Description

Technical Field

[0001] The invention relates to the technical field of tire repair equipment, and in particular to a tire repair device for a container truck. Background Art

[0002] When a container truck is loaded with lighter cargo (such as 1 to 5 tons), its tire pressure can be relatively low, but generally should be above 5 bar to maintain the stability and handling of the vehicle. For steel tires, due to their higher structural strength, the tire pressure can be appropriately increased to about 6 bar.

[0003] As the load increases, the tires need to withstand greater pressure. Therefore, for container trucks carrying 10 to 15 tons of cargo, the tire pressure usually needs to be increased to around 10 bar; while for vehicles carrying 15 to 20 tons or more of cargo, the tire pressure should be between 12 and 13 bar.

[0004] But in any case, the air pressure should not exceed the maximum safety pressure value specified by the tire manufacturer, which is generally around 14 bar.

[0005] Generally speaking, the pressure range of truck gas tanks (including those used in container trucks) is around 8~12 bar. This range is determined based on the conventional design and safe use requirements of gas tanks, and is intended to ensure the normal operation of the braking system and other related systems.

[0006] When the tire pressure is low, the truck needs to drive to a tire repair station or call a mobile tire repair vehicle to use its high-power air compressor to provide air to inflate the tire. However, if an emergency occurs or the tire needs to be inflated during driving, the emergency air pump is difficult to reach the pressure requirement. Summary of the invention

[0007] In order to solve the above problems, the purpose of the present invention is to provide a tire repair device for a container truck, which can be connected to the brake air tank of the container truck to inflate the tire, and can meet the tire pressure requirements to ensure the normal driving of the truck. It is suitable for trucks with a load capacity of less than 15 tons; in addition, the device can be connected to a tire repair fluid bottle to repair the tire, which is very convenient.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: A tire repair device for a container truck, comprising a device body, characterized in that: the device body comprises a shell, and a pipeline assembly arranged in the shell; an air inlet nozzle for connecting to an air storage tank through a pipeline and an air outlet pipe for connecting to a tire repair liquid tank or a tire are extended out of the shell; the pipeline assembly is connected to the air inlet nozzle and the air outlet pipe; The pipeline assembly at least includes an air-infusing pipeline and a tire-repairing pipeline arranged in parallel, and a gear assembly arranged at the front connection of the air-infusing pipeline and the tire-repairing pipeline; a pressure relief valve for limiting the ventilation pressure range inside the tire-repairing pipeline is arranged on the tire-repairing pipeline, and the gear assembly is used to control the opening and closing of the air-infusing pipeline and the tire-repairing pipeline with the main pipeline; In the off mode: the air supply pipeline and tire repair pipeline controlled by the gear assembly are disconnected from the main pipeline; In inflation mode: the gear assembly controls only the air supply line to be connected to the main line, and the air outlet pipe is connected to the tire; In tire repair mode: the gear assembly controls only the tire repair pipeline to be connected to the main pipeline, and the air outlet pipe is connected to the air inlet end of the tire repair liquid tank.

[0009] In the above technical solution, the air inlet nozzle of the tire repair device for container trucks is connected to the brake air tank: ① When the tire needs to be inflated, connect the outlet pipe to the tire valve core, select the inflation mode for the gear assembly, connect the air supply line to the main line, and the air flow in the air tank passes through the air inlet nozzle, the main line, the air supply line, and the outlet pipe to the tire for inflation. When the tire reaches the specified pressure, the gear assembly selects the closed mode; ②When the tire needs to be repaired, connect the air outlet pipe to the air inlet of the tire repair liquid bottle, and connect the liquid outlet pipe of the tire repair liquid bottle to the tire valve core. The gear assembly selects the tire repair mode, the tire repair pipeline is connected to the main pipeline, and the air in the air tank passes through the air inlet, main pipeline, tire repair pipeline, air outlet pipe, tire repair liquid bottle to the tire for repair, and the tire repair liquid is filled into the tire. When repairing the tire, the pressure rises to the maximum pressure, and then the pressure in the tire repair pipeline is maintained within a certain range through the pressure relief valve to prevent the high air output flow of the air tank from causing the tire repair liquid to break and block the valve core. After the tire is repaired, if the pressure drops, the gear assembly can select the inflation mode in ①. After the tire reaches the specified pressure, the gear assembly selects the closed mode.

[0010] Therefore, the tires can be inflated through the container truck's own brake air tank combined with this device to meet the tire pressure requirements of large vehicles. At the same time, emergency repairs can be performed on damaged tires, so there is no need to call for rescue, which can save a lot of time and cost and avoid unnecessary trouble.

