Description

Technical Field

[0001] The present application relates to the technical field of concrete processing, and in particular to a concrete slump detection device. Background Art

[0002] Concrete is the most commonly used material in civil engineering, used for casting, forming, and setting various components. After concrete is prepared, a slump test is performed to measure its fluidity. The greater the slump, the better the concrete's fluidity. This slump test uses a trumpet-shaped slump bucket. First, concrete is poured into the bucket and compacted. The top of the bucket is then smoothed to ensure that the concrete level is level with the top of the bucket. The bucket is then lifted vertically upward, causing the concrete to slump. The vertical distance from the top of the slump bucket to the highest point of the collapsed concrete is the concrete slump.

In addition, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the internal parts of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.

[0037] like Figure 1-Figure 4As shown, a concrete slump detection device includes a base 10, a slump cone 11, a support rod 21, a telescopic member 22, a rotating frame 23, a tape measure 24, a scraper 25 and a lifting member; the base 10 is horizontally placed on the working surface; the slump cone 11 is vertically placed on the top surface of the base 10; two support rods 21 are arranged on both sides of the slump cone 11, one end of which abuts against the outer wall of the slump cone 11, and the other end extends horizontally to a side away from the slump cone 11; the telescopic member 22 is vertically placed beside the slump cone 11; the rotating frame 23 is vertically placed on the side of the slump cone 11; the scraper 25 ... The movable frame 23 is horizontally rotated and arranged at the top of the telescopic member 22, and a first sliding hole 231 is opened downwardly along the length direction of the top of the rotating frame 23; the tape measure 24 is slidably arranged in the cavity of the first sliding hole 231; the scraper 25 is slidably arranged on the rotating frame 23, and is located beside the sliding path of the tape measure 24, and the scraping blade height of the scraper 25 is consistent with the height of the barrel mouth of the collapse cone 11; the lifting assembly is vertically fixed on the base 10, and is fixedly connected to the end of the support rod 21 away from the collapse cone 11.

[0038] In the above scheme, the base 10 is placed horizontally to ensure that the entire device does not tilt during use, thereby ensuring accurate slump measurement. The slump cone 11 is placed vertically on the top surface of the base 10, providing a standardized container for concrete samples. The provision of a support rod 21 enhances the stability of the slump cone 11, preventing shaking during the pouring or removal of concrete. One end of the support rod 21 abuts the outer wall of the slump cone 11, while the other end extends horizontally, forming a stable support frame, reducing human error and improving the accuracy of slump measurement. The telescopic member 22 adjusts the height of the rotating frame 23 to meet different operating requirements. The rotating frame 23 can rotate horizontally, facilitating operator observation and recording. The measuring tape 24 slides through the first sliding hole 231, conveniently measuring the slump height of the concrete. A scraper 25 is positioned adjacent to the measuring tape 24, with its scraping blade aligned with the opening of the slump cone 11. This ensures that the concrete shape is not affected during slump measurement and helps clear excess concrete from the opening of the slump cone 11. The lifting assembly is fixed to the base 10 and connected to the support rod 21. By raising or lowering the support rod 21, the bottom of the collapse cone 11 is moved closer to or farther from the base 10, providing additional stability and support for the entire device.

[0039] In practice, the contact portion between the slump cone 11 and the support rod 21 in this application is provided with an annular hanging ear 111. The end of the support rod 21 adjacent to the slump cone 11 is provided with a protrusion 211, the circumference of the protrusion 211 being in contact with the inner wall of the hanging ear 111. The provision of the hanging ear 111 not only improves the overall modal strength of the slump cone, but also facilitates a stable connection with the support rod 21. The provision of the protrusion 211 not only enhances the structural strength of the support rod 21, but also ensures that the support rod 21 stably lifts the slump cone 21.

[0040] A second sliding hole 101 is provided at the top of the base 10 along its length direction, and the hole length direction of the second sliding hole 101 is coplanar with the rod length direction of the support rod 21; a groove 102 is provided at the bottom of the base 10, and the groove width direction of the groove 102 is consistent with the length direction of the base 10, and the notch of the groove 102 is facing the side of the base 10 close to the telescopic part 22.

[0041] In the above solution, the provision of second sliding hole 101 ensures a stable connection between the lifting assembly and support rod 21. The length of second sliding hole 101 is coplanar with the length of support rod 21, preventing deflection of support rod 21 when the lifting assembly moves it. The provision of groove 102 optimizes the spatial structure of base 10, effectively distributing the weight of base 10 and improving the overall load-bearing capacity.

[0042] The lifting assembly includes a fixed frame 30, a column 31, a slider 32, a connecting rod 33, a connecting block 34, a support rod 35 and a pull rod 36; the two U-shaped fixed frames 30 are buckled on the base 10 and symmetrically arranged on both sides of the collapse cone 11 along the length direction of the support rod 21; the two columns 31 are fixedly arranged in the middle of each of the fixed frames 30; the slider 32 is slidably arranged in the cavity of the second sliding hole 101, and the slider 32 is fixedly connected to the end of the support rod 21 away from the collapse cone 11 on one side of the collapse cone 11; the two connecting rods 33 are arranged directly below each of the support rods 21, and one end of each of the connecting rods is connected to the support rod The lower end face of the support rod 21 is fixedly connected, and the other end thereof extends toward the side close to the base 10; the two connecting blocks 34 are slidably placed on the base 10, and the top of the connecting block 34 is fixedly connected to one end of each connecting rod 33 away from each support rod 21; the two support rods 35 are arranged in the groove 102, and one end of each support rod 35 is fixedly connected to the bottom of each connecting block 34, and the other end thereof extends toward the bottom of the groove 102; the pull rod 36 is slidably arranged in the groove 102, and one end of the pull rod 36 passes through the bottom of the groove 102, and the other end thereof is hinged to one end of the two support rods 35 away from the connecting block 34.

