Description

Technical Field

[0001] The present invention relates to the technical field of storage racks, and particularly relates to an internal fixed rack, a deployment method and a storage method for a rack stability device. Background Art

[0002] There are generally two ways of matching the hanging pieces and columns of existing edge-of-line racks. One is that the formed hanging claws are inserted into the matching hanging holes, and the other is that screwing is used to replace the cooperation of the hanging claws and hanging holes. However, for edge-of-line racks with any of these fixing principles, the key connecting mating surfaces are on parallel planes. Due to the too small connecting distance of a single anchoring part or the too large fitting clearance, there is a small rotational freedom degree at the connection points as a whole, but it is significantly amplified to the inclination of the frame; (front view of a rectangular frame → front view of a parallelogram)

[0003] At the same time, from the top-down perspective, for the quadrilateral formed by the four vertices of the rack columns, the key connections are arranged on the above-mentioned parallel planes. When an external force acts to make the rack tend to deform into a parallelogram in the area of the top-down rectangular frame, the key connections of the rack resist the external force in a way that is not conducive to load-bearing, resulting in different degrees of parallelogram deformation of the rack; (top-down rectangular frame → top-down parallelogram)

[0004] At the same time, at present, the carrying beam and the hanging piece are connected in a welding form, and its quality is restricted by various factors, resulting in poor consistency of the welding strength at key positions. The positions with poor welding are easily deformed, yield or even break under the action of bending moment, affecting the use safety.

[0005] Generally speaking, the prior art has the following incompatible technical contradictions:

[0006] 1. The fixing method of the key connection restricts the overall anti-inclination rigidity of the frame;

[0007] 2. The difference in the welding quality of the key connection restricts the consistency of the beam strength. Summary of the Invention

[0008] In order to solve the deficiencies in the prior art that the fixing method of the key connection restricts the overall anti-inclination rigidity of the frame and the difference in the welding quality of the key connection restricts the consistency of the beam strength; the present invention provides an internal fixed rack, a deployment method and a storage method for a rack stability device.

[0009] In a first aspect, the present invention provides an internal fixed rack, which includes columns, crossbeams and side beams. The columns, crossbeams and side beams are combined to form a rack, and further includes: at least two crossbeams on at least the same layer form a placement space for storing goods through a first load-bearing wall and a second load-bearing wall; the hanging pieces are installed at the connection parts of the columns with the crossbeams and the side beams.

[0010] Stabilizing device: It includes a tension and compression rod and a connecting plate. The tension and compression rod is connected to the column and / or the cross beam. The fixed wall in the connecting plate is fixed to the wall surface of the column, and the connecting wall in the connecting plate is fixed to the tension and compression rod.

[0011] The tension and compression rod includes at least two tension and compression rod members, and the two tension and compression rod members are nested with each other.

[0012] In a preferred technical solution, an internal fixed shelf further includes a side plate for connecting two of the hanging pieces on the same layer from the side of the shelf. The side plate includes a first side plate wall for connecting the hanging piece and a second side plate wall for blocking the gap between the placement space of the shelf and the end face of the column.

[0013] In a preferred technical solution, the hanging piece includes a first hanging piece wall and a second hanging piece wall. The first hanging piece wall and the second hanging piece wall are respectively provided with a first hanging piece hole group and a second hanging piece hole group. The column is provided with a first column wall and a second column wall. The first column wall and the second column wall are respectively provided with a corresponding first column hole group and a second column hole group. The first hanging piece hole group is correspondingly connected to the first column hole group, and the second hanging piece hole group is correspondingly connected to the second column hole group. After the hanging piece is attached to the column, at least one pair of hole group axes deviates from the axis of the fastener.

[0014] In a preferred technical solution, when the first hanging piece hole group is correspondingly connected to the first column hole group and the second hanging piece hole group is correspondingly connected to the second column hole group, at least one set of the mating connections is a clearance fit at the beginning of fastening and an interference fit at the end of fastening.

