Description

  The present invention relates to a cable holding device that can hold a heavy cable such as a power cable and prevent the cable from falling.

  The configuration of a conventional cable holding device is disclosed in Patent Document 1. 12 is a front view of the cable holding device 50, FIG. 13 is a side view of the cable holding device 50, and FIG. 14 is a plan view of the cable holding device 50.

  In the conventional cable holding device 50, as shown in FIGS. 12 to 14, a pair of (left and right in FIG. 12) a pair of shackles 62, a pair of chain bars 63, and the like from one suspension hook 61. A suspension rod 51 is suspended.

  Then, in the upper and lower pivot pins P1 provided on each suspension rod 51, the vicinity of the outer vertex of the upper and lower triangular link pieces 54 is pivotally supported, and the vertex below the inner short side of the upper and lower triangular link pieces 54 In the vicinity, a substantially U-shaped frame body 52 is pivotally supported in plan view via upper and lower pivot pins P2.

  The pair of frame main bodies 52 (left and right in FIG. 12) supported by the pair of hanging rods 51 in this way have two pivot pins 55 (front and rear in FIG. By being inserted into the through hole of the piece 52b, it is connected like a bowl. By pulling out one connecting pin 55 and using the other connecting pin 55 as a rotation shaft, the pair of frame main bodies 52 can be opened.

  A pair of rubber pad holding members 53a are pivotally supported via upper and lower pivot pins P3 near the apex above the inner short side of the upper and lower triangular link pieces 54. The pair of rubber pads 53 held by the pair of rubber pad holding members 53a grips the cable.

  When a cable is set in the cable holding device 50 or when a cable is removed from the cable holding device 50, one of the connecting pins 55 is pulled out, and the pair of frame main bodies 52, that is, the pair of rubber pads 53, around the other connecting pin 55. Is released. With the cable holding device 50 holding the cable, the one connecting pin 55 that has been removed is returned to the through hole of the corresponding pivot piece 52b, and the pair of frame main bodies 52 are connected in a bowl shape again.

  When the cable held by the cable holding device 50 is cut at a position above the cable holding device 50 due to an accident or the like, the cable tends to drop due to gravity. At this time, the pair of rubber pads 53 holding the cable also tends to fall together with the cable due to the frictional force acting between the cables. In response to this action, the rubber pad holding member 53a tries to turn around the pivot pin P3 in the direction in which the rubber pad holding member 53a falls, and in conjunction with this turning operation, the upper and lower triangular link pieces 54 are connected. However, the rubber pad holding member 53a tends to rotate around the upper and lower pivot pins P1. And since these rotation operation acts so that the space | interval of a pair of rubber pad 53 may be narrowed, as a result, the force with which a pair of rubber pad 53 hold | maintains a cable increases instantaneously, and the fall of a cable is prevented effectively. The

  The above-described cable holding device 50 can effectively prevent the cable from dropping when the cable is cut. However, the cable holding force for preventing the fall depends on the rotation operation around the pivot pin P3 of the rubber pad holding member 53a and the rotation operation around the pivot pin P1 of the triangular link piece 54. That is, the cable holding force for preventing the cable from dropping is the distance D1 (cable thickness and cable holding distance) from the contact surface between the rubber pad 53 and the cable to the axis of the pivot pin P3 in the gripped state before the cable is dropped. The angle A (cable of the cable) that a straight line perpendicular to both axes from the axis of the pivot pin P3 toward the axis of the pivot pin P1 forms the contact surface between the rubber pad 53 and the cable. The thickness and the size of the cable holding device 50), the distance D2 between the axis of the pivot pin P3 and the axis of the pivot pin P1 (which may depend on the size of the cable holding device 50), etc. Is done.

  For this reason, in order to ensure that the cable holding force for preventing the drop is sufficient, it is necessary to prepare cable holding devices 50 of different sizes according to the thickness of the target cable.

