Description

[Technical field]

[0001] The present invention relates to a tool for guiding objects while avoiding linear obstacles, and in particular to a tool for wiring objects such as cables, call lines, and flexible electric wire pipes between the reinforcing bars (reinforcing bars) installed in the construction of buildings, etc., and a method for avoiding linear obstacles using the tool. [Background technology]

[0002] Generally, when wiring cables in a building construction project, the work is done by wiring the cables in the gap between the rebars and the concrete floor, with the rebars already laid on the floor. This wiring work requires wiring in narrow gaps while avoiding the rebars, so workers have to bend down to wire the cables, or push one end of a long cable into the gap while avoiding obstacles, which is very tedious and hard work. If the cable is heavy and difficult to handle, it is common to wire a lightweight wire-like wiring guide in advance, tie the cable to one end, and pull the other end to wire the cable.

[0003] In addition, although it is different from reinforcement, devices such as those in Patent Documents 1 and 2 have been developed as tools for wiring additional cables while avoiding linear obstacles such as bundling hangers that have already been laid overhead, such as electric wires, and cable racks installed in the ceiling of a building.

[0004] The invention of Patent Document 1 is a wire pulling tool for passing a new cable through a bundling hanger that is wound in a spiral shape or the like around a support wire in order to bundle overhead cables, and has a towing part that engages with the tip of each columnar member of the rotary part so as to be able to swing freely, and an operator attaches a new cable or string to the rear end of the towing part and operates the operating rod to insert the towing part into the bundling hanger and operate the operating rod so that the wire pulling tool faces in a predetermined direction, whereby the bundling hanger enters from an entrance between the holding part and the towing part and exits from an exit between the holding part and the towing part as the rotary part rotates, and the towing part moves in a predetermined direction within the bundling hanger, and is characterized in that a sweeping fin is provided at the front lower part of the towing part to sweep aside cables already laid in the bundling hanger so that the cables do not get tangled between the holding part and the towing part as the towing part moves in the predetermined direction.

[0005] Furthermore, the wiring device of Patent Document 2 is a wiring device mainly for wiring linear members such as cables on a cable rack installed on the ceiling inside a building, and the main body has two members connected at a distance via at least three tiltable connecting bodies, and the connecting body is rotatably attached to one of the two members and has protrusions protruding on both sides at its tip and is movable between a release position where it tilts and releases the connection when an obstructing member that is an obstructing factor when the main body moves passes between the two members and comes into contact with them, and a connecting position where the two members are connected, and the protrusions engage with slits formed on the other of the two members to maintain the connected state, and this wiring device is characterized in that when one connecting body is released due to contact with the obstructing member, the connected state is maintained by the at least two connecting bodies.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] Hereinafter, the guide object guiding tool according to the present invention will be described with reference to the drawings. Fig. 1 to Fig. 4 are diagrams relating to Example 1, Fig. 5 to Fig. 12 are diagrams relating to Example 2, and Fig. 13 is a comparison diagram of the movement trajectories of the guide object guiding tools of Example 1 and Example 2. EXAMPLES

[0025] 1 to 4 are diagrams of an embodiment of the guide object guiding tool 10 of the present invention, which corresponds to claims 1 to 6 in the claims. The guide object guiding tool 10 is composed of a main body 20 and a guide plate 30. A guide rail 21, which is hollow and partially open like a curtain rail, is provided on the main body 20 in an arc shape. A rail 31 with an L-shaped cross section is provided on the guide plate 30 in an arc shape. The guide rail 21 supports and guides the rail 31, so that the guide plate 30 swings. The central part of the guide object guiding tool 10 is an opening A, and when the guide plate 30 swings in one direction, the opening A communicates with the outside, and the guide plate 30 passes through this part to capture a linear obstacle B. The material of the guide object guiding tool 10 is mainly made of resin, but is not limited to this and may be made of metal such as stainless steel.

[0026] As shown in Fig. 2, the main body 20 is configured with an arc-shaped guide rail 21 attached to a plate resembling the shape of an airplane wing. The center is an arc-shaped opening. The guide rail 21 is hollow like a curtain rail with a portion open, and this hollow portion supports and guides the rail 31 like a curtain runner. A handle connection portion 22 for attaching a handle (not shown) is provided at the top. In addition, the wing-like portions provided on both sides of the guide rail 21 serve as guide portions 23, and in the figure, they are shaped like an inverted triangular wing to make it easier to guide linear obstacles such as reinforcing bars into the opening A.

