Abstract
The invention discloses an advancing jack split pin remover, which comprises a manual hydraulic device (1), a sleeve (2), a hexagon nut (3), a hanging support (4), a pull rod (5), an adapter sleeve (6) and a folio clamping ring (7). One side of a jack in the manual hydraulic device (1) is provided with the hanging support (4); the hanging support (4) is arranged on a front connecting rod seat of a hydraulic bracket; the jack is provided with the sleeve (2) provided with a hole and the hexagon nut (3); the jack in the manual hydraulic device (1) and the lower end of the hanging support (4) are respectively provided with a center hole; and one end of the pull rod (5) which is provided with a screw thread is connected with the hexagon nut (3) by the center holes of the hanging support (4), the jack and the sleeve (2), while the other end is connected with the folio clamping ring (7) by the adapter sleeve (6). The advancing jack split pin remover has the characteristics of small volume, light weight, convenient carrying, simple operation, safety, reliability and high working efficiency and can be widely applied to the maintenance of the coal mine hydraulic bracket.
Description
Technical field:
The invention belongs to a kind of pin pulling out device, be specifically related to a kind of passing jack pin removal.
Background technology:
Hydraulic support is one of capital equipment of coal mining enterprise's fully-mechanized mining working, is one of critical component of hydraulic support and pass jack.Pass jack and break down when changing in the down-hole, the jack of dismounting passing earlier bearing pin could take out replacing.And when removing passing jack bearing pin, because the space is very narrow around passing the jack bearing pin, length is 10cm only, wide have only 6cm, the down-hole maintainer just bit by bit saws bearing pin with the hacksaw saw blade at present toward breaking, manual saw bow all can not use, and for up to more than 10 hours, and producer does not have good method to handle yet to this.This situation has increased down-hole maintainer's labour intensity greatly, has more seriously influenced the coal mining progress, has caused the decline of the output of raw coal.
Summary of the invention:
The invention solves that the work efficiency that exists in the hydraulic support maintenance replacing process is low, complicated operation, dangerous reliable problem.
The present invention is achieved through the following technical solutions: a kind of passing jack pin removal, comprise manual hydraulic device 1, cover 2, hex nut 3, hang bearing 4, pull bar 5, adapter sleeve 6, split collar 7, manual hydraulic device 1 is mainly by hand oil pump, jack and high-pressure oil pipe are formed, one side of the jack in the manual hydraulic device 1 is provided with hangs bearing 4, hanging bearing 4 is located on the front rod seat of hydraulic support, jack is provided with the cover 2 and the hex nut 3 of perforate, the lower end of jack that manual hydraulic device is 1 li and extension bearing 4 has centre bore, pull bar 5 threaded ends are by hanging the hole of bearing 4, the centre bore of jack is connected with hex nut 3 with the hole of cover 2, the other end of pull bar 5 by adapter sleeve 6 with split collar 7 and be connected, open collar 7 and pass the jack bearing pin and be connected.
The present invention compared with prior art has following beneficial effect: passing the jack pin removal, to have a volume little, in light weight, easy to carry, simple to operate, safe and reliable, and the characteristics that work efficiency is high can be widely used in the maintenance of coal mine hydraulic supporting.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
A kind of passing jack pin removal comprises manual hydraulic device 1, cover 2, hex nut 3, hangs bearing 4, pull bar 5, adapter sleeve 6, splits collar 7.Wherein manual hydraulic device is made up of hand oil pump, jack and high-pressure oil pipe etc.Hanging bearing 4 hangs on the front rod seat of hydraulic support, big face and hydraulic support front rod seat front are adjacent to, its center aligns with the very heavy bearing pin of passing center, the jack that manual hydraulic device is 1 li vertically is placed on to be hung on the bearing 4, and the centre bore, the hole of cover 2 of jack that pull bar 5 threaded ends pass adapter sleeve 6 successively, hang 1 li of hole, the manual hydraulic device of bearing 4 is connected with hex nut 3.The other end of pull bar 5 is connected with splitting collar 7 and pass the jack bearing pin by adapter sleeve 6.Twist good hex nut after guaranteeing each associated part center and the very heavy bearing pin of passing being consistent.
Method of operating
Check manual hydraulic device
1, checks oil mass
Counterclockwise open the unloader of handlance, the hydraulic oil in the jack is got back in the hydraulic cylinder of handlance, turn on hydraulic cylinder oiling flap, check oil mass, as oil discontented (should leave about 1/5 space in the hydraulic cylinder), the corresponding trade mark hydraulic oil of can annotating, hydraulic oil filters with 150 order screen packs.Put steadily the oil cylinder bottom, vertically stressed, must not overtravel work.
2, exhaust
After the manual hydraulic device hydraulic system has just assembled, often be mixed with air in oil pipe, the hydraulic cylinder, in order to make system's operate as normal; these air must be drained; method for exhausting is to unscrew the oiling flap, so that air is discharged in the hydraulic cylinder, manual pump is placed on the place higher than hydraulic cylinder; tighten unloader clockwise; press manual pump, make hydraulic cylinder piston extend out to range, open unloader again; make piston-retraction, get final product several times continuously.
3, check Pressure gauge
(1) Pressure gauge should be in " 0 " position when not having oil pressure fully.
(2) after unloader cuts out, to the jack pressurization, after all stretching out, piston pressurizes again two, three times, and gauge hand illustrates that at knee-action Pressure gauge and hydraulic tube are good.
It is reliable when errorless to check that each position connects, should evenly firmly press the manual hydraulic device oil hand pump, choose and pass very heavy bearing pin, pressure must not surpass 25MPa, when treating the about 10mm of the hydraulic cylinder piston swinging radius range left and right sides, opens unloader, make piston-retraction, twist good hex nut 3, continuously several times, till extracting the very heavy bearing pin of passing.
Claims (1)
1. passing jack pin removal, comprise manual hydraulic device (1), cover (2), hex nut (3), hang bearing (4), pull bar (5), adapter sleeve (6), split collar (7), manual hydraulic device (1) is by hand oil pump, jack and high-pressure oil pipe are formed, it is characterized in that: a side of the jack in the manual hydraulic device (1) is provided with hangs bearing (4), hanging bearing (4) is located on the front rod seat of hydraulic support, jack is provided with the cover (2) and the hex nut (3) of perforate, the lower end of the jack of manual hydraulic device (1) lining and extension bearing (4) has centre bore, the threaded end of pull bar (5) is by hanging the hole of bearing (4), the hole of the centre bore of jack and cover (2) is connected with hex nut (3), the other end of pull bar (5) by adapter sleeve (6) with split collar (7) and be connected, open collar (7) and pass the jack bearing pin and be connected.
