Description

Drawing out device for screw spike of concrete track sleeper

The utility model relates to a kind of railway concrete sleeper maintenance apparatus, the driver-extractor of especially manual concrete sleeper inefficacy screw spike.

The design service life of general railway concrete sleeper is 50 years, and screw spike shortens the application life of concrete pillow because influence of various factors premature failure often causes fastener not play a role.The screw spike failure cause mainly contains following several aspect: 1, the sled in the maintenance activity is pressed and is made the stressed excessive deformation failure that causes of screw spike; 2, screw spike not oiling for a long time makes the screw corrosion, or loses efficacy owing to the mechanical collision damaged screw makes railway spike; 3, train vibrations, track creeping and often rise, allocate for industry railway spike is damaged gradually; 4, because plate knot of ballast bed and rising soil, to make firm by ramming badly, the nut moment of torsion is excessive, makes the screw premature failure.In a word, railway spike lost efficacy and often takes place and be difficult to avoid.A concrete is rested the head on nearly 200 yuan, changes only 12 yuan on a railway spike, upgrades the too waste of concrete pillow because of railway spike loses efficacy, thereby the replacing screw spike makes the regeneration of concrete pillow comparatively suitable.But owing to lack proper tools, comparatively simple and crude, poor to the processing method of screw spike inefficacy disease, a lot of situations can not be handled, and cause circuit can not obtain on-call maintenance, cause rail creeping at present, and gauge can not keep even jeopardize traffic safety.

The processing of present stage to screw spike inefficacy disease mainly contains following method: 1, Yong Da Hammer is pounded firmly to withdraw from screw spike, and this method is very serious to the destruction of sleeper, and labour intensity is big, and operating efficiency is low.2, use long handle square opening spanner or long tongs to withdraw from railway spike, the method is still that labour intensity is big, efficient is low.3, adopt the bolt scavenger.This machine need have 220 volts of power supply coordinating operations, is to connect hollow boring bit with Churn drill to remove; The need that these facility are big for the anchoring deviation or screw is crooked are earlier sawed-off to be removed again, operation complexity, fault rate height, and need to block circuit, only be fit to change in flakes operation.4, adopt the high-frequency heating method to remove screw, though processing is comparatively convenient, laborsaving, the equipment manufacturing cost height needs electrical source of power, can not flexible Application.

The purpose of this utility model provides a kind of apparatus of easy manual removing inefficacy railway spike, and it can be fit to the use of the inefficacy railway spike of various situations, can significantly reduce labour intensity again, increases work efficiency.

The utility model screw spike driver-extractor is the apparatus of a multi-part combination, it comprises parts such as back timber, jack, stay column, crossbeam, supporting seat, support column, backplate, clamp body, gib, and wherein back timber, clamp body and two stay columns connect and compose a ladder-shaped frame; Crossbeam is a straight microscler rigid body, and its end is connected with supporting seat, and the other end and support column flexibly connect, and is connected with backplate below the support column; Lay a jack above the crossbeam, the top of jack withstand on back timber below; Have a notch on the clamp body of stay column bottom, notch is up big and down small, can insert a pair of gib that matches with this notch shape size.

The utlity model has following advantage: 1, easy to use, do not need power supply or other power source, both can rise in batch and pull out, changed screw spike, also be fit to remote or scattered maintenance activity.2, rising of various damage inefficacy screws being pulled out operation can both be suitable for.3, in light weight, upper and lower road is convenient, and loading and unloading flexibly.4, simple in structure, with low cost, be easy to processing and fabricating.5, easy operating, high efficiency does not influence driving.

Further specify structure of the present utility model below in conjunction with drawings and embodiments.

Fig. 1, Fig. 2 are structural representation of the present utility model;

Fig. 3 is the sectional view at clamp body position.

Concrete sleeper screw spike driver-extractor is made up of nut 1, taper liner 2, back timber 3, jack 4, pressure handle 5, stay column 6, crossbeam 7, supporting seat 8, support column 9, backplate 10, clamp body 11, gib 12.Its middle cross beam 7 is a straight girder steel, its end is welded with double iron supporting seat 8, the other end and support column 9 flexibly connect, support column 9 is a hollow cylinder, the termination that crossbeam 7 is corresponding with it can be inserted in the hollow cylinder, be welded with backplate 10 below the support column 9, crossbeam 7, supporting seat 8, support column 9 and backplate 10 constitute a complete bracing frame, the position on the shoulders of the shape of backplate 10 and concrete sleeper matches, an opening is arranged above the backplate 10, when backplate 10 blocked the jail mutually with the position on the shoulders of concrete pillow, the position of opening was corresponding to the screw spike place of concrete sleeper.Stay column 6 is two bolt of long stems, and beam 3 and 11 fens upper and lower strings of clamp body are on two stay columns 6, and stay column 6 tops have nut 1 and taper liner 2 fastening, and back timber 3, clamp body 11 and two stay columns 6 connect and compose a ladder-shaped frame as drawing mechanism.Have the trapezoidal notch of a up/down perforation above the clamp body 11, the trapezoidal notch both end sides has chute, two blocks of gibs 12 are a pair of iron blocks wide at the top and narrow at the bottom, its shape and size are corresponding with notch and chute thereof on the clamp body 11, can insert this trapezoidal notch simultaneously, two gibs, 12 corresponding medial surfaces have ratchet.

During use, unload the nut of railway spike earlier, take off fastener, then backplate 10 is aligned the portion on the shoulders of concrete pillow, supporting seat is seated on the rail, and bracing frame is just steadily being put, and the opening of backplate 10 aligns screw spike 13; Put clamp body 11 well, its notch also aligns railway spike 13, two blocks of gibs 12 is put into the both sides of notch railway spike 13; Jack 4 is located on the crossbeam 7, the top is below back timber 3 again, and plate fixed handle 5 rises the top, and jack-up back timber 3, stay column 6 drive clamp body 11 and rise, and two blocks of gibs 12 clamp railway spike 13.Pull pressure handle 5 continuously, can extract railway spike 13.The effect of backplate 10 is to make the screw edge of concrete pillow avoid damaged in collision.
