According to the double-rotary-motor oil discharging device, an oil discharging port of the rotary motor is led to the position below the rotary table (C); during oil discharging, an operator can complete the oil discharging work by directly screwing off the plug (8); and by adopting the double-rotary-motor oil discharging device, the motor oil discharging difficulty is reduced, the oil discharging time is shortened, and discharged lubricating oil can be effectively prevented from polluting a machine body.
Description
Technical field
The utility model relates to a kind of jettison gear, relates to the jettison gear that the two rotary motors of a kind of excavator are used particularly.
Background technique
Lubricant oil is the excavator thick material of the indispensable liquid state in position that cogs; these materials are made up of petroleum distillate and the low-molecular-weight multiple additives of HMW; gear played reduce friction; cool; antiseptic and rustproof; sealing; insulation; functions such as cleaning, the function of lubricant oil is more many, and then the material of Tian Jiaing is also more many; correspondingly; the performance of oil product is also more unstable, and this is that the lubricant oil after going bad does not only have the effect of protecting gear because the low-molecular-weight additive of part can be in temperature volatilize away in the higher or strenuous exercise or react and go bad; corrosion gear very easily also; cause gear to damage in advance even scrap, in addition, gear in use for some time; along with after the metal fillings of airborne dust and wear and tear in machines enters lubricant oil; the various performances of machine also can descend thereupon, so lubricant oil just needs to change once in use for some time.
At present, to the digger revolving motor more in the oil change, common practice is to open the drain oil of rotary motor bottom, directly lubricant oil is discharged to by a drain line and connects in the oil drum, and do not have a special-purpose jettison gear, the workman who has does not even directly drain the oil with drain line, this original operation of draining the oil has implemented a lot of drawbacks, and difficulty is big, at first, rotary motor is positioned at the chassis of dredging machine intermediate portion, and overhead (according to the type difference of excavator, this is apart from some variation of meeting less than 1 meter distance for drain oil, but change little), so the narrow space operator need bend to arrive the operation of draining the oil of motor position, and this process has increased operator's intensity and difficulty, has prolonged the operating time; Secondly, it is bigger that the lubricant oil at drain oil place is subjected to bigger pressure effect flow velocity, and directly discharging splashes on the turntable easily, has polluted body and environment on every side.If drain oil can be guided to a maneuverable place, and fix, then can improve the existing operating process of draining the oil.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of excavator two rotary motor jettison gears, and this device can reduce the operation easier of draining the oil, and saves the operating time, and can prevent that lubricant oil from splashing on the body.
To achieve these goals, technical solution adopted in the utility model is: the two rotary motor jettison gears of excavator, comprise drain line, plug, comprise pipe joint in addition, described pipe joint one end is installed on the drain oil of rotary motor, the other end links to each other with a person in charge of tee union, and another person in charge of tee union is connected on the drain line of interflow, the interflow drain line the other end was connected on the wall joint, wherein cross the wall joint and pass connecting plate and link to each other with nut, described connecting plate is fixed on the turntable, and described nut uses the plug shutoff.
Wherein, the arm of described tee union links to each other with the tributary drain line, and the other end of tributary drain line is connected on the drain oil of another rotary motor, by a tee union twice oil circuit of two rotary motors is collaborated into oil circuit one.
Described tributary drain line and interflow drain line are polymerizable material or metal material.
Described connecting plate is square or circular or oval, and material is metal.
Described connecting plate is fixed on the turntable by welding or screw.
The beneficial effects of the utility model are: the drain oil of rotary motor is guided to the place that is fit to operation, increased the space of the operation of draining the oil, reduced the difficulty of the operation of draining the oil, reduced the time of draining the oil; Owing to drain the oil the mouth of pipe vertically downward, thus the process lubricant oil that guaranteed to drain the oil can splash to turntable, reduced the probability that pollutes board, effectively protected the environment around the board.
Description of drawings
Fig. 1 is the structural representation of the two rotary motor jettison gears of excavator;
Fig. 2 is the STRUCTURE DECOMPOSITION schematic representation of jettison gear shown in Figure 1;
Fig. 3 is the implementation result figure of jettison gear shown in Figure 1.
Among the figure: 1, tributary drain line, 2, pipe joint, 3, tee union, 4, the interflow drain line, 5, connecting plate, 6, cross the wall joint, 7, nut, 8, plug.A, B: rotary motor, C: turntable, D: the two rotary motor jettison gears of excavator.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The two rotary motor jettison gears of excavator, as Fig. 1～shown in Figure 3, comprise drain line, plug 8, comprise pipe joint 2 in addition, described pipe joint 2 one ends are installed on the drain oil of rotary motor A, the other end links to each other with a person in charge of tee union 3, and another person in charge of tee union 3 is connected on the drain line 4 of interflow, the arm of tee union 3 links to each other with tributary drain line 1, and the other end of tributary drain line 1 is connected on the drain oil of another rotary motor B, by a tee union twice oil circuit of two rotary motors is collaborated into oil circuit one, has saved the space, simplified the pipeline of draining the oil, the material of tributary drain line 1 and interflow drain line 4 can the selective polymer material, as rubber or other polymer materials, also can be metal material.Above-mentioned interflow drain line 4 one ends connect tee union 3, the other end was connected on the wall joint 6, and described wall joint 6 excessively passes connecting plate 5 and links to each other with nut 7, for convenient fixing, connecting plate 5 can be designed to square or circular or oval, its material is metal, if select other materials, then is not easy to fix, connecting plate 5 is connected on the turntable C by welding or screw, the position of concrete welding with easy-to-operat, and does not influence turntable work and is advisable.Above-mentioned nut 7 uses plug 8 shutoff.
The utility model is achieved in that as shown in Figures 2 and 3, earlier pipe joint 2 is installed on the drain oil of rotary motor A, a person in charge of ready tee union 3 is connected to pipe joint 2, another is responsible for and then is connected on the drain line 4 of interflow, arm with tee union 3 is connected on the tributary drain line 1 again, and arm drain line 1 is connected on the drain oil of rotary motor B, arrive this, the drain the oil merging process installation of pipeline, below pipeline is fixed, used welding or screw to be connected on the turntable C connecting plate 5, cross wall joint 6 and pass connecting plate 5, one end connects interflow drain line 4, the other end connects nut 7, uses plug 8 with in nut 7 shutoff, so far at last, realize the installation process of jettison gear, be this jettison gear as the D among Fig. 3.
When using this jettison gear; do not need operator to enter below the motor; and only need remove the operation that to realize draining the oil to the plug 8 of oil circuit end; so the space of operation becomes big, and operation easier has reduced, and labor intensity has reduced; and; because fuel outlet is vertically downward, so can not pollute body because of oil spout, effectively protected board environment on every side.
