Abstract
The utility model relates to a tool head of air operated percussion tool for rammed earth, which is also provided with a drill shank, a spring sleeved on the drill shank for connecting elastically the drill shank and an air pressure gun. One end of the drill shank is used for coordinating with the air pressure gun, and the other end is connected fixedly with a tamping plate vertical with the drill shank. As a tamping plate is connected fixedly with one end of original pick drill shank, an air operated percussion tool head for rammed earth is formed, which is a vibrating compaction to the tamping of loose earth when being arranged at the air pressure gun. As the utility model has small volume and simple and flexible operation, in particular, the utility model is suitable for tamping of loose earth in small working procedure, and reduces labor intensity, which solves the problems of loose earth tamping of small working procedure in a better manner.
Description
Technical field:
The utility model relates to the pneumatic percussion tool that the medium and small scope of operation of a kind of civil engineering is used, and relates to the tool heads of pneumatic percussion tool specifically.
Background technology:
Pneumatic percussion tool is a kind of by air pressure gun be installed in the instrument that the tool heads on the air pressure gun is formed, pneumatic percussion tool common in the civil engineering operation is exactly a pneumatic pick, it is made up of air pressure gun and the pick that is installed on the air pressure gun, pick then is enclosed within by a drill steel, and is used for drill steel on the drill steel and forms with the spring that air pressure gun elasticity is connected, drill steel one end is used for cooperating with air pressure gun, the other end is cone-shaped excavation end (see figure 1), and this pneumatic pick can better solve little scope of operation concrete breaking.At present little of the face compacting of loosening the soil to especially building some that often run in the engineering in the civil engineering, the method that but never had solves, now water rams or artificial ramming mostly, and the effect that wastes time and energy also is difficult to reach requirement, particularly repairs road, the operation dead angle area, and pit backfill, more can't implement effective compacting with existing method, because can't be with the compacting of loosening the soil, these places are not spent several years and will be occurred subsiding, sink, ftractureing, and have a strong impact on work quality.Therefore study a kind of little scope of operation that is adapted to, tamp that effective compacting instrument improves rammer soil property amount and efficient is problem demanding prompt solution in the civil engineering work.
The utility model content:
The purpose of this utility model is existing pneumatic pick pick is changed, and a kind of little scope of operation, pneumatic percussion tool head that the compacting quality is good, soil is rammed in high being used to of efficient of being applicable to is provided.
The technical scheme that the utility model is taked is: it still has a drill steel, and is enclosed within and is used for the spring that drill steel is connected with air pressure gun elasticity on the drill steel, and an end of drill steel is used for cooperating with air pressure gun, the other end is affixed tamping plate vertical with drill steel.
In order to smash some hard stone or the soil blocks in the soil, it is more closely knit that earth rammer is got, and is connected with cone under the tamping plate.
Since the utility model will have now an end of pick drill steel affixed a tamping plate, thereby formed a kind of pneumatic percussion tool head that is used to ram soil, when being installed to it on the air pressure gun, it is a kind of vibration compacting to the compacting of loosening the soil, because its volume is little, simple to operate flexible, therefore be adapted to the little compacting of loosening the soil of making face especially.When ramming soil, should note adopting compaction in layers, every layer is loosened the soil unsuitable blocked uply, and the compacting dot spacing is advisable to be slightly smaller than the tamping plate diameter, and the compacting effect might as well.Reduced labour intensity simultaneously.Make the little scope of operation loosen the soil the compacting problem obtained good solution.
Description of drawings:
Fig. 1 is the structural representation of existing pneumatic pick pick.
Fig. 2 is the structural representation of an embodiment of the present utility model.
Fig. 3 is the structural representation of another embodiment of the utility model.
As can be seen from Figure 1, existing pneumatic pick pick has a drill steel 1,, and to be enclosed within the spring 2, drill steel 1 one ends that are used for drill steel on the drill steel 1 and are connected with air pressure gun elasticity be that working end 3 is cone-shaped, and the other end is used for cooperating with air pressure gun.
The utility model is compared with pick shown in Figure 1 as can be seen from Figure 2, and except that the working end 3 of drill steel 1 was a tamping plate 4 vertical with drill steel 1, other position was identical.Therefore the utility model is connected just the same with being connected also of air pressure gun with pick with air pressure gun.Earlier spring 2 is inserted in drill steel 1 during manufacturing, again with the working end 3 of tamping plate 4 affixed (can weld) to drill steel 1.
After installing to the utility model on the air pressure gun during use, can tamp loosening the soil, when ramming soil, should adopt compaction in layers, every layer is loosened the soil unsuitable blocked uply, is advisable with 100-150mm, compacting point distance should be less than tamping plate 4 diameters, such as tamping plate 4 diameters is 120mm, and the compacting dot spacing is 100 * 100, all tamps to guarantee every layer.Loosen the soil by after the compacting layer by layer, can not occur again subsiding naturally, cracking phenomena, solved the present little scope of operation problem that the compacting time is long, efficient is low, labour intensity is big of loosening the soil thus.
Fig. 3 is an another embodiment of the present utility model, as can be seen from the figure, all parts and the structure that it has kept existing pneumatic pick pick only installed (can weld) perpendicular to a tamping plate 4 of drill steel 1 above pointed cone 5, like this in ramming process, in case of hard stone is arranged in the soil, just it can be smashed, reach better compacting effect.
The shape of the utility model tamping plate 4 can be arbitrarily, as circle, rectangle, polygon etc.
