A kind of base radial type of the utility model High-Pole Lamp tower screw elevator, motor (5) and reductor (7) are installed in the bottom of vehicle frame (3), wherein, motor is installed on the crossbeam of vehicle frame (3) rear side, reductor is installed on the crossbeam of vehicle frame (3) front side, motor and speed reducer is connected by " Z " type V-wheel drive, the long 1000mm of pitchline of V belt; Rubber wheel (6) is housed below the bottom of vehicle frame;
One screw rod guide groove (4) level is installed in the U type groove on two vertical support frame tops of vehicle frame (3), and the left end of this screw rod guide groove (4) has the journal stirrup of a band fraising, and with pressing plate (11) the screw rod guide groove is fixed;
The right-hand member of small rack (1) has internal thread hole, and the bottom of its left end is connected with screw rod guide groove (4) with bolt, and is embedded with plain thrust bearing (2) in the bottom of the small rack of this junction;
One screw rod (10) passes the internal thread hole of above-mentioned screw rod guide groove (4) and plain thrust bearing (2) and small rack (1) right-hand member, and on the screw rod (10) that is positioned between holding about small rack (1), tapped gear (9) being installed, the screw-internal thread fit that screw rod (10) passes this gear (9) connects;
Output gear (8) that reductor (7) mouth is installed and above-mentioned tapped gear (9) engagement.
Right-hand member at screw rod (10) has a detouchable to have the journal stirrup (13) that diameter of phi 45mm reams, can be hinged with the fraising of beacon bottom, and screw rod is made screw thread Tr80 * 14, length 1620mm by 20# steel Φ 83 * 16 solid drawn pipes;
Small rack (1) is made by the 20# steel, left and right two ends are respectively a circular steel plate, periphery is welded by hexagonal angle by three angle bar frames, cylindrical, diameter Ф 400mm, height 400mm, there is the circular hole of diameter of phi 80mm at described circular steel plate middle part, screw rod (10) passes from the hole, to guarantee the stable of screw rod;
Plain thrust bearing (2) model is 8316, is used for the friction of supporting gear (9) when reducing to rotate;
Vehicle frame (3) is welded with Q235-AF angle steel L50 * 5 and L80 * 6, is rectangle the inboard parallel flat crossbeam of the six roots of sensation that is welded with of vehicle frame;
The screw rod guide groove is made with 20#, Φ 121 * 12 solid drawn pipes, and internal diameter Φ 80mm, long 1200mm are cylindrical;
