Description

Technical Field

[0001] The utility model belongs to the technical field of bridges, and in particular relates to a height-adjustable bridge for nuclear power. Background Art

[0002] Nuclear power cable installation typically requires the use of cable trays. Cable trays come in trough, tray, ladder, and grid configurations, and are composed of brackets, supports, and mounting accessories. Cable trays can be installed independently within buildings or attached to various structures and pipe gallery supports. They should feature simple structure, attractive design, flexible configuration, and easy maintenance. All components must be galvanized and installed outdoors.

[0003] Existing general nuclear power bridges are usually fixed, and the height of the nuclear power bridge cannot be adjusted, which reduces the flexibility of the nuclear power bridge, is not conducive to adjusting the use according to actual use needs and the number of cables, and narrows the scope of application of the device. The height of some bridges can be adjusted, but it is more troublesome to adjust. The height adjustment of both sides must be divided into multiple separate adjustments and cannot be adjusted into place at one time. Therefore, a nuclear power bridge with adjustable height is proposed. Summary of the Invention

[0004] The utility model provides a nuclear power bridge with adjustable height, which aims to solve the problem that the use height of the nuclear power bridge cannot be adjusted, which reduces the flexibility of the nuclear power bridge, is not conducive to adjustment according to actual use needs and the number of cables, and narrows the application range of the device. The height of some bridges can be adjusted, but it is more troublesome to adjust. The height adjustment of both sides must be divided into multiple separate adjustments and cannot be adjusted into place at one time.

[0005] An embodiment of the present utility model provides a height-adjustable bridge for nuclear power, comprising a bridge body, side cavities being opened on both sides of the bridge body, lifting plates being slidably connected to the two side cavities, tops of the two lifting plates being fixedly connected to top plates, bottoms of the top plates being fixedly connected to symmetrically distributed rails, lifting components being slidably connected to the rails, a limiting component being provided on the lifting components, and lifting openings communicating with the side cavities being opened on the left and right sides of the bridge body.

[0006] Furthermore, the lifting assembly includes a pair of moving blocks, and the pair of moving blocks are symmetrically slidably installed on a pair of rails, and the two moving blocks are fixedly connected to a rack on one side close to each other, and a square hole is opened on the two moving blocks, and a fixed rod is fixedly connected to the middle of the pair of rails, and a gear is rotatably connected to the middle of the fixed rod. Connecting rods are installed on the front and back sides of the two moving blocks, and the two connecting rods located on one moving block are symmetrically distributed. One end of the swing rod is rotatably connected to each of the four connecting rods, and the other end of the two swing rods located on one side is rotatably connected to a rotating rod, and the rotating rod is fixedly connected to the outer side of the lifting plate.

[0007] By adopting the above technical solution, the moving block on the left can be pulled, and the movement of the moving block on the left drives the rack on it to move, and the movement of the rack drives the gear to rotate, and then drives the rack on the right moving block to move, so that the two moving blocks can move synchronously, and then drive the connecting rod to move, and let the swing rod swing. When the moving blocks approach each other, the swing rod swings gradually toward the vertical state, which can drive the rotating rod to rise, and then drive the lifting plate to rise, thereby driving the top plate to rise and adjust the height, so that both sides can rise at the same time, ensuring that there will be no height difference in the rise of the top plate, ensuring that the height adjustment is accurate and stable, and both sides can be raised at one time, which is more efficient and does not need to be adjusted separately.

[0008] Furthermore, a track groove is provided on the moving block, and the track groove matches the track.

[0009] By adopting the above technical solution, the track groove can be used to connect the moving block and the track for stable sliding.

[0010] Furthermore, the two racks are distributed up and down, and the square holes opened on the moving block are also distributed up and down and correspond to the positions of the corresponding racks.

[0011] By adopting the above technical solution, the upper and lower distributions of the racks can be staggered and will not affect or touch each other. The square hole provides space for the movement of the racks and will not allow the racks to interfere with the movement of the moving block.

