Description

  The present invention relates to a polishing apparatus, and more particularly to an apparatus for polishing using a polishing member such as an inner winding brush or a needle cloth having an inner peripheral surface for polishing an object to be processed such as a wire rope or an overhead power transmission line.

  Conventionally, wire ropes are used in applications such as guard rails and suspension bridges on highways, for example. Once installed, the wire ropes used in guardrails and suspension bridges are exposed to rainwater, atmospheric debris, salt, chemical substances, etc. for a long time after being installed.

  For this reason, corrosion of wire ropes used in guardrails and suspension bridges is unavoidable. If iron oxide (rust) is generated on the surface of the wire rope due to corrosion, the appearance of the wire rope deteriorates, and further If the attached part is left as it is, corrosion tends to proceed from the rusted part and may lead to deterioration of durability.

  Overhead power transmission lines are exposed to rainwater, atmospheric debris, salt, chemicals, etc., just like wire ropes used in guardrails and suspension bridges. There is a problem of deterioration of sex.

  Therefore, in the maintenance of objects to be processed such as wire ropes and overhead power transmission lines, an apparatus for removing dirt and rust on the surface of the objects to be processed is used.

  For example, Patent Literature 1 and Patent Literature 2 disclose an apparatus that removes foreign matter attached to an electric wire by polishing the surface of the electric wire with a rotating brush.

  However, in the apparatus disclosed in Patent Document 1, since the electric wire is polished by a pair of rotating brushes arranged on both sides of the electric wire, the surface of the electric wire facing the rotating brush and the other surfaces are used. Polishing is uneven and it is difficult to polish the periphery of the wire uniformly. Moreover, in the apparatus disclosed in Patent Document 2, since the electric wire is polished with the rotating brush arranged on the lower side of the electric wire, the upper side of the electric wire cannot be basically polished.

  Further, Patent Document 3 includes a cylindrical rotating brush assembly that rotates about the axis of a rope-shaped steel cable, and the steel cable is arranged in the cylindrical rotating brush assembly so that the surface of the steel cable is uniform. A maintenance device that can be polished is disclosed. A plurality of cylindrical brushes are rotatably attached to the rotating brush assembly of the maintenance device around the rotation axis of the rotating brush assembly at regular intervals.

  In this maintenance device, the rotary brush assembly and the housing that rotatably holds the rotary brush assembly are configured to be split into two so that the maintenance device can be attached from the side of the steel cable. Therefore, this maintenance device can evenly polish the area around the steel steel cable, and when the maintenance device is attached to the steel cable, the steel cable is placed in the rotating brush assembly and the housing to place the steel cable. There is no need to insert into the rotating brush assembly and housing from the end.

  However, in the maintenance device disclosed in Patent Document 3, a plurality of cylindrical brushes are rotatably attached to the rotating brush assembly, and when the rotating brush assembly moves relative to the steel cable, the cylindrical brush is universal. Since the cylindrical brush rotates and revolves so as to be in contact with the steel cable, the structure of the rotating brush assembly is complicated.

  Further, in the maintenance device disclosed in Patent Document 3, when the maintenance device is attached to the steel cable, the pair of divided pieces of the rotary brush assembly divided into two parts are arranged so as to surround the steel cable and then divided into two parts. It is necessary to arrange and couple a pair of divided pieces of the housing so as to surround the rotating brush assembly attached to the steel cable. Further, when the maintenance device is removed from the steel cable, the housing of the maintenance device is divided and removed from the steel cable, and then the rotary brush assembly is divided to find the dividing position of the rotary brush assembly and the steel cable is divided. It is necessary to remove from. Therefore, the maintenance device disclosed in Patent Document 3 has a problem that it is particularly troublesome to remove the maintenance device from the steel cable.

  Moreover, a wire rope and an overhead power transmission line may be installed in a place where it is dangerous to work manually. However, the polishing device disclosed in Patent Literature 1 and the maintenance device disclosed in Patent Literature 3 are manually moved, and the work itself for polishing steel cables and electric wires requires manpower. Not suitable for polishing installed wire ropes and overhead power lines. On the other hand, the device for polishing an electric wire disclosed in Patent Document 2 is a self-propelled type. However, in addition to the electric rotating brush for polishing the electric wire, an electric guide roller driving unit for self-propelling is separately required. .

The state fixed to EGp is shown. FIG. 30 is a view for explaining a method of using the polishing apparatus 3000 according to the third embodiment shown in FIG. 23, and shows a working state of polishing an object to be processed.

  A polishing apparatus according to one aspect of the present invention is a polishing apparatus in which an object to be processed is inserted into an annular polishing member and polished by an inner peripheral surface of the annular polishing member. The polishing apparatus includes a polishing member having an inner peripheral surface for polishing an object to be processed, a housing that rotatably holds the polishing member, and an object to be processed inserted into the polishing member by rotating the polishing member. And a driving unit that applies a rotational driving force to the polishing member so as to be polished on the peripheral surface. The polishing member and the housing are each configured to be split so that the polishing member and the housing are opened.

  Here, the object to be processed may be any object as long as it is polished on the inner peripheral surface of the polishing member while being inserted into the annular polishing member. An elongate member such as a power transmission line can be mentioned.

  The polishing member and the housing need only be configured to be split so as to open, and the division is not necessarily limited to two, but may be three or more. Since the polishing member and the housing have a structure that can be divided, it is not necessary to insert the elongated member from the end into the annular polishing member when the polishing device is attached to the elongated member that is the object to be processed.

  For example, when a polishing device is attached to a wire rope used as a guard rail on an expressway or the like, it is practically impossible to insert the wire rope from its end into the housing and the polishing member of the polishing device. Even in such a case, since the housing and the polishing member of the polishing apparatus can be divided so as to open, the polishing apparatus can be attached to the wire rope from the side surface of the wire rope.

