Technical field
The invention belongs to a kind of fall arrest lifesaving appliance, specifically, more particularly to it is a kind of for the anti-fall of pole tower operation
Device.
Background technology
According to the requirement of power construction safety regulation for operations, in transmission line of electricity rod-rising tower operation, it is necessary to take effective
Safety precautions, avoids occurring the accident of staff's high falling.The operation principle of existing anti-fall device is：Working
When tenesmus situation occur in personnel, brake plate contacts realization braking with rail friction.But the situation of guide rail surface icing in the winter time
Under, the friction brake force of brake plate and guide rail greatly reduces, and staff is difficult to play effective braking protective effect, in addition
The reliability of brake plate is also extremely important, and brake plate is also possible to fatigue fracture or brake failure occur at some in special circumstances
Situation, cause that there are larger security risk.Therefore, there is an urgent need for one kind in the prior art to have the function of that dual anti-falling protection is used for
The anti-fall device of pole tower operation.
The content of the invention
It is an object of the present invention to provide a kind of anti-fall device for pole tower operation, is used for shaft tower work in the prior art to overcome
The anti-fall device of industry only has a defects of weight anti-drop function causes its safety and reliability not high.
The present invention is realized using following technical scheme：
Anti-fall device of the present invention for pole tower operation, including guide rail and the catching device that is flexibly connected with guide rail,
The catching device includes connecting seat and brake plate, and the brake plate is hinged by hinge shaft and connecting seat, and the connecting seat is equipped with
Guide rail straight slot, the connecting seat are sleeved on guide rail by guide rail straight slot；The guide rail is equipped with anti-fall hook, the connecting seat
Side plate is equipped with arc-shaped hole track low after height before one section, and load-bearing latch is provided with the arc-shaped hole track；The system
The afterbody of movable plate is with holes equipped with safety, and when the brake plate afterbody pulls down, its head is contacted with guide pass.
The hinge shaft is equipped with torque spring.
The head of the brake plate is in cam-like.
The guide rail surface is coated with anti-icing paint.
Spacing between two anti-fall hooks is not more than 1m.
The both ends of the load-bearing latch are cased with gasket respectively, and the both ends of the load-bearing latch are respectively equipped with through hole, in through hole
The semicircle fixing card of installation.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention possesses dual anti-falling protection function, in the case where friction catch fails, moreover it is possible to by being linked up with guide rail
Realize that locking is anti-fall, therefore the anti-fall device that in extreme climate environments such as ice and snow, greatly strengthen for pole tower operation can be used
Safety and reliability.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, the anti-fall device of the present invention for pole tower operation, including guide rail 1 and catching device 3,
Catching device 3 includes connecting seat 7 and brake plate 4, and brake plate 4 is hinged by hinge shaft 6 and connecting seat 7, and connecting seat 7 leads to equipped with guide rail
Groove (not shown), connecting seat 7 are actively set on guide rail 1 by guide rail straight slot；Guide rail 1 is equipped with anti-fall hook 2, connecting seat
7 side plate is equipped with arc-shaped hole track 9 low after height before one section, and load-bearing latch 8, load-bearing are provided with arc-shaped hole track 9
Latch 8 can be free to slide in arc-shaped hole track 9；The afterbody of brake plate 4 is equipped with safety with holes 5, and safety with holes 5 is used to connect
The safety belt fixed with human body, when human body drops, and 4 afterbody of brake plate pulls down, its head contacts realization friction system with 1 face of guide rail
Dynamic, the head of brake plate 4 is preferably in cam-like.
The situation of anti-fall device of the present invention brake fade under ice and snow weather condition occurs in order to prevent, the surface of guide rail 1
Coated with anti-icing paint, it can effectively suppress water and freeze on 1 surface of guide rail, and adhesive force of the ice on 1 surface of guide rail is very poor,
It is easy to come off under external force.
Anti-fall hook 2 catches on load-bearing in the case of being brake plate 4 and 1 brake fade of guide rail in the failure of the first weight anti-falling protection
Latch 8, and then play the role of the second weight anti-falling protection, in order to prevent to anti-fall hook in the case of the first weight anti-falling protection failure
Impact force is excessive caused by 2, and the spacing between two anti-fall hooks 2 is not more than 1m, while considers to reduce manufacture cost and raising
The convenience of operation, two anti-fall spacing linked up between 2 are also unsuitable too small.
As shown in figure 4, the both ends of load-bearing latch 8 are cased with gasket 12 respectively, the both ends of the load-bearing latch 8 are respectively equipped with logical
Hole, the semicircle fixing card 11 of the interior installation of through hole；Torque spring 10 is preferably provided on hinge shaft 6, torque spring 10 is used to keep braking
The state that plate 4 is upturned under normal circumstances.
The use process of the present invention：During staff's normal operation, safety belt and safety with holes 5 are connected firmly, worked
In personnel's climbing, catching device 3 rises along guide rail 1 with personnel, and 4 head of brake plate is separated with 1 surface of guide rail, once
Personnel fall, and under external force, rapidly to lower swing, 4 head cam of brake plate rotates 4 afterbody of brake plate, with 1 surface of guide rail
Contact, and then be stuck on guide rail 1, human body is no longer fallen downwards；When brake plate 4 and 1 brake fade of guide rail, bearing pin
8 slide the bottom to arc-shaped hole track 9 under the effect of gravity, and then hang on anti-fall hook 2, under preventing human body further
Pendant.
