A kind of plus steel pipe skeleton flexible axle tamping pickaxe hose belongs to small-sized railway maintenance machinery industry.The technical solution of the utility model is: in the position overstriking of the dress vibration-damped handle of hose, overstriking position is surrounded by seamless steel pipe, several welding holes are processed on steel pipe, the helix tube tube core of manganese steel steel band coiling is all penetrated in seamless steel pipe, and are welded together to form solder joint with tube core at steel pipe welding hole；By after fiber knitted net or woven belt gluing with axis be in 450Angle uniform winding forms braiding layer, uniformly package inner rubber layer after cure outside braiding layer, inner rubber layer uniformly outer rubber layer after cure of the package containing steel wire again outside after vulcanization on steel pipe and tube core.Beneficial effect is: effectively overcoming tube core in existing flexible axle tamping pickaxe hose use and is easily detached from steel pipe, the drawbacks of being also easily broken at end and die bond, substantially increase the service life of flexible axle tamping pickaxe, it is novel in design, technique is advanced, structurally reasonable, remarkable benefit, safe and reliable.
Description
Technical field
It is mechanical that a kind of flexible axle tamping pickaxe of plus steel pipe skeleton with hose is related to small-sized railway maintenance, more particularly, to having made firm by ramming
The flexible axle tamping pickaxe of tiny fragments of stone, coal, etc. route railway roadbed.
Background technique
By the end of the year 2018, China railways mileage open to traffic more than 130,000 kilometers, wherein most be have tiny fragments of stone, coal, etc. route, including
All general fast railways and part high-speed railway.The railway roadbed for having tiny fragments of stone, coal, etc. route is made firm by ramming with tamping machine, it is flat to improve its track
Pliable and structural reliability is the important content of railway maintenance operation.Currently, there is small type railway of the tiny fragments of stone, coal, etc. route for ballast tamping
Maintenance of equipment is various tamping tools, wherein being most widely used especially with flexible axle tamping pickaxe.It generates vibration using stick is made firm by ramming
It is dynamic, overcome the frictional resistance between railway ballast, be allowed to relative motion and rearrange, lower gap will be rested the head on and filled up, to reach closely knit
The purpose of railway ballast, firm railway roadbed.The flexible axle of flexible axle tamping pickaxe transmits power, and hose connection power source and vibrating mechanism and protects
Flexible axle.Hose used in existing flexible axle tamping pickaxe, tube core is the helix tube of steel band coiling, at the overstriking position of dress vibration-damped handle
It is surrounded by steel pipe, the spiral tube core of steel band coiling penetrates one section of steel pipe (about 40mm), and in its end and steel-pipe welding.It is managed in use
Core is easily detached from steel pipe, and stress concentration is also easy to produce at steel pipe and die bond, is easily broken, seriously affects flexible axle tamping pickaxe
Service life becomes a prominent problem for perplexing small-sized railway maintenance machinery industry, and there is an urgent need to be improved, innovation is developed
A kind of Novel flexible tamping pickaxe hose, with adapt to that the tens of thousands of kilometers in the whole nation have that tiny fragments of stone, coal, etc. line tamping conserves there is an urgent need to.
Summary of the invention
The purpose of this utility model is exactly the drawbacks of overcoming existing flexible axle tamping pickaxe sebific duct, and a kind of plus steel pipe is developed in innovation
The flexible axle tamping pickaxe hose of skeleton.
The technical solution of the utility model is: in the position overstriking of the dress vibration-damped handle of hose, overstriking position is surrounded by seamless
Steel pipe processes several welding holes on steel pipe, the helix tube tube core of manganese steel steel band coiling is all penetrated in seamless steel pipe, and in steel
It is welded together to form solder joint with tube core at pipe welding hole；By after fiber knitted net or woven belt gluing with axis be in 450Angle uniformly twines
It is wound on steel pipe and tube core and forms braiding layer, uniformly package inner rubber layer after cure outside braiding layer, outside the inner rubber layer after vulcanization
Uniformly outer rubber layer after cure of the package containing steel wire again.
The beneficial effects of the utility model are: effectively overcome in existing flexible axle tamping pickaxe hose use tube core easily with
The drawbacks of steel pipe is detached from, and is also easily broken at end and die bond, substantially increases the service life of flexible axle tamping pickaxe, designs
It is novel, technique is advanced, structurally reasonable, remarkable benefit, safe and reliable.
Detailed description of the invention
Fig. 1 is that the structure of the utility model cuts open schematic cross-sectional view.
Fig. 2 is that steel pipe 2 penetrates tube core 1 and processes the schematic diagram of several welding hole 2-1 in Fig. 1.
Specific embodiment
The details and the course of work of the utility model are described in detail in conjunction with the attached drawing of the utility model embodiment.In hose
The position overstriking of vibration-damped handle is filled, overstriking position is surrounded by seamless steel pipe 2, several welding hole 2-1 is processed on steel pipe 2, manganese steel steel
Helix tube tube core 1 with coiling all penetrates in seamless steel pipe 2, and is welded together to be formed with tube core 1 at 2 welding hole 2-1 of steel pipe
Solder joint 3；By after fiber knitted net or woven belt gluing with axis be in 450Angle uniform winding forms braiding layer on steel pipe and tube core
4, uniformly package 5 after cure of inner rubber layer outside of braiding layer 4, the inner rubber layer 5 after vulcanization uniformly wraps up again outside contains steel wire 6
7 after cure of outer rubber layer.It is illustrated by taking internal diameter Φ 20mm long 2000mm hose as an example: in the portion of the dress vibration-damped handle of hose
Position mono- section of overstriking of 550mm, will process several welding hole 2-1, turns to internal diameter Φ with manganese steel steel band on the steel pipe 2 of long 550mm
The helix tube tube core 1 of 20mm, long 2100 mm all penetrate helix tube tube core 1 in seamless steel pipe 2 and in 2 welding hole 2-1 of steel pipe
Place is welded together to form solder joint 3 with tube core 1；By after fiber knitted net or woven belt gluing with axis be in 450Angle uniform winding exists
Braiding layer 4, uniformly package 5 after cure of inner rubber layer outside braiding layer 4, sulphur are formed on the steel pipe 2 of long 550mm and on remaining tube core 1
Uniformly outer rubber layer 7 after cure of the package containing steel wire 6 again outside inner rubber layer 5 after change, it is Φ that overstriking section outer diameter, which is made,
46mm, the hose that remaining outer diameter is Φ 36mm, 2100 mm of overall length, last both ends interception meet length requirement and novel add are made
The flexible axle tamping pickaxe hose of steel pipe skeleton.Through a long time scene uses, and tube core 1 is not detached from steel pipe 2 again, steel pipe 2 and tube core 2
Junction is not also broken again, it was demonstrated that this improvement attains the results expected, and perplexs the protrusion of small-sized railway maintenance machinery industry
Problem is resolved.The beneficial effects of the utility model are: effectively overcoming tube core in existing flexible axle tamping pickaxe hose use
The drawbacks of being easily detached from steel pipe, being also easily broken at end and die bond, substantially increase flexible axle tamping pickaxe uses the longevity
Life, it is novel in design, technique is advanced, structurally reasonable, remarkable benefit, safe and reliable.
