Abstract
A wrench for preparing a nut of a crank pin of a pumping unit. The main problem of solving current crank pin dismantlement and need two people to accomplish, operational safety is poor. The method is characterized in that: the utility model discloses a crank pin, including nut (2), hexagonal sleeve (3), internal gear (4), star gear (6) outside and external gear (8), nut (2) outside cover has hexagonal sleeve (3), and hexagonal sleeve (3) right-hand member is connected with internal gear (4), and internal gear (4) outside and star gear (6) meshing, star gear (6) outside and external gear (8) meshing, external gear (8) right-hand member is equipped with tip baffle (11), connects on crank pin (1) through bolt (9) on tip. Adopt this beam-pumping unit crank pin nut to beat and equip spanner and dismantle the crank pin, only need alone can accomplish, the operation is safe laborsaving.
Description
Technical Field
The utility model relates to an oil field, a beam-pumping unit crank pin nut is equipped with spanner specifically says so.
Background
During the operation of the pumping unit, the crank pin has damaged parts due to various reasons, and during maintenance or replacement, the crown nut needs to be removed and then the pin needs to be removed. However, when the sleeve is damaged, the pin lock plate rotates to prevent the crown nut from being removed, which results in the failure of the crank pin to replace and maintain. At present in order to solve this problem, when going into the well and maintaining the crank pin, need two people to accomplish jointly, use the fixed crank pin of spanner in the beam-pumping unit crank outside alone, another individual uses the spanner to dismantle crank pin fastening nut in the crank inboard, needs two people to cooperate unanimously, and the security of operation is relatively poor.
SUMMERY OF THE UTILITY MODEL
Need two people to accomplish, the poor not enough of operational safety in order to overcome current crank pin dismantlement, the utility model provides a beam-pumping unit crank pin nut is equipped with the spanner, adopts this beam-pumping unit crank pin nut to be equipped with the spanner and dismantles the crank pin, only needs alone to accomplish, and the operation is safe laborsaving.
The technical scheme of the utility model is that: the utility model provides a spanner is equipped with to beam-pumping unit crank pin nut, includes the crank pin, crank pin external connection has the nut, the outside cover of nut has the hexagonal sleeve, and hexagonal sleeve right-hand member is connected with the internal gear, the internal gear outside with the meshing of planet gear, the outside and the external gear meshing of planet gear, the external gear right-hand member is equipped with the tip baffle, through bolted connection on the crank pin on the tip baffle.
And a plurality of hook wrench holes are formed in the outer wall of the hexagonal sleeve.
An inner baffle is sleeved outside the inner gear, three pin shafts are connected to the inner baffle, each pin shaft is connected with a star gear, and an outer baffle is arranged outside the star gears.
The utility model discloses following beneficial effect has: by adopting the scheme, the wrench improves the torque by reducing the transmission ratio according to the principle of gear transmission, and the transmission ratio of the two-stage gear transmission is 1:4, so that the torque can be increased by a factor of 4. Therefore, when the crank pin is disassembled, the wrench is installed on the crank pin nut, a small force is applied to the hexagonal sleeve, the crank pin nut can be disassembled, only one can be used for operation, and the operation is safe and labor-saving.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a sectional view taken along a-a in fig. 1.
In the figure, 1-crank pin, 2-nut, 3-hexagonal sleeve, 4-internal gear, 5-internal baffle, 6-star gear, 7-external baffle, 8-external gear, 9-bolt, 10-pin shaft and 11-end baffle.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
by figure 1, fig. 2, a spanner is equipped with to beam-pumping unit crank pin nut, including crank pin 1, 1 external connection of crank pin has nut 2, 2 outside covers of nut have hexagonal sleeve 3, open on the 3 outer walls of hexagonal sleeve have a plurality of eave tile spanner hole, the inside hexagonal cover that is with 2 matched with of nut of 3 left ends of hexagonal sleeve, 3 right-hand members of hexagonal sleeve are connected with internal gear 4, and 4 left ends of internal gear are in the same place with 3 welding of hexagonal sleeve, therefore hexagonal sleeve 3 can drive internal gear 4 rotations. 4 outside covers of internal gear have interior baffle 5, are connected with three round pin axle 10 on the interior baffle 5, and round pin axle 10 is on a parallel with 1 axis direction of crank pin, follows the circumference equipartition entirely, all connects a star gear 6 on every round pin axle 10, and three star gear 6 all meshes with internal gear 4, and internal gear 4 is 1 with star gear 6's drive ratio: 2. an outer baffle 7 is arranged outside the star gear 6, and pin shaft holes are also formed in the outer baffle 7, so that the outer baffle 7 is sleeved on the three pin shafts 10. The external gear 8 is sleeved outside the planetary gear 6, the planetary gear 6 is meshed with the external gear 8, and the transmission ratio of the planetary gear 6 to the external gear 8 is 1: 2. the right end of the outer gear 8 is provided with an end baffle 11, and the end baffle 11 is connected to the crank pin 1 through a bolt 9.
When the hexagonal socket is used, the hexagonal socket 3 and the inner gear 4 are welded together, the hexagonal socket 3 is sleeved on the crank pin nut 2, the star gear 6 and the outer gear 8 are installed, the inner side of the star gear 6 is meshed with the inner gear 5, and the outer side of the star gear is meshed with the outer gear; finally, the bolt 9 is inserted through the end stop 11 into the threaded bore of the crank pin 1 and tightened. The hook wrench or the chain buckle wrench is used for rotating the hexagonal sleeve 3 anticlockwise, the hexagonal sleeve 3 drives the inner gear 4, the inner gear 4 drives the star gear 6, and the inner gear 4 and the star gear 6 are externally tangent gears, so that the moving directions are opposite. The star gear 6 drives the external gear 8, and the star gear 6 and the external gear 8 are internally tangent gears, so that the motion directions are the same. The external gear 8 carries the end baffle 11 and its reaction force is loaded on the crank pin nut 2 since the end baffle 11 is already fixed to the crank pin 1. Because the transmission silk between internal gear 4 and planetary gear 6 is 1: 2, the transmission ratio between the planetary gears 6 and the external gear 8 is also 1: 2, the transmission ratio of the whole device is 1:4, so that the operation can be completed by using a pipe wrench of 1 meter in the past, and only 300 chain-lock wrench or hook wrench is needed to complete the operation, thereby reducing the labor intensity of operators and ensuring safer operation.
