Abstract

The utility model discloses a portable disassemble bracket, which is composed of a beam (1), a ring tab (2), a pull rod (3), a draw hook (4), a base (5), a connecting screw (7) and a connecting pin axis (7). The utility model is mainly suitable for the disassemble of axis parts with an axis journal over 60 mm. The ring tab (2), the pull rod (3) and the draw hook (4) are connected sequentially through the connecting pin axis (7), and are sleeved on the two ends of the beam (1) through the ring tab (2). The utility model can be matched with jacks in different types with stronger axial force, and can replace a <puller> and a press, so that the labor strength is reduced and the maintenance fee is lowered.

Description

Portable removal bracket

The utility model relates to a kind of improvement of axial workpiece dismounting used tool, specifically a kind of portable removal bracket.Mainly be applicable to the dismounting of the axial workpiece that axle journal 60mm is above.

At present, used " drawing horse " of dismounting of parts on shaft (as gear, bearing, wheel hub, shaft coupling etc.) is made up of jack and three claws.Because its structure and size limit, and are only applicable to the dismounting of the less part of axle journal.For the bigger parts on shaft of various heavy-duty machineries, particularly axle journal, powerless.People have to pull down spindle unit integral body, seek help from specialized factory.In specialized factory, people dismantle with large pressing machine, this method for dismounting, expense height, operation inconvenience.

It is a kind of simple in structure, easy to assembly that the purpose of this utility model is to provide, and energy and 30t, 50t, serial jack such as 100t, 160t cooperate, and is applicable to a kind of portable removal bracket of the axial workpiece dismounting of axle journal more than 60mm.This removal bracket and jack are used, and have stronger axial force, can substitute " drawing horse " and forcing press, reduce labor intensity.

The purpose of this utility model is achieved in that this portable removal bracket is made up of crossbeam, draw ring, pull bar, drag hook, base, connection bearing pin, attachment screw.Each parts all adopts carbon constructional quality steel and alloy steel material to form through machining and heat treatment manufacturing.It is rectangular-shaped that crossbeam is, and in crossbeam central bottom position 4 silk holes arranged, and matches with 4 holes of base one end, with attachment screw base and crossbeam is fixed together.Base can be made the series of products that highly differ as required.The draw ring upper end is " mouth " type, and the lower end is " U " type, and respectively there is a relative hole both sides, lower end.Stamp a hole respectively at two of pull bar, couple together with connecting the lower end of bearing pin with pull bar and draw ring, and be sleeved on the two ends of crossbeam by draw ring, pull bar can be made the series of products that length differs as required.The upper end of drag hook also is " U " type, and both sides also have a relative hole, with connecting bearing pin the upper end of drag hook and the lower end of pull bar is coupled together again, and portable like this removal bracket can complete.In concrete use, by regulating the distance between two draw rings on the crossbeam, the axial workpiece of applicable different-diameter size.Withstand on the base with jack one end, the other end withstands on the axle of axial workpiece, catches parts on shaft with drag hook, by the stroke variation of jack, can carry out the dismounting of axial workpiece.

The utility model has the advantages that: simple in structure, assembly and disassembly is convenient, the dismounting of the above axial workpiece of applicable axle journal 60mm.Be used with the jack of various series, have stronger axial force, can substitute " drawing horse " and forcing press, reduce labor intensity, reduce the machine maintenance expense.

Below in conjunction with accompanying drawing making of the present utility model is described in detail.

Accompanying drawing 1 is a front view of the present utility model

Accompanying drawing 2 is a left view of the present utility model

Make the utility model with reference to accompanying drawing 1, accompanying drawing 2.The utility model is to be made of crossbeam 1, draw ring 2, pull bar 3, drag hook 4, base 5, attachment screw 6, connection bearing pin 7.Crossbeam 1 is rectangular-shaped, adopts No. 45 forgings to make and forms.Length is controlled in the 400mm-1200mm scope, and thickness is between 80mm--100mm, and width is between 50mm--80mm.Bore in crossbeam 1 central bottom and to attack 4-M10 silk hole, match, be used for being connected with base 5 with 4 holes above the base 5.Draw ring 2, pull bar 3, drag hook 4, connection bearing pin 7 adopt the 40Cr material to forge respectively and form, and improve intensity by heat treatment again after the machining.At first respectively open a relative hole, respectively open a hole at the two ends of pull bar 3 again, respectively open a relative hole in both sides, drag hook 4 upper ends " U " at last, be convenient to connect with connecting bearing pin 7 in " U " of draw ring 2 lower ends type structure both sides; Pull bar 3 thickness are between 20mm--50mm, and length controlled is between 400mm--1200mm; Base 5 is cast with HT150 and is formed, and the centre is a cuboid, and its width is identical with pull bar 3 width, and two ends are rectangle, and area is big slightly, and the width of its end face is identical with the width of crossbeam 1, on an end face 4 apertures is arranged therein.With attachment screw 6 base 5 and crossbeam 1 are connected as a single entity, draw ring 2 is set in the two ends of crossbeam 1, with connecting bearing pin 7 pull bar 3 and draw ring 2 are linked together again, the other end at pull bar 3 links together pull bar 3 and drag hook 4 with connecting bearing pin 7 at last, and portable like this removal bracket can complete.

Claims

1, a kind of portable removal bracket, constitute by crossbeam (1), draw ring (2), pull bar (3), drag hook (4), base (5), attachment screw (6), connection bearing pin (7), it is characterized in that draw ring (2), pull bar (3), drag hook (4) link to each other successively with connecting bearing pin (7) respectively, and be set in the two ends of crossbeam (1) by draw ring (2).
