Technical Field

[0001] This utility model belongs to the technical field of concrete compressive strength data acquisition and testing device, and particularly relates to a concrete compressive strength data acquisition and testing device. Background Technology

[0002] Concrete is an artificial stone material made by mixing cementitious materials, aggregates, water, and other admixtures in a certain proportion, followed by stirring, molding, and curing. It features high strength, good durability, and abundant raw materials. The compressive strength of concrete is one of its most important performance indicators. By testing the compressive strength data, it can be determined whether the concrete has reached the design strength grade, thereby ensuring the safety and reliability of buildings or structures. In summary, the existing technology has the following problems: Concrete testing machines are devices used to test the performance of concrete. During use, concrete specimens need to be placed on the test platform, and then the machine body compresses the concrete specimens. To prevent uneven stress on the concrete specimens and the resulting measurement errors, the concrete specimens need to be positioned. Typically, concrete testing machines use bolts to adjust the position of the clamping parts for positioning. During use, due to factors such as vibration, the bolts may gradually loosen, causing changes in the position of the clamping parts and affecting their stability. Furthermore, the bolt operation process is relatively complex. However, existing concrete testing machines lack a more convenient and stable component for positioning concrete specimens. Therefore, a concrete compressive strength data acquisition and testing device is proposed to solve the above problems. Utility Model Content

[0003] To address the problems of existing technologies, this utility model provides a concrete compressive strength data acquisition and testing device. This device offers the advantage of enabling concrete testing machines to more conveniently and stably position concrete specimens. It solves the problem that existing concrete testing machines, used for testing concrete performance, require placing the concrete specimen on a test platform and then compressing it to obtain test data. To prevent measurement errors caused by uneven stress on the concrete specimen, positioning is necessary. Typically, concrete testing machines use bolts to adjust the position of the clamping components. However, during use, the bolts may gradually loosen due to vibration, external forces, etc., causing changes in the clamping component's position and affecting its stability. Furthermore, the bolt operation is relatively complex. Existing concrete testing machines lack a component for more convenient and stable positioning of concrete specimens.

[0004] This utility model is implemented as follows: a concrete compressive strength data acquisition and testing device includes a concrete testing machine and a testing platform. The testing platform is set in the inner cavity of the concrete testing machine. Four positioning clasps are fixedly connected to the bottom of the testing platform. The inner cavity of each positioning clasp is provided with a positioning device.

[0005] As a preferred embodiment of this utility model, the positioning device includes a double positioning block. The top of the double positioning block penetrates through the positioning housing and extends to the outside of the inner cavity of the positioning housing. Two locking holes are formed on the surface of the double positioning block. A spring is fixedly connected to the surface of the double positioning block. The surface of the spring is fixedly connected to the inner cavity of the positioning housing. By setting the positioning device, when the clamping disc moves to a position that contacts the surface of the concrete specimen, the positioning device has a limiting effect on the position of the clamping disc.

[0006] As a preferred embodiment of this utility model, the inner cavity of the positioning card case is fixedly connected to two card hole plates that cooperate with the card holes. The surfaces of the card holes and the card hole plates are movably connected. By setting the card hole plates, when the positioning double card blocks move, the card holes will move along the surface of the card hole plates. The cooperation between the card holes and the card hole plates has a limiting effect on the movement position of the positioning double card blocks.

[0007] In a preferred embodiment of this invention, a mating cylinder is fixedly connected to the surface of the positioning double-block, and a mating rotating ring that mates with the mating cylinder is movably connected to the inner cavity of the positioning housing via a rotating shaft. The inner cavity of the mating rotating ring is movably connected to the surface of the mating cylinder, and the side of the mating rotating ring away from the test bench penetrates the positioning housing and extends to the outer side of the inner cavity of the positioning housing. By setting the mating cylinder and the mating rotating ring, when the mating rotating ring rotates, it can generate a compressive force on the mating cylinder, and the mating cylinder subjected to the compressive force can drive the positioning double-block to move.

