Description

Technical Field

[0001] This utility model relates to the field of large vehicle rescue technology, specifically, it is a brake system connecting pipe for large vehicle rescue. Background Technology

[0002] With the development of the times, there are more and more vehicles traveling on highways. The longer a vehicle stays on the highway, the higher the risk of an accident. In the process of highway rescue, effectively shortening the rescue time can reduce the probability of accidents to a greater extent.

[0003] Furthermore, ensuring the braking stability of the large vehicle being rescued during downhill descent is crucial for a safe rescue. Connecting the pneumatic braking system of the following vehicle to the rescue vehicle requires a brake connection pipe. However, due to the variety of vehicles being rescued, the interfaces of the brake connection pipes differ. Consequently, because the brake connection pipes are very long, numerous pipes with different interfaces become tangled and difficult to separate during storage and retrieval, and also occupy a significant amount of space for storage. Utility Model Content

[0004] The purpose of this utility model is to provide a brake system connecting pipe for large vehicle rescue, so as to solve the problem that the existing brake system connecting pipes need to be replaced as a whole when rescuing different vehicles.

[0005] To solve the above problems, the present invention adopts the following technical means:

[0006] A brake system connecting pipe for large vehicle rescue includes a first air pipe connected to the pneumatic brake system of the rescue vehicle and a second air pipe connected to the pneumatic brake system of the vehicle being rescued, wherein the first air pipe and the second air pipe are connected by a connecting mechanism.

[0007] The connecting mechanism includes an air outlet pipe coaxially connected to the air outlet end of the first air pipe and a connecting mechanism detachably connected to the end of the air outlet pipe opposite to the first air pipe. The connecting mechanism is connected to the second air pipe.

[0008] The connecting mechanism includes a connecting pipe with one end extending into the air outlet pipe, a connecting tube rotatably mounted on the side wall of the end of the connecting pipe extending out of the air outlet pipe, the inner wall of the connecting tube being threadedly connected to the outer wall of the air outlet pipe, the outer wall of the connecting tube being connected to the connecting tube via a sliding limiting mechanism, and a gas supply pipe coaxially rotatably connected to the end of the connecting tube opposite to the air outlet pipe, the gas supply pipe being connected to the second air pipe, and the gas supply pipe being connected to the connecting pipe;

[0009] The inner cavity of the outlet pipe is required to be constructed as an airflow cavity and a receiving cavity along the airflow direction. The inner diameter of the receiving cavity is the same as the outer diameter of the connecting pipe, and the inner diameter of the airflow cavity is the same as the inner diameter of the connecting pipe. The connection part of the airflow cavity and the receiving cavity forms a first step that abuts against the end of the connecting pipe.

[0010] Preferably, the sliding limiting mechanism includes an annular groove coaxially disposed on the inner wall of the connecting pipe and a limiting ring coaxially disposed on the outer wall of the connecting pipe. The limiting ring is slidably disposed in the annular groove, and the length of the annular groove along the axial direction is greater than the length of the limiting ring along the axial direction.

[0011] Furthermore, the inner diameter of the connecting pipe is the same as the inner diameter of the gas supply pipe, the inner diameter of the gas supply pipe is smaller than the inner diameter of the connecting pipe, and the connection position of the gas supply pipe and the connecting pipe forms a second step. In use, both ends of the connecting pipe abut against the first step and the second step respectively, and the limiting ring is located in the middle of the annular groove.

[0012] Furthermore, a first sealing ring is coaxially installed on the first step, and a second sealing ring is coaxially installed on the second step.

[0013] This utility model has the following beneficial effects during use:

[0014] For the overall connecting pipe system, the end of the first air pipe is equipped with a connector that matches the pneumatic braking system of the rescue vehicle, while the end of the second air pipe is equipped with a structure that matches the pneumatic braking system of the vehicle being rescued. By setting multiple second air pipes with different connectors, the second air pipes are connected to the first air pipes through a connecting mechanism, enabling the overall connecting pipe system to rescue different vehicles. The length of the second air pipe can be set very short, so that the first air pipe can always be installed on the rescue vehicle. After determining the location of the vehicle being rescued, the second air pipe with the corresponding connector is selected according to actual needs, and the second air pipe is connected to the first air pipe to perform the rescue. This allows the braking system of the rescue vehicle to be shared with the braking system of the vehicle being rescued. Moreover, when connecting the second and first air pipes, a connecting pipe is inserted into the outlet air pipe, and the connecting pipe is threaded into the outlet air pipe, allowing the connecting pipe to abut against the first step to complete the assembly. With the connecting pipe abutting against the first step, the airtightness of the entire connecting mechanism is also improved. Attached Figure Description

[0025] Please refer to Figures 1 to 3 As shown, a brake system connecting pipe for large vehicle rescue includes a first air pipe 1 connected to the pneumatic brake system of the rescue vehicle and a second air pipe 2 connected to the pneumatic brake system of the vehicle being rescued. The first air pipe 1 and the second air pipe 2 are connected by a connecting mechanism.

