Description

TECHNICAL FIELD

[0001] The utility model relates to a conveying line, in particular to a conveying line with emergency disconnecting device. BACKGROUND

[0002] The conveying line is used for conveying articles over a long distance, and is generally arranged in supermarkets and garment factories. Fire management in these relatively closed places has certain requirements, so a series of fire-fighting measures need to be taken in these places to deal with fire emergencies. The setting of fireproof doors as one of the fire-fighting measures requires that multiple fireproof doors be set in these places to separate the places by area to prevent the spread of fire when a fire breaks out. The hanging system is a kind of conveying line used for conveying cloth pieces. In order to meet the requirements of multi-process garment production, the hanging system is generally arranged to be very long. The length of an ordinary single-room factory cannot meet the requirements of setting such a hanging system, so multiple rooms need to be connected in the transverse direction. However, if multiple rooms are connected, some safety hazards may also be caused.

[0003] Chinese patent document (publication number: CN 207986011U) discloses a fireproof emergency side-pull type disconnecting device. The device can quickly disconnect part of the guide rail in the falling track of the fireproof 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. The driving mechanism is coupled to the side of the transition section to connect or disconnect the other end of the transition section to 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 transition section changes its position to connect or disconnect the two driving sections. After the driving sections are disconnected, the transition section needs to be manually lifted to reset it to connect the two driving sections. This is relatively laborious, and the weight of the transition section should not be too large. UTILITY MODEL CONTENTS

The hanger is supported by the indoor roof, and the upper end of the hanger is fixed on the roof. Through the arrangement of the hanger, the setting of the pulling mechanism can be well adapted.

[0011] Further, a cross beam is arranged on the hanger, a plurality of guide wheels are arranged on the cross beam, and the cable abuts against the outer circumferential surface of the guide rail. Through the arrangement of the guide wheels, the cable is arranged conveniently, and the cable accurately exerts force on the lowering rail.

[0012] Further, an electromagnet is arranged corresponding to the position of the lowering rail on the other side of the breakage, and the electromagnet is used to magnetically attract the other end of the lowering rail. The lowering rail can be made of iron, or an iron block is arranged at the other end of the lowering rail to realize the magnetic attraction of the electromagnet, which on one hand facilitates the opposite connection of the other end of the lowering rail with the guide rail, and on the other hand saves labor.

[0013] Further, the lower track is connected with a driving device, the driving device comprises a driving motor and a flexible driving chain which are in transmission connection, and a plurality of driving members extending to the lower track are arranged on the driving chain. By arranging the driving device, the carrier can smoothly pass through the lower track, the lower track can be made longer, and the space requirement of the fireproof door can be well met.

[0014] Further, two parallel lower tracks are arranged at the breaking position, the connecting rod is bridged on the two lower tracks, and the pulling mechanism is in transmission connection with the connecting rod. This makes the emergency breaking device adapt to the hanging system in the clothing field, meets the setting of the long hanging system, and can segment the hanging system.

[0015] Compared with the prior art, the utility model has the beneficial effects that: the pulling mechanism is arranged to apply force to the lower track, the lower track can complete corresponding actions without manpower, and the use convenience is improved.
