Description

Technical Field

[0001] The utility model relates to the technical field of concrete sampling, in particular to concrete sampling equipment used in water conservancy project sites. Background Art

[0002] Concrete drilling sampling equipment used at water conservancy project sites is primarily used to obtain representative samples from concrete structures. The design and operation of this type of equipment directly impacts the quality of sampling and the accuracy of the results. Drilling holes in concrete structures and obtaining core samples are used for quality testing and assessment of concrete's compressive strength, impermeability, and other indicators.

[0003] If the concrete drilling sampler lacks a guardrail around it during operation, it will bring a series of safety hazards and potential problems. During the drilling sampling process, the rotating drill bit and the splashing materials generated during the work may injure the operator or bystanders. Without guardrails, personnel may easily enter the working area by mistake, increasing the safety risk of the work site. During the drilling sampling, noise, dust, wastewater and other pollutants may be generated. Without guardrails, these pollutants are more likely to spread to the surrounding environment, affecting the surrounding environment and personnel. In view of the above defects, the present utility model is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a concrete sampling device for use at a water conservancy project site, so as to solve the problem that during the drilling sampling process, the rotating drill bit and the splashes generated during the work may injure the operator or bystanders, and there are no protective railings, so people may easily mistakenly enter the working area, increasing the safety risks at the work site.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: a concrete sampling device for use at a water conservancy project site, comprising a concrete drilling sampling device body, the concrete drilling sampling device body being provided with a drilling mechanism, the drilling mechanism being provided with a drill bit, a first protective member being movably connected to an outer wall of a bottom end of the concrete drilling sampling device body, second protective members being connected to both side walls of the concrete drilling sampling device body, and a limit member being provided on a side wall of the first protective member;

The two groups of the second protective members and the first protective member form a closed space, and the limiting member fixes the second protective member and the first protective member.

[0007] Preferably, the first protective member includes a movable inner cavity opened in the main body of the concrete drilling sampling device, a movable plate connected to the inner wall of the movable inner cavity, a first baffle connected to the outer wall of the movable plate, a threaded rod threadedly connected to the side wall of the main body of the concrete drilling sampling device, and a threaded groove opened in the movable plate.

[0008] Preferably, the movable plate and the first baffle are combined into an L-shape, and the movable plate is connected to slide back and forth in the movable inner cavity.

[0009] Preferably, the thread grooves are symmetrically arranged on the side walls at both ends of the movable plate, and the diameter of each group of movable plates is set to be equal to the inner diameter of the thread grooves.

[0010] Preferably, the second protective member includes two groups of fixed plates connected to the side walls of the concrete drilling sampling device body, a rotating shaft rotatably connected between the two groups of fixed plates, and a second baffle sleeved on the rotating shaft.

[0011] Preferably, the second baffles are symmetrically arranged in two groups, and each group of the second baffles is rotatably connected to the fixed plate via a rotating shaft.

DETAILED DESCRIPTION

[0027] The following further illustrates the above and other technical features and advantages of the present invention in conjunction with the accompanying drawings and embodiments. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive. Example

[0028] like Figure 1-6 As shown, the utility model provides a concrete sampling device for water conservancy project construction sites, including a concrete drilling sampling device body 1, a drilling mechanism 2 is provided on the concrete drilling sampling device body 1, a drill bit 3 is provided on the drilling mechanism 2, a first protective member 4 is movably connected to the outer wall of the bottom end of the concrete drilling sampling device body 1, second protective members 5 are connected to the two side walls of the concrete drilling sampling device body 1, and a limit member 6 is provided on the side wall of the first protective member 4;

[0029] The first protective member 4 is slidably connected in the main body 1 of the concrete drilling sampling device, and the second protective member 5 is symmetrically connected in two groups. The two groups of second protective members 5 and the first protective member 4 form a closed space, and the limit member 6 fixes the second protective member 5 and the first protective member 4.

[0030] The first protective member 4 includes a movable inner cavity 41 defined within the main body 1 of the concrete drilling and sampling device, a movable plate 42 connected to the inner wall of the movable inner cavity 41, a first baffle 43 connected to the outer wall of the movable plate 42, a threaded rod 44 threadedly connected to the side wall of the main body 1 of the concrete drilling and sampling device, and a threaded groove 45 defined within the movable plate 42.

[0031] The second protective member 5 includes two sets of fixed plates 51 connected to the side walls of the concrete drilling sampling device body 1, a rotating shaft 52 rotatably connected between the two sets of fixed plates 51, and a second baffle 53 sleeved on the rotating shaft 52;

[0032] Before the worker starts the drilling mechanism 2 to work, he first pulls the first baffle 43 outward, so that the first baffle 43 drives the thread groove 45 to move to the position of the threaded rod 44, and then tightens the threaded rod 44 inward, so that the threaded rod 44 and the threaded groove 45 are engaged and fixed, and then rotates the second baffles 53 at both ends, so that the two groups of second baffles 53 rotate on the fixed plate 51 through the rotating shaft 52, until the two groups of fixed plates 51 rotate and fit together with the first baffle 43 to form a closed space, which completely wraps the drill bit 3, allowing the drill bit 3 to perform sampling work in the space;

[0033] Among them, the combined shape of the movable plate 42 and the first baffle 43 is set to be L-shaped. This design can form a stable supporting structure inside the first protective member 4. The L-shape helps to improve the stability and supporting force of the overall structure. The movable plate 42 is connected by sliding back and forth in the movable inner cavity 41. This sliding design enables the movable plate 42 to be easily moved and positioned, and is also convenient for the operator to disassemble the movable plate 42.

[0034] The thread grooves 45 are symmetrically formed on the sidewalls of both ends of the movable plate 42, which ensures a more stable connection between the movable plate 42 and the threaded rod 44 during the sliding process, thereby avoiding instability or damage caused by excessive pressure on one side. The diameter of each set of movable plates 42 is set to be equal to the inner diameter of the thread groove 45, which ensures that the movable plate 42 is more tightly fixed on the threaded rod 44, thereby improving the overall fixation and sealing performance.

[0035] The second baffles 53 are symmetrically arranged in two groups, each group being rotatably connected to the fixed plate 51 via a rotating shaft 52. This symmetrical design makes the structure more balanced and improves overall work efficiency and stability. Each group of second baffles 53 is rotatably connected to the fixed plate 51 via a rotating shaft 52. In this way, the position of the second baffles 53 can be easily adjusted to meet the needs of different working environments without interfering with the first protective member 4.

[0036] The bottom end of the second baffle 53 is higher than the bottom end of the concrete drilling sampling device body 1. The rotation of the second baffle 53 will not affect the first protective member 4. This design ensures that the rotation of the second baffle 53 will not cause collision and obstruction to the threaded rod 44, thereby ensuring the continuity and safety of the work.

[0037] The limiting member 6 includes a base 61 connected to the outer wall of the first baffle 43, two sets of mounting plates 62 symmetrically connected to the base 61, a long shaft 63 rotatably connected to the mounting plates 62, and a limiting plate 64 connected to the outer wall of the long shaft 63;

[0038] After the first baffle 43 and the two groups of second baffles 53 are fitted together, the staff can rotate the limit plate 64 so that the limit plate 64 rotates on the mounting plate 62 through the long axis 63 until the limit plate 64 engages with the outer walls of the two groups of second baffles 53 to form a fixed position, thereby ensuring that the space formed after the first baffle 43 and the two groups of second baffles 53 are fitted together is stable.

[0039] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, and all of these changes will fall within the scope of protection of the present invention.
