Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete slump detection device. Background Art

[0002] Slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including the water retention, fluidity and cohesion of concrete. Slump is a quantitative indicator to measure its degree, which is used to judge whether the construction can proceed normally.

[0003] There are some collapse detection devices in the prior art. For example, the utility model patent document with authorization announcement number "CN220340220U" and patent name "A concrete collapse detection device" discloses a concrete collapse detection device, which includes a measuring cylinder, a tamping rod and a scraper.

[0004] When concrete collapse detection is required, concrete is poured into the measuring barrel, and then a tamping rod is taken out to tamp the concrete up and down along the wall of the measuring barrel, and then a scraper is used to scrape off the excess concrete and read the value, and then the measuring barrel is removed and the height of the concrete is measured at a prescribed time, and the difference between the two values ​​is the collapse of the concrete. However, some existing collapse detection devices do not position the measuring barrel, and when the measuring barrel is knocked, it may be displaced, thereby affecting the detection result of the concrete. Utility Model Content

[0005] The utility model aims to address the deficiencies of the prior art and propose a concrete collapse detection device to solve the technical problem mentioned in the background technology that some of the existing collapse detection devices fail to position the collapse bucket, which may cause the collapse bucket to shift when it is struck, thereby affecting the detection result of the concrete.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A concrete collapse detection device comprises a base plate and a universal wheel at the bottom thereof, wherein a tray is arranged on the base plate, a collapse bucket is placed on the tray, two opposite supporting members are fixedly arranged on the tray, a first cylinder is fixedly arranged on each supporting member, an arc-shaped clamping block is fixedly arranged on the telescopic end of each first cylinder, two clamping blocks are relatively abutted against the collapse bucket, a vertically movable scraper is arranged on the base plate, a vertical scale is arranged at one end of the scraper, and the scale is perpendicular to the scraper.

[0008] Working principle:

[0009] First, the operator places the slump bucket on the tray, and then uses the two first cylinders to make the two clamping blocks contact the slump bucket, and then pours concrete into the slump bucket until the concrete is flush with the top of the slump bucket. At this time, the slump bucket can be knocked manually or with the help of an external drive device. Then, the operator lifts the slump bucket and separates it from the concrete, and pushes the scraper toward the collapsed concrete, while moving the scraper vertically, so that the scraper moves from the top surface of the collapsed concrete to smooth it, and records the scale on the ruler at this time. The height of the slump bucket is subtracted from the scale of the ruler after the concrete collapses, and the slump of the concrete can be obtained.

[0010] The beneficial effects of the utility model are:

[0011] During the use of the utility model, the operator positions and clamps the slump bucket by means of the clamping block, thereby preventing the slump bucket from shifting when struck, thereby affecting the accuracy of the concrete slump, and making the slump detection result of the concrete more accurate.

[0017] During the use of the utility model, the operator positions and clamps the slump bucket 4 through the clamping block 7, so as to prevent the slump bucket 4 from shifting when struck, thereby affecting the accuracy of the concrete slump, and making the slump detection result of the concrete more accurate.