  Further, the drive unit that applies the rotational driving force to the polishing member may be any device that applies the rotational force to the polishing member. For example, the drive unit includes a motor and is configured to transmit the rotational force of the motor to the polishing member, or includes a turbine and converts the compressed air into the rotational force of the turbine and transmits the rotational force to the polishing member. It is what I did. However, the mechanism for applying the rotational force to the polishing member is not limited to these.

  Moreover, it is preferable that the polishing apparatus of this invention is provided with the stop mechanism which stops the polishing member rotated by inertia after the drive part stops the application of the rotational drive force to a polishing member. This stop mechanism may be any mechanism that stops the rotation of the polishing member so that the inclination angle of the dividing surface of the polishing member with respect to the dividing surface of the housing becomes an angle within a predetermined angle range.

  A polishing apparatus according to another invention of the present application has an inner peripheral surface for polishing an object to be processed, and is configured to be separable so that the object to be processed is introduced into a space surrounded by the inner peripheral surface. And a moving means for moving the polishing part relative to the object to be processed so that the object to be processed is polished by the inner peripheral surface of the polishing part.

  Here, the polishing apparatus includes a base that is movably attached to the object to be processed and is configured to be capable of adjusting a frictional resistance with the object to be processed, and a controller that controls the polishing part and the base. The part may be configured to be movably attached to the object to be processed and to be capable of adjusting the frictional resistance with the object to be processed.

  In this case, the moving means only needs to be configured to relatively move the base portion and the polishing portion, and the control portion adjusts the frictional resistance at the base portion and the polishing portion and performs relative movement by the moving means. The control unit is configured to control the polishing unit so that the polishing unit polishes the workpiece by moving the polishing unit relative to the workpiece without moving the base relative to the workpiece. The mode and the movement mode in which the base moves are switched by adjusting the frictional resistance and controlling the moving means by moving the base relative to the workpiece without moving the polishing portion relative to the workpiece. If it was done.

  For example, in the polishing mode, the control unit reduces the frictional resistance between the base and the object to be processed so that the polishing part moves relative to the object to be processed by the relative movement between the base and the polishing part. The friction resistance between the base and the workpiece is set so that the base moves relative to the workpiece by relative movement between the base and the polishing portion in the movement mode. It can be set smaller than the frictional resistance between the workpiece and the workpiece.

  Any moving means may be used as long as it moves the base and the polishing part relatively. For example, various actuators such as a linear motor, a hydraulic cylinder, and a pneumatic cylinder can be used.

  In the polishing apparatus according to another invention of the present application, the moving unit may be a pulling unit that pulls the polishing unit so that the polishing unit moves relative to the workpiece. Here, the pulling means includes a wire connected to the polishing unit, a winding unit that winds the wire, and a direction conversion that converts the direction in which the winding unit pulls the wire into a direction different from the direction in which the polishing unit is moved. May be provided.

  Further, the polishing portion may include at least one of an inner winding brush and a needle cloth, and at least one of the brush tip of the inner winding brush and the needle tip of the needle cloth may form an inner peripheral surface of the polishing portion. Good.

  As described above, the specific configuration of the polishing member, the housing, the drive unit, and the stop mechanism of the polishing device according to one invention of the present application is not limited to a specific one. The first embodiment will be described by taking as an example a case where the member and the housing can be divided into two, a motor is used for the drive unit, and the stop mechanism uses the engagement pin to stop the rotation of the polishing member.

  In addition, as described above, the specific configuration of the polishing unit and the moving means for moving the polishing unit with respect to the object to be processed of the polishing apparatus according to another invention of the present application is not limited to a specific one. However, in the following, the case where the polishing apparatus of the present invention includes a base portion that can be divided in addition to the polishing portion, and the moving means is configured to move the polishing portion and the base portion relative to each other as an example. A second embodiment will be described. In the second embodiment, the base portion and the polishing portion each have a pair of upper and lower blocks capable of sandwiching the workpiece, a polishing member is accommodated in the pair of blocks of the polishing portion, and a pneumatic cylinder is provided as the moving means. Take the case of being used as an example.

  Furthermore, Embodiment 3 will be described by taking as an example a case where a polishing apparatus according to another invention of the present application has a winch vehicle that moves a polishing portion by pulling a wire fixed to the polishing portion as a pulling means. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[Inner volume rotating brush 110]
Furthermore, as shown in FIG. 6, a semi-inner winding brush 110a, which is one of a pair of divided pieces constituting the inner winding rotary brush 110, includes a semi-circular geared case 111 and two semi-circular inner winding brushes. 112 and one inter-brush spacer 113. Here, an engagement hole H that engages with the engagement pin 31 of the lower stop mechanism 30a or the upper stop mechanism 30b is formed on the side surface perpendicular to the rotation center of the semicircular geared case 111. In addition, an inclined groove G that guides the engagement pin 31 to the engagement hole H is formed deeper in the side surface of the semicircular geared case 111 as the engagement hole H approaches the rotation direction of the semi-inner winding rotary brush 110a. It is formed to become.

[Usage method and operation of polishing apparatus 100]
Next, the usage method and operation | movement of the polishing apparatus 100 of Embodiment 1 are demonstrated.

  FIGS. 9 and 10 are diagrams for explaining a method of using the polishing apparatus according to the first embodiment of the present invention. FIGS. 9A and 9B are directions A1 and B1 in FIG. 1, respectively. FIG. 9 (c) and FIG. 9 (d) show a state where the polishing unit 100a shown in FIG. 9 (a) and FIG. 9 (b) is opened, respectively. FIGS. 10 (a) and 10 (b) show structures when the polishing apparatus 100 is viewed from the A3 direction and the C3 direction of FIG. 3, respectively. FIGS. 10 (c) and 10 (d) The state which closed the polishing part 100a shown to a) and FIG.10 (b) is shown.

  First, the polishing apparatus 100 of the first embodiment is prepared (FIGS. 9A and 9B), and the lock lever 54 is operated to lock the upper half housing 10b of the polishing portion 100a and the lower half housing 10a. The state is released, and the polished portion 100a is opened by rotating the upper half housing 10b with respect to the lower half housing 10a in the direction indicated by the arrow X1 (FIGS. 9C and 9D).

