Description

Technical Field

[0001] The invention relates to the technical field of truck scales, in particular to a flap truck scale. Background Art

[0002] Truck scales are widely used in the field of cargo weighing, especially in industrial and logistics transportation. Traditional truck scales usually consist of a flat weighing table, a weighing sensor and a display device, and weighing is performed by the pressure of the wheels on the weighing table. However, this type of truck scale has a relatively simple structure, does not have a flap function, and cannot automatically unload materials, so it has certain limitations in specific applications. Usually, when a loaded vehicle needs to be unloaded, it needs to be operated manually or with external equipment (such as a forklift or other loading and unloading tools), which increases the workload and operation time and reduces work efficiency.

[0003] In order to make up for this shortcoming, some truck scales have begun to adopt a design with a flip-plate unloading function, using a flip platform to tilt the scale to achieve automatic unloading. However, most of the existing flip-plate truck scales rely on a hydraulic jacking system to flip the platform. Although this structure can achieve the purpose of unloading, its hydraulic system structure is complex, which not only increases the manufacturing cost and maintenance difficulty, but also has the risk of hydraulic system failure during long-term use, affecting the safety and stability of the equipment. In addition, the control accuracy of the hydraulic system during the flipping process is low, which may cause the flipping to be not smooth enough, and even uneven material tilting or incomplete unloading. These defects have caused many restrictions on the actual application of the existing flip-plate truck scales, and they cannot fully meet the user's needs for efficient and safe unloading.

[0004] Therefore, the prior art urgently needs a flip-plate truck scale with a simple structure, easy operation and high safety, which can achieve smooth and automatic material unloading without relying on a complex hydraulic system, and has reliable locking and resetting functions to improve the overall operating efficiency and safety performance of the equipment. Summary of the invention

[0005] The present invention aims to solve one of the technical problems existing in the prior art or related technology.

[0006] To this end, the technical solution adopted by the present invention is: a flip-plate truck scale, including a weighing platform, a discharge platform, a flip-plate mechanism and a weighing assembly. The present invention uses an innovative design to enable the truck scale to not only perform accurate weighing but also realize automatic unloading, and has the advantages of simple structure, convenient operation and high stability.

[0007] In a possible implementation, the flap truck scale includes a weighing platform, a discharge platform, a flap mechanism and a weighing assembly, wherein the weighing assembly is in a plurality and evenly distributed on the bottom surface of the weighing platform, ensuring uniform force during weighing, improving weighing accuracy and structural stability. Side wing plates are provided on both sides of the weighing platform to help guide vehicles in and out, and ramp plates are fixedly connected at both ends of the weighing platform to provide a smooth transition when vehicles enter and exit, reducing the impact of vehicles on the platform.

[0008] In a possible implementation, the unloading platform is provided in two groups, which are located on one side of the two side wing plates respectively, and the bottom surface thereof is provided with a return spring for active connection with the surface of the side wing plate. This design allows the return spring to be stretched when the weighing platform is tilted, providing a rebound force to restore the level, which helps the platform to quickly return to its original position after unloading is completed, thereby improving work efficiency.

[0009] In a possible implementation, the flip mechanism includes a fixed seat, a tilting frame and a turning platform, wherein the tilting frame is fixedly mounted on the surface of the fixed seat and symmetrically arranged on both sides of the turning platform. The top surface of the tilting frame is provided with an arch frame and guide wings symmetrically arranged on both sides of the top surface of the arch frame. This structure ensures stability during the flipping process, while ensuring that the flipping platform moves along a fixed path, avoiding tilt or deviation during the flipping process, and improving the reliability of the equipment.

[0010] In a possible implementation, side ear seats are fixedly installed on both sides of the turning platform, and the side ear seats are slidably sleeved on the inner side of the guide wing, and the bottom surface abuts against the top surface of the arch frame. This design makes the tilting process of the turning platform smoother, effectively reduces friction through sliding connection, and prolongs the service life of the equipment.

[0011] In a possible embodiment, the bottom surface of the transfer platform is rotatably connected to an unlocking rod and a locking ear. The unlocking rod cooperates with the locking ear to realize the locking and unlocking functions of the platform, ensuring rapid unlocking when flipping is required, and rapid locking after the flipping is completed, thereby ensuring the stability of the equipment.

[0012] In a possible implementation, the weighing assembly is located on the top surface of the rotating platform, and its upper and lower ends are fixedly connected to the bottom surface of the weighing plate and the bottom surface of the rotating platform respectively. The weighing assembly includes a floating seat, a fixed plate seat, and a force strain gauge located inside the floating seat, wherein the force strain gauge is used to monitor the sinking movement of the weighing plate, and then measure the pressure on the surface of the weighing plate to achieve accurate measurement of the vehicle weight.

