Description

Technical Field

[0001] The invention relates to the technical field of cable conveying equipment, in particular to a conveying device and method for cable laying. Background Art

[0002] The composition of the cable includes conductor, insulating inner sheath, outer sheath and armor, and is usually composed of several or several groups of wires. In the construction process of urban power systems, transmission cables are usually laid underground, such as in pipelines. Since the cables have a multi-layer structure and are relatively strong, the traditional method is to insert the cables into the pipeline and transport them forward by external force. However, when multiple cables are laid in the pipeline, the friction between the cables is large, making it difficult to insert the subsequent cables into the pipeline, consuming a lot of manpower and material resources, and inefficient. In addition, this laying method also causes multiple cables to cross and pile up, which is quite chaotic.

[0003] Patent document with publication number CN 114476820 A discloses a conveying device for laying power cables, comprising a conveying support device arranged at the opening of a cable duct and a traction support device arranged in the cable duct; the conveying support device comprises a support frame, a lower conveying roller is arranged in the support frame, a moving plate is arranged in the support frame, the top of the moving plate is fixedly connected to a lifting device, an upper conveying roller is arranged at the bottom of the moving plate, a first driving motor is also arranged on the moving plate, and the first driving motor is connected to the upper conveying roller shaft; the traction support device comprises a traction box, a cable clamping plate is arranged on the traction box, a support plate is arranged inside the traction box, a telescopic rod is arranged on the support plate, the telescopic rod is connected to a sliding plate, a spring is sleeved on the telescopic rod, a roller is arranged on the sliding plate, and a second driving motor is also arranged on the sliding plate; the invention can convey cables into the duct to prevent the cables from getting stuck in the duct, reduce labor intensity, and improve cable laying efficiency. However, when laying cables, they can only be transported in the center of the pipeline. After transportation, the cables fall freely and accumulate. After laying multiple cables, there is a state where the middle is high and the two sides are low, which affects the subsequent cable transportation. Moreover, after the cables fall freely, multiple cables are still cross-piled and arranged in a chaotic manner. Summary of the invention

In addition, the position adjustment component also has a telescopic rod for adjusting the vertical position of the cable driving component. When cables are conveyed to cable pipes of different sizes, the cable driving component can be located at the height of the horizontal center line of the pipe by adjusting the telescopic rod, thereby facilitating the smooth laying of the cable.

[0017] 4. In the conveying device for laying cables of the present invention, two U-shaped frames of the cable driving component are plugged at both ends and elastically fixed by springs and locking bolts, so that the cable can be tightly clamped between the two driving rollers with an elastic margin, and the cable can be protected while being driven for transportation; the supporting component in the cable conveying mechanism adopts two stretching rods to adjust the horizontal position of the cable, and the two stretching rods are on the same horizontal line with the horizontal center line of the pipeline, so when the cable is conveyed, the rollers at the outer ends of the two stretching rods can be in close contact with the inner walls on both sides of the pipeline and roll along the horizontal axis of the pipeline, and since the cable itself has a large weight and strength, the cable and the supporting component can be conveyed along a predetermined position by driving the two driving rollers.

[0024] like Figure 5As shown, the conveying device and the conveying method for cable laying of the embodiment of the present invention, when conveying cables through the cable pipeline, since the pipeline cross-section is circular, when the first cable is laid, the circular frame of the cable conveying mechanism can be adjusted to the center of the pipeline. After the conveying is completed, the cable falls on the bottom of the pipeline. Then, when laying the second and third cables, the circular frame is adjusted to the left and right sides of the center of the pipeline in batches, and then falls on the left and right sides of the first cable respectively until the first layer of the pipeline is filled, and then the second and third layers are arranged in the same way... until they cannot be arranged (generally, the cables in the pipeline do not reach the center line position). The cables laid by the conveying device and the conveying method of the present invention are arranged neatly, without cross-piling, and the arrangement efficiency is high. Example

[0025] like Figure 6 As shown, the cable laying conveying device of the embodiment of the present invention is further improved on the basis of the embodiment 1, and the difference between the embodiment 1 and the embodiment 1 is that: In the cable conveying mechanism, a double roller design is adopted at the end of the stretching rod, that is, it includes two rollers 19, and the two rollers 19 are respectively hinged to the connecting plate 21 at the end of the stretching rod through a bending rod 20.

[0026] In the embodiment of the present invention, the two ends of the circular frame are supported by the inner wall of the pipe through four rollers arranged in a "spider leg" shape. Not only can the cable conveying mechanism be kept moving in a straight line when the circular frame is not in the center of the pipe and the center of gravity is unstable, but also, when the pipe wall is uneven, the second spring has a buffering effect and there will be no problem of conveying jams and stagnation, thereby greatly improving the stability of the cable conveying mechanism during the conveying process.
