JP5511002B2 - Clamping aid for tip of operation rod - Google Patents

Description

  The present invention relates to a versatile clamping aid that can clamp various portable tools and the like without using a dedicated adapter for each tool.

  In consideration of safety, the indirect hot wire method is recommended for work on high-voltage distribution lines, and various special tools are attached to the tip of the insulation operation rod. However, if various operations are to be performed by the indirect hot wire method, a dedicated tip tool (with an adapter) is required for each tool. For example, in the case of a wrench or the like, a dedicated tool attached to the tip of an insulating operation rod is used. Even in a driver or the like, various operations are performed by using a dedicated tool.

When carrying out such an indirect hot wire construction method, make sure that the operator carries a set of indirect hot wire tools (insulated Yatco, tongs, common operation rod and tip tools) to the relevant work site. However, there is no problem if the vehicle on which these tools can be loaded can get close to the work site, but if the worker is to work in the mountains or islands, the worker will share the necessary tools and materials. It must be transported by. Also, in the event of an emergency in the event of a large-scale disaster, the indirect hot line tools deployed at each office will be insufficient, so work (direct hot line method) should be carried out wearing high-pressure rubber gloves. I have to.
For this reason, if a versatile adapter that can be shared by various tools can be used instead of attaching each tool individually using a dedicated adapter, the number of transport tools can be reduced, and even if there is a shortage of dedicated adapters, It is desirable because it can perform hot wire work. For this reason, conventionally, there has been proposed a grip assisting tool for attaching an operation rod tip shown in Patent Documents 1 and 2.

  The grip assisting tool shown in Patent Document 1 is an assisting tool attached to the distal end of an insulating operation rod, a main body member having a joint portion at the base end, a rotating grip attached to the upper end side of the main body member, A slider that slides up and down by rotation of the rotating grip and moves the clamping member on the front end side toward and away from each other, and approaches a side surface of a tool or the like inserted into the opening on the upper part of the main body member by rotation of the rotating grip It is made to clamp by the pinching member of the front-end | tip.

  Further, the grip assisting tool shown in Patent Document 2 is an assisting tool that is attached to the distal end of an insulating operation rod, and includes a main body member having a joint portion at the base end, and an interior pipe that is mounted in the upper opening of the main body member. And an adjustment band wound around the main body member. The belt portion of the adjustment band enters the slit that opens in the circumferential direction of the main body member, and is inserted into the upper opening of the inner pipe by tightening the inner pipe. The side of the tool is tightened and fixed.

It is a figure which shows a state.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 to 3, the clamping aid 1 is used by being attached to a distal end portion of an operation rod 25 described later, and a tubular member 2 attached to the distal end portion of the operation rod 25 and the tubular member. A pair of clampings that are provided on the distal end side of 2 to form a clamping space 5 for inserting a gripping part for tools, and to allow the gripping part for tools to be clamped while adjusting the size of the clamping space 5 It has a member 3 (3a, 4b) and a pair of clamping adjustment members 4 (4a, 4b) provided between the pair of clamping members.

  The tubular member 2 is made of a hard member such as metal, and includes a joint portion 18 on the base end side of which a distal end of an insulating operation rod 25 described below is detachably mounted. The joint portion 18 has a bottomed cylindrical insertion portion 20 whose base end is open so that the distal end portion 26 of the operation rod 25 can be inserted, and a T-shape is formed on the opposing circumferential surface of the insertion portion 20. The engaging groove 21 is formed.

  The operation rod 25 is known per se and is configured to have an insulating function. The side wall of the tip portion 26 is provided with a pin 27 protruding radially at a position shifted by 180 ° phase. A pin 28 that is displaced in the axial direction protrudes from the upper surface of the tip. The pin 28 is pressed by a built-in spring (not shown) and normally protrudes.

  Therefore, when the cylindrical member 2 is attached to the distal end portion of the operating rod 25, the distal end portion 26 of the operating rod 25 is inserted into the inserted portion 20 of the cylindrical member 2 and the pin 27 is inserted into the engaging groove 21. In this manner, the joint portion 18 of the cylindrical member 2 is attached to the distal end portion 26 of the operation rod 25. Thereafter, the cylindrical member 2 is pressed in the axial direction, the pin 28 of the operation rod 25 is sunk against the elastic force of the built-in spring, and the cylindrical member is rotated in this state to cause the pin 27 to engage with the engaging groove 21. After that, the axial force of the cylindrical member 2 is released, and the cylindrical member is returned to the axial direction by the urging force of the pin 28, whereby the pins 27 and 27 are engaged with the engaging groove 21. It is engaged so that it cannot be detached.

