[0030] refer to Figures 1 to 3 A concrete vibration table fixing device according to an embodiment of the present invention is described.

[0031] like Figures 1 to 3 As shown, the concrete vibrating table fixing device includes a fixing assembly 100, which is used to be fixedly connected to the concrete vibrating table 10; a mobile frame 200, which is horizontally arranged on the fixing assembly 100 and is slidably connected to the fixing assembly 100 in a vertical direction; two first limiting assemblies 300, which are horizontally arranged on the mobile frame 200 and are arranged opposite to each other, and the extension direction of the two first limiting assemblies 300 is perpendicular to the extension direction of the mobile frame 200; and a plurality of second limiting assemblies 400, Several second limiting assemblies 400 are horizontally arranged on the mobile frame 200, and several second limiting assemblies 400 are located between two first limiting assemblies 300. The extension direction of several second limiting assemblies 400 is perpendicular to the extension direction of the mobile frame 200. Each second limiting assembly 400 is slidably connected to the mobile frame 200, and each second limiting assembly 400 can slide along the extension direction of the mobile frame 200; several first limiting assemblies 300, several second limiting assemblies 400 and the mobile frame 200 are enclosed to form several limiting frames, which are used to limit the position of the concrete specimens.

[0032] like Figure 1As shown, the movable frame 200 is two rods 210 extending in the left and right directions, the two rods 210 are parallel to each other and arranged oppositely, the first limit assembly 300 and the second limit assembly 400 extend in the front and rear directions, and several second limit assemblies 400 are located between the two first limit assemblies 300, wherein the front and rear ends of the first limit assembly 300 are respectively fixed on the two oppositely arranged rods 210, and the front and rear ends of the second limit assembly 400 are respectively arranged on the two oppositely arranged rods 210, and the second limit assembly 400 is slidably connected to the rods 210, each second limit assembly 400 can slide in the left and right directions, and the two rods 210 can move in the vertical direction at the same time to drive the first limit assembly 300 and the second limit assembly 400 to move in the vertical direction. Therefore, by flexibly adjusting the height of the mobile frame 200 and the position of the second limiting assembly 400 on the mobile frame 200, the first limiting assembly 300, the second limiting assembly 400 and the mobile frame 200 are combined to form a number of limiting frames that can limit concrete specimens, which are suitable for concrete specimen molds of different sizes, shapes and types, ensuring that molds of various shapes can be relatively fixed during the vibration compaction process, thereby reducing vibration power loss.

[0033] In some specific embodiments of the present invention, the first limiting assembly 300 includes: a first cross bar 310, the first cross bar 310 is fixedly set on the movable frame 200, and the first cross bar 310 and the movable frame 200 are perpendicular to each other; a plurality of first sliding cards 320, and the plurality of first sliding cards 320 are evenly arranged on the first cross bar 310 along the axial direction, and each first sliding card 320 can slide along the extension direction of the first cross bar 310.

[0034] like Figure 1 and Figure 2 As shown, the first crossbar 310 is arranged along the front-to-back direction, and the two ends of the first crossbar 310 are respectively fixedly arranged on two oppositely arranged rods 210. The two first crossbars 310 and the two rods 210 enclose a rectangular shape. Each first crossbar 310 is provided with a plurality of first sliding cards 320 along the axis. The first sliding cards 320 extend in the left-right direction. In this specific embodiment, the first sliding cards 320 are located at one end of the first crossbar 310 near the second crossbar 410, that is, the first sliding card 320 on the left first crossbar 310 extends to the right, and the first sliding card 320 on the right first crossbar 310 extends to the left. All the first sliding cards 320 are located on the same horizontal plane. Each first sliding card 320 can slide freely on the first crossbar 310 independently and can be synchronously raised and lowered in the vertical direction under the action of the movable frame 200.

[0035] In some specific embodiments of the present invention, the cross section of the first cross bar 310 is square, so that the first cross bar 310 fits the mold and enhances its fixing effect.

[0036] In some specific embodiments of the present invention, the second limiting assembly 400 includes: a second cross bar 410, the second cross bar 410 is slidably set on the movable frame 200, and the second cross bar 410 and the movable frame 200 are perpendicular to each other; a plurality of second sliding cards 420, and the plurality of second sliding cards 420 are evenly arranged on the second cross bar 410 along the axial direction, and each second sliding card 420 can slide along the extension direction of the second cross bar 410.

