Technical Field

[0001] This invention relates to the field of precast concrete curing technology, specifically to a precast concrete curing device. Background Technology

[0002] During the fabrication of precast concrete components, multiple water spraying curing treatments are required to prevent subsequent cracking. These precast concrete components include precast cover plates (i.e., cement covers for cable trenches), utility poles, and other concrete products. Referring to Chinese patent publication number CN117507119B, "A Precast Concrete Component Curing Device," this patent points out that existing water curing methods struggle to evenly spray water onto the inner walls of precast concrete components, leading to uneven water absorption and increasing the risk of cracking during curing. However, this equipment still suffers from cumbersome curing methods and low efficiency. Therefore, we propose a precast concrete component curing device to address these issues. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a precast concrete component maintenance device, which solves the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a precast concrete component maintenance device, comprising a body, a bottom sealing plate fixedly installed at the bottom of the body, a middle partition fixedly installed in the middle of the inner side of the body, and multiple bearing rods provided between the middle partition and the inner sides of the body, wherein a precast concrete component is placed on top of the bearing rods;

Multiple atomizing nozzles are fixedly installed on the outside of the I-shaped spray frame. A negative pressure pump that is interconnected is installed on the top of the I-shaped spray frame. The liquid inlet of the negative pressure pump is connected to a liquid extraction pipe. The end of the liquid extraction pipe is connected to the bottom inside the machine body to extract the spray water stored inside the machine body and spray it onto the precast concrete component through the cooperation of the I-shaped spray frame and the atomizing nozzles.

[0006] The middle partition is equipped with a drive assembly for driving the I-shaped spray frame to slide back and forth inside the arc-shaped slot.

[0007] Preferably, the drive assembly includes a servo motor, and drive shafts are rotatably connected to both sides of the inner part of the middle partition, and drive chains are rotatably connected to the outer side of the drive shafts. A limiting sleeve is rotatably sleeved on the outer side of the I-shaped spray frame, and the limiting sleeve is fixedly connected to one side of the inner part of the drive chain, for driving the I-shaped spray frame to slide inside the arc-shaped groove as the drive chain runs.

[0008] Preferably, a positioning plate is fixedly installed at the bottom of the negative pressure pump, and the positioning plate is fixedly connected to the I-shaped spray frame.

[0009] Preferably, an extension frame is fixedly installed on both sides of the interior of the I-shaped spray frame, and the extension frame is connected to the I-shaped spray frame and has multiple atomizing nozzles fixed on the side close to the precast concrete component.

[0010] Preferably, a heating tube is fixedly installed on the top surface of the bottom sealing plate for heating the spray water, and a liquid level monitor is fixedly installed on the inner side of the machine body.

[0011] Preferably, a control panel is fixedly installed on the outside of the machine body.

[0012] Preferably, an arc-shaped support frame is fixedly installed on the inner side of the machine body and the outer side of the middle partition, and a sliding end is slidably connected inside the arc-shaped support frame. A positioning bolt is installed at the bottom of the sliding end to lock the sliding end into the arc-shaped support frame. The two ends of the bearing rod are rotatably connected to the inside of the corresponding sliding end.

[0015] Preferably, a protective cover is fixedly installed at the end of the machine body, and a heat insulation sheet is wound inside the protective cover to block the top of the machine body. A pull rod is fixedly installed at the end of the heat insulation sheet.

[0016] This invention provides a device for precast concrete component maintenance. Compared with the prior art, it has the following advantages:

[0017] (1) The precast concrete component maintenance device, through the setting of the I-shaped spray frame, when the precast concrete component is placed, the spray frame and the atomizing nozzle reciprocate inside the middle partition frame, which can extract the spray water and spray it onto the surface of the precast concrete component through the atomizing nozzle, thereby increasing the spray range of the equipment. Compared with the traditional maintenance method, it can further improve the spray uniformity and spray convenience, is suitable for batch operation, reduces manual intervention, and can be applied to spray treatment of precast concrete components of different shapes and sizes, thus improving the applicability of the equipment.

[0018] (2) The precast concrete component maintenance device, through the setting of the bearing rod, can drive multiple bearing rods to rotate when spraying precast concrete components with a column shape for maintenance, so that the precast concrete components with a column shape can rotate with the bearing rods until the spraying process is completed. This can reduce the number of unsprayed parts on the surface of the precast concrete components during the spraying process, and further improve the maintenance effect of the equipment. At the same time, through the setting of the heat insulation plate, the top of the machine body can be blocked during the spraying maintenance process, further ensuring the maintenance effect.
