Description
Technical field
The utility model belongs to heavy duty equipment field, particularly relates to a kind of manual winding devices for various crane cabin escape ladder lifting.
Background technology
Driver's cab escape ladder jacking system often adopts manually many row's multilayer reel wound devices.Steel rope on escape ladder is fixed on spool by directional wheel, rotates lay winding wire ropes by the handle on spool, make escape ladder do upper and lower straight-line motion.Shortcoming reel does not have steel rope guide groove, and this makes the wirerope-winding in spool uneven, often occurs laminating and stuck situation mutually due to steel rope, and side-rolling ladder body can not move up and down, and manual single reel wound device does not possess interlock function.
Summary of the invention
The purpose of this utility model is to overcome shortcoming of the prior art, and provides a kind of manual winding devices for escape ladder lifting.
The technical scheme that the utility model adopts: a kind of manual winding devices for escape ladder lifting, it is characterized in that: comprise the bearing be installed on escape ladder fixed frame, bearing is provided with the worm reduction gear with manual shake function, the slow-speed shaft of worm reduction gear is provided with the reel for lay winding wire ropes, described reel is provided with guide groove, and steel rope can become scroll-type to be wrapped in the guide groove of reel.
Described reel by the spool spindle be installed on the slow-speed shaft of worm reduction gear, be arranged at two side plates on spool spindle and be arranged on spool spindle and spacing sleeve between biside plate forms, the cavity between biside plate is guide groove.
Two side plates of described reel and spacing sleeve are fixed on spool spindle by spool spindle tie bolt.
A side plate in two side plates of described spool spindle is positioned at guide groove bottom position and is provided with a wire rope hole, the side being positioned at the wire rope hole outside side plate is provided with a steel wire clamping plate for fixing steel rope.
The described worm reduction gear with manual shake function is a worm reduction gear being provided with manual tilter, and described manual tilter comprises the rocking bar be connected with the high speed shaft of worm reduction gear and the handle being arranged at rocking bar tail end by bearing pin.
Described rocking bar is fixedly connected with the high speed shaft of worm reduction gear by holding screw.
The utility model has the advantage of that mechanism is simple, reliable, stressed little, the long service life of steel rope, applied widely, it can be widely used in the manual winding devices of the driver's cab escape ladder lifting on various hoisting crane.

Detailed description of the invention
As shown in Figure 1,2,3, 4, a kind of manual winding devices for escape ladder lifting, comprise the bearing 9 be installed on escape ladder fixed frame 17, bearing is installed with by bearing tie bolt 8 worm reduction gear 7 that has manual shake function, the high speed shaft of worm reduction gear is installed with a rocking bar 12 by holding screw 13, the end of rocking bar 12 is provided with handle 11 by bearing pin 10, shakes rocking bar 12 worm reduction gear can be driven to rotate by handle 11.The slow-speed shaft of worm reduction gear 7 is installed with a reel 1 for lay winding wire ropes, reel 1 by the spool spindle 4 be installed on the slow-speed shaft of worm reduction gear, be fixedly installed in two circular side panel 14,15 on spool spindle 4 by spool spindle tie bolt 3 and annular space overlaps 2, wherein spacing sleeve 2 is form guide groove 16 between biside plate between biside plate, the bottom position that side plate 14 is positioned at guide groove 16 has a wire rope hole, and the position being positioned at threaded hole of steel side outside side plate 14 is provided with a steel wire clamping plate 6 for fixing steel rope 5.
Utility model works process is as follows: the manual winding devices being arranged on the lifting of crane cabin escape ladder is fixed on the framework of escape ladder, being rotated by wind makes worm reducer high speed shaft operate, worm screw in worm reducer drives worm gear, worm gear drives the slow-speed shaft of reductor, worm reduction gear slow-speed shaft drives spool spindle to make spool spindle drive reel together to rotate, thus steel rope is wrapped on reel along reel guide groove.When worm reduction gear drives in the wrong direction, by reducing the moment of wind, reel is reversed in tow by steel rope, and correspondingly steel rope pulls out from reel guide groove.
