[0030] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0031] like Figures 1 to 3 As shown, an embodiment of the present application provides a launching beam 10, comprising a top plate 1, a bottom plate 2 and two side plates 3, the top plate 1 and the bottom plate 2 are arranged opposite to each other up and down and the two side plates 3 are connected and arranged between the top plate 1 and the bottom plate 2, the two side plates 3 are arranged opposite to each other and spaced apart, and there is a spacing between the side plates 3 and the edge of the top plate 1. A plurality of first ribs 8 arranged along the length direction of the top plate 1 are provided on the opposite sides of the two side plates 3, and a plurality of second ribs 9 arranged along the length direction of the top plate 1 are connected between the two side plates 3. The first ribs 8, the top plate 1 and the side plates 3 are arranged perpendicularly, and the second ribs 9, the top plate 1 and the side plates 3 are arranged perpendicularly. The two ends of the first rib 8 are connected to the top plate 1 and the bottom plate 2 respectively, and one end of the second rib 9 is connected to the top plate 1 and the other end is located between the top plate 1 and the bottom plate 2. A first reinforcing plate 5 is provided on one side of the middle of the bottom plate 2 close to the top plate 1, and the first reinforcing plate 5 is located between the two side plates 3. A first longitudinal bone assembly is provided on the side of the first reinforcing plate 5 away from the bottom plate 2, and the first longitudinal bone assembly is arranged in parallel with the side plates 3. By providing the above-mentioned first ribs 8, second ribs 9 and first longitudinal bone assembly in the launching cross beam, the overall support strength of the launching cross beam can be increased, and the use of sheet materials can be reduced, and the cost and weight of the launching cross beam can be reduced.

[0032] The launching beam 10 provided in this embodiment forms a frame structure by the top plate 1 and the bottom plate 2 opposite to each other, and the side plate 3 arranged between the top plate 1 and the bottom plate 2, wherein the side plate 3 is not arranged along the edge of the top plate 1 and the bottom plate 2, but forms a certain distance with the edge of the top plate 1 or the bottom plate 2, so that the first rib 8 is arranged at the spatial position outside the side plate 3, forming a frame structure as shown in FIG. Figure 3The structure shown increases the supporting capacity between the top plate 1 and the bottom plate 2 through the first rib 8, so that the launching beam 10 provided in this embodiment has a better supporting effect. The first rib 8 is arranged to extend from the top plate 1 to the bottom plate 2. The arranged first rib 8 has a good supporting effect, and the first rib 8 also serves to prevent the hull 14 from tipping over when in use.

[0033] The present embodiment further provides a second rib plate 9, through which the supporting effect of the launching beam 10 is enhanced. In the present embodiment, one end of the second rib plate 9 is provided starting from the top plate 1, and the other end is not connected to the bottom plate 2, forming a Figure 3 In the structure shown, one end of the second rib 9 is located between the top plate 1 and the bottom plate 2, and the second rib 9 is welded to the top plate 1 and the side plate 3, and is welded to the corresponding second longitudinal bone 6. In this embodiment, the ribs are divided into first ribs 8 and second ribs 9 for arrangement to support the launching beam 10 structure to increase the strength of the launching beam 10 structure. At the same time, the width of the first rib 8 is smaller than the width of the second rib 9. This arrangement can not only provide sufficient support for the launching beam 10, but also reduce the material usage of the ribs, save resources, and make the welding between the second rib 9 and other structures more convenient, reducing the process difficulty. Preferably, the width of the second rib 9 is set to 4-5 times the width of the first rib 8.

[0034] In this embodiment, a first reinforcing plate 5 is further provided in the middle of the bottom plate 2. The first reinforcing plate 5 and the bottom plate 2 are parallel and fitted to each other, and the width of the first reinforcing plate 5 is 1 / 2-2 / 3 of the spacing between the two side plates 3, so as to strengthen the bottom plate 2. A first longitudinal bone assembly is further connected to the first reinforcing plate 5 to further strengthen the bottom plate 1. The first longitudinal bone assembly includes at least two first longitudinal bones 7 spaced apart along the width direction of the top plate 1, and the first longitudinal bones 7 are plate-shaped structures.

[0035] The present embodiment provides a launching beam 10, which provides sufficient support for the bow and stern of the hull 14 when the hull 14 is sliding into the water, so that the bow and stern of the hull 14 will not be deformed or displaced during the sliding launching process; when the launching beam 10 is in use, it is bound to the hull 14 by structures such as cables, and the launching beam 10 carries the hull 14 for sliding launching. After the hull 14 is completely launched into the water, the cables are untied to separate the launching beam 10 from the hull 14. The launching beam 10 is easy to use and has good supporting capacity.

