Description

Technical Field

[0001] The invention belongs to the technical field of ships, and in particular relates to a symmetrical sizing and marking tool for a PCTC lashing bowl. Background Art

[0002] PCTC, which means Pure Car and Truck Carrier in Chinese, is a type of RoRo ship. This type of ship is specially used to carry cargo vehicles. It is a special ship that uses cargo vehicles to carry cargo. A tractor can tow a semi-trailer or wheeled pallet carrying box cargo or other piece cargo directly in and out of the cargo hold for loading and unloading.

[0003] Ship block construction is a complex and delicate process, and the first step is the cutting of steel plates. Before cutting the steel plates, it is crucial to accurately mark the necessary information such as the assembly line on the steel plates. This step is an indispensable prerequisite for the cutting process. Since the amount of information required to be marked on the steel plates is quite large, including but not limited to assembly lines, cutting lines, positioning marks, etc., the marking work takes about 1.5 hours. This long preparation time directly leads to a significant increase in the operating time of the cutting station when processing a single steel plate, far exceeding other production links such as the paneling station and the longitudinal bone station. This time difference and imbalance eventually caused the blockage of the entire assembly line, affecting production efficiency and progress. Therefore, optimizing the marking process and shortening the marking time are of great significance to improving the overall efficiency of ship block construction.

[0004] The large number of lashing bowls on the fixed deck / movable deck of PCTC does bring a heavy load to the cutting station during the ship block construction process. The marking work of the lashing bowls, especially when using mechanized or automated methods, often takes a long time due to the need for high precision and a large number of hole processing. For example, it takes one and a half hours for every 600 holes, which undoubtedly increases the pressure on the cutting station and limits the production capacity of the assembly line.

[0005] In order to ease this pressure, the method of marking the lashing holes is considered to be adjusted to manual marking. Although this method can reduce the dependence on specific equipment to a certain extent, it also brings new problems. Manual marking not only takes a lot of time, but also the accuracy of marking is difficult to guarantee compared with mechanized or automated methods, which may affect the subsequent assembly and fixing work, and even pose a potential threat to the structural safety and stability of the entire ship.

[0026] like Figure 1 As shown, Figure 1 A PCTC binding bowl symmetrical sizing and marking tool provided in the embodiment of the present application includes a concentric fixing device 100, the concentric fixing device 100 includes a base 110 arranged at the bottom, a cover plate 120 arranged at the upper end of the base 100, and an axial column 130 perpendicular to the cover plate 120 and extending outward along the cover plate; a connecting device 200, the connecting device 200 includes a concentric circular tube 210, a base 220 radially arranged outward along the concentric circular tube, the concentric circular tube 210 is sleeved on the outside of the axial column 130, and the connecting device is rotatably connected to the concentric fixing device. A pen holder device 300, the pen holder device 300 includes a fixing portion 310 and a supporting portion 320, the fixing portion 310 is connected to the base 220, and the supporting portion 320 is used to support a marking tool, such as a marker pen.

[0027] By setting up the sizing and marking tool, the size design of the base is matched with the binding hole of the binding bowl, the base is placed in the binding hole, and the cover plate is fitted to the bottom plate outside the binding hole to keep the base stable. The connection position of the marking device and the connecting device is adjusted according to requirements, and the distance from the pen holder device to the axis column can be adjusted. After the distance is fixed, the connecting device and the pen holder device rotate around the axis column to complete the marking work.

[0028] Specifically, refer to Figure 2 , Figure 2 The concentric fixture 100 comprises a base 110 disposed at the bottom, a cover plate 120 disposed at the top of the base 100 and an axial column 130 perpendicular to the cover plate 120 and extending outwardly along the cover plate.

[0029] In a specific embodiment, the base 110 is made of 5 mm thick steel, the cover plate 120 is made of 2.5 mm thick steel plate, and the cover plate has a diameter of 60 mm. The shaft column 130 is made of a 10 mm×105 mm cylindrical pin, and the lower end is fixed to the cover plate 120 .

[0030] The center of the base 110 and the cover plate 120 is positioned by a lathe and a 8 mm thread hole is opened, and a thread with a diameter of 8 mm and a length of 8 mm is tapped at the lower end of the shaft column 130. The shaft column 130 is connected to the base 110 and the cover plate 120 by threads.

[0031] The base is used to be placed in the lashing hole corresponding to the lashing bowl. The steel of corresponding thickness can be selected according to the thickness of the lashing hole to play a positioning role. The diameter of the cover plate is larger than the diameter of the base, and it is clipped to the outer ring of the lashing hole. It mainly plays the role of keeping the concentric fixture horizontal and stable, making the center of gravity of the tooling vertical, and avoiding accuracy deviation caused by different angles.

