Abstract
The utility model provides a rectifiable trenching machine, which comprises a rack and a grab bucket, wherein the grab bucket is connected to the lower end of the rack; more than one bucket tooth is respectively arranged on lower edges of the left side and the right side of the grab bucket; and more than one rectifying tooth is arranged on the lower side of the front side or the rear side of the grab bucket. According to the rectifiable trenching machine disclosed by the utility model, by arranging the rectifying teeth on the lower edge of the front side or the rear side of the trenching machine, a core stratum is broken by the rectifying teeth during trenching construction in places with different hardness, thus an impediment effect of the rock stratum on the grab bucket is overcome, and balance of the grab bucket and normal construction in the construction process can be also ensured.
Description
Technical field
The utility model relates to a kind of groover, particularly a kind of groover of rectifying a deviation.
Background technology
In road and subway construction process, often to use groover and carry out the grooving construction.See also Fig. 1, it is existing a kind of groover structure chart, and it comprises frame 1 and the grab bucket 2 that is connected frame 1 lower end, and the left and right sides of grab bucket 2 is provided with row's bucket tooth 3, is convenient to stretch in the soil layer.
During construction, the left part 4 of grab bucket 2 can rotate around lower sustainer 6 with right part 5, thereby can implement soil diging groove-forming.
But the landform of constructing sometimes is comparatively complicated, for example in No. ten line west of a city of the Line of Nanjing Subway way station construction of diaphragm wall process; Be mainly soft layer in the 10m depth bounds of residing stratum, station, 10m with next be harder weathered rock formation, present soft down hard characteristics; And native rock interface is uneven; The grab bucket 2 of groover only depends on the bucket tooth 3 of self can't guarantee balance when going into the rock stratum by layer soil, and 2 both sides, the front and back rock-soil layer hardness of promptly grabbing bucket is different; Grab bucket 2 can't guarantee normal construction very easily along the scar deflection.
The utility model content
The purpose of the utility model is to propose a kind of groover of rectifying a deviation, to solve the problem that deflection can appear in existing groover grab bucket.
The utility model proposes a kind of groover of rectifying a deviation, and comprises a frame and a grab bucket, and this grab bucket is connected this frame lower end, and the lower edge, the left and right sides of this grab bucket is provided with an above bucket tooth, and this grab bucket front side or rear side lower edge are provided with the tooth of rectifying a deviation more than.
Further, described groover of rectifying a deviation also comprises an above probe that is used to monitor this grab bucket gradient, and this probe is arranged on this frame.
Further, this correction tooth is set to arrow shaped, and the direction of arrow down.
Further, this correction tooth lower end is than low 5 centimetres of this bucket tooth lower end.
Further, grab bucket front side or rear side are provided with an above connecting hole, and this correction tooth is through being bolted in this connecting hole.
With respect to prior art; The beneficial effect of the utility model is: the utility model is through being provided with the correction tooth in the grab bucket front side of groover or the lower edge of rear side; Thereby when carrying out trenching construction in the different place of soft durometer; Can utilize the correction tooth to grab the detritus layer, thereby overcome the inhibition of rock stratum, also can guarantee the balance and the normal construction of grabbing bucket in the work progress grab bucket.
Description of drawings
Fig. 1 is existing a kind of groover structure chart;
A kind of example structure figure of the groover that Fig. 2 can rectify a deviation for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 2, a kind of example structure figure of the groover that it can be rectified a deviation for the utility model, it comprises frame 1 and grab bucket 2, and grab bucket 2 is connected the lower end of frame 1, and frame 1 is provided with a plurality of probes 7, is used for monitoring the gradient of grab bucket 2.The lower edge, the left and right sides of said grab bucket 2 is provided with an above bucket tooth 3, and the front side of grab bucket 2 or the lower edge of the side in the rear side are provided with correction tooth 8 more than, are used for grabbing the detritus layer, to play the correction effect.Described correction tooth 8 is through being bolted in the connecting hole of offering on grab bucket 2 front side or the rear side 9.In the present embodiment, the quantity of connecting hole 9 is convenient to dismantle as required and change correction tooth 8 greater than the quantity of correction tooth 8.
In the present embodiment, described correction tooth 8 is an arrowhead form, and its direction of arrow down.Preferred correction tooth 8 is of a size of the manganese steel of long 50cm (rectangle segment length 35cm, leg-of-mutton arrow segment length 15cm), wide 10cm, thick 3-4cm.And in order to reach rectifying effect preferably, the lower end of correction tooth 8 will be lower than bucket tooth 3 lower ends, and tooth 8 lower ends of for example rectifying a deviation are than the low 5cm in bucket tooth 3 lower ends.
The groover that can rectify a deviation is when grabbing soil, if deflection does not take place in grab bucket 2, can unload correction tooth 8 and construct.And sense grab bucket during 2 run-off the straights when probe 7, when promptly running into the rock stratum, need suspension of works, and the tooth 8 of will rectify a deviation installs in the grab bucket 2, and make the tooth 8 aligning rock stratum of rectifying a deviation.Grab bucket 2 left part 4 rotates around fulcrum 6 with right part 5 and when preparing to grab soil; Because stretching out the part of grab bucket 2, correction tooth 8 is longer than the part that bucket tooth 3 stretches out grab bucket 2; So correction tooth 8 can touch the rock stratum earlier, thereby can grab the detritus layer earlier, like this at grab bucket 2 and bucket tooth 3 when grabbing soil; Just can not receive the rock stratum and hinder, and keep the grab bucket balance.
More than the disclosed several specific embodiments that are merely the utility model; But the utility model is not limited thereto; Any those skilled in the art can think variation, only otherwise exceed the said scope of appended claims, all should drop in the protection domain of the utility model.
