Abstract
The utility model provides a belt pressing mechanism which comprises a rotary drum which is connected with a drive shaft. An arc groove is arranged in the external side wall of the rotary drum in a penetrating mode along the axial direction. Baffles are respectively fixedly connected at two ends and the middle of the rotary drum. Press shafts which are fixedly connected with the baffles are arranged above the arc groove. Two wedge blocks which are opposite in direction are respectively arranged between two ends of the rotary drum and between the press shaft and the arc groove. Belt connected with a beam hanger and a counter balance are respectively wound on two segments of the rotary drum. End portions of the belts penetrate through gaps between the wedge blocks and the arc groove to be wound on the rotary drum and drive the wedge blocks to move forwards under the action of the belts so as to enable the wedge blocks to press the belts tightly. As the two wedge blocks are opposite in direction, the two belts connected with the beam hanger and the counter balance rotate oppositely, thus, torsion output by the drive shaft is reduced, the load of a drive motor is effectively reduced and the aims of saving energy and reducing consumption are achieved.
Description
Technical field
The utility model relates to a kind of used for oil extractor assisting agency, especially a kind of belt hold-down mechanism.
Background technique
When pumping unit is pumped operation, drive motor drives counterweight and rope hanger to-and-fro motion by belt, belt is wrapped on the head roll, and the belt winding direction on head roll that links to each other with counterweight with rope hanger is identical, pumping unit is in when operation like this, two belt producing balanced forces, and the moment of two belts all is increased on the input torque of live axle, thereby increased the load of drive motor, do not reached energy-saving and cost-reducing purpose.The existing deficiency of prior art that Here it is.
Summary of the invention
The technical problems to be solved in the utility model is exactly for the existing deficiency of prior art, and provides a kind of energy consumption low belt hold-down mechanism.
This programme is achieved by the following technical measures: this belt hold-down mechanism comprises the cylinder that links to each other with live axle, run through vertically on the described cylinder outer side wall and be provided with arc groove, the two ends of cylinder and centre are fixedly connected with respectively baffle plate, and there is the last item that is fixedly connected with baffle plate the arc groove top; Between two ends, last item and the arc groove of cylinder, be respectively arranged with voussoir, the opposite direction of two voussoirs.
Above-mentioned baffle plate and cylinder are coaxial with live axle.
Above-mentioned cylinder is circular bored roll, can alleviate like this weight of whole mechanism.
Above-mentionedly be fixedly connected as welding.
The beneficial effect of this programme can be learnt according to the narration to such scheme, in this belt hold-down mechanism, run through vertically being provided with arc groove on the cylinder outer side wall, the two ends of cylinder and centre are fixedly connected with respectively baffle plate, and there is the last item that is fixedly connected with baffle plate the arc groove top; Between two ends, last item and the arc groove of cylinder, be respectively arranged with voussoir, the opposite direction of two voussoirs.Be wrapped in respectively on two sections cylinders with the belt that rope hanger links to each other with counterweight, after space between voussoir and the arc groove is passed in the end of belt, be wrapped on the cylinder, under the active force of belt, drive voussoir and move forward together, thereby make voussoir compress belt, because the opposite direction of two voussoirs, so the two belt rotation directions that link to each other with rope hanger with counterweight are opposite, so just reduced the input torque of live axle, thereby effectively reduced the load of drive motor, reached energy-saving and cost-reducing purpose.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is apparent.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is A-A sectional view among Fig. 1.
Among the figure, 1 is baffle plate, and 2 is baffle plate, and 3 is cylinder, and 4 is baffle plate, and 5 is voussoir, and 6 is last item, and 7 is arc groove, and 8 is keyway.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
A kind of belt hold-down mechanism, as depicted in figs. 1 and 2, it comprises the circular bored roll 3 that is connected with the driving axle key, run through vertically on described cylinder 3 outer side walls and be provided with arc groove 7, the two ends of cylinder 3 are welded with respectively baffle plate 2 and baffle plate 4, the centre is welded with baffle plate 1, and baffle plate 2, baffle plate 4, baffle plate 1 and cylinder 3 and the coaxial setting of live axle, and there is the last item 6 that is welded and fixed with baffle plate 2, baffle plate 4 and baffle plate 1 arc groove 7 tops; Between two ends, last item 6 and the arc groove 7 of cylinder 3, be respectively arranged with the opposite direction of voussoir 5, two voussoirs 5.
During use, the voussoir 5 at cylinder 3 two end part and the space between the arc groove 7 are passed respectively in the end of two belts that will link to each other with counterweight with rope hanger, under the initial action power of belt, drive voussoir 5 and travel forward together, thereby make voussoir 5 compress belts; Owing to voussoir 5 opposite directions on two sections cylinders 3, so two belts twine along counterclockwise and clockwise direction respectively on corresponding cylinder 3, and the winding along with belt, the impacting force of 5 pairs of belts of voussoir is larger, thereby has realized need not external force or external equipment can firmly be fixed on belt on the cylinder 3.Because the winding direction of two belts is opposite, when live axle drove cylinder 3 rotation, two belts shrank respectively winding and lengthen, and the input torque that two belts are acted on the live axle has reduced, thereby has reduced the load of drive motor, had reached energy-saving and cost-reducing purpose.
Can pass through existing techniques in realizing without the technical characteristics of describing in the utility model, not repeat them here.
