The clamping is ensured to be more stable. The clamping cylinder 4 is used for driving the clamping jaw 5 to move at the automatic tail end, so that the clamping jaw 5 is pressed against the outer side wall of the mold 3, for example, a rack is arranged on a telescopic rod of the clamping cylinder 4, a gear is arranged at a connecting part of the clamping jaw 5, and the linear motion of the telescopic rod of the clamping cylinder 4 is converted into the rotary motion of the clamping jaw 5.
In order to adjust the height of the vibration platform 21 more stably, the vibration platform 21 is adjusted in height in a smaller space. As shown in fig. 1, 2, 3 and 6, in some embodiments of the present application, the vibration device 2 includes a first air spring 22, and the first air spring 22 is disposed on a lower surface of the vibration platform 21.
The air spring is a spring in which a retractable closed container is filled with compressed air and the elastic action of the air is utilized. Commonly known as air bags, air bag type cylinders, leather bag cylinders and the like. The air spring is formed by filling compressed air into a sealed container and realizing the elastic action by utilizing the compressibility of the air. The working principle is that inert gas or oil-gas mixture is filled in a closed pressure cylinder, the pressure in a cavity is several times or dozens of times higher than the atmospheric pressure, and the motion of a piston rod is realized by utilizing the pressure difference generated by the fact that the cross section area of the piston rod is smaller than that of the piston. Due to the fundamental difference in principle, the gas spring has very remarkable advantages compared with the common spring: the speed is relatively slow, the dynamic force change is not large (generally within 1: 1.2), and the control is easy. In the embodiment of the present application, the first air spring 22 is a bag type air spring, and is composed of a rubber air bag sandwiched with a cord and compressed air sealed therein. The inner layer of the air bag is made of airtight rubber, and the outer layer is made of oil-resistant rubber.

The electromagnet 24 is arranged at the bottom of the vibration platform 21, after the vibration platform 21 jacks up the die 3, the electromagnet 24 is electrified, a certain suction force is applied to the die 3 through the electromagnet 24, namely, the pressure of the die 3 on the vibration platform 21 is increased, and the die 3 is in surface contact with the vibration platform 21, so that the maximum static friction force between the die 3 and the vibration platform 21 is increased, and the stability of the die 3 is further ensured. After concrete pouring and vibration tamping in the mould 3 are completed, the power supply to the electromagnet 24 is cut off, so that the electromagnet 24 loses magnetic force.
Further, in some embodiments of the present application, the vibration device 2 further includes a vibration motor 25; the vibration motor 25 is disposed on the lower surface of the vibration platform 21 to drive the vibration platform 21 to vibrate. Through directly being in vibrating platform 21's lower surface sets up vibrating motor 25, through vibrating motor 25 drives vibrating platform 21 vibrates the tamping, avoids adopting transmission's energy loss to and cause the huge problem of equipment.
In order to avoid the interference of the roller conveyor line 1 with the vibration tamping of the vibration platform 21 when the vibration platform 21 vibrates, as shown in fig. 2 and 3, in some embodiments of the present application, a second air spring 6 is arranged at the bottom of the roller conveyor line 1; the second air spring 6 drives the roller conveyor line 1 to descend, so that the roller conveyor line 1 is far away from the vibration platform 21. Roller transfer chain 1 can divide into the multistage formula combination 2 top the roller transfer chain 1 can be the single section transfer chain, and is separable with the transfer chain of both sides, and in practical application, the multistage transfer chain is for splicing together, and there is less gap in the centre, as long as can guarantee that the roller interval is continuous. When the roller conveyor line 1 transports the die 3, the second air spring 6 is in an inflated state, and after the vibrating platform 21 raises the height to jack up the die 3, the second air spring 6 is deflated to enable the height of the roller conveyor line 1 to further lower relative to the vibrating platform 21, namely, the roller conveyor line 1 is far away from the vibrating platform 21 as far as possible, so that the vibration tamping of the vibrating platform 21 is avoided being influenced.
It should be noted that, even when the height of the vibration platform 21 is not raised, after the compressed air of the second air spring 6 is released, the horizontal height of the conveying plane of the roller conveyor line 1 can be made lower than the horizontal height of the upper plane of the vibration platform 21, so as to ensure that, when the height adjustment of the vibration platform 21 is in problem, there is an alternative that the second air spring 6 is deflated to drop the mold 3 on the vibration platform 21.
According to the technical scheme, the concrete vibrating table comprises a roller conveying line 1 and vibrating devices 2 arranged below the roller conveying line, wherein the vibrating devices 2 are arranged between two rollers of the roller conveying line 1, the number of the vibrating devices 2 is not less than two, and the distance between every two adjacent vibrating devices 2 is less than the length of a mold 3; the vibrating device 2 comprises a vibrating platform 21 with adjustable height, and after the vibrating platform 21 is lifted, the horizontal height of the upper plane of the vibrating platform 21 is higher than that of the conveying plane of the roller conveying line 1, so that the vibrating platform 21 supports the die 3 and drives the die 3 to vibrate.
In the practical application process, after the roller conveying line 1 conveys the die 3 to the position above the vibrating device 2, the roller conveying line 1 stops, then the height of the vibrating platform 21 rises, the die 3 is jacked up from the roller conveying line 1, when the vibrating platform 21 reaches the highest position, the die 3 is completely separated from the conveying plane of the roller conveying line 1, concrete is poured into the die through concrete pouring equipment, meanwhile, the vibrating platform 21 starts to vibrate, the concrete in the die 3 is vibrated and tamped, and therefore the concrete pouring is achieved, the vibrating and tamping are carried out, and the concrete pouring efficiency of the sleeper die is improved.
