Description

Technical Field

[0001] This invention relates to the field of rail scale weighing technology, and more specifically, to a long-platform dynamic rail scale. Background Technology

[0002] A rail scale is a weighing instrument used to weigh the load of railway freight cars. There are three types: static rail scales, dynamic rail scales, and light rail scales. Dynamic rail scales are used to weigh the load of railway freight cars while they are in motion. They are widely used in factories, mines, metallurgy, foreign trade, and railway departments to weigh bulk cargo in freight cars.

[0003] Existing dynamic rail scales use a broken rail installation method, which involves dividing the guide rail and then adapting the load cells to make direct contact with the railway freight cars to detect and calculate their weight. However, broken rail dynamic rail scales are very inconvenient to install, use, disassemble, and maintain. They require significant modifications to the guide rails, occupy a large area, are not flexible in use, and provide limited weighing data with inaccurate results. To address these issues, our technicians have developed a long-platform dynamic rail scale. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a long-platform dynamic track scale.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A long-platform dynamic track scale includes two track bodies and a set of sleepers. The sleepers are installed on the outside of the two track bodies. Two connecting boxes are snapped onto the outside of the sleepers. Pressure detection components are provided inside the connecting boxes. Active fixing components are provided on the outside of the connecting boxes. T-shaped bars are installed inside the track bodies. Weighing sensors are installed inside the T-shaped bars. Driven fixing components are provided on the outside of the T-shaped bars.

[0007] As a further description of the above technical solution:

[0008] The active fixing component includes a first piston tube, a hydraulic rod, a first piston plate, and a guide tube. The first piston tube is installed on the outside of the connecting box. The hydraulic rod is installed on one end of the first piston tube. One end of the hydraulic rod is fixedly connected to the outside of the first piston plate. The first piston plate is slidably connected to the inside of the first piston tube. One end of the guide tube passes through and is fixedly connected to the inside of the first piston tube. The other end of the guide tube passes through and is fixedly connected to the inside of the connecting box.

[0009] As a further description of the above technical solution:

[0010] The driven fixing component includes a connecting pipe, a second piston pipe, a second piston plate, and an abutment plate. One end of the second piston pipe is fixedly connected to the outside of the T-shaped strip. The second piston plate is slidably connected to the inside of the second piston pipe. The abutment plate is installed on the outside of the second piston plate. The outside of the abutment plate is in close contact with the outside of the track body. One end of the connecting pipe passes through and is fixedly connected to the inside of the first piston pipe. The other end of the connecting pipe passes through and is fixedly connected to the inside of the second piston pipe.

[0011] As a further description of the above technical solution:

[0012] The pressure detection component includes two pressure blocks, two pressure sensors, four sliding rods, and four springs. The pressure blocks are fixedly connected to the inside of the connecting box. The pressure sensors are installed inside the pressure blocks. One end of each sliding rod passes through and is slidably connected to the outside of the connecting box. The other end of each sliding rod contacts the outside of the pressure block. The springs are sleeved on the middle of the sliding rods. One end of each spring is fixedly connected to the middle of the sliding rods. The other end of each spring is fixedly connected to the outside of the connecting box. The outside of each pressure block contacts the outside of the sleeper.

[0013] As a further description of the above technical solution:

[0014] The connection between the sliding rod and the connecting box is sealed.

[0015] As a further description of the above technical solution:

[0016] The track body has a convex groove inside, and the T-shaped strip is engaged with the inside of the convex groove.

[0017] As a further description of the above technical solution:

[0018] The connection box is equipped with a sealing frame and an anti-slip frame, with the anti-slip frame located on the outside of the sealing frame.

[0019] As a further description of the above technical solution:

[0020] Laser rangefinders are installed on both the front and back of the connector box.

[0021] Compared with the prior art, the advantages of this invention are:

[0022] (1) In this scheme, the connecting box is attached to a suitable sleeper, and then the T-shaped strip is placed inside the convex groove. During the sliding process, the gas between the connecting box and the sleeper can be extracted through the conduit, so that the connecting box and the sleeper are in a vacuum state, achieving the effect of adsorption and fixation. The connecting box is installed on the outside of the sleeper. At the same time, during the movement of the first piston plate towards the front, it abuts against the main body of the track. At this time, the abutting plate abuts against the main body of the track, and the T-shaped strip abuts against the convex groove, thereby achieving a better fixing effect.