[0027] As shown in Fig. 3, the guide plate 30 is configured with an arc-shaped rail 31 attached to a plate resembling an inverted V. A towing point 31 for towing the guide object C is provided near the bottom end of the guide plate 30. The rail 31 has an L-shaped cross section and is provided in an arc shape. By inserting the rail 31 into the hollow portion of the guide rail 21 of the main body 20, the main body 20 supports the guide plate 30, and since it is arc-shaped, it is configured to swing along the track.

[0028] Also, the guide rail 21 of the guide plate 30 may be configured to oscillate more smoothly by arranging bearings (not shown) continuously in an arc shape.

[0029] Next, a method for towing and disposing the guide object guiding tool 10 while avoiding linear obstacles will be described with reference to Fig. 4. First, when a guide object C is attached to the towing point 31 of the guide plate 30 by a string or the like and is towed forward, the guide plate 30 naturally swings due to the weight of the guide object C and friction with the ground surface, and the side in the direction of travel opens. Linear obstacles B such as reinforcing bars are taken in from this opening and guided to the opening A.

[0030] Secondly, if the robot continues to move forward while keeping the linear obstacle B caught in the opening A, the linear obstacle B comes into contact with the inner wall of the guide plate 30, and the guide plate 30 is pushed by the linear obstacle B and begins to swing counterclockwise, as shown in the second diagram of Figure 4.

[0031] Thirdly, when the guide tool 10 advances further from the second state, the guide plate 30 swings and opens on the side opposite to the traveling direction. The linear obstacle B that has been taken in through this opening exits the guide tool 10.

[0032] Fourth, the weight of the guide C and friction with the ground surface naturally cause the guide plate 30 to swing, opening the side in the direction of travel and returning to the first state. By repeating this, the guide C can be easily placed while avoiding the linear obstacle B. EXAMPLES

[0033] 5 to 12 are diagrams of an embodiment of the guide object guiding tool 100 of the present invention, which corresponds to claims 7 to 11 in the claims. The guide object guiding tool 100 has a slide plate 110 as a main body, a guide plate 120 and a guide plate 130 for avoiding and guiding a linear obstacle B, a pulling plate 140 for attaching a guide object C, and a push-up plate 150 for assisting the swing of the guide plate 120. Although not shown, a spring is provided on the slide plate 110, which biases the guide plate 120 in the opening direction, that is, in the direction of pushing back the swing in the clockwise direction in FIG. 5(a).

[0034] The slide plate 110 has a sled-like shape as shown in Fig. 5, and is structured so that it can move smoothly in a straight line by abutting against the upper parts of the multiple linear obstacles B that are placed. In addition, the plate is hollowed out to reduce weight while maintaining strength. The length of the slide plate 110 can be determined according to the spacing between the linear obstacles B that are placed, but a length of about 150 to 400 mm is usually suitable for various situations and is easy to handle.

[0035] As shown in FIG. 6, the slide plate 110 is provided with a guide plate attachment portion 111 for attaching the guide plate 120 so that the guide plate 120 can swing, and a handle connection portion 112 for attaching a handle (not shown).

[0036] The guide plate 120 is an arc-shaped plate with an opening A in the center as shown in Fig. 7, and includes an arc-shaped hole 121 provided so as to be swingably attached to the guide plate attachment part 111, a guide plate attachment part 122 for swingably attaching the guide plate 130, and a push-up plate abutment part 123 for abutting the push-up plate 150 for assisting the swing. The guide plate 120 swings in the clockwise direction as shown in Fig. 7(a) when guiding the linear obstacle B to the opening A, and swings in the counterclockwise direction when the linear obstacle B reaches the opening A and is released from contact with the guide plate 120. As described above, a spring (not shown) is provided between the guide plate 120 and the guide plate attachment part 111, and biases the guide plate 120 to swing in the counterclockwise direction.

[0037] In addition, the guide plate 120 is provided with a wire connection portion 124, and by attaching a wire here, when an operator pulls the wire, the guide plate 120 is forcibly swung, so that the linear obstacle B can be guided to the opening A. Therefore, for example, when multiple linear obstacles B are arranged in a row, an avoidance and guidance operation can be performed all at once.

