Abstract

A transportation platform for an underwater towing device, including: a main frame; a support frame; a movable base; operation decks; ladder stands; and main lifting lugs. The main frame includes upright posts, basal tubes, longitudinal tubes, transverse tubes, and diagonal tubes. The support frame includes cushion blocks, transverse beams, stand columns, carrier bars, and stiffeners. The ladder stands include stand pipes and a plurality of deformed bar. The main lifting lugs are disposed on the upright posts of the main frame. The support frame is in the form of a door frame and disposed in the lower part of the main frame. The carrier bars cross over the basal tubes. The stiffeners are disposed between the upright posts of the main frame and the transverse beams. The cushion blocks are disposed on the carrier bars. The movable base is disposed between the carrier bars of the support frame.

First claim

The invention claimed is:

1. A transportation platform for an underwater towing device, the transportation platform comprising:
a main frame, the main frame comprising upright posts, basal tubes, longitudinal tubes, transverse tubes, and diagonal tubes;
a support frame, the support frame comprising cushion blocks, transverse beams, stand columns, carrier bars, and stiffeners;
a movable base;
operation decks;
ladder stands, the ladder stands comprising stand pipes and a plurality of bars; and
main lifting lugs;

wherein:
the main lifting lugs are disposed on the upright posts of the main frame;
the support frame is disposed in a lower part of the main frame;
the carrier bars cross over the basal tubes; the stiffeners are disposed between the upright posts of the main frame and the transverse beams;
the cushion blocks are disposed on the carrier bars;
one end of the stand columns is connected to the carrier bars, and the other end thereof is connected to the transverse beams;
the movable base is disposed between the carrier bars of the support frame, and is connected to the support frame via chains;
the operation decks are in the form of a stiffened plate, and are disposed on the upright posts of the main frame; the longitudinal tubes are located at an outer side of the operation decks; and handrails are disposed on the upright posts and above the operation decks; and
the ladder stands are disposed at two sides of the main frame.

2. The platform of claim 1 , wherein the movable base comprises arc pads, concave clampers, first lifting lugs, horizontal tubes, a plurality of longitudinal bars, and square legs; the plurality of longitudinal bars is disposed between and perpendicular to the horizontal tubes; the arc pads and the concave clampers are disposed on the horizontal tubes, and the arc pads are clamped in the concave clampers; the first lifting lugs are disposed at two ends of the horizontal tubes; and the square legs are disposed at four bottom corners of the movable base.

3. The platform of claim 2 , further comprising a movable brace rod which is disposed at an upper opening of the main frame, wherein inner sides of the upright posts are provided with concave holders, and the movable brace rod is supported by the concave holders.

4. The platform of claim 3 , wherein the upright posts, the movable brace rod, the carrier bars, the stand pipes, the square legs, the plurality of longitudinal bars, and the horizontal tubes employ square tubes.

5. The platform of claim 2 , wherein the stiffeners are made of angle steel, the transverse beams and the stand columns are made of channel steel; inner sides of the stand columns are provided with second lifting lugs; and the second lifting lugs are connected to the first lifting lugs via the chains.

6. The platform of claim 1 , wherein the longitudinal tubes on an upper part of the main frame are provided with fourth lifting lugs which are symmetrically distributed.

7. A method for using the transportation platform for an underwater towing device of claim 1 , the method comprising:
1) removing a movable brace rod disposed at an upper opening of the main frame;
2) employing a truck crane to install a main body of a towing device in an upper part of the transportation platform, installing a lower part of the towing device on the movable base of the transportation platform, and moving the movable base in its movable range that is allowed by the chains connecting the movable base to the support frame to fix the main body on the lower part of the towing device;
3) mounting the movable brace rod in concave holders of the upright posts;
4) connecting a top of the towing device and fourth lifting lugs of the longitudinal tubes using cables;
5) hoisting and transferring the transportation platform and the towing device using the truck crane to a tug boat; and
6) transporting the transportation platform and the towing device to a destination, and unloading the towing device out of the transportation platform.
