Description

Technical Field

[0001] This utility model belongs to the field of automotive controller technology, and specifically relates to a remote controller. Background Technology

[0002] Fire trucks are special vehicles used for firefighting and rescue. They are mainly divided into water tanker trucks, foam trucks, and ladder trucks. Water tanker trucks carry a large amount of water and a high-pressure water pump for ordinary fires; foam trucks spray foam liquid and are suitable for oil or chemical fires; ladder trucks are equipped with a high-altitude lifting platform and can rescue people trapped in high-rise buildings. Fire trucks are usually equipped with warning lights and sirens to quickly reach the scene and are one of the most important disaster relief tools for firefighters.

[0003] Traditional fire trucks control the booster by pressing a pedal from inside the driver's cab. Oil from the master pump reservoir is then pumped into the booster's oil chamber, and the booster's hydraulic pressure pushes a piston, causing the push rod to extend its stroke and disengage the clutch. This method not only increases the need for personnel but may also prolong response time, affecting firefighting and rescue efficiency. To address these issues, we provide a remote controller. Utility Model Content

[0004] The purpose of this invention is to provide a remote controller to address the problem mentioned in the background art: the traditional method of controlling the booster in fire trucks involves pressing a pedal from inside the driver's cab, which in turn draws oil from the master pump reservoir into the booster's oil chamber. The booster's oil pressure then pushes the piston, causing the push rod to output its stroke and disengage the clutch. This method not only increases the need for personnel but may also lead to longer response times and affect the efficiency of firefighting and rescue operations.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a remote controller, including a cylinder, a solenoid valve is provided on one side of the cylinder, an oil pump is provided on the other side of the cylinder, a piston is sleeved inside the cylinder, a sealing ring is sleeved on the surface of the piston, a high-pressure sealing ring is sleeved on the surface of the piston, a spring is sleeved on one end of the piston, and a plurality of oil passage holes are opened on one end of the piston and on the side of the high-pressure sealing ring.

[0006] Preferably, the oil pump is fitted with an oil seal inside, one side of which abuts against a gasket, and a first retaining ring is fitted inside the oil pump, one side of which abuts against the gasket, and a waterproof gasket is fitted at one end of the oil pump.

[0007] Preferably, the oil pump has a venting bolt threaded to its top vent port, and a first bolt is fitted inside the oil pump, with one end of the first bolt threaded to the cylinder.

[0008] Preferably, the intake and exhaust ports at the bottom of the cylinder are fitted with a muffler, and the intake and exhaust ports at the bottom of the cylinder are fitted with a second retaining ring, the top of the second retaining ring abutting against the muffler.

[0009] Preferably, the air outlet of the solenoid valve is connected to the cylinder, a second bolt is sleeved inside the solenoid valve, one end of the second bolt is threaded to the cylinder, and an air inlet connector is threaded to the air inlet of the solenoid valve.

[0010] This utility model has the following beneficial effects: This device controls air pressure through an energized solenoid valve to drive a piston, cutting off the oil circuit between the main pump and the booster. A high-pressure sealing ring stabilizes the output oil pressure to the booster's oil chamber. Simultaneously, the piston compresses the spring to store energy, and the oil pressure drives the booster piston, causing the push rod to extend its stroke and quickly disengage the clutch. When operation stops, the solenoid valve is de-energized, the spring automatically resets, driving the piston back to its original position, and the booster push rod retracts synchronously to engage the clutch. The entire process requires no intervention from personnel inside the driver's cab. This innovative device moves the clutch control end outside the driver's cab, enabling remote and precise control of the fire truck's clutch. It avoids the drawbacks of traditional operations requiring driver assistance, allowing a single person to complete all operations outside the vehicle. This reduces manpower requirements and improves emergency response efficiency, making it particularly suitable for the critical, time-sensitive operations of firefighting.

[0016] Specifically, oil pump 3 has an integrally machined oil circuit interface on one end and the back. The interface at one end of oil pump 3 is connected to the booster through a high-pressure oil pipe, and the interface on the back of oil pump 3 is connected to the master pump through another high-pressure oil pipe. When the device is not working, the master pump and the booster are connected by the cooperation of oil pump 3 and oil passage holes. The number of oil passage holes is preferably six, but those skilled in the art can adjust the number according to actual needs. By setting oil passage holes, the surface of piston 4 is provided with an annular groove that matches the sealing ring 5 and the high-pressure sealing ring 6. Piston 4 drives sealing ring 5 to slide inside cylinder 1, which can effectively improve the sealing performance between piston 4 and the inner wall of cylinder 1. Piston 4 drives high-pressure sealing ring 6 to slide inside oil pump 3, which can effectively improve the sealing performance between piston 4 and the inner wall of oil pump 3. By setting spring 7, piston 4 can be effectively driven to reset.

[0017] refer to Figure 2 The oil pump 3 is fitted with an oil seal 8 inside, and a gasket 9 abuts against one side of the oil seal 8. A first retaining ring 10 is fitted inside the oil pump 3, and one side of the first retaining ring 10 abuts against the gasket 9. A waterproof gasket 11 is fitted at one end of the oil pump 3. The piston 4 slides inside the oil seal 8 to prevent oil from flowing into the cylinder 1. By setting the gasket 9 and the waterproof gasket 11, the oil seal 8 can be effectively limited. The oil pump 3 has a first groove that matches the first retaining ring 10 inside. By setting the waterproof gasket 11, the sealing at the connection between the cylinder 1 and the oil pump 3 can be effectively improved.

The piston 4 moves through the intake and exhaust ports to balance the pressure difference between the inside and outside of the cylinder 1. By setting the muffler 13, the sound of intake and exhaust can be reduced. A second slot adapted to the second retaining ring 17 is opened inside the intake and exhaust ports. The second retaining ring 17 limits the position of the muffler 13.

[0020] refer to Figure 1 The air outlet of the solenoid valve 2 is connected to the cylinder 1. The inside of the solenoid valve 2 is fitted with a second bolt 16.

By setting the second bolt 16, the solenoid valve 2 can be bolted to the cylinder 1. By setting the air inlet connector 15, it is easy to connect to the air source pipe.

[0021] Brief description of operation: Press the upper structure controller, solenoid valve 2 is energized and opened, and the device starts working. Piston 4 drives high-pressure sealing ring 6 to move and cut off the oil circuit between the main pump and the booster. Piston 4 outputs oil pressure to the booster oil chamber through high-pressure sealing ring 6. At the same time, piston 4 drives spring 7 to compress. The oil pressure pushes the booster piston, thereby causing the push rod to output stroke and disengage the clutch. Press the stop button on the upper structure controller, solenoid valve 2 is de-energized, causing spring 7 to reset and drive piston 4 back to its original position. The booster push rod returns to its original position, and the clutch engages. The above operations can be completed outside the cab. This device is mainly used in fire trucks, transferring the control terminal from inside the cab to outside the cab, and eliminating the need for personnel to operate it inside the cab.
