DETAILED DESCRIPTION

[0031] The application provides a kind of three-dimensional warehouse for storing various shape warning signs as shown in Figures 1-12 The warehouse bottom plate 1, the lifting device 2 and the shelf assembly are included, the lifting device 2 and the shelf assembly are located on the warehouse bottom plate 1, and the warehouse bottom plate 1 is a whole concrete terrace.

[0032] The shelf assembly includes small grid shelves 3 and large grid shelves 4, which are arranged side by side along the longitudinal direction of the warehouse, with a lifting channel for the lifting device 2 in the middle. Through the combination of "high density and small unit" of the small grid shelves 3 and "large capacity and wide unit" of the large grid shelves 4, the diversity of size and stacking mode of triangular, circular, rectangular and combined special-shaped warning signs is adapted, and the adaptability of the warehouse to multi-specification and multi-batch warning signs and the space utilization rate are improved.

[0033] In specific arrangement, the lifting device 2 includes a guide frame 6, the bottom end of the guide frame 6 is provided with a moving frame 5, universal wheels are arranged at the four corners of the bottom of the moving frame 5, the universal wheels are provided with brake structures, which facilitate the movement and positioning of the lifting device 2; a load carrier 8 is slidingly arranged on the guide frame 6, the load carrier 8 can reciprocate along the height direction of the guide frame 6, and rollers are arranged on the load carrier 8, which are attached to the guide frame 6 to ensure the smoothness of the upward and downward sliding of the load carrier 8.

[0034] A top column 7 is fixedly connected to the top of the guide frame 6. A guide wheel 29 is installed on the top column 7. A winch 31 is installed on the guide frame 6. A pull rope 30 is wound around the guide wheel 29. One end of the pull rope 30 is connected to the load rack 8, and the other end of the pull rope 30 is connected to the winch 31. The winch 31 is connected to the factory's power supply.

[0035] When the winch 31 rotates forward, it winds up the pull rope 30, causing the rack 8 to move upward along the height direction of the guide frame 6, and the warning signs and goods on the rack 8 move upward; when the winch 31 rotates in reverse, the pull rope 30 is released, and the rack 8 moves downward along the height direction of the guide frame 6 by its own weight, and the warning signs and goods on the rack 8 move downward.

[0036] Considering the lack of protective structure on the lifting device 2, after prolonged and high-frequency use, situations such as the pull rope 30 breaking or the pull rope 30 detaching from the connection point with the rack 8 may occur, posing safety hazards and affecting the efficiency of the automated warehouse. To improve the efficiency of the automated warehouse, a fixing plate 9 is installed at the bottom of the rack 8, and two fixing plates 9 can be provided. The two fixing plates 9 are distributed on both sides of the bottom of the rack 8, and a fixing shaft 10 is fixed at the far end of each fixing plate 9. A rotating plate 11 rotates on the fixing shaft 10, and a torsion spring 28 is fitted on the fixing shaft 10. One end of the torsion spring 28 is fixedly connected to the rotating plate 11, and the other end of the torsion spring 28 is fixedly connected to the fixing shaft 10. When the rotating plate 11 is not subjected to other external forces, it remains horizontal due to the elastic support force of the torsion spring 28 (refer to...). Figure 11 ).

[0037] To control the flipping direction of the rotating plate 11, the end of the rotating plate 11 near the fixed plate 9 includes an arc portion 12 and a right-angle portion 13, wherein the arc portion 12 is located below the right-angle portion 13.

[0038] Reference Figure 11 As shown, when the rotating plate 11 is in a horizontal state, if the end of the rotating plate 11 away from the fixed plate 9 is subjected to a downward squeezing force, the rotating plate 11 can flip downwards, and after the squeezing force is lost, the restoring force of the torsion spring 28 causes the rotating plate 11 to return to a horizontal state; if the end of the rotating plate 11 away from the fixed plate 9 is subjected to an upward squeezing force, the right angle part 13 directly abuts against the rotating plate 11, and the rotating plate 11 will not flip upwards.

[0039] The curved section 12 and the right-angle section 13 are provided to control the flipping direction of the rotating plate 11.

