[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rack-type water gate or gutter gate door lifting device installed in a non-electrified area where power lines cannot be drawn.

[0002]

2. Description of the Related Art Generally, gates and gutters are provided with a driving device incorporating a motor and a motor for raising and lowering a door body. However, relatively small ones are manually operated by operating a steering wheel. The door is driven up and down. In addition, sluice gates and gutters are generally installed in non-electrified areas, and in recent years, electrification work is often restricted for environmental conservation reasons. This type of manual lifting device had to be used.

FIG. 6 is a front view showing a conventional example of this kind of a door manual lifting device, and FIG. 7 is an enlarged sectional view taken along the line AA of FIG. As shown in the figure, the door body manual lifting device has a ladder-like rack bar 33 having pins 33a arranged in rows at predetermined intervals, and is mounted so as to vertically pass through the main body 32 of the lifting device. And this rack bar 33 is
The pin 3 is inserted inside the main body 32 so that the
3 a meshes with the pin gear 34.

A shaft 35 having a pin gear 34 attached thereto is
Engage with a relay shaft 37 arranged on one side of the main body 32 via a gear 38 meshed with a gear 36 fixed coaxially,
The relay shaft 37 is engaged with a shaft 44 on the other side via a gear 39, a gear 40, a gear 41, a gear 42, and a gear 43. This shaft 44 is a handle shaft 3 to which the handle 31 is fixed via a differential gear device 45 or a power transmission mechanism (not shown).
0 is engaged.

[0005] Although not shown, the relay shaft 37 is connected to a relay shaft of a similar manual door lifting and lowering device via a shaft (not shown) so that the rack rods 33 attached to the respective relay shafts can be driven in synchronization. It has become. Further, a door (not shown) of a water gate or a gutter gate is fixed to a lower end of each rack bar 33, and the door is suspended and supported by a pair of rack bars 33.

Therefore, when the handle 31 is rotated, the rotational force of the handle 31 is transmitted to the pin gear 34 at a reduced speed via a power transmission mechanism such as the gears 39 to 43, and the rack meshed with the pin gear 34. The rod 33 is driven in the vertical direction. Therefore, the door attached to the lower end of the rack bar 33 is driven up and down to open and close a water gate and a gutter gate.

In FIG. 7, reference numeral 47 indicates a dead weight changeover lever for lowering the door by its own weight, and reference numeral 46 indicates a centrifugal brake device for controlling the door so that no acceleration is applied at that time.

Although not shown, this type of door body manual lifting device is provided with a self-locking device so that the door body does not descend even when the handle 31 is released.

[0009]

In the above-described conventional manual lifting device for a water gate or a gutter gate, the rotation of the handle shaft is reduced and transmitted to the pin gear. Even at floodgates and gutters, the operating load of the door body is quite large, and opening it with human power alone was a very heavy labor requiring several hours.

If this type of lifting device is not used for a long period of time, it may not be able to be driven at an emergency due to rust or the like. Therefore, it is obliged to periodically open and close the door. ing. However, since the work is very hard work as described above, it is almost impossible to completely open and close the door to check the operation.

It is also possible to attach an adapter to this type of manual elevating device and operate it using a motor or a prime mover. In this case, however, it takes time for setting, securing power supply and carrying in fuel. There was a new problem that had to be solved. Furthermore, since this motor or prime mover is installed outside the lifting device, there is a problem in safety, and a manual lifting device designed on the assumption of driving by human power is forcibly driven using a driving source. This may cause unexpected failures and troubles.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the problems of the above-mentioned conventional door gate elevating device for a water gate or a gutter.

[0013]

In order to solve the above-mentioned problems, the invention according to claim 1 of the present invention is characterized in that a pin gear meshed with a rack rod that suspends and supports a door is provided with a motor.

In the middle of the torque lever 8, an arc-shaped gear 8 a having teeth coaxially with the rotation center of the torque lever 8 is attached, and this gear 8 a is attached to a variable resistor 9 fixed to the casing 4. It meshes with a gear 9b fixed to the shaft 9a.

