Description

Technical Field

[0001] This invention relates to the field of metallurgy, specifically to a fastening device for a railway track pressure plate bolt and its method of use. Background Technology

[0002] Crane tracks in the metallurgical industry, also known as metallurgical crane tracks or metallurgical plant tracks, are the key operating carriers for heavy equipment such as bridge cranes and casting cranes in metallurgical workshops. They operate in harsh environments, requiring them to withstand extreme conditions such as high temperatures, high dust levels, and strong corrosion, and typically bear extremely demanding workloads. During the operation of heavy equipment, the crane tracks not only bear enormous vertical loads but also significant horizontal forces. These dynamic loads can easily cause lateral or longitudinal displacement of the crane tracks, gradually leading to shifting or loosening. If the accumulated displacement exceeds the allowable range, it will seriously affect the safety and stability of the equipment operation.

[0003] To ensure the reliable stability of the railway tracks, clamping bolts are commonly used to secure the tracks to the track beam foundation. While this method effectively suppresses track displacement, it has limitations in practical applications: the vibrations from the continuous operation of heavy equipment can cause the clamping bolts to gradually loosen, creating safety hazards; and frequent bolt tightening is necessary to maintain the fixation. Furthermore, traditional bolt tightening requires multiple workers to perform strenuous, near-edge bending operations in the confined space on either side of the tracks, resulting in high labor intensity, harsh working conditions, low efficiency, and safety risks such as falls from heights. Secondly, manual bolt tightening suffers from insufficient precision, easily leading to over-torque tightening and tensile deformation of the bolts, causing secondary problems such as bolt breakage and further threatening the operational safety of the equipment. Summary of the Invention

[0004] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a fastening device for the pressure plate bolts of the railway track and a method for using it, which can automatically fasten the pressure plate bolts of the railway track, improve the accuracy of bolt fastening operations, and reduce the labor intensity of workers.

[0005] To achieve the above objectives, the present invention provides a fastening device for a rail plate bolt, comprising a fastening mechanism and a railcar for moving on the rail. The fastening mechanism includes a vertical moving structure, a fastening motor, and a bolt fastening head. Vertical moving structures are provided on both sides of the railcar. The fastening motor is fixedly connected to the vertical moving structure, and the bolt fastening head is rotatably connected to the fastening motor.

[0006] Furthermore, the railcar includes a control mechanism, a drive motor, and rail wheels that can fit onto the rail. The vertical moving structure, the fastening motor, and the drive motor are all electrically connected to the control mechanism. The rail wheels are located at the bottom of the railcar and are connected to the drive motor.

[0007] Furthermore, the railcar is made of aluminum alloy.

[0008] Furthermore, the track wheel is made of carbon fiber.

[0009] Furthermore, the track vehicle is also equipped with a detection mechanism, which includes a vision sensor for detecting the position of the pressure plate bolt. The vision sensor is mounted on the track vehicle and close to the bolt fastening head, and is connected to the control mechanism.

[0010] Furthermore, the detection mechanism also includes a torque sensor for detecting the torque of the pressure plate bolt. The torque sensor is disposed on the bolt fastening head and is connected to the control mechanism.

[0011] Furthermore, the railcar is also equipped with a support mechanism, which includes a support frame fixedly connected to the railcar, and two support outer wheels are connected to the support frame.

[0012] Furthermore, the supporting outer wheel includes a wear-resistant rubber roller.

[0013] Furthermore, the railcar is also equipped with a tensioning mechanism, which includes a double-rod hydraulic cylinder fixedly connected to the railcar. Each end of the double-rod hydraulic cylinder is connected to a connecting rod, and tensioning rollers that can fit against the side of the railcar are connected to the connecting rods.

[0014] The present invention also discloses a method for using a fastening device, which is used to fasten the aforementioned rail pressure plate bolts. The method includes the following steps:

[0015] S1. Place the railcar onto the track;

[0016] S2. Move the track vehicle to align the bolt fastening head with the pressure plate bolt;

[0017] S3. Start the vertical moving structure. The vertical moving structure drives the fastening motor and bolt fastening head to move downward, so that the bolt fastening head is fixed on the pressure plate bolt.

