Description

Technical Field

[0001] This utility model relates to the technical field of track weighing and measurement, specifically to a track weighing device for a ship unloader. Background Technology

[0002] A rail-mounted weighing device for a ship unloader is a device used to measure the weight the ship unloader bears while running on the rails. It typically relies on pressure sensor or load cell technology. As the ship unloader travels on the rails, its weight is transmitted to the rails through the wheels. The sensors in the rail-mounted weighing device detect changes in pressure on the rails and convert them into electrical signals. After processing and conversion, these electrical signals can accurately display the real-time weight information of the ship unloader.

[0003] In the existing technical solutions, Chinese Patent No. CN 208921258 U discloses a track scale weighing device for a bridge ship unloader: It includes a platform, with a pressure sensor installed below the platform. The pressure sensor is connected to a computer via a junction box and a data acquisition unit. The platform is installed below the outer rim of the track wheel of the bridge ship unloader, and is arranged parallel to the outside of the bridge ship unloader's track. The supporting surface of the platform is higher than the top plane of the bridge ship unloader's track. By using an independent platform as the weighing beam of the weighing device, the overall weight of the bridge ship unloader can be obtained using the pressure sensor, thereby indirectly obtaining the weight of the cargo.

[0004] The shortcomings of the existing technical solutions are as follows: the support platform is installed below the outer rim of the track wheels of the ship unloader and has a fixed structure and dimensions. Because the track wheel spacing varies significantly between different models of ship unloaders, when the track wheel spacing does not match the support platform, the weight of the ship unloader cannot be evenly transmitted to the pressure sensors. Some sensors may bear excessive pressure, while others may not bear sufficient force, resulting in an unbalanced pressure distribution and measurement errors. Utility Model Content

[0005] This utility model provides a track weighing device for a ship unloader, which can solve the problem in the prior art that the weight of the ship unloader cannot be evenly transmitted to the pressure sensor when the track wheel spacing does not match the bearing platform due to the significant difference in track wheel spacing between different models of ship unloaders.

[0006] A track-mounted weighing device for a ship unloader includes a slide rail, a slide block, a weighing platform, a pressure sensor, and a control terminal. The slide rail is horizontally arranged on the side of the ship unloader's track. The slide block is slidably connected to the slide rail. The bottom of the pressure sensor is connected to the top of the slide block. The bottom of the weighing platform is connected to the detection end of the pressure sensor. The pressure sensor is electrically connected to the control terminal. The top of the weighing platform is higher than the top of the ship unloader's track, and the top of the weighing platform is located below the outer rim of the ship unloader's track wheel. Specifically, the top of the slide rail has a horizontal groove and a slot, and the bottom of the slide block is fixedly provided with a horizontal slider that slidably engages with the horizontal groove.

[0007] As a further embodiment of this utility model: an adjustment assembly for adjusting the position of the slide block is provided within the horizontal slide groove. The adjustment assembly includes an adjustment screw, which is rotatably mounted horizontally within the horizontal slide groove. An adjustment screw hole is provided on the side of the horizontal slide block for threaded connection with the adjustment screw. The adjustment assembly also includes an adjustment motor, which is fixedly mounted within the groove. The output end of the adjustment motor is coaxially and fixedly connected to the adjustment screw, and the adjustment motor is electrically connected to a control terminal.

[0008] As a further embodiment of this utility model: a dustproof component is provided on the top of the slide rail. The dustproof component includes an accordion-style guide rail protective cover, which is fitted into the groove opening of the horizontal slide groove. One end of the accordion-style guide rail protective cover is connected to the slide rail, and the other end is connected to the slide block. The dustproof component also includes a dustproof cover, which is fitted into the groove opening. A slot is formed on the side of the slot, and a locking block that cooperates with the slot is fixedly provided on the side of the dustproof cover.

[0009] As a further embodiment of this invention: a plurality of vertical sleeves arranged in a matrix are fixedly installed on the top of the slide block, and a plurality of vertical inserts that slide in cooperation with the corresponding vertical sleeves are fixedly installed on the bottom of the weighing platform. Both ends of the weighing platform are provided with transition slopes, and the lowest point of the transition slopes is lower than the top of the unloader's track. A plurality of pressure sensors are provided and arranged in a matrix on the top of the slide block.

