Description

Split type internal combustion single track tamping tool

One: technical field:

The utility model belongs to the railway maintenance mechanical field.

Two: background technology:

The railway that China is more than 70,000 kilometer is the ballastless track except that the Expressway between Beijing and Tianjin railway of just opening operation, and all the other are ballasted track.Tamping operation to railway roadbed under the sleeper is an important step of railway maintenance construction, and is especially even more important to the railway roadbed that hardens.Only need make the railway roadbed under the side rail in the time of many in addition firm by ramming.At present, the maintenance machinery that railway roadbed makes firm by ramming that also is not suitable for hardening.For emergent, the internal combustion list pick on broken damage road surface is used for the situation that railway is made the railway roadbed that hardens firm by ramming temporarily in the handlebar HIGHWAY MAINTENANCE.But the gasoline engine of this single pick is fixed in the top of single pick, and power section is an one with making part firm by ramming, and gasoline engine turns round under vibrational state during operation, early stage well damage, even scrap in batch.

Three: summary of the invention:

The purpose of this utility model will design a kind of power section and make part firm by ramming and be divided into two bodies, convenient mobile construction, can make the diesel tamping machine that side plate is tied railway roadbed safely and efficiently firm by ramming.

The technical solution of the utility model is: power source and tamping pickaxe are divided into two bodies, are partly coupled together by the flexible axle flexible pipe.Gasoline engine is fixed on the walking frame, and the clutch through the driving pulley groove is arranged on the shell, V-belt, driven pulley are with on power distribution to two output shaft.Output shaft places in the bearing support that is fixed on walking frame, and an end cooperates with driven pulley, and the other end has the endoporus of band ratchet, is used for being connected with the flexible axle plug of flexible axle one end.Bearing support is equipped with head, and head is connected with the coupling head of flexible pipe one end, connects the back and pins with joint handle, and the square plug of the flexible axle other end injects in the square hole that connects axle, gives tamping pickaxe with transmission of power.When injecting terminal pad, the snap joint of the flexible pipe other end pushes down with gland.Connect the axle with gear shaft to be threaded.Gear shaft is supported on the interior supplementary bearing of body and meshes with driven gear.Being processed with off-centre on the driven gear is connected with connecting rod.The other end of connecting rod is equipped with columniform slide block, and slide block is contained in the slideway.On the slideway one end boss cushion pad is housed.Slideway has slip case outward, last and body, and following and connection seat is linked together by two studs, nuts.Be processed with square hole on the connection seat and linking fixture block and rubber pad.Be processed with the four directions on the stamp stem, inject in the Connection Block and block the pick ballast tamping of front end with fixture block.

The beneficial effects of the utility model are: power source and tamping pickaxe are divided into two bodies, avoid gasoline engine to turn round under vibrational state, have alleviated the harm of gasoline engine waste gas to the operator, and be in light weight, long, hommization of life-span; Vibration parameters adapts to the operating mode needs of making the railway roadbed that hardens firm by ramming, and the action direction of amplitude and exciting force is consistent with the desired direction of closely knit ballast aggregate, and compliance is strong, the production efficiency height, and tamping result is good; Insulation is reliable, and vibration damping is good, and online use can not influence line signal yet, and the road is convenient and swift up and down, guarantees traffic safety, construction safety and personal safety, operate comfortable, compact conformation, keep in repair easy.
