[0050] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0051] As mentioned above, the longitudinal beam of the semi-trailer is an I-beam composed of two wing plates and a web plate. Generally, in order to realize the modular production and flexible production of the semi-trailer, the longitudinal beam of the semi-trailer is divided into two sections, namely the front longitudinal beam and the rear longitudinal beam, the length of the front longitudinal beam is 5 to 6 meters, and the length of the rear longitudinal beam is 10 to 12 meters. The length of the web plate and the wing plate constituting the front longitudinal beam is also approximately 5 to 6 meters, and the length of the web plate and the wing plate constituting the rear longitudinal beam is approximately 10 to 12 meters. The semi-trailer longitudinal beam parts storage device of the present invention can be suitable for the storage of the front longitudinal beam parts, the storage of the rear longitudinal beam parts, and the storage of the entire longitudinal beam parts. According to the length of the stored longitudinal beam, the size of the semi-trailer longitudinal beam parts storage device can be adjusted.

[0052] like Figures 1 to 4 As shown, Figure 1 It is a three-dimensional structural schematic diagram of the semi-trailer longitudinal beam parts storage device of the present invention, Figure 2 It is a top view of the storage device for longitudinal beam parts of a semi-trailer of the present invention, Figure 3 It is a side view of the storage device for the longitudinal beam parts of the semi-trailer of the present invention. The storage device 100 for the longitudinal beam parts of the semi-trailer of the present invention comprises a stand 10, a lifting and supporting mechanism 20 arranged on the stand 10, and a telescopic propulsion mechanism 30 arranged on the lifting and supporting mechanism 20. The stand 10 is provided with at least one layer of partition 11, and the partition 11 is used to place a material tray 40 containing the longitudinal beam parts of the semi-trailer. The lifting and supporting mechanism 20 is used to lift the material tray 40 to the height of the corresponding partition 20, and the telescopic propulsion mechanism 30 pushes the material tray 40 to the corresponding partition 11, so that the various parts of the longitudinal beam are stored in layers on the stand 10 through the material tray, reducing the space occupied by the parts.

[0053] Specifically, the stand 10 includes two pairs of columns 12 arranged in the longitudinal direction and parallel to each other, a top longitudinal beam 13 connecting the top of the same pair of columns 12, and a top transverse beam 14 connecting the top of different pairs of columns 12. The two pairs of columns 12 form a three-dimensional storage space. Three layers of partitions 11 are connected between the two pairs of columns 12 and arranged in layers along the height of the columns 12. Each layer of partition 11 includes a transverse slide rail arranged between the two pairs of columns 12 for supporting the material tray 40. A slide rail 15 extending in the axial direction is arranged on the side of the column 12, and the lifting and lifting mechanism 20 cooperates with the slide rail 15 to move up and down along the height direction of the column 12.

[0054] It should be noted here that Figure 1 The direction pointed by the X axis is defined as the lateral direction, the direction pointed by the Y axis is defined as the longitudinal direction, and the direction pointed by the Z axis is defined as the axial direction (or height direction).

[0055] Combination Figure 4 As shown, Figure 4 It is a structural diagram of a lifting and supporting mechanism and a telescopic propulsion mechanism. The lifting and supporting mechanism 20 includes two lifting and supporting assemblies 21 respectively installed on two columns in the longitudinal direction. Each lifting and supporting assembly 21 includes a bracket 211 for lifting the material tray 40 and a lifting power device (not shown) for driving the bracket 211 to lift and lower. One end 212 of the bracket 211 is provided with a slide groove that cooperates with the slide rail 15 on the column 12. The bracket 211 includes a lifting beam 2111 arranged in the transverse direction, rollers 2112 arranged at intervals on the lifting beam 2111, a baffle 2113 arranged at the other end of the bracket 211, and a reinforcing beam 2114 arranged along the transverse direction. Combined with Figure 3 As shown, triangular plates 2114a are provided on both sides of the reinforcing beam 2114. When the bracket 211 lifts the material tray 40, the roller 2112 is used to assist the movement of the material tray 40, and the baffle 2113 blocks the material tray 40 at the end to prevent the material tray 40 from sliding out of the end of the bracket 211. The reinforcing beam 2114 is used to enhance the supporting capacity of the bracket 211.

