The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.But what those skilled in the art should know is to the invention is not restricted to the listed specific embodiment, as long as spirit according to the invention all should be included in protection scope of the present invention.
Service machine hydraulic wireline winch control setup of the present invention; Comprise HM Hydraulic Motor, epicyclic reduction gear, power-transfer clutch, cylinder, drum shaft; Be installed with cylinder on the drum shaft, different according to power-transfer clutch and epicyclic reduction gear installation site are divided into built-in and external two kinds of versions.
First technical scheme of service machine hydraulic wireline winch control setup of the present invention is built-in (referring to accompanying drawing 1), and power-transfer clutch 4 and power-transfer clutch 5 are positioned at the middle part of cylinder 3, and be coaxial with drum shaft 6.The outside of power-transfer clutch 4 is equipped with epicyclic reduction gear 2, HM Hydraulic Motor 1 successively; The input shaft of epicyclic reduction gear 2 is connected with HM Hydraulic Motor 1, and output shaft is connected with drum shaft 6, and power-transfer clutch 4 is installed on the output shaft of epicyclic reduction gear 2.The outside of power-transfer clutch 5 is equipped with epicyclic reduction gear 7, HM Hydraulic Motor 8 successively.The input shaft of epicyclic reduction gear 7 is connected with HM Hydraulic Motor 8, and output shaft is connected with drum shaft 6, and power-transfer clutch 5 is installed on the output shaft of epicyclic reduction gear 7.Power-transfer clutch 4, power-transfer clutch 5, epicyclic reduction gear 2, epicyclic reduction gear 7 are arranged in the endoporus of cylinder 3.Built-in service machine hydraulic wireline winch control setup compact conformation, axial dimension is little, is convenient to be installed on the workover rig chassis.
Another technical scheme of service machine hydraulic wireline winch control setup of the present invention is external (referring to an accompanying drawing 2), is installed in that a side of cylinder 3 is equipped with power-transfer clutch 4 on the drum shaft 6, and opposite side is equipped with power-transfer clutch 5.Power-transfer clutch 4 outsides are equipped with epicyclic reduction gear 2, HM Hydraulic Motor 1, and the input shaft of epicyclic reduction gear 2 is connected with HM Hydraulic Motor 1, and the output shaft end of epicyclic reduction gear 2 is equipped with gear and is installed in the gear mesh on the drum shaft 6.Power-transfer clutch 5 outsides are equipped with epicyclic reduction gear 7, HM Hydraulic Motor 8, and the input shaft of epicyclic reduction gear 7 is connected with HM Hydraulic Motor 8, and the output shaft end of epicyclic reduction gear 7 is equipped with gear and is installed in the gear mesh on the drum shaft 6; Rotate through gear mesh head roll 3.The power-transfer clutch of external service machine hydraulic wireline winch control setup is installed in the cylinder outside, is convenient to control and replacing.
In above-mentioned 2 technical schemes, the reduction ratio of epicyclic reduction gear 2 is less than the reduction ratio of epicyclic reduction gear 7; According to well workover construction operation needs, the model of epicyclic reduction gear 2 is JH3, the JQ13 of the model of epicyclic reduction gear 7, and the reduction ratio of epicyclic reduction gear 2 can be 6～11, the reduction ratio of epicyclic reduction gear 7 can be 23～28.Power-transfer clutch 4, power-transfer clutch 5 operation of modulated pressure motor 1, HM Hydraulic Motor 8 respectively, power-transfer clutch can be selected the wet type lamella clutch for use.
Epicyclic reduction gear 2 reduction ratios of service machine hydraulic wireline winch control setup of the present invention are less than epicyclic reduction gear 7 reduction ratios; Power-transfer clutch 4 is identical with power-transfer clutch 5 structures, but control respectively.When power-transfer clutch 4, when power-transfer clutch 5 is thrown off simultaneously, service machine winch drum 3 rotates freely, and under the effect of load, makes the hook of service machine transfer fast.Hang when power-transfer clutch 4 close, when power-transfer clutch 5 is thrown off, HM Hydraulic Motor 1 drives epicyclic reduction gear 2 rotations, drives the drum shaft 6 and cylinder 3 fast rotational of winch, realize the service machine hook little load fast lifting, transfer.When that power-transfer clutch 4 is thrown off, power-transfer clutch 5 is hung is fashionable, HM Hydraulic Motor 8 drives epicyclic reduction gears 7 rotations, drives winch drum shaft 6 and the rotation of cylinder 3 middling speeds, realizes that service machine hook heavy load promotes, transfers.When power-transfer clutch 4, that power-transfer clutch 5 is hung simultaneously is fashionable; HM Hydraulic Motor 1, HM Hydraulic Motor 8 are exported simultaneously; Drive winch drum shaft 6 and cylinder 3 low speed rotation through epicyclic reduction gear 2, epicyclic reduction gear 7, high pulling torque output is used for service machine and implements operation in the unfreezing operating mode.
It should be noted that the foregoing description is example and unrestricted the present invention, those skilled in the art can design a lot of alternate embodiments and not break away from the claim scope of this patent.
