Description

Technical Field

[0001] This utility model relates to the field of cement test block strength testing, and in particular to a multi-station pressure application device for cement test block strength testing. Background Technology

[0002] Compressive strength testing is used to assess the load-bearing capacity of concrete blocks under compression. Flexural strength testing tests the flexural properties of concrete blocks under bending. Density testing measures the mass per unit volume of concrete blocks. Cement blocks require strength testing devices during use.

[0003] Traditional cement test blocks cannot be subjected to multi-station pressure testing during strength testing; they can only be tested individually, resulting in low testing efficiency and the inability to demold quickly, requiring manual demolding.

[0004] Therefore, it is necessary to provide a multi-station pressure application device for testing the strength of cement test blocks to solve the above-mentioned technical problems. The information disclosed in this background section is only intended to enhance the understanding of the overall background of this utility model, and is not necessarily to be regarded as an admission or to imply in any way that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0020] 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.

[0021] Example 1:

[0022] Please see Figure 1-4 This utility model provides a technical solution: a multi-station pressure device for testing the strength of cement test blocks, including a support platform 1, with upright plates 2 on both sides of the upper end of the support platform 1, a horizontal plate 3 installed on the upper inner side of the upright plate 2, a hydraulic cylinder 4 installed on the upper end of the horizontal plate 3, a connecting plate 5 installed through the lower end of the hydraulic cylinder 4 and penetrating the lower end of the horizontal plate 3, and strength testing punch blocks 6 installed sequentially from left to right on the lower end of the connecting plate 5, and a test frame 7 installed sequentially from left to right on the upper end of the support platform 1, with a buffer provided in the inner cavity of the test frame 7. The upper end of the shock assembly 8 is equipped with a cement test placement frame 9, and the upper end of the cement test placement frame 9 passes through the upper end of the test frame 7. The shock assembly 8 includes a buffer plate 10, a buffer column 11, a shock-absorbing spring 12, and a spring shock absorber 13. The lower end of the buffer column 11 is fixed to the upper end of the buffer plate 10, the upper end of the buffer column 11 is fixed to the lower end of the cement test placement frame 9, the upper end of the shock-absorbing spring 12 is fixed to the four sides of the lower end of the buffer plate 10, and the lower end of the spring shock absorber 13 is fixed to the lower end of the buffer plate 10.

[0023] In this implementation scheme, the cement test block to be tested is placed in the cement test placement frame 9, and then the hydraulic cylinder 4 is activated. The hydraulic cylinder 4 drives the connecting plate 5 to move downward. The connecting plate 5 drives the sliding block to slide in the inner cavity of the sliding groove 14, which effectively prevents the connecting plate 5 from tilting or shaking when it moves, and increases the stability of the connecting plate 5 when it moves. The connecting plate 5 drives the strength testing stamping block 6 to stamp the cement test block in the cement test placement frame 9 below. The three strength testing stamping blocks 6 can perform strength testing on the three cement test blocks.

[0024] Example 2:

[0025] Please see Figure 1-4As shown, based on Embodiment 1, this utility model provides a technical solution: the lower end of the spring damper 13 is fixed to the front and rear sides of the lower end of the inner cavity of the test frame 7; the number of damping springs 12 is six, and the six damping springs 12 are evenly distributed at the lower end of the inner cavity of the test frame 7; support columns are installed around the lower end of the support platform 1, and a base pad is installed at the lower end of the support columns; a sliding groove 14 is opened on the inner side of the upright plate 2; a sliding block is slidably connected to the inner cavity of the sliding groove 14, and the inner side of the sliding block is fixed to both sides of the connecting plate 5; a cement test block is set at the upper end of the inner cavity of the cement test placement frame 9; the number of cement test placement frames 9 and test frames 7 are three, and the three cement test placement frames 9 and test frames 7 are evenly distributed above the support platform 1.

[0026] In this embodiment: when the strength testing stamping block 6 transmits the force to the buffer column 11 through the cement test placement frame 9, the buffer column 11 transmits the force to the damping spring 12 and the spring damper 13 through the buffer plate 10. The damping spring 12 and the spring damper 13 cancel out the force applied from above. After the stamping test is completed, the strength testing stamping block 6 moves out of one side of the test frame 7. The rapid recovery of the pressure will cause the cement test block and the cement test placement frame 9 to move quickly out of the top of the test frame 7, which plays a role in the rapid demolding of the cement test block.

[0027] The working principle of the multi-station pressure application device for testing the strength of cement test blocks provided by this utility model is as follows:

[0028] Implementation steps for the first innovation point:

[0029] Step 1: Place the cement test block to be tested into the cement test placement frame 9, and then start the hydraulic cylinder 4. The hydraulic cylinder 4 drives the connecting plate 5 to move downward. The connecting plate 5 drives the sliding block to slide in the inner cavity of the sliding groove 14, which effectively prevents the connecting plate 5 from tilting or shaking when it moves, and increases the stability of the connecting plate 5 when it moves.

[0030] Step 2: The connecting plate 5 drives the strength testing stamping block 6 to press the cement test block in the cement test placement frame 9 below. The three strength testing stamping blocks 6 can perform strength testing on the three cement test blocks.

[0031] Implementation steps for the second innovation point:

[0032] Step 1: When the strength test stamping block 6 transmits the force to the buffer column 11 through the cement test placement frame 9, the buffer column 11 transmits the force to the shock-absorbing spring 12 and the spring damper 13 through the buffer plate 10. The shock-absorbing spring 12 and the spring damper 13 cancel out the force applied from above.

[0033] Step 2: After the stamping test is completed, the strength test stamping block 6 is moved out of one side of the test frame 7. The rapid recovery of the pressure will cause the cement test block and the cement test placement frame 9 to move quickly out of the test frame 7, which will play a role in the rapid demolding of the cement test block.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
