Abstract
The utility model relates to a boom lifting device. The boom lifting device comprises a bottom plate, two supports installed on the two sides of the upper end of the bottom plate, adjusting plates with the bottoms installed on the supports through hinge pins II in a rotating mode, a jacking support arranged at the upper end of the bottom plate, and two jacks arranged below the jacking support and on the two sides of the bottom plate. Two flexible connection devices are fixed to the lower end of the jacking support, and the adjusting plates are fixed inside the flexible connection devices in a sliding mode. A hole with the diameter larger than the outer diameter of a boom is formed in the middle of the bottom plate, and the boom is locked by nuts after penetrating through the hole. After the boom is fixed to the bottom plate through the nuts, the jacks can drive the jacking support to ascend or descend, the jacking support ascends or descends and utilizes the adjusting plates to drive the bottom plate to drive the boom to ascend or descend through the flexible connection devices, and therefore adjustment of the elevation of equipment under the boom is achieved conveniently. Thus, the shortcoming that adjustment through a traditional chain block is inconvenient is overcome, and the safety is improved.

The beneficial effects of the utility model are: after suspension rod is fixed on base plate by nut, can drive lifting-up support to promote or landing by jack, the lifting of lifting-up support utilizes regulating plate to drive base plate to drive suspension rod to realize by articulating device and promotes or landing, realized easily the adjustment work of equipment absolute altitude under suspension rod.Due to this suspension rod bont assembling flexibly and adjust regulating plate connecting length therein by articulating device, the lifting of suspension rod that can different size easy to use.Therefore overcome the inconvenience that traditional chain block is adjusted, and improved safety.
Brief description of the drawings
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is side-looking structural representation of the present utility model;
In figure, 1. lifting-up support 2. jack 3. connecting panel 4. bearing pin I 5. spring cotter I 6. regulating plate 7. base plate 8. hole 9. suspension rod 10. nut 11. bearing 12. bolt 13. bearing pin II 14. spring cotter II 15. pin-and-holes.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, accompanying drawing 2, the utility model is described further.
This suspension rod bont, two bearings 11, bottom that comprise base plate 7, are installed on base plate 7 both sides, upper end are rotated the regulating plate 6 that is installed on bearing 11, are arranged at the lifting-up support 1 of base plate 7 upper ends and are arranged at lifting-up support 1 below and be positioned at two jacks 2 of base plate 7 both sides by bearing pin II 13, lifting-up support 1 lower end is fixed with two articulating devices, regulating plate 6 is slidably fixed in articulating device, the middle part of base plate 7 is provided with the hole 8 that diameter is greater than suspension rod 9 external diameters, and suspension rod 9 is rear by nut 10 lockings through hole 8.After suspension rod 9 is fixed on base plate 7 by nut 10, can drive lifting-up support 1 promote or land by jack 2, the lifting of lifting-up support 1 utilizes regulating plate 6 to drive base plate 7 to drive suspension rod 9 to realize by articulating device and promotes or landing, realized easily the adjustment work of 9 times equipment absolute altitudes of suspension rod.Due to this suspension rod bont assembling flexibly and adjust regulating plate 6 connecting length therein by articulating device, the lifting of suspension rod 9 that can different size easy to use.Therefore overcome the inconvenience that traditional chain block is adjusted, and improved safety.
Above-mentioned articulating device comprises two slide plate groups that are individually fixed in lifting-up support 1 lower end, each slide plate group is made up of two connecting panels 3 that are vertically installed on lifting-up support 1 lower end and be parallel to each other, spacing between two connecting panels 3 in each slide plate group and the gauge of regulating plate 6 match, connecting panel 3 and regulating plate 6 are respectively arranged with some pin-and-holes 15 from top to bottom, and regulating plate 6 slides to be plugged in slide plate group and by bearing pin I 4 and inserts in pin-and-hole 15 and be connected and fixed.Slide in slide plate group by regulating plate 6, can adjust according to the jack of different tonnages 2 spacing of lifting-up support 1 and base plate 7, after adjusting to the right place, make regulating plate 6 and the pin-and-hole 15 on connecting panel 3 coincide, insert afterwards after bearing pin I 4 and can realize and being connected and fixed, adjustment work is simple and convenient.
