Description

Technical Field

[0001] The utility model relates to the field of cable bridges, in particular to a cable bridge structure for power distribution construction. Background Art

[0002] Cable trays are divided into trough, tray, ladder, grid and other structures, and are composed of brackets, brackets and installation accessories. The cable trays in buildings can be erected independently or laid on various structures and pipe gallery brackets. They should have the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance. All parts need to be galvanized and installed in the open-air cable trays outside the building.

[0003] At present, when the cable bridge is being laid, the bridge body needs to be installed. Most of the existing installations are directly fixed on the wall, and the installation height is fixed. When the bridge needs to be added, it needs to be disassembled and then installed, which is cumbersome and inconvenient to adjust the height of the installed bridge. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a cable bridge structure for power distribution construction to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model proposes a cable bridge structure for power distribution construction, including a U-shaped mounting frame, both ends of which are fixedly mounted with mounting plates;

[0006] The U-shaped mounting frame is provided with a lifting mechanism inside, and the lifting mechanism includes a lifting plate, a bridge frame body, a U-shaped support plate, a screw rod and a crank. The bottom of the U-shaped mounting frame is rotatably connected to two screw rods that penetrate and extend into the U-shaped mounting frame. A crank is fixedly installed at one end of the two screw rods. The outer rings of the two screw rods are sleeved with lifting plates. The bottoms of the two lifting plates are fixedly installed with U-shaped support plates. A bridge frame body is provided inside the U-shaped support plate. The U-shaped support plate plays a role of lifting and lowering adjustment on the bridge frame body. Slide rails are provided on both sides of the bridge frame body.

[0007] In one example, limiting grooves are provided on both inner walls of the U-shaped mounting frame, the inner walls of the two limiting grooves are slidably connected to limiting blocks, and the sides of the two limiting blocks close to each other are fixedly connected to the lifting plate.

[0008] In one example, a slide plate is fixedly mounted on one side of the two lifting plates that are close to each other, and the slide plate matches the slide rail.

[0009] In one example, both inner walls of the bridge body are provided with mounting grooves, and the inner walls of the two mounting grooves are slidably connected with moving blocks.

[0010] In one example, springs are fixedly mounted on the tops of the two moving blocks, and the top ends of the two springs are fixedly connected to the mounting grooves.

[0011] In one example, a clamping plate is fixedly mounted on one side of the two moving blocks that are close to each other.

[0012] The cable bridge structure for power distribution construction proposed by the utility model can bring the following beneficial effects:

[0013] 1. This cable bridge structure for power distribution construction can drive the screw to rotate through a moving crank, and drive the lifting plate to lift, and the bridge body will be driven to lift and adjust through the U-shaped support plate. At the same time, the lifting of the lifting plate will drive the limit block to slide in the limit groove, and limit it when it is lifted and lowered to prevent it from slipping during lifting, thereby achieving a better lifting effect.

[0014] 2. This cable bridge structure for power distribution construction will squeeze the card plate when the cable is routed, which will cause the moving block to move in the installation groove and squeeze the spring. At this time, the card plate will have a current force under the action of its potential energy, and the routing cables will be better clamped and separated to prevent them from sticking together, thereby achieving a better routing effect.

[0020] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0021] like Figure 1 to Figure 3As shown, the embodiment of the utility model proposes a cable bridge structure for power distribution construction, including a U-shaped mounting frame 1, and mounting plates 15 are fixedly installed at both ends of the U-shaped mounting frame 1;

[0022] A lifting mechanism is provided inside the U-shaped mounting frame 1, and the lifting mechanism includes a lifting plate 2, a bridge frame body 5, a U-shaped support plate 6, a screw rod 7 and a crank 8. The bottom of the U-shaped mounting frame 1 is rotatably connected to two screw rods 7 that penetrate and extend into the U-shaped mounting frame 1. A crank 8 is fixedly installed at one end of the two screw rods 7. The outer rings of the two screw rods 7 are sleeved with lifting plates 2. The bottoms of the two lifting plates 2 are fixedly installed with U-shaped support plates 6. A bridge frame body 5 is provided inside the U-shaped support plate 6. The U-shaped support plate 6 plays a role of lifting and lowering adjustment on the bridge frame body 5. Slide rails 4 are provided on both sides of the bridge frame body 5.

[0023] Specifically, limiting grooves 10 are provided on the inner walls on both sides of the U-shaped mounting frame 1, and the inner walls of the two limiting grooves 10 are slidably connected to the limiting blocks 9. The two limiting blocks 9 are fixedly connected to the lifting plate 2 on one side close to each other. The limiting grooves 10 are used to slide and limit the limiting blocks 9, and the limiting blocks 9 limit the lifting and lowering of the lifting plate 2.

[0024] Specifically, a slide plate 3 is fixedly installed on one side of the two lifting plates 2 that are close to each other. The slide plate 3 matches the slide rail 4. The lifting plates 2 are auxiliary limited by matching the slide plate 3 with the slide rail 4.

[0025] Specifically, installation grooves 11 are provided on the inner walls of both sides of the bridge body 5 , and the inner walls of the two installation grooves 11 are slidably connected with moving blocks 12 . The moving blocks 12 are installed through the installation grooves 11 , and the moving blocks 12 fix the clamping plates 14 .

[0026] Specifically, springs 13 are fixedly mounted on the tops of the two moving blocks 12 , and the top ends of the two springs 13 are fixedly connected to the mounting grooves 11 , so that the moving blocks 12 are reset by the springs 13 .

[0027] Specifically, a clamping plate 14 is fixedly installed on one side of the two moving blocks 12 that are close to each other, and the cables in the bridge body 5 are clamped and secured by the clamping plate 14 to prevent them from sticking together.

[0028] Working principle: the bridge body 5 needs to be raised or lowered. At this time, rotating the crank 8 can drive the screw rod 7 to rotate, and drive the lifting plate 2 to rise or fall, which will drive the bridge body 5 to rise or fall through the U-shaped support plate 6. At the same time, the lifting of the lifting plate 2 will drive the limit block 9 to slide in the limit groove 10, and limit it when it is lifted or lowered to prevent it from slipping during lifting or lowering, thereby achieving a better lifting effect. When the cable is routed in the bridge body 5, the clamping plate 14 will be squeezed, and the moving block 12 will move in the installation groove 11, which will squeeze the spring 13 and generate potential energy. At this time, under the action of its potential energy, the routing cable will be better clamped through the clamping plate 14 to prevent them from sticking together during routing, so that they can be separated and clamped through the clamping plate 14 to achieve a better routing effect.
