Description

Technical Field

[0001] This invention belongs to the field of shipbuilding technology, specifically relating to a connection tooling for assembled railcars and its rapid deployment method. Background Technology

[0002] Ship loading and unloading is a critical process in shipbuilding, encompassing the transfer of completed ships to floating docks or the water surface, and the relocation of ships requiring maintenance or repair to land-based slipways. For floating dock-type ship loading and unloading, after the rails on the floating dock floor and the land slipway are aligned, the railcar trolleys must be precisely positioned before the ship is safely and smoothly transferred, and finally, the railcar trolleys are disassembled. However, existing technologies require multiple repositioning of the railcars based on the ship's transfer location, necessitating repeated positioning operations. This is labor-intensive, cumbersome, and inefficient. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a method for connecting and quickly arranging assembled shipboard upper and lower track railcars, which can effectively solve the problems of cumbersome operation, high labor intensity and low construction efficiency in the existing technology.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A connecting fixture for an assembled railcar assembly is provided. The connecting fixture is used to connect two adjacent railcars. It includes a channel steel, a first connecting panel, a second connecting panel, a first connecting lug, and a second connecting lug. The first connecting panel and the second connecting panel are respectively disposed at the left and right ends of the channel steel and are fixedly connected to the channel steel. The first connecting lug is connected to the first connecting panel by a first bolt and nut pair, and the second connecting lug is connected to the second connecting panel by a second bolt and nut pair. The ends of the first connecting lug and the second connecting lug are provided with downward protruding welding parts for welding to the railcars.

[0006] As a preferred embodiment of the present invention, the rail trolley is provided with a groove into which the welding part can be inserted.

[0007] As a preferred embodiment of the present invention, a first reinforcing ear plate is provided on the side of the first connecting ear plate away from the channel steel, and a second reinforcing ear plate is provided on the side of the second connecting ear plate away from the channel steel. The shapes of the first reinforcing ear plate and the second reinforcing ear plate are the same as the shapes of the first connecting ear plate and the second connecting ear plate. The forward projected area of ​​the first reinforcing ear plate and the forward projected area of ​​the second reinforcing ear plate are both smaller than the forward projected area of ​​the first connecting ear plate and the forward projected area of ​​the second connecting ear plate.

[0008] As a preferred embodiment of the present invention, anti-loosening washers are provided between the nut of the first bolt and nut pair and the first reinforcing lug, and between the nut of the second bolt and nut pair and the second reinforcing lug.

[0009] As a preferred embodiment of the present invention, the channel steel is provided with a plurality of lifting lugs, which are arranged at uniform intervals.

[0010] As a preferred embodiment of the present invention, the channel steel is provided with a plurality of reinforcing elbow plates, which are arranged along the height direction of the channel steel.

[0011] As a preferred embodiment of the present invention, a plurality of the reinforcing elbow plates are respectively disposed at the left and right ends of the channel steel and at the corresponding positions of the lifting lugs.

[0012] As a preferred embodiment of the present invention, the total length of the connecting fixture is 2m to 5m.

[0013] A method for rapid deployment of assembled railcars, employing a connecting fixture for assembled railcars, includes the following steps:

[0014] Step S1: Select the number of channel steel groups and the type of channel steel according to the layout design drawing of the ship's upper and lower track car groups;

[0015] Step S2: Fix the first connecting panel and the second connecting panel to the left and right ends of the channel steel respectively;

[0016] Step S3: After positioning the first railcar according to the layout design drawing of the ship's upper and lower railcar groups, connect the first connecting lug to the first railcar, connect the second connecting lug to the second railcar, and finally connect the first reinforcing lug and the first connecting lug to the first connecting lug through the first bolt and nut pair, and connect the second reinforcing lug and the second connecting lug to the second connecting lug through the second bolt and nut pair.

[0017] Step S4: Repeat step S3 until all the track trolleys are positioned.

[0018] As a preferred embodiment of the present invention, a method for rapid deployment of assembled railcar sets further includes step S5: after the ship's loading and unloading operations are completed, the connecting tooling is dismantled and recycled.

[0019] The rapid deployment method for assembled shipboard railcars provided by this invention has the following advantages compared with the prior art:

[0020] During connection, the specifications of the corresponding connecting fixtures are selected according to the actual layout design of the upper and lower railcars of the ship. The first connecting panel and the second connecting panel are first welded to the two adjacent railcars.

Detailed Implementation

[0030] 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.

[0031] In the description of this invention, it should be understood that the terms "upper," "lower," "left," "right," "front," "rear," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for 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. Therefore, they should not be construed as limitations on 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.

[0032] like Figures 1 to 5 As shown, a preferred embodiment of the present invention provides a connecting fixture 1 for an assembled railcar unit. The connecting fixture 1 is used to connect two adjacent railcars 2. It includes a channel steel 3, a first connecting panel 4, a second connecting panel 5, a first connecting lug 6, and a second connecting lug 7. The first connecting panel 4 and the second connecting panel 5 are respectively disposed at the left and right ends of the channel steel 3 and are fixedly connected to the channel steel 3. The first connecting lug 6 is connected to the first connecting panel 4 by a first bolt and nut pair 8, and the second connecting lug 7 is connected to the second connecting panel 5 by a second bolt and nut pair 9. The ends of the first connecting lug 6 and the second connecting lug 7 are provided with downwardly protruding welding portions for welding to the railcar 2.

