Description

Technical Field

[0001] The invention relates to the field of preinstallation of electrical equipment on ships, and in particular to a method for preinstallation of electrical equipment on ships. Background Art

[0002] During the shipbuilding process, it is common to encounter the problem that the delivery time of electrical equipment is later than the hull assembly node time, at which time the hull has been sealed. Since the electrical equipment is large in size and heavy in weight, a large number of people are required to carry and shift it in the room after sealing without the cooperation of a crane. The current installation method is: first move the electrical equipment to the equipment base, then draw bolt holes on the equipment base and back support, and then lift the equipment down. After the bolt holes on the equipment base and back support are drilled, lift the equipment onto the base for installation. However, there is a problem of secondary installation in this installation process. The equipment is completely transported by manpower during the two times of transporting, which is too long. It not only consumes manpower and material resources and has low efficiency, but also has high risks during the transportation process and high labor intensity for workers. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the related art, an object of the present invention is to provide a method for pre-installing ship electrical equipment, so as to avoid the problem of secondary installation of the electrical equipment.

[0004] In order to achieve the above-mentioned object and other related objects, the present invention provides a method for pre-installing ship electrical equipment, the method comprising the steps of:

[0005] Make equipment simulation tooling based on the appearance of the electrical equipment to be installed;

[0006] Make bottom tooling and back support tooling, and install the bottom tooling and back support tooling on the equipment simulation tooling;

[0007] Position the equipment simulation tooling on the base on the ground, and drill holes on the base and the back support seat on the bulkhead based on the bottom tooling and the back support tooling to fix the equipment simulation tooling;

[0008] Make fixed wiring tooling, install the fixed wiring tooling on the equipment simulation tooling, and cut the length of the cable connecting the electrical equipment based on the position of the fixed wiring tooling;

[0009] Make pipeline tooling, install the pipeline tooling on the equipment simulation tooling, and lay pipelines based on the pipeline tooling;

[0010] Install electrical equipment.

[0011] Optionally, the steps of making the equipment simulation tooling are: using multiple steel pipes with different specifications and forming a rectangular frame structure according to the length, width and height of the electrical equipment, and three interconnected steel pipes are fully welded and fixed.

[0012] Optionally, the bottom tooling and the back support tooling both include connecting parts and supporting parts, and the connecting parts are respectively installed on the bottom and back of the equipment simulation tooling, and the supporting parts are respectively installed on each connecting part.

[0013] Optionally, the support member is provided with a through hole, and mounting holes are drilled on the base and the back support based on the through hole on each support member. After the mounting holes are drilled, the equipment simulation tooling is fixed to the base and the back support with bolts.

[0014] Optionally, the step of positioning the equipment simulation tooling on a base on the ground is: determine the center lines of the bottom and back of the equipment simulation tooling, place the equipment simulation tooling on the base, make the center line of the bottom of the equipment simulation tooling coincide with the center line of the base, and make the center line of the back of the equipment simulation tooling coincide with the center line of the back support seat.

[0015] Optionally, the fixed wiring tooling includes a support plate and a drawing. The support plate is laid on the equipment simulation tooling, the equipment interface is printed on the drawing, and the drawing is positioned on the support plate, and the cable is cut based on the position of the equipment interface on the drawing.

[0016] Optionally, the pipeline tooling is made and installed on the equipment simulation tooling, and the step of laying the pipeline based on the pipeline tooling is as follows: a connecting hole is opened on the pipeline tooling based on the diameter of the pipeline, and the pipeline tooling is installed on the equipment simulation tooling based on the installation position size of the pipeline, so that the position of the connecting hole corresponds to the installation position of the pipeline, and after the installation of the pipeline tooling is completed, the pipeline is installed and laid out in advance.

[0017] Optionally, the steps of installing the electrical equipment are: lift the equipment simulation tooling from the base, move the electrical equipment to the base for positioning and installation, make the electrical equipment correspond to the mounting holes on the back support and the base and fasten them with bolts, then connect the cable to the corresponding interface on the electrical equipment, and connect the pre-laid pipeline to the electrical equipment.

