Preferably: one end and the base of described motor are hinged, the other end is fixed by screw rod and the base being used for adjusting motor angle of inclination, and motor horizontal tilt adjustment indirectly can regulate the tightness of belt, uses more flexible.
Preferably: described belt adopts common V-type band or the high Timing Belt of transmission efficiency.
Preferably: described pylon is positioned at the regulating wheel being also fixed with above large belt wheel and putting forward counterweight pull rope degree of tightness for adjustment second.
Preferably: described guide wheel units comprises support bar and guide wheel, one end of described support bar and one end of upper mounting plate are hinged, and the other end and guide wheel are hinged.Support bar and the hinged structure of upper mounting plate can make the angle adjustable of support bar, and then regulate guide wheel angle, improve the convenience degree of sucker rod and oil well mouth fine position.
Preferably: the upper end of the upper mounting plate of described pylon is also provided with protective cover.
The utility model beneficial effect is compared with prior art: 1, pylon is ready-made triangle " A " shape, and compare other forms (square, circle), under identical consumptive material, triangular structure is the most stable and firm, and complete machine safety in operation is high.2, complete machine structure is simple, and each component layouts is reasonable, and floor space is little.3, motor carries electricity loss brake, elevator wheel is provided with energising brake, and double brake is protected.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is made a detailed explanation.
The novel pylon energy-saving beam pumping unit of one as shown in Figure 1, comprise the pylon be fixed on base 15, large elevator wheel 1 is fixed with in the middle part of the upper mounting plate 16 of described pylon, and one end of upper mounting plate 16 is also fixed with guide wheel units 3, described large elevator wheel 1 is connected with first and carries sucker rod pull rope 2, described first carries sucker rod pull rope 2 walks around guide wheel units 3 and is connected with polished rod eye 4, described polished rod eye 4 fixes with sucker rod 6, described large elevator wheel also carries counterweight pull rope 17 by first and is fixedly connected with the balancing weight 19 being positioned at the pylon other end, the coaxial driving elevator wheel 9 connected is fixed with in the middle part of described pylon, brake 8 and large belt wheel 10, described driving elevator wheel 9 and large elevator are taken turns between 1 and are carried respectively by second the connection for transmission that sucker rod pull rope 18 carried by counterweight pull rope 5 and second, the bottom of described pylon is also provided with motor 12 and switch board 20, the driving shaft of described motor 12 is provided with small pulley 13, belt transmission is passed through between described small pulley 13 and large belt wheel 10.
One end and the base 15 of described motor 12 are hinged, and the other end is fixed with base 15 by the screw rod 14 being used for adjusting motor angle of inclination.Described belt 11 adopts common V-type band or the high Timing Belt of transmission efficiency.Described pylon is positioned at the regulating wheel 7 being also fixed with above large belt wheel 10 and putting forward counterweight pull rope 5 degree of tightness for adjustment second.Described guide wheel units 3 comprises support bar and guide wheel, and one end of described support bar and one end of upper mounting plate are hinged, and the other end and guide wheel are hinged.The upper end of the upper mounting plate 16 of described pylon is also provided with protective cover.
Operating principle of the present utility model: the rotating of motor, is slowed down by belt and is delivered on " driving elevator wheel " assembly, finally drive large elevator to take turns rotating, thus sucker rod and counterweight pump, realize oil pumping.The force analysis of specific works process is as follows,
