Description

Technical Field

[0001] This utility model relates to the field of metrological weighing vehicle technology, specifically a metrological weighing vehicle testing device. Background Technology

[0002] The weighing and inspection vehicle is mainly used for the inspection of all large scales in various industries across the country, such as highway toll stations, metal wholesale markets, metal warehouses, metallurgy, mines, manufacturing enterprises, grain warehouses, grain purchasing and wholesale, railways, etc. Wherever there are scales, they need to be inspected.

[0003] The current mainstream testing method is to place standard gauges, such as one-ton or two-ton weights, onto the scale for comparison testing. In the past, the traditional method was to use a flatbed truck with a truck-mounted crane to lift the weights onto the scale for testing. However, the disadvantages are that the truck-mounted crane is expensive to manufacture and maintain, the testing range is limited by the arm length, and it occupies a large area.

[0004] Later, a box-type weighing and inspection vehicle using forklifts was developed. Forklifts are inexpensive to operate, easy to maintain, and not limited by transport distance, making them the current main model. However, their disadvantages are that they are generally heavy, usually more than 4 tons, which limits the amount of weights that can be carried. Forklifts are also relatively tall, generally 2.3 meters, and with the extra space, the internal height of the box is 2.5 meters, resulting in a tall vehicle body that affects maneuverability.

[0005] The two types of weighing and inspection vehicles mentioned above are too large, and may be difficult to operate in mountainous areas or other locations with high space requirements. Therefore, a weighing and inspection vehicle testing device is proposed to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a weighing and inspection vehicle testing device, which has the advantage of compact structure and solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a weighing and inspection vehicle testing device, comprising a vehicle body, a cargo box fixed to the top of the shelf of the vehicle body, two clearance slots opened on the right side of the vehicle body, each clearance slot being provided with a hinge assembly for easy lifting, a loading assembly for easy loading and unloading of materials on the inner top wall of the cargo box, a stabilizing assembly for increasing the weight of the vehicle body on the inner bottom wall of the cargo box, and a lifting assembly between the two hinge assemblies;

[0008] Each of the hinged assemblies includes a liquid tank, two support plates, two liquid pumps, and two hydraulic cylinders. The inner wall of the clearance groove is fixed to the liquid tank. The inner side of the clearance groove, located on the right side of the liquid tank, is fixed to the two support plates. The top of each support plate is fixed to the liquid pumps. The inner side of each clearance groove is hinged to the two hydraulic cylinders.

[0009] By adopting this technical solution, the articulated assembly can help the lifting assembly adjust its posture smoothly, so that the lifting assembly can come into contact with the cargo box when the vehicle is in motion.

[0010] Furthermore, each of the liquid pumps has a liquid inlet pipe fixedly connected to its left side, and each liquid inlet pipe extends into the liquid tank. Each of the liquid pumps has a bellows fixedly connected to its right side, and the two bellows, on the side away from the liquid pump, are respectively fixedly connected to two hydraulic cylinders.

[0011] By adopting this technical solution, the hydraulic pump can provide power for the flow of hydraulic oil, ensuring that the hydraulic oil flows smoothly into the hydraulic cylinder.

[0012] Furthermore, the loading assembly includes a track, a trolley, and a chain electric hoist. The top of the cargo box is fixed to the track, the trolley is mounted on the track, and the bottom of the trolley is fixed to the chain electric hoist.

[0013] By adopting this technical solution, and through the cooperation of a crane and a chain electric hoist, the loading and unloading of weights can be guaranteed to proceed smoothly.

[0014] Furthermore, the right side of the cargo box is open, and a movable door is hinged to the right side of the cargo box.

[0015] By adopting this technical solution, the movable door can work in conjunction with the cargo box, thereby helping to maintain stability inside the cargo box.

[0016] Furthermore, the stabilizing component includes a weighing scale, multiple support platforms, and multiple weights. The bottom wall of the cargo box is fixed to the weighing scale, the top of the weighing scale is fixed to the multiple support platforms, the top of the weighing scale has a fixing groove, the fixing groove is provided with multiple weights, and each weight has an extension rod fixed on both its front and rear sides. The multiple extension rods respectively abut against the multiple support platforms.

