Description
Technical field
The utility model relates to a kind of electric excavator, particularly a kind of electric excavator that conveniently changes tooth.
Background technology
Present electric excavator, it comprises revolving dial, A shape frame, last boom, following boom, scraper bowl, shovel bar and auxiliary elevator; The bucket tooth of scraper bowl is a vulnerable part, and average per fortnight just must be changed once, and in the more abominable mining process of ore body condition, it is higher that it changes frequency, can reach jede Woche once; The auxiliary elevator of present electric excavator is used for more change steel rope, and can not be used for changing the bucket tooth of scraper bowl, all leaning on manpower that more than bucket tooths that worn and torn are removed when changing bucket tooth now removes, again new bucket tooth is laid up, and the most small-sized scraper bowl has 6 bucket tooths, the weight of a bucket tooth has more than 100 kilogram, and the weight of the single bucket tooth of Large Electric power shovel even can reach 500 kilograms is changed bucket tooth and the staff is one is required great effort and time-consuming job; Syndeton by improving bucket tooth and toothholder is also arranged at present with the convenient bucket tooth of changing fast, but this must lean on mainly manpower that bucket tooth is brought up to move down, people's labour intensity does not obtain very big alleviating, and the replacing bucket tooth is chronic; Adopt special vehicle to carry and lay bucket tooth at present in addition, though people's labour intensity obtains very big alleviating, and the efficient of replacing bucket tooth is also higher, and it is too high to change the bucket tooth cost like this.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of electric excavator that conveniently changes tooth is provided, and it is time saving and energy saving when changing the bucket tooth of scraper bowl, cost is low.
The technical solution of the utility model is: a kind of electric excavator that conveniently changes tooth, and it comprises revolving dial, A shape frame, last boom, following boom, scraper bowl, shovel bar and changes the tooth device; The lower end of following boom is connected on the electric excavator revolving dial, the upper end of following boom is connected with the lower end of last boom, the shovel bar is installed in rotation on down the upper end of boom, scraper bowl includes bucket tooth, bucket tooth is installed in the scraper bowl mouth lower edge of scraper bowl, and the top of scraper bowl is fixedly connected on the lower end of shovel bar; Change the tooth device and comprise auxiliary elevator, intermediate pulley group and upper arm fixed pulley, auxiliary elevator is installed on the A shape frame, the intermediate pulley group is installed in down on the boom, the upper arm fixed pulley is installed on the boom, auxiliary elevator includes wire rope, wire rope one end is connected on the auxiliary elevator, and its other end is walked around intermediate pulley group and upper arm fixed pulley and bucket tooth and joined.
The further technical scheme of the utility model is: described upper end of going up boom is equipped with head sheave, and the upper arm fixed pulley is installed in the position of boom near head sheave.
The utility model further technical scheme is: described bucket tooth is provided with annulus, and the other end of wire rope is connected on the annulus of bucket tooth.
The utility model compared with prior art has following characteristics:
1, since when changing tooth bucket tooth sling by auxiliary elevator, the staff who changes bucket tooth no longer needs bucket tooth is applied very big vertical force, only need apply very little lateral force to bucket tooth just can change bucket tooth like a cork, the labour intensity of changing the staff of bucket tooth obtains very big alleviating, and changes the also corresponding minimizing of time of tooth;
2, the utility model only increases by one and simply changes the tooth device on existing electric excavator, and its cost of changing scraper bowl is low.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that Fig. 1 is along the enlarged drawing in the A line scope;
Fig. 3 is that Fig. 1 is along the enlarged drawing in the B line scope.
The specific embodiment
Embodiment
As shown in Figure 1: a kind of electric excavator that conveniently changes tooth, it comprises revolving dial 1, A shape frame 2, last boom 3, following boom 4, scraper bowl 5, shovel bar 6 and changes the tooth device; The lower end of following boom 4 is connected on the electric excavator revolving dial 1, the upper end of following boom 4 is connected with the lower end of last boom 3, the upper end of last boom 3 links to each other by the upper end of guy wire with A shape frame 2, shovel bar 6 is installed in rotation on down the upper end of boom 3, scraper bowl 5 includes bucket tooth 51, bucket tooth 51 is installed in the scraper bowl mouth lower edge of scraper bowl 5, the top of scraper bowl 5 is fixedly connected on the lower end of shovel bar 6, scraper bowl 5 upper ends are connected with wire rope, this wire rope is connected with reel on being installed in revolving dial 1 by the head sheave 31 that is installed on the boom 3, this rotating cylinder links to each other with turning motor by gearbox, reel changes toward a direction, scraper bowl 5 rises, and reel is toward changeing in the other direction, and scraper bowl 5 descends; Change the tooth device and comprise auxiliary elevator 71, intermediate pulley group 72 and upper arm fixed pulley 73, auxiliary elevator 71 is installed on the A shape frame 2, intermediate pulley group 72 is installed in down on the boom 4, upper arm fixed pulley 73 is installed in the position of boom 3 near head sheave 31, auxiliary elevator 71 includes wire rope 711, wire rope 711 1 ends are connected on the auxiliary elevator 71, the annulus 52 that its other end is walked around on intermediate pulley group 72 and upper arm fixed pulley 73 and the bucket tooth 51 joins, when changing bucket tooth 51, utilize the strength of auxiliary elevator 71 that bucket tooth 51 is hung suitable height, the staff just can change bucket tooth 51 very easily as long as bucket tooth 51 is imposed less lateral force, after replacing bucket tooth 51 finishes, with auxiliary elevator 71 wire rope 711 is regained again.
