Technical Field

The invention relates to the field of cable laying, in particular to an underwater wiring device.

Background

At present, most of cable laying is performed from the underground, and generally, pipelines are laid firstly and then are laid from the pipelines. Even in waters such as rivers, the pipeline is usually buried by digging pits on the water bottom. Because the pipeline is formed by connecting a straight pipe, a well is arranged at a certain distance, particularly at a corner, and the well is not provided with the pipeline. So several workers are needed to assist in the run of the cable in the well when laying the cable.

At present, cable laying is mainly carried out by pulling a motor at a terminal end, and workers assist in wire feeding. Two main work of assisting in conveying the cable by workers in the well are provided, and firstly, when the cable head comes, the cable head is ensured to be accurately inserted into the next pipeline; secondly, when the cable is normally wired, the cable is prevented from being clamped. The cable is blocked in the well mainly at the turning position, and because the angle is changed, the cable does not straightly enter the pipeline, so the cable is easily blocked by the pipeline port, and even the cable skin is scratched. In this case, workers have no good method and can only adjust the angle of the cable in the well by using a steel pipe or a crowbar.

Moreover, the pipeline is buried in the water area, and a problem that mud is easily adhered to the cable during the wiring is also easy to occur. This mud enters the pipe and, if it builds up, can interfere with subsequent routing. And the mud in the pipe is extremely difficult to clean, so it is necessary to ensure that the cable is clean when entering the pipe.

The specific implementation mode and principle are as follows:

when the device is used, the inserting towing ring 02 is inserted into the pipeline 1, the pushing towing ring 01 is pushed against a cement wall of an opening of the pipeline in the well, then the fixed hand wheel 06 is screwed, the driving gear 104 is meshed with the transmission gear 103, the transmission gear 103 is meshed with the bevel gear 102, the bevel gear 102 is sleeved outside the threaded telescopic rod 101 and is in threaded connection with the threaded telescopic rod, finally the threaded telescopic rod 101 is driven to extend out, a pushing piece 107 at the outer end of the threaded telescopic rod 101 is pushed against the inner wall of the pipeline 1 at the other side, and the stability of the device is ensured;

then the folding steel ring 08 is rotated to form a closed loop with the opening steel ring 07, the closed loop is locked through the buckle 010 and kept fixed, and then the air bag 09 is inflated until the air bag 09 completely wraps the cable without a gap. When the cable is wired, the air bag 09 can automatically wipe off mud on the cable.

When the cable is laid, the cable is pressed against the supporting wheel 03, and the supporting wheel 03 rotates like a pulley to assist in the laying. When the cable is clamped, the force between the cable and the supporting wheel 03 is increased, so that the supporting wheel 03 sinks inwards, the angle is adjusted, and the cable is promoted to be laid. If the cable is still clamped, as long as the motor at the terminal end is not stopped, the force between the cable and the resisting wheel 03 is continuously increased, and finally the expansion bracket 04 presses the pressing rod 204 to move downwards, so that the first piston 205 moves downwards to change the air pressure in the closed cavity 208, so that the second piston 206 in the rack movable cavity 209 moves outwards, and the rack 207 is driven to move to drive the driving gear 305 to rotate;

the driving gear 305 rotates to drive the threaded push rod 304 in the driving gear to ascend, the threaded push rod 304 ascends to enable the piston III 303 to move upwards, lubricating oil in the oil cavity 302 is extruded out at the corresponding position, the connecting position is lubricated, and cables can conveniently and smoothly pass through the connecting position.

After the force between the cable and the resisting wheel 03 is reduced, the buffer spring 203 enables the expansion bracket 04 and the resisting wheel 03 to ascend, the pressing rod 204 is loosened, the pressing rod 204 resets under the action of a reset spring (not shown in the figure), so that the first piston 205 resets, the second piston 206 in the rack movable cavity 209 resets through air pressure change, the driving rack 207 moves back, but the one-way bearing 306 is arranged in the driving gear 305, so that the driving rack 207 only moves back to enable the driving gear 305 and the one-way bearing 306 to rotate relatively, and the threaded push rod 304 cannot be driven to descend.

Based on the above, the invention inserts the towing ring into the pipeline, the propping towing ring props against the cement wall of the pipeline opening in the well, and the propping piece props against the inner wall of the pipeline, so as to ensure the stability of the equipment; the inner wall of the pushing and dragging ring is provided with a pushing wheel which plays a role of a pulley.
