Description

Technical Field

[0001] This invention relates to the field of container ship construction technology, and in particular to a conical seat positioning auxiliary device. Background Technology

[0002] Container ships are primarily used for transporting containers. To ensure the stability of containers during transport, container ships are equipped with conical decks, also known as stacking cones. Common conical deck structures include... Figure 1 , Figure 2 As shown, each container has a positioning groove at its bottom corner that matches a conical seat. When placing the container, it is hoisted into the corresponding positioning groove and aligned vertically with the conical seat. Then, the container is lowered, allowing each conical seat to insert into its corresponding positioning groove. This achieves horizontal positioning of the container. The conical seats also exert horizontal constraints on the container, preventing it from moving horizontally along the deck. The conical seats and container guide rails together constrain the container, thus preventing slippage. Therefore, the position and dimensions of each conical seat on the deck must be precise to ensure the container can be smoothly lowered into the conical seat.

[0003] With the development of digital technology, 3D scanning simulation test chamber technology has become increasingly mature. It utilizes 3D scanning technology to scan and analyze the overall state of the cargo hold guide rails, obtaining information such as the longitudinal and lateral spacing of the guide rail frames within the cargo hold. Current simulation test chamber software, ECO-PASS, can automatically calculate the center of the conical seat by scanning its projection in a top-down direction, thereby quickly determining the lateral and longitudinal positions of the conical seat on the deck, and thus determining whether the installation dimensions of the conical seat on the deck meet the design requirements. However, as... Figure 1 As shown, the top view of the conical seat is an I-shaped structure. The web of the I-shaped structure is arranged laterally and has a large arc transition between it and the two flanges located at both ends of the I-shape. The outer sides of the two flanges are also arc-shaped. Because the conical seat has many arc surfaces and tapers in the vertical direction, there is a large sampling error when scanning the shape of the conical seat. This will cause a large difference between the conical seat contour created by the scanning data and the actual contour. The center of the conical seat determined by the scanning contour deviates greatly from the actual center, resulting in insufficient positioning of the conical seat. Summary of the Invention

[0004] The technical problem to be solved by the present invention is as follows: In order to solve the above-mentioned technical problem, the purpose of the present invention is to provide a conical seat positioning auxiliary device, including a transverse positioning member arranged in the transverse direction along the conical seat and a longitudinal positioning member arranged in the longitudinal direction along the conical seat. The bottom of the transverse positioning member is provided with a first limiting groove with the opening facing downward. The groove width of the first limiting groove gradually increases from top to bottom, and the two side groove walls of the first limiting groove are symmetrically arranged about the transverse center plane of the first limiting groove, so that when the transverse positioning member is placed on the conical seat, the transverse center plane of the first limiting groove coincides with the transverse center plane of the conical seat.

[0005] The longitudinal positioning member is slidably arranged in the middle of the transverse positioning member. The bottom of the longitudinal positioning member is provided with a second limiting groove with the opening facing downward. The transverse center plane of the second limiting groove coincides with the transverse center plane of the first limiting groove. The groove width of the second limiting groove gradually increases from top to bottom, and the two side walls of the second limiting groove are symmetrically arranged about the longitudinal center plane of the second limiting groove, so that when the longitudinal positioning member is placed on the web of the conical seat, the longitudinal center plane of the second limiting groove coincides with the longitudinal center plane of the conical seat.

[0006] The upper end of the longitudinal positioning member is provided with a marking point, and the projection of the center of the marking point on the horizontal plane coincides with the center line of the second limiting groove.

[0007] As a preferred embodiment, a reflective sheet is attached to the top of the longitudinal positioning member, and the marking point is set on the reflective sheet.

[0008] As a preferred embodiment, the top of the longitudinal positioning member is fixed with a horizontally arranged guide plate, the top of the transverse positioning member is provided with a guide groove that matches the guide plate, and the marking point is set on the top of the guide plate.

[0009] As a preferred embodiment, the top of the longitudinal positioning component is equipped with a level.

[0010] As a preferred embodiment, both the first limiting groove and the second limiting groove are in the shape of an isosceles trapezoid or an inverted V.

[0011] As a preferred embodiment, both ends of the lateral positioning member are provided with first bolts passing through them, and the lower end of each first bolt abuts against the deck.

[0012] As a preferred embodiment, the longitudinal positioning member has a second bolt inserted at both ends, and the lower end of each second bolt abuts against the deck.

[0013] A method for measuring the installation position of a conical seat includes the following steps:

[0014] Place the aforementioned conical seat positioning auxiliary device on the conical seat, and press down on the transverse positioning member so that the two side walls of the first limiting groove abut against the outer sides of the two side wing plates of the conical seat respectively.

