Abstract
A device capable of preventing rotation in connection between ship shafting and a front screw shaft comprises a limit plate, an adjusting bolt arranged at one end of the limit plate, a hook and a bolt arranged at the other end of the limit plate. A sleeve is sleeved on the outside of one end of the bolt, the inside of the bolt is connected with a screw, and a washer is arranged at the other end of the screw. An installing method of the device is further provided. The device can prevent damage to the screw shaft and relevant accessories, and the damage is caused by abnormal rotation caused under the condition that a propeller of the screw shaft is accidentally subjected to external force and has the advantages of being convenient to operate, capable of being used repeatedly and permanently, free of maintaining, low in manufacture cost and low in use cost.
Description
Technical field
The present invention relates to marine shafting and build, particularly a kind of marine shafting connects front stern tube shaft anti-rotation device and installation method thereof.
Background technology
After launching, in the shafting alignment process of carrying out before coupling of shaft system, stern tube shaft bow flange upper end only is subject to 5 ton force effects vertically downward.When extraneous water impact is larger (such as adjacent berth boats and ships carry out main engine bollard test), screw propeller can be subject to an impulsive force and twisting resistance, thereby cause the lower pressure oil pump landing of stern tube shaft bow, forming stern tube shaft bow end moment upwarps, greater impact is caused in the stern tube bearing top, simultaneously, stern tube shaft can produce eccentric irregular rotation, these can cause the damage sealed before and after stern tube shaft, stern tube bearing and stern tube shaft, in addition, if there is water surface operation in ship stern zone, the screw propeller unintentional rotation may cause related personnel's injures and deaths.Once such event occurs, consequence is extremely serious, and with regard to axle system, the shipowner can require the inspection that lies up, and so, not only can cause huge economic loss, also can greatly delay the construction progress of boats and ships.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of marine shafting to connect front stern tube shaft anti-rotation device and installation method thereof, avoid the unintentional rotation of stern tube shaft, the product design of assurance axle system, reduce the security risk of field operation.
Technical solution of the present invention is as follows:
Stern tube shaft anti-rotation device before a kind of marine shafting connects, characteristics are that its formation comprises positioning plate, is arranged on adjustment bolt and the hook of this positioning plate one end, and the latch that is arranged on the described positioning plate other end, one end overcoat of this latch has sleeve, interior and screw rod phase downlink connection, and the other end of this screw rod is provided with packing ring.
Before described marine shafting connects, the installation method of stern tube shaft anti-rotation device, comprise the steps:
After the first step, launching by the stern tube shaft front end fixedly channel-section steel with cutter, remove, only retain stern tube shaft rear end top a transverse channel steels and with two vertical channel-section steels of its welding;
Second step, the position, left and right of adjusting stern tube shaft then apply 5 ton forces vertically downward with an oil pump directly over the stern tube shaft flange;
The 3rd step, two of stern tube shaft flange left and right is lateral opening clean clean, then by the sleeve load hole of stern tube shaft anti-rotation device;
The 4th step, by latch by inserting after the pin hole of positioning plate in sleeve;
The 5th step, screw and adjust bolt and withstand channel-section steel until adjust the head of bolt, then screw nut;
The 6th step, utilize wooden unit that the gap between positioning plate and channel-section steel is padded;
The 7th step, screw rod is screwed into after by packing ring in latch fixing;
The 8th step: after shafting alignment, connection axle series is also removed described stern tube shaft anti-rotation device.
Compared with prior art, beneficial effect of the present invention:
1, can prevent the unintentional rotation of stern tube shaft and cause the damage of stern tube shaft and related accessories, having avoided the risk that need lie up stern tube shaft is released associated components is detected and repairs, also having guaranteed manufacturing schedule when having guaranteed product design.
2, drop into, use and the maintenance expense lower, be easy to apply
3, be applicable to all kinds of ship types, commonality is stronger, and this has just played significantly this gain effect, simultaneously, and also convenient management;
4, durable in use, can constantly reuse, reach the effect of " once dropping into lifelong being benefited ".
