Embodiment 1

[0022] Embodiment one, such as Figure 1 to Figure 4 As shown, the invention discloses a specific implementation of each step of a floating type pipe clamp installation device as follows: the floating type pipe clamp installation device includes a bracket 7, two ends of the bracket 7 are provided with buoyant tanks 6, and between the two buoyant tanks 6 is a tube In the clamp installation work area, the bracket 7 is provided with a pipe fixing rope 3, a pipe clamp adjustment rope 5, and a pipe clamp lifting rope 4 at the pipe clamp installation work area, and each rope is respectively equipped with a hand hoist to adjust the elongation of the rope length.

[0023] Specifically, the support 7 is a steel frame structure, which is welded by two main girders and a number of support beams. The two ends of the support 7 are provided with sub-frames, and the buoyancy tank 6 is installed in the sub-frames. When the water depth of the installation point was greater than 1.5 meters, th...

Embodiment 2

[0029] Embodiment 2, the present invention also discloses a method for installing pipe clamps on damaged pipelines, which is accomplished through the following steps: (1) select the buoyant tank 6 according to the size and weight of the pipeline 1, and make the bracket 7; (2) according to the installation point Determine the size of the pipe fixing rope 3 and the lever block 10 according to the water depth and the size of the pipe clamp installation work area; (3) Make a suitable lifting point according to the weight of the pipe clamp and the predicted traction angle position; (4) According to the installation point The water depth determines the position of the buoyant tank 6; (5) Select the appropriate pipe clamp hoisting rope 4 according to the size and weight of the pipe clamp, adjust the size of the rope 5 and the lever block 10 for the pipe clamp; The card adjustment rope 5 and the pipe fixing rope 3 are respectively assembled with the hand hoist and installed on the lift...

Abstract

The invention discloses a floating type pipe clamp mounting device and a pipe clamp mounting method. The floating type pipe clamp mounting device comprises a support, floating boxes are arranged at the two ends of the bottom face of the support, a pipe clamp mounting operation area is arranged between the floating boxes at the two ends, and pipeline fixing ropes are arranged at the positions, at the front portion and the rear portion of the support, of the pipe clamp mounting operation area; and a pipe clamp hoisting rope is arranged at the position, in the middle of the support, of the pipe clamp mounting operation area, pipe clamp adjusting ropes are arranged at the positions, at the two sides of the pipe clamp mounting operation area, of the support, and lever blocks are arranged on the pipeline fixing ropes, the pipe clamp hoisting rope and the pipe clamp adjusting ropes. The floating type pipe clamp mounting device and the pipe clamp mounting method solve the problems that when a shoal pipeline is repaired, a maintenance ship cannot enter a site, the pipeline is affected by surges, and the pipeline and a pipe clamp are difficult to mount are solved.

Description

technical field [0001] The invention relates to the field of repairing shoal pipelines, in particular to a floating pipe clamp installation device and a pipe clamp installation method. Background technique [0002] During the repair process of the damaged part of the submarine pipeline in the shoal section (water depth of about 1 meter), the following problems often occur during construction due to the shallow water surface near the shore: [0003] 1. It is difficult for general pipe laying and maintenance engineering ships to enter the construction site. If another non-engineering ship is rebuilt for construction, it will take a long time and the cost will be high; [0004] 2. During the installation process, if the overall rotation of the pipe clamp is required, it is difficult to rotate freely; [0005] 3. If the hoisting distance is long, it is necessary to adjust the hoisting range or the position of the ship, which is cumbersome and time-consuming; [0006] 4. When t...
