Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline assembly of ship double-bottom segments, and particularly relates to an auxiliary device for installing pipe tunnel pipe systems. Background Art

[0002] At present, a pipe tunnel cabin is generally arranged in the middle of the double-bottom area of a ship. A large number of pipe systems are arranged in the cabin. Usually, the sectional division method is also disconnected left and right in the pipe tunnel cabin, forming an opening structure of the pipe tunnel cabin. The pipe systems need to be introduced and installed from the opening side.

[0003] At the present stage, after using a truck crane or other crane to hoist the pipe fittings to be installed, construction workers need to use a chain block and cooperate with the crane for installation, and gradually introduce the pipe fittings from the outside into the installation position in the pipe tunnel.

[0004] Based on the above installation method, there are mainly the following problems: (1) It takes a long time to occupy the crane, increasing the sectional outfitting construction period. (2) The operation difficulty for construction workers is large, the process is cumbersome and the safety is low. (3) When using a sling to hoist the pipe system, the sling will rub against the sectional plate edge during the guiding process, reducing the service life of the process equipment. (4) The guiding space for the pipe system is limited. It is necessary to remove the temporary guardrails existing on the free edges of the pipe tunnel area of the double-bottom segment, and restore the guardrails after the pipe system installation is completed. There are problems of repeated erection and dismantling, and the construction safety is reduced. Content of the Utility Model

[0005] The purpose of the utility model is to provide an auxiliary device for installing pipe tunnel pipe systems, which can effectively solve the problems of low assembly efficiency, high sling loss and low construction safety existing in the current installation method of pipe tunnel pipe systems.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] An auxiliary device for installing pipe tunnel pipe systems includes a moving base, a fixing unit for fixing the auxiliary device on the outer bottom plate of the double-bottom segment, and a guiding unit for guiding the pipe system into the pipe tunnel of the double-bottom segment. A tooling access ladder is arranged on one side of the moving base. The tooling access ladder is composed of access steps, tooling railings, an operation platform and operation platform railings. One column is arranged at each of the front and rear two included angles on the other side of the moving base. The guiding unit is welded on the column, and the two columns are connected by a channel steel. The fixing unit is welded on the channel steel.

[0008] The fixing unit includes two fixing plates. The two fixing plates are respectively welded on the upper surface and the lower surface of the channel steel in parallel up and down. Fixing bolts for fixedly connecting the fixing plates and the outer bottom plate are arranged at the free ends of the two fixing plates.

[0009] The guiding unit includes a guiding pipe in an L shape. The vertical pipe section of the guiding pipe is welded to the upper part of the column. The horizontal pipe section of the guiding pipe slopes downward and the angle between it and the horizontal line is 1°. A guiding diagonal brace is connected between the horizontal pipe section of the guiding pipe and the column.

[0010] At each of the four corners at the bottom end of the moving base, a guide wheel is provided. The guide wheel includes a universal guide wheel and a directional guide wheel. The universal guide wheels are provided at two corners on the side of the moving base where the tooling access ladder is located, and the directional guide wheels are provided at two corners on the side of the moving base away from the tooling access ladder.

[0011] Further, the free end of the horizontal pipe section of the guiding pipe bends downward in an arc shape, and the free end of the horizontal pipe section of the guiding pipe is coated with rubber.

[0012] Further, the free end of the vertical pipe section of the guiding pipe bends downward in a semicircular shape.

Detailed implementation manners

[0027] Embodiment 1: An auxiliary device for the installation of pipe tunnels and pipe systems, as Figure 1 shown, includes a square mobile base 1, a fixing unit 2 for fixing the auxiliary device on the outer bottom plate of the double-bottom section, and a guiding unit 3 for guiding the pipe system into the pipe tunnel of the double-bottom section. The mobile base 1 is equipped with a traveling mechanism, enabling the auxiliary device to be conveniently moved to the required installation position. The fixing unit 2 ensures that the auxiliary device does not shift during the operation through the design of the fixing clamp, achieving stable fixation and precise positioning. The guiding unit 3 is responsible for accurately guiding the pipeline to be installed into the pipe tunnel of the double-bottom section, and workers can use a chain hoist for convenient and efficient pipe system installation work.

[0028] Specifically, in this embodiment, a tooling access ladder 5 is provided on the left side of the mobile base 1. The tooling access ladder 5 is composed of access steps, a tooling railing 6, an operation platform 4, and an operation platform railing 7. The operation platform 4 is located at the top of the tooling access ladder 5. The tooling railing 6 is provided on the left side of the access steps and the left side of the operation platform. The operation platform railing 7 is provided at the rear side of the operation platform 4. For the convenience of construction personnel to pass and the safety of construction personnel during operation, therefore, the width of the tooling access ladder 5 is set to 700 mm, the height of the access steps is set to 250 mm, and the height of the tooling railing 6 is set to 1000 mm.