  Further, in the above-described cable holding device 50, since the movable members (the hanging rod 51, the frame main body 52, the triangular link piece 54, the rubber pad 53) are exposed, there is a risk that the operator may be caught in the hand or the like. is there.

  Further, in the state where the cable holding device 50 is suspended by the suspension hook 61, the pivot piece 52b of the frame body 52 is relatively easy to move. Therefore, the operation of removing the connecting pin 55 from the pivot piece 52b, The operation of returning the connecting pin 55 to the pivot piece 52b is not easy and requires skill.

  The present invention has been created based on the above findings. An object of the present invention is to ensure that the cable holding force for preventing the fall is sufficient and constant regardless of the thickness of the cable, and as a result, a cable that can cope with a wide range of cable thicknesses. It is to provide a holding device. Another object of the present invention is to provide a cable holding device capable of reducing the degree of exposure of a movable member and reducing the danger of an operator. Furthermore, the objective of this invention is providing the cable holding device which can implement the attachment or detachment operation | work of a cable easily.

  The present invention provides a left portion and a right portion that provide a pair of inclined surfaces that are arranged to face each other so that a separation distance on the lower side is reduced, a back portion to which the left portion and the right portion are fixed, and the pair of pairs A pair of movable bodies arranged to face each other on an inclined surface, and a pair of elastic bodies arranged to face each other on the opposed surfaces of the pair of movable bodies, the pair of movable bodies, The cable holding device is connected through a synchronous link so as to be simultaneously movable in the same direction and at the same speed on a pair of inclined surfaces.

  According to the present invention, the cable can be reliably gripped by the pair of elastic bodies arranged to face each other on the opposed surfaces of the pair of movable bodies that can move on the pair of inclined surfaces. In particular, since the pair of elastic bodies that grip the cable simultaneously move in the same direction and at the same speed due to the synchronization link, the cable drop prevention function can be made to function more stably.

  And when the cable held by the cable holding device of the present invention is cut at an upper part than the cable holding device due to the occurrence of an accident or the like, the cable tries to drop by gravity, The pair of elastic bodies holding the cable also tries to fall together with the cable due to the frictional force acting between the cable. In response to this action, the pair of moving bodies that hold the pair of elastic bodies attempt to move downward on the pair of inclined surfaces. And since this movement operation acts so that the space | interval of a pair of elastic body may be narrowed, as a result, the force with which a pair of elastic body hold | maintains a cable increases instantaneously, and the fall of a cable is prevented effectively.

  The cable holding force for preventing the fall is greatly influenced by the grip state before the cable is dropped (for example, the distance between the opposing surfaces of the elastic body, that is, the distance between the contact surfaces of the elastic body and the cable). There is no. Therefore, regardless of the thickness of the cable, it is possible to guarantee that the cable holding force for preventing the fall is sufficient, and as a result, it is possible to cope with a wide range of cable thickness (the upper limit of the cable thickness). Is defined by the separation distance between the pair of inclined surfaces).

  In addition, according to the present invention, there are fewer movable members (mainly only a movable body and an elastic body) compared to the conventional cable holding device 50, and these movable members are covered by the left, right and back portions. Therefore, the danger to the operator can be reduced.

  An opening / closing mechanism that covers movable members (mainly moving bodies and elastic bodies) on the front side of the left and right portions to further reduce the danger of the operator and / or prevent undesired disconnection of the set cable. Is preferably provided.

  In this case, the opening / closing mechanism further includes a buckle member with a lock function that is rotatably provided on one of the left part and the right part, and an arm hook provided on the other of the left part and the right part. And a U-shaped arm member rotatably provided on the buckle member. The arm member rotates the buckle member and the arm member when the lock function of the buckle member is released. It is preferable that the arm hook member is attached to and detached from the arm hook member while being moved, and is fixed to the arm hook member when the lock function of the buckle member is activated.

