Description

Technical Field

[0001] The present invention relates to the technical field of concrete test block detection, and in particular to an automatic loading and unloading device for concrete test blocks and a full-automatic detection system. Background Art

[0002] Concrete is one of the main materials used in modern engineering structures. According to relevant regulations, the strength grade of concrete should be divided according to the standard value of the cube compressive strength of concrete. In China, a cube of 150mm×150mm×150mm is used as the standard size specimen for concrete compressive strength. The results of non-standard size specimens should be multiplied by a conversion factor to be converted into the standard cube strength. For the axial compressive strength of concrete, it is determined according to the prism axial compressive strength. In China, a prism of 150mm×150mm×300mm is used as the standard size specimen for axial compressive strength, and the results of non-standard size specimens are converted after being folded to the standard prism compressive strength.

[0003] The concrete test blocks of existing concrete presses are usually loaded manually or picked up by a manipulator for loading. The loading efficiency is low, and each concrete press needs to be equipped with a manipulator, resulting in a high test cost and it is difficult to achieve batch tests. Summary of the Invention

[0037] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] As Figure 1-4 shown, an automatic loading and unloading device 100 for concrete test blocks proposed in an embodiment of the present invention includes a base 1 and a loading and unloading mechanism 2. The loading and unloading mechanism 2 can move back and forth along the length direction of the base 1 and is used to drive the concrete test blocks 200 placed on the base 1 to move back and forth. Among them, the loading and unloading mechanism 2 includes a frame 201, two support arms 202, a swing arm 203 and a driving member 204 movably connected to the end of each support arm 202. The two support arms 202 are arranged on both sides of the frame 201, and the concrete test blocks 200 are placed between the two support arms 202. The driving member 204 is installed in the frame 201, and the driving member 204 drives the frame 201 and the support arms 202 arranged on both sides of the frame 201 to move back and forth. The swing arm 203 is movably connected to the end of the support arm 202, and the swing arm 203 includes a first state and a second state. In the first state, the swing arm 203 is parallel to the support arm 202 and is used for feeding and discharging the concrete test blocks 200. In the second state, the swing arm 203 turns inward and can drive the concrete test blocks 200 to move together when the loading and unloading mechanism 2 moves.

[0039] Specifically, racks 101 are arranged on both sides of the base 1, a driving gear 205 is arranged on the driving member 204, and the driving gear 205 meshes with the racks 101. The driving member 204 drives the driving gear 205 to rotate, thereby driving the loading and unloading mechanism 2 to move back and forth on the base 1.

[0040] In some embodiments, the racks 101 extend along the length direction of the base 1, so that the loading and unloading mechanism 2 can move back and forth along the length direction of the base 1.

[0041] In some embodiments, slide rails are provided on both sides of the base 1, a slider is provided on the driving member 204, and the slider is matched with the slide rail. The driving member 204 drives the slider to slide along the slide rail, so as to drive the loading and unloading mechanism 2 to move back and forth on the base 1.

[0042] Specifically, the swing arm 203 is rotatably connected to the end of the support arm 202 through a rotating shaft. In the first state, the swing arm 203 rotates to be parallel to the support arm 202; in the second state, the swing arm 203 flips inward to be perpendicular to the support arm 202.

[0043] Furthermore, a first guiding portion 2031 and a second guiding portion 2032 are provided at one end of the swing arm 203 close to the support arm 202, so that the rotation of the swing arm 203 automatically rotates in a specified direction.

[0044] Specifically, as Figures 3-5 shown, a first guiding member 3 and a second guiding member 4 are provided at one end of the support arm 202 close to the swing arm 203; the first guiding member 3 contacts the first guiding portion 2031, and the second guiding member 4 contacts the second guiding portion 2032.

[0045] In some embodiments, both the first guiding member 3 and the second guiding member 4 are bearings, so that the first guiding portion 2031 and the second guiding portion 2032 respectively rotate along the outer ring of the bearing.

[0046] Specifically, as Figure 5 and Figure 6 shown, a positioning groove 2033 is formed in the second guiding portion 2032, and a positioning block matching the positioning groove 2033 is provided on the support arm 202, so as to realize automatic switching of the swing arm 203 between the first state and the second state.

[0047] Specifically, as Figures 1-5 shown, a detachable push head 5 is provided at one end of the swing arm 203 far from the support arm 202. By replacing the push head 5 with different lengths, it is possible to adapt to concrete test blocks 200 of different sizes. First scrapers 6 are provided at the bottoms of the frame 201 and the support arm 202 for clearing concrete fragments on the base 1. The concrete test block 200 may break after the test, and the remaining fragments will affect the next test. Therefore, it is necessary to clear the remaining fragments through the first scraper 6 to achieve full automation of the detection.

[0048] As Figure 7 and Figure 8As shown in the figure, an embodiment of the present invention further provides a fully automatic concrete test block detection system, which includes the loading and unloading device 100, multiple presses 300, multiple gripping devices 400, multiple transfer devices 500, an outfeed conveyor belt device 600, and a feeding conveyor line 700; each press 300 is equipped with a set of the loading and unloading device 100, a gripping device 400, and a transfer device 500. The gripping device 400 is a liftable jaw, which grabs the concrete test block 200 onto the loading and unloading device 100, and then the loading and unloading device 100 moves the concrete test block 200 to directly below the press 300; the feeding conveyor line 700 is used to batch load the concrete test blocks 200 for detection; the transfer device 500 is a liftable jaw, which can grab the tested concrete test block 200 onto the outfeed conveyor belt device 600, and after collection, they are stored in the warehouse uniformly.

[0049] Specifically, a sample determination platform 800 is provided between each press 300 and the outfeed conveyor belt device 600. The concrete test block 200 is pushed to the sample determination platform 800 by the loading and unloading device 100 to determine whether it is qualified on the sample determination platform 800.

[0050] Specifically, a second scraping plate 7 is provided on the loading and unloading mechanism 2. The second scraping plate 7 moves with the loading and unloading mechanism 2, and can remove the debris adhering to the surface of the press head of the press 300, avoiding the influence of debris residue on the accuracy of the next detection.

[0051] In use, first, a batch of concrete test blocks 200 to be tested are placed on the feeding conveyor line 700 by a transporter and transported through the feeding conveyor line 700. Then, the row of concrete test blocks 200 are successively grabbed by the grabbing device 400 and moved to the preparation area of the corresponding press 300, and then moved to the preparation area by the loading and unloading mechanism 2. At this time, the swing arm 203 is parallel to the support arm 202 and stops until the end of the support arm 202 exceeds the concrete test block 200. At the same time, the swing arm 203 flips inward to be perpendicular to the support arm 202. At this time, the loading and unloading mechanism 2 resets and drives the concrete test block 200 to move to directly below the press head of the press 300 for waiting for testing. Then, the press head of the press 300 presses down to contact the concrete test block 200 and applies a certain pressure to the concrete test block 200 for testing. After the testing is completed, the loading and unloading mechanism 2 still drives the concrete test block 200 to move towards the sample judgment platform 800, and the broken particles during the testing process will be removed by the first scraper 6. Whether the concrete test block 200 is qualified is judged on the sample judgment platform 800. The qualified ones are grabbed by the transfer device 500 and placed on the discharge conveyor belt device 600, and are collected and stored in the warehouse uniformly after collection. The unqualified ones are taken out manually for re-inspection. Finally, the swing arm 203 returns to the position parallel to the support arm 202 and waits for the next feeding.

[0052] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the examples, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
