Description

Technical Field

[0001] This invention relates to the field of logistics warehousing equipment technology, and in particular to a prefabricated logistics warehousing rack. Background Technology

[0002] Prefabricated logistics storage racks are storage equipment with modular design as the core, assembled by splicing standardized components. They are widely used in modern logistics, e-commerce, manufacturing and other fields.

[0003] Currently, the mainstream prefabricated logistics storage racks are mainly bolted assembly types. Specifically, bolts are used to assemble components such as uprights, beams, and struts one by one. Although they have a certain degree of adjustability, the installation process of existing bolted assembly storage racks is cumbersome. Each connection node needs to be bolted individually, and multiple components need to be positioned and fixed one by one, which reduces the overall assembly efficiency of the storage racks. Furthermore, existing storage racks only support goods on each layer through a few beams. When supporting heavy goods for a long time, the load stress is prone to concentration in the middle of the beams, causing the beams to bend downwards. This increases the risk of the racks tipping over and reduces the stability and service life of the racks.

[0004] Therefore, there is an urgent need to provide a prefabricated logistics storage rack that can improve assembly efficiency and operational stability. Summary of the Invention

[0005] Therefore, it is necessary to provide a prefabricated logistics storage rack designed to solve the problems of low assembly efficiency and low stability in use of existing storage racks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated logistics storage rack, comprising: a support unit, wherein multiple support units are arranged linearly and evenly, the support unit comprising two support frame groups symmetrically distributed front and back, and multiple inner support parts are connected between the two support frame groups, and each inner support part is connected to a limit part on its upper and lower sides.

[0007] Each support frame assembly consists of multiple support frames that are evenly distributed from top to bottom and interlocked with each other.

[0008] The limiting part includes two limiting plates symmetrically distributed front and back and located at the splicing of two support frames. Multiple plug-in rods are installed on the opposite ends of the two limiting plates.

[0009] The prefabricated logistics storage rack also includes a support unit. The support unit is arranged in multiple groups and is located between multiple support units. Each support unit consists of multiple support units evenly distributed from top to bottom. The support unit includes a support frame set at the splicing point of the corresponding support frame. The support frame has a rectangular structure. Each of the four corners of the support frame is equipped with a splicing frame that is inserted and matched with the support frame at the corresponding position. The front end of the support frame is connected to two symmetrically distributed diagonal braces.

[0010] The prefabricated logistics storage rack also includes an adjustment unit, which is provided in multiple units and is connected to multiple support frame groups on the front side. The adjustment unit includes multiple lifting parts respectively sleeved on multiple support frames, and the lifting parts are connected to the corresponding diagonal braces.

[0011] The support frame is connected to the four corresponding support frames through four splicing frames. The limiting plate passes through the corresponding inner support, splicing frame and splicing of the upper and lower support frames through multiple plug rods. The lifting part drives the diagonal brace to connect the support frame to the middle of the support frame.

[0012] Preferably, the support unit further includes two connecting baffles that are symmetrically distributed on the left and right and detachably installed at the rear end of the support frame.

[0013] Preferably, the adjustment unit further includes a drive component installed on the corresponding support frame at the lowest side. The drive component is fixedly connected to the lifting part at the lowest side, and a splicing part is detachably installed between two adjacent lifting parts.

[0014] Preferably, the inner support includes an inner support plate with an X-shaped structure, the inner support plate being located between two front and rear support frames at the same height, and connecting plates are installed at all four ends of the inner support plate, with multiple connecting holes provided on the connecting plates.

[0015] Preferably, the limiting part further includes a connecting sleeve disposed between the front and rear support frames, with two sliding rods slidably connected inside the connecting sleeve. The end of the sliding rod away from the connecting sleeve is fixedly connected to the corresponding limiting plate, and two symmetrically distributed limiting holes are opened at the upper end of the sliding rod.

[0016] Preferably, the limiting part further includes four locking holes respectively opened on the upper and lower side walls of the connecting sleeve and symmetrically distributed on the left and right. A locking rod with a U-shaped structure and an opening facing downward is locked in the four locking holes. The two ends of the locking rod are respectively inserted into the corresponding limiting holes on the two sliding rods.

[0017] Preferably, the lifting part includes a lifting frame that is slidably sleeved on the corresponding support frame, a lifting plate is installed at the lower end of the front side wall of the lifting frame, and an installation block is installed at the front end of the lifting frame.

[0018] Preferably, the diagonal brace includes a connector installed at the front end of the support frame, a diagonal brace rod slidably connected to the connector, a waist-shaped hole on the diagonal brace rod, the waist-shaped hole slidingly engaging with the connector, and the end of the diagonal brace rod away from the connector being hinged to the corresponding lifting plate.

