Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular, to an eccentric tray for facilitating the roller path transportation of ultra-wide sections. Background Art

[0002] In the actual use of shipbuilding in shipyards, due to its large transportation capacity, convenience and speed, roller path transportation has gradually become a new transportation mode that major shipyards compete to adopt.

[0003] However, in actual use, since the roller path is usually set beside buildings or immovable objects, once the transportation target exceeds the width of the roller path too much and the center of gravity exceeds the range of the roller path, the roller path cannot transport the target, otherwise it will cause the target to fall off the track, resulting in damage to the target or danger to the lives of the staff. Taking the construction of 23KTEU as an example, the widest part of the lashing bridge section reaches 11m, and the width of the roller path is generally about 3.5m, resulting in most roller paths being unable to transport this section, and other transportation methods need to be adopted, with low efficiency and high cost. Summary of the Invention

[0004] In view of the above-mentioned technical problem that the existing roller path cannot transport objects whose center of gravity exceeds the range of the roller path, an eccentric tray for facilitating the roller path transportation of ultra-wide sections is provided. The present invention mainly utilizes the setting of an eccentric tray on the roller path, and through the adjustment of the weight and center of gravity of the tray itself, the purpose of transporting ultra-wide parts by using the roller path can be achieved.

[0005] The technical means adopted by the present invention are as follows:

[0006] An eccentric tray for facilitating the roller path transportation of ultra-wide sections, the eccentric tray is arranged on the roller path, and a target object to be transported is arranged on the eccentric tray. The eccentric tray includes a connected tray center-of-gravity adjustment frame and a target-object center-of-gravity support frame. A center-of-gravity adjustment area is arranged inside the tray center-of-gravity adjustment frame, and a number of counterweights are arranged in the center-of-gravity adjustment area. The tray center-of-gravity adjustment frame includes a connected upper horizontal side, a lower horizontal side, a left vertical side, and a right vertical side. A first partition bar and a second partition bar are arranged inside the tray center-of-gravity adjustment frame from left to right. The first partition bar and the second partition bar divide the center-of-gravity adjustment area into three equal parts.

[0007] Further, a bottom sealing plate is arranged at the bottom of the tray center-of-gravity adjustment frame.

[0008] Further, the first partition bar, the upper horizontal side, the lower horizontal side, and the left vertical side form a first counterweight area, the upper horizontal side, the lower horizontal side, the first partition bar, and the second partition bar form a second counterweight area, and the second partition bar, the upper horizontal side, the lower horizontal side, and the right vertical side form a third counterweight area.

[0009] Further, the weight of the eccentric tray multiplied by the distance from the center of gravity of the tray to the support point is greater than twice the weight of the target transported object multiplied by the distance from the center of gravity of the target transported object to the support point.

[0010] Further, the lengths of the upper and lower horizontal edges are greater than or equal to the width of the roller path.

[0011] Further, the center-of-gravity support frame of the target object includes a plurality of support cross bars with one end connected to the right vertical edge, and a support vertical bar is connected to the other end of the support cross bars.

[0012] Further, the length of the support cross bar is greater than the center-of-gravity range of the target object.

[0013] Further, tray limit lines are provided on the ground on both sides of the eccentric tray.

[0014] Further, target-transported-object limit lines are provided on the ground on both sides of the target transported object.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] By providing the eccentric tray structure, the present invention enables the roller path to transport the target transported object even when the center of gravity exceeds the roller path.

[0017] The present invention discloses the relationship among the distance of the center of gravity of the tray, the weight of the tray, the distance of the center of gravity of the target transported object, and the weight of the target transported object. Through such a relationship setting, an over-wide target transported object can run smoothly on the roller path, and a safety factor of 2 is set to prevent the tray from tipping over due to jitter during transportation or offset of the loaded object.

[0018] By providing the vertical lines of the tray limit lines, the present invention assists in the assembly of the tray, enabling the tray to be assembled onto the roller path at the correct position and angle, and preventing the center of gravity from deviating from the predetermined position.

Detailed implementation mode

[0023] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0024] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and in no way restricts the present invention and its application or use. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] It should be noted that the terms used herein are only for describing the specific implementation modes and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations.

