Description

Technical Field

[0001] This invention relates to the field of marine parts processing technology, and in particular to a rapid fabrication device and method for marine template support. Background Technology

[0002] During shipbuilding, many pieces of equipment require electric power, which necessitates the laying of cables and wires to provide power. As electricity is the power source for shipboard equipment, cable and wire laying is a crucial and labor-intensive task. Shipboard cables and wires need to be laid over long distances; some ships, due to their large tonnage or numerous pieces of equipment, require thousands or even tens of thousands of kilometers of cable. Because of the long laying distances and complex routes, cable trays and supports are typically installed on the ship's hull structure for assistance. Cable trays are generally complex to manufacture and require specialized manufacturers, while cable supports are relatively simpler, usually made by bending templates according to the design department's layout dimensions. This results in a very large number of supports made from templates being used.

[0003] In addition, many pipelines on board, such as hydraulic pipelines and compressed air pipelines used for remote control and liquid level telemetry, are mainly made of copper and stainless steel. These pipelines generally have small diameters and are laid over long distances and areas, covering almost the entire ship. Pipe supports are required for the installation of these small-diameter copper and stainless steel pipes to facilitate installation and maintain an aesthetically pleasing appearance. Therefore, the installation of cables and wires and small-diameter pipelines on board requires a large number of template supports. These template supports are generally prefabricated according to the layout dimensions provided by the design department. However, due to various on-site factors such as welding deformation, complex channels, and inconvenient route layout, the form, size, and other specifications of the template supports need to be adjusted. However, after on-site measurement and layout, providing the templates to the manufacturer requires a significant amount of waiting time, resulting in production delays.

[0004] Chinese patent document publication number CN 222944239 U discloses a manual bending tool for flat iron, which uses a steel pipe to rotate in conjunction with a push rod to bend the flat iron. However, this structure is only suitable for products that require bending at large angles. The template strip needs to be bent at 90 degrees during processing, so it cannot meet the processing requirements of the template strip. Therefore, it is necessary to quickly manufacture and modify a large number of template strip supports on site to meet the needs of on-site laying. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies that cannot promptly process or modify template supports according to changes in construction location and structure at shipbuilding sites. This invention provides a rapid fabrication device and method for ship template supports, aiming to quickly process template supports that meet usage requirements based on on-site installation conditions.

[0006] This invention is achieved through the following technical solution: a rapid fabrication device for marine template strip supports, comprising a support plate set on the ground, an operating table set above the support plate, a fixing frame set on the upper part of the operating table, a bending device set on the upper part of the fixing frame, the bending device comprising a rotating shaft, a fastening block set on the side wall of the rotating shaft, a processing through groove for passing through the template strip body between the fastening block and the side wall of the rotating shaft, and a measuring device set on the side of the operating table.

[0007] Furthermore, a support channel steel is vertically provided on the upper surface of the support plate, and an opening slot is provided on the side of the fixing frame. The opening slot and the concave surface of the support channel steel are on the same vertical plane. The sum of the thicknesses of the operating table and the fixing frame is an integer multiple of 5 cm, and the front end faces of the operating table and the fixing frame are on the same vertical plane.

[0008] Furthermore, the upper surface of the fixing frame is provided with two support rods, the height of which is an integer multiple of 5cm. The two support rods are arranged opposite each other on both sides of the opening slot. Each support rod has a support tube at its top. The rotating shaft passes through the two support tubes laterally, and a hand crank is provided at one end of the rotating shaft.

[0009] Furthermore, multiple positioning holes are provided on the two side plates of the supporting channel steel, the positioning holes are equidistant from each other, and a positioning plate is movably installed in the positioning hole, the positioning plate being arranged parallel to the operating table.

[0010] Furthermore, the positioning hole has a rectangular cross-section, a connecting frame is provided on the side of the positioning plate, an opening is provided on the side of the connecting frame, and the connecting frame is connected to the positioning hole at the opening.

[0011] Furthermore, the positioning plate is located at the end away from the supporting channel steel, and the opening of the connecting frame is provided with a wedge-shaped head for easy insertion.