[0018] S4. Start the fastening motor, which drives the bolt fastening head to rotate and tightens the pressure plate bolt to the preset torque.

[0019] As described above, the fastening device for the track pressure plate bolts and its method of use of the present invention have the following beneficial effects:

[0020] By incorporating a railcar and fastening mechanism, the pressure plate bolts of the train track can be automatically tightened, reducing the labor intensity of workers and eliminating the risks associated with prolonged bending and bending near edges. The control and detection mechanisms enable the fastening device to automatically position and align the pressure plate bolts, and to automatically tighten them, improving the accuracy of the bolt tightening operation and preventing bolt breakage due to excessive torque. Furthermore, the tensioning and support mechanisms enhance the stability and usability of the railcar and fully ensure the safety of workers. Attached Figure Description

[0030] See Figures 1 to 3 This invention provides a fastening device for a rail track pressure plate bolt, comprising a fastening mechanism 1 and a railcar 2 for moving on a rail track 7. Preferably, the center of the railcar 2 is located in the central plane extending along the length of the rail track 7. The fastening mechanism 1 includes a vertical moving structure 101, a fastening motor, and a bolt fastening head 102. Vertical moving structures 101 are provided on both the left and right sides of the railcar 2, i.e., vertical moving structures 101 are provided on both sides of the rail track 7. The fastening motor is fixedly connected to the vertical moving structure 101, and the bolt fastening head 102 is rotatably connected to the fastening motor. Preferably, the fastening mechanism 1 also includes a mounting frame 103 and two lateral moving structures provided on the mounting frame 103. The mounting frame 103 is fixedly connected to the railcar 2, and the vertical moving structures 101 are located on both sides of the railcar 2. All 01 are connected to the mounting frame 103 via a lateral moving structure. Preferably, the lateral moving structure includes a slide rail on the mounting frame 103 and a pulley on the vertical moving structure 101. The lateral moving structure can drive the vertical moving structure 101 to move left and right. In other embodiments, the lateral moving structure can also adopt other structures. Preferably, the vertical moving structure 101 includes a hydraulic lifting cylinder, and a fastening motor is connected to one end of the hydraulic lifting cylinder. The hydraulic lifting cylinder can drive the fastening motor to move up and down. Preferably, the fastening motor is a servo motor, which can drive the bolt fastening head 102 to rotate. Specifically, the driver of the servo motor is adjusted according to the signal fed back by the encoder in real time. By adjusting the controller, the error between the expected and actual output can be reduced, and the torque output of the servo motor can be precisely controlled.

[0031] The basic working principle of the fastening device for the pressure plate bolt of the railway track involved in this invention is as follows: By setting up the railcar 2, the fastening device can move freely on the railway track 7. By setting the fastening mechanism 1 on the railcar 2, when the railcar 2 moves to the position of the pressure plate bolt 8, the vertical moving structure 101 can drive the fastening motor and the bolt fastening head 102 to move downward, so that the bolt fastening head 102 is fixed on the pressure plate bolt 8. When the fastening motor is started, the bolt fastening head 102 can automatically tighten the bolt, which greatly reduces the labor intensity of the workers and ensures the safety of the workers.

[0032] See Figures 1 to 3 The present invention will be further described below with reference to a specific embodiment:

[0033] In this embodiment, see Figure 1 , Figure 2 and Figure 3 As a preferred design, the railcar 2 includes a control mechanism 201, a drive motor 202, and rail wheels 203 that can fit onto the rail 7. The vertical moving structure 101, the fastening motor, and the drive motor 202 are all electrically connected to the control mechanism 201. The rail wheels 203 are located at the bottom of the railcar 2 and are connected to the drive motor 202. Preferably, the control mechanism 201 is a programmable logic controller (PLC) capable of remote and manual control. Specifically, it can control the drive motor 202 to start, stop, accelerate, and decelerate the railcar 2, control the vertical moving structure 101 to move up and down, and control the fastening motor to drive the bolt fastening head 102 to rotate, thereby tightening the pressure plate bolt 8. In other embodiments, the control mechanism 201 can also be a microcontroller. Preferably, there are two rail wheels 203, which are spaced apart.

