Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an elevating type hanging gutter provided in a waterway that crosses over a three-dimensional intersection, and when the hanging gutter is lifted by the load of a balance weight, the load of the balance weight is changed to a column. Does not act as a lateral force that causes the vehicle to fall.

(Prior Art) As an elevating hanging gutter, for example, as disclosed in Japanese Patent Application Laid-Open No. 62-13607, at an intersection between an upper channel and a lower channel of two waterways that cross over each other. It is known that a hanging gutter is arranged so as to be able to move up and down, and when the lower waterway rises, the hanging gutter is raised by a load of a balance weight so as not to obstruct the flow of water in the lower waterway. .

(Problems to be Solved by the Invention) However, in the above-mentioned conventional elevating hanging gutter, since the wire for supporting the load of the balance weight is stretched between the columns, the wire of the wire due to the load of the balance weight is stretched. There is a possibility that the tension acts on the support and the support in the lateral direction of drawing the support to each other, and the support is overturned. If the struts are to be firmly constructed to resist this lateral force, the facility must be enlarged. In addition, when the balance weight becomes heavier as the length of the hanging gutter becomes longer, it becomes necessary to build the columns more and more firmly.

Therefore, an object of the present invention is to provide means capable of coping with an increase in the length of a hanging gutter by preventing a load of a balance weight from acting on a lateral direction in which a column is easily overturned.

(Means for Solving the Problems) For this purpose, in the present invention, in this type of hoisting gutter, columns 4 and 5 are erected on both sides of the hanging gutter 3 and a balance weight 6 is provided between the columns 4 and 5. , And a pulley device 7 for suspending the hanging gutter 3 up and down on each of the columns 4 and 5. The tuning band 7c wound around the pulley device 7 has one end attached to a mounting portion 7d provided at a corner of the balance weight 6, and the other end is connected to both sides of the hanging gutter 3, A pulley device 13 for raising the balance weight 6 is disposed on the columns 4 and 5, and a pull-down preventing device 30 for the balance weight 6 is provided.

(Operation) In the above configuration, when the lowering prevention device 30 of the balance weight 6 is operated and the lowering prevention state of the balance weight 6 is released, the balance weight 6 starts to lower by its own weight, and the adjusting bands 13i, 13k is rewound, and the hanging gutter 3 connected to the balance weight 6 via the adjustment band 7c of the pulley device 7 rises.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 are an overall view and a side view of an elevating hanging gutter. Reference numeral 3 denotes a hanging gutter provided at the intersection of the upper waterway 1 and the lower waterway 2 so as to be able to move up and down, and its raising and lowering mechanism will be described below.

Reference numerals 4 and 5 denote struts made of reinforced concrete or the like provided on both sides of the gutter body 3, respectively. The hanging gutters 3 are arranged between these struts 4 and 5 so as to be able to move up and down and hung on the water channel 2. Has been passed. Numeral 6 is a substantially long plate-shaped balance weight bridged between the columns 4 and 5. Reference numeral 7 denotes two pulleys, two on each of the columns 4 and 5, for suspending and supporting the four corners of the balance weight 6. Each of the pulley devices 7 includes a pulley 7a disposed on the upper surface side of the columns 4,5.
And pulleys 7b installed on the lever member 10c of a booster 10 (described in detail later), which are disposed on both sides of the hanging trough 3 and adjust the tension wound around these pulleys 7a and 7b. One end of the adjusting band 7c is wound around a fixture 7d provided at a corner of the balance weight 6, and the other end is wound around a pulley 7b. , 5 are mounted on a mounting member 7e. Note that this fixture 7e is a pulley
It also serves as the support frame 7a (see also FIG. 4). In addition, instead of the pulley 7b, the same attachment as the above-mentioned attachment 7d is provided on the lever member 10c, and the other end side of the adjustment band 7c may be connected to this attachment, so that the pulley 7b is not necessarily required. Good. If the balance weight 6 is bridged between the columns 4 and 5 and the four corners are suspended and supported by four independent pulley devices 7, the load of the balance weight 6 can be reduced. , Acts as a force in the vertical direction, so that it is possible to prevent the columns 4, 5 from tipping over due to the lateral force acting on the columns 4, 5. Reference numeral 12 denotes a stopper that regulates the temperature at which the balance weight 6 descends.
The lower ends of both sides of 5 extend integrally with the columns 4 and 5.

The intensifier 10 raises the hanging gutter 3 with a small force, and as shown in FIG. 3, a receiving member 10a for supporting the side end of the hanging gutter 3 from below, and an upper end of the receiving member 10a. A lever member 10c that is rotatably pivoted about the pin 10b, and an upper end portion is pivotally connected to a rear end portion of the lever member 10c via a pin 10d,
The lower end portion is made of a leg material 10e that lands on the base, and the pulley 7b is formed on the upper end of the lever member 10c as described above.
Are arranged. Length L1 from pin 10b to pulley 7b
Is much longer than the length L2 from the pin 10b to the pin 10d. Therefore, when the adjusting band 7c is lifted upward by the load of the balance weight 6, the lever member 10c is relatively moved around the pin 10d by the leverage principle. The gutter 3 is lifted while rotating counterclockwise with a small force. Further, since the pulley 7b is a moving pulley, the hanging gutter 3 can be pulled up with half the force when the pulley 7b is not attached. Note that the other intensifiers 10
It has the same structure as. Therefore, by using the intensifier 10 and the pulley device 7, the principle of leverage and the principle of pulley are used together.
Can be lifted.