[0012] Furthermore, the upper surface of the connecting frame and the upper surface of the positioning plate are on the same horizontal plane.

[0013] A method for using a rapid fabrication device for marine template strip supports includes the following steps.

[0014] Step 1: Determine the length of the upper part of the first bend of the template strip and the length between the first bend and the second bend.

[0015] Based on the on-site laying conditions, calculate the length L1 of the template strip body when it is first bent. Use a tape measure or measuring tape to measure the diameter of the pipe or line to obtain the length L2 between the first bend and the second bend. Leave the remaining length on the template strip body behind the second bend.

[0016] Step 2, Install the positioning plate:

[0017] Based on the length L1 obtained in step one during the first bend, adjust the installation position of the mounting plate and insert the part with the larger cross-sectional area laterally into the positioning hole so that the distance between the upper surface of the mounting plate and the upper surface of the fixing frame is equal to L1.

[0018] Step 3: Determine the length of the upper part of the template strip during its first bend:

[0019] Select a template strip body of sufficient length, place one end of the template strip body vertically at the same height as the upper surface of the positioning plate, and let the side of the template strip body fit against the front face of the operating table and the fixing frame. At this time, the length of the template strip body body between the upper surface of the fixing frame and the positioning plate is L1.

[0020] Step four: Perform the first bend on the template strip body;

[0021] Pick up the template strip body along the upper surface of the fixing frame with one hand, and adjust the position of the hand crank handle with the other hand. Insert the end of the template strip body with the measured length L1 into the lower part of the machining slot, so that the head abuts against the lower surface of the fastening block. Then turn the hand crank handle to send the template strip body into the opening slot, so that pressure is generated between the hand crank handle and the template strip body. Continue to turn the hand crank handle and release the hand stabilizing the template strip body, and bend the upper part of the template strip body towards the opening slot side to complete the first bend.

[0022] Step 5: Perform a second bend on the template strip body:

[0023] Turn the hand crank handle to place the fastening block horizontally. Since the height of the support rod is known to be L3, calculate the positioning hole corresponding to the length L2 of the template strip body. At the corresponding position, use your hand to lift the template strip body upward so that your hand abuts against the bottom of the fastening block. Turn the hand crank handle to complete the second bending operation.

[0024] Step 6: Complete the on-site processing of the template strip body:

[0025] The tail of the template strip body after the second bend is pulled out from above the processing slot to complete the processing of the template strip body.

[0026] Furthermore, one end of the positioning plate protrudes from the front face of the operating table and the fixing frame, and in step three, the end of the template strip body abuts against the upper surface of the positioning plate.

[0027] Furthermore, a magnet is provided on the bottom surface of the opening groove, and the spacing between the positioning holes is 5cm.

[0028] The beneficial effects of this invention are as follows:

[0029] 1. By cooperating with the concave surface of the supporting channel steel and the opening slots on the operating table and the fixed frame, the template strip body is kept in a downward state during processing, which increases the stress area of ​​the template strip body during bending and improves the stability during processing.

[0030] 2. The bent part of the hand crank handle is on the same horizontal plane as the fastening block, which makes it easier to apply force with the hand when bending and reduces the difficulty of operation.

[0031] 3. The adjustable height positioning plate assists in measuring the bending length, which speeds up the dimensional measurement rate during bending and improves the processing speed.

[0032] 4. The length of the template strip can be directly located by hand, eliminating the need for positioning and scribing, thus improving positioning efficiency during processing.

[0033] 5. The positioning holes and connecting frame use a rectangular structure, which makes it easy for the positioning plate to remain horizontal and stable during connection, thus improving the accuracy of measurement. Attached Figure Description

[0041] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1

[0044] like Figure 1-6 As shown: This invention proposes a rapid fabrication device for marine template strip supports, mainly comprising a support plate 1 set on the ground, an operating platform 3 located above the support plate 1, a fixing frame 4 on the upper part of the operating platform 3, and a bending device on the upper part of the fixing frame 4. A support channel steel 2 is vertically installed on the upper surface of the support plate 1 to provide stable support for the device. The operating platform 3 and the fixing frame 4 are tightly connected, and the sum of their thicknesses is designed to be an integer multiple of 5cm. Furthermore, the front ends of the operating platform 3 and the fixing frame 4 are kept on the same vertical plane, facilitating subsequent positioning and measurement.