[0019] Preferably, the splicing part includes a splicing rod placed between two adjacent mounting blocks, the front end of the splicing rod has a mounting groove, and the upper and lower ends of the splicing rod are detachably installed to the two mounting blocks respectively.

[0020] Preferably, the support frame has a stepped rectangular tubular structure, and multiple evenly distributed insertion holes are provided at both the upper and lower ends of the front and rear side walls of the support frame.

[0021] Preferably, the splicing frame has a U-shaped structure with its opening away from the support frame, and multiple mounting holes are provided on both side walls of the splicing frame.

[0022] Preferably, the support frame has multiple reinforcing bars installed in the middle.

[0023] In summary, the present invention has the following beneficial technical effects: 1. The limiting part adopted in the present invention drives the plug-in rod through the sliding rod, which can simultaneously penetrate the corresponding holes of the support frame, inner support plate and support frame and lock quickly, so as to complete the overall connection of the spliced ​​support frame, inner support plate and support frame in one go, avoiding the tedious process of fixing each component with bolts one by one, and effectively improving the installation and assembly efficiency of the rack.

[0024] 2. The adjustment unit used in this invention drives the lifting frame to rise through the drive component, causing the diagonal brace to change from a horizontal state to an inclined traction state, forming an upward lifting force on the middle of the support frame, improving the integrity of the support unit and the support unit, effectively realizing the transmission of force, offsetting the concentration of bending stress in the middle of the support frame caused by heavy loads, avoiding the deformation of the support frame, thereby improving the stability and service life of the rack, and avoiding the risk of goods tipping over due to the deformation of the support frame in traditional racks.

Detailed Implementation

[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] See Figures 1-3 and Figure 7A prefabricated logistics storage rack includes multiple linearly and evenly distributed support units 1. Each support unit 1 includes two support frame groups symmetrically distributed front and back. Each support frame group consists of multiple support frames 10 evenly distributed from top to bottom and interlocked with each other. The support frame 10 has a stepped rectangular tubular structure. Multiple evenly distributed insertion holes 100 are provided at the upper and lower ends of the front and rear side walls of the support frame 10.

[0037] In the actual work, the installation position is cleaned before the shelving is assembled. Then, the existing bases are installed in the planned position in a symmetrical manner from left to right. Then, multiple support frames 10 are selected, and the large-diameter ends of the multiple support frames 10 are fixed to the multiple bases in sequence by existing bolts or welding to complete the function of limiting and fixing the bottom support frame 10.

[0038] See Figure 1 and Figure 7 The prefabricated logistics storage rack also includes multiple sets of support units 2 located between multiple support units 1. Each set of support units 2 consists of multiple support units 2 evenly distributed from top to bottom. The support unit 2 includes a support frame 20 set at the splicing point of the corresponding support frame 10. The support frame 20 has a rectangular structure and multiple reinforcing rods are installed in the middle of the support frame 20. At each of the four corners of the support frame 20, there is a splicing frame 21 that is inserted and cooperates with the support frame 10 at the corresponding position. The splicing frame 21 has a U-shaped structure and the opening is away from the support frame 20. Multiple mounting holes 210 are opened on both side walls of the splicing frame 21.

[0039] In practice, after the bottom layer of multiple support frames 10 is installed, multiple support brackets 20 are selected and installed sequentially. The support brackets 20 are placed between four adjacent support frames 10. Each support bracket 20 is connected to one of the four corresponding support frames 10 via four splicing frames 21. The splicing frames 21 are tightly fitted to the support frames 10. The positions of the multiple mounting holes 210 on the two side walls of the splicing frames 21 correspond one-to-one with the positions of the multiple insertion holes 100 on the lower side of the support frame 10. Alternatively, support blocks (not shown in the figure) can be installed on the support frames 10 to support the splicing frames 21. As shown, it can be used to initially support and limit the splicing frame 21 and the support frame 20. The reinforcing bar in the middle of the support frame 20 increases the support area of ​​the support frame 20, further strengthens the support strength of the support frame 20, and improves the stability of the support frame 20 itself. The support frame 20 can also limit the four support frames 10 connected to it, improve the bending and tilting resistance of the four support frames 10, and effectively improve the stability of the support frames 10 during use. Repeat this step to place multiple support frames 20 between each of the four adjacent support frames 10.

[0040] See Figure 1 and Figure 7Multiple inner support parts 11 are connected between the two support frame groups. Each inner support part 11 includes an inner support plate 110 with an X-shaped structure. The inner support plate 110 is located between two front and rear support frames 10 at the same height. Each of the four ends of the inner support plate 110 is equipped with a connecting plate 111, and multiple connecting holes 112 are provided on the connecting plate 111.

