[0002] D-type interlocking piece is one of the main structural forms of underwater drainage bottom protection for waterway regulation. It is widely used in waterway regulation due to its strong integrity, stable structure, and efficient operation during water drainage. It is convenient to construct and has good overall performance. The D-type interlocking piece is a C20 concrete block with a circular plane shape, a diameter of 36cm, a thickness of 10cm, a weight of 21.39kg, and a spacing of 14cm between concrete blocks. The prefabricated concrete ballast blocks are connected in series with polypropylene ropes. Each unit is 4m×5m in size. One interlocking piece consists of 80 circular concrete blocks.

[0003] Before the upper and lower molds are combined to pour concrete, a release agent needs to be sprayed on the area where the prefabricated device contacts the concrete.

This operation requires the upper mold to be hung in the air and rotated. The operation has many steps, is difficult, and is time-consuming. Therefore, the existing interlocking piece prefabricated mold needs to be further optimized. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 , 2 As shown, the embodiment of the utility model proposes an interlocking sheet prefabrication device, including an upper mold 3 and a lower mold 1, wherein a plurality of upper chambers and a plurality of lower chambers 2 are respectively arranged between the upper mold 3 and the lower mold 1, and each of the upper mold 3 and the lower mold 1 has a corresponding mold frame. In this embodiment, the upper mold 3 is a plate-shaped integral structure. It also includes a box 13, a spray rod 5 and a plurality of lifters 7. The box 13 is fixedly arranged on the top of the upper mold 3, and the box 13 is used to store a release agent. The spray rod 5 is a straight rod structure, and a center hole is arranged inside. The length of the spray rod 5 is consistent with the width of the upper mold 3. A plurality of spray holes 16 are arranged side by side on the upper and lower sides of the spray rod 5, and the spray holes 16 are in the shape of a trumpet. An opening is arranged on the top of the box 13, and a ball valve is arranged at the opening position. The staff pours the release agent into the opening. A hose 15 for communication is arranged between the bottom of the box 13 and one end of the spray rod 5. Several sliding connection units are evenly arranged between the spray rod 5 and the upper mold 3, and the sliding direction of the spray rod 5 is parallel to the side of the upper mold 1. The lifter 7 includes a fixed section and a movable section arranged up and down, the fixed section is fixedly connected to the four corners of the upper mold 3, the movable section extends vertically downward, and a roller 10 is arranged at the bottom of the movable section. The upper mold 3 protrudes from the lower mold 1 at both ends in the sliding direction of the spray rod 5. When the upper mold 3 and the lower mold 1 are ready to be molded, the spray rod 5 moves to one end of the upper mold 3 to avoid damage or deformation of parts caused by contact between the spray rod 5 and the lower mold 1.

[0022] Preferably, guide rails 11 are horizontally arranged on both sides of the lower mold 1, and a support structure is arranged at the bottom of the guide rails 11 or the bottom of the guide rails 11 is fixed to the ground. One end of the guide rail 11 extends to a region away from the lower mold 1, and a groove is arranged at the top of the guide rail 11, and the groove is adapted to the roller 10. To prevent the cement floor from being damaged and uneven after the upper mold 3 reciprocates for several times and affects the movement of the upper mold 3, the guide rails 11 made of metal can support the upper mold 3.

[0023] Preferably, a plurality of support columns 6 are evenly arranged at the bottom of the lower mold 1. When the overall size of the device is large, a concave appears in the middle, which causes the upper mold 3 and the lower mold 1 to fail to close properly, and the support columns 6 play a role of stable support at the bottom of the lower mold 1.

[0024] Preferably, the upper mold 3 is provided with a first traction rope 8 on both sides of the lifter 7, and the two ends of the spray rod 5 are respectively provided with a second traction rope 9. When the lifter 7 separates the upper mold 3 and the lower mold 1, the staff pulls the first traction rope 8 to move the upper mold 3 away from the lower mold 1, and then the staff pulls the second traction rope 9 to make the spray rod 5 pass between the upper mold 3 and the lower mold 1, and at the same time, the release agent is sprayed from the spray hole 16 onto the upper mold 3 and the lower mold 1.

[0025] Preferably, the sliding connection unit includes four T-shaped sliding grooves 4 arranged in parallel on the bottom surface of the upper mold 3 and a corresponding T-shaped sliding member 12 arranged on the spraying rod 5, and the sliding member 12 is slidably matched with the sliding grooves 4. The intervals of the sliding grooves 4 are equal, so that the spraying rod 5 maintains a horizontal state, and the release agent in the spraying rod 5 is evenly sprayed onto the upper mold 3 and the lower mold 1.

[0026] Preferably, a pressure pump is provided on the rubber hose 15 to increase the spraying pressure of the release agent so that the release agent can be better attached to the surface of the prefabricated device.

[0027] Preferably, the lifter 7 is an electric structure, and a plurality of lifters 7 are electrically connected and provided with a controller. When the mold needs to be opened, the lifters 7 are controlled to rise synchronously to avoid the problem that the upper mold 3 cannot be separated from the lower mold 1 due to unbalanced force, or the quality of the preform is affected.

[0028] Preferably, a reel 14 for winding up the rubber hose 15 is fixedly provided on the upper mold 3, so that the rubber hose 15 can be neatly placed during spraying.

[0029] The mold frame of the lower mold 1 is composed of a plurality of vertically arranged plates. The mold frame includes a plurality of plates arranged in the horizontal and vertical directions, and each bottom of the lower chamber 2 has at least three vertical and three horizontal plates. The plates are made of metal and connected by electric welding.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
