Description

Technical Field

[0001] This utility model relates to the field of large-scale logistics and transportation equipment, and in particular to a detachable saddle. Background Technology

[0002] Existing large, horizontal, modular box-type flatbed trucks generally use an integral saddle.

[0003] The advantages of this type of saddle are its simple structure, light weight, and ease of production and processing. However, its disadvantages are that when the production area space is limited, the saddle is not easy to follow the car platform to reach the bottom of the goods. It is necessary to pre-embed lifting lugs on the goods and then hoist the saddle onto the goods. Another mode is to use a smaller saddle. The advantage of this type of saddle is that it is easy to produce and use. However, its disadvantages are that the contact surface is smaller, the transportation stability is poor, accidents are more likely to occur, and the load-bearing capacity is poor. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology by providing a detachable saddle that offers stable transport, high load-bearing capacity, and strong stress resistance, exhibiting strong stress resistance both during transport on a flatbed and on a support. It is easy to install and disassemble in confined spaces, saving loading and unloading time; its simple structure makes it convenient to operate.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] This utility model provides a detachable saddle, which is U-shaped and includes an upper saddle and a lower saddle, which are connected by high-strength bolts.

[0007] The upper saddle has a boss on its bottom surface and a threaded hole on its side. The lower saddle has a groove on its top surface and a through hole on the side wall of each groove. The boss of the upper saddle fits into the groove of the lower saddle, so that the threaded hole on the side of the boss of the upper saddle corresponds to the through hole on the side wall of the groove of the lower saddle. After being fastened by passing through the through hole and the threaded hole with a high-strength bolt, the saddle is formed as a whole.

[0008] Furthermore, the saddle is made of Q345B material.

[0009] Furthermore, the total weight of the saddle is 8.9 tons.

[0010] Furthermore, the boss of the upper saddle and the groove of the lower saddle are connected by a sliding groove and a slider. The top of the boss is arc-shaped and the bottom of the groove is arc-shaped, which makes it convenient to align the bolt holes when assembling the saddles.

[0011] Furthermore, the distance between the two left and right protrusions of the upper saddle is equal to the distance between the two left and right grooves on the top surface of the lower saddle; the height of the protrusion is less than or equal to the depth of the groove.

[0012] Furthermore, a fixing plate can be installed on either of the two protrusions on the bottom surface of the upper saddle. The fixing plate has a round hole, and the fixing plate is fixed to the protrusion of the upper saddle through the round hole and the pin.

[0013] Furthermore, the fixing plate is provided with 1 to 3 process holes, and the diameter of the pin is equal to the diameter of the process hole.

[0014] Furthermore, the saddle is equipped with an anti-slip pad.

[0015] Furthermore, the saddle also includes reinforcing ribs, which are welded or riveted to the upper and lower saddles to improve the strength of the saddle.

[0016] Furthermore, the saddle is also equipped with lifting lugs for lifting the entire saddle, facilitating operations within the factory area.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] (1) Easy to install and disassemble, saving loading and unloading time;

[0019] (2) Simple structure and easy to operate;

[0020] (3) It has a large load capacity and strong stress resistance, and has a strong stress resistance in both the vehicle transport state and on the support pier.

[0021] (4) High flexibility: When used in a factory, the adjustable height of the roller frame is limited, and the lifting height of the platform is also limited. In existing technologies, if the platform is not detachable, the entire saddle may be unable to reach under the cargo due to space constraints. This saddle is detachable on one side, allowing the platform to first carry the saddle body under the cargo, and then fix the support on the other side. This allows the operation to be completed within a smaller height range, providing high flexibility. Attached Figure Description

Component models, material names, connection structures, control methods, algorithms, and other features not explicitly described in this technical solution are considered common technical features disclosed in the prior art.

[0031] Example 1

[0032] This embodiment provides a detachable saddle, such as Figure 1 As shown, the saddle is U-shaped and includes an upper saddle 1 and a lower saddle 2, which are connected by high-strength bolts.

[0033] The upper saddle 1 has a boss on its bottom surface and a threaded hole on its side. The lower saddle 2 has a groove on its top surface and a through hole on the side wall of each groove. The boss of the upper saddle 1 fits into the groove of the lower saddle 2, so that the threaded hole on the side of the boss of the upper saddle 1 corresponds to the through hole on the side wall of the groove of the lower saddle 2. After being fastened by passing through the through hole and the threaded hole with a high-strength bolt, an integral saddle is formed.