[0010] The advantages of this utility model compared to the prior art are:

[0011] By sliding the slide block and the slide rail, the position of the weighing platform can be quickly and easily adjusted to accommodate the differences in the track wheel spacing of different ship unloader models. Whether the ship unloader has a narrow or wide track wheel spacing, it ensures that the track wheels are accurately positioned directly above the weighing platform, allowing the weight of the ship unloader to be evenly transferred to the pressure sensor. This avoids measurement errors caused by unbalanced pressure distribution and significantly improves the versatility and applicability of the weighing device.

Detailed Implementation

[0022] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0023] First Embodiment

[0024] Please see Figures 1 to 6As shown, a track-mounted weighing device for a ship unloader includes a slide rail 1, a slide block 2, a weighing platform 3, a pressure sensor 4, and a control terminal 5. The slide rail 1 is horizontally arranged on the side of the track 7 of the ship unloader 6. The slide block 2 is slidably connected to the slide rail 1. The bottom of the pressure sensor 4 is connected to the top of the slide block 2. The bottom of the weighing platform 3 is connected to the detection end of the pressure sensor 4. The pressure sensor 4 is electrically connected to the control terminal 5. The top of the weighing platform 3 is higher than the top of the track 7 of the ship unloader 6, and the top of the weighing platform 3 is located below the outer rim of the wheel of the track 7 of the ship unloader 6. Specifically, the top of the slide rail 1 has a horizontal groove 8 and a slot 9, and the bottom of the slide block 2 is fixedly provided with a horizontal slider 10 that is slidably connected to the horizontal groove 8.

[0025] The slide rail 1 is horizontally positioned on the side of the track 7 of the unloader 6. The horizontal slider 10 at the bottom of the slide block 2 slides in conjunction with the horizontal groove 8 at the top of the slide rail 1. This structure allows the slide block 2 to move flexibly horizontally on the slide rail 1. When unloaders 6 of different models and with varying wheel spacing on the track 7 are running on the track 7, the position of the slide block 2 on the slide rail 1 can be adjusted according to the actual wheel spacing of the track 7 of the unloader 6.

[0026] After adjustment, during the operation of the unloader 6, the track wheel 7 passes over the weighing platform 3, and the weight of the unloader 6 is transferred to the weighing platform 3 via the track wheel 7. The weighing platform 3, under pressure, transmits the force to the pressure sensor 4 below. The pressure sensor 4 deforms under the force and converts the pressure into an electrical signal according to its physical properties. This electrical signal is transmitted to the control terminal 5 via a line. The control terminal 5 performs a series of processes on the received electrical signal, including amplification, filtering, and analog-to-digital conversion. Based on a pre-set algorithm and calibration parameters, it converts the electrical signal into a corresponding weight value, which is then displayed, recorded, or further analyzed, thereby achieving accurate measurement of the weight of the unloader 6.

[0027] By sliding the slide block 2 and the slide rail 1, the position of the weighing platform 3 can be quickly and conveniently adjusted to accommodate the differences in the wheel spacing of the rails 7 of different models of ship unloaders 6. Whether the wheel spacing of the rails 7 is narrow or wide, it ensures that the rails 7 are accurately positioned directly above the weighing platform 3, allowing the weight of the ship unloader 6 to be evenly transferred to the pressure sensor 4. This avoids measurement errors caused by unbalanced pressure distribution and significantly improves the versatility and applicability of the weighing device.

[0028] Second Embodiment

[0029] Based on the first embodiment, an adjustment assembly for adjusting the position of the slide block 2 is provided in the horizontal slide groove 8. The adjustment assembly includes an adjustment screw 11, which is rotatably disposed in the horizontal slide groove 8 in a horizontal state. The side of the horizontal slider 10 has an adjustment screw hole that is threadedly connected to the adjustment screw 11. The adjustment assembly also includes an adjustment motor 12, which is fixedly disposed in the slot 9. The output end of the adjustment motor 12 is coaxially fixedly connected to the adjustment screw 11, and the adjustment motor 12 is electrically connected to the control terminal 5.

