Abstract
Description
Technical Field
[0001] The utility model belongs to the field of material racks, in particular to a floor beam material rack. Background Art
[0002] Automotive floor beams, or longitudinal crossbeams within the vehicle chassis, are a crucial component of the vehicle's structure. As a key component in the automotive manufacturing and repair industries, the safety and efficiency of their storage and transportation are crucial.
[0003] Traditional floor beam racks suffer from complex structures, limited load-bearing capacity, and low space utilization, making them difficult to meet the demands of modern production. Alternatively, multiple racks are installed within the racks. Before the floor beams can be stored within the racks, a rack must be pulled out, the floor beams placed on top, and finally the rack pushed back into the racks. While this method provides adequate storage for the floor beams, the entire storage process is cumbersome, time-consuming, and labor-intensive, and it also hinders later retrieval. Utility Model Content
[0004] In view of the above problems, the purpose of the present invention is to provide a floor beam rack, which aims to solve the problem that the process of storing floor beams in the existing floor beam rack is troublesome, time-consuming and labor-intensive, and is not conducive to later material retrieval.
[0005] The utility model adopts the following technical solutions:
[0006] The floor beam rack includes a bottom frame, and a plurality of upper frame positioning mechanisms are provided in the bottom frame. The upper frame positioning mechanisms include a pair of left and right upper frame positioning assemblies, wherein the left upper frame positioning assembly is arranged horizontally and the right upper frame positioning assembly is arranged longitudinally. The upper frame positioning assembly includes a column, and a plurality of see-saws are provided in the column along the height rotation. The tail of each see-saw is provided with a counterweight wheel for rotation through an axle rod, and a linkage plate is provided between the two axles at the same end and adjacent to each other up and down. The lower part of the linkage plate is rotatably installed on the lower axle rod, and a short slot is provided above the linkage plate and the upper axle rod is located in the short slot. A limiting pressure block is provided in the column and at the other end and above of each axle rod, and a support block is provided on the inner wall of the column below the lowest axle rod.
[0007] Furthermore, the inner wall of the column is provided with a limit block directly below the lower part of the shaft rods except the lowermost shaft rod.
[0008] Furthermore, the front end of the seesaw is bent upward and forward.
[0009] Furthermore, the two adjacent upper frame positioning mechanisms are staggered.
[0010] Furthermore, a guide column is provided on the bottom frame toward each upper frame positioning assembly.
[0011] Furthermore, an L-shaped support frame is provided on the top surface of the bottom frame, shovel feet are provided between the four corners of the bottom surface, and a pair of corner frames are provided inside the support frame.
[0012] Furthermore, a pair of inner and outer transverse guide plates are provided at the front end of the left column, and a longitudinal guide plate is provided at the front end of the right column.
[0013] The beneficial effect of the present invention is that after the first floor beam is placed, the two seesaws on the upper layer will rotate downward a short distance at the same time, and their front ends will be exposed a short distance from the pillars to form a discharge position. Then the next floor beam can be lowered to the new discharge position as required, and this cycle will continue until floor beams are stacked on each layer of the seesaw in the current upper frame positioning mechanism, and then the next upper frame positioning mechanism will be loaded. All floor beams do not touch each other, which can avoid damage to them during the loading and storage process, and the entire loading process is relatively simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.
[0020] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.
[0021] For the sake of convenience, only the parts related to the embodiments of the present invention are shown.
[0022] Combine Figure 1-5As shown, the floor beam rack includes a bottom frame 1, and a plurality of upper frame positioning mechanisms are provided in the bottom frame 1. The upper frame positioning mechanisms include a pair of left and right upper frame positioning assemblies, with the left upper frame positioning assembly being marked 21 and the right upper frame positioning assembly being marked 22. The left upper frame positioning assembly 21 is arranged horizontally, and the right upper frame positioning assembly 22 is arranged vertically. The upper frame positioning assembly includes a column 3, in which a plurality of see-saws 4 are provided for rotation along the height. The tail of each see-saw 4 is provided with a counterweight wheel 6 for rotation through a shaft 5. A linkage plate 7 is provided between two shafts 5 adjacent to each other at the same end. The lower part of the linkage plate 7 is rotatably mounted on the lower shaft. A short slot 8 is provided above the linkage plate 7, and the upper shaft is located in the short slot 8. A limit pressure block 9 is provided in the column 3 and located at the other end of each shaft 5 and directly above it. A support block 16 is provided on the inner wall of the column 3 below the lowest shaft.
[0023] Automotive floor beams, or longitudinal beams within the vehicle chassis, are a crucial component of the vehicle's structure. Once the floor beams are complete, they can be stacked in order within the racks, saving significant storage space. Furthermore, the individual floor beams avoid contact, preventing scratches during transportation.
