Description

Technical Field

[0001] This utility model relates to the field of detection and sampling technology, and in particular to an engineering test detection and sampling device. Background Technology

[0002] In the construction of buildings, roads, and other engineering projects, sand and gravel are core components of concrete and base materials. Their particle size distribution, mud content, and crushing value directly determine the strength, durability, and stability of the engineering structure. Therefore, representative sampling and testing of sand and gravel is a crucial step in engineering quality control.

[0003] Currently, sand and gravel sampling is generally done manually with shovels, where operators use shovels to directly dig up the surface material of the sand and gravel pile. This method has low technical barriers and low costs, but it is limited by the working range and depth of the shovel, and can only collect the surface material of the sand and gravel pile, unable to reach different layers inside. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, sand and gravel sampling is generally carried out by manual shovels, and operators can usually only sample the surface of sand and gravel with a handheld shovel. Therefore, an engineering test and detection sampling device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an engineering test and sampling device, comprising a cylinder, a cylinder fixedly connected to the bottom of the cylinder, a circular groove formed at the bottom of the cylinder, an inner column embedded inside the circular groove, a sampling groove formed on the surface of the inner column, a push rod slidably connected through the inside of the cylinder, one end of the push rod passing through the cylinder and fixedly connected to the inner column, and a fixing sleeve fitted and fixedly connected to the surface of the cylinder near the top, with push handles fixedly connected to both ends of the fixing sleeve.

[0006] Preferably, a conical block is fixedly connected to the bottom of the inner column.

[0007] Preferably, the outer arc wall of the inner column is symmetrically provided with limiting grooves, and each limiting groove is embedded in and slidably connected with a limiting plate, and each limiting plate is fixedly connected to the inner wall of the circular groove.

[0008] Preferably, the cylinder has an arc-shaped hole on its surface, and a transparent plate is fixedly connected inside the arc-shaped hole.

[0009] Preferably, a handle is fixedly connected to the top of the push rod.

[0010] Preferably, the surface of the push handle is fitted with and fixedly connected with a rubber sleeve.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the conical block at the bottom of the cylinder is easy to insert into the sand and gravel pile, and the sampling groove of the inner column can extend out of the circular groove under the action of the push rod to take samples deep into the sand and gravel pile, so as to obtain samples of different depths and layers, making the test results more consistent with the actual material quality.

[0012] 2. In this utility model, the limiting groove and the limiting plate cooperate to ensure that the inner column slides stably along the circular groove and avoids deviation during the sampling process; the push handle and the rubber sleeve provide a comfortable grip and force application point, which facilitates manual operation for insertion and removal.

[0013] 3. In this utility model, the transparent plate inside the arc hole allows direct observation of the sand and gravel filling in the sampling groove, and the sampling amount can be determined without the need for a pull-out device, thus improving sampling efficiency and accuracy.

A fixing sleeve 13 is sleeved and fixedly connected to the surface of the cylinder 1 near the top. Both ends of the fixing sleeve 13 are fixedly connected to the push handle 14, which can facilitate pushing the cylinder 1.

[0020] Example 2, as Figure 1-4 As shown, a conical block 6 is fixedly connected to the bottom of the inner column 4; the outer arc wall of the inner column 4 is symmetrically provided with limiting grooves 7, and limiting plates 8 are embedded and slidably connected inside the limiting grooves 7, and the limiting plates 8 are fixedly connected to the inner wall of the circular groove 3; an arc hole 9 is provided on the surface of the cylinder 2, and a transparent plate 10 is fixedly connected inside the arc hole 9; a handle 12 is fixedly connected to the top of the push rod 11; and a rubber sleeve 15 is fitted and fixedly connected to the surface of the push handle 14.

[0021] The overall effect of Embodiment 2 is as follows: the conical block 6 is fixedly connected to the bottom of the inner column 4, which facilitates the embedding of the conical block 6 into the sand and gravel; the inner column 4 has symmetrically opened limiting grooves 7 on its outer arc wall, and each limiting groove 7 has a limiting plate 8 embedded and slidably connected inside, and each limiting plate 8 is fixedly connected to the inner wall of the circular groove 3, which can limit the inner column 4; the circular column 2 has an arc hole 9 on its surface, and a transparent plate 10 is fixedly connected inside the arc hole 9, which can facilitate the observation of the inside of the sampling groove 5; the push rod 11 has a handle 12 fixedly connected to its top, which can facilitate the pushing of the push rod 11; and the push handle 14 has a rubber sleeve 15 fixedly connected to its surface, which can prevent slipping.

Using the conical block 6 at the bottom of the cylinder 2, the operator inserts the device into the sand and gravel pile. At this time, the sampling groove 5 of the inner column 4 is embedded in the circular groove 3 of the cylinder 2. Then, the operator holds the handle 12 and pushes the push rod 11 downward. The push rod 11 drives the inner column 4 to slide along the circular groove 3. The limiting groove 7 on the outer arc wall of the inner column 4 moves synchronously along the limiting plate 8 to maintain stability, so that the sampling groove 5 extends out of the circular groove 3 and embeds itself into the sand and gravel. After the sampling groove 5 is filled, the operator pulls the handle 12 upward. The push rod 11 drives the inner column 4 to reset, and the sampling groove 5 retracts into the circular groove 3, carrying the sand and gravel sample.
