Description

Technical Field

[0001] This utility model relates to the technical field of concrete strength testing equipment, and in particular to a concrete strength testing equipment for municipal roads. Background Technology

[0002] During the use of municipal roads, due to vehicle load and environmental factors, concrete may suffer from fatigue damage, cracking, and deformation, and even serious collapse and fracture. Concrete strength testing can promptly identify potential problems on the road, prevent and avoid road collapse and fracture accidents, and ensure the safety and stability of the road. The existing method for testing the concrete strength of municipal roads is to use a core sampling machine. The core sampling machine rotates in the concrete through an internal drill bit and removes a core block.

[0003] A search revealed Chinese Patent Publication No. CN216746847U, which discloses a core sampling machine for concrete structures in highway engineering. The machine includes a frame with a base plate. One side of the base plate has a first concave groove, and the other side has a second concave groove. The first and second concave grooves are symmetrically distributed. A sliding column is located in the middle of the base plate, between the first and second concave grooves. A fixing plate is fixedly connected to the bottom of the sliding column. The advantages of this invention are: the support plate ensures the stability and convenience of the device; the water tank and outlet pipe effectively reduce the labor intensity of workers; the first concave groove significantly improves the safety of the device; the clamping device reduces manual clamping labor and improves work efficiency; and the top cover effectively increases the service life of the device. However, in actual use, existing core sampling machines are semi-automatic. After drilling and sampling, workers need to manually remove the core sample from inside the drill bit or the borehole, which is cumbersome. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a concrete strength testing device for municipal roads, aiming to improve the problem in the prior art that after drilling and sampling, staff need to manually remove the sample core block from inside the drill bit or the borehole.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a concrete strength testing device for municipal roads, comprising a base plate and a sleeve, wherein a telescopic rod is fixedly connected to the inner side of the base plate, and an elastic net is fixedly connected to one end of the telescopic rod. A groove is formed on the inner side of the base plate, and the outer wall of the elastic net is slidably connected to the inner side of the groove. Telescopic rods are fixedly connected to the front and rear sides of the base plate, and connecting plates are fixedly connected to adjacent sides of the two telescopic rods. A rotating shaft is fixedly connected to the outer wall of the two connecting plates, and connecting plates are fixedly connected to the outer wall of the two rotating shafts. The left and right sides of the elastic net are fixedly connected between adjacent connecting plates. Support rods are fixedly connected to the front and rear sides of the top of the base plate, and sliding plates are slidably connected to the outer walls of the two support rods. Sliding plates are slidably connected to the top ends of the two support rods. A striking mechanism is provided at the bottom of the sliding plates.

[0006] Through the above technical solution: the sleeve, in conjunction with the servo motor, can quickly rotate and cut into the concrete for core sampling, improving core sampling efficiency. Compared with traditional methods, it can obtain concrete core samples in a shorter time, providing timely samples for strength testing. The elastic net can flexibly extend from the groove to the bottom of the sleeve through the first telescopic rod, accurately receiving the sample core blocks that fall out of the sleeve. This design ensures the integrity of the sample during the extraction process, avoiding sample loss and damage. The combination of the second telescopic rod, the first connecting plate, the rotating shaft, and the second connecting plate can adjust the expansion and contraction of the elastic net.

[0007] As a further description of the above technical solution:

[0008] The striking mechanism includes two servo motors, each with a rotating rod fixedly connected to its output end. A pulley is fixedly connected to the top of the outer wall of each rotating rod. Multiple rotating rods are rotatably connected to the inner side of the sliding plate. A pulley is fixedly connected to the top of the outer wall of each rotating rod. A belt connects the pulley and the pulley. A cylinder is fixedly connected to the bottom of the outer wall of each rotating rod and the rotating rod. Multiple striking rods are fixedly connected to the outer wall of each cylinder.

[0009] Through the above technical solution: two servo motors provide powerful force to ensure stable and high-speed rotation of the rotating rod. Through the transmission system of pulley one, belt strip and pulley two, the power can be evenly transmitted to multiple rotating rods three, so that the striking rods on all cylinders rotate synchronously and strike the sleeve in an all-round and regular manner.

[0010] As a further description of the above technical solution:

[0011] The top of the base plate is fixedly connected to a fixing ring, and the tops of the two fixing rings are fixedly connected to the bottom of the corresponding support rod.

