Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment, and specifically relates to an unmanned weighbridge. Background Technology

[0002] A weighbridge is a heavy-duty weighing device used to measure the weight of vehicles or goods. It typically consists of a weighing platform, sensors, a display instrument, and connecting cables. Widely used in logistics, mining, ports, warehousing, and other locations requiring precise weighing, it can quickly and accurately measure the total weight of vehicles or goods. The weighbridge works by using sensors beneath the weighing platform to detect pressure changes, converting the weight signal into an electrical signal, which is then processed and displayed by the display instrument. However, weighbridges without expansion mechanisms have significant drawbacks in terms of upgrades, primarily in terms of insufficient flexibility and high cost. Firstly, due to the lack of modular design, the size and load-bearing capacity of these weighbridges are fixed, making them unable to be flexibly adjusted according to business needs. When it is necessary to increase weighing capacity or expand the weighing range, the entire weighbridge system must be replaced, resulting in high upgrade costs. Therefore, we aim to design an unmanned weighbridge to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an unmanned weighbridge to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: an unmanned weighbridge, comprising: a base, wherein the base is provided with a splicing mechanism for adjusting the weighbridge's load-bearing capacity and expanding the weighbridge's size, and vehicle identification mechanisms for automatic weighing are provided on the front and rear sides of the base.

[0005] The splicing mechanism includes a weighing platform one and a weighing platform two, which are located inside the base. Support legs are fixedly connected to the lower surfaces of both the weighing platform one and the weighing platform two. A weighing sensor is provided at the lower end of each support leg, and the weighing sensor is located inside the base.

[0006] The splicing mechanism also includes an expansion component, which includes an expansion platform one and an expansion platform two. Both expansion platforms one and two are fixedly connected to the front of a splicing block. By setting up the splicing mechanism, modules can be replaced as needed, the load-bearing capacity can be flexibly adjusted, and the entire weighbridge can be replaced without replacing it.

[0007] In a preferred embodiment, the weighing platform one and the weighing platform two are connected by screws, with a nut screwed onto the right end of the screw. The right side surface of the support leg of the weighing platform two is elastically connected to the nut by a spring. By setting the spring, the spring force is used to apply pressure to the nut to prevent the nut from loosening due to vibrations caused by the vehicle passing by.

[0008] In a preferred embodiment, the rear sides of both the first and second expansion platforms are also connected by screws.

[0009] In a preferred embodiment, internal threads are embedded in the left and right ends and the front and rear sides of the base. The left end of the weighing platform one and the right end of the weighing platform two are fixedly connected to the base by bolts and internal threads.

[0010] As a preferred embodiment, the rear sides of the weighing platform one and the weighing platform two are provided with splicing grooves for sliding engagement with the splicing blocks. By setting expansion components, the size of the weighbridge can be expanded at any time according to business needs, which facilitates the overall system upgrade.

[0011] As a preferred embodiment, protective railings are fixedly installed on the front and rear sides of the weighing platform one and the weighing platform two.

[0012] In a preferred embodiment, the vehicle identification mechanism includes a mounting plate, which is fixedly connected to the front and rear sides of the right end of the base. A support cylinder is fixedly connected to the mounting plate, and a gantry is slidably sleeved inside the support cylinder. The gantry is equipped with a vehicle identification monitoring system for identifying vehicles. By setting up the vehicle identification mechanism and the barrier gate control system, unauthorized vehicles can be effectively prevented from entering, thus enhancing site security.

[0013] In a preferred embodiment, the left end of the base is provided with a barrier system to prevent unauthorized vehicles from entering, and the rear side of the left end of the base is provided with a road barrier to prevent vehicles from accidentally entering before the weighbridge is extended.

[0014] In a preferred embodiment, the mounting plate is also provided with a lifting cylinder. The telescopic end of the lifting cylinder is fixedly connected to the gantry frame. An electric telescopic rod is provided on the outside of the support cylinder. The telescopic end of the electric telescopic rod slides through the inside of the support cylinder and its left end slides into the inside of the gantry frame. By setting the telescopic end of the electric telescopic rod to limit the movement of the gantry frame, the risk of the gantry frame falling accidentally is reduced.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. By setting up a modular splicing structure and using screws to splice the weighing platform one and weighing platform two, modules can be replaced as needed to upgrade the load-bearing capacity and improve the flexibility of the weighbridge. At the same time, by setting up expansion platform one and expansion platform two, the size of the weighbridge can be expanded at any time according to business needs, which facilitates the overall upgrade of the weighbridge without replacing the entire weighbridge and reduces upgrade costs.

[0017] 2. By setting up a vehicle identification system, vehicle identification and barrier gate control can effectively prevent unauthorized vehicles from entering, enhance site security, and reduce reliance on operators. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1 to 6 This utility model provides a technical solution: an unmanned weighbridge, including: a base 1, a splicing mechanism 2 for adjusting the weighbridge's load-bearing capacity and expanding its size, and vehicle identification mechanisms 3 for automatic weighing on the front and rear sides of the base 1.