[0029] At both corners at the front and rear ends on the right side of the mobile base 1, a column 8 is provided. Base plates 9 are welded at the four corners of the mobile base 1. The column 8 is fixed on the base plate 9, and the area of the base plate 9 is larger than the bottom end face area of the column 8. The guiding unit 3 is welded on the column 8. The two columns 8 are connected by a channel steel, and the fixing unit 2 is welded on the channel steel.

[0030] As Figure 1 and Figure 3 shown, the fixing unit 2 specifically includes two fixing plates 10. The two fixing plates 10 are respectively welded on the upper surface and the lower surface of the channel steel in parallel up and down. Fixing bolts 11 for fixedly connecting the fixing plate 10 and the outer bottom plate are provided at the free ends of the two fixing plates 10. In this embodiment, the installation of the fixing unit 2 takes into account the segmented support height and matches the height of the outer bottom plate, ensuring that the auxiliary device will not shift or shake during operation. The thickness of the outer bottom plate is usually 22 mm. Considering the deviation of the segmented support height, therefore, the vertical distance between the two fixing plates 10 of the fixing unit 2 in this embodiment is 60 mm, and 8 fixing bolts 11 are used for fastening.

[0031] The guiding unit 3 includes a guiding pipe 12 in an L shape. The vertical pipe section of the guiding pipe 12 is welded to the upper part of the column 8. The horizontal pipe section of the guiding pipe 12 is inclined downward and the included angle between it and the horizontal line is 1°, so that the pipeline can roll into the pipe tunnel cabin. A guiding diagonal brace 13 is connected between the horizontal pipe section of the guiding pipe 12 and the column 8 to increase the strength of the guiding pipe 12. In this embodiment, the free end of the horizontal pipe section of the guiding pipe 12 is bent downward in an arc shape, and the free end of the horizontal pipe section of the guiding pipe 12 is covered with rubber; the free end of the vertical pipe section of the guiding pipe 12 is bent downward in a semicircular shape. There is a certain bending arc at the connection of the vertical pipe section and the horizontal pipe section of the guiding pipe 12.

[0032] As Figure 1 and Figure 2 shown, the moving base 1 has to bear the weight of the entire auxiliary device and the pipeline to be installed and ensure the mobility of the auxiliary device. Therefore, a guide wheel is provided at each of the four corners at the bottom end of the moving base 1, and at the same time, two support columns 14 are provided at the bottom of the front and rear ends of the moving base 1 respectively. The guide wheels include a universal guide wheel 15 and a directional guide wheel 16. The universal guide wheels 15 are provided at two corners on the left side of the moving base 1, and the directional guide wheels 16 are provided at two corners on the right side of the moving base 1. Further, to increase the structural strength of the moving base 1, reinforcing ribs are provided between the respective frames of the moving base 1.

[0033] The main process steps of the present utility model are as follows: (1) Data preparation: Obtain the pipeline layout data inside the double-bottom segment from the ship design drawings, including information such as the size, shape, and position of the pipeline. Check whether the auxiliary device in Embodiment 1 is intact, and ensure that the moving base 1, the fixing unit 2, and the guiding unit 3 can all work normally. Two auxiliary devices are used for cooperative installation of the pipeline.

[0034] (2) Positioning of the moving base 1: Move the auxiliary device to a suitable position of the double-bottom segment through the moving base 1, and position the moving base 1 to the starting position according to the pipeline layout data.

[0035] (3) Use of the fixing unit 2: Clamp two fixing plates 10 on the outer bottom plate, and apply appropriate clamping force through the fixing bolts 11 so that the auxiliary device is firmly fixed on the double-bottom section.

[0036] (4) As Figure 4 shown, use a crane to place the pipeline on the guiding pipe 12, use the crane to protect the pipeline, and the construction workers stand on the operation platform 4 to monitor the pipeline. As Figure 5 shown, when the pipeline is in place, remove the auxiliary device, and another group of construction workers use the ship's eyebolt on the section to take root and use a manual hoist to adjust the pipeline to the pipeline installation position.

[0037] (5) After completing the assembly of one pipeline, move the auxiliary device to the next assembly position to be assembled through the moving base 1. Repeat the above steps of pipeline positioning and fixing until the pipeline assembly work within the entire double-bottom section is completed.

[0038] Compared with the traditional installation method, the utility model greatly reduces the time and labor intensity of manual operation and improves the efficiency of pipeline assembly.

[0039] In the utility model, the pipeline is hoisted onto the guiding unit 3 by using a crane. Due to the slope of the guiding unit 3, the pipeline can slowly move to the assembly position, greatly saving the factory area resources. In addition, the utility model sends the pipe system into the pipe tunnel cabin from a high place, avoiding the area where the guardrail is erected and avoiding the repeated erection and dismantling of the guardrail. The utility model can also avoid the situation that the sling rubs against the edge of the plate and reduce the loss amount of the sling.

[0040] The utility model can be extended for use. For pipelines similar to those at large opening positions, different types of auxiliary devices can be designed according to the height to facilitate the installation of the pipelines.

[0041] Of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the utility model should also fall within the protection scope of the utility model.
