Description

Technical Field

[0001] This utility model relates to the field of vehicle safety technology, and in particular to a universal integrated vehicle overload limiting device. Background Technology

[0002] With the rapid development of modern transportation, a large number of freight vehicles frequently operate on urban roads, industrial parks, warehousing and logistics centers, and key passages such as tunnels and bridges. Driven by economic benefits, some vehicles are overloaded, which not only accelerates the damage to infrastructure such as roads and bridges, but also easily leads to traffic accidents such as brake failure and vehicle rollovers, seriously threatening public transportation safety. Therefore, vehicle overload detection and restriction technologies are gradually gaining attention.

[0003] Existing overload detection methods mainly involve deploying weighbridges or axle load detection devices at key road nodes to achieve static or dynamic weighing of vehicles. These devices can obtain vehicle weight data relatively accurately, but most only have weighing and data collection functions and lack linkage control with traffic restrictions, on-site warnings, and other links. They often require manual intervention to prevent overloaded vehicles from entering specific areas, resulting in low regulatory efficiency and cumbersome operation.

[0004] On the other hand, while some road entrances or gates are equipped with simple barrier devices, these devices only serve the purpose of vehicle passage management and are not integrated with weighing systems. They cannot automatically open or close based on detection results, making it difficult to automatically intercept overloaded vehicles. Furthermore, in actual use, traditional barrier devices are prone to breakage or mechanical damage when vehicles forcibly pass through or when subjected to wind, leading to increased maintenance costs and impacting subsequent use.

[0005] To address the aforementioned issues, this invention provides a universal integrated vehicle overload limiting device that enables automatic vehicle weighing and detection, overload alarm prompts, and linkage with traffic restriction mechanisms. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a universal integrated vehicle overload limiting device.

[0007] The purpose of this utility model is to provide a universal integrated vehicle overload limiting device, comprising a portal support frame. A weighing instrument is installed on the ground in front of the portal support frame to weigh passing vehicles. The weighing instrument can be selected according to needs, and is based on existing technology, as long as it can weigh vehicles and transmit data; no technical limitations or elaborations are required. A display is installed at the upper end of the portal support frame. The weighing instrument transmits the weighed vehicle data to a controller, which displays the vehicle weight data on the display. A warning light is installed on one side of the portal support frame. When the vehicle weight data obtained by the controller does not meet the set weight value (exceeds the limit), the controller controls the warning light to illuminate, alerting relevant personnel that the vehicle is overloaded. Vehicle barrier mechanisms are symmetrically installed on the left and right sides of the portal support frame. When a vehicle is overloaded, the controller will not control the vehicle barrier mechanisms to open, allowing vehicles to pass. The weighing instrument includes a weighing instrument body, which can be equipped with a corresponding weighing instrument as needed. This instrument is based on existing technology and is designed to weigh vehicles and transmit data; no technical limitations or elaborations are required. For example, an axle load cell could be used. The weighing instrument body has symmetrically arranged ramps on its front and rear sides, allowing vehicles to easily enter the weighing instrument. The ramps are detachably connected to the weighing instrument body. Fluorescent strips are located on the left and right sides of the ramps, allowing vehicles to easily identify the markings on the equipment and guide them to the weighing instrument. The weighing instrument body also has symmetrically arranged L-shaped locking rods on its front and rear sides. A slot is provided at the bottom of the ramps, allowing the L-shaped locking rods to engage with the slots. The detachable weighing instrument body and ramps facilitate disassembly, storage, and transportation.

[0008] The weighing instrument body has handle slots on both the left and right sides, allowing for easy left and right movement of the instrument body to ensure it can weigh vehicles. The vehicle stop mechanism includes a housing with a rotating groove. A stop lever is rotatably mounted inside the housing, passing through the rotating groove. A rotating shaft is located inside the housing, and the stop lever is rotatably mounted on the shaft. A rotating cylinder is rotatably and vertically mounted on the shaft, and is fixedly connected to the stop lever. A drive mechanism is located inside the housing, driving the rotating cylinder to rotate.

