Abstract
The invention discloses a boarding ladder, relates to a ladder, and solves the technical problem that the conventional boarding ladder is large in occupied space, heavy in weight and high in cost. A ladder body consists of handrails, square steel tubes, kick pedals, angle steel and a shaft sleeve; the shaft sleeve is connected with an output shaft of a swing oil cylinder; the swing oil cylinder is arranged on a fixing frame; the fixing frame is arranged on the side of equipment; and a locking device consisting of a proximity switch, a locking oil cylinder, a locking pin and a locking frame is arranged at the vertical position of the ladder on the upper part of the equipment. The boarding ladder is used for mechanical equipment and has the advantages of small occupied space, simple structure and low manufacturing cost.
Description
Technical field
The present invention relates to ladder, the airstair of using always on particularly a kind of mechanical equipment.
Background technology
With ground the equipment of relative motion is arranged, or to space requirement than higher fixed equipment, when operating mechanism is overhead higher, need to use ladder.Fixed type ladder on the go damages or easy and miscellaneous equipment collision easily, generally adopts less.Though rope ladder and cat ladder are simple in structure, conserve space, weight is lighter, for the place of frequent use, uses relatively effort.
What use always on the equipment at present is the ladder that oil cylinder or cylinder promote.Oil cylinder, body, ladder become the triangle hinged relationship, the angle of the folding and unfolding decision ladder of oil cylinder.Ladder puts down before boarding, and lifts after boarding.The anchor shaft of such ladder is parallel with the ladder rotating vector.Generally be positioned at equipment left side or right side outside face, the width of ladder makes that the width of equipment is also corresponding have been increased, and existing ladder takes up room greatly.In addition, also need increase the device of fixed oil cylinder on the equipment, and walk on stage etc., weight of equipment increased.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art.A kind of airstair is provided, solves existing ladder and take up room greatly, quality is heavy, the technical matters that cost is higher.
The present invention realizes through following technical scheme:
A kind of airstair; Comprise: the ladder body; It is characterized in that: said ladder body is made up of railing, square steel tube, tap-tap plate, angle steel and axle sleeve, and said axle sleeve is connected with the output shaft of swing-type cylinder through flat key, and the axle head of said output shaft is through baffle plate and bolted; Said swing-type cylinder is installed on the steel plate of fixed mount; Steel plate and vertical plane angle excursion A, said output shaft is vertical with said steel plate, the angled A of said output shaft and horizontal surface; The plane of ladder body and the angled A of said output shaft, said square steel tube and vertical plane are angle 2A; Said fixed mount is installed on the side of equipment (body); The top of equipment (body), be positioned at ladder and arrive the vertical position place; Be fixed with the latching device of forming by near switch, locking cylinder, locking pin and locking frame; Saidly be installed in successively on the said locking frame near switch, locking cylinder, locking pin, said locking frame is fixed on the equipment (body).
The present invention compared with prior art accomplishes the back ladder and holds up owing to board, and nearer with the equipment lateral distance, so it is little to take up room, locking device structure only contains near switch, locking cylinder, locking pin, and is simple in structure, low cost of manufacture.
Description of drawings
Fig. 1 is structural representation of the present invention (front view),
Fig. 2 is structural representation of the present invention (lateral plan),
Fig. 3 is structural representation of the present invention (an A-A section-drawing),
Fig. 4 is a ladder main body structure scheme drawing among the present invention.
The present invention is elaborated through preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
Like Fig. 1,2,3, shown in 4; A kind of airstair; Comprise: ladder body 1, said ladder body 1 is made up of railing 1-1, square steel tube 1-2, tap-tap plate 1-3, angle steel 1-4 and axle sleeve 1-5, and said axle sleeve 1-5 is connected with the output shaft 3-1 of swing-type cylinder 3 through flat key; The axle head of said output shaft 3-1 is fastening through baffle plate 5 and bolt 6, prevents that ladder from coming off from axle head; Said swing-type cylinder 3 is installed on the steel plate 2-1 of fixed mount 2; Steel plate 2-1 and vertical plane angle excursion A; Said output shaft 3-1 is vertical with said steel plate 2-1, said output shaft 3-1 and the angled A of horizontal surface, the plane of ladder body 1 and the angled A of said output shaft 3-1; Said square steel tube 1-2 and vertical plane are angle 2A, and this makes the people laborsaving when boarding through ladder; Said fixed mount 2 is installed on the side of equipment (body); The top of equipment (body), be positioned at ladder and arrive the vertical position place; Be fixed with the latching device of forming by near switch 4, locking cylinder 7, locking pin 8 and locking frame 9; Saidly be installed in successively on the said locking frame 9 near switch 4, locking cylinder 7, locking pin 8, said locking frame 9 is fixed on the equipment (body).
Working process of the present invention:
Fig. 1,2 are depicted as the state when boarding; Fig. 3 top dotted line is that the state after the locking is holded up in board completion, ladder.
At the state of boarding, ladder is in the bottom, is angle 2A with vertical plane.
When ladder need be locked, arrive output axisymmetric position (dotted portion) behind the ladder Rotate 180 degree, the angle A of the angle A of ladder and output shaft and output shaft and horizontal surface is cancelled out each other, and ladder is vertical in ground after along with output shaft Rotate 180 degree.
In the time of ladder rotation approach locking device desired location (vertical position); Moving of latching device near switch 4; The oil cylinder 7 of locking dress stretches out; The locking pin 8 that promotes to cooperate puts in the hole of ladder square steel tube, makes ladder in equipment moving, can keep motionless, has reached the purpose of locking ladder.
When getting off on the needs slave unit, the locking cylinder action, locking pin is extracted out, oscillating oil cylinder action then, ladder rotates to the bottom surface, thereby can board.
