Embodiment 1

[0035] see figure 1 , figure 2 , image 3 and Figure 4 As shown, the roller type cable saddle of the present invention is a roller type loose cable saddle, which is arranged in an inclined structure (such as Figure 4 As shown, compared with the horizontal plane, it forms an angle of about a° inclination) on the loose cable saddle foundation at the side span in front of the anchor body. The present invention includes a supporting roller assembly 3 arranged between the saddle body 1 and the base 2 .

[0036] The inside of the saddle body 1 has a loose cable saddle groove formed from top to bottom, and the bottom of the saddle body 1 is connected with an upper bearing plate 11 .

[0037] The base 2 is mainly composed of the embedded grid 23 anchored in the concrete tower body, and the lower bearing plate 21 connected to the top of the embedded grid 23 . The longitudinal ends of the lower bearing plate 21 (corresponding to the arrangement direction of the main cables of th...

Embodiment 2

[0057] Other content of this embodiment is the same as Embodiment 1, the difference is:

[0058] The two ends of each roller supporting the roller assembly are respectively connected with toothed stoppers;

[0059] Correspondingly, the saddle side racks of elongated structure are respectively arranged along the longitudinal direction on both lateral sides of the upper bearing plate at the bottom of the saddle body, that is, the saddle side racks on each side are along the longitudinal length of both ends of the upper bearing plate. Direction forming (it can be segmented butt joint or a whole);

[0060] The lateral sides of the lower bearing plate on the top of the base are respectively provided with seat-side racks of elongated structure along the longitudinal direction, that is, the seat-side racks on each side are formed along the length direction of the longitudinal ends of the lower bearing plate (can be divided segment docking, or it can be a whole).

[0061] In this em...

Embodiment 3

[0063] Other content of this embodiment is the same as embodiment 1 or 2, the difference is:

[0064] The tooth-shaped limiter of the supporting roller assembly is only formed with gear teeth in the top area, and the bottom contour is within the coverage of the outer contour of the end surface of the roller;

[0065] Correspondingly, only the bottom of the saddle body is provided with a toothed rack that engages with the tooth-shaped limiter on the support roller assembly, while the lower bearing plate on the top of the base only forms rolling contact with the rollers of the support roller assembly Fitting, gearless transmission fitting structure.

Abstract

The invention discloses a rolling shaft limiting and supporting structure for a cable saddle of a suspension bridge, which comprises a supporting rolling shaft assembly, at least one rolling shaft of the supporting rolling shaft assembly is provided with a tooth-shaped limiting piece, the tooth-shaped limiting piece is provided with gear teeth formed towards one side of a saddle body and / or towards one side of a base, and the tooth-shaped limiting piece and the rolling shaft keep synchronous movement. A rack meshed with the gear teeth of the tooth-shaped limiting piece is fixed to one side of the saddle body and / or one side of the base, and the bearing rolling shaft assembly achieves reciprocating motion within the allowable displacement range through rotating meshing of the gear teeth of the tooth-shaped limiting piece and the corresponding rack. On the premise that rolling fit between the supporting rolling shaft assembly and the saddle body and / or the base is not affected, self-locking is achieved through meshing of the tooth-shaped limiting pieces on the supporting rolling shaft assembly and the corresponding racks, friction force constraint limiting between the supporting rolling shaft assembly and the saddle body and / or the base under auxiliary heavy loads is achieved, and deviation from the design position is prevented.

Description

technical field [0001] The invention relates to a supporting structure for installing a cable saddle of a suspension bridge, in particular to a roller bearing position-limiting supporting structure for installing a cable saddle of a suspension bridge. Background technique [0002] In the cable saddle installation structure of suspension bridge engineering, the saddle body with saddle groove is generally assembled on the top of the tower body or the base anchored by the top of the anchor block in the form of free movement back and forth (mainly composed of grid frame, lower bearing plate or embedded bottom plate, etc.) to withstand the pressure from the main cable and restrain the vertical and lateral displacement of the main cable, and to adapt to the pushing operation of the saddle on the base during bridge construction, and the swing of the saddle with the main cable , and after the bridge is completed and put into operation, the change of the line shape of the main cable ...
