Abstract
The utility model discloses a novel oil injection device of an excavator swing mechanism, belonging to the technical field of an oil injection lubrication device. The oil injection device comprises an oil cup and an oil pipe assembly; wherein the device further comprises an T-shaped joint and a locking nut; the T-shaped joint is inserted into a hole of a front baffle; the locking nut is screwed down at the tail part of the T-shaped joint; the oil cup is arranged at the top end of the T-shaped joint; the oil pipe assembly is arranged at the bottom end of the T-shaped joint. The novel oil injection device has the beneficial effects that the oil injection device is transited by the T-shaped joint, and fixed and sealed by the locking nut; when a screw hole of the T-shaped joint is damaged, only the T-shaped joint is necessary to exchange, in this way, the device is convenient to repair on site so as to greatly reduce the repairing time and save the repairing cost.
Description
Technical field
The utility model relates to a kind of oiling device, specifically is the novel oiling device of a kind of digger revolving mechanism, belongs to oil injecting lubricating device technique field.
Background technology
Excavator will frequently turn round action in the course of the work, the slew gear butter of will often annotating is lubricated, to improve the application life of slew gear.Since want frequent oiling, filling for ease, and refueling device is generally all preposition, makes things convenient for oiling.Whole oiling device is installed and is seen Fig. 1, and oiling device form of structure commonly used is as shown in Figure 3, processing one through hole earlier on front apron, and each thread mill drilling of side in the front and back in hole then, front end screws in the lubricating cup rear end and screws in the oil filling pipe assembly.This structure is simple relatively, but has defective, excavator industrial and mineral more complicated; In case reasons such as lubricating cup and joint are collided cause the screwed hole on the front apron impaired; Seal failure, field maintenance are very inconvenient, poorly realize because limited space is made screw thread more again.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of digger revolving mechanism novel oiling device, and simple in structure, field maintenance is convenient and swift.
To achieve these goals; The technical scheme that the utility model adopts is: the novel oiling device of a kind of digger revolving mechanism, comprise lubricating cup and oil pipe assembly, and also comprise T junction and locking nut; T junction penetrates in the front plate hole; Locking nut tightly is rotated with and fixes on the T junction afterbody, and oil-cup device is on the T junction top, and the oil pipe assembly is installed in the T junction end.
Further, the T junction afterbody is provided with external screw thread, and inside is through hole, and the two ends of through hole are equipped with internal thread.
Further, locking nut and T junction are fastening is sealing device.
The beneficial effect of the new shape of this practicality is: through T junction transition and locking nut fixing seal, as long as when destroying appears in the screwed hole of T junction, change T junction, field maintenance is convenient, reduces maintenance time and maintenance cost greatly.
Description of drawings
Fig. 1 is an existing digger revolving mechanism oil injection structure sketch map;
Fig. 2 is the utility model structure I enlarged diagram;
Fig. 3 is original oil injection structure sketch map.
Among the figure: 1, lubricating cup, 2, T junction, 3, locking nut, 4, the oil pipe assembly, 10, front apron, 20, slew gear.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
As depicted in figs. 1 and 2; The novel oiling device of a kind of digger revolving mechanism comprises lubricating cup 1 and oil pipe assembly 4, also comprises T junction 2 and locking nut 3; T junction 2 penetrates in front apron 10 holes; Locking nut 3 tightly is rotated with and fixes on T junction 2 afterbodys, and lubricating cup 1 device is on T junction 2 tops, and oil pipe assembly 4 is installed in T junction 2 ends; T junction 2 afterbodys are provided with external screw thread, and inside is through hole, and the two ends of through hole are equipped with internal thread; Locking nut 3 and T junction 2 are fastening to be sealing device.
10 processing unthreaded holes on front apron, T junction 2 penetrates unthreaded hole, and it is fastening to carry out between centers with locking nut 3 through external screw thread then; T junction 2 afterbodys are provided with external screw thread, and inside is through hole, the two ends machining internal thread of through hole; Lubricating cup 1 is connected with T junction 2 tops through internal thread; Oil pipe assembly 4 and T junction 2 are connected by internal thread, and lubricating cup 1 is connected with locking nut 3 through T junction 2 with oil pipe assembly 4, thereby realizes the oil injecting lubricating function.As long as when destroying appears in the screwed hole of T junction, change T junction 2, just more convenient when keeping in repair like this, can reduce maintenance time and maintenance cost greatly.
