As shown in the figure, the little loop wheel machine of this high building comprises actuating unit, support and handling whirling arm mechanism, actuating unit comprises pedestal 1, support 2, hog frame 3, handling whirling arm mechanism 4, on the pedestal 1 hoisting mechanism is installed, support 2 and hog frame 3 all are fixed on the pedestal 1, the top of support 2 and hog frame 3 all is set with a top cap 10, interfixes by twice transverse link clip structure 5 between support 2 and the hog frame 3; Support 2 is by lower fulcrum bar 21, screw rod 22, push rod 23 constitutes, be provided with rope winding jib 11 near the hoisting mechanism place on the lower fulcrum bar 21, level indicator 114 and level indicator 115 (referring to Fig. 3), handling whirling arm mechanism 4 comprises support sleeve 45, arm, arm tows 44, wherein arm is made of leading portion 41 that is made into integration and back segment 42, front and back section 41, fold an obtuse angle between 42, and also being provided with one between two sections strengthens with strut bar 43, arm is hingedly mounted on the support sleeve 45 by back segment 42, the arm of making by steel rope tow 44 two ends respectively with support sleeve 45 and arm back segment 42 near captiveing joint at leading portion 41 places, section 41 before and after the arm, the axis of 42 axis and support sleeve 45 is in the same plane, and leading portion 41 axis and support sleeve 45 axis angles are greater than the angle of back segment 42 axis and support sleeve 45 axis, handling whirling arm mechanism 4 is sleeved on by support sleeve 45 on the push rod 23 of support 2, and support sleeve 45 lower ends are supported on the bearing 24 that is provided with on the push rod 23; Link to each other with suspension hook 9 behind the pulley that the steel rope of hoisting mechanism is provided with through rope winding jib 11 and and the arm middle part and leading portion end of passing support sleeve 45 tops, arm back segment 42 is provided with the anti-collision block 46 with support sleeve 45 cooperatings, also is provided with the position limiting structure that is made of trigger point 7 and travel switch 8 between back segment 42 and the support sleeve 45 simultaneously; Hog frame 3 is made of lower fulcrum bar 31, screw rod 32, push rod 33 equally, and different is with support 2, and push rod 33 is made of multistage, between adjacent two sections push rods by being threaded.
Shown in Fig. 2,3,8, steel rope rope winding jib 11 is made of row's rope sheave support 111, pivot shaft 112 and row's rope sheave 113, row's rope sheave 113 rotatable being sleeved on the pivot shaft 112, and can slide along pivot shaft 112 axis, row's rope sheave support 111 inside are fluted body structures, and pivot shaft 112 is installed in the groove and can slides in this groove.Steel rope rope winding jib 11 is fixed on the lower fulcrum bar 21 of support 2 by its row's rope sheave support 111; Also be provided with the level indicator 115 and the level indicator 114 that are used to indicate described pedestal 1 and support 2 whether parallel, vertical on the described rope winding jib 11.
As shown in Figure 4, trigger point 7 is provided with the cushion rubber of being made by flexible materials such as rubber, plastics 72 by body 71 and its and constitutes.
As shown in Figure 5, the top cap 10 on support 2 and hog frame 3 tops is made of the gusset 104 of seat board 101, installation sleeve 103, several one-tenth radial arrangement, is distributed with several through holes 102 on the seat board 101.
As shown in Figure 6, the adjacent push rod section joint of hog frame 3 also is provided with securing rod 15, and these securing rod 15 two ends are fixing with the welding of two push rod sections respectively.
During work, at first little loop wheel machine is fixed in the room, its concrete steps are: connecting rod 5 gets loose, adjusting screw rod 22,32 respectively leans on top ceiling the top cap 10 on support 2 and the hog frame 3, be screwed into clamped spiked by the through hole on the top cap seat board 101 102 to top ceiling, installing connecting rods 5, and at the push rod section joint of hog frame 3 welding securing rod 15; Then,, it is stretched out outside the window, can carry out hanging in weight outside the building in the room or in the room, carry out the lift heavy operation that weight is carried by adjusting the luffing angle of arm.
The little loop wheel machine of high building in the past, because its arm is a straight-arm, for guaranteeing the stability of loop wheel machine, must keep the safe angle of a minimum between arm and the support sleeve, the maximum angle between arm and the support sleeve just equals above-mentioned minimal security angle and its maximum activity flip angle sum like this; And after the utility model changes arm into curved boom, even the arm back segment is recovered to the state parallel with support sleeve, because of weight still and remain with certain distance between the support sleeve, thereby still can guarantee the stability of loop wheel machine; Therefore, after changing arm into curved boom, reduced the minimal security angle between arm back segment and the support sleeve greatly, also having reduced the arm back segment thus overturns downwards afterwards and the maximum angle between the support sleeve, thereby reduced when arm carries out pitch regulation requisite space in the size of vertical direction, thereby satisfied the requirement of using at the wicket position.
After anti-collision block 46 is set on the arm back segment, when upwards overturning arm, can avoid making trigger point 7 break travel switch 8 because of arm upwards excessively overturns.
Because in practical work process, to carry out the pitching operation of arm continually, like this after between arm back segment and the support sleeve position limiting structure that is made of trigger point 7 and travel switch 8 being set, utilize travel switch can cut off the work of hoisting mechanism, thereby arm is limited on minimal security angle or the position greater than the minimal security angle, to guarantee the safe in utilization of little loop wheel machine.
Owing to by being threaded, therefore, behind the push rod section joint welding securing rod that adjusting puts in place, can prevent the accidental release of threaded connection between each push rod section of hog frame 3.
After on the lower fulcrum bar 21 rope winding jib 11 being set, can effectively prevent to cause confusion in the steel rope folding and unfolding process, to guarantee the normal operation of hoisting mechanism.
Because the handling whirling arm mechanism in the little loop wheel machine is supported on the support 2 fully, and support self is fixed in the mode of pushing tow up and down, therefore, level indicator 12 is set on lower fulcrum bar 21, guarantee the squareness of support 2, can guarantee that support is in good strained condition, to guarantee the safety of little loop wheel machine.
In the past, the support in the little loop wheel machine only leaned against on the top ceiling by its top crown and fixed, and like this, in case becoming flexible appears in screw rod and push rod junction, will directly threaten the safety of little loop wheel machine.After being fixed on the top ceiling by clamped spiked the top cap, support and hog frame reliability of fixation have been improved, for the safe operation of little loop wheel machine provides guarantee.
In the above-described embodiment, hog frame 3 lower ends are directly installed on the pedestal, and in addition, hog frame 3 lower ends also can be provided with independently base (not shown).When hog frame 3 lower ends are supported on independently on the base, can conveniently adjust the spacing between hog frame and the support, so that on-site installation and guarantee whole little loop wheel machine reliability of fixation.
Position limiting structure on the handling whirling arm mechanism is form setting as shown in Figure 7 also, and this position limiting structure is made of travel switch 8, fork 14, on the swing rod 13 that fork 14 hinged installation arm leading portions 41 are provided with.Swing rod 13 is the U type, fork overturn downwards and the contacting of disengaging and travel switch 8 after, lean on the web of swing rod 13.Fork 14 free ends be positioned at suspension hook 9 directly over, like this, upwards in the rise process, will touch fork 14 at suspension hook 9, by 8 work of fork 14 trigger switches, and cut off the work of hoisting mechanism, thereby realize qualification suspension hook 9 rising end positions.
