[0030] 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.

[0031] like Figures 1 to 8 As shown, this utility model provides a weighbridge for trucks, comprising:

[0032] Weighbridge body 1, with a base plate 2 fixedly installed at the bottom end of weighbridge body 1, and a weighing sensor installed on weighbridge body 1;

[0033] The adjustment mechanism is located on the left side of the top of the base plate 2;

[0034] The adjustment mechanism includes a column 3, a rotating block 4 is movably sleeved inside the column 3, a round shaft 5 is fixedly installed at the bottom of the rotating block 4, a driven gear 6 is fixedly sleeved on the outer surface of the round shaft 5, the top of the driven gear 6 is fixedly connected to the bottom of the rotating block 4, a lead screw 7 is fixedly installed at the top of the rotating block 4, a lifting rod 8 is threadedly sleeved on the outer surface of the lead screw 7, the outer surface of the lifting rod 8 is movably sleeved inside the column 3, a connecting block 9 is fixedly installed at the top of the lifting rod 8, and a display 10 is fixedly installed on the left side of the connecting block 9.

[0035] Because the outer surface of the rotating block 4 is movably connected to the inside of the column 3, the driven gear 6 can drive the rotating block 4 to rotate inside the column 3 via the round shaft 5. At this time, the rotating block 4 will drive the lead screw 7 to rotate. Because the outer surface of the lead screw 7 is connected to the internal thread of the lifting rod 8, the lead screw 7 will drive the lifting rod 8 to move up and down along the inside of the column 3. At this time, the lifting rod 8 will drive the display 10 to move up and down through the connecting block 9, so that the height of the display 10 can be adjusted according to the usage requirements.

[0036] Among them, a fixing plate 11 is fixedly sleeved on the outer surface of the column 3, a drive motor 12 is fixedly installed on the top of the fixing plate 11, a rotating shaft 13 is fixedly sleeved on the other end of the output shaft of the drive motor 12, a drive gear 14 is fixedly sleeved on the bottom of the outer surface of the rotating shaft 13, and the outer surface of the drive gear 14 meshes with the outer surface of the driven gear 6.

[0037] When the drive motor 12 is running, the rotating shaft 13 will drive the drive gear 14 to rotate. Since the drive gear 14 is meshed with the driven gear 6, the drive gear 14 will drive the driven gear 6 to rotate.

[0038] Among them, a vertical block 15 is fixedly installed on the outer surface of the lifting rod 8, and the outer surface of the vertical block 15 is movably connected to the inside of the column 3.

[0039] Due to the design of the column 3 and the vertical block 15, the column 3 can limit the movement of the lifting rod 8 through the vertical block 15, so that it can only move up and down.

[0040] Among them, guardrails 16 are fixedly installed on both the left and right sides of the top of the base plate 2. The guardrails 16 are made of metal.

[0041] Due to the design of guardrail 16, it can provide good protection for vehicles located at the top of the weighbridge body 1.

[0042] The weighbridge body 1 has inclined plates 17 fixedly installed on both the front and rear sides, and reinforcing blocks 18 are provided inside the inclined plates 17.

[0043] The design of the ramp 17 reduces the resistance of vehicles moving to the top of the weighbridge body 1, thus facilitating vehicle weighing. The design of the reinforcing block 18 enhances the structural strength of the ramp 17.

[0044] The inclined plate 17 has a fixed shell 19 inside, a fixed shaft 20 inside the fixed shell 19, a circular block 21 on the outer surface of the fixed shaft 20, a camera 22 on the outer surface of the circular block 21, and several sets of LED beads 23 on the camera 22.

[0045] Due to the design of the camera 22, it can capture and record the vehicle's license plate. Due to the design of the LED bead 23, it can provide good lighting. Due to the movable connection between the round block 21 and the fixed shaft 20, the round block 21 can drive the camera 22 to rotate around the fixed shaft 20 as the axis, thereby capturing the license plate in different positions.

[0046] Among them, a spiral block 24 is provided on the outer surface of the circular block 21, and a moving block 25 is movably connected to the outer surface of the spiral block 24. The outer surface of the moving block 25 is in contact with the outer surface of the circular block 21.

[0047] When the moving block 25 moves left and right along the outer surface of the circular block 21, it will squeeze the outer surface of the spiral block 24, thereby causing the circular block 21 to rotate around the fixed shaft 20.

[0048] The moving block 25 has a screw 26 threaded inside, and both ends of the screw 26 are movably connected to the inside of the fixed shell 19. The driven wheel 27 is fixedly connected to the left end of the screw 26.