[0023] (2) In this scheme, the weighing sensor will directly contact the railway freight car transport wheel to detect and record the weight data. At the same time, the main body of the track will cause the sleeper to deform. When the sleeper deforms downward, the sliding rod will be pressed against the ground. Then, the sliding rod will move upward according to the deformation, so that the top of the sliding rod will contact the pressure block, and the pressure sensor will detect the pressure value and record it. The greater the weight of the railway freight car, the stronger the pressure. At the same time, the detection value of the laser distance sensor will also change. Similarly, the greater the weight of the railway freight car, the greater the displacement value. Then, the pressure data and displacement of the sleeper will be detected and recorded. Combined with the obtained weight data, it is convenient for staff to conduct centralized analysis to obtain accurate weight data of the railway freight car. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention;

[0033] Please see Figures 1-6 In this invention, a long-platform dynamic track scale includes two track bodies 1 and a set of sleepers 2. The sleepers 2 are installed on the outside of the two track bodies 1. Two connecting boxes 3 are snapped onto the outside of the sleepers 2. Pressure detection components 4 are provided inside the connecting boxes 3. Active fixing components 5 are provided on the outside of the connecting boxes 3. T-shaped bars 6 are installed inside the track bodies 1. Weighing sensors 7 are installed inside the T-shaped bars 6. Driven fixing components 8 are provided on the outside of the T-shaped bars 6.

[0034] The track body 1 has a convex groove 9 inside, and the T-shaped strip 6 is engaged with the inside of the convex groove 9.

[0035] Laser rangefinders 12 are installed on both the front and back of the connector box 3.

[0036] In this invention, when weighing is required, the operator can attach the connecting box 3 to the appropriate sleeper 2, then place the T-shaped strip 6 inside the convex groove 9. Next, the active fixing component 5 is used to install the connecting box 3 onto the outside of the sleeper 2. Simultaneously, the driven fixing component 8 is driven, causing the T-shaped strip 6 to be stably attached to the inside of the convex groove 9. When the railway freight car passes through the area between the track body 1 and the sleeper 2, the weighing sensor 7 will directly contact the transport wheel of the railway freight car to detect and record the weight data. At the same time, the track body 1 will cause the sleeper 2 to deform. During this deformation, the pressure detection component 4 will detect the pressure on the sleeper 2. The greater the weight of the railway freight car, the stronger the pressure. Simultaneously, the detection value of the laser ranging sensor 12 also changes. Similarly, the greater the weight of the railway freight car, the greater the displacement value. The pressure data and displacement of the sleeper 2 will then be detected and recorded. Combined with the obtained weight data, this allows the operator to perform centralized analysis to obtain accurate weight data for the railway freight car.

[0037] Please see Figures 1-3The active fixing component 5 includes a first piston tube 51, a hydraulic rod 52, a first piston plate 53, and a conduit 54. The first piston tube 51 is installed on the outside of the connecting box 3. The hydraulic rod 52 is installed on one end of the first piston tube 51. One end of the hydraulic rod 52 is fixedly connected to the outside of the first piston plate 53. The first piston plate 53 is slidably connected to the inside of the first piston tube 51. One end of the conduit 54 passes through and is fixedly connected to the inside of the first piston tube 51. The other end of the conduit 54 passes through and is fixedly connected to the inside of the connecting box 3.

[0038] In this invention, the hydraulic rod 52 is used to operate, which allows the first piston plate 53 to slide forward inside the first piston tube 51. During the sliding process, the gas between the connecting box 3 and the sleeper 2 can be extracted through the conduit 54, so that the connecting box 3 and the sleeper 2 are in a vacuum state, achieving the effect of adsorption and fixation.

[0039] Please see Figures 1-3 The driven fixing member 8 includes a connecting pipe 81, a second piston pipe 82, a second piston plate 83, and a contact plate 84. One end of the second piston pipe 82 is fixedly connected to the outside of the T-shaped strip 6. The second piston plate 83 is slidably connected to the inside of the second piston pipe 82. The contact plate 84 is installed to the outside of the second piston plate 83. The outside of the contact plate 84 is in close contact with the outside of the track body 1. One end of the connecting pipe 81 passes through and is fixedly connected to the inside of the first piston pipe 51. The other end of the connecting pipe 81 passes through and is fixedly connected to the inside of the second piston pipe 82.

[0040] In this invention, during the forward movement of the first piston plate 53, the gas inside the first piston tube 51 is simultaneously squeezed into the interior of the second piston tube 82 through the connecting pipe 81, thereby using the gas to push the second piston plate 83. Then, the abutment plate 84 on the outer side of the second piston plate 83 is driven downward to abut against the track body 1. At this time, the abutment plate 84 abuts against the track body 1, and the T-shaped strip 6 abuts against the convex groove 9, thereby completing the fixation.

