The specific embodiment
A lot of details have been set forth in the following description so that fully understand the utility model.But the utility model can be implemented much to be different from alternate manner described here, those skilled in the art can do similar popularization under the situation of the utility model intension, so the utility model is not subjected to the restriction of following public specific embodiment.
Please be simultaneously referring to Fig. 2～Fig. 4, the structural representation of expression the utility model guide wheel assemblies.This guide wheel assemblies 300 mainly is made of roller 32 and roller Connection Block 31, and wherein: roller Connection Block 31 is " U-shaped " structure, and roller 32 is rotatably installed on this roller Connection Block 31 by wheel shaft 36, below further is described.
As Fig. 2～shown in Figure 4, roller 31 in the present embodiment can be nylon material and makes, it comprises the first guiding round table surface (or circular conical surface) 3201, transition circle cylinder 3202, the second guiding round table surface 3203, wherein: the first end face circle contour line of transition circle cylinder 3202 coincides with the bottom surface circle contour line of the first guiding round platform 3201, and the second end face circle contour line of transition circle cylinder 3202 coincides with the bottom surface circle contour line of the second guiding round table surface 3203; The first guiding round table surface 3201 and the second guiding round platform 3203 are symmetrical in a vertical plane of roller central axis, and the axis of the axis of the first guiding round table surface 3201 and the second guiding round table surface 3203 coincides with the roller central axis respectively, and angle is acute angle between first end of the bus of the first guiding round table surface 3201 and roller central axis, and angle is acute angle between the bus of the second guiding round table surface 3203 and second end of roller central axis.Constitute V-type roller 32 thus, wherein: the first guiding round table surface 3201, the second guiding round table surface 3203 can lead on two inwall planes of column (can be quarter bend or other prismatic pipe) 100 as spigot surface simultaneously; Transition circle cylinder 3202 does not contact the inner cavity surface of column 100, prevents that the inner chamber bight weld seam of column 100 from impacting.
In the present embodiment, angle between second end of the angle between the bus of the first guiding round table surface 3201 and first end of roller central axis, the bus of the second guiding round table surface 3203 and roller central axis can be respectively 45, make the edge of two buses meet at right angles perpendicular to the line of vision orthogonal projection of roller central axis like this, can adapt to the installation requirement of rectangle column 100 thus.Be understandable that, column 100 for other cross sectional shape (as regular hexagon), the angle of the guiding of first in the roller 32 round table surface 3201, second guiding round table surface 3203 buses and roller central axis needs corresponding adjustment, to guarantee that they can lead on two inwall planes of column 100 simultaneously, repeat no more.
As Fig. 2～shown in Figure 4, roller 32 is installed on " U-shaped " roller Connection Block 31, its basic matching requirements are: roller 32 is located in " U-shaped " groove, wheel shaft 36 is rotatably installed on the roller Connection Block 31, and the first guiding round table surface 3201 of roller 32 and the second guiding round table surface 3203 exceed the end face of roller Connection Block 31 respectively at least in part, can contact the adjacent inner wall plane of column 100 with two spigot surfaces that guarantee roller 32.
In the present embodiment, roller Connection Block 31 is made of base plate 3101 and first, second side plate 3102, and wherein: first, second side plate 3102 is welded on respectively on the base plate 3101, constitutes " U-shaped " support thus and wherein holds roller 32; Offer mounting hole above first, second side plate 3102, so that the wheel shaft 36 of carrying roller 32; Offer mounting hole on the base plate 311, in order to be installed on clump weight 200 or other external device by fasteners such as bolt 8, plain cushion 9, bullet pads 10.When roller 32 was in place, two spigot surface can partly expose to outside this " U-shaped " support, can make two spigot surfaces can both touch the adjacent inner wall plane of column 100 thus.
As Fig. 2～shown in Figure 4, the concrete mounting structure of roller 32 is: roller 32 is supported on the wheel shaft 36 by first, second bearing 37, in the mounting hole of the two end supports of this wheel shaft 36 on first, second side plate 312.In the draw-in groove of wheel shaft 36, insert clamp 35 again, with hexagon socket cap head screw 311 and bullet pad 312 clamp 35 is fixed on the side plate 3102 then, so just realized the location of wheel shaft 36.Certainly, wheel shaft 36 also available other Assembly of pin carries out axial location, repeats no more.
As shown in Figure 4, some spacers are installed on the wheel shaft 36, long spacer 33 wherein is installed between the adjacent bearing 37, short spacer 34 is installed between bearing 37 and the side plate 3102, the equilibrium that keeps first, second bearing 37 positions thus makes roller 32 that axial slip not take place, and guarantees roller 32 stability of rotation.
The guide wheel assemblies 300 of above-described embodiment adopts the roller of V-type spigot surface, and two spigot surface can lead on column adjacent inner wall plane simultaneously, helps to optimize device structure, improves equipment performance, and reduces manufacturing cost.This guide wheel assemblies 300 goes for various application occasions, below is that example further describes with the counterweight guiding mechanism.
Referring to Fig. 5, the structural representation of expression the utility model counterweight guiding mechanism.In this counterweight guiding mechanism, clump weight 200 is loaded in the inner chamber of prismatic column, a plurality of guide wheel assemblies 300 are installed on the clump weight 200, concrete installation requirement is: each guide wheel assemblies 300 all is positioned at the bight of prismatic column, wherein first of the roller guiding round table surface 3201, the second guiding round table surface 3202 contact the adjacent inner wall face of this prismatic column respectively, realize two-sided guiding thus.
As shown in Figure 5, the prismatic column is quarter bend 100, arranges two guide wheel assemblies 300 on the diagonal line of its cross-sectional plane, specifically is the top that each guide wheel assemblies 300 is installed in clump weight 200.With two guide wheel assemblies 300, just can realize the effect of four guide wheel assemblies in original scheme like this, save the quantity of guide wheel assemblies thus, reduce manufacturing cost, also be convenient to carry out layout, also comparatively attractive in appearance on the product appearance.
In the technical scheme that above counterweight guiding mechanism adopts, the roller 32 of guide wheel assemblies 300 adopts V-structure, and it acts on two planes of quarter bend column, so have following technical characterstic simultaneously:
