Abstract
The invention discloses a pipe taking method for replacing a pre-embedded sleeve of a railway concrete sleeper, which comprises steps: firstly, forming a longitudinal groove on the inner wall of the pre-embedded sleeve to be taken out; secondly, inserting a pipe taking tool matched with the groove formed on the inner wall of the sleeve into the sleeve, wherein a longitudinal ribbed protrusion on the pipe taking tool is fixedly meshed with the groove formed on the inner wall of the sleeve; and thirdly, rotating the pipe taking tool to take out the pre-embedded sleeve. The groove is formed in the pre-embedded sleeve, and the pipe taking tool matched with the groove is inserted into the sleeve to be fixedly meshed with the groove, so that the sleeve can be taken out by rotating the pipe taking tool with great effort. The whole pipe taking process is convenient and quick, and no track bed slab or concrete sleeper is damaged.
Description
Technical field
The present invention relates to a kind of tube side method of getting that railway concrete sleeper service sleeve is changed in the railroad maintenance construction that is used for.
Background technology
Development of High Speed Railway was very fast in recent years, a kind of quick, convenient, comfortable mode of transportation was provided for people's trip.What high-speed railway adopted all is gapless rail and non-fragment orbit, typically uses spring secures rail to sleeper in order to guarantee road-ability, even do not having to guarantee also on the monolithic railway roadbed of stone that train operation is smooth-going.
The rail of high-speed railway is fixed on concrete sleeper or the monolithic road bed board through fastener, and wherein rail fastening is embedded in wherein when concrete sleeper or monolithic road bed board are prefabricated with sleeve pipe.Sleeve pipe is that a kind of highstrenghtpiston processes, has certain intensity and elasticity, but sleeve pipe has certain useful life, needs periodic replacement to guarantee the security of operation of railway.More casing replacing needs to take out earlier originally to be embedded in the sleeve pipe in concrete sleeper or the road bed board; Usually adopt large-scale electric iron to melt original sleeve pipe; Prize then; So not only waste time and energy but also damage the sleeve pipe installing hole easily, installing hole needs to change whole sleeper or road bed board once damaging, thereby has increased cost widely.Therefore a kind of piping tool of conveniently getting is current urgent problem.
Summary of the invention
The technical problem that the present invention will solve provide a kind of easy to operate, change the tube side method of getting of railway concrete sleeper service sleeve quickly and easily.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of tube side method of getting of changing railway concrete sleeper service sleeve may further comprise the steps: 1, the inwall at service sleeve to be removed forms longitudinal fluting; 2, the piping tool of getting that the groove that forms on use and the internal surface of sleeve pipe is complementary inserts sleeve pipe, and this protruding engagement that forms with internal surface of sleeve pipe of vertical rib shape of getting on the piping tool is fixed; 3, piping tool is got in rotation, takes out service sleeve.
The said longitudinal fluting that forms at internal surface of sleeve pipe is three.
Said is the hot melt molding device at the employed instrument of service sleeve inwall formation longitudinal fluting to be removed, and operating temperature is 600 ℃.
Beneficial effect of the present invention: because the present invention is through forming groove in service sleeve, the piping tool of getting that will match then inserts in the sleeve pipe and fixes with engagement, and firmly rotation is got piping tool and just can sleeve pipe be taken out; The whole pipe process convenient of getting is quick, does not destroy bed board or concrete sleeper.
The specific embodiment
Below in conjunction with embodiment the present invention is specified.Should be understood that said embodiment only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
A kind of tube side method of getting of changing railway concrete sleeper service sleeve of the present invention may further comprise the steps: 1, the inwall at service sleeve to be removed forms longitudinal fluting; 2, the piping tool of getting that the groove that forms on use and the internal surface of sleeve pipe is complementary inserts sleeve pipe, and this protruding engagement that forms with internal surface of sleeve pipe of vertical rib shape of getting on the piping tool is fixed; 3, piping tool is got in rotation, takes out service sleeve.
The longitudinal fluting that forms at internal surface of sleeve pipe is preferably three.Employed instrument is the hot melt molding device, and operating temperature is 600 ℃.This hot melt molding device comprises shaped device, heater and operating grip, and shaped device, heater and operating grip are connected through bolt.Shaped device foremost is the cylinder that front end has tapering, and rib shape is protruding longitudinally to be provided with three around it, and rib shape convexity along the circumferential direction equidistantly distributes.
After hot melt molding device energising work; Can make the temperature of the shaped device that is connected with heater be raised to 600 ℃ operating temperature soon, at this moment on internal surface of sleeve pipe, melt and corresponding three grooves of three prismatic of shaped device through the operating grip of pushing the hot melt molding device.Then the hot melt molding device is taken out from sleeve pipe; Insertion matches gets piping tool; Because three prismatic of getting on the piping tool are fixed with three engagement on the internal surface of sleeve pipe, just so firmly rotating can be quickly and easily with the sleeve pipe taking-up, and does not destroy bed board or concrete sleeper.
Claims (3)
1. the tube side method of getting of changing railway concrete sleeper service sleeve is characterized in that, may further comprise the steps: (1) forms longitudinal fluting at the inwall of service sleeve to be removed; (2) piping tool of getting that the groove that forms on use and the internal surface of sleeve pipe is complementary inserts sleeve pipe, and this protruding engagement with internal surface of sleeve pipe formation of vertical rib shape of getting on the piping tool is fixed; (3) piping tool is got in rotation, takes out service sleeve.
2. a kind of tube side method of getting of changing railway concrete sleeper service sleeve as claimed in claim 1 is characterized in that, the said longitudinal fluting that forms at internal surface of sleeve pipe is three.
3. according to claim 1 or claim 2 a kind of tube side method of getting of changing railway concrete sleeper service sleeve is characterized in that, said to form the employed instrument of longitudinal fluting at service sleeve inwall to be removed is the hot melt molding device, and operating temperature is 600 ℃.