[0018] like Figure 1 As shown, a rotating chamber 10 is provided in the bottom plate 1, a first motor 11 is fixedly provided at the bottom of the bottom plate 1, a rotating shaft 12 is fixedly provided at the output end of the first motor 11, the rotating shaft 12 is rotatably passed through the bottom plate 1 and is fixedly connected to the bottom of the tray 3, a part of the shaft 12 is provided in the rotating chamber 10, and a knocking head 13 is provided on the bottom plate 1 which can move vertically to knock the collapse bucket 4. Figure 1 As shown, a support block 14 is fixedly provided on the base plate 1, a first gear 15 located in the rotating chamber 10 is fixedly provided on the rotating shaft 12, a second gear 16 is meshed on the first gear 15, a first screw rod 17 passing through the base plate 1 and the support block 14 is fixedly provided on the second gear 16, the rod section of the first screw rod 17 passing through the base plate 1 and the support block 14 is a smooth round rod section, a limiting rod 18 parallel to the first screw rod 17 is fixedly provided on the support block 14, a first shaft sleeve 19 is threadedly provided on the first screw rod 17, a first sliding block 20 is slidably provided on the limiting rod 18, a connecting piece 21 is fixedly provided between the first shaft sleeve 19 and the first sliding block 20, a limiting plate 22 is fixedly provided between the limiting rod 18 and the top of the first screw rod 17, and the knocking head 13 is provided on the first shaft sleeve 19. As shown Figure 1 and Figure 2As shown, a sleeve 23 is fixedly provided on the first sleeve 19, a spring 24 is fixedly provided in the sleeve 23, the knocking head 13 is slidably provided in the sleeve 23, and one end of the knocking head 13 is fixedly connected to the spring 24, a plurality of transverse annular knocking grooves 36 are provided on the outer wall of the slump bucket 4 in the vertical direction, the annular bottom of the knocking groove 36 is concave smaller than the annular top, the knocking head 13 can slide from the side wall of the slump bucket 4 into the knocking groove 36, and knock the side wall of the slump bucket 4, and the inner wall of the slump bucket 4 is a smooth cambered surface. After pouring concrete into the slump bucket 4, the operator starts the first motor 11, and the output end of the first motor 11 drives the first gear 15, the tray 3 and the slump bucket 4 thereon to rotate through the first rotating shaft 12, so that the concrete in the slump bucket 4 rotates smoothly. The rotating first gear 15 drives the first screw 17 to rotate through the second gear 16 meshing therewith, so that the first sleeve 19 drives the sleeve 23 and the knocking head 13 to slide vertically on the first screw 17, and the first slider 20 slides vertically on the limit rod 18 with the first sleeve 19 through the connecting piece 21. In this process, the spring 24 in the sleeve 23 pushes the knocking head 13, so that the knocking head 13 continues to abut against the outer wall of the collapse bucket 4. When the knocking head 13 moves vertically to the knocking groove 36, the spring 24 pushes the knocking head 13, so that the knocking head 13 abuts against the knocking groove 36 for knocking, and then the first sleeve 19 drives the knocking head 13 to slide vertically through the sleeve 23 and abut and move out of the knocking groove 36, thereby achieving the knocking of the collapse bucket 4. This design method rotates the collapse bucket 4 through the first motor 11, and the knocking head 13 moves vertically to knock through the cooperation of the second gear 16 and the first screw rod 17. The linkage is good, and repeated manual knocking and leveling of the concrete in the collapse bucket 4 is avoided, which saves manpower and has good practicality. The knocking groove 36 is also used to enable the knocking head 13 to better knock the collapse bucket 4 and slide out of the knocking groove 36. The structure is simple and the effect is good.

[0019] like Figure 1As shown, the slump bucket 4 also includes a bearing 25, a ring sleeve 26 is fixedly provided on the slump bucket 4, the center hole of the bearing 25 is fixedly connected to the outer wall of the ring sleeve 26, a connecting rod 27 is fixedly provided on the outer wall of the bearing 25, and a second cylinder 28 with a telescopic end vertically upward is fixedly provided on the bottom plate 1, and the connecting rod 27 is fixedly provided on the telescopic end of the second cylinder 28. When the slump bucket 4 rotates, the inner wall of the bearing 25 on it is driven to rotate relative to the outer wall of the bearing 25 on the connecting rod 27. When the slump bucket 4 stops rotating, the operator starts the second cylinder 28, and the telescopic end of the second cylinder 28 drives the bearing 25 and the slump bucket 4 to move vertically upward through the connecting rod 27. When the slump bucket 4 is completely separated from the concrete inside, the second cylinder 28 is stopped from working, and the slump bucket 4 is rotated until it is opposite to the concrete on the tray 3. This design method enables the slump bucket 4 to be separated from the concrete smoothly, avoids the slump bucket 4 from colliding with the concrete during the separation process, and ensures the accuracy of the concrete slump.