[0033] For example, in order to facilitate the connection between the rail trolley 2 and the first connecting lug 6 or the second connecting lug 7, the rail trolley 2 is provided with a groove for the welding part to be inserted.

[0034] For example, the first connecting lug 6 has a first reinforcing lug 10 on the side away from the channel steel 3, and the second connecting lug 7 has a second reinforcing lug 11 on the side away from the channel steel 3. The shapes of the first reinforcing lug 10 and the second reinforcing lug 11 are the same as those of the first connecting lug 6 and the second connecting lug 7. The projected areas of both the first reinforcing lug 10 and the second reinforcing lug 11 are smaller than the projected areas of the first connecting lug 6 and the second connecting lug 7. Therefore, the first reinforcing lug 10 strengthens the first connecting lug 6, and the second reinforcing lug 11 strengthens the second connecting lug 7, thereby improving the connection strength of the connecting fixture 1 and ensuring the connection between the connecting fixture 1 and the track trolley 2.

[0035] For example, in order to prevent the nuts from loosening, anti-loosening washers 12 are provided between the nut of the first bolt and nut assembly 8 and the first reinforcing lug 10, and between the nut of the second bolt and nut assembly 9 and the second reinforcing lug 11.

[0036] For example, the channel steel 3 is provided with a plurality of lifting lugs 13, which are arranged at even intervals. This allows the channel steel 3 to be easily transferred by other transfer devices, making it convenient to use.

[0037] For example, in order to improve the strength of the channel steel 3, a plurality of reinforcing elbow plates 14 are provided on the channel steel 3. The reinforcing elbow plates 14 are arranged along the height direction of the channel steel 3, and the plurality of reinforcing elbow plates 14 are respectively arranged at the left and right ends of the channel steel 3 and at the corresponding positions of the lifting lugs 13.

[0038] In this embodiment, the total length of the connecting fixture is 2m to 5m. In practical use, different models of connecting fixtures 1 can be manufactured according to the actual type of ship to be used on different types of ships, which has a wide range of applications and high flexibility.

[0039] In this embodiment, the channel steel 3 is marked for easy identification.

[0040] like Figure 6 As shown, another aspect of the preferred embodiment of the present invention provides a method for the rapid deployment of assembled railcar units, comprising the following steps:

[0041] Step S1: Select the number of channel steel 3 groups and the type of channel steel 3 according to the layout design drawing of the ship's upper and lower track car groups;

[0042] Step S2: Fix the first connecting panel 4 and the second connecting panel 5 to the left and right ends of the channel steel 3 respectively;

[0043] Step S3: After positioning the first railcar 2 according to the layout design drawing of the ship's upper and lower railcar groups, connect the first connecting lug 6 to the first railcar 2, connect the second connecting lug 7 to the second railcar 2, and finally connect the first reinforcing lug 10 and the first connecting lug 6 to the first connecting lug 6 through the first bolt and nut pair 8, and connect the second reinforcing lug 11 and the second connecting lug 7 to the second connecting lug 7 through the second bolt and nut pair 9.

[0044] Step S4: Repeat step S3 until all the track trolleys 2 are positioned.

[0045] For example, a method for rapid deployment of assembled railcar units further includes step S5: after the ship's loading and unloading operations are completed, the connecting fixture 1 is removed and recycled.

[0046] A rapid deployment method for modular railcar units is adopted. During connection, the specifications of the corresponding connecting fixture 1 are selected according to the actual layout design drawing of the upper and lower railcar units on the ship. First, the first connecting panel 4 and the second connecting panel 5 are welded to the two adjacent railcars 2. Only the position of the first railcar 2 needs to be located, and the length of the channel steel 3 can be quickly positioned to the position of the second railcar 2. The first reinforcing ear plate 10, the first connecting ear plate 6, and the first connecting panel 4 are connected by the first bolt and nut pair 8. The second reinforcing ear plate 11, the second connecting ear plate 7, and the second connecting plate 8 are connected by the first bolt and nut pair 8. The connecting panels 5 are connected by the second bolt and nut pair 9, eliminating the need for repeated high-intensity repetitive operations such as welding and flame cutting in the upper and lower rows of the ship. It has the advantages of easy loading and unloading, portability, low manufacturing cost, simple manufacturing process, and standardized customized production, making it suitable for mass construction of the same type of ship. At the same time, the connecting tool 1 also has the functions of positioning and connecting force transmission, improving the efficiency of the layout of the upper and lower rows of the ship's railcar group. Using this invention, the position of the railcar trolley 2 can be quickly located, facilitating the disassembly and assembly of the connecting tool 1 and the railcar trolley 2 without repeated welding and flame cutting, thus improving construction efficiency.

[0047] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" 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.

[0048] 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.
