Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, specifically to a multi-purpose concrete drilling and sampling machine. Background Technology

[0002] A concrete drilling and sampling device is a piece of equipment used for sampling and testing concrete. It typically consists of a drilling rig, drill bit, drill rod, core sampler, etc. Publication number CN221764943U discloses a concrete drilling and sampling device, belonging to the field of concrete drilling and sampling technology. This concrete drilling and sampling device includes a mounting frame and a vehicle body. The mounting frame rotates on one side of the vehicle body. The sampling mechanism includes a servo motor, which is fixed inside the mounting frame. A lead screw is fixedly installed at the output end of the servo motor. This invention utilizes the interaction of the servo motor, lead screw, fixed frame, motor, main gear, secondary gear, spiral blade, and sampling box. First, the servo motor is started, driving the lead screw to rotate. The lead screw moves the fixed frame downwards. At this time, the starting motor drives the main gear to rotate, which in turn drives the secondary gear to rotate, thereby driving the fixed rod and spiral blade to rotate and drill a hole in the concrete. After completion, the servo motor is started in reverse to move the fixed frame upwards. During this movement, the electric telescopic rod is controlled to move the sampling box, thereby collecting deeper concrete.

[0003] However, as the complexity of building structures increases, concrete buildings with complex conditions such as inclined surfaces and curved surfaces will appear, which puts forward higher requirements for the multi-functionality, portability and automation of the sampling machine. Although the device is highly convenient and easy to sample deep concrete, it is not convenient to sample concrete with inclined surfaces and curved surfaces, and its adaptability is low.

[0004] Therefore, it is necessary to invent a multi-purpose concrete drilling and sampling machine to solve the above problems. Utility Model Content

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] This utility model provides, for example Figures 1 to 3 The multi-purpose concrete drilling and sampling machine shown includes an equipment support 1. A connecting frame 13 is fixedly connected to the left side of the equipment support 1. A mounting base 2 is slidably connected to the surface of the connecting frame 13. A threaded rod 14 is threadedly connected to the surface of the equipment support 1 at the right side of the connecting frame 13. An adjusting wheel 15 is fixedly connected to the right end of the threaded rod 14. A first connecting block 22 is fixedly connected to the inner wall of the left side of the mounting base 2. The first connecting block 22 is rotatably connected to the left end of the threaded rod 14. A counterweight plate 11 is fixedly connected to the right side of the lower end of the equipment support 1. Multiple sets of universal wheels 12 are rotatably connected to the lower side of the counterweight plate 11. A sampling component is installed on the front side of the mounting base 2.

[0034] The caster wheel 12 has a self-locking mechanism on its surface. After the equipment is moved to the sampling point, the caster wheel 12 is locked by the self-locking mechanism to prevent the equipment from moving during the sampling process. Then, the counterweight is placed on the surface of the counterweight plate 11 to press the equipment, which further improves the stability of the equipment during use. The threaded rod 14 can be rotated. When the threaded rod 14 rotates clockwise, it will push the mounting seat 2 to the left in conjunction with the first connecting block 22. Conversely, rotating the threaded rod 14 counterclockwise will push the mounting seat 2 to the right, adjusting the position of the mounting seat 2 so that the sampling equipment is close to the sampling point. After the adjustment is completed, the sampling equipment is used to sample and test the concrete.

[0035] See Figures 3 to 5The sampling assembly includes a limiting groove 23, a limiting slider 24, a locking tooth 25, an adjusting screw 26, a second connecting block 27, an adjusting plate 3, a locking groove 31, a linear guide rail 32, a linear slider 33, a mounting block 34, a progress motor 35, a drill rod 36, a sampling drill bit 37, and a pressure rod 38. The adjusting plate 3 is rotatably connected to the front surface of the mounting base 2. Limiting grooves 23 are provided on both sides of the front surface of the mounting base 2 on the left and right sides of the adjusting plate 3. Limiting sliders 24 are slidably connected inside both sets of limiting grooves 23. The adjusting screw 26 is threadedly connected to the side wall of the limiting groove 23. The second connecting block 27 is fixedly connected to the side surface of the limiting slider 24 away from the adjusting plate 3. One end of the adjusting screw 26 is rotatably connected to the second connecting block 27. Multiple sets of locking grooves 31 are provided on the side of the adjusting plate 3. Multiple sets of locking teeth 25 are fixedly connected to the side surface of the limiting groove 23 near the adjusting plate 3.

[0036] In addition, during the sampling process, the angle of the sampling drill bit 37 can be adjusted by rotating the adjustment disc 3, so that the sampling drill bit 37 is perpendicular to the sampling point of the inclined or curved concrete, so as to sample the surface of the inclined or curved concrete and improve the detection accuracy.

[0037] Meanwhile, after the angle of the sampling drill bit 37 is adjusted, the adjusting screws 26 on both sides are rotated clockwise. The adjusting screws 26, together with the second connecting block 27, slide the limiting slider 24 to one side of the adjusting plate 3 and lock the locking tooth 25 into the locking groove 31 to lock and fix the adjusting plate 3, thereby fixing the angle of the sampling drill bit 37 and improving the stability during the sampling process.

[0038] See Figure 4 and Figure 5 Two sets of linear guide rails 32 are fixedly connected to the front surface of the adjusting plate 3, and two sets of linear sliders 33 are fixedly connected to the rear side of the mounting block 34. The linear sliders 33 are slidably connected to the linear guide rails 32. Pressure rods 38 are fixedly connected to both the left and right sides of the mounting block 34. The advance motor 35 is fixedly installed on the upper side of the mounting block 34. The drill rod 36 is rotatably connected to the inside of the mounting block 34. The upper end of the drill rod 36 is fixedly connected to the output end of the advance motor 35. The sampling drill bit 37 is fixedly connected to the lower end of the drill rod 36.

[0039] Specifically, during the sampling process, the advance motor 35 is started, and the output end of the advance motor 35 drives the drill rod 36 to rotate. The lower end of the drill rod 36 drives the sampling drill bit 37 to rotate. At the same time, the operator presses the drill rod 36 and the sampling drill bit 37 downward through the pressure rod 38 to drill a hole and sample the concrete surface. As the sampling drill bit 37 moves downward, the linear slider 33 slides downward on the surface of the linear guide rail 32 to prevent the sampling drill bit 37 from tilting during the sampling process, thus improving the sampling accuracy and the precision of the test data.

[0040] The working principle of this utility model is as follows: The mounting base 2 can slide left and right on the surface of the connecting frame 13 to adjust the left and right position of the sampling component. At the same time, the angle of the sampling component can be adjusted by rotating the adjusting plate 3. The adjusting plate 3 is locked and fixed by two sets of limiting sliders 24 and adjusting screws 26, which improves the stability during the sampling process. Meanwhile, the linear slider 33 slides up and down on the surface of the linear guide rail 32, which improves the stability of the mounting block 34, the advance motor 35 and the sampling drill bit 37 during the sampling process and improves the sampling accuracy. The linear slider 33 can slide out from the inside of the linear guide rail 32, which facilitates the disassembly and transportation of the equipment.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