[0036] Furthermore, the base plate 2 includes a first support portion 21, a second support portion 22 and two connecting portions 23. The two second support portions 22 are respectively arranged on both sides of the first support portion 21 and are connected to the first support portion 21 through the connecting portions 23. The second support portion 22 is used for sliding cooperation with the slide 12. The first longitudinal bone assembly is arranged on the first support portion. The distance between the first support portion 21 and the top plate 1 is greater than the distance between the second support portion 22 and the top plate 1.

[0037] like Figure 1 As shown, the bottom plate 2 provided in this embodiment is set to a structure with a low middle and high two ends, the two ends are second support parts 22, the second support part 22 is the position that contacts with the slideway 12 for sliding, the middle is the first support part 21, the top plate 1 at the position of the first support part 21 contacts with the hull 14, and a longer rib structure is set for support, the first support part 21 and the second support part 22 are connected by a connecting part 23, and the connecting part 23 can be in the form of a plane, or set in the form of other smooth transitions such as an arc. In this embodiment, the height of the launching beam 10 at the position of the first support part 21 is set higher, and the height of the launching beam 10 at the position of the second support part 22 is set higher, so that the support capacity for the hull 14 is better. At the same time, when the second support part 22 slides on the slideway 12, the first support part 21 is located in the middle of the two slideways 12, and the process of the launching beam 10 carrying the hull 14 to slide is more stable and not prone to tilting.

[0038] like Figure 3 As shown, in this embodiment, the first reinforcing plate 5 is arranged at the portion where the first supporting portion 21 of the bottom plate 2 is located, and the first reinforcing plate 5 is extended along the length direction of the first supporting portion 21. Since the distance between the bottom plate 2 and the top plate 1 at the first supporting portion 21 is larger than that at other places, the length of the first reinforcing plate 5 is set as much as possible to be the same as the length of the first supporting portion 21 of the bottom plate 2, so as to improve the strength of the bottom plate 2. At the same time, a plurality of first longitudinal bones 7 are connected to the first reinforcing plate 5. In this embodiment, two first longitudinal bones 7 are connected to the first reinforcing plate 5 according to the distance between the two side plates 3. The first longitudinal bones 7 are parallel to the side plates 3 and extend along the length direction of the first supporting portion 21 of the bottom plate 2, preferably the same length as the first supporting portion 21, so as to also strengthen the strength of the bottom plate 2. Among them, the first longitudinal bones 7 and the first reinforcing plate 5 are welded.

[0039] Optionally, the first longitudinal bone assembly is located on a side of the second rib plate 9 disposed on the first support portion 21 away from the top plate 1 , and there is a gap between the first longitudinal bone assembly and the second rib plate 9 .

[0040] In this embodiment, a second rib 9 is provided between the top plate 1 and the bottom plate 2. The second rib 9 is not a structure extending from the top plate 1 to the bottom plate 2. Its height is the height of the launching beam 10, which is about 1 / 2 of the distance between the top plate 1 and the bottom plate 2. The end of the second rib 9 not connected to the top plate 1 is not connected to the first longitudinal bone 7. Therefore, the second rib 9 does not need to be welded to the first longitudinal bone 7. While the second rib 9 plays a supporting and reinforcing role, the process at this position is also relatively simple.

[0041] like Figure 4 As shown is a schematic diagram of the application process of the launching beam 10 in this embodiment, a slideway 12 is arranged on the ground, a spacing is provided in the middle of the slideway 12, the launching beam 10 is bound to the hull 14 through cables, and the launching beam 10 and the hull 14 are buffered by pads 13, the launching beam 10 is overlapped on the slideway 12, slides on the slideway 12, carries the hull 14 into the water, and provides certain support to the bow and stern of the hull 14 to ensure that the bow and stern positions of the hull 14 are not deformed or displaced.

[0042] Optionally, both the first supporting portion 21 and the second supporting portion 22 are provided with a plurality of first ribs 8 and a plurality of second ribs 9 .