[0017] By adopting this technical solution, the scale is used to weigh weights. By comparing the weight difference before and after the weight is placed on and after it is removed, the actual weight of the weight can be obtained.

[0018] Furthermore, the lifting assembly includes a loading plate, two ribs, four extension blocks, and two secondary hinge rods. The right side of the loading plate is fixed to the two ribs, the bottom of the loading plate is fixed to the four extension blocks, and the opposite side of every two extension blocks is fixed to the secondary hinge rod.

[0019] By adopting this technical solution, the lifting component is used to help the weights move up and down smoothly.

[0020] Furthermore, two hinge slots are provided on the right side of the loading plate, and a primary hinge rod is fixed inside each hinge slot.

[0021] By adopting this technical solution, the primary articulated rod plays a connecting role, helping to connect the loading plate to the hydraulic cylinder.

[0022] Furthermore, the lifting assembly is hinged to four hydraulic cylinders via two primary hinge rods and two secondary hinge rods, and a stabilizing groove is provided on the left side of the loading plate.

[0023] By adopting this technical solution, the secondary hinge rod also serves a connecting function.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] 1. The weighing and inspection vehicle testing device, through the cooperation of the loading component and the articulation component, can smoothly realize the loading and unloading of weights, while having a more compact structure, and can be more convenient to operate in mountainous terrain and other places with limited space.

[0026] 2. The weighing and balancing vehicle testing device is more convenient to use on the road due to its smaller overall size. At the same time, the stabilizing components can provide good stability for multiple weights. Furthermore, by testing the weights with a scale, the actual weight of each weight can be more clearly understood, thereby improving the accuracy of the weighing and balancing vehicle.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0033] Please see Figure 1 In this embodiment, a weighing and inspection vehicle testing device includes a vehicle body 1, a cargo box 2 fixed on the top of the shelf of the vehicle body 1, two clearance slots 6 on the right side of the vehicle body 1, each clearance slot 6 is provided with a hinge assembly 3 for easy lifting, the inner top wall of the cargo box 2 is provided with a loading assembly 4 for easy loading and unloading, the inner bottom wall of the cargo box 2 is provided with a stabilizing assembly 5 to increase the weight of the vehicle body 1, and a lifting assembly 7 is provided between the two hinge assemblies 3.

[0034] In addition, each hinge assembly 3 includes a hydraulic tank 301, two support plates 302, two hydraulic pumps 303, and two hydraulic cylinders 304. The hydraulic tank 301 is filled with hydraulic oil, and the hydraulic pumps 303 provide power for the flow of hydraulic oil. The inner wall of the clearance groove 6 is fixed to the hydraulic tank 301. The inner side of the clearance groove 6, located on the right side of the hydraulic tank 301, is fixed to the two support plates 302. The clearance groove 6 provides a certain space for the hinge assembly 3, reducing the possibility of the hinge assembly 3 hitting the bottom during vehicle operation due to its low height. The top of each support plate 302 is fixed to the hydraulic pump 303. The inner side of each clearance groove 6 is hinged to the two hydraulic cylinders 304. The side of the hydraulic tank 301 away from the vehicle body 1 is connected to a filler cap by threads.

[0035] It should be further explained that each hydraulic pump 303 has a fixed inlet pipe on its left side. The bellows and the inlet pipe provide power for the flow of hydraulic oil. Each inlet pipe extends into the hydraulic tank 301. Each hydraulic pump 303 has a fixed bellows on its right side. The bellows can better adapt to the angle changes of the hydraulic cylinder 304 during operation. The two bellows are fixedly connected to the two hydraulic cylinders 304 on the side away from the hydraulic pump 303, respectively.

[0036] In addition, the loading component 4 includes a track 401, a trolley 402, and a chain electric hoist 403. The chain electric hoist 403 saves space significantly with its lightweight die-cast aluminum body and compact design, and its energy consumption is lower than that of traditional hoists. The top of the cargo box 2 is fixed to the track 401, and the trolley 402 is installed on the track 401. The trolley 402 works in conjunction with the track 401 to help the loading component 4 move smoothly. The bottom of the trolley 402 is fixed to the chain electric hoist 403. The right side of the cargo box 2 is open, and a movable door is hinged to the right side of the cargo box 2. The movable door can improve the stability of the interior of the cargo box 2, and can be quickly opened when the weight 503 needs to be unloaded, making it convenient to load and unload goods.