[0024] The floor beam rack includes a bottom frame, such as Figure 1-2 In this embodiment, the bottom frame is provided with four upper frame positioning mechanisms, each of which can accommodate multiple floor beams. Adjacent upper frame positioning mechanisms are staggered to avoid interference when removing and placing floor beams.
[0025] The upper frame positioning mechanism includes a pair of left and right upper frame positioning assemblies, with the left upper frame positioning assembly arranged horizontally and the right upper frame positioning assembly arranged vertically. When the floor beams are placed one by one and in an orderly manner as required within the upper frame positioning mechanism, the left upper frame positioning assembly supports the leftmost end of the floor beam, while the right upper frame positioning assembly supports the right end of the floor beam.
[0026] Before the floor beams are placed into the upper frame positioning mechanism for storage, a support block is provided below the lowest shaft rod, which supports the lowest shaft rod. Therefore, the two lowest seesaws are supported by the support block and are slightly above the column, forming a discharge position. When the first floor beam is placed into the upper frame positioning mechanism, the two ends of the first floor beam fall on the corresponding discharge positions. Under the weight of the floor beam, the two lowest seesaws rotate downward, and the counterweight wheels at their tails rotate upward until the shaft rod on the counterweight wheel contacts the corresponding limit pressure block at the bottom. At this point, the two lowest seesaws are perpendicular to the column, completing the storage of the first floor beam.
[0027] As the counterweight wheel rotates upward, it pushes the corresponding linkage plate upward a certain distance. This linkage plate then pushes the previous counterweight wheel upward a short distance. Simultaneously, the two seesaws on the upper level rotate downward a short distance, their front ends slightly exposed above the columns to form the unloading position. The next floor beam can then be lowered to the new unloading position as required. This cycle continues until each level of the seesaw in the current upper frame positioning mechanism has a floor beam stacked on it. Then, loading can proceed to the next upper frame positioning mechanism. Once the rack is full, all floor beams are free from contact, preventing damage during loading and storage, and simplifying the loading process.
[0028] Of course, a retrieving mechanism, such as a robotic arm, can be used during material removal. When using a robotic arm, the arm first removes the topmost floor beam within the upper frame's positioning mechanism. The two seesaws in the topmost layer then rotate upward under the weight of the counterweight wheel and return to the uprights, creating a clear path for the next floor beam. This eliminates the need for human intervention and allows for rapid material removal.
[0029] In addition, if Figure 5 Limit blocks 17 are located on the inner wall of the column 3, directly below all shafts except the lowest one. During the material removal process, after removing the top floor beam, the two weighted wheels on the top layer rotate downward until the two seesaws on the top layer are properly reset inside the column. At this point, the limit blocks support and retain the shafts of the counterweight wheels. The limit blocks ensure that the seesaws can be accurately reset.
[0030] As a priority structure, such as Figure 1 、 Figure 3 The front end of the left column 3 is provided with a pair of inner and outer transverse guide plates, wherein the inner transverse guide plate is marked as 101 and the outer transverse guide plate is marked as 102. The front end of the right column 3 is provided with a longitudinal guide plate 11. The bottom frame 1 is provided with a guide column 12 facing each upper frame positioning assembly.
[0031] In this structure, the width of the inner transverse guide plate 101 is slightly wider than that of the outer transverse guide plate 102. When placing the floor beams into the upper frame positioning mechanism, all guide plates and corresponding guide posts serve as guides, ensuring that the floor beams land accurately on the seesaws at each level. When the seesaws on the same level support both ends of the floor beams, the inner transverse guide plates and guide posts are positioned on either side of the floor beams. At this point, they hold the floor beams in place, allowing them to be stably stacked within the rack.
[0032] In this structure, if Figure 3-4 The front end of the seesaw 4 is bent upward and forward. This design of the seesaw can block and limit the floor beams. It further allows the floor beams to be stably stacked on the two seesaws on the same floor.
[0033] In addition, if Figure 1-2 The top surface of the base frame 1 is provided with an L-shaped support frame 13, with shovel feet 14 positioned between the four corners of the bottom surface. A pair of corner brackets 15 are positioned within the support frame 13. In practice, if the current floor beam rack is already full of floor beams, a forklift can be used. Specifically, the forklift's forklift arm can be inserted into the opening of the shovel feet on the same side. The forklift can then lift the current floor beam rack and place it on top of the previous floor beam rack for stacking. At this point, the four shovel feet at the bottom of the current floor beam rack are positioned on top of the four support frames in the previous floor beam rack. The corner brackets also position the shovel feet on the shovel foot support frames, making the stacking of the upper and lower racks more stable and enabling the racks to be stacked, saving transportation costs.
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
