Abstract
A plate and crank combined device of an oil pumping unit. The main problem of current beam-pumping unit crank pin easily back knot and cause the machine of turning over, change crank pin inconvenient operation of solving. The method is characterized in that: one side of the crank (1) is provided with a square crank pin clamping groove (2), and a square crank pin (5) is connected in the crank pin clamping groove (2) through a bolt (7). The flat plate combined crank device of the oil pumping unit can reduce the loss of parts, improve the running stability of the crank, and is safe and labor-saving in operation when the crank pin is replaced.
Description
Technical Field
The utility model relates to the field of machinary, a dull and stereotyped crank device that combines of beam-pumping unit specifically says so.
Background
The beam-pumping unit is a main oil extraction machine type in China, adjustment of stroke parameters is a main means for achieving energy conservation and yield control of the pumping unit, and adjustment of the stroke parameters is to change the installation position of a crank pin on a crank, so that change of the rotation radius of the crank is achieved, and change of the stroke parameters is achieved.
At present, shaft sleeve connection is adopted between a crank and a crank pin, the number of components is large, the combination performance is difficult to guarantee, and the machine turning machine is often turned over due to the fact that a fastening nut of the crank pin is unscrewed or economic loss is caused due to the fact that a pin shaft and a taper sleeve are worn and replaced. And when adjusting the stroke and changing the crank pin, if the round pin bush takes place the corrosion then the unable dismantlement of manpower, need use multiple mechanical equipment, operating personnel intensity of labour is big, has very big potential safety hazard.
Disclosure of Invention
In order to overcome current beam-pumping unit crank pin easily to move back to detain and cause and turn over the machine, change the inconvenient not enough of crank pin operation, the utility model provides a dull and stereotyped crank device that combines of beam-pumping unit, this beam-pumping unit dull and stereotyped crank device that combines can reduce the parts loss, improves crank moving stability to it is laborsaving to change crank pin operation safety.
The technical scheme of the utility model is that: the utility model provides a dull and stereotyped crank device that combines of beam-pumping unit, includes the crank, open crank one side has square crank pin draw-in groove, has square crank pin through bolted connection in the crank pin draw-in groove.
The bottom surface of the inside of the crank pin clamping groove is provided with a positioning pile, and the crank pin is provided with a positioning hole matched with the positioning pile.
3 locating piles are arranged, locating holes matched with the locating piles are formed in the middle of the crank pin, semicircular limiting grooves are formed in two sides of each locating hole, and the limiting grooves are matched with the locating holes in the two sides.
The utility model discloses following beneficial effect has: owing to take above-mentioned scheme, the crank pin is square dull and stereotyped, with crank pin draw-in groove cooperation on the crank, replaces current crank pin and axle sleeve, makes the installation adjustment simpler, need not pound during the dismouting again and hit axle and axle sleeve, convenient operation. Meanwhile, the single shaft is matched and is changed into multi-bolt fastening, the structure is more stable, and the operation stability is improved.
Drawings
Fig. 1 is a front view of the present invention;
FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1;
FIG. 3 is a front view of the crank pin;
fig. 4 is a left side view of the crank pin.
In the figure, 1-crank, 2-crank pin clamping groove, 3-threaded hole, 4-positioning pile, 5-crank pin, 6-shaft, 7-bolt, 8-positioning hole and 9-limiting groove.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
shown by fig. 1 to 4, a dull and stereotyped crank device that combines of beam-pumping unit, including crank 1, 1 one side of crank is opened there is square crank pin draw-in groove 2, and 2 bottoms surfaces of crank pin draw-in grooves are the plane, and it has screw hole 3 to open on the plane, and crank pin draw-in groove 2 embeds there is square crank pin 5, and crank pin 5 passes through bolt 7 to be connected on screw hole 3, and 5 outside connecting axles 6 of crank pin. For making crank pin 5 conveniently connect, can be equipped with convex spud 4 on the inside bottom surface of crank pin draw-in groove 2, it has 4 matched with locating hole 8 with spud to open on crank pin 5, and during installation crank pin 5, overlaps locating hole 8 on spud 4, can realize crank pin 5 location. Furthermore, the spud 4 is 3, open at the middle part on the crank pin 5 has with spud 4 matched with locating hole 8, and semicircular spacing groove 9 has been opened respectively to 8 both sides of locating hole, and spacing groove 9 cooperatees with the locating hole 8 of both sides, and like this, when installation crank pin 5, two spacing grooves 9, a locating hole 8 cooperate with three spud 4 back respectively, and the screw hole on the crank pin 5 aligns with screw hole 3 on the crank 1 promptly, has increased location area, more makes things convenient for crank pin 5 to fix a position.
The device improves the existing shaft sleeve connection of the crank and the crank pin into flat plate butt joint, so that the installation and adjustment of the crank and the crank pin are simpler, time and labor are saved during stroke adjustment operation, the number of components is reduced, and the processing cost is reduced; the single shaft is matched and changed into a multi-bolt fastening position, so that the phenomenon that one nut is unscrewed to cause machine overturning is avoided.
