Abstract
The utility model discloses an excavation loader with a bendable scraper conveyor. The excavation loader comprises a working mechanism, a traveling mechanism and the scraper conveyor. The scraper conveyor comprises a scraper chain (5) and grooves, the grooves include a front groove (1), a middle groove (2) and a tail groove (3), a lifting cylinder (6) capable of driving two ends of the corresponding groove to ascend and descend is arranged on the middle groove, a rotating mechanism (4) capable of driving the tail groove to rotate left and right is arranged between the middle groove and the tail groove and comprises connecting hinged supports (8), the connecting hinged supports (8) are respectively fixedly connected with the middle groove and the tail groove, are nested in each other and are movably connected with each other by a connecting pin (9), abrasion-resistant sleeves (10) are arranged among the connecting pin and the connecting hinged supports, and a rotating cylinder (7) capable of driving the tail groove to rotate around the connecting pin left and right is arranged between the middle groove and the tail groove. The excavation loader has the advantages that non-working hours can be saved, the construction efficiency and the construction production safety can be improved, and the labor intensity can be relieved.
Description
Technical field
The utility model relates to caterpillar type loader digger, refers more particularly to the loader-digger that a kind of drag conveyor can bending.
Background technology
Along with the development of world industry, caterpillar type loader digger is widely used in, in the engineerings such as bridge, railway tunnel, hydraulic engineering and mine laneway, having become the indispensable production equipment of underground passage.The transport establishment of caterpillar type loader digger by front groove free bearing with lift groove oil cylinder and be connected with frame.Traditional transport establishment is straight formula, types of transportation is more single: (1), when the less tunnel of turning radius, due to the transport establishment head of caterpillar type loader digger, the standard knot of Xu Jiang transport establishment is dismantled and could be passed through, cause the waste of manpower and materials, stopped over construction speed.(2) the supporting two fortune equipment at caterpillar type loader digger rear are generally granby car, shuttle car, skip bucket, automobile, two fortune belts etc., and the corollary equipment at rear need be over against the center of caterpillar type loader digger transport establishment, normally material feeding.When caterpillar type loader digger turning work or supporting two fortune facilities because tunnel design needs, when track can not be arranged between two parties, can cause supporting two normally material feedings of fortune equipment, cause the adaptation condition scope of caterpillar type loader digger greatly to dwindle.
Utility model content
There is the little problem of above-mentioned adaptation condition scope in the transport establishment for caterpillar type loader digger, the utility model provides that a kind of drag conveyor can bending, can adapt to for a long time loader-digger various adverse circumstances work, that reliability is high.
The technical scheme that the technical problems to be solved in the utility model is taked is: the loader-digger that described drag conveyor can bending comprises operating mechanism, walking mechanism and drag conveyor, described drag conveyor comprises scraper chain and cell body, described cell body comprises front cell body, central slot and afterbody cell body, on central slot, be provided with the elevating ram that can make the lifting of cell body two ends, between central slot and afterbody cell body, be provided with the slew gear that can make afterbody cell body left-right rotation, described slew gear comprises the free bearing that is connected being fixedly linked with afterbody cell body with central slot respectively, described connection free bearing phase embedding is also movably connected with connecting pin, described connecting pin is provided with wear-resistant sleeve with being connected between free bearing, between described central slot and afterbody cell body, be provided with and can make afterbody cell body around the angling cylinder of connecting pin left-right rotation.
Operating principle of the present utility model is: on the cell body of drag conveyor, increase slew gear, by hydraulic system, drive angling cylinder to make the afterbody cell body of drag conveyor can horizontally rotate (left and right respectively rotates 45 °); Drive elevating ram to make cell body make two ends Height Adjustment up and down, can meet preferably the tunnel that turning radius is less, and meet on bend to two and transport material, the operating mode such as rail feeding partially, scraper chain adopts whole chain ring type sleeve scraper chain, large with wearing plate contact area, can change direction along with the rotation of afterbody cell body, avoid the chain problem of turning over of bringing because of cell body revolution.
The utility model is due to the cell body energy oscilaltion in drag conveyor, and afterbody cell body energy left-right rotation, when at the less roadway construction of turning radius, the left-right rotation that can pass through cell body oscilaltion and afterbody is smoothly by the less tunnel of turning radius, can make the supporting two fortune equipment at loader-digger rear need be over against the also normally material feeding of center of caterpillar type loader digger transport establishment, and do not need with manually dismantling cell body, both saved the non-working time, improve efficiency of construction, alleviate again labour intensity, improved construction production security.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model,
Fig. 2 is plan structure schematic diagram of the present utility model,
Fig. 3 is the Y-Y broken section structure for amplifying schematic diagram of Fig. 1.
In the drawings, 1, front cell body 2, central slot 3, afterbody cell body 4, slew gear 5, scraper chain 6, elevating ram 7, angling cylinder 8, connect free bearing 9, connecting pin 10, wear-resistant sleeve 11, axle bed.
The specific embodiment
At Fig. 1, in Fig. 2 and Fig. 3, described drag conveyor can bending loader-digger comprise operating mechanism, walking mechanism and drag conveyor, described drag conveyor comprises scraper chain 5 and cell body, described cell body comprises front cell body 1, central slot 2 and afterbody cell body 3, on central slot, be provided with the elevating ram 6 that can make the lifting of cell body two ends, between central slot and afterbody cell body, be provided with the slew gear 4 that can make afterbody cell body left-right rotation, described slew gear comprise be fixedly linked with afterbody cell body with central slot respectively be connected free bearing 8, the embedding of described connection free bearing activity phase is also movably connected with connecting pin 9, described connecting pin is provided with wear-resistant sleeve 10 with being connected between free bearing, between described central slot and afterbody cell body, be provided with angling cylinder 7, angling cylinder one end is fixed on middle cell body, piston external part is connected with the axle bed 11 being fixed on afterbody cell body, in angling cylinder when work, can make afterbody cell body around connecting pin 45 ° of left-right rotation in level.In addition, scraper chain adopts whole chain ring type sleeve scraper chain, large with wearing plate contact area, can change direction along with the rotation of afterbody cell body, has avoided the chain problem of turning over of bringing because of cell body revolution.
When at the less roadway construction of turning radius, thereby make cell body oscilaltion and angling cylinder make afterbody cell body left-right rotation smoothly by the less tunnel of turning radius by controlling elevating ram, supporting two fortune facilities are because tunnel design needs in addition, when track can not be arranged between two parties, at needs when filling with substance, by controlling slew gear, by afterbody cell body, turn to the enterprising luggage material of two fortune equipment, make the supporting two fortune equipment at loader-digger rear need be over against the also normally material feeding of center of caterpillar type loader digger transport establishment.