[0015] Press down on the longitudinal positioning member so that the two side walls of the second limiting groove abut against the two sides of the web of the conical seat;

[0016] Measure the distance between the marked point on the longitudinal positioning element and the reference object.

[0017] As a preferred embodiment, after pressing down on the lateral positioning member, adjust each of the first bolts until the lower end of each of the first bolts abuts against the deck, so that the lateral positioning member remains stable.

[0018] After pressing down on the longitudinal positioning member, adjust each of the second bolts until the lower end of each of the second bolts abuts against the deck, so that the longitudinal positioning member remains stable.

[0019] As a preferred embodiment, while keeping the two side walls of the first limiting groove abutting against the outer sides of the two side wings of the conical seat, and the two side walls of the second limiting groove abutting against the two sides of the web of the conical seat, the transverse positioning member and the longitudinal positioning member are adjusted so that the bubble of the level is located at the center of the bubble meter.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] The conical seat positioning auxiliary device of the present invention includes a transverse positioning member arranged transversely along the conical seat and a longitudinal positioning member arranged longitudinally along the conical seat. The bottom of the transverse positioning member has a first limiting groove with its opening facing downwards. The width of the first limiting groove gradually increases from top to bottom, and the two side walls of the first limiting groove are symmetrically arranged about the transverse center plane of the first limiting groove. When the transverse positioning member is placed on the conical seat, the first limiting groove can center and coincide with the transverse center plane of the conical seat. The longitudinal positioning member is slidably guided vertically in the middle of the transverse positioning member. The bottom of the longitudinal positioning member has a second limiting groove with its opening facing downwards. The width of the second limiting groove gradually increases from top to bottom, and the two side walls of the second limiting groove are symmetrically arranged about the longitudinal center plane of the second limiting groove. When the transverse positioning member is placed on the web of the conical seat, sliding the second limiting groove downwards can center the longitudinal center plane of the second limiting groove to coincide with the conical seat. The longitudinal center planes of the seat coincide, and a marker point is provided at the upper end of the longitudinal positioning component. The projection of the center of the marker point onto the horizontal plane coincides with the center line of the second limiting groove. Since the transverse center plane of the second limiting groove coincides with the transverse center plane of the first limiting groove, the transverse center plane of the first limiting groove coincides with the transverse center plane of the conical seat, and the longitudinal center plane of the second limiting groove coincides with the longitudinal center plane of the conical seat, the intersection line of the transverse center plane and the longitudinal center plane of the conical seat is coaxial with the center line of the second limiting groove. Therefore, the coordinates of the marker point on the horizontal plane are the same as the coordinates of the center line of the conical seat on the horizontal plane. Thus, when using the conical seat positioning auxiliary device of the present invention to measure the horizontal coordinates of the conical seat, only the coordinates of the marker point on the horizontal plane need to be measured. It is not necessary to scan and model the outer contour of the conical seat, thus avoiding the error caused by the deviation of the scanned conical seat contour from the actual conical seat contour and improving the positioning accuracy of the conical seat.

Detailed Implementation

[0031] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0032] In the description of this invention, it should be understood that the terms "upper," "lower," "left," "right," "top," "bottom," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be understood that the terms "first," "second," etc., are used in this invention to describe various information, but this information should not be limited to these terms; these terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this invention, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0033] like Figures 3 to 8 As shown, the present invention provides a conical seat positioning auxiliary device, including a transverse positioning member 1 arranged transversely along the conical seat 100 and a longitudinal positioning member 2 arranged longitudinally along the conical seat 100. The bottom of the transverse positioning member 1 is provided with a first limiting groove 11 with the opening facing downward. The groove width of the first limiting groove 11 gradually increases from top to bottom, and the two side groove walls of the first limiting groove 11 are symmetrically arranged about the transverse center plane O-Y2 of the first limiting groove 11, so that when the transverse positioning member 1 is placed on the conical seat 100, the transverse center plane O-Y2 of the first limiting groove 11 coincides with the transverse center plane O-Y1 of the conical seat 100.

[0034] The longitudinal positioning member 2 is arranged in the middle of the transverse positioning member 1, and the bottom of the longitudinal positioning member 2 is provided with a second limiting groove 21 with the opening facing downward. The transverse center plane O-Y3 of the second limiting groove 21 coincides with the transverse center plane O-Y2 of the first limiting groove 11. The groove width of the second limiting groove 21 gradually increases from top to bottom, and the two side groove walls of the second limiting groove 21 are symmetrically arranged about the longitudinal center plane O-X3 of the second limiting groove 21, so that when the longitudinal positioning member 2 is covered on the web of the tapered seat 100, the longitudinal center plane O-X3 of the second limiting groove 21 coincides with the longitudinal center plane O-X1 of the tapered seat 100.

