Description

Technical Field

[0001] The utility model relates to the field of logistics tracks, in particular to a logistics track for crossing a fire compartment. Background Art

[0002] At present, intelligent track logistics systems are widely used in various general hospitals and the logistics warehousing industry to replace the intelligent automated logistics method of manual item handling. However, the setting of the tracks usually forms an intersection with the normal falling route of the fire shutter, which will affect the normal falling of the fire shutter. Therefore, the tracks here are usually set in a breakable form. In case of a fire, the tracks here are disconnected to enable the normal closing of the fire shutter.

[0003] In the prior art, the utility model patent with the application number CN202011547940.4 discloses an independent fire door crossing track system, which includes a hoisting track. The hoisting track includes a first fixed track, a movable track connected to the first fixed track, and a second fixed track connected to the movable track. The first fixed track and the movable track are connected by an electromagnetic lock, and the movable track and the second fixed track are foldably connected. The movable track is located in the fire door area. When there is a fire alarm, after the electromagnet suction cup is powered off, the compression force of the striker spring will be released, and the locking tongue on the movable track will be pushed out of the locking area. The movable folding track will fall due to its own weight, avoiding the fire door closing area.

[0004] However, the above track system still has the following defects: the movable folding track only rotates downward and opens under the action of its own weight, resulting in a slow opening efficiency of the movable folding track, and the movable folding track will swing back and forth under the action of inertia after opening, affecting the normal closing of the fire door or the fire shutter. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a logistics track for crossing a fire compartment, and the movable section of the logistics track has a higher opening efficiency, so as to solve the defects proposed in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A logistics track crossing a fire compartment, comprising a logistics track body, the logistics track body is provided with a first fixed section and a second fixed section, an active section is connected between the first fixed section and the second fixed section, one end of the active section is fixedly installed with a connecting plate, the connecting plate is hinged on the first fixed section, so that the active section can rotate in a vertical plane, the other end of the active section is connected to the second fixed section through an electromagnetic lock mechanism; a connecting shaft is fixedly installed on the connecting plate, the connecting shaft is parallel to the axis of rotation of the active section, a slide rail is fixedly installed on the first fixed section, a slider is slidably installed on the slide rail, a connecting seat is fixedly installed on the slider, a strip-shaped hole for the connecting shaft to pass through is provided on the connecting seat, when the active section rotates, it drives the slider to move along the slide rail, and a spring is connected between the slide rail and the slider, when the spring extends, it drives the slider to move along the slide rail and makes the active section rotate downward to open.

[0008] As a preferred technical solution, there are two connecting plates, the two connecting plates are respectively fixedly installed on both sides of the active section along the width direction, and the end of the connecting plate extending out of the active section is hinged to the first fixed section.

[0009] As a preferred technical solution, the connecting shaft is fixedly installed between the two connecting plates, and the connecting shaft is located above the first fixed section.

[0010] As a preferred technical solution, a ratchet tooth bar extending in the same direction is fixedly installed on the slide rail, a ratchet pawl matching with the ratchet tooth bar is rotatably installed on the slider, a torsion spring for making the ratchet pawl engage with the ratchet tooth bar is connected between the slider and the ratchet pawl, when the ratchet pawl engages with the ratchet tooth bar, it restricts the active section from rotating upward to close.

[0011] As a preferred technical solution, a lever is provided on the ratchet pawl.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] 1. While the active section rotates downward under the action of gravity, the spring extends and pushes the slider to move leftward along the slide rail, and the slider pushes the active section to rotate downward faster through the connecting seat and the connecting shaft, so that the active section can be quickly opened, and the opening efficiency of the active section is higher;

[0014] 2. When the ratchet pawl engages with the ratchet tooth bar, it restricts the slider from moving rightward along the slide rail, and further makes the active section can only rotate downward to open after the electromagnet is powered off, and cannot rotate upward to close, thus avoiding the active section from swinging back and forth under the action of inertia, and making the closing of the fire shutter smoother.

Specific embodiments

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] Such as Figures 1 to 5As shown in the figure, a logistics track crossing a fire compartment includes a logistics track body. The logistics track body is provided with a first fixed section 1 and a second fixed section 2. The first fixed section 1 and the second fixed section 2 are arranged in a straight line. The first fixed section 1 and the second fixed section 2 are respectively fixedly installed on the ceiling through hanging brackets. An active section 3 is connected between the first fixed section 1 and the second fixed section 2. A fire shutter is arranged above the active section 3. The right end of the active section 3 is fixedly installed with a connecting plate 4. Specifically, there are two connecting plates 4. The two connecting plates 4 are respectively fixedly installed on the front and back sides of the active section 3 through bolts. The connecting plate 4 extends out of the end of the active section 3 to the right and is hinged on the first fixed section 1 through a pin shaft 5. The pin shaft 5 extends back and forth along the width direction of the active section 3, so that the active section 3 can rotate up and down in the vertical plane.