  In a state where the driving unit 20 of the polishing apparatus 100 is stopped, the semi-inner winding rotary brushes 110a and 110b are housed and fixed in either the lower half housing 10a or the upper half housing 10b, and thus the upper half housing 10b. Is rotated, the semi-inner winding rotary brush accommodated in the upper half housing 10b and the semi-inner winding rotary brush accommodated in the lower half housing 10a are separated.

  Next, with the polished portion 100a opened, the wire rope Rw as the object to be processed is placed on the main body side lower guide piece 13a and the side plate side lower guide piece 14a of the lower half housing 10a as indicated by an arrow Z. The polishing portion 100a is closed by rotating the upper half housing 10b of the polishing portion 100a in the direction indicated by the arrow X2 with respect to the lower half housing 10a (FIGS. 10A and 10B).

  Thereafter, by operating the lock lever 54, the upper locking housing 51b of the upper half housing 10b of the polishing portion 100a is pressed against the lower locking flange 51a of the lower half housing 10a of the polishing portion 100a, and the upper half housing 10b is pressed to the lower half housing. It fixes with respect to 10a (FIG.10 (c), FIG.10 (d)).

  When the power switch (not shown) of the drive unit 20 is turned on with the polishing unit 100a closed as described above, the electromagnets 33 of the lower stop mechanism 30a and the upper stop mechanism 30b are operated. As a result, the engagement pin 31 is retracted from the brush arrangement space 11a2 against the urging force of the spring member 32, and the engagement pin 31 is pin-engaged with the semi-circular geared case 111 of the semi-inner winding rotary brushes 110a, 110b. Get out of hole H. As a result, the inner winding rotary brush 110 becomes rotatable with respect to the housing 10. Further, when the power switch of the drive unit 20 is turned on, the motor of the drive unit 20 rotates, and the rotation causes the drive gear 21 to rotate, and the pair of semicircular geared cases 111 meshing with the drive gear 21 form a pair. It rotates with the semicircular inner brush 112. That is, the inner winding brush 110 rotates.

  By moving the polishing device 100 along the wire rope Rw in a state where the inner winding rotary brush 110 is rotating in this manner, the portions of the surface of the wire rope Rw that the polishing device 100 has passed are polished sequentially. Become.

  For example, when polishing a wire rope Rw used as a guardrail, after polishing a portion between two predetermined struts of the wire rope Rw, the polishing apparatus 100 is once stopped and removed from the wire rope Rw. Is attached to the portion between the struts adjacent to the wire rope Rw, and the wire rope Rw is polished again.

  FIG. 11 is a view for explaining the operation of the lower stop mechanism 30a of the lower half housing 10a shown in FIG. 5, and FIG. 11 (a) shows that the lower stop mechanism 30a uses the inner winding rotary brush 110 as a housing. FIG. 11B shows a state in which the lower stop mechanism 30a has released the fixing of the inner winding rotary brush 110 to the housing.

  In the polishing apparatus 100, when the power source of the drive unit 20 is turned off, the electromagnet 33 is turned off in the upper stop mechanism 30 b and the lower stop mechanism 30 a, so that the engagement pin 31 is attached with a semicircular gear by the biasing force of the spring member 32. The state comes into contact with the side surface of the case 111, and the engagement pin 31 is guided by the inclined groove G and engaged with the engagement hole H as the case 111 with the semicircular gear rotates. When the engagement pin 31 engages with the engagement hole H, the semi-inner winding rotary brushes 110a and 110b are fixed to either the upper half housing 10b or the lower half housing 10a, respectively.

  For this reason, the arrangement position of the engagement pin 31 with respect to the lower half housing side plate 12a and the upper half housing side plate 12b and the position of the pin engagement hole G on the side surface of the case 111 with the semicircular gear are determined in advance. By setting the dividing surface of the inner winding rotary brush 110 to coincide with the dividing surface of the housing of the polishing device 100 when 31 is engaged with the pin engaging hole H, the inner winding rotating brush 110 is stopped. In this state, the split surface of the inner winding rotary brush 110 and the split surface of the housing of the polishing apparatus 100 can be matched. Further, in a state where the split surface of the inner winding rotary brush 110 and the split surface of the housing of the polishing apparatus 100 coincide with each other, the polishing portion 100a is opened by rotating the upper half housing 10b of the polishing portion 100a with respect to the lower half housing 10a. In this case, the semi-inner winding rotary brushes 110a and 110b that are divided pieces of the inner winding rotary brush 110 are separated together with the lower half housing 10a and the upper half housing 10b that are divided pieces of the housing 10, respectively.

  With the polishing apparatus 100 of the first embodiment having such a configuration, the following effects can be obtained.

  In this polishing apparatus 100, since the inner winding rotary brush 110 which is an annular polishing member having an inner peripheral surface for polishing the wire rope Rw is used as the polishing member, the surface of the object to be processed such as the wire rope is made uniform. Can be polished.

  In addition, since the inner winding rotary brush 110 and the housing 10 that holds the inner winding rotary brush 110 are configured to be rotatable so that the inner winding rotary brush 110 and the housing 10 can be opened, the wire rope Rw is used as the inner winding rotary brush. It is not necessary to insert the wire rope Rw into the inner winding rotary brush 110 and the housing 10 from the end of the wire rope Rw to be disposed in the housing 110 and the housing 10. Moreover, in this inner winding rotary brush 110, the inner peripheral surface of this brush is a surface that polishes the wire rope Rw, and the inner winding rotary brush 110 has a simple cylindrical structure.

  On the other hand, in the maintenance device disclosed in Patent Document 3, a plurality of rotating cylindrical brushes that rotate and revolve around the rotation center of the rotating brush assembly are disposed, and the workpiece is polished on the outer peripheral surface of each rotating cylindrical brush. Thus, the configuration of the rotating brush assembly of the maintenance device disclosed in Patent Document 3 has a complicated structure as compared with the inner winding rotating brush 110 of the present embodiment.