[0012] The above technical solution provides a more stable support for the support rod by fixing the top ring of the base plate to the bottom of the support rod.

[0013] As a further description of the above technical solution:

[0014] The top of the two fixing rings has multiple through holes.

[0015] The above technical solution involves fixing the bolts through through holes.

[0016] As a further description of the above technical solution:

[0017] A servo motor is fixedly connected to the top of the sliding plate 2, and a rotating rod is fixedly connected to the output end of the servo motor 1.

[0018] Through the above technical solution:

[0019] As a further description of the above technical solution:

[0020] A fixing plate is fixedly connected to the bottom of the rotating rod, and a sleeve is fixedly connected to the bottom of the fixing plate. The bottom of the sleeve is provided with serrations.

[0021] The above technical solution allows the serrated design at the bottom of the sleeve to cut into the concrete more efficiently for core extraction.

[0022] As a further description of the above technical solution:

[0023] A load-bearing plate is fixedly connected to the outer wall of the sliding plate.

[0024] The above technical solution is used to house the power source that supports the sliding of skateboard one and skateboard two.

[0025] As a further description of the above technical solution:

[0026] The tops of the two support rods are fixedly connected to baffles, and the bottoms of the two baffles are slidably connected to sliding plates.

[0027] The above technical solution prevents the sliding plate from falling off by using a baffle.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the elastic net is moved to the bottom of the sleeve by unfolding the first telescopic rod, and the width of the elastic net is adjusted by unfolding the second telescopic rod, so that the sample core block falls into the elastic net when it falls off. This fully automated design reduces the manual intervention and improves the continuity and efficiency of the core extraction operation.

[0030] 2. In this utility model, the servo motor drives the rotating rod to rotate, and the power is transmitted to multiple rotating rods through the cooperation of the pulley, belt and pulley. This transmission method can quickly and stably transmit power to each striking rod, so that the striking rods can strike the sleeve in a regular manner. Compared with the traditional manual striking method, it greatly improves the speed of sample core block detachment and reduces sampling time. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] See attached document Figure 1 Appendix Figure 3 and attached Figure 4 This utility model provides an embodiment of a concrete strength testing device for municipal roads, comprising a base plate 1 and a sleeve 15. A telescopic rod 3 is fixedly connected to the inner side of the base plate 1, and an elastic net 5 is fixedly connected to one end of the telescopic rod 3. A groove 4 is formed on the inner side of the base plate 1, and the outer wall of the elastic net 5 is slidably connected to the inner side of the groove 4. When sampling, it can retract into the base plate 1, thus not occupying extra space and not affecting normal sampling. Telescopic rods 6 are fixedly connected to the front and rear sides of the base plate 1. Connecting plates 7 are fixedly connected to adjacent sides of the two telescopic rods 6. Rotating shafts 8 are fixedly connected to the outer walls of the two connecting plates 7, and connecting plates 9 are fixedly connected to the outer walls of the two rotating shafts 8. The elastic net 5 is fixed to the left and right sides. Connecting the two adjacent connecting plates 9, the top front and rear sides of the base plate 1 are fixedly connected to the support rods 10, the outer walls of the two support rods 10 are slidably connected to the sliding plates 20, the top ends of the two support rods 10 are slidably connected to the sliding plates 21, and the bottom of the sliding plates 20 is provided with a striking mechanism 2; the top of the sliding plates 21 is fixedly connected to the servo motor 12, the output end of the servo motor 12 is fixedly connected to the rotating rod 13; the bottom of the rotating rod 13 is fixedly connected to the fixing plate 14, the bottom of the fixing plate 14 is fixedly connected to the sleeve 15, and the bottom of the sleeve 15 is provided with serrations 16, which, in conjunction with the servo motor 12 driving the rotating rod 13 to rotate, can quickly and efficiently cut into the concrete to extract the core sample, greatly shortening the core extraction time;

[0040] Specifically, the sleeve 15 in the equipment has serrations 16 at the bottom, which, together with the servo motor 12, drive the rotating rod 13 to rotate, enabling it to quickly and efficiently cut into the concrete to extract the core sample, greatly shortening the core extraction time. After the sleeve 15 completes the core extraction, the elastic net 5 can be quickly moved below the sleeve 15 and unfolded by controlling the telescopic rod 3 and the telescopic rod 6, ready to receive the sample core block. The whole process is convenient to operate, reduces the waiting time in the detection process, and improves the detection efficiency. The telescopic rod 6 on the front and rear sides of the base plate 1 can drive the connecting plate 7 to move, and the connecting plate 9 can be rotated through the rotating shaft 8, thereby adapting to the contraction and unfolding of the elastic net 5. The servo motor 12 is model SMA-PUC02D.