[0008] As a preferred embodiment of this utility model, a positioning frame is movably connected to the surface of the positioning housing on the side away from the positioning double block. By setting the positioning frame, the clamping disk can be moved when the positioning frame moves. The cooperation between the positioning frame and the positioning housing has a limiting effect on the movement position of the clamping disk.

[0009] As a preferred embodiment of this utility model, the surface of the positioning card frame is fixedly connected with a clamping plate. By setting the clamping plate, when the surfaces of all four clamping plates are in contact with the surface of the concrete specimen, the position of the concrete specimen will be restricted.

[0010] As a preferred embodiment of this utility model, the bottom of the positioning card frame is provided with several card slots that cooperate with the positioning double card blocks. The surface of the positioning double card blocks contacts the inner cavity of the card slots. By setting the card slots, when the clamping plate moves to the appropriate position, the cooperating ring is released, and the restoring force generated by the spring returning to its shape will drive the positioning double card blocks to be inserted into the inner cavity of the card slots. The cooperation between the positioning double card blocks and the card slots has a limiting effect on the position of the clamping plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model solves the problem of existing concrete testing machines, which are devices used to test the performance of concrete. During use, concrete specimens need to be placed on the test platform, and then the machine body squeezes the concrete specimens. In order to prevent measurement errors caused by uneven force on the concrete specimens, the concrete specimens need to be positioned. Usually, concrete testing machines use bolts to adjust the position of the clamping parts to position the concrete specimens. During use, the bolts may gradually loosen due to factors such as vibration, causing the position of the clamping parts to change and affecting the stability of the clamping parts. Moreover, the operation of the bolts is relatively complicated. However, existing concrete testing machines do not have a more convenient and stable component for positioning concrete specimens.

[0013] 2. This utility model, by setting a positioning device, will cause the card hole to move along the surface of the card hole plate when the positioning double card block moves. At the same time, the force generated when the positioning double card block moves will cause the spring to undergo elastic deformation. The restoring force generated by the spring returning to its shape will cause the positioning double card block to be locked into the inner cavity of the card block groove. The positioning device has a limiting effect on the position of the clamping plate. Attached Figure Description

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4As shown in the figure, the concrete compressive strength data acquisition and testing device provided in this embodiment of the utility model includes a concrete testing machine 1 and a test bench 2. The test bench 2 is set in the inner cavity of the concrete testing machine 1. Four positioning clips 3 are fixedly connected to the bottom of the test bench 2. The inner cavity of the positioning clips 3 is provided with positioning devices 4.

[0022] refer to Figure 4 The positioning device 4 includes a positioning double block 401. The top of the positioning double block 401 passes through the positioning housing 3 and extends to the outside of the inner cavity of the positioning housing 3. Two locking holes 402 are opened on the surface of the positioning double block 401. A spring 403 is fixedly connected to the surface of the positioning double block 401. The surface of the spring 403 is fixedly connected to the inner cavity of the positioning housing 3.

[0023] The above scheme is adopted: by setting the positioning device 4, when the clamping plate 9 moves to the position that contacts the surface of the concrete specimen, the positioning device 4 has a limiting effect on the position of the clamping plate 9.

[0024] refer to Figure 4 The inner cavity of the positioning clasp 3 is fixedly connected to two clasp plates 5 that cooperate with the clasp holes 402, and the surfaces of the clasp holes 402 and the clasp plates 5 are movably connected.

[0025] The above solution is adopted: by setting the card hole plate 5, when the positioning double card block 401 moves, it will drive the card hole 402 to move along the surface of the card hole plate 5. The cooperation between the card hole 402 and the card hole plate 5 has a limiting effect on the movement position of the positioning double card block 401.

[0026] refer to Figure 4 The surface of the positioning double block 401 is fixedly connected to a mating cylinder 6. The inner cavity of the positioning clasp 3 is movably connected to a mating rotating ring 7 that mates with the mating cylinder 6 via a rotating shaft. The inner cavity of the mating rotating ring 7 is movably connected to the surface of the mating cylinder 6. The side of the mating rotating ring 7 away from the test bench 2 passes through the positioning clasp 3 and extends to the outer side of the inner cavity of the positioning clasp 3.

