Description

Technical Field

[0001] The utility model relates to the technical field of trailers, in particular to a flatbed trailer with a bracket. Background Art

[0002] During the manufacturing, water testing and maintenance of ships, it is often necessary to move the ships from land to water, or from water to land. However, the ships are large in size and length, making movement difficult. Therefore, the movement of the ship is often achieved through lifting devices or mobile trailers.

[0003] The existing inland river boats include flat-bottom boats and pointed-bottom boats. For flat-bottom boats, traditional flatbed trailers are sufficient to achieve stable support for them; but for pointed-bottom boats with a certain curvature on the bottom surface of the bow or stern, traditional flatbed trailers obviously cannot meet the requirements of stable support for them. Therefore, some researchers in this field have designed mobile trailers for pointed-bottom boats, such as the Chinese patent with publication number CN103313878B, which discloses a boat trailer with at least two holes, and the trailer includes a transport part and a load-bearing part. The load-bearing part includes at least two columns protruding from the transport part. The protruding end of each column is connected or received by a boat clamping part, and the size of the boat clamping part gradually decreases as it moves away from the transport part. When the boat clamping part is received by one of the at least two holes, at least a part of the boat clamping part is compressed and deformed, and a friction connection is formed between a part of the boat clamping part and the hole. The above-mentioned boat trailer has poor universal performance and is only suitable for small recreational boats with two engaging holes, and it is difficult to meet the demand for supporting and transferring various types of inland river boats with larger volumes and richer types.

[0030] like Figure 1-Figure 4 As shown, the utility model provides a flatbed trailer 100 with a bracket, comprising a flatbed trailer 110 and at least two brackets 120 for supporting a ship 200, wherein the brackets 120 are symmetrically arranged on the left and right sides of the upper end surface of the flatbed trailer 110, and the brackets 120 can adaptively adjust the height and angle according to the bottom shape of the ship 200. Figure 2 As shown, in some embodiments, the two brackets 120 may be parallel to the upper and lower sides of the flatbed trailer 110. Figure 3 As shown, in some embodiments, the two brackets 120 may also form a certain angle with the upper and lower sides of the flatbed trailer 110. Figure 4 As shown, in some embodiments, there may be four brackets 120, and the four brackets 120 are symmetrically arranged on the upper end surface of the flatbed trailer 110 in pairs, and the brackets 120 are parallel to the upper and lower sides of the flatbed trailer 110 to provide more stable support. Although not shown in the figure, the four brackets 120 may also form a certain angle with the upper and lower sides of the flatbed trailer 110. Therefore, no matter how many brackets 120 are arranged, and whether the brackets 120 are parallel to the upper and lower sides of the flatbed trailer 110, it is only necessary to ensure that the brackets 120 on the left and right sides are symmetrically arranged to ensure that the flatbed trailer 100 with brackets can stably support the ship 200.

[0031] The flatbed trailer 110 may be a trackless flatbed trailer or a tracked flatbed trailer, both of which are common flatbed trailers on the market, and the specific structure will not be described here.

[0032] The bracket 120 includes a first telescopic arm 121, a second telescopic arm 122, a third telescopic arm 123 and a support plate 125. The fixed ends of the first telescopic arm 121, the second telescopic arm 122 and the third telescopic arm 123 are sequentially installed on the upper end surface of the flatbed trailer 110 from the inside to the outside, and the first telescopic arm 121, the second telescopic arm 122 and the third telescopic arm 123 are arranged in a collinear manner; the movable ends of the first telescopic arm 121, the second telescopic arm 122 and the third telescopic arm 123 are respectively connected to the support plate 125, the first telescopic arm 121 and the second telescopic arm 122 are jointly connected to one end of the support plate 125, and the third telescopic arm 123 is separately connected to the other end of the support plate 125.

[0033] like Figure 4 As shown, in some embodiments, when the number of the brackets 120 disposed on the same side of the flatbed trailer 110 is greater than or equal to two, the plurality of brackets 120 may be respectively provided with the support plates 125. Figure 5 As shown, in other embodiments, when the number of the brackets 120 disposed on the same side of the flatbed trailer 110 is greater than or equal to two, the plurality of brackets 120 may share the pallet 125 .

[0034] Furthermore, the first telescopic arm 121, the second telescopic arm 122, and the third telescopic arm 123 can be hydraulic telescopic rods, which have the characteristics of large output force and high load, can ensure stable support of ships with large mass, and are more reliable and safer than pneumatic telescopic rods.

[0035] Furthermore, in order to ensure the flexibility of angle adjustment when the first telescopic arm 121, the second telescopic arm 122 and the third telescopic arm 123 are telescopically extended or retracted, the fixed ends of the first telescopic arm 121, the second telescopic arm 122 and the third telescopic arm 123 can be rotatably connected to the flatbed trailer 110 through a first ear plate 127, and the movable end of the third telescopic arm 123 can be rotatably connected to the support plate 125 through the first ear plate 127; the movable end of the first telescopic arm 121 can first be rotatably connected to the movable end of the second telescopic arm 122 through a Y-shaped joint 124, and the Y-shaped joint 124 and the movable end of the second telescopic arm 122 are then rotatably connected to the support plate 125 through a second ear plate 128; the length of the second ear plate 128 is greater than the length of the first ear plate 127 to obtain a larger angle adjustment range.

[0036] Furthermore, in order to prevent the paint surface of the ship 200 from being scratched by the metal support plate 125, a cushion block 126 may be fixed on the support plate 125. The cushion block 126 has a certain rigidity and elasticity and may be a wooden block or a rubber block.

[0037] Please review Figure 1 and Figure 5 The working process of the flatbed trailer 100 with a bracket provided by the utility model is as follows: when the bracket 120 supports the pointed bottom of the bow or stern of the ship 200, the movable ends of the first telescopic arm 121, the second telescopic arm 122 and the third telescopic arm 123 are first extended together to lift the support plate 125 and the cushion block 126 upwards; when the cushion block 126 on one side of the first telescopic arm 121 and the second telescopic arm 122 first contacts the pointed bottom of the bow or stern of the ship 200, the movable ends of the first telescopic arm 121 and the second telescopic arm 122 stop extending, while the movable end of the third telescopic arm 123 continues to extend, and with the connection between the first telescopic arm 121 and the second telescopic arm 122 and the support plate 125 as a fulcrum, the other ends of the support plate 125 and the cushion block 126 continue to be lifted upwards until the two brackets 120 jointly complete the clamping of the pointed bottom of the bow or stern of the ship 200.

[0038] Therefore, the utility model effectively overcomes various shortcomings in the prior art and has a high industrial utilization value. The above embodiments are only illustrative of the principles and effects of the utility model, and are not used to limit the utility model. Anyone familiar with this technology can modify or change the above embodiments without violating the spirit and scope of the utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed by the utility model should still be covered by the claims of the utility model.
