Description

A kind of ship activity step ladder
Technical field
The present invention relates to a kind of ladders, more specifically, it relates to a kind of ship activity step ladder.
Background technique
Currently, be typically equipped with step ladder on ship, can be used for going on board or on ship different height position up and down It advances, step ladder is generally positioned at the two sides of ship when not used, but since step ladder is than cumbersome, can many times interfere ship The normal operation of other equipment on oceangoing ship.For step ladder in use, since sea wind and wave are larger on ship, step ladder can be with ship It jolts together inclination, process of ascending a height or stands that there are biggish security risks in operation on step ladder.
Summary of the invention
The present invention overcomes step ladders than cumbersome, and occupied space is big, and there are biggish safety in step ladder use process The deficiency of hidden danger provides a kind of ship activity step ladder, it is lighter, occupies little space, double in step ladder use process Foot is not easy the treadle that slips away, and use process is safe and reliable.
In order to solve the above-mentioned technical problem, the invention adopts the following technical scheme: a kind of ship activity step ladder, including a left side Vertical plate, column, right risers, upper attachment beam, lower attachment beam, column are in U-shape structure, and left risers, right risers are towards the side of column Be equipped with guide groove of ascending a height on upper and column left outside side, right lateral surface, two on column ascend a height guide groove respectively with left risers It is symmetrical arranged with the guide groove of ascending a height in right risers, guide groove of ascending a height includes rising guide groove and decline guide groove, rises guide groove upper and lower ends It is connected to respectively with the upper and lower ends of decline guide groove, rises guide groove and be spliced by several in the guide section head and the tail of " 7 " character form structure, It is vertically arranged to decline guide groove, lead-over groove is connected between guide section upper end and decline guide groove, guide section upper end lower wall is equipped with fixed Position groove, is all connected with a treadle between left risers and column and between right risers and column, treadle is equipped with pin holes, treadle Both ends are slidably inserted into two respectively and ascend a height in guide groove;Decline guide groove in several support columns are installed, between left risers and column with And inverted U-shaped elevating lever is mounted between right risers and column, left risers, column, be respectively connected in right risers several with The mounting box that support column is arranged in a one-to-one correspondence, connects reset spring between support column rear end and mounting box, support column front end is close Decline guide groove aperture position, support column rear end is equipped with guide pad, and guide pad is equipped with inclined guide surface, on elevating lever and is oriented to Block is correspondingly provided with pushing block, and pushing block is equipped with the promotion face being obliquely installed, and promotion face is bonded with guide surface and can push support Column is mobile to reset spring direction, installs return spring between elevating lever upper end and upper attachment beam, in left risers and right risers Several swing arms are hinged with, swing arm one end is equipped with connection sliding slot, connects slidable connection pin shaft in sliding slot, pin shaft, which is fastenedly connected, to be risen It drops on bar.
When being ascended a height using step ladder, two feet are inserted respectively into the pin holes on two treadles, and a foot is lifted up, separately One foot drives treadle both ends rising upward sliding in guide groove, reaches and rise determining for guide groove guide section upper end as support leg Position groove location, treadle both ends support in positioning groove;Then it changes a foot to be lifted up, while changing a foot as support Foot drives another treadle both ends rising upward sliding in guide groove, reaches the positioning groove position for rising guide groove guide section upper end, Treadle both ends support in positioning groove.Such two feet, which are alternately lifted up, drives treadle to move up, and realizes movement of ascending a height.
When needing to get off from step ladder, foot-up slides into treadle in decline guide groove after lead-over groove, a hand Swing arm is pulled up, swing arm drives elevating lever to move down, and the pushing block on elevating lever pushes out guide pad, to make to prop up Dagger is mobile to reset spring direction, and a corresponding treadle moves down certain distance, then decontrols swing arm, in return bullet Spring acts on lower elevating lever return, and the support column return under action of reset spring, treadle slide downward supports to next at this time On dagger;Then it lifts another foot to slide into treadle after lead-over groove in decline guide groove, another hand pulls up separately The swing arm of side, swing arm drive another elevating lever to move down, and the pushing block on elevating lever pushes out guide pad, to make Support column is mobile to reset spring direction, and a corresponding treadle moves down certain distance, swing arm then decontroled, in return Spring acts on lower elevating lever return, and the support column return under action of reset spring, treadle slide downward supports to next at this time On support column.Such two hand blocked operations, two foot blocked operations get off from step ladder.
Step ladder is only provided with two treadles, and compared with common step ladder, treadle quantity is substantially reduced, and makes step ladder more Light, when placement, is conducive to reduce occupied space, avoids interfering phenomenon with equipment other on ship.And step ladder is dismantled It is convenient to assemble, and places and occupies little space after disassembly.Whole process both feet are inserted into pin holes, are not easy the treadle that slips away, safety Reliably, even if step ladder run-off the straight, both feet will not slip away treadle.This ship activity step ladder is lighter, occupies empty Between it is small, both feet are not easy the treadle that slips away in step ladder use process, and use process is safe and reliable.
Preferably, the height of lead-over groove is higher than guide section upper end level.This structure setting makes pedal during ascending a height It will not slide into lead-over groove easily.
Preferably, rising guide groove lower end and decline guide groove lower end link position equipped with positioning groove.Positioning groove is set It sets and is positioned reliably when treadle being made to be in extreme lower position.
Preferably, the upper and lower ends of left risers, column, right risers are equipped with the locking slot of arc.When step ladder is fixed, Bolt is fastened on ship after passing through locking slot, and the setting of locking slot greatly facilitates the fastening of step ladder.
Preferably, elevating lever upper end is equipped with connecting column, upper attachment beam is equipped with connector sleeve, and return spring upper end is sleeved on It connects on column outer wall, return spring lower end is sleeved in connector sleeve.The setting of connecting column and connector sleeve greatly facilitates return bullet The installation of spring.
Preferably, being equipped with installation groove with reset spring link position on support column, it is recessed that reset spring is connected to installation In slot.The installation of reset spring is convenient in the setting of installation groove.
Preferably, treadle includes elliptoid footrest ring, the linking arm being connected at left and right sides of footrest ring, connection Arm end is connected in guide groove of ascending a height, and the annular distance of footrest ring is as pin holes.The treadle setting of this structure makes both feet be not easy to slide From footrest ring.
Preferably, elevating lever runs through mounting box, mounting box upper and lower ends are equipped with location hole, and elevating lever and location hole are suitable With plug-in.Elevating lever runs through mounting box, and location hole plays good positioning action to elevating lever, prevents elevating lever horizontal To sliding.
Compared with prior art, it the beneficial effects of the present invention are: ship activity step ladder is lighter, occupies little space, Both feet are not easy the treadle that slips away in step ladder use process, and use process is safe and reliable.