[0049] Since the screw 26 is threadedly connected to the moving block 25, when the driven wheel 27 drives the screw 26 to rotate, the screw 26 will drive the moving block 25 to move left and right along the outer surface of the round block 21.

[0050] The left end of the fixed housing 19 is fixedly installed with a motor protective housing 28, and the motor protective housing 28 is fixedly installed with a power motor 29. The other end of the output shaft of the power motor 29 is fixedly sleeved with a rotating shaft 30, and the other end of the rotating shaft 30 is fixedly sleeved with a drive wheel 31. The drive wheel 31 is connected to the driven wheel 27 through a transmission belt 32.

[0051] When the power motor 29 is running, the rotating shaft 30 will drive the drive wheel 31 to rotate, and the drive wheel 31 will drive the two driven wheels 27 to rotate through the transmission belt 32.

[0052] Among them, a fixed post 33 is movably connected to the outer surface of the transmission belt 32, and the right end of the fixed post 33 is fixedly connected to the left end of the fixed shell 19.

[0053] Due to the design of the fixed column 33, the contact area between the transmission belt 32 and the drive wheel 31 and the driven wheel 27 can be increased, thereby ensuring the stability of the transmission of the transmission belt 32.

[0054] Working principle and usage process of this utility model:

[0055] When a vehicle needs to be weighed, the driver first guides the vehicle along the ramp 17 to the top of the weighbridge body 1. Due to the design of the ramp 17, the resistance encountered by the vehicle reaching the top of the weighbridge body 1 is reduced. During this process, the camera 22 captures and records the vehicle's license plate and displays it simultaneously on the monitor 10. When the shooting environment is dark, the design of the LED beads 23 provides good illumination. Because different vehicle models have different license plate positions, when the operator needs to capture license plates in different positions, the operator starts the power motor 29. The rotating shaft 30 then drives the drive wheel 31 to rotate. The drive wheel 31 then drives the two driven wheels 27 to rotate via the transmission belt 32. Due to the four fixed columns 33... The design increases the contact area between the transmission belt 32 and the driven wheel 27, thereby ensuring the stability of the transmission belt 32. At the same time, the two driven wheels 27 will drive the two screws 26 to rotate. Since the outer surfaces of the two screws 26 are threaded into the inner threads of the moving block 25, when the two screws 26 rotate, they will drive the moving block 25 to move to the left. Since the interior of the moving block 25 is movably connected to the outer surface of the spiral block 24, when the moving block 25 moves to the left, it will squeeze and push the outer surface of the spiral block 24. At this time, the spiral block 24 will drive the circular block 21 to rotate along the outer surface of the fixed shaft 20. At this time, the camera 22 will rotate under the drive of the circular block 21, thereby realizing the function of clearly capturing license plates in different positions.

[0056] When the vehicle is at the top of the weighbridge body 1, the elastic body of the weighing sensor on the weighbridge body 1 will undergo elastic deformation under the action of the weight of the goods. This causes the strain gauge bridge circuit impedance attached to the elastic body to lose balance and output an electrical signal proportional to the weight value. Then, the sensor's internal electronic components process and output a digital signal, which is then transmitted to the computer via a repeater and displayed on the monitor 10. This allows the operator to intuitively understand the vehicle's weight information.

[0057] When the operator needs to adjust the height of the display 10, the operator starts the drive motor 12. The rotating shaft 13 then drives the drive gear 14 to rotate. Since the outer surface of the drive gear 14 meshes with the outer surface of the driven gear 6, the driven gear 6 rotates under the drive of the drive gear 14. Immediately afterwards, the rotating block 4 rotates inside the column 3 under the drive of the driven gear 6. At the same time, the lead screw 7 rotates under the drive of the rotating block 4. Since the outer surface of the lead screw 7 is threaded into the lifting rod 8, when the lead screw 7 rotates, it drives... When the lifting rod 8 moves, the vertical block 15 will move under the action of the lifting rod 8. Since the outer surface of the vertical block 15 is slidably connected to the inside of the column 3, the movement of the vertical block 15 will be limited by the inside of the column 3, so that the vertical block 15 can only move up and down. At this time, the vertical block 15 will move upward along the inside of the column 3 under the action of the lifting rod 8. At the same time, the lifting rod 8 will drive the connecting block 9 to move upward. At this time, the display 10 will move upward under the action of the connecting block 9, thereby realizing the function of adjusting the height of the display 10 according to the usage requirements.