[0018] As described above, the ship electrical equipment preinstallation method of the present invention has the following beneficial effects: the equipment simulation tooling can be made using on-site surplus materials, and then combined with the equipment appearance design simulation tooling, which greatly reduces the cost investment and positioning error. Each template used in this method has the characteristics of being replaceable and highly adaptable. While ensuring fast installation, it can be accurately adjusted during the installation process, and can highly restore the various dimensions of the equipment, turning the secondary installation into a single installation, improving the construction efficiency, reducing the workload of the construction personnel, and reducing the construction cost.

[0027] In the context of the present application, a structure in which a first feature is described as being "above" a second feature may include embodiments in which the first and second features are formed in direct contact, and may also include embodiments in which additional features are formed between the first and second features, such that the first and second features may not be in direct contact.

[0028] It should be noted that the illustrations provided in this embodiment are only used to illustrate the basic concept of the present invention in a schematic manner, and therefore the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0029] like Figures 1 to 3 As shown, this embodiment provides a method for preinstalling ship electrical equipment. By adopting this method, the preinstallation of cables and pipelines can be achieved, avoiding the secondary transportation of electrical equipment.

[0030] The steps of the method for pre-installing ship electrical equipment include:

[0031] S1. Produce equipment simulation tooling 1 based on the appearance of the electrical equipment to be installed.

[0032] Specifically, the equipment simulation tooling 1 is designed and manufactured in the same size according to the length, width and height of the appearance of the electrical equipment. In the present embodiment, a plurality of steel pipes with different specifications are used to form a rectangular frame structure according to the length, width and height of the electrical equipment. For example, the number of steel pipes is 12, and there are three specifications of steel pipes in the 12 steel pipes, and the steel pipes of each specification only differ in length. In the rectangular frame, the three interconnected steel pipes located at the end corners are fully welded and fixed. In order to enhance the firmness of the equipment simulation tooling 1, a triangle plate is set at the intersection of the three steel pipes for reinforcement. By setting the equipment simulation tooling 1 as a frame structure, not only the manufacturing cost of the equipment simulation tooling 1 can be reduced, but also the weight of the equipment simulation tooling 1 can be reduced for easy handling.

[0033] S2. Make a bottom tooling and a back support tooling, and install the bottom tooling and the back support tooling on the equipment simulation tooling 1.

[0034] In this embodiment, both the bottom tooling and the back support tooling include a connector 2 and a support 3. The connector 2 is installed at the bottom and back of the equipment simulation tooling 1, and the support 3 is installed on each connector 2. Specifically, the back of the equipment simulation tooling 1 is connected to a connector 2 arranged along the length direction of the equipment simulation tooling 1, and the bottom of the equipment simulation tooling 1 is provided with multiple connectors 2, such as two, three or more. The connector 2 at the bottom of the equipment simulation tooling 1 can be arranged along the length direction or the width direction, and the setting direction of each connector 2 can be completely consistent or partially consistent. Among them, the connector 2 is a flat steel, and a slide groove extending along the length of the flat steel itself is provided on the flat steel; the support 3 can be a shock absorber, or a model made according to the actual size of the shock absorber. The support 3 and the connector 2 are slidably plugged in through the slide groove. At least one support 3 is installed on each connector 2. The setting position of the support 3 is determined according to the actual situation. The operator can adjust the installation position of the support 3 by sliding the support 3.

[0035] S3. Position the equipment simulation tooling 1 on the base 10 located on the ground, and drill holes in the base 10 and the back support seat 20 on the bulkhead based on the bottom tooling and the back support tooling to fix the equipment simulation tooling 1.

[0036] In this embodiment, the center lines of the bottom and back of the equipment simulation tooling 1 are determined, and the equipment simulation tooling 1 is placed on the base 10 so that the center line of the bottom of the equipment simulation tooling 1 coincides with the center line of the base 10, and the center line of the back of the equipment simulation tooling 1 coincides with the center line of the back support seat 20. Specifically, since the equipment simulation tooling 1 is a rectangular frame, the center line of the bottom is the diagonal line of the bottom, the center line of the back is the diagonal line of the back, and the center line of the base 10 is the diagonal line of the base 10, and the center line of the back support seat 20 is the diagonal line of the back support seat 20, by aligning the diagonal line of the bottom with the diagonal line of the base 10, and the diagonal line of the back with the diagonal line of the back support seat 20, the installation position of the equipment simulation tooling 1 can be accurately located.

