Description
Technical Field
The invention relates to the field of hatch covers of cargo holds of barges or small cargo ships, in particular to a retractable hatch cover convenient to open and close.
Background
Due to the advantages of simplicity, economy and capability of installing more oil transfer risers and umbilical systems, the multi-point mooring is more applied to the project of refitting the old oil tanker into the FPSO, and the installation process and the construction sequence of the multi-point mooring are the key points and the difficulties in the whole refitting project.
The VLCC refitting FPSO marine project applied to the product is the project with the largest project amount and the most complex project in the same type of refitting in the world at present. The FPSO is also the offshore floating production and storage device with the most advanced function, and has the full ship length of 338.87m, the profile width of 58m and the profile depth of 31 m. When a thick toggle plate of a cable guide is welded to a ship, the thick toggle plate is easily deformed due to welding heat.
Disclosure of Invention
In order to solve the problems, the invention provides an anti-deformation dummy shaft for installing a cable guide, aiming at achieving the purpose that when a thick toggle plate of the cable guide is welded on a ship, the thick toggle plate cannot be deformed due to welding heat, and the adopted technical scheme is as follows:
an anti-deformation dummy shaft is mounted on a bearing seat of a cable guide, and is provided with a connecting shaft and a shaft cap which are vertically arranged, wherein the connecting shaft is a long round pipe with a hollow inner part, and two ends of the connecting shaft are welded with first connecting flanges; the shaft cap is a hollow round short pipe, a liner plate is welded at one end of the shaft cap, the shaft cap is nested inside a bearing seat, a second connecting flange is welded at one end, away from the liner plate, of the shaft cap, the diameter of the second connecting flange is larger than that of the bearing seat, an end cover is plugged at the end part of the bearing seat, and the end cover is fixedly connected with the liner plate through bolts.
Above-mentioned dummy shaft of preapring for an unfavorable turn of events of chock installation, further, first connecting flange below, along first connecting flange circumference equidistant welding has four brackets.
Above-mentioned chock installation anti-deformation dummy shaft of fairlead, further, the bolt passes first flange, second flange will the axle cap with the connecting axle is connected.
Above-mentioned dummy shaft of preapring for an unfavorable turn of events of chock installation, further, the end cover is circular, and its diameter is greater than the interior circle diameter of chock.
Above-mentioned chock mount of fairlead shape dummy shaft of preapring for an unfavorable turn of events, further, the inner circle diameter of chock is 345 mm.
Above-mentioned chock installation anti-deformation dummy shaft of fairlead, further, the axle cap excircle diameter is 344.7 mm.
The deformation-preventing dummy shaft has a simple structure, and in the whole process of welding the toggle plate, the shaft cap is tightly matched with the inner hole of the bearing seat, so that the deformation caused by heat during welding is effectively controlled, and the concentricity of the upper bearing seat and the lower bearing seat of each group of cable guides can meet the precision requirement. Thus, the subsequent roller pin of the cable guider can be ensured to smoothly penetrate into the upper bearing seat and the lower bearing seat from top to bottom.

Detailed Description
The invention is further explained with reference to the drawings.
An anti-deformation dummy shaft for mounting a bearing seat of a cable guide device is provided with a connecting shaft 1 which is vertically arranged, wherein the connecting shaft is a long round pipe with a hollow inner part, and first connecting flanges 7 are welded at two ends of the connecting shaft. The connecting shaft is also provided with a shaft cap 2 matched with the connecting shaft, the shaft cap is a short round pipe with a hollow inner part, one end of the shaft cap is welded with a lining plate 4, one end of the shaft cap far away from the lining plate is welded with a second connecting flange 8, and the second connecting flange is matched with the first connecting flange to fixedly connect the connecting shaft with the shaft cap. Four toggle plates 3 with reinforcing structures are welded below the first connecting flange at equal intervals along the circumferential direction of the first connecting flange.
One end of the shaft cap with the lining plate is inserted into the bearing seat 6, the diameter of the inner circle of the bearing seat is 345mm, the diameter of the outer circle of the shaft cap is 344.7mm, and the gap between the shaft cap and the inner hole of the bearing seat is 0.3 mm. An end cover 5 is plugged outside the bearing seat and is fixedly connected with the lining plate 4 through a bolt.
When the cable guide device is used, after the connecting shaft, the shaft cap and the bearing seat are connected and fixed, the cable guide device is hoisted to the outer plate of the cable guide device, the bearing seat is welded with the outer plate of the cable guide device until all welding work of the group of cable guide device bearing seats and the outer plate is finished, and the connecting shaft and the shaft cap are detached from the bearing seat for subsequent work.
According to the deformation-preventing dummy shaft, in the whole process of welding the toggle plate, the shaft cap is tightly matched with the inner hole of the bearing seat, so that the deformation caused by heat during welding is effectively controlled, and the concentricity of the upper bearing seat and the lower bearing seat of each group of cable guides can meet the precision requirement. Therefore, the subsequent roller pin of the cable guider can be ensured to smoothly penetrate into the upper bearing seat and the lower bearing seat from top to bottom.