  When such an aspect is adopted, the opening / closing operation of the opening / closing mechanism is extremely simple and safe. In particular, when compared with the opening / closing operation of the frame main body 52 via the connecting pin 55 in the conventional cable holding device 50, the improvement in workability is extremely remarkable.

  In the present invention, the pair of inclined surfaces disposed so as to face each other so that the lower separation distance is reduced are visually recognized in a substantially V shape in a side view. In the present invention, it is preferable that each of the pair of moving bodies has two or more rollers that are spaced apart in the vertical direction and roll on each of the pair of inclined surfaces.

  As described above, when the moving body moves on the inclined surface by rolling of two or more rollers separated in the vertical direction, the moving body can move on the inclined surface very stably. The rollers may be cylindrical rollers that are long in the front-rear direction, or a pair may be provided on each of the front and rear sides (in the latter case, the total number of suitable rollers is four or more). Moreover, it is preferable that a rail groove or the like is provided in a track region where the roller rolls on the inclined surface.

  Each of the pair of moving bodies is provided with a locking member that rotates via a rotation pin, and the locking member is provided above each of the left part and the right part. It is preferable that a locked portion that can be locked is provided.

  When such an aspect is adopted, for example, the moving body is manually lifted upward (the interval between the elastic bodies is widened), and the locking member is locked with the locked portion, thereby moving the moving body to the upper position. Can be temporarily fixed. In this state (in a state where the distance between the elastic bodies is widened), setting the cable between the elastic bodies or conversely removing the cable from between the elastic bodies can be carried out very easily.

  Furthermore, by sharing the rotation pin that rotates the locking member with the shaft that rotatably supports the above-described roller, an increase in the number of components can be suppressed.

  Moreover, it is preferable that an upper part of each of the left part and the right part is provided with an unlocking drive part that operates to release the locking of the locking member with respect to the locked part. .

  When such an aspect is adopted, the locking member can be automatically unlocked with respect to the locked portion by operating the locking release driving unit. This makes it possible for the locking release driving unit to function as a safety device during operations such as setting a cable between elastic bodies and removing a cable from between elastic bodies.

  Specifically, for example, the locking release drive unit has a solenoid switch. In this case, the locking of the locking member with respect to the locked portion can be released instantaneously and can function as an extremely effective safety device.

  Moreover, it is preferable that the handle is provided in the upper part of the said back part.

  In the cable holding device of the present invention, the back portion is a rigid body that fixes the left portion and the right portion, and there are fewer movable members than the conventional cable holding device 50 (mainly only the moving body and the elastic body). It can be easily transported by using a handle provided on the.

  According to the present invention, the cable can be reliably gripped by the pair of elastic bodies arranged to face each other on the opposed surfaces of the pair of movable bodies that can move on the pair of inclined surfaces. And when the cable held by the cable holding device of the present invention is cut at an upper part than the cable holding device due to the occurrence of an accident or the like, the cable tries to drop by gravity, The pair of elastic bodies holding the cable also tries to fall together with the cable due to the frictional force acting between the cable. In response to this action, the pair of moving bodies that hold the pair of elastic bodies attempt to move downward on the pair of inclined surfaces. And since this movement operation acts so that the space | interval of a pair of elastic body may be narrowed, as a result, the force with which a pair of elastic body hold | maintains a cable increases instantaneously, and the fall of a cable is prevented effectively. The cable holding force for preventing the drop is not greatly affected by the grip state before the cable is dropped. Therefore, regardless of the thickness of the cable, it is possible to ensure that the cable holding force for preventing the drop is sufficient, and as a result, it is possible to deal with a wide range of cable thicknesses.

[Set the cable to the cable holding device 1]
Next, the operation of the first embodiment will be described.

  With reference to FIG. 3, first, the right end side of the buckle member 21 is separated from the roller protection wall 12b in a state where the lock lever 23 is pulled and the lock function of the buckle member 21 is released. Along with this, the engagement between the U-shaped arm member 24 and the arm hook member 27 is released. Then, the front side of the cable holding device 1 is opened by rotating the U-shaped arm member 24 to the right and retracting it.

