Description

TECHNICAL FIELD The present invention relates to a forward / reverse drive transmission device for attachment / detachment / tightening / loosening of a container for lifting, etc., and particularly swinging drive by reversing in a forward / reverse direction with a hydraulic cylinder or an electric motor. The present invention relates to a forward / reverse drive transmission device that can be sequentially rocked in forward / reverse directions simply by pulling in the same direction via a pulling tool such as a wire rope.

Conventional technology Conventionally, shipping containers are raised and lowered,
Lifting equipment is used for unloading. Then, in order to attach / detach the hoisting device to / from the container, the detachable drive device provided in the central portion or the like is operated to pull the draft and the auxiliary draft, and the hanging metal fittings of the hoisting device are simultaneously rotated 90 degrees in forward and backward directions, It was done by engaging and releasing the hanging fittings and the receiving fittings on the container side.

However, the operation of the attachment / detachment drive device is performed by suspending the operation cords at both ends of the operation lever, pulling the left and right operation cords respectively in accordance with the attachment / detachment operation of the lifting device, and pulling the hanging metal fittings in the forward and reverse directions. I had to turn it around.

Problems to be solved Therefore, in order to remotely control the lifting device and attach / detach it to / from the container, a drive source for pulling the operation cords of the operation lever of the attachment / detachment drive device is required, resulting in high cost and complicated control. It was a change.

Further, even in the case of manual operation, in the conventional one, the left and right operation cords for operating the operation lever of the attachment / detachment drive device as described above must be pulled respectively, and the pulling side of the operation cord must be pulled. There was something wrong.

Means for Solving the Problems The present invention has been made in view of the above points, and in order to solve the above problems, a transmission rocking member for transmitting drive to an external actuating device is shaken in the apparatus body. A forward / reverse drive member that is movably pivoted and swings by being pulled by a pulling tool such as a wire rope is pivotally attached to the apparatus main body, and a part of the forward / reverse drive member is transmitted to the transmission swing member. The transmission oscillating member is arranged so as to be oscillatably driven by being hooked on a part of the engaging portion, and a reversing member is provided on the side opposite to the pulling side with respect to the pivoting portion of the forward / reverse driving member as a forward / reverse driving member. Symmetrically and foldably so as to be reversible, and one end of the inversion elastic material is locked to the tip end side of the inversion member to constantly rotate the inversion member around the pivot portion of the main body of the apparatus. The other end of the reversing elastic member to the pivot part of the main body so that When the forward / reverse driving member is not pulled, the reversing elastic member pulls the reversing member around the pivot portion of the apparatus main body by a pivoting moment and abuts on the guide / combining stopper to cause the forward / reverse driving member. When the forward / reverse driving member is stopped by pulling the forward / reverse driving member through the pulling tool to swing the transmission rocking member in one direction, the guide is guided in the middle of the guide rocking member. The reversing member is arranged so as to be bent from the straight line and the L-shaped drive member in a straight line with the forward / reverse driving member by a dual-purpose stopper so that the reversing member is turned to be reversed through the reversing elastic member. When loosened, the reciprocating drive member is revolved by pulling the reversing member revolved by a revolving moment around the pivotal portion of the apparatus main body by the reversing elastic material, and the transmission oscillating member oscillating first. Can be swung to pull back to the other end To provide a forward and reverse drive transmission device being characterized in that disposed.

Effect According to the present invention, when the forward / reverse drive device is pulled through the pulling tool such as a wire rope, the transmission / oscillation member is swung in one direction via the forward / reverse drive member, and the guide / stopper is also provided on the way. When the reversing member is reversed with and the traction tool is loosened, the forward / reverse driving member is rocked by pulling so that the forward / reverse driving member returns to the original direction due to the elastic force of the reversing elastic material having one end locked to the reversing member. It is located at the engagement portion on the swing drive side in the direction opposite to the above of the member. Therefore, when the forward / reverse driving member is then pulled via a pulling tool such as a wire rope, the transmission swinging member can swing in the direction opposite to the above, and the forward swinging member can be swung forward via the reversing member in the same manner as above. The reverse drive member can be reversed again to the position where the next transmission swing member swings in the opposite direction. In this way, by simply pulling the forward / reverse drive device in one direction at all times, the transmission oscillating member can be oscillated in the forward rotation direction and the reverse rotation direction in sequence, and the required operating device can be operated.

