Description

Technical Field

[0001] The utility model relates to a cable saddle of a suspension bridge, in particular to a matching structure of an upper bearing plate and a lower bearing plate for a swing shaft type cable saddle. Background Art

[0002] The swing shaft type cable saddle is usually applied to the structure of an earth-anchored suspension bridge. It is arranged on the support platform between the side span and the anchor span to provide support for the main cable, so that the main cable can smoothly change linearly and diverge to the anchor. Due to the existence of the swing shaft type cable saddle in the structure of the earth-anchored suspension bridge, when the bridge deck is subjected to dynamic loads, it is required that the swing shaft type cable saddle supporting the main cable can generate small-angle forward and backward swing displacements along the longitudinal direction of the main cable, so as to balance the force of the whole bridge.

[0003] Therefore, the swing shaft type cable saddle has a cable saddle body and a cable saddle base assembled together. Among them, an upper bearing plate is connected to the bottom of the saddle body, and the bottom surface of the upper bearing plate is a planar structure in the width direction. A lower bearing plate is connected to the top of the base, and the top surface of the lower bearing plate is an arched curved surface structure in the width direction, that is, the top surface of the lower bearing plate is a cylindrical surface structure. In the assembled structure of the saddle body and the base, the upper bearing plate at the bottom of the saddle body is seated on the top surface of the lower bearing plate at the top of the base. After the suspension bridge structure is stressed, the upper bearing plate at the bottom of the saddle body can generate a swing action along the lower bearing plate at the top of the base in the width direction, and this width direction is the longitudinal direction of the erection of the main cable.

[0004] In order to be able to position the relative position between the upper bearing plate at the bottom of the saddle body and the lower bearing plate at the top of the base, and to restrict and limit the swing action of the upper bearing plate on the lower bearing plate, the combined upper bearing plate and lower bearing plate are connected by a plurality of tapered steel pins arranged at intervals in the length direction, that is, a plurality of pin holes are spacedly arranged in the length direction of the upper bearing plate, and a plurality of pin holes are spacedly arranged in the length direction of the lower bearing plate. When the upper bearing plate is correctly seated on the lower bearing plate, the pin holes on the upper bearing plate and the pin holes on the lower bearing plate form a one-to-one corresponding matching relationship with high precision, and high-precision tapered steel pins are inserted into the pin holes of the one-to-one corresponding matching relationship.

[0005] For the above-mentioned matching structure of the upper bearing plate and the lower bearing plate with tapered steel pins inserted, refer to the technologies such as the one named "A Cable Saddle Swing Shaft Structure" with the publication number CN 205653704 U and the publication date of October 19, 2016, and the one named "A Method for Testing the Swing of a Swing Shaft Type Cable Saddle" with the publication number CN106323615 A and the publication date of January 11, 2017, etc. disclosed in Chinese patent documents. The matching structure of the upper bearing plate and the lower bearing plate with tapered steel pins inserted mainly has the following technical problems:

[0006] 1. There are a large number of pin holes with high precision on the upper bearing plate and the lower bearing plate, as well as a large number of tapered steel pins used, which complicate the overall forming structure, make the processing and assembly processes complex, and have a high technical difficulty.

[0007] 2. A large number of pin holes on the upper bearing plate are arranged at intervals along the length direction at the width center of the upper bearing plate; a large number of pin holes on the lower bearing plate are arranged at intervals along the length direction at the width center of the lower bearing plate; when the load borne by the dispersion saddle is large, stress concentration occurs at the width centers of the upper bearing plate and the lower bearing plate respectively due to the large number and dense positions of the pin holes, resulting in fatigue damage and posing a safety risk of cracking along the width center.

[0008] Therefore, the matching structure of the upper bearing plate and the lower bearing plate with the above-mentioned tapered steel pin penetration type has technical problems of complex forming structure and easy fatigue damage, and needs to be improved. Utility Model Content

[0012] At the same end of the upper bearing plate and the lower bearing plate, the end of the upper bearing plate has a gear, and the end of the lower bearing plate has a rack;

[0013] When the upper bearing plate is seated on the top surface of the lower bearing plate through the bottom surface, the gear at the same end meshes with the rack, and when the upper bearing plate swings along the width direction of the lower bearing plate, the gear at the same end rolls and meshes with the rack.

