Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a self-propelled flute machine for riding on conductors when attaching a subaser during overhead line work for multi-conductor power transmission lines.

Previously, the Sorahata machine of this age was Samurai Isoaki 54-134823.
There was something like this (Tsubaki Kosho No. 54-110521).

However, the driving devices for these vehicles were installed one each at the front and rear of the Chuuhata machine body. In this case, the drive device installed at the front in the running direction of the Chuqin machine will be able to obtain the specified driving torque, but the drive device installed later will be more suitable than the front drive device because the drive theory arrangement will be reversed. When the driving torque required for this type of fluehead machine is insufficient because the driving torque cannot be obtained, or when climbing a conductor with a steep slope,
The drive wheels sometimes slipped. In addition, if the conductor gripping force is increased to prevent slippage in the drive theory, the conductor may be damaged or untwisted, resulting in disordered conductors, and the gripping force increases the running resistance, which offsets the driving torque. There were drawbacks. The object of the present invention is to eliminate and improve the drawbacks of such conventional products, increase the driving torque, and reduce damage to the conductor.

Aspects of the invention will now be described in detail with reference to an embodiment illustrated in the accompanying drawings. As shown in the figure, this embodiment is a braking system in which a conductor 1 is pressed or clamped by a main body 3 rotatably provided with a plurality of rollers 2 arranged to correspond to the line spacing of a multi-conductor power transmission line and suspended around the conductor 1. A power unit to which a device 4 is attached, an engine 5, an oil pump 6 operated by the engine, a device 7 for controlling the pressure oil generated by the oil pump, and a hydraulic motor 8 that rotates a drive mechanism 9 using the pressure oil. is loaded on the main body 3, and a plurality of drive wheels 9, 9 rotated by the hydraulic motor 8, or an arm 11 provided with a plurality of drive wheels 9 and an auxiliary wheel 10 arranged at a predetermined interval, and one end of the arm 11. The main body 3 has a structure in which a plurality of drive devices 13 each comprising a gripping mechanism 12 that connects parts and moves the parts up and down are attached to one side of the main body 3 in the running direction.

The frame body 3 has a pillar 20' on one side in the running direction, and a plurality of conductors 1.
A roller 2 is provided on each of the pillars 201 on the pond side, and a low foot 2 is provided on the entirety of the conductor 1, and the lower end of each pillar 20' is pivoted to the frame 19, and the roller 2 is mounted on the pole 201. When the conductor 1 is also hooked up and removed, the support columns 20 are constructed so that they can be tilted to both sides.

The braking device 4 is provided in the main body 3, and is configured such that when the lever 2 wing is stepped on, the brake shoe pinches the conductor 1 from above and below.

The power unit consists of an engine 5, an oil pump 6, a control device 7, a hydraulic motor 8, a drive wheel 9, an oil tank 22, a pipe for circulating oil, and other adjustment equipment.The engine 5 operates the oil pump 6 to supply pressure oil. The vehicle is configured to travel by generating pressure oil from a control device 7 to a hydraulic motor 8 and rotating a drive mechanism 9, and operations such as traveling speed and switching forward/backward are performed through the control device hole.

The driving device 13 is attached to the frame 19 of the main body 3 by means of a screw-like 5 holder 16, and the sliding body 17 is screwed onto the screw shank 15 and the sliding body 17 is rotated by rotating the screw shank turtle 5. A gripping mechanism 12 is formed to move up and down, one end of an arm kametatami is pivotally connected to a sliding body 17 of the gripping mechanism 12 via a shaft 18, and two driving mechanisms S are attached to the arm il. . , a hydraulic motor 8 is directly connected to one drive mechanism 9.

It should be noted that even in the worst case, an interval close to one pitch means an interval close to one pitch, excluding the pitch interval, and it is most desirable if the interval is equal to one pitch. When using the present invention, ``with each support 20 tilted to both sides, the aerial machine is hoisted onto a power transmission line, and each roller 2 is placed around a predetermined conductor 11 by holding each conductor 1 from both sides. Then, the conductor 1 is gripped by the braking device 4 and the Miao Qin machine is parked.Next, the drive device 13 is set on the conductor 1, and the gripping mechanism 12 The slider 17 is moved downward by rotating the screw rod 15 of the arm 11. In this state, the conductor 1 is positioned between both drive wheels 9, 9. In this case, the drive wheel 9 located at the tip of the arm 11 is added to the top of the conductor 1, and the other driving mechanism 9 is positioned below the conductor 1. Thereafter, the screw thread 15 of the gripping mechanism 12 is rotated with a power wrench, hydraulic wrench, etc. to remove the bog body 17. When the arm 11 is raised, the base end of the arm 11 is lifted, and the lever action of the arm 11 causes both drive wheels 9
, 9 grip the conductor 1 from above and below. in this case,
The roller 2 adjacent to the drive wheel 9 presses down the conductor 1 from above and helps the conductor gripping force of the drive wheel 9 provided at the center of the arm. In this way, the drive devices i3 provided on both sides are set on the conductor turtle. Next, the engine 5 is started and the oil pump 6 is operated to generate pressure oil.

Thereafter, the brake device 4 is released and the lever of the brake device 7 is operated to send pressure oil to the hydraulic motor 8 to rotate the drive wheels 9, 9. Both driving wheels 9, 9 grip the conductor tortoise from above and below, and move along the power transmission line while pulling the whistle device main body 3.

When the Aircraft reaches the spacer installation position, the supply of pressure oil is stopped, the aircraft is parked, and the spacer installation work is carried out.

