There are quality problems such as segregation, bubbles and large color difference.

The technical scheme that the utility model solves its technical problem adopts is:

A mobile split concrete vibrating table, comprising two rows of vibrating tables left and right, a mold moving channel is arranged between the two rows of vibrating tables; the vibrating table includes a mobile frame, on which a steel box, an attached vibrating motor is installed inside the steel box, an electromagnet for absorbing molds is arranged on the inner wall top surface or both sides of the steel box, and an outer wall top surface of the steel box is set There is a shock-absorbing support, and an eccentric wheel is housed on the vibration motor.

Further, the mobile frame includes a frame body, a rotating rod and a hydraulic telescopic arm; one end of the rotating rod is installed on the top of the frame body, the other end is connected to the steel box, and one end of the hydraulic telescopic arm It is installed in the middle of the frame body, and its other end is installed in the middle of the rotating rod.

Further, the shock-absorbing support is a rubber pad, and the vibration amplitude can be adjusted by adjusting the thickness and stiffness of the rubber pad.

Furthermore, the steel box is welded by low-alloy steel plate or carbon steel plate, and the size and quantity of the box should match the size and weight of the mould.

Further, the eccentric wheel is composed of a fixed eccentric block, a movable eccentric block and a flange, the flange is installed on the vibration motor, and the fixed eccentric block and the movable eccentric block are placed in the flange , and is fixed by a locking disc and a locking bolt.

The beneficial effects of the utility model are: the vibrating table of the utility model adopts a movable vibration mode, which can evenly transmit the vibrating force to the mold according to the demand. Compared with the prior art, it adopts two rows of vibrating boxes Coordinated operations, and a logistics channel is reserved in the middle part. It adopts the coordinated operation method of the movable eccentric block and the fixed eccentric block, and the size of the exciting force can be adjusted according to the demand. The vibration motor adopts frequency conversion control technology, so the vibration can be adjusted according to the demand. frequency. The mobile frame vibrates the steel box through the hydraulic telescopic arm, and the electromagnet is adsorbed on the bottom surface of the mold. The vibration amplitude is controlled by adjusting the thickness of the rubber pad on the box surface and the stiffness of the rubber, so that the production speed of concrete precast products is fast and the density is high. And solve Bubbles, sticky skin, large color difference and other common quality problems.

Detailed ways

Below in conjunction with accompanying drawing. The utility model is described further.

A specific embodiment of a mobile split concrete vibrating table is shown in Figure 1, which includes two rows of vibrating tables on the left and right, and a mold moving channel is arranged between the two rows of vibrating tables.

The specific structure of a single vibrating table includes: a mobile frame, a steel box 6 is housed on the mobile frame, an attached vibrating motor 4 is housed in the steel box, and an eccentric wheel 5 is housed on the vibrating motor 4; in addition, An electromagnet 7 is installed on the inner cavity top surface of steel case 6, and this electromagnet 7 is used for absorbing and fixing mould, and can also be arranged on the inner wall both sides of casing. A shock-absorbing support 8 is provided on the top surface of the outer wall of the steel box 6, and the mold 9 is placed on the shock-absorbing support 8. The shock-absorbing support 8 is a rubber pad, and the vibration amplitude can be adjusted by adjusting the thickness and stiffness of the rubber pad.