An auxiliary drive device is provided below the drive shaft 6. The auxiliary drive device includes a motor 3 and a gear transmission mechanism that transmits the rotational force of the motor 3 to the drive shaft 6 at a reduced speed. The gear transmission mechanism includes a gear 18b meshed with a gear 3b fixed to the shaft 3a of the motor 3.
And a gear 18 fixed to the same shaft 18 as the gear 18b.
a, a gear 17a meshed with the gear 18a, and a gear 17a fixed to the same shaft 17 as the gear 17a and meshed with the gear 14 fixed to the drive shaft 6.

The motor 3 is connected to a battery 51 via a control circuit (not shown) so as to be driven and controlled based on the measured value of the variable resistor 9. As shown in FIGS. 2 and 3, the battery 51 is arranged around an opening A ′ for penetrating a rack bar formed on the upper surface of the lifting / lowering apparatus main body A. Also, this battery 5
Around the device 1, a charging solar panel 50 connected to the battery 51 is provided in a rectangular tube shape.
Therefore, the solar panel 50 functions as a rack cover that covers a space above the rack bar 33 and that also functions as a storage container for storing the battery 51. In FIG. 2, reference numeral 52 denotes a top plate that covers the upper surface of the battery storage space formed by the four solar panels 50, and 53 denotes a fixture for fixing the stored batteries 51.

The gear 14 fixed to the drive shaft 6 is provided with a plurality of through holes 14a concentrically, and at a predetermined position of the casing 4 facing the through holes 14a, the presence or absence of the through holes 14a is determined. A sensor 16 for detecting the rotation of the drive shaft 6 and a control means of the auxiliary drive device based on the rotation speed of the sensor 16 are provided.

1 shows a bearing rotatably supported by a bearing.

Next, the operation of the above-structured water gate or gutter gate door lifting device of the present invention will be described.

First, for example, when the handle 2 is driven to rotate clockwise, the rotating member 7d supporting the planetary gear 7b of the planetary gear unit 7 rotates via the input shaft 5 to which the handle 2 is attached. As a result, the sun gear 7a and the ring gear 7c meshed with the planetary gear 7b receive the force of rotating in the same direction, but the ring gear 7c is connected to the handle shaft 30 via the drive shaft 6, and the handle shaft 30 Has a load on the door (not shown).
The ring gear 7c does not easily rotate, and the planetary gear 7b moves in the reverse direction (counterclockwise) with the rotation of the rotating member 7d.
, And a stronger clockwise force acts on the sun gear 7a. Therefore, the torque lever 8 fixed to the sun gear 7a also tries to rotate in the same direction, but on the right side of the torque lever 8 is a retractable rod 10 biased by a spring 12.
Is provided, the torque lever 8 is connected to the spring 1
Push the retractable rod 10 to some extent against the urging force of 2,
It rotates as shown by the two-dot chain line in FIG. And spring 1
2, the torque acting on the torque lever 8,
When the rotation torque of the ring gear 7c is exceeded, the sun gear 7
a does not rotate any more, this time the planetary gear 7b rotates clockwise, and the ring gear 7c starts rotating. The ring gear 7c rotates the handle shaft 30 via the drive shaft 6, and by the rotation of the handle shaft, the door body is pulled up and the water gate and gutter gate are opened as in the conventional case.

In this case, the gear 14 fixed to the drive shaft 6 is simultaneously driven by the motor 3 of the auxiliary drive device in the water gate / gutter gate door lifting device of the present invention. Although this driving force increases and decreases in accordance with the operating force of the handle 2, the operating force of the handle 2 is merely reduced, and will not operate unless the handle 2 is operated.

Next, the control of the auxiliary driving device will be described. First, when the handle 2 is operated, as described above, the spring 12 contracts according to the force, and the torque lever 8 rotates within a predetermined range. The arc gear 8a attached to the torque lever 8 also rotates around the input shaft 5, and rotates the meshed gear 9b. Since the variable resistor 9 is attached to the gear 9b, the degree of the rotation of the torque lever 8 against the biasing force of the spring 12, that is, the magnitude of the input torque from the handle 2 is determined by the variable resistor 9. Table 9
Is measured electrically. The measured value is input to a control circuit (not shown), and a current value to be supplied to the motor 3 is determined based on the value. When the input from the steering wheel 2 is small, the drive shaft 6 is rotationally driven with a small torque. When the input from the steering wheel 2 is large, the drive shaft 6 is rotationally driven with a large torque corresponding to the input.