[0015] In a preferred technical solution, the hole pitches of the first hanging piece hole group and the first column hole group are different, and the hole pitches of the second hanging piece hole group and the second column hole group are different. The micro degrees of freedom are reduced through the hole pitch and the fitting clearance. The first hanging piece wall abuts against the first column wall. By connecting the first hanging piece hole group to the first column hole group, the degrees of freedom restricted for the first hanging piece wall include X rotation, Z rotation, and Y movement. Due to the existence of a small margin in the connection fit, the degrees of freedom of the first hanging piece wall include X movement, Z movement, and Y rotation. The second hanging piece wall abuts against the second column wall. The second hanging piece hole group is connected to the second column hole group. The degrees of freedom restricted for the second hanging piece wall include X movement, Y rotation, and Z rotation. Due to the existence of a small margin in the connection fit, the degrees of freedom of the second hanging piece wall include Y movement, Z movement, and X rotation.

[0016] By abutting the first hanging piece wall and the second hanging piece wall and connecting the first column wall and the second column wall, the constraints of the two wall surfaces are superimposed and complementary. At the same time, the fitting process of the second hanging piece wall surface causes a slight offset of the center of the first hanging piece hole group on the first hanging piece wall surface from the center of the first column hole group, further strengthening the restriction of the degrees of freedom.

[0017] Preferred technical solution: The crossbeam includes a load-bearing beam, with hanging pieces provided at both ends of the load-bearing beam. The load-bearing beam has a first load-bearing wall and a second load-bearing wall, which are connected. The first load-bearing wall is connected to the second wall of the hanging piece; the first load-bearing wall, the second load-bearing wall, and the hanging piece are integrally formed from the same material.

[0018] Preferred technical solution: The stabilizing device further includes a compensation plate, which is used to compensate for the height deviation between the connection plane of one tension-compression rod and the connection plane of the other tension-compression rod when the tension-compression rod is installed in the shelf plane.

[0019] Preferred technical solution: The stabilizing device further includes a protective pad, which is provided at the contact position between the stabilizing device and the shelf.

[0020] In the second aspect of the present invention, a method for deploying a shelf stabilizing device is as follows:

[0021] Connect the connecting plate according to the fixing requirements of the front view rectangular frame or the top view rectangular frame;

[0022] Match the stable distance L between the head and tail connection positions of the tension-compression rods in the stabilizing device described in the first aspect above;

[0023] Fine-tune the inclination state of the shelf frame corresponding to the fixing surface of the stabilizing device according to the deviation between the stable distance L and the hole distance of the two relatively arranged connecting plates;

[0024] Connect the stabilizing device to the connecting plate;

[0025] Increase support points for strengthening the stability of the compression rod and connecting to the shelf components within the length range of the stabilizing device according to the stable distance L.

[0026] In the third aspect of the present invention, a method for storing a shelf stabilizing device is used to store the stabilizing device described in the first aspect into the shelf.

[0027] Remove the stabilizing device and adjust the tension-compression rod to the contracted state, and store the stabilizing device in the non-material placement area in the contracted state;

[0028] When the stabilizing device in the contracted state is stored at the bottom of the shelf, connect it to the side beams of the two side columns of the shelf through the connection holes provided at the head and tail of the stabilizing device by a flexible connector, ensuring that the stabilizing device does not cause collision or interference with the shelf components during movement in multiple degrees of freedom.

[0029] The beneficial effects achieved by the present invention are:

[0030] 1. By superimposing and restricting degrees of freedom through the connection method of two connecting walls, the mating allowance of the screw holes is effectively eliminated, the degrees of freedom of deflection are effectively restricted, and the anti-tilt ability and overall rigidity of the shelf sorting are significantly improved;

[0031] 2. By the method of continuous material forming, the dependence of part strength on welding strength is eliminated, and the quality consistency of key components is improved;

[0032] 3. The stabilizing device absorbs external forces by being in tension or compression, effectively solving problems such as deformation and structural damage during shelf transportation and movement, and is particularly suitable for line-side shelves with large inertia.