[0037] In this embodiment, a control device is installed inside the vehicle body 1. The control device controls the operation of four hydraulic pumps 303, thereby controlling the four hydraulic cylinders 304 and thus smoothly adjusting the posture of the lifting assembly 7.

[0038] Please see Figures 1 to 4 To facilitate loading and unloading, the stabilizing component 5 in this embodiment includes a weighing scale 501, multiple support platforms 502, and multiple weights 503. The bottom wall of the cargo box 2 is fixed to the weighing scale 501, and the top of the weighing scale 501 is fixed to the multiple support platforms 502. The top of the weighing scale 501 has a fixing groove, which provides the necessary space for the weights 503 to ensure that the extension rod can be smoothly placed into the support platform 502. The top of the support platform 502 is arc-shaped, which can better fit the extension rod. Multiple weights 503 are set in the fixing groove, and extension rods are fixed on both the front and rear sides of each weight 503. The multiple extension rods abut against the multiple support platforms 502 respectively.

[0039] Furthermore, the lifting assembly 7 includes a loading plate 701, two ribs 702, four extension blocks 704, and two secondary hinge rods 705. The right side of the loading plate 701 is fixed to the two ribs 702, which can improve the overall strength of the loading plate 701. The bottom of the loading plate 701 is fixed to the four extension blocks 704. The opposite side of every two extension blocks 704 is fixed to the secondary hinge rods 705. The secondary hinge rods 705 and the primary hinge rods 703 cooperate to connect the loading plate 701 and the hydraulic cylinder 304, thereby smoothly adjusting the posture of the loading plate 701.

[0040] It is known that two hinge slots are provided on the right side of the loading plate 701, and a primary hinge rod 703 is fixed inside each hinge slot. The lifting assembly 7 is hinged to four hydraulic cylinders 304 through the two primary hinge rods 703 and the secondary hinge rods 705 respectively. A stabilizing slot 706 is provided on the left side of the loading plate 701. The stabilizing slot 706 can provide lateral support for the weight 503. Since multiple hydraulic cylinders 304 work together, it is difficult to ensure that the loading plate 701 is always in a horizontal state when adjusting the height of the loading plate 701. At this time, the stabilizing slot 706 can provide a certain lateral support and improve the safety of operation.

[0041] In this embodiment, by comparing the weight difference of the weight 503 before and after it is placed and after it is removed by the stabilizing component 5, the actual weight of the weight 503 can be obtained, thereby improving the accuracy of the weighing and verification vehicle when in use.

[0042] Understandably, when the vehicle body 1 is in normal driving, the loading plate 701 will abut against the movable door, thereby improving the stability of the cargo box 2. Compared with mainstream weighing and inspection vehicles, this device occupies less space and is more convenient to use in locations with high space requirements. This device does not require a truck-mounted crane or a forklift, so the truck body is much lower and lighter. The loading and unloading of the weight 503 can be completed with a very small loading plate 701 at the rear of the vehicle, achieving green and low-carbon development.

[0043] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0044] The working principle of the above embodiments is as follows:

[0045] When it is necessary to unload weight 503, the user first needs to enter the cargo box 2, fix the weight 503 to be unloaded onto the hanging device, etc., and then start the crane 402 to move to the designated position. At the same time, start the electric chain hoist 403. After the hook of the electric chain hoist 403 is attached to the hanging device, the weight 503 is moved upward under the traction of the electric chain hoist 403 and moves towards the lifting component 7. By controlling the two hinge components 3, multiple hydraulic cylinders 304 are controlled to extend and retract to different degrees, so that the loading plate 701 is in a horizontal state. After the loading component 4 places the weight 503 on the loading plate 701, the hinge components 3 are controlled to make the loading plate 701 descend until the upper end of the loading plate 701 touches the ground. The user can then easily unload the weight 503. When it is necessary to add weight 503, the same principle applies; simply reverse the operation.