[0034] In this embodiment, see Figure 1 , Figure 2 and Figure 3 As a preferred design, the railcar 2 is made of aluminum alloy, which has high strength, good mechanical properties, good machinability, and good corrosion resistance.

[0035] In this embodiment, see Figure 1 and Figure 3 As a preferred design, the track wheel 203 is made of carbon fiber, which has high strength, is lightweight, and has excellent fatigue resistance and chemical stability.

[0036] In this embodiment, see Figure 1 , Figure 2 and Figure 3As a preferred design, the track vehicle 2 is also equipped with a detection mechanism, which includes a vision sensor 4 for detecting the position of the pressure plate bolt 8. The vision sensor 4 is mounted on the track vehicle 2 and close to the bolt fastening head 102, and is connected to the control mechanism 201. Preferably, when the track vehicle 2 moves on the travel track 7, the vision sensor 4 can detect and position the pressure plate bolt 8. The control mechanism 201 adjusts the position of the track vehicle 2 on the travel track 7 by controlling the drive motor 202, so that the bolt fastening head 102 of the fastening mechanism 1 is aligned with the pressure plate bolt 8, that is, the center point of the bolt fastening head 102 is aligned with the center point of the pressure plate bolt 8. The control mechanism 201 controls the vertical moving structure 101 to move downward, so that the bolt fastening head 102 is fixed on the pressure plate bolt 8. The control mechanism 201 drives the bolt fastening head 102 to rotate and tighten the pressure plate bolt 8 by controlling the fastening motor. Preferably, the vision sensor 4 includes an industrial camera, which has the advantages of high resolution, high frame rate, and the ability to be used in high temperature and high dust environments.

[0037] In this embodiment, see Figure 1 , Figure 2 and Figure 3 As a preferred design, the detection mechanism also includes a torque sensor for detecting the torque of the pressure plate bolt 8. The torque sensor is mounted on the bolt fastening head 102 and is connected to the control mechanism 201. Preferably, the torque sensor can detect the torque of the pressure plate bolt 8 in real time and adjust the output torque of the fastening motor in real time through the control mechanism 201. When the torque of the pressure plate bolt 8 reaches the preset torque value, the control mechanism 201 controls the fastening motor to stop outputting and records the data.

[0038] In this embodiment, see Figure 1 , Figure 2 and Figure 3 As a preferred design, the railcar 2 is also equipped with a support mechanism 5, which includes a support frame 501 fixedly connected to the railcar 2. Two support outer wheels 502 are connected to the support frame 501. Preferably, there are two support frames 501, which are spaced apart from each other. Preferably, the two support outer wheels 502 on the support frame 501 are located on both sides of the railcar 2. The support outer wheels 502 are in contact with the ground, which can provide additional support, reduce the wear of the rail wheels 203 to a certain extent, reduce shaking, and improve the stability and ease of use of the railcar 2. Preferably, the support frame 501 is equipped with shock-absorbing springs, which can absorb impacts and reduce vibrations. They dissipate energy through elastic deformation, thereby reducing the impact of vibration and impact on the railcar 2.

[0039] In this embodiment, see Figure 1 , Figure 2 and Figure 3As a preferred design, the outer support wheel 502 includes wear-resistant rubber rollers. The elasticity of the rubber can absorb impact and vibration, avoiding damage to the railcar 2 caused by rigid contact. It also has the advantages of friction resistance, high temperature resistance, and corrosion resistance, and has a long service life.

