Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and particularly relates to a straight-connected row of bridges. Background Art

[0002] In recent years, with the continuous growth of China's construction industry and the continuous improvement of the degree of electrical equipment and intelligence, the amount of electrical wiring used has increased. During the construction process, when installing bridges in electrical engineering, it often happens that one or more of the main row of bridges need to be connected to the lateral branch bridges. In the traditional branch connection of the row of bridges, after increasing the connection height by bending twice (that is, bending the main bridge once and the branch bridge once), the branch bridge and the main bridge are connected up and down through a tee connection pipe rack or a cross connection pipe rack. Content of the Utility Model

[0003] In view of the above problems, the purpose of the utility model is to provide a straight-connected row of bridges, which is provided with a connecting frame with a height increasing surface embedded in the main row of bridges. The lower end of the connecting frame is connected to the main bridge, and the upper end of the connecting frame forms a connection with the branch bridge, avoiding the need for bending of the main bridge and the branch bridge, with low construction cost and high construction efficiency.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A straight-connected row of bridges includes a main bridge, a branch bridge, and a cross connector. The main bridge is composed of a plurality of main bridge supports arranged in a row. The branch bridge is longitudinally arranged on the main bridge. The branch bridge is vertically crossed and attached to the main bridge support. The cross connector includes a U-shaped pipe shell. At least one side of the upper end of the U-shaped pipe shell is longitudinally provided with a bridge branch port. The outer end of the bridge branch port is connected to one end of the branch bridge.

[0006] Further, the outer end of the bridge branch port is relatively attached to one end of the branch bridge. The outer circumference of the relatively attached bridge branch port and the branch bridge is nested with a U-shaped connecting piece.

[0007] Further, at least one side of the upper end of the U-shaped pipe shell is longitudinally provided with a height increasing surface. The inner side of the height increasing surface is provided with a groove-shaped flared opening extending outward. The port of the bridge branch port is connected to the port of the groove-shaped flared opening.

[0008] Further, the U-shaped connecting piece is suspended on the main bridge support.

[0009] Further, the included angle between the bottom surface of the groove-shaped flared opening and the height increasing surface is 30°.

[0010] Further, the U-shaped tube shell is welded to the branch bridge, and the U-shaped connecting piece is welded to the outer periphery of the bridge branch opening and the branch bridge.

[0011] Further, the raised surface is a trapezoidal surface.

[0012] Further, the cross-sections of the main bridge support and the branch bridge are both U-shaped structures.

[0013] Due to the above technical solutions adopted by the present utility model, it has the following advantages and effects:

[0014] (1) For the straight connection type row bridge of the present utility model, by embedding the cross-connecting piece in the main bridge support, the upper end of the cross-connecting piece 3 is raised and then extended out of the bridge branch opening and connected to the branch bridge, avoiding the situation that the traditional three-way support or four-way support cannot avoid the bending of the main bridge and the branch bridge, and solving the problems that the bending of the bridge requires a large space or cannot be bent.

[0015] (2) For the straight connection type row bridge of the present utility model, since the main bridge and the branch bridge do not need to be bent, not only the raw materials for manufacturing the main bridge and the branch bridge are saved, but also a large amount of cables can be saved during the later laying of cables in the bridge, and it is convenient for cable threading, which not only reduces the construction cost, but also improves the construction efficiency.

[0021] The following will describe the embodiments of the present utility model in detail with reference to the drawings, so as to more clearly understand the purpose, features and advantages of the present utility model. It should be understood that the embodiments shown in the drawings are not limitations on the scope of the present utility model, but only to illustrate the essential spirit of the technical solution of the present utility model.

[0022] Embodiment 1

[0023] AsFigure 1 - Figure 2 As shown in the figure. This embodiment provides a straight-connected row of cable trays, including a main cable tray, a branch cable tray 2, and a cross-connector 3. The main cable tray is composed of a plurality of main cable tray supports 1 arranged in a row. A branch cable tray 2 is provided on the main cable tray. The branch cable tray 2 is vertically crossed and in close contact with the main cable tray support 1. The cross-connector 3 includes a U-shaped shell 34. On both sides of the upper end of the U-shaped shell 34, there are cable tray branch ports 33. The outer ends of the cable tray branch ports 33 are connected to one end of the branch cable tray 2.