[0040] To limit the movement of the rack 8 by means of the fixing plate 9, multiple support plates 21 are provided on the side of the fixing plate 9. The multiple support plates 21 are evenly distributed along the height direction of the guide frame 6. A circular groove 35 is provided on the guide frame 6. A slide rod 34 is slidably arranged inside the circular groove 35. A vertical bar 32 is fixedly connected to the slide rod 34. The vertical bar 32 is distributed along the height direction of the guide frame 6. The support plates 21 are fixedly connected to the vertical bar 32.

[0041] The vertical bar 32 moves along the axial direction of the fixed shaft 10, and the slide bar 34 slides adaptively inside the circular groove 35, so that the pallet 21 can be moved at a fixed horizontal height, and multiple pallets 21 are controlled synchronously.

[0042] An electric push rod 33 is fixedly installed on the guide frame 6. A vertical bar 32 is fixedly connected to the telescopic end of the electric push rod 33. The electric push rod 33 is connected to the power supply of the warehouse.

[0043] In actual use, the extension end of the control electric push rod 33 is retracted, which drives the slide rod 34 to retract into the circular groove 35, so that the support plate 21 and the fixed plate 9 are in the same longitudinal plane (see reference). Figure 8 That is, when the rotating plate 11 moves up and down, it can contact the support plate 21; the extension end of the control electric push rod 33 extends, driving the slide rod 34 to slide outward from the circular groove 35, so that the support plate 21 is misaligned with the fixed plate 9, that is, the rotating plate 11 will not contact the support plate 21 when it moves up and down.

[0044] Furthermore, rollers or other structures can be installed at the bottom corners of the pallet 21, and wear-resistant pads or other structures can be installed at the contact points between the rotating plate 11 and the pallet 21 to reduce wear. Adjustments can be made according to specific usage conditions.

[0045] In addition, the vertical bar 32, the sliding bar 34 and other structures are made of high-strength materials, such as stainless steel, to ensure the support strength. Multiple sets of sliding bars 34 and circular grooves 35 can be set, and multiple sliding bars 34 are connected to the vertical bar 32 to ensure the strength of use.

[0046] Specifically, before the goods are lifted, the telescopic end of the control electric push rod 33 is retracted, which drives the slide rod 34 to retract into the circular groove 35, so that the pallet 21 can be in the same longitudinal plane as the fixed plate 9, that is, the rotating plate 11 can contact the pallet 21 when it moves up and down, and prepare for protection.

[0047] The load carrier 8 is driven by the winch 31 to move upward along the height direction of the guide frame 6, and the goods move upward; the fixed plate 9 and the rotating plate 11 move upward synchronously, wherein the rotating plate 11 moves upward starting from the horizontal state, and when the end of the rotating plate 11 far from the fixed plate 9 contacts the bottom end of the supporting plate 21, the rotating plate 11 can adaptively turn downward around the fixed shaft 10 as the load carrier 8 continues to move upward, and when the rotating plate 11 is out of contact with the supporting plate 21, the rotating plate 11 is reset to the horizontal state under the reset elastic force of the torsional spring 28, without affecting the upward movement of the load carrier 8, and sequentially cooperating with other supporting plates 21 according to the above steps, contacting, turning, out of contact, and resetting.

[0048] During the upward movement, the load carrier 8 has goods thereon, the load is large, the falling risk is large, the rotating plate 11 needs to contact the multiple supporting plates 21 one by one, and be ready for emergency at any time, so as to achieve rapid response in case of an emergency.

[0049] If the load carrier 8 breaks the pull rope 30 during the upward movement, the load carrier 8 and the goods fall downward, and since the rotating plate 11 is in the horizontal state and cannot swing upward, the rotating plate 11 and the fixed plate 9 cannot continue to move downward when the rotating plate 11 contacts the nearest supporting plate 21 below, achieving the effect of braking, the load carrier 8 and the goods stop falling downward, protecting the goods and avoiding potential safety hazards.

[0050] After the goods are placed in the small-grid shelves 3 or the large-grid shelves 4 by the operator, before the load carrier 8 moves downward, the extension end of the electric push rod 33 is extended to drive the sliding rod 34 to slide outward from the circular groove 35, so that the supporting plate 21 is staggered with the fixed plate 9, that is, the rotating plate 11 will not contact the supporting plate 21 when moving downward, and there is no goods on the load carrier 8 during the downward movement, so the falling risk is small.