  Next, referring to FIG. 5, the locking members 18 a and 18 b provided on each of the pair of moving bodies 15 a and 15 b are manually pulled up as hand lifters. Along with this, the pair of moving bodies 15a and 15b is raised along the pair of inclined surfaces S by the rolling of the roller 15r, and the interval between the pair of elastic bodies 16a and 16b is widened.

  The pair of locking members 18a and 18b are further rotated outward via a pivot shaft 15s as a rotation pin, and the locked portions 19a and 19b at the upper part of each of the left part 11a and the right part 11b. Locked to 19b. Along with this, a state in which the distance between the pair of elastic bodies 16a and 16b is widened is maintained.

  The cable holding device 1 in such a state is hung near the cable C to be held using the hooks 32a and 32b. Then, the position is adjusted so that the cable C to be held is disposed between the pair of elastic bodies 16a and 16b.

  When it is confirmed that the cable C is positioned between the pair of elastic bodies 16a and 16b, the engagement between the locking members 18a and 18b and the locked portions 19a and 19b is released, and the locking member 18a and 18b are slowly lowered manually using the weights of the locking members 18a and 18b and the moving bodies 15a and 15b. And a pair of elastic bodies 16a and 16b contact | abut to the cable C of a holding | maintenance object (refer FIG.6 and FIG.7).

  Thereafter, referring to FIG. 3 again, the U-shaped arm member 24 is rotated leftward, and then the buckle member 21 is rotated rightward, whereby the U-shaped arm member 24 is moved to the arm hook. Engage with member 27. Thereby, the front side of the cable holding device 1 is closed.

  The operation of detaching the cable C from the cable holding device 1 can also be carried out in accordance with substantially the same procedure as described above.

[Cable fall prevention function by cable holding device 1]
When the cable C held by the cable holding device 1 is cut at a position above the cable holding device 1 due to an accident or the like, the cable C tends to fall due to gravity. At this time, the pair of elastic bodies 16a and 16b holding the cable C also tends to fall together with the cable C due to the frictional force acting between the cable C.

  In response to this action, the pair of moving bodies 15a and 15b holding the pair of elastic bodies 16a and 16b tends to move downward on the pair of inclined surfaces S, respectively. And since this movement operation acts so that the space | interval of a pair of elastic bodies 16a and 16b may be narrowed, as a result, the force with which a pair of elastic bodies 16a and 16b hold | maintain the cable C increases, and the fall of the cable C is carried out. Is effectively prevented.

  The cable holding force for preventing the drop is the gripping state before the cable C is dropped (for example, the distance between the opposing surfaces of the elastic bodies 16a and 16b, that is, between the contact surfaces of the elastic bodies 16a and 16b and the cable C). It is not greatly affected by distance.

  Therefore, regardless of the thickness of the cable C, it is possible to ensure that the cable holding force for preventing the fall is sufficient, and as a result, it is possible to deal with a wide range of cable thicknesses.

  The maximum value of the thickness of the cable C that can be held is defined to be approximately 90 mm or less (for example, φ85), which is the minimum separation distance between the pair of inclined surfaces S. On the other hand, the minimum thickness of the cable C that can be held depends on the shape of the opposing surfaces of the pair of opposing elastic bodies 16a and 16b, but is slightly recessed at the center as shown in FIG. In some cases, it is about φ15.

[Summary of effects of cable holding device 1]
As described above, according to the cable holding device 1 of the first embodiment, a pair of elastic bodies disposed opposite to each other on the opposing surfaces of the pair of moving bodies 15a and 15b that can move on the pair of inclined surfaces S, respectively. The cable C can be reliably gripped by 16a and 16b.

