Technical Field

[0001] The invention relates to the technical field of prefabricated part steam curing, and in particular to a steam curing device for curing cement prefabricated parts. Background Art

[0002] Concrete products are widely used, from large bridges across rivers to small roadside electric poles. Each of them is an important participant in our lives. Without concrete, it can be said that there would be no rapid development of our modern society. The steam curing method of precast concrete parts is a technology that effectively improves the strength and durability of precast parts. Steam curing can provide constant high humidity and suitable temperature after the initial setting of concrete, promoting the full reaction of cement.

[0003] In the comparative document of a steam curing device for preform production proposed in publication number CN112207973B, it is specifically proposed that "it includes a first clamping plate, a second clamping plate, a steam curing mechanism, an air inlet pipe, an air storage tank, a pressure tank, a piston, a return spring, a pressure relief mechanism and a material injection tank."

[0004] The above-mentioned comparative document also has the following defects: in the comparative document, it is necessary to first pour the cement mixture into the injection groove, and then turn on the external steam engine after solidification, and steam-cure the cement pipe in the injection groove through the steam-curing mechanism. The inventors found that the device not only has low working efficiency but also releases steam through the piston hole, so that the steam-curing area is limited. For this reason, we propose a steam-curing device for curing cement prefabricated parts. Summary of the invention

[0031] Reference Figure 4-5 The partition assembly 6 includes a column 61 arranged on both sides of the inner wall of the cavity 7, a cylinder 62 arranged at one end of the column 61, and a rotating door 63 rotatably arranged on the cylinder 62, and a torsion spring is arranged between the rotating door 63 and the cylinder 62.

[0032] It is worth mentioning here that a number of cavities 7 of equal size are separated by the partition assembly 6, and the cavities 7 in the closed area are used simultaneously with the cavities 7 in the open area, so that the steam curing of cement pipe prefabricated parts will not be affected while loading and unloading.

[0033] Reference Figure 4-6The conveying assembly 9 includes a steam outlet pipe 91 arranged at one end of the steam pump 8, a collecting and distributing point 92 arranged at one end of the steam outlet pipe 91, a steam distribution pipe a93 leading to the cavity 7 through the collecting and distributing point 92, a steam distribution pipe b94 arranged at the lower end of the collecting and distributing point 92, and a hose 96 distributed on the side of the rotating shaft 95. A cavity 97 is arranged inside the rotating shaft 95, and the upper end of the cavity 97 is rotatably connected to the steam distribution pipe b94, and the hose 96 is connected to the cavity 97.

[0034] In this embodiment, the steam is divided into two groups, upper and lower, and respectively transported to the cavity 7 by the transport assembly 9, so as to ensure that both the inner and outer walls of the cement pipe prefabricated part can be fully steam cured.

[0035] Reference Figure 4 The lifting assembly 10 includes a steam separation pipe c101 that slides up and down on the turntable 2, a fixing rod 102 arranged at the lower end of the steam separation pipe c101, a steam cover 103 arranged at the upper end of the steam separation pipe c101, and a plurality of steam outlet holes 104 arranged on the peripheral side of the steam cover 103.

[0036] It is worth mentioning that, by arranging a lifting assembly 10 on the inner side of the cement pipe preform, the lifting assembly 10 can drive the steam to move up and down on the inner side of the cement pipe preform, thereby ensuring sufficient steam curing on the inner side.

[0037] Reference Figure 4 The guide rail 11 is provided with a plurality of grooves a111 and protrusions a112, and the grooves a111 and the protrusions a112 are connected in an arc.

[0038] In this embodiment, by providing a plurality of grooves a111 and protrusions a112 on the guide rail 11 , the lifting assembly 10 operates along a predetermined track of the guide rail 11 , thereby ensuring that the lifting speed and frequency of the lifting assembly 10 are consistent.

[0039] Reference Figure 4-6 The lower ends of the inner and outer walls of the steaming and curing bin 5 are both provided with grooves b52, and the upper surface of the turntable 2 is provided with protrusions b21 corresponding to the grooves b52.

[0040] It is worth mentioning that the sealing performance of the steam in the steaming bin 5 can be improved by the arrangement between the steaming bin 5 and the turntable 2 .

[0041] Reference Figure 3 The upper end surface of the turntable 2 is respectively provided with a loading end 22 and a unloading end 23, and both the loading end 22 and the unloading end 23 are open cavities 7, and the cavity 7 of the unloading end 23 is not connected with the steam distribution pipe a93.

[0042] In this embodiment, the uncertainty of manual material placement and removal can be avoided by using a robot to grab the cement pipe prefabricated part in the open cavity.

[0043] The working process is as follows:

[0044] The manipulator puts the cement pipe preform into the cavity 7 of the feeding end 22, starts the motor 3, and the turntable 2 rotates, driving the cement pipe preform to rotate along the direction of the turntable 2. During the rotation process, the cement pipe preform rotates to the partition assembly 6, pushing the rotating door 63 to both sides. A torsion spring is arranged between the rotating door 63 and the cylinder 62, and the torsion spring can automatically reset.

[0045] While the turntable 2 rotates, the fixed rod 102 in the lifting assembly 10 rotates on the guide rail 11 according to a predetermined trajectory, driving the steam hood 1103 to also perform lifting motion along the trajectory inside the cement pipe prefabricated part.

[0046] Start the steam pump 8, and the steam outlet pipe 91 in the conveying component 9 conveys the steam generated in the steam pump 8 to the collecting and distributing point 92, and then from the collecting and distributing point 92 to the cavity 7 through the steam distribution pipe a93 and the hose 96 respectively. The difference is that the steam distribution pipe a93 directly conveys the steam to the cavity 7, and the hose 96 conveys the steam to the steam hood 103, and the characteristics of the hose 96 itself do not affect the lifting and lowering of the steam distribution pipe c101.

[0047] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art under the technical guidance of the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