[0024] Specifically, a plurality of main cable tray supports 1 are welded side by side in sequence to form the main cable tray. The ends of a pair of branch cable trays 2 are relatively spaced apart and arranged on the main cable tray supports 1 across the main cable tray. The U-shaped shell 34 is embedded on the main cable tray support 1 between the pair of branch cable trays 2. The cable tray branch ports 33 are located on the outer side of the upper end of the main cable tray support 1 and extend tangentially outward to connect the ends of the branch cable tray 2, thereby realizing the support of the main cable tray support 1 by the branch cable tray 2. The branch cable tray 2 and the cross-connector 3 form a cross-shaped connection.

[0025] Furthermore, the outer ends of each cable tray branch port 33 are in relative close contact with one end of the branch cable tray 2. A U-shaped connecting piece 4 is nested on the outer peripheries of the relatively closely contacted cable tray branch port 33 and the branch cable tray 2. The cable tray branch port 33 and the branch cable tray 2 have the same outer dimensions. After the cable tray branch port 33 and the branch cable tray 2 are relatively closely contacted, their inner and outer peripheral surfaces are flush. The U-shaped connecting piece 4 wraps and nests the ends of the cable tray branch port 33 and the branch cable tray 2 to realize the connection between the cross-connector 3 and the branch cable tray 2.

[0026] Furthermore, on the longitudinal two sides of the upper end of the U-shaped shell 34, there are respectively raised surfaces 32, and the raised surfaces 32 are trapezoidal surfaces.

[0027] On the inner side of the middle of each raised surface 32, there is a groove-shaped flared opening 31 extending outward. The ports of a pair of cable tray branch ports 33 are respectively connected to the ports of the groove-shaped flared opening 31. The groove-shaped flared opening 31 forms a transition connection between the cable tray branch port 33 and the U-shaped shell 34. The groove-shaped flared opening 31 can increase the connection strength between the cable tray branch port 33 and the U-shaped shell 34. At the same time, the setting of the groove-shaped flared opening 31 facilitates the cable to be laid from the main cable tray support 1 and penetrate into the branch cable tray 2. By raising the cable tray branch port 33 through the raised surface 32 to connect the branch cable tray 2, the side main cable tray can be avoided.

[0028] Furthermore, the U-shaped connecting piece 4 is suspended on the main cable tray support 1. The cross-section of the main cable tray support 1 is a U-shaped structure. The connected ends of the cable tray branch port 33 and the branch cable tray 2 are located above the U-shaped structure, and the U-shaped connecting piece 4 is located above the U-shaped structure to nest and wrap the ends of the cable tray branch port 33 and the branch cable tray 2.

[0029] Further, the angles between the bottom surface and the two side surfaces of the trough-shaped bell mouth 31 and the raised surface 32 are both 30°. The large-mouth end of the trough-shaped bell mouth 31 is connected to and penetrates through the raised surface 32, and the small-mouth end of the trough-shaped bell mouth 31 is integrally connected to the bridge branch port 33 to meet the minimum spacing connection.

[0030] Further, the U-shaped shell 34 is welded to the branch bridge 2, the U-shaped connecting piece 4 is welded to the outer peripheries of the bridge branch port 33 and the branch bridge 2, and the trough-shaped bell mouth 31 is welded to the raised surface 32, and the welds of the welding only need to meet the specification requirements.

[0031] Embodiment 2

[0032] See Figure 3 - Figure 4 , different from Embodiment 1, there is one branch bridge 2 in Embodiment 2. A raised surface 32 is provided on one side of the U-shaped shell 34 of the cross-connecting member 3, and a trough-shaped bell mouth 31 and a bridge branch port 33 are provided on the raised surface 32. The branch bridge 2 is connected through the bridge branch port 33 on one side. The branch bridge 2 and the cross-connecting member 3 form a T-shaped connection.

[0033] When the present utility model is specifically implemented, the main bridge is horizontally laid. After the cross-connecting member 3 connects the main bridge support 1 and the branch bridge 2, cables are laid. The branch cables are turned out at the bridge branch port 33. When the branch cables enter the branch bridge 2 from the main bridge support 1, they are lifted by the trough-shaped bell mouth 31 at the side bridge raised surface 32 of the cross-connecting member 3 and then penetrate through. After the cable laying is completed, a bridge cover plate is installed on the main bridge support 1.

[0034] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