  Further, in this polishing apparatus 100, the stop mechanism 30 is configured such that the dividing surface of the inner winding rotary brush 110 coincides with the dividing surface of the housing 10 after the driving unit 20 stops applying the rotational driving force to the inner winding rotating brush 110. Therefore, when the polishing apparatus 100 is removed from the wire rope Rw, the inner rotary brush 110 is also detached from the wire rope Rw simply by opening the housing 10. The removal work is easy.

  In addition, since the energization of the electromagnet 33 in the stop mechanism 30 is stopped simultaneously with the stop of the power supply to the drive unit 20, each divided piece (half-inner winding rotary brush 110a, 110b) of the inner winding rotary brush 110 is a housing. It is fixed to any one of ten divided pieces (lower half housing 10a, upper half housing 10b) by an engaging pin 31. For this reason, when the housing 10 is opened, the semi-inner winding rotary brush 110a or 110b accommodated in the upper half housing 10b does not fall from the upper half housing 10b.

  Further, since the pair of semicircular inner winding brushes 112 are arranged at predetermined intervals by the inter-brush spacer 113 in the semicircular geared cases 111 of the semiinner winding rotating brushes 110a and 110b, they are semicircular. While the inner brush 112 is in use, even if the width increases like a worn toothpaste toothbrush, it is possible to prevent the adjacent semicircular inner brush 112 from getting tangled.

  In the first embodiment, a round hole is formed in the side surface of the semicircular geared case 111 as the pin engagement hole G that engages with the engagement pin 31 of the lower stop mechanism 30a and the upper stop mechanism 30b. However, the pin engagement hole G formed on the side surface of the semicircular geared case 111 may be a long hole. For example, the pin engagement hole G may be a long hole extending along the rotation direction of the inner winding rotary brush 110. In this case, the inner winding brush 110 can be rotated and moved with respect to the housing 10 within the range of the length of the long hole in a stopped state by the motor.

  In the first embodiment, the stop mechanism is configured to stop the rotation of the polishing member so that the dividing surface of the polishing member coincides with the dividing surface of the housing. However, the stop mechanism has such a configuration. It is not limited to. For example, the stop mechanism may stop the polishing member so that the dividing surface of the polishing member forms an angle within a predetermined angle range with respect to the dividing surface of the housing. Specifically, the inclination angle of the dividing surface of the polishing member with respect to the dividing surface of the housing when the rotation of the polishing member stops is determined by separating the dividing piece of the housing and opening the housing. Any angle that does not hinder the separation of the divided pieces of the polishing member accommodated may be used. For example, the angle is in the range of 0 to 25 degrees.

  Further, although not specifically described in the first embodiment, the engagement pin of the stop mechanism 30 is engaged with the inner winding rotary brush 110 in consideration of the replacement of the inner winding brush 110 accommodated in the housing 10. It is desirable to have a configuration for releasing the combined state by manual operation or the like.

And a control unit 1400.

  Hereinafter, the configuration of the polishing apparatus 1000 will be described in detail.

FIGS. 15 and 16 are plan views for explaining the polishing apparatus 1000 of the second embodiment. FIGS. 15A, 15B, and 15C are respectively A13 direction in FIG. FIG. 16 (d), FIG. 16 (e), and FIG. 16 (f) show the polishing device viewed from the D13 direction, the E13 direction, and the F13 direction of FIG. 13, respectively. Shown structure.

[Base 1100]
The base 1100 includes a pair of base blocks 1100a and 1100b for sandwiching the wire rope Rw, and a base drive unit (base opening / closing mechanism) 1130 for driving the pair of base blocks 1100a and 1100b. Here, the pair of base blocks 1100a and 1100b are pivotally connected by an open / close hinge pin 103. Rope fixing pads 104a and 104b are attached to portions of the base blocks 1100a and 1100b that are in contact with the wire rope Rw so that the wire rope Rw does not slip when the wire rope Rw is sandwiched between these blocks. Further, the base opening / closing mechanism 1130 has the base 1100 immovable when the pair of base blocks 1100a and 1100b sandwich the wire rope Rw, and the base 1100 opens when the pair of base blocks 1100a and 1100b opens the wire rope Rw. The pair of base blocks 1100a and 1100b are driven so as to be movable. The base opening / closing mechanism 1130 includes an opening / closing cylinder 131 that opens and closes the base 1100 by relatively rotating a pair of base blocks 1100a and 1100b. The main body of the open / close cylinder 131 is rotatably attached to a mounting bracket 132 fixed to a rear end portion of a lower base block (base lower block) 1100a by a cylinder mounting pin 133. The cylinder rod 134 of the open / close cylinder 131 is rotatably attached to a pair of opposed pin mounting flanges 102 formed at the rear end portion of the upper base block (base upper block) 1100b by a rod mounting pin 135.

[Polishing part 1200]
The polishing unit 1200 includes a pair of upper and lower polishing unit blocks 1200a and 1200b for polishing the wire rope Rw, and a polishing unit driving unit (a polishing unit opening / closing mechanism) 1230 for driving the pair of upper and lower polishing unit blocks 1200a and 1200b. Here, the pair of polisher blocks 1200a and 1200b are rotatably connected by an opening / closing hinge pin 203. A brush arrangement space 1201 is formed in a portion of the polishing block 1200a and 1200b facing the wire rope Rw. The brush arrangement 240 is accommodated in the brush arrangement space 1201 of the polishing block 1200a and 1200b. Is fixed in the brush arrangement space 1201 by the fixing member 250. The brush assembly 240 includes a brush housing case 211, a semicircular inner winding brush 212 and an inter-brush spacer 213 arranged in the brush housing case 211. Here, when the brush block 1200 is closed, the semicircular inner brush 212 has a semicircular inner brush 212 and an upper brush block (polishing portion) of the lower polishing block (polishing block lower) 1200a. The upper block) 1200b semicircular inner winding brush 212 only needs to form an inner winding brush having an inner peripheral surface for polishing the wire rope Rw. For example, the semicircular inner winding brush 212 includes: What is necessary is just to have a fan-shaped shape with a central angle of 180 degrees. However, depending on the structure of the semicircular inner winding brush 212, it may be desirable that the center angle of the semicircular inner winding brush 212 is greater than 180 degrees. A fan having a sector shape with a central angle larger than 180 degrees is used.

