Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention mainly relates to a self-propelled machine that pulls a lashing machine along a messenger wire.

(Prior art) A conventional lashing machine, as shown in Fig. 5,
The lashing machine 52 attached to the messenger wire 51 and the leading vehicle 53 provided in front of the lashing machine 52 are connected by a traction plate 54, and the self-propelled machine 55 also suspended from the messenger wire 51 and the above-mentioned traction A rope 56 is connected to the plate 54, and the self-propelled machine 55 is operated to connect the messenger wire 51.
The latching machine 52 is pulled by running on top of the latching machine. As a result, the self-propelled machine 55 pushes the movable metal wheel 58 in front of the self-propelled machine 55 on which the multi-stranded cable 57 is mounted, and the cable 57 is transferred from the movable metal wheel 58 to the self-propelled machine 58.
5, guided by a leading vehicle 53, and introduced into the latching machine 52. At the rear of the latching machine 52, the messenger wire 51 and the multi-strand cable 57 are bundled, and a lattice is attached to their outer periphery. A sing wire (not shown) is wound spirally.

(Problem to be solved by the invention) When using the above self-propelled machine 55, the cable 5
7 passes under this self-propelled aircraft 55 and is guided by the guide vehicle 3, so there is a risk of it deflecting significantly downward, and there are places where utility poles are congested, such as where there are multiple lines such as communication lines directly below. This is not desirable as it may come into contact with these lines and cause damage. Therefore, a conventional self-propelled machine cannot be used for lashing work in such a narrow tap area with the railway line below.

Therefore, it is possible to integrate a self-propelled machine into the latching machine to prevent the cable from sagging, but if you try to lash multiple cables at the same time, a maximum traction force of about 50 kgf is required, and in this case, the power Approximately 25Kg to 30Kg is required, and when you add in the weight of the latching machine itself, which is approximately 15Kg, the weight becomes large and it becomes inconvenient to handle. For this reason, it is impossible to integrate the lashing machine and the self-propelled machine, and they must be separated.

(Means for solving the problem) This invention was made in view of these points, and a drive source is provided at a distance below the drive wheel mounted on the messenger wire in a self-propelled machine, A space is created between these, that is, directly below the drive wheel, and the cable from the moving metal wheel is passed through this space and guided to the leading part of the lashing machine at the rear.

The structure of this invention is that drive wheels to be placed on the messenger wire are provided at the front and back of the center of the upper part of the main body, and a drive source body is provided at the bottom of the main body at a distance from the drive wheels. A transmission mechanism for transmitting power to the rotational drive of the drive wheel is provided on one side of the left and right sides of the main body, and a space for passing a cable through the main body in the front-rear direction is provided directly below the drive wheel, and a transmission mechanism is provided in the center of the front and rear drive wheels. A brake device is provided on the body, the drive wheel is configured to sandwich the messenger wire from above, and the brake is from below, and a device that slides vertically closes one side of the cable insertion space on the other left and right sides of the main body. It is equipped with a door that can be opened and closed freely.

(Function) The self-propelled machine of this invention has a driving wheel hung on the messenger wire, thereby suspending the self-propelled machine on the messenger wire. When the drive source body is actuated, the drive wheel rotates via the transmission mechanism, and as a result, the self-propelled machine travels while being suspended from the messenger wire. At this time, a braking action is performed by the brake device installed in the center of the front and rear drive wheels, so that the drive wheels do not spin idle. Furthermore, since the messenger wire is held between the front and rear drive wheels and the brake device, the self-propelled machine does not come off from the messenger wire. When towing the rear lashing machine, open the opening/closing door to the cable insertion space directly below the drive wheel of this self-propelled machine, insert the multi-strand cable, and then close the opening/closing door to remove the cable from the self-propelled machine. It prevents it from coming off and allows it to be introduced into the leading part of the rear lashing machine.

send to. At that time, the cable 57 is connected to the main pillar 3 on the left and right.
Since it is blocked by the opening/closing door 8, it cannot come off from this self-propelled machine.

Further, when these cables 57 pass through the space 32, they come into contact with the upper horizontal rollers 7 provided on the front and rear sides of the lower part of the space 32, and because they pass through while rotating these horizontal rollers 7, the cables 57 are not damaged. Furthermore, if other tracks (not shown) below this messenger wire 51 are close to each other, there is a risk that this self-propelled machine will hit the other tracks. A lower lateral roller 2 is provided at the lower end of the side, so that even if it comes into contact with another track, it will not damage the other track.

(Effects of the invention) This invention has the above-mentioned configuration. When pulling the lashing machine and introducing a multi-strand cable into the lashing machine, the cable is inserted just below the drive wheel placed on the methsenger wire. Therefore, unlike when cables are passed under conventional self-propelled aircraft, the cables do not hang downward and there is no risk of them coming into contact with the tracks below and damaging them. In addition, the cable is supported by the movable safe in front of the mobile machine, the lower body of the space of this self-propelled machine, and the leading part of the lashing machine, so the cable can be moved gradually closer to the messenger wire from the mobile metal car to the leading part. This prevents the cable from bending unnecessarily and causing damage to the cable. In addition, a braking action is provided by a brake device provided at the center of the front and rear drive wheels, so that the drive wheels do not spin idle.
Moreover, since the messenger wire is held between the front and rear drive wheels and the brake device, the self-propelled machine cannot be detached from the messenger wire. When towing the rear lashing machine, open the opening/closing door to the cable insertion space directly below the drive wheel of this self-propelled machine, insert the multi-strand cable, and then close the opening/closing door to remove the cable from the self-propelled machine. It has advantages such as preventing it from coming off.