[0012] Furthermore, the gear is engaged with the rack.

[0014] Furthermore, the limit assembly is installed on the moving block located on the left side, and the limit assembly includes a pair of movable cavities opened in the moving block, and the movable cavities are slidably connected with plug rods, and the protruding ends of the two plug rods are fixedly connected with pull bars, and an abutment piece is installed on the outer side of the plug rod, and a spring sleeved on the plug rod is installed above the abutment piece, and a number of evenly distributed sockets matching the plug rods are opened on the track.

[0015] By adopting the above technical solution, the limit assembly can be used to limit the moving block on the left. After adjusting the height, the movement of the moving block is limited to ensure that the top plate will not move easily after adjustment. By pulling the pull bar, the two plug-in rods are driven to move, and the plug-in rods are disengaged from the sockets, so that the moving block on the left can be moved. When the moving block raises the top plate to the appropriate position, the pull bar is released. Under the action of the spring, the spring drives the plug-in rod to reset and insert it into the corresponding socket, thereby limiting the moving block and ensuring the stability of the top plate after the height of the top plate is adjusted.

[0016] Furthermore, one end of the plug rod close to the socket can be inserted into the socket, one end of the spring is fixedly connected to the abutment piece, and the other end of the spring is connected to the cavity wall of the active cavity.

[0017] By adopting the above technical solution, the end of the connecting rod close to the socket can be inserted into the socket, which can limit the movement of the moving block. The spring can be used to apply external force to the rack to ensure that the connecting rod will not be easily separated from the socket.

[0018] The beneficial effects of the utility model are:

[0019] 1. The utility model can drive the top plate to rise and adjust the height through the lifting component, so that both sides can rise at the same time, ensuring that there will be no height difference when the top plate rises, ensuring the accuracy and stability of the height adjustment, and both sides can be raised at one time, which is more efficient and does not require separate adjustment.

[0020] 2. The utility model can limit the movable block on the left side through the limit assembly. After adjusting the height, the movement of the movable block is limited to ensure that the top plate will not move easily after adjustment. This makes the operation easier and ensures that the height of the bridge will not change easily after adjustment. The height adjustment can be used more flexibly, with more space and improved flexibility of use.

[0028] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Reference Figure 1-4 The embodiment of the utility model proposes a height-adjustable nuclear power bridge, including a bridge body 1, side cavities 2 are opened on both sides of the bridge body 1, and lifting plates 3 are slidably connected in the two side cavities 2. The tops of the two lifting plates 3 are fixedly connected with top plates 4, and the bottoms of the top plates 4 are fixedly connected with symmetrically distributed rails 6. A lifting component is slidably connected to the rails 6, and a limiting component is provided on the lifting component. Lifting ports 9 connected to the side cavities 2 are opened on the left and right sides of the bridge body 1.

[0030] The lifting assembly includes a pair of moving blocks 71, which are symmetrically slidably mounted on a pair of rails 6. The two moving blocks 71 are fixedly connected to a rack 72 on one side close to each other. Square holes 73 are provided on the two moving blocks 71. A fixed rod 74 is fixedly connected to the middle of the pair of rails 6. A gear 75 is rotatably connected to the middle of the fixed rod 74. Connecting rods 76 are installed on the front and rear sides of the two moving blocks 71. The two connecting rods 76 on one moving block 71 are symmetrically distributed. One end of the swing rod 77 is rotatably connected to the four connecting rods 76. The other ends of the two swing rods 77 on one side are rotatably connected to the rotating rod 710. The rotating rod 710 is fixedly connected to the outer side of the lifting plate 3 and can be moved by pulling the left side. The gear 75 is rotated by the gear 72, and the rack 72 is rotated, thereby driving the rack 72 on the right side of the moving block 71 to move. In this way, the two moving blocks 71 can move synchronously, thereby driving the connecting rod 76 to move, and letting the swing rod 77 swing. When the moving blocks 71 approach each other, the swing rod 77 swings gradually toward the vertical state, which can drive the rotating rod 710 to rise, and then drive the lifting plate 3 to rise, thereby driving the top plate 4 to rise and adjust the height. In this way, both sides can be raised at the same time to ensure that there is no height difference in the rise of the top plate 4, ensuring that the height adjustment is accurate and stable, and both sides can be raised at one time, which is more efficient and does not need to be adjusted separately.