  A brief description is given below.

  As shown in FIG. 14, in the semicircular inner brush 212 having a structure in which the bristles Wb are sandwiched in the grooves of the semicircular brush holder 212 a and fixed by caulking, the wires are formed at both ends of the semicircular inner brush 212. The rope Rw may not be sufficiently polished. In the semicircular inner winding brush 212 having such a structure, the end of the semicircular inner winding brush 212 of the polishing unit lower block 1200a when viewed from the axial direction of the wire rope Rw with the polishing unit block 1200 closed. By making the portion and the end portion of the semicircular inner winding brush 212 of the polished portion upper block 1200b overlap, it is possible to prevent a portion where the polishing of the wire rope Rw is insufficient from occurring.

  Specifically, in the case of using a fan-shaped semicircular inner brush 212 having a central angle larger than 180 degrees, when the polishing portion is closed, between the polishing portion lower block 1200a and the polishing portion upper block 1200b. The semicircular inner winding brush 212 of the polishing unit lower block 1200a and the semicircular inner winding brush 212 of the polishing unit upper block 1200b are alternately arranged so that the ends of the semicircular inner winding brush 212 do not interfere with each other (see FIG. 13 and FIG. 15A), and the inter-brush spacer 213 has a central angle of 180 degrees so that a space for arranging the end of the semicircular inner brush 212 having a central angle larger than 180 degrees is formed. It has a smaller arc shape (see FIG. 14).

  In other words, when the central angle of the semicircular inner brush 212 is 180 degrees + α degrees, the central angle of the inter-brush spacer 213 is 180 degrees−β degrees (β ≧ α).

  The angle α is preferably in the range of 10 degrees to 30 degrees, for example, but is not limited to this range.

  However, by increasing the angle α, the overlap between the end of the semicircular inner brush 212 of the polished lower block 1200a and the end of the semicircular inner brush 212 of the polished upper block 1200b increases. Accordingly, the inter-brush spacer 213 is reduced, and the semicircular inner winding brush 212 supported by the inter-brush spacer 213 is likely to be distorted or deformed.

  On the other hand, when the angle α is reduced, the overlap between the end of the semicircular inner winding brush 212 of the polishing unit lower block 1200a and the end of the semicircular inner winding brush 212 of the polishing unit upper block 1200b is reduced, and the wire rope Rw There is a risk that it will not be possible to eliminate the part where the polishing of the material becomes insufficient.

  Therefore, considering these, it is desirable to set the angle α in an appropriate range suitable for each application.

  In general, the angle β is preferably equal to the angle α. However, the angle β is not limited to this, and the upper and lower blocks 1200a and 1200b of the upper and lower blocks 1200a and 1200b are closed when the polished portion is closed in consideration of an assembly error. The angle may be larger than the angle α by a predetermined angle (about 0 to 5 degrees) so that the end of the semicircular inner brush 212 and the end of the inter-brush spacer 213 do not interfere with each other.

[Usage method and operation of polishing apparatus 1000]
Next, the usage method and operation of the polishing apparatus 1000 of Embodiment 2 will be described.

  FIGS. 17 and 18 are views for explaining a method of using the polishing apparatus according to the second embodiment of the present invention. FIG. 17A shows a base and a polishing part before the polishing apparatus is mounted on a workpiece. FIG. 17 (b) shows a state in which the base portion and the polishing portion before the polishing apparatus is attached to the object to be processed are opened. FIG. 18A shows a state in which the base and the polishing unit after the polishing apparatus is attached to the object to be processed are opened, and FIG. 18B shows the base and polishing after the polishing apparatus is attached to the object to be processed. The state which closed the part is shown.

  First, the polishing apparatus 1000 according to the second embodiment is prepared (FIG. 17A), and when the operation unit 1600 is operated so that the base 1100 and the polishing unit 1200 are opened, the pressure control unit 1400 uses the compressed air from the compressor 1500 as the base. 1100 and the opening / closing cylinders 131 and 231 of the polishing unit 1200 are rotated to relatively rotate the base upper block 1100b and the base lower block 1100a of the base 1100 to open the base 1100, and the polishing lower block 1200a and the polishing of the polishing unit 1200 The upper block 1200b is rotated relatively to open the polishing unit 1200 (FIG. 17B).

  In this state, the polishing apparatus 1000 is moved in the direction of the arrow Y1 with respect to the wire rope Rw, and the wire rope Rw becomes the rope fixing pad 104a of the lower base block 1100a of the polishing apparatus 1000, as shown in FIG. And the polishing apparatus 1000 is arrange | positioned with respect to the wire rope Rw so that it may be located on the brush assembly 240 of the polish part lower block 1200a.

  In this state, when the operation unit 1600 is operated so that the base 1100 and the polishing unit 1200 are closed, the pressure control unit 1400 sends compressed air from the compressor 1500 to the open / close cylinders 131 and 231 of the base 1100 and the polishing unit 1200. The base upper block 1100b and the base lower block 1100a of the base part 1100 rotate relatively to close the base part 1100, and the polishing part lower block 1200a and the polishing part upper block 1200b of the polishing part 1200 rotate relatively to rotate the polishing part 1200. Close (FIG. 18B).

  Thereafter, the polishing apparatus 1000 automatically performs an operation of polishing the wire rope Rw.

  FIG. 19 is a diagram for explaining the operation of the polishing apparatus according to the second embodiment of the present invention, and FIGS. 19A to 19D sequentially show the operation of polishing an object to be processed by the polishing apparatus. ing.

  First, the base lower block 1100a and the base upper block 1100b strongly hold the wire rope Rw, so that the base 1100 is fixed to the wire rope Rw when the base 1100 and the polished portion 1200 are relatively moved, and the polished portion 1200 is The state moves relative to the rope Rw.

