Description

Technical Field

[0001] The utility model relates to the technical field of highway detection, in particular to a detection device for highway construction. Background Art

[0002] Highway refers to a public road between cities, between urban and rural areas, and between villages that can be used for automobiles and has been accepted and approved by the transportation authority. It includes highways that have been built and approved by the transportation authority. It should also include highways that are designed in accordance with national highway engineering technical standards, approved by relevant national administrative departments and are under construction by the transportation authority. During the construction of the highway, it is necessary to inspect the construction quality, so a highway construction inspection device is required.

[0003] A Chinese patent application with the authorization publication number CN217111763U discloses a highway construction inspection device. The device comprises a workbench, a fixed frame mounted above the workbench, a hydraulic telescopic rod mounted on the frame, and a pressure block mounted at the bottom of the hydraulic telescopic rod. A support seat is fixedly mounted in the middle of the workbench, a pressure detection module is located in the middle of the support seat, and a sample block is mounted on the pressure detection module. The workbench has grooves symmetrically formed on the left and right sides of the upper portion. A first slide bar is located in the upper portion of the grooves, and a second slide bar is located in the lower portion of the grooves. A slider is slidably connected to the first and second slide bars. A movable plate is fixed above the sliders. A first spring is mounted on the outer wall of the first slide bar, on the side of the slider away from the sample block. The device is easy to use and can effectively improve inspection accuracy compared to traditional equipment, minimizing the impact of external conditions on accuracy.

[0004] Although the above-mentioned highway construction detection device can effectively improve the detection accuracy and minimize the impact of external conditions on the accuracy compared with traditional equipment, it only uses a hydraulic telescopic rod to drive the pressure detection module to perform downward pressure detection on the sample. The sample can only be detected from static pressure. The highway is bumpy during use and is easily affected by the vibration force from the car, resulting in inaccurate detection. For this reason, we propose a detection device for highway construction. Utility Model Content

[0005] The purpose of the present utility model is to provide a detection device for highway construction, so as to solve the problem proposed in the above background technology that since the sample is pressed down by the pressure detection module driven by the hydraulic telescopic rod, the sample can only be detected from the static pressure, while the road is bumpy during use and is easily affected by the vibration force from the car, thereby causing inaccurate detection.

A pressure head is installed in the middle below the lifting plate;

[0008] A fixed seat is installed on the other side above the detection platform, with lifting push rods installed at both ends of the fixed seat, and a lifting block is connected above the lifting push rods, and limit rods are installed at both ends of the lifting block;

[0009] A driving motor is installed on one side of the lifting block. A turntable is connected to one side of the driving motor, and rotating rods are installed on both sides of the turntable. One end of the rotating rod is connected to a knocking block.

[0010] Preferably, a telescopic structure is formed between the lifting hydraulic cylinder and the lifting plate, and the pressure head and the lifting plate are perpendicular to each other, and the positions of the pressure head and the limit seat correspond to each other.

[0011] Preferably, the limiting seat is further provided with:

[0012] A nut seat is installed below the limit seat, a transmission screw is installed inside the nut seat, and one end of the transmission screw is connected to a transmission motor.

[0013] Preferably, a rotating structure is formed between the transmission motor and the transmission screw, and the transmission screw passes through the interior of the nut seat, and the nut seat is fixedly connected to the limit seat.

[0014] Preferably, a telescopic structure is formed between the lifting push rod and the lifting block, and the limiting rod is slidably connected to the lifting block.

[0015] Preferably, a rotating structure is formed between the driving motor and the turntable, and the rotating rods are symmetrically distributed about the horizontal center line of the turntable, and the knocking block is fixedly connected to the rotating rods.

[0016] Compared with the prior art, the present invention provides a detection device for highway construction, which has the following beneficial effects:

[0017] The utility model can drive the turntable, the rotating rod and the knocking block to select by the driving motor, so that when the knocking block is rotated to the position of contact with the sample, the road sample can be knocked by the knocking block, simulating the impact force received by the road during the bumping process, avoiding the problem of only driving the pressure detection module to perform downward pressure detection on the sample by the hydraulic telescopic rod, in which the sample can only be detected from the static pressure, while the road is still bumpy during use and is easily affected by the vibration force from the car, thereby causing the problem of inaccurate detection.
