Description

Technical Field

[0001] This invention relates to the field of bin racking technology, and in particular to an adjustable crossbeam bin rack. Background Technology

[0002] Beam racking is a professional storage rack designed for storing and retrieving goods from storage bins. It mainly consists of uprights and beams on the outer side. While its structure is simple and sturdy, it relies heavily on bottom beams for support, requiring a large number of beams to ensure bin stability. Furthermore, it cannot create effective limiting structures at the bottom of the bins, resulting in limited safety. Additionally, it can cause significant operational difficulties when the bins are heavily loaded with material during loading and unloading. Summary of the Invention

[0003] The technical problem that this invention aims to solve is that current crossbeam racks rely solely on bottom beams for support, requiring the installation of a large number of beams to ensure the stability of the material bins. Furthermore, they cannot form an effective limiting structure at the bottom of the material bins as needed, resulting in limited safety. Moreover, if the material bins are filled with a large amount of material during loading and unloading, it can lead to very difficult operation.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a cross-beam adjustable bin rack, including a main rack, the main rack including a longitudinal support frame and a horizontal placement frame fixed inside the longitudinal support frame, the upper end of the inner side of the horizontal placement frame is symmetrically provided with lateral assembly slots, the horizontal placement frame is provided with a horizontal support square tube for supporting goods inside the horizontal support square tube, a flip-type lateral support frame is installed inside the horizontal support square tube, an internal adjustment device for controlling the flip-type lateral support frame is movably assembled on one side inside the horizontal support square tube, and a lifting adjustment component is installed on the outer side of the flip-type lateral support frame.

[0005] The horizontal support square tube has lateral limiting assembly frames on both sides that are axially fixed and cooperate with the lateral assembly slots. The horizontal support square tube is inserted into the lateral assembly slots through the lateral limiting assembly frames on both sides and is fixedly assembled with the inside of the horizontal placement frame.

[0006] The horizontal support square tube has an internal mounting port with flip-opening ends. A detachable internal assembly tube for assembling a flip-type lateral support frame is installed inside the internal mounting port.

[0007] The flip-type lateral support frame includes an external adjusting tube that is movably sleeved on the outside of the detachable internal assembly tube, an inclined connecting bracket fixed on the outer arc surface of the external adjusting tube, and a lateral support plate fixed on the outside of the inclined connecting bracket.

[0008] The internal adjustment device includes an integral lateral adjustment worm gear fixed to the outer side of the external adjustment tube and a transverse adjustment worm gear that drives the lateral adjustment worm gear.

[0009] The lifting adjustment assembly includes an internal control guide rail welded and fixed to the outer side of the lateral support plate, a lateral adjustment screw movably assembled inside the internal control guide rail, a lateral support limiting plate with internal thread lifting blocks on both sides, a transverse linkage shaft laterally assembled inside the internal control guide rail, and a transmission gear set for driving the lateral adjustment screw and the transverse linkage shaft. The lateral support limiting plate is threaded onto the outer side of the lateral adjustment screw through internal thread lifting blocks.

[0010] The upper end of the lateral support limiting plate is provided with a serrated limiting groove.

[0011] The upper surface of the horizontally placed support square tube is provided with an upper and lower sinking groove, and an electrically controlled extrusion and lifting mechanism is provided inside the upper and lower sinking groove.

[0012] The electrically controlled extrusion lifting mechanism includes an inner linkage rod movably assembled inside the upper sinking trough, an inner extrusion rod movably connected to the inner linkage rod, an electric drive wheel installed between the inner linkage rod and the inner extrusion rod, and an inner extrusion support rod fixed inside the blind hole installed inside the upper sinking trough.

[0013] The lower end of the horizontal placement frame is located below the side assembly slot, where the lower assembly plate of the external installation control panel is fixedly assembled.

[0014] The beneficial effects of this invention are:

[0015] (1) The adjustable crossbeam bin rack of the present invention adopts a detachable structural design, which can freely change the installation position and quantity of the horizontal support square tubes as needed, making it more convenient to use;

[0016] (2) The horizontal support square tube is fixedly assembled by inserting the lateral limiting assembly frames on both sides into the lateral assembly slots and the inner side of the horizontal placement frame, which greatly improves the structural firmness and stability after installation.

