Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a carrier device for various working equipment for tension-resistant insulator chains, and is configured to be mounted on the insulator chain and self-propelled on the same insulator chain by remote control.

As working equipment for tensile insulator chains, there is generally a cleaning device for cleaning the insulators, which is also broadly classified into brush cleaning and water spray cleaning.

In addition, there are horn detectors for detecting defective insulators, and by equipping the device of the present invention with these devices depending on the purpose, it is expected that workability will be improved and safety will be ensured more than ever before. It is possible.

For example, when it comes to cleaning insulators, instead of the traditional method of having workers wash each insulator one by one using a washing machine attached to the tip of an insulating rod, this can now be done automatically using remote control. , it is clear that it is much more convenient and advantageous from the point of view of safety.

In particular, as insulator chains are becoming increasingly longer and longer due to ultra-high pressures, we should move towards automation.

In response to such demands, automatic cleaning devices have been proposed, but the problem lies in their transportation means, especially their transportation means.

It must be possible to move to the target location as quickly and stably as possible.

Unlike in other cases, it is necessary to move using an insulator chain in the air as a guide, so the requirements for speed and stability of movement become even more difficult.

This invention was made in response to such demands, and aims to provide a carrier device that can continuously move on a single insulator chain and can guarantee stable movement. It is.

The gist of the present invention is to provide a machine frame formed in an inverted U-shape so as to have a horizontal bar spanning at least two front and rear insulators, which are charged into a single insulator chain from above, and this machine frame. A carrier device capable of moving an insulator chain, comprising an elastic endless belt stretched in the length direction of the insulator chain and having an elastic convex portion that engages with the top of the outer periphery of an insulator umbrella part, and a motor for driving the belt. An embodiment thereof will be described below with reference to the drawings.

1 is the machine frame, which includes an inverted U-shaped vertical bar 1a and a straight horizontal bar 1.
It consists of a frame body with b.

The horizontal bar 1b is inserted into the insulator chain A from above in its length direction, and has a length such that it spans at least the two front and rear insulators.

A water tank 2 or the like is attached to the lower part of the machine frame 1 as necessary for balance.

In the center of this machine frame 1, a slightly wide endless belt 3
is installed between Boo IJ-4 and 5.

The endless belt 3 is made of an elastic material such as synthetic rubber, and has uneven anti-slip portions 3a on its outer peripheral surface, and elastic convex portions 3b that are protruded or raised at intervals of approximately one insulator. has.

The plurality of elastic protrusions 3b sequentially engage with the top of the outer periphery of the umbrella part a of the insulator by their rotation, thereby moving the machine frame 1 in the longitudinal direction of the insulator.

Fluid or electric motor 6 that can be remotely rotated in forward and reverse directions
is provided on the base T of the machine frame 1, and the pulley 4 or 5 is driven by an appropriate transmission mechanism 8.

The carrier device configured in this way has a single insulator chain A.
The endless belt 3 mounted on the top of the insulator umbrella part a is provided in a direction perpendicular to the insulator umbrella part a, and by rotation of the elastic convex part 3b, it sequentially engages with the top of the outer periphery of the umbrella part, and uses this as a point of reaction force to continuously move forward or You can retreat.

Moreover, during this forward or backward movement, the machine frame 1 is mounted in a well-balanced manner astride two or more insulators at the front and rear, and the endless belt 3 is elastically and frictionally engaged with the insulator umbrella. Since it is in contact with the top of the outer periphery of a, it can move stably in the longitudinal direction of the insulator.

Therefore, by attaching, for example, a cleaning machine 10 as shown in the figure to the carrier device according to the present invention, automatic or semi-automatic cleaning of insulators becomes possible.

The detailed configuration of this washing machine 10 is as follows.

At the tip of the machine frame 1, there are sleeves 1 at the left and right positions when viewed from the front.
1 are fixed to each other, and an elevating frame 12 is inserted into the sleeve 11 so as to be slidable in the vertical direction.

A semicircular or larger rail frame 13 with a lower opening slightly larger than the insulator diameter is integrally provided between the left and right lifting frames 12, and the rail frame 13 fits around the outer periphery of the insulator umbrella part a with a margin, and the lower part is opened slightly larger than the insulator diameter. The cleaning machine 10 is configured to rotate as described below.

Further, the machine frame 1 has water tanks 2 on the left and right sides for stability, and the water tanks are connected to an upper surface nozzle 14 and a lower surface nozzle 15 provided on the washer 10 by a flexible tube 16 midway.