[0011] Preferably, the shift assembly includes a shift switch and a three-way valve connected to the bottom of the shift switch. The main pipeline of the pipeline assembly includes an air intake pipeline connected between the air inlet nozzle and the three-way valve. The inlet ends of the air supply pipeline and the tire repair pipeline are connected to the three-way valve. The shift switch can connect the air intake pipeline and the air supply pipeline in the air supply mode, connect the air intake pipeline and the tire repair pipeline in the tire repair mode, and close the air intake pipeline in the closed mode. In this technical solution, the shift switch can be switched between closed, inflated and tire repair. The three-way valve is used to connect the air intake pipeline, the air supply pipeline and the tire repair pipeline. By switching the position of the valve, the outlet of the air intake pipeline can be cut off, or the airflow direction can be changed, so that the airflow can be selected to be input into the air supply pipeline or the tire repair pipeline, which is very flexible.

[0012] Preferably, the air inlet pipeline is connected to the air inlet nozzle via a connecting seat. In this technical solution, the connecting seat plays a role in stabilizing the air inlet nozzle and the air inlet pipeline.

In this technical solution, the multi-way valve can be arranged to facilitate the connection of the ends of the air supply pipeline and the tire repair pipeline, as well as the inlet of the air outlet pipe, so as to facilitate the distribution of airflow.

[0015] Preferably, the multi-way valve is also connected to a deflation pipeline, a deflation valve is provided at the end of the deflation pipeline, the upper end of the pressing knob of the deflation valve is flush with the end surface of the shell, and a pressing groove is provided on the outer side of the pressing knob.

[0027] like Figures 1 to 5 A tire repair device for a container truck shown in the figure comprises a device body, the device body comprises a shell 1, and a pipeline assembly arranged in the shell 1; an air inlet nozzle 2 for connecting to an air storage tank through a pipeline and an air outlet pipe 3 for connecting to a tire repair liquid tank or a tire are extended out of the shell 1; the pipeline assembly is connected with the air inlet nozzle 2 and the air outlet pipe 3; The pipeline assembly at least includes an air supply pipeline 4 and a tire repair pipeline 5 arranged in parallel, and a gear assembly 6 arranged at the front connection of the air supply pipeline 4 and the tire repair pipeline 5; the tire repair pipeline 5 is provided with a pressure relief valve 7 for limiting the ventilation pressure range inside the tire repair pipeline 5, and the gear assembly 6 is used to control the connection and disconnection of the air supply pipeline 4 and the tire repair pipeline 5 with the main pipeline; In the closed mode: the gear assembly 6 controls the air supply pipeline 4 and the tire repair pipeline 5 to be disconnected from the main pipeline; In the inflation mode: the gear assembly 6 controls only the air supply line 4 to be connected to the main line, and the air outlet pipe 3 is connected to the tire; In the tire repair mode: the gear assembly 6 controls only the tire repair pipeline 5 to be connected to the main pipeline, and the air outlet pipe 3 is connected to the air inlet end of the tire repair liquid tank.

[0028] In the above technical solution, the air inlet nozzle of the tire repair device for container trucks is connected to the brake air tank: ① When the tire needs to be inflated, connect the outlet pipe to the tire valve core, select the inflation mode for the gear assembly, connect the air supply line to the main line, and the air flow in the air tank passes through the air inlet nozzle, the main line, the air supply line, and the outlet pipe to the tire for inflation.

[0030] Therefore, the tires can be inflated and repaired by combining the brake air tank of the container truck itself with the device, which can meet the tire pressure requirements of large vehicles and solve the problems of air leakage and tire damage during driving of the vehicle, which is very convenient.

[0031] Furthermore, the shift assembly 6 includes a shift switch 8 and a three-way valve 9 connected to the bottom of the shift switch 8. The main pipeline of the pipeline assembly includes an air intake pipeline 10 connected between the air intake nozzle 2 and the three-way valve 9.

The shift switch 8 can connect the air intake pipeline 10 and the air supply pipeline 4 in the air supply mode, connect the air intake pipeline 10 and the tire repair pipeline 5 in the tire repair mode, and close the air intake pipeline 10 in the closed mode. In this technical solution, the shift switch can be switched between closed, inflated and tire repair. The three-way valve is used to connect the air intake pipeline, the air supply pipeline and the tire repair pipeline. By switching the position of the valve, the outlet of the air intake pipeline can be cut off, or the airflow direction can be changed, so that the airflow can be selected to be input into the air supply pipeline or the tire repair pipeline, which is very flexible.

[0037] In this specific embodiment, in view of the problem that the existing container truck tires are leaking and need to be inflated in a special place, and in emergencies and during the driving of the car, the existing emergency air pump cannot adapt to the tire pressure, the above solution can inflate and repair the tires through the truck's own brake air tank combined with the container truck tire repair device in this case.

When repairing the tire, the pressure rises to the maximum pressure, and then the pressure in the tire repair pipeline is maintained within a certain range through the pressure relief valve to prevent the high air output flow of the air storage tank from causing the tire sealant to break the emulsion and block the valve core. Observe the pressure gauge. After the tire is repaired, if the pressure drops, the gear component can select the inflation mode in ①. After the tire reaches the specified pressure, the gear component selects the closing mode.

[0039] Therefore, the tires can be inflated through the container truck's own brake air tank combined with this device to meet the tire pressure requirements of large vehicles.
