Description

Technical Field

[0001] This utility model relates to the field of industrial material transportation equipment technology, specifically an industrial-grade unloading vehicle with an overload warning system. Background Technology

[0002] Traditional industrial unloading vehicles lack precise load monitoring methods, making it difficult for operators to accurately know the vehicle's actual load. This easily leads to overloading, which reduces the vehicle's stability and can cause serious accidents such as rollovers, threatening the lives of operators. Prolonged overloading puts excessive stress on critical components such as the frame, drive system, and conveyor belt. The frame may deform or crack; the motor and reducer of the drive system are prone to overheating and accelerated wear due to overload; and the conveyor belt ages and breaks down faster. This increases the frequency and cost of equipment maintenance, significantly shortening its lifespan. Without real-time load data feedback, the scheduling and management of unloading vehicles lack a scientific basis. This often results in vehicles running empty underload, wasting transportation resources, or waiting to unload overloaded, affecting subsequent operations and reducing the efficiency of the entire industrial material transportation process, failing to meet the demands of high-efficiency production. Furthermore, most existing unloading vehicles are not equipped with comprehensive overload warning systems. When the actual load approaches or exceeds the rated load, operators cannot obtain timely warning information and cannot take measures in advance to avoid dangerous situations, which does not meet the requirements of modern industrial safety production for intelligent and automated equipment.

[0003] Therefore, it is necessary to design an industrial-grade unloading vehicle with an overload warning system to solve the problems mentioned above. Utility Model Content

[0014] As a preferred embodiment of this utility model, the inner wall of the receiving funnel is made of ceramic-coated wear-resistant material with a coating thickness of 3mm, which can effectively reduce the wear of the material on the inner wall of the funnel and extend the service life of the receiving funnel; a maintenance platform is also provided on the periphery of the receiving funnel for maintenance.

[0015] As a preferred embodiment of this utility model, a warning light is provided on the outside of the unloading vehicle body. When the vehicle controller determines that the unloading vehicle is in an overload state, the warning light flashes at a frequency of 60 times / minute and the light color is red to serve as a warning.

[0027] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0028] An industrial-grade unloading vehicle with an overload warning system includes a lower travel track 1 and an unloading vehicle body 2 above the travel track 1. A frame 3 is installed at the bottom of the unloading vehicle body 2. A support seat 4 is fixedly installed on one side of the upper part of the frame 3. A receiving hopper 5 is installed above the support seat 4. An unloading conveyor belt 6 is fixedly installed on the other side of the upper part of the frame 3. A chute 7 is opened on the side of the receiving hopper 5 at one end above the unloading conveyor belt 6. A conveyor belt drive motor 8 is connected to the upper part of the side of the unloading conveyor belt 6 to drive its operation. A travel drive device 9 is installed between the bottom of the frame 3 and the travel track 1. The travel drive device 9 rotates on the travel track 1. A high-precision pressure sensor 10 is also installed between the frame 3 and the travel drive device 9. An on-board controller 11 for controlling the unloading vehicle body 2 is fixedly installed on the side end of the unloading vehicle body 2.

[0029] Specifically, the walking drive device 9 includes a walking drive motor, a reducer, and a walking wheel. The shafts of the walking drive motor and the reducer are connected by a coupling. The shafts of the walking drive motor and the reducer are connected to the input end of the walking wheel. A reducer controller 12 is also electrically connected to the reducer, and a motor controller 13 is also electrically connected to the walking drive motor.

[0030] The vehicle controller 11 is equipped with a voice prompt device 111, which is electrically connected to the pressure sensor 10, the reducer controller 12, and the motor controller 13. The voice prompt device 111 can issue three different voice prompts, including "approaching overload", "overload threshold reached" and "overload danger", and the voice volume can be adjusted in the range of 60dB-80dB.

[0031] Specifically, the pressure sensor 10 has a range of 0-50 tons and an accuracy of ±0.2%FS. It can accurately collect the pressure data borne by the frame 3 in real time and transmit the data to the vehicle controller 11. The vehicle controller 11 has a built-in ARM Cortex-A9 processor with a computing speed of 800MIPS. It has data processing, analysis and decision-making functions and can determine whether the unloading vehicle is overloaded based on the data from the pressure sensor 10.

[0032] Specifically, the reducer controller 12 has a speed adjustment function, which can adjust the output speed of the reducer within the range of 5r / min-30r / min according to the instructions of the vehicle controller 11.

[0033] Specifically, the conveying speed of the unloading conveyor belt 6 can be adjusted within the range of 0.5m / s-2m / s via the on-board controller 11, and the surface of the conveyor belt is provided with anti-slip texture with a texture depth of 2mm to prevent the material from slipping during the conveying process.

[0034] Specifically, the inner wall of the receiving funnel 5 is made of ceramic-coated wear-resistant material with a coating thickness of 3mm, which can effectively reduce the wear of the material on the inner wall of the funnel and extend the service life of the receiving funnel; a maintenance platform 14 is also provided on the periphery of the receiving funnel 5 for maintenance.

[0035] Specifically, a warning light is installed on the outside of the unloading vehicle body 2. When the on-board controller 11 determines that the unloading vehicle is in an overload state, the warning light flashes at a frequency of 60 times / minute and the light color is red to serve as a warning.

[0036] The working process of this utility model is as follows: When using this industrial-grade unloading vehicle with an overload warning system, the material first enters the receiving hopper 5 through the chute 7. The bearing seat 4 supports the receiving hopper 5 to stably receive the material. Subsequently, the conveyor belt drive motor 8 starts, driving the unloading conveyor belt 6 to operate at an adjustable speed of 0.5m / s-2m / s, conveying the material to the designated position. The 2mm deep anti-slip texture on the surface of the conveyor belt prevents the material from slipping. The travel drive motor in the travel drive device 9 is connected to the reducer through a coupling, driving the travel wheels to rotate on the travel track 1. The reducer controller 12 adjusts the reducer output speed within the range of 5r / min-30r / min according to the instructions of the vehicle controller 11, controlling the travel speed of the unloading vehicle.

[0037] The high-precision pressure sensor 10 (range 0-50 tons, accuracy ±0.2%FS) collects the pressure data borne by the frame 3 in real time and transmits it to the vehicle controller 11; the vehicle controller 11 has a built-in ARM Cortex-A9 processor (processing speed 800MIPS) to analyze and process the data from the pressure sensor 10 and determine whether the unloading vehicle is overloaded.

[0038] If the load is close to overload, the voice prompt 111 will issue a "close to overload" voice prompt (volume 60dB-80dB), and at the same time the warning light on the outside of the unloading vehicle 2 will flash as a warning.

[0039] If the overload threshold has been reached, the voice prompt 111 will issue a voice prompt that "the overload threshold has been reached", and the vehicle controller 11 will instruct the reducer controller 12 to reduce the travel speed of the unloading vehicle.

[0040] If overloaded, the voice prompt 111 will issue a "Danger of overload" voice prompt, and the warning light will flash red at a frequency of 60 times / minute. The on-board controller 11 can further control the unloading vehicle to stop running or restrict some functions.

[0041] The maintenance platform 14 surrounding the receiving hopper 5 allows staff to inspect and maintain the receiving hopper 5 and related components. Its inner wall has a 3mm thick ceramic coating for wear resistance, which reduces material wear and extends the service life of the equipment.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