[0035] The upper end of the longitudinal positioning member 2 is provided with a marker point 3, and the projection of the center of the marker point 3 on the horizontal plane coincides with the center line of the second limiting groove 21.

[0036] Specifically, since the transverse center plane O-Y3 of the second limiting groove 21 coincides with the transverse center plane O-Y2 of the first limiting groove 11, the transverse center plane O-Y2 of the first limiting groove 11 coincides with the transverse center plane O-Y1 of the conical seat 100, and the longitudinal center plane O-X3 of the second limiting groove 21 coincides with the longitudinal center plane O-X1 of the conical seat 100; therefore, the intersection line of the transverse center plane O-Y1 and the longitudinal center plane O-X1 of the conical seat 100 coincides with the second limiting groove 21. Since the center line of the limiting groove 21 is coaxial, the coordinates of the mark point 3 on the horizontal plane are the same as the coordinates of the center line of the conical seat 100 on the horizontal plane. Therefore, when using the conical seat positioning auxiliary device of the present invention to measure the horizontal coordinates of the conical seat 100, it is only necessary to measure the coordinates of the mark point 2 on the horizontal plane. It is not necessary to scan and model the outer contour of the conical seat 100, thus avoiding the error caused by the scanning of the conical seat contour deviating from the actual conical seat contour and improving the positioning accuracy of the conical seat 100.

[0037] To facilitate scanning of the marker point 3, in this embodiment, a reflective sheet 8 is attached to the top of the longitudinal positioning member 2, and the marker point 3 is set on the reflective sheet 8.

[0038] There are several ways to slide the longitudinal positioning member 2 onto the transverse positioning member 1. For example, an upwardly extending guide post can be provided at the upper middle of the transverse positioning member 1, and a guide hole can be provided on the longitudinal positioning member 2. In this embodiment, a horizontally arranged guide plate 7 is fixed to the top of the longitudinal positioning member 2, and a guide groove 12 matching the guide plate 7 is provided on the top of the transverse positioning member 1. A marking point 3 is provided on the top of the guide plate 7. Specifically, both the longitudinal positioning member 1 and the transverse positioning member 2 are gantry-type, and their middle parts are arranged perpendicularly. The edge of the guide plate 7 is elliptical, allowing the guide plate 7 to slide up and down in the guide groove 12 without rotating within it. In other embodiments of the present invention, the guide plate 7 can be square or arc-shaped. It is only necessary to provide anti-rotation protrusions on the edge of the guide plate and anti-rotation grooves matching the anti-rotation protrusions in the guide groove 12.

[0039] Furthermore, to ensure the placement accuracy of the lateral positioning component 1 and the longitudinal positioning component 2, in this embodiment, a level 4 is provided on the top of the longitudinal positioning component 2. Specifically, the level 4 can be a disc-shaped bubble level, a T-shaped bubble level, or two vertically arranged tubular levels. The level 4 avoids the influence of the tilt of the lateral positioning component 1 and the longitudinal positioning component 2 on the positioning accuracy.

[0040] In this embodiment, both the first limiting groove 11 and the second limiting groove 21 are isosceles trapezoids or inverted V-shaped. The inverted V-shaped groove and the isosceles trapezoidal groove enable the transverse positioning member 1 and the longitudinal positioning member 2 to be automatically aligned.

[0041] In this embodiment, both ends of the transverse positioning member 1 are provided with first bolts 5 passing through them, and the lower end of each first bolt 5 abuts against the deck. The setting of the first bolts 5 not only facilitates the stability of the transverse positioning member 1 after positioning is completed, but also increases the size of the conical seat that the transverse positioning member 1 can be used for. Specifically, when the conical seat is large, the height and width of the conical seat are both high. By adjusting the height of the lower end of the first bolt 5 protruding from the transverse positioning member 1, the applicability range of the transverse positioning member 1 can be made wider.

[0042] In this embodiment, the longitudinal positioning member 2 has two second bolts 6 inserted at both ends, and the lower end of each second bolt 6 abuts against the deck.

[0043] An embodiment of a method for measuring the mounting position of a conical seat includes the following steps:

[0044] Place the aforementioned conical seat positioning auxiliary device on the conical seat 100 and press down on the transverse positioning member 1 so that the two side walls of the first limiting groove 11 abut against the outer sides of the two side wing plates of the conical seat 100 respectively.

