[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire rope for lifting a wire rope for towing a test vehicle to a skater mounted on a guide rail having flange portions at both ends of an upper surface opening as rail portions. The present invention relates to a lifting device (hereinafter, referred to as a “lifting device”) and a method of clamping a wire rope to a skater using the lifting device.

[0002]

2. Description of the Related Art As shown in FIG. 12, a vehicle collision test apparatus is used to move a test vehicle T such as an automobile in a self-propelled state to a collision wall 5.
1 is to collide with or contact with No. 1 to test the damage situation. In the vehicle collision test apparatus, the test vehicle T is guided by two skaters S, 53 mounted on the guide rail G so as to travel straight, and is towed by the wire rope W ′. Then, the test vehicle T
When the speed reaches a predetermined speed, each of the skaters S, 53
Wire 5 for clamping test vehicle T and test vehicle T
4, 55 are separated by strikers 56, 57,
The test vehicle T is caused to collide with the collision wall 51 in a self-propelled state.
The tow wire rope W ′ clamped to the front skater S is connected to another striker (not shown) after the connecting wires 54 and 55 clamping the skaters S and 53 and the test vehicle T are cut off. Is separated by
Each skater S, 53 collides with the braking stop device 58 and is stopped. When the next crash test is performed, each skater S,
53 is returned from the collision point to the running start position of the test vehicle T, and the wire rope W 'is clamped again by the skater S on the front side. This operation is performed by lifting the wire rope W ′ housed below the skater S inside the guide rail G and clamping it to the skater S. In FIG. 12, reference numeral 59 denotes a rear skater, and reference numeral 60 denotes a brake skater.

The traveling distance of the test vehicle T is about 100 m
Therefore, the wire rope W ′ is supported by a plurality of sheaves (not shown) provided at regular intervals, and the wire rope W ′ between the sheaves is in a normal state (when the test vehicle T is towed). (When the vehicle is not running), the vehicle hangs down due to the suspension force F ₁ (see FIG. 8). Operator, the wire rope W ', the work lifting against its suspension force F _1, is extremely labor intensive. For this reason, as shown in, for example, Japanese Utility Model Registration No. 2600835, a lifting device for lifting a wire rope W 'is known.

The lifting device disclosed in this publication is provided with a fulcrum at one end in the longitudinal direction of the lifting device main body, an operating portion at the other end, and a rope support at a position close to the fulcrum. Part is provided. By supporting the fulcrum on the upper surface of the guide rail and lifting the operating part, the wire rope supported by the rope support is boosted by the principle of leverage, and a force smaller than the suspension force of the wire rope. To make it liftable. However, this lifting tool cannot maintain the lifting state of the wire rope unless the operator holds a state in which the operation unit side is greatly lifted. That is, when performing a clamping operation using the lifting device, two operators, a person who operates the lifting device and a person who draws the lifted wire rope into the clamp portion of the skater and clamps it, are required. .

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention enables a lifting device to be locked and fixed to a guide rail by the suspension force of a wire rope, thereby clamping the wire rope to a skater. The task is to be able to do it alone.

[0006]

According to the present invention, there is provided a wire rope for pulling a test vehicle to a skater mounted on a guide rail having flange portions at both ends of an upper surface opening as rail portions. A wire supporting member for supporting the wire rope at one end of the lifting device main body with a fulcrum at a middle portion in a longitudinal direction of the lifting device main body. On the other end side, a locking member that is locked to the back side of the rail portion is rotatably provided, and around a fulcrum portion supported on the upper surface side of the rail portion, the lifting device main body is By pushing down the side of the locking member and lifting the wire rope supported by the rope support, the locking member inserted into the guide rail from the upper surface opening is rotated, By locking the rear surface side of the Lumpur portion, it is characterized in that to allow holding the state lifting wire rope.

Further, there is provided a method for clamping a wire rope to a skater mounted on a guide rail by using the above-mentioned pair of wire rope lifting tools. It is characterized in that the rope lifting devices are arranged facing each other, and each lifting device lifts a portion of the wire rope that intersects the skater substantially in parallel with the guide rail.

