Description

A building material strength testing device Technical Field

[0001] This utility model relates to the field of building material testing technology, and in particular to a building material strength testing device. Background Technology

[0002] Building materials are the various materials used in construction projects. There are many types of building materials, which can be roughly divided into: inorganic materials, including metallic and non-metallic materials; organic materials, including plant-based materials, synthetic polymer materials, and asphalt materials; and composite materials, including asphalt concrete, polymer concrete, etc., which are generally composed of inorganic non-metallic materials and organic materials. Before their use, they often need to undergo corresponding strength tests to ensure their safety during use.

[0003] Chinese utility model patent CN220912863U discloses a building material strength testing device, including a base plate. A clamping mechanism is provided on the upper surface of the base plate. The clamping mechanism includes a bidirectional threaded rod, a motor, a threaded block, and a first fixing plate. A rectangular groove is formed on the upper surface of the base plate. This building material strength testing device, through the rectangular groove on the upper surface of the base plate, allows the bidirectional threaded rod to be installed inside the groove. After installation, the motor, fixedly mounted on the right side of the base plate, provides power, enabling the bidirectional threaded rod, which is fixedly connected to the motor's output shaft, to rotate. When the bidirectional threaded rod rotates, it effectively solves the problem of how to adapt to the strength testing of building materials of different sizes, achieving a convenient testing effect. At the same time, it improves the practical applicability of the device, enabling it to be used in different situations and improving its practical effectiveness.

[0004] Existing building material strength testing devices may experience broken samples falling onto the base when the material is subjected to significant pressure and approaches its ultimate strength. If a broken sample falls onto the base and enters the area where the bidirectional threaded rod is located, it may cause the bidirectional threaded rod to jam. Jamming of the bidirectional threaded rod will prevent the device from performing clamping and testing operations normally, which will not only affect the testing efficiency but may also damage related components of the device, increasing maintenance costs and time. Therefore, there is a problem that it is not easy to protect the clamping components. Summary of the Invention

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Example 1

[0033] Referring to Figures 1, 2, 3, and 4, this is the first embodiment of the present invention. This embodiment provides a building material strength testing device, including a base 1. A protective mechanism 2 is fixedly connected to the outer surface of the base 1, and an adjustment mechanism 3 is fixedly connected to the outer surface of the protective mechanism 2. The protective mechanism 2 includes a protective frame 202 and a support frame 209 fixedly connected to the upper surface of the base 1. A fixed frame 206 is fixedly connected to the upper surface of the support frame 209. Two sets of baffles 207 are slidably connected to the inner wall of the fixed frame 206. Sliding frames 205 are fixedly connected to the outer surface of each baffle 207, and a door panel 201 is hinged to the inner side of the protective frame 202.

[0034] Specifically, a rack rod 211 is fixedly connected to the outer surface of the sliding frame 205, and a gear 212 is meshed with the outer surface of the rack rod 211. The outer surface of the gear 212 is rotatably connected to the inner wall of the support frame 209. A first reduction motor 208 is fixedly connected to the outer surface of the support frame 209, and the output shaft of the first reduction motor 208 is fixedly connected to the outer surface of the gear 212. A limiting groove 210 is provided on the inner wall of the support frame 209, and the outer surface of the rack rod 211 is slidably connected to the outer surface of the limiting groove 210. A first electric telescopic rod 204 is fixedly connected to the inner wall of the sliding frame 205, and a clamping plate 203 is fixedly connected to the output end of the first electric telescopic rod 204. A heat dissipation hole is provided on the outer surface of the sliding frame 205. A limiting block 213 is fixedly connected to the outer surface of the baffle 207, and the outer surface of the limiting block 213 is slidably connected to the inner wall of the fixed frame 206.

