Description
Technical Field
[0001] This utility model relates to the field of strength testing and detection structure technology, specifically a device for testing the strength of epoxy terrazzo flooring. Background Technology
[0002] In building construction and decoration projects, epoxy terrazzo flooring is widely used in public places, industrial plants, and commercial spaces due to its excellent aesthetics, strength, and wear resistance. However, to ensure its installation quality and service life, on-site testing of the impact resistance of its surface or base layer is often required during project acceptance or subsequent maintenance.
[0003] Existing methods for testing ground impact resistance mainly include: mechanical drop hammer method and electric impact testing device. The mechanical drop hammer method mainly uses the principle of free fall to drive a heavy hammer to fall from different heights to impact the ground, and subjective assessment is made by observing the degree of surface damage; while the electric device uses a motor to drive the movement of the impact head to achieve impact, but it has a complex structure, high cost, and requires a power supply or external control system, making it inconvenient to use outdoors or in conditions without electricity.
[0004] In addition, some existing portable detection devices often provide impact energy by manually pulling a rope or compressing a spring, which generally suffers from the following problems:
[0005] Impact energy is difficult to control: The lack of a precise stroke control mechanism makes it difficult to adjust the impact force, resulting in poor repeatability of test results.
[0006] Poor applicability: Most devices do not consider the adaptability to ground with different strength levels, and the impact head specifications are fixed, which cannot meet the testing needs of multiple scenarios.
[0007] Therefore, existing technologies have significant shortcomings in terms of structural integration, ease of operation, impact energy control accuracy, and on-site adaptability. There is an urgent need for a compact, energy-controllable, highly adaptable, and efficient epoxy terrazzo floor strength testing device to meet the diverse and on-site testing needs of modern building construction for floor material quality control. Utility Model Content
[0008] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0009] Therefore, the technical solution adopted by this utility model is as follows: a testing device for the strength of epoxy terrazzo flooring, including components such as a stand, a punch, a spring winding box, and a pull rope. By utilizing the energy storage and pull-back principle of the spring spring, the punch is driven by the pull rope to complete the impact action on the ground, thereby realizing the rapid testing of the impact resistance of the ground.
[0010] In a preferred embodiment, the device includes a stand, a punch, a spring winding box, and a pull rope. The surface of the stand is provided with a guide groove. The punch is slidably sleeved on the inner side of the stand. The spring winding boxes are symmetrically fixed on both sides of the stand. The two ends of the pull rope are respectively wound inside the two spring winding boxes. The surface of the punch is provided with a sliding wing and a lifting lug. The sliding wing is slidably installed on the inner side of the stand. The lifting lug passes through the guide groove and is slidably installed on the surface of the stand. The spring winding box is provided with a winding box, a winding wheel, and a spring. One end of the spring is connected to the winding wheel to drive its rotation, thereby driving the pull rope to rewind and realize the impact of the punch.
[0011] Specifically, this structure uses a spring-driven mechanism to drive the punch back down, replacing the traditional free-fall or electric drive mechanism, thus avoiding reliance on external power supply and improving field applicability.
[0012] In a preferred embodiment, the reel is rotatably mounted on the side of the support frame and located inside the winding box, which is fixed to the side of the support frame. Specifically, this configuration facilitates a compact overall structure and improves component stability and drive efficiency.
[0013] In a preferred embodiment, the frame is further configured such that: the inner side of the support has a through hole that slides with the punch rod, the through hole is perpendicular to the bottom surface of the support, and the surface of the support has scale lines to indicate the lifting height of the punch rod. Specifically, the impact height can be precisely adjusted through the scale lines, thereby controlling the impact energy and ensuring accurate and reliable test data.
[0014] In a preferred embodiment, the support frame surface is further configured with guide wheels to guide the path of the pull rope. Specifically, the guide wheels prevent the pull rope from interfering with other structures, ensuring smooth retrieval and efficient energy transfer.
[0015] In a preferred embodiment, the top surface of the punch is further configured such that it has an arc-shaped groove for guiding contact with the pull rope. Specifically, this structure improves the stability of the pull rope traction, prevents deflection, and ensures the vertical movement of the punch.
[0016] In a preferred embodiment, the sliding direction of the sliding wing is aligned with the direction of the strike rod, and the sliding wing slides vertically within the support frame. Specifically, this guide structure enhances the stability of the strike rod and effectively prevents deviation.
[0017] In a preferred embodiment, the punch is further configured such that a tapered tungsten carbide punch is detachably mounted at the bottom end of the punch rod. The punch can be replaced with different specifications according to testing requirements. Specifically, different punches correspond to different impact pressures, making them suitable for ground materials of different strength grades, thus improving the versatility and adaptability of the test.
[0018] With the above structural configuration, this utility model is not only simple in structure and easy to operate, but also has good impact force control capability, strong adaptability and high testing efficiency. It is particularly suitable for rapid strength assessment and quality judgment of epoxy terrazzo flooring in construction sites, project acceptance and other scenarios.
[0019] The beneficial effects achieved by this utility model are as follows:
[0020] 1. In this utility model, the spring spring inside the spring winding box drives the pull rope to automatically rewind, thereby realizing the automatic falling impact of the punch. It has a compact structure, is easy to operate, avoids dependence on external power supply or complex drive mechanism, and is suitable for on-site rapid testing scenarios.
[0021] 2. In this utility model, by setting scale lines on the surface of the upright frame and using the sliding guide groove, sliding wing and lifting lug to guide and position the movement path of the punch rod, the impact height and force can be precisely controlled. Combined with punches of different specifications, it can be adapted to the testing needs of epoxy terrazzo floors of various strength levels, thereby improving the accuracy and applicability of the test.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0029] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.