  In this state, as shown in FIGS. 19A to 19D, when the base portion 1100 and the polishing portion 1200 are relatively close to each other or away from each other, the position B0 of the base portion 1100 with respect to the wire rope Rw does not change. Therefore, the polishing unit 1200 moves back and forth between the position P0 with respect to the wire rope Rw and the position P1 with respect to the wire rope Rw, and the portion of the section D0 of the wire rope Rw is polished by the polishing unit 1200. In the figure, Ln is the distance between the base 1100 and the polished part 1200 when they are closest to each other, and Lf is the distance between the base 1100 and the polished part 1200 when they are farthest away. The length of the section D0 where the wire rope Rw is polished is Lf−Ln.

  In this way, the polishing apparatus 1000 reciprocates a predetermined number of times (for example, 3 to 5 times) set in advance according to the state of the object to be processed between the sections D0 of the wire rope Rw. Polish up.

  FIG. 20 is a view for explaining the operation of the polishing apparatus according to the second embodiment of the present invention, and FIGS. 20 (a) to 20 (c) show the operation in which the polishing apparatus is self-propelled.

  As shown in FIG. 20 (a), when the air pressure applied to the open / close cylinder 131 of the base 1100 is 0 with the base 1100 and the polished portion 1200 relatively farthest from each other, the gap between the base 1100 and the wire rope Rw However, the air pressure applied to the opening / closing cylinder 231 of the polishing unit 1200 is changed by the semicircular inner brush 212 of the lower polishing block 1200a and the semicircular inner brush 212 of the upper polishing block 1200b. The pressure is maintained to maintain the state where the rope Rw is strongly sandwiched. For this reason, in this state, when the friction resistance between the polishing portion 1200 and the wire rope Rw is larger than the friction resistance between the base portion 1100 and the wire rope Rw, the base portion 1100 and the polishing portion 1200 are relatively close to each other. As shown in 20 (b), the base 1100 moves so as to be attracted to the polishing unit 1200.

  Thereafter, when the base portion 1100 and the polishing portion 1200 are relatively closest, the friction resistance between the base portion 1100 and the wire rope Rw is applied to the air pressure applied to the opening / closing cylinder 131 of the base portion 1100. Increase to be greater than the frictional resistance between. In this state, when the base portion 1100 and the polishing portion 1200 are moved away from each other, the base portion 1100 remains fixed with respect to the wire rope Rw, and the polishing portion 1200 moves relative to the wire rope Rw. (FIG. 20 (c)). As a result, the base part 1100 moves from the position B0 to the position B1, and the polishing part 1200 reciprocates between the position P1 and the position P2 while the base part 1100 is fixed to the position B1, so that the wire rope The portion between the position P1 and the position P2 of Rw will be polished.

  As described above, the polishing apparatus 1000 according to the second embodiment includes the base 1100 and the polishing unit 1200 attached to the wire rope Rw, and the moving unit 1300 that relatively moves the base 1100 and the polishing unit 1200. The operation of moving the wire rope Rw with respect to the wire rope Rw and the operation of moving the base portion 1100 with respect to the wire rope Rw to cause the polishing apparatus 1000 to self-run, the force with which the base portion 1100 holds the wire rope Rw. Therefore, the operation of polishing the surface of the wire rope Rw and the operation of moving along the wire rope Rw can be performed by one drive unit. Further, since the semicircular inner winding brush 212 for polishing the wire rope Rw is fixed to the pair of polishing unit lower blocks 1200a and the polishing unit upper block 1200b of the polishing unit 1200, the structure for moving the semicircular inner winding brush 212 is as follows. This is unnecessary, and the structure of the polishing unit 1200 can be simple.

  In the second embodiment, the case where the base does not have the function of polishing the wire rope Rw has been described, but the base may also have the function of polishing the wire rope Rw. In this case, the wire rope Rw is polished by the base even when the polishing apparatus 1000 is self-propelled by the movement of the base with respect to the wire rope Rw. In other words, in this case, the polishing apparatus 1000 has two polishing portions. In the operation mode in which one polishing portion is fixed to the wire rope Rw and the other polishing portion is movable with respect to the wire rope Rw, the friction resistance between the one polishing portion and the wire rope Rw is set to the other polishing portion. It can implement | achieve by making it larger than the frictional resistance of wire rope Rw. Specifically, the air pressure applied to the opening / closing cylinder of the other polishing portion may be reduced to 0 while the air pressure supplied to the opening / closing cylinder of one polishing portion is kept constant.

  Further, in the second embodiment, the case where the brush assembly 240 is fixed to the polishing unit 1200 has been described. However, the brush assembly 240 is similar to the first embodiment with respect to the upper and lower blocks of the polishing unit 1200. And may be rotatable. In this case, the brush assembly 240 may be rotated by a motor, or may be rotated by the action of a force received from the wire rope Rw when the polishing unit 1200 is moved relative to the wire rope Rw.

  Further, in the second embodiment, the polishing apparatus includes two driving air cylinders 1301 and 1302 for relatively moving the base 1100 and the polishing part 1200 in the polishing part lower block 1200a. The driving air cylinder may be incorporated not only in the polishing unit lower block 1200a but also in the polishing unit upper block 1200b. In this case, it is necessary to provide a pipe connection hole for connecting a pipe for supplying and discharging air from the control unit 1400 to the drive air cylinder, similarly to the polishing unit lower block 1200a, on the upper surface of the polishing unit upper block 1200b. There is.

  Thus, the number of driving air cylinders provided in the polishing unit 1200 is not limited, and it is sufficient that at least one driving air cylinder is provided in at least one of the polishing unit lower block 1200a and the polishing unit upper block 1200b.

  In the second embodiment, the case where one wire rope Rw is polished by one polishing device 1000 has been described. For example, a plurality of wire ropes are arranged in the height direction on a guardrail used in a central separation zone of an expressway. It may be installed in parallel with. When such a plurality of wire ropes are polished by the polishing apparatus 1000, work efficiency is improved by polishing the plurality of wire ropes by connecting a plurality of stages of the polishing apparatus 1000 in the height direction.

