The utility model has the advantages of simple structure, high transmission efficiency, and work of long stroke and low stroke frequency realization.
Description
Tower shelf type oil pumping machine belongs to oil recovery machiner.
At present, the pumping unit of Oilfield using mainly contains two kinds, a kind of two sprocket wheel tower frame type numerical control oil pumping units for Baoji Petroleum Machinery Factory's development, another kind of ROTAFLEX pumping unit for the introduction of triumph petroleum machinery manufacturing company.First kind owing to adopt the top-driving scheme, and the volume and weight of drive system is limited to some extent, and inconvenience is generally used; The center of gravity height, poor stability; Maintenance needs with long-armed, gross ton position crane, running repairs inconvenience.Second kind of mechanism's complexity costs an arm and a leg.
It is a kind of simple in structure, easy to maintenance that the purpose of this utility model is to provide, and have higher transmission efficiency, can realize long stroke, the tower shelf type oil pumping machine of low jig frequency.
The purpose of this utility model is achieved in that this tower shelf type oil pumping machine is by power section, brake portion, supporting part, drive part and control section are formed, its structure accompanying drawings is as follows: drive part adopts three wheel systems, promptly by a driving wheel 16 and two upper saw pulleys 9,10 and flexible member form, driving wheel 16 is supported on the base 1 by bearing support 17, and drive by retarder 18 by reversing motor 21, upper saw pulley 9,10 are arranged on the upper mounting plate 7 of pylon 2 supports, flexible member pile warp driving wheel 16 and two upper saw pulleys 9,10, the one end is connected with counterweight 14 by counterweight connector 13, and the other end is connected with suspension point 5 by tensioning connector 6.
This machine is under the control section effect, and control reversing motor 21 is done positive and negative rotation.If clockwise rotate, then suspension point 5 is transferred by flexible member 15, connector 3, flexible member 4, upper saw pulley 9 and tensioning connector 6; Simultaneously, by flexible member 15, connector 11, flexible member 12, upper saw pulley 10 and counterweight connector 3 counterweight 14 is mentioned.If rotate counterclockwise, then counterweight 14 is put down, suspension point 5 is mentioned.So do action is finished the required key operation of pumping unit.
Because the utility model places the bottom with drive part, drive three wheel drive mechanisms by reversing motor, thereby make the overall structure of pumping unit simple, for running repairs and maintenance provide convenience, transmission efficiency is obviously improved, particularly can realize the target of long stroke (more than the 8M), low jig frequency (2.4 times/minute).
Further specify concrete structure of the present utility model and working condition thereof below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation according to a kind of tower shelf type oil pumping machine that the utility model proposes.
Fig. 2 is that the A of Fig. 1 is to view.
Its power section places on the base 1 of pumping unit.It is made of reversing motor 21, coupling 19, retarder 18 and bearing support 17, reversing motor under the control section effect, but carry out de-rotation, thereby realize the oil pumping operation.
Brake portion is made of break 20 and coupling 19.Break is selected no electric normal close type for use.During normal operation, power on to pedal and open a sluice gate sheet, allow coupling freely to rotate; When pumping unit was unusual, can cut off the power supply made the break band-type brake.
Supporting part is made of base 1, pylon 2 and upper mounting plate 7.Its effect mainly be two upper saw pulleys 9 and 10 are lifted high, for suspension point 5 and counterweight 14 provide enough vertical displacement spaces.
Drive part mainly is made up of a driving wheel 16 and two upper saw pulleys 9,10 and flexible member.Driving wheel 16 is supported on the base 1 by bearing support 17, and this is taken turns by reversing motor and drives through retarder 18, and upper saw pulley 9,10 is fixed on the upper mounting plate 7.Flexible member pile warp driving wheel and two upper saw pulleys, its two ends are connected with counterweight 14 by counterweight connector 13 respectively, are connected with suspension point 5 by tensioning connector 6.Suspension point 5 links to each other with the sucker rod of down-hole.
Flexible member can adopt one or both.If employing is a kind of, should be chain or single face synchronous cog belt.If adopt two kinds, the flexible member 15 of pile warp driving wheel 16 can adopt chain or single-face tooth-shaped band, and the flexible member 4,12 of pile warp upper saw pulley 9,10 can adopt wire rope, and employing connector 3 is connected with 11 between flexible member 4,12 and the flexible member 15.
In order to guarantee that flexible member has enough intensity to satisfy the needs of pumping unit suspending point loading, driving wheel 16 can adopt the duplicate sprocket structure, and is corresponding with it, and upper saw pulley 9,10 adopts equal diameters or bigger duplicate sprocket.Driving wheel 16 also can adopt duplicate gear, and at this moment, upper saw pulley 9 and 10 also adopts the bigger two-sided light face wheel of diameter, and flexible member is the single face synchronous cog belt.If flexible member adopts two kinds, promptly when chain or single face synchronous cog belt and wire rope combining form, upper saw pulley 9,10 adopts duplex light faces to take turns and gets final product.Certainly, upper saw pulley and driving wheel also can be made the simply connected form, and flexible member can adopt more than one group.
DHC14-8 machine according to the utility model design: 14 tons of suspending point loadings, stroke 8M.Single reduction gear velocity ratio i=40.5,1.2 tons of weight, specified output torque 35.9KN-M, efficient is 92%～96%.The surface efficiency of equipment is higher than 82%, and system effectiveness is higher than 55%.
