Abstract
Stern tube shaft anti-rotation device before a kind of marine shafting connects, comprise positioning plate, be arranged on the adjustment bolt of this positioning plate one end and hook, and be arranged on the latch of the described positioning plate other end, one end overcoat of this latch has sleeve, interior with screw rod phase downlink connection, the other end of this screw rod is provided with packing ring, and installation method.The present invention prevents stern tube shaft from when screw propeller is surprisingly subject to external force, improper rotation occurring and causing the destruction to stern tube shaft and related accessories, have easy and simple to handle, can permanent repeated usage, without the need to special maintenance, cost of manufacture and the relatively low feature of use cost.
Description
Technical field
The present invention relates to marine shafting to 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 is only by 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, thus cause the lower pressure oil pump landing of stern tube shaft bow, form stern tube shaft bow end to upwarp instantaneously, greater impact is caused to 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 region, screw propeller unintentional rotation may cause the injures and deaths of related personnel.Once there is such event, consequence is extremely serious, and with regard to axle system, shipowner can require the inspection that lies up, and so, not only can cause great economic loss, also greatly can 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, stern tube shaft anti-rotation device and installation method thereof before providing a kind of marine shafting to connect, avoid the unintentional rotation of stern tube shaft, ensure the product design of axle system to 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, feature is that its formation comprises positioning plate, is arranged on the adjustment bolt of this positioning plate one end and hook, and be arranged on the latch of the described positioning plate other end, one end overcoat of this latch has sleeve, interior with 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, comprises the steps:
After the first step, launching, channel-section steel cutter is fixed in stern tube shaft front end to remove, the two longitudinal channel-section steels only retaining a transverse channel steels above stern tube shaft rear end and weld with it;
Second step, adjust the right position of stern tube shaft, then directly over stern tube shaft flange, apply 5 ton forces vertically downward with an oil pump;
3rd step, by about stern tube shaft flange two lateral opening clean clean, then by the sleeve load hole of stern tube shaft anti-rotation device;
4th step, by latch by inserting in sleeve after the pin hole of positioning plate;
5th step, screw adjustment bolt until adjustment bolt head withstand channel-section steel, then tightening nut;
6th step, wooden unit is utilized to be padded in the gap between positioning plate and channel-section steel;
7th step, screw rod is fixing by be screwed into after packing ring in latch;
8th step: after shafting alignment, the stern tube shaft anti-rotation device of connection axle series also described in dismounting.
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, avoiding to lie up to release stern tube shaft the risk detecting associated components and repair, and also ensure that manufacturing schedule while ensure that product design.
2, drop into, use and maintenance expense lower, be easy to apply
3, be applicable to all kinds of ship type, commonality is comparatively strong, and this just serves significant by this gain effect, meanwhile, and also convenient management;
4, durable in use, constantly can reuse, reach the effect of " once drop into, be benefited all the life ".
