Description

Technical Field

[0001] This utility model relates to the field of road surface testing equipment technology, and in particular to a convenient continuous eight-wheel road surface evenness tester. Background Technology

[0002] The continuous eight-wheel road surface smoothness tester is mainly used for construction inspection, final acceptance, and road maintenance of highways, urban roads, squares, airport runways, and other road surfaces. The continuous eight-wheel road surface smoothness tester can continuously and automatically measure the road surface smoothness, greatly improving measurement efficiency.

[0003] The operator starts the equipment, and the sensors begin working. As the equipment moves forward at a constant speed, the sensors capture road surface information in real time and transmit the data to the processing system. The processing system instantly analyzes the data, generating precise values ​​and a detailed report on the road surface smoothness. After the inspection is complete, the equipment is shut down, ready for the next use.

[0004] In existing technologies, some convenient continuous eight-wheel road surface leveling instruments often leave stones after frequent use, causing bumpy rides during subsequent use and reducing work efficiency. Therefore, to address these shortcomings, a convenient continuous eight-wheel road surface leveling instrument is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a convenient continuous eight-wheel smoothness tester for highways, aiming to improve the problem that some existing eight-wheel smoothness testers experience bumps in the wheel hub due to the adhesion of stones, resulting in reduced work efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A convenient continuous eight-wheel road surface evenness tester includes a support frame and an eight-wheel evenness tester housing. A support mechanism is fixedly connected inside the support frame. Connecting frames are fixedly connected to both the left and right sides of the support frame. Driving mechanisms are fixedly connected to both the front and rear sides of the connecting frames. Adjustment mechanisms are rotatably connected to the front and rear ends of the bottom side of the connecting frames via base plates. Multiple adjustment mechanisms include right-angle plates, with adjacent sides of the right-angle plates fixedly connected to the opposite sides of the base plates. A rotating rod is rotatably connected inside the connecting frame. Limiting rings are fixedly connected to both the front and rear ends of the rotating rod. A wheel hub is fixedly connected to the outside of the rotating rod. A fixing block is fixedly connected to the bottom side of the connecting frame. An arc-shaped plate is rotatably connected to the outside of the fixing block via a pin. A reset assembly is fixedly connected to the top side of the arc-shaped plate.

[0008] The above technical solution involves: constructing the main frame through a support frame and a connecting frame; enhancing overall stability through a support mechanism; providing driving power through a drive mechanism; connecting the right-angle plate and the base plate in the adjustment mechanism to form a support foundation; rotating the rod to drive the wheel hub to rotate and detect the road surface; preventing axial displacement through a limit ring; and resetting the fixed block by hinged pins to the arc plate and resetting the assembly.

[0009] As a further description of the above technical solution:

Fixed rings are fixedly connected to both ends of the rotating shaft. Two force guide plates are fixedly connected to the outside of the fixed rings. A sliding plate is rotatably connected to the inside of the force guide plates through a rotating plate. Two limiting components are fixedly connected to adjacent sides of the plurality of sliding plates, and a clamping block is fixedly connected to the top side of the limiting components.

[0011] Through the above technical solution: the support mechanism is fixed inside the support frame by the support platform to provide basic support, the motor drives the rotating shaft to rotate the fixed ring, the force guide plate and the rotating plate work together to transmit the rotational force to the sliding plate, and the sliding plate restricts the movement trajectory through the limiting component and drives the clamping block to achieve positioning and clamping.

A cylinder is rotatably connected inside the open plate, and a concave plate is rotatably connected to the drive end of the cylinder.

[0014] The above technical solution provides support by fixing the drive mechanism to both sides of the connecting frame through the open plate, and the cylinder drives the concave plate to achieve reciprocating motion. This structure converts pneumatic power into mechanical motion, providing an adjustable propulsion force for the flatness meter.

[0015] As a further description of the above technical solution:

[0016] Both of the limiting components include a limiting plate on their exterior. The front and rear sides of the limiting plate are respectively fixedly connected to the adjacent side of the two sliding plates. A limiting rod is slidably connected inside the two limiting plates.