[0045] Pressing down on the longitudinal positioning member 2 causes the two side walls of the second limiting groove 21 to abut against the two sides of the web of the conical seat 100. Specifically, when pressing down on the longitudinal positioning member 2, the transverse positioning member 1 can move longitudinally but cannot move laterally. After the longitudinal positioning member 2 and the transverse positioning member 1 are aligned, the longitudinal center plane O-X2 of the transverse positioning member can be spaced apart from the longitudinal center plane O-X1 of the conical seat 100.

[0046] Measure the distance between the mark point 3 on the longitudinal positioning component 2 and the reference object. Specifically, a total station or scanner can be used to measure the distance between the mark point 3 on the longitudinal positioning component 2 and the reference object, which is the guide rail inside the cargo hold.

[0047] Among them, after pressing down the transverse positioning component 1, adjust each first bolt 5 until the lower end of each first bolt 5 abuts against the deck so that the transverse positioning component 1 remains stable.

[0048] After pressing down on the longitudinal positioning member 2, adjust each of the second bolts 6 until the lower end of each of the second bolts 6 abuts against the deck, so that the longitudinal positioning member 2 remains stable.

[0049] While keeping the two side walls of the first limiting groove 11 abutting against the outer sides of the two side wings of the conical seat 100, and the two side walls of the second limiting groove 21 abutting against the two sides of the web of the conical seat 100, adjust the transverse positioning member 1 and the longitudinal positioning member 2 so that the bubble of the level 4 is located at the center of the bubble meter.

[0050] In summary, the conical seat positioning auxiliary device of the present invention includes a transverse positioning member 1 arranged transversely along the conical seat 100 and a longitudinal positioning member 2 arranged longitudinally along the conical seat 100. The bottom of the transverse positioning member 1 is provided with a first limiting groove 11 with its opening facing downward. The groove width of the first limiting groove 11 gradually increases from top to bottom, and the two side walls of the first limiting groove 11 are symmetrically arranged about the transverse center plane O-Y2 of the first limiting groove 11, so that when the transverse positioning member 1 is placed on the conical seat 100, the transverse center plane O-Y2 of the first limiting groove 11 coincides with the transverse center plane O-Y1 of the conical seat 100. The longitudinal positioning member 2 is arranged vertically and horizontally in the middle of the transverse positioning member 1. A second limiting groove 21 with its opening facing downward is provided at the bottom of the positioning member 2. The transverse center plane O-Y3 of the second limiting groove 21 coincides with the transverse center plane O-Y2 of the first limiting groove 11. The groove width of the second limiting groove 21 gradually increases from top to bottom, and the two side walls of the second limiting groove 21 are symmetrically arranged about the longitudinal center plane O-X3 of the second limiting groove 21, so that when the longitudinal positioning member 2 is placed on the web of the tapered seat 100, the longitudinal center plane O-X3 of the second limiting groove 21 coincides with the longitudinal center plane O-X1 of the tapered seat 100. A marking point 3 is provided at the upper end of the longitudinal positioning member 2, and the projection of the center of the marking point 3 on the horizontal plane coincides with the center line of the second limiting groove 21. Since the transverse center plane O-Y3 of the second limiting groove 21 coincides with the transverse center plane O-Y2 of the first limiting groove 11, the transverse center plane O-Y2 of the first limiting groove 11 coincides with the transverse center plane O-Y1 of the conical seat 100, and the longitudinal center plane O-X3 of the second limiting groove 21 coincides with the longitudinal center plane O-X1 of the conical seat 100; therefore, the intersection line of the transverse center plane O-Y1 and the longitudinal center plane O-X1 of the conical seat 100 is perpendicular to the second limiting groove 21. Since the centerline of groove 21 is coaxial, the coordinates of marker point 3 on the horizontal plane are the same as the coordinates of the centerline of conical seat 100 on the horizontal plane. Therefore, when using the conical seat positioning auxiliary device of the present invention to measure the horizontal coordinates of conical seat 100, only the coordinates of marker point 2 on the horizontal plane need to be measured. It is not necessary to scan and model the outer contour of conical seat 100, thus avoiding errors caused by the scanning of the conical seat contour deviating from the actual conical seat contour and improving the positioning accuracy of conical seat 100. Moreover, by setting the reflector 8, it is convenient for the total station or scanner to identify marker point 3, solving the problem that the scanner or total station cannot fully scan the conical seat due to the obstruction of the bulkhead. This improves the accuracy and consistency of the total station and scanner when measuring conical seats. It has been verified that the positioning data error of the conical seat measured by different operators using the conical seat positioning auxiliary device of the present invention does not exceed 1mm.

[0051] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