[0043] In the above scheme, two U-shaped fixing frames 30 are buckled onto the base 10 and symmetrically arranged on both sides of the collapse cone 11 along the length direction of the support rod 21. This design enhances the overall stability of the lifting assembly, making it less likely to shake or tilt during operation. The column 31 is fixedly arranged in the middle of each fixing frame 30, providing stable support for the sliding of the slider 32. The slider 32 is slidably arranged in the cavity of the second sliding hole 101 and is fixedly connected to the end of the support rod 21 away from the collapse cone 11. This design allows the support rod 21 and the collapse cone 11 to move up and down with the sliding of the slider 32, realizing a flexible lifting function. The design of the connecting rod 33 and the connecting block 34 forms a stable connection between the lower end face of the support rod 21 and the base 10, while allowing the support rod 21 to move freely in the vertical direction. The pull rod 36 is slidably disposed within the groove 102, with one end extending through the bottom of the groove 102 and the other end hinged to the ends of the two support rods 35 away from the connecting block 34. This design allows the user to adjust the height of the support rod 21 by pulling the pull rod 36, which is easy and labor-saving. The support rod 35 is disposed within the groove 102 and connected to the connecting block 34 and the pull rod 36. This layout not only saves space but also makes the adjustment process smoother.

[0044] The rotating frame 23 has a third sliding groove 232 formed on one side of the sliding path of the tape measure 24 along its length, and the end of the scraper 25 away from the scraping edge is fixed in the third sliding groove 232.

[0045] In the above embodiment, the end of the scraper 25 away from the scraping blade is fixedly disposed within the third chute 232. This arrangement ensures the stability of the scraper 25 during sliding, preventing inaccurate leveling caused by shaking or deviation. The user can adjust the relative position of the scraping blade and the mouth of the slump cone 11 by moving the scraper 25 within the third chute 232 as needed to accommodate slump cones 11 of different heights or concrete layers of varying thicknesses.

[0046] A slide plate 26 is provided between the measuring tape 24 and the inner wall of the first sliding hole 231 . The inner side surface of the slide plate 26 is fixedly connected to the outer side surface of the measuring tape 24 , and the outer side surface thereof is slidably connected to the inner wall of the first sliding hole 231 .

[0047] In the above arrangement, the inner surface of the slide 26 is fixedly connected to the outer surface of the measuring tape 24, while the outer surface is slidably connected to the inner wall of the first sliding hole 231. This arrangement ensures the stability of the measuring tape 24 during sliding, preventing inaccurate measurements caused by shaking or deviation. Acting as an intermediary between the measuring tape 24 and the inner wall of the first sliding hole 231, the slide 26 effectively reduces direct contact between the measuring tape 24 and the inner wall of the first sliding hole 231, thereby reducing friction and wear. This not only extends the service life of the measuring tape 24 and the first sliding hole 231, but also maintains a smooth sliding process.

[0048] A pull ring 37 is provided at one end of the pull rod 36 away from the groove 102 . The pull ring 37 is in a C-shaped structure as a whole, and the outer side surfaces of the pull rod 36 at both ends are hinged.

[0049] In the above solution, the C-shaped structure provides ample grip space, allowing the user to apply force steadily during operation, avoiding operational errors caused by an unstable grip. The ends of the pull ring 37 are hinged to the outer side of the pull rod 36. This connection is not only secure and reliable, but also capable of withstanding significant tension. Even when encountering significant resistance or load during use, the pull ring 37 maintains a stable connection and will not fall off or become damaged due to excessive force.

[0050] The working principle of the concrete slump detection device of the present application is as follows: the slump cone 11 is placed on the base 10, the lug 111 is abutted against the protrusion 211, and then concrete is poured into the slump cone 11 in three batches. The concrete is stirred with a tamping rod to eliminate bubbles. After the concrete is filled, the top concrete is scraped flat with a scraper 25 to make it flush with the top of the slump cone 11. The pull rod 36 is then pulled to move the support rod 35 in the direction away from the connecting block 34. Since the two ends of the connecting block 34 are respectively connected to the connecting rod 33 and the support rod 35, the support rod 35 moves with the movement of the support rod 35, driving the connecting block 34 to move in the direction of the collapse cone 11. Since the two ends of the connecting rod 33 are respectively rotatably connected to the connecting block 34 and the support rod 21, the connecting rod 33 moves with the movement of the connecting block 34, driving the support rod 21 to move upward, and the protrusion 211 moves upward accordingly, driving the hanging ear 111 and the collapse cone 11 to move upward, so that the collapse cone 11 is separated from the concrete, and the concrete collapses. The highest point of the collapsed concrete is found, the rotating frame 23 is rotated so that the rotating frame 23 is located above this point, and the slide plate 26 is pushed to move in the first sliding hole 231, and the tape measure 24 moves accordingly. The tape measure 24 is moved to just above the highest point of the concrete, and the tape of the tape measure 24 is pulled to measure. At this time, the distance from the tape measure 24 to the highest point of the collapsed concrete is the collapse height.

[0052] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents.
