Description
Technical Field
The utility model relates to a shipbuilding and ship design field, concretely relates to novel boats and ships rudder button resin sleeve is fixed device.
Background
Usually, the connecting parts of the rudder stock and the rudder pintle with the rudder horn and the rudder button are provided with stainless steel sleeves, and the rudder button is provided with a resin bushing made of high molecular wear-resistant materials. The specific process is that after the rudder stock and the rudder pintle are processed, a stainless steel sleeve is installed at the position of connecting the rudder button in a drying mode. After the rudder system is subjected to stay wire inspection, a group of datum points are respectively made on the end surfaces of the upper rudder button and the lower rudder button, and the inner holes of the upper rudder button and the lower rudder button and the upper end surface and the lower end surface of the upper rudder button and the lower rudder button are aligned according to the datum points. And issuing a rudder button bushing machining size calculation book and machining the rudder button bushing according to the size data of the finished rudder button inner hole, the rudder stock and the rudder pintle. The bush is in interference fit with the rudder button hole, and liquid nitrogen freezing installation is adopted. In order to prevent the axial play of the rudder button bushing, the bushing needs to be fixed to the rudder button or the rudder horn.
Chinese patent No.: 201220124952.0 discloses a connecting device of a fixed rudder stock or rudder pintle and a rudder horn, but it has the following disadvantages:
1. because the accurate position in actual bush center just can be confirmed to upper and lower shrouding after the bush cold charge, so upper and lower shrouding and rudder button can not be at the internal field and drill and tap. If carry out the construction on the ship, the magnetic drill weight of carrying out the drilling tapping is very big, especially when shrouding screw hole under the processing, because the process face is down, the magnetic force of magnetic drill can not bear the gravity of oneself sometimes and carry out work, drops easily for the construction is very difficult and there is considerable potential safety hazard.
2. When a ship runs, if the rudder button bushing rotates in the rudder button, if the rudder button bushing is not found to be solved in time, the abrasion of the rudder button bushing can be caused in a short time, and the safe running of a ship rudder system is seriously influenced. The upper and lower shrouding of design usually does not have the observation hole, and during the operation of boats and ships was maintained, can't confirm whether resin bush can produce the rotation, has very big potential safety hazard.
Disclosure of Invention
In order to solve the above problems, the utility model provides a novel boats and ships rudder button bush is fixed device aims at reaching and eliminates the potential safety hazard, can inspect at any time whether the bush takes place to rotate in the rudder button to guarantee the purpose of boats and ships rudder system safety, its technical scheme who adopts is:
a novel fixing device for a rudder button bushing of a ship comprises a rudder button, a rudder stock or a rudder pintle, wherein a white steel sleeve is sleeved outside the rudder stock or the rudder pintle, a rudder button bushing is arranged in a rudder button hole of the rudder button, an upper sealing plate is arranged at the top end of the rudder button bushing and the joint of the rudder button bushing and a rudder button main body, a lower sealing plate is arranged at the bottom end of the rudder button bushing and the joint of the rudder button bushing and the rudder button main body, the upper sealing plate and the lower sealing plate are connected with the rudder button main body in a welding manner, and the rudder button bushing are sleeved between the upper sealing plate and the lower sealing plate; go up the shrouding down the shrouding surface is opened there are first observation hole and second observation hole, go up shrouding, lower shrouding with rudder button main part welding back, first observation hole site in rudder button bush department, the second is observed the hole site in rudder button main part department, first observation hole with be provided with the mark in the second observation hole. And one part of the upper sealing plate and one part of the lower sealing plate are fixedly connected with the rudder button main body, and the other part of the upper sealing plate and the lower sealing plate are fixedly connected with the rudder button bushing.
Above-mentioned novel boats and ships rudder button bush fixing device, further, go up the shrouding down the shrouding with rudder button main part stage welded connection. The defects of high difficulty in drilling and tapping on site and potential safety hazard are overcome by adopting stage welding; in addition, the reason why the step welding is adopted is that if the full welding mode is adopted, the phenomenon of cracking of the upper sealing plate and the lower sealing plate after welding is generated.
In the novel fixing device for the ship rudder button bushing, further, the mark is a steel seal. The steel seal is punched in the observation hole, so that when the ship is operated and maintained, whether the rudder button bushing rotates in the rudder button can be checked through the observation hole at any time, and the safety of a ship rudder system is ensured.
Above-mentioned novel boats and ships rudder button bush fixing device, further, go up the shrouding, the shrouding is circular down.
The utility model discloses a rudder button, rudderstock structure compares the conventional design form with the bolt fastening, and construction convenience, safety have avoided in shipboard work progress, and the magnetic drill drops easily, leads to the problem of incident, can observe rudder button bush state at any time, maintains the bush, avoids the incident to take place, improves factor of safety.
