Embodiment
The present invention relates to a kind of movable bridge gear rack actuating device, it is adaptable to which single span formula and vertical turn on of double-span are opened
Bridge.It is single across folding need 2 gear rack actuating devices complete jointly.
Embodiment 1：As depicted in figs. 1 and 2, by driving gear 1, driven gear 2, guider 3, rack 4, halo 5, outer
Shell 6, inner casing 7, hinged support 8, reduction box 9 are constituted with motor 10.Motor 10 is connected with reduction box 9, reduction box 9 and driving tooth
Wheel 1 is connected, and driving gear 1 is connected with driven gear 2, and driven gear 2 is connected with rack 4, and rack 4 is connected with halo 5, halo 5
It is connected with inner casing 7, inner casing 7 is connected with hinged support 8, guider 3, hinged support 8 is connected with shell 6, and the side of shell 6 is through bolt
Fixed with bridge column 11.Its operation principle is as follows：Motor 10 through reduction box 9 drive driving gear 1, driving gear 1 drive from
Moving gear 2, then drives single-side rack 3 to stretch, and drive axle is opened and closed.Halo 5 passively rotates, and play supporting role.Halo by axle,
The parts such as bearing are connected with inner casing, and two travelling gears are connected by parts such as respective axle and bearings with inner casing, form transmission case,
Fixed, be hinged between transmission case and shell 6 by hinged support 8 with bridge column 11 through bolt by shell 6, can be around vertical perpendicular to bridge
Post Plane Rotation, inner casing has rack guider 3, rack and travelling gear center line is always to maintain vertically.Guider 3 can
Ensure vertical normal engagement at rack-and-pinion, it is ensured that the correctness of transmission.
With reference to Fig. 3, because among the process that bridge is opened, the position moment of rack 4 is all changing, normal in order to ensure
Opening process, it is desirable to which gear rack actuating device can do the independent rotational movement relative to bridge column, it is therefore desirable to be oriented to dress
Put.The operation principle of guider is as follows：The two sides of transmission case 16 are symmetrically distributed with hinged support 8, and hinged support 8 is assemblied in spherical ball
On bearing 6, felt collar oil sealing 15 is arranged in hinged support 8, is sealed, end cover 3 is connected with fulcrum bearing end cap 2, passes through
Fulcrum bearing end cap 2 is connected by bolt with fulcrum bearing outer end cap 1 with shell 6, and the side of shell 6 is fixed on bridge column 11.
During whole unlatching, the part of shell 6 is remained stationary as, and whole transmission case 16 is done around the rotation centerline shown in Fig. 3 to be rotated
Motion, its track is confirmable.Because the reduction box 9 shown in the side of transmission case 16 and Fig. 1, motor 10 are connected, therefore,
The ledge of this side of transmission case 16 is motion relative to shell, so needing on shell, is opened with hinged support for the center of circle
One section of arc groove, to ensure the movement locus of transmission case.
