[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a roller compacted concrete vibration forming device.

[0025] The utility model provides Figure 1-3 The roller compacted concrete vibration forming apparatus shown includes a base 1, a positioning frame 2 is fixedly connected to the upper surface of the base 1, a mold 3 is slidably arranged inside the positioning frame 2, a plurality of telescopic rods 4 are fixedly connected between the mold 3 and the base 1, a spring 5 is slidably sleeved on the rod wall of each telescopic rod 4, a first rotating rod 6 is rotatably connected to the inside of the positioning frame 2, an eccentric roller 7 is fixedly sleeved on the rod wall of the first rotating rod 6, a driving mechanism is arranged on one side of the positioning frame 2, the first rotating rod 6 is rotated by the driving mechanism, a pressing plate 8 is slidably arranged inside the mold 3, a U-shaped plate 9 is arranged on the upper surface of the base 1, an adjustment mechanism is arranged between the U-shaped plate 9 and the pressing plate 8, a transmission mechanism is arranged on the upper surface of the U-shaped plate 9, and the driving mechanism drives the adjustment mechanism to work through the transmission mechanism.

[0026] The driving mechanism can be used to rotate the first rotating rod 6, which then drives the eccentric roller 7 to rotate, and then the mold 3 can vibrate up and down. In this process, the air in the concrete can be discharged, and the concrete can be made more compact through the action of the pressing plate 8.

[0027] In order to make the first rotating rod 11 rotatable, Figure 1-3As shown, the driving mechanism includes a motor 10, a second rotating rod 11, a first bevel gear 12 and a second bevel gear 13. The second rotating rod 11 is rotatably connected between the base 1 and the U-shaped plate 9 and the upper end thereof passes through the upper surface of the U-shaped plate 9. The motor 10 is fixedly connected to the lower surface of the base 1. The lower end of the second rotating rod 11 passes through the upper surface of the base 1 and is fixedly connected to the output end of the motor 10. One end of the first rotating rod 6 passes through one side of the positioning frame 2. The first bevel gear 12 is fixedly sleeved on the rod wall at one end of the first rotating rod 6. The second bevel gear 13 is fixedly sleeved on the rod wall of the second rotating rod 11 and meshes with the first bevel gear 12.

[0028] The motor 10 is started to rotate the second rotating rod 11 , and then the first rotating rod 6 can be rotated through the first bevel gear 12 and the second bevel gear 13 .

[0029] And in order to make the pressing plate 8 move downward, as Figure 1-2 As shown, the adjustment mechanism includes a screw rod 14 and a sleeve 15. A through hole is opened on the upper surface of the U-shaped plate 9. The screw rod 14 is rotatably connected to the inside of the through hole. An internal threaded hole is opened inside the sleeve 15. The sleeve 15 is threadedly sleeved on the outer surface of the screw rod 14 through the internal threaded hole. The lower end of the sleeve 15 is fixedly connected to the upper surface of the pressure plate 8. The transmission mechanism includes a driving gear 16 and a driven gear 17. The driving gear 16 is fixedly sleeved on the rod wall at the upper end of the second rotating rod 11, and the driven gear 17 is fixedly sleeved on the rod wall at the upper end of the screw rod 14 and meshes with the driven gear 17.

[0030] When the second rotating rod 11 rotates, the driving gear 16 rotates accordingly, and then drives the driven gear 17 to rotate, so that the screw rod 14 can rotate, and then the sleeve 15 moves downward and drives the pressing plate 8 to move and compact the concrete. At the same time, the size of the driving gear 16 is much smaller than that of the driven gear 17, so the pressing plate 8 moves downward relatively slowly.

[0031] In order to facilitate the discharge of gas, Figure 2 As shown, two mounting holes are provided on the upper surface of the pressing plate 8, and filter screens 18 are fixedly connected inside the two mounting holes.

[0032] The filter 18 can be used to discharge the air inside the concrete.

[0034] The positioning frame 2 can play a supporting and limiting role to prevent the mold from tilting. At the same time, the outer surface of the mold 3 and the inner wall of the positioning frame 2 are both smooth, which can reduce the friction between the mold 3 and the positioning frame 2.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