  A pair of mounting pieces 2a and 2b are extended at the upper end of the cylindrical member 2, and a shaft 6 on which a pair of clamping members 3 described below is rotatably locked is attached to the pair of mounting pieces 2a and 2b. It is supported.

  The pair of sandwiching members 3 (3a, 3b) are each composed of a hard member such as a metal having an arc cross section, and are disposed to face each other with their recesses facing each other. A holding space 5 for inserting the holding portion is formed, and both side edges of one holding member 3a are opposed to both side edges of the other holding member 3b. On both side edges of each clamping member 3, a recess (not shown) for receiving the shaft 6 is formed at a aligned position, and connecting margins 7 (7a, 7b) projecting outward are formed at aligned positions. Yes.

  A through hole is formed in the coupling allowance 7a formed in one clamping member 3a, and a screw hole in which a female screw is formed is formed in the coupling allowance 7b formed in the other clamping member 3b. A pair of clamping members 3 is assembled by assembling a pair of clamping members 3 so that the shaft 6 is sandwiched between the recesses, inserting the screw 8 through the through hole of one connection allowance 7a, and screwing it into the screw hole of the other connection allowance 7b. The members 3a and 3b are engaged with the shaft 6 so as to be rotatable, and are connected so as to be able to come into and out of contact with each other by adjusting the screwing amount of the screw 8. This screw 8 constitutes an interval adjusting means, and the distance between the holding members, that is, the size of the holding space 5 can be changed by moving the screw 8 back and forth.

  In this example, the pair of sandwiching members 3 (3a, 3b) extends from a state where the cylindrical member 2 is erected in the axial direction shown in FIG. 2 (a) to a state where it is tilted as shown in FIG. 2 (b). The shaft 6 can be rotated about 90 ° around the shaft 6, and the movement in the rotational direction is restricted so as not to rotate in each of the state where the clamping member 3 is raised and tilted. A stopper 9 is provided on the cylindrical member 2. The stopper 9 is constituted by, for example, a pin that protrudes inward so as to be able to advance and retreat with respect to the side surface of the cylindrical member 2, and the pin is moved outward when the clamping member 3 is rotated to minimize or eliminate the protrusion inward. When the rotation is restricted, the pin protrudes inward, and the peripheral surface of the pin is brought into contact with the bottom surface or the outer peripheral surface of the holding member 3 to prevent the rotation.

  Further, a clamping adjusting member 4 (4a, 4b) made of a hard member such as metal is attached via a screw 10 at substantially the center inside each clamping member 3a, 3b. That is, the clamping adjusting member 4 is loosely fitted to the tip of the screw 10 that is screwed to the clamping member 3 so as to be able to advance and retract and protrudes into the clamping space 5. It is formed and arranged so as to face each other so that the recesses face each other.

Each screw 10 is attached so as to be screwed back and forth on a line connecting the center of the holding space 5 and a portion of the holding member 3 to which the screw 10 is attached. The protruding amount of the holding adjusting member 4 by the screw 10. A protrusion amount adjusting means for adjusting the angle is configured. Therefore, the interval between the clamping adjustment members 4 is changed by moving the screw 10 back and forth.
In the above-described example, the anti-slip material 11 made of an elastic member such as rubber is attached to the inner surfaces of the respective holding members 3a and 3b.

  Therefore, when attaching the tools to the clamping aid 1, first, the size of the clamping space 5 is adjusted by screwing back and forth the screw 8 in anticipation of the size of the gripping portion of the tools to be installed. A similar gripping portion is inserted into the clamping space 5 from the distal end side (opening end) of the clamping member 3. Thereafter, the screw 8 is turned to reduce the distance between the holding members 3a and 3b, so that the gripping portion of the tool is pinched directly or indirectly via the pinching adjustment member 4 by the pair of holding members 3 in the process. The fixing position of the gripping portion in the holding space 5 is determined, and the gripping portion is primarily fixed (temporarily fixed). Next, the screw 10 is turned to adjust the protruding amount of each of the holding adjustment members 4a and 4b, and the holding adjustment member 4 is strongly pressed against the side surface of the holding portion, and the holding portion is moved by the pair of holding adjustment members 4a and 4b. It is only necessary to firmly clamp from both sides.

