Description
Technical field:
The utility model relates to the supporting use of a kind of and special vertical rod, is used for the work high above the ground personnel and prevents from the protector that falls in the air in the process of ascending a height.
Background technology: the truck work personnel can tie up to safety belt on the firm member when work high above the ground, play the effect that prevents that the high-altitude from falling.But ascend a height, in the two-way process, fall arrest safeguard protection problem solves as yet fully.Fall protection equipment mainly is made of fall arrest protector and the vertical rod supporting with it, and in existing fall arrest protector, there are shortcomings such as complex structure, use inconvenience in great majority.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming of existing fall arrest protector, provides a kind of simple in structure, easy to use, is ascending a height, is preventing from the protector that falls in the air in the two-way process for the work high above the ground personnel.
The utility model, comprise rigid body and case, the front end of body is a hook portion, its end is provided with rope fastening hole, body vertically on, be provided with pin and pulley gear, pin and body are at grade, its front end is positioned at the indentation, there of hook portion, and pulley gear constitutes by sheave post and by the pulley that pulley spindle is arranged at its front end, and sheave post is positioned at the top of body, the back segment of pin and sheave post is the undergauge shell of column, spring is set respectively thereon, and case is installed in the middle part of body by screw, and pin and sheave post are installed on the tube chamber of case by nut.
The utility model can be provided with handgrip bullet pin on described pin, on body, be provided with and the corresponding pin-and-hole of bullet pin, and be provided with the handgrip chute on case.
The utility model has simple in structurely, easy to use, and self-locking property is good, and characteristics such as safety can ascended a height, obtain safeguard protection in the two-way process for the personnel that ascend a height.
Description of drawings:
Fig. 1-Fig. 2 is respectively front view, the left view of embodiment; Fig. 3 is the A-A cutaway view of Fig. 1; Fig. 4 is the user mode reference diagram.
Among the figure, 1, hook portion 2, pulley spindle 3, pulley 4, sheave post 5, body 6, spring 7, screw 8, nut 9, rope fastening hole 10, case 11, spring 12, handgrip bullet pin 13, pin 14, chute 15, pin-and-hole 16, breach 20, vertical rod.
The specific embodiment:
With reference to accompanying drawing; the fall arrest of ascending a height protector; comprise rigid body 5 and case 10; the front end of body is a hook portion 1; its breach is slightly larger than the diameter of special vertical rod 20, and the end of body is provided with rope fastening hole 9, body vertically on; be provided with pin 13 and pulley gear; pin and body at grade, its termination is positioned at the indentation, there of hook portion, generally; the pin front end blocks the over half of breach at least; on pin, be provided with handgrip bullet pin 12, on body; be provided with and the corresponding pin-and-hole 15 of bullet pin, and on case, be provided with handgrip chute 14.Under the normal condition, bullet pin 12 locks pin on body.Pulley gear constitutes by sheave post 4 and by the pulley 3 that pulley spindle 2 is arranged at its front end, sheave post is positioned at the top of body, the back segment of pin and sheave post is the undergauge shell of column, and overlap upper spring 11,6 respectively, case is installed in the middle part of body by screw 7, and pin and sheave post are installed on the tube chamber of case by nut 8.
Its using method and principle are:
According to field condition, to set up the cat ladder structure, and special vertical rod 20 is set, special vertical rod operated by rotary motion is right-hand the cat ladder direction, and special vertical rod 20 can be a root post of cat ladder, also can establish in addition; Before each ascend operation, an end of safety rope is lain in the personnel's of ascending a height waistband, the other end lies on the afterbody rope fastening hole 9 of anti-falling device (all there is special connecting piece at the safety rope two ends); The fall arrest protector of will ascending a height again is contained in the vertical rod 20: outside (A) drawing bullet pin handgrip 12; depress (B) and pin the upper end of pin 13; and depress (C) and pin pulley 3; the hook portion of the fall arrest protector of ascending a height is colluded in vertical rod; loosen pin; under the effect of spring 11, bullet pin reset locking pin, the fall arrest of ascending a height protector by pintle hook lock in vertical rod 20.When ascending a height, the fall arrest of will ascending a height protector places right hand top, and the fall arrest of ascending a height protector is upwards promoted by the right hand, moves up, and truckle rotates along vertical rod.Fall just in case accidentally drop, truckle is ejected by spring 6, and again because the effect of gravity, the fall arrest of ascending a height protector is stuck in the vertical rod, and this device will be hung in the personnel of ascending a height in the vertical rod, waits for other people come rescue or save oneself, and prevents because of the generation casualty accident of falling accidentally.
When unloading when ascending a height the fall arrest protector, equally outwards drawing bullet pin handgrip 12 is depressed the upper end of pin 13, and depresses pulley 3, and anti-falling device could withdraw from from vertical rod.The utility model is provided with and plays the lock fixed structure, must bimanualness just can load onto or unloads the fall arrest protector of ascending a height, and prevents to break away from the vertical rod phenomenon because of misoperation causes it, greatly the raising security performance of fall arrest protector of ascending a height.
