Abstract
The utility model discloses a safety rope stretcher which comprises a shell, wherein a steel wire cylinder device is mounted in the shell; a pothook is fixedly connected with an end face of the shell; a steel wire stretches out of a through hole on the other end face opposite to the end face; a brake gear is arranged on an end part of a rotating shaft of the steel wire cylinder device; a brake plate is hinged in the shell; one end of the brake plate is blocked in a gear tooth of the brake gear; a press spring is arranged under the bottom at the other end of the brake plate; a press rod is horizontally arranged in the shell above the middle part of the brake plate between the press spring and the gear; and the steel wire passes by the top of the press rod. If a force is suddenly applied, the brake plate is downward pressed by the press rod, one end of the brake plate is upward warped so as to clamp the gear, and a steel wire cylinder is tightly locked, so that a protecting function of preventing high-altitude falling is achieved.
Description
Technical field
The utility model relates to a kind of safety rope expansion bend.
Background technology
Existing safety belt is a kind of fixed range formula safety belt, with regard near point (2 meters) safe hitch point must be arranged in the operation area, as select longthening belt, and longthening belt can not shrink, and dilatory, inconvenient operation everywhere.If human body falls suddenly, the snap tension of safety belt can damage human body, if horizontal range is greater than during vertical range, not having protective effect apart from ground.
Summary of the invention
The purpose of this utility model is to provide a kind of safety rope expansion bend, and it is simple in structure, can pin timely steel wire rope, prevents its excessive stretching, improves staff's operating safety factor.
The purpose of this utility model is to realize like this, a kind of safety rope expansion bend, comprise housing, the wire rope roll cartridge is installed in the housing, affixed hook on one end face of housing, stretch out the through hole of steel wire rope from relative other end, the roller end of wire rope roll cartridge is equipped with a spragging gear, an articulated keep plate in housing, one end of keep plate snaps in the teeth of spragging gear, under the other end bottom surface of keep plate a stage clip is being set, is being horizontally disposed with a depression bar in the keep plate middle part upper shell between stage clip and the gear, steel wire rope is walked around from the depression bar end face.
When the utility model used, such as unexpected reinforcing, steel wire rope was strained suddenly, and the end that depression bar will press down keep plate, keep plate upwarps and blocks gear, thereby locked the playing of cable drum prevented the falling from high altitude protective effect.After the steel wire rope mistake power, under the effect of stage clip, keep plate resets, and spragging gear can automatic rotating, and steel wire rope just can normally stretch.The utility model is simple in structure, and is cheap, easy to use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is perspective view of the present utility model.
The specific embodiment
A kind of safety rope expansion bend as shown in Figure 1, comprises housing 8, and wire rope roll cartridge 1 is installed in the housing 8, and affixed hook stretches out the through hole of steel wire rope 5 from relative other end on the end face of housing.The roller end of wire rope roll cartridge 1 is equipped with a spragging gear 2, an articulated keep plate 3 in housing, one end boss 4 of keep plate 3 snaps in the teeth of spragging gear, one stage clip 6 is being set under the other end bottom surface of keep plate 3, be horizontally disposed with a depression bar 7 in the keep plate middle part upper shell between stage clip 6 and the gear 2, steel wire rope 5 is walked around from depression bar 7 end faces.
During use, such as unexpected reinforcing, steel wire rope 5 is strained suddenly, and the end that depression bar 7 will press down keep plate 3, keep plate 3 upwarps and blocks gear 2, thereby locked the playing of cable drum prevented the falling from high altitude protective effect.