[0033] 4. At the same time, the stabilizing device allows the connection of different shelves or different positions of the same shelf through multi-stage length adjustment.

[0034] 5. When the stabilizing device is not needed, it allows for quick disassembly and storage at the bottom of the shelf.

[0035] 6. Redundant and cumbersome packaging methods such as wooden frames and display boards can be eliminated, improving operation efficiency and reducing packaging and transportation costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] To facilitate those skilled in the art to understand the present invention, the following describes the detailed implementation manners of the present invention with reference to the accompanying drawings.

[0055] Example 1: As Figure 1-18 shown, the present invention provides an internal fixed shelf, including columns 2, crossbeams 3 and side beams 7. The columns 2, crossbeams 3 and side beams 7 are combined to form a shelf 5. At least two crossbeams 3 on at least the same layer form a placement space for storing goods through a first load-bearing wall 311 and a second load-bearing wall 312;

[0056] A hanging piece 1 is installed at the connection part of the column 2 with the crossbeam 3 and the side beam 7;

[0057] A stabilizing device 8: includes a tension-compression rod 81 and a connecting plate 82. The tension-compression rod is connected to the column and / or the crossbeam; The fixed wall 821 in the connecting plate 82 is fixed to the wall surface of the column 2, and the connecting wall 822 in the connecting plate 82 is fixed to the tension-compression rod 81;

[0058] The tension and compression rod 81 includes at least two sections of tension and compression rod members, and the two sections of tension and compression rod members are nested with each other. It should be noted that the upright column 2, the cross beam 3 and the side beam 7 are combined to form a shelf 5. The two ends of the two cross beams 3 are respectively fixed on the corresponding upright columns 2 to form a placement space for storing goods. Correspondingly, the two cross beams 3 must be ensured to be on the same layer (in the same plane) to ensure that the second load-bearing walls of the two cross beams face each other to form a support position for placing items, and the first load-bearing walls of the two cross beams face each other to form a blocking position for restricting or protecting the position of the items. Under the action of the first load-bearing wall and the second load-bearing wall of the cross beam, the items cannot move outward in the direction of the second load-bearing wall in the placement space, ensuring that the shelf will not fall when the shelf tilts or vibrates. Through the hanging piece, the combination of the upright column 2 and the cross beam 3, when an external force acts to make the shelf tend to deform into a parallelogram in the rectangular frame area when viewed from above, the key connections of the shelf resist the external force in a way that is not conducive to loading, so that the shelf shows different degrees of parallelogram deformation.

[0059] Shelves are usually transported to the destination in scattered modules and then assembled on site. After being put into use, fixing measures and other safety measures are usually set and they are no longer moved. However, in some cases, the shelves need to be moved in the final assembled form, such as transportation and in-line operation movement. In these cases where there is movement, there are factors that are not conducive to the structural stability of the shelves. Especially in the working conditions such as violent bumps and sudden braking during transportation, the overall frame of the shelf shakes during these processes, resulting in unstable parallelogram deformation. This unstable deformation will cause excessive stress at the connection nodes between the cross beam and the upright column. Especially under the alternating load of vibration, these local weak positions are very easy to reach the yield limit and deform and break. For shelf equipment with a relatively large specific gravity of the overall weight compared to the overall volume, due to its large inertia, the key connection points are very sensitive to the acceleration applied by the external force to itself.

[0060] In addition, for the transportation process of assembled shelves, the logistics requires packing the shelves with wooden frames. The laying and disassembly of the wooden frames take a long time, it is difficult to move after the wooden frames are erected, and the transportation cost around the wooden frames themselves is relatively high, which increases the logistics cost of the equipment.

[0061] Currently, there is no relatively economical and flexible solution for such mobile scenarios.

