Description

Technical Field

[0001] The present invention relates to the technical field of building engineering construction, and in particular to a pre-curing device for reinforced concrete prefabricated components, a production line and a processing method thereof. Background Art

[0002] At present, prefabricated components need to be transported to the curing station for pre-curing after pouring and vibration. After curing is completed, the surface needs to be roughened according to the requirements of the specifications.

[0003] Pre-curing of prefabricated components requires heating and evaporating the moisture on their surface to reduce the working time of the roughening station.

[0004] The current pre-curing method is to add heating equipment next to the workstation, which cannot be completed in factories with high production efficiency. The prefabricated components have to leave the pre-curing station before the heat is transferred to them.

[0005] In addition, regarding the direction names mentioned in this case, in the art, they are usually interpreted as follows:

[0006] X direction refers to the direction of conveying of prefabricated components;

[0007] Y direction, a vertical direction perpendicular to the conveying direction of the prefabricated components;

[0008] The Z direction is a horizontal direction perpendicular to the conveying direction of the prefabricated components. Summary of the Invention

[0009] The object of the present invention is to provide a pre-curing device for reinforced concrete prefabricated components, a production line and a processing method thereof, so as to improve the processing efficiency of pre-curing.

[0010] The technical solution of the present invention is: a pre-curing device for reinforced concrete prefabricated components includes a working platform, a support assembly, a hot air blower and a heat preservation cover for blowing the hot air from the hot air blower through a set air duct, the support assembly is raised and lowered relative to the working platform, the hot air blower is arranged at the lifting end of the support assembly, the heat preservation cover is fixed on the support assembly and is located next to the hot air blower, and the air outlet of the hot air blower is arranged toward the heat preservation cover.

[0011] In the above solution, the hot air blower is integrated on the working platform and its hot air is blown out through the set air duct, which effectively ensures that the water seal on the surface of the prefabricated component evaporates quickly and reduces the time for roughening and finishing the prefabricated component in the lower workstation.

[0012] Preferably, the heat preservation cover includes an air guide plate and a curtain. The air guide plate includes an arc-shaped plate extending downward and outward from the support assembly. The curtain is vertically downwardly arranged on both sides of the air guide plate. The air guide plate and the curtain form the air duct. The installation structure and shape of the arc-shaped plate are more conducive to air guidance and heat transfer.

[0013] In order to achieve heat collection, the heat-insulating cover further includes heat-insulating cotton, which is laid on the side of the air guide plate adjacent to the curtain.

[0014] Preferably, the air guide plate further comprises a flat plate extending horizontally from the end of the curved plate away from the support assembly. The flat plate has a flat structure that facilitates contact between the hot air and the prefabricated components to quickly evaporate moisture.

[0015] Preferably, a pull ring is provided on the support assembly, and the pull rings are provided on both the curved plate and the flat plate. The heat preservation cover is fixed by a steel wire rope that passes through the pull ring on the support assembly, the pull ring on the curved plate and the pull ring on the flat plate in sequence.

[0016] According to the stress characteristics of the thermal insulation cover, the position of the pull ring is reasonably arranged, the installation structure is stable, and it is easy to achieve by using a steel wire rope.

[0017] Preferably, the support assembly includes:

[0018] A base frame having at least two suspension points in the Z direction;

[0019] A lifting frame, slidingly coupled to the two lifting points along the base frame;

[0020] A driving member, driving the lifting frame to move up and down along the base frame;

[0021] The mounting frame fixes the hot air blower to the end of the lifting frame, and the hot air blower is lifted and lowered together with the lifting frame under the drive of the driving member.

[0022] Preferably, the working platform is provided with horizontal moving wheels and a sensing device, the horizontal moving wheels are arranged at intervals in the X direction, and the sensing device is electrically connected to the hot air blower.

[0023] The present invention also provides a concrete precast component production line, comprising a table form vehicle for carrying precast components and a conveying track arranged above the table form vehicle, and also comprising the above-mentioned pre-curing device, wherein the working platform reciprocates in the X direction along the conveying track, and the thermal insulation cover is arranged close to the table form vehicle.

[0024] In this solution, the curing device is integrated into the production line, moving in the direction of travel of the precast components and providing heat. This ensures that the precast components are fully heated before leaving the pre-curing station, maximizing the rapid evaporation of surface moisture, thereby reducing processing time at downstream stations. Furthermore, this solution can be adapted to the layout of different factory production lines.

[0025] Preferably, the heat-insulating cover makes the air duct gradually narrow from the support assembly toward the table car, so that the air duct with a variable cross-section is more conducive to the concentration of heating and the increase of hot air flow.

[0026] The present invention also provides a processing method for the above-mentioned precast concrete component production line, comprising:

[0027] 1) The prefabricated components enter the pre-curing station under the transportation of the formwork vehicle;

[0028] 2) After the sensing device senses that a prefabricated component has entered the pre-curing station, the hot air blower and the working platform are activated, so that the pre-curing device moves back and forth along the prefabricated component to heat it;

[0029] During the heating process, the support assembly is started to rise and fall according to the thickness of the prefabricated component to adjust the height of the hot air blower and the heat insulation cover;

[0030] 3) When the prefabricated component leaves the pre-curing station, the sensing device sends a signal to stop the hot air blower and the working platform;

[0031] 4) The above-mentioned actions are repeated until the sensing device senses the entry of the next prefabricated component.

[0032] Compared with the related art, the present invention has the following beneficial effects:

[0033] 1. Improve production efficiency and high reuse rate;

[0034] 2. Improve the efficiency of pre-curing processing and save the working time of the next workstation;

[0035] 3. Improve the curing time and speed up demoulding. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The work platform 11 is provided with horizontal moving wheels 17 that slide along the conveying track 4 , and two groups of the horizontal moving wheels 17 are spaced apart in the X direction. The sensing device 18 is provided on the side of the work platform 11 facing the table vehicle 2 .

[0044] The support assembly 12 includes a base frame 121, a suspension point 122, a lifting frame 123, a drive member 124, and a mounting frame 125.

[0045] The lifting frame 123 slidably engages with the base frame 121 at the two suspension points 122. The driving member 124 is a hoist that connects the base frame 121 and the lifting frame 123. The mounting frame 125 secures the hot air blower 13 to the end of the lifting frame 123. When the driving member 124 is activated, the lifting frame 123, the mounting frame 125, and the hot air blower 13 thereon are moved upward and downward along the base frame 121 (in the Y direction).

[0046] The hot air blower 13 is an outsourced component having a heat disperser and a heating plate.

[0047] The heat preservation cover 15 is fixed on the support assembly 12 and is located next to the hot air blower 13. The air outlet of the hot air blower 13 is arranged toward the heat preservation cover 15.

[0053] During the heating process, the support assembly 12 is started to rise and fall according to the thickness of the prefabricated component 3 to adjust the height of the hot air blower 13 and the heat insulation cover 15.

[0054] 3) When the prefabricated component 3 leaves the pre-curing station, the sensing device 18 sends a signal to stop the hot air blower 13 and the working platform 11.
