Description

Technical Field

[0001] This utility model relates to the field of shelving design technology, specifically to a shelving upright docking structure. Background Technology

[0002] In automated warehouse high-bay racking, the uprights are usually quite tall. To facilitate transportation, the uprights are usually divided into multiple upper and lower uprights, which are then assembled on-site. However, the connection structure between the upper and lower uprights still has some defects.

[0003] For example, in the patent application number CN202221256290.2, a connecting device and a shelf, the connecting end of the upper and lower uprights is provided with a joint. After the upper and lower uprights are inserted, they are held together by two U-shaped clamps arranged opposite each other, and the connection is achieved by bolts passing through the two clamps and the upper and lower uprights. Its structure is simple and easy to operate, but the end faces of the connecting ends of the upper and lower uprights need to be cut neatly. The commonly used processing methods for cutting uprights are difficult to guarantee the neatness of the end faces, which affects the straightness of the two uprights after connection. Other machining methods are too expensive.

[0004] In addition, there is a column docking device, for example, with application number CN200320108713.7. The docking plates are welded to the inner sides of the ends of the two columns, and the two docking plates are connected in the middle by bolts. Then, U-shaped reinforcing channel steel is used to connect the docking ends of the two columns by bolts. Although the flatness requirement of the docking surface of the two columns is not high, the columns are usually made of relatively thin pipes. After welding, it is difficult to ensure that the end position of the columns will not be deformed, which makes it difficult to guarantee the straightness of the two columns. In addition, the connection of the two docking plates is relatively difficult. For columns with large side openings, the bolts can be installed through the openings, but for columns without side openings, the bolts will be very difficult to install. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model provides a shelf upright docking structure.

[0006] The technical solution of this utility model is as follows:

[0007] A shelving upright docking structure is used to connect two upper and lower uprights. It includes two docking plates arranged opposite each other and two connecting cylinders on opposite sides. The connecting cylinders are fixed in the middle of the corresponding docking plates, and the two docking plates located on the outside of the connecting cylinders are detachably connected by bolts. The connecting cylinders are designed to allow the uprights to be inserted. The connecting cylinders have connecting holes on the corresponding through holes on the uprights, allowing screws to pass through. Locking nuts are also provided on the screws located on both sides of the connecting cylinders.

[0008] As a further implementation, the two mating plates are provided with bosses and grooves on opposite sides, and are connected by plugging in the bosses and grooves.

[0009] To improve connection accuracy and structural stability, the boss and groove are designed with a trapezoidal dovetail joint structure.

[0010] To enhance adaptability and ease of installation, the cross-sectional shape of the connecting cylinder is the same as that of the column.

[0011] As a further implementation, the column has a rectangular cross-section, and multiple sets of mounting holes for bolts to pass through are provided on both sides of the two mating plates corresponding to the length of the column cross-section. The boss and the groove are set in the direction of the length of the column cross-section.

[0012] Furthermore, the two mating plates are also provided with multiple elongated weight-reducing holes. The distance between the weight-reducing holes and the adjacent mounting holes is not less than the diameter of the mounting holes. The elongated weight-reducing holes on the mating plates reduce weight while maintaining the distance from the mounting holes, avoiding stress concentration and further reducing the risk of deformation.

[0013] To further enhance adaptability and ease of installation, both mating plates and both connecting cylinders are of the same specifications.

[0014] To further improve structural stability, the thickness of the connecting cylinder shall not be less than 1.5 times the thickness of the column, and the thickness of the mating plate shall be 1.5 times the thickness of the column.

[0015] Furthermore, the connecting hole is an elongated hole set along the length of the connecting cylinder. The elongated hole on the connecting cylinder allows the position of the screw to be flexibly adjusted along the length of the column. Even if there is a cutting error on the end face of the column or slight deformation of the mating plate, the deviation can still be compensated by adjusting the locking position of the screw to ensure that the upper and lower columns are aligned in a straight line.

[0016] The beneficial effects of this utility model's shelf upright docking structure are as follows:

[0017] 1. The column is wrapped with a connecting cylinder and fixed with a screw through a long hole. This allows for a certain cutting error on the end face of the column. Compared with the strict requirements for end face flatness of the traditional solution, it reduces the dependence on the cutting accuracy of the column and reduces the need for high-cost machining.

[0018] 2. Abandoning the traditional method of welding columns and connecting plates, a purely mechanical connection method is adopted, in which the connecting plates are bolted and the connecting cylinder is locked with screws, completely avoiding deformation of the column ends caused by welding thermal stress;

[0019] 3. The bolt mounting holes of the two mating plates are located on the outer edge of the mating plates. The bolts can be inserted vertically directly from the outside of the mating plates without the need for openings on the side of the column. Even if the column is a closed structure (such as a rectangular tube without side openings), the operator only needs to insert the bolts and tighten the nuts in the external space, completely eliminating the structural dependence on openings on the side of the column and fundamentally solving the bolt installation problem of closed columns.

[0029] Combination Figure 1 This embodiment provides a docking structure for shelf uprights 1, including two docking plates 2 arranged opposite each other and two connecting cylinders 3 on the opposite side of each other, for connecting the upper and lower uprights 1.

