Description

Technical Field

[0001] This utility model relates to a strength testing device for concrete composite thermal insulation blocks, specifically a strength testing device for concrete composite thermal insulation blocks, belonging to the field of concrete composite thermal insulation block testing technology. Background Technology

[0002] Concrete composite insulation blocks are a type of building material composed of multiple materials, possessing thermal insulation properties, high strength, fire resistance, durability, and energy efficiency, making them an indispensable high-efficiency insulation material for modern buildings. They not only improve building energy efficiency but also enhance living comfort and safety, providing strong support for the development of green buildings. During the production of concrete composite insulation blocks, strength testing is necessary to ensure safety during subsequent use.

[0003] A strength testing device for concrete blocks disclosed in Chinese Patent Application Publication CN216208086U features a turntable and threaded holes that facilitate the rotation of a threaded rod. This, in turn, moves a second clamping plate under the sliding limit action of a rotating shaft and a sliding groove. This, in conjunction with the first clamping plate, allows for stable clamping of the concrete block. A limiting rod, passing through a limiting hole and inserted into a limiting groove, further limits the turntable's position and increases the stability of the second clamping plate. A pull plate allows for the stretching of a spring when pulled, enabling the insertion rod to pass through an insertion hole and be inserted into a slot. This facilitates stable installation of the protective cover and ensures high safety.

[0004] However, in the implementation of the above-mentioned patented technical solution, the existing strength testing device uses a hammer to drive an impact block to fall freely onto the concrete composite insulation block, and then observes whether there are cracks or pits on the appearance of the concrete composite insulation block. The existing testing device can only flatten and fix the concrete composite insulation block, and cannot change the fixed angle of the concrete composite insulation block. However, in the actual use of concrete composite insulation blocks, the concrete composite insulation block may be subjected to impacts at any angle, and the horizontally placed concrete composite insulation block cannot accurately obtain the impact effect at the tilt angle, so the strength test is not comprehensive enough.

[0005] Therefore, a strength testing device for concrete composite thermal insulation blocks is proposed here. Utility Model Content

[0006] This invention proposes a strength testing device for concrete composite thermal insulation blocks to solve the problem that existing strength testing devices cannot perform multi-angle impact strength testing on concrete composite thermal insulation blocks.

[0007] This utility model is achieved through the following technical solution: a strength testing device for concrete composite thermal insulation blocks, including a base, an adjustment mechanism is provided above the base, the adjustment mechanism includes a disc, a worm, an upper clamping ring, a lower clamping ring and a semi-worm wheel fixedly connected to the upper surface of the base, the semi-worm wheel meshing with the worm, two arc-shaped sliding frames fixedly connected to the bottom surface of the disc, arc-shaped guide discs slidably connected to the inner walls of the two arc-shaped sliding frames, and both arc-shaped guide discs fixedly connected to the upper surface of the base;

[0008] A fixed base is fixedly connected to the bottom surface of the disc, and a damping disc is fixedly connected to one end of the worm gear near the fixed base. The damping disc is slidably connected to the inner wall of the fixed base, and a bolt is threadedly connected to the inner wall of the fixed base. The bolt is adapted to the damping disc.

[0009] Preferably, the outer surface of the worm is rotatably connected to two support seats, both of which are fixedly connected to the bottom surface of the disk, and the support seats provide support for the rotation of the worm.

[0010] Specifically, the inner wall of the disc is rotatably connected to a bidirectional screw, and the outer surface of the bidirectional screw is threaded with two symmetrical internal thread moving blocks. The upper surfaces of the two internal thread moving blocks are each hinged with two connecting rods, and the top ends of the four connecting rods are all hinged to the bottom surface of the lower clamping ring. The rotation of the bidirectional screw drives the two internal thread moving blocks to move away from or closer to each other. Under the connecting action of the connecting rods, the lower clamping ring is pushed to move up and down.

[0011] Preferably, two guide rods are fixedly connected to the inner wall of the disk. The guide rods pass through the internal thread moving block and are slidably connected to the internal thread moving block. Both guide rods are slidably connected to both internal thread moving blocks, and the guide rods guide the movement of the internal thread moving blocks.

[0012] Furthermore, four fixing rods are fixedly connected to the upper surface of the disc, and the top ends of the four fixing rods are fixedly connected to the outer surface of the upper clamping ring. Four sliding frames are fixedly connected to the outer surface of the lower clamping ring, and the four sliding frames are slidably connected to the outer surfaces of the four fixing rods respectively. The fixing rods and sliding frames guide the movement of the lower clamping ring.

[0013] Preferably, a falling mechanism is provided above the base. The falling mechanism includes a lifting block, a hammer body, and a fixed frame fixedly connected to the upper surface of the base. An electric push rod is fixedly connected to the inner wall of the lifting block. A baffle is fixedly connected to the telescopic end of the electric push rod. The baffle is adapted to the hammer body. An impact block is fixedly connected to the bottom surface of the hammer body. Two symmetrical sliders are fixedly connected to the outer surface of the hammer body. Two symmetrical guide rails are fixedly connected to the inner wall of the fixed frame. The two sliders are slidably connected to the inner walls of the two guide rails respectively. The guide rails and sliders guide the movement of the hammer body.

