Description

Technical Field

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

[0002] The cement concrete slump test is a method used to evaluate the workability of fresh concrete. This test primarily measures the fluidity or consistency of concrete. The slump cone is cleaned inside and out and placed on a rigid base that has been pre-moistened with water, ensuring the base is flat and does not absorb water. The cone is then placed on the bottom of a tamping mechanism, and cement is placed in the cone. The tamping mechanism then tamps the cement in the slump cone.

[0003] At present, when traditional detection devices are used to test the slump of cement, the force applied to the cement tamping mechanism during the tamping process is relatively large, which can easily cause the slump barrel to be affected by the cement inside it, causing it to shake left and right or cause cement to leak out of the slump barrel, thereby affecting the accuracy of subsequent cement slump detection.

DETAILED DESCRIPTION

[0018] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0019] The following describes the cement concrete slump detection device according to the embodiment of the present invention in conjunction with the accompanying drawings.

[0020] like Figure 1-Figure 2 As shown, the cement concrete slump detection device of the embodiment of the present utility model may include a base plate 1, a mounting frame 2, a pounding mechanism 3, a collapse mechanism 4, two driving mechanisms 5 and two pressing mechanisms 6.

[0021] The mounting frame 2 is vertically mounted on the base plate 1, and the ramming mechanism 3 is mounted on the top of the mounting frame 2. It should be noted that the mounting frame 2 may include a vertically mounted column 21 and a top plate 22 arranged on the vertical frame.

[0022] The collapse mechanism 4 is mounted on the base plate 1 and may include a collapse bucket 41 and two first serrations 42. The collapse bucket comprises an inverted trapezoidal upper portion and a trapezoidal lower portion. Two mounting slots 411 are disposed on opposite sides of the upper portion of the collapse bucket 41. The two first serrations 42 are mounted opposite each other on the lower portion of the collapse bucket 41.

[0023] It should be noted that the two pressing mechanisms 6 are installed on both sides of the pounding mechanism 3 , and the two pressing mechanisms 6 are respectively engaged with the collapse bucket 41 through the first serrations 42 , thereby ensuring the stability of the collapse bucket 41 .

[0024] The two driving mechanisms 5 are respectively mounted on two sides of the mounting frame 2 .

[0025] It can be understood that the two driving mechanisms 5 are respectively connected to the two pressed arc plates 61 , and the pressed arc plates 61 can be driven by the driving mechanisms 5 to rotate around the base plate 1 .

[0026] Specifically, when personnel need to test the slump of cement concrete, they first use the driving mechanism 5 to place the pressing mechanism 6 on the surface of the slump bucket 41, and engage with the surface of the slump bucket 41. Then, cement concrete is poured into the slump bucket 41, and the driving motor 31 is started, which drives the pressing plate 34 to move up and down to compact the cement concrete.

[0027] After a period of time, the pressing arc plate 61 is pulled by the driving mechanism 5 and the side of the pressing arc plate 61 is made perpendicular to the bottom plate 1. The current height of the cement concrete is obtained by the scale 7 feet, and it is compared with the gap between the upper and lower parts of the collapse barrel 41 to obtain the collapse measure of the cement concrete.

[0028] In one embodiment of the present invention, Figure 1 As shown, the pounding mechanism 3 may include a driving motor 31 , a connecting rod 32 , a transverse plate 33 , a pressing plate 34 and two engaging columns 35 .

[0029] The driving motor 31 is mounted on the top of the mounting frame 2 , the connecting rod 32 is connected to the output shaft of the driving motor 31 , and the transverse plate 33 is mounted on the connecting rod 32 .

[0030] It should be noted that the driving motor 31 described in this embodiment can be a push rod motor or a hydraulic cylinder. At the same time, the push rod of the driving motor 31 performs reciprocating motion to drive the cross plate 33 to tamp the inside of the collapse mechanism 4 to compact the concrete.

[0031] Two engaging posts 35 are respectively mounted on the two ends of the transverse plate 33 . A through opening 351 is formed on the engaging posts 35 . The pressing plate 34 is mounted on the bottom end of the connecting rod 32 .

[0032] It can be understood that during the tamping process, the locking column 35 will move downward and fit into the matching groove 611. Since the pressing arc plate 61 and the collapse bucket 41 are engaged with each other, during the matching process, the collapse bucket 41 can be fixed more stably through the engagement relationship between the pressing arc plate 61 and the first serration 42.

[0033] In one embodiment of the present invention, Figure 1 As shown, the driving mechanism 5 may include a rotating wheel 51 , a belt 52 and a rotating motor 53 .

[0034] Among them, the two rotating wheels 51 are respectively installed on both sides of the mounting frame 2, and the two rotating motors 53 are also respectively installed inside the two sides of the mounting frame 2. The output shaft of the rotating motor 53 is connected to the rotating shaft in the middle of the rotating wheel 51, and one end of the belt 52 is installed on the rotating wheel 51.

[0035] It should be noted that the rotating electricity described in this embodiment can drive the rotating wheel 51 installed on the column 21 to rotate, one end of the belt 52 is installed on the rotating wheel 51, and the other end of the belt 52 is connected to the connecting frame 66. Through the rotation of the belt 52, the pressed arc plate 61 can be pulled so that the pressed arc plate 61 is close to the column 21, thereby releasing the meshing relationship between the first serration 42 and the pressed arc plate 61.

[0036] In one embodiment of the present invention, Figure 1 As shown, the pressing mechanism 6 may include a pressing arc plate 61 , a support rod 62 , a support plate 63 , a spring 64 , a second serration 65 and a connecting frame 66 .

[0037] The two support rods 62 are rotatably mounted on the bottom plate 1 , respectively. The pressed arc plate 61 is mounted on the support rods 62 . A matching groove 611 is formed on the top of the pressed arc plate 61 .

[0038] It should be noted that the matching groove 611 described in this embodiment facilitates the engagement of the locking column 35. External bolts are passed sequentially through the through-hole 351 and the mounting groove 411 to secure the slump bucket 41. Subsequently, the drive motor 31 drives the pressure plate 34 upward, thereby driving the bolted slump bucket 41 upward. It should be noted that in this state, the pressure plate 61 is away from the slump bucket 41.

[0039] The support plate 63 is provided on one side of the support rod 62 , and the spring 64 is provided between the support plate 63 and the bottom plate 1 . One end of the spring 64 is installed at the bottom of the support plate 63 , and the other end of the spring 64 is installed on the bottom plate 1 .

[0040] It can be understood that the spring 64 can abut the pressing arc plate 61 so that the pressing arc plate 61 and the collapse bucket 41 are close to each other.

[0041] The connecting frame 66 is installed on the pressed arc plate 61, and the connecting frame 66 is connected to the belt 52 of the driving mechanism 5 arranged on the same side thereof. The second serration 65 is arranged inside the pressed arc plate 61, and the surface of at least one pressed arc plate 61 is provided with a scale of 7 feet.

[0042] It should be noted that the driving mechanism 5 described in this embodiment can shorten the distance of the belt 52 and drive the connecting frame 66 connected to the belt 52 away from the slump bucket 41 .

[0043] In summary, the cement concrete slump detection device of the embodiment of the present invention can avoid the shaking and cement leakage of the slump bucket 41 caused by uneven force by fixing the outside of the slump bucket 41, thereby ensuring the subsequent accurate detection of cement slump.