[0017] Through the above technical solution: the limiting component is connected to the sliding plates on both sides through the limiting plate to form a linkage structure, and the limiting rod slides inside the limiting plate to limit the range of motion, providing a stable guiding effect for the clamping block.

[0018] As a further description of the above technical solution:

[0019] The limiting rod is externally fixedly connected to the inside of the support mechanism, and the top side of the limiting plate is fixedly connected to the bottom side of the clamping block.

[0020] Through the above technical solution: the limiting rod is fixed inside the support mechanism to provide a rigid reference, and the top side of the limiting plate is connected to the bottom side of the clamping block to form a motion transmission. This structure realizes the precise guidance of the clamping block, and at the same time transmits the stability of the support mechanism to the clamping end, ensuring the linearity of pressure transmission and measurement accuracy during the flatness tester detection process.

[0021] As a further description of the above technical solution:

[0022] The two clamping blocks are respectively in contact with the left and right sides of the housing of the eight-wheel flatness tester. The top side of the support mechanism has two limiting openings, and the outside of the limiting plate is slidably connected to the inside of the limiting openings.

[0023] Through the above technical solution: the clamping block fixes the equipment by contacting both sides of the flatness tester housing, and the limiting opening on the top side of the support mechanism slides with the limiting plate to form a guide structure, ensuring the stable positioning of the flatness tester housing during the testing process.

[0024] As a further description of the above technical solution:

[0025] Each of the reset components includes a positioning ring, the bottom side of which is fixedly connected to the top side of the arc-shaped plate, a torsion spring is sleeved on the outside of the positioning ring, and a support ring is fixedly connected to the bottom side of the connecting frame.

[0029] Through the above technical solution: the grip achieves rotation limit through the connecting frame, and the support ring fixes the top of the torsion spring to form an elastic support point.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, dust and small stones attached to the connecting frame will be restrained by the arc plate and pressed against the limiting ring, thereby cleaning the dust and small stones, avoiding the presence of stones, preventing movement and bumps during subsequent use, and thus improving work efficiency; at the same time, the torsion spring in a stretched state pulls the positioning ring upward, thereby driving the arc plate to rotate around the fixed block 77 and tightly fit the triangular plate, thereby improving the cleaning effect.

[0032] 2. In this utility model, by driving two fixed guide plates to rotate, the rotational force is transmitted to the rotating plate, thereby driving the sliding plate to slide, which in turn drives the limiting plate to slide, and drives the two clamping blocks to move to the same side to fix and disassemble the housings of eight-wheel flatness testers of different sizes, thereby improving the flexibility and convenience of the device.

[0033] 3. In this utility model, the concave plate is rotated by starting the cylinder, which in turn drives the right-angle plate to rotate around the base plate, so that the whole device can achieve flat adjustment, so as to facilitate the detection of the housing of the eight-wheel flatness tester.

[0040] 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.

[0041] Reference Figures 1 to 2 This utility model provides an embodiment of a convenient continuous eight-wheel road surface smoothness tester, comprising a support frame 1 and an eight-wheel smoothness tester housing 8. The support frame 1 provides support force, and the eight-wheel smoothness tester housing 8 is used for smoothness detection. A support mechanism 2 is fixedly connected inside the support frame 1 to support the eight-wheel smoothness tester housing 8. The support mechanism 2 includes a support platform 21, which is externally fixedly connected to the inside of the support frame 1 and fixed by welding to provide support for the support platform 21. A motor 22 is fixedly connected to the rear end of the support platform 21 to provide a drive source. A rotating shaft 23 is fixedly connected to the drive end. The rotating shaft 23 is driven to rotate by the starting motor 22. Fixed rings 24 are fixedly connected to both ends of the rotating shaft 23. The rotating shaft 23 drives the two fixed rings 24 to rotate. Two force guide plates 25 are fixedly connected to the outside of the fixed rings 24. The force of the rotating shaft 23 is transmitted to the force guide plates 25 through the fixed rings 24. A sliding plate 27 is rotatably connected to the inside of the force guide plate 25 through a rotating plate 26. The rotating plate 26 is rotatably connected to the force guide plate 25 and the sliding plate 27, so that the force guide plate 25 can transmit the rotational force to the sliding plate 27, so that the sliding plate 27 can slide left and right.

