Description

Technical Field

[0001] This utility model specifically relates to a motor vehicle axle load tester, belonging to the technical field of motor vehicle axle load testers. Background Technology

[0002] The vehicle axle load meter, also known as a vehicle wheel load meter, vehicle wheel load instrument, or whole wheel axle load weighing system, is mainly used in axle load measurement, overload detection, and other fields, bringing great convenience to road administration, municipal administration, safety inspection and other departments.

[0003] In the use of existing motor vehicle axle load meters, in order to facilitate the inspection of motor vehicles, two sets of inclined triangular plates are usually set up, and anti-slip strips are set on the triangular plates to prevent the motor vehicle from slipping. However, due to the heavy weight of the motor vehicle, the anti-slip effect of a single anti-slip strip is poor. Moreover, when the motor vehicle is going uphill, the raised part of the anti-slip strip will also cause some obstruction to the uphill, and may even cause the vehicle to bump. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a motor vehicle axle load tester. A movable anti-slip component is installed on the triangular plate, which provides an anti-slip effect for the motor vehicle while avoiding obstruction of the vehicle's uphill driving.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a motor vehicle axle load tester, comprising a fixed plate, the fixed plate being arranged in an "n" shape, two bases being fixedly connected to the bottom of the fixed plate, each of the two bases having several mounting holes, and two triangular plates being movably mounted on the top of the two bases, the two triangular plates being respectively attached to the left and right sides of the fixed plate, and the axle load tester body being clamped and mounted between the two triangular plates, the inner cavity of the fixed plate being provided with an adjustment component, and the inclined surfaces of the two triangular plates being provided with anti-slip components.

[0006] Preferably, the adjustment component includes a servo motor located inside the fixed plate cavity, and screws are fixedly connected to both sides of the servo motor. The two screws pass through the side wall of the fixed plate and are threadedly connected to the outer wall of the corresponding triangular plate, and the two screws are movably connected to the outer wall of the fixed plate.

[0007] To adjust the distance between the two triangular plates, it is convenient to clamp and install the main body of the axle load meter, and also to facilitate subsequent disassembly and maintenance.

[0008] Preferably, each of the two triangular plates has a threaded groove on its opposite side, and the two screws are respectively threaded into the inner cavity of the corresponding threaded groove.

[0009] In order to enable the smooth movement of the triangle plate, the threaded connection between the threaded groove and the screw rod allows the triangle plate to move when the screw rod rotates.

[0010] Preferably, the servo motor is fixedly connected to a base on its top, and the base is fixedly connected to the top of the inner wall of the fixing plate.

[0011] To ensure stable operation of the servo motor, it is fixed to the top of the inner wall of the mounting plate to improve stability.

[0012] Preferably, the anti-slip component includes several movable baffles, and several side grooves are formed on the inclined surface of the triangular plate. The several movable baffles are respectively located in the inner cavity of the corresponding side grooves, and a round shaft is fixedly installed through the movable baffle. The two ends of the round shaft pass through the inner wall of the side groove and are movably connected to the inner wall of the side groove. The two ends of the round shaft are fixedly installed with blocks. A torsion spring is fixedly connected between the opposite side of the two blocks and the outer wall of the triangular plate. The torsion spring is sleeved on the outside of the round shaft.

[0013] To improve the anti-slip performance of the triangular plate's inclined surface, multiple sets of movable baffles are installed to block the wheels of motor vehicles and prevent them from slipping backward.

[0014] Preferably, rubber pads are embedded in the opposite sides of the two triangular plates near the top, and the two rubber pads are respectively attached to the outer walls of the axle load cell body.

[0015] To improve the stability of the axle load meter during installation, rubber pads 10 are used to increase friction.

[0016] Preferably, each of the two bases has two sliding grooves, and each of the two triangular plates is fixedly connected to two sliders, which are slidably connected to the inner cavity of the corresponding sliding groove.

[0017] To prevent the triangle from moving out of place, two sets of sliders and grooves are used to limit the movement trajectory of the triangle.

[0018] Preferably, a plurality of cooling fans are fixedly installed between the two bases, and a plurality of ventilation holes are provided on the top of the fixing plate.

[0019] To improve heat dissipation performance, a cooling fan is used to cool the servo motor, and the ventilation holes also provide auxiliary heat dissipation for the main body of the axle load meter.

[0020] The beneficial effects of this utility model are as follows: This motor vehicle axle load tester, by setting up a buffer component, will sequentially press multiple movable baffles when the motor vehicle drives onto the inclined plane of the triangular plate, causing the movable baffles to drive the corresponding round shafts to rotate. The round shafts drive the blocks to compress the corresponding torsion springs. At this time, the movable baffles are embedded in the side grooves and will not obstruct the motor vehicle's uphill movement. When the motor vehicle leaves the movable baffles, the movable baffles will be reset under the elastic force of the two sets of torsion springs. At this time, the movable baffles are set at an angle and are limited by the inner wall of the side grooves, which can play a role in preventing the wheels of the motor vehicle from slipping and avoiding the motor vehicle from slipping backward.

[0021] Equipped with a servo motor, screws, and triangular plates, the servo motor can be driven to rotate the two screws synchronously when the axle load cell needs to be disassembled for maintenance. The two screws then move the corresponding triangular plates away from the axle load cell. The servo motor can then be turned off, and the axle load cell can be removed. Disassembly is convenient, and subsequent installation only requires driving the servo motor again to fix the axle load cell. Attached Figure Description

[0029] 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.

