Abstract
The utility model discloses an electrical-hydraulic brake mechanism which comprises an oil cylinder, a centrifugal pump connected with the oil cylinder, a motor and a piston. A spline shaft is connected between the motor and the centrifugal pump. The oil cylinder is connected with the piston and drives the piston to move, and the piston is connected with a strut. The electrical-hydraulic brake mechanism combines the motor and a hydraulic device to achieve the brake of the component needing braking, and is simple in entire structure, and braking and releasing can be achieved simply by carrying out connecting and cutting off of a power supply of the motor in an operation process.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of electric hydraulic arrestment mechanism.
Background technique
Arrestment mechanism is to have to make moving element or movable machinery slow down, stop or keeping the device of functions such as halted state, is the mechanical parts that make the movement parts in the machinery stop or slowing down, and is commonly called as brake, lock; Arrestment mechanism applies certain active force by outer bound pair braking part position, apparatus to running applies the external force opposite with operating direction, utilize non-rotating element and stop the trend of rotation or the rotation of wheel with phase mutual friction between the rotatable member, thereby it is carried out to a certain degree forced brake.Usually be contained on the high speed shaft of equipment in order to reduce a braking moment and structure cun break, but the main equipment higher to security requirement (as mine hoist, elevator etc.) then is installed near on the lower velocity shaft of equipment working portion.
Mechanical operating part is stopped or slowing down the resisting moment that must apply be called braking moment.Braking moment is design, selects the foundation of break for use that its size is determined by pattern and the job requirement of machinery.The performance of used friction material directly influences braking process on the break, and the principal element that influences its performance is operating temperature and temperature rise speed.Friction material should possess high and stable friction factor and good wear resistance.
The model utility content
The technical problems to be solved in the utility model provides a kind of electric hydraulic arrestment mechanism simple in structure, simple to operate.
In order to solve the problems of the technologies described above, the utility model provides a kind of electric hydraulic arrestment mechanism, comprises oil cylinder, the centrifugal pump that is connected with oil cylinder, motor and piston, is connected with splined shaft between motor and the centrifugal pump; Oil cylinder connects piston and promotes the piston motion, and piston is connected with pillar.
Connect motor power, splined shaft drives centrifugal pump and rotates under the rotation of motor, the centrifugal force of the centrifugal pump that rotates rises the hydrodynamic pressure of oil cylinder bottom relatively, the jack-up piston moves upward, because pillar is connected with piston, pillar rises along with the rising of piston, and pillar is braked the parts of needs braking; Cut off motor power, centrifugal pump stops operating, and the hydrodynamic pressure of oil cylinder bottom descends relatively, and pillar and piston descend under the active force of deadweight, withdraws from the braking to the parts of needs braking.The utility model is with the braking that is used to uniting of motor and hydraulic pressure installation to realize to the parts of needs braking, and total is simple, only needs motor is carried out the connection of power supply and cut off just can realizing braking and unclamping in operating process.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the utility model embodiment's designs simplification schematic representation.
Embodiment
As shown in Figure 1, the utility model provides a kind of electric hydraulic arrestment mechanism, comprises oil cylinder 4, the centrifugal pump 3 that is connected with oil cylinder 4, motor 1 and piston 5, is connected with splined shaft 2 between motor 1 and the centrifugal pump 3; Oil cylinder 4 connects piston 5 and promotes piston 5 motions, and piston 5 is connected with pillar 6.
Connect motor 1 power supply, splined shaft 2 drives centrifugal pump 3 and rotates under the rotation of motor 1, the centrifugal force of the centrifugal pump 3 that rotates rises the hydrodynamic pressure of oil cylinder 4 bottoms relatively, jack-up piston 5 moves upward, because pillar 6 is connected with piston 5, pillar 6 rises along with the rising of piston 5, and 6 pairs on pillar needs the parts of braking to brake; Cut off motor 1 power supply, centrifugal pump 3 stops operating, and the hydrodynamic pressure of oil cylinder 4 bottoms descends relatively, and pillar 6 and piston 5 descend under the active force of deadweight, removes the braking to the parts of needs braking.The utility model is with the braking that is used to motor 1 and uniting of hydraulic pressure installation to realize to the parts of needs braking, and total is simple, only needs motor is carried out the connection of power supply and cut off just can realizing braking and unclamping in operating process.
Above-described only is preferred implementation of the present utility model, should be understood that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not influence effect and practical applicability that the utility model is implemented.
