Abstract

The utility model aims to provide a novel fluid coupling withdrawal tool, can efficiently solve the problems that a coupling cannot be dismantled, wastes a great amount of time and labor, and has a strong impact on the normal safe production of the coal face, and provides a technical scheme as follows: the utility model includes an end head, a top thread rod and a nut; the front end (the right end) of the top thread rod is an input shaft of a speed reducer, and the nut is arranged at the rear end (the left end); a through hole in linear communication with the middle of the top thread rod and the middle of the nut is formed at the center of the end head of the input shaft of the speed reducer; a mandril is arranged in the through hole; a fixed framework is arranged at the rear end of the top thread rod; an oil cylinder is arranged in the fixed framework to bear against the mandril; and the fluid coupling can be dissembled from the speed reducer through pressurizing and replacing mandrils with different lengths. In equipment maintenance, the utility model has convenient, easy and efficient performance, reduces labor and time, improves efficiency, increases safety factor and plays good effect, therefore, the popularization and the application has good economic and social benefits.

Description

Novel fluid-flywheel clutch extracting tool

One, technical field

The utility model relates to extracting tool, particularly a kind of novel fluid-flywheel clutch extracting tool.

Two, background technology

Fluid-flywheel clutch (hydrodynamic coupling) is a kind of widely used hydraulic transmission component.Fluid-flywheel clutch has flexible transmission, slows down impact, isolates the function of torsional oscillation, can prolong the device start time, reduces the device start electric current, and the overload protection motor makes the power-equipment light-load starting, has solved the difficult problem that the transporting equipment heavy duty starts.And the functions such as sharing of load between the balanced multiple motors of energy.Particularly comprehensive mechanical coal mining working face in colliery has obtained extensive use in every profession and trade transportation system.In service work during for the outside framework oil seal of checking, change fluid-flywheel clutch or reducer input shaft place and bearing, must pull down fluid-flywheel clutch from power shaft, by the key connecting interference fit, manufacturer is equipped with special-purpose jackscrew thick stick extracting tool between fluid-flywheel clutch and the reducer input shaft.In dismounting coupling device process, often occur not tearing open or push rod stripped thread and situation about can't dismantle expends a large amount of time and manpower for this reason, have a strong impact on coal-face and normally keep the safety in production.

The special-purpose jackscrew thick stick extracting tool dismounting coupling device that uses present manufacturer to be equipped with, situation of difficult in the time of the dismounting fluid-flywheel clutch can occurring, according to the field stripping situation analysis, must rotate the jackscrew thick stick when using jackscrew thick stick extracting tool, withstand the reducer input shaft termination up to the jackscrew thick stick, afterburning then rotation jackscrew thick stick makes fluid-flywheel clutch go out to inner rotary along the hand of spiral of jackscrew thick stick.But in real work,, at this moment as easy as rolling off a logly cause between the screw thread interlock mutually and can't rotate,, can make the screw thread stripped thread so that the jackscrew thick stick is scrapped as firmly excessive because screw thread will bear huge longitudinal force when generation relatively moves.Scuffing when therefore the jackscrew thick stick rotates is its main cause, also is puzzlement maintenance key consuming time, so, how to solve its technical barrier?

Three, utility model content

At above-mentioned situation, for overcoming the defective of prior art, the purpose of this utility model is to provide a kind of novel fluid-flywheel clutch extracting tool, can effectively solve coupling device does not tear open maybe and can't dismantle, expend plenty of time and manpower, have a strong impact on the problem of the normal safety in production of coal-face, the technical scheme of its solution is, the utility model comprises the termination, jackscrew bar and nut, jackscrew bar front end (right-hand member) is a reducer input shaft, there is nut rear end (left end), and center, reducer input shaft termination has and the jackscrew bar, the through hole of the linear connection of nut middle straight has push rod in the through hole, the jackscrew rod rear end has fixed frame, be equipped with oil cylinder in the fixed frame and withstand push rod, the push rod by pressurization and replacing different length presses down fluid-flywheel clutch from decelerator.The utility model has performances such as easy, easy-to-use, efficient in overhaul of the equipments, reduced manpower and time, has improved efficient, has increased safety coefficient, has played good effect, and it is applied, and has good economic and social benefit.

Four, description of drawings

Accompanying drawing is a structural profile user mode front view of the present utility model.

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is done detailed explanation.

Shown in accompanying drawing, the utility model comprises jackscrew bar and nut, jackscrew bar 10 front ends (right-hand member) are reducer input shafts 3, there is nut 1 rear end (left end), and center, reducer input shaft termination has and jackscrew bar, the linear through hole that is communicated with 4 of nut middle straight, and push rod 6 is arranged in the through hole 4, the jackscrew rod rear end has fixed frame, be equipped with oil cylinder 5 in the fixed frame and withstand push rod, by pressurization with change the push rod of different length, fluid-flywheel clutch 2 is pressed down from decelerator.

In order to guarantee result of use, said fixed frame fixedly is made up of through nut two left riser 7a, right riser 7b and two horizontal last screw rod 8a, following screw rod 8b, last screw rod 8a, following screw rod 8b laterally place left riser 7a, right riser 7b two ends, form quadra, right riser 7b vertically is contained on jackscrew bar 10 rear ends; On two left risers, the right riser each porose 9; Said oil cylinder 5 one ends are fixed in the fixed frame by right riser hole, and hole, nut that push rod 6 passes on the right riser 7b link to each other with oil cylinder.

During concrete enforcement, at first former special-purpose jackscrew thick stick extracting tool is made a call to an open-work from the center, termination,, and on two block plates, make a suitable special-purpose leading screw respectively and pass hole 9 with fixed oil cylinder again with fixed frame of two block plates and two screw rods compositions.Reprocess the round steel that several segment length do not wait in addition and make push rod 6, put into special-purpose leading screw and withstand on the reducer input shaft 3.In framework, put into oil cylinder 5, and connect good fluid pressure line, withstand push rod 6, by continuous pressurization with change the push rod of different length, fluid-flywheel clutch 2 is pressed down from decelerator.

During use: make fluid-flywheel clutch become as a whole by threaded engagement, in frame structure, put into suitable jack then, the steel bushing of fluid-flywheel clutch on framework that is connected as a single entity transferred to by push rod with steel bushing on the framework.

The utility model has performances such as easy, easy-to-use, efficient in overhaul of the equipments.Through incomplete statistics, the utility model extracting tool after the improvement is saved time about 4 hours than former instrument, has significantly reduced manpower and time, has improved efficient, has increased safety coefficient, has played good effect.Of the present utility model applying has good economic and social benefit.
