[0018] The pressing and grinding mechanism includes a trapezoidal plate 25 arranged at the telescopic end of one of the first cylinders 14, an insertion rod 30 is inserted and installed inside the trapezoidal plate 25, and a fixed grinding disc 29 is fixedly arranged at one end of the insertion rod 30 away from the trapezoidal plate 25, and both ends of the trapezoidal plate 25 are provided with limit members; like Figure 5 , Figure 6 and Fig.11 As shown, under the telescopic drive of one of the first cylinders 14, the trapezoidal plate 25 can drive the fixed grinding disc 29 and the insertion rod 30 to move toward one end of the concrete core rod until the fixed grinding disc 29 contacts the concrete core rod to grind its end.

[0019] The end face clamping mechanism includes a ring frame 8, the outer side of the ring frame 8 is connected to the first cylinder 14 away from one end of the trapezoidal plate 25, the inner side of the ring frame 8 is fixedly installed with a No. 1 motor 7, the output end of the No. 1 motor 7 is fixedly provided with an end face positioning platform 35, the outer side of the end face positioning platform 35 is rotatably installed with a clamping frame 31, the outer edge of one side of the clamping frame 31 is connected to the outer side of the ring frame 8 through a plurality of support rods 33, and the outer sides of the outer wall of the clamping frame 31 are connected to the grinding components through the provided connecting components; like Figure 1 , Figure 2 , Figure 5 , Figure 7 As shown, the No. 1 motor 7 can drive the end surface positioning platform 35 corresponding to the front end to rotate, so that the end surface positioning platform 35 can rotate when it is stuck against one end of the concrete core rod, so that the outer surface and one end of the concrete core rod can be polished at the same time.

[0020] The connecting assembly includes a connecting block 34 fixedly arranged on one side of the outer wall of the bracket 31, the interior of the connecting block 34 is connected to the movable rod 28 via a rotatably installed rotating shaft, and the grinding assembly is arranged outside the movable rod 28; like Figure 7 As shown, under the connection of the connection block 34 , the grinding assembly can be arranged outside one end of the movable rod 28 for use.

[0021] The grinding assembly includes a grinding roller 16, which is sleeved on the outside of the movable rod 28; like Figure 5 As shown, the grinding roller 16 can be placed parallel to one side of the concrete core rod under the sleeve of the movable rod 28 to perform coordinated grinding work, and it is convenient to operate.

[0022] The limiting member includes a screw barrel 26 fixedly mounted on one end of the trapezoidal plate 25, the screw barrel 26 is threadedly connected with the screw rod 15, a connecting barrel 32 is rotatably sleeved at one end of the screw barrel 26 and located at the screw rod 15, and a rotating rod 27 is rotatably sleeved at one end of the connecting barrel 32 away from the screw rod 15, the connecting barrel 32 and the screw barrel 26 are slidably matched, and the rotating rod 27 and one end of the grinding roller 16 are rotatably opposed; like Figure 5 , Figure 6 , Figure 7 , Fig. 9 As shown, the screw 15 inside the screw barrel 26 can rotate in coordination, and the rotating rod 27 at its front end moves toward the front end. When the fixed grinding disc 29 contacts one end of the concrete core rod, the rotating rod 27 can be locked with the end of the grinding roller 16 at one end.

[0023] A vertical rod 13 is fixedly arranged on the upper part of the ring frame 8, a sliding frame 38 is fixedly installed on the outer side of the vertical rod 13, a sliding frame 39 is slidably installed on the outer side of the sliding frame 38, a clamping block 42 is slidably installed on the lower part of the sliding frame 39, a second cylinder 37 is arranged on the outer side of the clamping block 42, the second cylinder 37 is fixedly installed on the outer side of the vertical rod 13 and is located below the sliding frame 38, and push rods 40 are vertically installed on both sides of the outer wall of the sliding frame 39, and a T-shaped plate is commonly set on the upper part of the two push rods 40, and a sliding rod 17 is slidably inserted inside the T-shaped plate, and the lower end of the sliding rod 17 is fixedly arranged on the upper surface of the sliding frame 39, and a spring 41 is set on the outer side of the sliding rod 17 and located below the T-shaped plate, and a connecting rod 12 is arranged on the outer wall of the sliding frame 39 and away from the second cylinder 37, and a limiting wheel 36 is symmetrically arranged on the outer side of the connecting rod 12; like Figure 8 As shown, under the telescopic drive of the second cylinder 37, the block 42 drives the slide frame 38 to move to one end, and then pulls the slide rod 17 so that the slide rod 17 drives the slide frame 39 to move upward, prompting the limiting wheel 36 to pass over the bracket 31, so that the limiting wheel 36 can be pressed against the upper surface of the concrete core rod, and then when the concrete core rod rotates, it can cooperate with the rotation to get in position on the top.