Embodiment Hereinafter, the present invention will be described based on an embodiment.

FIG. 1 and the following are embodiments of the present invention. As shown in FIGS. 1 and 2, the forward / reverse drive transmission device 1 has a forward / reverse drive member 3 pivotally attached to the central portion of a device body 2 having a rectangular box shape, and a rectangular shape on its side peripheral portion. A frame-shaped transmission rocking member 4 is pivotally attached,
By pulling the forward / reverse drive member 3 manually or by an automatic device (not shown) via a pulling tool 5 such as a wire rope,
As shown in FIGS. 3 and 4, the transmission rocking member 4 is formed so as to be rockable over a predetermined angle. The forward / reverse driving member 3 is the fourth
As shown in the figure, it is formed by joining in a substantially U shape.
As shown in FIGS. 2 and 2, the substantially central portion thereof is pivotally attached to the fixing member 6 in the central portion of the apparatus main body 2, and the end portion of one member joined to the upper portion of the central portion of the apparatus main body 2 has a required strong elasticity. The first elastic material 7 having a force and the second elastic material 8 having a slightly weak force are connected and connected to each other so as to avoid the top dead center at the time of reversal described below. The ends of the other members joined to the forward / reverse driving member 3 are semi-circular, and the block-shaped reversing member 9 is provided around the semi-circular portion 11 via the pivot portion 10 as shown in FIGS. Inversion elastic material 12
It is pivotally supported at 180 degrees. Inside the center of the device body 2 of the reversing member 9, guide stoppers 19 and 20 are symmetrically arranged as shown in FIG. 1, and one side surface of the reversing member 9 is slid on the guide stopper 19 or 20. In the contact state, the reversing member 9 is bent in a straight line with the forward / reverse driving member 3 and the reversing member 9 is bent with the reversing elastic member 12 in the predetermined direction around the above-mentioned pivotal support portion 10 as shown in FIGS. 4 and 5. I am trying to do it. The reversing elastic member 12 which is formed by bending the reversing member 9 into an L-shape is shown in FIGS. 1 to 3 from the forward and reverse driving members 3 at the center of the apparatus main body 2 and the pivotally connecting portions of the transmission rocking member 4. Projection fixing member 12A arranged slightly eccentrically downward like
To one end and the other end to the tip side of the reversing member 9,
The forward / reverse drive member 3 is constantly pulled by the turning moment by the elastic force of the reversing elastic member 12 via the reversing member 9 so that it can be revolved in the left and right directions around the center of the apparatus main body 2 at all times. Then, the joining portion 13 at one end of the forward / reverse driving member 3
When the forward / reverse driving member 3 is pulled upward through the pulling tool 5 such as a wire rope suspended on the upper side, the forward / reverse driving member 3 pushes up the engaging portion 14 of the frame-shaped transmission rocking member 4 at one end. The transmission rocking member 4 rotates 90 degrees and comes into contact with the frame 15 of the apparatus main body 2 to stop. Then, when the forward / reverse drive member 3 is turned, as shown in FIG.
The reversing elastic material 12 is extended so as to be in line with the forward / reverse driving member 3 via 19, and when the forward / reverse driving member 3 further swivels, the reversing member 9 is bent by the guide and stopper 19. As shown in FIG. 5, the reversing member 9 is swung vertically with respect to the forward / reverse driving member 3 by the elastic force of the reversing elastic member 12.
When the pulling tool 5 is pulled and tightened in this way, the forward / reverse driving member 3 is pulled in the original direction as shown in FIG. 6 by the elastic force of the reversing elastic member 12 attached to the reversing reversing member 9. As shown in FIG. 7, the reversing member 9 has a stopper 20 that also serves as a guide.
, And the frame-shaped engaging portion 16 at the other end of the transmission rocking member 4 which rocks the forward / reverse drive member 3 as shown in FIG. 3 is positioned so as to be pushed up next. Numerals 17 and 18 are guide rollers for the towing tool 5, and numerals 21 and 22 are integrally formed on both sides of the central portion of the transmission oscillating member 4 in order to transmit the oscillation of the transmission oscillating member 4 to a required external operating device. It is a transmission shaft in the form of a square shaft that is physically attached.

