[0001] The invention relates to the field of construction process equipment, in particular to a slit-type prefabricated groove demoulding device and method. Background Art

[0002] The slit-type drainage ditches are uniformly prefabricated in the processing plant, using plastic molds and cylindrical molds. The plastic mold is a rectangular frame with protruding ribs on the inner bottom surface of the plastic mold. The ribs are used to form the slit structure of the slit-type prefabricated ditch. The plastic mold is provided with circular holes on the two opposite side walls along the length direction of the ribs. The two circular holes are coaxially arranged. The cylindrical mold matches the two circular holes. The cylindrical mold is inserted into the plastic mold from the circular holes, and the ribs abut against the outer circular surface of the cylindrical mold. The cylindrical mold is used to form the drainage channel structure of the slit-type prefabricated ditch. The prefabricated slit structure and the drainage channel structure are connected through the cooperation of the ribs and the cylindrical mold.

[0003] When demoulding, you need to pull out the cylindrical mold first, and then separate the plastic mold from the prefabricated part to proceed to the next step of construction.

[0004] To separate the plastic mold from the prefabricated part, the traditional demoulding method is manual flipping. Because the prefabricated part is heavy and prone to edge collapse during the flipping process, it requires the collaboration of multiple construction workers, which makes the construction difficult and the demoulding quality cannot be guaranteed.

The rotating shaft is used to pass through a through hole on a mold for loading the slit-type prefabricated ditch. The diameter of the rotating shaft is smaller than the width of the slit on the slit-type prefabricated ditch.

[0008] By adopting the gap-type prefabricated groove demoulding device described in the present invention, the mold can be lifted and rotated downward through the cooperation of the hanger and the rotating shaft, and the rotating shaft can be moved out of the gap to achieve the purpose of demoulding. The hanger and the rotating shaft are not easy to deform, and the prefabricated parts will not be squeezed and broken during operation. Only two workers are needed to complete the lifting and flipping of the mold. The demoulding device has the advantages of simple structure, easy operation and efficient construction. Compared with traditional demoulding methods, it can greatly improve construction efficiency and ensure construction quality.

[0009] Preferably, the rotating shaft includes a shaft rod and a sleeve, the sleeve is sleeved on the outside of the shaft rod, the two hooks are hooked on both ends of the shaft rod, and the diameter of the sleeve is smaller than the width of the gap.

[0010] With this structure, the sleeve can rotate relative to the shaft rod, so that when the mold is turned over, the sleeve moves on the inner wall of the preform and the shaft rod can remain stationary, reducing friction resistance.

[0011] Further preferably, the sleeve and the shaft rod are connected via a plurality of bearings.

[0012] With this structure, the sliding friction of the sleeve moving on the inner wall of the preform is converted into rolling friction through the bearing, further reducing frictional resistance and facilitating manual turning over of the mold.

[0028] The present invention adopts a method for demoulding a slit-type prefabricated ditch. Since the concrete will be compacted tightly when the mold is used to make the prefabricated part, there is a strong friction between the prefabricated part and the mold after the concrete solidifies. Therefore, after the mold is flipped by the cooperation of the hanger and the rotating shaft, the prefabricated part will not fall directly from the mold. After flipping, the hanger descends and the vibration when the prefabricated part lands on the ground is used to loosen the slit-type prefabricated ditch and the mold. Then the hanger is lifted to demould, and the rotating shaft is moved out of the gap. The demoulding method has simple steps, easy operation and good effect.

Specifically, the power of the motor 21 is 500w. With this structure, the motor 21 is used as the power, and the lifting rope 23 and the hook 24 are used as the power transmission link. The human only needs to operate the starter and stop switch of the control panel 25 to raise and lower the sling 3 to control the lifting or lowering of the mold 03.

[0048] Example 2

[0049] like Figures 1 to 5 As shown, the present invention provides a method for demoulding a slit-type prefabricated groove, using the slit-type prefabricated groove demoulding device as described in Example 1. The demoulding method includes the following steps:

[0050] The cylindrical mold in the through hole 04 is pulled out;

[0051] The rotating shaft 4 is passed through the through hole 04, the sling 3 is lowered, and the two hooks 32 are hung on both ends of the rotating shaft 4;

[0052] The hanger 3 rises, and the hook 32 drives the rotating shaft 4 to lift the slit-type prefabricated trench 01 and the mold 03. The mold 03 is manually rotated so that its opening faces downward. At this time, the rotating shaft 4 moves along the inner wall of the slit-type prefabricated trench 01 and aligns with the slit 02.

[0053] The sling 3 descends and places the mold 03 of the slit-type prefabricated trench 01 on the ground. The vibration when the slit-type prefabricated trench 01 falls to the ground causes the slit-type prefabricated trench 01 and the mold 03 to separate.

[0054] The sling 3 rises, and the hook 32 drives the rotating shaft 4 to lift the mold 03. The slit-type prefabricated groove 01 and the mold 03 are separated, and the rotating shaft 4 moves out of the slit 02.

[0055] The rotating shaft 4 is removed from the hook 32 , and the mold 03 and the hanger 3 are separated.

[0056] The present embodiment describes a method for demoulding a slit-type prefabricated ditch. Since the concrete will be compacted tightly when the mold 03 is used to make the prefabricated part, there is a strong friction between the prefabricated part and the mold 03 after the concrete solidifies. Therefore, after the mold 03 is flipped over by the cooperation of the hanger 3 and the rotating shaft 4, the prefabricated part will not fall directly from the mold 03. After flipping, the hanger 3 descends and utilizes the vibration when the prefabricated part lands to loosen the slit-type prefabricated ditch 01 and the mold 03. Then, the hanger 3 is lifted to demould, and the rotating shaft 4 is removed from the slit 02. The demoulding method has simple steps, is easy to operate, and has good results.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
