Description

Technical Field

[0001] The utility model belongs to the technical field of trailers, and in particular relates to a lightweight trailer with pneumatic outriggers. Background Art

[0002] A trailer is a vehicle towed by a car but without its own power drive device. It is a combination of a car (truck or tractor, forklift) and one or more trailers. The truck and tractor are the driving sections of the car train, called the main car, and the driven section towed by the main car is called the trailer. It is an important type of vehicle for road transportation. Using car train transportation is the most effective and simple means to improve economic efficiency.

[0003] The function of the trailer outrigger is to support the ground when the tractor is uncoupled from the trailer and to bear the load of the front half of the trailer. Referring to a semi-trailer pneumatic outrigger with a reference to announcement number CN219192162U, the outrigger is fixedly mounted on the frame during use. When the road surface is uneven, the position of the outrigger cannot be adjusted. When the outrigger is supporting, unbalanced force will occur, which can easily cause the vehicle to become unbalanced, making it inconvenient to use. Utility Model Content

[0019] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1

[0021] like Figure 1 - Figure 5 As shown, a lightweight trailer with pneumatic legs includes a trailer body 1 and a connecting frame 2 installed on one side of the trailer body 1, a fixed cylinder 3 is installed at the bottom of the connecting frame 2 through a sliding mechanism, two moving plates 4 are slidably connected inside the fixed cylinder 3, the sides of the two moving plates 4 that are away from each other extend to the outside of the fixed cylinder 3, and the bottoms of the two moving plates 4 are installed with supporting mechanisms, and a moving mechanism for driving the two moving plates 4 to move closer to or away from each other is installed inside the fixed cylinder 3, and the moving mechanism includes a moving groove opened inside the moving plate 4, a slide plate 10 connected to the inside of the moving groove, and a threaded rod 16 installed on one side of the slide plate 10, one end of the threaded rod 16 passes through the moving plate 4 and extends to the inside of the fixed cylinder 3, and a rotating machine for driving the threaded rod 16 to rotate is installed inside the fixed cylinder 3 The rotating mechanism includes a first bevel gear 13 arranged on one side of the inner wall of the fixed cylinder 3, a second bevel gear 14 installed at one end of the threaded rod 16 and meshing with the first bevel gear 13, and a rotating motor 15 driving the first bevel gear 13 to rotate is installed on the outside of the fixed cylinder 3. The supporting mechanism includes a pneumatic cylinder 6 installed at the bottom of the movable plate 4, a rotating block 7 rotatably connected to the output end of the pneumatic cylinder 6, and a plurality of supporting components installed outside the rotating block 7. The supporting component includes a supporting leg 8 installed on the outside of the rotating block 7 and having an L-shaped structure, and a base plate 9 installed at the bottom of the supporting leg 8. No matter how the two supporting components move, under the action of the moving mechanism, the two supporting components are symmetrically arranged with each other, and the weight shared by the two pneumatic cylinders 6 can be made consistent. A plurality of wheels are arranged at the bottom of the trailer body 1.

[0022] It should be noted that when this lightweight trailer with pneumatic legs is in use and the road surface is flat, the rotating motor 15 can be started, and the rotating motor 15 will drive the first bevel gear 13 to rotate. Under the engagement of the first bevel gear 13 and the second bevel gear 14, the threaded rod 16 will rotate. When the threaded rod 16 rotates, it will drive the movable plate 4 to move. Driven by the movable plate 4, the pneumatic cylinder 6 will move, thereby driving the support assembly to move. When it moves to a position where the road surface is flat, the rotating motor 15 stops working, and the pneumatic cylinder 6 will drive the support assembly to move downward. When the road surface corresponding to the support assembly is still uneven, the rotating block 7 can be rotated, and the multiple support legs 8 will rotate, so that the position of the multiple base plates 9 can be adjusted to a suitable position.

[0023] Example 2

[0024] like Figure 1 - Figure 5 The figure shows a lightweight trailer with pneumatic legs, wherein the sliding mechanism includes a T-shaped slide groove 5 opened at the bottom of a connecting frame 2, a T-shaped slider 11 slidably connected to the inside of the T-shaped slide groove 5, and a hydraulic cylinder 12 installed on the inner wall of one side of the T-shaped slide groove 5, wherein the output end of the hydraulic cylinder 12 is fixedly connected to one side of the T-shaped slider 11.

[0025] It should be noted that this lightweight trailer with pneumatic legs can flexibly adjust the position of the support assembly according to the change of the center of gravity of the semi-trailer when in use. When the position of the support assembly needs to be adjusted, the hydraulic cylinder 12 will drive the T-shaped slider 11 to move, and the fixed cylinder 3 will move under the drive of the T-shaped slider 11, so that the front and rear position of the support assembly can be adjusted to make the car body more stable.

[0026] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
