Description

Technical Field

[0001] This utility model relates to the field of mezzanine load-bearing technology, and in particular to an integrated mezzanine load-bearing structure. Background Technology

[0002] Integrated racking mezzanine load-bearing structures are space optimization designs that combine racking systems with mezzanine platforms, primarily used in warehousing, logistics, and production scenarios. Their core feature is the use of racking to support the mezzanine platform, fully utilizing vertical space to create additional storage or operational areas within warehouses or factories, while maintaining structural stability and load-bearing capacity. Integrated racking mezzanine load-bearing structures offer an efficient and flexible space optimization solution, particularly suitable for locations with limited space but requiring increased storage or operational areas.

[0003] Existing integrated mezzanine racking structures are typically installed inside factory buildings. To maximize storage space, these structures are often two-story, increasing storage capacity and improving the safety and accessibility of goods. However, the loading and unloading ports on the second floor are usually fixed and open. This makes it easy for workers to slip and fall from the second floor after unloading goods, posing a significant safety hazard. Therefore, we offer an integrated mezzanine racking structure.

The infrared sensor is electrically connected to the control module.

[0033] Reference Figure 2-3 The main body 5 of the load-bearing device is equipped with a support plate 6 inside, and the top two sides of the support plate 6 are equipped with guard plates 7. The support plate 6 and the guard plates 7 are fixed together.

[0034] Four guide sliders 8 are symmetrically arranged at both ends of the support plate 6. Guide grooves 9 are opened on both sides of the main body 5 of the load-bearing device corresponding to the positions of the four guide sliders 8. The guide sliders 8 are slidably connected to the guide grooves 9.

[0035] The top four corners of the main body 5 of the load-bearing device are symmetrically provided with a first roller 11, a second roller 12, a third roller 13 and a fourth roller 14. The top of the main body 5 of the load-bearing device is provided with through grooves at the bottom positions of the first roller 11, the second roller 12, the third roller 13 and the fourth roller 14.

[0036] Cables are wound around the outside of the first roller 11, the second roller 12, the third roller 13 and the fourth roller 14. The bottom ends of the first roller 11, the second roller 12, the third roller 13 and the fourth roller 14 are fixedly connected to the four corners of the support plate 6 through cables. The top of the load-bearing device body 5 is located between the first roller 11 and the second roller 12 and is fixedly connected to the drive motor 10 by bolts.

One end of the third roller 13 is fixedly connected to the fourth roller 14 through the transmission rod 15.

[0038] In this utility model, the supporting base frame 2 provides support for the main body 1 of the load-bearing loft. The ladder 4 at the front end of the main body 1 allows workers to ascend and descend. The guardrails 3 on the top perimeter of the main body 1 prevent falls and improve safety. Goods to be stored are pushed onto the support plate 6 at the bottom of the main body 5 of the load-bearing device. The guardrails 7 on both sides of the support plate 6 further enhance safety during lifting and lowering of goods. The drive motor 10 is activated, simultaneously rotating the first roller 11 and the second roller 12. The rotation of the second roller 12 drives the first sprocket 16 to rotate. The rotation of the first sprocket 16, via the transmission chain 17, drives the second sprocket 18 to rotate. The rotation of the second sprocket 18 drives the third roller 13 to rotate. The rotation of the third roller 13, via the transmission rod 15, drives the fourth roller. When roller 14 rotates, the first roller 11, the second roller 12, the third roller 13, and the fourth roller 14 rotate simultaneously, driving the cable upward to pull the support plate 6. The support plate 6 is guided upward by the guide sliders 8 and guide grooves 9 set on both sides. The support plate 6 can lift the goods to be stored to the second floor of the load-bearing loft body 1. The drive motor 10 drives the first roller 11 and the second roller 12 to reverse. The reverse rotation of the second roller 12 drives the transmission chain 17 and the second sprocket 18 through the first sprocket 16 to drive the third roller 13 to reverse. The reverse rotation of the third roller 13 drives the fourth roller 14 to reverse through the transmission rod 15. The first roller 11, the second roller 12, the third roller 13, and the fourth roller simultaneously flip and release the cable downward. The cable moves downward to the first floor by the self-weight of the support plate 6, guided by the guide grooves 9 and guide sliders 8.

[0039] Reference Figure 1-4 A hydraulic cylinder 19 is fixed to the top of the inner side of the load-bearing device body 5 by bolts. A movable seat 20 is fixedly connected to the output end of the hydraulic cylinder 19. A T-shaped slider 21 is provided on the top of the movable seat 20. A T-shaped groove 22 is provided on the top of the inner side of the load-bearing device body 5 corresponding to the position of the T-shaped slider 21.

[0040] The T-shaped slider 21 is slidably connected to the T-shaped groove 22. Two movable support rods 23 are symmetrically arranged on the top of the movable seat 20. One end of each of the two movable support rods 23 is movably connected to the two sides of the movable seat 20.

[0041] Two opening and closing doors 24 are symmetrically arranged on the top front side of the main body 5 of the load-bearing device. The two sides of the two opening and closing doors 24 are movably connected to the top sides of the main body 5 of the load-bearing device. The ends of the two movable support rods 23 away from the movable seat 20 are movably connected to the inner sides of the two opening and closing doors 24.

[0042] A fixing frame 25 is provided in the middle of both sides of the main body 5 of the load-bearing device. Both ends of the fixing frame 25 are fixedly connected to the main body 5 of the load-bearing device. Through-beam photoelectric sensors are provided on the inner side of the fixing frames 25 on both sides of the main body 5 of the load-bearing device. The photoelectric sensors and infrared sensors are electrically connected to the control module at the same time, and the infrared sensors have priority. The control module can control the hydraulic cylinder 19 to switch through the solenoid valve. The photoelectric sensors are symmetrically arranged on the inner side of the fixing frames 25 on both sides of the main body 5 of the load-bearing device. The through-beam photoelectric sensors are of model ML100.

[0043] In this invention, the support plate 6 and the side guard plates 7 move the goods upward through the fixed frame 25. The upward movement of the goods and support plate 6 interrupts the signal reception of the through-beam photoelectric sensor. The photoelectric sensor transmits the signal to the control template, which opens the solenoid valve, causing the hydraulic cylinder 19 to push the telescopic end outward. The hydraulic cylinder 19 pushes the movable seat 20 to move. The movable seat 20 moves forward guided by the T-shaped slider 21 and T-shaped groove 22. The forward movement of the movable seat 20 pushes the movable support rods 23 on both sides. The forward movement of the movable support rods 23 pushes the opening and closing doors 24 provided on both sides of the front end of the load-bearing device body 5. The opening and closing doors 24 are opened outward by rotating through the movable connection with the load-bearing device body 5. At the same time, since the infrared sensor takes precedence over the photoelectric sensor, the load passes through first. The infrared sensor at the front of the main body 5 detects whether there is anyone outside the opening and closing door and transmits the signal to the control module. After confirming that no one is there, the opening and closing door will automatically open, avoiding injury to people outside the door due to automatic opening and closing. Goods inside the main body 5 can be moved to the second floor of the main body 1 for storage. When the support plate 6 descends, the photoelectric sensor resumes receiving the signal and controls the extension end of the hydraulic cylinder 19 to retract. The hydraulic cylinder 19 drives the movable seat 20 to move inward through the T-shaped slider 21 and T-shaped slide 22. The movable seat 20 drives the movable support rods 23 on both sides to pull the opening and closing door 24. By closing the opening and closing door 24, the second floor of the main body 5 is sealed off, preventing workers from stepping into the gap and falling from the top of the main body 5, thus improving the safety of the device.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