[0043] In this embodiment, the strength of the entire launching beam 10 is strengthened by arranging the first rib 8 and the second rib 9 between the top plate 1 and the bottom plate 2, so that the launching beam 10 can meet the required support for the hull 14, and the number of the first rib 8 and the second rib 9 is large, and good and effective support is provided through the large number of rib structures arranged at intervals. Figure 2 As shown, the first ribs 8 and the second ribs 9 at the same position in this embodiment are arranged at the same width, that is, the first ribs 8 and the second ribs 9 at each position are in the same plane. Since the bottom plate 2 is arranged as the first support portion 21 and the second support portion 22 in this embodiment, the first ribs 8 and the second ribs 9 need to be arranged on the first support portion 21 and the second support portion 22, respectively. The strength support of the first support portion 21 and the second support portion 22 is achieved by multiple groups of first ribs 8 and second ribs 9. Preferably, four groups of rib structures are arranged on each second support portion 22 and each first support portion 21. The intervals between the ribs on the first support portion 21 are the same. At least one group of ribs on the second support portion 22 is arranged at the connection point between the second support portion 22 and the connection portion 23. The other three groups of rib structures are evenly spaced and distributed on the second support portion 22, forming a structure as shown in FIG. Figure 1 The rib distribution form shown.

[0044] Furthermore, it also includes: a second reinforcing plate 4, which is fitted on the side of the top plate 1 close to the bottom plate 2, and the second reinforcing plate 4 is located between the two side plates 3 and extends along the length direction of the top plate 1; a second longitudinal bone assembly, which is arranged on the side of the second reinforcing plate 4 away from the top plate 1, and the second longitudinal bone assembly is arranged parallel to the side plate 3, and the second longitudinal bone assembly includes at least two second longitudinal bones 6 arranged at intervals along the width direction of the top plate 1.

[0045] like Figure 3 As shown, in this embodiment, a second reinforcing plate 4 is also arranged on the top plate 1, which is parallel to the top plate 1 and arranged in contact with each other, and the width of the second reinforcing plate 4 is 1 / 2-2 / 3 of the spacing between the two side plates 3, so as to strengthen the top plate 1. The second reinforcing plate 4 is extended along the length direction of the top plate 1, and is set as much as possible to be the same length as the top plate 1, so as to improve the strength of the top plate 1 as a whole. At the same time, a second longitudinal bone assembly is also connected to the second reinforcing plate 4. In this embodiment, two second longitudinal bones 6 are connected to the second reinforcing plate 4 according to the spacing between the two side plates 3. The second longitudinal bones 6 are parallel to the side plates 3 and extend along the length direction of the top plate 1, preferably the same length as the top plate 1, so as to strengthen the strength of the top plate 1. Under this structure, the second longitudinal bones 6 are welded to the second reinforcing plate 4, and the second longitudinal bones 6 are also connected to the second rib 9 by welding, so that a criss-cross reinforcing rib structure is formed inside the launching cross beam 10, and the formed launching cross beam 10 has high strength and support capacity for the hull 14. The second longitudinal bone 6 is a plate-like structure, and is arranged in multiple sections with gaps between adjacent sections to avoid the second ribs 9, and the second longitudinal bone sections located on both sides of the second ribs 9 are welded to the second ribs 9. Each second rib 9 is provided with an avoidance gap at one end close to the top plate 1 to allow the second reinforcing plate 4 to pass through.

[0046] Preferably, the plurality of first longitudinal bones 7 and the plurality of second longitudinal bones 6 are arranged in one-to-one correspondence, and the corresponding first longitudinal bones 7 and second longitudinal bones 6 are formed on the same plane.

[0047] Further, a plurality of first ribs 8 located on the side of each side plate 3 away from the second rib 9 are penetrated with connecting rods, specifically: a plurality of first ribs 8 located on the side of each side plate 3 away from the second rib 9 are provided with through holes, the connecting rod is penetrated through the plurality of through holes and the two ends extend out of the two outermost through holes respectively, the two ends of the connecting rod are screwed with nuts and the nuts are in abutment with the first ribs 8, it should be understood that the plurality of first ribs 8 located on the side of each side plate 3 away from the second rib 9 include the first ribs 8 located on the second supporting portion. The connecting rod can strengthen the bending resistance of the launching beam and improve the deformation capacity of the launching beam.

[0048] Furthermore, it also includes:

[0049] The sealing plate 15 is arranged at the end of the side plate 3 and connected to both the top plate 1 and the bottom plate 2;

[0050] The hanging plate 11 is installed on the sealing plate 15 and is provided with a through hole for being tied to the hull 14 to be moved.

[0051] like Figure 1 As shown, sealing plates 15 are provided at both ends of the launching beam 10 in this embodiment, so that the structure forms a relatively closed beam structure, and the sealing plates 15 at both ends also play a supporting role for the top plate 1 and the bottom plate 2 to a certain extent. A hanging plate 11 is also provided on the sealing plate 15, and the hanging plate 11 has a through hole for the cable to pass through to achieve binding with the hull 14. Preferably, two hanging plates 11 are provided on each sealing plate 15, and the two hanging plates 11 are relatively parallel, and the surface where the hanging plate 11 is located is parallel to the surface where the side plate 3 is located.