[0014] The gear at the end of the upper bearing plate is a sector gear structure;

[0015] The working tooth edge of the gear is within the width coverage range of the upper bearing plate, and the fixed part of the gear is within the corresponding end face coverage range of the upper bearing plate.

A matching structure of an upper bearing plate and a lower bearing plate for a swing shaft type loose cable saddle, including an upper bearing plate assembled at the bottom of the loose cable saddle body, and a lower bearing plate assembled at the top of the loose cable saddle base;

[0021] When the saddle body is assembled on the base, the upper bearing plate at the bottom of the saddle body is seated on the top surface of the lower bearing plate at the top of the base through the bottom surface;

[0022] At the same end of the upper bearing plate and the lower bearing plate, the end of the upper bearing plate has a rack, and the end of the lower bearing plate has a gear;

That is, by arranging a meshing gear and rack at the same end of the upper bearing plate and the lower bearing plate, the technical purpose of positioning the relative position between the upper bearing plate and the lower bearing plate and restricting and limiting the yaw is achieved. Thus, the conical steel pin between the upper bearing plate and the lower bearing plate can be directly cancelled, that is, the pin holes on the upper bearing plate and the lower bearing plate are directly cancelled, so that the upper bearing plate and the lower bearing plate are formed into an integral structure with high structural strength and good stress stability, eliminating the structures with stress concentration on the upper bearing plate and the lower bearing plate, and further reliably bearing large loads in the suspension bridge structure.

[0037] The present utility model relates to the cable saddle of a suspension bridge, specifically a cooperation structure between the upper bearing plate and the lower bearing plate for a swing-axis type cable saddle. The main technical solutions of the present utility model will be specifically described below in combination with multiple embodiments. Among them, Embodiment 1 is combined with the accompanying drawings of the specification, that is Figure 1 、 Figure 2 、Figure 3 and Figure 4 clearly and detailedly explain the technical solution content of the present utility model; although other embodiments are not separately drawn, their main structures can still refer to the drawings of Embodiment 1.

[0038] It should be particularly noted here that the drawings of the present utility model are schematic. In order to clarify the technical purpose of the present utility model, unnecessary details have been simplified to avoid obscuring the technical solution contributed by the present utility model to the prior art. In addition, expressions such as "about" and "substantially" regarding quantity or mating relationship in the following text mean that reasonable assembly errors, processing errors, etc. in the industry are allowed, rather than literal expressions of absolute quantity or mating relationship.

[0039] Embodiment 1

[0040] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown in [relevant figures], the present utility model is a mating structure of an upper bearing plate and a lower bearing plate for a swing shaft type loose cable saddle, which includes an upper bearing plate 1 assembled at the bottom of the saddle body 5 of the loose cable saddle, and a lower bearing plate 2 assembled at the top of the base 6 of the loose cable saddle. The upper bearing plate 1 is assembled in the embedding groove of the bottom block at the bottom of the saddle body 5, and there is a height difference between its bottom surface and the notch of the embedding groove. In the height direction, the bottom surface of the upper bearing plate 1 is higher than the notch of the bottom block embedding groove, forming an inner sunk assembly; the bottom surface of the upper bearing plate 1 is a planar structure in the width direction and also a planar structure in the length direction. The lower bearing plate 2 is assembled in the embedding groove at the top of the base 6, and there is a height difference between its top surface and the notch of the embedding groove. In the height direction, the top surface of the lower bearing plate 2 is higher than the notch of the embedding groove, forming a raised assembly; the top surface of the lower bearing plate 2 is an arched curved surface structure in the width direction and a straight structure in the length direction, that is, the top surface of the lower bearing plate 2 is a cylindrical curved surface.

[0041] When the saddle body 5 is assembled on the base 6, the upper bearing plate 1 at the bottom of the saddle body 5 is seated on the top surface of the lower bearing plate 2 at the top of the base 6 through its bottom surface. The embedding grooves of the bottom blocks at the bottom of the saddle body 5 surround the top of the lower bearing plate 2 on both sides in the width direction. Of course, an activity gap required for yaw should be formed, and a spacing fit is formed between the bottom of the saddle body 5 and the top of the base 6.

[0042] Between the above-mentioned assembled upper bearing plate 1 and lower bearing plate 2, meshing gears 3 and racks 4 are respectively arranged at both ends in the length direction.

