Description

Technical Field

[0001] This utility model relates to the field of engineering supervision technology, specifically an engineering supervision sampler. Background Technology

[0002] Engineering supervision refers to a professional service activity in which a qualified supervision unit, entrusted by the client, monitors the construction of a project on behalf of the client, in accordance with the nationally approved project construction documents, relevant laws and regulations on engineering construction, engineering construction supervision contracts and other engineering construction contracts. In this process, a sampler is required for sampling. Such a sampler can be referenced with patent number: 202123335873.2.

[0003] Conventional engineering supervision samplers can only sample the surface of building materials, resulting in limited sampling results. Furthermore, the process of retrieving the samples is cumbersome, which affects the overall sampling efficiency. Therefore, there is a need for an engineering supervision sampler that can sample building materials at different depths and facilitates sample retrieval. Utility Model Content

The inside of the first fixing block is movably connected to the outer surface of the first drive rod, and the inside of the second fixing block is movably connected to the outer surface of the rotating rod. The first fixing block and the second fixing block respectively serve to support the first drive rod and the rotating rod, so that the lifting structure can operate stably.

[0010] Preferably, a third fixing block is fixedly connected to the bottom of the lifting platform. The interior of the third fixing block is movably connected to the outer surface of the second drive rod.

[0013] Compared with the prior art, this utility model provides an engineering supervision sampling device with the following beneficial effects:

[0014] 1. Traditional engineering supervision samplers can only sample the surface of building materials, and the process of retrieving the sample is cumbersome and inefficient. This invention addresses this by activating a servo motor and a drive motor to move a rotating drill bit downwards using two threaded blocks. The drill bit can then be drilled to the corresponding depth for sampling. After the drill bit finishes running, the connecting cylinder can be removed by loosening the fixing bolts, and the sampling cylinder can be retrieved by rotating the external threaded cover. The sample in the sampling slot can then be taken out for testing.

[0015] 2. This sampler integrates the functions of sampling building materials at different depths and conveniently retrieving the samples after sampling. The sampler has adjustment slots on opposite sides of the two lifting shells. After the servo motor is started, the adjustment slots can limit the threaded block, allowing it to stably drive the lifting platform to move up and down. The sampler has casters installed at the bottom of the base plate, which can move the entire sampler to the required position. After reaching the position, step on the foot brake to make the sampling process more stable. Attached Figure Description

[0024] Working principle: First, push the push rod 29 to move the universal wheel 30 to the required position. After reaching the position, press the foot brake 31 to fix the entire sampler. Then, start the drive motor 14 to make the second drive rod 15 drive the lower connecting cylinder 18 to rotate. Then, start the servo motor 5 and control it to rotate forward. The first bevel gear 7 on the first drive rod 6 drives the rotating rod 9 and the threaded rod 11 to rotate together through the second bevel gear 8.

At this time, the fixing bolt 17 is loosened and the connecting cylinder 18 is removed through the sleeve block 16. Then, the external thread cover 21 is rotated to pull the sampling cylinder 22 out of the connecting cylinder 18, and the sample in the sampling slot 23 can be taken out for testing.
