Through a fitted tapered block which can support two guide rollers and an adjustable wedge block which can press two guide rollers. Two guide rollers can achieve relaxation and compression of the guide edge. Further, such a structure may preferably support two sliding blocks, effectively increase the contact area, and avoid free space between the two sliding blocks, i.e. two tapered blocks can play an important supporting role between two sliding blocks. Thus, at the moment of failure, the force of gravity of the cleaning and maintenance device can be transmitted to its convexity on the lower surface of the guide edge from the upper sliding block so that the tension of the entire device is reinforced. The stepping and crushing motor can be stepped and compressed through the fitted disconnecting device. The total weight of the device decreases and the price decreases. In the belt drive mode associated with the power of the stepping belt wheel, the shaft coupled to the top sliding block has a floating degree down to the bottom where the electrical connection can easily reproduce the small range of motion of the sliding block. All equipment has a simple and robust structure, cheap price and reliable operation. Thus, it can change the maintenance manual within certain limits and spray water into steel structures in the remote area.