[0013] In a possible embodiment, the guide wing is designed in an arc shape, and the contact point of the bottom surface of the side ear seat is located at the center of the arc of the guide wing, so that the flip platform maintains smooth sliding during the tilting process, reduces tilt and error, and ensures the accuracy of the flipping operation.

[0014] In a possible embodiment, the side ear seat is in the shape of a horizontal plate, and has sliding ears at both ends for slidingly abutting against the inner side of the guide wing, ensuring that the platform always maintains the correct position during the flipping or resetting process to avoid deviation, thereby further improving the flipping stability.

[0015] In a possible implementation, the unlocking rod and the lock ear are located on the vertical center plane of the tilting frame and the weighing platform, and one end of the unlocking rod is movably connected to the surface of the lock ear to drive the lock ear to deflect to unlock or lock the platform. At the same time, the surface of the lock buckle groove is provided with a buckle groove adapted to the lock ear to ensure that the platform can be quickly locked after resetting, thereby improving safety.

[0016] In a possible implementation, a buffer shock-absorbing pad is provided between the rotating support platform and the rotating and tilting frame to buffer the impact force generated during the flipping or resetting process, reduce the wear of mechanical parts, and thus extend the service life of the equipment.

[0017] The beneficial effects achieved by the present invention are:

[0018] 1. In the present invention, the flipping function of the weighing platform is realized by setting up a flipping mechanism. The sliding connection between the side ear seat and the guide structure in the structure ensures the stability during the flipping process, and utilizes the natural center of gravity deviation effect when the car is loaded with goods to automatically deflect and overturn to realize material unloading. The structure is simple and easy to use.

[0019] 2. In the present invention, by arranging a return spring and a reset support rod on the unloading platform, when the weighing platform is tilted, the spring is stretched, and when the weighing platform is reset, it quickly returns to a horizontal state, thereby improving the reset speed and efficiency.

[0020] 3. In the present invention, through the cooperation of the unlocking rod and the lock ear, a reliable locking and unlocking function is provided to ensure stability after flipping, and it can be quickly unlocked when needed, which is convenient for the weighing platform to tip over by its own weight and quickly lock in the reset state.

[0033] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0034] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0035] A tipping truck scale provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0036] Combination Figure 1-Figure 7 As shown, a flap truck scale provided by the present invention includes a weighing platform 100, a discharge platform 200, a flap mechanism 300 and a weighing assembly 400. Among them, a plurality of weighing assemblies 400 are evenly distributed on the bottom surface of the weighing platform 100 for supporting and weighing. Side wing plates 130 are provided on both sides of the weighing platform 100 for guiding vehicles in and out, and ramp plates 120 are fixedly connected at both ends of the weighing platform 100 to provide a smooth transition of the vehicle up and down.

[0037] There are two groups of unloading platforms 200, which are respectively located on one side of the two side wing plates 130. A return spring 210 is provided on the bottom surface of each unloading platform 200 for active connection with the surface of the side wing plate 130. When the weighing plate 100 tilts, the return spring 210 is stretched to provide a restoring resilience, so that the weighing plate 100 can quickly return to a horizontal state after unloading.

[0038] The flipping mechanism 300 is mainly composed of a fixed seat 310, a tilting frame 320 and a rotating platform 340. The tilting frame 320 is fixedly mounted on the surface of the fixed seat 310 and symmetrically arranged on both sides of the rotating platform 340. An arch frame 330 is provided on the top surface of the tilting frame 320, and guide wings 321 are symmetrically arranged on both sides of the arch frame 330. Side ear seats 350 are fixedly installed on both sides of the rotating platform 340, wherein the side ear seats 350 are slidably sleeved on the inner side of the guide wings 321, and the bottom surface abuts against the top surface of the arch frame 330, to ensure the smooth movement of the weighing platform 100 during the flipping process.

[0039] During the flipping process, the bottom surface of the rotating support 340 cooperates with the unlocking rod 360 and the locking ear 341 through a rotational connection to provide the locking and unlocking functions of the flap. One end of the unlocking rod 360 is movably connected to the surface of the locking ear 341 to drive the locking ear 341 to perform a deflection movement to unlock or lock the flap mechanism. The surface of the fixing seat 310 is also provided with a locking groove 311 adapted to the locking ear 341. When the locking ear 341 is reset, it is engaged with the locking groove 311 to ensure the stability of the flap mechanism during vehicle weighing.

[0040] During the implementation, when a vehicle enters and stops on the weighing plate 100, the weighing assembly 400 monitors the pressure exerted by the vehicle on the weighing plate 100 in real time through the force strain gauge 430, thereby measuring the weight of the vehicle. The force strain gauge 430 is installed on the inner side of the fixed plate 420, and can detect the sinking movement of the weighing plate 100 to ensure the accuracy of weighing.

