The vibration of the high-frequency vibration motor is used as the vibration source for concrete molding to make the concrete dense and complete the prefabrication of the lower chamber. However, this molding method has the problem of negative pressure during demolding. Since the inner wall of the prefabricated chamber will fit tightly with the inner mold, demolding can be performed directly. As the inner mold and the chamber separate, a cavity will appear between the cavity. As the volume of the cavity continues to increase, a vacuum phenomenon will occur, which may cause damage to the chamber that has not been completely dried and hardened. Therefore, based on the above problems, a vertical high-frequency vibration motor is proposed to prefabricate the concrete inspection shaft lower chamber mold. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, the inner mold, outer mold, bottom tray and base are provided so that the support hoop can support and lift the bottom tray, and the connection between the outer shell of the outer mold and the bottom tray is locked by pulling the locking mechanism, so that a prefabricated chamber is formed between the outer shell, the inner shell and the bottom tray, and a reserved hole mold is installed at the mold entrance. At this time, dry hard concrete can be poured into the chamber, the well chamber cover is covered and the screw sleeve is screwed on the screw rod so that the well chamber cover and the inner top plate have a connection relationship, and the vibration motor can be started to vibrate the concrete so that the concrete is quickly compacted and formed to obtain the well chamber. When it is necessary to demould the well chamber, the reserved hole mold is first removed, and then the locking mechanism is opened to disconnect the outer shell from the bottom tray, and the outer shell and its attached structures are extracted and lowered, leaving only the well chamber cover, and then the well chamber cover is removed. The plate is lifted up, and since the well chamber cover plate and the inner top plate are locked to the well chamber by screws and screw sleeves, lifting the well chamber cover plate can drive the well chamber and the inner top plate to move up, so that the inner top plate is disconnected from the inner shell, so that when the well chamber is moved up and demoulded, there will be no cavity vacuum absorption, and negative pressure caused by demoulding separation of the well chamber and the inner mold is avoided, so that the vertical high-frequency vibration motor prefabricates the lower well chamber mold of the concrete inspection well.

The splicing body and the middle joint can be spliced ​​into a complete hole position mold installed in the mold entrance, so that the cast well chamber has holes on both sides. When the well chamber needs to be demoulded, the reserved hole mold needs to be removed first. The operation is as follows: at the same time, the rotating wheels of the transmission parts on both sides are rotated to rotate the screw rod. Since the thread sleeve and the sleeve shell are limited by the limit road and cannot rotate, the rotation of the screw rod will cause the thread sleeve and the sleeve shell to move. The displacement of the sleeve shells on both sides will push the push block to move toward the middle joint, squeeze the guide block of the middle joint, and the squeezed guide block will drive the middle plate to move outward, so that the upper and lower parts of the middle plate The end face is disengaged from the manufactured well chamber, and then the middle joint is completely pulled out to complete the removal of the middle joint, so that a spacing appears between a group of spliced ​​bodies. At this time, the spliced ​​body is in contact with the manufactured well chamber only on one side of the curved surface, and is no longer supported by the middle joint. At this time, the spliced ​​body can be easily removed to complete the removal of the reserved hole mold, thereby realizing the ability of the concrete inspection well lower well chamber mold to remove the reserved hole mold conveniently and quickly without causing damage to the lower well chamber when demolding the lower well chamber. This solves the problem that when the concrete inspection well lower well chamber mold is demolded from the lower well chamber, the existing reserved hole molds are all integrated structures with a large contact surface with the well chamber hole position, making it inconvenient to remove the reserved hole mold and easily causing damage to the well chamber hole position.

[0031] Working process: The operation process of the lower well chamber mold of the vertical high-frequency vibration motor precast concrete inspection well is as follows: the supporting hoop 3 can support and lift the bottom tray 4, and the connection between the outer shell 51 of the outer mold 5 and the bottom tray 4 is locked by pulling the locking mechanism 53, so that a prefabricated chamber is formed between the outer shell 51, the inner shell 21 and the bottom tray 4, and the reserved hole mold 6 is installed at the mold entrance 55. At this time, dry hard concrete can be poured into the chamber, and the well chamber cover 54 is covered and the screw sleeve 26 is screwed on the screw 25 to make a connection between the well chamber cover 54 and the inner top plate 24. The vibration motor 23 can be started to vibrate the concrete, so that the concrete can be quickly compacted and formed to obtain the well chamber 7. When it is necessary to demold the well chamber 7, the reserved hole mold 6 is first removed, and then the locking mechanism 53 is opened to disconnect the outer shell 51 from the bottom tray 4, and the outer shell 51 and its attached structures are extracted, leaving only The well chamber cover plate 54 is lowered, and then the well chamber cover plate 54 is lifted up. Since the well chamber cover plate 54 and the inner top plate 24 are locked to the well chamber 7 by the screw 25 and the screw sleeve 26, the lifting of the well chamber cover plate 54 can drive the well chamber 7 and the inner top plate 24 to move upward, so that the inner top plate 24 is disconnected from the inner shell 21, so that when the well chamber 7 is moved up and demoulded, there will be no cavity vacuum absorption, and the demoulding separation of the well chamber 7 and the inner mold 2 will avoid generating negative pressure, so that the vertical high-frequency vibration motor prefabricated concrete inspection well lower well chamber mold uses the vibration motor 23 as a vibration source to accelerate the compaction molding speed of concrete, and improve the prefabrication efficiency of the lower well chamber, and the separation of the lower well chamber and the inner mold 2 can avoid generating negative pressure during demoulding, thereby improving the manufacturing rate of the lower well chamber, and the well chamber cover plate 54, the inner top plate 24, the screw 25, and the screw sleeve 26 can be removed from the well chamber 7 after demoulding, and the remaining holes can be subsequently repaired in a centralized manner;The process of removing the reserved hole mold 6 is as follows: the splicing main body 61 and the middle connecting part 62 are spliced ​​and connected, and the splicing main body 61 and the middle connecting part 62 can be spliced ​​into a complete hole position mold installed in the mold entrance 55, so that the cast well chamber 7 has holes on both sides. When the well chamber 7 needs to be demoulded, the reserved hole mold 6 needs to be removed first. The operation is as follows: at the same time, the rotating wheels 631 of the transmission parts 63 on both sides are rotated to rotate the screw rod 632. Since the wire sleeve 633 and the sleeve shell 634 are limited by the limit road 613 and cannot rotate, the rotation of the screw rod 632 will cause the wire sleeve 633 and the sleeve shell 634 to move, and the displacement of the sleeve shells 634 on both sides will push the push block 635 to the middle connecting part 62. The guide block 622 of the middle joint 62 is moved, and the squeezed guide block 622 drives the middle plate 621 to move outward, so that the upper and lower end surfaces of the middle plate 621 are out of contact with the manufactured well chamber 7, and then the middle joint 62 is completely pulled out to complete the removal of the middle joint 62, so that a gap appears between a group of splicing bodies 61. At this time, the splicing body 61 is in contact with the manufactured well chamber 7 on only one side of the curved surface, and is no longer supported by the middle joint 62. At this time, the splicing body 61 can be conveniently removed to complete the removal of the reserved hole mold 6, so that when the lower well chamber mold of the concrete inspection well is demoulded, the reserved hole mold 6 can be removed conveniently and quickly without causing damage to the lower well chamber. ;
