Description
Technical Field
The invention relates to the field of machinery, in particular to a main transmission structure of a large-scale multi-station mechanical press.
Background
In oil field production, oil extraction units often adjust production parameters of oil pumping wells according to production requirements, and stroke adjustment operation is an important item. According to the operating rule, the crank pin is taken out and then is installed in the corresponding stroke hole. The pumping unit service life is generally longer, because the crank pin is the metal connection, and long-time wind blows and drenches easy corrosion, so hardly dismantle. The existing method is that the hammer is knocked by a big hammer, time and labor are wasted, the hammer is difficult to detach if rust occurs, the stroke is adjusted by a crane, the cost is high, and a large safety risk exists.
Disclosure of Invention
In order to overcome the defects that manual knocking is needed and time and labor are wasted in the stroke adjusting operation of the existing oil pumping unit, the invention provides the light full-automatic stroke adjusting impact device of the oil pumping unit.
The technical scheme of the invention is as follows: a light full-automatic stroke adjusting impact device of a pumping unit comprises a shell, wherein an impact stop head is fixed inside the left end of the shell through a step, an impact hammer is arranged at the right end of the impact stop head, the right end of the impact hammer is connected with a hook claw of a hook machine, a spring is sleeved outside the hook machine, the right end of the hook machine is connected with two hydraulic cylinders in opposite directions, and ejector rods of the two hydraulic cylinders face to the two ends; the ejector rod of the right-end hydraulic cylinder is connected with a tail ejector head, and the right end of the tail ejector head is connected with a positioning block.
The pneumatic cylinder is left pneumatic cylinder and right pneumatic cylinder respectively, and the afterbody of two pneumatic cylinders contacts, and the ejector pin is towards both ends, passes through line connection magnetic valve on the left and right pneumatic cylinder respectively.
The impact blocking head is hollow inside, a boss is arranged outside the impact blocking head, and the boss is located on the right side of the step of the inner wall of the shell.
The spring is sleeved outside the hook machine, and two ends of the spring are respectively propped against the impact hammer and the hydraulic cylinder.
The invention has the following beneficial effects: by adopting the scheme, the impact device is arranged between the cranks at two sides, one end of the impact device is propped against the crank pin shaft at one side, the other end of the impact device is propped against the nut of the crank pin shaft at the other side, and the impact device is released after the spring is driven by the hydraulic cylinder to store energy, so that huge impact force is generated, and the crank pin shaft is detached. The stroke of the pumping unit is adjusted by adopting the device, manual hammering by a big hammer is not needed, time and labor are saved, the labor intensity of workers is greatly reduced, and the safe operation coefficient is improved.
Drawings
Fig. 1 is a schematic structural view of the present invention.
In the figure, 1-impact stop, 2-shell, 3-impact hammer, 4-hook machine, 5-spring, 6-left hydraulic cylinder, 7-right hydraulic cylinder, 8-tail top, 9-positioning block and 10-magnetic valve.
Detailed Description
The invention will be further described with reference to the accompanying drawings in which:
shown by figure 1, a light-duty full-automatic stroke adjustment impact device of beam-pumping unit, including casing 2, 2 left ends inside of casing is equipped with strikes fender head 1, is equipped with the step on the casing 2 inner wall, strikes fender head 1 outer wall middle part and is equipped with the boss, and the boss is located the step right side of casing 2 inner wall to make the step can block and strike fender head 1, make it can not deviate from by casing 2 in. The impact stopper 1 is made of brass, is hollow inside, and can be sleeved outside a crank pin shaft of the oil pumping unit to play a role in protecting the external threads of the pin shaft. The right end of the impact stop head 1 is provided with the impact hammer 3, the impact hammer 3 is made of brass, the operation of a crank pin shaft is avoided, the right end of the impact hammer 3 is connected with a hook claw of the hook machine 4 through a clamping groove, and when the hook machine 4 moves rightwards, the impact hammer 3 can be driven to move rightwards. 4 right-hand members of hook machine are equipped with the pneumatic cylinder, and the pneumatic cylinder is two, is left pneumatic cylinder 6 and right pneumatic cylinder 7 respectively, and the afterbody of two pneumatic cylinders contacts, and the ejector pin is towards both ends, can two-way power that provides. The hook machine 4 is connected with the ejector rod of the left hydraulic cylinder 6, the spring 5 is sleeved outside the hook machine 4, and two ends of the spring 5 respectively abut against the impact hammer 3 and the left hydraulic cylinder 6, so that the effects of energy storage and release can be achieved. The right hydraulic cylinder 7 is connected with a tail ejector 8 on the ejector rod, the right end of the tail ejector 8 is connected with a positioning block 9, and the positioning block 9 is identical to the crank pin nut in shape and can be sleeved on the crank pin nut. The left hydraulic cylinder 6 and the right hydraulic cylinder 7 are respectively connected with the magnetic valve 7 through pipelines, and the two hydraulic cylinders can be controlled by the magnetic valve 7 in one direction and can be fixed on a derrick foundation to form a firm operation platform.
When the stroke of the oil pumping unit needs to be adjusted, the device is placed between cranks on two sides, the impact stopper 1 is sleeved on a crank pin shaft on one side, the positioning block 9 is sleeved on a screw cap of a crank pin on the other side, the right hydraulic cylinder 7 is started, the ejector rod extends out in the right direction, the positioning block 9 is tightly pressed on the screw cap, and therefore the impact device is fixed. When the device stabilizes the back, start left pneumatic cylinder 6, make the hydraulic ram withdraw to the right, drive jump bit 3 through hook machine 4 and move to the right, compression spring 5 carries out the energy storage, and when spring 5 elasticity reached preset numerical value, left pneumatic cylinder 6 loosened, and spring 5 pops out to the left, jets out jump bit 3, hits the hitting at crank pin shaft tip to pull down the round pin axle.
