Description

Technical Field

[0001] The utility model relates to a splicing type bridge frame, belonging to the field of cable support equipment. Background Art

[0002] The splicing type bridge frame is a widely used cable support system, usually used in buildings and industrial facilities to effectively manage the layout of cables and pipelines.

[0003] In the prior art, the splicing type bridge frame is mainly composed of a top plate, a bottom plate and two side plates which are spliced by clamping. The inside of the spliced bridge frame is used to load and arrange cables, and the cables need to be supported by weight. However, only a clamping groove for clamping with the bottom plate is arranged at the bottom of the relative side of the two side plates. When the bottom plate bears the gravity of the cables for a long time, it is easy to cause deformation at the clamping joints on both sides of the bottom plate of the bridge frame, resulting in insecure clamping between the side plates and the bottom plate, and reducing the load-bearing stability of the splicing type cable bridge frame.

[0004] In summary, the utility model provides a splicing type bridge frame to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a splicing type bridge frame to solve the problem of poor overall load-bearing stability of the bridge frame caused by insecure splicing in the above background art.

[0006] To achieve the above purpose, the utility model is realized by the following technical solutions: a splicing type bridge frame includes an upper frame. Convex strips are fixedly connected to both sides of the inner wall and both sides of the outer wall of the upper frame. Clamping grooves are formed on the separated sides of every two adjacent convex strips. A first clamping seat is clamped in the upper frame through the clamping grooves on the relative sides of the two convex strips. A lower frame is fixedly connected between the relative sides of the two first clamping seats and inside the upper frame. A second clamping seat is clamped through the clamping grooves on the separated sides of the other two convex strips. A reinforcing frame is fixedly connected between the separated sides of the two second clamping seats and below the upper frame. A plurality of long rod screws penetrate through the two sides of the reinforcing frame from front to back evenly. One end of each long rod screw penetrates through the second clamping seat and the upper frame in sequence and extends into the inside of the first clamping seat.

[0007] Furthermore, the long rod screw is in threaded connection with the second clamping seat, and the long rod screw is in threaded connection with the first clamping seat.

[0008] Furthermore, the upper frame is in threaded connection with the long rod screw, and the reinforcing frame is in threaded connection with the long rod screw.

[0009] Furthermore, threaded holes for cooperating with the threaded connection of the long rod screw are formed between the inside of the reinforcing frame, the second clamping seat, the upper frame and the first clamping seat.

[0010] Furthermore, the bottom, front and back of the upper frame are all open, the top, front and back of the lower frame are all open, and the top of the lower frame is in contact with the top of the inner wall of the upper frame.

[0011] Furthermore, the top, front and back of the reinforcement frame are all open, and the bottom of the inner wall of the reinforcement frame is in contact with the bottom of the upper frame.

[0012] Furthermore, the bottom of the lower frame contacts the bottom of the inner wall of the reinforcement frame, and a plurality of heat dissipation windows are evenly arranged from front to back between the bottom of the inner wall of the lower frame and the bottom of the reinforcement frame.

[0013] Beneficial effects of the utility model:

[0014] The convex strips and the card grooves on both sides of the inner wall of the upper frame are respectively connected with the two first card seats to bear the weight of the lower frame. At the same time, the second card seats on both sides of the inner wall of the reinforcement frame will be connected with the convex strips on both sides of the outer wall of the upper frame to prevent the bottom opening of the upper frame from being stretched open due to the gravity of the lower frame and the cable. At the same time, the bottom of the lower frame is assisted to bear the weight, which prevents the bridge splicing bottom plate and frame from falling and deforming due to the gravity of the loaded cables, thereby effectively improving the load-bearing stability of the spliced ​​cable bridge.

[0015] When the upper frame, lower frame and reinforcement frame are spliced ​​together, the threaded holes on the upper frame, lower frame and reinforcement frame are aligned with each other, and then the long rod screws are aligned with the threaded holes and rotated and screwed in, so that the upper frame, lower frame and reinforcement frame can be fixed to avoid the offset of the splicing structure between the upper frame, lower frame and reinforcement frame when the bridge is installed at an angle, effectively improving the firmness of the splicing installation of the cable bridge.