[0030] When the position of slide 2 needs to be adjusted, the operator can input a command on the control terminal 5 to start the adjusting motor 12. The adjusting motor 12 drives the adjusting screw 11 to rotate. According to the principle of thread transmission, the horizontal slider 10, which is threaded with the adjusting screw 11, will drive slide 2 to move precisely horizontally within the horizontal groove 8 until the weighing platform 3 is adjusted to a position that matches the wheel spacing of the unloader 6 track 7.

[0031] Third Embodiment

[0032] Based on the first embodiment, a dustproof component is provided on the top of the slide rail 1. The dustproof component includes an accordion-style guide rail protective cover 13, which is fitted at the opening of the horizontal slide groove 8. One end of the accordion-style guide rail protective cover 13 is connected to the slide rail 1, and the other end is connected to the slide block 2. As the slide block 2 moves on the slide rail 1, the accordion-style guide rail protective cover 13 can extend and deform to always cover the opening of the horizontal slide groove 8. The dustproof component also includes a dustproof cover 14, which is fitted at the opening of the slot 9. A slot 15 is provided on the side of the slot 9, and a locking block 16 that cooperates with the slot 15 is fixedly provided on the side of the dustproof cover 14. The dustproof cover 14 is installed at the opening of the slot 9 through the cooperation of the side locking block 16 and the side locking slot 15 of the slot 9, thereby sealing the slot 9. In port environments, there is a lot of dust and debris. During the operation of the weighing device on the 6 rails 7 of the unloader, the bellows-type guide rail protective cover 13 can effectively block dust and debris from entering the horizontal slide 8, preventing them from affecting the sliding fit between the slide block 2 and the slide rail 1; the dust cover 14 prevents the components in the slot 9 from being contaminated by dust and interfered with by debris, ensuring the normal operation of each component of the device.

[0033] By incorporating dustproof components, the environmental adaptability and service life of the weighing device on the 6-railway 7 of the ship unloader are significantly improved. This effectively reduces the corrosion and wear of internal components by dust and debris, lowers the probability of jamming or damage due to component contamination, and reduces equipment maintenance frequency and costs. Simultaneously, it ensures smooth sliding of the slide block 2 on the slide rail 1 and normal operation of the adjustment components, maintaining the stability and reliability of the weighing device and enabling it to operate stably for extended periods in harsh port environments.

[0034] Fourth embodiment

[0035] Based on the first embodiment, a plurality of vertical sleeves 17 arranged in a matrix are fixedly installed on the top of the slide block 2, and a plurality of vertical inserts 18 that slide in cooperation with the corresponding vertical sleeves 17 are fixedly installed on the bottom of the weighing platform 3, providing guidance and limiting for the weighing platform 3, ensuring that the weighing platform 3 moves only in the vertical direction when subjected to force, and avoiding deviation. Both ends of the weighing platform 3 are provided with transition slopes 19, and the lowest point of the transition slopes 19 is lower than the top of the track 7 of the unloader 6. When the track 7 wheel of the unloader 6 passes over the weighing platform 3, the weight is transferred to the weighing platform 3 with the transition slopes 19 through the track 7 wheel. The transition slopes 19 guide the track 7 wheel to smoothly transition to the plane of the weighing platform 3, reducing the impact between the track 7 wheel and the weighing platform 3. A plurality of pressure sensors 4 are provided and arranged in a matrix on the top of the slide block 2. The pressure sensors 4 collectively bear the pressure transmitted by the weighing platform 3, convert the pressure into an electrical signal and transmit it to the control terminal 5 for processing.

[0036] The cooperation of the vertical sleeve 17 and the vertical insertion rod 18 enhances the stability and anti-deviation capability of the weighing platform 3, ensuring the accuracy of the force direction of the pressure sensor 4 and further improving the accuracy of weighing measurement. The transition slope 19 at both ends of the weighing platform 3 effectively reduces the impact force at the moment of contact between the track wheel 7 and the weighing platform 3, reducing equipment wear, extending the service life of the weighing device, and also reducing measurement errors caused by impact. The matrix arrangement of multiple pressure sensors 4 can sense pressure more evenly, improving the reliability and accuracy of weighing data and providing strong support for the precise measurement of cargo loading and unloading in ports.

[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
