The magnetic power eccentric type brake is characterized in that the upper and lower ends of the brake support adopt close structures, a steel strand is fixed at one side of a pylon, the centre part of the brake support adopts an opened structure, the permanent magnet is installed in the groove of the brake support, a pin axle is arranged inside the hole at the lower part of the brake support, to form an embedded structure with the brake support through an installation groove; a hanging hole is arranged at the upper part of the brake block, the safety belt hanging loop is looped with the hanging hole, an assistant brake point and a main brake point are respectively arranged at the lugs at the upper and lower parts where the brake block is adjacent to the brake support, and a support brake point is arranged at the lower part of the brake support. The magnetic power eccentric type brake has the advantages that the permanent magnet is arranged on the support, to improve braking reliability; the cost is lower, and the installation is convenient; the magnetic power eccentric type brake ensure that the steel strand which used as orbit to perform the anti-falling in height is realized, the corrosion-resisting property is good, and the labor intensity is reduced.
Description
Technical field
The utility model relates to a kind of magnetic force eccentric wheel type brake.
Background technology
Existing special-purpose track brake, mostly by the link that is connected with the human body safety belt, the braking arm of force, the compositions such as bearing of brake(-holder) block, the convenient assembly pulley that slides in orbit, parcel track, indivedual forms increase and decrease to some extent, but these brake apparatus all can only use on specific track, as first cast track, I shape track, fluted body track etc., the cost determination of track the utilization of these brake apparatus; These install most structure more complicated, and are carried by personnel oneself, have increased user of service's workload.And the differential speed type brake is similar to the safety belt that general-utility car uses; generally form by shell, clockwork spring dish, centrifugal card, cable wire or special tightrope; there is following difficulty in this anti-fall device to process safe protection about the work high above the ground personnel: with high costs; the differential speed type device must be fixed on the clockwork spring dish eminence top, and the long-term use of clockwork spring dish is easily followed the string, rust is turbid easily for steel strand wires or special tightrope.Protection when in addition, same device generally only limits to operating personnel's work high above the ground transposition.
The utility model content
The purpose of this utility model provides a kind of magnetic force eccentric wheel type brake, and is higher with the price that overcomes existing cost, can't realize the deficiency that the high-altitude is anti-fall, operating personnel's workload is bigger.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of magnetic force eccentric wheel type brake, comprise Der Bremssattel, brake block, permanent magnet, safety belt link, the upper/lower terminal of described Der Bremssattel is a closing structure, steel strand wires are fixed on a side of iron tower, described Der Bremssattel middle part is an open architecture, described permanent magnet is installed in the groove of Der Bremssattel, and the inside, hole of Der Bremssattel bottom is provided with bearing pin, forms nested structure by mounting groove and Der Bremssattel; Described brake block top is provided with hanging hole, hanging hole socket safety belt link, and the projection place, upper and lower part that brake block and Der Bremssattel are adjacent is provided with auxiliary braking point and main brake point respectively, and the bottom of Der Bremssattel is provided with the bearing braking point.Described brake block, bearing pin and main brake point form cam or eccentric wheel structure, and the distance of hole and bearing braking point is greater than the steel strand wires diameter, and the distance of main brake point and bearing braking point is less than the steel strand wires diameter.
The beneficial effect of magnetic force eccentric wheel type brake described in the utility model is: set up permanent magnet on bearing, improved the reliability of braking; Simple in structure, cost is lower, easy for installation; Make steel strand wires do track and carry out the high-altitude fall arrest and be achieved, can use simultaneously for many people; Have excellent corrosion resisting performance, reduced field work personnel's labour intensity to greatest extent.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described magnetic force eccentric wheel type of the utility model embodiment brake.
Among the figure:
1, steel strand wires; 2, Der Bremssattel; 3, brake block; 4, bearing pin; 5, hanging hole; 6, permanent magnet; 7, main brake point; 8, auxiliary braking point; 9, safety belt link; 10, bearing braking point; 11, mounting groove; 12, hole.
The specific embodiment
Shown in Fig. 1-2, the described magnetic force eccentric wheel type of the utility model embodiment brake, comprise Der Bremssattel 2, brake block 3, permanent magnet 6, safety belt link 9, on the described Der Bremssattel 2, following two ends are closing structure, thereby guarantee relative distance with steel strand wires 1, the side that steel strand wires 1 are fixed on iron tower for the staff along steel strand wires iron tower up and down, described Der Bremssattel 2 middle parts are open architecture, thereby guarantee effective activity of brake block 3, described permanent magnet 6 is installed in the groove of Der Bremssattel 2,12 inside, hole of Der Bremssattel 2 bottoms are provided with bearing pin 4, bearing pin 4 can be cast into integral body with brake block 3, forms nested structure by mounting groove 11 and Der Bremssattel 2; Described brake block 3 tops are provided with hanging hole 5, hanging hole 5 socket safety belt links 9, and brake block 3 and Der Bremssattel 2 adjacent projection places, upper and lower part are provided with auxiliary braking point 8 and main brake point 7 respectively, and the bottom of Der Bremssattel 2 is provided with bearing braking point 10.Described brake block 3, bearing pin 4 form cam or eccentric wheel structure with main brake point 7, the distance of hole 12 and bearing braking point 10 is greater than the diameter 10 of steel strand wires, the distance of main brake point 7 and bearing braking point 10 is less than the steel strand wires diameter, and the design of auxiliary braking point 8 can make personnel obtain effective support by the grip of staff during iron tower about normal.
The described magnetic force eccentric wheel type of above the utility model embodiment brake, when human body normally moves up and down, hand-held this brake, the safety belt link 9 that is connected with human body is connected with hanging hole 5, the hole 12 and the steel strand wires of brake block 3 leave enough gaps, Der Bremssattel 2 is because of the attraction of permanent magnet 6, though steel strand wires 1 form certain friction, can not influence the normal of human body and move; In case human body falls suddenly, staff leaves brake, Der Bremssattel 2 is because of the attraction of permanent magnet 6, form certain friction with steel strand wires 1, decrease speed is far below the human body free-fall velocity, brake block 3 is that the center of circle A takes place to rotation because of the deadweight reason with bearing pin 4, along with human body further descends, when rotating to main brake point 7 over against bearing braking point 10, because of the distance between main brake point 7 and the bearing braking point 10 less than the steel strand wires diameter, the impulsive force of the downward freely falling body of human body can be passed through safety belt link 9, hanging hole 5, brake block 3 is that lever forms powerful pressure at main brake point place to steel strand wires 1 with bearing pin 4, steel strand wires 1 pass through bearing braking point 10 with Der Bremssattel 2 simultaneously, form braking thereby main brake point 7 is converted into huge frictional force.
