Description

Technical Field

[0001] This utility model belongs to the field of weighbridge technology and relates to an adjustable weighbridge. Background Technology

[0002] In the field of modern freight transportation and logistics management, the technology for accurately measuring the weight of vehicles and their cargo is crucial. As a widely used weighing device for various types of vehicles, the importance of weighbridges is self-evident. Weighbridges, also known as truck scales, are large weighing devices installed underground. By having vehicles drive onto or place them on a platform, sensor technology is used to accurately measure the total weight of the vehicle. This process is not only crucial for ensuring road safety and preventing overloading, but also serves as an important basis for trade settlement and logistics cost control.

[0003] Traditionally, weighbridge designs have focused on fixed dimensions and load-bearing capacity to accommodate the standard specifications of the main vehicles in circulation at the time. However, with economic development and technological advancements, vehicle types have become increasingly diverse, ranging from light trucks to heavy-duty trailers, with significant differences in width between different vehicle types. This presents challenges for weighbridge applications: on the one hand, to meet the weighing requirements of wider vehicles, the weighbridge platform must be widened accordingly; on the other hand, increasing the width of the weighbridge means requiring more road space for installation, which is particularly difficult in urban areas where land resources are scarce. Therefore, the main challenge currently lies in how to balance the width of the weighbridge to accommodate the needs of different vehicle types while minimizing its footprint. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable weighbridge with an adjustable width design to adapt to the weighing needs of different types of vehicles. During normal use, the width can be shortened to reduce the floor space occupied.

[0005] To solve the above technical problems, this utility model provides an adjustable weighbridge, including a support base frame. Slide rails are provided on both the front and rear sides of the upper end of the support base frame. Two sliding support plates, distributed front and rear, are slidably connected to the upper end of the support base frame. Each sliding support plate has slide bars on its left and right sides that are slidably connected to the corresponding slide rails. Strip-shaped support frames are provided upwards on both the front and rear sides of the support base frame. A strip-shaped connecting frame extending into the support base frame is provided downwards on the inward-facing side of each sliding support plate. A first hydraulic push rod is connected between each strip-shaped connecting frame and its corresponding strip-shaped support frame. The outer edge of each sliding support plate extends outwards from the support base frame, and a downward-facing hydraulic support rod is connected to the lower end of the portion of each sliding support plate extending outwards from the support base frame.

[0006] Each sliding support plate is connected to a weighing plate at its upper end. Multiple weighing sensors are arranged in an array between each weighing plate and its corresponding sliding support plate. Inclined plates are hinged to both sides of each weighing plate. A second hydraulic push rod is rotatably connected between each side of each sliding support plate and its corresponding inclined plate. Multiple strip slots parallel to the slide rail and arranged in a row are opened on the upper side of each weighing plate. The strip slots on the two weighing plates are staggered. A strip insert is provided outward on the inner edge of each weighing plate to cooperate with and slide in the corresponding strip slot.

[0007] By adopting the above technical solution, when width adjustment is required, the hydraulic support rod is first shortened to lift it off the ground, and the second hydraulic push rod is extended to push the ramp plate upwards, lifting it off the ground. At this time, the first hydraulic push rod can be controlled to extend and retract, and the sliding support plate can be slid back and forth by pushing and pulling the strip connecting frame to adjust the distance between the two weighing plates, meeting the weighing needs of different vehicles. During the process, the connection between the strip insert and the strip slot ensures that the two weighing plates are staggered, reducing the risk of the wheel falling off the middle. After the adjustment is completed, the hydraulic support rod extends to support the ground, and the second hydraulic push rod shortens to pull the ramp plate downwards to ground. At this time, the vehicle can be driven from the ramp plate onto the weighing plate, and the weighing is carried out with the help of the weighing sensor.

[0008] The present invention is further configured such that each slide rail has a groove on its outer side that runs along its length, and each slide bar has a T-shaped cross-section that matches the groove.

[0009] The present invention is further configured such that waterproof baffles are provided on both the front and rear sides of each weighing plate, and the lower edge of each waterproof baffle does not extend to the corresponding sliding support plate.

[0010] The present invention is further configured such that a pad is provided on the free edge of each ramp plate, and the pad is horizontal when the pad is at the same height as the lower side of the supporting base.

[0011] The present invention is further configured such that each pad is made of rubber.