  In FIG. 4 to FIG. 6, specific usage examples using the above-described clamping assisting tool 1 are shown. Hereinafter, this will be described. First, in FIGS. 4 and 5, an example is shown in which a driver 30 as a portable tool in which the grip portion 31 is cylindrical is mounted.

  In this way, when the grip portion 31 is formed in a columnar shape, the screw 8 is turned to expand the holding space 5 larger than the size of the grip portion 31, and the protruding amount of the holding adjustment member 4 is reduced. In this state, the grip portion 31 of the driver 30 is inserted into the clamping space 5 from the tip (open end) of the clamping member 3. After that, the screw 8 is turned to narrow the interval between the clamping members 3a and 3b. Since the grip portion 31 of the driver 30 has a cylindrical shape, it often comes into contact with the holding adjustment member 4 before coming into contact with the inner surface of the holding member 3 via the anti-slip material 11, and the interval between the holding members 3 is reduced. As a result, the clamping force of the clamping member 3 acts on the gripping part 31 via the clamping adjustment member 4, and the fixing position of the gripping part 31 in the clamping space 5 is determined, and this gripping part is primarily fixed ( Temporarily fixed). Next, the screw 10 is turned to adjust the amount of protrusion of each of the holding adjustment members 4 a and 4 b, the holding adjustment member 4 is strongly pressed against the side surface of the inserted holding part 31, and the holding part 31 is moved by the holding adjustment member 4. The attachment is complete when firmly clamped from both sides.

Therefore, by adjusting the interval between the holding members 3a and 3b with the screws 8 provided on the holding member 3, the position of the holding part 31 in the holding space 5 is determined and fixed primarily, and in this state, the holding part 31 is strongly clamped from both sides by the clamping adjustment members 4a and 4b, so that the grip portion 31 of the driver 30 is circular in cross section, but is securely fixed by the clamping adjustment members 4a and 4b.
Such attachment is the same in the case where another tool having a cylindrical grip portion, for example, a portable high / low voltage detector is attached instead of the driver 30.

  FIG. 6 shows an example in which an electric utility knife 32 as a portable tool is mounted. Unlike the driver 30, the grip portion 33 of the electric knife 32 is formed in a substantially rectangular cross section having flat portions 33a on both sides. In the tools having such a gripping portion 33, the clamping space 5 is expanded to be larger than the thickness width of the gripping portion 33 and the protruding amount of the clamping adjustment member 4 is reduced, and the flat portion 33 a is clamped in this state. It accommodates in the clamping space 5 so that it may become substantially parallel to the mating surface of the member 3, and turns the screw | thread 8 and narrows the space | interval of clamping member 3a, 3b. Then, if the gripping portion 33 has a small shape, the gripping adjustment member 4 may come into contact with the gripping adjustment member 4 first. However, if the gripping portion 33 has a large shape, the corners of the gripping portion 33 may contact the inner surface of the gripping member 3. If the gap between the holding members 3a and 3b is reduced by contacting with the slip stopper 11 and the holding member 33 is held by the holding members 3a and 3b, the position in the holding space 5 is fixed and fixed primarily. .

In this state, since the flat portion 33a of the grip portion 33 is not pressed, the electric knife 32 is easily tilted when a force is applied to the electric knife 32 from a direction orthogonal to the flat portion 33a. Then, after that, the screw 10 is turned to increase the protruding amount of each of the holding adjustment members 4a and 4b, and the flat portion 33a of the gripping portion 33 is firmly held from both sides by the paired holding adjustment members 4a and 4b. For this reason, even if it is the holding part 33 which has the flat part 33a, a reliable and firm clamping state is obtained.
Such attachment is the same when attaching other tools having a flat portion in the gripping portion, such as a monkey spanner, to the clamping aid 1 instead of the electric knife 32.

  FIG. 7 shows a second embodiment of the present invention. In this example, the sandwiching assisting tool 1 includes a sandwiching member 3 and a sandwiching adjustment member 4 on a cylindrical member 2 having a joint portion 18 on the base end side. The cylindrical member 2, the pair of sandwiching members 3 a and 3 b, and the pair of sandwiching adjustment members 4 a and 4 b are integrated with each other at the opening end of the tubular member 2. It is comprised with the cap 41 attached.

