Detailed description of the invention
In order to understand the ladder hanging rack structure according to the present invention program better, be further elaborated explanation below in conjunction with the preferred embodiment of accompanying drawing to ladder hanging rack structure of the present invention.
As Figure 1-4, ladder hanging rack structure provided by the present invention, comprise fixed beam 1, hanger bearing 2, hanger bearing 2 is fixed on fixed beam 1, fixed beam 1 arranges two hanging points, hanging point place is provided with hanger bearing 2, hanger bearing 2 is the hollow bearing of monaural, the earhole interference fit of hanger bearing 2 is provided with bearing pin a3, bearing pin b4, one end that bearing pin b4 differs from limit dais is provided with Quick-release pin mounting hole, and Quick-release pin 5 and Quick-release pin mounting hole are connected and are linked up with on the 6 bearing pin b4 be limited between hanger bearing 2 and Quick-release pin 5 by ladder.Ladder hook 6 to be stuck in bearing pin a3, bearing pin b4 on and to be pinned by anticreep dead bolt 7, and the homonymy that 6 are arranged at two hanger bearings 2 linked up with by ladder.The base plate of hanger bearing 2 is provided with and fixed orifice is installed and by bolt, hanger bearing 2 is fixed on fixed beam 1.
The ladder be equipped with hanger bearing 2 links up with 6 for hollow structure, ladder hook 6 is fixed on ladder side bar 8, link up with ladder that 6 lock bearing pin a3, bearing pin b4 is provided with anticreep dead bolt 7, anticreep dead bolt 7 and ladder links up with 6 and are fixed on ladder by pivot pin and links up with on 6, pivot pin are provided with return spring and make ladder hook 6 and anticreep dead bolt 7 be in closure state.
Hanger bearing 2 base plate is bolted to connection on fixed beam 1, and monaural and base plate are formed in one structure, have ensured the Joint strenght between monaural and base plate, improves the safety of device, stability.Match with the earhole of the monaural structure of hanger bearing 2 and be provided with bearing pin a3, bearing pin b4, the similar of bearing pin a3 and bearing pin b4, difference is, the bar portion of bearing pin b4 is than the bar minister of bearing pin a3, and the part grown is for arranging Quick-release pin mounting hole.Quick-release pin 5 and the Quick-release pin mounting hole interference fit on bearing pin b4.Two ladders hook 6 on ladder to be buckled on bearing pin a3 and bearing pin b4 and by anticreep dead bolt 7, ladder to be linked up with 6 and pins.Ladder hook 6 carries out spacing with Quick-release pin 5 by bearing pin b4, prevents ladder from linking up with 6 along bearing pin axial motion, skid off bearing pin.
In concrete use procedure, fixed beam 1 arranging two hanging points, is the distance on ladder between two ladder hooks 6 in the hanging point place distance arranged on hanger bearing 2, two hanger bearing 2 between monaural structure.The structural earhole of monaural on hanger bearing 2 is respectively arranged with bearing pin a3, bearing pin b4 interference fit with it, hanger bearing 2 is hollow structure, hollow structure can ensure that shearing and moment of flexure are effectively transmitted, can ensure that again moment of torsion effectively transmits, structure efficiency is higher and can alleviate integrally-built quality.
The length in the bar portion of bearing pin a3, bearing pin b4 is all greater than monaural structure and ladder on hanger bearing 2 and links up with the thickness sum of 6, and in addition, the length of bearing pin b4 is larger than the length of bearing pin a3, and the part grown is for installing the Quick-release pin mounting hole set by Quick-release pin 5.By the locking of anticreep dead bolt 7 on ladder hook 6 and the restriction of bearing pin b4, ladder hook 6 is fixed on bearing pin a3 and bearing pin b4, and can not come off hanger bearing 2.
When hanging rack structure provided by the invention installs ladder, only need two ladder hooks 6 be buckled on bearing pin a3 and bearing pin b4 respectively, then in the Quick-release pin mounting hole of bearing pin b4, plug Quick-release pin 5.The anticreep dead bolt 7 that ladder hook 6 is arranged links up with 6 one-tenth closure states with ladder under ladder idle state; When being hung on hanger bearing 2 by ladder hook 6, anticreep dead bolt 7 power of being squeezed can open opening, and when bearing pin is stuck in the inside of ladder hook 6 completely, the application force that anticreep dead bolt 7 is subject to spring gets back to initial position again.
When hanging rack structure provided by the invention unloads ladder, only Quick-release pin 5 need be laid down from the Quick-release pin mounting hole bearing pin b4, then the bar of the ladder of ladder hook 6 along bearing pin b4 be skidded off, save manpower.
More than be described in detail in conjunction with ladder hanging rack structure specific embodiment of the present invention, but be not limitation of the present invention, everyly according to technical spirit of the present invention, technical scope of the present invention is all belonged to any simple modification made for any of the above embodiments, also it should be noted that, comprise the combination in any between each part mentioned above according to the category of ladder hanging rack structure technical scheme of the present invention.
