Description

Technical Field

[0001] This utility model relates to a concrete strength testing device, belonging to the technical field of concrete testing devices. Background Technology

[0002] Concrete is one of the most widely used building materials in modern construction engineering, and its compressive strength is the most critical indicator for evaluating concrete quality and structural safety. Therefore, concrete compressive strength testing technology is of irreplaceable importance for ensuring project quality, controlling construction progress, and conducting structural safety assessments.

[0003] The industry commonly uses the standard test block method for testing. The specific procedure involves placing a prepared concrete test block on a compression testing machine and applying pressure at a specified rate until the block crushes and fails. However, in practical applications, this method has been found to have certain drawbacks:

[0004] The compression testing machine lacks an automatic cleaning device, requiring manual cleaning of the crushed concrete fragments and debris on the test platform after the experiment. This involves manually removing the concrete blocks by hand and then using a brush to sweep away the debris from the worktable. Due to the weight of the concrete, manual cleaning is both time-consuming and labor-intensive, impacting the efficiency of subsequent concrete test block experiments. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a concrete strength testing device that realizes the integrated operation of strength testing of concrete samples and post-test debris cleaning, saving manpower and improving test efficiency.

[0006] The present invention relates to a concrete strength testing device, comprising: a protective cover covering the worktable of a press, the actuator of the press being able to pass through the protective cover, and a first support frame and a second support frame provided on the side of the press.

[0007] The protective cover is equipped with a push block inside, which can push debris out of the protective cover; the first support frame is equipped with a drive component, the movable part of which can pass through the protective cover to drive the push block to move.

[0008] The second support frame is equipped with a conveyor belt, and the conveyor belt is equipped with a material box; the material box can receive the debris that is cleaned out of the protective cover by the push block.

[0009] Furthermore, the protective cover includes: a cover body, with a push port and a discharge port on opposite sides of the cover body.

[0010] A baffle is slidably provided on the push port, and the movable part of the drive component can pass through the push port and the baffle to enter the interior of the cover.

[0011] A curtain is provided on the inside of the discharge port, and a conveyor cylinder is provided on the outside of the discharge port; the output end of the conveyor cylinder can be connected to the material box.

[0012] Furthermore, the cover is equipped with a sample feeding port, which is hinged with a protective door.

[0013] Furthermore, the push block includes: a main body, the bottom of which is provided with a chip discharge groove, a cleaning brush and a wiping pad from the inside to the outside; a liquid guide strip is connected to the wiping pad.

[0014] The main body is equipped with a liquid storage tank and a drainage channel. The liquid guide strip can pass through the drainage channel to transfer the liquid in the liquid storage tank to the wiping pad.

[0015] Furthermore, several rollers are hinged to the conveyor belt, and the material box can slide on the rollers.

[0016] Furthermore, the fluid guide strip is made of cotton yarn.

[0017] The advantages of this utility model compared with the prior art are:

[0018] After the press finishes testing the concrete, the drive unit can drive the push block to quickly push the concrete fragments along the press's worktable, causing them to fall into the material box for collection. This avoids manual cleaning of the concrete fragments and quickly prepares the concrete test blocks for subsequent testing, greatly improving testing efficiency. Simultaneously, as the push block moves, the cleaning brush and wiping pad on it can clean and wipe the press's worktable, keeping it clean and facilitating subsequent testing.

A first support frame 4 and a second support frame 6 are provided on the side of the press 1. The actuator is the press head of the press, such as... Figure 1 , Figure 2 As shown.

[0034] The protective cover 2 is equipped with a push block 5 inside, which can push debris out of the protective cover 2; the first support frame 4 is equipped with a drive component 3, and the movable part of the drive component 3 can pass through the protective cover 2 to drive the push block 5 to move.

[0035] Specifically, in this embodiment, the protective cover 2 is transparent and made of acrylic. In this embodiment, the driving component 3 is a cylinder; preferably, the driving component 3 can also be an electric cylinder. In this embodiment, one end of the piston rod of the cylinder is fixedly connected to the outside of the pushing block 5, such as... Figure 4 As shown.

[0036] The second support frame 6 is equipped with a conveyor belt 7, and the conveyor belt 7 is equipped with a material box 8; the material box 8 can receive the debris that is cleaned out of the protective cover 2 by the push block 5.

[0037] Specifically, the protective cover 2 includes: a cover body 201, with a push port 202 and a discharge port 203 on opposite sides of the cover body 201, such as... Figure 3 As shown.

[0038] A baffle 204 is slidably provided on the push port 202, and the movable part of the drive member 3 can pass through the push port 202 and the baffle 204 to enter the interior of the cover 201.

[0039] A curtain 205 is provided on the inner side of the discharge port 203, and a conveying cylinder 207 is provided on the outer side of the discharge port 203; the output end of the conveying cylinder 207 can be connected to the material box 8.

[0040] Specifically, the cover 201 is also equipped with a sample feeding port, and a protective door 206 is hinged to the sample feeding port.

[0041] Specifically, the push block 5 includes: a main body 501, and the bottom of the main body 501 is provided with a chip discharge groove 502, a cleaning brush 503 and a wiping pad 507 from the inside to the outside; a liquid guide strip 505 is connected to the wiping pad 507.

[0042] The main body 501 is provided with a liquid storage tank 504 and a drainage channel 506. The liquid guide strip 505 can pass through the drainage channel 506 to transfer the liquid in the liquid storage tank 504 to the wiping pad 507.

[0043] In this embodiment, the main body 501 is arc-shaped, such as... Figure 2 As shown; during operation, the larger concrete block is first pushed by the inner side of the main body 501 to the smaller concrete blocks and debris on the worktable of the press machine 1, which then fall into the chip discharge trough 502 and are cleaned by the adjacent cleaning brush 503. After cleaning, the dust remaining on the worktable is wiped off by the adjacent wiping pad 507.

[0044] Specifically, several rollers are hinged to the conveyor 7, and the material box 8 can slide on the rollers. After the material box 8 is loaded with concrete fragments, it is manually pushed along the conveyor 7.

[0045] Specifically, the liquid guide strip 505 is made of cotton yarn, and in this embodiment, the liquid contained in the liquid storage tank 504 is water.

[0046] The specific working principle of this utility model is as follows:

[0047] During the test, the protective door 206 was manually opened, and the concrete sample 9 was placed onto the worktable of the press 1. The protective door 206 was then closed, and the press 1 was started to test the concrete sample 9. After testing, the drive unit 3 was activated, its moving part passing through the push port 202 on the side of the protective cover 2 and pushing the internal push block 5. Larger concrete blocks were directly pushed by the push block 5, while smaller concrete blocks and debris close to the worktable of the press 1 fell into the chip discharge trough 502 and were cleaned by the cleaning brush 503. Simultaneously, the liquid guide strip 505 continuously transported the liquid in the storage tank 504 to the wiping pad 507 through capillary action, wetting and wiping the worktable to prevent dust from being stirred up. As the push block 5 continued to move, the accumulated concrete debris was pushed towards the discharge port 203 and fell into the outer conveyor cylinder 207 through the curtain 205. The debris slid down the conveyor cylinder 207 into the material box 8 on the lower conveyor 7, completing the collection. Throughout the process, the protective door 206 of the protective cover 2 can be used to deliver the workpiece and also maintain a sealed safety to prevent the debris of the concrete sample block 9 from splashing outwards during the testing process.