[0041] See attached document Figure 2 and attached Figure 5The striking mechanism 2 includes two servo motors 201, the output ends of which are fixedly connected to rotating rods 202. A pulley 203 is fixedly connected to the top of the outer wall of each of the two rotating rods 202. Multiple rotating rods 206 are rotatably connected to the inner side of the sliding plate 20. A pulley 204 is fixedly connected to the top of the outer wall of each of the two rotating rods 206. A belt strip 205 connects the pulleys 203 and 204. A cylinder 207 is fixedly connected to the bottom of the outer walls of the two rotating rods 202 and the rotating rods 206. Multiple striking rods 208 are fixedly connected to the outer walls of the cylinders 207. This mechanism can continuously strike the sleeve 15, causing the sample core block inside the sleeve 15 to receive more comprehensive vibration, further improving the speed and success rate of sample core block detachment.

[0042] Specifically, two servo motors 201 provide powerful force to ensure that the rotating rod 202 can rotate at high speed and stably. The rotating rod 202 drives the pulley 1 203 to rotate, and transmits the power to the pulley 204 through the belt 205, so that multiple rotating rods 206 rotate synchronously, so that the striking rod 208 contacts the sleeve 15 and can generate a continuous and uniform striking force, effectively causing the sample core block inside the sleeve 15 to fall off quickly. The model of the servo motor 201 is CMP50M.

[0043] See attached document Figure 1 and attached Figure 2 The top of the base plate 1 is fixedly connected with a fixing ring 17, which provides a more stable support base for the support rod 10, ensuring that the support rod 10 will not easily shake or tilt due to external forces during equipment operation, thereby ensuring the stability of the entire equipment structure. The tops of the two fixing rings 17 are fixedly connected to the bottoms of the corresponding support rods 10. Multiple through holes 18 are opened on the tops of the two fixing rings 17. The outer wall of the sliding plate 1 20 is fixedly connected with a load-bearing plate 11. The tops of the two support rods 10 are fixedly connected with baffles 19, and the bottoms of the two baffles 19 are slidably connected with sliding plate 21. The baffles 19 limit and guide the sliding plate 21.

[0044] Specifically, the fixing ring 17 strengthens the connection between the support rod 10 and the base plate 1. The baffles 19 at the top of the two support rods 10 limit and guide the sliding plate 21. The baffles 19 prevent the sliding plate 21 from detaching from the support rods 10 during the up and down sliding process, ensuring that the sliding plate 21 always runs on the correct track. At the same time, the baffles 19 also provide a certain support force for the sliding plate 21, sharing some of the weight and external force, further enhancing the overall stability of the equipment.

[0045] Working principle: Sliding plates 20 and 21 are moved downwards along the support rod 10. Servo motor 12 is started, and its output drives rotating rod 13 to rotate. Rotating rod 13 drives fixed plate 14 and bottom-fixed sleeve 15 to rotate. Since sleeve 15 has serrations 16 at its bottom, the rotating serrations cut into the concrete. Through rotation and downward pressure, the concrete core sample is gradually extracted. After the sleeve 15 completes core extraction, servo motor 12 is stopped. At this time, telescopic rod 3 is extended, moving the elastic net 5, originally placed in groove 4, to below sleeve 15. The telescopic rods 6 on both sides extend the net, facilitating the receipt of the sample core block from sleeve 15. Servo motor 201 is then started. The output of servo motor 201 drives rotating rod 202 to rotate. The pulley 203 on the top of the outer wall of rotating rod 202 rotates together with rotating rod 202. The pulley 203 transmits power to pulley 204 through belt 205, which drives rotating rod 3 206 fixedly connected to it to rotate inside sliding plate 20. As rotating rod 202 and rotating rod 3 206 rotate, the cylinder 207 fixedly connected to the bottom of its outer wall also begins to rotate. Multiple striking rods 208 fixedly connected to the outer wall of cylinder 207 rotate accordingly. As the striking rods 208 on multiple cylinders 207 continuously rotate through sleeve 15, they continuously and regularly strike sleeve 15, causing the sample core block inside sleeve 15 to loosen and fall off through vibration.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
