Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering testing technology, and in particular to a concrete strength testing device. Background Technology
[0002] Concrete strength is a core indicator of building structural safety, and its test results directly affect project quality assessment, structural maintenance, and lifespan prediction. Core drilling, because it can directly obtain concrete core samples and obtain true strength values through compressive strength tests, has become one of the most intuitive and reliable testing methods recognized in the industry.
[0003] Traditional core drilling equipment mainly consists of a drive system, a drilling system, a fixing system, and a cooling system. The drive system is powered by an electric motor or gasoline engine, which drives the drill bit to rotate via a transmission. The drilling mechanism is controlled manually or hydraulically for feeding. The fixing device is a tripod or a suction cup. The cooling system uses a water pump to cool the drill bit.
[0004] Currently, the fixing devices of traditional equipment have poor adaptability to curved or inclined surfaces, which can easily cause the equipment to shift or tip over, affecting the quality of the core sample. At the same time, when the motor of traditional equipment runs for a long time, it continuously consumes energy and generates heat. The heat accumulation causes the shell temperature to rise. If heat dissipation is not timely, it can easily lead to insulation aging, or even cause performance degradation or burnout. Utility Model Content

As a further description of the above technical solution: The adaptive fixing component includes a fixing base, a suction cup connecting rod rotatably connected to the outer periphery of the fixing base, a rotating joint rotatably connected to one side of the suction cup connecting rod, and a vacuum suction cup threaded to the bottom of the rotating joint.

[0007] This utility model has the following beneficial effects: 1.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0011] Reference Figures 1-5 This utility model provides an embodiment of a concrete strength testing device, comprising a main frame 1, a drive motor 2 fixedly connected to one side of the main frame 1, a heat-conducting pipe 3 abutting against the outer wall of the drive motor 2, and the heat-conducting pipe 3 being attached to the outer wall of the drive motor 2 to conduct heat generated during the operation of the drive motor 2. A heat sink 4 is fixedly connected to the outer side of the heat-conducting pipe 3, and a cooling shell 5 is threadedly connected to the outer side of the drive motor 2. A cooling fan 6 is fixedly connected to the inner wall of the cooling shell 5, and ventilation holes are provided on the outer periphery of the cooling shell 5. The cooling fan 6 inside the cooling shell 5, in conjunction with the ventilation holes on the outer periphery, forms an air circulation channel, accelerating airflow and carrying away the heat dissipated by the heat sink 4 and the drive motor 2, creating a good cooling environment for the drive motor 2. A sampling component 7 is provided at the drive end of the drive motor 2, the sampling component 7 including a protective shell 22, and a gearbox 23 threadedly connected to the inner wall of the protective shell 22. The gearbox 23 can change the speed and torque transmitted from the drive motor 2. A drill bit 24 is threadedly connected to one side of the gearbox 23, and a drill barrel 25 is threadedly connected to the top of the drill bit 24. A cutting edge is provided on the top of the drill barrel 25. The drill barrel 25 rotates together with the drill bit 24, and the cutting edge on its top assists the drill bit 24 in cutting concrete.
[0012] Reference Figure 1 , Figure 2 and Figure 6 A feed mechanism 8 is fixedly connected to one side of the main frame 1. The feed mechanism 8 includes a protective shell 16, and a feed motor 17 is fixedly connected inside the protective shell 16. A transmission gear 18 is fixedly connected to the drive end of the feed motor 17. The feed motor 17 provides power to the feed mechanism 8, driving the transmission gear 18 to rotate. A feed gear 19 is meshed with the outer side of the transmission gear 18. A rotary bearing 20 is fixedly connected to one side of the feed gear 19. The outer wall of the rotary bearing 20 is fixedly connected to the bottom of the feed gear 19, and the inner wall of the rotary bearing 20 is fixedly connected to the inside of the main frame 1. By installing the rotary bearing 20 between the bottom of the feed gear 19 and the inside of the main frame 1, the friction between the feed gear 19 and the main frame 1 is reduced when the feed gear 19 rotates, allowing the feed gear 19 to rotate more smoothly. The inner wall of the feed gear 19 is threadedly connected to a threaded guide rail 21. Through the interaction between the inner wall of the feed gear 19 and the threaded guide rail 21, the rotation of the feed gear 19 is converted into linear motion along the threaded guide rail 21, driving related components to achieve the feeding or retraction of the sampling assembly 7. The bottom of the threaded guide rail 21 is threadedly connected to the top of the fixed base 10. The bottom of the feed mechanism 8 is threadedly connected to an adaptive fixing assembly 9. The adaptive fixing assembly 9 includes the fixed base 10, with a suction cup connecting rod 11 rotatably connected to the outer periphery of the fixed base 10. A rotating joint 12 is rotatably connected to one side of the suction cup connecting rod 11, and a vacuum suction cup 13 is threadedly connected to the bottom of the rotating joint 12. Through the vacuum suction cup 13 and the suction cup connecting rod 11, the device adapts to different surface conditions, ensuring that it does not shift or shake during core drilling, thus ensuring smooth operation of the testing work. A bolt fixing groove 14 is provided on one side of the fixed base 10, and a vacuum pump 15 is threadedly connected to one side of the fixed base 10. The bolt fixing groove 14 can be used with bolts. When the vacuum suction cup 13 is not effective enough or in some special cases, the fixed base 10 can be fixed to the concrete surface with bolts to enhance the overall fixing strength of the device.
[0013] Working principle: After the device is started, the drive motor 2, as the core power source, converts electrical energy into mechanical energy. The heat generated is conducted to the heat sink 4 through the heat pipe 3 for dissipation. At the same time, the cooling fan 6 inside the cooling shell 5 accelerates air circulation, forming a heat dissipation channel through the ventilation holes, ensuring the stable operation of the drive motor 2. The power from the motor drive end is transmitted to the drill bit 24 and drill barrel 25 after the speed and torque are adjusted by the gearbox 23 in the sampling component 7, causing them to rotate at high speed to cut the concrete.
[0014] During the core drilling process, the feed mechanism 8 works in coordination, and the feed motor 17 drives the transmission gear 18 to rotate. Through the meshing transmission with the feed gear 19, combined with the support of the rotating bearing 20, the feed gear 19 moves linearly along the threaded guide rail 21, accurately controlling the feed depth and speed of the sampling component 7, ensuring that the drilled core sample is complete and meets the testing requirements.
[0015] 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.
