Description

Automatically flexible pole-climbing riding boogie board

The utility model relates to a kind of automatically flexible pole-climbing riding boogie board, and particularly it can change the conventional bevel operation, makes human body parallel with electric pole, and operation under nature has reduced labour intensity.

Along with the develop rapidly of power telecommunication cause, cement electric pole replaces wooden electric pole support circuit, just popularizes all over the world as far back as the seventies, spreads all over cities and towns and rural area.Yet outside line workman operation is still being used old-fashioned or by the pole-climbing tool of old-fashioned differentiation, is being adopted traditional manual manipulation method.Workpeople not only labour intensity is big, and does not have safety guarantee, and life may be on the hazard at any time.

The domestic in recent years movable sleeve hook (as shown in Figure 1) that a kind of energy elongation occurred and shortened, this hook has two kinds of forms: a kind of is the triangle sliding sleeve; A kind of is the square sliding sleeve.The effect of two kinds of forms is identical, all is to utilize sleeve manually to move the size of regulating hook on shank, pulls adjustable range by bumping with pin during operation.Being fixedly clamped of pole-climbing relies on human weight to pressing down, and makes sliding sleeve and shank produce torsion and realizes.This movable hook that is formed by fixed differentiation has had progress than former generation instrument, but has still existed inconvenient operation, and has brought new life-threatening safety related technical problems thus.During operation, back is set foot on the low fixed pivot of safety coefficient, and one step of back will cross over the front, uses pin to collide very hardly and pulls sleeve and regulate size.Regulate size on all pin being contracted at every turn, very painstaking during operation.And, because coupling sleeve skids, very easily cause operator's life security accident.Various reasons shows: it is less that one, coupling sleeve relies on human body weight pressure generation torsion, because any insurance institution is not set, skids so very easily cause; Two, coupling sleeve can not soak, and during operation was carried out, in case of raining suddenly, coupling sleeve was got wet and also can be skidded; Three, coupling sleeve can not be made dirty, also causes skidding if any greasy filth.The use of this instrument is not only influencing the outside line work quality in varying degrees, and the also difficult generation of avoiding accident of careful operation.

The purpose of this utility model is just in order to solve weak point of the prior art, and proposed a kind of automatically flexible pole-climbing riding boogie board, is pole-climbing tool of new generation.It can not only flexiblely automatically, synchronous up and down clamp, and steps on expediently and climbs isometrical bar or non-isometrical bar, and improved safety coefficient, has reduced labour intensity.

The purpose of this utility model is achieved in that

Automatically flexible pole-climbing riding boogie board, by riding boogie board, compositions such as pedal hook, a ratchet bar has been adorned at the straight-bar position of pedal hook riveting side by side, a pedal axis is equipped with in the riding boogie board below, on the axle three whole rivetings of coupling sleeve are housed and become an integral body, rocking arm sheet of riding boogie board front welding, on the anterior spindle nose of pedal axis a torque spring is housed, pedal hook, riding boogie board and ratchet all are to be unified into by the splicing sleeve assembling to be one, one of torque spring on the pedal axis is fixed on the splicing sleeve, the other end active force is equipped with a tension spring in the bottom of riding boogie board on the ratchet palm, ratchet two-way all can with the ratchet bar Elastic Contact.

The utility model has 4 width of cloth accompanying drawings, and wherein Fig. 2 is a most preferred embodiment of the present utility model, also can make the accompanying drawing of specification digest.

Fig. 1, be old-fashioned telescopic pole-climbing riding boogie board structural map;

Fig. 2 is structural map of the present utility model;

Fig. 3, be A-A cutaway view of the present utility model;

Fig. 4, be arrowhead revolved view of the present utility model;

The utility model compared with prior art has following advantage: the utility model can isometrical or The realization automatic telescopic is stepped on and is climbed on the non-equal-diameter pole, synchronous clamping, and easily operation, and improve Safety coefficient, reduced labour intensity.

Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described further.

Most preferred embodiment of the present utility model as shown in Figure 2, flexible automatically pole-climbing riding boogie board is made up of riding boogie board, pedal hook etc., a ratchet bar 6 has been adorned at the straight-bar position of pedal hook 1 riveting side by side, gib head has welded two block plates 13, and has adorned two sheet rubbers 5.A sheet rubber 5 is adorned in riding boogie board 9 sides, and a pedal axis 2 is equipped with in the below, on the axle the 3 whole rivetings of three coupling sleeves is housed and becomes an integral body.Welding rocking arm sheet 7 in riding boogie board 9 fronts is equipped with a torque spring 4 on the pedal axis 2 anterior spindle noses.Pedal hook 1, riding boogie board 9 and ratchet 10 all are to be unified into by splicing sleeve 8 assemblings to be one, and one of the torque spring 4 on the pedal axis 2 is fixed on the splicing sleeve 8, and the other end active force is in the bottom of riding boogie board 9.Under the effect of torsion, often make pedal hook and riding boogie board be in the position of 40 ° of gradients.A tension spring 11 is housed on the ratchet palm, make ratchet 10 two-way all can with ratchet bar 6 Elastic Contact.

During pole-climbing, riding boogie board 9 is lifted by torque spring 4 vertically, with 8 one-tenth 40 ° of splicing sleeves, ratchet 10 is pushed backward lifting position, at this moment steps on riding boogie board 9 and is about 20 °, and the anti-skidding insurance tooth 14 of riding boogie board 9 bottoms just falls into the teeth groove of ratchet bar 6.When stepping on, two rocking arm sheets 7 are also axially swung 20 ° in the back with riding boogie board 9, and the pin hook that makes ratchet 10 drive ratchet bars 6 dwindles 10 millimeters, and at this moment riding boogie board 9 one is stressed, and hook is clamped again, makes it to slide.When rising, as long as one carries pin, the rear portion of riding boogie board 9 is under the effect of torque spring 4, automatically lift again, at this moment the rubber 5 that is fixed on riding boogie board 9 sides down rotates the electric pole that gets loose, two rocking arm sheets 7 are swung forward, drive ratchet 10 and move a tooth forward, and the automatic deflation of the folder hook after moving is dwindled naturally with the back electric pole that rises and remained synchronous size.By this circulation, promptly realized automatic deflation pole-climbing action one by one.This device design is whenever advanced a tooth and can be gone up one meter, accelerates the rate of climb as need, steps on several steps just can reach more at every turn; During lower beam, the handle on the sour jujube chi 10 is pushed down position forward, do opposite motion as above-mentioned action with hand.Whenever step on a pin, the pin hook is elongation automatically just.As increasing decrease speed, step on several pin more at every turn and can realize.
