Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spacer used when mounting a spacer or the like on a power transmission line during construction work for a multi-conductor power transmission line.

Since power transmission lines are often constructed in mountainous areas, the slope of the power transmission lines installed on them is steep due to the height difference between the towers (the maximum angle of inclination is 35 degrees, and the slope of the transmission line is steep, and the slope of the transmission line is steep due to the height difference between the towers). The maximum weight of workers, etc. will be approximately 350 Ky.

) When a worker rode out on a spacer to install a spacer on a power transmission line, the spacer was traveling so fast that it was difficult to stop it with normal brakes, and the worker had to repeatedly apply the brakes. If there was a problem, the function would be lost and the spacecraft would travel at breakneck speed, posing the risk of causing a disaster that could threaten the lives of the workers.

In addition, when the spacecraft reaches an upward slope in the middle between the steel towers, conventionally the worker has to row it by hand or pull it with a rope from the steel tower in front of it.

Alternatively, an engine was connected to the front of the spacecraft and when the vehicle approached an uphill slope, the engine was driven to pull the spaceship and travel, but these engines were only used when going uphill. However, when going downhill, the vehicle was stopped and idled, which increased the total weight of the spacer, spacer, tools, workers, and engine, making it difficult to unhook from the power lines, and making it even worse when going downhill. The disadvantage was that the brakes were unable to provide braking force due to weight acceleration.

The present invention eliminates and improves such drawbacks by providing a runaway prevention device on the spacecraft, which controls the traveling speed on downhill slopes, and applies reverse power to the runaway prevention device on uphill slopes to prevent the spacecraft from running. The purpose is to make the vehicle run.

Aspects of the invention will now be described in detail with reference to an embodiment illustrated in the accompanying drawings.

In the first embodiment of the present invention, as shown in the figure, a plurality of rollers 1 mounted on each conductor C of a multi-conductor power transmission line are each rotatably attached to a frame body 2 on which an operator rides.

In a spacecraft 4 equipped with a braking device 3 that controls or stops traveling by suppressing or clamping a conductor C by a person's operation, a shaft 6 of an input pulley 5 that rotates in contact with the conductor C and an output rotation shaft 7 and a speed increasing gear 8 having a ratio of approximately 1:20, the speed increasing gear 8 is housed in a case 9, and the case is filled with oil 18, and the output side rotating shaft 7 in the case A blade 10 is attached to the blade 10 so that the blade 10 agitates the oil, and a disk 11 is attached to the output side rotation shaft 7 protruding from the case 9.

A runaway prevention device 13 equipped with a brake device 12 that clamps the airborne vehicle 11 is attached to the airborne vehicle 4.

In order to prevent the input pulley 5 from slipping with the conductor C, an anti-slip device 14 made of urethane rubber or the like is provided around its circumference.
Further, a fastening means 17 is provided between the connecting arm 19 that connects the escape prevention device 13 to the frame 2 and the lever 15 that supports the auxiliary roller 16, and the fastening means 17 is connected to the bolt 1.
One end of 71 is coupled to the connecting arm 19, the other end is inserted into a ring member 172 provided on the lever 15, and the nut 1 is inserted into the ring member 172.
By screwing and tightening 73, the input pulley 5
and the auxiliary roller 16 to sandwich the conductor C,
The contact between the input pulley 5 and the conductor C is strengthened to prevent slipping.

The blades 10 provided on the output side rotating shaft 7 stir the oil 18 filled in the case 9 and use the viscous resistance or fluid resistance to control the rotation of the output side rotating shaft 7 within a predetermined number. .

The rotation speed may be arbitrarily determined by changing the viscosity of the oil 18 or by changing the number, angle, and shape of the blades 10.

The present invention is constructed in a diagonal manner, and the escape prevention device 13
The escape prevention device 13 is attached to the spacecraft 4 by attaching it to the connecting arm 19 and connecting one end of the connecting arm 19 to the frame 2.

To hang the air carrier 4 on the conductor C of the power transmission line, remove the connecting rod 21 of the frame 2, tilt the frames 22 and 22 on both sides in the direction of arrow A on the outside of each can, and connect each conductor C from the outside. Carry it into both frames 22.22 while holding it in both frames 22.
．． 22 is returned to its original state and each roller 1 is mounted on the conductor C.