When the construction is completed, the train runs in the same manner as described above and repeats the same operation to install the baser from one steel tower side to the other steel tower side. The conductor gripping force by the drive device 13 can be adjusted by rotating the screw thread 15 of the gripping mechanism 12.
Adjustment is made by lifting the base end of the turtle upwards, but if this gripping force is insufficient, the two drive mechanisms 9, 9 will slip and will not advance. On the other hand, if it is too strong, the drive wheel 9
, 9 parts of the conductor 1 are bent significantly, which damages the conductor turtle, and the bending action acts to reduce the driving torque, resulting in loss of driving torque. Therefore, in the present invention, although the gripping force varies depending on the thickness of the conductor 1, the conductor 1 is gripped to such an extent that the conductor roof does not bend. Since it is used in an upwardly tilted state with the shaft 18 as a fulcrum, when traveling, the conductor gripping force is automatically adjusted for the following reasons, and the drive theory 9, 9 travels without slipping. The main body 3 of the flute drafting machine has a considerable weight due to its own weight, the weight of the worker, the engine, etc., and the load such as the subesa, etc., and a method of towing it by the drive device 13 is used. Therefore, when both drive wheels 9, 9 are rotated to apply a driving torque, the drive wheel 9, which is positioned at the tip of the arm 11, rotates in the direction of arrow B in FIG. The more the positioned drive wheel 9 rotates in the direction of arrow C and the more drive torque is applied, that is, the more the weight of the airborne machine body 3 expressed as a reaction in the direction of arrow A, or the steeper the climbing angle, the more In proportion to this, the two driving mechanisms 9, 9 strongly pinch the conductor 1 from above and below.Therefore, the arm 11, which is tilted upward, has an effect of spreading in the horizontal direction (progressing direction), and the conductor 1 The conductor gripping force due to the screw action increases between
The driving torque is transmitted efficiently.

As the construction progresses, the baser is installed, so the loaded weight gradually becomes lighter, and the required traction force also decreases, so the conductor gripping force is automatically adjusted to be weaker in proportion to this. It becomes like this. Further, in the present invention, the distance between the two drive wheels 9, 9 and the distance between one of the drive wheels 9 and the roller 2 adjacent thereto are arranged to be equal to or close to the twist pitch of the strands on the surface of the conductor. Since the wires on the conductor surface that the two driving wheels 9, 9 come into contact with each grip a separate wire while running, torque is distributed and averaged over the entire wire on the conductor surface, causing damage to the wire. There is no possibility of twisting or untwisting the wire by stretching it. The present invention is constructed as described above, and includes the whistle device main body 3.
A driving device 13 is attached to each of the left and right legs on the front side or the rear side in the running direction, and the main body 3 is pulled by the driving device 13, so that the main body 3 runs smoothly without twisting, and the driving torque of the two left and right units is tied. You can run and climb without slipping.

In addition, since the drive device 13 of the present invention is used with the arm 11 tilted upward, if the conductor 1 is gripped with a constant force, the rest will be automatically controlled depending on the weight of the whistle drafting device body 3 and the tilt angle of the power transmission line. In other words, the gripping force is adjusted to the optimum state, so that the driving wheels 9 can run smoothly without slipping and without damaging the conductor. Further, in the present invention, the distance between both drive wheels 9, 9 or the distance between one drive wheel 9 and the roller 2 adjacent thereto is arranged in relation to the twist pitch of the conductor 1, so that the conductor 1 is not damaged during running. It has remarkable effects such as no twisting or disordered twisting.

In addition, in the description of the above-mentioned embodiment of the present invention, the driving device 13 is shown towing the main body 3 of the seedling machine, so the driving device 13 is also placed in front of the main body 3 in the running direction. , which is the common usage of the traction method.

However, there are various cases in which power transmission lines are constructed in mountainous areas. For example, near the top of a mountain, power lines have a steep slope. In this case, it is customary to fire the fuehata machine by launching it from the side of the steel tower located high up. Therefore, a large amount of driving torque is not required for downhill travel, and rather, each drive device 13 is often attached to the rear part of the flute drafting machine body 3 in order to prevent the vehicle from going backwards if the vehicle goes too far. In this case, the drive torque of the drive device 13 is supposed to work efficiently toward the rear, that is, toward the mountain side, so when going down the power transmission line toward the valley, the drive section 9, 9 will not slip and run out of control. There's nothing to do. When the work begins to climb up the power line halfway, the load on the spacer has already decreased and the whistle has become lighter, so the drive device 13 on the low torque side moves the main body 3 backwards. Even if you push yourself up from the top, you can still climb the mountain easily.

If the drive torque is insufficient when the power transmission line becomes larger and the weight of the spacecraft increases, install drive devices 13 at the front and rear of the main body 3, and use the drive device 13 at the rear when the vehicle is on a downhill slope. In the case of an uphill slope, the front drive device 13 is operated, and if there is a shortage, the four drive devices 13 at the front and rear can be operated simultaneously.

FIG. 5 shows another embodiment of the drive device 13 of the present invention, in which a drive wheel 9 and an auxiliary wheel 10 are attached to an arm 11 at a predetermined interval, and a hydraulic motor 8 is attached only to the drive wheel 9.
The second embodiment differs from the first embodiment in that it provides a drive according to the above, but the other functions and effects are the same.

However, in this case, the driving torque will be lower than in a method in which drive is applied to both wheels. Various other design changes can be made without changing the spirit of the invention.
