Description

Technical Field

[0001] This invention belongs to the field of cement test block testing technology, and specifically relates to a test block drainage mechanism in a flexural and compressive strength test line. Background Technology

[0002] Cement strength is an important indicator for evaluating cement quality. In order to ensure that the cement poured in buildings is of qualified quality, it is necessary to test the flexural and compressive strength of the cement. That is, to test how much force the cement block is subjected to when it is crushed, so as to determine whether the cement is qualified.

[0003] Before testing, cement test blocks need to be cured in a curing chamber for a period of time. Then, the test blocks are manually removed from the curing chamber and placed into the flexural or compressive strength test chamber for testing.

[0004] Manually handling test blocks is inefficient, especially in batch testing scenarios. Operators need to pick up, move, and place each test block individually, which not only consumes a lot of manpower but also easily leads to chaotic handling order and mixed test block numbers, resulting in incorrect correspondence between test data and test blocks and affecting the orderly progress of the testing work. In addition, after the test blocks have been cured, moisture may remain on the surface, which can easily cause them to slip and fall during manual handling, resulting in test block waste and increased testing costs. Summary of the Invention

[0005] The purpose of this invention is to provide a test block drainage mechanism in a flexural and compressive strength test line, which serves as a connecting device between the test block curing box and the integrated flexural and compressive strength test machine for synthetic reaction frame test blocks, thereby achieving the goal of fully automated testing of large batches of cement test blocks.

[0006] To solve the above technical problems, the present invention provides a test block diversion mechanism in the flexural and compressive strength test line, which serves as a connecting device between the test block curing box and the integrated flexural and compressive strength test machine of the synthetic reaction frame test block. It can automatically move the cured cement test block to the integrated flexural and compressive strength test machine of the synthetic reaction frame test block for flexural and compressive strength performance testing.

[0007] It includes a test block drainage channel, one end of which is connected to a guide block, and the end of the test block drainage channel slides along the inclined guide groove of the guide block.

[0008] A crank connecting rod is also provided in the middle of the test block drainage channel. Under the action of the electric push rod, the crank connecting rod drives the test block drainage channel to rise and fall obliquely, so that one end of it is connected to the test block curing box or the other end is connected to the worktable of the integrated machine for testing the bending and compressive strength of the synthetic reaction frame test block.

[0009] Preferably, a baffle is provided at one end of the test block drainage channel near the integrated testing machine for the flexural and compressive strength of the synthetic reaction frame test block. The movable axis of the baffle also slides along the inclined guide channel. When the test block drainage channel rises to connect with the test block curing box, the baffle automatically lifts up, serving as the lower limit position of the cement test block in the inclined guide channel. When the test block drainage channel descends to connect with the working table of the integrated testing machine for the flexural and compressive strength of the synthetic reaction frame test block, the baffle falls under the action of gravity, facilitating the sliding out of the cement test block.

[0010] Preferably, the test block drainage channel is provided with a trigger punch at one end near the test block curing box. When the test block drainage channel rises to connect with the test block curing box, the trigger that restricts the cement test block inside the test block curing box is pushed, and the test block naturally slides into the test block drainage channel under the action of gravity.

[0011] Preferably, the worktable of the integrated machine for testing the flexural and compressive strength of the synthetic reaction frame test block is provided with a bidirectional synchronous clamping mechanism on both sides. The cement test block is clamped by the bidirectional synchronous clamping mechanism and passes through the flexural position, compressive position and discharge position in sequence.

[0012] Preferably, the bidirectional synchronous clamping mechanism includes two symmetrically arranged synchronous pulley sets and a drive motor that drives the synchronous pulley sets to rotate. Two clamping cylinders are symmetrically installed on the synchronous belts of the two sets of synchronous pulley sets. The cement test block is clamped by the two clamping cylinders and passes through the bending resistance position, the compressive resistance position and the discharge position in the horizontal direction in sequence.

[0013] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include:

[0014] 1. This invention addresses the problems of low efficiency and time-consuming and labor-intensive batch testing in manual sample collection. The flow-guiding mechanism enables the automatic movement of cement samples after curing, eliminating the need for operators to individually grab, transport, and place the samples. This significantly improves the overall efficiency of sample transport and subsequent testing, while reducing manpower input and lowering labor costs.

[0015] 2. This invention utilizes the combination of structures such as the test block drainage channel, crank connecting rod, and electric push rod, along with a bidirectional synchronous clamping mechanism, to drive the test blocks to complete flexural and compressive strength tests and discharge sequentially. This achieves full automation of the entire process of large-scale cement test blocks from curing to testing, eliminating reliance on manual operation and avoiding the decrease in accuracy caused by operator fatigue from long-term repetitive operation. It meets the standardization and refinement requirements of cement strength testing.

