Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a convenient engineering detection sampling device. Background Art

[0002] Concrete pouring is often used in existing construction projects. Concrete piles in construction projects are important pressure-bearing components in construction projects. The quality of concrete piles directly affects the quality of engineering buildings. Therefore, concrete piles in construction projects need to be tested after construction is completed, and the commonly used testing method is sampling testing.

[0003] Core sampling is a simple, intuitive and high-precision local damage detection method, which is widely used in concrete pile quality inspection. At present, concrete core sampling is mainly done by manually operating a concrete core sampling device. During the sampling process, the sampling device manually pushes the high-speed rotating drill bit into the concrete and removes the drilled concrete block to complete the core sampling work.

[0004] For example, a concrete core sampling tool disclosed in the patent document with application number 202123436662.8, when core sampling concrete, first fix the drill bit of appropriate size on the sampling motor, and then fix the entire tool on the sampling concrete pile through a fixing plate. Then, the sampling motor is controlled to rotate by a control mechanism, and the rotation of the sampling motor drives the drill bit to rotate at high speed. At the same time, the sampling motor drives itself to slide toward the concrete on the guide rail through the transmission mechanism, and the drill bit drills into the concrete pile. This type of equipment is a typical core sampling equipment. Although this type of equipment can perfectly solve the sampling problem, there are still some shortcomings in the sampling process, which are mainly manifested in: in the sampling drilling process, this type of equipment will use water flow to prevent dust from being generated, but the sewage generated during the drilling process will pollute the pile surface, and as the drilling depth increases, the sewage cannot be collected uniformly and will flow to the ground, which is not conducive to the cleanliness of the construction environment. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a convenient engineering inspection sampling device which can keep the construction clean and avoid sampling stains.

[0007] Furthermore, a clearance gap is provided at the lower part of the substrate, and the clearance gap is connected to the sampling hole so that the lower half of the sampling hole is open.

[0008] Furthermore, limiting grooves for limiting the sewage collection box are arranged on both sides of the avoidance gap.

[0009] Furthermore, the sewage collection box comprises a box body, the box body is provided with a through hole adapted to a drill bit of a sampling drill, and a circle of extension pipes is provided around the through hole on one side of the box body.

[0010] Furthermore, the end of the extension tube is wedge-shaped, and the inclined surface of the wedge faces the inside of the through hole.

[0011] Furthermore, a protrusion matched with the limiting groove is arranged on the outer side of the box body, and a stepped groove matched with the avoiding notch is arranged on one side of the box body so that the box body can be snapped on the avoiding notch.

[0012] Furthermore, a flow guide nozzle is provided at the bottom of the box body, and the flow guide nozzle is connected to the flow guide pipe.

During the drilling process of the sampling drill rig, sewage flows into the sewage collection box through the drill hole for collection.

[0024] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0025] like Figure 1-6 As shown, the portable engineering inspection sampling device includes a fixed plate 1, a guide rail 2 and a driving drill, the guide rail 2 is connected to the fixed plate, and the sampling drill 3 is arranged on the guide rail 2 and can move along the guide rail 2. In this embodiment, the connection between the sampling drill 3 and the guide rail 2 is relatively mature in the market, and the movement is mostly achieved by using the principle of gears and racks, which will not be described in detail here. The fixed plate 1 includes a base plate 11, a sampling hole 12 provided below the base plate 11 and facing the drill bit 31 of the sampling drill 3, and a sewage collection box 5 arranged in the sampling hole 12, and the bottom of the sewage collection box 5 is connected to a diversion pipe for draining sewage.

[0026] The portable engineering inspection sampling device comprises a sampling hole 12 provided on a base plate 11 and corresponding to a sampling drill 3, a sewage collection box 5 is arranged in the sampling hole 12 and a drainage pipe is connected to the bottom of the sewage collection box 5, during the drilling process of the sampling drill 3, sewage flows into the sewage collection box 5 through the drilling hole for collection, and if the drilling depth is deep, the sewage can be led to the collection device by connecting the drainage pipe. The portable engineering inspection sampling device of the utility model collects sewage through the sewage collection box 5 during the drilling process, and drains the sewage through the drainage pipe, which can keep the construction clean, and at the same time can prevent sewage from flowing down along the pile surface, and avoid leaving stains after sampling.

[0027] The base plate 11 has a lower portion provided with an avoidance notch 13 , which is connected to the sampling hole 12 so that the lower half of the sampling hole 12 is open. Limiting grooves 14 for limiting the sewage collection box 5 are provided on both sides of the avoidance notch 13 .

[0028] The avoidance notch 13 can effectively reduce the overall weight of the base plate 11 , and can also effectively fix the position of the sewage collection box 5 by using the avoidance notch 13 to prevent the sewage collection box 5 from rotating during the drilling process of the drill 31 .

[0029] The sewage collection box 5 includes a box body, which is provided with a through hole 51 adapted to the drill bit 31 of the sampling drill rig 3, and a circle of extension tubes 52 is arranged around the through hole 51 on one side of the box body. A diversion nozzle 55 is arranged at the bottom of the box body, and the diversion nozzle 55 is connected to the diversion tube. In this embodiment, the material of the box body is plastic, and in some other embodiments, it can also be made of other materials. The end of the extension tube 52 is wedge-shaped, and the inclined surface of the wedge faces the inside of the through hole 51. The wedge shape is convenient for sewage to enter the inside of the box body from the extension tube 52. After the drill bit 31 drills a shallow groove on the pile, the drill bit 31 is pulled out and the box body is put into position, and then the box body can be drilled again.

[0030] The outer side of the box body is provided with a protrusion 53 adapted to the limiting groove 14, and one side of the box body is provided with a stepped groove 54 adapted to the avoiding notch 13 so that the box body can be snapped on the avoiding notch 13 to achieve a stable fixed connection of the sewage collection box 5.