[0026] Unless otherwise specifically stated, the relative arrangements of the components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be clear that, for the convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but where appropriate, the said technologies, methods and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific values should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in the subsequent drawings.

[0027] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present invention: the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0028] For convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above-mentioned", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to cover different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0029] In addition, it should be noted that using words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without additional statement, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present invention.

[0030] Such as Figure 1 and Figure 2As shown in the figure, the present invention provides an eccentric tray for facilitating the transportation of ultra-wide segments on a roller path. The eccentric tray 1 is arranged on the roller path 2, and a target transported object 3 is arranged on the eccentric tray 1. The eccentric tray 1 includes a connected tray gravity adjustment frame and a target object gravity support frame. The bottom of the tray gravity adjustment frame is provided with a sealing bottom plate. Inside the tray gravity adjustment frame, there is a gravity adjustment area, and several counterweights 4 are arranged in the gravity adjustment area. The tray gravity adjustment frame includes a connected upper horizontal side 5, a lower horizontal side 6, a left vertical side 7, and a right vertical side 8. Inside the tray gravity adjustment frame, a first partition strip 9 and a second partition strip 10 are arranged from left to right. The first partition strip 9 and the second partition strip 10 divide the gravity adjustment area into three equal parts. The first partition strip 9, the upper horizontal side 5, the lower horizontal side 6, and the left vertical side 7 form a first counterweight area 11. The upper horizontal side 5, the lower horizontal side 6, the first partition strip 9, and the second partition strip 10 form a second counterweight area 12. The second partition strip 10, the upper horizontal side 5, the lower horizontal side 6, and the right vertical side 8 form a third counterweight area 13. When filling the counterweights 4 into the gravity adjustment area, first fill the first counterweight area 11. After the first counterweight area 11 is filled, fill the counterweights 4 into the second counterweight area 12. After the second counterweight area 12 is filled, fill the counterweights 4 into the third counterweight area 13. The lengths of the upper horizontal side 5 and the lower horizontal side 6 are greater than or equal to the width of the roller path 2. The target object gravity support frame includes several support cross bars 14 with one end connected to the right vertical side 8, and a support vertical bar 15 is connected to the other end of the support cross bars 14. The length of the support cross bars 14 is greater than the target object gravity range.

[0031] The center of gravity of the target transported object 3 exceeds the range of the roller path 2 but is within the range of the eccentric tray 1.

[0032] The weight of the eccentric tray 1 multiplied by the distance from the center of gravity of the eccentric tray 1 to the support point is greater than twice the weight of the target transported object 3 multiplied by the distance from the center of gravity of the target transported object 3 to the support point. By adjusting the position of the tray counterweights, the position of the tray center of gravity is adjusted to make T1L1 > 2*(T2*L2), where T1 is the weight of the eccentric tray, T2 is the weight of the target transported object, L1 is the distance from the center of gravity of the tray to the support point, and L2 is the distance from the center of gravity of the transported target object to the support point. A safety factor of 2 is taken to avoid the tilting of the tray caused by jitter or object placement deviation during transportation.

[0033] On the ground on both sides of the eccentric tray 1, there are tray limit lines. Figure 2 The position of the vertical line 16 of the tray limit line is shown in the figure. When the eccentric tray 1 is placed on the roller path 2, it is aligned to prevent misplacement. On the ground on both sides of the target transported object 3, there are target transported object limit lines. Figure 2 The position of the vertical line 17 of the target transported object limit line is shown in the figure to prevent the target object from being too wide and colliding with other machinery.

[0034] Use 400 I-beams to make the pallet gravity adjustment frame, and seal the bottom with steel plates to form open grids on the upper part; use 200 channel steels to make the gravity support area of the target object, which is as light as possible on the premise of ensuring strength.

[0035] The working state of the present invention is as follows: By calculation, obtain the weight of the eccentric pallet 1 and the position of the center of gravity of the eccentric pallet 1, and adjust the position of the center of gravity of the eccentric pallet 1 by adding counterweights 4 (the counterweights 4 can be made of scrap iron and other items, and the height should be lower than the upper surface of the pallet) in the preset grids to meet the conditions of the target transported object 3 (the weight and center of gravity of the target object can be obtained from the design drawings of the target object).

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