[0027] The above scheme is adopted: by setting a mating cylinder 6 and a mating rotating ring 7, when the mating rotating ring 7 rotates, it can generate a squeezing force on the mating cylinder 6. The mating cylinder 6 subjected to the squeezing force can drive the positioning double locking block 401 to move.

[0028] refer to Figure 3 The positioning card holder 3 has a positioning card frame 8 movably connected to the surface of the side away from the positioning double card block 401.

[0029] The above solution is adopted: by setting the positioning card frame 8, when the positioning card frame 8 moves, it can drive the clamping plate 9 to move. The cooperation between the positioning card frame 8 and the positioning card shell 3 has a limiting effect on the movement position of the clamping plate 9.

[0030] refer to Figure 2 A clamping plate 9 is fixedly connected to the surface of the positioning card frame 8.

[0031] The above scheme is adopted: by setting clamping disks 9, when the surfaces of all four clamping disks 9 are in contact with the surface of the concrete specimen, the position of the concrete specimen will be restricted.

[0032] refer to Figure 3 The bottom of the positioning card frame 8 is provided with several card block slots 10 that cooperate with the positioning double card block 401, and the surface of the positioning double card block 401 contacts the inner cavity of the card block slot 10.

[0033] The above solution is adopted: by setting the locking slot 10, when the clamping disk 9 moves to the appropriate position, the cooperating rotating ring 7 is released, and the restoring force generated by the spring 403 returning to its shape will drive the positioning double locking block 401 to be locked into the inner cavity of the locking slot 10. The cooperation of the positioning double locking block 401 and the locking slot 10 has a limiting effect on the position of the clamping disk 9.

[0034] The working principle of this utility model:

[0035] When using the concrete testing machine 1, if a more convenient and stable positioning of the concrete specimen is required, the user first places the concrete specimen on the top of the test bench 2, then rotates the mating ring 7, causing it to rotate via the shaft. As the mating ring 7 rotates, it generates a compressive force on the mating cylinder 6. This compressive force causes the mating double-locking block 401 to move downwards. When the mating double-locking block 401 moves, it causes the locking hole 402 to move along the surface of the locking plate 5. Simultaneously, the force generated by the movement of the mating double-locking block 401 causes the spring 403 to undergo elastic deformation. When the mating double-locking block 401 has fully moved... When the positioning frame 8 moves to the inner cavity of the positioning clasp 3, it moves closer to the concrete specimen. When the positioning frame 8 moves, it will drive the clamping plate 9 to move. When the surface of the clamping plate 9 is in close contact with the surface of the concrete specimen, the cooperating ring 7 is released. The restoring force generated by the spring 403 returning to its shape will drive the positioning double clasp 401 to be inserted into the inner cavity of the clasp groove 10. The cooperation of the positioning double clasp 401 and the clasp groove 10 has a limiting effect on the position of the positioning frame 8 and the clamping plate 9. The setting of the clamping plate 9 has a limiting effect on the position of the concrete specimen. At this time, the concrete testing machine 1 completes a more convenient and stable positioning of the concrete specimen.

[0036] In summary, this concrete compressive strength data acquisition and testing device, through the coordinated use of positioning device 4, positioning double clamping block 401, clamping hole 402, spring 403, and clamping block groove 10, solves the problem that existing concrete testing machines, used for testing concrete performance, require placing concrete specimens on a test platform and then the machine body to compress the concrete specimens. To prevent measurement errors caused by uneven force on the concrete specimens, positioning of the concrete specimens is necessary. Typically, concrete testing machines use bolts to adjust the position of the clamping parts for positioning. However, during use, due to factors such as vibration, the bolts may gradually loosen, causing changes in the position of the clamping parts and affecting their stability. Furthermore, the bolt operation process is relatively complex. Existing concrete testing machines lack a more convenient and stable component for positioning concrete specimens.