[0031] A track groove 78 is provided on the moving block 71 , and the track groove 78 matches the track 6 . The track groove 78 allows the moving block 71 to be connected to the track 6 for stable sliding.

[0032] The two racks 72 are distributed up and down, and the square holes 73 opened on the moving block 71 are also distributed up and down, and correspond to the positions of the corresponding racks 72. The racks 72 can be staggered up and down without affecting each other. The square holes 73 provide space for the movement of the racks 72 and will not allow the racks 72 to interfere with the movement of the moving block 71.

[0033] The gear 75 is engaged with the rack 72 so that transmission can be performed, and the movement of one moving block 71 causes the movement of the other rack 72 through the gear 75, so that synchronous movement can be achieved.

[0034] The limit assembly is installed on the moving block 71 on the left side. The limit assembly includes a pair of movable cavities 81 opened in the moving block 71. A plug rod 82 is slidably connected in the movable cavity 81. One end of the two plug rods 82 extending out is fixedly connected to a pull bar 83. An abutment piece 84 is installed on the outside of the plug rod 82. A spring 85 sleeved on the plug rod 82 is installed above the abutment piece 84. A number of evenly distributed sockets 86 matching the plug rod 82 are opened on the track 6. The limit assembly can be used to limit the moving block 71 on the left side. When adjusting the height Afterwards, the movement of the movable block 71 is restricted to ensure that the top plate 4 will not move easily after adjustment. By pulling the pull bar 83, the two plug-in rods 82 are driven to move, and the plug-in rods 82 are disengaged from the sockets 86. This allows the movable block 71 on the left to move. When the movable block 71 raises the top plate 4 to a suitable position, the pull bar 83 is released. Under the action of the spring 85, the spring 85 drives the plug-in rod 82 to reset and insert it into the corresponding socket 86, restricting the movable block 71, and then ensuring that the top plate 4 is stable after the adjusted height of the top plate 4.

[0035] The end of the connecting rod 82 close to the socket 86 can be inserted into the socket 86, one end of the spring 85 is fixedly connected to the abutment piece 84, and the other end of the spring 85 is connected to the cavity wall of the movable cavity 81. The end of the connecting rod 82 close to the socket 86 can be inserted into the socket 86, which can limit the movement of the moving block 71. The spring 85 can be used to apply external force to the rack 72 to ensure that the connecting rod 82 will not be easily separated from the socket 86.

[0036] The specific implementation method is as follows: when in use, by pulling the pull bar 83, the two plug rods 82 are driven to move, so that the plug rod 82 is disengaged from the socket 86, so that the moving block 71 on the left can move, and then the moving block 71 on the left is pushed. At this time, the moving block 71 on the left moves and drives the rack 72 on it to move, and the rack 72 moves to drive the gear 75 to rotate, thereby driving the rack 72 on the right moving block 71 to move, so that the two moving blocks 71 can move synchronously, thereby driving the connecting rod 76 to move, so that the swing The rod 77 swings, and when the moving blocks 71 approach each other, the swing rod 77 swings gradually toward the vertical state, which can drive the rotating rod 710 to rise, and then drive the lifting plate 3 to rise, thereby driving the top plate 4 to rise and adjust the height. When the moving block 71 allows the top plate 4 to rise to a suitable position, the pull bar 83 is released. Under the action of the spring 85, the spring 85 drives the plug-in rod 82 to reset and insert it into the corresponding socket 86, thereby limiting the moving block 71, and then determining that the top plate 4 is stable after the adjusted height.
