Description

Technical Field

[0001] This utility model belongs to the field of hydraulic station technology, specifically relating to a waterproof roadblock hydraulic flap hydraulic station. Background Technology

[0002] A roadblock flap is an underground security device that achieves rapid lifting and lowering through a mechanical structure. The main body consists of a steel flap, a drive system, and a control system. Under normal conditions, the flap is flush with the ground to ensure passage. In an emergency, it can be quickly raised to form a physical barrier to block vehicle passage. In existing technologies, the drive system of roadblock flaps is usually hydraulically or electrically driven, and it can only work when the power is on. When the drive system is de-energized, the working status of the roadblock cannot be controlled. Utility Model Content

[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a waterproof hydraulic tilting station for road barriers, so as to solve the problems mentioned in the background art.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A waterproof hydraulic barrier tilting unit includes an oil tank, in which a motor and an oil pump are installed and connected. The motor and oil pump are driven together. An oil tank cover is sealed to the upper side of the oil tank. A stacking block is installed and connected to the upper side of the oil tank. The stacking block is connected to the oil pump. A hydraulic lock is connected to one side of the stacking block. A solenoid directional valve is installed and connected to the hydraulic lock. Two tubular one-way throttle valves are installed and connected to the other side of the stacking block. A manually operated normally closed solenoid valve connected to the passage is provided on the side of the stacking block.

[0006] Furthermore, the outside of the oil tank is fitted with a level thermometer for observing the hydraulic oil level and temperature.

[0007] Furthermore, the oil pump inlet is equipped with an oil suction filter.

[0008] Further specifying, a T-joint is connected between the two tubular one-way throttle valves and the oil outlet of the stack block, and the two T-joints are connected to an emergency manual pump through a pipeline, and the emergency manual pump is connected to the hydraulic oil in the oil tank through a pipeline.

[0009] Furthermore, a connecting bracket is assembled between the fuel tank cover and the motor.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Terms such as “comprising” or “including” mean that an element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

[0026] like Figure 1-4 As shown, a waterproof roadblock hydraulic flap hydraulic station includes an oil tank 1. A motor 2 and an oil pump 3 are installed and connected inside the oil tank 1. The motor 2 and the oil pump 3 are connected in a transmission manner. An oil tank cover 101 is sealed and connected to the upper side of the oil tank 1. A stacking block 4 is installed and connected to the upper side of the oil tank 1. The stacking block 4 is interconnected with the oil pump 3. A hydraulic lock 5 is connected to one side of the stacking block 4. An electromagnetic reversing valve 6 is installed and connected to the hydraulic lock 5. Two tubular one-way throttle valves 7 are installed and connected to the other side of the stacking block 4. A manually operated normally closed solenoid valve 8 connected to the passage is provided on the side of the stacking block 4.

[0027] In this embodiment, two tubular one-way throttle valves 7 are connected to the hydraulic flap of the roadblock. One valve is used for oil discharge, and the other for oil return. The hydraulic oil passing through the tubular one-way throttle valves 7 can only flow in one direction, controlling the operation of the roadblock flap. When oil is discharged, the roadblock flap rises to prevent vehicles from passing; when oil is returned, the roadblock flap is flattened, allowing vehicles to pass normally. The oil discharge and return are controlled by the hydraulic lock 5 and the solenoid directional valve 6. The hydraulic lock 5 achieves an interlock function through a one-way valve. When the spool valve is in the neutral position, the hydraulic lock 5 can lock the two oil circuits of the stack block 4, ensuring that it remains stationary; when... When the slide valve switches positions, the hydraulic lock 5 will open or close the oil circuit accordingly, controlling the on / off state of the two oil circuits. After power failure, the pressure of the hydraulic oil will gradually decrease, but the hydraulic control check valve in the hydraulic lock 5 will remain locked to prevent oil flow, thus maintaining the original state of the roadblock. The manual normally closed solenoid valve 8 controls the on / off state of the two circuits when energized. After power failure, the manual normally closed solenoid valve 8 is in the closed state. By manually controlling the manual normally closed solenoid valve 8, the pressure of the two oil circuits can be released. In the absence of power, the tipper roadblock can return to its original position to ensure normal vehicle passage.

[0028] Reference Figure 3 A level thermometer 9 for observing the hydraulic oil level and temperature is mounted and connected to the outside of the oil tank 1. In this embodiment, the level and temperature of the hydraulic oil in the oil tank 1 are observed through the level thermometer 9.

[0029] Reference Figure 4 An oil suction filter 10 is installed and connected to the oil inlet of the oil pump 3. In this embodiment, the oil suction filter 10 is used to filter the oil to prevent impurities in the oil tank 1 from entering the stack block 4 through the oil suction filter 10, thereby affecting the operation of the valve.

[0030] Reference Figure 3 A three-way connector 11 connects the two tubular one-way throttle valves 7 to the oil outlet of the stack block 4. The two three-way connectors 11 are connected to an emergency manual pump 12 via pipelines. The emergency manual pump 12 is connected to the hydraulic oil in the oil tank 1 via pipelines. In this embodiment, by setting up the emergency manual pump 12, the oil outlet and return of the tubular one-way throttle valves 7 can be manually realized in the event of a power outage, thereby realizing the lifting and lowering of the roadblock, and the hydraulic lock 5 closes the passage of the stack block 4.

[0031] Reference Figure 4 A connecting bracket 13 is assembled and connected between the fuel tank cap 101 and the motor 2. In this embodiment, the motor 2 is connected to the fuel tank cap 101, so that the motor 2 can be separated from the fuel tank 1. When a fault occurs, the motor 2 and the fuel tank cap 101 can be removed for easy repair or replacement.

[0032] Reference Figure 2An overflow valve 14 is provided on the front side of the stack block 4. In this embodiment, the overflow valve 14 is used for constant pressure overflow, pressure stabilization, system unloading, and safety protection.