[0045] The upper surface of the mounting bracket 4 is provided with two opposing support rods 401, the height of which is also an integer multiple of 5cm. A support tube 402 is installed at the top. Figure 6 As shown, the rotating shaft 5 passes horizontally through two support tubes 402. One end of the rotating shaft 5 is equipped with a hand crank 501. The end of the hand crank 501 is knurled to facilitate manual control of the rotation of the rotating shaft 5 by the operator. A fastening block 6 is provided on the side wall of the rotating shaft 5. A processing through groove is formed between the fastening block 6 and the side wall of the rotating shaft 5 for passing through the template strip body for bending operations. The size of the processing through groove can accommodate the largest template strip body, which is convenient for rapid on-site processing.

[0046] Below the fastening block 6, the front end face of the operating table 3 and the fixing frame 4 is provided with a forward-opening slot. The opening slot and the concave surface of the supporting channel steel 2 are on the same vertical plane. The design of the opening slot and the supporting channel steel 2 increases the accommodation space of the template strip body, making it easier for the template strip body to be placed vertically when bending, increasing the contact area of ​​the template strip body, and thus improving the bending effect.

[0047] The two vertically positioned side plates of the supporting channel steel 2 are each equidistantly provided with multiple positioning holes 201. During use, the positioning holes 201 on both side plates, in conjunction with the positioning plate 7, allow for setting two different length positions, reducing the number of adjustments. The spacing between the positioning holes 201 is 5cm, facilitating the calculation of the template strip's length during bending. Figure 3 As shown, a positioning plate 7 is movably installed inside the positioning hole 201. The positioning plate 7 is parallel to the operating table 3 and is used to determine the bending position of the template strip body. A connecting frame 701 is provided on the side of the positioning plate 7. The cross-section of the positioning hole 201 and the connecting frame 701 is rectangular. When the connecting frame 701 is connected to the positioning hole 201, the connecting frame 701 can be horizontally locked inside the positioning hole 201 and remain stable. The side of the connecting frame 701 is provided with an opening. In use, it slides inward along the side of the support channel steel 2 through the opening. When it reaches the positioning hole 201, the connecting frame 701 is inserted into the positioning hole 201. The end of the connecting frame 701 is provided with a wedge-shaped head for easy insertion, which reduces the cross-sectional area of ​​the end and facilitates connection with the positioning hole 201. The upper surface of the connecting frame 701 and the upper surface of the positioning plate 7 are kept on the same horizontal plane to ensure the accuracy of the measurement. The mounting plate has connection holes, and positioning bolts can be screwed into the connection holes. When the positioning distance between the positioning plates 7 is too large, the positioning bolts are used to lift it up a certain distance, and the lower part of the template strip body abuts against the top of the positioning bolts, thereby determining a positioning distance with smaller error and improving the accuracy during bending.

[0048] In actual use, after determining the dimensions, the template strip body is inserted into the processing slot, and then the template strip body is placed vertically inside the opening slot. Magnets 403 are provided on the side of the opening slot to attract the template strip body. The hand crank 501 is turned counterclockwise, and the fastening block 6 presses the template strip body, bending the upper part of the template strip body forward to complete the bending operation. Because the fastening block 6 is tightly set with the processing slot, the template strip body can be bent to 90 degrees quickly during bending. Since the thickness of the template strip body is generally 3-5mm, it can be completed quickly using the hand crank 501. Furthermore, inside the processing slot, the side near the rotating shaft 5 is an arc-shaped surface, which reduces resistance and improves the bending effect during the bending process.

