The specific embodiment
1, adopt the tooth bar engagement to add the adjustment structure of inclined-plane positioning and locking, large-scale length adjustment adopts tooth bar to be engaged with level and regulates, and realizes length step-less adjustment and locking by oblique mechanism then.
2, go up between spherical outside surface seat (20) and the last Internal Spherical Surface bearing (11), following spherical outside surface seat (21) and and following Internal Spherical Surface bearing (5) between be the sphere bearing fit, promptly adopt the spherical bearing connection, but the dislocation spatially of automatic compensation correlated parts.
3, among Fig. 1, anchor slab (13) is fixed on the wall, and upper backup pad (12) lower supporting plate (8) is welded on the anchor slab (13), and last Internal Spherical Surface bearing (11) and following Internal Spherical Surface bearing (5) are separately fixed at the inside, hole on upper backup pad (12) lower supporting plate (8).It is that strut is connected transition apparatus and common multi-form strut body such as masts type, circular rod type that strut connects transition combination (1), multiple strut bodies such as H shaped steel formula connect the integral body that forms by welding manner, length can reach 7,8 meters long, the one end is fixed on the tower machine, and the other end and gusset piece (2) link.Only drawn a part wherein among Fig. 1.
Among Fig. 2, gusset piece (2) is welded on locking bearing (17) and becomes as a whole, length adjustment gear (14) is fixed on the locking bearing (17) by length adjustment gear wheel shaft (16), because the length of different at the construction field (site) struts connection transition combination (1) differs and reaches more than 500 millimeters, at this moment at first to rotate length adjustment gear wheel shaft (16), length adjustment gear (14) and rack bar (4) are meshing with each other, drive locking bearing (17) and move to needed position, this position is determined by the length that strut connects transition combination (1), use attachment pegs (3) that strut is connected transition combination (1) then and be fixed up, finish the length adjustment process with the gusset piece (2) of locking on the bearing (17).
Among Fig. 3, hole on double inclined plane locking rack limit shaft (22) and the double inclined plane locking rack (18) is a bearing fit, the length of double inclined plane locking rack limit shaft (22) goes up the equal in length of slot with locking bearing (17), and the length direction that locking bearing (17) is gone up the length direction rack bar (4) of slot is consistent.The width of double inclined plane locking rack (18) equates with the width that locking bearing (17) is gone up slot, therefore when double inclined plane locking rack (18) insertion locking bearing (17) is gone up slot, in length still is that Width can run-off the straight, double inclined plane locking rack (18) can slide to adjust the insertion position along double inclined plane locking rack limit shaft (22), mesh fully up to the tooth on a certain position and rack bar (4), whether this position can be confirmed with the end face of locking bearing (17) is consistent by the end face of observing double inclined plane locking rack (18), at this moment insert double inclined plane piece (9) respectively at fore-and-aft direction, in the contacted while of inclined-plane of inclined-plane, its underpart and double inclined plane locking rack (18), its side contacts with the sidewall that locking bearing (17) is gone up slot, thereby carries out spacing to double inclined plane locking rack (18).Load onto inclined-plane briquetting (10) after spacing, inclined-plane, its underpart is contacted simultaneously with the upper inclined surface of the double inclined plane piece (9) of fore-and-aft direction, guaranteed the stressed homogeneity of fore-and-aft direction double inclined plane piece (9); Compress inclined-plane briquetting (10) by lock screw (15) then, at this moment connect the integral body that transition combination (1), locking bearing (17), double inclined plane locking rack (18), double inclined plane piece (9), inclined-plane briquetting (10) are constituted by strut, because being meshing with each other of tooth, can't produce relative displacement with rack bar (4), thereby reach the purpose of locking.
Among Fig. 4, between last spherical outside surface seat (20) and following spherical outside surface seat (21) and last Internal Spherical Surface bearing (11) and the following Internal Spherical Surface bearing (5) is the sphere bearing fit, can produce the relative displacement of space any direction, when the hole in the middle of spherical outside surface seat (20) and the following spherical outside surface seat (21) in mandrel (6) insertion, spatial offset on can automatic compensation between Internal Spherical Surface bearing (11) and the following Internal Spherical Surface bearing (5), this with physical construction in very long axle two ends of length to adopt the principle of tilting bearing be consistent.Between rack bar Internal Spherical Surface permanent seat (7) and the rack bar spherical outside surface seat (19) also is the sphere bearing fit, can produce the relative displacement of space any direction, because connecting transition combination (1), strut has 7,8 meters long, when assembling inevitably and produce bigger spatial offset between the locking bearing (17), adopt the method for spherical bearing can automatic compensation spatial offset between the two.
4, the lower bevel of double inclined plane piece (9) contacts with the inclined-plane of double inclined plane locking rack (18), its side contacts with the sidewall that locking bearing (17) is gone up slot, double inclined plane locking rack (18) is meshing with each other by tooth with rack bar (4), go up simultaneously between spherical outside surface seat (20) and the last Internal Spherical Surface bearing (11), following spherical outside surface seat (21) and and following Internal Spherical Surface bearing (5) between be the sphere bearing fit.
5, length adjustment gear (14) links by length adjustment gear wheel shaft (16) and locking bearing (17), and is meshed with rack bar (4).
6, it is as a whole that gusset piece (2) is welded on locking bearing (17) one-tenth, by 2 attachment pegs in front and back (3) strut connected transition combination (1) and link up with gusset piece (2).
7, the upper inclined surface of the double inclined plane piece (9) of the inclined-plane of inclined-plane briquetting (10) and fore-and-aft direction is kept in touch simultaneously.
8, the hole on double inclined plane locking rack limit shaft (22) and the double inclined plane locking rack (18) is a bearing fit, and its length equals to lock the length that bearing (17) is gone up slot.
