Description

[Detailed Description of the Invention] The present invention relates to a lashing machine that binds overhead cables and suspension lines with wire.

When spanning cables, from the viewpoint of strength,
It is necessary to reduce the stranding force applied to the cable by extending the suspension wire between utility poles and wrapping the cable around the suspension wire with lashing wire. Conventionally, lashing wires have been wound using a lashing machine having the configuration shown in the side view of FIG.

A conventional lashing machine has a coil case 3 containing a lashing wire, a tension roller 4, a friction roller 5, and a wire ring 7 on both sides of an outer tube of a rotor section made of a double tube. Further, a friction plate 6 and a cable guide roller are attached to one end of the inner tube of the rotor section 2, and a suspension wire guide roller, a cable guide roller, a handle pusher, and an eyebold are attached to the inner tube of the rotor section at the other end. .

The operating principle of the lashing machine is as follows. The lower ends of the stator section 1, rotor section 2, and handle 17 of the lashing machine are opened and attached to the cable 19 and suspension wire 20. 2 coil cases 3
The lashing wires 21 taken out from the cable are wound around the tension roller 4 and the friction roller 5, and then passed through the wiring 7 and fixed to one end e of the cable. Next, when the lashing machine is pulled in the X direction, the lashing wire 21 is paid out, and the tension roller 4
The friction roller 5 and the friction rubber roller integrated with the friction roller rotate. When the release lever 13 brings the friction rubber roller into contact with the friction plate 6 of the stator section 1, the rotor section 2 rotates. As a result, the coil case 3 attached to the rotor section 2 rotates, and the lashing wire 21 fed out from the coil case is wound spirally around the cable 19 and the suspension wire 20, as shown in FIG. Can be attached.

The lashing wire 21 wound in this manner may be broken due to mechanical external force or corrosion caused by backups used in road construction or loading of dump trucks. At this time, the lashing wire must be restrung, but conventional lashing machines only had the function of spirally winding the lashing wire around the cable and suspension wire as described above, so Re-stretching the single wire was accomplished by separately removing the old wire and winding the new wire.

That is, the lashing wire was re-strung by the following process.

(1) As shown in Figure 3a, move the lead wheel 22 installed on the cable 19 and suspension line 20 in one direction, and use the wire collecting rod 23 inserted between the suspension line and the cable to secure the wire. The sing wire is collected in front of the leading metal wheel without being unwound, and then cut and removed at the terminal end of the utility pole 24 or the like. At this time, when the lashing wire is removed, the stranding force is applied directly to the cable, so several movable latching wheels 26 connected to the leading latching wheel with connecting ropes 25 are used.
to hold the cable on the suspension line.

(2) To wind the new wire, as shown in Fig. 3b, the lashing machine 27 installed on the cable 19 and the suspension wire 20 is towed, the movable metal wheel 26 is pushed in one direction, and the above-mentioned operation is carried out. The latching wire is wrapped around the cable and suspension wire according to the principle. The terminal end of the lashing wire was fixed with a grip.

Therefore, the lashing wire must be replaced in multiple steps, which poses a problem in workability.

In order to eliminate these drawbacks, the present invention attaches a latching wire removal device to a conventional lashing machine so that the old wire can be removed and the new wire wrapped at the same time in a single towing operation. The drawings will be described in detail below.

This invention adds a bevel gear to the conventional latching machine.
This is equipped with a lashing wire removal device consisting of spur gears, internal gears, etc. FIG. 4 is a side view of an embodiment of the present invention, and FIG. 5 is a schematic diagram of a lashing wire removing device, in which a is a plan view and b is a front view.
Note that in FIG. 5, the eyebold 16, pusher 15, rotor section 2, coil case 3, etc. are omitted. Specifically, a first bevel gear 28 is attached to the shaft of the suspension line guide roller 12 of a conventional lashing machine, and a second bevel gear 29 is meshed with the bevel gear 28. Next, the second bevel gear 29 is connected to the spur gear 3.
0 is attached, and the internal gear 31 is further meshed with the spur gear 30. The internal gear 31 has a plurality of mounting legs 32 attached to the side surface of the handle, and a disc 34 for preventing lashing wires from being caught in the wire, which has a plurality of wire unwinding pins 33 attached to the opposite surface thereof. ing. Incidentally, a notch 35 is formed in the internal gear 31 and the disc 34 for preventing the lashing wire from getting caught so that the lower part can be opened and closed when the lashing machine is installed on the cable and suspension line.