  Such usage can be achieved, for example, by providing a flange for connecting the polishing apparatus 1000 of the second embodiment vertically in a plurality of stages.

The moving means 3200 moves the polishing unit 3100 relative to the wire rope Rw so that the wire rope Rw is polished by the inner peripheral surface of the polishing unit 3100.

  Hereinafter, the polishing unit 3100 will be described in detail first.

[Polishing part 3100]
FIG. 24 is a perspective view for explaining a specific structure of the polishing unit 3100 of the polishing apparatus shown in FIG. 23. FIG. 24 (a) shows the polishing unit 3100 in an open state, and FIG. 24 shows the inner peripheral surface of the polished upper portion 3100b, FIG. 24C shows the inner peripheral surface of the polished lower portion 3100a, and FIGS. 24D and 24E show hairs used for the polished portion 3100, respectively. An example of the structure of a long-legged cloth LNc and a bristle-short garment Snc is shown.

  The polishing unit 3100 is divided into a polishing unit upper part (a polishing unit block) 3100b and a polishing unit lower part (a polishing unit block) 3100a in the same manner as the polishing unit 1200 of the polishing apparatus 1000 of the second embodiment shown in FIG. A polishing unit driving unit (a polishing unit opening / closing mechanism) 3130 for driving the pair of polishing unit blocks 3100a and 3100b is provided.

  The pair of polisher blocks 3100a and 3100b are rotatably connected by an opening / closing hinge pin 3103. The portions facing the wire rope Rw of the polishing block 3100a and 3100b are formed with a cloth mounting space 3101a and 3101b similar to the brush arrangement space 1201 of the polishing block 1200a shown in FIG. 14, and the polishing block 3100a and 3100b. In the garment mounting spaces 3101a and 3101b, a garment holder 3111 to which a garment is attached is accommodated, and the garment holder 3111 is fixed to the polishing block 3100a and 3100b.

When the winch portion 3200b is fixed to the guide post Gp by sandwiching the guide post Gp with the post receiving portion 3234, the tip of the contact plate 3242 is configured to contact the guide post Gp. For this reason, when winch part 3200b pulls polish part 3100, it can counter the reaction which arises by pulling pull wire Pw.

  Further, the support column 3201a of the support mechanism 3201 that supports the winding unit 3210 and the projecting column 3241 of the projecting mechanism 3240 are reinforced by a reinforcing member 3205 that connects them. However, depending on the strength of the support column 3201a of the support mechanism 3201 and the extension column 3241 of the extension mechanism 3240, the reinforcing member 3205 may be omitted.

  The winch vehicle 3200 is equipped with a battery, and power from the battery is supplied to a travel motor (not shown) that drives the wheels Wr of the carriage unit 3200a and a drive motor 3206 that drives the winding unit 3210. It is configured as follows. However, winch vehicle 3200 is not limited to battery driving. The winch vehicle 3200 may be an engine-driven vehicle, for example.

  Further, in the polishing apparatus 3000 of the third embodiment, similarly to the polishing apparatus 1000 of the second embodiment, the compressed air from the compressor receives an open / close cylinder 3131 of each polishing section 3100 and an air cylinder of the fixing mechanism 3201 via the control section. 3232 is supplied. The compressor may be mounted on the winch vehicle 3200 or provided separately from the winch vehicle 3200. In addition, the winch vehicle 3200 is provided with an operation unit (not shown) for applying battery power to each motor and supplying compressed air of the compressor to each cylinder. However, the operation unit for operating the winch vehicle 3200 may be provided separately from the winch vehicle 3200.

[Usage method and operation of polishing apparatus 3000]
Next, the usage method and operation of the polishing apparatus 3000 of Embodiment 3 will be described.

  FIG. 29 and FIG. 30 are diagrams for explaining how to use and operate the polishing apparatus 3000 according to the third embodiment of the present invention. FIG. 29 shows that the polishing unit 3100 is attached to an object to be processed (a wire rope of a guardrail). And the state which fixed the winch vehicle to the post EGp of a guardrail is shown, and FIG. 30 has shown the operation | work state which polishes a to-be-processed object.

  For example, as shown in FIG. 29, the operator causes the winch vehicle 3200 to self-propell by operation of the operation unit and is disposed adjacent to the polishing post end guide post (work end post) EGp, and further, the work end post EGp. The winch vehicle 3200 is positioned so that is located between the clamp arm 3233 and the post receiving portion 3234. Thereafter, as shown in FIG. 27B, when the air cylinder 3232 of the fixing mechanism 3230 is driven by the operation of the operation unit, the lower end portion of the work end post EGp is clamped by the clamp arm 3233 and the post receiving unit 3234. . Thereby, the winch vehicle 3200 is fixed to the work end post EGp. At this time, the tip of the abutment plate 3242 of the projection mechanism 3240 of the winch vehicle 3200 comes into contact with the upper end portion of the work end post EGp, and the winch vehicle 3200 is operated by the reaction when the winch vehicle 3200 pulls the wire rope Rw. It is regulated to fall to the EGp side.

  On the other hand, the polishing portion 3100 is attached to each of the five wire ropes Rw of the guardrail so as to be positioned as close as possible to the guide post (work start post) SGp at the polishing start position.

  In this case, before attaching the polishing unit 3100 to the wire rope Rw, the compressed air from the compressor (not shown) is supplied in advance to the polishing unit opening / closing mechanism 3130 of each polishing unit 3100 by operating the operation unit. A pair of polished unit blocks 3100a and 3100b of 3100 are held in an open state. Then, the polishing portion 3100 is placed on each wire rope Rw so that the wire rope Rw is positioned between the pair of polishing portion blocks 3100a and 3100b, and in this state, the polishing portion opening / closing mechanism 3130 is driven by operating the operation portion. Then, the pair of polished portion blocks 3100a and 3100b are closed (FIG. 29). Thereby, in the polisher 3000, the tips of the upper and lower polisher blocks 3100a and 3100b are in contact with the outer peripheral surface of the wire rope Rw.

