Technical Field

[0001] This utility model relates to the field of mining machinery, and in particular to a pressure detection device and an off-highway dump truck having the pressure detection device. Background Technology

[0002] During the operation of mining dump trucks, malfunctions such as insufficient air pressure in the braking system, insufficient braking force, and brake failure may occur. To quickly diagnose and resolve these issues, an air pressure testing device is needed to inspect the vehicle's braking system air circuit. Existing air pressure testing devices are all designed for highway vehicles, and their connectors and pipes are often incompatible with off-highway dump trucks. Therefore, a new air pressure testing device compatible with off-highway mining dump trucks needs to be designed. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a pressure detection device and an off-highway dump truck that can be adapted to off-highway mining dump trucks, and can also quickly troubleshoot and avoid safety problems.

[0004] One embodiment of this utility model provides an air pressure detection device for detecting the air pressure of the braking system of an off-highway dump truck. The air pressure detection device includes a pressure gauge for measuring air pressure and a connector for connecting the pressure gauge to the braking system of the off-highway dump truck to detect the air pressure in the braking system through the pressure gauge.

[0005] Furthermore, there is one pressure gauge and multiple connectors. These connectors are used to selectively connect multiple brake chambers in the braking system to the pressure gauge, allowing for selective detection of air pressure in the multiple brake chambers. Furthermore, the taillight bracket side plate has a connecting plate at the end near the taillight bracket support for connecting to the taillight bracket top plate.

[0006] Furthermore, there are multiple pressure gauges and connectors, with each connector corresponding to a pressure gauge. Each connector is used to connect a brake chamber in the braking system to the corresponding pressure gauge so that the air pressure in the brake chamber can be detected by the pressure gauge.

[0007] Furthermore, it also includes a first conduit for connecting the pressure gauge to the connector and a second conduit for connecting the connector to the brake chamber.

[0008] Furthermore, the second conduit includes a parking chamber conduit for connecting the connector to the parking chamber of the brake chamber and a driving chamber conduit for connecting the connector to the driving chamber of the brake chamber.

[0009] Furthermore, the connector selectively connects the parking chamber pipe and the driving chamber pipe to the first pipe.

[0010] An off-highway dump truck includes a braking system and the aforementioned air pressure detection device, wherein the pressure gauge of the air pressure detection device is used to detect the air pressure in the braking system.

[0011] Furthermore, the braking system includes multiple brake chambers, and the number of connectors of the air pressure detection device is multiple and corresponds to the multiple brake chambers. The multiple brake chambers are respectively connected to pressure gauges through multiple connectors to detect the air pressure in the brake chambers through the pressure gauges.

[0012] Furthermore, each brake chamber includes a parking chamber and a driving chamber, and each connector selectively connects the parking chamber and driving chamber of the corresponding brake chamber to a pressure gauge to selectively detect the air pressure in the parking chamber or driving chamber.

[0013] Furthermore, multiple connectors are used to selectively connect multiple brake chambers to pressure gauges, so as to selectively detect the air pressure in multiple brake chambers by means of pressure gauges; when the pressure gauge detects the air pressure in any one of the multiple brake chambers, the connectors corresponding to the other brake chambers in the multiple brake chambers are closed to block the corresponding brake chambers.

[0014] This utility model provides a pressure testing device, including a pressure gauge, a connector, a first pipe, and a second pipe. The pressure gauge is connected to the connector via the first pipe, and the connector is connected to the brake chamber via the second pipe. Multiple connectors are available, allowing selection of the appropriate connector based on the brake chamber's interface. This ensures compatibility with off-highway dump trucks and improves the reliability of the pressure testing results. The second pipe includes a parking chamber pipe and a driving chamber pipe, respectively connected to two different chambers of the brake chamber. This allows the pressure gauge to selectively test the pressure in different chambers, enabling rapid identification of vehicle malfunctions based on the pressure readings and preventing safety issues such as reduced braking performance due to insufficient air pressure during vehicle operation.

[0020] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0021] like Figures 1 to 3 As shown, one embodiment of the present invention provides an off-highway dump truck 6, including a braking system and an air pressure detection device. The pressure gauge 1 of the air pressure detection device is used to detect the air pressure of the braking system, and the connector 2 of the air pressure detection device is connected to the braking system.

