Description

Technical Field

[0001] This utility model relates to the field of cement compressive strength testing technology, and in particular to a cement compressive strength testing fixture. Background Technology

[0002] Cement is widely used in modern buildings. Before cement is produced and used, it is necessary to conduct a compressive strength test on cement samples, which requires the use of a cement compressive strength testing machine.

[0003] A search revealed a Chinese patent with publication number CN202222438280.7 that discloses a cement mortar compressive strength testing device. Through the setting of protective plates and protective structures, it can provide full protection during the compressive strength testing process, avoiding accidental injury to the operator from cement splashing after the cement mortar cracks due to pressure. This improves the safety performance of compressive strength testing. Its operation is simple, its structure is ingenious, and it has significant practicality.

[0004] The above-mentioned technical solution has the following drawbacks: although such a cement compressive strength detector can protect against potentially splashed cement through a protective structure during actual use, it is inconvenient to collect cement debris and position the cement sample. Therefore, a cement compressive strength testing fixture is proposed, which can quickly clamp the cement sample, keeping it in the testing position during the testing process and preventing it from shifting and affecting the testing structure. A cleaning component is provided to clean and remove cement debris generated during the testing process, thus facilitating subsequent compressive strength testing of the next cement sample and effectively improving testing efficiency.

[0005] In view of this, this work improves and solves the above problems. Through dedicated research and application of theoretical principles, a technical solution with a reasonable design that can effectively improve the above defects has finally been proposed.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] This utility model provides a cement compressive strength testing fixture that solves the problems mentioned in the background. It can quickly clamp cement samples, keeping them in the testing position during the testing process and preventing them from shifting and affecting the testing structure. It is equipped with a cleaning component to clean and remove cement debris generated during the testing process, thus facilitating subsequent compressive strength testing of the next cement sample and effectively improving testing efficiency.

[0008] The solution of this utility model to solve the above-mentioned technical problems is as follows: A cement compressive strength testing fixture includes a cement compressive strength detector body, a testing bracket, and a clamping frame. The cement compressive strength detector body is fixedly connected to the testing bracket. The cement compressive strength detector body is equipped with a hydraulic cylinder, which is fixedly connected to the testing bracket. A lower pressure block is installed on the drive end of the hydraulic cylinder by screws. A sample placement seat and a load-bearing net are fixedly installed on the testing bracket. A storage drawer is provided inside the testing bracket. An air jet pipe, a partition plate, and a brake stepper motor are fixedly installed on the clamping frame. A bidirectional lead screw is fixedly installed on the drive end of the brake stepper motor. A lead screw nut is threaded onto the outer wall of the bidirectional lead screw. Two lead screw nuts and two sample grippers are provided. The two lead screw nuts and two sample grippers are fixedly connected one to one. A fan is fixedly installed on the testing bracket. The fan is connected to the air jet pipe through a pipe.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the testing bracket is equipped with a debris discharge port, and the load-bearing net is installed inside the debris discharge port. The debris generated by the cement sample during the testing process can be collected by passing it down from the debris discharge port.

[0011] Furthermore, one end of the bidirectional lead screw is rotatably connected to the clamping frame, allowing the bidirectional lead screw to be rotatably connected within the clamping frame.

[0012] Furthermore, the two sample grippers are symmetrically arranged, and each sample gripper has a trapezoidal groove, with an anti-slip pad installed on the inner wall of the trapezoidal groove.

[0013] Furthermore, the clamping frame has a strip-shaped hole corresponding to the sample gripper, and the inner wall of the strip-shaped hole is slidably connected to the sample gripper.

[0014] Furthermore, the jet pipe is inclined on the inner wall of the clamping frame.

[0015] Furthermore, the jet pipe has a rectangular cross-section structure, and a protective net is fixedly installed on the jet pipe.

[0016] Furthermore, the testing bracket is fixedly equipped with a tempered glass protective cover, and the tempered glass protective cover is provided with an opening and closing door.

[0017] This utility model provides a cement compressive strength testing fixture, which has the following advantages:

[0018] 1. The stepper motor of the brake rotates the bidirectional lead screw, which drives the sample grippers on both sides to move through the lead screw nut. The sample grippers on both sides can clamp and position the cement sample, and the cement sample can be stably positioned on the top of the sample holder. The hydraulic cylinder is started to drive the lower pressure block to press down, and the lower pressure block can press down on the cement sample on the top of the sample holder for testing. During the testing process, the tempered glass protective cover can protect against possible flying debris, thereby improving the safety of the testing process.

[0019] 2. After the test is completed, the door can be opened to remove large cement blocks. The fan can be turned on to send air to the jet pipe and spray it out. The airflow from the jet pipe can clean up cement debris that is difficult to clean. Small debris can pass through the load-bearing net and be sent to the storage drawer. The storage drawer can be removed from the test bracket to process the cement debris.

[0020] 3. This cement compressive strength testing fixture can quickly clamp cement samples, keeping them in the testing position during the testing process and preventing them from shifting and affecting the testing structure. It is equipped with a cleaning component to clean and remove cement debris generated during the testing process, thus facilitating subsequent compressive strength testing of the next cement sample and effectively improving testing efficiency.

A storage drawer 7 is provided inside the testing bracket 2. The clamping frame 8 is fixedly equipped with an air jet pipe 9, a partition plate 10, and a brake stepper motor 11. A bidirectional lead screw 12 is fixedly installed on the drive end of the brake stepper motor 11. A lead screw nut 13 is threadedly connected to the outer wall of the bidirectional lead screw 12. Two lead screw nuts 13 and two sample grippers 14 are provided, and the two lead screw nuts 13 and the sample grippers 14 are fixedly connected one to one.

[0034] Preferably, the testing bracket 2 is provided with a debris discharge port, and the load-bearing net 6 is installed in the debris discharge port. The debris generated by the cement sample during the testing process can be collected by passing it down from the debris discharge port.

[0035] Preferably, one end of the bidirectional lead screw 12 is rotatably connected to the clamping frame 8, so that the bidirectional lead screw 12 can be rotatably connected within the clamping frame 8.
