Abstract
The invention discloses a primary reduction gearbox with a separation and reunion function. The reduction gearbox consists of an input shaft I, an input shaft II, an output shaft and a hanging and reunion mechanism; the input shaft I and the input shaft II are connected with a crowned tooth coupler at a power end; pinions of the input shafts are meshed with a gear wheel of the output shaft; the pinions are fixed on a power input shaft; the gear wheel is sleeved on the power output shaft; and the power output shaft is connected with the gear wheel through the coupler. The mechanism can be controlled by using an air cylinder and can also be controlled manually. The hanging and reunion mechanism has a self-locking function and cannot be separated during load running. An air control device for hanging and reunion has signal display such as gear locking, and in-place hanging and reunion.
Description
Technical field
The invention belongs to the oil-well rig manufacturing field of equipment.
Background technique
At present, two, three of the general employings of domestic high-power petroleum well drilling reel cart in use or four AC motor are as power, and about driving by crown gear coupling, two gear reduction boxs come drive roller shaft through crown gear coupling again.When speed reducer is the primary speed-down case, because motor and speed reducer are to be rigidly connected, left and right speed reducer or running together, or stop together.Namely when AC motor all turned round, speed reducer all turned round; When monolateral AC motor running, the left and right speed reducer also all turns round and drives the running of another side AC motor.And if in the situation that in drilling process hook carry not quite, starting monolateral motor can satisfy the drilling well needs, and speed reducer all turns round and drive the running of another side AC motor, make like this rotary inertia of winch increase, increase starting time, and power increases, and causes unnecessary energy consumption.In addition due to the characteristics of high-power winch transmission, but the coupling between motor and speed reducer, speed reducer and drum shaft must not adopt the connecting mode of clutch, when if monolateral arbitrary or two motors break down in normal operation, the gear coupling that connects by crowned teeth can not Quick release and winch is shut down for a long time, may cause the generation of down-hole accident.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can control or manually control with cylinder, but and the extension on it close the primary speed-down case that mechanism has a kind of clutch of auto-lock function.
The present invention is achieved through the following technical solutions goal of the invention;
But a kind of primary speed-down case of clutch, speed reducer closes mechanism by input shaft I, input shaft II, output shaft and extension and forms, input shaft I, input shaft II are connected with the power end crown gear coupling, the small gear of input shaft is meshed with the gearwheel of output shaft, small gear is fixed on power input shaft, the gearwheel empty set is on pto＝power take-off, and power output is connected with gearwheel by coupling.
Speed reducer described in the present invention is primary speed-down, and the design of gears on output shaft is the empty set structure, and the extension that is designed for clutch at the other end of output shaft closes mechanism.
It is tooth clutch that extension described in the present invention closes mechanism, be made of external gear, internal gear, a side of gearwheel has little external gear, and external gear is fixed on pto＝power take-off, the internal gear empty set is on pto＝power take-off, and internal gear horizontally slips and is meshed with external gear, little external gear respectively afterwards.
Design proposal of the present invention is: the gearwheel on the output shaft of primary speed-down case is designed to the empty set structure, and the tooth-like extension that is designed for clutch at the other end of output shaft closes mechanism.The clutch of closing the winding machine speed reducer is hung in design.
It is tooth clutch that extension closes mechanism, be made of external gear, internal gear, a side of gearwheel has little external gear, and external gear is fixed on pto＝power take-off, the internal gear empty set is on pto＝power take-off, and internal gear horizontally slips and is meshed with external gear, little external gear respectively afterwards.
The advantage that the present invention compared with prior art has and effect:
1, the present invention is in the situation that the rig hook carries not quite, and when the running of monolateral AC motor, the another side speed reducer partly turns round and can't drive the running of another side AC motor, has shortened starting time, has reduced kinetic equation loss.
When 2, monolateral arbitrary or two motors of the present invention broke down, the another side motor still can drive the winch running, has effectively solved many problems such as high-power petroleum well drilling reel cart rapid-maintenance replacing, prevents the generation of down-hole accident.
3, the present invention can control by pneumatic, also can manually control, and be incorporated into the signal display apparatus such as position with self-locking device and backset, extension, and reliability is high.

Embodiment
As shown in the figure, but a kind of primary speed-down case of clutch, speed reducer closes mechanism 3 by input shaft I1, input shaft II4, output shaft 2 and extension and forms, input shaft I1, input shaft II4 are connected with the power end crown gear coupling, the small gear of input shaft is meshed with the gearwheel of output shaft 2, small gear is fixed on power input shaft, and the gearwheel empty set is on pto＝power take-off, and power output is connected with gearwheel by coupling.
Speed reducer in the present invention is primary speed-down, design of gears on output shaft 2 is the empty set structure, the extension that is designed for clutch at the other end of output shaft 2 closes mechanism 3, extension closes mechanism 3 and is tooth clutch, be made of external gear, internal gear, a side of gearwheel has little external gear, and external gear is fixed on pto＝power take-off, the internal gear empty set is on pto＝power take-off, and internal gear horizontally slips and is meshed with external gear, little external gear respectively afterwards.The extension that is used for clutch in the present invention closes mechanism 3 and can control with cylinder, also can manually control.Being used for hanging the air-control device that closes should have backset, extension to be incorporated into the signal demonstrations such as position.Extension closes mechanism 3 and has auto-lock function, does not throw off voluntarily during the on-load running.This mechanism can control with cylinder, also can manually control.