[0012] The present invention is further provided with a mesh stiffening rib on the lower side of each weighing plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Firstly, this utility model, through the cooperation of the first hydraulic push rod, the second hydraulic push rod, and the hydraulic support rod, can realize the adjustment of the width of the weighbridge. During normal use, the width is shortened to reduce the footprint, and the width is increased to weigh large vehicles, so as to meet the weighing needs of different types of vehicles.

[0015] Secondly, during the width adjustment process, the two weighing plates are kept staggered by connecting the strip inserts and the strip slots, reducing the risk of the wheel falling out of the middle;

[0016] Thirdly, the load cell uses a waterproof edge to block rainwater from entering from the outside, preventing the load cell from coming into contact with water and being damaged, which helps to extend its service life. Attached Figure Description

The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0024] Example, refer to Figure 1-5An adjustable weighbridge includes a support base 1. A slide rail 2 is provided on both the front and rear sides of the upper end of the support base 1. Each slide rail 2 has a groove 3 extending along its length on its outer side. Two sliding support plates 4 are slidably connected to the upper end of the support base 1, arranged front to back. Each sliding support plate 4 has a sliding strip 5 on its left and right sides that is slidably connected to the corresponding slide rail 2. Each sliding strip 5 has a T-shaped cross-section that matches the groove 3. A strip support frame 6 is provided upwards on both the front and rear sides of the support base 1. A strip connecting frame 7 extending into the support base 1 is provided downwards on the inward-facing side of each sliding support plate 4. Two first hydraulic push rods 8 are connected between each strip connecting frame 7 and the strip support frame 6. When the first hydraulic push rod 8 shortens and pulls the strip connecting frame 7, the sliding support plate 4 can be pushed outwards. Each sliding support plate 4 extends outward from the support base 1. The lower end of the portion of each sliding support plate 4 extending outward from the support base 1 is connected to two downward-facing hydraulic support rods 9. The hydraulic support rods 9 support the ground, increasing the load-bearing capacity of the sliding support plate 4 and also assisting in adjusting the level of the sliding support plate 4.

[0025] Each sliding support plate 4 has a weighing plate 10 connected to its upper end. Each weighing plate 10 has a mesh stiffening rib 11 on its lower side to increase its load-bearing capacity. Four load cells 12 are arranged in an array between each weighing plate 10 and its corresponding sliding support plate 4. Each weighing plate 10 has a waterproof edge 13 on both its front and rear sides, with the lower edge of each waterproof edge 13 not extending to the corresponding sliding support plate 4. This waterproof edge is used to cover the load cells 12 to prevent water damage. Each weighing plate 10 has multiple strip slots 14 arranged parallel to the slide rail 2 on its upper side. The strip slots 14 on two weighing plates 10 are staggered. Each weighing plate 10 has a strip insert 15 extending outwards from its inner edge, which slides and connects with the corresponding strip slot 14. The connection between the strip insert 15 and the strip slot 14 ensures that there is no significant gap between the two weighing plates 10 during movement. Each weighing plate 10 has a ramp plate 16 hinged to both its left and right sides. Each sliding support plate 4 has a second hydraulic push rod 17 rotatably connected to the corresponding ramp plate 16 on both sides. Each ramp plate 16 has a pad 18 made of rubber material on its free side. When the pad 18 is at the same height as the lower side of the support base 1, the pad 18 is horizontal.

[0026] Working principle: When width adjustment is required, the hydraulic support rod 9 is first shortened to lift it off the ground, and the second hydraulic push rod 17 is extended to push the ramp plate 16 upward, lifting it off the ground. At this time, the first hydraulic push rod 8 can be controlled to extend and retract, and the sliding support plate 4 can be slid back and forth by pushing and pulling the strip connecting frame 7 to adjust the distance between the two weighing plates 10 to meet the weighing requirements of different vehicles. During the process, the connection between the strip insert 15 and the strip slot 14 keeps the two weighing plates 10 staggered, reducing the risk of the wheel falling off the middle. After the adjustment is completed, the hydraulic support rod 9 is extended to support the ground, and the second hydraulic push rod 17 is shortened to pull the ramp plate 16 downward to ground. At this time, the vehicle can be driven from the ramp plate 16 onto the weighing plate 10, and the weighing is carried out with the help of the weighing sensor 12.
