Description

Technical Field

[0001] This utility model relates to the field of bridge construction testing technology, specifically a concrete compressive strength testing device for bridge construction. Background Technology

[0002] Concrete is the most widely used and most important structural material in modern civil engineering. Its most important mechanical property is compressive strength, that is, its ability to resist compressive stress. This property directly determines the safety, durability, and stability of structures such as houses, bridges, dams, and roads. Compressive strength testing is the only legally mandated means to directly and quantitatively verify whether on-site poured concrete has reached its design strength grade. Without test data, it is impossible to prove that a project meets design requirements, representing a significant deficiency in quality control. Concrete compressive strength testing is far more than a simple "experiment"; it is a quality bridge connecting the three major stages of design, construction, and acceptance, and a core guarantee system for ensuring the safe, compliant, economical, and efficient operation of building projects. Its necessity is rooted in every aspect of modern engineering management and is an unshakable quality cornerstone in this technical field.

[0003] During compressive strength testing, conventional testing equipment can only manually feed the concrete or directly test the corresponding location. Testing personnel need to manually unload the concrete test blocks. For concrete with large mass compressive strength, testing personnel need to unload the blocks multiple times. This undoubtedly causes inconvenience in current concrete compressive strength testing. Therefore, a concrete compressive strength testing device for bridge construction with automatic unloading and easy-to-push feeding is designed to solve the above problems. Utility Model Content

This solves the problem that general testing equipment can only be manually fed or directly tested at the corresponding location, requiring testing personnel to manually feed the concrete test blocks. For concrete with large mass compressive strength, testing personnel need to feed the blocks multiple times, which undoubtedly causes inconvenience in the current concrete compressive strength testing.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned goals of automatic material feeding and easy material loading, this utility model provides the following technical solution: a concrete compressive strength testing device for bridge construction, comprising a support frame and a support leg disposed on the lower side of the support frame, and an mounting frame mounted on the upper side of the support frame, the upper end of the mounting frame being provided with a mounting plate, one end of the mounting plate being rotatably connected to the inner wall of the mounting frame, a testing hydraulic cylinder being disposed inside the mounting plate, a positioning frame being disposed at the output end of the testing hydraulic cylinder, and a pressure sensor being disposed inside the positioning frame, a pushing frame being disposed inside the support frame, and a concrete block being disposed on one side of the pushing frame.

[0008] Preferably, the outer side of the detection hydraulic cylinder is provided with a fixing block, and the inside of the fixing block is provided with a limiting rod. One end of the limiting rod passes through the inside of the mounting plate, and the positioning frame is fixedly installed at the lower end of the limiting rod. The pressure sensor is located at the output end of the detection hydraulic cylinder.

[0009] Preferably, the support frame has a base inside, and the base is located below the positioning frame. One end of the base is provided with an electric push rod, and the push frame is installed at the output end of the electric push rod. The concrete block is located inside the base.

[0010] Preferably, the pusher frame has rotatably connected connectors at both ends, and one end of the connector has a rotatably connected pusher. One end of the pusher is equipped with a rotating component, which is installed on the inner wall of the base. The lower side of the rotating component is rotatably connected to the interior of the base, and one side of the rotating component is in contact with one side of the concrete block.

[0011] Preferably, the base has a limiting block inside, and one end of the limiting block is rotatably connected to the inner wall of the base. The base has a limiting spring inside, and both ends of the limiting spring are fixedly connected to one end of the limiting block and the inner wall of the base, respectively. The limiting block is located at one end of the concrete block.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a concrete compressive strength testing device for bridge construction, which has the following beneficial effects: This concrete compressive strength testing device for bridge construction involves placing a concrete block through one end of a support frame concrete block into the interior of the support frame concrete block, so that one end of the support frame concrete block contacts the pushing frame concrete block. The positioning frame concrete block positions the concrete, and then the detection hydraulic cylinder moves the concrete block vertically, driving the pressure sensor to press the concrete block. The pressure sensor measures the pressure borne by the concrete block. When the test is completed, the pushing frame concrete block pushes the concrete block out of the interior of the support frame concrete block, thereby achieving the effects of automatic material feeding and convenient pushing and loading.

[0019] 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.

