Abstract
The utility model discloses a drainage mechanism for a counter weight of an excavator, and belongs to the field of lifting equipment of engineering machinery. The drainage mechanism comprises a counter weight mechanism, a lifting hole, a screw plug and a semi-open drainage channel, the screw plug is in thread fit with the lifting hole, and the drainage channel is arranged on the periphery of the lifting hole. After the excavator is lifted, the screw plug in thread fit with the lifting hole is arranged at the lifting hole, and liquid such as rainwater and cleaning agent is prevented from being accumulated at the lifting hole when the lifting hole is unused, so that a thread of the lifting hole is protected from rusting. Besides, the semi-open drainage channel is arranged on the periphery of the lifting hole, liquid accumulation on the periphery of the lifting hole is similarly avoided, further, the service efficiency of the lifting hole of the counter weight mechanism is improved, and the service life of the lifting hole is prolonged.
Description
Technical field
The utility model relates to a kind of drainage mechanism, and a kind of drainage mechanism of counter weight of excavator specifically belongs to the weighing device field of engineering machinery.
Background technology
The producer of present known production excavator, exist serious draining defective at weight member, in liquid buildup such as the hole for hoist place rainwater on counterweight table plane and cleaning agents, can't get rid of, thereby cause screwed hole and periphery corrosion to occur, affect the use of balance weight mechanism.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of drainage mechanism of counter weight of excavator, avoids liquid buildup, improves service efficiency and the application life of hole for hoist.
To achieve these goals, the technical solution adopted in the utility model is: a kind of drainage mechanism of counter weight of excavator comprises balance weight mechanism and hole for hoist, also comprise screw plug and rhone, screw plug and hole for hoist threaded engagement, rhone is semi open model, is arranged on around the hole for hoist.
The utility model at the screw plug of hole for hoist setting and its threaded engagement, has avoided hole for hoist the situation of the liquid buildup such as rainwater and cleaning agent to occur after not using after excavator lifting is finished, thereby the screw thread of having protected hole for hoist can corrosion; The rhone of semi open model is set around hole for hoist simultaneously, guarantees that the periphery of hole for hoist liquid buildup can not occur equally, further improved service efficiency and the application life of hole for hoist in the balance weight mechanism.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Among the figure: 1, balance weight mechanism, 2, hole for hoist, 3, screw plug, 4, rhone.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1: to achieve these goals, the technical solution adopted in the utility model is: a kind of drainage mechanism of counter weight of excavator, comprise balance weight mechanism 1 and hole for hoist 2, also comprise screw plug 3 and rhone 4, screw plug 3 and hole for hoist 2 threaded engagement, rhone 4 is semi open model, is arranged on around the hole for hoist 2.Can not be worn when being that for the screw thread that guarantees hole for hoist 2 screw plug 3 cooperates, it is material that screw plug 3 adopts nylon.
In the course of the work, after the excavator lifting is finished, hole for hoist 2 arranges the screw plug 3 with its threaded engagement, the rhone 4 of semi open model is set around hole for hoist 2 simultaneously, guarantee that hole for hoist 2 peripheries inner and hole for hoist 2 liquid buildup can not occur, thus further improved hole for hoist 2 in the balance weight mechanism 1 service efficiency and application life.