[0049] The specific operating method is as follows:

[0050] Step 1: First, based on the on-site laying conditions, calculate the length L1 from the top of the template strip to the bend point during the first bend. Then, use a measuring device to measure the diameter of the pipe or line to obtain the length L2 between the first bend point and the second bend point. Furthermore, the template strip needs to reserve an additional length behind the second bend point to facilitate better operation during subsequent use.

[0051] Step two: Based on the calculated length L1, adjust the installation position of the positioning plate 7. Insert the connecting frame 701 on the positioning plate 7 horizontally into the corresponding positioning hole 201, ensuring that the distance between the upper surface of the positioning plate 7 and the upper surface of the fixing frame 4 is equal to or close to L1 (an error of about 3cm is allowed during the bending process of the template strip). The equidistant setting between the positioning holes 201 (such as a 5cm spacing) and the wedge head design on the positioning plate 7 greatly improve the accuracy and convenience of positioning. Furthermore, the positioning plate 7 uses the connecting frame 701 to connect with the positioning hole 201, which facilitates timely adjustment of the positioning length according to the on-site processing conditions. Within the allowable error range, this improves the accuracy of measuring the template strip body, enhances the dimensional accuracy during bending, and ensures the effectiveness of use.

[0052] Step 3: Select a template strip with the required overall length, place one end vertically at the same height as the upper surface of the positioning plate 7, and align the side with the front face of the operating table 3 and the fixing frame 4. At this point, the length of the template strip between the upper surface of the fixing frame 4 and the positioning plate 7 is L1, achieving precise positioning of the first bending length.

[0053] Step four: Next, perform the first bending operation. Use your hand to pick up the template strip body along the upper surface of the fixing frame 4. Use your other hand to adjust the position of the hand crank handle 501. Insert the end of the template strip body with the measured length L1 into the lower part of the processing slot, so that your hand abuts against the lower surface of the fastening block 6. Turn the hand crank handle 501 counterclockwise to send the template strip body into the opening slot. Pressure is generated between the hand crank handle 501 and the template strip body. Continue to turn the hand crank handle 501 and release your hand on the template strip body to bend the upper part of the template strip body towards the opening slot side to complete the first bending.

[0054] Step 5: After the first bend is completed, perform the second bend. Turn the hand crank 501 back, place the fastening block 6 horizontally, and adjust the position of the template strip body so that the lower part of the template strip body remains vertical. Figure 4As shown, since the height of the support rod 401 is known to be L3, the position of the corresponding positioning hole 201 can be calculated based on the length L2 (L2 = L3 + thickness of the fixing frame 4 + thickness of the operating table 3 + N * 5CM, where N is the calculated number of downward positioning holes 201). At the corresponding positioning hole 201 position, use your hand to lift the template strip body upwards. At this point, the distance from your hand to the fastening block 6 is the distance between the first and second bends. Use your other hand to assist in cranking the handle 501 to facilitate lifting the template strip body upwards. Once your hand abuts against the bottom of the fastening block 6, rotate the handle 501 to complete the second bend. The magnet 403 on the bottom surface of the opening groove helps to fix the position of the template strip body, assists in positioning the template strip body, reduces its displacement during bending, and improves the bending effect.

[0055] Step six: Pull the tail of the template strip body after the second bend from the top of the processing slot to complete the processing of the template strip body. The processed template strip bracket can be directly used for on-site laying, and the bending size of the template strip body can be adjusted in a timely manner according to the on-site construction conditions, which greatly improves work efficiency and laying quality.

[0056] In practical applications at shipbuilding sites, this device not only solves the problem of production delays inherent in traditional methods but also meets complex and varied laying requirements by rapidly fabricating and modifying template supports on-site. Furthermore, its ease of operation and accurate positioning significantly improve the fabrication precision and consistency of template supports, providing strong support for the stable operation of ship electrical systems and the reliable installation of small-diameter pipelines. In addition, the device boasts advantages such as compact structure and small footprint, allowing a single person to quickly fabricate cable and wire template supports and small-diameter pipe supports on-site based on design specifications or on-site layout dimensions, making it ideal for use in space-constrained environments such as shipbuilding sites.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