[0040] In this embodiment, see Figure 1 , Figure 2 and Figure 3 As a preferred design, the track vehicle 2 is also equipped with a tensioning mechanism 6. The tensioning mechanism 6 includes a double-rod hydraulic cylinder fixedly connected to the track vehicle 2. Each end of the double-rod hydraulic cylinder is connected to a connecting rod 601. A tensioning roller 602 that can conform to the side of the track 7 is connected to the connecting rod 601. Specifically, each end of the double-rod hydraulic cylinder is connected to two connecting rods 601, which are located on both sides of the track 7. This allows the double-rod hydraulic cylinder to move the two connecting rods 601 together away from or towards the track 7. The connecting rods 601 and the tensioning rollers 602... The connection allows the double-rod hydraulic cylinder to drive the two tensioning rollers 602 to respectively adhere to the two sides of the traveling rail 7, and can provide a force in the range of 100-400KN·m for the two tensioning rollers 602 to adhere to the two sides of the traveling rail 7. When the railcar 2 is running on the traveling rail 7, it can avoid the railcar 2 from tipping over due to the reaction force generated when the bolts are tightened, the deformation of the traveling rail 7, the vibration of the traveling rail 7, etc., thereby preventing unsafe and unstable accidents during the tightening operation and improving the safety of the railcar 2.

[0041] See Figures 1 to 3 The present invention also discloses a method for using a fastening device, which is used to fasten the above-mentioned rail track pressure plate bolts. The method includes the following steps:

[0042] S1. Place the railcar 2 onto the train track 7;

[0043] S1.1 Attach the track wheel 203 to the top of the traveling track 7;

[0044] S1.2. The two connecting rods 601 are driven by the double-rod hydraulic cylinder, which in turn drives the two tensioning rollers 602 located on both sides of the traveling rail 7 to approach the traveling rail 7 and make the tensioning rollers 602 fit against the side of the traveling rail 7.

[0045] S2. Move the track vehicle 2 to align the bolt fastening head 102 with the pressure plate bolt 8;

[0046] S2.1 The control mechanism 201 controls the drive motor 202 to drive the track wheel 203 to rotate, so that the track car 2 moves on the track 7;

[0047] S2.2 When the railcar 2 moves on the track 7, the position of the pressure plate bolt 8 is detected and positioned by the vision sensor 4 in the detection mechanism;

[0048] S2.3. The control mechanism 201 controls the drive motor 202 to adjust the position of the railcar 2 on the track 7, so that the bolt fastening head 102 of the fastening mechanism 1 is aligned with the pressure plate bolt 8, that is, the center point of the bolt fastening head 102 is aligned with the center point of the pressure plate bolt 8.

[0049] S3. After the bolt fastening head 102 is aligned with the pressure plate bolt 8, the vertical moving structure 101 is started by the control mechanism 201. The vertical moving structure 101 drives the fastening motor and the bolt fastening head 102 to move downward, so that the bolt fastening head 102 is fixed on the pressure plate bolt 8.

[0050] S4. When the bolt fastening head 102 is fixed on the pressure plate bolt 8, the fastening motor is started by the control mechanism 201. The fastening motor drives the bolt fastening head 102 to rotate, so that the bolt fastening head 102 applies torque to the pressure plate bolt 8. That is, the bolt fastening head 102 is used to fasten the pressure plate bolt 8 and fasten the pressure plate bolt 8 to the preset torque.

[0051] S4.1 When the bolt fastening head 102 tightens the pressure plate bolt 8, the torque of the pressure plate bolt 8 is detected by the torque sensor in the detection mechanism. When the torque of the pressure plate bolt 8 reaches the preset torque value, that is, after the bolt fastening head 102 tightens the pressure plate bolt 8, the control mechanism 201 controls the fastening motor to stop outputting and records the data.

[0052] As described above, the fastening device for the track pressure plate bolts and its method of use of the present invention have the following beneficial effects:

[0053] By setting up the railcar 2 and the fastening mechanism 1, the pressure plate bolts 8 of the traveling rail 7 can be automatically tightened, reducing the labor intensity of the workers and eliminating the risks and hazards caused by workers bending over at the edge for a long time. By setting up the control mechanism 201 and the detection mechanism, on the one hand, the fastening device can automatically position and align the pressure plate bolts 8, and on the other hand, it can automatically tighten the pressure plate bolts 8, improving the accuracy of the tightening operation of the pressure plate bolts 8 and avoiding bolt breakage caused by excessive torque tightening of the pressure plate bolts 8. By setting up the tensioning mechanism 6 and the support mechanism 5, the stability and ease of use of the railcar 2 can be improved, and the safety of the workers can be fully guaranteed.

[0054] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