[0030] Combination Figures 2-4 Two columns 1 are vertically opposite each other. The connecting cylinder 3 is fixed in the middle of the corresponding docking plate 2. The two docking plates 2 located outside the connecting cylinder 3 are detachably connected by bolts 4. The connecting cylinder 3 is designed to allow the column 1 to be inserted. The connecting cylinder 3 wraps around the outside of the column 1. The connecting cylinder 3 has a connecting hole 311 on the corresponding through hole on the column 1, which allows the screw to pass through. Locking nuts are also provided on the screws on both sides of the connecting cylinder 3.

[0031] Specifically, the two connecting cylinders 3 are the upper connecting cylinder 31 and the lower connecting cylinder 32, and the two mating plates 2 are the upper mating plate 21 and the lower mating plate 22. The upper connecting cylinder 31 is welded to the middle of the upper side of the upper mating plate 21, and the lower connecting cylinder 32 is welded to the middle of the lower side of the lower mating plate 22. The upper connecting cylinder 31 and the upper mating plate 21 and the lower connecting cylinder 32 and the lower mating plate 22 form a pair of male and female parts.

[0032] Combination Figure 1 The four corners of the two mating plates 2 are rounded to avoid stress concentration. The upper mating plate 21 and the lower mating plate 22 are respectively provided with bosses 211 and grooves 221 on opposite sides, and are connected by plugging in bosses 211 and grooves 221. In order to improve the connection accuracy and structural stability, the bosses 211 and grooves 221 are trapezoidal dovetail plugging structures. The height of the bosses 211 is not less than 1 / 3 of the thickness of the lower mating plate 22. After plugging in, the self-locking characteristic of the dovetail structure can resist horizontal displacement, ensuring that the position of the two uprights 1 after correction is initially stable before the bolts 4 are tightened.

[0033] The two columns 1 are the upper column and the lower column, respectively. When in use, the lower connecting cylinder 32 can be inserted into the lower column first, and the lower connecting cylinder 32 can be connected to the column 1 using a screw and a locking nut. Then, the upper connecting plate 21 and the lower connecting plate 22 can be inserted and connected, and the upper connecting plate 21 and the lower connecting plate 22 can be connected using a bolt 4. Finally, the upper column can be inserted, and the upper connecting cylinder 31 can be connected to the upper column using a screw and a locking nut.

[0034] In addition, the above-mentioned male and female parts can be connected as one unit before assembly. After the columns are transported to the site, the upper and lower columns can be inserted into the corresponding connecting cylinders 3 respectively, and the connecting cylinders 3 can be connected to the columns 1 to achieve rapid on-site installation.

[0035] Among them, the connecting hole 311 is an elongated hole provided along the length direction of the connecting cylinder 3, such as Figure 1 The upper connecting cylinder 31 has an elongated hole. After the upper connecting cylinder 31 is aligned with the through hole of the upper column, the screw is inserted and fixed by locking nuts on both sides. The elongated hole design allows the position of the screw to be flexibly adjusted along the length of the upper column. Even if there is a cutting error on the end face of the upper column or slight deformation of the upper mating plate 21, the deviation can still be compensated by adjusting the locking position of the screw, thereby ensuring that the upper and lower columns are aligned in a straight line.

[0036] Combination Figures 4-6The cross-sectional shape of the connecting cylinder 3 is the same as that of the column 1. For the rectangular cross-section column 1, the upper connecting plate 21 and the lower connecting plate 22 are provided with multiple sets of mounting holes 212 for bolts 4 to pass through on both sides corresponding to the cross-sectional length of the column 1. The boss 211 and the groove 221 are set from one side of the connecting plate 2 in the direction corresponding to the length of the cross-section of the column 1, and the length is less than the length of the cross-section of the column 1, so as to play a positioning role and realize rapid positioning and fitting.

[0037] Not only can the elongated hole be used to adjust the straight alignment of the upper and lower columns 1, but the cross-sectional shape of the connecting cylinder 3 is the same as the shape of the column 1. That is, the inner cavity of the connecting cylinder 3 is completely matched with the outer contour of the column 1, thus forming a full circumferential contact. When the column 1 is inserted, its four sides are precisely limited by the inner wall of the connecting cylinder 3, eliminating the possibility of X / Y direction offset in the horizontal plane and forcibly guiding the upper and lower columns 1 to be straight aligned.

[0038] To enhance adaptability and ease of installation, the upper connecting plate 21 and the lower connecting plate 22 are of the same specifications, and the two connecting cylinders 3 are of the same specifications. This standardized design improves the efficiency of modular installation.

[0039] To improve structural stability, the thickness of the connecting cylinder 3 is not less than 1.5 times the thickness of the column 1, and the thickness of the upper connecting plate 21 and the lower connecting plate 22 is 1.5 times the thickness of the column 1. The height of the connecting cylinder 3 is not less than 1 / 8 to 1 / 6 of the height of the column 1, so as to balance the connection strength and material cost.

[0040] Combination Figure 1 and Figure 4 The upper connecting plate 21 and the lower connecting plate 22 are also provided with a number of elongated weight-reducing holes 213. The distance between the weight-reducing hole 213 and the adjacent mounting hole 212 is not less than the diameter of the mounting hole 212. The elongated weight-reducing holes 213 on the upper connecting plate 21 and the lower connecting plate 22 reduce the weight while maintaining the distance from the mounting hole 212 to avoid stress concentration and further reduce the risk of deformation. The weight-reducing holes 213 on the upper connecting plate 21 and the lower connecting plate 22 are set along the length direction of the cross section of the column 1.