[0008] A fulcrum provided at an intermediate portion in the longitudinal direction of the lifting tool main body is supported on the upper surface side of the rail portion of the guide rail, and a wire rope is mounted and supported on a rope support portion provided on one end thereof. I do. In this state, the lifting member body is pushed down on the side of the locking member. When the locking member is rotated through approximately 90 ° with the locking member inserted into the inside of the guide rail through the upper opening, and the pressing force is released, the lifting device main body is locked and fixed to the guide rail. Thus, the lifting state of the wire rope supported by the rope support is maintained.

That is, the fulcrum portion presses the upper surface of the rail portion downward by the suspension force of the wire rope acting on the rope support portion of the lifting tool body, and the locking member pushes the back surface of the rail portion upward. As a result of the pressing, the lifting device main body is sandwiched between the rail portions by pressing the rail portions in opposite directions at two locations spaced at a predetermined interval along the longitudinal direction of the guide rail, and the wire is pulled. The rope is suspended and fixed by the suspension force of the rope. For this reason, the operator can pull the portion of the wire rope that intersects the skater into the skater and clamp it. As described above, the lifting device according to the present invention can maintain the lifting state of the wire rope. The operator does not need to lift and hold the heavy wire rope by himself, and also simply pulls the lifted wire rope into the skater, which is light work. As a result, even if there is only one worker, the wire rope can be reliably clamped to the skater.

[0010] When the rope supporting portion is provided at a position corresponding to the rope clamp portion of the skater along the width direction of the guide rail, the wire rope lifted by the lifting device is kept as it is. , Arranged almost directly below the rope clamp portion of the skater. Therefore, when clamping the rope clamp portion of the skater and the wire rope, the wire rope does not need to be largely moved in the width direction of the guide rail. As a result, the clamping operation becomes easier.

When the lifting tool main body is provided with a restricting member for restricting the lowering position by contacting the upper surface of the rail portion when the lifting device body is pressed down, the restricting member contacts the upper surface of the rail portion. The lifting tool body can be pushed down casually until touched. Moreover, in this state, since the locking member enters the inside of the guide rail from the upper surface opening, the operator simply rotates the locking member as it is, and moves the locking member to the rear side of the rail portion. Can be locked. Therefore, the operation is simple.

A positioning member is provided on the fulcrum and the regulating member for fitting the lifting device main body along the width direction of the guide rail by being fitted inside the opposite end of the rail portion. In this case, since the position along the width direction is determined in a state where the lifting tool is locked and fixed to the guide rail, the work of clamping the wire rope to the skater is easier.

First, the rope support 8 will be described. As shown in FIG. 1, a fulcrum pin 13 protrudes from a front end portion of the lifting tool main body 7 along a width direction of the lifting tool main body 7 at a front side thereof. , A guide roller 14 is rotatably mounted. A pair of flange portions 15 are provided at both ends of the guide roller 14 in the axial direction. The distance between the pair of flange portions 15 is slightly larger than the outer diameter of the wire rope W _11. The rope supporting unit 8, after the lifting tool A is placed on a pair of rail portions 1a of the guide rails G, are disposed below the wire rope W _11, the wire rope W ₁₁ between the pair of flange portions 15 It is for getting in and supporting.

Next, the fulcrum 11 will be described. FIG.
As shown in FIG. 2, a fulcrum shaft 16 is attached to the bent portion of the lifting tool main body 7 along the width direction thereof, and flange portions 17 are provided near both ends thereof. . The interval between the outer end surfaces of the pair of flange portions 17 is slightly shorter than the inner width of the opening V of the guide rail G. For this reason, the lifting tool A is connected to the guide rail G.
When installed on the upper surface of the rail portion 1a, the position of the lifting tool main body 7 in the width direction of the guide rail G is regulated by the pair of flange portions 17 and is always fixed. Further, the fulcrum shaft 16 has a skater S at substantially the center in the width direction of the guide roller 14 constituting the rope supporting portion 8.
Corresponding to the first and second occlusal members 4 and 5 constituting the rope clamp portion C (on the extension line immediately below the first and second occlusal members 4 and 5 in the width direction of the guide rail G).
Are different from each other in the amount of protrusion from the lifting tool main body 7 (see FIG. 5).

