Abstract
The utility model discloses an improved coal feeder crank and belongs to the technical field of coal feeder cranks. The improved coal feeder crank comprises a connecting shaft and a connecting plate, the connecting shaft and the connecting plate are formed integrally. The improved coal feeder crank has the advantage that the connecting plate and the connecting shaft which are integrally molded main original strength, does not reduce toughness and plasticity of the crank, impact resistance of the connecting shaft is enhanced greatly, and safety is improved.
Description
Technical field
The utility model relates to a kind of improved coal-feeding conveyer crank, belongs to coal-feeding conveyer crank technical field.
Background technique
Existing coal-feeding conveyer crank mechanism, be formed by connecting (as shown in Figure 1) by welding manner by coupling shaft 1 and connecting plate 2, reach requirement though can guarantee the intensity of coal-feeding conveyer crank, but its plasticity and toughness all significantly descend, directly have influence on the effect of welding, welding residual stress, Welding Angular Deformation and dislocation or stress can occur and the phenomenon such as concentrate, so in running, load and impact capacity that it bears descend to some extent, the phenomenon of coupling shaft 1 and connecting plate 2 fractures occurs easily, cause the accident.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of improved coal-feeding conveyer crank, improves toughness and the plasticity of crank, improves its load that bears and impact capacity, guarantees Security.
To achieve these goals, the technical solution adopted in the utility model is: a kind of improved coal-feeding conveyer crank, comprise coupling shaft and connecting plate, and coupling shaft and connecting plate are one-body molded.
Further, connecting plate is provided with two through holes, and the thickness of connecting plate is 25mm.
The beneficial effects of the utility model are: integrated connecting plate and coupling shaft, both kept original intensity, and do not reduce again toughness and the plasticity of crank, the impact resistance of coupling shaft part is greatly strengthened, improve Security.
Description of drawings
Fig. 1 is the structural representation of existing coal-feeding conveyer crank mechanism;
Fig. 2 is structural representation of the present utility model.
Among the figure: 1, coupling shaft, 2, connecting plate.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 2, the utility model comprises coupling shaft 1 and connecting plate 2, and coupling shaft 1 and connecting plate 2 are one-body molded.Integrated connecting plate 2 and coupling shaft 1 have kept original intensity, toughness and plasticity, and the impact resistance of coupling shaft 1 part is greatly strengthened, and improve Security.Coupling shaft 1 and connecting plate 2 phenomenon of rupture can not occur, have improved Security.
Wherein, connecting plate 2 is provided with two through holes, and the thickness of connecting plate 2 is 25mm, makes crank mechanism in the situation that keeps original form structure, makes coupling shaft 1 and connecting plate 2 processing in aggregates, although processing cost increases to some extent, resulting benefit is more.
