[0002] In the field of construction and engineering, the production and testing of concrete specimens is one of the important indicators for determining whether the mechanical properties of concrete are qualified or not. First of all, it is necessary to ensure that the quality of the specimens produced is representative of the batch of concrete. In order to ensure the quality of the concrete specimens, sufficient vibration must be carried out during production to eliminate bubbles inside the concrete and ensure its uniformity. Especially in recent years, the state has further standardized the quality of engineering projects, and the frequency of sampling of concrete strength specimens has also increased. They must be sampled and produced at the construction site. The traditional fixed concrete test block vibration platform is large in size, inconvenient to move, and cannot adapt to on-site specimen production.

[0003] The existing mobile vibration platform usually includes a vibration table mounted on a movable base, which is in contact with and supported by the ground through casters so that it can be moved and adjusted between workplaces. However, the casters and the ground are in point contact, which is very easy to be damaged when the vibration platform is working; in addition, the equipment is not stable enough during operation, and it is easy to shake and move while the exciting force is transmitted to the ground, which affects the quality of specimen production and the service life of the test mold, and even causes the risk of specimen falling off and personal injury.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Please refer to Figures 1 to 4 As shown, a mobile concrete test block vibration platform includes a table 100 and a control component 110. A test mold box 101 is arranged on the top of the table 100, and the test mold box 101 is used to contain concrete. A vibration device 103, a moving component 130 and two elastic components 150 are arranged at the bottom of the table 100. The two elastic components 150 are respectively arranged on opposite sides of the table 100, and a support seat 105 is detachably arranged below the elastic component 150. The sum of the height of the elastic component 150 in a compressed state and the height of the support seat 105 is greater than the height of the moving component 130, and the height of the elastic component 150 in an extended state is less than the height of the moving component 130.

[0025] The control component 110, the vibration device 103 and the external power supply form a passage, and the control component 110 is used to control the opening and closing of the vibration device 103. The control component 110 is an existing PLC controller, and the staff can control the running time of the vibration device 103 through the control component 110 according to the production requirements of the test piece. Preferably, an existing leakage protection device can also be installed in the passage to ensure the personal safety of the staff. The vibration device 103 is an existing high-frequency vibrator.

[0026] The moving assembly 130 includes a plurality of casters 131 , which are shock-absorbing rubber wheels. The plurality of casters 131 are installed at intervals at the bottom of the table top 100 and are rotatably connected to the bottom of the table top 100 .

[0027] When the staff uses the concrete test block vibration platform, they need to first move the concrete test block vibration platform to the construction site, then lift the vibration platform by manpower, place the support seat 105 under the elastic component 150, so that the top of the support seat 105 abuts against the bottom of the elastic component group 150, thereby separating the moving component 130 from the ground. Since the contact area between the support seat 105 and the ground is large, the contact between the concrete test block vibration platform and the ground is more stable. After the concrete test block vibration platform is installed, the staff can control the vibration device 103 to operate through the control component 110, so that the table 100 vibrates on the elastic component 150, thereby making a concrete specimen.

[0028] Specifically, the elastic component 150 includes a first fixing plate 151, an elastic member 153 and a second fixing plate 155, and the first fixing plate 151 and the second fixing plate 155 are fixedly mounted on both sides of the elastic member 153, respectively. The first fixing plate 151 or the second fixing plate 155 is screwed or welded to the bottom of the table 100 on one side away from the elastic member 153. The elastic member 153 is an existing compression spring. The elastic component 150 can provide a vibration space for the table 100; the elastic component 150 can also provide a push-pull force to the table 100, so as to better vibrate the concrete and improve the quality of the specimen.

[0029] Specifically, the support seat 105 is a rectangular parallelepiped structure, and a groove is provided on the top thereof for placing the first fixing plate 151 or the second fixing plate 155. The support seat 105 can be made of alloy or wood. Preferably, the length and width of the groove are adapted to the length and width of the first fixing plate 151 or the second fixing plate 155, so as to limit the first fixing plate 151 or the second fixing plate 155, so as to prevent the table 100 from being displaced when the vibration device 103 is in operation.

[0030] Preferably, a handle 107 is provided on one side of the table 100, and the control assembly 110 is installed at one end of the handle 107 away from the table 100. By installing the handle 107, it is convenient for the staff to move the concrete test block vibration platform. In addition, when raising the concrete test block vibration platform, the moving assembly 130 or the support seat 105 can also be used as a support point, and one side of the table 100 can be raised by pulling or pressing down the handle 107, so that the staff can place the concrete test block vibration platform on the support seat 105.

[0031] Preferably, a lifting assembly 170 is provided on one side of the table top 100 where the elastic assembly 150 is provided. The lifting assembly 170 can move along the height direction of the table top 100. When the lower end of the lifting assembly 170 contacts the ground, the moving assembly 130 is separated from the ground.

[0032] Specifically, the lifting assembly 170 includes a turntable 171, a screw 173 and a top sleeve 175. The turntable 171 is fixedly connected to the top of the screw 173, and the screw 173 is screwed to the table 100. The bottom end of the screw 173 is rotatably connected to the top sleeve 175 through a bearing, specifically, the bearing is embedded in the top sleeve 175 and is rotatably connected to the top sleeve 175. One end of the screw 173 away from the turntable 171 is interference-connected with the inner hole of the bearing. When lifting the table 100, the staff can also directly rotate the turntable 171 to move the screw 173 downward until the lower end of the top sleeve 175 contacts the ground and separates the moving assembly 130 from the ground. At this time, the staff can place the support seat 105 below the elastic member group 150. The staff rotates the turntable 171 in the opposite direction so that the lower end of the top sleeve 175 is separated from the ground, and the lifting work of the table 100 can be completed.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