Reference numerals 17 and 18 denote tuning shafts connecting the pulleys 7b and 7b on the lever members 10c on both sides of the hanging trough 3, and always keep the same amount of rotation of each pulley 7b so that the pulling gutter 3 is in a horizontal state without tilting. It is for raising and lowering as it is. Reference numeral 13 denotes a pulley device for raising the balance weight 6 disposed on each of the columns 4 and 5, and is coaxially disposed on the upper portion of the column 4 as shown in a simplified form in FIG. A pair of winding drums 13
a, 13b, a pulley 13c provided on one support 4, a pulley 13d provided on the other support 5, and pulleys 13e, 13f, 13g, 13h provided at corners of the balance weight 6. Consists of The adjusting band 13i wound around one drum 13a is wound around pulleys 13e, 13c, 13f, and its end is attached to a support frame 13j of the pulley 13d, and the other drum 13b
The adjusting band 13k wound around is wound around pulleys 13g, 13d, 13h, and its end is attached to the frame 13j. In addition, pulleys 13e and 13h use tuning bands 13i and 13k as pulleys 13c and 13d, respectively.
In order to form closed loop portions a and b by turning around, a double pulley is formed (see FIG. 6). Thus each pulley
By disposing the closed loop portions a and b on the winding route of 13i and 13k separately to the left and right, the balance weight 6 is prevented from inclining in the length direction (left and right in FIG. 2).
Therefore, the closed loop portions a and b serve as tuning means in the length direction.

Reference numeral 30 denotes a fall prevention device for the balance weight 6 which is an automatic device disposed on the side of the column 4, 31 denotes a float as a water level detector for detecting the water level of the lower waterway 2 connected to the automatic device 30, Reference numeral 32 denotes an operation handle for winding up the balance weight 6 and lowering the hanging gutter 3. The automatic device 30 is composed of a well-known one-way clutch in which a stopper 34 is detachably engaged with a ratchet wheel 33, and includes a sprocket 3 attached to the ratchet wheel 33 and the rotating shaft of the drums 13a and 13b.
5 has a chain 36 tuned, and the stopper 34 is a pawl 3
The engagement with 3 prevents the ratchet wheel 33 from rotating in the downward direction of the balance weight 6 due to the load of the balance weight 6. When the lower channel 2 rises and the float 31 floats, the stopper 34 separates from the ratchet wheel 33 due to the buoyancy of the float 31, and the ratchet wheel 33 becomes free.
The balance weight 6 is lowered by its own weight while rewinding the adjusting bands 13i and 13k of the pulley device 13, and the hanging gutter 3 connected to the balance weight 6 by the adjusting band 7c of the pulley device 7 is raised.
Operate the handle 32 to adjust the tuning bands 13i, 13k to the drums 13a, 13b.
The balance weight 6 is wound up, and the hanging gutter 3 descends. Instead of using the handle 32, the drums 13a and 13b are rotated by power means such as a motor to adjust the adjustment bands 13i and 1b.
You may make it wind 3k.

This elevating hanging gutter has the above-described configuration, and its operation will be described next.

Usually, the hanging trough 3 is at the lowered position. When the lower channel 2 rises, the float 31 floats, the stopper 34 is disengaged from the ratchet 33, and the balance weight 6 descends by its own weight.
At the same time, the lever members 10c of the intensifier 10
The tip is pulled up to the adjustment band 7c via b, and the pin 10d
Rotate around. When the balance weight 6 is further lowered, the hanging gutter 3 is lifted by the receiving member 10a and rises. When the four corners of the balance weight 6 land on the stoppers 12 extending at the lower ends of the columns 4, 5, the rising of the hanging gutter 3 is stopped. And
Thereafter, since the hanging gutter 3 maintains its position, the water in the upper channel 1 falls to the lower channel 2. As described above, the present apparatus is configured to automatically raise the hanging gutter 3 on the upper waterway 1 side which intersects with the lower waterway 2 when the lower waterway 2 has increased water. It does not obstruct the flow.

By the way, when the hanging gutter 3 starts to rise, water is present in the hanging gutter 3, so that the weight of the hanging gutter 3 is extremely heavy. Therefore, a large lifting force is required to start the lifting of the hanging trough 3. However, since the present device utilizes this principle and the pulley principle as described above, even the relatively lightweight balance weight 6 can be used without fail. The rise of the hanging gutter 3 can be started. In addition, the hanging trough 3 rises and the leg material 10 of the intensifier 10
When e moves away from the base, the leverage principle does not work, but at that time, since the water in the hanging trough 3 has already fallen in the lower channel 2, the hanging trough 3 is light, 3 can be reliably raised. To lower the hanging trough 3, use the operation handle
If the ratchet wheel 34 is rotated in the upward direction of the balance weight 6 by operating the 30, the adjusting bands 13 i, 13 k are wound around the drums 13 a, 13 b, the balance weight 6 rises, and the hanging gutter 3 descends.

(Effects of the Invention) As described above, in the present invention, in this type of elevating hanging gutter, columns 4 and 5 are erected on both sides of the hanging gutter 3, and the balance weight 6 is hung between the columns 4 and 5. A pulley device 7 for suspending the hanging gutter 3 so as to be able to move up and down is provided on each of the columns 4 and 5, and one end of an adjusting band 7 c wound around the pulley device 7 is connected to a corner of the balance weight 6. At the same time, the other end side is connected to both sides of the hanging gutter 3, and the pulleys 13 for lifting the balance weight 6 are provided on the columns 4 and 5. Since the lowering prevention device 30 for the balance weight 6 is provided, the load of the balance weight 6 acts on the columns 4 and 5 as a vertical load and does not act as a force in the horizontal direction, that is, a direction in which the columns 4 and 5 are overturned. To prevent the pillars 4 and 5 from tipping over. It may correspond to the lengthening of.
