Description
Technical Field
[0001] The present application relates to the technical field of semi-trailers, and in particular to a box-type semi-trailer. Background Art
[0002] A van semi-trailer is a semi-trailer that can transport a lot of goods at one time. It includes a front, a rear trailer frame, and a compartment mounted on the rear trailer frame. Since a van semi-trailer can transport a lot of goods at one time, it is usually used as a tool for long-distance transportation. In order to meet the long-distance travel requirements of a van semi-trailer, the fuel tank of a van semi-trailer is also larger.
[0003] In the related art, the fuel tank of a van-type semi-trailer is arranged outside the side of the rear trailer frame. When the semi-trailer driver is sleeping at night, some oil thieves will directly open the fuel tank cover of the semi-trailer and insert a pipe into the fuel tank to steal the oil, thereby making the anti-theft performance of the semi-trailer fuel tank poor and the oil in the fuel tank is easy to be stolen. Utility Model Content
[0004] In order to prevent the oil in the oil tank of a semi-trailer from being stolen, the present application provides a box-type semi-trailer.
[0005] The present application provides a box-type semi-trailer, which adopts the following technical solution:
[0006] A box-type semi-trailer comprises a vehicle body and a fuel tank, wherein the fuel tank is mounted on one side of the vehicle body and is provided with a partition plate inside the fuel tank, wherein an oil storage chamber and an oil-free chamber for inserting a fuel gun are formed inside the fuel tank through the partition plate, and a one-way valve is provided on the partition plate to allow the oil in the fuel gun to enter the oil storage chamber.
[0007] In order to allow the oil in the refueling gun to accurately enter the oil storage chamber through the one-way valve, a guide pipe for inserting the refueling gun is provided on the outer wall of the oil tank. The guide pipe extends into the oil-free chamber and is connected to the one-way valve.
[0008] In order to enable the oil to have a greater impact force to open the one-way valve, the diameter of the oil inlet of the one-way valve is smaller than the inner diameter of the guide pipe.
[0009] An adapter is provided at one end of the guide pipe close to the one-way valve, a adapter tube is sleeved on the adapter, an end of the adapter tube away from the adapter is connected to the oil inlet of the one-way valve, and the inner diameter of the adapter tube is smaller than the inner diameter of the guide pipe.
[0010] In order to enable the oil level to be higher than the position of the one-way valve and thereby increase the volume of oil contained in the oil tank as much as possible, the oil outlet of the one-way valve is located in the oil storage chamber, and a hard flow guide tube is installed at the oil outlet of the one-way valve, and the end of the hard flow guide tube away from the one-way valve extends toward the top of the oil storage chamber.
[0011] In order to facilitate the installation of the oil tank, a U-shaped load-bearing frame is welded on the outer side wall of one side of the vehicle body, and the oil tank is installed on the U-shaped load-bearing frame.
[0012] In order to protect the fuel tank and relieve the impact force after the fuel tank is hit, the side of the U-shaped load-bearing frame facing away from the vehicle body protrudes from the fuel tank.
[0013] A crash barrier is arranged on a side of the U-shaped carrier away from the vehicle body.
[0014] In summary, the present application includes at least one of the following beneficial technical effects:
[0015] The oil tank is formed with an oil storage chamber and an oil-free chamber by a partition. When refueling, oil can enter the oil storage chamber under the action of a one-way valve, but the oil in the oil storage chamber is not easy to enter the oil-free chamber. The oil thief can only insert the oil stealing pipe into the guide pipe, and it is not easy to extract the oil in the oil storage chamber, so that the oil in the oil tank is not easy to be stolen.
[0016] The inner diameter of the transfer tube is smaller than that of the guide tube, so even if a thief inserts the oil-stealing tube into the guide tube, it is not easy for the oil-stealing tube to enter the transfer tube, further improving the safety of the fuel tank;
[0017] The side of the U-shaped carrier frame facing away from the vehicle body not only protrudes from the fuel tank but is also provided with an anti-collision guardrail. When the fuel tank is hit, the anti-collision guardrail and the U-shaped carrier frame will protect the fuel tank. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0023] The following is combined with Figure 1-4 This application is described in further detail.
[0024] The present application embodiment discloses a box-type semi-trailer. Figure 1 and Figure 2 The van semi-trailer includes a vehicle body 1 and a fuel tank 2. A partition 21 is provided in the fuel tank 2. The fuel tank 2 forms an oil storage chamber 22 and an oil-free chamber 23 through the partition 21. When refueling the fuel tank 2, the refueling gun can be inserted into the oil-free chamber 23 and then enter the oil storage chamber 22 for storage. When a thief steals oil, the oil-stealing pipe can only be inserted into the oil-free chamber 23 and it is not easy to extract the oil in the oil storage chamber 22, thereby improving the safety of the fuel tank 2.
[0025] The vehicle body 1 includes a tractor head 11, a rear trailer frame 12, and a carriage 13 installed on the top of the rear trailer frame 12. The rear trailer frame 12 is installed at the rear of the tractor body 1, and the rear trailer frame 12 is moved by the tractor body 1, and the carriage 13 is used to place the transported goods. The fuel tank 2 is installed on the outer wall of one side of the rear trailer frame 12.