[0024] The left end of the active section 3 is connected to the second fixed section 2 through an electromagnetic lock mechanism 6. Specifically, as Figure 2 shown, the electromagnetic lock mechanism 6 includes a mounting seat 7 fixedly installed on the top of the second fixed section 2 through bolts. A sliding cavity 8 extending horizontally along the length direction of the second fixed section 2 is arranged in the mounting seat 7. An active block 9 is slidably installed in the sliding cavity 8. A plug rod 10 is integrally formed at the right end of the active block 9. A through hole for the plug rod 10 to pass through is arranged on the right side of the mounting seat 7. A fixed block 11 is fixedly installed on the top of the left end of the active section 3 through bolts. A slot 12 for the plug rod 10 to insert is arranged on the fixed block 11. A return spring 13 is sleeved on the plug rod 10 between the active block 9 and the right side wall of the sliding cavity 8. A metal block 14 is fixedly installed on the top of the active block 9 through bolts. A long strip hole 15 for the metal block 14 to pass through is arranged on the top of the mounting seat 7. An electromagnet 16 for adsorbing the metal block 14 is also fixedly installed on the top of the mounting seat 7 on the right side of the long strip hole 15.

[0025] Under normal conditions, the electromagnet 16 is energized and attracts the metal block 14 to keep the plug rod 10 inserted into the slot 12, so that the active section 3 remains horizontal and in a closed state. When a fire occurs, the electromagnet 16 is powered off and stops adsorbing the metal block 14. Thus, the return spring 13 pushes the active block 9 to move leftward and the plug rod 10 disengages from the slot 12. Furthermore, the active section 3 rotates downward under the action of gravity to open, so that the fire shutter can be normally closed.

[0026] In order to improve the opening efficiency of the active section 3, as Figure 3 and Figure 4As shown, the connecting plate 4 extends rightward from the end of the movable section 3 and is inclined upward to the right. A connecting shaft 17 is fixedly installed between the ends of the two connecting plates 4 away from the movable section 3. The connecting shaft 17 is located above the first fixed section 1 and extends forward and backward parallel to the axis of rotation of the movable section 3. The top of the first fixed section 1 is fixedly installed with a slide rail 18 extending in the same direction by bolts. A slider 19 is slidably installed in the slide rail 18. The cross-section of the slide rail 18 is U-shaped. The inner sides of the opposite side walls of the slide rail 18 are respectively provided with ridges extending along its length direction. The slider 19 is provided with grooves matching the ridges, so as to improve the sliding stability of the slider 19; the top of the slider 19 is fixedly installed with a connecting seat 20. The connecting seat 20 is provided with a strip-shaped hole 21 for the connecting shaft 17 to pass through. When the movable section 3 rotates, it can drive the connecting shaft 17 to move vertically along the strip-shaped hole 21. At the same time, when the movable section 3 rotates, it drives the slider 19 to move along the slide rail 18 through the connecting seat 20. The right end of the slide rail 18 is fixedly installed with a support plate 22 by bolts. A spring 23 is connected between the support plate 22 and the slider 19. When the spring 23 extends, it drives the slider 19 to move leftward along the slide rail 18 and makes the movable section 3 rotate downward to open.

[0027] Specifically, when the electromagnet 16 is powered off and stops adsorbing the metal block 14, the movable section 3 rotates downward to open under the action of gravity; at the same time, the spring 23 extends and pushes the slider 19 to move leftward along the slide rail 18. The slider 19 pushes the movable section 3 to rotate downward faster through the connecting seat 20 and the connecting shaft 17, so that the movable section 3 can be quickly opened.

[0028] A gap is left between the bottom of the slider 19 and the bottom wall of the slide rail 18. The inner side of the bottom wall of the slide rail 18 is fixedly installed with a ratchet rack 24 extending in the same direction by bolts. The slider 19 is provided with a through slot vertically penetrating. A ratchet pawl 25 matching the ratchet rack 24 is arranged in the through slot. A shaft rod 26 extending forward and backward in the width direction of the first fixed section 1 is embedded on the ratchet pawl 25. The shaft rod 26 is rotatably installed on the inner wall of the through slot. A torsion spring 27 for engaging the ratchet pawl 25 with the ratchet rack 24 is sleeved on the shaft rod 26. As Figure 5 shown, one end of the torsion spring 27 abuts against one side of the ratchet pawl 25, and the other end abuts against the top of the slider 19. When the ratchet pawl 25 engages with the ratchet rack 24, it restricts the upward rotation and closing of the movable section 3.

[0029] Specifically, when the ratchet pawl 25 engages with the ratchet rack 24, it restricts the slider from moving rightward along the slide rail 18. Furthermore, after the electromagnet 16 is powered off, the movable section 3 can only rotate downward to open and cannot rotate upward to close, thus avoiding the back-and-forth swing of the movable section 3 under the action of inertia and making the closing of the fire shutter smoother.

[0030] In order to conveniently return the slider 19 to its original position, a lever 28 for conveniently driving its rotation is integrally formed on the top of the ratchet pawl 25.

[0031] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
