fails and causes the cylinder rod to continue to extend, the equipment will be lifted up and cause the guide wheel to come off the rail 1. The displacement sensor 6 feeds back a signal to the maintenance personnel to recover the equipment for repair, which greatly reduces the workload of the maintenance personnel.
