Background technology
In Research Work of Power Transmission Line, it is often necessary to which maintainer climbs up iron tower operation, it is contemplated that the reason such as cost, it is difficult to accomplish
Anti-fall guide rail is installed in every base shaft tower, this means that staff during Deng Ta, there is no the guarantor of safety protective tools
Shield, once there is the fracture of pin nail or foot position situations such as there is deviation, it is more likely that there is personnel's falling accident.
The content of the invention
The purpose of the present invention is:The magnetic fall arrest protection dress of body-worn when a kind of confession maintainer climbing shaft tower is provided
Put and its magnetic field control method, can contact condition between trick and shaft tower during real-time monitoring staff climbing, and then
By magnetic absorption control, the generation of falling accident is prevented.
The technical scheme that the present invention takes is specially:A kind of magnetic fall protection equipment, including back belt type safety belt sheet
Body, power subsystem, and control unit, field generating unit and the contact condition collection list of working power are provided by power subsystem
Unit;
Power subsystem and control unit are fixed on safe band body;
Field generating unit includes that at least 4 groups correspond to 4 magnetic field generators at position of both hands and both feet and can send out magnetic field respectively
The fixed mechanism that raw device is fixed in gloves or boots;Magnetic field generator and fixed mechanism are connected safe band body;Magnetic field occurs
The control end connection control unit of device;
Contact condition collecting unit is correspondingly arranged in both hands and double-legged 4 position sensors at position respectively including at least 4, respectively
The signal output part connection control unit of position sensor;
Each position sensor gathers the contact condition information between corresponding position and shaft tower, and the information transfer that will be collected respectively
To control unit;Control unit is produced for adsorbing shaft tower according to the contact condition information for receiving, control magnetic field generator
Magnetic field, or stop producing magnetic field.
In the present invention, control unit can be using microcontroller such as single-chip microcomputer etc..Magnetic field generator can using it is existing can
The miniature or small-sized magnetic field generator product of high-intensity magnetic field is produced, control unit is passed through the size of current of magnetic field generator by control
Control the size in magnetic field, it is ensured that can be adsorbed in staff on shaft tower when occurring by magnetic field.In use, staff first will
With apparatus of the present invention are worn on, then climb shaft tower.During staff's climbing shaft tower, contact condition collecting unit
Each position sensor can induce the contact condition between the trick position of staff and shaft tower, and control unit can be according to each portion
The contact condition of position judges work at present personnel with the presence or absence of falling risk, and is produced for adsorbing by controlling magnetic field generator
The magnetic field of shaft tower so that staff can be adsorbed on shaft tower by related, it is to avoid falling risk.
Preferably, in the present invention, position sensor is installed in gloves or boots, the position of correspondence palm or sole.It is excellent
Choosing, in the present invention, the position sensor is pressure sensor.In climbing, if palm sole touches shaft tower, position
Sensor can sense pressure, and whether control unit can sense that pressure judges whether staff has according to each sensor
Falling risk.
Preferably, the position sensor uses proximity metal sensor.Because shaft tower is usually metal material, approach
Formula metal sensor is existing product, and it has particular application as prior art.Additionally, position sensor can also use supersonic sensing
Device etc..
Preferably, in the present invention, each group magnetic field generator and fixed mechanism at both hands and double-legged position are respectively by connection
The connected safe band body of band, connect band is processed with safe band body using same material.I.e. connect band is of safety belt
Point, it is integrated with seat belt body in processing to process, the pulling force of high intensity can be born in moment of falling.

Creep work.
Invention additionally discloses a kind of magnetic field control method based on above-mentioned magnetic fall protection equipment, including step:
It is four contact points that S1 defines four positions of both hands both feet, and position sensor detects four between contact point and shaft tower
Contact condition, and by contact condition information transfer to control unit;
S2 control units receive four contact condition information of contact point, judge in current four contact points, are in contact with shaft tower
Contact point number:
If number is 4, control power subsystem is not powered to magnetic field generator
If number is 3, control power subsystem is passed through electricity to the magnetic field generator in 3 points positioned at two diagonal contact points
Stream so that two contact points on this is diagonal produce magnetic field, with related corresponding hand and foot's absorption shaft tower;
If number is 2, control power subsystem is passed through electricity to the magnetic field generator on two contact points currently being contacted with shaft tower
Stream so that magnetic field generator produces magnetic field, with the corresponding hand of related contact point or foot's absorption shaft tower.
The present invention in use, when during staff climbs in one it is diagonal on hand and foot leave simultaneously
Shaft tower, then position sensor also detect 2 points contact states, be also now the presence of falling risk, control unit control two
Lead to high current on individual contact point so that two contact points adsorb shaft tower.When the hand and foot that leave shaft tower regain one's grip on shaft tower
When, then position sensor detects 4 states of contact point contact again, and now magnetic field disappears, and staff can arbitrarily control
Trick continues to climb work.And work as position sensor and detect and be not in contact with a little being contacted with shaft tower, or only one of which contact point
During contact, the absorption of a point cannot realize the purpose for avoiding falling, while in order to avoid the collision produced by magnetic force is endangered
Danger, then do not produce magnetic field, can now utilize the real-time falling guard of other safeguard measures, such as insures rope.
Further, in the present invention, in four contact points, when there is 3 contact points to be contacted with shaft tower, magnetic field generator leads to
The electric current for entering is denoted as A1;When there is 2 contact points to be contacted with shaft tower, the electric current that magnetic field generator is passed through is denoted as A2;Electric current A1 is small
In electric current A2.I.e. two-point contact when falling risk be more than three point contact when falling risk, magnetic during corresponding two-point contact
Attached power also compared with three point contact when it is bigger.Preferably, electric current A2 is the twice of electric current A1.This set can also bigizationner subtract
Few influence of the magnetic adsorbability to staff's climbing motion.
Beneficial effect
Apparatus of the present invention simple structure and more light, is easy to wearing, it is easy to popularize.And work is had substantially no effect in application process
The climbing action of personnel, while contact condition that can be between real-time detection climbing personnel's trick and shaft tower, so that as needed
The magnetic field generator at control trick position produces magnetic field absorption affinity so that corresponding site is mutually adsorbed with shaft tower, so as to reduce fall
Danger, improves operating efficiency and security, can effectively protect the life security for stepping on tower personnel.