[0026] The connecting mechanism includes an air outlet pipe 3 coaxially connected to the air outlet end of the first air pipe 1 and a connecting mechanism detachably connected to the end of the air outlet pipe 3 facing away from the first air pipe 1. The connecting mechanism is connected to the second air pipe 2.

[0027] The connecting mechanism includes a connecting pipe 4 with one end extending into the air outlet pipe 3. A connecting pipe 5 is rotatably installed on the side wall of the end of the connecting pipe 4 extending out of the air outlet pipe 3. The inner wall of the connecting pipe 5 is threadedly connected to the outer wall of the air outlet pipe 3. The outer wall of the connecting pipe 4 is connected to the connecting pipe 5 through a sliding limiting mechanism. A gas supply pipe 6 is coaxially rotatably connected to the end of the connecting pipe 5 opposite to the air outlet pipe 3. The gas supply pipe 6 is connected to the second air pipe 2 and the connecting pipe 4.

[0028] The inner cavity of the air outlet pipe 3 is required to be constructed as an airflow cavity 7 and a receiving cavity 8 along the airflow direction. The inner diameter of the receiving cavity 8 is the same as the outer diameter of the connecting pipe 4, and the inner diameter of the airflow cavity 7 is the same as the inner diameter of the connecting pipe 4. The connection part of the airflow cavity 7 and the receiving cavity 8 forms a first step 9 that abuts against the end of the connecting pipe 4.

[0029] In this way, for the overall connecting pipe, the end of the first air pipe 1 is equipped with a connector that matches the pneumatic braking system of the rescue vehicle, while the end of the second air pipe 2 is equipped with a structure that matches the pneumatic braking system of the vehicle being rescued. By setting multiple second air pipes 2 with different connectors, and connecting the second air pipes 2 and the first air pipe 1 through a connecting mechanism, the overall connecting pipe can be used to rescue different vehicles. The length of the second air pipe 2 can be set very short, so that the first air pipe 1 can always be installed on the rescue vehicle. After determining the location of the vehicle being rescued, the second air pipe 2 with the corresponding connector is selected according to actual needs, and the second air pipe 2 is connected to the first air pipe 1 to carry out the rescue. This allows the braking system of the rescue vehicle to be shared with the braking system of the vehicle being rescued. Furthermore, when connecting the second air pipe 2 and the first air pipe 1, the connecting pipe 4 is inserted into the air outlet pipe 3, and the connecting pipe 5 is threadedly connected to the air outlet pipe 3, so that the connecting pipe 4 abuts against the first step 9, thereby completing the assembly. In the state where the connecting pipe 4 abuts against the first step 9, the airtightness of the entire connecting mechanism can also be improved.

[0030] Specifically, the sliding limiting mechanism includes an annular groove 10 coaxially disposed on the inner wall of the connecting pipe 5 and a limiting ring 11 coaxially disposed on the outer wall of the connecting pipe 4. The limiting ring 11 is slidably disposed in the annular groove 10, and the length of the annular groove 10 along the axial direction is greater than the length of the limiting ring 11 along the axial direction.

[0031] Furthermore, the inner diameter of the connecting pipe 4 is the same as the inner diameter of the gas supply pipe 6, the inner diameter of the gas supply pipe 6 is smaller than the inner diameter of the connecting pipe 5, and the connection position of the gas supply pipe 6 and the connecting pipe 5 forms a second step 12. In use, both ends of the connecting pipe 4 abut against the first step 9 and the second step 12 respectively, and the limiting ring 11 is located in the middle of the annular groove 10.

[0032] To ensure the airtightness of the entire connecting mechanism, a first sealing ring 13 is coaxially installed on the first step 9, and a second sealing ring 14 is coaxially installed on the second step 12.

[0033] Thus, with the connecting pipe 5 and the air outlet pipe 3 connected by threads, as the threads are inserted, both ends of the connecting pipe 4 continuously abut against the first step 9 and the second step 12. This, combined with the action of the first sealing ring 13 and the second sealing ring 14, ensures the entire connecting mechanism has good airtightness, thereby guaranteeing the normal operation of the braking system. Therefore, the threaded connection between the connecting pipe 5 and the air outlet pipe 3 not only improves installation convenience but also increases the abutting force on both ends of the connecting pipe 4.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
