Abstract
The utility model relates to underground construction machinery, in particular to an excavating device. A suspension impact excavating device comprises an outer guide frame, a grab, a deviation correction device and a drive cylinder, and the excavating device further comprises an inner guide frame which can be vertically movably arranged in the outer guide frame and be connected with the grab through a sliding frame; and an impact drive device which is arranged in the outer guide frame and connected with the inner guide frame by driving. The excavating device can provide the additional impact power for the grab, lead the grab to burst the earth surface with greater hardness and smoothly complete the excavation work of harder strata.
Description
Technical field
The utility model relates to underground construction machinery, specifically, relates to a kind of excavating gear.
Background technology
In the underground construction field, it is the suspension type grab bucket that excavation ground is moved the earthwork modal.These grab buckets are crept into the face of land and are excavated the earthwork by deadweight and static pressure.Yet, subsurface picture is very complicated, run into the bigger subterranean layer of some hardness ratios, as hard sand bed, the static pressure that excavator provides is not enough so that the grab bucket chi pierces, therefore, a kind of Impact Bucket Grab machine has abroad appearred, it is when running into above-mentioned situation, and the grab bucket suspension is loosened grab bucket, make the excavating gear (comprise grab bucket and saddle) of grab claw thus being freely falling body goes to impact the purpose that the face of land reaches excavation.Yet, find that through test though this kind equipment can achieve the goal, grab bucket in the process of landing, the oil pipe of hoist engine, wire rope, connection can be subjected to shock effect and destroy, freely falling body can wash away hole wall simultaneously, causes landslide, influences the operation of entire equipment.And because cage body is done the movement of falling object synchronously, its verticality is difficult to guarantee.The employing that also has increases the excavating gear tonnage, and improve deadweight and achieve the goal, but along with equipment tonnage increases, whole excavator weight heightens, and seems very heavy, from producing, transport and even using maintenance all very inconvenient, waste material consumes a large amount of energy simultaneously.
The utility model content
The utility model is intended to solve the described defective of prior art, and a kind of impact type excavating device is provided.The utility model can provide extra impact power for grab bucket, makes it be washed open the bigger face of land of hardness, finishes the excacation on harder stratum smoothly.
The utility model is achieved in that
A kind of suspension impact type excavating device, it comprises outer saddle, grab bucket, deviation correcting device and driving oil cylinder, it also comprises;
Interior saddle, it is arranged in the outer saddle and by travelling carriage to fast moving up and down and connects described grab bucket;
Impulse drive means, it is installed in the outer saddle and with interior saddle driving and is connected.
Described a kind of suspension impact type excavating device, described grab bucket is a hammer grab, within the big bucket, at least two group impact teeth is housed about it, these impact teeth all are fixed on the grab bucket bearing.
Described a kind of suspension impact type excavating device, the hanging steel rope that described impulse drive means maybe can be loosened for impact oil cylinder group, blow cylinder group.
The utility model increases impulse drive means for grab bucket, when grab bucket also has certain distance on the distance excavation face of land, the saddle transfixion, impulse drive means work, promote grab bucket fast, for grab bucket provides huge additional impact power, simultaneously, the grab bucket body is set up impact teeth becomes Impact Bucket Grab, thereby successfully realizes the excacation than hardcore.Because the impact force that impulse drive means provides is very big, but several times and even number decuple the tonnage of excavating gear own, and therefore, the utility model can utilize the stratum that the excavating gear of less tonnage excavates needs large-scale excavating gear.
Description of drawings
Below, in conjunction with the accompanying drawings, further specify the utility model:
Fig. 1 is the utility model schematic diagram.
Fig. 2 is described Impact Bucket Grab schematic diagram.
The specific embodiment
As shown in Figure 1, a kind of suspension impact type excavating device, its top is provided with hitch point 8, and it comprises outer saddle 1, grab bucket 2, deviation correcting device 3 and driving oil cylinder 4, and it also comprises;
Interior saddle 5, it is arranged on to fast moving in the outer saddle 1 and by travelling carriage 6 up and down and connects described grab bucket 2;
Impulse drive means 7, it is installed in the outer saddle 1 and with interior saddle 5 drivings and is connected.
As shown in Figure 2, described grab bucket 2 is a hammer grab, within the big bucket 21,22, at least two group impact teeth 23 is housed about it, and these impact teeth 23 all are fixed on the grab bucket bearing 24.
Described impulse drive means 7 comprises that one of impact oil cylinder group, blow cylinder group or both use jointly.
Claims (3)
1. one kind is hung impact type excavating device, and it comprises outer saddle, grab bucket, deviation correcting device and driving oil cylinder, it is characterized in that, it also comprises;
Interior saddle, it is arranged in the outer saddle and by travelling carriage to fast moving up and down and connects described grab bucket;
Impulse drive means, it is installed in the outer saddle and with interior saddle driving and is connected.
2. according to the described a kind of suspension impact type excavating device of claim 1, it is characterized in that described grab bucket is a hammer grab, within the big bucket, at least two group impact teeth are housed about it, these impact teeth all are fixed on the grab bucket bearing.
3. according to the described a kind of suspension impact type excavating device of claim 1, it is characterized in that described impulse drive means is the hanging steel rope that impact oil cylinder group, blow cylinder group maybe can be loosened.
