Abstract
The utility model relates to a bucket of an excavator. The bucket of a tunnel excavator comprises a bucket mouth, a bucket enclosure and a bucket bottom, wherein the bucket mouth is provided with two bottom sides which are opposite to each other, and two lateral sides which are opposite to each other, and a bucket tooth is arranged on one bottom side. The bucket of the tunnel excavator is characterized in that: a protrusion device is detachably arranged on the bucket enclosure, and a protrusion end on the protrusion device, which is toward the bucket mouth, is provided with a bottom side of the bucket tooth. According to the bucket of the tunnel excavator, provided by the utility model, the characteristics of the long arm, large flexibility and high efficiency of the excavator can be fully applied; when a machine arm of the excavator is completely extended, the bucket back of the excavator is upward, a blade inclines upwards, surrounding rock soil on an arch crown and a higher place is subjected to vibrating and cutting construction by the blade in the manners of rotation, upward jacking and the like of the machine arm of the excavator, and the surrounding rock soil of a tunnel is mashed, so that the moving times of the excavator and the explosion times are reduced greatly, the tunnel mechanized job execution level and the working efficiency of the tunnel excavator are improved, and the construction progress is accelerated to reduce the safety and quality risks more favorably.
Description
[technical field]
The utility model relates to the machine bucket of excavator.
[background technology]
The tunnel is to build underground or under water and place an iron railway and supply the current building of locomotive motor vehicle.Can be divided into mountain tunnel, submerged tunnel and city tunnel three major types according to its position.For reducing the distance and avoiding the mountain tunnel that is called that steep gradient passes through under the mountain ridge or the hills; For river crossing or straits from the river down or the seabed pass through be called submerged tunnel; For adapt to railway through metropolitan needs in the city underground pass through be called city tunnel.Building maximum in these three types of tunnels is mountain tunnel.In the tunnel excavation process, must understand the classification of country rock.Country rock be behind the tunnel excavation to the influential peripheral rock mass of tunnel stability, rocvk classification is to show the comprehensive strength of rock on every side successively.Different country rock ranks will adopt different excavation technology.When the V level country rock excavation that constitutes with soil property, silty sand; General adopt the side heading method construction, working procedure is construction lofting, explosion, slag tap, subsequent treatment, immediately following supporting etc., after explosion; Country rock soil in the tunnel is loose in a large number; And the usage mining machine further breaks ground, excavates, adorns soil etc., but since the design feature of existing excavator machine bucket can't the native stone of tunnel vault and higher range be broken ground, excavate; Thereby increased the mobile number of times and the explosion number of times of excavator, thereby increased expense such as manual work, machinery, explosive and prolonged the construction period and increased construction risk.
[summary of the invention]
The utility model aims to provide a kind of tunnel excavator machine bucket that can excavate vault and higher part in the tunnel effectively.
The described tunnel excavator machine of the utility model bucket; Comprise quarrel; The bucket group and the bucket end,, quarrel has two relative respectively bases and relative respectively dual-side, and a base wherein is provided with bucket tooth; But described bucket has been installed projection arrangement with helping demolition, and the projecting end on this projection arrangement is provided with the base of bucket tooth towards quarrel.
Preferably, the projecting end on the projection arrangement is arranged between the elongated surfaces of the elongated surfaces of bucket tooth and the group that struggles against.
More preferably, the projecting end on the projection arrangement is parallel with the side of quarrel.
Further preferably, described projection arrangement is a blade.
Further preferably, but both sides buckets has been installed a blade with helping demolition respectively.Perhaps also can but one blade be installed with helping demolition at a side bucket.
Most preferably, described bucket is helped and has been welded a block plate, and steel plate is provided with the insert pocket that is complementary with blade.
The described blade removal of the utility model is flexible, handles very skillfully.Use the excavator of the described excavator machine of the utility model bucket, can fully use excavator brachium, flexibility is big, efficient is high characteristics, when the horn of excavator is in full extension; The bucket of digging machine is gone up dorsad, and blade is in state obliquely, through the rotation of digging machine arm, to modes such as tops, top; Utilize blade that vault and higher position country rock soil are vibrated, cut the soil construction, tunnel surrounding soil is smashed to pieces, thereby reduce the mobile number of times and the explosion number of times of excavator greatly; Thereby expenses such as manual work, machinery, explosive have been reduced; Improve tunnel machine equalization construction level and operating efficiency, accelerating construction progress is so that reduce safety and quality risk better.
[description of drawings]
Fig. 1 is the use sketch map of the utility model;
Fig. 2 is the structural representation of the utility model preferred embodiment;
Fig. 3 is the side diagrammatic sketch of Fig. 2;
Among the figure, the 1-quarrel, the 2-group that struggles against, 3-struggles against at the end, 4-bucket tooth, 5-blade.
[specific embodiment]
As shown in the figure, the tunnel excavator machine bucket of the utility model comprises quarrel 1; Bucket group 2 has two relative respectively bases and relative respectively dual-side with the bucket end 3, quarrel 1, and a base wherein is provided with bucket tooth 4; Welded a block plate respectively in the both sides bucket group 2; Steel plate is provided with insert pocket, is inserted with the blade 5 that matches in this insert pocket, and blade 5 is parallel with the side of quarrel 1.
Use the excavator of the described excavator machine of the utility model bucket, can fully use excavator brachium, flexibility is big, efficient is high characteristics, when the horn of excavator is in full extension; The bucket of digging machine is gone up dorsad, and blade 5 is in state obliquely, through the rotation of digging machine arm, to modes such as tops, top; Utilize blade that vault and higher position country rock soil are vibrated, cut the soil construction, tunnel surrounding soil is smashed to pieces, thereby reduce the mobile number of times and the explosion number of times of excavator greatly; Thereby expenses such as manual work, machinery, explosive have been reduced; Improve tunnel machine equalization construction level and operating efficiency, accelerating construction progress is so that reduce safety and quality risk better.