[0016] 3. The end of the drainage channel of the test block drainage mechanism is matched with the inclined guide channel of the guide block. The crank connecting rod drives the drainage channel to rise and fall obliquely, which can flexibly achieve precise connection with the curing box and the integrated testing machine. The design of the baffle and trigger punch further ensures the smoothness and stability of the test block transportation. The bidirectional synchronous clamping mechanism ensures that the test block is accurately positioned during the testing process. The overall structural design fits the actual testing scenario, has strong adaptability and reliable operation. Attached Figure Description

[0030] Example

[0031] like Figure 1 and Figure 2 As shown, the present invention provides a test block diversion mechanism in the flexural and compressive strength test line, which serves as a connecting device between the test block curing box 100 and the synthetic reaction frame test block flexural and compressive strength integrated machine 200. It can automatically move the cured cement test block to the synthetic reaction frame test block flexural and compressive strength integrated machine 200 for flexural and compressive strength performance testing.

[0032] For details, please refer to Figure 3-6 It includes a test block drainage channel 1, one end of which is connected to a guide block 2, and the end of the test block drainage channel 1 slides along the inclined guide groove 21 of the guide block 2; a crank connecting rod 3 is also provided in the middle of the test block drainage channel 1, and the crank connecting rod 3 drives the test block drainage channel 1 to rise and fall obliquely under the action of an electric push rod 4, so that one end of it is connected to the test block curing box 100 or the other end is connected to the work surface of the integrated machine 200 for testing the bending and compressive strength of the synthetic reaction frame test block.

[0033] Furthermore, a baffle 5 is provided at one end of the test block drainage channel 1 near the integrated testing machine 200 for the flexural and compressive strength of the synthetic reaction frame test block. The movable axis of the baffle 5 also slides along the inclined guide groove 21. When the test block drainage channel 1 rises to connect with the test block curing box 100, the baffle 5 automatically lifts up, serving as the lower limit of the cement test block in the inclined guide groove 21. When the test block drainage channel 1 descends to connect with the worktable of the integrated testing machine 200 for the flexural and compressive strength of the synthetic reaction frame test block, the baffle 5 falls down under the action of gravity, facilitating the sliding out of the cement test block.

[0034] Furthermore, a trigger block 6 is provided at one end of the test block drainage channel 1 near the test block curing box 100. When the test block drainage channel 1 rises to connect with the test block curing box 100, the trigger that restricts the cement test block inside the test block curing box 100 is pushed, and under the action of gravity, it naturally slides into the test block drainage channel 1.

[0035] The end of the flow channel of the test block flow diversion mechanism is matched with the inclined guide channel of the guide block. The crank connecting rod drives the flow channel to rise and fall obliquely, which can flexibly achieve precise connection with the curing box and the integrated testing machine. The design of the baffle and trigger punch further ensures the smoothness and stability of the test block transfer. The bidirectional synchronous clamping mechanism ensures that the test block is accurately positioned during the testing process. The overall structural design fits the actual testing scenario, with strong adaptability and reliable operation.

[0036] In this embodiment, please refer to Figure 7 and Figure 8 The worktable of the integrated machine 200 for testing the bending and compressive strength of the synthetic reaction frame test block is provided with a bidirectional synchronous clamping mechanism 7 on both sides. The cement test block is clamped by the bidirectional synchronous clamping mechanism 7 and passes through the bending position, the compressive position and the discharge position in sequence.

[0037] Specifically, the bidirectional synchronous clamping mechanism 7 includes two symmetrically arranged synchronous pulley sets 71 and a drive motor 72 that drives the synchronous pulley sets 71 to operate. Two clamping cylinders 73 are symmetrically installed on the synchronous belts of the two sets of synchronous pulley sets 71. The cement test block is clamped by the two clamping cylinders 73 and passes through the bending resistance position, the compressive resistance position and the discharge position in the horizontal direction in sequence.

[0038] This test block diversion mechanism, through the cooperation of test block diversion channels, crank connecting rods, electric push rods and other structures, combined with a two-way synchronous clamping mechanism, drives the test blocks to complete flexural and compressive strength tests and discharge in sequence. It realizes the full automation of the process of large-scale cement test blocks from curing to testing, eliminating the dependence on manual operation, avoiding the decrease in accuracy caused by operator fatigue from long-term repetitive operation, and meeting the standardization and precision requirements of cement strength testing.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
