Abstract
An excavator bucket for small-section tunnel earthwork comprises a bucket body, wherein clamping grooves are formed in two sides of the bucket body, and the inserting opening direction of each clamping groove is perpendicular to the opening surface of the bucket body; the excavator bucket comprises an excavator bucket body and is characterized in that a reinforcing steel plate with a sharp part at the front end is movably connected in a clamping groove on at least one side of the excavator bucket body, the reinforcing steel plate is movably connected in the clamping groove from the rear side of the excavator bucket body, and the sharp part is located outside the excavator bucket body. The utility model discloses simple structure through carrying out local institutional transformation to current bucket, can insert the reinforcing steel plate when needs excavate small cross section tunnel according to actual need when using, not the time spent removes the reinforcing steel plate. The excavating bucket is suitable for excavating earthwork of a small-section tunnel without influencing the normal function of the original excavating bucket, and is low in manufacturing cost, flexible to use and capable of improving excavating efficiency by more than 4 times compared with manual excavating.
Description
Technical field
The utility model relates to a kind of subterranean tunnel excavating tools, especially a kind of excavator-type shovel clamshell excavator that is applicable to the narrow-bore tunnel earthwork.
Background technology
National each metropolis starts the climax of subway construction at present, in order to reduce the impact of construction of subway on existing traffic as far as possible, many stations adopt hidden construction process construction, and tunneling subway station all relates to the work progress that is gradient to large section from light section mostly, the size of narrow-bore tunnel is generally the wide 3m of high 4m*, soil excavation generally adopts mini-excavator cooperation manually to carry out, but because tunnel cross-section is little, the bucket that existing excavator carries often cannot touch for top and the side in tunnel, need to coordinate a large amount of manpowers go to excavate these buckets dig less than place, effect is low, in workman's digging process, there is the earthwork injured the having a big risk of caving in.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, easy to use, for the high and safe and reliable excavator-type shovel clamshell excavator for the narrow-bore tunnel earthwork of narrow-bore tunnel digging efficiency.
The utility model solves the technical scheme that prior art problem adopts: a kind of excavator-type shovel clamshell excavator for the narrow-bore tunnel earthwork, comprise bucket body, the both sides of described bucket body are equipped with draw-in groove, and the socket direction of described draw-in groove and the opening surface of described bucket body are perpendicular; The reinforcement steel plate that is connected with front end and is provided with sharp-pointed portion in the draw-in groove of at least one side of described bucket body, described reinforcement steel plate is movably connected in draw-in groove by the rear side of bucket body, and makes described sharp-pointed portion be positioned at the outside of described bucket body.
Described reinforcement steel plate outward.
Described reinforcement steel plate is outwards 30 degree bendings.
Described reinforcement steel plate is pegged graft and is fixed in draw-in groove.
Described draw-in groove is welded in the both sides of described bucket body.
The beneficial effects of the utility model are: the utility model is simple in structure, by existing bucket is carried out to local structure of modification, can in the time that needs excavate narrow-bore tunnel, plug according to actual needs in use reinforcement steel plate, and the used time is not removed reinforcement steel plate.In the normal function that does not affect original bucket, be also applicable to the excavation of the narrow-bore tunnel earthwork, and low cost of manufacture, using flexibly, excavation efficiency improves more than 4 times than hand excavation.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is lateral view of the present utility model.
Fig. 3 is the structural representation that the utility model is strengthened steel plate.
In figure: 1-bucket body, 2-draw-in groove, 3-strengthen steel plate, the sharp-pointed portion of 4-.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described:
The front view of a kind of excavator-type shovel clamshell excavator for the narrow-bore tunnel earthwork of Fig. 1 the utility model.For an excavator-type shovel clamshell excavator for the narrow-bore tunnel earthwork, comprise bucket body 1, the both sides of bucket body 1 are all welded with draw-in groove 2.This draw-in groove 2 can be by forming with Plate Welding.
Fig. 2 be a kind of excavator-type shovel clamshell excavator for the narrow-bore tunnel earthwork of the utility model lateral view.As shown in Figure 2, the socket direction of draw-in groove 2 and the opening surface of bucket body 1 are perpendicular; In the draw-in groove 2 of at least one side of bucket body 1, be plugged with reinforcement steel plate 3(that front end is provided with sharp-pointed portion 4 as shown in Figure 3), strengthen steel plate 3 and peg graft and be fixed in draw-in groove 2 by the rear side of bucket body 1, and the sharp-pointed portion 4 that makes to strengthen steel plate 3 is positioned at the outside of bucket body 1.The side and the top soil excavation that reach for normal bucket, steel plate length and bending angle can need to be adjusted according to excavation.According to common experience, preferably strengthen steel plate 3 and be outwards 30 degree bendings.
Concrete use procedure of the present utility model is as follows: (a), in the time of the earthwork of tunneling right side, select the reinforcement steel plate 3 that is outwards 30 degree bendings to be plugged in bucket body 1 right side draw-in groove 2, along with the action of bucket body 1 realizes, right flank and the earthwork of top, right side are excavated; (b), in the time of tunneling left side cubic metre of earth, select the reinforcement steel plate 3 that is outwards 30 degree bendings to be plugged in the draw-in groove 2 of bucket body left side, realize left surface and the left side top earthwork excavated; (c), when the earthwork of tunneling arch, can realize the arch earthwork is excavated in the draw-in groove 2 of bucket body both sides strengthening steel plate 3 and being plugged in.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
