Description

[Detailed explanation of the invention] (a) Technical field This invention relates to a spacecraft used to travel on overhead wires strung between steel towers.

(b) Prior art and problems Various types of aerial vehicles have been known to be used when moving on overhead wires, and recently there are those that are indexed by a powered tug,
An increasing number of spacecraft are installing small engines directly, but the overall weight of these spacecraft is heavy, and the work of attaching them to the overhead wires installed high on the tower is correspondingly difficult. For this reason, as a spacecraft that often works at high altitudes such as in mountainous areas, it is required to be small and easy to install, and also be able to perform reliable braking operations, giving a sense of security. There is a desire for a spacecraft that provides the following, and as far as the inventors of the present invention are aware, it seems that there are still few that are satisfactory.

(c) Purpose of the invention This invention was made with a focus on such conventional spacecraft, and it is lightweight as a whole, easy to install on the helix, and can perform reliable braking operations. The aim is to provide a spacecraft.

(d) Structure of the invention In order to achieve the above object, the spacecraft according to this invention has a pair of wheels placed on overhead wires, a pair of vertical frames that rotatably support the wheels at the upper part, and a horizontal frame at the bottom of the pair of wheels. The base frame is connected integrally with the base frame to form a reverse gate shape, and the base frame is vertically connected to the horizontal frame in a direction perpendicular to the horizontal frame, and is vertically suspended from the center of the horizontal frame so that the vertical height of the horizontal frame can be adjusted. an L-shaped hanging arm, a seat attached to the horizontal lower part of the hanging arm in a state perpendicular to the horizontal frame, and a backrest belt with both ends secured to the horizontal frame;
It is also equipped with a brake shoe that can be moved up and down manually to clamp the overhead wire in the vertical direction, and a brake means provided close to one of the wheels.

(E) Examples The details of this invention will be explained below with reference to the drawings.

1 to 3 are diagrams showing an embodiment of this invention.

Roughly speaking, the spacecraft 1 is composed of a pair of wheels 3 and 4 mounted on an overhead wire 2, a base frame 5, a seat 6, and a brake means 7.

A pair of wheels 3 and 4 are placed on the overhead wire 2 to suspend and support the entire spacecraft 1 and move it along the overhead wire 2, and are provided with grooves corresponding to the cross-sectional size of the overhead wire 2.

The base frame 5 includes a pair of vertical frames 8a,
8b and the horizontal frame 10 are integrally connected as a whole in a reverse gate shape, and the vertical frames 8a,
8b rotatably supports the wheels 3 and 4 at its upper part, and is connected to the horizontal frame 10 at its lower part. Then, in order to install wheels 3 and 4, the shaft 1
3. A nut 15 and mounting frames 16 and 17 are used. In addition, 14 is a bearing of the wheels 3 and 4. At the center of the horizontal frame 10 is a seat 6, which will be described later.
A pair of mounting rings 22 for connecting to a connecting portion 21 of a backrest belt 20 are fixed to the left and right sides. Reference numeral 23 denotes hooks which are respectively attached to the lower portions of the pair of vertical frames 8a and 8b for hanging cargo and tools.

The seat 6 is a horizontal frame 10 of the base frame 5.
It is attached via an L-shaped hanging arm 24 so as to be rotatable and height adjustable with respect to the central portion of the body. That is, the mounting bracket 19 is formed into a horizontal U-shape that embraces the horizontal frame 10, and the upper part 26 of the hanging arm 24 is inserted upward from the lower side into the insertion hole 18 provided therein. By selectively inserting the pins 27 into a plurality of pin holes 28 that are passed through and protruded and provided in advance, the L-shaped hanging arm 24 is made rotatable on a horizontal plane and freely adjustable in height. I try to keep it. Furthermore, the seat 6 is attached by fitting the mounting hole at the center of the reinforcing rib 6a on the lower surface side of the seat 6 into the horizontal lower part 25 of the hanging arm 24. Therefore, since this seat 6 is attached to the base frame 5 in a cantilevered manner and is supported only at the center, the worker (not shown) sitting on the seat 6 can feel the pain between his or her knees. Hanging arm 2
4, the position is stabilized, and the overhead wire 2 can be easily grasped with both arms.

The "braking means" is a brake shoe 29 that is placed close to one wheel (the right wheel 4 in the illustrated example), facing the wheel 4, and manually movable up and down to clamp the overhead wire 2. Specifically, the "brake means" is mainly composed of a guide frame 30, a frame plate 31, and a lifting device 32.