[0026] Reference Figure 1 and Figure 3 A U-shaped load-bearing frame 14 is welded on the outer wall of one side of the rear trailer frame 12, and the opening of the U-shaped load-bearing frame 14 faces upward. The fuel tank 2 is fixed to the inside of the U-shaped load-bearing frame 14 by fasteners, so that the fuel tank 2 can be protected. Among them, the side of the U-shaped load-bearing frame 14 away from the rear trailer frame 12 protrudes from the fuel tank 2, and the side of the U-shaped load-bearing frame 14 away from the rear trailer frame 12 is welded with an anti-collision guardrail 15, that is, there is a certain gap between the anti-collision guardrail 15 and the outer wall of the fuel tank 2. When the fuel tank 2 is hit, the anti-collision guardrail 15 will bear part of the impact force and transfer the impact force to the rear trailer frame 12 with greater strength through the U-shaped load-bearing frame 14, thereby protecting the fuel tank 2.
[0027] Reference Figure 2 and Figure 4, a one-way valve 24 is arranged on the partition 21, and the oil inlet of the one-way valve 24 is located in the oil-free chamber 23; the oil outlet of the one-way valve 24 is located in the oil storage chamber 22, and the oil in the oil storage chamber 22 can enter the oil-free chamber 23 through the one-way valve 24, and the oil in the oil storage chamber 22 is not easy to enter the oil-free chamber 23 through the one-way valve 24. In addition, since the refueling gun refuels the oil storage chamber 22 through the oil-free chamber 23, and the oil in the oil storage chamber 22 is not easy to enter the oil-free chamber 23, the automatic stop device inside the refueling gun cannot work, so a liquid level line and an observation port are arranged on the side wall of the oil storage chamber 22, and the staff of the gas station can observe the height of the liquid level in the oil storage chamber 22 through the observation port to control the refueling amount.
[0028] Reference Figure 2 and Figure 4 A guide pipe 25 is fixedly mounted on the outer wall of the oil tank 2. The guide pipe 25 is located within the oil-free chamber 23 and extends to the inside of the oil-free chamber 23. The tip of the refueling gun can be inserted into the guide pipe 25 to inject oil into the oil storage chamber 22 through the one-way valve 24. One end of the guide pipe 25 away from the oil-free chamber 23 is exposed to the outside of the oil tank 2 and is covered with an oil tank 2 cover.
[0029] The diameter of the oil inlet of the one-way valve 24 is smaller than the inner diameter of the guide pipe 25, so an adapter 26 is installed at one end of the guide pipe 25 close to the one-way valve 24, and one end of the adapter 26 is sleeved and threadedly installed on the guide pipe 25; the other end is connected to a transfer tube 27, and the end of the transfer tube 27 away from the adapter 26 is sleeved on the one-way valve 24 and communicates with the oil inlet of the one-way valve 24. Among them, the inner diameter of the transfer tube 27 is smaller than the inner diameter of the guide pipe 25, so that the impact force of the oil entering the transfer tube 27 from the guide pipe 25 will be larger, which can more easily open the valve plate inside the one-way valve 24, and then the oil can enter the oil storage chamber 22 more smoothly through the one-way valve 24. In addition, since the inner diameter of the transfer tube 27 is smaller than the inner diameter of the guide pipe 25, and the oil pipe of the thief is generally a pipe with the same outer diameter, it is not easy for the thief to insert the oil pipe into the transfer tube 27, which further improves the anti-theft performance of the oil tank 2.
[0030] Reference Figure 2 and Figure 4 A hard guide tube 28 is sleeved at the oil outlet of the one-way valve 24. The end of the hard guide tube 28 that is away from the oil outlet of the one-way valve 24 extends upward in the vertical direction. The hard guide tube 28 is made of hard material and is not easy to deform. Even when the liquid level in the oil storage chamber 22 exceeds the one-way valve 24, the oil can smoothly enter the oil storage chamber 22 through the hard guide tube 28, and is not easily affected by the water pressure in the oil storage chamber 22, so that the oil storage chamber 22 can store the maximum amount of oil.
[0031] The implementation principle of a van-type semi-trailer in the embodiment of the present application is as follows: the oil tank 2 forms an oil storage chamber 22 and an oil-free chamber 23 through a partition 21, and the oil can enter the oil storage chamber 22 when refueling under the action of a one-way valve 24. When refueling, the gun head of the refueling gun is inserted into the guide pipe 25, and the oil enters the oil storage chamber 22 after passing through the transfer pipe 27 and the one-way valve 24. Since the inner diameter of the transfer pipe 27 is smaller than the inner diameter of the guide pipe 25, if an oil thief wants to steal oil, he can only insert the oil stealing pipe into the guide pipe 25, and it is not easy to extract the oil in the oil storage chamber 22, thereby making it difficult for the oil in the oil tank 2 to be stolen.
[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
