Has the advantages that: compared with the prior art, the utility model discloses a lamp pole main part includes outside dead lever and inside lifter to electric liquid push rod drives the lifter in dead lever inner chamber elevating movement as lift actuating mechanism, and not only simple structure, reasonable, moreover, the operation is simple and easy, the fault rate is low, has good practicality and market prospect.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Example (b):

the electro-hydraulic lifting court lighting lamp pole comprises a fixing rod 2, a lifting rod 4 and a lifting driving mechanism, wherein the lifting rod 4 is assembled in the inner cavity of the fixing rod 2 in an inserting mode, and the lifting driving mechanism drives the lifting rod 4 to move up and down in the inner cavity of the fixing rod 2.

The fixed rod 2 is a square tube with 258mm 4200mm, and a base 1 is fixed at the bottom end of the fixed rod. The lifting rod 4 is a square tube with the thickness of 200mm 3000mm, and the top end of the square tube is closed by a top plate 6. A lamp supporting device 7 for assembling a lamp 71 is fixed on the top of the top plate 6.

The lifting driving mechanism is a conventional electro-hydraulic push rod and sequentially comprises a motor 11, a bidirectional hydraulic pump 9 and a hydraulic oil cylinder 8 with the stroke of 3m from bottom to top, the motor 11 drives the bidirectional hydraulic pump 9 to output pressure oil in a positive and negative mode through positive and negative rotation and sends the pressure oil to the hydraulic oil cylinder 8, and reciprocating motion of a piston rod is achieved. The hydraulic oil cylinder 8 is positioned in the inner cavity of the lifting rod 4, and the top end of a piston rod of the hydraulic oil cylinder is fixedly connected with the top plate 6 at the top of the lifting rod 4; the bidirectional hydraulic pump 9 is located below the lifting rod 4 and fixed on the inner wall of the fixed rod 2 through connecting trunnions 10 at two sides of the bidirectional hydraulic pump.

The outer walls of a circumference of the bottom port of the lifting rod 4 are all fixed with lifting guide sliding blocks 3; the inner walls of a circumference of the top end opening of the fixed rod 2 are all fixed with fixed guide sliding blocks 5; the thickness of the lifting guide sliding block 3 is the same as that of the fixed guide sliding block 5, and the thickness of the lifting guide sliding block is slightly smaller than the gap between the inner wall of the fixed rod 2 and the outer wall of the lifting rod 4. Lifting guide slider 3 and fixed guide slider 5 all adopt the nylon sliding block, play direction and lubrication action, can not only prevent lifter 4 at lift in-process off tracking, the inner wall of friction dead lever when still can avoiding lifter 4 to go up and down reduces lift resistance, increase of service life.

At darker and night, when need use the light to throw light on basketball court, through motor 11 corotation, drive two-way hydraulic pump 9 positive transport pressure oil to hydraulic cylinder 8, hydraulic cylinder 8's piston rod upwards stretches out, and then drives lifter 4 and upwards rises. When the lighting lamp is not needed to illuminate the basketball court, the motor 11 is rotated reversely to drive the bidirectional hydraulic pump 9 to reversely convey pressure oil to the hydraulic oil cylinder 8, and the piston rod of the hydraulic oil cylinder 8 retracts to further drive the lifting rod 4 to descend downwards.

The above is only the embodiment of the present invention, not the limitation of the patent scope of the present invention, all the equivalent structures made by the contents of the specification and the drawings are directly or indirectly applied to other related technical fields, all the same principle is within the patent protection scope of the present invention.