[0009] A rotating cylinder two is rotatably mounted on the rotating shaft. A spiral fan blade one is mounted on the upper end of the rotating cylinder two, and a spiral fan blade two is mounted on the lower end of the rotating cylinder two. Spiral fan blade one and spiral fan blade two are mutually engaged. When the shift lever rotates 90 degrees backward without rotating spiral fan blade two, spiral fan blade one rotates 90 degrees along with the shift lever. At this time, spiral fan blade one and spiral fan blade two interact, causing spiral fan blade one to move upward (when the shift lever rotates 90 degrees, the upper end of rotating cylinder one is in contact with the retaining ring, preventing the shift lever from detaching from the rotating shaft or spiral fan blade one from detaching from spiral fan blade two). Spiral fan blade one never detaches from spiral fan blade two, allowing the shift lever to move upward. This technical solution can protect the shift lever from breakage when it rotates backward due to factors such as vehicles running through checkpoints or strong winds. The drive mechanism drives rotating cylinder two to rotate.

[0010] The drive mechanism is fixed inside the housing. A driving gear is installed at the output end of the drive mechanism, and a driven gear is fixedly installed on the outer side of the lower end of the rotating drum. The driving gear and the driven gear mesh with each other. A retaining ring is fixedly installed at the upper end of the rotating shaft. The electrical connections between the above technical solutions are existing technologies and are not intended to limit the technology; they are sufficient to achieve the functions required by this application and will not be described in detail.

[0011] Beneficial effects: This utility model has the following technical effects when used:

[0012] 1. This utility model, by installing a weighing instrument on the ground at the front end of the gate support frame, and in conjunction with a display, controller, and warning light linkage design, realizes real-time weighing and status display of vehicles before they enter the gate. It can determine overload before the vehicle enters the designated area and alert relevant personnel through audible and visual alarms, preventing overloaded vehicles from accidentally entering and improving the safety and management efficiency of gate passage.

[0013] 2. The weighing instrument features symmetrically arranged detachable ramps on both the front and rear sides, facilitating smooth vehicle loading onto the weighing platform and reducing impact wear between tires and equipment. Fluorescent strips on both sides of the ramps provide visual guidance to the driver in low-light conditions, ensuring accuracy and safety during the weighing process. The ramps are detachably connected to the weighing instrument via L-shaped levers and slots, facilitating quick on-site assembly and disassembly, as well as convenient storage and transportation, thus enhancing the device's versatility and applicability.

[0014] 3. The weighing instrument is equipped with handle slots on both the left and right sides, making it more convenient to carry or adjust the position of the equipment manually. It can be flexibly deployed in different doorways or road entrances, ensuring that the weighing position matches the vehicle passage path and enhancing the flexibility of the device.

[0015] 4. The vehicle gear lever mechanism adopts a combined structure design of housing, shaft, cylinder, and spiral fan blades. Under the action of the drive mechanism, the gear lever can rotate smoothly, and the engagement of spiral fan blades one and two achieves gear lever lifting and lowering protection. When the vehicle accidentally impacts the gear lever or encounters strong winds causing the gear lever to be subjected to backward force, the interaction between the spiral fan blades can automatically move the gear lever upward, thereby preventing the gear lever from breaking due to overload impact, significantly improving the durability and safety of the gear lever mechanism.

[0016] 5. The drive mechanism rotates the rotating drum II through the meshing of the driving gear and the driven gear, thereby achieving precise opening and closing control of the gear lever. This gear transmission method offers rapid response and stable transmission, enabling the gear lever to rise and fall quickly and reliably when vehicles pass, improving the operating efficiency and service life of the device.

[0017] 6. This application realizes a complete closed-loop management process of weighing and detection—result display—audio-visual warning—vehicle passage restriction. Overloaded vehicles are effectively blocked, and qualified vehicles are quickly released, which can not only improve the traffic order at the entrance of the road or factory area, but also effectively reduce road damage or safety hazards caused by overloading.