Next, the locking portion 12 will be described. FIG.
As shown in FIG. 3, at the rear portion of the fulcrum portion 11 (position about 2/3 from the longitudinal end of the lifting device main body 7) and on the front side thereof, the lifting device main body 7 is provided. An upright plate 18 that is substantially perpendicular to the longitudinal direction is fixed. That is, the distance from the fulcrum portion 11 to the rope support portion 8, the distance from the fulcrum portion 11 to the locking portion 12 is substantially equal length, lifting when Gaidorora 14 of the rope supporting portion 8 lifts the wire rope W ₁₁ The force and the locking force when the lifting tool main body 7 is locked and fixed to the rail portion 1a of the guide roller 14 are provided so as to be substantially the same. In a plan view, a through hole 18a is provided at a substantially central portion of the upright plate 18, and the L-shaped handle 1 is provided in the through hole 18a.
Nine rotating shaft portions 19a are inserted. The lower end protrudes below the lower end surface of the upright plate 18, and the locking plate 21 is integrally attached to the portion. Therefore, when the handle 19 is rotated, the locking plate 21 is rotated together with the handle 19. The locking plate 21 has a rectangular plate shape in a plan view, and a long side portion thereof is attached substantially in parallel with the operating portion 19 b of the handle 19. The locking plate 21 is rotated while entering the inside of the guide rail G, and is locked to the back surface of the rail portion 1a of the guide rail G. Therefore, the length of the short side portion is shorter than the inner width of the opening V of the guide rail G, and the length of the longer side portion is longer than the inner width of the opening V of the guide rail G.

The same restricting member (second restricting member) as the first restricting member of the fulcrum portion 11 is attached to the upright plate 18. That is, each regulating roll 22 is provided so as to protrude from the front portion and the rear portion of the upright plate 18 along the width direction of the guide rail G, and a pair of flange portions 23 are provided near both ends thereof. The interval between the pair of flange portions 23 is the same as the interval between the pair of flange portions 17 in the fulcrum portion 11.

Next, the operation of the lifting device A according to the present invention will be described. When the collision test of the test vehicle T is completed and the next collision test is performed, the skater S is returned to the traveling start position. Then, at this traveling start position, the skater S
Wire rope W ₁₁ the rope clamp portion C of is clamped. As shown in FIG. 4, the lifting device A is installed at a rear position near the skater S returned to the traveling start position. That is, the fulcrum shaft 16 constituting the fulcrum portion 11 is mounted on the upper surface of the rail portion 1a of the guide rail G. At this time, the outer width of the pair of flange portions 17 attached to both ends of the fulcrum shaft 16 is equal to the opening V of the guide rail G.
The width of the guide rail G in the lifting tool main body 7 in the width direction is determined because the pair of flange portions 17 enter the opening V slightly smaller than the inner width of the guide rail G. That is, the guide roller 14 of the rope support portion 8 is disposed at a position corresponding to the first and second occlusion bodies 4 and 5 constituting the rope clamp portion C of the skater S. The first bite 4 is
Have lowered downwards, between each occlusal 4, 5, sufficient space is formed in order to enter the wire rope W _11. In FIG. 4, reference numeral 20 denotes an escapement for releasing the connecting wire 54.

The operating portion 7a of the lifting tool main body 7 is rotated counterclockwise about the fulcrum shaft 16 and slightly pushed up, and the front half thereof is inserted into the inside of the guide rail G through the opening V, to arrange the guide roller 14 of the rope supporting portion 8 below the wire rope W _11. Then, as shown in FIG. 5, the wire rope W ₁₁ is pushed in a horizontal plane, and a pair of flange portions 15
Let it in between and support.

