Further, described work box comprises: two cage plates, two nylon wheels, rope clamp, push rod spring, rope clamp spring and depression bars, and described two cage plates connect by rope clamp, make two cage plates to move simultaneously; Described depression bar is positioned at the top of two cage plates, can just prop up the cage plate that closes on when depression bar is swung; Described rope clamp is arranged on two cage plates; Described two nylon wheels are arranged at two cage plate belows; One end of described push rod spring is fixed in the work box inwall, and one in the other end and the cage plate links to each other, and the use by push rod spring can reduce the stop mechanism part three/, to compare with existing safety lock, structure is simplified greatly.
Further, described safety box comprises: two cage plates, rope clamp, push rod spring, rope clamp spring and depression bars, and described two cage plates connect by rope clamp, make two cage plates to move simultaneously; Described depression bar is positioned at the top of two cage plates, can just prop up the cage plate that closes on when depression bar is swung; Described rope clamp is arranged on two cage plates; One end of described push rod spring is fixed in the safety box inwall, and one in the other end and the cage plate links to each other, and the use by push rod spring can reduce 1/3rd with the stop mechanism part, compares with existing safety lock, and structure is simplified greatly.
Further, cage plate, rope clamp, depression bar, crucial stressed member material all adopt the 17-4PH corrosion-resistant steel, and intensity is big, non-corrosive in the working process.
Beneficial effect:
The present invention is simple and reasonable for structure, compact, mainly has the following advantages:
1) highly versatile is applicable to S type, α type gig and various hanging basket;
2) structure continuity, a safety lock has 2 cover cage plates and rope clamp to be used in combination;
3) braking force is strong, and load cable and safe steel rope are braked simultaneously, and braking force doubles;
4) simple in structure, inherent stop mechanism part number reduces 1/3rd than place where troops were originally stationed inclination safety lock.
5) durable, crucial stressed member key materials such as cage plate, rope clamp, push rod, fork and connecting rod all adopt the 17-4PH corrosion-resistant steel, and intensity is big, non-corrosive in the working process.

The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
Shown in Fig. 1-7, the two brake safes locks of the present invention comprise work box 1, safety box 2, working rope 10, safety rope 11 and control box 3, the linking together of described work box 1, safety box 2 and control box 3 orders, and working rope 10 is by work box 1 braking; Safety rope 11 is promptly settled the control box of two synchronous interactions by safety box 2 brakings in safety lock, when working rope exceeded the speed limit, work box and safety box were braked simultaneously, and braking force doubles.
Work box 1 comprises: two cage plate 7A, two nylon wheels 8, rope clamp 4A, push rod spring 6A, rope clamp spring 5A and depression bar 9A, and described two cage plate 7A connect by rope clamp 4A, make two cage plate 7A to move simultaneously; Described depression bar 9A is positioned at the top of two cage plate 7A, can just prop up the cage plate 7A that closes on when depression bar 9A swings; Described rope clamp 4A is arranged on two cage plate 7A; Described two nylon wheels 8 are arranged at two cage plate 7A belows; Push rod spring 6A one end is fixed in work box 1 inwall, and one among the other end and the cage plate 7A links to each other, and the use by push rod spring can reduce 1/3rd with the stop mechanism part, compares with existing safety lock, and structure is simplified greatly.
The algorithm of two brake safe locks is: the hypervelocity sensor of being made up of two nylon rollers in work box, two nylon rollers clamp load cable sensing rope speed, when working rope exceeds the speed limit, make the nylon roller rotate hypervelocity, thereby make coaxial centrifugal 13 of nylon roller 8 overcome back-moving spring and fly out, push rod 12 is rushed open, cause push rod 12 front ends to break away from connecting rod bearing, cause connecting rod 14 swings, the swing of connecting rod 14 drives depression bar 9A, the 9B swing, thereby drive the push rod spring 6A that is enclosed within work box 1 and the safety box 2 on the push rod, the 6B compression, cause the cage plate 7A of work box 1 and safety box 2,7B while conter clockwise is to lower swing, make rope clamp 4A, 4B clamps simultaneously to load cable 10 and safe steel rope 11, thereby makes whole hanging basket realize braking.When hanging basket promoted, push rod and top spring were pressed to clockwise direction with cage plate 7A, 7B, rope clamp 4A, 4B are divided open, and removed the braking of lock rope, realized logical rope, normal operation.
The present invention cooperates with conventional gig and is fit to use on any type of high-lift operation hanging cradle.Because this safety lock is different from the single braking fastening safety lock of existing use, synchronous clamping braking when having realized working rope and safety rope hypervelocity, so safe reliability doubles than original safety lock, and owing to adopt the push rod spring structure, total is simplified greatly than existing safety lock, and inherent stop mechanism part reduces 1/3rd.Realized two optimization that braking effect improves and immanent structure is simplified.
It should be noted that at last: the above only is the preferred embodiments of the present invention, be not limited to the present invention, although the present invention is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
