Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of templates, specifically to a template automatic cleaning and oiling intelligent tensioning integrated system. BACKGROUND

[0002] Traditional template cleaning and oiling operations have many drawbacks. On the one hand, manual template cleaning is labor-intensive and inefficient. Due to the subjectivity and inconsistency of manual operation, the cleaning effect is difficult to guarantee, and impurities may remain, affecting the quality of subsequent concrete pouring. On the other hand, in the oiling process, manual application of release agent often results in uneven application, which not only affects the appearance quality of concrete components, but also may cause abnormal bonding between the template and the concrete, increasing the difficulty of template removal, and even damaging the template and concrete components.

[0003] In the process of cleaning the template, the efficiency is low. To solve the above problems, reference can be made to the existing technology (Chinese patent with application number CN202211027668.6 and application date August 25, 2022) disclosed in the bridge tower special template automatic cleaning device. The cleaning device can clean the inner surface of the template along the guide rails installed on both sides of the template by using a walking template cleaning vehicle. After cleaning, it can be turned over to the back to standby without affecting the construction, meeting the continuous operation requirements. The guide rails are consistent with the bending angle of the template, effectively guiding the movement of the walking template cleaning vehicle. Reference can also be made to the existing technology (Chinese patent with application number CN202420422005.2 and application date March 1, 2024) disclosed in a template cleaning device. The device is used for cleaning the template and includes a box body and a lifting assembly arranged in the box body. One side of the box body is provided with a cleaning assembly connected with the lifting assembly. The cleaning assembly includes a rotating drive and a cleaning disc connected with the driving end of the rotating drive. The rotating drive drives the cleaning disc to rotate to clean the template. The lifting assembly drives the cleaning assembly to move linearly towards or away from the template cleaning surface to quickly clean the used template.
