Description

Integrated hydraulic oil tank rear supporting structure for short-body tunneling and anchoring machine Technical Field The invention belongs to the technical field of heading machine engineering machinery, relates to an integrated hydraulic oil tank of a short-body anchor-digging machine, and particularly relates to a rear supporting structure of the integrated hydraulic oil tank for the short-body anchor-digging machine. Background The short-machine body anchor driving machine is mainly used for driving and anchor protection operation under the low working condition of a coal mine tunnel, and the height of the whole machine is strictly limited. Thus, the internal space layout of the equipment is extremely compact, and layout optimization of the functional components is a great challenge in the design of a low-fuselage anchor extractor. The existing short-body anchor excavator generally adopts a split type design, a hydraulic oil tank and a rear supporting frame are independent components, the rear supporting frame is a main beam frame connected with the rear of an anchor excavator body frame and used for supporting a first conveyor, an electric control box and an oil pump motor, and the hydraulic oil tank is an independent box and is generally arranged in other spaces at the rear or upper part of the anchor excavator. The traditional layout has some problems that firstly, an independent hydraulic oil tank needs to occupy very narrow precious space, the flexibility of the whole machine layout is greatly limited, in order to accommodate the oil tank, the height or width of the whole machine sometimes has to be increased, secondly, the pipeline connection between the independent oil tank and the oil tank motor duplex pump and the actuating mechanism is long and complex, the pressure loss, the energy consumption and the oil leakage risk are increased, furthermore, the rear support frame only bears the supporting function, the huge beam body space of the rear support frame is not effectively utilized, the waste of the structure and the space is caused, and finally, the split type design also causes the problems of large number of parts, high manufacturing cost, large whole machine weight and the like. Disclosure of Invention The invention aims to provide an integrated hydraulic oil tank rear supporting structure for a short-body anchor driving machine, which can fully utilize the inner space of the rear support of the anchor driving machine on the premise of not sacrificing the structural strength and hydraulic performance of the anchor driving machine, optimize the space layout of the short-body anchor driving machine to the maximum extent and realize the efficient fusion of the hydraulic oil tank and the supporting structure. The technical scheme adopted by the invention for achieving the purpose is as follows: the utility model provides a support structure behind integrated hydraulic tank for anchor machine is dug to short fuselage, includes back support frame girder and oil tank chamber group, oil tank chamber group and back support frame girder are integrated as an organic wholely, and oil tank chamber group is the concave shape structure, and the longitudinal back support muscle board in back support girder both sides encloses as the lower passageway chamber of oil tank chamber group. The rear support frame main beam comprises a bearing platform panel and a longitudinal rear support rib plate, a lower passageway cavity surrounded by the longitudinal rear support rib plate is buckled below the bearing platform panel, an oil return port, a cleaning port and an oil suction port are arranged on the bearing platform panel and are respectively communicated with the lower passageway cavity, oil discharge ports are arranged at the bottoms of two sides of the lower passageway cavity, and a lower passageway cavity magnet rod is arranged in the middle of the lower bottom of the cleaning port of the lower passageway cavity. Further, the lower aisle cavity magnet rod is supported and fixed through the magnet rod supporting bracket. Further, the oil tank cavity group sets up the cushion cap panel top at back support frame girder, and the oil tank cavity group includes oil return chamber, oil absorption chamber and goes up passageway chamber, and oil return chamber and oil absorption chamber are through last passageway chamber intercommunication, and simultaneously, oil return chamber is through the oil return mouth and the passageway chamber intercommunication down that set up on the cushion cap panel, and oil absorption chamber sets up oil suction port and passageway chamber intercommunication down on passing through the cushion cap panel, and oil return chamber, go up passageway chamber, passageway chamber down, oil absorption chamber form a recess shape oil tank, and the depressed part is used for dodging the first conveyer chute of anchor machine.
