DETAILED DESCRIPTION
[0027] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0028] See also Figure 1 and Figure 2 This concrete vibration test bench is in the shape of a long strip, and its length is greater than the length of the concrete slab to be tested. The concrete slab can be mounted on a roller frame 3, and the roller frame 3 provides assistance for the movement of the concrete slab. After the concrete slab is moved into place, the roller frame 3 swings and the upper end sinks, so that the concrete slab is placed on the vibration table 2. The vibration table 2 is composed of an upper plate 5 and a positioning seat 6, which are elastically connected by a spring 9 sleeved between an upper sleeve 7 and a lower sleeve 8. When the vibration motor 4 is working, it can drive the upper plate 5 to vibrate at a certain frequency, and the spring 9 provides a reset force to achieve vibration testing.
[0029] join Figure 2 The vibration motor 4 is installed on both sides of the lower end of the upper plate 5 in a symmetrical installation manner, which can stably provide vibration amplitude and frequency.
[0030] The upper sleeve 7 and the lower sleeve 8 are also mounted on the four corners of the upper plate 5 and the positioning seat 6 respectively, and can provide stable elastic support.
[0031] See also Figure 3 The four corners of the upper plate 5 are fixed with support blocks 10 by bolts. The support blocks 10 are used to support the bottom of the concrete slab. The limit stop strips 11 serve to block the side walls of the concrete slab to prevent the concrete slab from slipping.
[0032] join Figure 4There are swing arms 13 on both sides of the roller frame 3, and the swing arms 13 are movably connected to the swing arm bracket 14 installed on the bracket 1. There is a push plate 15 connected to the push plate cylinder 16 in the middle of the swing arm 13. When the push plate cylinder 16 is working, the telescopic rod of the push plate cylinder 16 pushes outward to push the push plate 15, so that the swing arm 13 rotates on the swing arm bracket 14, driving the roller 12 at the upper end of the swing arm 13 to perform a lifting operation. After the roller 12 rises, the concrete slab can be lifted up to facilitate the rolling and removal of the concrete slab.
[0033] The plurality of swing arms 13 are connected by a push rod 17 to achieve synchronous rotation of all the swing arms 13 .
[0034] The rear end of the push plate cylinder 16 can rotate on the cylinder bracket 18, and when the push plate cylinder 16 pushes the push plate 15, an angle deflection can be performed without rotation interference.
[0035] The working principle of the utility model is as follows:
[0036] When loading the concrete vibration test bench, the concrete slab is moved to the front of the device through other transfer mechanisms, and the lower edge of the concrete slab is brought into contact with the roller 12 on the roller frame 3, and the entire concrete slab is moved to the device by sliding and rolling.
[0037] Then, the roller frame 3 is driven by the push plate cylinder 16 to flip the angle, slowly lowering the height of the concrete slab, and finally the concrete slab contacts the support block 10 on the vibration table 2 to complete the placement, and then the vibration motor 4 is started to perform a vibration test on the concrete slab placed on the upper plate 5.
[0038] After the test is completed, the push plate cylinder 16 drives the roller frame 3 to move upward, lifts the concrete plate off the upper plate 5, and then pushes the concrete plate to move it out.
[0039] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
