[ example 1 ]

The technical scheme adopted by the utility model for solving the technical problems is as follows: the laying machine adopts the flat arrangement of a right-angle motor and a horizontal belt set, the belt set is horizontally arranged below the right-angle motor, the right-angle motor directly drives a driving wheel 3 of a driving belt set 18, and the height of the whole device is smaller than 150mm under the condition that the output tension is not smaller than 400N; the laying machine is hung on the C-shaped hanging rail 25 through hanging wheels 28, and the C-shaped hanging rail 25 is fixed on the upper-layer bridge frame 24 through hanging rail quick supports 22 and 23 (as shown in figure 1), so that the laying machine can horizontally move and be positioned in the direction vertical to the axis of the bridge frame, and the requirements of different arrangement positions during cable laying are met.

[ example 2 ]

In the above device, the "right-angle motor" is composed of the driving motor 1 and the reduction gearbox 2, the "horizontal belt group" is composed of the "driving belt group 18" and the "driven belt group 19", the left push rod motor 11 and the right push rod motor 12 on the left side and the right side are controlled to drive the driven belt 8 to approach and extrude the driving belt 7, so that the cable 17 to be laid clamped in the two belts moves horizontally towards the rotating direction of the driving belt 7 under the driving of the belt friction force, and the cable is pulled and arranged (as shown in fig. 2, fig. 3 and fig. 4).

[ example 3 ]

In the device, the driving belt group 18 is composed of a driving wheel 3, a first driven wheel 4, a driving belt 7 and the like; the driving wheel 3 is directly driven by a right-angle motor, so that the driving belt 7 is driven to rotate; the driven belt set 19 is composed of a second driven wheel 5, a third driven wheel 6 and a driven belt 8; the two belts are horizontally and parallelly arranged, and the bottoms of the two belts are flush; the arrangement minimizes the height of the whole device, has highest transmission efficiency and is convenient for separating and discharging the cable after laying.

[ example 4 ]

In the above device, after the cable is laid to the terminal, the driven belt set 19 is pushed to move in the direction away from the driving belt set 18 by controlling the left push rod motor 11 and the right push rod motor 12, and the left cable shifting device 15 and the right cable shifting device 16 are driven to move together, so that the cable 17 to be laid, which is placed on the lower support bearing column 27, is shifted out and falls into the lower layer bridge 26, and the separation of the cable from the device is completed (as shown in fig. 5).

[ example 5 ]

[ example 6 ] A method for producing a polycarbonate

In the device, the speed measuring switch 9 of the driven belt 8 is used for measuring, the left push rod motor 11 and the right push rod motor 12 are controlled by a PLC program, the driven belt group 19 and the driving belt group 18 can be automatically pushed to the optimal state according to cables 17 to be laid with different diameters, and the rotating speed of the driven belt 8 is close to that of the driving belt 7.

[ example 7 ]

When the cable 17 to be laid extruded and output by the laying machine is not guided in time and is rolled for too long, the cable 17 to be laid at the output end is twisted and protruded, even the extruded belt is protruded, and the work of the laying machine is influenced. In the device, a cable looseness margin detection device 30 is arranged at an output end, when the protrusion deformation of a cable 17 to be laid at the output end is too large, the output cable 17 to be laid is not guided to be conveyed out in time, the protrusion and twisted cable can trigger the protrusion stroke action of the looseness margin detection device 30, the output of a driving motor 1 of the laying machine is suspended, and meanwhile, an output signal is provided for a next-level laying machine to be suspended; when the cable 17 to be laid protruding from the output end is pulled and straightened, the protruding stroke of the cable looseness margin detection device 30 is recovered, and the output of the driving motor 1 of the laying machine is recovered; when the cable at the output end is stretched straight, the stretching stroke of the detection device 30 is operated, and at the moment, if the laying machine is in a pause state, the working state is entered (as shown in fig. 7, 8 and 9).

[ example 8 ]

To achieve "intelligent" operation of the laying machine, cable presence information must be confirmed. The cable conveyed by the belt extrusion has mobility and volatility, so that the common photoelectric detection switch is easy to miss detection and false detection. In the device, the left cable in-place sensor 13 and the right cable in-place sensor 14 adopt special linear photoelectric detection switches, and are set by a PLC program, the triggering of 'cable out-of-place signals' is delayed, the delay period signals trigger re-timing, and the missing detection and the false detection of the in-place signals caused by the cable fluctuation are corrected.

[ example 9 ]

Because the rotating speeds of the left push rod motor 11 and the right push rod motor 12 cannot be the same, even if slight rotating speed difference exists, if the synchronous start-stop control is adopted, the strokes of two ends can be inconsistent due to the difference after multiple running accumulation, and the unbalanced extrusion of the two belt sets is caused, so that the device is jammed. In the device, the left push rod motor 11 and the right push rod motor 12 are separately controlled, namely are simultaneously started, but after the stop conditions are met, the left push rod motor and the right push rod motor are respectively stopped, namely the speed difference is corrected in each operation.

[ example 10 ]

In the device, the laying machine can automatically start a laying program or start a laying termination program or prompt fault alarm (such as incomplete separation of cables, blockage of a driving motor 1, excessive jacking of a push rod motor, excessive unparallel running time of a single push rod motor and the like) according to working conditions through PLC program setting.

[ example 11 ]

The PLC control system also comprises a horizontal inclination and shaking detection switch, and the PLC control system and the superior laying machines form coordination control: when the output of the laying machine of the current stage is suspended and the laying machine of a higher stage is started, the cable to be laid between the two laying machines is stretched straight, and the laying machine of the current stage is pulled or shaken to incline to a certain angle, so that the horizontal inclination and shaking detection switch acts, and the working state is recovered if the laying machine of the current stage is in the suspended state under the control of a PLC program.

The above embodiments are illustrative of the present invention, and are not intended to limit the present invention, and any simple modifications of the present invention are within the scope of the present invention.
