Description

TECHNICAL FIELD

[0001] The application relates to the technical field of highway engineering detection, in particular to a highway engineering compaction degree test detection device. BACKGROUND

[0002] During asphalt highway paving construction, asphalt raw materials need to be compacted by a road roller after paving. In order to detect whether the asphalt compaction meets the construction standard, drilling and sampling of the compaction thickness after compaction is a commonly used detection method, and multiple sample points need to be selected for drilling and sampling. The existing public technical field CN219568812U proposes a highway engineering compaction degree test detection device. The highway engineering compaction degree test detection device is provided with a sleeve on a flat plate, a moving plate is arranged on the sleeve, a motor is arranged on the moving plate, a rotating drum is arranged on the motor, and the rotating drum can be driven to rotate by the motor in use. The soil is collected in the rotating drum by drilling and taking soil on the surface of the rotating drum, so that the safety of the detection experiment device in use is greatly improved. At the same time, a bulldozing block is arranged in the rotating drum, so that the soil in the rotating drum can be quickly taken out. According to the related technology in the above, the practical new type person believes that the following defects still exist: the compaction degree test detection device in the comparative document can only sample one drilling sample at a time when multiple drilling and sampling are performed. For different wide asphalt highways, the same cross section of the asphalt highway needs to be sampled and compared, so as to achieve better detection data. This leads to the problem of slow single sampling efficiency. In view of this, a highway engineering compaction degree test detection device is proposed. CONTENT OF THE UTILITY MODEL

[0003] 1. Technical problem to be solved

[0004] The purpose of the present application is to provide a highway engineering compaction degree test detection device, which solves the technical problem of slow single sampling efficiency caused by the fact that the compaction degree test detection device in the comparative document in the above background technology can only sample one drilling sample at a time when multiple drilling and sampling are performed. For different wide asphalt highways, the same cross section of the asphalt highway needs to be sampled and compared, so as to achieve better detection data. The technical effect of the present application is realized by pushing the detection device to different detection positions, sampling two samples at the same time according to the compaction width of the road surface by using two adjustable distance sampling mechanisms, and accurately sampling and detecting the compaction of different wide asphalt road surfaces. In the drilling and sampling process, the generated smoke dust can be sucked and purified by a purification tank, so as to ensure the construction environment and reduce the physical harm of smoke dust to the construction detection personnel.

[0011] By adopting the above technical solution, the electric cylinder is rotatably hinged with the hinge seat and the slide seat. When the piston rod of the electric cylinder extends or retracts, the slide seat can slide up and down along the vertical rail.

[0012] Optionally, the width adjusting mechanism comprises a worm, the worm is rotatably installed on the T-shaped guide frame, the worm is in meshing connection with a worm wheel, the worm wheel is fixedly provided with a bidirectional screw rod, both ends of the bidirectional screw rod are rotatably connected with support blocks, and the support blocks are fixedly connected with the two elongated barrels respectively.

[0013] By adopting the above technical scheme, when the worm rotates, the worm wheel rotates through the bidirectional screw rod, the two support blocks move synchronously and reversely due to the opposite screw thread directions at both ends of the bidirectional screw rod, and then the two elongated barrels move synchronously and reversely.

[0014] Optionally, the upright rail is fixedly provided with a slope support on each side, and the slope support is attached to the upper surface of the bottom plate at the bottom end.