[0041] Please see Figures 1-4 The pressure detection component 4 includes two pressure blocks 41, two pressure sensors 42, four sliding rods 43, and four springs 44. The pressure blocks 41 are fixedly connected to the inside of the connecting box 3. The pressure sensors 42 are installed inside the pressure blocks 41. One end of the sliding rod 43 passes through and slides to the outside of the connecting box 3. The other end of the sliding rod 43 contacts the outside of the pressure blocks 41. The springs 44 are sleeved on the middle of the sliding rods 43. One end of the springs 44 is fixedly connected to the middle of the sliding rods 43. The other end of the springs 44 is fixedly connected to the outside of the connecting box 3. The outside of the pressure blocks 41 contacts the outside of the sleeper 2.

[0042] In this invention, when the sleeper 2 deforms downwards, the sliding rod 43 will press against the ground, and then the sliding rod 43 will move upwards according to the deformation, so that the top of the sliding rod 43 will come into contact with the pressure block 41, and the pressure sensor 42 will detect the pressure value and record it. When the railway freight car leaves, the sleeper 2 deforms back to its original position. At this time, the elastic force of the spring 44 will be used to drive the sliding rod 43 to move back to its original position, which will facilitate the next pressure detection.

[0043] Please see Figures 1-4 The connection between the sliding rod 43 and the connecting box 3 is sealed.

[0044] In this invention, the connection between the sliding rod 43 and the connecting box 3 is sealed to ensure the airtightness between the connecting box 3 and the sleeper 2, thereby ensuring the installation and fixing effect of the entire device.

[0045] Please see Figures 1-5 The connecting box 3 is equipped with a sealing frame 10 and an anti-slip frame 11, with the anti-slip frame 11 located on the outside of the sealing frame 10.

[0046] In this invention, the use of a sealing frame 10 and an anti-slip frame 11 ensures that the connecting box 3 has good airtightness and anti-slip properties during use, thus guaranteeing the installation effect.

[0047] It should be noted that all the devices in this application are common devices on the market, and can be selected according to the needs of specific use. The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection. Those skilled in the art can easily implement it. It belongs to the prior art and will not be described in detail.

[0048] Working principle: When weighing is required, the operator can attach the connecting box 3 to the appropriate sleeper 2, then place the T-shaped strip 6 into the convex groove 9. Next, using the active fixing component 5 and the hydraulic rod 52, the first piston plate 53 slides forward inside the first piston tube 51. During this sliding process, the air between the connecting box 3 and the sleeper 2 is extracted through the conduit 54, creating a vacuum between them, achieving adsorption and fixation. The connecting box 3 is then installed on the outside of the sleeper 2. The sealing frame 10 and anti-slip frame 11 ensure good airtightness and anti-slip properties during use, guaranteeing the installation effect. The moving fixing member 8 will be driven. During the forward movement of the first piston plate 53, the gas inside the first piston tube 51 will be squeezed from the connecting pipe 81 into the second piston tube 82, thereby using the gas to push the second piston plate 83. Then, the abutment plate 84 on the outer side of the second piston plate 83 will be driven downward to abut against the track body 1. At this time, the abutment plate 84 abuts against the track body 1, and the T-shaped strip 6 abuts against the convex groove 9, thus completing the fixation. Subsequently, when the railway freight car passes through the area between the track body 1 and the sleeper 2, the weighing sensor 7 will directly contact the railway freight car transport wheel to detect and record the weight data. At the same time, the track body 1 will cause the sleeper 2 to deform downward. When the deformation occurs, the sliding rod 43 will press against the ground, and then move upward according to the deformation, so that the top of the sliding rod 43 contacts the pressure block 41, causing the pressure sensor 42 to detect the pressure value and record it. The greater the weight of the railway freight car, the stronger the pressure, and the detection value of the laser ranging sensor 12 will also change. Similarly, the greater the weight of the railway freight car, the greater the displacement value. Then, the pressure data and displacement of the sleeper 2 will be detected and recorded. Combined with the obtained weight data, it is convenient for staff to conduct centralized analysis to obtain the accurate weight data of the railway freight car. When the railway freight car moves away, the sleeper 2 deforms to its original position. At this time, the elastic force of the spring 44 is used to facilitate the movement of the sliding rod 43. The moving rod 43 moves to its original position to facilitate the next pressure test. When it is necessary to disassemble the connecting box 3 and the T-shaped bar 6, the operator can activate the hydraulic rod 52 to move to its original position, so that the gas in the first piston tube 51 is discharged back into the connecting box 3. At the same time, the gas in the second piston tube 82 will also be discharged back into the first piston tube 51, thereby driving the second piston plate 83 to move upward, so that the contact plate 84 is separated from the track body 1. Then the operator can remove the connecting box 3 and the T-shaped bar 6 in sequence, completing the disassembly without affecting the normal use of the track body 1. The operator can install the connecting box 3 and the T-shaped bar 6 in different positions according to the usage requirements, and the number of installations can also be selected by the operator according to the usage situation.

[0049] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
