Abstract
The utility model provides a novel construction sleeve pipe, which comprises steel plates, a steel pipe, a screw rod, an inner screw nut and an outer screw nut, wherein the steel plates are welded at the two ends of the steel pipe, a through hole is formed in the steel plate arranged at one end of the steel pipe, the inner screw nut is welded at the inner side of the through hole, the outer screw nut is welded at the outer side of the through hole, and the screw rod extends into the inside of the steel pipe through the through hole and is fixedly arranged on the steel pipe through the outer screw nut. The novel construction sleeve pipe has the advantages that the screw nuts are simultaneously arranged at the inner side and the outer side of the steel pipe for positioning and fixing the screw rod, so that the stability of the screw rod is improved; when the sleeve pipe is not used, most parts of the screw rod can extend into the steel pipe, and a clamping screw nut is rotated, so that the storage of the sleeve pipe can be completed, and since the falling and the damage of the screw rod are effectively prevented, the service life of the sleeve pipe is prolonged.
Description
Technical field
The utility model relates to track traffic maintenance tool field, is specially a kind of novel construction casing.
Background technology
In recent years, after railway the sixth speed-up, having there are great changes in circuit, the track switch equipment of increasing railway, work business, to maintenance, brings many difficulties.Track switch is the integral body of an interlock, and it is relating to car business, work business, ，Yi Ge department of a plurality of department of telecommunication and signaling branch makes a fault, and gently affects road speed, heavy cut off traffic, and will bring direct losses to transportation.In recent years along with the continuous upper track of acclerating road switch is applied, its routine servicing and maintenance just become a basic job in track division maintenance organization system, acclerating road switch is the basis of improving railway transportation, yet the sleeve pipe as one of maintenance tool, because there is no stationary positioned device, cover male union easily comes off, in use because the tension of exerting oneself easily causes in cover male union retraction sleeve pipe, all operations need to restart, affect construction speed, even affect train operation, and sleeve pipe corrosion-resistant.
Utility model content
The technical problem that the utility model solves is to provide a kind of novel construction casing, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of novel construction casing, comprise steel plate, steel pipe, screw rod, inner nut and outer nut, wherein, described Plate Welding is at the two ends of steel pipe, on the steel plate of described steel pipe one end, have through hole, described through hole inner side is welded with inner nut, and described through hole outside is welded with outer nut, described screw rod stretches into steel duct by through hole, and is fixed on steel pipe by outer nut.
In the utility model, on described through-hole wall, be provided with screw thread.
In the utility model, on described screw rod, be also provided with binding nut, binding nut coordinates outer nut and inner nut to fix and location screw rod.
In the utility model, on described steel pipe, be coated with anticorrosive coat, can effectively prevent that steel pipe from getting rusty, be corroded, improve the application life of steel pipe.
In the utility model, before use, first according to construction requirement, screw rod is stretched into steel duct certain distance by through hole, then rotary screw is tightened inner nut, again tightens outer nut, last rotating clamp jack panel, thereby complete screw rod location with fixing, improve the stability of screw rod; When not using sleeve pipe, screw rod major part can be stretched into steel pipe, rotating clamp jack panel, can complete taking in of sleeve pipe, effectively prevents dropping and damaging of screw rod.
Beneficial effect: the utility model, by with outside, nut is set in steel pipe inner side simultaneously, positions and fixes screw rod, improves the stability of screw rod; When not using sleeve pipe, screw rod major part can be stretched into steel pipe, rotating clamp jack panel, can complete taking in of sleeve pipe, effectively prevents dropping and damaging of screw rod, improves the application life of sleeve pipe.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of novel construction casing referring to Fig. 1, comprise steel plate 1, steel pipe 2, screw rod 3, inner nut 4 and outer nut 5, wherein, described steel plate 1 is welded on the two ends of steel pipe 2, on the steel plate 1 of described steel pipe 2 one end, have through hole, described through hole inner side is welded with inner nut 4, and described through hole outside is welded with outer nut 5, described screw rod 3 stretches into steel pipe 2 inside by through hole, and is fixed on steel pipe 2 by outer nut 5.
In the present embodiment, on described through-hole wall, be provided with screw thread.
In the present embodiment, on described screw rod 3, be also provided with binding nut 6, binding nut 6 coordinates outer nut 5 and 4 pairs of screw rods of inner nut 3 to fix and location.
In the present embodiment, on described steel pipe 2, be coated with anticorrosive coat, can effectively prevent from that steel pipe 2 from getting rusty to be corroded, improve the application life of steel pipe 2.
In the present embodiment, before use, first according to construction requirement, screw rod 3 is stretched into the inner certain distance of steel pipe 2 by through hole, then rotary screw 3 is tightened inner nut 4, again tightens outer nut 5, last rotating clamp jack panel 6, thereby complete screw rod 3 location with fixing, improve the stability of screw rod 3; When not using sleeve pipe, screw rod 3 major parts can be stretched into steel pipe 2, rotating clamp jack panel 6, can complete taking in of sleeve pipe, effectively prevents dropping and damaging of screw rod 3.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