[0062] Generally speaking, the following incompatible technical contradictions exist in the prior art:

[0063] 1. The shelf lacks a frame stress absorption device to ensure the equality of the diagonals of its own frame;

[0064] 2. The traditional packaging requirements such as wooden frames and pallets for whole machine transportation restrict the reduction of logistics costs and improvement of efficiency of the equipment;

[0065] Embodiment 2: To address the above problems, when one or more of the stabilizing devices 8 are connected to the upright posts 2 and / or the cross beams 3, they, together with the front-view rectangular frame 5A and / or the top-view rectangular frame 5B of the shelf, form multiple geometric triangles or equivalent geometric triangles.

[0066] When the stabilizing device 8 acts on the front-view rectangular frame 5A, the stabilizing device is connected to the upright posts 2 and / or the cross beams 3 and is arranged in a plane parallel to the front of the shelf frame. Multiple tension-compression rods 81 are connected to the two side upright posts 2 from the rear of the shelf, so that the two side upright posts 2 of the shelf, the cross beams 3 connecting the two side upright posts, and the stabilizing device 8 form a geometric triangle.

[0067] When the stabilizing device 8 acts on the top-view rectangular frame 5B, the stabilizing device 8 is connected to the upright posts 2 and / or the cross beams 3 and is arranged in a plane parallel to the top-view plane of the shelf frame. Multiple tension-compression rods 81 are connected to the diagonal upright posts 2 from the inside of the shelf, so that the diagonal upright posts 2 of the shelf, the side beams 7 of the upright posts, and the stabilizing device 8 form a geometric triangle.

[0068] The stabilizing device 8 includes tension-compression rods. By adjusting the overall length of the tension-compression rods to adapt to the characteristic dimensions of the shelf frame, the connection between the tension-compression rods of the stabilizing device and the upright posts 2 and / or the cross beams 3 of the shelf frame is implemented, so that the shelf frame and the stabilizing device 8 as a whole form multiple geometric triangles, thereby making the structure included in the connection plane where the stabilizing device 8 is located form a geometrically invariant system. The stabilizing device 8 absorbs the internal force of the frame deformation with the dual characteristics of tension and compression; through the tension-compression rods 81 of the stabilizing device, the connection with the upright posts 2 and / or the cross beams 3 is achieved, so as to ensure that when the shelf 5 is subjected to corresponding external forces, it can absorb the corresponding stress to ensure the equality of the diagonal lines of its own frame, thereby improving the stability of the shelf 5; and one adjacent tension-compression rod 81 i and the other tension-compression rod 81 i+1 are nested with each other. For example: one tension-compression rod 81 i nests the other tension-compression rod 81 i+1 to be able to adapt to different length requirements; the tension-compression rods are one of a channel-section rod and a rectangular-section rod, and the tension-compression rod 81 can also be composed of multiple tension-compression rods, and adjacent tension-compression rods are nested with each other.

[0069] The one tension-compression rod 81 i and the other tension-compression rod 81 i+1 are provided with multiple groups of connection hole groups for adjusting the elongation of the multi-stage tension-compression rods. The multiple tension-compression rods are connected by shear bolts 85, and adjacent two tension-compression rods are connected by at least two shear bolts.

[0070] The fixed wall 821 in the connecting plate 82 of the stabilizing device is fixed to the wall surface of the column 2, and the connecting wall 822 in the connecting plate 82 is fixed to the tension-compression rod 81, increasing the stress at the joint between the column and the tension-compression rod 81 and enabling it to resist greater external forces.

[0071] There are two states for the fixed positions of the connecting wall 822 and the fixed wall 821 in the connecting plate; as Figure 16 shown, in the first state, the connecting wall 822 is installed on the outer side of the fixed wall 821. In this state, the end of the tension-compression rod can be vertically attached and fixed.

[0072] As Figure 17 shown, in the second state, the connecting wall 822 is installed on the outer surface of the fixed wall 821 and they are perpendicular to each other or have a certain inclination angle. In this state, the end of the tension-compression rod can be horizontally attached and fixed.