[0030] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a testing device for the strength of epoxy terrazzo flooring.
[0031] Combination Figures 1-4 As shown, the present invention provides a testing device for the strength of epoxy terrazzo flooring, comprising a frame 100, a punch 200, a spring winding box 300, and a pull rope 400.
[0032] The surface of the support frame 100 is provided with a sliding guide groove 110, and the punch 200 is slidably sleeved on the inner side of the support frame 100. The spring winding box 300 is fixedly installed on both sides of the support frame 100, and the two ends of the pull rope 400 are respectively wound and arranged on the inner side of the two spring winding boxes 300, so that the pull rope 400 can be synchronously wound back on both sides under the drive of the spring winding box 300.
[0033] The outer surface of the punch rod 200 is fixedly equipped with a sliding wing 210 and a lifting lug 220. The sliding wing 210 is slidably installed on the inner side of the upright 100 to limit and guide the vertical movement of the punch rod 200. The lifting lug 220 passes through the sliding guide groove 110 and is slidably installed on the surface of the upright 100 to operate and limit the punch rod 200.
[0034] The spring cassette 300 includes a take-up cassette 310, a winding wheel 320, and a spring cassette 330. The take-up cassette 310 is fixedly installed on the side of the support frame 100. The winding wheel 320 is disposed inside the take-up cassette 310 and rotatably installed on the side of the support frame 100. The spring cassette 330 is fixed inside the take-up cassette 310, and one end of it is connected to the surface of the winding wheel 320 to drive the winding wheel 320 to rotate, thereby driving the pull rope 400 to rewind.
[0035] Furthermore, the inner side of the support frame 100 is provided with a through hole for the punch rod 200 to slide through, and the through hole is set perpendicular to the bottom surface of the support frame 100. The surface of the support frame 100 is provided with scale lines to guide the sliding wing 210 to slide vertically and to indicate the current height position of the punch rod 200.
[0036] Preferably, the surface of the support frame 100 is also provided with guide wheels to guide the path of the pull rope 400 so as to avoid interference between the pull rope 400 and other components.
[0037] The top surface of the punch 200 is provided with a groove, which has an arc-shaped structure and is used to contact the surface of the pull rope 400 and guide its force direction, thereby improving the force transmission efficiency and the stability of the movement of the punch 200.
[0038] like Figure 2 As shown, the sliding wing 210 slides vertically along the inner wall of the support frame 100, and the sliding direction is parallel to the axial direction of the punch 200, thereby ensuring that the punch 200 does not deviate under stress.
[0039] like Figure 4 As shown, a punch head is detachably installed at the bottom of the punch rod 200. The punch head is made of tungsten steel and has a conical structure. Different impact pressures can be achieved by replacing the punch head with different specifications. It is suitable for strength testing of epoxy terrazzo flooring of different strength grades.
[0040] During operation, the operator pulls the rope 400, causing the impact rod 200 to slide upwards, during which the spring clockwork 330 is stretched and stores energy. The impact energy can be controlled by reading the height pulled, as indicated by a scale. Releasing the rope 400 causes the spring clockwork 330 to drive the reel 320 to rotate, rapidly rewinding the rope 400 and causing the impact rod 200 to move downwards. The impact head at the bottom strikes the ground, completing the impact test. Different pulling heights correspond to different impact forces. By observing the crack morphology and damage extent of the ground after impact, the impact resistance level of the ground can be determined.
[0041] Working principle and usage process of this utility model:
[0042] This invention utilizes a spring 330 within the spring winding box 300 to provide elastic rotational force, driving the pull rope 400 to rewind, thereby causing the punch 200 to slide within the stand 100, achieving the impact strike of the punch on the epoxy terrazzo floor. Its working process is as follows:
[0043] Spring-driven energy storage: The two ends of the pull rope 400 are respectively wound and arranged in two spring winding boxes 300. The spring winding box 300 includes a winding box 310, a winding wheel 320 and a spring spring 330 connected to the winding wheel 320. When the pull rope 400 is pulled out, the spring spring 330 is forced to stretch and store energy.
[0044] Pull rope rewinding traction impact: After the pull rope 400 is released, the spring clock 330 drives the winding wheel 320 to rotate, causing the pull rope 400 to rewind quickly and the traction impact rod 200 to move downward.
[0045] Punch rod guidance and stabilization: The punch rod 200 is slidably sleeved inside the upright 100 and is stably guided by the sliding wing 210 and the lifting lug 220. The sliding wing 210 is slidably installed inside the upright 100, and the lifting lug 220 passes through the guide groove 110 and is slidably installed on the surface of the upright 100 to guide and limit the movement path of the punch rod 200.
[0046] Impact test: A punch is detachably mounted on the bottom of the punch rod 200. The punch is made of tungsten steel and has a conical structure. Driven by the pull rope 400, the punch rod 200 falls at high speed, and the punch hits the ground to complete the impact test.
[0047] The impact rod 200 is pulled upwards and slides along the guide groove 110. Its sliding path is limited and guided by the sliding wing 210 and the lifting lug 220, ensuring that the impact rod 200 maintains stable vertical movement inside the stand 100. The surface of the stand 100 is provided with scale lines to indicate the lifting height and to visually display the current position of the impact rod 200. The lifting height of the impact rod 200 can be adjusted by controlling the length of the pull rope 400. The higher the lifting height, the greater the energy stored in the spring clock 330, and the greater the kinetic energy generated by the impact rod 200 upon release, i.e., the stronger the impact force. By adjusting the impact force at different lifting heights, the damage effect of epoxy terrazzo flooring under different impact loads can be evaluated. Furthermore, based on the cracking, fragmentation, or deformation of the floor, its impact resistance can be determined, achieving a rapid and graded floor strength testing effect.