[0041] When unloading is required, the flap mechanism 300 is unlocked by controlling the unlocking rod 360 and the locking ear 341 to release the locked state. The side ear seat 350 slides on the guide deflection of the guide wing 321, driving the weighing plate 100 to tilt to one side. Under the effect of the center of gravity shift of the vehicle load, the material slides into the unloading platform 200 through the tilted weighing plate 100, completing automatic unloading. After unloading is completed, the return spring 210 quickly restores the weighing plate 100 to a horizontal state through its return spring force and the lifting of the reset support rod 500 on the corresponding side. At the same time, the unlocking rod 360 and the locking ear 341 in the flap mechanism cooperate to lock again to ensure that the weighing plate 100 is stable and immovable after resetting.

[0042] The present invention realizes automatic weighing and efficient unloading operations of vehicles by optimizing the flap mechanism, locking device and weighing assembly. It has the advantages of simple structure, convenient operation, accurate weighing and rapid unloading, and can be widely used in weighing and unloading scenarios in the fields of industry, logistics and so on.

[0043] The working principle and use process of the present invention:

[0044] The present invention realizes the functions of vehicle weighing and automatic unloading by designing a flip-plate truck scale. Its core working principle is based on the synergy between the flip-plate mechanism 300 and the weighing assembly 400. When the vehicle drives onto the weighing platform 100, the force strain gauge 430 in the weighing assembly 400 will sense the pressure change on the weighing platform 100 and measure the vehicle weight in real time. At the same time, the weighing platform 100 can be flipped through the flip-plate mechanism 300, thereby automatically tipping the material by utilizing the center of gravity offset of the vehicle itself to complete the unloading operation.

[0045] The main principles include:

[0046] Flip function: The sliding connection between the side ear seat 350 and the guide wing 321 in the flip mechanism 300 enables the weighing platform 100 to tilt smoothly under certain conditions. When the vehicle is loaded with goods, due to the certain gravity center shift effect of the vehicle loaded with goods, the flip mechanism 300 naturally overturns with the gravity center shift, and the materials slide out of the unloading platform 200.

[0047] Locking and unlocking mechanism: During the flipping or resetting process, the cooperation between the unlocking lever 360 and the locking ear 341 provides a reliable locking function to ensure the stability of the weighing platform 100 during the weighing process. When the vehicle is on the surface of the weighing platform 100, the locking ear 341 and the locking groove 311 are connected to keep the weighing platform 100 in a horizontal state; when tilting is required, the unlocking lever 360 can be quickly unlocked to allow the weighing platform 100 to deflect.

[0048] Quick reset function: Through the return spring 210 set on the bottom surface of the unloading platform 200, after the weighing platform 100 tilts and completes unloading, the return spring 210 is stretched to provide resilience, and through the lifting of the reset support rod 500, the weighing platform 100 is quickly restored to a horizontal state. At the same time, the unlocking mechanism is automatically locked after the reset is completed to ensure the stability of the platform.

[0049] Usage process:

[0050] Weighing preparation: The vehicle drives onto the flip-plate truck scale, and the wheels are limited by the limit assembly 110 to ensure that the vehicle is in a stable position. At this time, the weighing assembly 400 starts to work, and the force strain gauge 430 monitors the sinking movement of the scale plate 100 to measure the weight of the vehicle.

[0051] Vehicle weighing: After the vehicle comes to a complete stop, the weighing assembly 400 accurately measures the weight of the vehicle, and the relevant weight data is transmitted to the weighing system through the force strain gauge 430 for recording and display.

[0052] Flip unloading:

[0053] When unloading is required, the flap mechanism 300 starts to work, the side ear seat 350 slides inside the guide wing 321, and the weighing plate 100 gradually tilts to one side. With the help of the center of gravity offset of the vehicle loading, the material slides from the surface of the weighing plate 100 to the unloading platform 200, completing the unloading process. The designed side wing plate 130 ensures that the material is discharged smoothly during the unloading process.

[0054] Reset Lockout:

[0055] After the unloading is completed, the return spring 210 is stretched and begins to contract, so that the tilted weighing platform 100 gradually returns to a horizontal state.

[0056] As the weighing platform 100 is reset, the unlocking rod 360 and the locking ear 341 are automatically matched and locked to ensure the stability of the weighing platform 100 after it is reset.

[0057] After resetting, the vehicle can safely leave the weighing area, completing the entire operation process.

[0058] Reuse: After being reset, the flip-plate truck scale can continue to weigh or unload the next vehicle. The system is stable and efficient and can be reused.

[0059] Through the above working principle and process, the present invention realizes automatic weighing and efficient unloading of vehicles, reduces manual intervention, improves work efficiency, and the entire unloading process is smooth and safe, the equipment structure is simple, and the maintenance cost is low.