[0073] An internal fixed shelf further includes a side plate 6 for connecting two said hanging pieces 1 on the same layer from the side of the shelf 5. The side plate 6 includes a first side plate wall 61 for connecting the hanging piece 1 and a second side plate wall 62 for blocking the gap between the placement space 3A of the shelf 5 and the end face of the column.

[0074] It should be noted that: the first side plate wall 61 is provided with a riveting stud 63 connected to the third wall 13 of the hanging piece. When the side plate 6 is installed on the shelf, after being quickly pre-fixed to the third wall 13 of the hanging piece through the riveting stud 63, the riveting stud 63 passes through the through-hole of the third wall of the hanging piece, and is screwed on the third wall 13 of the hanging piece to fasten the riveting stud 63.

[0075] Embodiment 3: The hanging piece includes a first hanging piece wall 11 and a second hanging piece wall 12. The first hanging piece wall 11 and the second hanging piece wall 12 are respectively provided with a first set of hanging piece holes 1A and a second set of hanging piece holes 1B. The column 12 is provided with a first column wall 21 and a second column wall 22. The first column wall 21 and the second column wall 22 are respectively provided with corresponding first column hole groups and second column hole groups; the first set of hanging piece holes 1A is correspondingly connected to the first column hole group, and the second set of hanging piece holes 1B is correspondingly connected to the second column hole group. After the hanging piece 1 is attached and connected to the column 2, at least one pair of hole group axes deviate from the axis of the fastener. The hanging piece further includes a third hanging piece wall (13), and the third hanging piece wall (13) is provided with a through-hole. The side plate is fixed to the third hanging piece wall by screwing the first side plate wall 61 to the third hanging piece wall 13.

[0076] When the first set of hanging piece holes 1A is correspondingly connected to the first column hole group and the second set of hanging piece holes 1B is correspondingly connected to the second column hole group, at least one set of the mating connections is a clearance fit at the beginning of fastening and an interference fit at the end of fastening.

[0077] The hole pitch of the first hole group 1A of the hanging piece is different from that of the first hole group of the column, and the hole pitch of the second hole group 1B of the hanging piece is different from that of the second hole group of the column. The micro degrees of freedom are reduced through the hole pitch and the fitting clearance.

[0078] It should be noted that: the first wall 11 of the hanging piece abuts against the first wall 21 of the column. The first hole group 1A of the hanging piece is connected to the first hole group of the column. The degrees of freedom restricted by the first wall 11 of the hanging piece include X rotation, Z rotation, and Y movement; due to the existence of a small margin in the connection fit, the first wall 11 of the hanging piece has micro degrees of freedom including X movement, Z movement, and Y rotation. The micro degrees of freedom are effectively reduced by setting the hole pitch and the fitting clearance between the first hole group 1A of the hanging piece and the first hole group 2A of the column;

[0079] The second wall 12 of the hanging piece abuts against the second wall 22 of the column. The second hole group 1B of the hanging piece is connected to the second hole group of the column. The degrees of freedom restricted by the second wall 1B of the hanging piece include X movement, Y rotation, and Z rotation;

[0080] Due to the existence of a small margin in the connection fit, the second wall 1B of the hanging piece has micro degrees of freedom including Y movement, Z movement, and X rotation;

[0081] By abutting the first wall 11 of the hanging piece against the second wall 12 of the hanging piece and connecting the first wall 21 of the column and the second wall 22 of the column, the constraints of the two wall surfaces are superimposed and complementary. At the same time, the fitting process of the second wall 12 of the hanging piece causes a slight offset of the center of the first hole group 1A of the hanging piece on the first wall 11 of the hanging piece from the center of the first hole group of the column, further strengthening the restriction of the degrees of freedom.

[0082] Embodiment 4: The cross beam 3 includes a load-bearing beam 31. The two ends of the load-bearing beam are provided with the hanging pieces 1. The load-bearing beam 31 is provided with a first load-bearing wall 311 and a second load-bearing wall 312. The first load-bearing wall 311 and the second load-bearing wall 312 are connected. The first load-bearing wall 311 is connected to the second wall 12 of the hanging piece; the first load-bearing wall 311, the second load-bearing wall and the hanging piece 1 are integrally formed of the same material.