[0035] The first reduction motor 208 is then activated. The output shaft of the first reduction motor 208 drives the gear 212 to rotate. The rotation of the gear 212 drives the two sets of rack rods 211 to move in opposite directions, thereby facilitating the adjustment of the spacing of the sliding frame 205 and making it easier to clamp samples of different lengths. Then, the first electric telescopic rod 204 is activated. The output end of the first electric telescopic rod 204 drives the clamping plate 203 to move downward, making it easier to clamp samples of different thicknesses. When the sliding frame 205 slides on the upper surface of the base 1, the sliding frame 205 drives the baffle 207 to slide on the inner wall of the fixed frame 206, thereby allowing the fixed frame 206 to block the upper surface of the rack rods 211, thus preventing broken samples from hindering the sliding frame 205 from sliding on the upper surface of the base 1.

[0036] Example 2

[0037] Referring to Figures 1, 2, 3, and 4, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The adjustment mechanism 3 includes an adjustment housing 308 fixedly connected to the outer surface of the protective frame 202. A sliding plate 301 is slidably connected to the outer surface of the adjustment housing 308. A second electric telescopic rod 303 is fixedly connected to the outer surface of the sliding plate 301. A connecting plate 306 is fixedly connected to the output end of the second electric telescopic rod 303. A hydraulic telescopic rod 305 is fixedly connected to the outer surface of the connecting plate 306. A pressure detector 307 is fixedly connected to the output end of the hydraulic telescopic rod 305.

[0038] Specifically, the outer surface of the slide plate 301 is slidably connected to a limit rod 302, the outer surface of the limit rod 302 is fixedly connected to the outer surface of the connecting plate 306, the outer surface of the adjusting housing 308 is fixedly connected to a second reduction motor 304, the output shaft of the second reduction motor 304 is fixedly connected to a threaded rod 309, and the outer surface of the threaded rod 309 is threadedly connected to the outer surface of the slide plate 301.

[0039] The second reduction motor 304 is then activated. The output shaft of the second reduction motor 304 drives the threaded rod 309 to rotate. The rotation of the threaded rod 309 causes the sliding plate 301 to slide on the upper surface of the adjusting housing 308, facilitating the adjustment of the position of the pressure detector 307. Then, the second electric telescopic rod 303 is activated. The output end of the second electric telescopic rod 303 drives the connecting plate 306 to slide along the direction of the limiting rod 302, allowing the pressure detector 307 to perform detection at different positions on the sample. After the position of the pressure detector 307 is adjusted, the hydraulic telescopic rod 305 is activated. The output end of the hydraulic telescopic rod 305 drives the pressure detector 307 to move downward, facilitating the detection of the sample.

[0040] Working principle: By opening the door panel 201, the first reduction motor 208 is started. The output shaft of the first reduction motor 208 drives the gear 212 to rotate. The rotation of the gear 212 drives the two sets of racks 211 to move in opposite directions, thereby facilitating the adjustment of the spacing of the sliding frame 205 and making it easier to clamp samples of different lengths. Then, the first electric telescopic rod 204 is started. The output end of the first electric telescopic rod 204 drives the clamping plate 203 to move downward, facilitating the clamping of samples of different thicknesses. When the sliding frame 205 slides on the upper surface of the base 1, the sliding frame 205 drives the baffle 207 to slide on the inner wall of the fixed frame 206, thereby allowing the fixed frame 206 to shield the upper surface of the racks 211, thus preventing broken samples from obstructing the sliding frame 205 at the bottom. When the upper surface of seat 1 slides, the protective frame 202 and door panel 201 facilitate the protection of the staff. By starting the second reduction motor 304, the output shaft of the second reduction motor 304 drives the threaded rod 309 to rotate. The rotation of the threaded rod 309 causes the sliding plate 301 to slide on the upper surface of the adjusting housing 308, which facilitates the adjustment of the position of the pressure detector 307. Then, the second electric telescopic rod 303 is started. The output end of the second electric telescopic rod 303 drives the connecting plate 306 to slide along the direction of the limiting rod 302, so that the pressure detector 307 can detect at different positions of the sample. After the position of the pressure detector 307 is adjusted, the hydraulic telescopic rod 305 is started. The output end of the hydraulic telescopic rod 305 drives the pressure detector 307 to move downward, which facilitates the detection of the sample.
