Detailed Description

Following through the utility model discloses a dual drive traction winch of adaptable different diameter optical cable is the embodiment to combine the figure, it is right to make further specific explanation in technical scheme of the utility model.

As shown in fig. 1, 2, 3, 4 respectively be the embodiment of the utility model provides a double drive traction winch owner of adaptable different diameter optical cable looks at, looks left, overlooks and the back schematic diagram, it includes driving winch 1, driven capstan 2, driving synchronous pulley 3, driven synchronous pulley 4, gear motor 5, take-up pulley 6, guide pin bushing 7, winch box 8, grooving 9, drive shaft 10 and backup pad 11. The surface parts of the driving capstan 1 and the driven capstan 2 are hollowed out, and key grooves are formed in the central holes of the driving capstan 1 and the driven capstan 2 so as to be connected with a driving shaft 10; the driving synchronous pulley 3 and the driven synchronous pulley 4 are fixed on the support plate 11 through a bearing support; the upper part of the winch box body 8 and the upper part of the supporting plate 11 are both provided with two bolt holes, and the lower part of the winch box body 8 and the lower part of the supporting plate 11 are both provided with one bolt hole, so that the installation and fixation of the winch box body 8 and the supporting plate 11 are ensured by bolts and supporting sleeves; one side of the driving shaft 10 is connected and fixed on the supporting plate 11 through a bearing and a bearing support, the other side of the driving shaft 10 is connected on the winch box body 8 through an angular contact ball bearing, holes are formed in the left side and the right side of the winch box body 8, and bolt holes are formed around the end face of each hole to install the speed reduction motor 5.

The mounting height of the driven winch 2 on the winch box body is lower than that of the driving winch 1, and the height difference is the maximum diameter of the applicable optical cable; the number of rope grooves of the driving winch 1 is the same as that of the driven winch 2, and the driven winch 2 and the driving winch 1 extend out by a distance of one rope groove compared with the driven winch in the axial installation dimension.

The driving capstan 1 and the driven capstan 2 are respectively connected with the driving synchronous pulley 3 and the driven synchronous pulley 4 through a driving shaft 10, the driven synchronous pulley 4 is connected with the driving shaft 10 through an angular contact ball bearing, and the contact angle is 15 degrees. The driving winch 1 and the driven winch 2 are respectively driven by respective speed reducing motors, the speed reducing motors of the driving winch 1 are set to be in a speed servo mode by a control system, the speed reducing motors of the driven winch 2 are set to be in a torque servo mode by the control system, the output torque of the speed reducing motors in the torque control mode can be set in a grading mode according to the load torque, but the maximum set torque of the speed reducing motors is smaller than the rated torque of the speed reducing motors in the speed servo mode, and the purpose is that the driven winch 2 can always follow the driving winch 1 under the action of optical cables, and only a certain torque is generated. The dragging load is mainly borne by the driving winch 1, and is therefore called the driving winch, and the other winch mainly follows the driving winch with a certain moment, and is therefore called the driven winch. Because the gear motor of the driven winch 2 is in a torque servo mode, the phenomenon of galloping can be caused when the driven winch is started under the condition of no load, and therefore the two winches are connected through the synchronous belt and synchronously rotate, and the phenomenon of galloping of the driven winch 2 when the optical cable is not wound in a debugging state is avoided. Accordingly, the synchronous pulley 3 connected to the driving capstan 1 is referred to as a driving synchronous pulley, and the synchronous pulley 4 connected to the driven capstan 2 is referred to as a driven synchronous pulley.

The distance between the driving synchronous belt wheel 3 and the driven synchronous belt wheel 4 is constant, so that a tensioning wheel 6 is arranged to ensure the tensioning force of the belt on the synchronous belt wheels and ensure the normal operation of the belt in order to avoid the loosening and slipping phenomenon of the belt on the two synchronous belt wheels caused by certain conditions. The tension wheel 6 is mounted on a tension wheel shaft through a bearing, and one end of the tension wheel shaft is fixed on the support plate 11 through a nut. The whole tension pulley 6 is positioned right above the midpoint of the central connecting line of the two main synchronous pulleys and the driven synchronous pulley.

As shown in fig. 5 and 6, which are schematic front and left views of the rope groove 9, the rope groove 9 is made of different materials, has different static friction coefficients with the optical cable, and can be selected to have different models according to the required damping tension. Generally speaking, the static friction coefficient is gradually increased from the cable inlet end to the cable outlet end of the load, and the rope grooves of the driving capstan and the driven capstan wound by each circle of the cable are the same as the average static friction coefficient of the cable.

The driving winch 1 and the driven winch 2 are provided with a plurality of rope grooves 9, and the tension relation between the cable outlet end and the cable inlet end of each rope groove is determined by the following formula

Wherein:

F₁is the tension of the cable inlet end;

F₂is the tension of the cable outlet end;

theta is an effective friction wrap angle for winding the optical cable and the rope groove 9;

f is the coefficient of static friction between the optical cable and the rope groove 9.

As shown in fig. 7-9, the driving capstan 1 and the driven capstan 2 are both formed by connecting a single capstan through bolts, the discs of the capstan have only one groove, the driving capstan 1 and the driven capstan 2 can be embedded with rope grooves 9 with different bottom diameters, widths and open angles between adjacent discs, so as to adapt to optical cables with different diameters, and the rope grooves 9 are in a two-half circular ring structure and are fixed on the discs of the driving capstan 1 and the driven capstan 2 through bolt connection. In practical application, due to different application scenes, the driven loads are different in size, and the required tension attenuation degree is met by splicing the winch discs and the rope grooves in the corresponding number according to different requirements of different conditions.

Before the system is installed, the actual static friction coefficients of the optical cable and the rope groove 9 need to be detected through related instruments, and through tension attenuation calculation, a proper rope groove is selected to be sequentially installed in the main winch and the auxiliary winch from outside to inside according to the static friction coefficients from large to small. After the rope groove is installed, referring to fig. 1, the optical cable enters from the left side hole of the winch box body 8, passes through the guide sleeve 7 on the lower portion of the driven winch 2, is wound in the first rope groove of the driven winch 2, passes through the guide sleeve 7 on the upper portion of the driven winch 2 after about half of a circle, then enters the first rope groove of the driving winch 1 to be wound, and also sequentially passes through the guide sleeve 7 on the upper portion and the lower portion of the driving winch 1 to enter the second rope groove of the driven winch 2, so on, and finally exits from the last rope groove of the driving winch 1 and exits from the right side hole (blocked in fig. 1) of the winch box body 8.