[0041] In practice, after the multiple support frames 20 at the bottom layer are placed, multiple inner support plates 110 are selected and placed between multiple sets of front and rear support frames 10. The connecting plates 111 at the four ends of the inner support plates 110 are located at the splicing points on the upper and lower sides of the front and rear support frames 10 and are in close contact with the side wall of the corresponding splicing frame 21. The multiple connecting holes 112 on the connecting plates 111 correspond one-to-one with the multiple mounting holes 210.

[0042] See Figure 1 , Figure 7 and Figure 8 Each inner support 11 is connected to a limiting part 12 on both the upper and lower sides. The limiting part 12 includes two limiting plates 120 that are symmetrically distributed front and back and located at the splice of the two support frames 10. Multiple plug-in rods 121 are installed on the opposite ends of the two limiting plates 120.

[0043] See Figure 4 , Figure 5 , Figure 7 and Figure 8 The limiting part 12 also includes a connecting sleeve 122 disposed between the front and rear support frames 10. Two sliding rods 123 are slidably connected inside the connecting sleeve 122. The end of the sliding rod 123 away from the connecting sleeve 122 is fixedly connected to the corresponding limiting plate 120. Two symmetrically distributed limiting holes 124 are opened at the upper end of the sliding rod 123.

[0044] See Figure 4 , Figure 5 , Figure 7 and Figure 8 The limiting part 12 also includes four locking holes 125 respectively opened on the upper and lower side walls of the connecting sleeve 122 and symmetrically distributed on the left and right. The four locking holes 125 are connected together to a locking rod 126 with a U-shaped structure and an opening facing downward. The two ends of the locking rod 126 are respectively inserted into the corresponding limiting holes 124 on the two sliding rods 123.

[0045] In practice, after the inner support plate 110 at the bottom is placed, a limiting part 12 is selected and moved to the lower side between the two support frames 10. Two sliding rods 123 are slid, and the sliding rods 123 slide within the connecting sleeve 122, causing the limiting plate 120 to move towards the corresponding connecting plate 111. The limiting plate 120 simultaneously passes through multiple connecting holes 112 in the corresponding inner support part 11, multiple mounting holes 210 on the splicing frame 21, and multiple insertion holes 100 at the lower splicing point of the support frame 10 via multiple insertion rods 121. At this time, the sliding rod 123 is located in the limiting hole 124 within the connecting sleeve 122, which is in contact with the connecting sleeve 121. The two vertical locking holes 125 on the top are coaxial. The locking rod 126 then passes through the two limiting holes 124 and the four locking holes 125, thus limiting the sliding rod 123. Furthermore, by using multiple insertion rods 121 to feed, the support frame 10, inner support plate 110, and support frame 20 are simultaneously connected as a whole. This effectively reduces the number of steps required for workers to sequentially bolt the support frame 10, inner support plate 110, and support frame 20, improving the efficiency of the prefabricated logistics storage rack installation. After the bottom support frame 10, inner support plate 110, and support frame 20 are connected as a whole, multiple support frames 10 are selected and arranged accordingly. Next, multiple support frames 10 are inserted onto the multiple support frames 10 already installed at the bottom. The large-diameter end of the support frame 10 to be installed is inserted into the small-diameter end of the already installed support frame 10. After insertion, the multiple insertion holes 100 on the lower side of the upper support frame 10 correspond one-to-one with the multiple insertion holes 100 on the upper side of the lower support frame 10. Then, the installation steps of multiple support frames 20 and multiple inner support plates 110 are repeated. At this time, the ends of the two connecting plates 111 at the upper end of the lower inner support plate 110 are attached to the ends of the two connecting plates 111 at the lower end of the upper inner support plate 110 and are located at the splice of the upper and lower support frames 10. Then, the limiting part 12 is used to install the support frames 10. In the step of connecting the inner support plate 110 and the support frame 20 as a whole, the limiting part 12 connects the splicing point of the upper and lower support frames 10, the upper and lower inner support plates 110 and the support frame 20 as a whole, which effectively increases the overall connection strength of the spliced ​​support frame 10 and reduces the operation steps of bolt splicing between the support frames 10, further improving the installation efficiency of the prefabricated logistics storage rack. Repeat this step to splice the support frame 10 to the required height. Multiple limiting parts 12 on the same side further limit the front and rear spliced ​​support frame groups, effectively improving the inward bending strength of the support frame group and further improving the stability of the support frame group in use.

