Description
Technical field
This utility model is related to a kind of electromagnetism screw rod brake unit and in particular to a kind of electromagnetism screw rod for lifting device
Brake unit.
Background technology
In recent years, developing rapidly with mechanical industry, labour force has obtained persistently liberating, and the life of people becomes more
Convenient, but thing followed machine security accident emerges in an endless stream, the moment threatens the security of the lives and property of people, in order to the greatest extent may be used
It is avoided that accident occurs, eliminates accident potential, create a comparatively safe working environment, constantly improve protection device gesture is must
OK.
Motor is widely used in every field, provides power, moment of torsion to support for lifting devices such as elevator, tower cranes, power down
Or power-off cause motor completely lose ability to work, high-altitude lifting thing fall, be one kind potentially high-risk machine security accident because
Element.
Utility model content
This utility model purpose is to provide a kind of electromagnetism screw rod brake unit for lifting device, can be in motor power down
Or reliable braking and separation during power-off.
To achieve these goals, this utility model employs the following technical solutions:
A kind of electromagnetism screw rod brake unit for lifting device, including brake screw, spring, slide block, guide rail, Magnet and
Electromagnetic switch；Brake screw is connected with the drive system of lifting device, and guide rail is connected with the support of lifting device, and covers on guide rail
There is spring, slide block can slide axially along guide rail, and slide block be connected with screw rod, electromagnetic switch is connected with the support of lifting device,
Electromagnetic switch is connected with Magnet, and electromagnetic switch circuit is connected on motor circuit.
Above-mentioned electromagnetism screw rod brake unit, brake screw is connected by the drive system of the bearing with bearing block and lifting device
Connect.
Above-mentioned electromagnetism screw rod brake unit, guide rail two ends are connected with the support of lifting device by fixed seat.
Above-mentioned electromagnetism screw rod brake unit, electromagnetic switch is threaded connection with Magnet.
Above-mentioned electromagnetism screw rod brake unit, guide rail is ball line slideway.
The beneficial effects of the utility model are:
Using said structure can the action immediately in motor power down or power-off, drive system is played with reliable, buffering system
Dynamic effect, can be prevented effectively from high-altitude and lift the harm that thing falls and intense impact causes, reduce accident rate, ensureing
The security of the lives and property aspect of people plays certain effect；It is cased with spring on guide rail, enables damping shock absorption function, effectively alleviate
Impact.
Brief description
The utility model is described in further detail below in conjunction with the accompanying drawings:
Fig. 1 is this utility model structural representation.
1 brake screw, 2 band bearing blocks, 3 fixed seats, 4 springs, 5 slide blocks, 6 Magnet, 7 guide rails, 8 electromagnetic switch.
Specific embodiment
For making the purpose of this utility model, technical scheme and advantage become more apparent, develop simultaneously enforcement referring to the drawings
Example, further describes to this utility model.
A kind of electromagnetism screw rod brake unit for lifting device, including brake screw 1, spring 4, slide block 5, guide rail 7, magnetic
Ferrum 6 and electromagnetic switch 8；Brake screw 1 is connected with the drive system of lifting device by the bearing with bearing block 2, and guide rail 7 is rolling
Pearl line slideway, guide rail 7 two ends are connected with the support of lifting device by fixed seat 3, and are cased with spring 4 on guide rail 7, slide block 5
Can slide axially along guide rail 7, and slide block 5 is connected with screw rod 1, electromagnetic switch 8 is connected with the support of lifting device, electromagnetic switch
8 are threaded connection with Magnet 6, and electromagnetic switch 8 circuit is connected on motor circuit.
Utility model works process is as follows: during normal work (energising), electromagnetic switch 8 is failure to actuate, Magnet 6 adhesive slide block
5, realize slide block 5 and position and fix, anti-limited slip block 5 contact by mistake with brake screw 1 it is ensured that slide block 5 and brake screw 1 be in non-
Contact condition, when accident power-off or power down occur, electromagnetic switch 8 action, stretch out push rod promotion and move forward with female thread slide block 5,
The freely falling body that high-altitude lifts thing leads to brake screw 1 to rotate, and both actions make slide block 5 and brake screw 1 threaded,
Slide block 5 continues to move forward under brake screw 1 turning effort, compression spring 4, in the presence of counteracting force, brake screw 1 rotating speed
It is gradually lowered, is finally stopped rotation, realize reliable braking, after switching on power, controlled motor inverts, and brake screw 1 promotes slide block
Move until both completely disengage from afterwards, electromagnetic switch 8 resets simultaneously, simple to operate, separating effect is reliable.
Above-mentioned specific embodiment is only concrete case of the present utility model, is not to make other forms to this utility model
Restriction, any those skilled in the art are changed or are modified as being equal to possibly also with the technology contents of the disclosure above
The equivalent implementations of change.But on the premise of every know-why without departing from this utility model, according to of the present utility model
Any simple modification, equivalent variations and remodeling that technical spirit is made to embodiment of above, all should fall into of the present utility model
Scope of patent protection.
