Description
Technical Field
The utility model belongs to the technical field of commercial truck driver's cabin upset hydraulic system, concretely relates to truck driver's cabin hydraulic pressure upset hand charge pump with drainage function.
Background
In the current truck market at home and abroad, a scheme of integrating a drainage device on a flashlight pump to realize an oil discharge function is not available, in the prior art, a hydraulic overturning system of a cab needs to use a manual pump to fill hydraulic oil, the oil filling amount is not accurate, and the filled hydraulic oil exceeds the actual using amount of the hydraulic overturning system; in the whole vehicle running process, hydraulic oil in the manual pump jolts and vibrates along with the whole vehicle, the hydraulic cylinder is also killed along with the cab vibration, and in the killing process, the hydraulic oil pressure of the oil way changes circularly, and the oil can be sucked and discharged out of the hydraulic cylinder repeatedly. Due to the oscillation and loss of motion, the hydraulic oil and air form an oil mixture, and the pressure in the hydraulic roll-over system increases. In order to protect the manual pump shell and other hydraulic elements, the hydraulic turnover system needs to be exhausted for pressure relief or redundant hydraulic oil is discharged, and the space is enlarged to enable oil and gas in the oil-gas mixture to be separated rapidly. When using the relief valve to carry out the exhaust pressure release to hydraulic pressure upset system, oil-gas mixture easily discharges from the relief valve along with the air, and fluid can remain around the relief valve, pollutes manual pump case.
In view of the above, there is a need to develop a manual pump which can not pollute the housing of the manual pump, but can discharge excessive oil in the manual pump, so that the housing of the manual pump has enough space for separating oil-gas mixture.
Disclosure of Invention
In order to overcome the problem, the utility model provides a truck driver's cabin hydraulic pressure upset hand charge pump with drainage function is the hand charge pump that can exhaust pressure release, discharge unnecessary fluid, and it is too big to have solved commercial truck driver's cabin hydraulic pressure upset system fluid too much and driving a vehicle in-process hydraulic system formation oil-gas mixture pressure, the problem of hydraulic oil pollution hand charge pump shell during the pressure release.
The technical scheme of the utility model is realized like this:
the utility model provides a truck driver's cabin hydraulic pressure hand charge pump with drainage function, includes electric pump 1, relief valve 3 and hand pump 4, and electric pump 1 connects on hand pump 4, is provided with relief valve 3 on the hand pump 4, still includes drainage device 2, wherein 2 threaded connection of drainage device on 4 casings of hand pump and with the inside intercommunication of hand pump 4.
The drainage device 2 comprises a drainage tube 21, an oil guide tube joint 22, a one-way valve 23 and a pipe joint 24, wherein the drainage tube 21 is connected with the one-way valve 23 through the oil guide tube joint 22, the one-way valve 23 is embedded into the pipe joint 24, and the pipe joint 24 is in threaded connection with the shell of the manual pump 4 and is communicated with the interior of the manual pump 4.
The casing of the manual pump 4 is provided with an oil outlet hole with threads inside, and the pipe joint 24 is connected in the oil outlet hole in a threaded mode.
The utility model has the advantages that:
1. by controlling the opening pressure of the one-way valve, the phenomenon that the pressure is too high and the shell of the pump is damaged due to oil-gas mixture in the manual pump is prevented.
2. The one-way valve of the drainage device is opened under the action of pressure, the oil-gas mixture is discharged through the one-way valve, the drainage of the drainage pipe avoids polluting the shell and other parts, the discharge of the oil-gas mixture reduces the filling of excessive hydraulic oil in the pump, and the pump has enough space for facilitating the oil-gas separation in the oil-gas mixture.
Therefore, the utility model discloses can adjust hydraulic oil to optimum condition and avoid fluid to pollute in the pump automatically.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the drainage device of the present invention.
Wherein 1 electric pump, 2 drainage devices, 21 draft tubes, 22 oil guide tube joints, 23 one-way valves, 24 tube joints, 3 safety valves and 4 manual pumps.
Detailed Description
As shown in figure 1, the hydraulic overturning hand-operated electric pump with the drainage function for the truck cab comprises an electric pump 1, a safety valve 3, a hand-operated pump 4, a drainage device 2 and a safety valve 3, wherein the electric pump 1 is connected to the hand-operated pump 4, the safety valve 3 is arranged on the hand-operated pump 4, and the drainage device 2 is in threaded connection with an oil outlet hole in a shell of the hand-operated pump 4 and is communicated with the interior of the hand-operated pump 4.
The safety valve 3 is in threaded connection with an oil filling port of a shell of the manual pump 4.
As shown in fig. 2, the drainage device 2 includes a drainage tube 21, an oil conduit connector 22, a one-way valve 23 and a pipe connector 24, wherein the drainage tube 21 is connected with the one-way valve 23 through the oil conduit connector 22, the one-way valve 23 is embedded in the pipe connector 24, and the pipe connector 24 is in threaded connection with the housing of the manual pump 4.
The upper ends of the guide pipe 21 and the check valve 23 are both embedded in the oil guide pipe joint 22 and connected in the oil guide pipe joint 22, and the lower end of the check valve 23 is embedded in the pipe joint 24.
An oil outlet hole is added on the shell of the manual pump 4, a thread is arranged in the oil outlet hole, and a pipe joint 24 is connected in the oil outlet hole in a threaded mode. The safety valve 3 arranged on the manual pump 4 has an air suction function, and the drainage device 2 has functions of exhausting, discharging oil and draining oil. The safety valve 3 and the drainage device 2 jointly keep the pressure in the manual pump 4 stable.
During the running process of the whole vehicle, the hydraulic oil forms an oil-gas mixture in the process of braking. As the hydraulic system is easy to be filled with too much hydraulic oil, the remaining space of the manual pump 4 is too small, and oil-gas mixture oil and gas cannot be separated in time, the pressure in the pump is too high. When the pressure reaches the opening pressure of the one-way valve 3, the one-way valve 3 is opened, and the interior of the manual pump 4 is communicated with the outside through the drainage device 2. The oil-gas mixture is discharged through the one-way valve 3, the pressure in the pump is reduced, and the oil-gas mixture is drained through the drainage pipe 21 to avoid polluting the shell and other parts of the manual pump 4. The discharge of the oil-gas mixture reduces the filling of excessive hydraulic oil in the pump, and the pump has enough space to facilitate the oil-gas separation in the oil-gas mixture. The drainage device can automatically adjust the hydraulic oil in the pump to the optimal state and avoid the pollution of the oil.
