Abstract
An adjustable guide roller apparatus for a telescopic cylinder head comprises a guide wheel seat, a 7-shaped guide wheel support, a guide wheel, a compression spring, an adjusting wheel support and an adjusting wheel. The structure guarantees consistent parallelism between a telescopic cylinder and an arm cylinder axial direction when the guide wheel rolls on a three-arm inner lower plate surface, thereby facilitating stress of the telescopic cylinder; and additionally, through rolling of the adjusting wheel on a four-arm inner side plate and a three-arm inner side plate, the telescopic cylinder is indirectly supported, the telescopic cylinder is prevented from always rotating along the cylinder cross section center in a suspension arm, and the telescopic cylinder is always on the vertical plane of the suspension arm, so that a telescopic steel rope is effectively prevented from twisting.
Description
Technical field
The present invention relates to lorry-mounted crane technical field, be specifically related to a kind of adjustable telescopic cylinder head guiding roller device.
Background technology
The telescoping mechanism of tradition arm, it is all the mode using single telescoping cylinder to add rope row, and in the three single cylinder telescopic booms saving arms and above joint number arm, a guide roller is all fixed with before its telescoping cylinder, when only having three joint arms, entirely this guide roller no matter arm is full reduced or under stretching situation, guide roller lower face rolling in Section three arm all the time.When there being four joint arms or more to save arm, because arm and arm are nested against one another, when arm is full reduced, the leading sheave before telescoping cylinder is on the lower face of innermost layer arm, and now telescoping cylinder is parallel with arm telescopic direction; After arm stretches out, guide roller will save arm lower face from innermost layer and be rolled into lower face in three arms always, and in this case, the roller before telescoping cylinder just has the drop of one or several step, and flexible cylinder head also and then has a drop.There is a tetrad pulley as telescoping cylinder is first, tetrad pulley has three arms stretch out steel rope.Expansion roller head declines, so tetrad pulley declines, it is stressed just not on telescoping cylinder axis that three arms stretch out steel rope, and telescoping cylinder will be subject to larger moment of flexure, and telescoping cylinder itself can only bear axial force, stressed very bad to telescoping cylinder like this.Therefore be badly in need of a kind of new version and solve this problem.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the object of this invention is to provide a kind of adjustable telescopic cylinder head guiding roller device, after arm stretches out, occur that to prevent telescoping cylinder declining appears in arm head, produces larger moment of flexure, thus improves the stability of hoisting arm expansion.
Technical scheme of the present invention is: a kind of adjustable telescopic cylinder head guiding roller device, comprise wheel stand, 7 font guide wheel brackets, track adjusting wheel, Compress Spring, adjusting knurl support, adjusting knurl, it is characterized in that, described wheel stand is welded on flexible cylinder head, wheel stand has two interlaced vertical grooves, i.e. vertical slot and translot, two groove antarafacials intersect, the vertical slot that wheel stand is positioned at vertical surface is provided with the 7 font guide wheel brackets that can slide up and down, the perpendicular ends of 7 font guide wheel brackets is equipped with track adjusting wheel, the horizontal end of guide wheel bracket is equipped with Compress Spring, the other end contact wheel stand of Compress Spring, the horizontal part both sides of 7 font guide wheel brackets all have wedge surface, wheel stand is positioned at the translot of horizontal surface is left and right is respectively equipped with an adjusting knurl support, wherein left adjusting knurl support, right adjusting knurl support also have the wedge surface matched with the wedge surface on 7 font guide wheel brackets, left adjusting knurl support and one end relative with wedge surface on right adjusting knurl support are respectively by left adjusting knurl, right adjusting knurl are housed.
Advantage of the present invention: when structure of the present invention ensure that track adjusting wheel lower face rolls in three arms, remain that telescoping cylinder and arm cylinder axis is parallel all the time, be conducive to the stressed of telescoping cylinder; In addition, by the rolling of adjusting knurl at four arm interior plates and three arm interior plates, indirectly play the effect of supporting telescoping cylinder, avoid telescoping cylinder always to rotate around its cylinder barrel kernel of section in arm, make telescoping cylinder all the time on arm vertical guide, can effectively prevent flexible wire rope twisting like this.

Fig. 2 is the structural representation of wheel stand of the present invention.
Fig. 3 is the constitution diagram that the present invention is arranged on flexible cylinder head.
Detailed description of the invention
Now in conjunction with the following drawings, invention is described in detail.
See Fig. 1, Fig. 2, Fig. 3, wheel stand 2 is welded on flexible cylinder head 1, wheel stand 2 has two interlaced vertical grooves, i.e. vertical slot and translot, two groove antarafacials intersect, the vertical slot that wheel stand 2 is positioned at vertical surface is provided with the 7 font guide wheel brackets 3 that can slide up and down, the perpendicular ends of guide wheel bracket 3 is equipped with track adjusting wheel 4, the horizontal end of guide wheel bracket 3 is equipped with Compress Spring 5, the other end contact wheel stand 2 of Compress Spring 5, to prevent from spring moves, the horizontal part of 7 font guide wheel brackets 3 has wedge surface, the weighing apparatus groove that wheel stand 2 is positioned at horizontal surface is left, an adjusting knurl support is respectively equipped with on the right side, wherein left adjusting knurl support 6, right adjusting knurl support 7 also has the wedge surface matched with the wedge surface on 7 font guide wheel brackets 3, left adjusting knurl support 6 and one end relative with wedge surface on right adjusting knurl support 7 are respectively by left adjusting knurl 8 is housed, right adjusting knurl 9, due to the wedge surface effect of left adjusting knurl support 6 and right adjusting knurl support 7, the downward displacement of 7 font guide wheel brackets 3 can be limited, and by the action principle on inclined-plane, by left adjusting knurl 8, the level of right adjusting knurl 9 is inside and outside mobile, regulate moving up and down of 7 font guide wheel brackets 3.
For four joint arms (five joint arms or higher joint arm principle identical): during beginning, track adjusting wheel 4 on flexible cylinder head is in Section of four arm 10 on lower face, when telescopic boom synchronously stretches out under the effect that telescoping cylinder and rope are arranged, because four arms 10 are nested in inside three arms 11, so wide than four arms of the arm cylinder width of three arms 11, the monolateral thickness sum wanting wide four arms and the monolateral gap of three arms and three arm side plates, is set to d; When track adjusting wheel 4 is rolled in arm side, when adjusting knurl 8,9 is rolled into three arm 11 interior plate faces from four arm 10 interior plate faces, adjusting knurl 8,9 just outwards moves a d distance, and adjusting knurl 8,9 is fixed on adjusting knurl support 6,7, so move outside adjusting knurl support 6,7 wedge surface; Under the effect of spring 5,7 font guide wheel brackets 3 move down L, and track adjusting wheel 4 is fixed on guide wheel bracket 3, so guide wheel bracket 3 moves down, namely adding track adjusting wheel 4 and the centre distance of telescoping cylinder, just compensate for the height L of track adjusting wheel 4 from lower face in lower face in four arms and three arms, by determining the mutual linear relationship of gradient control d and the L of wedge surface, ensure track adjusting wheel 4 in three arms 11 during lower face rolling, maintenance telescoping cylinder is parallel with arm cylinder telescopic direction.