  When the cable C held by the cable holding device 1 of the first embodiment is cut due to an accident or the like, the cable C tends to fall due to gravity. At this time, the cable C is gripped. The pair of elastic bodies 16a and 16b that have been used also try to fall together with the cable C due to the frictional force acting between the cables. In response to this action, the pair of moving bodies 15a and 15b holding the pair of elastic bodies 16a and 16b tends to move downward on the pair of inclined surfaces S, respectively. And since this movement operation acts so that the space | interval of a pair of elastic bodies 16a and 16b may be narrowed, as a result, the force with which a pair of elastic bodies 16a and 16b hold | maintain the cable C increases, and the fall of the cable C is carried out. Is effectively prevented.

  The cable holding force for preventing the drop is the gripping state before the cable C is dropped (for example, the distance between the opposing surfaces of the elastic bodies 16a and 16b, that is, between the contact surfaces of the elastic bodies 16a and 16b and the cable C). It is not greatly affected by distance. Therefore, regardless of the thickness of the cable C, it is possible to ensure that the cable holding force for preventing the fall is sufficient, and as a result, it is possible to deal with a wide range of cable thicknesses.

  Further, according to the cable holding device 1 of the first embodiment, there are fewer movable members (mainly the moving bodies 15a and 15b and the elastic bodies 16a and 16b) compared to the conventional cable holding device 50, and the movable members Since it is covered with the left part 11a, the right part 11b, and the back part 13, a worker's danger can be reduced.

  In addition, since the opening / closing mechanism 20 that covers the movable member is provided on the front side of the left part 11a and the right part 11b, the danger of the operator is further reduced, and the undesired disconnection of the set cable C is more reliably prevented. Is done.

  In addition, the opening / closing mechanism 20 of the first embodiment includes a buckle member 21 with a lock function that is rotatably provided in the right part 11b (one example of the left part and the right part), and a left part 11a (the left part and the right part). An arm hook member 27 provided on the other example of the right side) and a U-shaped arm member 24 rotatably provided on the buckle member 21, and the arm member 24 is a buckle member. The buckle member 21 and the arm member 24 can be attached to and detached from the arm hook member 27 when the lock function 21 is released, while the buckle member 21 is fixed to the arm hook member 27 when the lock function is activated. It has become. For this reason, the opening / closing operation of the opening / closing mechanism 20 is extremely simple and safe. In particular, when compared with the opening / closing operation of the frame main body 52 via the connecting pin 55 in the conventional cable holding device 50, the improvement in workability is extremely remarkable.

  In addition, each of the pair of moving bodies 15a and 15b of the first embodiment moves on the inclined surface S by two sets of rollers separated in the vertical direction by one set before and after rolling on each of the pair of inclined surfaces S. Moving. Thereby, the movement on the inclined surface S of the moving bodies 15a and 15b is made extremely smoothly and stably.

  In addition, the pair of moving bodies 15a and 15b of the first embodiment are connected via the synchronization link 17 so as to be simultaneously movable on the pair of inclined surfaces S in the same direction at the same speed.

  In addition, hooks 132a and 132b are provided above the left part 111a and the right part 111b via shackles 131a and 131b, respectively.

[Set the cable to the cable holding device 101]
Next, the operation of the second embodiment will be described. The operation of the second embodiment is substantially the same as the operation of the first embodiment except for the safety device function described later.

  Similar to the opening / closing mechanism 20 described above with reference to FIG. 3, first, the lock lever 123 is pulled to release the lock function of the buckle member 121, and the right end side of the buckle member 121 is separated from the roller protective wall 112b. It is. Along with this, the engagement between the U-shaped arm member 124 and the arm hook member 127 is released. Thereafter, the U-shaped arm member 124 is rotated to the right and retracted, whereby the front side of the cable holding device 101 is opened.

  Next, the locking members 118a and 118b provided on each of the pair of moving bodies 115a and 115b are manually pulled up as hand lifters. Accordingly, the pair of moving bodies 115a and 115b is raised along the pair of inclined surfaces S by the rolling of the roller 115r, and the interval between the pair of elastic bodies 116a and 116b is widened.

