AI Technical Summary
Existing concrete road quality testing devices are time-consuming and labor-intensive during the testing process. Once the testing rod falls into the crack, it cannot automatically reset and needs to be manually pulled out.
The device employs a structure consisting of a mounting housing, a reset component, multiple detection rods, and rollers. The rollers are connected to the reset component via a transmission mechanism. As the rollers roll, the reset component applies an upward force to the detection rods, causing them to automatically reset. Combined with a drive motor, this enables automatic movement and detection.
It saves time and effort in the process of inspecting the quality of concrete roads. The test rod automatically detaches from the grout and does not need to be manually pulled out, thus improving the inspection efficiency.

Abstract
Description
Technical Field
[0001] This application relates to the field of road surface testing technology, and in particular to a concrete road quality testing device. Background Technology
[0002] After a period of time, concrete roads will suffer varying degrees of damage or deformation, resulting in cracks of all sizes on the road surface. If not dealt with in time, this can lead to serious consequences. In particular, during the rainy season, water seeps into the road surface and soaks it, reducing its load-bearing capacity. Over time, this can cause large-scale damage to the road surface, rendering it unusable.
[0003] Existing concrete road quality testing devices generally include a mobile frame and multiple testing rods. Each testing rod is set vertically, and the multiple testing rods are arranged in a row along the width of the road. Each testing rod is slidably connected to the mobile frame and can slide freely up and down, so that when the mobile frame moves along the length of the road, the testing rods above the cracks will automatically fall into the cracks, thus alerting the testing personnel.
[0004] However, because the testing rod is restricted by the grout after it falls into the crack, the moving frame cannot continue to move forward to test the remaining road surface. The testing personnel must first manually keep the testing rod in the pulled-out state and then move the moving frame away from the grout, which makes the testing process of the concrete road quality testing device time-consuming and labor-intensive.
[0005] Therefore, there is a need to provide a concrete road quality testing device. Utility Model Content
[0006] To address the problem of time-consuming and labor-intensive testing processes in existing concrete road quality testing devices, this application provides a concrete road quality testing device.
[0007] This application provides a concrete road quality testing device, which adopts the following technical solution: it includes a mounting shell, a reset component, multiple testing rods and multiple rollers. A row of limiting through holes is opened on the mounting shell along the vertical direction. The testing rods correspond one-to-one with the limiting through holes. Each testing rod is inserted into the corresponding limiting through hole and can slide up and down along the limiting through hole.
[0008] Each of the rollers is located at the bottom of the mounting housing, and the wheel surface of each roller can abut against the road surface;

[0013] When the reset rod abuts against the top surface of the roller, the bottom end of the detection rod can be inserted into the crack on the road surface through the reset waist-shaped hole, and when the reset rod abuts against the top edge of the roller, the reset rod can abut against the limiting member upwardly and make the bottom end of the detection rod not lower than the road surface.

[0015] Further, the limiting member is a nut, and an external thread matched with the limiting member is arranged on the rod body of the detection rod below the horizontal rod.
[0016] By adopting the above technical scheme, the nut can be detachably connected with the detection rod through cooperation with the external thread, so that the user can conveniently assemble the concrete road quality detection device.

[0018] By adopting the above technical scheme, the clamping plate can be combined with the inner wall of the sleeve to form the limiting through hole, thereby limiting the detection rod in the horizontal direction.
[0019] Further, a limiting rod is arranged on the side of the clamping plate away from the limiting groove, and a limiting hole is arranged on the sleeve.
[0020] By adopting the above technical scheme, the limiting rod can cooperate with the limiting hole to limit the clamping plate, so as to prevent the clamping plate from falling out of the sleeve.
[0021] Further, the crossbar further comprises a clamping bolt, a threaded hole leading to the inside of the sleeve is arranged on the outer side wall of the sleeve, the clamping bolt is screwed with the threaded hole, and the screw end of the clamping bolt is rotatably connected with the clamping plate through the threaded hole and can drive the clamping plate to approach or move away from the detection rod, when the clamping plate approaches the detection rod, the clamping plate and the detection rod are abutted between the clamping bolt and the inner wall of the sleeve.
[0022] By adopting the above technical scheme, the clamping bolt can drive the clamping plate to approach and abut the detection rod between the clamping plate and the inner wall of the sleeve, so as to fix the position of each detection rod, thereby facilitating the user to pick up the concrete road quality detection device for measurement.
[0023] Specifically, the bottom end of each detection rod is provided with a ball.
[0024] By adopting the above technical scheme, the arrangement of the ball can reduce the friction between the detection rod and the road surface, and facilitate the movement of the concrete road quality detection device on the road surface.
[0025] Specifically, a driving motor is further arranged, the driving motor is in transmission connection with the roller and can drive the roller to rotate.

[0038] The working principle of the concrete road quality detection device in use is as follows:
[0039] When detecting the road surface, the user can drive the installation housing 1 to move along the length direction of the road by starting the driving motor 5, when one or more detection rods 3 pass above the crack, the detection rods 3 will fall, at this time the user can close the driving motor 5 and judge the specific situation of the crack by the number of the falling detection rods 3 and the falling depth of each detection rod 3; after recording the required data, the user can continue to drive the installation housing 1 to move along the length direction of the road by starting the driving motor 5, when the top edge of the roller 4 abuts against the reset rod, the reset rod will move upward and lift all the detection rods 3 in the crack out of the crack, so that the user does not need to manually pull the detection rods 3 out of the crack, thereby saving time and labor in the detection process of the concrete road quality detection device;
[0040] Of course, in order to avoid the situation that the detection rod 3 just passes above the crack when the top edge of the roller 4 abuts against the reset rod, and then the detection rod 3 cannot fall into the crack, causing detection error, the user can use the concrete road quality detection device for multiple reciprocating detection on the same road section, so as to effectively avoid detection error.