[0022] like Figure 2 As shown, the air pressure detection device is used to detect the air pressure of the braking system of the off-highway dump truck 6, including a pressure gauge 1 for measuring air pressure and a connector 2 for connecting the pressure gauge 1 to the braking system of the off-highway dump truck 6 so as to detect the air pressure in the braking system through the pressure gauge 1.

[0023] In the air pressure detection device, there is one pressure gauge 1 and multiple connectors 2. Multiple connectors 2 are used to selectively connect multiple brake chambers 5 of the braking system to the pressure gauge 1. The connectors 2 selectively detect the air pressure in the multiple brake chambers 5 through the pressure gauge 1, thereby quickly eliminating air leakage faults in the braking system. Furthermore, the same pressure gauge 1 is connected to each brake chamber 5 in turn, which saves on the production cost of the air pressure detection device. The connectors 2 are configured according to the actual interface status of their corresponding brake chambers 5, facilitating rapid detection of vehicle faults. In a further embodiment, there are multiple pressure gauges 1 and multiple connectors 2, with each connector 2 corresponding to one pressure gauge 1. Each connector 2 connects one brake chamber 5 in the braking system to the corresponding pressure gauge 1. Detecting the air pressure in that brake chamber 5 through the pressure gauge 1 not only quickly eliminates faults but also makes the connection between the pressure gauge 1 and the corresponding brake chamber 5 more reliable, and the data obtained from the pressure gauge 1 is more accurate.

[0024] The air pressure detection device also includes a first pipe 3 and a second pipe 4. The first pipe 3 connects the pressure gauge 1 to the connector 2, and the second pipe 4 connects the connector 2 to the brake chamber 5, so that the pressure gauge 1, the first pipe 3, the connector 2, and the second pipe 4 form an external pressure measurement circuit during measurement. The second pipe 4 includes a parking chamber pipe and a driving chamber pipe. The parking chamber pipe connects the connector 2 to the parking chamber 52 of the brake chamber 5, and the driving chamber pipe connects the connector 2 to the driving chamber 51 of the brake chamber 5. The connector 2 can selectively connect the parking chamber pipe and the driving chamber pipe to the first pipe 3, allowing the pressure gauge 1 of the air pressure detection device to selectively measure the air pressure in different chambers of different brake chambers 5. By using the pressure value of the pressure gauge 1, the vehicle's fault condition can be determined, thereby quickly troubleshooting the fault.

[0025] like Figure 1 As shown, the braking system includes multiple brake chambers 5, and multiple connectors 2 of the air pressure detection device correspond to the multiple brake chambers 5. The brake chambers 5 are connected to pressure gauges 1 through connectors 2, and the air pressure in different brake chambers 5 is detected by pressure gauges 1. The brake chambers 5 include a driving chamber 51 and a parking chamber 52. The connectors 2 of the air pressure detection device can be connected to the driving chamber 51 through the driving chamber pipe of the second pipe 4, and the connectors 2 can also be connected to the parking chamber 52 through the parking chamber pipe of the second pipe 4. The driving chamber 51 and parking chamber 52 of the corresponding brake chambers 5 can be selectively connected to pressure gauges 1. The air pressure in the driving chamber 51 or the parking chamber 52 can be selectively measured by pressure gauges 1, and the fault diagnosis of the vehicle braking system can be completed quickly and conveniently by using the results displayed by pressure gauges 1. The air pressure detection device includes multiple connectors 2, which are used to selectively connect multiple brake chambers 5 to pressure gauges 1. By selectively testing the air pressure in multiple brake chambers 5 through pressure gauges 1, the fault location of the braking system can be located through the value of pressure gauges 1, so as to eliminate the fault of the off-highway dump truck 6 and avoid safety accidents during vehicle operation.

[0026] In addition, the off-highway dump truck 6 also includes a handbrake and a foot brake 61, which are connected to the vehicle's braking system. When the handbrake or foot brake 61 is operated, it causes a pressure change in the brake chamber 5 of the braking system. An air pressure detection device is connected to the braking system of the off-highway dump truck 6 and is used to measure the air pressure in the driving chamber 51 and parking chamber of the brake chamber 5 when the handbrake or foot brake 61 is operated, thereby determining the specific location of the fault in the off-highway dump truck 6.

