At present, technicians at home and abroad are dedicated to research and develop various detection and operation devices for underwater large-scale piles and make certain progress, but the existing detection and operation devices for underwater large-scale piles still have many defects, which are mainly reflected in the following aspects:
(1) the existing underwater large-scale pile detection and operation devices mostly adopt a gear transmission mode, however, aiming at large-scale piles, the problems of difficult processing, high cost, large quality and the like of gears with large reference circle diameters exist; meanwhile, the gear with the large reference circle diameter is necessarily matched with the large module, and the gear transmission with the large module necessarily leads to lower transmission precision and positioning precision, so that the detection precision and the operation precision are lower, and the actual application requirements cannot be well met.
(2) The existing underwater large-scale pile detection and operation device usually adopts a slide rail type rotation mode, however, aiming at large-scale piles, the problems of difficult processing, high precision requirement, high processing cost and the like of large-diameter slide rails exist; meanwhile, the sliding rail has the problems of large rotation resistance, easy corrosion, easy blockage and the like under the operating environment with multiple impurities and high corrosion.
(3) The detection and operation function module carried by the existing underwater large-scale pile detection and operation device is usually fixed, so that the detection and operation function module only aims at a certain size of pile and has detection and operation capacity, and the application field and the application range of the detection and operation device are severely limited.