At this time, the input pulley 5 of the escape prevention device 13 and the auxiliary roller 16 clamp the conductor C located there with the fastening means 17.

In this state, the worker gets on the air ride 4 and rides out on the power transmission line, but since the slope is downward to the center between the towers, the runaway prevention device 13 follows the movement of the air ride.
The input pulley 5 rotates, the output rotation shaft 7 rotates at an increased speed of about 20 times, and the blade 10 provided thereon rotates with the oil 1.
8 is agitated and the rotational force of the shaft 7 is suppressed by the viscous resistance or fluid resistance to keep the rotation of the input pulley 5 constant, and if necessary, the disc 11 provided on the output rotation shaft 7 is braked. It is clamped by a device 12 and its rotation is controlled.

As shown in FIG. 3, in this brake device 12, a grip body 123 having grip rods 121, 122 on both sides is placed on a case 9 at a position where the disk 10 fits between both grip rods 121, 122. A fixed pad 124 is provided on the inside of one of the gripping rods 121, a movable pad 125 is provided on the inside of the other gripping rod 122, and a bundle 126 for taking in and out the movable pad 125 is provided on the outside. On the other hand, when it is rotated clockwise, for example, the movable pad 125 is pushed out by a built-in screw mechanism, and the disc 11 is sandwiched between the fixed pad 124 and the rotation is controlled. Even if the 12 handles 126 are directly operated by hand, the handles 12 may
Connect one end of a wire or cable to 6, provide a lever, etc. at the other end, and attach it to a designated part of the frame 2 of the spacecraft.
The lever can also be operated remotely.

The relationship between the travel speed and travel distance of the spacecraft and time is determined by the gear ratio of the runaway prevention device 13, so it depends on the application and
Runaway prevention device 1 whose gear ratio is adjusted according to usage conditions
It is better to use 3.

In this way, by the action of the runaway prevention device 13, the spacecraft travels on the conductor C of the power transmission line while its traveling speed is controlled (within 5 m/s), and when it reaches the predetermined position to attach the spacer, it stops in the air. The brake device 3 of the spacer vehicle 4 or both the brake device 3 and the brake device 12 of the escape prevention device 13 are operated to stop the travel of the space vehicle 4, and spacer installation work and other work are performed.

When these operations are completed, both brake devices 3 and 12 are released, and the spacer vehicle starts traveling at a constant speed again. From then on, this process is repeated to advance the spacer vehicle 4.

When the spacecraft approaches an uphill slope, the tightening device 17
If the input pulley 5 is loosened and removed from the conductor C, the escape prevention device 13 will no longer operate, so the operator must hold the conductor C while rowing and move the spacecraft forward, or It will be pulled by a rope extended from the steel tower and will carry out work such as spacer installation.

Normally, in power transmission line construction work in mountainous areas, spacer installation work is carried out using a spacer from the higher tower side, so the transmission line between the towers has a downward slope ratio. Since it is a dog, the power burden on the worker is relatively small compared to when working on an uphill slope.

The present invention provides a runaway prevention device 13, and uses the viscous resistance or fluid resistance of the oil 18 by the blades 10 and the brake device 12 of the disc 11 to control the airborne vehicle to a traveling speed of 5 m/s or less, and further, if necessary, Since the braking device 3 of the space vehicle is also operated to maintain the running speed of the space vehicle constant, the burden on the brake device 3 of the space vehicle is reduced, and the stopping action can be performed reliably, and the space vehicle is It has remarkable effects, such as protecting the safety of workers, reducing their mental and physical burden, and allowing them to complete specified construction work without running out of control.

In the explanation of the above embodiment, a disc 1 is attached to the output side rotating shaft 7.
1 and the brake device 12 that clamps the disc 11 is also explained, but it goes without saying that the object of the present invention can be achieved even if this is not necessarily provided. do not have.

FIG. 4 shows a second embodiment of the present invention, in which two input-side boots IJ-5, 5 of a run-away prevention device 13 and an auxiliary roller 16 for preventing their slipping are used to contact a plurality of conductors C. so that it rotates, and the shaft 51 of the boo IJ-5, 5
This embodiment differs from the first embodiment in that the input rotating shaft 6 and the input rotating shaft 6 are rotatably coupled by a gear 52 or other means, but the other functions and effects are the same.

