Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1-2, a kind of spiral down conductor lifting device of the utility model comprises: base 10, helical axis 11, spiral plate 12, bearing plate 7, footstock 5 and for clamping the clamping unit of down conductor; One end of helical axis 11 is provided with leading screw top platform 8, the other end is provided with screw thread (as Fig. 3), leading screw top platform 8 is the boss that are structure as a whole with helical axis 11, bearing plate 7 is socketed on helical axis 11 by the through hole arranging in the middle, bearing plate 7 is positioned at the inner side of leading screw top platform 8, leading screw top platform 8 is for limiting bearing plate 7, prevents that its end to helical axis 11 from moving; Spiral plate 12 is by arranging being threaded of screwed hole in the middle and helical axis 11 other ends; Footstock 5 and base 10 lay respectively at the both sides of helical axis 11, and one end of footstock 5 and base 10 is all hinged with the two ends of spiral plate 12 respectively by connecting rod 13, and the other end of footstock 5 and base 10 is all hinged with the two ends of bearing plate 7 respectively by connecting rod 13; Clamping unit is connected with footstock 5.
Clamping unit comprises fixed head 2 and clamping screw 3, fixed head 2 is provided with connecting hole and clamping slot, fixed head 2 is connected with footstock 5 with connecting hole by bolt, one end of clamping screw 3 penetrates in clamping slot, for 1 being clipped in clamping slot going between under ground connection, the other end of clamping screw 3 is provided with fastening handle 4, for rotating clamping screw 3 (as Fig. 4,5); Clamping screw 3 penetrates the one end in clamping slot, is connected with pressing plate, and pressing plate can rotate freely around clamping screw 3.
The place that footstock 5 is connected with connecting rod 13 towards a side of helical axis 11 with base 10, be equipped with two connecting plates that are parallel to each other 6, two connecting plates 6 are all perpendicular to footstock 5 or base 10, connecting plate 6 is all provided with connecting hole (as Fig. 6,7), the end of connecting rod 13 is stretched between two connecting plates 6, the end of connecting rod 13 is installed with pin, and the two ends of pin are connected in the connecting hole of two connecting plates 6, has realized the hinged of footstock 5 or base 10 and connecting rod 13.
