Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement pole technology, specifically to a tooling for cleaning the inner wall of a cement pole mold. Background Technology
[0002] The molds used to produce cement poles are steel molds. The production process follows this sequence: wire drawing, cage weaving, concrete placement, mold closing, tensioning, centrifugal molding, steam protection, and demolding. Existing technology means that solidified concrete adheres to the inner wall of the used pipe pile mold, leading to dents and even cracks on the surface of subsequently produced cement poles, affecting their quality. After demolding, manual cleaning of the mold is usually required. However, the molds are generally large and semi-circular, resulting in high labor intensity, difficulty, and low efficiency. Furthermore, the tightly adhered concrete inside the pipe pile mold is difficult to remove completely. Existing cleaning devices typically use wire brushes, which can only slowly grind the solidified concrete, resulting in low efficiency and insignificant cleaning effects when dealing with large concrete blocks. Therefore, we propose a tooling for cleaning the inner wall of cement pole molds. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This cleaning fixture for the inner wall of cement pole mold has the following advantages:
[0013] 1. By using the rotating metal brush driven by the second motor in the cleaning assembly and the lifting and lowering adjustment of the first electric telescopic rod, combined with the linkage structure of the sprocket ring and chain in the conveying assembly, the inner wall of the mold can be automatically cleaned and continuously conveyed in all directions. In the impact assembly, the cam driven by the fifth motor strikes the slide bar at high frequency, combined with the spring reset action, which can quickly shake off large pieces of concrete residue, significantly improving cleaning efficiency.
[0014] 2. The adjustment component uses a third motor to drive a bidirectional screw to synchronously adjust the spacing of the moving strips. The limit rod ensures the stability of movement, allowing the conveyor wheel set to be adapted to molds of different diameters. In the cleaning component, the first motor, through the precise cooperation of the threaded column and the guide bar, can accurately control the lateral insertion depth of the metal bristles. Combined with the longitudinal stroke adjustment of the first electric telescopic rod, it can achieve flexible control of cleaning pressure and coverage area to meet diverse cleaning needs.
[0015] 3. The anti-slip fastening plate is driven by the third electric telescopic rod to clamp and fix the outer wall of the mold. Combined with the rigid load-bearing structure of the support bar, it effectively suppresses the displacement of the mold during the cleaning process. The periodic vibration impact of the impact component and the rotating cleaning of the metal bristles work together to remove stubborn scale while avoiding mold damage caused by traditional manual knocking, thus balancing the cleaning effect and equipment safety.