[0017] (3) A flip-type lateral support frame is installed inside the horizontal support square tube. The flip-type lateral support frame is controlled by the internal adjustment device inside the horizontal support square tube, which can increase the support area of ​​the horizontal support square tube and greatly reduce the number of horizontal support square tubes installed.

[0018] (4) By using the lifting adjustment component on the outer side of the flip-type lateral support frame, a lateral limiting mechanism can be formed on one side of the flip-type lateral support frame as needed, which can laterally limit the material box placed on the shelf, thereby improving stability and limiting ability.

[0019] (5) The entire flip-type lateral support frame can be directly attached to the outside of the horizontal support square tube when idle, without taking up too much space. The overall structure is compact and the unfolding and closing operation is simple and convenient.

[0020] (6) The flip-type side support frame adopts a detachable structure design, which facilitates later maintenance and replacement and reduces the cost of use. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] Figure 1 , Figure 2 , Figure 3 and Figure 4 The illustrated adjustable crossbeam shelving includes a main shelving unit, which includes a longitudinal support frame 1 and a transverse placement frame 2 fixed inside the longitudinal support frame 1. The transverse placement frame 2 has symmetrically arranged lateral assembly slots 3 on the upper end of its inner side. The transverse placement frame 2 is provided with a transverse support square tube 4 for supporting goods. A flip-type lateral support frame 5 is installed inside the transverse support square tube 4. An internal adjustment device 6 for controlling the flip-type lateral support frame 5 is movably installed on one side of the transverse support square tube 4. A lifting adjustment component 7 is installed on the outer side of the flip-type lateral support frame 5.

[0029] To facilitate lateral assembly, the horizontal support square tube 4 has lateral limiting assembly frames 8 on both sides that are axially fixed and cooperate with the lateral assembly slots 3. The horizontal support square tube 4 is inserted into the lateral assembly slots 3 through the lateral limiting assembly frames 8 on both sides and is fixedly assembled with the inside of the horizontal placement frame 2.

[0030] To facilitate loading and unloading, an internal mounting port 9 with flip-opening ends is opened inside the horizontal support square tube 4. A detachable internal mounting tube 10 for assembling the flip-type lateral support frame 5 is installed inside the internal mounting port 9.

[0031] The upper end of the horizontal support square tube 4 is provided with an upper mounting through hole that communicates with the internal mounting port 9. The inner bottom surface of the internal mounting port 9 is provided with an internal threaded mounting hole for easy threaded fixing of the detachable internal assembly tube 10. The detachable internal assembly tube 10 is screwed into the internal threaded mounting hole through the external threaded tube of the integrated structure at the bottom to be fixedly assembled with the horizontal support square tube 4.

[0032] For easy adjustment, the flip-type lateral support frame 5 includes an external adjustment tube 51 that is movably sleeved on the outside of the detachable internal assembly tube 10, an inclined connecting bracket 52 fixed on the outer arc surface of the external adjustment tube 51, and a lateral support plate 53 fixed on the outside of the inclined connecting bracket 52.

[0033] To facilitate the adjustment and flipping, the internal adjustment device 6 includes an integral lateral adjustment worm gear 61 fixed to the outer side of the external adjustment tube 51 and a transverse adjustment worm 62 that drives the lateral adjustment worm gear 61.

[0034] The lower end of the horizontal support square tube 4 is provided with a bottom adjustment slot at one end of the horizontal adjustment worm 62. By rotating the hexagonal control head at one end of the horizontal adjustment worm 62, the horizontal adjustment worm 62 can be rotated, thereby adjusting the angle of the lateral adjustment worm wheel 61, which in turn rotates the external adjustment tube 51, causing the inclined connecting bracket 52 and the lateral support plate 53 fixed on the outside of the inclined connecting bracket 52 to flip.

[0035] To facilitate lifting and adjusting, the lifting and adjusting assembly 7 includes an internal control rail 71 welded and fixed to the outer side of the lateral support plate 53, a lateral adjusting screw 72 movably mounted inside the internal control rail 71, a lateral support limiting plate 74 with internally threaded lifting blocks 73 on both sides, a transverse linkage shaft 75 laterally mounted inside the internal control rail 71, and a transmission gear set 76 for driving the lateral adjusting screw 72 and the transverse linkage shaft 75. The lateral support limiting plate 74 is threaded onto the outer side of the lateral adjusting screw 72 through the internally threaded lifting blocks 73.

