Example Embodiment

[0022] Example 1, such as Figure 1 to 4 As shown, the present invention discloses a specific implementation of each step of a floating tube mounting device as follows: The floating tube mounting device includes a stent 7, and both ends of the bracket 7 are provided with a floating box 6, and the two floating boxes 6 are tubes. Card mounting work area, bracket 7 on the pipe card installation work area, with pipe fixing rope 3, tube card adjustment rope 5, and tube card hoisting rope 4, and each rope is installed with hand plate hoist to adjust the elongation of the rope length.

[0023] Specifically, the stent 7 is a steel frame structure, which is welded from two main beams and several support beams, and the bracket 7 is provided, and the floating box 6 is mounted in the sub-frame. When the mounting point water depth is greater than 1.5 meters, the floating box 6 and the sub-frame are disposed below the bracket 7; when the mounting point water depth is less than 1.5 meters, the fl...

Example Embodiment

[0029] Embodiment 2, the present invention also discloses a method of mounting a tube card method on a damage to the conduit, and (1) selects a floating box 6, produces a floating box 6, and produces a stent 7; (2) according to mounting points. Water depth and tube card mounting area size, determine the size of the pipe fixing rope 3 and the handle of hoist 10; (3) Creating a suitable lifting point according to the weight of the tube card and the predictive traction angle; (4) according to the mounting point The water depth determines the position of the floating box 6; (5) Select the appropriate pipe card lifting rope 4 according to the tube card size and weight, the tube card adjustment rope 5 and the size of the handlers 10; (6) Lifting the tube card hoisting 4, tube 4 Card adjustment rope 5 and pipe fixing rope 3 separate and hand plate hoist assembly, and installed on a lifting point; (7) Install the tube card on the tube card lifting rope 4, and then damage the pipe 1 drag t...

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...