The operation of the lashing machine of the present invention is as follows.

After the lashing machine is installed on the cable and suspension wire, one end of the lashing wire to be removed is hooked to the wire unwinding pin 33. When the lashing machine is towed in the X direction by a towing rope connected to the eye bolt 16 (see FIG. 4), the suspension line guide roller 12 rotates in the vertical direction. This longitudinal rotation is converted into lateral rotation of the internal gear by two bevel gears and one spur gear. That is, when the suspension wire guide roller 12 rotates in the vertical direction, the two bevel gears 28 and 29 cause the spur gear 30 to rotate in the horizontal direction counterclockwise with respect to the X direction. As a result, the internal gear 31 meshing with the spur gear 30 rotates laterally in the counterclockwise direction in the same direction as the spur gear. Therefore, the wire unwinding pin 33 attached to the internal gear 31 is rotated laterally counterclockwise with respect to the X direction, and the lashing wire is unwound. Even when the lashing wire is cut in the middle, one end of the cut wire is caught on the wire unwinding pin 33 of the moving lashing machine and is unwound. It should be noted that if one end of the lashing wire to be unwound is not hooked to the wire unwinding pin, but is simply kept in contact with the lashing wire entrainment prevention disc 34, the lashing wire and the wire entrainment prevention disc 34 can be easily removed. The latching wire is unwound by the frictional force between the latching wire and the latching wire.

The lashing machine of the present invention is a conventional device with a lashing wire removal device attached, and has the function of removing the lashing wire as well as the function of wrapping the conventional lashing wire, so the old wire can be removed. Immediately after unwinding, wrap the cable and suspension wire with new wire.

The winding method is the same as before and is as follows.
The lashing wires 21 taken out from the two coil cases 3 are wound around the tension roller 4 and the friction roller 5, and then fixed to one end of the cable. Next, when the lashing machine is towed in the X direction, the lashing wire 21 is paid out, and the frictional force with the wire causes the tension roller 4 and the friction roller 5 to be moved to the friction rubber roller 22, which is integrated with the friction roller. rotates. When the friction rubber roller 22 is brought into contact with the friction plate 6 of the stator section 1 by the release lever 13, the rotor section 2 rotates. As a result, the coil case 3 attached to the rotor section 2 rotates, and the lashing wire 21 drawn out from the coil case is wound helically around the cable 19 and the suspension wire 20. Note that the new wire is wound counterclockwise with respect to the traction direction X.

The unwound lashing wire is cut off at the terminal end and removed. As can be seen from the above, the driving force for winding in the lashing machine of the present invention is the rotational force of the friction roller due to traction, and the driving force for unwinding is the rotational force of the sling guide roller due to traction.

In this example, two bevel gears and one spur gear are used to convert the vertical rotation of the suspension guide roller into horizontal rotation of the internal gear, but the number of gears can be reduced by combining other gears. It is also possible to convert using gears.

When simply winding the lashing wire without unwinding it, the bevel gear and the mounting leg are connected to the suspension wire guide roller 12 and the handle 1, respectively.
It can be removed and used from 7.

As explained above, the latching machine of the present invention has a latching wire removal device consisting of bevel gears, spur gears, internal gears, etc. attached to the conventional device, so it can remove the old wire and replace the new wire with one towing. Winding can be done simultaneously. Therefore, the lashing wire re-stretching using the lashing machine of the present invention has the advantage that the number of steps can be reduced compared to the conventional method, and workability can be greatly improved.