[0036] The transmission gear set 76 includes a first bevel gear axially fixed to the bottom of the lateral adjusting screw 72 and a second bevel gear axially fixed to both sides of the transverse linkage shaft 75. The transverse linkage shaft 75 meshes with the first bevel gears at the bottom of the lateral adjusting screw 72 on both sides through the second bevel gears on both sides. By rotating the transverse linkage shaft 75, the rotation of the lateral adjusting screw 72 on both sides can be controlled synchronously, thereby adjusting the height of the internal thread lifting block 73 and the entire lateral support limiting plate 74.

[0037] To improve surface anti-slip properties, a serrated limiting groove 77 is provided on the upper end of the lateral support limiting plate 74.

[0038] To facilitate top storage and control of lifting and compression, an upper recessed groove is provided on the upper surface of the horizontal support square tube 4, and an electrically controlled compression and lifting mechanism 11 is installed inside the upper recessed groove.

[0039] To facilitate loading and unloading of materials, the electrically controlled extrusion lifting mechanism 11 includes an inner linkage rod 111 movably mounted inside the upper sinking trough, an inner extrusion rod 112 movably connected to the inner linkage rod 111, an electric drive wheel 113 installed between the inner linkage rod 111 and the inner extrusion rod 112, and an inner extrusion support rod 114 fixed inside the blind hole on the inner side of the upper sinking trough.

[0040] Both the electric drive wheel 113 and the inner extrusion support rod 114 are existing technologies. The electric drive wheel 113 is raised to contact the bottom of the material box, and then rotates to drive the loading and unloading of the material box, reducing the difficulty of operation. The inner extrusion support rod 114 extends to extrude the inner extrusion rod 112, and the inner extrusion rod 112 extrudes the inner linkage rod 111, thereby controlling the lifting and lowering of the electric drive wheel 113. One side of the inner linkage rod 111 is movably mounted inside the upper sinking groove through a horizontal mounting shaft, and the other side of the inner linkage rod 111 is movably connected to the inner extrusion rod 112. One end of the inner extrusion rod 112 is movably connected to the inner linkage rod 111, and the other side of the inner extrusion rod 112 is movably connected to the telescopic section of the inner extrusion support rod 114. The electric drive wheel 113 is movably installed inside the connecting end of the inner extrusion rod 112, while the inner linkage rod 111 is movably installed outside the connecting end of the inner extrusion rod 112.

[0041] To facilitate lateral control, the lower end of the horizontal placement frame 2 is located below the lateral assembly slot 3 to fix and assemble the lower assembly plate 13 of the external installation control panel 12.

[0042] A power supply terminal is installed on the bottom surface of the side mounting slot 3. The electric drive wheel 113 and the inner extrusion strut 114 are powered by a low-voltage DC circuit installed inside the horizontal placement frame 2. The electric drive wheel 113 and the inner extrusion strut 114 are controlled by the control panel 12 of the prior art.

[0043] The adjustment principle is as follows: The material box is placed on the horizontal support square tube 4. Then, by pressing the switch on the control panel 12, the electric drive wheel 113 is controlled to contact the bottom of the material box. The electric drive wheel 113 rotates, thus conveying the material box inwards to the designated position. The electric drive wheel 113 then descends, and the bottom of the material box contacts the upper surface of the horizontal support square tube 4, improving stability. After adjustment, the internal adjustment devices 6 at the front and rear ends of the material box are controlled to flip laterally, and the lifting adjustment assembly 7 is then raised to limit the front and rear ends of the material box. Meanwhile, the internal adjustment devices 6 on both sides of the horizontal support square tube 4 at the bottom of the material box flip laterally, increasing the bottom support area. The internal adjustment devices 6 on both sides of the horizontal support square tube 4 do not flip; instead, the lifting adjustment assembly 7 is directly raised, thus limiting the movement on both sides.

[0044] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
