Abstract

The utility model relates to a stone slag tamping tool which is the improvement for the structure of a stone slag tamping tool of a railway ballast bed. The utility model comprises a host machine and a secondary machine. The utility model is mainly characterized in that two V belts are arranged on a main driving wheel and an eccentric wheel of the host machine; a main beam of a walking frame forms a concave shape. The utility model has the advantages of firm transmission belts, increased depth and quality of tamping, easy moving on a railway, etc.

Description

Stone slag tamping tool

The utility model relates to the improvement of small-sized railway ballast ballast tamping tool structure, and it comprises main frame, walker.

The at present domestic existing small-sized railway ballast ballast tamping tool that generally uses is simple in structure, suitable, but also has following major defect:

1, the belt of transmission power is fragile:

The V-belt of existing transmission power is single, is under overload state, to work, therefore fragile (usually just damaging a belt in 2-3 hour), the serious waste that this not only causes belt has also influenced operating efficiency;

2, tamping degree of depth deficiency:

Along with the increase of total volume of railway freight, to the tamping degree of depth and the new requirement of quality proposition of railway roadbed ballast, but because the structural limitations of the girder of present small-sized ballast tamping tool still can not satisfy this requirement;

3, on railway, move difficulty:

When moving main frame usually, at first need to raise main frame, make tamping pickaxe not limited by the walking of girder, could promote main frame then and leave walker.

The purpose of this utility model is exactly at the problems referred to above, provides a kind of transmission power belt not fragile, makes the darker ballast tamping tool of the degree of depth firm by ramming.

The purpose of this utility model is achieved in that exactly in the improvement of doing on the basis of existing structure with the lower part: two V belts are set on the power wheel on the main frame, eccentric wheel; The girder of walker is spill down, realizes above-mentioned purpose of the present utility model with this.

Major advantage of the present utility model:

1, transmission belt is not fragile:

Because the utility model adopts two V belts, just can overcome the work of existing single V belt overburden, just can prolong the application life of transmission belt greatly;

2, improved and made the degree of depth, quality firm by ramming:

Because the girder of walker is arranged to down spill, just can guarantee that duty than the hoist cylinder that extends under the stable case, just can guarantee the degree of depth and the quality of making firm by ramming.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the transmission device part-structure left view of Fig. 1;

Fig. 3 is the vertical view of the vibrating grid of Fig. 1;

Fig. 4 is the left view of the walker of Fig. 1;

Fig. 5 is the local enlarged diagram of Fig. 4.

Below in conjunction with accompanying drawing concrete structure of the present utility model is further described:

The utility model comprises main frame 4, walker 2, main frame 4 mainly is made up of transmission device 7, hoist cylinder 11, clamping cylinder 8, tamping pickaxe 3, walker 2 mainly is made up of girder 4, support bar 13, and transmission device 7 is made up of power wheel 10, eccentric wheel 5, V belt 9.Two V belts 9 are set on power wheel 10, eccentric wheel 5; The girder 1 of walker 2 is to be spill down.

Because the girder 1 of walker 2 is down spill, tamping pickaxe 3 just can descend thereupon, just can be in assurance than the hoist cylinder 11 that extends under the stable state, and that has deepened ballast makes the degree of depth and quality firm by ramming.Certainly the following spill of girder 1 is under the situation that construction operation on the railway 14 allows.

Be two V belts 9 of energy device, the support plate 12 of the vibrating grid 6 of eccentric wheel 5 can make inside spill.

Can guarantee that has deepened ballast makes the degree of depth and quality firm by ramming than lengthening hoist cylinder 11 under the stable state.Certainly the following spill of girder 1 is under the situation that construction operation on the railway 14 allows.

Claims

1, the ballast tamping tool comprises main frame 4, walker 2, it is characterized in that being provided with on power wheel 10, eccentric wheel 5 two V belts 9, and the girder 1 of walker 2 is to be spill down.

2, ballast tamping tool according to claim 1, the support plate 12 that it is characterized in that the vibrating grid 6 of eccentric wheel 5 is to be inside spill.