[0020] Example: Please refer to Figure 1-4 A concrete compressive strength testing device for bridge construction includes a support frame 1 and support legs 2 located on the lower side of the support frame 1. An mounting frame 3 is installed on the upper side of the support frame 1, and a mounting plate 4 is provided at the upper end of the mounting frame 3. One end of the mounting plate 4 is rotatably connected to the inner wall of the mounting frame 3. A testing hydraulic cylinder 6 is located inside the mounting plate 4, and a positioning frame 5 is provided at the output end of the testing hydraulic cylinder 6. A pressure sensor 15 is located inside the positioning frame 5. A pusher frame 9 is located inside the support frame 1, and a concrete block is placed on one side of the pusher frame 9. The concrete block is placed into the support frame 1 through one end, so that one end contacts the pusher frame 9. The positioning frame 5 positions the concrete. The testing hydraulic cylinder 6 moves vertically, driving the pressure sensor 15 to press the concrete block. The pressure sensor 15 measures the pressure borne by the concrete block. When the test is completed, the concrete block is pushed out of the support frame 1 through the pusher frame 9.

[0021] A fixing block 16 is provided on the outside of the detection hydraulic cylinder 6, and a limiting rod 17 is provided inside the fixing block 16. One end of the limiting rod 17 passes through the interior of the mounting plate 4, and the positioning frame 5 is fixedly installed at the lower end of the limiting rod 17. The pressure sensor 15 is located at the output end of the detection hydraulic cylinder 6. After the concrete block is placed, the positioning frame 5 moves vertically through the limiting rod 17 and the fixing block 16 to position the concrete block, thus determining its position and facilitating position judgment, thereby reducing detection errors.

[0022] The support frame 1 has a base 7 inside, which is located below the positioning frame 5. One end of the base 7 is equipped with an electric push rod 8, and a push frame 9 is installed at the output end of the electric push rod 8. The concrete block is placed inside the base 7. When the inspection is completed, the electric push rod 8 pushes the concrete block horizontally through the push frame 9 to change its inspection position. When all inspections are completed, the electric push rod 8 drives the push frame 9 to push the concrete block out, thus facilitating its unloading.

[0023] The pusher frame 9 has rotatably connected connectors 10 at both ends, and a rotatably connected pusher 11 at one end of each connector 10. A rotating component 12 is mounted on one end of each pusher 11, and the rotating component 12 is mounted on the inner wall of the base 7. The lower side of the rotating component 12 is rotatably connected to the interior of the base 7, and one side of the rotating component 12 contacts one side of the concrete block. The pusher frame 9 connects the two rotating components 12 through the connectors 10 at both ends and the corresponding pusher 11, allowing the rotating components 12 to push the concrete block. The rotating component 12 drives the pusher frame 9 to move horizontally via the electric push rod 8, causing it to pull the corresponding rotatably connected connectors through the connectors 10 and the pusher 11, causing it to rotate. During the rotation, it pushes the concrete block. When the limit is reached, the pusher frame 9 contacts the concrete and pushes it out.

[0024] The base 7 has a limiting block 13 inside, and one end of the limiting block 13 is rotatably connected to the inner wall of the base 7. The base 7 also has a limiting spring 14 inside, and both ends of the limiting spring 14 are fixedly connected to one end of the limiting block 13 and the inner wall of the base 7, respectively. The limiting block 13 is located at one end of the concrete block. The function of the limiting block 13 is to limit the position of the concrete block. One side of the limiting block 13 has a slope, which reduces the friction of the concrete block. This allows the limiting block to not only limit its position but also to be pushed out by the pusher 9. The limiting spring 14 supports the limiting block 13, and the weight of the concrete block itself is sufficient to compress the limiting spring 14.

[0025] Working principle: The concrete block is placed into the support frame 1 through one end, so that one end contacts the pusher frame 9. After the concrete block is placed, the positioning frame 5 moves vertically through the limit rod 17 and the fixing block 16 to position the concrete block, so that the position of the concrete block is determined, which makes it easier to judge the position and reduce the detection error. The detection hydraulic cylinder 6 moves vertically to drive the pressure sensor 15 to press the concrete block. The pressure sensor 15 measures the pressure on the concrete block. When the detection is completed, the concrete block is pushed out of the support frame 1 through the pusher frame 9. When the detection is completed, the electric push rod 8 pushes the concrete block horizontally through the pusher frame 9 to change the detection position. When all the detection is completed, the electric push rod 8 drives the pusher frame 9 to push the concrete block out, which makes it easier to unload the material.