[0020] like Figure 1 As shown, the base plate 1 is provided with a mounting plate 29 of the same height as the tray 3, the scale 9 is fixedly mounted on the top of the mounting plate 29, a second motor 30 is fixedly mounted on the top of the mounting plate 29, an output end of the second motor 30 is fixedly provided with a second vertically upward screw rod 31, the second screw rod 31 is parallel to the scale 9, and a second shaft sleeve 32 is threadedly sleeved on the second screw rod 31, the scraper 8 is fixedly mounted on the second shaft sleeve 32, a second slider 33 slidably sleeved on the scale 9 is fixedly mounted on the second shaft sleeve 32, a sliding groove 34 perpendicular to the scraper 8 is opened on the top of the base plate 1, a limit block 35 fixedly connected to the bottom of the mounting plate 29 is slidably provided in the sliding groove 34. When the slump bucket 4 is separated from the concrete rotation and relative, the operator starts the second motor 30, and the second motor 30 drives the second screw 31 to rotate through its output end, so that the second sleeve 32 drives the scraper 8 to move vertically on the second screw 31, and the second slider 33 slides vertically on the scale 9 with the second sleeve 32. When the bottom surface of the scraper 8 moves to be flush with the top surface of the concrete after collapse, the second motor 30 stops working. At this time, the operator pushes the mounting plate 29 to drive the scraper 8 to move and smooth the top surface of the concrete after collapse, and records the scale on the scale 9 at this time. The height of the slump bucket 4 is subtracted from the scale of the scale 9 after the concrete collapses, and the slump of the concrete can be obtained. In this process, the limit block 35 is slidably arranged in the slide 34. This design method is convenient for smoothly adjusting the horizontal height of the scraper 8, so that the scraper 8 can smooth the collapsed concrete evenly, which is convenient for accurately measuring the slump value of the concrete, and the structure is simple and the effect is good.

[0021] Working principle:

[0022] First, the operator places the slump bucket 4 on the tray 3 , and then uses two first cylinders 6 to make the two clamping blocks 7 relatively abut against the slump bucket 4 , and then pours concrete into the slump bucket 4 until the concrete is flush with the top of the slump bucket 4 .

[0023] Next, the operator starts the first motor 11. The output end of the first motor 11 drives the first gear 15, the tray 3 and the slump bucket 4 thereon to rotate through the first rotating shaft 12, so that the concrete in the slump bucket 4 rotates and levels. During this process, the two clamping blocks and the two connecting pieces rotate with the tray. The rotating first gear 15 drives the first screw rod 17 to rotate through the second gear 16 meshing with it, and then the first sleeve 19 drives the sleeve 23 and the knocking head 13 to slide vertically on the first screw rod 17, and the first slider 20 slides vertically on the limit rod 18 with the first sleeve 19 through the connecting piece 21.

[0024] During this process, the spring 24 in the sleeve 23 pushes the knocking head 13, so that the knocking head 13 continues to abut against the outer wall of the slump bucket 4. When the knocking head 13 moves vertically to the knocking groove 36, the spring 24 pushes the knocking head 13, so that the knocking head 13 abuts against the knocking groove 36 for knocking, and then the first sleeve 19 drives the knocking head 13 to slide vertically through the sleeve 23 and abut and move out of the knocking groove 36, thereby achieving the knocking of the slump bucket 4.

[0025] Furthermore, when the slump bucket 4 rotates, the inner wall of the bearing 25 fixed thereon rotates relative to the outer wall of the bearing 25 on the connecting rod 27 .

[0026] When the concrete in the slump bucket 4 rotates evenly, the first motor 11 stops working, and the operator starts the second cylinder 28. The telescopic end of the second cylinder 28 drives the bearing 25 and the slump bucket 4 to move vertically upward through the connecting rod 27. When the slump bucket 4 is completely separated from the concrete inside it, the second cylinder 28 stops working, and the slump bucket 4 is rotated until it is opposite to the concrete on the tray 3.

[0027] Next, the operator starts the second motor 30, and the second motor 30 drives the second screw 31 to rotate through its output end, so that the second sleeve 32 drives the scraper 8 to move vertically on the second screw 31, and the second slider 33 slides vertically on the scale 9 with the second sleeve 32. When the bottom surface of the scraper 8 moves to be flush with the top surface of the collapsed concrete, the second motor 30 stops working. At this time, the operator pushes the mounting plate 29 to drive the scraper 8 to move and smooth the top surface of the collapsed concrete, and records the scale on the scale 9 at this time. The height of the slump bucket 4 is subtracted from the scale of the scale 9 after the concrete collapses, and the slump of the concrete can be obtained. In this process, the limit block 35 is slidably arranged in the slide groove 34.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