[0056] A telescopic propulsion mechanism 30 is correspondingly provided on each lifting and supporting assembly 21. The telescopic propulsion mechanism 30 is installed on the triangular plate 2114a of the reinforcing beam 2114 of the lifting and supporting mechanism 20 through a mounting plate. The telescopic propulsion mechanism 30 protrudes from the lifting and supporting mechanism 20 and can move with the movement of the lifting and supporting mechanism 20. The telescopic propulsion mechanism 30 includes a sliding rail 31 installed on the mounting plate, a sliding beam 32 that can move along the sliding rail 31, a sliding drive motor 33 provided on the sliding beam 32, and a telescopic plate 34 that is provided on the top surface of the sliding beam 32 and is driven to extend and retract by the sliding drive motor 33. A slider (not shown) is provided at the bottom of the sliding beam 32 that cooperates with the sliding rail 31. The slider is connected to the sliding drive motor 33 through a gear and is driven by the sliding drive motor 33 to drive the sliding beam 32 to move toward or away from the partition 11. Figure 5 As shown, Figure 5 It is a structural schematic diagram of the telescopic plate of the telescopic propulsion mechanism in the extended state. A gear is arranged on the top of the sliding beam 32, and the gear is respectively connected to the telescopic plate 34 and the sliding drive motor 33. Driven by the sliding drive motor 33, the telescopic plate 34 can move relative to the sliding beam 32 to telescope in the direction of approaching or moving away from the partition 11.

[0057] The material tray 40 is placed on the top surface of the telescopic plate 34. When the lifting and lifting mechanism 20 lifts the material tray to the position of the interlayer 11, the sliding drive motor 33 drives the sliding beam 32 to move, and the sliding beam 32 drives the material tray 40 to move. When the sliding beam 32 moves to the position closest to the interlayer 11, the sliding drive motor 33 drives the telescopic plate 34 to extend and push the material tray 40 onto the interlayer 11. When the material tray 40 is put into storage, the sliding drive motor 33 drives the telescopic plate 34 to retract, and the sliding beam 32 also returns to its position under the action of the sliding drive motor 33. When the lifting and lifting mechanism 20 completes the lifting and storage of one layer of material trays, the lifting and lifting mechanism 20 descends and lifts the next material tray 40 into storage until three material trays 40 are put into storage.

[0058] Correspondingly, when all the parts on the tray 40 are taken out, the lifting and lifting mechanism 20 is lifted to the height where the empty tray is located, and the sliding drive motor 33 drives the sliding beam 32 to move in the direction close to the partition 11. When the sliding beam 32 moves to the position closest to the partition 11, the sliding drive motor 33 drives the telescopic plate 34 to extend, and the empty tray falls on the telescopic plate 34. The sliding drive motor 33 drives the telescopic plate 34 to contract and lift the tray 40 out of the partition 11. When the telescopic plate 34 retracts to its original position, the sliding drive motor 33 drives the sliding beam 32 to move in the direction away from the partition 11. When the sliding beam 32 returns to its initial position, the bracket 211 descends to the loading area to wait for loading.

[0059] Combination Figure 6 As shown, Figure 6 This is a simplified structural diagram of a three-layer material tray placed on a stand. In order to clearly show the placement and structure of the material tray, other functional structures on the stand are omitted. Figure 6 As shown, the stand 10 is provided with three layers of partitions 11, and a material tray 40 is placed on each partition 11. The parts constituting the longitudinal beam include webs and wing plates, and two of the three layers of partitions 11 are used to place web material trays 41 for stacking webs, and the other two layers of partitions are used to place wing material trays 42 for stacking wing plates.

[0060] like Figure 7 As shown, Figure 7 The figure is a schematic diagram of the structure of a web tray for stacking webs. The web tray 41 includes a bottom plate 411 and a support frame 412 arranged in a row on the bottom plate 411 along the length direction of the bottom plate 411. Rollers 413 are also arranged on both sides of the bottom plate 411. The rollers 413 can cooperate with the transverse slide rails of the interlayer 11 to help the movement of the tray. The web is placed on the support frame 412 so that the web is in an upright state. The support frame 412 includes a plurality of triangular support plates 4121 arranged at intervals along the length direction of the bottom plate 411 and a connecting rod 4122 connecting two adjacent triangular support plates 4121.

[0061] like Figure 8 As shown, Figure 8The structure diagram of the flap tray for stacking flaps is shown in FIG. The flap tray 42 includes a chassis 421 and a flap slot group 422 arranged in a row on the chassis 421 along the width of the chassis 421. Two adjacent rows of flap slot groups 422 are spaced at a predetermined distance to accommodate flaps 43 of different lengths. Rollers 423 are also arranged on both sides of the chassis 421. The rollers 423 cooperate with the transverse slide rails of the interlayer 11 to help the movement of the tray. The flap slot group 422 includes a plurality of slots 4221 and protrusions 4222 alternately arranged. The flaps 43 are placed along the length direction of the chassis 421 and are clamped in the slots 4221 of at least two groups of flap slot groups 422.

[0062] The amount of parts stored in the web tray 41 and the wing tray 42 is determined according to actual production. Preferably, the amount of parts stacked in the web tray 41 and the wing tray 42 is the amount of parts required for daily production of the production line.

