Abstract

An automatic telescopic climber which can adapt to the climbing action of people. The device can realize the climbing of a human body on columnar equipment, in particular to a convenient, rapid and safe climbing device for climbing telegraph poles and the like. It is composed of a shifting fork, a mandrel, a shaft sleeve and a jaw. During climbing, the target climbing height can be achieved only by repeating the action cycle of 'loosening, stepping, clamping and foot changing' of the two climbers.

Description

Automatically flexible climbers

The utility model relates to the device of a kind of climbing cylindricality equipment (as electric pole).

At present, known climbing device is single deck tape-recorder pawl climbers, the every leg of operator is tied up climbers, whenever step on a step during climbing, all need with hand outwards, climbers of push-and-pull inwards, can adapt to required angle, so just give and climb operation and bring many inconvenience, inefficiency can also jeopardize personal safety sometimes.In addition, existing climbers complex structure benzene is heavy.

The purpose of this utility model provides a kind of automatically flexible climbers, makes the climbing operation as though walking upon flat ground, and both convenient, safety can be raised the efficiency 2-3 again doubly.

The purpose of this utility model is achieved in that automatically flexible climbers are by pedal, fixedly belt, axle, axle sleeve, spring, fork and claw are formed, have oblong shaped orifices on the pedal, fixedly belt penetrates in the aperture, axle one end has flange, and spring is inserted in axle and is close to flange, and two forks are separately fixed on the end face of pedal, be processed with sawtooth on the face of fork, claw is a semicircular arc, and the arc of two claws is symmetrical, and claw is connected axle with fork with hinge.

Climb the every leg of operator and all tie up automatically flexible climbers, make that pin is flat to be stepped on pedal, pass punch holes on the pedal with belt again, and the fastening instep is prepared to climb.Two claws of free state are the form of unclamping, be inserted in the cylinder of climbing when two claws after, the toothed surface of shift fork at first contacts with cylinder, under the effect of human body gravity, climbs the toothed surface of cylinder pushing shift fork.Make the afterbody pushing axle of shift fork like this, simultaneously, the spring compression, axle continues to press, and pressure is pressed onto the tail end of claw by flange, the spring of axle always, claw is swung to close cylinder direction around the intersection point of axle axis and claw center line, formed the result that two claws clamp cylinders.When two climbers all clamp cylinder and need upwards climb, only need human body weight is concentrated on the leg, another non-loaded climbers were laid down pressure (unloading) because it is pressed between shift fork on the cylinder and cylinder originally, spring also just freely opens, make the axle flange no longer compress the claw tail end, and by the opening of spring, pushing tow claw tail end makes claw recover releasing orientation position before stressed.Two claws unclamp cylinder, get ready for upwards climbing the first step.The climbers that climbing the operator only needs to unclamp cylinder are upwards stepped on a step, make shift fork come on the cylinder again, simultaneously, human body weight is shifted a part to be given on the climbers that newly step, the shift fork of these climbers is pressurized again, drive axle, spring and claw again, make two claws clamp cylinder again, so just finished the first step of climbing.Human body weight is moved on on the climbers of new chucking fully, another climbers can be got ready for stepping for second step owing to cylinder is unclamped in unloading equally again.So circulation, two legs of substituting repeatedly, make double-legged sprocket wheel stream repeat " take a step-move-pressured cylinder one axle of human body weight-shift fork push away claw swing a pair of claw clamp cylinder one in addition 1 climbers unloading preparation take a step-take a step again " the climbing operation procedure.When climbing the object height of operation, human body weight to be shared on both feet, two climbers clamp simultaneously, make human body support stably, be fixed on and carry out operation on the cylinder.Automatically flexible climbers of the present utility model, freely easy to use, the operator climbs action as long as press nature, need not look after climbers, both can be engaged in the climbing operation smoothly.Operator when falling the pin, want pin supporting naturally, a pin lifts takes a step.The utility model realizes climbing purpose according to this essential of exercise.

Owing to adopted such scheme, when the operator is climbed action very freely, fast, climbers simple in structure, light and handy is easy to make and wear.Owing to be two jack catchs types, more increased the clamping effect of climbers, so personal safety is ensured.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

Among the figure 1, pedal 2, wear hole (belt omission) 3, axle 4, axle sleeve 5, spring 6, shift fork 7, the claw of belt

Automatically flexible climbers among Fig. 1 are the shapes under its nature, i.e. the form in face of the clamping column not.Two claws (7) of climbers are the both sides that are installed in of symmetry, and each claw (7) is connecting axle (3), spring (5) and shift fork (6) separately, form separately power and action transfer unit.In the axle sleeve (4) that two unit all are fixed on and pedal (1) fuses, axle (3) can move axially in axle sleeve (4).After the pedal (1) that operator's two legs are placed on two climbers is respectively gone up, pass punch holes (2) on the pedal (1) pin and pedal bundle jail with belt.Bipod drives climbers and packs into cylinder then, earlier with moving on to overhead suitably height on the leg, human body weight is added in (steady and sure living on the face) on the climbers of lifting, the shift fork of these climbers (6) contact cylinder, produce pressure, this pressure is passed to axle (3) through the afterbody of shift fork (6), axle (3) is moved axially and push spring (5), the flange of axle (3) directly pushes the tail end of claw (7) by spring (5) compression simultaneously, because of claw (7) is that hinge is connected with axle (3), like this claw (7) the thrust of axle (3) next around axle (3) axial line and the intersection point of claw (7) center line make garden week pendulum, clamp the friction that cylinder produces up to two claws (7), be enough to support human body weight and when constituting the dynamic balance system, promptly finished the first step of climbing.Move another leg and climbers thereof again, the transmittance process of same principle and power.Second step that makes these climbers clamp cylinder once more and finish climbing.Climb if continue, as long as body weight is bearing in that leg that moves on non-to be buckled, the climbers that move are because of laying down load, there has not been pressure between its shift fork (6) and cylinder, two claws (7) are all flicked by the spring of unit (5) separately, two claws (7) unclamp with cylinder, get ready for stepping next step.The supporting-point of so continuous transfer human body weight moves the relative position of left and right climbers to cylinder in succession, repeats " unclamping a clamping one change of feet of taking a step " actuation cycle of two climbers, makes the operator continue to climb, until object height.

Automatically flexible climbers of the present utility model are applicable to the climbing operation of existing all size electric pole, simple in structure simultaneously, be suitable for manufacturing, cost low, easy to use, reduced working strength of workers, guaranteed safety work.
