Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a binding device such as a can body, and more specifically, a rope is hung on the side surface of an assembly formed by sequentially abutting the bundled objects to attach the rope. The present invention relates to a device for bundling these objects to be bound in a column by tightening.

[Conventional technology]

FIG. 3 and FIG. 4 show, as one application target of the present invention, a mine field processing device as disclosed in, for example, Japanese Patent Laid-Open No. 62-213699.

This minefield processing device 1 stores a large number of explosive blocks 10 in a shell 3 of a rocket 2, and deploys these explosive blocks on a minefield to perform an explosion treatment for a buried mine. Reference numeral 4 is a rocket motor fixed to the shell 3, 5 and 6 are front and rear lids of the shell, respectively, and 7 is a parachute folded and housed in the rear lid.

As shown in FIG. 4, each explosive block 10 is mainly constituted by loading a thick cylindrical can body 11 with an explosive 12, and the explosive blocks are connected in series via a connecting means 13. A rope anchoring device 14 is arranged on the front side of the foremost explosive block 10.
The device 14 has an annular base body 15 and a latch 16 projecting outward from a position where the outer periphery of the base body is divided into four equal parts, and each latch 16 is a pin.
It is pivotally supported by 17 so that it can be tilted rearward, and a disk 19 is engaged with a claw 18 that extends forward from its inner end to restrain the tilting. Disk 19 and explosive block at the front
10 and 10 are connected by a connection measure 20. A spring case 21 is arranged on the rear side of the last explosive block 10, and these are connected by a connecting means 22. A coil spring 23 is mounted in the spring case. Then, the base body 15 of the rope anchoring device 14, the can body 11 of each explosion block 10, and the periphery of each end of the spring case 21 are sequentially abutted to form an aggregate 24 of the bundled bodies 14, 10 and 21. The body is bound by a binding device 25 adjacent to the rear end of the spring case 21.

The bundling device 25 includes a cylindrical base member 28 having front and rear wall plates 26, 27, four pull balds 29 inserted through these wall plates, and hooks 30 protruding from each pull bolt. Then, the wall plate 26 and the spring case 21 are connected by a connecting means 31, and the coil spring 23 is inserted into the spring case, and then the wire rope 32 is hooked on each hook 30 and each hook 16, and each pull bolt 29. When the nuts are hooked at the rear end of the coil 33 and the nuts 33 are screwed in, the base member 28 is butted against the spring case 21 while compressing the coil spring 23, and when the nuts are further screwed in, the wire rope 32 is tightened. As a result, the aggregate 24 is bound.

After bundling the aggregates 24 together in this way, the disc 19 is connected to the frontal skull 5 (FIG. 3) via the connecting means 34, and the hanging cord 8 of the parachute 7 is connected to the base member 28.
The structure is bound and housed in the shell 3, and the rear lid 6 is fastened to the shell by a separation nut 9 or the like.

Such a mine field processing device 1 cuts off the separation nut 9 and removes the rear lid 6 when a predetermined time has elapsed after the mine field processing device 1 was launched from the ground. Then, the parachute 7 is released and the umbrella is opened, and braking is applied to the bundle 24, which is bound, from behind. As a result, the aggregate is pulled out of the shell 3 at once, and immediately after that, the foremost connecting means 34 is extended to pull out the disc 19. Therefore, since the restraint of the latch 16 is released and the wire rope 32 is loosened, the binding device 25 is thrown backward by the coil spring 23. In the process, each wire rope 32 tilts the latch 16 and simultaneously separates from them. To do.

When the binding is released in this way, the aggregates such as the explosive blocks and the like temporarily hold the aggregate posture in the air, and then the front end is pulled from the rocket 2 side and the rear end is braked from the parachute 7. Therefore, the aggregate is sequentially separated from the front and the rear, and is developed in the shape of a string while being connected to each of the connecting measures, and is dropped onto the minefield while maintaining this expanded posture.

FIG. 5 shows a binding device proposed separately by the inventors of the present invention for use in a mine field processing device. This binding device 35
The base member 36 has a disk-shaped base plate 37 and a flange 38 formed on the peripheral portion thereof, a groove 39 is formed at four equal positions of this flange, and a boss 40 is provided at the central portion so as to project. is there. Further, the binding device has two turn buckles 43 having a screw rod 41 and a screw sleeve 42 screwed to the screw rod 41, and these turn buckles are arranged in a cross shape and are inserted into the boss 40. Then, the base member 36 is butted against the spring case 21 of the assembly 24, the wire ropes 33 from the latch 16 are connected to the turn buckles one by one through the grooves 39, and the screw rod 41 and the screw sleeve 42 are connected.
The assembly 24 is bound by applying a spanner to and and tightening each pair of wire ropes. The bundling device 35 can be made flat so that the shell 3 can be shortened.