Therefore, when the handle 2 is operated slowly and with a slight force, or when a strong force acts on the handle 2 in order to resist the load and to turn the handle 2 strongly or to operate at a high speed. In this case, the auxiliary drive device operates according to the operation force, and acts to reduce the burden on the worker. At this time, a signal from a sensor 16 that senses the rotation of the drive shaft 6 and its speed is also input to the control circuit,
If the driving of the motor 3 is controlled based on the measured value of the variable resistor 9, the operation of the auxiliary driving device can be controlled more accurately and precisely.

When the operation of the handle 2 is stopped, a self-locking mechanism (not shown) provided inside the main body A is operated, so that a force in the reverse direction does not act on the drive shaft 6. Therefore, the torque lever 8 stops at the neutral position, and the variable resistor 9 does not sense the movement, so that the auxiliary drive device does not operate and the drive shaft 6 is not driven.

In order to lower the door, it is sufficient to operate the self-weight lowering switching lever 29, and the door lowers to some extent by its own weight. However, since the door is affected by water pressure and the like, the door must be forcibly lowered to completely close the door. At this time, in the door body manual lifting / lowering device of the sluice gate or the gutter gate of the present invention, the handle 2 may be driven to rotate in the opposite direction to that described above.
With the operating force of the handle 2 and the driving force of the auxiliary drive device corresponding to the operating force, the steering wheel 2 is strongly pushed downward, completely opposite to the above.

At this time, the torque lever 8 rotates in the opposite direction to the above, and presses the retractable rod 11 on the other side (the left side in FIG. 5) against the urging force of the spring 13, and the torque value at this time Is measured by the variable resistor 9, the driving of the motor 3 of the auxiliary driving device is controlled in the same manner as described above. However, at this time, the direction of power supply from the battery 51 to the motor 3 is reversed, and the motor 3 rotates in the opposite direction.

When the door is completely lowered,
Since the drive shaft 6 does not rotate any more, the state at this time is sensed by the sensor 16 and the motor 3 of the auxiliary drive device stops. Therefore, in this state, handle 2
No matter how strong the power is operated, the auxiliary drive does not operate,
There is no fear that an excessive load is applied to the power transmission mechanism or the like. The sensor 16 has a through hole 14a formed in the gear 14.
The sensor 16 senses its rotation and speed by passing in front of it.
Any device may be used as long as it can detect the rotation of the device and its rotation speed.

Although not shown, the handle 2 and the drive shaft 6 are connected via an overload prevention device, and when an excessive load acts on the handle 2, the handle 2 is moved relative to the drive shaft 5. And idle.

As described above, according to the present invention, the pin gear for meshing with the pin 33a of the rack bar 33 supporting the door in accordance with the magnitude of the input from the handle 2 is provided. Is driven auxiliary, and the door is driven up and down with relatively little effort. The electric power to the motor 3 of the auxiliary driving device is supplied to the battery 5 installed on the main body A of the elevating device.
1, the battery 51 is charged by electricity generated by a solar panel 50 provided around the battery 51. Therefore, the door lifting device is always maintained in a state where it can be easily operated with a small amount of labor.

Further, since the solar panel 50 covers the upper projecting space of the rack bar 33 and also serves as a storage cover for the battery 51, the space is not wasted and the surrounding scenery is not damaged.

In the above embodiment, as a preferred embodiment of the present invention, the door lifting / lowering device provided with the auxiliary driving device driven by relatively small electric power has been described. The device has an internal battery 5 so that it can be installed in non-electrified areas where power lines cannot be drawn.
1, and the rack bar 33 may be configured to be driven up and down only by a driving device (not shown) having a motor.

Further, in the illustrated embodiment, the battery 5 is formed by four side solar panels 50 arranged in a square tubular shape.
1 and an example in which the projecting space of the rack bar 33 is shown,
In the door lifting device according to the present invention, the solar panel 50 surrounds the projecting space of the rack bar 33 like a rack cover, and has a battery 51 connected to the solar panel 50 inside.
The solar panel 50 may be arranged in a polygonal cylindrical shape such as a triangular cylinder or a pentagonal cylinder, or may be curved itself and arranged in a cylindrical shape. Is also good.