The guide frame 30 has a U-shaped cross section to maintain strength, and is installed upright on the horizontal frame 10 close to one wheel 4 (on the right in FIG. 1) and is mounted to support the wheel 4. It is connected to and supported by the protrusion 33 of the frame 17.

The frame body 31 has an opening 34 in this guide frame 30.
It is composed of a base part 36 supported vertically on a side edge 35, upper and lower horizontal frames 37, 38, and a vertical frame 39 integrally provided on the base part 36.

The lower horizontal frame 38 is provided with a receiving box 41 in which a rubber body 40 as a brake shoe 29 can be freely replaced.
In the illustrated example, a rubber body 40 is attached to a receiving box 41, and this rubber body 40 cooperates with wheels 4 to securely clamp the overhead wire 2 by slightly shifting the upper and lower clamping positions in the longitudinal direction of the overhead wire 2. I have made it possible.

The vertical frame 39 has a hinge pin 42 at the tip of the lower horizontal frame 38.
is rotatably connected via the upper horizontal frame 37.
It can be opened and closed freely by a pin 43 provided at the tip of the wire, and an overhead wire can be inserted when it is in the "open" state.
This prevents the overhead wire from coming off when it is in the "closed" state. In addition, 47 is a rubber plate for preventing damage when the frame 31 and the overhead wire 2 come into contact.

In the lifting device 32, a threaded support rod 46 with a manual handle 45 is rotatably screwed into a mounting frame 44 provided at the upper part of the guide frame 30, and this support rod 46 is rotatably attached to its lower end. The connected frame 31 can be moved up and down according to the rotation of the manual handle 45 and the support rod 46.

Next, the effect will be explained.

In order to install it on the overhead wire stretched between the steel towers, first, the installation height of the seat 6 is adjusted to an appropriate position by adjusting the position of the pin 27 of the hanging arm 24 according to the height of the operator. Next, rotate the manual handle 45 of the lifting device 32 provided on the base frame 5,
The position of the frame 31 is adjusted to the thickness of the overhead wire 2 so that it can be easily held together with the wheels 3 and 4, especially the adjacent wheel 4, and the vertical frame 39 is moved by operating the pin 43 so that the overhead wire 2 can be inserted. Allow it to be in the "open" state. Then, the overhead wire 2 is inserted into the frame 31 in the "open" state, and then the vertical frame 3
9 is brought into a "closed" state to ensure that it does not come off the overhead wire 2, and both wheels 3 and 4 are placed on the overhead wire 2, so that the spacecraft 1 can be moved freely on the overhead wire 2.
Next, by rotating the manual handle 45 of the lifting device 32 and lifting the frame 31, the rubber body 4
0, the overhead wire 2 is pressed against both wheels 3, 4, especially the wheel 4, and the overhead wire 2 is held down by the rubber body 40 and the wheel 4 from above and below to fix the spacecraft 1.

In order for the worker to get on and move over the overhead wire 2, he must first sit on the seat 6 and fasten the back support belt 20, since the height of the seat 6 has been adjusted in advance.
Each of the overhead wire 2 and the manual handle 45 is positioned at a height that is easy for the operator to operate. Then, according to the horizontal or inclined state of the overhead wire 2, the manual handle 45 can be operated to freely adjust the pressing force against the overhead wire 2, and the transition can be carried out manually while grasping the overhead wire 2 with both hands or one hand. be.

(F) Effects of the invention The spacecraft according to this invention is as described above, and has the following effects.

(a) Since the base frame is made up of a pair of vertical frames and one horizontal frame in the shape of an inverted gate, the structure is simple and lightweight, making it easy to handle when attaching to overhead lines between towers. is easy.

(b) Since the seat is installed on an L-shaped hanging arm suspended from the base frame, the worker can physically stabilize his or her posture by holding the hanging arm between his or her knees. At the same time, a greater sense of psychological stability can be obtained, and operability and work efficiency are improved.

(c) Since the hanging arm is rotatable in a direction perpendicular to the horizontal frame, the burden on the operator's movements is lighter.

(d) Since the vertical height of the hanging arm relative to the horizontal frame can be adjusted, the optimum seat height can be obtained according to the physique of the worker.

(f) Since the braking means is provided close to one of the wheels, it is easier to operate the brake when the overhead wire is moved by hand while sitting on the seat.