[0030] Please see Figures 1-6 As shown, a motor vehicle axle load tester includes a fixed plate 1, which is arranged in an "n" shape. Two bases 2 are fixedly connected to the bottom of the fixed plate 1. Each base 2 has several mounting holes 3. Two triangular plates 4 are movably mounted on the top of the two bases 2. The two triangular plates 4 are respectively attached to the left and right sides of the fixed plate 1, and the axle load tester body 9 is clamped between the two triangular plates 4. An adjustment component is provided in the inner cavity of the fixed plate 1, and anti-slip components are provided on the inclined surfaces of the two triangular plates 4.

[0031] In this embodiment, the two triangular plates 4 clamp the axle load cell body 9, thus achieving the fixed installation of the axle load cell body 9. During subsequent operation, when the vehicle travels on the triangular plates 4 on both sides, it will be affected by the anti-slip components set on the triangular plates 4, effectively preventing the vehicle from slipping. Furthermore, the distance between the two triangular plates 4 can be adjusted using the adjustment components, making it convenient to disassemble and repair the axle load cell body 9.

[0032] Please see Figure 4 and Figure 5 The adjustment component includes a servo motor 16, which is located in the inner cavity of the fixed plate 1. Screws 18 are fixedly connected to both sides of the servo motor 16. The two screws 18 pass through the side wall of the fixed plate 1 and are threaded to the outer wall of the corresponding triangular plate 4. The two screws 18 are movably connected to the outer wall of the fixed plate 1.

[0033] In this embodiment, by driving the servo motor 16, the servo motor 16 drives the two screws 18 to rotate synchronously. The two screws 18 drive the corresponding triangular plates 4 to move. At this time, the two triangular plates 4 move away from the axle load cell body 9. Then the servo motor 16 can be turned off and the axle load cell body 9 can be removed. Disassembly is convenient. During subsequent installation, it is only necessary to drive the servo motor 16 again to complete the clamping and fixing of the axle load cell body 9.

[0034] Please see Figure 5 The two triangular plates 4 each have a threaded groove 19 on one side of their opposite sides, and the two screws 18 are threaded into the corresponding threaded groove 19.

[0035] In this embodiment, the screw 18 and the threaded groove 19 are connected by a thread, so that when the screw 18 rotates, it can smoothly drive the triangular plate 4 to move horizontally and complete the clamping of the axle load cell body 9.

[0036] Please see Figure 4 The servo motor 16 is fixedly connected to the base 17 at the top, and the base 17 is fixedly connected to the top of the inner wall of the fixing plate 1.

[0037] In this embodiment, the servo motor 16 is fixed to the fixed plate 1 by setting the base 17, so as to ensure the stable performance of the servo motor 16 during subsequent operation.

[0038] Please see Figure 6 The anti-slip component includes several movable baffles 12. Several side grooves 11 are provided on the inclined surface of the triangular plate 4. Several movable baffles 12 are respectively located in the inner cavity of the corresponding side grooves 11. A round shaft 13 is fixedly installed through the movable baffles 12. The two ends of the round shaft 13 pass through the inner wall of the side groove 11 and are movably connected to the inner wall of the side groove 11. The two ends of the round shaft 13 are fixedly installed with blocks 14. A torsion spring 15 is fixedly connected between the opposite side of the two blocks 14 and the outer wall of the triangular plate 4. The torsion spring 15 is sleeved on the outside of the round shaft 13.

[0039] In this embodiment, when the vehicle drives onto the inclined surface of the triangular plate 4, it will press down on multiple movable baffles 12 in sequence, causing the movable baffles 12 to drive the corresponding round shafts 13 to rotate. The round shafts 13 drive the stop blocks 14 to compress the corresponding torsion springs 15. At this time, the movable baffles 12 are embedded in the side grooves 11 and will not obstruct the vehicle's uphill movement. When the vehicle drives away from the movable baffles 12, the movable baffles 12 will be reset under the elastic force of the two sets of torsion springs 15. At this time, the movable baffles 12 are inclined and limited by the inner wall of the side grooves 11, which can prevent the wheels of the vehicle from slipping and avoid the vehicle from slipping backward.

[0040] Please see Figure 2 Two triangular plates 4 are each fitted with rubber pads 10 near the top on opposite sides, and the two rubber pads 10 are respectively attached to the outer walls of the axle load cell body 9.

[0041] In this embodiment, by setting the rubber pad 10, on the one hand, the friction between the outer wall of the triangular plate 4 and the outer wall of the axle load cell 9 is increased, and on the other hand, the strong clamping force is prevented from acting directly on the outer wall of the axle load cell 9, thus avoiding damage to the axle load cell 9.

[0042] Please see Figure 3 and Figure 4 Two grooves 6 are provided on each of the two bases 2, and two sliders 5 are fixedly connected to each of the two triangular plates 4. The sliders 5 are slidably connected to the inner cavity of the corresponding groove 6.

[0043] In this embodiment, the slider 5 and the groove 6 work together to allow the slider 5 to slide inside the groove 6 when the triangle plate 4 moves, thereby limiting the horizontal movement trajectory of the triangle plate 4.

[0044] Please see Figure 4 Several cooling fans 7 are fixedly installed between the two bases 2, and several ventilation holes 8 are opened on the top of the fixing plate 1.

[0045] In this embodiment, the servo motor 16 is cooled by the cooling fan 7, and the ventilation holes 8 can also be used to help cool the main body 9 of the axle load meter.