[0051] In actual use, a speed sensor can be installed on the load carrier 8, and a controller can be arranged to be connected between the electric push rod 33 and the speed sensor.

[0052] When the load carrier 8 moves downward, if the pull rope 30 breaks, the load carrier 8 falls, and after the speed sensor detects that the speed exceeds the set threshold value, the information is transmitted to the controller, the controller controls the extension end of the electric push rod 33 to be quickly retracted, so that the supporting plate 21 is in the same longitudinal plane as the fixed plate 9, that is, the rotating plate 11 can contact the supporting plate 21 below when moving downward, and the same effect of braking is achieved. The controller and its control principle are both common existing technologies, and will not be described here.

[0053] When the load carrier 8 moves downward, the supporting plate 21 is staggered with the fixed plate 9, without affecting the downward movement of the fixed plate 9, and the speed sensor cooperates with the electric push rod 33 to perform emergency braking.

[0054] In the stereoscopic warehouse, the goods are mainly lifted and placed on the small grid shelves 3 or large grid shelves 4 by the lifting device 2. When taking goods, the operator uses a ladder to take them in a scattered manner, that is, the lifting device 2 is used for lifting and replenishing goods at a high frequency, and the load is large, and the risk of falling is large. The load carrier 8 is mostly empty and moves downward, only the self-weight of the load carrier 8, and the risk of falling is small. Therefore, during the lifting and replenishing process, emergency preparation is made at any time, and quick response is made; and during the downward movement, the emergency can be performed by relying on the cooperation of the electric push rod 33 and the speed sensor on the premise that the downward movement of the load carrier 8 is not affected.

[0055] In order to ensure the connection strength of the rotating plate 11 and the fixed plate 9 during braking, a sliding channel 14 is formed on the rotating plate 11. The U-shaped frame 15 is slidably arranged in the sliding channel 14. The opening end of the U-shaped frame 15 is close to the fixed plate 9. One end of the U-shaped frame 15 inside the sliding channel 14 is inclinedly arranged, and the top end is inclined away from the fixed plate 9.

[0056] The upper and lower ends of the U-shaped frame 15 are fixedly connected with the limiting rod 16, and the limiting rod 16 is attached to the rotating plate 11. The limiting rod 16 is arranged to ensure the stability of the sliding of the U-shaped frame 15. The limiting rod 16 is made of high-strength material such as stainless steel to ensure the use strength. Meanwhile, the contact position of the limiting rod 16 and the rotating plate 11 can be provided with a ball to ensure the smoothness of the sliding.

[0057] The top end of the supporting plate 21 is provided with a top groove 22. The bottom of the top groove 22 is fixedly connected with a top rod 23, and the top end of the top rod 23 protrudes out of the top groove 22. The top end of the top rod 23 is in abutting cooperation with the inclined surface of the U-shaped frame 15, and the top end of the top rod 23 can be provided with a ball to reduce the friction with the inclined surface of the U-shaped frame 15 and ensure the stable sliding of the U-shaped frame 15.

[0058] The second spring 27 is arranged in the sliding channel 14. One end of the second spring 27 is fixedly connected to the inner wall of the sliding channel 14, and the other end of the second spring 27 is fixedly connected to the U-shaped frame 15. The second spring 27 is arranged for the reset of the U-shaped frame 15.

[0059] In the natural state (not extruded), the U-shaped frame 15 is staggered with the fixed plate 9 and does not contact the fixed plate 9 (refer to the figure shown in Figure 11 ).

[0060] If the load carrier 8 moves upward and the pull rope 30 breaks, the load carrier 8 and the goods fall downward, the fixed plate 9 and the rotating plate 11 move from top to bottom, the top end of the top rod 23 contacts the inclined surface of the U-shaped frame 15, and the U-shaped frame 15 is inclined at one end inside the sliding channel 14 and the top end is inclined away from the fixed plate 9, so that the U-shaped frame 15 moves towards the fixed plate 9, and the upper and lower ends of the U-shaped frame 15 are clamped on the fixed plate 9, at this time the U-shaped frame 15 connects the rotating plate 11 and the fixed plate 9 into a whole, and ensures the support strength of the rotating plate 11 and the fixed plate 9.