[0037] The support member 3 is provided with a through hole, and mounting holes are drilled on the base 10 and the back support seat 20 based on the through hole on each support member 3. After the mounting holes are drilled, the equipment simulation tooling 1 is fixed to the base 10 and the back support seat 20 with bolts. The mounting holes can be drilled with the support member 3 to ensure the accuracy of the mounting holes.

[0038] S4. Make a fixed wiring tool, install the fixed wiring tool on the equipment simulation tool 1, and cut the length of the cable connecting the electrical equipment based on the position of the fixed wiring tool.

[0039] The fixed wiring tooling includes a support plate 4 and a drawing 5. The support plate 4 is laid on the equipment simulation tooling 1, the equipment interface is printed on the drawing 5, and the drawing 5 is positioned on the support plate 4. The cable is cut based on the position of the equipment interface on the drawing 5.

[0040] Among them, the support plate 4 is composed of two layers of acrylic plates, and there is a sandwich between the two layers of acrylic plates for placing the drawing 5. Printing is performed on the drawing 5 according to the interface on the electrical equipment. Draw the center line on the drawing 5 and the acrylic plate respectively, insert the drawing 5 between the two layers of acrylic plates, and align and position it through the center line on the drawing 5 and the center line on the acrylic plate. The support plate 4 is fixed to the equipment simulation tooling 1, and the interface position printed on the drawing 5 corresponds to the interface position on the actual electrical equipment to ensure that the cable can be accurately cut. After the support plate 4 is fixed, the routing length of the cable to the interface on the drawing 5 is determined and the cable is cut. The cut cable is wired, and according to the interface information, such as the number of cable cores, cable model, and the corresponding aviation plug tail pin of each cable core, the corresponding aviation plug is selected to connect with the cable. In this embodiment, the support plate 4 plays the role of supporting the drawing 5, and the drawing 5 in the support plate 4 can be replaced. The interface patterns of various electrical equipment can be printed on the drawing 5. When the operator replaces the drawing 5, the purpose of routing for different interfaces can be achieved.

[0041] S5. Make a pipeline tool 6, install the pipeline tool 6 on the equipment simulation tool 1, and lay pipelines based on the pipeline tool 6.

[0042] A connecting hole 7 is opened on the pipeline fixture 6 based on the diameter of the pipeline, and the pipeline fixture 6 is installed on the equipment simulation fixture 1 based on the installation position size of the pipeline, so that the position of the connecting hole 7 corresponds to the installation position of the pipeline. After the installation of the pipeline fixture 6 is completed, the pipeline is installed and laid out in advance.

[0043] In this embodiment, the pipeline fixture 6 is a rectangular template, and a hole is opened on the pipeline fixture 6 based on the pipe diameter. It can be understood that the number of connection holes 7 is at least one. If there are multiple connection holes 7, the distance between two adjacent connection holes 7 is determined according to the actual setting position of the pipeline. The pipeline fixture 6 is positioned by the side of the pipeline fixture 6 to install the pipeline fixture 6 on the equipment simulation fixture 1, and the height and horizontal position of the connection hole 7 correspond to the height and horizontal position of the pipeline. After the pipeline template is installed, the pipeline of the electrical equipment can be installed and laid out in advance to improve work efficiency.

[0044] S6. Install the electrical equipment, lift the equipment simulation tooling 1 from the base 10, move the electrical equipment to the base 10 for positioning and installation, make the electrical equipment correspond to the mounting holes on the back support 20 and the base 10 and fasten them with bolts, then connect the cables to the corresponding interfaces on the electrical equipment, and connect the pre-laid pipelines to the electrical equipment.

[0045] The method of this embodiment pre-makes the equipment simulation tooling 1, fixed wiring tooling and management tooling in accordance with the original proportion to replace the actual equipment, pre-drills the installation holes on the base 10 and the back support seat 20, and simultaneously achieves the purpose of cutting cables and laying pipelines in advance. After removing the equipment simulation tooling 1 and placing the actual electrical equipment on the base 10, the electrical equipment at this time can be directly connected and fixed to the base 10 and the back support seat 20 by bolts, and the electrical equipment can be connected to the aviation plug and the pre-laid pipelines. This method changes the secondary installation into a single installation, improves the construction efficiency, reduces the workload of the construction personnel, and not only reduces the construction cost, but also effectively reduces the work intensity of the personnel on the slipway.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