[0046] See Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7The prefabricated logistics storage rack also includes multiple adjustment units 3 that are respectively connected to multiple support frame groups on the front side. Each adjustment unit 3 includes multiple lifting parts 30 respectively sleeved on multiple support frames 10. Each lifting part 30 includes a lifting frame 300 that is slidably sleeved on the corresponding support frame 10. A lifting plate 301 is installed at the lower end of the front side wall of the lifting frame 300, and an installation block 302 is installed at the front end of the lifting frame 300.

[0047] In practice, before installing the support frame 10 located on the front side, the lifting frame 300 is first placed on the support frame 10 located on the front side, and then multiple support frames 10 are spliced ​​and installed.

[0048] See Figure 7 The front end of the support frame 20 is connected to two symmetrically distributed diagonal braces 22. The lifting part 30 is connected to the corresponding diagonal brace 22. The diagonal brace 22 includes a connector 220 installed at the front end of the support frame 20. A diagonal brace 221 is slidably connected to the connector 220. The diagonal brace 221 has a waist-shaped hole, which is slidably engaged with the connector 220. The end of the diagonal brace 221 away from the connector 220 is hinged to the corresponding lifting plate 301.

[0049] In actual operation, after multiple support frames 10 are spliced ​​and installed, multiple diagonal braces 221 are hinged to multiple corresponding lifting plates 301 through existing pins. The waist-shaped hole is used to cooperate with the connector 220 for sliding and rotating of the diagonal braces 221.

[0050] See Figure 1 , Figure 2 , Figure 4 and Figure 7 The adjustment unit 3 also includes a drive component 31 installed on the support frame 10 at the lowest side. The drive component 31 is fixedly connected to the lifting part 30 at the lowest side. A splicing part 32 is detachably installed between two adjacent lifting parts 30. The splicing part 32 includes a splicing rod 320 placed between two adjacent mounting blocks 302. The front end of the splicing rod 320 is provided with a mounting groove 321. The upper and lower ends of the splicing rod 320 are detachably installed to the two mounting blocks 302 by bolts.

[0051] In actual operation, after multiple lifting frames 300 are in the working position, multiple splicing rods 320 are moved to the space between each pair of vertically adjacent mounting blocks 302. Then, the ends of the splicing rods 320 are fixedly connected to the mounting blocks 302 using existing bolts. The lifting part 30 drives the diagonal brace 22 to connect to the middle of the support frame 20 and the support frame 10. The driving component 31 is an existing hydraulic cylinder, or it can be a linear drive device such as a high-torque electric push rod.

[0052] See Figure 1 , Figure 2 and Figure 7 The supporting unit 2 also includes two connecting baffles 23 that are symmetrically distributed on the left and right and detachably installed at the rear end of the supporting frame 20.

[0053] In operation, initially, the lifting frame 300, along with the lifting plate 301, is positioned at the support frame 20. At this point, the multiple diagonal braces 221 are horizontal, not affecting the placement of goods. When the existing forklift places goods on the support frame 20 (which can hold at least two stacks of goods), the drive unit 31 is activated. The drive unit 31 pushes the bottom mounting block 302, causing the corresponding lifting frame 300 to rise. The rising lifting frame 300 then drives one or two diagonal braces 221 to rise. The strut 221 moves and rotates to an inclined state until the lifting frame 300 moves to the designated position. At this time, the end of the slotted hole on the strut 221 is in close contact with the connector 220. The inclined strut 221, in its inclined state, pulls and lifts the middle part of the support frame 20 through the connector 220, so that the support frame 20 is connected to the corresponding support frame 10 as a whole. This effectively realizes the transmission of force on the support frame 20 and avoids stress concentration and bending in the middle of the support frame 20 caused by placing heavy goods on it for a long time. The increased strength of the support frame 20 in supporting goods enhances the stability and lifespan of the shelving, avoiding the risk of goods tipping over due to deformation of the support frame 20, a common problem in traditional shelving. It also limits the horizontal movement of placed goods. To further strengthen the support frame 20, two connecting baffles 23 are bolted to the support frame 20 and two corresponding support frames 10, increasing the overall integrity of the support frame 20 and support frames 10. The connecting baffles 23 also limit the placement of goods, preventing them from exceeding the range of the support frame 20 and ensuring accurate placement. It should be noted that the movement of the diagonal brace 221 is hydraulically driven, resulting in a short movement time that does not affect forklift loading and unloading. Furthermore, after the diagonal brace 221 on the front side of the goods that do not need to be removed moves in conjunction with the diagonal brace 221 on the front side of the goods that need to be removed, the diagonal brace 221 immediately resets after the goods are removed, without affecting the overall connection between the support frame 20 and the support frame 10.

[0054] Furthermore, the terms "first," "second," "number one," and "number two" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," "number one," or "number two" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