  When the drive motor 3206 is operated in this state, the rotational force of the drive motor 3206 is transmitted to the drive pulley 3206a, the rotation transmission belt 3207, the driven pulley 3208, and the take-up shaft 3211 fixed to the rotation shaft 3206. The take pulley 3212 rotates. As a result, the pull wire Pw bound to the wire hook Fw of the polishing unit 3100 is taken up by the take-up pulley 3212 and the polishing unit 3100 is pulled toward the work end post EGp. As a result, the polishing unit 3100 moves while rubbing the outer peripheral surface of the wire rope Rw on the tip of the cloth cloth mounted on the inner side, and the surface of the wire rope Rw is polished by the polishing unit 3100.

  When the polished portion 3100 is pulled by the pull wire Pw in this way, the winch vehicle 3200 is pulled from the pull wire Pw to the work start post SGp side as a reaction thereof, but the winch vehicle 3200 is moved to the work end post EGp by the fixing mechanism 3230. Since it is fixed, it does not move to the work start post SGp side due to the reaction from the pull wire Pw. In addition, the direction in which the take-up pulley 3212 pulls the pulling wire Pw is changed by the driven pulley 3222 of the direction changing portion 3220 to a direction orthogonal to the direction in which the pulling portion 3100 pulls the polishing wire 3100. The reaction when pulling the polished portion 3100 is dispersed in a direction perpendicular to the direction in which the wire rope Rw extends. For this reason, it is suppressed that the winch vehicle 3200 is pulled to the work start post SGp side.

  Further, since the direction in which the winding pulley 3212 pulls the wire rope Rw is set to a direction orthogonal to the direction in which the wire rope Rw pulls the polishing portion 3100, the winch vehicle 3200 is a wire rope that is a guard rail due to a reaction from the pulling wire Pw. Pulled in a direction approaching Rw. However, since the abutting piece 3242 of the tension mechanism 3240 is in contact with the upper end portion of the work end post EGp, even if the winch vehicle 3200 is pulled to the wire rope Rw side by the pull wire Pw, the protrusion against the work end post EGp. By the tension of the tension mechanism 3240, it is possible to prevent the winch vehicle 3200 from being pulled toward the work end post EGp or to fall down.

  In this way, the winch portion 3200b of the winch vehicle 3200 winds the pull wire Pw, so that the polishing portion 3100 attached to each of the five wire ropes Rw is located near the work start post SGp along the wire rope Rw. Move to the vicinity of the work end post EGp.

  By the way, since the polishing unit 3100 is sandwiched between the pair of polishing unit blocks 3100a and 3100b so as to wrap the wire rope Rw, the polishing unit 3100 is fixed to the work end post EGp of the wire rope Rw by a U-shaped bolt or the like. You can't pass through the part. For this reason, when the polishing unit 3100 moves to the vicinity of the work end post EGp, the drive motor 3206 is stopped, the polishing unit 3100 is once removed from the wire rope Rw, and the wire rope Rw is moved to the adjacent post portion Pa. Installing.

  As described above, in the polishing apparatus 3000 according to the third embodiment, the polishing unit 3100 is attached to the wire rope Rw and has an inner peripheral surface for polishing the wire rope Rw, and the wire rope Rw is polished by the inner peripheral surface of the polishing unit 3100. The winch vehicle 3200 that moves the polishing unit 3100 with respect to the wire rope Rw by pulling the polishing unit 3100 with the pulling wire Pw is provided, so that the wire rope Rw can be quickly moved by moving the polishing unit 3100 in one direction. Can be polished.

  In this way, when the polishing unit 3100 is moved in one direction with respect to the wire rope Rw to polish the wire rope Rw, the polishing unit 1200 is reciprocated with respect to the wire rope Rw as in the polishing apparatus 1000 of the second embodiment. However, the number of times that the polishing unit 3100 moves on the surface of the wire rope Rw is smaller than in the case of polishing, but the polished state by the polishing apparatus 3000 of the third embodiment is compared with that by the polishing apparatus 1000 of the second embodiment. It was possible to obtain a finished state that was not inferior when visually observed by a person.

  In addition, the polishing unit 3100 is configured to be separable so that the wire rope Rw is introduced into the space surrounded by the inner peripheral surface, so that the wire rope Rw of the wire rope Rw used for the guard rail is By sandwiching from the side, the polished portion 3100 can be mounted such that its inner peripheral surface is in close contact with the outer peripheral surface of the wire rope Rw.

  In the winch vehicle 3200, the take-up pulley 3212 pulls the pull wire Pw in a direction orthogonal to the direction in which the pull wire Pw pulls the polished portion 3100. Therefore, the winch vehicle 3200 has a guard rail due to a reaction from the pull wire Pw. However, since the abutment piece 3242 of the projection mechanism 3240 is in contact with the upper end portion of the work end post EGp, the winch vehicle 3200 is pulled toward the work end post EGp or falls down. There is no.

  Further, in the polishing portion 3100, a soft garment LNc with long bristles is arranged on the front side in the moving direction with respect to the short bristles and hard garments SNc. When polishing with, you can effectively drop fine rust without increasing resistance.

It will be fixed with respect to Gp. Further, the means for pulling the polishing part 3100 is not limited to the winch part (winch), and the polishing part 3100 attached to the object to be processed such as the wire rope Rw is used to polish the object to be processed. Any device can be used as long as the polishing unit 3100 can be moved relative to the workpiece by pulling.

  In the third embodiment, as the polishing device 3000, the winding unit 3000 converts the direction in which the winding unit pulls the pulling wire Pw into a direction orthogonal to the moving direction of the polishing unit 3100. The direction in which the take-up portion pulls the pulling wire Pw may be inclined by a direction changing portion in a direction other than the direction perpendicular to the moving direction of the polishing portion 3100. Further, the polishing device 3000 has a winding portion that is a polishing portion 3100. The pulling wire Pw may be pulled in a direction coinciding with the moving direction.