[0042] Two limiting components 28 are fixedly connected to adjacent sides of multiple sliding plates 27. The sliding plates 27 drive the components to slide. Each limiting component 28 includes a limiting plate 2801 on its exterior. The top side of the limiting plate 2801 is fixedly connected to the bottom side of the clamping block 29. The limiting plate 2801 transmits the sliding force to the clamping block 29. The adjacent sides of the two clamping blocks 29 contact the left and right sides of the eight-wheel flatness meter housing 8, respectively. The two clamping blocks 29 slide towards the adjacent side and fix the eight-wheel flatness meter housing 8. Two limiting openings are opened on the top side of the support mechanism 2 to provide movement space for the limiting plate 2801. The limiting plate 2801 is externally slidably connected to the inside of the limiting opening, enabling the limiting plate 2801 to slide stably. The front and rear sides of the limiting plate 2801 are respectively fixedly connected to the adjacent side of the two sliding plates 27. The sliding force is transmitted to the limiting plate 2801 through the sliding plates 27. The limiting rod 2802 is slidably connected inside the two limiting plates 2801. The limiting rod 2802 provides guidance for the sliding of the limiting plate 2801. The limiting rod 2802 is externally fixedly connected to the inside of the support mechanism 2 and is fixed by welding process, thereby providing support for the limiting rod 2802. A clamping block 29 is fixedly connected to the top side of the limiting component 28.

[0043] Specifically, a support mechanism 2 is welded and fixed inside the support frame 1. This mechanism includes a support platform 21 on which a motor 22 is installed as a drive source. The motor 22 drives two fixed rings 24 to rotate via a rotating shaft 23. The guide plate 25 outside the fixed rings 24 converts the rotational motion into the left and right linear motion of the sliding plate 27 via a rotating plate 26. The sliding plate 27 is connected to a limiting component 28, which includes a limiting plate 2801 and a guiding limiting rod 2802. A clamping block 29 is fixed to the top of the limiting plate 2801. When the sliding plate 27 moves, it drives the limiting plate 2801 to slide along the limiting opening, ultimately causing the two clamping blocks 29 to move towards each other and clamp and fix the housing 8 of the eight-wheel flatness tester. This design achieves rapid clamping through mechanical linkage, which not only ensures the stability of the testing instrument but also improves the ease of operation.

[0044] Reference Figure 1 , Figure 3 and Figure 4The support frame 1 is fixedly connected to the left and right sides with connecting frames 3 by welding, thus providing support for the two connecting frames 3. A handle 6 is rotatably connected inside one of the connecting frames 3, allowing the connecting frame 3 to move. Drive mechanisms 5 are fixedly connected to the front and rear sides of the connecting frame 3. Multiple drive mechanisms 5 include open plates 51. The adjacent sides of two open plates 51 are fixedly connected to the front and rear sides of the connecting frame 3 by welding, thus providing support for the open plates 51. A cylinder 5 is rotatably connected inside the open plate 51. 2. The opening plate 51 and the cylinder 52 are connected by a pin, so that the cylinder 52 can rotate. The driving end of the cylinder 52 is rotatably connected to the concave plate 53, which is also rotated by a pin, so that the cylinder 52 can push the concave plate 53 to rotate. The bottom front and rear ends of the connecting frame 3 are rotatably connected to the adjustment mechanism 7 through the base plate 4 for adjusting the horizontal height. Each of the multiple adjustment mechanisms 7 includes a right angle plate 71. The adjacent sides of the multiple right angle plates 71 are respectively fixedly connected to the distant sides of the multiple base plates 4 and fixed by welding process, thereby providing support for the right angle plates 71.

