Description
Technical field
The utility model belongs to extractive equipment power shovel technical field, particularly relates to a kind of electric shovel bucket front wearing bush.
Background technology
Surface mining work under bad environment, more serious as the wearing and tearing in each component working of main extractive equipment power shovel, particularly scraper bowl digs in the process of ore deposit, the scraper bowl of power shovel directly contacts ore wearing and tearing and is exceedingly fast, especially teeth place and teeth antetheca are installed, when the teeth of excavator excavates, teeth antetheca impacts by ore, serious wear, the teeth of general excavator is the interchangeable consumable accessory be arranged on scraper bowl, the replacement cycle of teeth is 20 days-30 days, and the teeth antetheca of this structure is non-exchange, once serious wear, whole power shovel scraper bowl must be changed after exceeding the limit of wear, for enterprise, this will be a very large expense, increase and produce.
Summary of the invention
The purpose of this utility model is to provide a kind of electric shovel bucket front shoe, installs wearing bush, thus avoid scraper bowl antetheca wear and tear by adopting at scraper bowl antetheca place easy to wear, extends scraper bowl antetheca application life, reduces scraper bowl and change, reduction spare parts consumption.
The purpose of this utility model is realized by following technical proposals:
Electric shovel bucket front wearing bush of the present utility model, comprise scraper bowl, the center teeth mount pad being positioned at the scraper bowl antetheca on front side of scraper bowl and being located in the middle part of this scraper bowl antetheca, symmetry is located at side teeth mount pad I and the side teeth mount pad II of these teeth mount pad both sides, center, it is characterized in that being respectively equipped with antetheca gripping sleeve I between described center teeth mount pad and side teeth mount pad I, antetheca gripping sleeve II is respectively equipped with between described side teeth mount pad I and side teeth mount pad II, described antetheca gripping sleeve I is by U-shaped cover, one group of trip bolt that symmetry is located on this U-shaped cover two side formed with the one group of lock washer be enclosed within this group of trip bolt, described U-shaped puts the one group of screwed hole being provided with and being threaded with described one group of trip bolt, described scraper bowl front side wall is provided with one group of screw and inlays nest, the position that nest inlayed by this screw is corresponding with one group of screwed hole that described U-shaped puts.
The form of structure of described antetheca gripping sleeve II is identical with described antetheca gripping sleeve I, and described U-shaped cover is cast steel one-shot forming part.
The openend of the U-shaped cover in described antetheca gripping sleeve I is processed into skewed, and linearity is processed in the openend of the U-shaped cover in described antetheca gripping sleeve II.
The utility model has the advantages that:
1, the utility model adopts the mode of rapid wear place, scraper bowl antetheca local being set up to wearing bush, extends the useful life of scraper bowl antetheca;
2, wearing bush of the present utility model is interchangeable consumable accessory, screws clamp, processing ease, equally with the teeth of excavator upgrades at any time, convenient and swift, save maintenance time.

Fig. 2 is the top view of the utility model Fig. 1
Fig. 3 is the A-A cutaway view Amplified image of the utility model Fig. 1.
Detailed description of the invention
Detailed description of the invention of the present utility model is further illustrated below in conjunction with accompanying drawing.
As Fig. 1, 2, shown in 3, electric shovel bucket front wearing bush of the present utility model, comprise scraper bowl 1, the center teeth mount pad 7 being positioned at the scraper bowl antetheca 3 on front side of scraper bowl and being located in the middle part of this scraper bowl antetheca, symmetry is located at side teeth mount pad I 5 and the side teeth mount pad II 2 of these teeth mount pad 7 both sides, center, the teeth of general excavator is five, spacing between each teeth is roughly the same, be about 100 millimeter, this section of antetheca is often subject to serious wear after intense impact, it is characterized in that being respectively equipped with antetheca gripping sleeve I 4 between described center teeth mount pad 7 and side teeth mount pad I 5, two antetheca gripping sleeves I 4 are symmetrical arranged, antetheca gripping sleeve II 6 is respectively equipped with between described side teeth mount pad I and side teeth mount pad II, two antetheca gripping sleeves II 6 are symmetrical arranged, described antetheca gripping sleeve I overlaps 4-1 by U-shaped, one group of trip bolt 4-3 that symmetry is located on this U-shaped cover two side formed with the one group of lock washer 4-2 be enclosed within this group of trip bolt 4-3, described U-shaped cover 4-1 is provided with the one group of screwed hole be threaded with described one group of trip bolt 4-3, described scraper bowl front side wall is provided with one group of screw and inlays nest 8, the position that nest 8 inlayed by this screw is corresponding with one group of screwed hole that described U-shaped puts.As long as U-shaped cover is enclosed within during installation on the antetheca of two space widths, alignment screw inlays nest, screw and lock screw, once U-shaped overlaps breakage and replaceable, convenient and swift, time saving and energy saving.
The form of structure of described antetheca gripping sleeve II is identical with described antetheca gripping sleeve I, is all made into U-shaped sheath, and described U-shaped cover is cast steel one-shot forming part, and this steel-casting material can select ZG42CrMO, ZG30Mn, ZG230-450 etc., and scuff resistance is good.
The openend of the U-shaped cover in described antetheca gripping sleeve I is processed into skewed, and in order to be match with power shovel antetheca partial structurtes, linearity is processed in the openend of the U-shaped cover in described antetheca gripping sleeve II.
