[0002] In the process of transporting oversized and large items, it is generally necessary to connect the tractor and the trailer through a traction device. After traction, a connection operation is formed, and the tractor can drive the trailer to move, so that the trailer can drive the oversized and large items to be transported during the movement;

[0003] In actual use, when encountering potholes, the trailer will move up and down continuously, so the traction device also operates in linkage, and the tractor drives the trailer to turn, which will generate a large amount of turning force, thus driving the trailer to rotate at an angle, and when turning, due to the large turning force, the traction device will be subjected to a large turning force, which will easily cause the traction device to deform and damage, and have poor durability and poor pressure resistance;

[0004] Therefore, it is particularly important to design a new multi-degree-of-freedom traction device to solve the above-mentioned technical defects and improve the practicality of the overall multi-degree-of-freedom traction device. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-degree-of-freedom traction device for large-piece transportation, which can prevent overload or damage to parts in the vertical direction during the transportation of oversized large pieces, thereby improving the applicability of the traction device. When transporting large pieces, after the tractor or trailer stops moving, the impact caused by inertia causes the first connecting column and the second connecting column to slide into the connecting sleeve and be buffered by the buffer spring, thereby improving the protection of the traction device and the overall safety of the air duct assembly, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0025] A multi-degree-of-freedom traction device for large-piece transportation, comprising a traction plate 1, the front of the traction plate 1 is connected to a first connecting frame 3 through a connecting assembly 2, the first connecting frame 3 is connected to a second connecting frame 5 through a movable assembly 4, and the front of the second connecting frame 5 is fixedly connected to two groups of connecting plates 6;

[0026] Specifically, the first connecting frame 3 is first installed on the front side of the traction plate 1 through the connecting component 2, and the second connecting frame 5 is installed on the front side of the first connecting frame 3 through the movable component 4. The traction plate 1 is installed on the tractor, and the two groups of connecting plates 6 on the front side of the second connecting frame 5 are installed on the trailer. When in use, the connecting component 2 can be buffered by the buffer spring, thereby reducing the impact of the impact force on the traction device, thereby increasing the service life of the traction device and ensuring the safety of transportation. At the same time, the movable component 4 allows the first connecting frame 3 and the second connecting frame 5 to rotate at different angles, thereby improving the use effect.

[0027] Also, see Figure 1 and Figure 2 , the front side of the traction plate 1 is connected to a first connecting frame 3 through a connecting assembly 2;

[0028] The connecting assembly 2 is used for the stable connection between the traction plate 1 and the first connecting frame 3. The specific structure of the connecting assembly 2 is as follows:

[0029] The connecting assembly 2 includes two groups of first connecting blocks 201, a rotating block 202, a second connecting block 203, a first connecting column 204, a second connecting column 205 and a connecting sleeve 206. The two groups of first connecting blocks 201 are both rotatably connected to the front side of the traction plate 1. The two groups of first connecting blocks 201 are respectively rotatably connected to the second connecting blocks 203 through the two groups of rotating blocks 202. The first connecting column 204 is fixedly connected to the front side of the traction plate 1 and located between the two groups of first connecting blocks 201. The second connecting column 205 is fixedly connected to the back side of the first connecting frame 3 and located between the two groups of first connecting blocks 201. A connecting sleeve 206 is slidably connected between the first connecting column 204 and the second connecting column 205. The two groups of second connecting blocks 203 are both rotatably connected to the back side of the first connecting frame 3 and located on the left and right sides of the second connecting column 205.

[0030] Specifically, buffer springs are provided inside the connecting sleeve 206 and at positions corresponding to the first connecting column 204 and the second connecting column 205, and both sets of buffer springs are equipped with dampers. After the tractor and the trailer are connected by the traction device, when the tractor and the trailer stop during the transportation of oversized large items, the impact force caused by inertia moves into the connecting sleeve 206 through the first connecting column 204 and the second connecting column 205, and then is buffered by the buffer spring, thereby reducing the impact of the impact force on the traction device. At the same time, the first connecting block 201 and the second connecting block 203 are rotated by the two sets of rotating blocks 202, thereby increasing the service life of the traction device and ensuring the safety of transportation.

[0031] Then, the first connecting frame 3 is connected to the second connecting frame 5 through the movable component 4;

[0032] See also Figure 1 and Figure 3 The movable assembly 4 is used for movable connection between the first connecting frame 3 and the second connecting frame 5:

[0033] The movable assembly 4 includes two sets of first rotating plates 401, a connecting shaft 402, a movable plate 403, a second rotating plate 404, a sleeve rotating seat 405, a reinforcing rod 406, a first limiting screw 407 and a second limiting screw 408. The two sets of first rotating plates 401 are fixedly connected to the back of the first connecting frame 3. The two sets of first connecting frames 3 are rotatably connected to the movable plate 403 through the connecting shaft 402. The back of the second connecting frame 5 and the left and right sides of the movable plate 403 are fixedly connected. A second rotating plate 404 is connected, and two groups of second rotating plates 404 are rotatably connected to the movable plate 403 through a socket rotating seat 405. A reinforcing rod 406 is rotatably connected between the two groups of second rotating plates 404 and in front of the movable plate 403. The two groups of socket rotating seats 405 are respectively connected to the two groups of second rotating plates 404 through two groups of first limiting screws 407, and the two groups of socket rotating seats 405 are respectively connected to the movable plate 403 through two groups of second limiting screws 408.

[0034] Specifically, the first connecting frame 3 and the second connecting frame 5 are movably connected through the movable component 4. After the tractor is connected to the trailer by using the traction device, the first connecting frame 3 can be rotated with the movable plate 403 through two groups of first rotating plates 401 and two groups of connecting shafts 402. The movable plate 403 can be rotated with the second rotating plate 404 through the sleeve rotating seat 405. At this time, one end of the movable plate 403 is installed with the two groups of second rotating plates 404 through two groups of first limiting screws 407, and the other end of the movable plate 403 is installed with two groups of second limiting screws 408. The reinforcing rod 406 improves the connection strength between the two groups of second rotating plates 404.

[0035] In this embodiment, the implementation scenario is specifically as follows: in actual use, the first connecting frame 3 is first installed on the front side of the traction plate 1 through the connecting component 2, and the second connecting frame 5 is installed on the front side of the first connecting frame 3 through the movable component 4. When the traction plate 1 is installed on the tractor, the two groups of connecting plates 6 on the front side of the second connecting frame 5 are installed on the trailer. When in use, the connecting component 2 can be buffered by the buffer spring, thereby reducing the impact of the impact force on the traction device, thereby increasing the service life of the traction device and ensuring the safety of transportation. At the same time, the movable component 4 allows the first connecting frame 3 and the second connecting frame 5 to rotate at different angles, thereby improving the use effect. Compared with the existing multi-degree-of-freedom traction device, the utility model can improve the overall practicality of the multi-degree-of-freedom traction device through design.