[0026] Example 1, asFigures 1-6 As shown, the purpose of this utility model is achieved as follows: A universal integrated vehicle overload limiting device includes a gate support frame 3. A weighing instrument 1 is installed on the ground in front of the gate support frame 3. The weighing instrument 1 is used to weigh passing vehicles. The weighing instrument 1 can be selected according to needs. It is existing technology and can realize the weighing of the vehicle and transmit data. No technical limitations or elaborations are made. A display 5 is installed at the upper end of the gate support frame 3. The weighing instrument transmits the weighed vehicle data to the controller. The controller displays the vehicle weight data through the display 5. A warning light 4 is installed on one side of the gate support frame 3. When the vehicle weighing data obtained by the controller does not meet the set weight value (exceeds), the controller controls the warning light 4 to light up to remind relevant personnel that the vehicle is overloaded. Vehicle barrier mechanisms 2 are symmetrically arranged on the left and right sides of the gate support frame 3. When the vehicle is overloaded, the controller will not control the vehicle barrier mechanism 2 to open to allow the vehicle to pass. The weighing instrument 1 includes a weighing instrument 1 body. The weighing instrument 1 body can be selected according to the corresponding weighing instrument 1 device as needed. It is a prior art device that can weigh vehicles and transmit data. No technical limitations or elaborations are made. For example, an axle load cell can be used. The weighing instrument body 101 is symmetrically provided with inclined plates 102 on the front and rear sides. The inclined plates 102 can facilitate the vehicle to enter the weighing instrument body 101. The inclined plates 102 and the weighing instrument body 101 are detachably connected. Fluorescent strips 103 are provided on the left and right sides of the inclined plates 102. The fluorescent strips 103 can facilitate the vehicle to identify the markings on the device, so as to guide the vehicle to enter the weighing instrument 1 for weighing. The weighing instrument body 101 is symmetrically provided with L-shaped locking rods 105 on the front and rear sides. The bottom of the inclined plate has a locking groove. The L-shaped locking rods 105 can be locked in the locking groove. The weighing instrument body 101 and the inclined plates are detachable, which can facilitate disassembly and storage and transportation.

[0027] The weighing instrument body has handle slots 104 on both the left and right sides, which facilitate the left and right movement of the weighing instrument body 1, ensuring that the weighing instrument body 1 can perform weighing operations on vehicles. The vehicle stop lever 2 mechanism includes a housing 6, which has a rotating groove. A stop lever 2 is rotatably mounted inside the housing 6, and the stop lever 2 rotatably passes through the rotating groove. A rotating shaft 12 is installed inside the housing 6, and the stop lever 2 is rotatably mounted on the rotating shaft 12. A rotating cylinder 10 is rotatably mounted on the rotating shaft 12 and can move up and down. The rotating cylinder 10 is fixedly connected to the stop lever. A drive mechanism 7 is installed inside the housing 6, and the drive mechanism 7 drives the rotating cylinder 10 to rotate.

[0028] A rotating cylinder 9 is rotatably mounted on the rotating shaft 12, and a spiral fan blade 14 is mounted on the upper end of the rotating cylinder 9. The lower end of the rotating drum 10 is provided with a spiral fan blade 15. The spiral fan blade 14 and the spiral fan blade 15 are mutually engaged. When the spiral fan blade 15 does not rotate and the lever 2 rotates 90 degrees backward, the spiral fan blade 14 rotates 90 degrees with the lever 2. At this time, the spiral fan blade 14 and the spiral fan blade 15 interact with each other, causing the spiral fan blade 14 to move upward (when the lever 2 rotates 90 degrees, the upper end of the rotating drum 10 is in contact with the retaining ring 13 to prevent the lever 2 from detaching from the rotating shaft 12 or the spiral fan blade 14 from detaching from the spiral fan blade 15). The spiral fan blade 14 never detaches from the spiral fan blade 15, which allows the lever 2 to move upward. This technical solution can protect the lever 2 from breaking when the lever 2 rotates backward due to some vehicles running through checkpoints or strong winds. The drive mechanism 7 drives the rotating drum 2 to rotate.

[0029] The drive mechanism 7 is fixed inside the housing 6. The output end of the drive mechanism 7 is provided with a drive gear 8, and the lower outer side of the rotating drum 9 is fixedly provided with a driven gear 11. The drive gear 8 and the driven gear 11 mesh with each other. A retaining ring 13 is fixedly provided on the upper end of the rotating shaft 12.

[0030] When in use, this application weighs the vehicle using a weighing instrument. The weighing data is transmitted to the controller, which displays the weighing data on the display 5 and identifies whether the weighing data exceeds a preset value to determine if the vehicle is overloaded. If it exceeds the preset value, the warning light 4 is activated to remind relevant personnel that the vehicle is overloaded; at the same time, the barrier 2 is not opened to restrict the vehicle from passing.

[0031] If the vehicle is not overloaded, the controller controls the drive mechanism 7 to rotate, which in turn drives the rotating drum 9 to rotate, and then drives the rotating drum 10 to rotate. The two are linked by the interlocking structure between the spiral fan blade 14 and the spiral fan blade 15; in turn, the gear lever 2 is driven to rotate backward, and then the gear lever 2 is opened to allow the vehicle to pass.
