[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-4As shown, a multi-layer vibratory compaction device for staircase pouring includes: The vibrating section can be used to vibrate the concrete and aggregate inside the stair formwork 1; The lifting and vibrating parts are set on the lifting and vibrating parts, and the lifting and vibrating parts are used to control the height of the vibrating parts. The moving part and the lifting part are installed on the moving part, and the moving part can drive the lifting part and the vibrating part to move.

[0018] Furthermore, the vibrating section includes a mounting plate 3, which is inclined. Several hanging plates 2 are evenly arranged on the lower surface of the mounting plate 3. A contact mechanism is provided on the hanging plates 2, which includes a vertical rod 4. The vertical rod 4 is slidably connected to the hanging plates 2. A top plate 5 is provided at the upper end of the vertical rod 4. Eight limiting protrusions 6 are arranged in a circular array on the lower surface of the top plate 5. Eight slots 7 that cooperate with the limiting protrusions 6 are provided on the hanging plates 2. A fixing plate 8 is provided on the vertical rod 4. The hanging plates 2 are located between the top plate 5 and the fixing plate 8. A spring 9 is sleeved on the vertical rod 4. The spring 9 is located between the hanging plates 2 and the fixing plate 8. A horizontal plate 11 is provided at the lower end of the vertical rod 4. Two uprights 12 are provided at both ends of the lower surface of the horizontal plate 11. The two uprights 12 have different lengths. A vibration motor 13 is provided on the upper surface of the mounting plate 3.

[0019] Mounting plate 3 is made of aluminum alloy or plastic sheet. The interior of mounting plate 3 is not solid and has corresponding reinforcing ribs or holes to reduce the weight of mounting plate 3 and ensure that it can withstand the vibration of vibration motor 13. Mounting plate 3 and hanging plate 2 are made of the same material and are made as one piece.

[0020] The plumb bob 4, top plate 5, limiting protrusion 6, fixing plate 8, horizontal plate 11, and upright rod 12 are all made of metal. The plumb bob 4 and top plate 5, the plumb bob 4 and horizontal plate 11, and the horizontal plate 11 and upright rod can be connected by welding or bolts. The fixing plate 8 is fixed to the plumb bob 4 by welding. At the same time, the plumb bob 4, limiting protrusion 6, fixing plate 8, horizontal plate 11, and upright rod 12 can also be integrally formed by casting. The top plate 5 is connected to the plumb bob 4 by welding or bolts to make the connection of the plumb bob 4, top plate 5, limiting protrusion 6, fixing plate 8, horizontal plate 11, and upright rod 12 stable and able to resist the vibration of the vibration motor 13 without damage.

[0021] like Figure 5 As shown, there is a support platform 10 and a stair mold 1 placed on the support platform 10. After the steel frame is built inside the stair mold 1, concrete and stone can be poured into the stair mold 1. Because there is a lot of aggregate in the poured material, the material has poor fluidity. When the material is vibrated, the air inside the material can be quickly discharged. Before the material is over-vibrated, the material in each stair layer will not be transferred to the mold of the next layer in large quantities, thereby ensuring the quality of the stair product.

[0022] When vibrating the material inside the stair mold 1, all the uprights 12 are inserted into the stair mold 1 of the corresponding floor height. Then, the vibration motor 13 is started, and the vibration motor 13 generates vibration, which causes the mounting plate 3 to vibrate. When the mounting plate 3 vibrates, the vibration can be transmitted to the uprights 12 through the hanging plate 2, the vertical bar 4, and the horizontal plate 11. Through the vibration of the uprights 12, the air in the material can be expelled, so that the material is compacted.

[0023] Vibration motor 13 is selected to be suitable for the engineering environment type to improve its service life, and it needs to be maintained regularly to avoid damage to internal components.

