Description

Technical Field

[0001] The utility model relates to the technical field of bridge manufacturing, and particularly relates to a bridge connection structure. Background Art

[0002] When building a tunnel, cable trays are often used to lay cables. The cable trays are formed by connecting cable tray components end to end. The original cable trays had relatively single functions and were only used for cable laying. With the development of cruise robots, modern cable trays now have an additional function. They are not only used for cable laying but also serve as cruise rails for cruise robots. Carrying cruise robots places higher requirements on the strength and load-bearing capacity of the cable trays, especially at the joints of the cable tray components.

[0003] In the prior art, connection pieces are mostly used to connect and fix the joints of cable tray components. For example, a cable tray structure disclosed in the patent application with the application number CN202321502006.X and the name "An adjustable tunnel lighting cable tray" includes a cable tray body, a protective cover, and a bracket. The protective cover is arranged above the cable tray body. The bracket is U-shaped and can be adjustably sleeved on the outer wall of the cable tray body. A connecting frame is detachably arranged between adjacent cable tray bodies. The connecting frame is slidably sleeved on the outside of the cable tray body. Bolt holes are provided on the side wall of the cable tray body, and a strip-shaped groove is provided on the side wall of the connecting frame. The cable tray body and the side wall of the connecting frame are assembled and connected by a first bolt. However, the connecting frame has very limited improvement in the strength of the joint. Therefore, the connection structure of the cable tray needs to be further improved. Summary of the Utility Model

[0004] The purpose of the utility model is to make up for the above deficiencies and disclose a bridge connection structure to the society that is simple and reasonable in structure and can improve the support at the joint.

[0005] The technical solution of the utility model is realized as follows:

[0006] A bridge connection structure includes cable tray components connected end to end. Guide rails are respectively formed on both sides of the upper end of the cable tray components. A connection piece is arranged between adjacent cable tray components. The shape of the connection piece matches the outer wall of the cable tray component. The connection piece is fixedly attached to the outer side wall of the cable tray component. A support portion is formed at the upper end of the connection piece. The support portion is in supporting cooperation with the lower surface of the guide rail.

[0007] Further measures to optimize the technical solution are as follows:

[0008] As an improvement, a positioning piece is arranged between adjacent cable tray components. An inner cavity is formed in the guide rail. Both ends of the positioning piece are respectively inserted into the inner cavity of the guide rail of the cable tray component. Through the positioning of the positioning piece, the splicing of the guide rails can be made more flat, and the vibration during the movement of the cruise robot can be reduced.

[0009] As an improvement, the cross-section of the positioning member is of a square structure.

[0010] As an improvement, a limiting protrusion is punched inward on the guide rail. The setting of the limiting protrusion can limit the insertion depth of the positioning member and improve the assembly efficiency.

[0011] As an improvement, a plurality of first connection holes are provided on the bridge member, a plurality of second connection holes are provided on the connecting piece, and the bridge member and the connecting piece are fixedly connected by a bolt assembly.

[0012] As an improvement, the first connection hole is a vertically arranged kidney-shaped hole.

[0013] As an improvement, the second connection hole is a horizontally arranged kidney-shaped hole.

[0014] Through the cooperation of the vertically arranged kidney-shaped hole and the horizontally arranged kidney-shaped hole, the fine adjustment of the position of the connecting piece is convenient, and the assembly efficiency can be improved.

[0015] As an improvement, the bolt assembly includes a bolt and a nut that are adapted to each other.

[0016] As an improvement, the bolt includes a bolt head and a threaded section, and a square column section is arranged between the bolt head and the threaded section. The setting of the square column section can prevent the rotation of the bolt after the bolt is inserted, thereby facilitating the connection between the nut and the bolt.

[0017] The advantages of the present utility model compared with the prior art are:

[0018] A bridge connection structure of the present utility model has a simple and reasonable structure. The connecting piece with a matching shape is fixed by being attached to the outer side wall of the bridge member, which increases the bonding property between the connecting piece and the bridge member, and uses the support portion to support and cooperate with the lower surface of the guide rail to improve the supporting force for the guide rail, thereby effectively improving the strength of the connection part.

The term "one" should not be construed as a limitation on the number.

[0031] As Figures 1 to 6 shown, a bridge connection structure includes bridge members 1 connected end to end. Guide rails 11 are respectively formed on both sides of the upper end of the bridge member 1. A connection piece 2 is arranged between adjacent bridge members 1. The shape of the connection piece 2 matches the outer wall of the bridge member 1. The connection piece 2 is fixedly attached to the outer side wall of the bridge member 1. A support portion 21 is formed at the upper end of the connection piece 2. The support portion 21 is in supporting cooperation with the lower surface of the guide rail 11. The above guide rail 11 serves as the moving track of the cruise robot.

[0032] There is a positioning member 3 arranged between adjacent bridge components 1. An inner cavity 11a is formed in the guide rail 11, and both ends of the positioning member 3 are respectively inserted into the inner cavity 11a of the guide rail 11 of the bridge component 1 correspondingly.

[0033] The cross-section of the positioning member 3 is of a square structure. The cross-section of the inner cavity 11a of the corresponding guide rail 11 is also of a square structure. The use of the square structure enables both the upper surface and the side surface of the guide rail 11 to serve as the supporting surfaces for the rollers of the cruising robot. At the same time, when installing the positioning member 3, the installation direction does not need to be considered, making the installation more convenient.

[0034] A limiting protrusion 11b is punched inward on the guide rail 11. The setting of the limiting protrusion 11b limits the insertion depth of the positioning member 3, facilitates assembly, and can improve the assembly efficiency.

[0035] A number of first connection holes 1a are provided on the bridge component 1, and a number of second connection holes 2a are provided on the connecting piece 2. The bridge component 1 and the connecting piece 2 are fixedly connected by a bolt assembly.

[0036] The first connection hole 1a is a vertically arranged waist-shaped hole.

[0037] The second connection hole 2a is a horizontally arranged waist-shaped hole.

[0038] Here, the vertically arranged waist-shaped hole and the horizontally arranged waist-shaped hole are used in cooperation. During installation and fixation, it is convenient to finely adjust the position of the connecting piece 2, which can ensure that the supporting part 21 of the connecting piece 2 is in contact with the lower surface of the guide rail 11 to form a support, and can improve the assembly efficiency.

[0039] As an extension, it is also possible to use a horizontally arranged waist-shaped hole for the first connection hole 1a and a vertically arranged waist-shaped hole for the second connection hole 2a.

[0040] The bolt assembly includes a bolt 41 and a nut 42 that are adapted to each other.

[0041] The bolt 41 includes a bolt head 41a and a threaded section 41b, and a square column section 41c is arranged between the bolt head 41a and the threaded section 41b.

[0042] During connection, after splicing two bridge components 1 together, the connecting piece 2 is attached to the outer surface of the bridge component 1. The threaded section 41b of the bolt 41 passes through the second connection hole 2a on the connecting piece 2 and the first connection hole 1a on the bridge component 1 from the outside to the inside, and after pre-fixing the connecting nut 42; here, due to the setting of the square column section 41c, the bolt 41 can be prevented from rotating after passing through the connection hole, facilitating the connection of the nut 42. Then, adjust the position of the connecting piece 2 so that the supporting part 21 of the connecting piece 2 is in contact with the lower surface of the guide rail 11 for support, and finally tighten the nut 42.

[0043] The above are only the preferred embodiments of the present utility model, and thus do not limit the implementation manners and protection scope of the present utility model. For those skilled in the art, it should be realized that all the solutions obtained by equivalent substitution and obvious changes made by using the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