[0031] The splicing mechanism 2 includes a weighing platform 1 21 and a weighing platform 22. The weighing platform 1 21 and the weighing platform 22 are located inside the base 1. The lower surfaces of the weighing platform 1 21 and the weighing platform 22 are fixedly connected to support feet 23. The lower end of the support feet 23 is provided with a weighing sensor, which is located inside the base 1.

[0032] The splicing mechanism 2 also includes an expansion component 28, which includes an expansion platform 1 281 and an expansion platform 282. The front sides of both expansion platform 1 281 and expansion platform 282 are fixedly connected to splicing blocks 283. By setting up the splicing mechanism 2, modules can be replaced as needed, the load-bearing capacity can be flexibly adjusted, and the entire weighbridge can be replaced without replacing it.

[0033] Weighing platform 1 21 and weighing platform 22 are connected by screws 24. A nut is screwed onto the right end of the screw 24. The right side surface of the support leg 23 of weighing platform 22 is elastically connected to the nut by a spring 25. By setting the spring 25, the elastic force of the spring 25 is used to apply pressure to the nut to prevent the nut from loosening due to vibration generated by the vehicle passing by.

[0034] The rear sides of expansion platform 1 281 and expansion platform 2 282 are also connected by screws 24.

[0035] The base 1 has internal threads embedded in the left and right ends and the front and rear sides. The left end of the weighing platform 1 and the right end of the weighing platform 22 are fixedly connected to the base 1 by bolts and internal threads.

[0036] The rear sides of weighing platform 1 21 and weighing platform 22 are provided with splicing grooves 26 for sliding engagement with splicing block 283. By setting expansion components 28, the size of the weighbridge can be expanded at any time according to business needs, which facilitates the overall system upgrade.

[0037] Protective railings 27 are fixedly installed on the front and rear sides of weighing platform 1 21 and weighing platform 22.

[0038] The vehicle identification mechanism 3 includes a mounting plate 31, which is fixedly connected to the front and rear sides of the right end of the base 1. A support cylinder 32 is fixedly connected to the mounting plate 31. A gantry frame 33 is slidably sleeved inside the support cylinder 32. A vehicle identification monitoring 36 for identifying vehicles is installed on the gantry frame 33. By setting up the vehicle identification mechanism 3 and the barrier gate control system, unauthorized vehicles are effectively prevented from entering, and site security is enhanced.

[0039] The left end of the base 1 is equipped with a barrier system 37 to prevent unauthorized vehicles from entering, and the rear left side of the base 1 is equipped with a road barrier 11 to prevent vehicles from accidentally entering before the weighbridge is extended.

[0040] The mounting plate 31 is also equipped with a lifting cylinder 34. The telescopic end of the lifting cylinder 34 is fixedly connected to the gantry frame 33. An electric telescopic rod 35 is provided on the outside of the support cylinder 32. The telescopic end of the electric telescopic rod 35 slides through the inside of the support cylinder 32 and the left end slides into the inside of the gantry frame 33. By setting the telescopic end of the electric telescopic rod 35, the gantry frame 33 is limited, reducing the risk of the gantry frame 33 falling accidentally.

[0041] Please see Figures 1 to 5 As the first embodiment of this utility model: when maintenance of a single weighing module is required, the weighing platform 21 and the weighing platform 22 can be separated by removing the screws 24 between them. Then, the weighing platform 21 and the weighing platform 22 can be separated by removing the bolts connecting the left end of the weighing platform 21 and the right end of the weighing platform 22. This facilitates the replacement of a single weighing module, allowing for flexible adjustment of the load-bearing capacity. Simultaneously, when the overall scale needs to be expanded or upgraded... During the upgrade process, firstly, insert the splicing blocks 283 of expansion platform 1 281 and expansion platform 2 282 into the splicing slots 26 of weighing platform 1 21 and weighing platform 2 22. Then, connect the rear sides of expansion platform 1 281 and expansion platform 2 282 with screws 24 to achieve fixation. Finally, fix the left end of expansion platform 1 281 and the right end of expansion platform 2 282 to the base 1 by using bolts and internal threads. This achieves the expansion of the scale system size, avoids replacing the entire scale, and reduces upgrade costs.

[0042] Please see Figure 1 , Figure 6As a second embodiment of this utility model: Based on the description in the above embodiments, further, during the use of the weighbridge, when a vehicle enters the field of view of the vehicle identification monitoring 36, the vehicle identification monitoring 36 automatically captures the vehicle image and transmits it to the external processor. The external processor compares the identified license plate number with the authorized license plates in the database. When the license plate number is in the database and the status is valid, the external processor sends a lifting command to the barrier gate system 37, thereby allowing the vehicle to pass through. This reduces the reliance on operators. Moreover, after the load-bearing capacity of the weighbridge is improved by replacing the module, the electric telescopic rod 35 can be activated and its telescopic end can be displaced. When the telescopic end of the electric telescopic rod 35 is displaced out of the gantry 33, the lifting cylinder 34 can be activated. The telescopic end of the lifting cylinder 34 then drives the gantry 33 to lift, ensuring that the upgraded load-bearing capacity of the weighbridge can accommodate vehicles of different heights.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
