DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the protection scope of the present invention.

[0022] like Figure 1 As shown, the lifting and flipping trailer includes a body 1 and a cabin 2. The upper part of the left side plate or the right side plate of the cabin 2 is rotatably connected to the body 1 through a rotating shaft 140. The rotating shaft 140 is arranged along the front and rear direction of the body 1. A flipping cylinder 130 is hinged between the body 1 and the cabin 2. The flipping cylinder 130 is actuated to rotate the cabin 2 around the rotating shaft 140. After the cabin 2 is flipped, the goods inside can slide out from the opening, and the goods can be unloaded to a lower position, such as unloading into a relatively low car, or directly falling to the ground, the cabin 2 can be directly flipped to unload the goods.

[0023] It should be noted that in this application, the end where the traction frame 150 is set is the front, the end away from the traction frame 150 is the rear, the side away from the reader of the other two sides is the left, and the side close to the reader is the right. The left and right sides of the rotating shaft 140 set in the compartment 2 are all included in the scope of protection of this application. In the following description, the rotating shaft 140 is set on the left side plate 201 of the compartment 2, and when unloading, the compartment 2 is flipped to the left as an example.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown together, the vehicle body 1 includes a lifting frame 110 arranged on the left or right side. In the present application, the lifting frame 110 is arranged on the left side of the vehicle body 1. The top of the lifting frame 110 is rotatably connected to the vehicle compartment 2 through the rotating shaft 140. The lifting frame 110 can drive the vehicle compartment 2 to move up and down relative to the vehicle body 1. The lower end of the tilting cylinder 130 is hinged to the lifting frame 110. When preparing to unload, the vehicle compartment 2 is first raised by driving the lifting frame 110, and the tilting cylinder 130 is then actuated to tilt the vehicle compartment 2 to the left, so that the goods in the vehicle compartment 2 slide out. The vehicle compartment 2 is first raised before being tilted, so that the goods can be unloaded at a higher position. When two vehicles are unloading side by side and the vehicle compartment receiving the goods is higher, it can avoid interference between the vehicle compartment 2 and the vehicle compartment receiving the goods when it is tilted.

[0025] Specifically, the lifting frame 110 includes a guide rail assembly and a lifting cylinder 113. The guide rail assembly includes an outer guide rail 111 and an inner guide rail 112 that are slidably connected. The outer guide rail 111 is obliquely installed on one side of the vehicle body 1, and the rotating shaft 140 is installed on the top of the inner guide rail 112. The two ends of the lifting cylinder 113 are respectively hinged to the outer guide rail 111 and the inner guide rail 112.

[0026] like Figure 3 As shown, in this embodiment, two guide rail assemblies and two lifting cylinders 113 are provided, the vehicle compartment 2 is provided between the two guide rail assemblies, and the lifting cylinder 113 is provided on the side of the guide rail assembly away from the vehicle compartment 2. Two tilting cylinders 130 are provided and are respectively located at the front and rear sides of the vehicle compartment 2, one end of the tilting cylinder 130 is hinged to the inner guide rail 112, and the other end is hinged to the front or rear side of the vehicle compartment 2 away from the rotating shaft 140.

[0027] This structure can ensure that the forces applied to the front and rear of the cabin 2 are balanced during the flipping process, ensuring that the cabin 2 moves stably front and back during the lifting and flipping process. And because the cabin 2 and the flipping cylinder 130 are both installed on the inner guide rail 112, the force generated by the flipping cylinder 130 and the gravity of the cabin 2 offset each other on the inner guide rail 112 during the flipping process. Conventional trailers are unloaded by flipping through the cylinder hinged between the body 1 and the cabin 2. When the cylinder is in motion, it will generate a squeezing force on the body 1 through the cabin 2. Therefore, the structure of the present application can avoid the generation of squeezing force on the body 1, reduce damage to the body 1, and extend the service life.

[0028] Figure 1 The figure shows the original state of the trailer of the present application. When unloading, the lifting cylinder 113 is first extended to lift the compartment 2 upward. After reaching the set height, the lifting cylinder 113 stops moving; then, the flipping cylinder 130 is extended, and the compartment 2 is rotated around the rotating shaft 140 so that the opening faces the lower side to carry out unloading; after unloading, the flipping cylinder 130 and the lifting cylinder 113 are retracted in turn, and the compartment 2 returns to its original position.

[0029] like Figure 3 As shown, the lifting frame 110 further includes a reinforcing structure 120 connected between the two guide rail assemblies and between the outer guide rail 111 and the vehicle body 1 , which can enhance the structural strength of the lifting frame 110 .

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a plurality of counterweights 101 are detachably mounted on the right side of the vehicle body 1 opposite to the lifting frame 110. The number of counterweights 101 is adjusted according to the weight of the cargo in the vehicle compartment 2 to adjust the center of gravity of the trailer as a whole to avoid the vehicle body 1 from tipping over when unloading.

[0031] The warehouse 2 is formed by a plurality of warehouse plates fixed and spliced ​​by bolts, which is convenient for container transportation. The left side plate 201 and the right side plate of the warehouse 2 are both tilted outward, so that the goods can slide out of the warehouse 2 without turning over too much angle, which is convenient for unloading. Moreover, the small turning angle of the warehouse 2 has small requirements on the structure and strength of the vehicle body 1, which is easy to implement. The warehouse plate close to the lifting frame 110, that is, the left side, is higher than the other sides of the warehouse 2 and the rotating shaft 140. The upper end of the left warehouse plate extends a long distance. When the warehouse 2 is turned over, its upper edge can extend above the receiving warehouse 2. When unloading, the two vehicles do not need to be too close, so it is not easy to collide, and the safety is higher.

[0032] like Figure 3 As shown, the front end of the vehicle body 1 is connected to a traction frame 150, which is used to be connected to a tractor to provide power for the trailer. The traction frame 150 is provided with support legs 151 that can adjust the distance between the traction frame 150 and the ground to prevent the traction frame 150 from falling to the ground. The bottom of the support legs 151 is provided with rollers so that the trailer can move without traction.

[0033] The utility model discloses a lifting and flipping trailer which is connected to the vehicle body by rotating the upper part of the left side plate or the right side plate of the vehicle compartment through a rotating shaft. The rotating shaft is arranged along the front and rear direction of the vehicle body. When unloading, the two vehicles are arranged side by side. The action of the flipping oil cylinder can rotate the vehicle compartment around the rotating shaft to flip the vehicle compartment sideways for unloading. When the receiving vehicle compartment is full, the vehicle can be started to move forward and backward to continue unloading, which is convenient for unloading while moving the vehicle on the road.

[0034] In the description of this specification, it should be understood that the descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0035] In the description of this specification, unless otherwise clearly defined, words such as "setting", "installation", and "connection" should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meaning of the above words in this utility model based on the specific content of the technical solution.

[0036] Although the specific implementation methods of the utility model are described above, those skilled in the art should understand that the described embodiments are only part of the implementation methods of the utility model, rather than all the implementation methods, which are only examples, and the protection scope of the utility model is defined by the claims. Those skilled in the art can make various changes or modifications to these implementation methods without departing from the principle and essence of the utility model and without any creative work, but these changes and modifications fall within the protection scope of the utility model.
