The specific embodiment
Below in conjunction with the specific embodiment, the present invention is elaborated.
As shown in Figure 1, forward shovel hoisting rope protection guiding supporting roller bracket device of the present invention, comprising: roller rack 1, and carrying roller 2, base 3, its middle idler roller 2 is two.Roller rack 1 is installed on base 3.Base 3 is installed on forward shovel canopy top front end.
As shown in Figure 2, by two installing plates 31, roller rack 1 is arranged between the both sides of base 3, installing plate 31 is with bolts with base 3, therefore can adjust by adjusting installing plate 31 and the relative position of base 3 height of carrying roller 2.
As shown in Figure 3,4, described roller rack 1, comprises two side plates 11, connects the connection channel-section steel 12 of two side plates 11, and reinforcing rib 13 is connected channel-section steel 12 tops with two clamping groove plate 14 and clamping groove plates 15 that are placed in centre that are placed in end of draw-in groove with being installed on.
Connect channel-section steel 12 with respect to roller rack 1 inclination certain angle after with side plate 11 welding, make to be welded on the clamping groove plate 14 that connects on channel-section steel 12 and 15 L-type draw-in groove inclination certain angle, thereby be subject to steel cable active force and the self gravitation effect lower roller shaft 21 ends bottom in L-type draw-in groove always, thereby can by L-type draw-in groove, be blocked and prevent that it from can not eject from draw-in groove.Owing to connecting channel-section steel 12, be obliquely installed simultaneously, be also convenient to carrying roller 2 and be installed on support 1.
Reinforcing rib 13 is parallel to connection channel-section steel 12 bearing of trends and is welded in connection channel-section steel 12 inner sides, guarantees the rigidity of roller rack.