[0063] Please refer to Figures 1 to 3 The semi-trailer longitudinal beam parts storage device 100 further includes a grabbing mechanism 50 disposed on the top of the stand 10 and a conveying roller 60 disposed on the side of the stand 10 and extending longitudinally.

The lifting grabbing mechanism 50 also includes a support block 501 installed on two columns 12 in the longitudinal direction and a mounting beam 502 installed on the two support blocks 501 at both ends. The lifting drive mechanism 51 is installed on the mounting beam 502. The telescopic propulsion mechanism 30 lifts the material tray 40 from the partition 11 to a position suitable for the grabbing mechanism 50 to grab, and the lifting drive mechanism 51 drives the grabbing part 52 to descend, so that the grabbing part grabs the parts from the material tray 40 and places the parts on the conveyor roller 60, and the conveyor roller 60 conveys the parts to the next process.

[0064] The grabbing mechanism 50 further includes a first connecting rod 531 connected to the lifting driving mechanism 51, a gear connected to the first connecting rod 531 and driven to rotate by the first connecting rod 531 (not shown, the gear is encapsulated in a mounting box 534, and the mounting box 534 is fixed on the mounting beam 502), a rack 532 meshed with the gear, a suspension beam 533 suspended at the end of the rack 532, and a plurality of cantilever mounting parts 534 installed at intervals on the suspension beam 533 for mounting the grabbing part 52. The grabbing part 52 is mounted on the suspension beam 533 through the suspension mounting parts 534. When the lifting driving mechanism 51 drives the first connecting rod 531 to rotate, the first connecting rod 531 drives the gear to rotate, and when the gear is meshed with the rack 532, the suspension beam 533 is lifted, and when the gear is separated from the rack 532, the suspension beam 533 is lowered, thereby realizing the lifting and lowering of the grabbing part 52.

[0065] There are multiple gripping parts 52. Fig.11 As shown, Fig.11 Schematic diagram of the structure of the grabbing part in one embodiment. Each grabbing part 52 includes a cantilever 521 and a grabbing execution part 522 installed on the cantilever 521.

The first pressing actuating component 5223 and the second pressing actuating component 5224 are respectively provided with opposite clamping blocks 5223a and 5224a at their bottom ends. The first pressing actuating component 5223 is connected to the cantilever 521.

[0067] The top of the first pressing actuating member 5223 is provided with a semicircular groove 5226 for matching with the pressing pin 5222.

The pressing rotating shaft 522 is installed at a position close to the cantilever 521. When the cylinder 5221 is extended, the pressing pin 5222 moves downward to act on the first pressing actuating member 5223, so that the first pressing actuating member 5223 rotates obliquely downward relative to the pressing rotating shaft 5225, so that the first pressing actuating member 5223 moves toward the direction of the second pressing actuating member 5224, and the distance between the clamping block 5223a and the clamping block 5224a is narrowed to clamp the parts of the longitudinal beam of the semitrailer. When the cylinder 5221 contracts, the push pin 5222 moves upward, releasing the effect on the first clamping actuating component 5223. The first clamping actuating component 5223 rotates obliquely upward around the clamping shaft 5225, and the distance between the clamping block 5223a and the clamping block 5224a widens, loosening the parts of the semi-trailer longitudinal beam.

After placement, the material tray 40 is lifted as a whole onto the lifting and supporting mechanism 20 by a forklift or a crane; the lifting and supporting mechanism 20 lifts the material tray 40 to the specified height layer (3 layers in total), and the lifting movement stops; the material tray 40 is driven by the telescopic propulsion mechanism 30 and enters the three-dimensional material warehouse formed by the frame 10; after the material tray 40 is put into storage, the telescopic propulsion mechanism 30 is retracted, and the lifting and supporting mechanism 20 is lowered to the lowest position, completing the entire material tray storage process.

[0079] Parts outbound process:

[0080] The lifting mechanism 20 is lifted to the height of the compartment corresponding to the parts to be taken out of the warehouse; under the action of the telescopic propulsion mechanism 30, the material tray 40 is pushed to the range that the grabbing mechanism 50 can grab; the grabbing mechanism 50 descends to grab or adsorb the parts on the material tray 40. The grabbing mechanism 50 is lifted to take the parts out of the material tray 40, and the grabbing mechanism 50 is lowered to place the parts on the conveyor roller 60, and the conveyor roller 60 conveys the parts to the next production process.

[0081] like Fig.16 As shown, it is a schematic diagram of the longitudinal beam structure of a semi-trailer. Each longitudinal beam 400 is composed of two wing plates 43 and one web plate 44. By repeating the steps of the above-mentioned parts outsourcing process, the outsourcing process of three parts of a longitudinal beam can be completed.

[0082] The storage device for parts of a semitrailer longitudinal beam of the present invention can reduce the floor space occupied by parts by arranging a plurality of interlayer storage trays and utilizing three-dimensional space to store the trays.