[0061] If the top rod 23 is disconnected from the U-shaped frame 15, the reset elastic force of the second spring 27 makes the U-shaped frame 15 move away from the fixed plate 9, and does not affect the turning of the rotating plate 11.

[0062] By arranging the U-shaped frame 15, the top rod 23 and other structures, the rotating plate 11 is connected to the fixed plate 9 into a whole by the movement of the rotating plate 11, the support strength is ensured, the anti-falling efficiency is improved, and the safety performance of the stereoscopic warehouse is ensured.

[0063] The present application arranges the fixed plate 9, the rotating plate 11, the top rod 23 and the U-shaped frame 15 and other structures to achieve the effect of emergency braking, protect the goods, avoid safety hazards, and does not affect the upward and downward movement of the load carrier 8, and can connect the rotating plate 11 and the fixed plate 9 into a whole, and improve the use efficiency of the stereoscopic warehouse.

[0064] The top rod 23 is externally sleeved with the first spring 24, the bottom end of the first spring 24 is fixedly connected to the bottom of the top groove 22, the bottom end of the sliding channel 14 is fixedly connected with the pressing plate 25, the pressing plate 25 is in abutting connection with the first spring 24, the pressing plate 25 is provided with the through slot 26 for inserting the top rod 23, and the first spring 24 is made of strong material and can be recycled into the inside of the top groove 22 when it is completely contracted.

[0065] Meanwhile, considering that the end away from the fixed plate 9 of the rotating plate 11 will contact the first spring 24 during turning, a roller or other structure can be arranged at the end of the rotating plate 11 away from the fixed plate 9 during actual use, so as to reduce the wear between the first spring 24 and the rotating plate 11, ensure stable movement, and the operator can adjust according to the specific use condition during regular maintenance and other operations.

[0066] By arranging the first spring 24, the pressing plate 25 and the through slot 26 and other structures, the fixed plate 9 and the rotating plate 11 move from top to bottom during actual use, the top end of the top rod 23 first passes through the through slot 26 and then contacts the inclined surface of the U-shaped frame 15, the top rod 23, the pressing plate 25 and the through slot 26 cooperate to connect the rotating plate 11 and the fixed plate 21 into a whole, and the stability of the support is ensured.

[0067] At the same time, the pressing plate 25 extrudes the first spring 24 to contract, the first spring 24 is recovered to the inside of the top groove 22, the first spring 24 carries out unloading buffering, and the impact force generated by falling is reduced.

[0068] And the top rod 23 cooperates with the pressing plate 25 and the through groove 26, and plays a role of guiding the first spring 24, so that the first spring 24 stably contracts.

[0069] In addition, the pressing plate 25 limits the U-shaped frame 15, so that when the fixed plate 9 and the rotating plate 11 move from top to bottom, the top end of the top rod 23 can stably contact the inclined surface of the U-shaped frame 15, and will not directly abut against the bottom end of the U-shaped frame 15.

[0070] Considering that the U-shaped frame 15 is mainly connected by the external rotating plate 11 and the fixed plate 9 into a whole, in order to further ensure the stability of the connection of the rotating plate 11 and the fixed plate 9, the horizontal rod 17 is fixedly connected on the inner wall of the U-shaped frame 15, the first hole section 18 is arranged on the fixed shaft 10, the second hole section 19 is arranged on the rotating plate 11, and the third hole section 20 is arranged on the fixed plate 9, and the first hole section 18, the second hole section 19 and the third hole section 20 are sequentially communicated and the horizontal rod 17 is inserted.

[0071] In a natural state (not extruded, etc.), the U-shaped frame 15 is staggered with the fixed plate 9 and will not contact the fixed plate 9 (refer to Figure 11 At this time, the horizontal rod 17 will not extend into the inside of the first hole section 18, and will not affect the turning of the rotating plate 11.

[0072] When the U-shaped frame 15 moves towards the fixed plate 9, the upper and lower ends of the U-shaped frame 15 are clamped on the fixed plate 9, the horizontal rod 17 is sequentially inserted into the first hole section 18, the second hole section 19 and the third hole section 20, so that the rotating plate 11, the fixed shaft 10 and the fixed plate 9 are connected into a whole, and are located inside the rotating plate 11, the fixed shaft 10 and the fixed plate 9, and cooperate with the U-shaped frame 15, and the inside and outside are limited.
