Technical Field
[0001] The utility model relates to the technical field of concrete, in particular to a vibration table for concrete testing. Background Art
[0002] Concrete is a general term for engineering composite materials that are bonded together by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, mixed with water in a certain proportion and obtained by mixing. It is also called ordinary concrete. It has the characteristics of abundant raw materials, low price and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability and a wide range of strength grades. These characteristics make its scope of use very wide. It is not only used in various civil engineering projects, but also in shipbuilding, machinery industry, ocean development, geothermal engineering, etc.
[0003] When testing concrete, a vibration table is used to simulate the various environments that concrete encounters during its manufacturing, assembly, transportation, and use. This is used to test whether the concrete can withstand environmental vibrations and transmit them to the vibration plate. The concrete on its surface is vibrated to obtain certain experimental conclusions and to better summarize and improve the product. However, the existing vibration table is relatively large in size, which makes it inconvenient to move flexibly while moving and to remain stably fixed during vibration tests. For this reason, we have proposed a vibration table for concrete testing. Utility Model Content
[0004] In order to overcome the deficiencies of the prior art, the utility model provides a vibration table for concrete testing, which enables the vibration table to move flexibly while being moved and also to remain stably fixed during the vibration test.
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a vibration table for concrete testing, comprising a concrete testing vibration table and a vibration table base, wherein moving wheels are arranged at the four corners of the vibration table base, a bidirectional screw rod is movably connected in the vibration table base, both ends of the bidirectional screw rod are threadedly connected with moving plates, the lower sides of two groups of moving plates are movably connected with connecting plates, the lower ends of the two groups of connecting plates are movably connected with contact plates, and both sides of the vibration table base are provided with limit grooves for limiting the movement of the moving plates;
[0006] By rotating the bidirectional lead screw, the moving plates are connected with the bidirectional lead screw through threads. Under the restriction of the limit groove, the moving plates approach each other and push the contact plate to move downward to contact the ground.
[0007] As a preferred technical solution of the utility model, both ends of the movable plate are sleeved in the limiting groove and abut against the inner wall surface of the limiting groove.
[0008] As a preferred technical solution of the utility model, one end of the bidirectional screw rod passes through the vibration table base and is connected to a turning handle.
[0009] As a preferred technical solution of the utility model, the surface of the handle is rounded, and the diameter of one end of the handle is larger than the diameter of the other end of the handle.
[0010] As a preferred technical solution of the utility model, an anti-skid pad is provided on the lower side of the contact plate, and the cross-sectional area of the anti-skid pad is equal to that of the contact plate.
[0011] As a preferred technical solution of the utility model, the width of the vibration table base is equal to the length of the movable plate, and the length of the connecting plate is less than the length of the movable plate.
[0012] Compared with the prior art, the utility model can achieve the following beneficial effects:
[0013] 1. In the utility model, when the concrete test vibration table is moved, it is moved by the moving wheels arranged on the vibration table base below the concrete test vibration table. After it moves to the fixed point, the bidirectional screw is rotated, and the moving plate is connected with the bidirectional screw by thread. Under the restriction of the limiting groove, the moving plates approach each other and push the contact plate to move downward and contact the ground, thereby increasing the contact area with the ground, limiting the moving wheels, avoiding the moving wheels from moving during use, fixing the concrete test vibration table, and improving the stability of the concrete test vibration table.
[0014] 2. In the utility model, the turning handle is provided, which makes it convenient for the operator to turn the turning handle to drive the bidirectional screw rod to rotate, which is conducive to improving the convenience of adjustment. The surface of the turning handle is rounded, and the diameter of one end of the turning handle is larger than the diameter of the other end of the turning handle, which can improve the comfort of the operator holding the turning handle.
[0015] 3. In the utility model, the friction between the contact plate and the ground is increased by providing an anti-skid pad, so that the contact plate can better contact the ground to fix the concrete test vibration table. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.
[0022] Embodiment:
[0023] like Figure 1-4 As shown, the utility model provides a vibration table for concrete test, including a concrete test vibration table 1 and a vibration table base 2, wherein moving wheels 3 are arranged at the four corners of the vibration table base 2, a bidirectional screw rod 4 is movably connected in the vibration table base 2, and both ends of the bidirectional screw rod 4 are threadedly connected with moving plates 5, the lower sides of the two groups of moving plates 5 are movably connected with connecting plates 6, and the lower ends of the two groups of connecting plates 6 are movably connected with contact plates 7, and limiting grooves 8 for limiting the movement of the moving plates 5 are provided on both sides of the vibration table base 2. When the concrete test vibration table 1 is moved, the moving wheels 3 arranged on the vibration table base 2 below the concrete test vibration table 1 are moved, and after moving to a fixed point, the bidirectional screw rod 4 is rotated, and the moving plates 5 are threadedly connected with the bidirectional screw rod 4. Under the restriction of the limiting groove 8, the moving plates 5 approach each other and push the contact plates 7 to move downward and conflict with the ground, thereby increasing the contact area with the ground, limiting the moving wheels 3, and preventing the moving wheels 3 from moving during use, so that the concrete test vibration table 1 is fixed, and the stability of the concrete test vibration table 1 is improved.
[0024] The two ends of the movable plate 5 are sleeved in the limiting groove 8 and contact the inner wall surface of the limiting groove 8, so that the two ends of the movable plate 5 can be better limited by the limiting groove 8, which is beneficial to improve the effect of the two groups of movable plates 5 being threadedly connected with the bidirectional screw rod 4. As the bidirectional screw rod 4 rotates, they can move closer to each other more stably.
[0025] One end of the bidirectional screw rod 4 passes through the vibration table base 2 and is connected to a turning handle 9. The setting of the turning handle 9 facilitates the operator to turn the turning handle 9 to drive the bidirectional screw rod 4 to rotate, which is beneficial to improving the convenience of adjustment. The surface of the turning handle 9 is rounded, and the diameter of one end of the turning handle 9 is larger than the diameter of the other end of the turning handle 9, thereby improving the comfort of the operator holding the turning handle 9.
[0026] An anti-skid pad 10 is provided on the lower side of the contact plate 7. The cross-sectional area of the anti-skid pad 10 is equal to that of the contact plate 7. The anti-skid pad 10 increases the friction between the contact plate 7 and the ground, so that the contact plate 7 can better contact the ground to fix the concrete test vibration table 1.
[0027] The width of the vibration table base 2 is equal to the length of the movable plate 5 , so that the movable plate 5 can be better limited by the vibration table base 2 . The length of the connecting plate 6 is less than that of the movable plate 5 , which improves the flexibility of the connecting plate 6 in the vibration table base 2 .
[0028] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
