Abstract
A T-shaped guide track fall protection device consists of a T-shaped guide track (1), balls (2), a fall protector body (3), a pin (4), pretension springs (5), a cam (6) and a pin sleeve (7). The bodyof the fall protection device consists of the fall protector body (3) and the T-shaped guide track (1), operation conditions of the fall protection device are decided by engaging status of the cam (6)on the fall protector body and the T-shaped guide track, namely the cam (6) acts with the rectangular surface of the T-shaped guide track (1) under external force to form high locking force to keep the cam in a 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 fallprotector is unlocked to be in a freely sliding state and can slide freely on the T-shaped guide track (1), thereby guaranteeing operators to move freely. The T-shaped guide track (1) is fixed on a tower or a base 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 fall-preventing protection device of ascending a height, and relates in particular to a kind of T shape guide rail falling proof device, is adapted at operation use on the T shape guide rail.
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 falling proof device of work high above the ground in moving process generally is along nail of the pin on the former angle steel of high tower or cat ladder, install the two rod members contour additional with shaft tower, its structure is to add two rod members that weldering polylith plate spare is made in the middle of bar and pipe, join end to end by a plurality of pairs of rod members again, be combined into two rod members that anti-falling device can move up and down usefulness.Staff's body when work is a safety belt, and the other end of safety belt ties up on the anti-falling device, and the pipe of two rod members is inserted at the exit or entrance of a clitch of anti-falling device, helps anti-falling device during climbing on the other hand, and hand steered pin nail of another or cat ladder are moved.When careless pedal is stepped on landing, with human body tenesmus pulling safety belt, cause the hook of anti-falling device to tilt, the mouth of hook just is stuck on the pipe of two rod members securely, and human body can not fallen from the high-altitude, has guaranteed personal safety.But still there is following defective in present known catching device:
(1) owing to structural reason, intensity is lower, and reliability is not high.
(2) product complexity, difficulty of processing is big, and cost is higher.
(3) catching device preponderance, when operating personnel use, very inconvenience.
(4) some product up and down needs operating personnel's manual intervention to finish smoothly during iron tower, 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 T shape guide rail falling proof device, this T shape guide rail falling proof device is 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 T shape guide rail falling proof device, be made up of T shape guide rail (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.Concrete feature is: catching device has surrounded T shape guide rail (1) entirely, cam on the catching device (6) and T shape guide rail (1) mated condition determine the work ruuning situation of this device, cam (6) acts on T shape guide rail (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 T shape guide rail (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 T shape guide rail (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 T shape guide rail (1) and catching device, catching device is by ball (2), catching device body (3), pivot pin (4), preloading spring (5), cam (6), guide (7) is formed, catching device has surrounded T shape guide rail (1) entirely, cam on the catching device (6) and T shape guide rail (1) mated condition determine the work ruuning situation of this device, cam (6) acts on T shape guide rail (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 T shape guide rail (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.