  The pair of locking members 118a and 118b is further rotated outward via a pivot shaft 115s as a rotation pin, and the locked portions (19a) at the upper part of each of the left part 111a and the right part 111b. , 19b). Along with this, a state in which the distance between the pair of elastic bodies 116a and 116b is widened is maintained.

  The cable holding device 101 in such a state is hung near the cable C to be held using the hooks 132a and 132b. Then, the position is adjusted so that the cable C to be held is disposed between the pair of elastic bodies 116a and 116b.

  When it is confirmed that the cable C is positioned between the pair of elastic bodies 116a and 116b, the engagement between the locking members 118a and 118b and the locked portions (19a and 19b) is released, and the engagement The stop members 118a and 118b are slowly lowered manually using the weights of the locking members 118a and 118b and the moving bodies 115a and 115b. Then, the pair of elastic bodies 116a and 116b abut against the cable C to be held (see FIG. 11; however, unlike FIG. 11, the pusher members 142a and 142b remain in the contracted state).

  Thereafter, the U-shaped arm member 124 is rotated to the left and then the buckle member 121 is rotated to the right, whereby the U-shaped arm member 124 is engaged with the arm hook member 127. Thereby, the front side of the cable holding device 101 is closed.

  The operation of detaching the cable C from the cable holding device 101 can also be carried out in accordance with generally the same procedure as described above.

[Cable holding function by cable holding device 101 (fall prevention function)]
Similar to the cable holding device 1, when the cable C held by the cable holding device 101 is cut at a position above the cable holding device 101 due to an accident or the like, the cable C tends to drop due to gravity. . At this time, the pair of elastic bodies 116 a and 116 b holding the cable C also tends to fall together with the cable C due to the frictional force acting on the cable C.

  In response to this action, the pair of moving bodies 115a and 115b holding the pair of elastic bodies 116a and 116b attempt to move downward on the pair of inclined surfaces S, respectively. This moving operation acts to narrow the distance between the pair of elastic bodies 116a and 116b. As a result, the force that the pair of elastic bodies 116a and 116b holds the cable C increases instantaneously, and the cable C falls. Is effectively prevented.

  The cable holding force for preventing the drop is a gripping state before the cable C is dropped (for example, the distance between the opposing surfaces of the elastic bodies 116a and 116b, that is, between the contact surfaces of the elastic bodies 116a and 116b and the cable C). It is not greatly affected by distance.

  Therefore, regardless of the thickness of the cable C, it is possible to ensure that the cable holding force for preventing the fall is sufficient, and as a result, it is possible to deal with a wide range of cable thicknesses.

  The maximum value of the thickness of the cable C that can be held is defined to be approximately 90 mm or less (for example, φ85), which is the minimum distance between the pair of inclined surfaces S. On the other hand, the minimum value of the thickness of the cable C that can be held depends on the shape of the opposed surfaces of the pair of opposed elastic bodies 116a and 116b, but has a slightly recessed center (see FIG. 3). ) Is about φ15.

[Safety device function by cable holding device 101]
In 2nd Embodiment, the latching of the latching members 118a and 118b with respect to a to-be-latched part (19a, 19b) can be automatically cancelled | released by operating a latch release drive part. This makes it possible for the locking release drive section to function as a safety device during the operation of setting the cable C between the elastic bodies 116a and 116b or removing the cable C from between the elastic bodies 116a and 116b.

  In particular, since the unlocking drive unit of the present embodiment is configured by pusher members 142a and 142b that are expanded and contracted by solenoid switches 141a and 141b that can be switched instantaneously, the locking members 118a and 118b with respect to the locked parts. Can be released instantaneously and can function as an extremely effective safety device.

