Abstract

The invention discloses a hydraulic multi-axis screwing device for flange bolts. The hydraulic multi-axis screwing device comprises a main frame body and an assistant frame body, and is characterized in that connection seats are arranged on both the main and assistant frame bodies, and can be directly connected with a mechanical arm of an excavator; the main and assistant frame bodies are connected with each other through a plurality of connection oil cylinders and positioning wheels; a plurality of groups of reduction gears and a plurality of hexangular sleeves are arranged in the main frame body; a plurality of hydraulic motors are correspondingly mounted on the outer side of the main frame body; the hexangular sleeves arranged in the main frame body are used for placing of the bolts; a plurality of hexangular sleeves, which are used for placing of the bolts, provided with no without teeth and capable of rotating, are correspondingly arranged in the assistant frame body; through driving of the hydraulic motors, the reduction gear groups and the hexangular sleeves arranged in the main frame body, the bolts can be effectively screwed. The hydraulic multi-axis screwing device is suitable for the work condition of the connection through a bolt which has high screwing torque, simple to manufacture, low in production cost, high in work efficiency and low in labor intensity, and has the advantage that the operating efficiency of a dredger can be improved.

Description

technical field [0001] The invention relates to a flange bolt tightening device, in particular to a hydraulic multi-axis flange bolt tightening device. Background technique [0002] Dredgers and steel pipes are commonly used equipment in reclamation projects in inland rivers, lake areas and coastal ports. The main types of dredgers include cutter suction dredgers and trailing suction dredgers. Existing dredgers usually complete the dredging, mud transporting and unloading work continuously, and their construction time will be affected by factors such as ship machine maintenance, ship dispatch, weather, construction arrangements, pipeline factors, etc., in order to reduce dredging The construction time of the mud ship, reducing the frequency of pipeline replacement and the operating time for each replacement are the most direct and effective means of improvement. [0003] The existing mud discharge pipe pipeline is made of 5.8m, 6m, 11.8m, 12m steel pipes and 3m hoses conne...
