[0002] The conveying line is used for conveying articles over a long distance, and is generally arranged in a supermarket or a clothing factory. The fire management requirement of these relatively closed places is relatively high, and therefore a series of fire-fighting measures need to be taken in these places to deal with fire emergencies. The setting of a fire door is one of the fire-fighting measures, and in these places, a plurality of fire doors are generally required to be set to separate the places by area so as to isolate the spread of fire when a fire breaks out.

[0003] A fireproof emergency side-pull type disconnecting device is disclosed in Chinese patent document (publication number: CN 207986011U). The device can quickly disconnect the part of the guide rail located in the falling track of the fire door, and can maintain the smoothness of the disconnecting device for a long time. The disconnecting device is arranged in the interval between the first driving section and the second driving section of the conveying guide rail, and includes a transition section. One end of the transition section is hinged to the outlet end of the first driving section, and the other end is a free end. A driving mechanism is arranged between the transition section and the first driving section, and is coupled to the side of the transition section to make the other end of the transition section connect or disconnect with the inlet end of the second driving section. The outlet end of the first driving section is higher than the inlet end of the second driving section.

[0004] In this disconnecting device, the other end of the transition rail needs to be connected with the inlet end of the second driving section. However, when the transition rail bridges the interval, it cannot guarantee that the other end of the transition rail is well matched with the second driving section, thereby affecting the smooth passing of the carrier through the transition rail on the conveying line.

[0007] The conveying line is provided with a driving mechanism, and since the fireproof door needs to be lowered at the break position, the driving mechanism needs to terminate on the opposite sides of the break. The carrier can slide through the movable rail by inertia or under the action of gravity. Generally, the carrier slides through the inclined movable rail under the action of gravity.

The fixed plate is fixedly connected to the conveying line, the electric motor and the reversing speed reduction mechanism are fixedly connected through the fixed plate, the structure is simple, and stable driving force can be provided for the movement of the movable rail.

[0014] Compared with the prior art, the utility model has the beneficial effects that: a power mechanism is arranged at one side of the fracture, the movement of the movable rail is driven through the power mechanism, so that the bridging and disconnection of the fracture are realized.

[0020] The fireproof breaking device of the conveying line is arranged on the conveying line, and the structure of the conveying line comprises a track. A driving mechanism is arranged on the outer side of the track in parallel, and the track is arranged in the horizontal direction in the place. In order to separate the area in the place, a plurality of fireproof doors need to be arranged in the place, and the conveying line needs to pass through the position of the fireproof door. In order to separate the area in the place by using the fireproof door, the fireproof door needs to be closed, which requires that a breaking point is arranged on the track to provide the closing position of the fireproof door. In addition, the driving mechanism is also broken, and the driving mechanism is cut off on the outer side of the breaking point.

[0021] The structure of the breaking device comprises a movable track 4, the length of the movable track 4 corresponds to the length of the breaking point, and the movable track 4 is arranged at the position of the breaking point. A position sensor is arranged above the breaking point, and the position sensor is used to sense the position of the fireproof door. A power mechanism is arranged on one side of the track at the breaking point, one end of the movable track 4 is in transmission connection with the power mechanism, and the other end of the movable track 4 is a free end. The position sensor is in electrical connection with the power mechanism. When the position sensor senses that the fireproof door is closed, the power mechanism is started, and the power mechanism drives the movable track 4 to move away from the position of the breaking point. When the fireproof door is opened, the position sensor reversely starts the power mechanism, and the movable track 4 moves to the position of the breaking point and is bridged at the position of the breaking point. A movable limiting piece is arranged on the other side of the track at the breaking point, and the limiting piece is used to support the other end of the movable track 4, so that the movable track 4 is adapted to the running direction of the track. At this time, the movable track 4 is in an inclined position, the inlet end of the movable track 4 is higher than the outlet end, and the carrier slides forward on the movable track 4.

[0022] A pushing mechanism is arranged on the other side of the track at the breaking point, the limiting piece is in transmission connection with the pushing mechanism, and the position sensor is in electrical connection with the pushing mechanism. The pushing mechanism can act before the power mechanism, or due to the speed difference, the position of the limiting piece is first released, so that the movable track 4 smoothly moves under the action of the power mechanism, and the movable track 4 is separated from the position of the breaking point.

[0023] The pushing mechanism comprises a cylinder 5, and the cylinder 5 is arranged in a horizontal manner. The limiting piece is a limiting block 7, and the limiting block 7 is arranged in a horizontal manner. A receiving port is arranged on the other end of the movable track 4 and used to rest on the limiting block 7, so that when the movable track 4 is bridged at the position of the breaking point, the other end of the movable track 4 is lapped on the limiting block 7. An empty port 6 is arranged on the end of the track on the other side of the breaking point, and the limiting block 7 is movably arranged in the empty port 6. Under the action of the cylinder 5, the limiting block 7 can be stretched out to the outer side of the track or retracted into the track to release the position. The cylinder 5 is controlled by a solenoid valve through a gas circuit, and the position sensor is in electrical connection with the solenoid valve. When the position sensor senses that the fireproof door is closed, the limiting block 7 can be quickly retracted into the track under the action of the cylinder 5 through the control of the solenoid valve.

[0024] The power mechanism is an electric motor 1, which is horizontally arranged on a fixed plate 3, and the fixed plate 3 is connected to a support frame of the conveying line through a coupling structure. A reversing speed reduction mechanism 2 is arranged on the fixed plate 3 vertically. The electric motor 1 is drivingly connected to the reversing speed reduction mechanism 2, and a connecting piece 8 is fixedly connected to a power output shaft of the reversing speed reduction mechanism 2. The connecting piece 8 is a curved sheet body, and one end of the movable rail 4 is fixedly connected to the connecting piece 8 through a coupling bolt. A position sensor is arranged outside the power mechanism, and the position sensor is used for sensing the swing position of the connecting piece 8 and is electrically connected to the power mechanism. The movable rail 4 shown in the figure is in a translational mode to realize bridging or disengaging from the break. The movable rail 4 can also realize movement in the vertical direction, but the structure of the power mechanism needs to be adjusted accordingly.

[0025] The fireproof door is generally a rolling shutter door structure, and the position sensor is generally an optical switch. The position sensor is at a certain height from the ground. When the fireproof door is closed, the fireproof door is started to move downward. When the fireproof door reaches the position of the position sensor, the position sensor is triggered, and the position sensor sends a signal to quickly start the cylinder 5 to drive the limit block 7 to quickly retract into the rail. The electric motor 1 is started to move the other end of the movable rail 4 to the outside of the break, and finally leave the break position. The rotation angle of the movable rail 4 is generally 90 degrees or slightly greater than 90 degrees, and the rotation angle of the movable rail 4 is controlled by the position sensor. When the fireproof door rises to the upper side of the position sensor, the cylinder 5 is started, the limit block 7 is extended into the break, and under the action of the electric motor 1, the movable rail 4 swings to the break position. The other end of the movable rail 4 is connected to the limit block 7, and the carrier can normally pass through the movable rail 4.
