Abstract
A circular guide track fall protection device consists of a circular guide track (1) and a fall protector. The fall protector consists of balls (2), a fall protector body (3), a pin (4), pretension springs (5), a cam (6) and a pin sleeve (7). The fall protector encircles the circular guide track, operating conditions of the fall protection device are decided by engagement status of the cam on thefall protector and the circular guide track, namely the cam (6) acts with the rectangular surface of the circular guide track (1) under external force to generate high locking force to keep the cam ina locked state so as to prevent the human body falling, and then the higher the stress of the cam (6) is, the better the self-locking effect is. When the external force disappears, the fall protectoris unlocked to be in a freely sliding state and can slide freely on the circular guide track (1), thereby guaranteeing operators to move freely. The circular guide track (1) is fixed on a tower or abase frame via a mounting fixture, and the fall protector can be carried by the operators. The fall protection device has the advantages of reasonable structure, high intensity, fine reliability, being capable of significantly improving product using performance and effectively reducing cost, providing more effective protection for operators working at high, guaranteeing the fall protector to slide vertically along with the operators when going up or down the tower without hand interference, and further bringing more convenience for the operators working at high to operate and use.
Description
Technical field
The utility model relates to a kind of work high above the ground personal security fall-preventing protection device, relates in particular to a kind of circular guideway falling proof device.
Background technology
The anti-fall measure in high-altitude traditionally is: the staff fastens one's safety belt, and the other end hangs on the fixing point.As on power engineering high voltage line iron tower or steel tube tower, working, generally be pin nail or cat ladder by setting up on the foot-operated tower bar, the staff climbs a needed work high position and operates, and needs before the operation safety belt that ties up between waist is hung on the fixing point that ties up on the tower bar as protection safety work.But in the process of climbing up and down, safety belt will ceaselessly change with regard to the fixing point needs according to height, therefore can not get the fall arrest protection in the process that moves, in case the consequence of making a fault is with hardly imaginable.
At present, the catching device of existing various ways can effectively solve work high above the ground personnel's anti-fall problem, but also exist a lot of defectives: the scope of activities deficiency that catching device is given; The product complexity, difficulty of processing is big, and cost is higher; The catching device preponderance, when operating personnel use, very inconvenience; Some catching device needs operating personnel's manual intervention to finish smoothly when iron tower up and down, has strengthened operation easier, has increased staff's danger coefficient.
The utility model content
Deficiency at above-mentioned technology existence, the utility model provides a kind of circular guideway falling proof device, this kind guide rail falling proof device high safety rational in infrastructure, can and then slide up and down when the tower up and down in company with operating personnel, need not to intervene manually, operating personnel rest on somewhere work constantly, and catching device also can rest on the guide rail automatically, can not influence operating personnel's work.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of circular guideway falling proof device, form by circular guideway (1) and catching device, wherein catching device is again by ball (2), catching device body (3), pivot pin (4), preloading spring (5), cam (6), guide (7) is formed, its concrete feature is: catching device has surrounded circular guideway (1) entirely, cam on the catching device (6) and circular guideway (1) mated condition determine the work ruuning situation of this device, cam (6) acts on circular guideway (1) rectangular surfaces under the external force effect situation mutually being subjected to, the huge tight lock power of Chan Shenging makes cam (6) be in lockup state and avoids the human body tenesmus between the two, and the effect of the stressed big more automatic locking of cam (6) is good more.External force disappears, and the state of catching device locking is removed, and is in the state of being free to slide, and catching device can be free to slide on circular guideway (1) and guarantee operating personnel's activity freely.The utility model is simple in structure, and is easy to operate, can be carried by the operating personnel.
Described circular guideway (1) is fixed on the shaft tower by sectional fixture or on the pedestal.
Beneficial functional of the present utility model is:
1, can guarantee operating personnel up and down during tower, catching device need not manual intervention in company with sliding up and down.Make the work high above the ground personnel operation and use more convenient.。
2, operating personnel rest on somewhere work constantly, and catching device can rest on the guide rail automatically, can not influence operating personnel's work.
3, have rational in infrastructure, characteristics such as intensity is high, good reliability, simple installation

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The utility model is made up of circular guideway (1) and catching device, wherein catching device is again by ball (2), catching device body (3), pivot pin (4), preloading spring (5), cam (6), guide (7) is formed, its concrete feature is: catching device has surrounded circular guideway (1) entirely, cam on the catching device (6) and circular guideway (1) mated condition determine the work ruuning situation of this device, cam (6) acts on circular guideway (1) rectangular surfaces under the external force effect situation mutually being subjected to, the huge tight lock power of Chan Shenging makes cam (6) be in lockup state and avoids the human body tenesmus between the two, and the effect of the stressed big more automatic locking of cam (6) is good more.External force disappears, and the state of catching device locking is removed, and is in the state of being free to slide, and catching device can be free to slide on circular guideway (1) and guarantee operating personnel's activity freely.The utility model is simple in structure, and is easy to operate, can be carried by the operating personnel.
Claims (1)
1, a kind of circular guideway falling proof device, form by circular guideway (1) and catching device, wherein catching device is made up of ball (2), catching device body (3), pivot pin (4), preloading spring (5), cam (6), guide (7) again, it is characterized in that: catching device has surrounded circular guideway (1) entirely.