  The cylindrical member 2 has a cylindrical shape with an open tip, and a screw groove 42 for screwing the cap 41 is engraved on the outer peripheral surface on the tip side over a predetermined width in the axial direction. A joint portion 18 for detachably mounting the tip portion 26 of the insulating operation rod 25 is formed. Further, the peripheral wall of the cylindrical member 2 is provided with an interference prevention groove (interference prevention groove 36a for avoiding interference with the screw 8 and interference with the screw 10) for avoiding interference with the screws 8 and 10 of the clamping unit 40 described below. An interference prevention groove 36b) to be avoided extends from the opening end in the axial direction.

  In the clamping unit 40, a pair of clamping members 3 (3a, 3b) having a circular arc cross section are arranged to face each other with their concave portions facing each other, and a clamping adjustment is made such that a pair of circular arc sections is formed between the pair of clamping members. The members 4 (4a, 4b) are arranged to face each other with their recesses facing each other.

  Each clamping member 3a, 3b has both side edges of one clamping member opposed to both side edges of the other clamping member, and the coupling margins 7 (7a, 7a, 7b) projecting outward from both side edges of each clamping member 3 7b) is formed at the aligned position. A through hole is formed in the coupling allowance 7a formed in one clamping member 3a, and a screw hole in which a female screw is formed is formed in the coupling allowance 7b formed in the other clamping member 3b. Is inserted through the through hole of one connection allowance 7a and screwed into the screw hole of the other connection allowance 7b, and the pair of sandwiching members 3 are connected to each other by adjusting the screwing amount of the screw. Yes. The screw 8 constitutes an interval adjusting means, and the distance between the holding members 3a and 3b, that is, the size of the holding space 5 can be changed by moving the screw 8 back and forth.

In addition, the respective clamping adjustment members 4a and 4b are attached via screws 10 at substantially the center inside the respective clamping members 3a and 3b. That is, the clamping adjustment member 4 is loosely fitted to the tip of a screw 10 that is screwed to the clamping member 3 so as to be able to advance and retract, and protrudes into the clamping space 5, and the center of the clamping space 5 and the screw 10 are attached. It is attached so that it can be screwed back and forth on the line connecting with the part.
The screw 10 constitutes a protruding amount adjusting means for adjusting the protruding amount of the holding adjustment member 4. Therefore, the interval between the holding adjusting members 4 is changed by moving the screw 10 forward and backward.
Although not shown, a slip stopper made of an elastic member such as rubber may be attached to the inner surfaces of the clamping members 3a and 3b.

The cap 41 is formed with an opening 43 for inserting a gripping portion of tools on the top plate 41a, and a screw groove 44 is formed on the inner peripheral surface, and a screw groove 42 formed on the tubular member 2 and It is designed to be screwed together. The cap 41 prevents the holding unit 40 housed in the cylindrical member 2 from falling off and fixes the holding unit 40 in the cylindrical member 2.
In addition, since the other part is the same as that of the said structural example, the same code | symbol is attached | subjected to the same location and description is abbreviate | omitted.

Therefore, when using such a clamping aid 1, the clamping unit 40 is inserted into the cylindrical member 2 with the positions of the screws 8 and 10 aligned with the positions of the interference preventing grooves 36a and 36b, and the cylindrical member 2 is inserted. The cap 41 is screwed into the upper end opening 2 of the No. 2 so that the screws 8 and 10 are exposed to the outside from the interference preventing grooves 36a and 36b, and the holding unit 40 is accommodated and held in the cylindrical member 2. In this state, the screw 8 is screwed back and forth to adjust the distance between the holding members 3 in anticipation of the size of the gripping portion of the tool to be attached, and the size of the holding space 5 is adjusted. Thereafter, the gripping portion of the tools is inserted into the holding space 5 from the tip (open end) of the cylindrical member 2. Then, by turning the screw 8 to reduce the distance between the holding members 3a and 3b, the gripping portion of the tool is pinched directly or indirectly via the pinching adjustment member 4 by the pair of holding members 3 in the process. The fixing position of the gripping portion in the holding space 5 is determined, and the gripping portion is primarily fixed (temporarily fixed).
After that, the screw 10 is turned to adjust the protruding amount of the clamping adjustment members 4a and 4b, the gripping part is strongly pressed from both sides by the clamping adjustment member 4, and the gripping part is firmly clamped and fixed by the pair of clamping adjustment members. do it.
If the cylindrical member 2 is attached to the distal end portion 26 of the operation rod 25, an indirect operation can be performed. Alternatively, the cylindrical member 2 may be first attached to the distal end portion 26 of the operation rod 25, and the gripping portion of the tool to be attached thereon may be sandwiched by the sandwiching unit 40.