[0083] It should be noted that: the first load-bearing wall 311, the second load-bearing wall of the cross beam 3 and the hanging piece 1 are made of the same continuous material and formed by bending or casting techniques; the cross beam is formed with the first load-bearing wall 311, the second load-bearing wall 312 and the hanging piece 1 on the same plate through a sheet metal bending process, and the first load-bearing wall 311 and the second load-bearing wall 312 form the angle steel section of the load-bearing beam 31;

[0084] The cross beam 3 further includes a load-bearing reinforcement plate 33 which, together with the load-bearing beam 31, forms a closed cross-sectional area of the cross beam. The load-bearing reinforcement plate 33 is customized according to requirements to decorate the appearance of the load-bearing beam 31 and increase the overall structural rigidity of the cross beam 3;

[0085] The cross beam 3 further includes a supplementary piece 34. The supplementary piece 34 connects the first wall 11 of the hanging piece and the load-bearing reinforcement plate 33. The supplementary piece 34 is coplanar with the first wall 11 of the hanging piece, and the supplementary piece has at least a welded part 341 welded to the first load-bearing wall 21. When connecting the load-bearing reinforcement plate 33 to the load-bearing beam 31, the welded part 341 is blocked in the closed space formed by the load-bearing beam 31 and the load-bearing reinforcement plate 33;

[0086] The cross beam hanging piece further includes a third wall 13 of the hanging piece for expanding the side baffle of the shelf. The third wall of the hanging piece is provided with a third hole group 13A for expanding connection;

[0087] It further includes a hanging claw 11A for temporarily hanging the hanging piece on the column 2.

[0088] Embodiment 5: A deployment method of a shelf stability device, the method is as follows:

[0089] Connect the connecting plate 82 according to the fixing requirements of the front view rectangular frame 5A or the top view rectangular frame 5B;

[0090] Match the stable distance L between the two connection positions at the head and tail of the tension and compression rod 81 in the stable device;

[0091] Fine-tune the inclination state of the shelf frame corresponding to the fixing surface of the stable device 8 according to the deviation between the stable distance L and the hole pitch of the two relatively arranged connecting plates 82;

[0092] Connect the stable device 8 and the connecting plate 82;

[0093] Increase the support points for strengthening the stability of the compression rod and connecting to the shelf components within the length range of the stable device 8 according to the stable distance L.

[0094] Embodiment 6: A storage method of a shelf stability device for storing the stable device 8 into the shelf 5,

[0095] Remove the stable device 8 and adjust the tension and compression rod 81 to the contracted state, and store the stable device 8 in the non-material placement area in the contracted state;

[0096] Store the stable device 8 in the non-material placement area;

[0097] When the stabilizing device 8 in the retracted state is stored at the bottom of the shelf, through the connecting holes provided at the head and tail of the stabilizing device 8, it is connected to the side beams 7 of the two side columns of the shelf through flexible connectors, ensuring that the stabilizing device 8 does not cause collision or interference with the shelf components during movement in multiple degrees of freedom.

[0098] The beneficial effects achieved by the present invention are as follows:

[0099] 1. The stabilizing device absorbs external forces in a tensile or compressive manner, effectively solving problems such as deformation and structural damage of the shelf during transportation and movement, and is particularly suitable for in-line shelves with large inertia.

[0100] 2. At the same time, the stabilizing device allows connection at different positions of different shelves or the same shelf through multi-stage length adjustment.

[0101] 3. When the stabilizing device is not needed, it allows for quick disassembly and storage at the bottom of the shelf.

[0102] 4. It can eliminate redundant and cumbersome packaging methods such as wooden frames and display boards, improve operation efficiency, and reduce packaging and transportation costs.

[0103] The above-described embodiments of the present invention do not constitute a limitation to the protection scope of the present invention.