In this case, the escape prevention device 13 is attached to the central part of either the front or rear of the spacecraft 4 in the direction of movement, and the input side boot IJ-5
, 5 rotate in contact with the plurality of conductors C2C on both sides, so when the brake is applied by the escape prevention device 13 while the spacecraft 4 is running, it will not be pulled to one side as in the first embodiment. No deformative distortion occurs in the spacecraft.

Further, in another embodiment described later, when the output side rotating shaft 7 and a motor etc. are connected and driven to run the spacecraft on an uphill slope, the power is transmitted by both the boots IJ-5, 5 without slipping. It can be made to work reliably.

FIG. 5 shows a third embodiment of the present invention, in which a blade 101 is attached to the output rotating shaft 7 outside the case 9 in place of the oil stirring blade 10, and the air resistance caused by the rotation of this blade is utilized. Although the running speed of the spacecraft is adjusted by controlling the rotation of the output side rotating shaft 7, the effect is the same.

FIG. 6 shows a fourth embodiment of the present invention, in which a centrifugal brake device 111 is provided in place of the disk 11 and brake device 12 provided on the output side rotation shaft 7 of the runaway prevention device 13. The running speed of the spacecraft is adjusted by controlling the rotation of the spacer, but the effect is the same.

FIG. 7 shows a fifth embodiment of the present invention, in which a DC motor 112 is coupled to the output side rotating shaft 7 of the escape prevention device 13, a load is connected to the power source side of the motor 112, and the input side pulley 5 When rotation is applied to the motor 112 through the output-side rotation shaft 7, the motor 112 enters a power generation state, and uses its regenerative braking to apply resistance to the output-side rotation shaft 7 to control its rotation, thereby increasing the traveling speed of the spacecraft. I'm trying to adjust it.

In this case, by changing the capacity of the load, the regenerative braking capacity, that is, the rotational resistance of the shaft 7 can be increased or decreased to adjust the traveling speed.

Further, as will be described later, when the motor 112 is used as a power source, the power source 113 can be charged by this power generation capacity.

The fifth embodiment has been described above in which the motor 112 is installed and its regenerative braking is used to control the rotation of the output rotating shaft 7 to adjust the traveling speed of the spacecraft. As an example of using a motor,
When this motor 112 is used as a driving power source for the spacecraft on an uphill slope, a power source 113 is connected to the motor 11.
When power is supplied to 2, the motor 112 starts and its rotation is transmitted to the input pulley 5 as decelerated power, and the pulley 5 drives the conductor C of the power transmission line while causing the spacecraft 4 to travel. I can do it.

When the motor 112 is coupled to the output rotating shaft 7 of the runaway prevention device 13 whose speed has been increased in this way, the motor 112 performs a regenerative braking operation when used on a downhill slope, and when the slope is uphill, the motor 112 performs a regenerative braking operation. By supplying electric power to it, it acts as a decelerated reverse power to drive the spacer, which has the effect of eliminating the power required by the operator to move the spacer.

It is also possible to use an engine in place of the motor 112, but in this case it will be bulkier than the motor.

8 to 9 show a sixth embodiment of the present invention,
A plurality of rollers 1 mounted on each conductor C of a 6-conductor power transmission line are each rotatably attached to a frame 2 on which a worker rides, and the conductor C is suppressed or clamped by the worker's operation to control or stop the running. In the air vehicle 4 equipped with the braking device 3, the two escape prevention devices 13 and 13', each of which rotates by contacting the two conductors C arranged in the horizontal direction, are each attached to the air vehicle 4. The 6-conductor power transmission line spacer is itself large in size and heavy, and it is inevitable that it will have a large number of loading equipment such as spacers and other construction tools, making the total weight considerably large.

Therefore, the difference from the first embodiment is that two runaway prevention devices 13 are arranged on both sides and attached to the air vehicle to further prevent the air vehicle from running out of control and allow safe travel. The structure, function, and effect of the escape prevention device 13 itself are the same.