[0038] Guide plate 130 is composed of two members with an inverted L-shaped structure with an opening A in the center as shown in Fig. 5(a), and guide plate member 131 in Fig. 8 and guide plate member 132 in Fig. 9 are attached to be swingable so as to sandwich guide plate 120. The attachment points to guide plate 120 are arc-shaped rails 131a and 132a.

[0039] The guide plate 130 is configured to start swinging in the opposite direction to the guide plate 120, that is, the counterclockwise direction in Fig. 5(a) and Fig. 12(c) after the guide plate 120 starts swinging. This has the advantage that the guide plate 120 and the guide plate 130 perform an avoidance operation to pinch the linear obstacle B, eliminating the possibility of the tool falling off the linear obstacle B, and allowing the avoidance guide operation to be performed reliably.

[0040] In addition, the guide plate 130 is naturally forced to return to its initial position due to its own weight, the weight of the connected guide object C, and friction with the ground surface, so that when the linear obstacle B passes through the opening A, it has an excellent structure in which it completes its swing to the initial position without the need for spring force.

[0041] The towing plate 140 is a part for attaching the guide object C, and has a boat-like shape as shown in Fig. 10. In this embodiment, three guide objects C can be attached at once to the towing point 142. The towing plate 140 is rotatably attached to the rear side of the guide plate 130 in the tool travel direction by means of a towing plate attachment hole 141.

[0042] 11, the push-up plate 150 is a channel material with a U-shaped cross section, with a push-up plate mounting hole 151 provided at one end for rotatably mounting it to the slide plate 110, and a push-up plate abutment portion 123 of the guide plate 120 abutting on a U-shaped groove at the other end, thereby assisting the swinging of the guide plate 120. The push-up plate 150 may be configured to swing to the initial position by its own weight, or may be spring-biased.

[0043] Next, a method for towing and installing the guide object guiding tool 100 while avoiding linear obstacles will be described with reference to Fig. 12. Fig. 12(a) is a diagram showing the initial state, in which the tool advances to the left.

[0044] First, as shown in FIG. 12(b), the linear obstacle B first comes into contact with the lift plate 150 and starts to rotate counterclockwise.

[0045] Secondly, the guide plate 120 in contact with the push-up plate 150 starts to swing clockwise while being pushed by the push-up plate 150, thereby guiding the linear obstacle B to the opening A of the guide plate 120,

[0046] Thirdly, as shown in FIG. 12(c), after the guide plate 120 starts to swing, the linear obstacle B comes into contact with the guide plate 130, and the guide plate 130 starts to swing counterclockwise to guide the linear obstacle B to the opening A of the guide plate 130.

[0047] Fourthly, as shown in FIG. 12(d), when the linear obstacle B reaches the opening A of the guide plate 120 and the contact is released, the guide plate 120 swings in the opposite direction, that is, toward the initial position, due to the spring force, and the push-up plate 150 also rotates toward the initial position.

[0048] Fifth, as shown in FIG. 12(e), when the linear obstacle B passes through the opening A of the guide plate 130, the guide plate 130 swings in the opposite direction, that is, toward the initial position, and the series of obstacle avoidance operations is completed.

[0049] The trajectories of the movement of the guided object guiding tools in the first embodiment and the second embodiment are different as shown in Fig. 13. In the case of the guided object guiding tool 10 in the first embodiment, in order to smoothly guide the tool to avoid an obstacle, the operator moves the tool up and down. In the case of the guided object guiding tool 100 in the second embodiment, the tool is moved in a straight line over the linear obstacle B.

[0050] The guided object guiding tool 10 of the first embodiment has a relatively simple structure, is lightweight and compact, and excels in avoidance guidance in situations where the linear obstacles B are not regularly arranged and have different heights. The guided object guiding tool 100 of the second embodiment has a long slide plate, so that it can very quickly perform avoidance guidance in situations such as the reinforcement of a building where the linear obstacles B are arranged linearly at the same height. [Industrial Applicability]

[0051] The guide object guidance tool of the present invention is a tool for placing guide objects while avoiding linear obstacles such as reinforcing bars placed mainly near the floor surface, but is not limited to this and is a tool that can tow and guide guide objects while avoiding linear obstacles such as linear obstacles suspended in the sky or linear obstacles placed on wall surfaces.
