Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of concrete sampling, in particular to a concrete sampling device. Background Art
[0002] Testing the compressive strength of concrete is very important to ensure the structural safety of buildings. Insufficient strength may lead to serious consequences such as cracks, deformation, and even collapse during the use of the building. For concrete that has been poured, core drilling rigs are generally used to extract core columns from the concrete building for sample testing and analysis.
[0003] When sampling a core column with an existing concrete sampling device, when the sample is on the ground, the drill can be accurately drilled perpendicular to the ground. When the sample is on a wall, the sampling device is generally fixed to the wall and the drill is positioned at the sampling location. However, it is difficult to fix the sampling device on the wall, which often causes a certain deviation in the sampling position of the drill, making it impossible to accurately sample. Therefore, to address the above problems, we have proposed a concrete sampling device. Utility Model Content
[0004] In view of the above problems, the purpose of the present invention is to provide a concrete sampling device, which is convenient for performing appropriate adjustment according to the position of coring and reducing the position deviation during sampling.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a concrete sampling device, including a drill body and a telescopic support frame, a receiving groove is provided on the drill body, a telescopic part 1 is movably connected in the receiving groove, a slide groove is provided on the inner wall of the receiving groove, a slide seat is slidably connected in the slide groove, the movable end of the telescopic part 1 is hinged to the slide seat, fixed blocks are provided at both ends of the top of the telescopic support frame, a rotating rod is rotatably connected between the two fixed blocks, and one end of the drill body is connected to the rotating rod.
[0006] The beneficial effects of the present invention are as follows: the sampling device as a whole is supported and fixed by the telescopic support frame; according to the sampling position required, the fixed end of the telescopic part 1 is taken out of the receiving groove and fixed on the ground; the height of the telescopic part 1 and the telescopic support frame is adjusted according to the sampling position required, so that the drilling rig body can be accurately aligned with the sampling position, which increases the convenience of the sampling device and reduces the position deviation during sampling.

When the sampling position is higher, the telescopic part 2 can be extended and retracted in height to facilitate the transportation of the drilling rig body to the appropriate position.
[0010] In order to fix the rotating rod to prevent it from rotating;
[0011] As a further improvement of the above technical solution: a fixing screw is threadedly connected to the fixing block, and the fixing screw is used to fix the rotating rod.
[0012] The beneficial effect of this improvement is that when sampling is carried out, the fixing screw is tightened, and one end of the fixing screw presses against the rotating rod, thereby fixing the rotating rod and working together with the telescopic member to increase the stability of the drilling rig body.
[0013] In order to increase the stability of the telescopic member;
[0014] As a further improvement of the above technical solution: the fixed end of the telescopic member 1 is connected to a support seat.
[0015] The beneficial effect of this improvement is that when the telescopic member 1 is used, the telescopic member 1 is taken out from the accommodating groove, and then the support seat contacts the ground, thereby increasing the contact area with the ground and improving the stability of the telescopic member 1.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.
[0030] like Figure 1-6 As shown, the concrete sampling device includes a drill body 1 and a telescopic support frame. The drill body 1 is provided with a receiving groove 2, and a telescopic member 3 is movably connected in the receiving groove 2, wherein the telescopic member 3 can be an electric telescopic rod, a hydraulic telescopic rod, etc. A slide groove 4 is provided on the inner wall of the receiving groove 2, and a slide seat 5 is slidably connected in the slide groove 4. The movable end of the telescopic member 3 is hinged to the slide seat 5. Before use, the slide seat 5 is located at one end of the slide groove 4, and then the telescopic member 3 is retracted to the shortest length and stored in the receiving groove 2. When in use, the fixed end of the telescopic member 3 is taken out to contact the ground. , to support the drill body 1, both ends of the top of the telescopic support frame are provided with fixed blocks 7, and a rotating rod 8 is rotatably connected between the two fixed blocks 7. One end of the drill body 1 is connected to the rotating rod 8. When in use, the telescopic support frame reinforces the overall support. The height of the telescopic support frame and the telescopic part 3 are adjusted according to the sampling position so that the drill body 1 can remain perpendicular to the sampling surface. If the sampling requires inclined sampling, when adjusting the height of the telescopic part 3, the slide 5 slides in the slide groove 4, so that the inclination angle of the drill body 1 can be accurately adjusted, which is convenient for use and reduces the position deviation during sampling.
[0031] Furthermore, the telescopic support frame includes a telescopic part 2 601 connected to the bottom of the two fixed blocks 7 and a base 602 connected to the bottom of the two telescopic parts 2 601, wherein the telescopic part 2 601 can be an electric telescopic rod, a hydraulic telescopic rod, etc., which can be adjusted in height according to the sampling position, and the base 602 can increase the contact area with the ground, thereby increasing the overall support fixity of the team.
[0032] Furthermore, a fixing screw 9 is threadedly connected to the fixing block 7, and the fixing screw 9 is used to fix the rotating rod 8, wherein the fixing screw 9 can be provided on both fixing blocks 7, which can increase the fixing effect of the rotating rod 8. When sampling is performed, the fixing screw 9 is tightened, and one end of the fixing screw 9 is pressed against the rotating rod 8, thereby fixing the rotating rod 8, which works together with the telescopic member 3 to increase the stability of the drilling rig body 1.
[0033] Furthermore, the fixed end of the telescopic member 3 is connected to the support seat 10. When the telescopic member 3 is used, the telescopic member 3 is taken out from the accommodating groove 2, and then the support seat 10 contacts the ground, increasing the contact area with the ground and improving the stability of the telescopic member 3.
[0034] Furthermore, scale lines 11 are provided on both sides of the drill body 1, and an identification strip 12 corresponding to the position of the scale line 11 is provided on the rotating rod 8. During actual use, the scale line 11 and the identification strip 12 can be painted with a more eye-catching color to increase the visual effect, which is more intuitive when observed by users. When the drill body 1 is sampling, it is adjusted according to the drilling position and angle, and the position of the identification strip 12 on the scale line 11 is determined to increase the accuracy of the drill body 1 in drilling the core column.
[0035] Furthermore, a plurality of universal brake wheels 13 are provided at the bottom of the base 602. The universal brake wheels 13 are provided with brake pads, which can be moved at will. The universal brake wheels 13 can be fixed by the blocking effect of the brake pads to prevent the universal brake wheels 13 from moving. The setting of the universal brake wheels 13 can facilitate the movement of the device to a suitable position for use. At the same time, after moving to a suitable position, the position can be fixed by the universal brake wheels 13 to avoid displacement.
[0036] The working principle and usage process of the present invention: When using this equipment, first move the device to a suitable position through the universal brake wheel 13, and then determine the sampling position. If the sampling position is on the wall and the sampling is vertical, first adjust the drill body 1 to a state perpendicular to the wall, rotate the drill body 1 upward, and then observe the position of the identification bar 12 and the scale line 11, and tighten the fixing screw 9 so that the fixing screw 9 is pressed against the rotating rod 8 to fix the drill body 1, and then remove the telescopic part 13 from the accommodating groove 2, so that the support seat 10 is in contact with the ground and fixed, and then adjust the height of the telescopic part 13 and the telescopic part 2 601 at the same time. After the drill body 1 moves to the sampling position, align it with the sampling point to perform drilling sampling. If it is necessary to sample the wall at an angle, loosen the fixing screw 9, release the fixation of the rotating rod 8, and then adjust the length of the telescopic part 13 to tilt the drill body 1, observe the position of the identification bar 12 to determine the angle of inclination, and accurately sample.