[Problems to be solved by the invention]

By the way, in such a conventional binding device, there is a problem that it takes a lot of time and effort to evenly tighten the ropes stretched over the aggregate.

For example, in the binding device 25 shown in FIG. 4, a plurality of ropes are tightened one by one, so that the work efficiency of the rope itself is inferior. In this process, the tightening force is adjusted thoroughly while checking the tension of each rope. In the bundling device 35 of FIG. 5, the tightening force is balanced between each pair of ropes, but the base member interferes and the spanner is rotated only about half a turn. Because it cannot be operated, the work speed of tightening and adjustment becomes extremely low.

In the minefield processing device, if the tightening force of each rope is uneven, the collective posture is distorted when pulling out the collective at a stretch as described above, and the two collide with the shell, or the timing of separation from the latch As a result, the temporary gathering posture in the air collapses and the subsequent unfolding posture is disturbed. Therefore, equalization of the tightening force is extremely important. In addition, due to laws and regulations related to the transportation of explosives, especially in the case of using a large number of explosive blocks, these must be assembled and bound locally, so improvement of workability is strongly desired. Of.

Therefore, the problem of the present invention is to make the tying rope more even,
And there is a point to be able to tighten efficiently.

[Means for solving problems]

Means of the present invention for solving this problem is a device for binding a bundle in a longitudinal direction of a side surface of a bundle formed by sequentially abutting the bundled bodies, and tightening the rope to bundle the bundle. A base member disposed adjacent to the rear end of the assembly, and a rear end surface of the base member having a central portion parallel to the end surface of the base member with a boss provided at the central portion of the base member. And a screw rod that is rotatably supported and has a mounting portion for a rotary tool formed at an end thereof, and a right-hand threaded portion and a left-handed threaded portion are formed at outer positions of the boss, and the screw portions of the screw rod. Respectively, and a pair of sliders provided so as to move toward or away from each other with respect to the center of the base member according to the rotation of the screw rod, and an end of the base member on each slider. An equalizer that is rotatably supported on an axis perpendicular to the surface, and is arranged on both sides of the screw rod along the hanging position of the rope so that the equalizer is rotatable about an axis perpendicular to the end surface of the base member. A pair of side sheaves are provided to support the equalizer, and the rope is oriented from the equalizer to both sides and wound around the corresponding pair of side sheaves and then hung on the side surface of the aggregate. It is characterized by having done.

[Action]

 This means works as follows.

When the screw rod is rotationally driven, the sliders screwed into the right and left threaded portions of the slider engage and slide with the base member and are symmetrically moved toward or away from each other with the equalizer. Therefore, when the screw rod is driven to rotate to one side and the two equalizers are separated from each other, the ropes oriented from the equalizers to the opposite sides and wound around the opposite side sheaves are V-shaped with the equalizer at the top. While being bent, it is pulled between the pair of side sheaves and becomes tense. At this time, the degree of tension is balanced by the equalizer, and if there is a difference in the tension between the rope portions, the pair of sliders slide together through the screw rod until the difference disappears. As a result, the rope hung on the side surface of the aggregate is uniformly tightened.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

The binding device of this embodiment is also used for a mine field processing device and is adjacent to the rear end face of an assembly 24 formed by abutting the bound objects such as the explosive block 10, the rope fastening device 14 and the spring case 21 of FIG. It is to bind the aggregate.

The base member 50 abutting on the assembly 24 is a circular base plate 51, a flange 52 extending rearward from the peripheral edge of the base plate, and a hollow boss 53 fastened to the center of the base plate 51 and protruding rearward. Is formed into a flat disk shape, and a groove 54 (FIG. 2) for rope hooking is cut in the front-rear direction at each of four positions on the outer periphery of the flange 52.

Reference numerals A-A and BB attached to FIG. 2 are base members.
The diameter of the rear surface of the base plate 51 on the bisector of one of the orthogonal surfaces AA and BB which is an orthogonal surface including the central axis O of the 50 toward the center of each of the grooves 54, 54. The line XX is set, and the diameter line YY is set further behind the line XX. In the drawing, these diameter lines are oriented in the up-down direction, and hereinafter, the relation of up, down, left and right will be referred to as the diameter line.