  For example, while the cable C to be held is dropped from the upper floor to the lower floor and the position of the cable C is being adjusted between the pair of elastic bodies 116a, 116b, If an undesired defect occurs, the drop speed becomes uncontrollable and can be extremely dangerous.

  According to the present embodiment, when a malfunction of the dropping device for the cable C is detected, or when it is detected that the dropping speed of the cable C exceeds a predetermined value, the solenoid switches 141a and 141b are instantaneously set immediately after that. By switching (cutting off the internal current), the locking members 118a and 118b can be instantaneously released, and the cable C can be held instantaneously by using the pair of elastic bodies 116a and 116b. it can.

  Signal transmission from various sensors or controllers to the solenoid switches 141a and 141b is preferably performed by wireless communication. However, at the time of the filing of the present application, an aspect by wired communication is not excluded.

  In addition, when the distance to which the cable C to be held is dropped is long, it is common to use a plurality of cable holding devices 101 according to the weight of the cable C. For example, one cable holding device 101 can be used for every three floors. In such a case, it is necessary for the safety device functions of the plurality of cable holding devices 101 to operate simultaneously. That is, it is necessary to reliably transmit signals from various sensors or controllers to the solenoid switches 141a and 141b of the plurality of cable holding devices 101.

  Therefore, in addition to the solenoid switches 141a and 141b, or in place of the solenoid switches 141a and 141b, a wire mechanism that interlocks the pusher members 142a and 142b or the locking members 118a and 118b of the plurality of cable holding devices 101 is adopted. May be.

  Note that the cable holding device 101 may be used only for use as a safety device. That is, when the cable C is dropped from the upper floor to the lower floor, the cable holding device 101 is provided so as to correspond to the laying position (track) of the cable C, and the dropping speed of the cable C cannot be controlled. After the desired dropping (laying) of the cable C is completed, the cable holding device 101 does not hold the cable C. A usage mode in which the cable holding device 101 is removed (the cable C remains as it is) can also be adopted.

[Summary of effects of cable holding device 101]
As described above, even with the cable holding device 101 of the second embodiment, the pair of elastic bodies 116a disposed opposite to each other on the facing surfaces of the pair of moving bodies 115a and 115b that can move on the pair of inclined surfaces S, respectively. 116b, the cable C can be securely held.

  When the cable C held by the cable holding device 101 of the second embodiment is cut due to an accident or the like, the cable C tends to fall due to gravity. At this time, the cable C is gripped. The pair of elastic bodies 116a and 116b that have been used also try to fall together with the cable C due to the frictional force acting between the cables. In response to this action, the pair of moving bodies 115a and 115b holding the pair of elastic bodies 116a and 116b attempt to move downward on the pair of inclined surfaces S, respectively. This moving operation acts to narrow the distance between the pair of elastic bodies 116a and 116b. As a result, the force that the pair of elastic bodies 116a and 116b holds the cable C increases instantaneously, and the cable C falls. Is effectively prevented.

  The cable holding force for preventing the drop is a gripping state before the cable C is dropped (for example, the distance between the opposing surfaces of the elastic bodies 116a and 116b, that is, between the contact surfaces of the elastic bodies 116a and 116b and the cable C). It is not greatly affected by distance. Therefore, regardless of the thickness of the cable C, it is possible to ensure that the cable holding force for preventing the fall is sufficient, and as a result, it is possible to deal with a wide range of cable thicknesses.

  Further, the cable holding device 101 of the second embodiment also has fewer movable members (mainly moving bodies 115a and 115b and elastic bodies 116a and 116b) than the conventional cable holding device 50, and these movable members are left. Since it is covered with the part 111a, the right part 111b, and the back part 113, a worker's danger can be reduced.

  In addition, since the opening / closing mechanism 120 that covers the movable member is provided on the front side of the left part 111a and the right part 111b, the danger of the operator is further reduced, and the undesired disconnection of the set cable C is more reliably prevented. Is done.

