Description

technical field [0001] The invention relates to a gate grinding device in water conservancy projects, in particular to a synchronous profiling grinding machine for anti-arc gate steel water stop. Background technique [0002] The anti-arc door in water conservancy projects is opened and closed by rotating around the center of the hinge. During the construction of the anti-arc door steel water-stop repair, the joint surface of the anti-arc door steel water-stop due to cavitation, jet flow and sand erosion pitting. At present, the repair work is completed by manual grinding after manual surfacing. When the anti-arc door is closed, it is difficult to ensure the curve fit between the anti-arc door bottom water stop plate and the sill bottom water stop belt, and the construction labor intensity is high. The quality is poor, the efficiency is low, and the safety risk of construction personnel is high. [0003] Chinese patent "200910061805.6" discloses a synchronous profiling gri...

Problems solved by technology

At present, the repair work is completed by manual grinding after manual surfacing. When the anti-arc door is closed, it is difficult to ensure the curve fit between the anti-arc door bottom water stop plate and the sill water stop belt, and the construction labor intensity is high. Poor quality, low efficiency, and high safety risks for construction workers

[0003] Chinese patent "200910061805.6" discloses a gate synchronous profiling grinding machine, which can be mechanically repaired by profiling, which reduces labor intensity and improves repair accuracy, but there are problems: 1) because the bottom sill cannot be damaged Embedded metal plate, track installation is more complicated, the track is adsorbed on the bottom sill embedded metal plate through the suction cup, if the force is uneven or there is a large lateral force during repair, the track is prone to displacement, which will affect the repair accuracy

[0004] 2) The repair process is open-loop control, and the machining accuracy is not easy to guarantee

[0005] 3) The adjustment of the profiling head adopts mechanical adjustment, which is not conducive to the use of digital control

[0006] 4) The rigidity of the door frame is not enough, it is easy to deform during the repair process and affect the repair accuracy

[0007] 5) The accuracy of the sill curve obtained by the guide wheel is low, and the error of profiling repair is relatively large
