Description

Technical Field

[0001] This invention relates to the field of vehicle dynamic weighing technology, and in particular to a vehicle dynamic weighing device. Background Technology

[0002] Currently, while vehicles are being dynamically weighed, manual data collection is still required, which increases the workload of staff and makes it difficult to compare real-time vehicle data with vehicle type data in the database, thus reducing the efficiency of vehicle type identification.

[0003] In addition, when dealing with illegal and irregular behaviors such as overweight and oversized transport vehicles on highways, off-site enforcement systems are often used as the basis for off-site enforcement. It is necessary to scientifically obtain accurate information such as the number of axles, axial direction, speed and axle load of the transport vehicles.

[0004] To obtain accurate information such as the number of axles, axial direction, speed, and axle load of transport vehicles, existing technologies generally employ a narrow-strip weighing device for dynamic vehicle weighing. This device includes a load-bearing beam structure, beneath which are multiple sets of load cells arranged in a straight line. Below the load cells are ground anchor plates, and above the beam structure is a grindable layer of a certain thickness. Flexible partition layers surround the grindable layer, the beam structure, and the load cells. The ground anchor plates are used to connect and fix the narrow-strip weighing device to the roadbed, the grindable layer is used for leveling with the roadbed and bearing load, and the flexible partition layers separate the grindable layer, the beam structure, the load cells, and the roadbed. Each load cell generates two weighing signals to determine the vehicle's direction of travel and obtain its speed.

[0005] This narrow-strip weighing device enables multi-channel signal output from the weighing sensor, acquiring axial and vehicle speed information on top of traditional narrow-strip weighing functions, thus improving weighing accuracy and reducing costs. However, the process of fixing the ground anchor plate is cumbersome, hindering rapid installation and reducing installation efficiency. Furthermore, the top layer, composed of a grindable layer of concrete, grout, and adhesive, makes it difficult to inspect and replace internal parts, further complicating the device's usability and reducing its practicality.

[0026] (III) Beneficial Effects

[0027] As can be seen from the above technical solution, the vehicle dynamic weighing device provided by the present invention has the following beneficial effects:

[0028] 1. The vehicle dynamic weighing device provided by this invention employs a fixing mechanism consisting of a locking unit, a rotating unit, and a fixing unit connected in sequence. When this fixing mechanism is in operation, rotating the rotating column causes the threaded column to rotate, which in turn causes the fixing column to move upward. When the fixing column moves to the fixing hole inside the ground anchor plate, the fixing column is fixed to the ground anchor plate, that is, the ground anchor plate is fixed to the device. This fixing structure facilitates the rapid fixing of the ground anchor plate, improves the installation efficiency of the device, makes operation more convenient, and solves the problem of low installation efficiency of the device.

[0029] 2. The vehicle dynamic weighing device provided by this invention employs an opening mechanism composed of a moving unit and a pushing unit connected in sequence. When the opening mechanism is in operation, rotating the rotating rod causes the threaded rod to rotate, which in turn causes the pushing block to move upward. The moving pushing block pushes the pressure plate upward to rotate and open. The pressure plate can then be opened by hand. This opening structure facilitates the quick opening of the pressure plate, thereby facilitating the rapid installation or replacement of internal parts and solving the problem of the inability to inspect and replace internal parts.

[0053] In this embodiment, the rotation unit facilitates the rotation of the rotating column 9, which in turn drives the first gear disk 13 to rotate.

[0055] In this embodiment, this fixing unit facilitates the movement of the fixing column 16 into the interior of the ground anchor plate 17, thereby facilitating the rapid fixing of the ground anchor plate 17 and the T-shaped plate 3.

[0056] According to an embodiment of the present invention, the opening mechanism includes a moving unit and a pushing unit connected sequentially as one unit.

[0057] In a further preferred embodiment of the present invention, such as Figure 4-5 As shown, the moving unit in the opening mechanism includes: a rotating rod 6 disposed on one side of the fixed plate 5 and extending into the interior of the fixed plate 5; a threaded rod 18 disposed on one side of the rotating rod 6; an L-shaped moving block 19 sleeved on the outer wall of the threaded rod 18; a connecting post 20 disposed at the top end of one end of the L-shaped moving block 19 and rotatably sleeved with the pressure plate 4; and a second gear 23 fixedly sleeved on the middle end of the outer wall of the threaded rod 18.

[0058] In this embodiment, the movement unit facilitates the rotation of the rotating rod 6, which in turn drives the threaded rod 18 to rotate, thereby driving the second gear 23 to rotate.

[0060] In this embodiment, the pushing unit facilitates the rotation of the second gear 23, which in turn drives the pushing block 26 to move upward, thereby facilitating the upward pushing and opening of the pressure plate 4.

[0061] In a further preferred embodiment of the present invention, such as Figure 4-5 As shown, the push block 26 has a thread inside that matches the threaded rod 25, and the top of the rotating rod 6 is set as a trapezoidal inclined surface, and the bottom of the pressure plate 4 is set as an arc surface.

[0062] In this embodiment, this structure facilitates the rotation of the threaded rod 25, which drives the push block 26 to move upward. When the push block 26 moves, it helps to squeeze the pressure plate 4 and drive the pressure plate 4 to rotate and open.

[0063] Based on the above Figures 1 to 5 The vehicle dynamic weighing device provided by the present invention is shown below. The working principle of the vehicle dynamic weighing device is described in further detail below:

[0064] Before operation, the vehicle dynamic weighing device first opens the pressure plate 4, then rotates the rotating rod 6. The rotation of the rotating rod 6 drives the threaded rod 18 to rotate, which in turn moves the L-shaped moving block 19 towards the roadbed 1. Simultaneously, the rotation of the threaded rod 18 drives the second gear 23 to rotate, which in turn drives the second gear disc 24 to rotate. The rotation of the second gear disc 24 drives the threaded rod 25 to rotate, which in turn moves the pushing block 26 upward. The moving pushing block 26 pushes the pressure plate 4 upward to rotate and open, thus opening the pressure plate 4. This structure facilitates the rapid opening of the pressure plate 4, thereby enabling quick installation or replacement of internal parts.

[0065] Next, the anchor plate 17 is fixed: the rotating column 8 is inserted into the top of the rotating column 9, the inner wall of the rotating column 9 presses against the sliding block 21, and the spring 22 is compressed. When the sliding block 21 and the groove on the inner wall of the rotating column 9 are at the same horizontal position, the spring 22 resets and drives the sliding block 21 to reset, that is, the rotating column 8 and the rotating column 9 are fixedly engaged. Then the rotating column 8 is rotated, the rotating column 8 rotates and drives the rotating column 9 to rotate, the rotating column 9 rotates and drives the first helical gear 10 to rotate, the first helical gear 10 rotates and drives the second helical gear 11 to rotate, the second helical gear 11 rotates and drives the connecting rod 12 to rotate, the connecting rod 12 rotates and drives the first gear 13 to rotate, the first gear 13 rotates and drives the first gear 14 to rotate, the first gear 14 rotates and drives the threaded column 15 to rotate, the threaded column 15 rotates and drives the fixed column 16 to move upward. When the fixed column 16 moves to the fixing hole inside the anchor plate 17, the fixed column 16 is fixed to the anchor plate 17, that is, the anchor plate 17 is fixed to the device. This structure facilitates the rapid fixing of the ground anchor plate 17, improves the installation efficiency of the device, and makes operation more convenient.