As shown in FIG. 1, the flange 52 is provided with holding holes 55, 55 and the boss 53 is provided with a screw hole 5 with the diameter line XX as the center.
6, 56 are respectively formed, the guide rods 57 are inserted from the respective holding holes 55, the screw portions 58 at the inner ends thereof are fastened to the screw holes 56, and the outer ends of the rods 57 are made by the holding holes 55. Hold it. Further, centering on the diameter line Y-Y, the flange 52 has tool insertion holes 59, 59, and the boss 53 has support holes 60, 59.
60 are formed respectively, and the intermediate portion of the screw rod 61 is slidably supported by the support holes 60, 60. The screw rod 61 has a right-hand threaded portion 62 and a left-handed threaded portion 63, and square heads 64, 64 for engaging the rotary tool T are formed at both ends thereof.

A pair of sliders 65 and 66 are slippers of the same shape.
67, these slippers are vertically symmetrically arranged to be slidably fitted on the guide rod 57, and a flat sliding surface 68 is formed on the front side thereof to engage with the base plate 51. . Further, a slipper 67 is fitted onto the slime rod 61 with a relatively large clearance, and a pin 69 is provided in a protruding manner at the rear of this fitted portion. Further, the sliders 65 and 66 have nuts 71 and 72 screwed into the right-hand threaded portion 62 and the left-handed threaded portion 63 of the screw rod 61, respectively, and inside these nuts, as shown in FIG. Forming a fork. Then, the nuts 71 and 72 are arranged at equal distances from the central axis O of the base member 51 to hold the screw rod fitting portion of the slipper 67 by the fork, and the holding portion is hinge bolt 7
3,73 is connected so that it can swing back and forth.

A center sheave 75 as an equalizer is supported on the pin 69 of each slipper 67, and a set screw 76 is used to prevent the slip.

On the other hand, a pair of upper and lower posts 77, 77 from the base plate 51 at left and right and up and down symmetrical portions of the central axis O.
The side sheave 78 is supported on the shaft formed at the rear end of each post, and the set screw 79 prevents the side sheave from coming off.
These side sheaves are arranged at the same distance from the base plate 51 together with the center sheaves 75, 75, and the pitch circle of each side sheave (the circle made by the center line of the rope when the rope is wound around the sheave) is orthogonal to the above. Surface A-A, B
The protruding length of each post 77 and the above-mentioned protruding portion are determined so as to be almost in contact with -B. A connecting plate 80 is fixed to the rear portions of the posts 77, 77 facing each other in the vertical direction to connect these posts to each other.

Before and after the boss 53, hooks 81 for connecting the connecting means 31 and the parachute suspension string 8 are fastened.

In the above configuration, the middle portions of the pair of upper and lower wire ropes 82 are engaged with the outside of the upper and lower center sheaves 75 so as to be oriented on both sides and form a pair of left and right side sheaves 7.
After being wound around 8,78, they are hung on the side surface of the assembly 24 through the grooves 54, 54, respectively, and their front ends are hooked 16 (Fig. 4).
Engage. Here, when the rotary tool T is engaged with the square head 64 of the screw rod 61 and rotated as shown by the arrow,
The lower sliders 65 and 66 move away from each other, and the center sheaves 75 and 75 are accompanied by this, and the middle portion of the wire rope 82 is hung from between the side sheaves 78 and 78 in a V shape to tension it. If the left and right tensions differ in this process, the center sheave 75 rotates to balance those tensions, and if the upper and lower tensions differ, the screw rod 61 slides in the support hole 60 to balance them. Let Therefore, the four wire ropes hung on the side surfaces of the aggregate 24 are evenly tightened to bind the aggregates evenly.

During this time, the slider slipper 67 is slightly tilted due to the rear end pin 69 being pulled inward, but a relatively large play is formed in the fitting portion of the screw rod 61 as described above. Moreover, since the nuts 71 and 72 are connected by the hinge bolts 73 so that they can swing,
Even if the slipper tilts, the screw rod 61 is not bent, so that the equilibrium action by sliding with the support hole 60 can be smoothly performed. And again, each one above and below
The pair of posts 77 and 77 are respectively raised by the above tension,
Although they receive a downward bending force, the vertically opposing posts are connected via the connecting plate 80, so that the bending forces cancel each other out. As a result, even if the base member 50 is formed to be thin and lightweight, a large tightening force can be applied to each wire rope, so that the aggregate can be more firmly bound.

〔effect〕

As described above, according to the present invention, it is possible to quickly and evenly tighten the bundling rope that has been hung on the assembly by rotating and driving one screw rod.
Therefore, if the present invention is applied to, for example, the explosive block assembly of the mine field processing device, the explosive block assembly can be quickly bound and the intended deployed posture can be easily reproduced.