[0014] The inner wall of the aforementioned fixed frame is rotatably connected to two drive screws. Both drive screws pass through the lifting block and are threadedly connected to the lifting block. The top ends of both drive screws are fixedly connected to sprockets. The two sprockets are connected by chain drive. Under the rotation of the two sprockets and the chain, the two drive screws can rotate.

[0015] This utility model provides a strength testing device for concrete composite thermal insulation blocks, which has the following beneficial effects:

[0016] 1. The strength testing device for this concrete composite thermal insulation block, through the setting of the adjustment mechanism, can adjust the angle of the concrete composite thermal insulation block after it is fixed. Compared with the existing concrete composite thermal insulation blocks that can only be fixed horizontally, it can conduct tests that are closer to the actual use situation, and the test results are more comprehensive, ensuring the accuracy of the test.

[0017] 2. The strength testing device for this concrete composite insulation block uses a falling mechanism. After fixing the concrete composite insulation block, the lifting block is extended, causing the baffle to move below the hammer. The motor on the sprocket is controlled to run, and under the transmission action of the two sprockets and the chain, the two drive screws rotate synchronously, driving the lifting block to move upward. This causes the baffle to push the hammer and impact block upward. After moving to a certain height, the electric push rod is controlled to shorten, causing the baffle to detach from the hammer. The hammer and impact block then fall and impact the concrete composite insulation block, allowing the device to observe whether there are cracks or pits in the concrete composite insulation block.

[0033] Please refer to this carefully. Figure 4 Four fixed rods 216 are fixedly connected to the upper surface of the disc 21.

The four sliding frames 217 are slidably connected to the outer surface of the four fixed rods 216 respectively. The fixed rods 216 and the sliding frames 217 guide the movement of the lower clamping ring 27.

[0034] Please refer to this carefully. Figure 1 and Figure 5A falling mechanism 3 is provided above the base 1. The falling mechanism 3 includes a lifting block 32, a hammer body 37, and a fixed frame 31 fixedly connected to the upper surface of the base 1. An electric push rod 33 is fixedly connected to the inner wall of the lifting block 32. A baffle 34 is fixedly connected to the telescopic end of the electric push rod 33. The baffle 34 is adapted to the hammer body 37. An impact block 38 is fixedly connected to the bottom surface of the hammer body 37. Two symmetrical sliders 310 are fixedly connected to the outer surface of the hammer body 37. Two symmetrical guide rails 39 are fixedly connected to the inner wall of the fixed frame 31. The two sliders 310 are slidably connected to the inner walls of the two guide rails 39 respectively. The guide rails 39 and sliders 310 guide the movement of the hammer body 37.

[0035] Please refer to this carefully. Figure 5 The inner wall of the fixed frame 31 is rotatably connected to two drive screws 35. Both drive screws 35 pass through the lifting block 32 and are threadedly connected to the lifting block 32. The top of each drive screw 35 is fixedly connected to a sprocket 36. The two sprockets 36 are connected by a chain drive. Under the rotation of the two sprockets 36 and the chain, the two drive screws 35 can rotate.

[0036] Working principle: The concrete composite insulation block is placed between the upper clamping ring 26 and the lower clamping ring 27. The bidirectional screw 212 is rotated, which drives the two internal thread moving blocks 213 to move away from each other. The lower clamping ring 27 is pushed upward through the connecting rod 214, so that the concrete composite insulation block is fixed between the upper clamping ring 26 and the lower clamping ring 27. Then, the lifting block 32 is extended, so that the baffle 34 is moved below the hammer body 37. The motor on the sprocket 36 is controlled to run. Under the transmission action of the two sprockets 36 and the chain, the two drive screws 35 are rotated synchronously, which drives the lifting block 32 to move upward. The baffle 34 pushes the hammer body 37 and the impact block 38 to move upward. After moving to a certain height, the electric push rod 33 is controlled to shorten, so that the baffle 34 is separated from the hammer body 37. The hammer body 37 and the impact block 38 fall and impact the concrete composite insulation block.

[0037] Rotating the damping disc 28 causes the worm gear 22 to rotate. Under the meshing action of the worm gear 22 and the semi-worm wheel 23, the angle of the disc 21 changes. At this time, the arc-shaped sliding frame 24 slides on the surface of the arc-shaped guide disc 25. Then, tighten the bolt 210 so that the bolt 210 presses against the damping disc 28. Then, the impact strength test is performed again. By changing the angle multiple times, cracks or pits can be detected in the concrete composite insulation block after being impacted at different angles. This device can fix the concrete composite insulation block and adjust its angle. Compared with the existing concrete composite insulation blocks that can only be fixed horizontally, it can conduct tests that are closer to the actual use situation, and the test results are more comprehensive.