[0045] A rotating rod 73 is rotatably connected inside the connecting frame 72. The connecting frame 72 restricts the rotation of the rotating rod 73. Limit rings 74 are fixedly connected to both ends of the rotating rod 73 via welding, providing support for the rotating rod 73. A hub 75 is fixedly connected to the outside of the rotating rod 73, facilitating movement of the entire device. A fixing block 77 is fixedly connected to the bottom side of the connecting frame 72 via welding, providing support for the fixing block 77. An arc-shaped plate 78 is rotatably connected to the outside of the fixing block 77 via pins, used to push stones to both sides. A reset assembly 79 is fixedly connected to the top side of the arc-shaped plate 78, providing a reset force. Multiple reset assemblies... Each component 79 includes a positioning ring 7901. The bottom side of the positioning ring 7901 is fixedly connected to the top side of the arc plate 78 by welding, thereby providing support for the positioning ring 7901. A torsion spring 7902 is sleeved on the outside of the positioning ring 7901. The torsion spring 7902 stores elastic potential energy and then applies a force in the opposite direction to the positioning ring 7901 to drive the arc plate 78 to rotate. A support ring 7903 is fixedly connected to the bottom side of the connecting frame 72 by welding, thereby providing support for the support ring 7903. The outside of the support ring 7903 is sleeved on the top of the torsion spring 7902, providing support for the torsion spring 7902 so that the torsion spring 7902 can be evenly stressed.

[0046] Specifically, in terms of the support structure, the connecting frames 3 welded on both sides of the support frame 1 and the rotatable handle 6 welded on one of the connecting frames facilitate the removal of the device. The drive system adopts a drive mechanism 5 arranged symmetrically at the front and rear. The cylinder 52 pushes the concave plate 53 to achieve the adjustment of the detection height, ensuring that the flatness meter can adapt to the measurement needs of different road conditions. The walking system includes an innovatively designed adjustment mechanism 7, whose hub 75 achieves smooth rolling through the rotating rod 73. The arc plate 78 set at the bottom, together with the reset component 79, constitutes an automatic obstacle avoidance mechanism. When encountering stones on the road, the arc plate is pressed and rotates to push away the obstacle, and automatically resets through the torsion spring 7902.

[0047] Working principle: By gripping and rotating the handle 6, the entire device is pulled to the detection position. Then, according to the tilt requirements of the device, the positions of multiple adjustment mechanisms 7 are adjusted. The cylinder 52 is started to drive the concave plate 53 to rotate, thereby driving the right-angle plate 71 to rotate around the base plate 4, so that it can achieve flat adjustment. At this time, the eight-wheel flatness tester housing 8 can be detected. When the eight-wheel flatness tester housing 8 needs to be replaced, the motor 22 is started to drive the rotating shaft 23 to rotate, thereby driving the two fixed rings 24 to rotate, which in turn drives the two fixed force guide plates 25 to rotate. The rotational force is then transmitted to the rotating plate 26, thereby driving the sliding plate 27 to slide, which in turn drives the limiting plate 2801 to slide, and drives the two clamping blocks 29 to move to the same side to fix and disassemble the eight-wheel flatness tester housing 8 of different sizes, thereby improving the flexibility of the device.

[0048] During the overall transfer process, the fixing ring 24 provides support and rotation to improve convenience. During the movement, the triangular plate 76 holds the stones against both sides, while the dust and small stones attached to the connecting frame 72 are restrained by the arc plate 78 and hold against the limiting ring 74, thereby cleaning the dust and small stones, preventing the stones from remaining, and preventing the problem of movement and bumps during subsequent use, thus improving work efficiency. At the same time, the torsion spring 7902 in a stretched state pulls the positioning ring 7901 to move upward, thereby driving the arc plate 78 to rotate around the fixing block 77 and tightly fit the triangular plate 76, thereby improving the cleaning effect. Furthermore, depending on whether the tire on the limiting ring 74 has a tread pattern, a cleaning block corresponding to the tire tread pattern can be welded to the bottom of the arc plate 78.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