[0043] Specifically, at the same end of the upper bearing plate 1 and the lower bearing plate 2, a gear 3 is connected to the end of the upper bearing plate 1 with multiple screws, and a rack 4 is connected to the end of the lower bearing plate 2 with multiple screws. The gear 3 at the end of the upper bearing plate 1 is of a sector gear structure, and the working tooth edge of its curved diameter contour (referring to the arrangement track of the teeth) is within the width coverage range of the upper bearing plate 1 and does not exceed it, and the working tooth edge of the gear 3 corresponds to the bottom surface of the upper bearing plate 1 and slightly extends downward beyond the bottom surface of the upper bearing plate 1. The fixing part of the gear 3 is within the coverage range of the corresponding end face of the upper bearing plate 1 and does not exceed it. This structure will not interfere with the yaw movement of the upper bearing plate 1 on the lower bearing plate 2 when the gear and rack are engaged, nor will it interfere with the assembly structure of the upper bearing plate 1 at the bottom of the saddle body 5.

[0044] For the rack 4 at the end of the lower bearing plate 2, the working tooth edge of its straight contour (referring to the arrangement track of the teeth) is within the width coverage range of the lower bearing plate 1 and does not exceed it, and the working tooth edge of the rack 4 corresponds to the top surface of the lower bearing plate 2 and is basically flush with the highest point of the top surface of the lower bearing plate 2. The fixing part of the rack 4 is within the coverage range of the corresponding end face of the lower bearing plate 2 and does not exceed it. This structure will not interfere with the yaw movement of the upper bearing plate 1 on the lower bearing plate 2 when the gear and rack are engaged, nor will it interfere with the assembly structure of the lower bearing plate 2 at the top of the base 6.

[0045] When the upper bearing plate 1 is seated on the top surface of the lower bearing plate 2 through its bottom surface, the upper-side gear 3 at the same end meshes with the lower-side rack 4. And when the upper bearing plate 1 generates a yaw movement along the width direction of the lower bearing plate 2, the upper-side gear 3 at the same end rolls and meshes with the upper-side rack 4. That is to say, when the upper bearing plate 1 and the lower bearing plate 2 are in a centered state in the width direction, at the middle part of the gear 3 at the end of the upper bearing plate 1, it forms a complete meshing with the middle part of the rack at the end of the lower bearing plate 2; for the left and right partial teeth of the upper-side gear 3, they respectively form a gradually variable meshing allowance that can roll and mesh with the corresponding left and right partial teeth of the upper-side rack 4. When the upper bearing plate 1 generates a left yaw movement along the width direction of the lower bearing plate 2, the engaged upper-side gear 3 and lower-side rack 4 roll and form a complete meshing at the left side; a gradually variable meshing allowance that can roll and mesh is formed from the middle to the right. When the upper bearing plate 1 generates a right yaw movement along the width direction of the lower bearing plate 2, the engaged upper-side gear 3 and lower-side rack 4 roll and form a complete meshing at the right side, and a gradually variable meshing allowance that can roll and mesh is formed from the middle to the left.

[0046] In this way, through the meshing structure of the above-mentioned gear and rack, the relative position between the upper bearing plate and the lower bearing plate is positioned, and the yaw movement of the upper bearing plate on the lower bearing plate is restricted and limited, replacing the movable yaw structure of the traditional tapered steel pin.

[0047] Embodiment 2

[0048] The other contents of this embodiment are the same as those of Embodiment 1, except that:

[0049] The gear is fixed at the corresponding end of the upper bearing plate by a welding structure;

[0050] The rack is fixed at the corresponding end of the lower bearing plate by a welding structure.

[0051] Embodiment 3

[0052] The other contents of this embodiment are the same as those of Embodiment 1, except that:

[0053] The gear is formed at the corresponding end of the upper bearing plate by an integral molding structure;

[0054] The rack is formed at the corresponding end of the lower bearing plate by an integral molding structure.