Furthermore, in order to move the washing machine 10 mounted as described above on the front of the machine frame 1 up and down perpendicularly to the insulator chain by remote control, a lever 17 is mounted on the top of the machine frame 1 with a pin 18 for pivoting. The tip of the lever is connected to the rail frame 13 to move it up and down, and one end of an insulating string or tube 19 is tied to the rear end of the lever, and the other end is connected to the rail frame 13 to move it up and down. The operator pulls or relaxes to perform remote control.

That is, when the string or tube 19 is pulled, the washer 1
0 drags the rail frame 13 and the lifting frame 12 and rises perpendicularly to the insulator chain. In this state, the machine frame 1 is allowed to move the insulator chain by itself and is stopped at a desired position, and then the string or tube 19 relax.

Since the washer 10 is lowered perpendicularly to the insulator series by loosening the string or tube 19, both of the washer 10 can be attached to the insulators at desired positions.

Note that the tube 19 can also be used as a conduit for working fluid by extending its tip and connecting it to an air motor, etc., which will be described later.

After the cleaning machine 10 is attached to the insulator, it is configured as follows, for example, in order to rotate the cleaning machine 10.

As is well known, the cleaning machine 10 includes a removable frame body 10a that is attached to an insulator, at least two sets of upper brush groups 10b that are attached to the frame body at 180 degrees opposite positions, and when installed. Inner brush group 10c in an upright state
and a required number of guide rollers 10d, etc., and the nozzle 14 is arranged near the upper brush 10b and the lower brush group 10c via a water stop valve. 13 so that it rotates along
The frame body 10a is provided with semi-circular rotating frames 10e each having a T-shaped cross section (including those with alternating square sections) that engage with the grooves 13a of the rail frame 13. String 20.2 on both ends
0' are tied together, and the other ends of these strings are tied at winding rates 22, 22' at the top of the frame 10a via deflection rollers 21, 21'.

Further, an air motor 23 is fixedly installed on the frame 10a, and a rotating shaft 2 is driven by the air motor via a reducer 24.
5 loosely supports one winding rate 22, and a transmission shaft 29, which is synchronously interlocked with the same rotating shaft by a driving pulley 26, a belt 27, and a driven pulley 28, supports the other winding rate 22.
′ is loosely supported.

An intermediate shaft 30 provided between the two windings 22 and 22' is provided with a drive pulley 31 separately attached to the rotating shaft 25 and a driven pulley 33 with a belt 32 hooked therebetween to further reduce the speed.

Clutch plates 35 and 35' are fixed to the rotating shaft 25 and the transmission shaft 29, respectively, with the clutch plates 35 and 35' facing one side of the winding ratios 22 and 22' which are biased by springs 34 and 34'.

Each clutch plate 35, 35' has a required number of protrusions 36.
36', and is engageable with holes 37 and 37' provided on opposite sides of the winding rates 22 and 22'.

Then, the cam plate 38, which is always interposed between these winding rates and the clutch plate, is fixed to the intermediate shaft 30, and the cam plate is made thin in the approximately semicircular part and thick in the remaining part. By forming the clutch plate in the same direction, the clutch plates can be automatically engaged and engaged alternately by rotation in the same direction.

In the figure, 39 is the mounting base of the drive device of the above-mentioned washing machine, and 4
0 is an inlet for supplying makeup water to the water tank, and a check valve is installed inside.

41 is a lever for raising and lowering the lower brush group.

In addition, 1c is a part bent outward from the lower end of the machine frame 1, on which the water tank 2 is placed, and even if the machine frame 1 should be turned over, it can be placed outside the water tank 2. The protruding part comes into contact with the adjacent insulator to prevent it from falling over.

In this way, the cleaning machine 10 can be attached to an insulator at a desired position by remote control, the insulator can be cleaned, and this can be repeated by moving it over the insulator chain A, thereby saving labor for cleaning the insulator. Can be carried out efficiently and safely.

Moreover, by using the carrier device according to the present invention, working equipment such as a washing machine can be quickly transported using the insulator chain A as a guide, and stable transport using the endless belt 3 is also possible.

That is, since the elastic convex portions 3b of the endless belt 3 are made to sequentially engage and move with the tops of the outer periphery of the insulator umbrella portion a, the insulator chain A
Even if the carrier device is curved downward, the elastic convex portion 3b reliably engages with the insulator umbrella portion a, so that the continuous movement of the carrier device is not impaired and is smooth.
