Description

Technical Field

[0001] The utility model relates to the technical field of road surface detection, in particular to an asphalt road surface engineering detection device. Background Art

[0002] Pavement smoothness is a key indicator in pavement evaluation and construction acceptance. It refers to the deviation in longitudinal concavity and convexity on the road surface, primarily reflecting the smoothness of the pavement's longitudinal cross-section curve. Uneven pavement surfaces increase driving resistance, impacting driving safety and comfort. They also impact the pavement, reducing its service life.

[0003] In the prior art, the patent with announcement number CN117867937A discloses an asphalt pavement engineering detection device, and the following scheme is proposed, which includes a frame and a brush, a main control module is fixedly installed on the top of the frame, an infrared sensor is fixedly installed on the bottom of the frame, a marking component is fixedly installed on the frame, and a bracket is fixedly connected to the top of the frame. A rectangular ring is fixedly connected to the left end of the bracket, a rectangular rod is slidably connected to the rectangular ring, a pull ring is fixedly connected to the left side of the rectangular rod, and a plurality of slots are evenly spaced on the right side of the rectangular rod. A positioning component is provided on the top of the bracket. The present invention realizes the height adjustment of the brush through a simple structure, and can fold the brush when the detection device is not in use, avoiding contact friction between the brush and the ground, reducing unnecessary wear, increasing the service life of the brush, reducing replacement frequency and maintenance cost, and can facilitate disassembly and replacement of the brush, convenient for personnel to operate and use, and highly practical.

[0004] However, the above technical solution still has the following shortcomings when in use: in the above device, the brush needs to be driven by a drive motor, which means that it needs to be plugged in when in use, which is inconvenient. In fact, the brush lacks a protective mechanism, and when encountering larger stones during the movement, it is easy to collide with the brush and cause damage to the brush. In this regard, we have proposed an asphalt pavement engineering inspection device to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide an asphalt pavement engineering detection device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an asphalt pavement engineering detection device, comprising:

[0007] The top end face of the lifting post is fixedly mounted on the lifting post, and the bottom end face of the lifting post is fixedly mounted on the lifting post, and the second lifting post is meshed with the first gear and the second gear.

[0008] Preferably, two L-shaped rods are fixedly welded on the movable seat, the two L-shaped rods are arranged on both sides of the brush, mounting rods are fixedly welded on the two L-shaped rods, and buffer baffles are arranged on the mounting rods.

[0009] Preferably, a buffer damper is fixedly mounted on the buffer baffle, one end of the two buffer dampers away from the buffer baffle is mounted on a mounting rod, and a buffer spring is sleeved on the two buffer dampers.

[0010] Preferably, a sliding rod is fixedly mounted on the top wall of the brush, the sliding rod is slidably connected to the second rotating column, and a locking stud is threadedly connected to the second rotating column.

[0011] Preferably, a push handle is fixedly mounted on the movable seat.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. During use, when the movable seat moves, the front rotating rod rotates, and the front rotating rod can drive the first rotating column to rotate through the meshing cooperation of the first bevel gear and the second bevel gear. The first rotating column can drive the second rotating column to rotate on the L-shaped mounting frame through the transmission cooperation of the first pulley, the second pulley and the transmission belt, thereby driving the brush to rotate for cleaning. This realizes that when the movable seat is manually pushed forward, the brush can be driven to rotate for cleaning, without the need for an additional motor to drive, which is more energy-efficient.

[0014] 2. The buffer baffle of the utility model can protect the brush and prevent large stones from colliding with the brush. It can also push large stones to both sides of the device during the movement of the device. The impact force of the stone can be buffered by the provided buffer damping and buffer spring to avoid vibration of the entire device due to excessive impact force.
