Description
Technical field
The utility model relates to mechanical manufacturing field, is a kind of equipment that is used for oil exploitation.
Background technology
One Chinese patent application numbers 88101274 discloses a kind of " chain reciprocating oil pumping unit "; By two pairs of intermeshing synchronous pinion gears and synchronous gear wheel, the drive sprocket that is hinged through reciprocal chain and driven sprocket, the connecting axle, connecting rod, slide block, reciprocating lever, frame, oil pump and the motor composition that are hinged with reciprocal chain.Adopt the sleeve-barrel roollr chain-drive mechanism, improve 0.5 times than the oil pumping amount of existing petroleum extractor, one times of save power does not need reductor.
One Chinese patent application numbers 200720030271.7 discloses a kind of " removable balance weight formula oil pumper "; It comprises crossbeam, power distribution cabinet, and power distribution cabinet connects the motor drives guide wheel and rotates, and guide wheel moves up and down crossbeam through connecting rod; Crossbeam is seated on the base bearing of big boom support top; The front portion of crossbeam is the horse head plait that horse head is connected with it, and the below is connecting polished rod pin, polished rod, through flow process and petroleum pipeline transfer oil; On crossbeam, be provided with mobile balanced block, mobile balanced block is controlled by mobile controlling organization.Adopt after the said structure, because balance weight can be along with crossbeam moves up and down under control automatically, thereby saves energy can prevent belt creep.
Traditional beam type petroleum extractor used more than 100 year in the world.At present, this oil pumper still generally adopts in countries in the world, though this oil pumper structure is huge, operational shock is big, and energy consumption is high, and is because it is sturdy durable, still good by the user.
Summary of the invention
The purpose of the utility model has provided a kind of compact conformation, the pulse free that operates steadily, can a machine gang pumping drum-type pulse free petroleum extractor.
The described drum-type pulse free of the utility model petroleum extractor is by motor, VFC case, cylinder, roller, clamping plate, guide rail, slide block, wire rope, pulley and be configured to, and support is fixedly connected with the basis, ground, and cylinder passes through bearing support and ground is basic is fixedly connected; Pass through the propeller shaft couplings of shaft coupling and cylinder by the motor of VFC case control; Cylinder is provided with the ring seal skewed slot, moves in the ring seal skewed slot of roller on cylinder, and clamping plate have two parts up and down; To up and down by bolt, two parts are fixedly connected with wire rope; The axle of roller is fixedly connected with the top of clamping plate, and slide block is fixedly connected with the lower part of clamping plate, and slide block moves in guide rail; Guide rail is fixedly connected with the basis, ground; Pulley is 4, and two that are positioned at the top are fixedly connected with the crossbeam of support, is positioned at that two of below pass through pulley base and ground is basic is fixedly connected.
Operating principle:
Motor is decelerated to the speed that needs through the VFC case, when motor drives cylinder and rotates through shaft coupling, is arranged on ring seal skewed slot on the cylinder along with cylinder rotates together; Because the roller in the skewed slot is fixedly connected on the top of clamping plate; The clamping plate lower part is fixed on the slide block, and the top and the bottom of clamping plate are fixed together with wire rope, so; When the sealing skewed slot on the cylinder promotes the roller moving linearly; Roller can drive the clamping plate moving linearly, and wire rope is moving linearly thereupon, and slide block also can only moving linearly on guide rail.When roller moved to sealing skewed slot end, roller just commutated, towards opposite-oriented movement.Cylinder whenever circles, and roller is just done the once reciprocating motion, and wire rope is also done the once reciprocating motion thereupon, pumps through pulley traction sucker rod, reaches the purpose of suction crude oil.
In whole motion process, because motor does uniform rotation, cylinder, wire rope are all made uniform motion, and the curve movement of sucker rod is pulse free at the uniform velocity, the application life that helps improving sucker rod.Complete machine does not have fragile part, can realize sturdy durable.
Energy-saving principle: because this invention realizes a machine gang pumping easily, can be that one drag two or drags four, promptly a covering device can carry out the oil pumping operation of two oil wells or four oil wells, so energy-saving effect is remarkable.
The utility model has not only solved the shortcoming that traditional beam type petroleum extractor structure is huge, operational shock is big, and has solved the shortcoming of high energy consumption, has realized simple in structure, compact; The pulse free that operates steadily, sturdy durable, realize a machine gang pumping easily; Practice thrift investment more than 1/3rd; Energy-saving effect reaches more than 50%, meets national requirements, and market prospects are very wide.
