Description

Technical Field

[0001] The utility model relates to the technical field of trailer protection, in particular to a trailer anti-rollover device. Background Art

[0002] A trailer is a vehicle that is towed by a car and has no power drive device. It is a combination of a car and one or more trailers. The truck and the tractor are the driving sections of the car train, which are called the main car. The driven section towed by the main car is called a trailer, which is an important type of road transportation. The use of car train transportation is the most effective and simple important means to improve economic efficiency. It has the advantages of rapidity, mobility, flexibility, and safety; it can easily realize section transportation. A trailer can only form a complete means of transportation together with a tractor or other cars. The total weight of the trailer is borne by itself, which is called a full trailer, and is usually referred to as a trailer. The characteristics are that it has no power, carries independently, and relies on other vehicles to travel. The trailer is a non-powered road vehicle that needs to be towed by a car for normal use due to its design and technical characteristics. It is used to carry people or goods for special purposes.

[0003] The Chinese patent with the publication number CN215851157U discloses a trailer anti-rollover device, which includes a trailer body, and a plurality of supporting devices are arranged at the bottom of the trailer body, and the supporting devices include a fixed block fixed to the bottom of the trailer body, and an electric push rod is fixed to the inner top of the fixed block, and a slide plate is fixed at the rod head of the electric push rod, and the bottom of the slide plate is connected to the inner bottom of the fixed block through a supporting spring, and a connecting column is fixed to the bottom of the slide plate, and the bottom of the connecting column passes through the bottom of the fixed block and is fixed with a support plate, and a plurality of adjusting devices and limiting devices are arranged inside the support plate. In this device, by arranging the adjusting device, the support mode of the support plate can be adjusted, so that the columnar block with a conical bottom can be inserted into the inside of the softer ground, and the stability of the support plate can be ensured, so that the anti-rollover device of the trailer can be more widely applicable and the trailer can be safer.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] The existing device can adjust the supporting mode of the support plate by setting an adjustment device, so that the cylindrical block with a cone-shaped bottom can be inserted into the softer ground, which can ensure the stability of the support plate. However, the existing device can only prevent the trailer from tipping when it stops unloading. In the process of trailer transportation, special situations such as sharp turns may be encountered. The trailer may tilt the cargo to one side during turning, causing the trailer to lose balance and roll over, which will cause danger and economic losses. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a trailer anti-rollover device, wherein the device is connected with a damper at the bottom of the vehicle body through multiple connecting blocks, the damper is provided with a first spring, the other end of the damper is connected with a mounting block, the first roller can roll on the mounting block through a rotating rod, a bottom plate is installed inside the vehicle body, the goods to be transported are placed on the bottom plate, a partition is installed on the bottom plate, and the goods are placed separately, when the trailer is tilted, the carried goods can be blocked by the partition and will not all fall to one side and cause overturning, the damper at the bottom of the vehicle body can play a damping role when tilting to prevent the vehicle body from overturning, under normal circumstances, a pair of second springs at the bottom of the slide box support the slide box, in special circumstances, the tilt angle of the vehicle body is too large, The ball inside the slide box rolls from the middle slot to the slot on the inclined side. The increased weight at this end of the slide box is driven to move downward, and the resistance rod fixedly installed at the bottom of the slide box resists the sensing button, which transmits the signal to the water pump. Under normal circumstances, the water counterweight inside a pair of counterweight water tanks is the same. When receiving the sensing button signal on the inclined side, the water pump works to pump the water in the counterweight water tank on the inclined side to the counterweight water tank on the other side, so that the increased weight on the other side offsets the force on the inclined side, thereby preventing the trailer from tipping over. At the same time, the sensing button transmits the signal to the electric telescopic rod on the inclined side, and the electric telescopic rod on the inclined side extends outward, so that the second roller at one end of the electric telescopic rod contacts the ground for support, which can effectively prevent the trailer from tipping over.

[0011] In some embodiments, a pair of mounting plates are fixedly installed at the bottom of the vehicle body, and an electric telescopic rod is fixedly connected to the pair of mounting plates. The pair of electric telescopic rods are electrically connected to a pair of sensing buttons, and the pair of electric telescopic rods are slidably connected to the vehicle body, and the other ends of the pair of electric telescopic rods are rotatably connected to a second roller.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] First, the utility model aims at the existing device, which has special situations such as sharp turns during the trailer transportation process.

When the trailer tilts, the cargo can be blocked by the partition and will not fall to one side and cause rollover. The damper at the bottom of the car body can play a damping role when it tilts to prevent the car body from tipping over. Under normal circumstances, a pair of first The second spring supports the slide box. In special circumstances, the tilt angle of the car body is too large, and the ball inside the slide box rolls from the middle slot hole to the slot hole on the tilted side. The increased weight at this end of the slide box is driven to move downward, and the resistance rod fixedly installed at the bottom of the slide box resists the sensing button, and the sensing button transmits the signal to the water pump. Under normal circumstances, the water counterweight inside a pair of counterweight water tanks is the same. When receiving the sensing button signal on the tilted side, the water pump works to pump the water in the counterweight water tank on the tilted side to the counterweight water tank on the other side, so that the increased weight on the other side offsets the force on the tilted side, thereby playing an anti-rollover effect. At the same time, the sensing button transmits the signal to the electric telescopic rod on the tilted side, and the electric telescopic rod on the tilted side extends outward, so that the second roller at one end of the electric telescopic rod contacts the ground to play a supporting role, which can effectively prevent the trailer from tipping over.