[0016] The heat dissipation window can be used to ventilate and dissipate heat for the cables placed between the upper frame and the lower frame, thereby improving the safety of cable power-on work. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a spliced bridge frame, including an upper frame 1. On both sides of the inner wall and both sides of the outer wall of the upper frame 1, ribs 2 are fixedly connected. On one side of each two adjacent ribs 2 away from each other, a card slot 3 is opened. The main cross-section of the card slot 3 is in a "T" shape, and the main cross-section of the rib 2 is in a "T" shape. On the relative side of the two ribs 2 and inside the upper frame 1, a first card holder 4 is clamped through the card slot 3. Between the relative sides of the two first card holders 4 and inside the upper frame 1, a lower frame 6 is fixedly connected. On the side of the other two ribs 2 away from each other, a second card holder 5 is clamped through the card slot 3. Between the sides of the two second card holders 5 away from each other and below the upper frame 1, a reinforcement frame 7 is fixedly connected. On both sides of the reinforcement frame 7, a plurality of long rod screws 9 are evenly penetrated from front to back. One end of each long rod screw 9 sequentially penetrates through the second card holder 5 and the upper frame 1 and extends into the first card holder 4. The long rod screw 9 is threadedly connected to the second card holder 5, the long rod screw 9 is threadedly connected to the first card holder 4, the upper frame 1 is threadedly connected to the long rod screw 9, and the reinforcement frame 7 is threadedly connected to the long rod screw 9. Threaded holes 8 for mating with the threaded connection of the long rod screw 9 are opened between the inner parts of the reinforcement frame 7, the second card holder 5, the upper frame 1 and the first card holder 4. The reinforcement frame 7, the second card holder 5, the upper frame 1 and the first card holder 4 are fixedly connected through the long rod screw 9. The two sides of the lower frame 6 are respectively in contact with the relative sides of the two ribs 2. The two sides of the inner wall of the reinforcement frame 7 are respectively in contact with the sides of the other two ribs 2 away from each other.

[0025] Please refer to Figures 2-4 , the bottom, front and back of the upper frame 1 are all open. The top, front and back of the lower frame 6 are all open. The top of the lower frame 6 is in contact with the top of the inner wall of the upper frame 1. The top, front and back of the reinforcement frame 7 are all open. The bottom of the inner wall of the reinforcement frame 7 is in contact with the bottom of the upper frame 1.

[0026] Please refer to Figures 2-3, the bottom of the lower frame 6 is in contact with the bottom of the inner wall of the reinforcement frame 7. A plurality of heat dissipation windows 10 are evenly arranged from front to back between the bottom of the inner wall of the lower frame 6 and the bottom of the reinforcement frame 7. Through the heat dissipation windows 10, ventilation and heat dissipation can be carried out on the cables installed between the upper frame 1 and the lower frame 6.

[0027] Specific implementation method: Align the first card seats 4 fixedly connected to both sides of the lower frame 6 with the card slots 3 on the two convex strips 2 inside the upper frame 1, and push the first card seats 4 into the inside of the convex strips 2 from the front end of the card slots 3, so that the lower frame 6 can be quickly fixed between the two sides of the inner wall of the upper frame 1. Then align the second card seats 5 on both sides of the inner wall of the reinforcement frame 7 with the fronts of the card slots 3 on the convex strips 2 on both sides of the outer wall of the upper frame 1, and push the two second card seats 5 into the inside of the other two convex strips 2 from the front ends of the card slots 3 on the other two convex strips 2. When the upper frame 1, the lower frame 6 and the reinforcement frame 7 are spliced, the top of the inner wall of the upper frame 1 fits with the top of the lower frame 6, and the bottom of the inner wall of the reinforcement frame 7 fits with the bottom of the lower frame 6. When the lower frame 6 bears the gravity of the cables inside, the convex strips 2 on both sides of the inner wall of the upper frame 1 will be respectively clamped with the two first card seats 4 through the card slots 3 to bear the weight of the lower frame 6. At the same time, the second card seats 5 on both sides of the inner wall of the reinforcement frame 7 will be clamped with the convex strips 2 on both sides of the outer wall of the upper frame 1, preventing the bottom opening of the upper frame 1 from being spread open due to the gravity of the lower frame 6 and the cables, and at the same time assisting in bearing the weight of the bottom of the lower frame 6, avoiding the situation that the splicing bottom plate and frame of the cable bridge sag and deform due to the gravity of the loaded cables, thereby effectively improving the load-bearing stability of the spliced cable bridge.

[0028] After the upper frame 1, the lower frame 6 and the reinforcement frame 7 are spliced, the threaded holes 8 on the upper frame 1, the lower frame 6 and the reinforcement frame 7 are aligned with each other, and then the long rod screws 9 are aligned with the threaded holes 8 and rotated and screwed in, so as to fix the upper frame 1, the lower frame 6 and the reinforcement frame 7, preventing the splicing structure between the upper frame 1, the lower frame 6 and the reinforcement frame 7 from shifting when the cable bridge is installed obliquely, and effectively improving the firmness of the splicing installation of the cable bridge.

[0029] Through the heat dissipation windows 10, ventilation and heat dissipation can be carried out on the cables placed between the upper frame 1 and the lower frame 6, improving the safety of the cables during power-on operation.