[0027] like Figure 3As shown, the detection principle of the air pressure detection device provided in this embodiment is as follows: The pressure gauge 1 of the air pressure detection device is connected to the driving chamber 51 or parking chamber 52 of the brake chamber 5 through the connector 2 and the second pipe 4. During detection, the handbrake is operated, and the pressure gauge 1 detects the air pressure in the chamber. The value of the pressure gauge 1 is used to determine whether the vehicle's braking function is normal. If an abnormality is found, the location of the fault in the braking system can be determined, and the fault can be eliminated. In a further embodiment, during detection, the foot brake 61 can be operated to cause a pressure change in the chamber of the brake chamber 5, so that the air pressure in the chamber can be detected by the pressure gauge 1.

[0028] The testing process of the air pressure testing device provided in this embodiment is as follows: When using the air pressure testing device, select one of the driving chambers 51 or parking chambers 52 of one brake chamber 5 to measure. The interface of the tested chamber is connected to the pressure gauge 1 through the second pipe 4, connector 2, and first pipe 3. The interfaces of each of the remaining brake chambers 5 are blocked with connector 2 to prevent air leakage during the testing process. After the connection is completed, operate the handbrake and use the pressure gauge 1 to measure the pressure of the driving chamber 51 or parking chamber 52 of the brake chamber 5. Observe the value displayed on the pressure gauge 1 to determine the fault condition of the chamber. Similarly, measure the air pressure of each chamber of each brake chamber 5 one by one in the same way, observe the value of the pressure gauge 1, and thus determine which chamber of which brake chamber 5 is faulty, thereby quickly eliminating the fault of the off-highway dump truck 6 braking system. In a further embodiment, the foot brake 61 can be operated to cause a pressure change in the chamber of the brake chamber 5, so that the air pressure of the chamber can be detected by the pressure gauge 1.

[0029] In summary, the above-described embodiments of this utility model provide an off-highway dump truck 6, including a braking system and an air pressure detection device. The braking system includes multiple brake chambers 5, each comprising a driving chamber 51 and a parking chamber 52. The driving chamber 51 is connected to a connector 2 and a pressure gauge 1 via a driving chamber pipe of a second pipe 4. The parking chamber 52 is connected to the connector 2 and pressure gauge 1 of the air pressure detection device via a parking chamber pipe of the second pipe 4. This allows the air pressure detection device to be fully adapted to the off-highway dump truck 6, enabling rapid inspection of the braking system malfunctions. Furthermore, when measuring the air pressure of the braking system using the air pressure detection device, one chamber of the brake chamber being measured is connected to the pressure gauge 1, while the remaining brake chambers 5 are blocked by connectors 2. The pressure of this chamber is measured to determine if it is faulty. By measuring the pressure of different chambers of different brake chambers 5 in the same manner, the location and cause of the fault can be identified, thereby quickly eliminating the faults in the off-highway dump truck 6.

[0030] like Figure 2As shown, another embodiment of this application also provides a pressure detection device, which can be, for example, the pressure detection device included in the above-described off-highway dump truck embodiment.

[0031] In summary, the air pressure detection device provided by the above embodiments of this utility model is used to detect the air pressure of the braking system of an off-highway dump truck 6. It includes a pressure gauge 1, a connector 2, a first pipe 3, and a second pipe 4. The pressure gauge 1 is connected to the connector 2 via the first pipe 3, and the connector 2 is connected to the brake chamber 5 via the second pipe 4. Multiple connectors 2 are available, allowing selection of the appropriate connector 2 based on the interface of the brake chamber 5. This enhances applicability, ensures compatibility with the off-highway dump truck 6, and improves the reliability of the air pressure detection results. The second pipe 4 includes a parking chamber pipe and a driving chamber pipe, respectively connected to two different chambers of the brake chamber 5. This allows the pressure gauge 1 to selectively test the air pressure of different chambers, thereby quickly identifying the location of vehicle malfunctions based on the pressure values ​​shown on the pressure gauge 1 and preventing safety issues such as reduced braking performance due to insufficient air pressure during vehicle operation.
