Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fireproof panel closing device for preventing a fire from spreading when a fire occurs.

[0002]

[Prior art]

 Conventionally, a fireproof panel closing device consists of a panel, a wire winding mechanism, a fuse interlocking closure and a fuse interlocking equipment, and the panel is set in an open state.

When a fire occurs, the fuse sensor melts down due to the temperature of the flame, and the fuse sensor of the fuse interlocking device and the fuse interlocking device (hereinafter referred to as “automatic closing device”) melts down and closes due to the weight of the panel. It is a mechanism.

[0004]

[Problems to be solved by the device]

 In such a conventional fireproof panel closing device, the wire winding mechanism and the automatic closing device are formed as separate mechanisms. Therefore, maintenance work and adjustment work such as position adjustment require skill.

In addition, since the mechanism for winding up the wire for pulling up the panel does not always have a reverse rotation preventing function, the work of winding up and fixing the wire or setting the sensor / fuse in the automatic occluder supporting the panel is performed. Work separately at the same time, and thus requires multiple workers.

When the sensor and fuse are set on the automatic occluder that supports the panel, the wire is free. However, the wire is hidden behind the panel, and the wire is loosened too much and the wire comes off the drum or pulley. There are some things that cannot be discovered even if problems occur.

When such a trouble occurs, the purpose of the device may not be achieved when a fire occurs. Also, when performing maintenance work, the automatic closure is opened, the sensor / fuse is removed, or the fuse is blown to check the panel closure, but all require multiple workers.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention uses a wire winding drum that incorporates a wire winding gear and a reverse rotation preventing ratchet pawl in a fire protection panel closing device, and a fuse bracket that interlocks with this is newly constructed, and a fuse sensor Was incorporated.

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view and a partial sectional view of a fireproof panel closing device according to the present invention. Fig. 2 is a fire panel closing device according to the present invention, a plane during operation, and a partial sectional view. FIG. 3 is a plan view and a partial sectional view of a conventional fireproof panel closing device.

FIG. 4 is a front and partial cross-sectional view showing the entire fireproof panel provided with the fireproof panel closing device of the present invention during operation or before being set. FIG. 5 is a front and partial cross-sectional view showing the setting of the entire fire protection panel equipped with the fire protection panel closing device of the present invention. FIG. 6 is a front and partial cross-sectional view showing the setting of the entire fire prevention panel provided with a conventional fire prevention panel closing device.

The operation procedure of the conventional fire protection panel P will be described with reference to FIGS. 3 and 6. FIG. 6 is a view showing a case where the fireproof panel is set, and the device storage case DK of the fireproof panel P is provided with a fireproof panel closing device D and an automatic closing device H8.

The automatic closing device H8 is divided into a fuse interlocking device and a fuse interlocking device. The fuse interlocking device is formed in the device storage case DK and the fuse interlocking device is formed in the upper part of the lower panel.

A fireproof panel closing device D is configured in the device storage case DK. To pull up and set the panel, insert a handle into the wire winding handle insertion hole D5 and wind up the wire W. The panel is stored in the panel storage portion P5, but if the handle is not fixed, the wire W is opened.

In addition, at the same time as winding the wire W, a plurality of people are required to set the sensor and fuse on the fuse interlocking device that supports the panel and the automatic closure device H8 that is formed separately for the fuse interlocking device. Workers are required.

When the sensor / fuse is set in the automatic occluder H8, the handle is removed from the wire winding handle insertion hole D5 and the wire W is opened to complete the setting, but the wire W is gently opened. Therefore, there is a risk of causing troubles such as disconnection from the wire winding drum D2, the shoji block G1, and the frame block G2.

In the fire protection panel closing device D according to the present invention, a wire winding gear DG and a wire winding drum D2 incorporating a reverse rotation prevention ratchet pawl R are used, and fuse brackets H5 and H6 interlocking with this are newly constructed. , And fuse sensor H was incorporated.

FIG. 1 shows the setting of the fireproof panel closing device D according to the present invention. The fireproof panel closing device D is housed in a device housing case DK. As shown in FIG. 5, in order to pull up and set the panels P2 and P3, the handle is inserted into the wire winding handle insertion hole D5 and the wire W is wound up, so that the panel P1 and the panel P2 fit in the panel receiving portion P5. .

The wire take-up drum D2 takes up the wire W, but after the fuse sensor H is installed through the fuse brackets H5 and H6, the wire W is taken in the direction of the arrow W3 indicating the wire take-up direction. Take it up.

The wire winding gear DG rotates in only one direction while biting the anti-reverse rotation ratchet claw R and winds the wire W, and the setting is completed at the same time when the panels P1 and P2 are accommodated in the panel accommodating portion P5.

Therefore, the wire W is not loosened, and there is no problem that the wire W is detached from the wire winding drum D2, the shoji pulley G1, and the frame pulley G2 as in the conventional product. In addition, since the fuse sensor H can be easily removed by hand, functional tests and maintenance can be easily performed.

The operation procedure will be described with reference to FIGS. 2 and 4. A panel opening PO is formed in the center of the fireproof panel P set as described above, and the purpose is to close this opening PO by the panels P1 and P2 when a fire occurs.

Normally, the wire winding drum D2 of the fire protection panel closing device D winds the wire W, and the wire winding gear DG prevents the reverse rotation by engaging the reverse rotation prevention ratchet pawl R.

The reverse rotation preventing ratchet pawl R is supported by a fuse bracket H5 integrated with the ratchet pawl receiving base RB, and the ratchet pawl pressing spring R5 and the ratchet pawl releasing spring R6 keep the repulsive force by the spring force. A fuse sensor H is attached and fixed via fuse brackets H5 and H6.

When a fire occurs, the fuse sensor H is blown by a flame. When the fuse sensor H is blown, the repulsive force of the spring is restored and the fuse bracket H5 integrated with the ratchet pawl receiving base RB flips back.

When the fuse bracket H5, which is integrated with the ratchet pawl receiving base RB, is flipped back, the reverse rotation prevention ratchet pawl R separates from the wire winding gear DG that has been caught, and when the reverse rotation prevention device is released, the wire winding is stopped. The taking drum D2 releases the wire W, and sends the wire W toward the arrow W3 indicating the wire opening direction.

The wire W sent out is lowered by the weights of the panel P1 and the panel P2 via the shoji block G1 and the frame block G2, and closes the panel opening PO.

[Effect of device]

 In the present invention, a wire take-up drum incorporating a wire take-up gear and a reverse rotation preventing ratchet claw is used in the fireproof panel closing device, and a fuse bracket interlocking with this is newly constructed and a fuse sensor is incorporated. Therefore, the fire panel closing device according to the present invention is simple and easy to handle.

The fireproof panel closing device configured as described above does not need to set an automatic closing device for supporting the panel on the panel as in the conventional case. In addition, since the wire winding mechanism that pulls up the panel has a function to prevent reverse rotation, panel setting work, sensor / fuse mounting work, and adjustment work can be performed in a single operation, which can be done by one person. Became.

Since the wire rewinding mechanism has a function to prevent reverse rotation, loosening of the wire is eliminated, and troubles such as disconnection of the wire from the drum and pulley do not occur, and functional tests and maintenance work can be performed easily. Things became possible.