[0024] Because the processed material contains a large amount of aggregate with a large particle size, the vibration frequency of the upright 12 is 50Hz to 100Hz, and 60Hz is selected in this embodiment. The working time is 8s to 12s, and 10s is selected in this embodiment. The volume of the processed material is 60cm×20cm×15cm, and the depth of the upright 12 is 8cm. In this case, as long as the upright 12 is within a 25 square centimeter range of the center of the material, the position of the upright 12 does not need to be changed to achieve vibration and air removal of the material in the staircase. As the processed material increases, such as if the length is long, a detachable crossbar can be installed at the lower end of the upright 12. It can be connected by bolts. The length of the crossbar is not greater than half the length of the stair tread and not less than 1 / 3 of the length of the stair tread. The additional crossbar can also effectively process the material.

[0025] Since the width of the stair treads varies, for stair treads of different widths, the limiting protrusion 6 can be moved out of the slot 7 by pressing the spring 9 upwards. Then, the plumb rod 4 can be rotated so that the two uprights 12 under the horizontal plate 11 can be inserted into the two adjacent stair treads. Then, the plumb rod 4 is released, and the position of the limiting protrusion 6 is adjusted appropriately so that the limiting protrusion 6 can re-enter the slot 7 under the action of the spring 9. When the limiting protrusion 6 enters the slot 7, it can prevent the plumb rod 4 from rotating, thereby improving the stability of the plumb rod 4 when transmitting vibration. In addition, a high-strength type of spring 9 is selected so that the limiting protrusion 6 can not pop out of the slot 7 under vibration.

[0026] Furthermore, the lifting unit includes a mounting groove 14, a screw 15 is rotatably connected inside the mounting groove 14, a handwheel 16 is provided at the upper end of the screw 15, a base 17 is threadedly connected to the screw 15, a reinforcing plate 18 is provided on the mounting plate 3, and the reinforcing plate 18 is connected to the base 17 by a rubber connector 19.

[0027] By turning the handwheel 16, the screw 15 can be rotated. Since the screw 15 is threadedly connected to the base 17 and the base 17 can slide in the mounting groove 14, the base 17 can move up or down along the screw 15 in the mounting groove 14 when the screw 15 is rotated. Then, the mounting plate 3 is moved through the rubber connector 19 and the reinforcing plate 18. When the mounting plate 3 is moved upward, the upright 12 can be removed from the stair mold 1. When the mounting plate 3 is moved downward, the upright 12 can be inserted into the stair mold 1.

[0028] The rubber connector 19 is used to reduce the vibration intensity transmitted from the vibratory motor 13 to the base 17, thereby improving the durability of the base 17. At the same time, the weight of the vibrating part makes the deformation of the rubber connector 19 less than 15% of its maximum deformation, so that the rubber connector 19 can still effectively reduce the vibration intensity.

[0029] Furthermore, the movable part includes a U-shaped support frame 20, an extension plate 21 is provided at one end of the support frame 20, two fixed wheels 22 are respectively provided on both sides of the lower surface of the support frame 20, a movable wheel 23 is provided on the lower surface of the extension plate 21, a connecting rod 24 is provided at the upper end of the movable wheel 23, the connecting rod 24 is rotatably connected to the extension plate 21, a handle 25 is provided at the upper end of the connecting rod 24, and a mounting groove 14 is provided on the support frame 20.

[0030] The support frame 20 can be moved to the support platform 10, and the direction of movement of the support frame 20 can be easily changed through the connecting rod 24, handle 25 and movable wheel 23.

[0031] The connecting rod 24 is bent to keep a greater distance between the handle 25 and the mounting groove 14, so as to avoid restricting the operation of the handle 25.

[0032] Furthermore, a support plate 26 is provided on the extension plate 21, and the connecting rod 24 is rotatably connected to the support plate 26. The support plate 26 is used to improve the stability of the connecting rod 24 during rotation and movement.

[0033] In this application, the parts involving rotating connections between the two components are all connected by bearings. At the same time, since the mounting groove 14 is exposed, it is convenient to apply lubricating grease to the surface of the screw 15.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