[0037] like Figure 1 and Figure 2 As shown, the second crossbar 410 is arranged along the front-to-back direction, with its ends movably mounted on two opposing rods 210. All second crossbars 410 are located between the two first crossbars 310, and each second crossbar 410 extends in the same direction as the first crossbar 310. Each second crossbar 410 is provided with a plurality of second sliding clips 420 along its axis. The second sliding clips 420 extend in the left-right direction, with their ends extending toward either side of the second crossbar 410. In this embodiment, the second crossbar 410 is located on the centerline of the corresponding second sliding clip 420. All second sliding clips 420 are located on the same horizontal plane as the first sliding clip 320. Each second crossbar 410 can slide freely on the movable frame 200 independently. Each second sliding clip 420 can slide freely on the second crossbar 410 independently. Under the control of the movable frame 200, the second crossbar 410 and the second sliding clips 420 mounted thereon can be synchronously raised and lowered in the vertical direction.

[0038] Thus, the positions of the first sliding card 320, the second cross bar 410 and the second sliding card 420 are adjusted according to the sizes and quantities of different molds, so that a plurality of rectangular limit frames are formed between the first cross bar 310, the first sliding card 320, the second cross bar 410, the second sliding card 420 and the movable frame 200, thereby limiting concrete molds of any shape, so that the concrete specimens can be relatively fixed during the vibration compaction process to reduce the vibration power loss and ensure the molding quality of the concrete specimens.

[0039] It should be noted that the first sliding card 320 is fixed and slided on the first cross bar 310 through a bolt structure. Similarly, the second sliding card 420 is fixed and slided on the second cross bar 410 through a bolt structure, and the second cross bar 410 is fixed and slided on the movable frame 200 through a bolt structure. The number of first sliding cards 320 on each first cross bar 310 and the number of second sliding cards 420 on each second cross bar 410 are the same to ensure that the first sliding cards 320 can correspond one-to-one with the second sliding cards 420 to form a rectangular limiting frame.

[0040] In some specific embodiments of the present invention, the cross section of the second cross bar 410 is square, so that the second cross bar 410 fits the mold and enhances its fixing effect.

[0041] In some specific embodiments of the present invention, the fixing assembly 100 includes four fixing supports 110 , and the four fixing supports 110 are all connected to the moving frame 200 .

[0042] In some specific embodiments of the present invention, the fixed support 110 includes a fixing portion 111 and a connecting portion 112. The connecting portion 112 is arranged at the upper end of the fixing portion 111. The connecting portion 112 extends in the vertical direction. The movable frame 200 is slidably mounted on the connecting portion 112. The fixing portion 111 is used for detachable connection with the concrete vibration table 10.

[0043] like Figure 1 and Figure 3 As shown, the four fixed supports 110 are located at the four corners of the rectangle, the two ends of the rod 210 are connected to the two fixed supports 110, and the two rods 210 are located on opposite sides of the rectangle where the four fixed supports 110 are located. The two first cross bars 310 are located on the other opposite sides of the rectangle where the four fixed supports 110 are located. The connecting portion 112 is located at the upper end of the fixing portion 111 and extends upward in the vertical direction. Specifically, the connecting portion 112 is a round rod, and the left and right ends of the rod 210 are provided with circular collars. The circular collars correspond to the round rod and can be mounted on the round rod. The lifting and fixing of the movable frame 200 are achieved by a bolt structure.

[0044] Specifically, if Figure 3 As shown, the fixing portion 111 is a bolt structure, and the fixing support 110 is fixed to the table surface of the concrete vibration table 10 by the bolt structure. When use is completed, the bolt structure can be loosened to remove the entire device from the table surface, thereby making it easier to clean up the concrete dropped during the vibration process.

[0045] In some specific embodiments of the present invention, the movable frame 200 is slid according to the height of the concrete mold so that the height of the movable frame 200, the first limiting assembly 300 and the second limiting assembly 400 are slightly lower than the top of the concrete mold, and the first sliding card 320, the second crossbeam and the second sliding card 420 are moved to form a rectangular limiting frame to confine the corners of the concrete mold, thereby limiting the displacement of the concrete mold during the vibration process, wherein the first sliding card 320, the second crossbeam and the second sliding card 420 are all fixed by locking with a bolt structure, thereby achieving corresponding adjustments according to different test mold sizes to enhance the flexibility of the device.

[0046] It should be noted that when the number of concrete molds is small, the unused second crossbar 410 , first sliding card 320 and second sliding card 420 can be moved to the edge where they will not be used.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
