Description

Technical Field

[0001] The utility model belongs to the technical field of bridge frames and relates to a climbing bend with adjustable angle. Background Art

[0002] Cable trays can be installed independently or on various buildings, structures and pipe gallery supports to protect the cables laid inside.

[0003] When the cable tray is set horizontally, the height from the ground is generally not less than 2.5m. When it is laid vertically, the part below 1.8m from the ground should be protected by a tray cover. Positions with height differences require the use of climbing bends to connect the cable trays at both ends to ensure that the internal cables can pass smoothly. The climbing bends in the existing technology are all made according to the design plan by bending and welding the plates. The inclination angle is fixed and cannot be adjusted according to the actual situation during on-site installation and setting, nor can they be prefabricated in advance for stocking, which affects the supply efficiency.

[0004] Therefore, a climbing bend with adjustable angle is proposed. Utility Model Content

[0021] like Figure 1 and Figure 2 As shown, the angle-adjustable climbing bend includes two bridge frames 1. The cross-section of the bridge frame 1 is U-shaped. A base plate 2 is hingedly installed between the bottom walls of the two bridge frames 1. A connecting rod 3 is rotatably installed between the side walls of the two bridge frames 1. A baffle 4 is fixedly installed on the side of the connecting rod 3 away from each other. The connecting rod 3 is located on the inner side of the bridge frame 1, and the baffle 4 is located on the outer side of the bridge frame 1; the end of the connecting rod 3 is located in the middle position of the side wall of the bridge frame 1 in the vertical direction. During the swing adjustment process, the two bridge frames 1 always remain parallel, and the connecting rod 3 and the base plate 2 also always remain parallel. The baffle 4 can block the two sides of the base plate 2 and always remain connected with the two bridge frames 1, thereby continuously protecting the cables placed inside.

[0022] The lower ends of the baffles 4 on both sides are set to arc-shaped edges, and the arc-shaped edges are evenly provided with positioning grooves 5. The side walls of the bridge 1 are provided with positioning components 6 for clamping the positioning grooves 5; the positioning grooves 5 rotate in a circle with the swing of the baffles 4. After the positioning components 6 are clamped with the positioning grooves 5, the tilting posture between the bridge 1 and the baffles 4 can be fixed, and can be adjusted according to actual installation requirements.

[0023] Specifically, a compensation block 10 is fixedly installed between the connecting rod 3 and the baffle 4. The thickness of the compensation block 10 is greater than the thickness of the side wall of the bridge 1. Through the setting of the compensation block 10, a gap can be left between the baffle 4 and the bridge 1 to avoid scratches when the baffle 4 and the bridge 1 swing relative to each other, thereby damaging the protective paint on the surface.

[0024] Specifically, such as Figure 2 As shown, the positioning assembly 6 includes a spring piece 61 and a pin 62. One end of the spring piece 61 is fixedly installed on both sides of the bridge 1, and the other end of the spring piece 61 is fixedly installed with the pin 62. Positioning holes 63 are opened on both sides of the bridge 1; the spring piece 61 is an elastic metal sheet. When the spring piece 61 is pushed outward, the pin 62 can be disengaged from the positioning hole 63 and the positioning groove 5. At this time, the baffle 4 and the bridge 1 can swing relative to each other, and when the spring piece 61 is reset, the pin 62 passes through the positioning groove 5 and engages with the positioning hole 63. At this time, the baffle 4 and the bridge 1 cannot swing relative to each other.

[0025] Specifically, the side wall of the bridge 1 is provided with at least two pairs of elongated holes 12. When the bridge 1 is docked with other straight bridges, docking parts (mainly including connecting plates and bolt groups) can be installed through the elongated holes 12 to complete the connection between the bridges.

[0026] In addition, a bridge cover can be set according to the needs of cable protection, such as Figure 3 As shown, the tops of both sides of the bridge 1 are bent inward to form flanges 11 , and the bridge cover is mounted on the top of the bridge 1 by snapping together with the flanges 11 .

[0027] Specifically, the bridge cover includes two first cover plates 7 and a second cover plate 9. The second cover plate 9 is hinged between the two first cover plates 7. Hooks 8 are fixedly installed at the four corners of the lower surface of the first cover plate 7. The hooks 8 are elastic metal hooks. After the hooks 8 are snap-fitted and assembled with the flanges 11, the first cover plates 7 can be snapped onto the bridge 1 respectively. At the same time, the hinged second cover plate 9 is also located above the base plate 2 to complete comprehensive covering protection.

[0028] The working method of this embodiment is as follows:

[0029] When in use, first connect the bridge frames 1 on both sides with the other straight bridge frames through the docking pieces installed in the long holes 12; after pushing the spring pieces 61 outward, the pins 62 can be disengaged from the positioning holes 63 and the positioning grooves 5. At this time, the baffle 4 and the bridge frame 1 can swing relative to each other. After adjusting the inclination angle of the bottom plate 2 according to the height difference, the pins 62 can be re-inserted to finalize the shape. The bridge frames 1 on both sides are still parallel to each other, and the cables passing through them can pass smoothly.

[0030] In addition, when the cables need to be shielded, the first cover plate 7 and the second cover plate 9 can be installed by snapping the hook 8 with the flange 11, which makes the use more flexible.

[0031] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the embodiments of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
