Description of drawings
Fig. 1 is of the present utility model bowing to structural representation;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is the B-B sectional view of Fig. 2;
Fig. 4 praises the structural representation of state for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing 1, Fig. 2 the utility model is further described:
The loader mechanism that is used on the underground carry scraper described in the utility model comprises a dump cylinder 1, two elevating rams 2, big arm 3, a Rocker arm 4, a connecting rod 5 and a scraper bowl 6.Be assurance structure stability of transmission and reliability, and the convenience of assembling and use flexibility, big arm, rocking arm and connecting rod all are ' U ' type frame construction.
Wherein, big arm 3 side views of frame construction are an arcuate structure of upwards digging, and extend respectively laterally at two ends.Big arm 3 the inners of ' U ' type framework are hinged on the frame of underground carry scraper, scraper bowl 6 bottoms and rear end are provided with recess, the outer end of big arm 3 is connected the recess place of scraper bowl 6 bottoms by the bearing pin correspondence, the coupling part is ensconced in the recess like this, shovel fortune process can not cause damage to the junction of big arm 3 with scraper bowl 6, guarantees that scraper bowl 6 reliably uses.Big arm 3 mainly plays the effect that promotes and lift scraper bowl 6, is the main part of the force of underground carry scraper in shovel fortune process, so its shape is thicker.
Two elevating rams 2 are positioned at the frame construction inboard of big arm 3, and are subjected to the protection of big arm framework, prevent that other weight is to the collsion damage of elevating ram 2 in the handling process.The fixed end of two elevating rams 2 is hinged on respectively on the frame of underground carry scraper, and movable end is supported on the big arm framework by the bearing pin correspondence.Taken up space by realizing lifting to greatest extent and reducing elevating ram 2, the movable end of elevating ram 2 is close to the inner of big arm 3, and the orientation of elevating ram 2 is consistent with big arm 3, lifts height to realize the maximum under the minimum stroke.
Dump cylinder 1 is corresponding to the top of big arm 3, and the fixed end of dump cylinder 1 is hinged on the frame of underground carry scraper, and it generally is in level.Connecting rod 5 is connected the movable end of dump cylinder 1 and scraper bowl 6 rear ends near between the position of top by bearing pin, and dump cylinder 1 guarantees scraper bowl 6 operating angles by 6 upsets of connecting rod 5 control scraper bowls, finishes shovel fortune, overturning action under scraper bowl 6 normal conditions.
For further improving scraper bowl 6 overturn angle, control scraper bowl 6 overturning processes, increase the connective stability of connecting rod 5, the also corresponding Rocker arm 4 that is connected with between connecting rod 5 and big arm 3; Rocker arm 4 is connected being connected between the bearing pin of big arm 3 and dump cylinder 1 and connecting rod 5; 3 on Rocker arm 4 and big arm be by the corresponding connection of bearing pin, the close outer end of arm 3 greatly of tie point, Rocker arm 4 plays support and transmission guide effect to big arm 3 and connecting rod 5.
For improving the durability of loader mechanism, in above-mentioned each bearing pin bindiny mechanism, also be respectively equipped with axle sleeve, oil sealing and axle head cover plate, bearing pin connects to improve, the reliability of transmission.
As shown in Figure 3, axle sleeve 12 is enclosed within on the bearing pin 13, and counterrotating connecting rod 5 is enclosed within on the bearing pin 13 by axle sleeve 12, has avoided the direct abrasion of connecting rod 5 rotation processes to bearing pin 13, oil sealing 11 is positioned at axle sleeve 12 two ends, overflows to prevent the lubricant grease that adds in the axle sleeve 12.For preventing that bearing pin 13 from skidding off, also be fixedly connected with axle head cover plate 14 in the outside at bearing pin 13 two ends, axle head cover plate 14 guarantees the reliability of bearing pin 13 connections and the safety of use with bearing pin 13 position relative fixed.
Praise when unloading the ore deposit, as shown in Figure 4, underground carry scraper is by operating grip control dump cylinder 1 and elevating ram 2 associated working.When working in the early stage, scraper bowl 6 keeps the insertion state, and dump cylinder 1 limits scraper bowl 6 angles by connecting rod 5 and Rocker arm 4, promotes mineral with maximum surface area and enters in the scraper bowl 6; Then, control dump cylinder 1 and shrink, drive scraper bowl 6 by connecting rod 5 and Rocker arm 4 and dig, and make the horizontal travel position of scraper bowl 6 maintenances, finish mineral and scoop up with level and migrate.When praising, control elevating ram 2 stretches out, elevating ram 2 drives big arm 3 and upwards digs, because dump cylinder 1 is hinged with frame 7, simultaneously, 6 of dump cylinder 1 and connecting rod 5, Rocker arm 4 and scraper bowls are connected for bearing pin, so praise in the process, dump cylinder 1, connecting rod 5, Rocker arm 4 and scraper bowl 6 can continue to keep scraper bowl 6 levels when rising, avoided mineral to spill from scraper bowl 6, have guaranteed praising smoothly of mineral.And when toppling at last, only need a control dump cylinder 1 to stretch out, by drivening rod 5 and Rocker arm 4 reversible bucket 6, can finish mineral and topple over.By the underground carry scraper after this architecture advances, maximum dump clearance can reach about 1900mm, and the off-load angle reaches 42 degree.And when the needs drop shaft unloaded the ore deposit, said process only needed under the situation of not praising step, directly stretched out by operation dump cylinder 1, just can finish toppling over of scraper bowl 6 smoothly, and is simple, convenient.