[0024] The pushing mechanism includes a screw rod 11 rotatably mounted on the inner side of the vertical frame 9, a No. 2 motor 10 is arranged on the upper end of the screw rod 11, and the No. 2 motor 10 is fixedly mounted on the upper surface of the vertical frame 9. The external thread of the screw rod 11 is matched with a slide 18, and a base 22 is symmetrically arranged on the upper surface of one end of the slide 18. A loading fence 21 is vertically mounted on the upper surface of both groups of bases 22, and an arc-shaped elastic plate 23 is fixedly arranged on the upper end of one group of the loading fences 21. A frame 3 is fixedly arranged on the lower surface of the slide 18, and a hydraulic cylinder 4 is fixedly installed inside the frame 3. The telescopic end of the hydraulic cylinder 4 slides and extends to the top of the slide 18 and a push plate 24 is arranged at the end; like Figure 1 , Figure 2 , Figure 4 and Fig.12 As shown, the No. 2 motor 10 is started to drive the screw 11 to rotate. With the rotation of the screw 11, the threaded slide 18 slides inside the vertical frame 9, thereby lifting the multiple concrete core rods to be inspected and polished that are clamped in the two sets of material fences 21. Then, under the push of the hydraulic cylinder 4, the push plate 24 pushes the multiple groups of concrete core rods to move upward, causing the top concrete core rod to be pushed out from above and contact the surface of the arc-shaped elastic plate 23. Under the guidance of the elastic plate 23, the concrete core rod is squeezed out from one side, and then the worker places it above the two sets of rotating seats 20 for processing.

[0025] Working principle: When in use, the concrete core rod to be tested and polished can be placed above the two sets of rotating seats 20, and then the movable rods 28 on both sides of the bracket 31 rotate toward the outer surfaces of the concrete core rod on both sides, so that the grinding roller 16 is parallel to the concrete core rod, and then the first cylinder 14 at the lower end of the trapezoidal plate 25 drives the trapezoidal plate 25 and the fixed grinding disc 29 to move toward one end of the grinding roller 16 until the outer surface of the fixed grinding disc 29 contacts and abuts against one end of the concrete core rod, and the screw 1 inside the corresponding screw barrel 26 is pressed against the screw rod 16. The rotation drives the connecting tube 32 and the rotating rod 27 to approach the end of the grinding roller 16 and abut against it, so that the grinding roller 16 and the concrete core rod are clamped. At the same time, the first cylinder 14 on one side of the clamping frame 31 pushes the end surface positioning platform 35 to abut against the other end of the concrete core rod. When the end surface positioning platform 35 contacts the concrete core rod, the sliding frame 38 on the outer side of the vertical rod 13 also moves toward one end with the movement of the clamping frame 31. The second cylinder 37 can push the sliding frame 39 to approach the upper surface of the concrete core rod, and pull up the sliding rod 1 7, so that the slide frame 38 can be lifted upward, so that the limit wheel 36 can pass over the bracket 31 and roll and fit on the outer surface of the concrete core rod, so as to ensure that the concrete core rod can be more stable during grinding. The first motor 7 drives the end surface positioning platform 35 to rotate, driving the concrete core rod to rotate. One end of the concrete core rod rubs against the surface of the fixed grinding disc 29, and the outer surface rolls with the grinding rollers 16 on both sides. As a result, during the rotation process, one end and the outer surface of the concrete core rod can be polished at the same time. Inside the vertical frame 9 The concrete core rod to be polished can be placed between the two sets of loading fences 21 above the slide 18. Driven by the No. 2 motor 10 and the screw rod 11, the slide 18 moves upward, and the hydraulic cylinder 4 drives the push plate 24 to move upward, so that the uppermost concrete core rod contacts the elastic plate 23. Under the guidance of the elastic rebound of the elastic plate 23, the concrete core rod cooperates with the worker's operation to place it inside the two sets of rotating seats 20, so as to complete the operation of automated batch loading and reduce the burden of workers taking and placing back and forth.

[0026] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only examples of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention to be protected.