  Further, the opening / closing mechanism 120 of the second embodiment includes a buckle member 121 with a lock function that is rotatably provided on the right part 111b (one example of the left part and the right part), and a left part 111a (the left part and the right part). An arm hook member 127 provided on the other example of the right side) and a U-shaped arm member 124 rotatably provided on the buckle member 121. The arm member 124 is a buckle member. The buckle member 121 and the arm member 124 can be attached to and detached from the arm hook member 127 when the lock function 121 is released, while the buckle member 121 is fixed to the arm hook member 127 when the lock function is activated. It has become. For this reason, the opening / closing operation of the opening / closing mechanism 120 is extremely simple and safe. In particular, when compared with the opening / closing operation of the frame main body 52 via the connecting pin 55 in the conventional cable holding device 50, the improvement in workability is extremely remarkable.

  In addition, each of the pair of moving bodies 115a and 115b of the second embodiment is arranged on the inclined surface S by two sets of rollers separated in the vertical direction by one set before and after rolling on each of the pair of inclined surfaces S. Moving. Thereby, the movement on the inclined surface S of the moving bodies 115a and 115b is made extremely smoothly and stably.

  In addition, the pair of moving bodies 115a and 115b of the second embodiment are connected via the synchronization link (17) so that they can move simultaneously on the pair of inclined surfaces S in the same direction at the same speed. Thereby, since a pair of elastic body 116a, 116b holding the cable C is simultaneously moved at the same speed in the same direction, the fall prevention effect of the cable C can be functioned more stably.

  Further, each of the pair of moving bodies 115a and 115b of the second embodiment is provided with locking members 118a and 118b that rotate via a pivot shaft 115s, and each of the left part 111a and the right part 111b. In the upper part of the, there are provided locked portions (19a, 19b) to which the locking members 118a, 118b can be locked. Therefore, the locking members 118a and 118b and the moving bodies 115a and 115b are manually lifted upward to widen the space between the elastic bodies 116a and 116b, and the locking members 118a and 118b are moved to the locked portions (19a and 19b). , The moving bodies 115a and 115b can be temporarily fixed at the upper position. In this state (with the gap between the elastic bodies 116a and 116b widened), it is very easy to set a cable between the elastic bodies 116a and 116b, or conversely remove the cable from between the elastic bodies 116a and 116b. It is.

  Furthermore, in the second embodiment, an increase in the number of parts is suppressed by sharing the pivot pin that pivots the locking members 118a and 118b with the pivot shaft 115s that rotatably supports the roller 115r. ing.

  Also in the cable holding device 101 of the second embodiment, the back surface portion 113 is a rigid body that fixes the left portion 111a and the right portion 111b, and has fewer movable members than the conventional cable holding device 50 (mainly a moving body). 115a and 115b and the elastic bodies 116a and 116b), the handle 113h provided on the back surface portion 113 can be used for easy conveyance.

  And in 2nd Embodiment, the latching of the latching members 118a and 118b with respect to a to-be-latched part (19a, 19b) can be automatically cancelled | released by operating a latch release drive part. This makes it possible for the locking release drive unit to function as a safety device during the operation of setting the cable C between the elastic bodies 116a and 116b or removing the cable C from between the elastic bodies 116a and 116b.

  In particular, since the unlocking drive unit of the second embodiment is configured by pusher members 142a and 142b that are expanded and contracted by solenoid switches 141a and 141b that can be instantaneously switched, The lock of 118b can be released instantaneously and can function as an extremely effective safety device.

  Therefore, the cable holding device 101 of the second embodiment can be used only for the purpose as a safety device. For example, when the cable C is dropped from the upper floor to the lower floor, the cable holding device 101 is provided so as to correspond to the laying position (track) of the cable C, and the dropping speed of the cable C cannot be controlled. After the desired dropping (laying) of the cable C is completed, the cable holding device 101 is not allowed to hold the cable C. A use mode in which the cable holding device 101 is removed can also be adopted.