[0032] In another embodiment, the concentric fixing device further includes a spring 140. The spring 140 is sleeved outside the shaft column 130. Specifically, the spring uses a cylindrical spring with a steel wire diameter of 0.8 mm, a spring diameter of 10 mm, and a height of 30 mm. The main function is to allow the marking device to move up and down along the shaft column. When in use, the spring is pressed down to make the marking clear. When not in use, the spring is relaxed, and the marking device is retracted to avoid wear of the pen tip.

[0033] Specifically, the springs are sequentially sleeved on the axial column, and are sequentially connected with the cover plate and the base to complete the assembly of the concentric fixing device.

[0034] like Figure 3 As shown, Figure 3 A schematic diagram of the structure of a connecting device of a symmetrical sizing and marking tool is shown. The connecting device 200 includes a concentric circular tube 210 and a base 220. Specifically, the concentric circular tube 210 is a stainless steel tube with a diameter of 10 mm, a length of 50 mm, and a wall thickness of 1 mm. The base 220 is two stainless steel sheets with a length of 60 mm, a width of 33 mm, and a thickness of 3 mm. The concentric circular tube 210 is connected to the axis column, and the two play the role of axial rotation, and in order to ensure that the precision is reliable and there is no shaking during marking, the radius tolerance of the two components shall not exceed 50 microns. The base 220 is horizontally distributed around the concentric circular tube 210 at an interval of 180°. The concentric circular tube 210 is fixedly connected to the base 220, for example, it can be connected by welding.

[0035] In another embodiment, if Figure 4 As shown, Figure 4 The schematic diagram of the structure of another symmetrical sizing and marking tool connection device is shown. The base 220 can be three stainless steel sheets, which are horizontally distributed around the concentric tube 210 at intervals of 120 degrees. Furthermore, the base 220 can be four or five or more stainless steel sheets, which are evenly distributed around the concentric tube 210.

[0036] Furthermore, the base 220 includes a through slot 221, which can be opened at the center of the steel sheet of the base 220, and is used for connecting with the pen holder device, and the base is slidably connected with the pen holder device through the through slot. Specifically, an 8mm wide through slot is milled in the center along the width extension direction of the steel sheet.

[0037] like Figure 5 As shown, Figure 5 The figure is a schematic diagram of the structure of a pen holder device of a symmetrical sizing and marking tool. The pen holder device 300 includes a fixing portion 310 and a supporting portion 320. Specifically, the fixing portion 310 is a steel sheet, 70 mm long and 33 mm wide, and two 6 mm screw holes are opened on the width center line of the fixing portion 310, wherein one hole is used for sliding positioning and the other hole is used to lock the sliding distance. The fixing portion 310 and the base 220 on the connecting device are fixed in cooperation. Specifically, by passing the screw through the screw hole on the fixing portion 310 and the through slot on the base 220, the sliding of the screw in the through slot can drive the pen holder device to slide along the through slot, thereby making the pen holder device 300 away from the axis column 130 or close to the axis column 130, so as to achieve smooth sliding and achieve the purpose of changing the marking diameter.

[0038] The support part 320 is designed as an open circular tube, wherein the circular tube is a stainless steel tube with a diameter of 10 mm, a height of 28 mm, and a wall thickness of 1 mm, and is cut through along the length direction of the cylinder to form a C-shaped column.

After the concentric fixing device is connected to the connecting device, the upper end of the connecting device is locked using the first locking device. Specifically, the concentric circular tube of the connecting device is sleeved on the outside of the shaft column, and after pressing down the spring sleeved on the shaft column, the nut is tightened on the thread at the upper end of the shaft column, which plays the role of locking the connecting device. Among them, the first locking device can be a nut that matches the thread at the upper end of the shaft column.

[0040] In another embodiment, a second locking device 500 is provided at the lower end of the shaft column 130. The second locking device 500 can move along the axial direction of the shaft column. Specifically, the shaft column 130 adopts a 10mm×105mm cylindrical pin, the tapping diameter of the lower end is 8mm and the thread length is 8mm, the tapping diameter of the upper end is 10mm and the thread length is 15mm, and the tolerance of the middle part is negative 50 microns. The shaft column is connected to the base, the cover plate, the second locking device, the spring, the concentric tube of the connecting device, and the first locking device in sequence. Among them, the spring is pressed against the second locking device, and the compression degree of the spring can be adjusted by adjusting the position of the second locking device on the shaft column. Among them, the second locking device can be a nut that matches the thread at the lower end of the shaft column.