In this state, the operating section 7a of the lifting tool main body 7
Is rotated clockwise about the fulcrum shaft 16 and pushed down, so that the wire rope W ₁₁ supported by the guide roller 14 (the portion of the wire rope W ₁₁ that intersects the skater S) is lifted. The locking plate 21 constituting the locking portion 12 has its long side portion previously arranged at a position along the longitudinal direction of the lifting tool main body 7. In addition, a regulating roll 22 for regulating the position where the lifting tool body 7 is pressed down is attached to the locking portion 12. For this reason, even when the operation part 7a of the lifting tool main body 7 is pressed down as it is, the regulating roll 22 is stopped by abutting on the upper surface of the rail part 1a of the guide rail G. Therefore, the operation is simple. At this time, the locking plate 21 enters through the opening V of the guide rail G. The operator sets the handle 19 to approximately 90 °
By rotating, the locking plate 21 is disposed at a position orthogonal to the longitudinal direction of the lifting tool main body 7. Since the length of the long side portion of the locking plate 21 is longer than the inner width of the opening V of the guide rail G, the back surfaces of the pair of rail portions 1a and the upper surface of the locking plate 21 abut. The lifting tool body 7
Presses the rails 1a in opposite directions at two places (a fulcrum shaft 16 and a locking plate 21) at a predetermined interval along the longitudinal direction of the guide rail G, so that the rails 1a are pressed. in a state sandwiched, it is locked fixed by suspension force of the wire rope W _11. As a result of the above, the guide roller 14 is held in a state of lifting the wire rope W _11.

The operation at this time will be described in further detail.
I do. As shown in FIG. 8, in the locked and fixed state,

Therefore, the lifting device A according to the present invention includes a wire rope W₁₁No suspension
Vertical force F₁Is larger, the rail portion 1a of the guide rail G
Since the locking fixing force against the wire rope W becomes large, the wire rope W₁₁
Suspension force F₁It can be said that it is a skillful use of.

As the value of (L ₁ / L ₂ ) is larger,
That is, the horizontal length L ₁ between the guide roller 14 and the fulcrum shaft 16
When the position of the locking plate 21 is closer to the fulcrum shaft 16, the lever portion 1a
, The locking and fixing force of the lifting tool A with respect to is increased. on the other hand,
The operation unit 7a of the lifting device main body 7, as the distance between the grip portion 7b and the fulcrum shaft 16 is increased, Te because it requires in the downward force is small due to this principle, the work lifting of the wire rope W ₁₁ is facilitated. However, since the lifting tool A according to the present invention is presumed to be operated alone, the distance between the handle 7b and the locking plate 21 is determined from this viewpoint, and cannot be largely separated. . Therefore, in terms of design, the distance is desirably set to a distance at which the operator can work alone, that is, a maximum distance at which the handle 19 for rotating the locking plate 21 can be operated while holding the handle 7b. .

Next, as shown in FIG.
The same operation as above is performed in front of the skater S. By doing so, the wire rope W ₁₁ is lifted by a pair of lifting members A, it is held substantially upright (substantially horizontal state). In addition, the guide roller 14 of each rope supporting portion 8 is disposed at a position corresponding to the rope clamp portion C of the skater S. This wire rope W ₁₁ lifted it is meant that is disposed between the first and second respective occlusal 4, 5 as it is. As shown in FIG. 10, tightened the fastening bolt 3 which constitutes the rope clamp portion C of the skater S, the wire rope W ₁₁ the first and second respective occlusion of 4,5
Is clamped by In this way, the wire rope W ₁₁ is clamped to the rope clamp portion C of the skater S.

During the operation described above, the guide rollers 14 of the rope supporting portions 8 are moved by the locking portions 12 so that the wire rope W
₁₁ is held in a raised state. Thus, even a worker a person, it is possible to perform the clamping work of the wire rope W _11. Further, in the lifting tool main body 7, a pair of flange portions 17 attached to both ends of the fulcrum shaft 16 and a pair of flange portions 23 attached to both ends of the regulating roller 22 in the locking portion 12 are formed by guide rails. The lifting tool A is fitted into the opening V of the G and the rotation of the lifting tool A in the horizontal plane is restricted. For this reason, the worker can work accurately.

As shown in this embodiment, the case where two wire ropes W ₁ and W ₂ are accommodated inside the guide rail G means that the test vehicle has the same running start position and the On two straight roads that differ only in position,
This is a case where the guide rail G on the shorter running distance is shared. Even in such a case, the work is easy because only one of the wire ropes W ₁₁ and W ₂₁ to be clamped needs to be slightly moved in the width direction of the guide rail G.

A rope support portion for supporting a wire rope is provided at one end side of a fulcrum portion provided at a middle portion in the longitudinal direction of the lifting tool main body, and is locked to a rail portion of a guide rail at the other end side. Locking portions are provided. For this reason, the rope supporting part can hold the state in which the wire rope has been lifted, and even if there is only one worker, the wire rope can be reliably clamped on the clamp part of the skater.
