AI Technical Summary
When using a vehicle weighing weigher, some vehicles may continue to rush forward without braking in time due to large weight and inertia, resulting in a shift in the center of gravity, affecting the accuracy of the weighing data, and may even cause vehicles and cargo to fall off the weighing weigher.
A vehicle weighing weighing device with a guide slope is designed, and an infrared detection lamp is installed on the inside of the weighing weighing device body by fixing an upper guide slope with a triangular cross-section on one side of the weighing weighing device body. When the infrared detection light detects the vehicle's obstruction, the stepper motor is controlled to start, driving the connecting shaft and the connecting plate to rotate, forming a structure that prevents the vehicle from continuing to move forward, and at the same time, anti-slip strips are installed at the up and downhill to prevent slope slipping.
It effectively prevents the vehicle from rushing forward under the influence of inertia, maintains the stability of the vehicle and cargo, ensures the accuracy of weighing data, and reduces the occurrence of slope slips through anti-slip strips.

Description
Technical Field
[0001] The utility model relates to the technical field of vehicle weighing scales, in particular to a vehicle weighing scale with a guide slope. Background Art
[0002] Electronic vehicle scales, also known as electronic floor scales or floor scales, are the main weighing equipment used by factories, mines, and businesses for measuring bulk goods. Before the 1980s, common electronic floor scales were generally mechanical electronic floor scales with purely mechanical structures based on the principle of levers, also known as mechanical floor scales. In the mid-1980s, with the increasing maturity of high-precision weighing sensor technology, mechanical floor scales were gradually replaced by electronic floor scales with high precision, good stability, and easy operation. Vehicle weighing scales are usually equipped with ramps when in use to facilitate vehicles to drive onto the weighing scale's table and to the ground after weighing.
[0003] For some vehicles, because the vehicle and the cargo on the vehicle are heavy, and the driver fails to brake in time after driving the vehicle on the weighing scale, the vehicle may continue to rush forward under the influence of inertia. If the vehicle is not adjusted, the center of gravity of the vehicle and the cargo may be biased, affecting the weighing data of the weighing scale, and even causing the vehicle to fall off the weighing scale. Therefore, a vehicle weighing scale with a guide slope is proposed to address the above problems. Utility Model Content
[0004] The utility model aims to provide a vehicle weighing scale with a guide slope to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0026] See also Figure 1-5 , the utility model provides a technical solution:
[0027] A vehicle weighing scale with a guide slope comprises a weighing scale body 1, a mounting seat 14 and a stepping motor 8, wherein an upper guide slope 2 having a triangular cross section is fixedly connected to one side of the weighing scale body 1, an infrared detection lamp 3 is installed on the inner side of the upper guide slope 2, mounting blocks 5 protruding from the weighing scale body 1 are fixedly connected to both sides of the weighing scale body 1, a bearing 6 whose inner ring and outer ring rotate relative to each other is fixedly connected to the inner side of the mounting block 5, a connecting shaft 7 is fixedly connected to the inner side of the inner ring of the bearing 6, a controller 15 electrically connected to both the infrared detection lamp 3 and the stepping motor 8 is installed at the bottom of the stepping motor 8, a rod sleeve 9 is sleeved on the outer side of the connecting shaft 7, a connecting plate 10 is fixedly connected to the outer side of the rod sleeve 9, an elastic protective plate 11 is fixedly connected to the upper end surface of the connecting plate 10, and a lower guide slope 13 is rotatably connected to the other side of the connecting plate 10.
[0028] The upper end surface of the upper guide slope 2 is fixedly connected with a plurality of first anti-skid strips 4 of equal size, which are evenly arranged. This arrangement can prevent the vehicle from slipping when going uphill to a certain extent, reducing the situation where the vehicle slides downhill; the upper end surface of the elastic protective plate 11 is fixedly connected with a plurality of second anti-skid strips 12 of equal size, which are evenly arranged. The elastic protective plate 11 is arranged on the side of the weighing scale body 1 away from the upper guide slope 2. This arrangement can prevent the vehicle from slipping when going downhill to a certain extent, reducing the situation where the vehicle slides downhill; the connecting plate 1 0 is provided with an arc-shaped groove on one side close to the rod sleeve 9, and an arc-shaped protrusion on one side of the connecting plate 10 close to the lower guide slope 13, and an arc-shaped groove on one side of the lower guide slope 13 close to the connecting plate 10. This arrangement enables the connecting plate 10 to be stably fixedly connected to the rod sleeve 9, and the connecting plate 10 can be stably rotatably connected to the lower guide slope 13; one end of the connecting shaft 7 is fixedly connected to the end of the output shaft of the stepping motor 8, and the rod sleeve 9 is fixedly connected to the connecting shaft 7. This arrangement enables the stepping motor 8 to drive the connecting shaft 7 to rotate, and the connecting shaft 7 can drive the rod sleeve 9 to rotate.
[0029] Working process: All electrical appliances in the utility model are provided with an external power supply. When the vehicle is to be weighed by a vehicle weighing scale with a guide slope, the vehicle is guided by the upper guide slope 2 and slowly drives to the weighing scale body 1 installed by the mounting seat 14. The first anti-skid strip 4 can prevent the vehicle from slipping uphill to a certain extent, and reduce the situation where the vehicle slips down the slope. When the infrared detection light 3 detects that it is blocked by the vehicle, it will reflect the signal to the controller 15. The controller 15 controls the stepper motor 8 to start, and the rotating shaft of the stepper motor 8 drives the connecting shaft 7 to rotate counterclockwise. The connecting shaft 7 rotates with the inner ring of the bearing 6. The bearing 6 is installed through the mounting block 5. The rotation of the connecting shaft 7 drives the rod sleeve 9 and the connecting plate 10 to rotate. At this time, the connecting plate 10 is separated from the lower guide slope 13 and rotates in an upward trend. When the connecting plate 10 rotates 90° quickly and stops rotating, the connecting plate 10 can block the vehicle at this time, and the vehicle may touch the elastic protective plate. 11 and the second anti-skid strip 12, the elastic protective plate 11 and the second anti-skid strip 12 are both elastic structures, which can protect the vehicle to a certain extent, and in the process of the vehicle passing through the upper guide slope 2 to the weighing scale body 1, the driving speed is usually slow, so there will be no sudden collision with the connecting plate 10, and there will be no danger to the driver's safety. When the infrared detection light 3 detects that it is not blocked, it transmits a signal to the controller 15, and the controller 15 makes the rotating shaft of the stepper motor 8 rotate clockwise, that is, the connecting plate 10 rotates in the direction close to the lower guide slope 13. When the arc-shaped protruding side of the connecting plate 10 is in contact with the arc-shaped grooved side of the lower guide slope 13, the stepper motor 8 stops running, and then the car can leave the weighing scale body 1 through the guidance of the connecting plate 10 and the lower guide slope 13. The second anti-skid strip 12 can prevent the vehicle from slipping downhill to a certain extent, reducing the occurrence of the vehicle sliding downhill.
