Description
Technical field
It is applied to the mating hydraulic systems such as elevator, track staircase the utility model is related to a kind of, is needed in stall
There is the equipment of safety arrestment.
Background technology
When declining, when decrease speed reaches 1.6 times of normal running speed, safety moves for common elevator and staircase
Make, bore drum and lock, by output gear and rack brake, while control circuit powers off.When be caught in gear foreign matter or oil and water lead to
The sealing device for crossing damage enters inside its cone drum catching device, will seriously affect braking effect or even accident occurs.
Invention content
The utility model provide it is a kind of be swift in response, safety and the passive water brake control system for not needing to electric power.
The utility model is achieved by the following technical solution：A kind of passive water brake control system, it is main
Technical characteristic is that the hydraulic control system includes fuel tank, hydraulic pump, overflow valve, check-valves, hand-operated valve, speed governing valve, braking
The transmission shaft of cylinder, wherein hydraulic pump is connected with elevator universal driving shaft, and the import of hydraulic pump is connected with shut-off valve, shut-off valve and oil suction
Filter is connected, and the outlet of hydraulic pump is connected with the import of check valve, and check valve is connected with the import of check-valves, non-return valve outlet and
Checking cylinder is connected, and check-valves is connected simultaneously with hand-operated valve, hand-operated valve connected tank, and check valve is connected simultaneously with speed governing valve, check valve
Also it is connected with overflow valve, speed governing valve outlet is connected with overflow valve outlet, and the two outlet takes back oil strainer.
The utility model is calculated and is tested by a large amount of, is confirmed that the system can realize gradual braking, can be carried significantly
The security performance of high equipment, brake force is adjustable, can arbitrary adjusting brake moment for various products.
When being worked due to the system, whole elements do not need to electric drive, so even if when having a power failure, it can also be steady safely
Fixed work.The equipment such as elevator and staircase for being completely dependent on electric power, unfailing performance is more preferable, and the scope of application is wider.
Description of the drawings：
Fig. 1 is the control system schematic diagram of the utility model.
Specific embodiment：
As shown in Figure 1, this passive water brake control system includes fuel tank 1, and hydraulic pump 6, overflow valve 12, check-valves 13,
Hand-operated valve 10, speed governing valve 9, the transmission shaft of checking cylinder 7, wherein hydraulic pump are connected with elevator universal driving shaft 5, the import of hydraulic pump 6 and
Shut-off valve is connected, and shut-off valve is connected with oil absorption filter 4, and the outlet of hydraulic pump is connected with the import of check valve 8,8 He of check valve
The import of check-valves 13 is connected, and the outlet of check-valves 13 is connected with checking cylinder, and check-valves 13 is connected simultaneously with hand-operated valve 10, hand-operated valve
10 connected tanks, check valve 8 are connected simultaneously with speed governing valve 9, and check valve 8 is also connected with overflow valve 12, and speed governing valve 9 exports and overflow valve
12 outlets are connected, and the two outlet takes back oil strainer 14.There are liquid level gauge 2, air filter 3, oil absorption filter 4 and pressure in figure
Power table 11.
Speed governing valve 9 is employed, and the braking of the equipment such as elevator and track staircase is realized by checking cylinder 7.By a large amount of
Calculating and experiment, confirm that the system can realize gradual braking, the security performance of equipment can be greatly improved, brake force can
It adjusts, it can arbitrary adjusting brake moment for various products.
The description of braking process：
The output shaft 5 that elevator drives drives hydraulic pump 6 to work, by hydraulic oil be output to brake cylinder 7 and speed governing valve 9 into
Mouthful, speed governing valve have built-in pressure and temperature compensation, can fine-tune by flow, when elevator rotating speed is in fixing speed
Within when, hydraulic pump discharge fluid fuel tank is returned to by speed governing valve.When elevator rotating speed is more than fixing speed, the row of hydraulic pump
The fluid flow gone out is more than the flow that speed governing valve is adjusted, and beyond part, fluid enters oil cylinder, and oil cylinder starts to brake, and is needed when reaching
During the braking moment wanted, fuel tank is returned to by overflow valve 12 beyond part fluid.Due to having the effect of the non-return of check-valves 13, oil cylinder
It can continue to keep on-position, stop elevator safety.When needing to release braking, hand-operated valve 10 is only needed to commutate, oil cylinder
It retracts, releases braking.Hand-operated valve 10 is positioned with steel ball, can prevent from malfunctioning.
During power failure can also trouble free service, when being worked due to the system, whole elements do not need to electric drive, so even if
It, can also safe and stable operation when having a power failure.The equipment such as elevator and staircase for being completely dependent on electric power, unfailing performance is more preferable,
The scope of application is wider.