[0055] Embodiment 4

[0056] The utility model relates to a matching structure of an upper bearing plate and a lower bearing plate for a swing shaft type loose cable saddle, which comprises an upper bearing plate assembled at the bottom of the loose cable saddle body and a lower bearing plate assembled at the top of the loose cable saddle base. The upper bearing plate is assembled in the embedding groove of the bottom block at the bottom of the saddle body, and there is a height difference between its bottom surface and the notch of the embedding groove. In the height direction, the bottom surface of the upper bearing plate is higher than the notch of the bottom block embedding groove, forming an internal sunken assembly; the bottom surface of the upper bearing plate is a flat structure in the width direction and also a flat structure in the length direction. The lower bearing plate is assembled in the embedding groove at the top of the base, and there is a height difference between its top surface and the notch of the embedding groove. In the height direction, the top surface of the lower bearing plate is higher than the notch of the embedding groove, forming a convex assembly; the top surface of the lower bearing plate is an arched curved surface structure in the width direction and a straight structure in the length direction, that is, the top surface of the lower bearing plate is a cylindrical curved surface.

[0057] When the saddle body is assembled on the base, the upper bearing plate at the bottom of the saddle body is seated on the top surface of the lower bearing plate at the top of the base through its bottom surface, and the embedding grooves of the bottom blocks at the bottom of the saddle body surround the top of the lower bearing plate on both sides in the width direction. Of course, an activity gap required for yaw should be formed, and a spacing fit is formed between the bottom of the saddle body and the top of the base.

[0058] Between the above-mentioned upper bearing plate and lower bearing plate assembled together, gears and racks meshing with each other are respectively arranged at both ends in their length direction.

[0059] Specifically, at the same end of the above-mentioned upper bearing plate and the above-mentioned lower bearing plate, a rack is connected to the end of the upper bearing plate by a plurality of screws, and a gear is connected to the end of the lower bearing plate by a plurality of screws.

[0060] The rack at the end of the upper bearing plate, the working tooth edge of its straight-line contour (referring to the arrangement track of the teeth) is within the width coverage range of the upper bearing plate and does not exceed it, and the working tooth edge of the rack corresponds to the bottom surface of the upper bearing plate and is basically flush with the bottom surface of the upper bearing plate. The fixing part of the rack is within the coverage range of the corresponding end face of the upper bearing plate and does not exceed it. This structure will not interfere with the yaw movement of the upper bearing plate on the lower bearing plate when the gear and rack are engaged, nor will it interfere with the assembly structure of the upper bearing plate at the bottom of the saddle body.

[0061] The gear at the end of the lower bearing plate is a sector gear structure. The working tooth edge of its curved diameter contour (referring to the arrangement track of the teeth) is within the width coverage range of the lower bearing plate and does not exceed it, and the working tooth edge of the gear corresponds to the top surface of the lower bearing plate and slightly exceeds the top surface of the lower bearing plate upward. The fixing part of the gear is within the coverage range of the corresponding end face of the lower bearing plate and does not exceed it. This structure will not interfere with the yaw movement of the upper bearing plate on the lower bearing plate when the gear and rack are engaged, nor will it interfere with the assembly structure of the lower bearing plate at the top of the base.

[0062] When the upper bearing plate is seated on the top surface of the lower bearing plate through its bottom surface, the upper-side rack at the same end engages with the lower-side gear. And when the upper bearing plate makes a yaw movement along the width direction of the lower bearing plate, the upper-side rack at the same end rolls and engages with the lower-side gear. That is to say, when the upper bearing plate and the lower bearing plate are in a centered state in the width direction, the middle part of the rack at the end of the upper bearing plate is fully engaged with the middle part of the gear at the end of the lower bearing plate; the left and right part teeth of the upper-side rack respectively form a gradually variable meshing allowance that can roll and engage with the corresponding left and right part teeth of the lower-side gear. When the upper bearing plate makes a left yaw movement along the width direction of the lower bearing plate, the engaged upper-side rack and lower-side gear roll and form full engagement at the left side; a gradually variable meshing allowance that can roll and engage is formed from the middle to the right. When the upper bearing plate makes a right yaw movement along the width direction of the lower bearing plate, the engaged upper-side rack and lower-side gear roll and form full engagement at the right side, and a gradually variable meshing allowance that can roll and engage is formed from the middle to the left.

[0063] In this way, through the above-mentioned meshing structure of the gear and rack, the relative position between the upper bearing plate and the lower bearing plate is positioned, and the yaw movement of the upper bearing plate on the lower bearing plate is restricted and limited, replacing the movable yaw structure of the traditional tapered steel pin.