Accordingly, even in such a configuration, it is possible to obtain the same operational effects as the above-described embodiment by the clamping unit 40 accommodated in the tubular member 2, and the gripping portions of various tools can be made to have the sizes and shapes. They can be firmly held together, and it is possible to prevent the tools from being displaced or dropped.
Moreover, according to such a structure, since the structure of the clamping assistance tool 1 can be simplified and it becomes possible to integrate the function which clamps the holding part of tools on the cylindrical member 2, clamping assistance tool 1 can be formed compactly, and handling becomes easy.

In the above-described configuration, the clamping adjustment member 4 is a member having an arcuate cross section, and the means for adjusting the projection amount of the clamping adjustment member 4 (projection amount adjustment means) is constituted by the screw 10 that advances and retracts to the clamping member 3. However, as shown in FIG. 3B , the screw 10 constituting the protrusion amount adjusting means may be used as the clamping adjusting member 4.

  In the first and second embodiments described above, an example in which the means for adjusting the interval between the pair of holding members 3 and the means for adjusting the protruding amount of the holding adjustment member 4 are configured by screws 8 and 10. Although shown, instead of this, a one-touch type fastener as shown in FIG. 8 may be used.

  In this example, instead of the screw 8, an arm 50 pivotally mounted in the vicinity of the coupling allowance 7a (7b) of one clamping member 3a (3b), and the middle and the other clamping of the arm 50 The connecting member 51 pivotally attached to the vicinity of the connecting allowance 7b (7a) of the member 3b (3a) constitutes a distance adjusting means so that the arm 50 is along the side surface of the holding member 3a (3b). When tilted, the distance between the clamping members 3a and 3b is reduced, and when the arm 50 is raised substantially perpendicular to the side surface of the clamping member 3a (3b), the distance between the clamping members 3a and 3b is increased. ing.

  Further, instead of the screw 10, a rod 52 extending from the clamping adjustment member 4 (4 a, 4 b) and penetrating the side surface of the clamping member 3 and projecting outward is provided at the projecting end of the rod 52. A compression spring 53 interposed between the saliva portion 52a and the outer surface of the clamping member 3 and a hinge pin 55 installed on a mounting piece 54 projecting from the outer surface of the clamping member 3 are rotatably attached. The clamp lever 56 constitutes a protrusion amount adjusting means. The head portion 56a of the clamp lever 56 is always in contact with the saliva portion 52a urged outward by the urging force of the compression spring 53, and the distance from the outer peripheral curved hinge pin 55 of the head portion 56a is set. When the clamp lever 56 is raised continuously substantially vertically with respect to the side surface of the clamping member 3, the distance from the hinge pin 55 to the contact portion with the saliva portion 52 a is reduced. Is set so that the distance from the hinge pin 55 to the contact portion with the saliva portion 52a becomes larger as the angle is tilted along the side surface of the clamping member 3. Therefore, when the clamp lever 56 is raised substantially perpendicular to the clamping member 3, the amount of protrusion of the clamping adjustment member 4 (4a, 4b) from the clamping member 3 (3a, 3b) becomes small, and the clamping lever 56 is When tilted along the side surface of the clamping member 3, the amount of protrusion of the clamping adjustment member 4 (4a, 4b) from the clamping member 3 (3a, 3b) is increased.

  Therefore, by using such a configuration, after inserting the gripping portion 60 of the tool into the clamping space 5, the arm 50 is tilted to narrow the interval of the clamping space 5, and the gripping portion 60 is primarily fixed. By tilting the clamp lever 56 and pressing the clamping adjustment member 4 strongly against the gripping part 60, the gripping part 60 can be firmly clamped by the pair of clamping adjustment members 4, and each operation can be performed with one touch. Can be improved.
