Detailed description of the invention
Below in conjunction with detailed description of the invention, 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, carrying roller 2, base 3, its middle idler roller 2 is two pieces.Roller rack 1 is installed on base 3.Base 3 is installed on forward shovel canopy top nose.
As shown in Figure 2, between the both sides by two installing plates 31 roller rack 1 being arranged on base 3, installing plate 31 is with bolts with base 3, therefore can be adjusted the height of carrying roller 2 by adjustment installing plate 31 and the relative position of base 3.
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, reinforcing rib 13, is connected channel-section steel 12 top and is placed in two of draw-in groove the clamping groove plate 15 that the clamping groove plate 14 of end and are placed in centre with being installed on.
Connect channel-section steel 12 to tilt after certain angle relative to roller rack 1 and weld with side plate 11, make the L-type draw-in groove inclination certain angle being welded on the clamping groove plate 14 and 15 connected on channel-section steel 12, thus can be in the bottom of L-type draw-in groove by steel cable active force and self gravitation effect lower roller shaft 21 end always, thus can be blocked by L-type draw-in groove and prevent it from can not eject from draw-in groove.Be obliquely installed owing to connecting channel-section steel 12 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 trend and is welded in inside connection channel-section steel 12, ensures the rigidity of roller rack.
Two pieces carrying roller 2 is arranged on two respectively and is placed in the clamping groove plate 14 of end and is placed between middle clamping groove plate 15.Clamping groove plate 14 and 15 can make of channel-section steel.
As shown in Figure 5, end clamping groove plate 14 have L-type draw-in groove, draw-in groove upper dimension A slightly larger than roll shaft 21 tip diameter C, draw-in groove lower dimension B slightly larger than roll shaft 21 termination seam dimension D.Clamping groove plate 14 is welded in roller rack 1 both sides.
As shown in Figure 6, middle card frid 15 both sides all have identical L-type draw-in groove, this L-type draw-in groove and clamping groove plate 14 to open draw-in groove identical.Clamping groove plate 15 is welded in roller rack 1 centre position.
As shown in Figure 7, carrying roller 2 comprises roll shaft 21, roller 22, bearing 23, back-up ring 24, spacer 25.Roll shaft 21 is arranged with roller 22, roll shaft 21 two ends are arranged with bearing 23, are provided with back-up ring 24 outside bearing 23, are provided with spacer 25 outside back-up ring 24, and bearing 23, back-up ring 24 and spacer 25 are installed in cylinder 22, and cylinder 22 is stretched out at roll shaft 21 two ends.Bearing 23 is GB/T276.Back-up ring 24 is GB/T893, so that install.Carrying roller 2 is unpowered carrying roller, and roll shaft 21 maintains static, roller 22 can roll under external force.
As shown in Figure 8, described roll shaft 21 two ends are all milled with seam plane, and this seam planar section is fixed in L-type draw-in groove.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the present invention.