Therefore, for example, the forward / reverse drive transmission device is installed in the forward / reverse drive unit for rotating the hanging fitting of the lifting device described in JP-A-62-25985 or the like in the forward / reverse direction, and the remote control device is connected to the traction tool. . When the pulling tool 5 is pulled by the remote control automatic device in the state shown in FIG. 1, the forward / reverse drive member 3 resists the reversing elastic member 12 and moves around the central axis thereof as shown by the alternate long and short dash line in FIG. By rotating clockwise, the transmission rocking member 4 is swung via the engaging portion 14 as indicated by the alternate long and short dash line in FIG. 1, and the hanging metal fitting of the lifting device can be swung via the transmission shafts 21 and 22 at the center thereof. .
At that time, the reversing member 9 pivotally supported on one end side of the forward / reverse driving member 3.
Slides on the guide / stopper 19 and turns counterclockwise as shown in FIGS. And the towing tool 5
When slackened, one end is locked to the tip of the inverted reversing member 9 and the other end is slightly eccentric from the center of the device main body 2 around the center of the device main body 2 due to the elastic force of the reversing elastic material 12 locked. The forward / reverse drive member 3 can be rotated in the original direction by the turning moment generated in the above direction, and the forward / reverse drive member 3 can be reversed to the other end side of the transmission oscillating member 4 which is oscillated as shown in FIGS. 6 and 7. .
At this position, when the pulling tool is pulled and loosened again by the remote control automatic device, the forward / reverse driving member 3 and the transmission rocking member 4 can be turned and reversed in the opposite direction in the same manner as described above. In this way, as described above,
The hoisting device of the hoisting device can be sequentially rotated forward and backward, and can be reliably attached to and detached from the receiving device of the container. Therefore, the remote control of the container can be simplified, and erroneous operation of attaching and detaching the lifting device can be prevented, so that the work can be performed quickly and safely.

In the above-mentioned embodiment, the stopper of the transmission rocking member is used as the upper frame of the apparatus main body so that it can be swung 90 degrees to the left and right in the forward and reverse directions.However, a stopper having a required rigidity is provided to make 90 degrees, an acute angle, an obtuse angle. It is also possible to swing over a required angle such as.

Further, in this embodiment, when the forward / reverse drive member is reversed by connecting the first elastic material and the second elastic material of the strong elastic material and the weak elastic material to each other, the forward / reverse drive member may stop at the top dead center. Although it is possible to avoid it in consideration of a special case, it is also possible to deal with it by means such as attachment of own weight or counter balance.

Further, in the above description, the pulling tool is the wire rope, but it may be a chain or other substitutes, and the forward and reverse drive members, the transmission rocking member, and the elastic material also exhibit the above-described actions and effects of the present invention. Appropriate changes can be made within the range, and the forward / reverse drive member and the transmission rocking member can be engaged with each other by additionally providing a contact engagement member. .

The application of the present invention is not limited to the container lifting device, but can be similarly applied to other attachment / detachment and fastening devices.

As described above, according to the present invention, the reversing member is reversibly bendable at the end of the forward / reverse driving member, one end is locked to the reversing member, and the other end is attached to the main body 2 of the apparatus. Since the forward / reverse drive member can be swung by pulling by the turning moment generated around the center of the device body by the elastic force of the reversing elastic material that is slightly eccentric from the center and locked, the drive device of the hydraulic cylinder or electric motor By simply pulling the forward / reverse drive member in the same direction via a pulling tool such as a wire rope, it is possible to swing the transmission swing member sequentially in the forward direction and the reverse direction without reversing the direction and driving the swing. It is easy to operate, easy to operate, and safe to operate.
