Specific implementation mode
It is described in detail the particular content of the utility model with reference to the accompanying drawings and examples.
As shown in Fig. 1, the utility model provides a kind of rock drill step ladder, including：
Accommodating chamber 1, accommodating chamber 1 are set to below rock drill operating room, and accommodating chamber 1 is from rock drill side to operating room side
To the groove body of extension, opening both sides are hinged sealing plate 6, and the free end of two pieces of sealing plates 6 is equipped with the lock (figure being used cooperatively
On be not drawn into).
Mounting plate 2, mounting plate 2 are fixed on inside the accommodating chamber 1, and two guide grooves 3 are arranged in parallel on mounting plate 2, peace
The width of loading board 2 is less than 1 width of accommodating chamber, sets that there are two the fixations that one end protrudes from 2 top surface of mounting plate on the end face of mounting plate 2
Piece 10, the fixinig plate 10 are equipped with the first mounting hole, gag lever post 9 are equipped between two the first mounting holes.
Terraced body, terraced body include two side plates 4 and several pedals 5, and two side plates 4 are arranged in parallel, and 4 bottom of the side plate is equipped with
With 4 integrally formed sliding block 41 of side plate, 4 middle part of side plate is equipped with the strip through-hole 42 passed through for the gag lever post 9, several pedals 5
It is in turn secured between two side plates 4, junction is equipped with angle regulator 11, and the ladder body passes through sliding block 41 and the peace
2 slidable connection of loading board, and be rotatably connected by the strip through-hole 42 and the gag lever post 9.
As shown in Fig. 2, further include stepper motor that output end is connected with the gag lever post 9,9 both ends of gag lever post set is with teeth
Wheel 12, the strip through-hole 42 is interior to be equipped with the rack 13 being meshed with the gear 12.When it is desired to be used, stepper motor is positive
Rotation, gear 12 drives the strip through-hole 42 on terraced body to move in a straight line, can be by when terraced body end reaches 1 opening of accommodating chamber
It is moved downward in the effect of gravity, when terraced body is all fallen, stepper motor break-off.After people comes into driver's cabin, stepping
Motor rotates backward, and terraced body is taken in along strip through-hole 42 and guide groove 3 inside accommodating chamber 1, then by the work people on ground
Member locks lock.
Since the position of the first mounting hole is higher than mounting plate 2, and the width of mounting plate 2 is less than the width of accommodating chamber 1, therefore
Terraced body can be had a certain degree by the support force of 1 side of accommodating chamber with ground shape after falling, convenient for climbing.Rock drill works
The normal uneven of workplace ground, if the high side in ground side stopped is low, terraced body can change with ground angulation.Ladder
The variation of body and ground angulation will not cause cat ladder obstacle because usually this variation will not very greatly, but if pedal 5 and
The angle of side plate 4 is fixed, then pedal 5 and the angle on ground can also change, the influence climbing difficulty and peace of this very big degree of meeting
Whole step.If pedal 5 tilts down, people, which walks up, to be tilted upwards to downslide, pedal 5, then can very be not easy to people and step on
Up, it and may fall, be absolutely unsafe from the gap location of two pedals 5.Therefore, it is necessary between pedal 5 and side plate 4
Angle is adjusted.
As shown in attached drawing 3 and attached drawing 4,11 one end of the angle regulator connects the pedal 5, and the other end passes through setting
It is stretched out outside the side plate 4 in the second mounting hole on side plate 4, specifically includes and be fixedly connected with 5 side of the pedal and hollow
The first rotation axis 141, several first openings 151 are distributed uniformly and circumferentially in the first rotation axis 141, further include being sleeved on the
The second rotation axis 142 inside one rotation axis 141, the second rotation axis 142 are equipped with and the first opening 151 quantity identical second
Opening 152, hinged one end is equipped with the rotating member 16 of fillet in second opening 152, is equipped in second mounting hole and institute
State that 16 quantity of rotating member is identical and shape matches sawtooth 19 so that when pressing the second rotation axis 142 inwards, the circle of rotating member 16
Angle 152 and first opening 151 of protruding second opening by the resistance of 141 bottom surface of the first rotation axis, and be clamped on described
The limit to pedal 5 is realized in sawtooth 19, when extracting the second rotation axis 142 outward, rotating member 16 by the first opening 151 resistance
Power and retract, release locking to pedal 5, the first rotation axis 141 of rotation is adjustable angle between the pedal 5 and side plate 4
Degree.
It, will to be disconnected with the first rotation axis 141 when the second rotation axis 142 being avoided to be transferred to out of first rotation axis 141
The free end of first rotation axis 141 is closed, and clicking section 17 is equipped in the second rotation axis 142, in first rotation axis 141
Equipped with the third opening 153 passed through for the clicking section 17, it is equipped between first rotation axis, 141 and second rotation axis 142
Flexible limit circle 18, for keeping concentric between the first rotation axis 141 and the second rotation axis 142.It therefore, can be by stirring
Realize the propulsion and pull-out to rotation axis 142 in portion 17.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the right of the utility model.
