Description

Technical Field

[0001] This utility model relates to the field of mechanical property testing technology, specifically to a mechanical property testing device for self-compacting concrete. Background Technology

[0002] Self-compacting concrete refers to concrete that can flow and compact under its own weight, completely filling the formwork even with dense reinforcing steel, while achieving good homogeneity, and without requiring additional vibration.

[0003] For example, the mechanical property testing equipment for ion-cured products with announcement number "CN218212447U" utilizes a combination of a protective cover, a protective door, a slider, a slide groove, a limiting mechanism, and a clamping mechanism. The protective cover and door work together to reduce safety hazards, while the slider, slide groove, and limiting mechanism securely fasten the protective cover to the testing instrument. The clamping mechanism also secures the protective door to the protective cover. This solves the problem of existing testing instruments requiring damage to the ion-cured product before performance testing, which could lead to waste splashing and injury to the user. However, after each test, the workpiece breaks, requiring workers to clean the inside of the protective door for the next test, increasing their physical exertion. Utility Model Content

[0004] The purpose of this invention is to solve the problem that after each test, the workpiece will break, so the staff needs to clean the inside of the protective door to facilitate the next test, which increases the physical exertion of the staff. Therefore, this invention proposes a self-compacting concrete mechanical property testing device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a mechanical property testing device for self-compacting concrete, including a testing chamber, a control console on the left side of the testing chamber, a hydraulic cylinder electrically connected to the control console, two hydraulic cylinders fixedly connected to the inner wall of the testing chamber, the lower ends of the hydraulic cylinders being fixedly connected to a pressure plate, a cleaning mechanism inside the testing chamber, and a bending plate fixedly connected to the left side of the outer wall of the testing chamber.

[0007] Preferably, the lower inner wall of the testing box is machined with a sliding groove, and the outer wall of the testing box is equipped with a sliding door.

[0008] Preferably, the cleaning mechanism includes an electric telescopic rod, a funnel, and a collection box. The output end of the electric telescopic rod is fixedly connected to a scraper, and the outer wall of the scraper is in contact with the detection box.

[0009] Preferably, the inner walls of the scraper are slidably connected to the slide rod, and both ends of the slide rod are fixedly connected to the detection box.

[0010] Preferably, the outer walls of the funnels are fixedly connected to the detection box, the outer walls of the collection box are slidably connected to the chute, and the electric telescopic rod is electrically connected to the control console.

[0011] The present invention proposes a self-compacting concrete mechanical property testing device, the advantages of which are as follows: through the cooperation of the cleaning mechanism and the testing box, the output end of the electric telescopic rod extends and drives the scraper to move to the right. The scraper moves to the right and is limited by the sliding rod to move linearly. The scraper pushes the damaged self-compacting concrete cube standard specimen to the funnel on the right. The funnel collects the fragments of the self-compacting concrete cube standard specimen into the collection box. The electric telescopic rod retracts and drives the scraper to move to the left to clean the inside of the testing box again. The cleaning mechanism cleans the inside of the testing box, eliminating the need for manual cleaning by the staff and saving their physical strength. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] See attached document Figure 1-5 :

[0020] In this embodiment, a self-compacting concrete mechanical property testing device includes a test box 1, a control console 6 on the left side of the test box 1, a hydraulic cylinder 4 electrically connected to the control console 6, and two hydraulic cylinders 4 fixedly connected to the inner wall of the test box 1. The lower ends of the hydraulic cylinders 4 are fixedly connected to the pressure plate 5, and the output ends of the hydraulic cylinders 4 extend and retract to drive the pressure plate 5 to move.

[0021] The testing box 1 is equipped with a cleaning mechanism 2 inside. A curved plate 3 is fixedly connected to the left side of the outer wall of the testing box 1. A sliding groove 7 is machined on the lower inner wall of the testing box 1. A sliding door 8 is installed on the outer wall of the testing box 1. The sliding door 8 is fastened to the testing box 1 by a latch.

[0022] See attached document Figure 1-5 :

[0023] The cleaning mechanism 2 includes an electric telescopic rod 201, a funnel 204, and a collection box 205. The output end of the electric telescopic rod 201 is fixedly connected to a scraper 202. The extension and retraction of the output end of the electric telescopic rod 201 drives the scraper 202 to move. The outer wall of the scraper 202 is in contact with the detection box 1. The movement of the scraper 202 can scrape off the debris on the detection box 1. The inner wall of the scraper 202 is slidably connected to the slide rod 203.

[0024] The slide bar 203 provides sliding support for the scraper 202. Both ends of the slide bar 203 are fixedly connected to the detection box 1. The outer wall of the funnel 204 is fixedly connected to the detection box 1. The funnel 204 can collect debris and flow into the collection box 205, preventing it from flowing into the gap between the collection box 205 and the detection box 1. The outer wall of the collection box 205 is slidably connected to the chute 7.

[0025] Working principle:

[0026] The mechanical properties of self-compacting concrete are tested using mechanical property testing equipment.

[0027] Work process:

[0028] First, open sliding door 8. Then, the staff places the prepared self-compacting concrete cube standard specimen into testing box 1. The self-compacting concrete cube standard specimen is placed under pressure plate 5 (e.g., Figure 2 Then close the sliding door 8 (the sliding door 8 is equipped with a latch, which can be used to fix the sliding door 8), and then use the control panel 6 (such as...) Figure 1 Simultaneously, hydraulic cylinder 4 is activated (the control console 6 achieves synchronous movement of hydraulic cylinder 4 through encoders, etc.), and the output end of hydraulic cylinder 4 extends and retracts, causing pressure plate 5 to move downwards (e.g., Figure 2The pressure plate 5 moves downward to compress the self-compacting concrete cube standard specimen. The self-compacting concrete cube standard specimen will exhibit elastic deformation, plastic deformation, crack propagation stage and failure stage. The pressure applied by the hydraulic cylinder 4 is reflected on the display on the control console 6 at different stages, and the mechanical properties of the self-compacting concrete cube standard specimen can be known.

[0029] Cleaning process:

[0030] After the test was completed, the staff controlled the hydraulic cylinder 4 to reset via the control console 6, and then controlled the electric telescopic rod 201 (as shown in the image). Figure 2 The output end of the electric telescopic rod 201 extends and drives the scraper 202 to move to the right. The scraper 202 moves to the right and is limited by the sliding rod 203 to move in a straight line. The scraper 202 pushes the damaged self-compacting concrete cube standard specimen to the funnel 204 on the right. The funnel 204 collects the fragments of the self-compacting concrete cube standard specimen into the collection box 205. When the scraper 202 moves to the rightmost end;

[0031] Then, the electric telescopic rod 201 is retracted, which drives the scraper 202 to move to the left, cleaning the inside of the test box 1 again. The debris of the self-compacting concrete cube standard specimen that was not cleaned in the first cleaning is pushed to the funnel 204 on the left, thus cleaning the inside of the test box 1. (In the next processing, the staff can first clean the inner wall of the test box 1 with an air gun to prevent some dust from not being scraped off.) When the collection box 205 is full, the staff can pull the collection box 205 outward through the handle on the outer wall of the collection box 205. The collection box 205 moves linearly under the limit of the slide groove 7 until the collection box 205 is separated from the test box 1, and the debris of the self-compacting concrete cube standard specimen in the collection box 205 can be disposed of.

[0032] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
