Description

Technical Field

[0001] This application relates to the field of support frames, and more specifically to an adjustable cargo support frame. Background Technology

[0002] Using transport vehicles to transport goods is a widely used form of freight transportation in current social production. By modifying the vehicle compartments, it is possible to transport specific goods over long distances more conveniently and efficiently. However, in the transportation of sheet metal goods, due to the shape limitations and stacking methods of the sheets, the traditional carriage transportation method is very inconvenient for stacking and securing the sheets. The loading and unloading time is long, and the sheets need to be repeatedly secured during loading, resulting in low loading and unloading efficiency for sheet metal goods.

[0003] Therefore, this application designs an adjustable cargo support frame that can be adjusted according to the thickness of the sheet material to facilitate loading of sheet material goods onto a vehicle. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable cargo support frame, which aims to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable cargo support frame, including a carriage, an inclined leaning frame, a foot support frame, and a spacing switching mechanism that allows the spacing of the foot support frame to change according to the thickness of the plate; the inclined leaning frame is bolted to the inner side wall of the carriage, the foot support frame is slidably connected to the bottom wall of the carriage, one end of the spacing switching mechanism is bolted to the inside of the bottom wall of the carriage, and the other end of the spacing switching mechanism is rotatably connected to the foot support frame;

[0006] The spacing switching mechanism is equipped with a diamond-shaped connecting rod. The hinge of the diamond-shaped connecting rod is rotatably connected to the foot support frame. The side of the plate cargo rests against the inclined support frame, and the lower end contacts the foot support frame. The spacing switching mechanism drives the diamond-shaped connecting rod to rotate and move. The displacement of the diamond-shaped connecting rod drives the foot support frame to change the spacing.

[0007] The diamond-shaped connecting rod is displaced by the set interval switching mechanism, which in turn causes the foot support frame to retract or expand, changing the spacing of the foot support frame to accommodate the mutual leaning of plates of different thicknesses. By limiting the tilt of the foot support frame and the plate, the plates are placed in this way during the loading process and finally fixed in place. This effectively improves the loading efficiency of plate goods and reduces the labor intensity of operators.

[0008] Furthermore, the lower part of the carriage is equipped with a floor plate, the surface of which has two sets of sliding grooves, and the interior of the floor plate has a hollow section. The foot support frame includes an array of sliding blocks and an array of inclined plates; the upper end of the sliding block is inserted into the lower end of the inclined plate, the two sides of the sliding block are slidably connected to the floor plate through the sliding grooves, and the lower end of the sliding block is rotatably connected to the rhomboid connecting rod hinge. Two sets of foot support frames are provided, and the two sets of foot support frames are respectively positioned at both ends of the floor plate surface.

[0009] Furthermore, the spacing switching mechanism includes a drive assembly, two sets of sliding racks, and two sets of connecting rods; the lower end of the drive assembly is bolted to the inside of the base plate, the sliding racks are slidably connected to the inner wall of the base plate, one end of each of the two sets of connecting rods is rotatably connected to the ends of two sets of rhomboid connecting rods, and the other end of the connecting rods is inserted into the side of the sliding racks. The drive assembly includes a gear and a rotating rod; the lower end of the gear is inserted into the rotating rod, and a motor is inserted into the end of the rotating rod away from the gear. The motor is bolted to the base plate, and the sliding racks are positioned on both sides of the gears, meshing with the gears.

[0010] Furthermore, a sliding rod is provided at the lower end of the hinge of the rhomboid connecting rod, and the rhomboid connecting rod is slidably connected to the inner wall of the base plate through the sliding rod. A positioning rod is rotatably provided at the lower end of the hinge near both ends of the base plate of the rhomboid connecting rod, and the positioning rod is inserted into the base plate so that the side of the rhomboid connecting rod near the end of the base plate does not undergo horizontal displacement. The lower end of the inclined plate is provided with evenly distributed balls to reduce the friction force between the inclined plate and the surface of the base plate.

[0011] Compared with existing technologies, it has the following beneficial effects:

[0012] This utility model provides an adjustable cargo support frame. The diamond-shaped connecting rod is driven to move by a set interval switching mechanism, which in turn causes the foot support frame to retract or expand. The spacing of the foot support frame is changed to accommodate the mutual leaning of plates of different thicknesses. By limiting the tilt of the plates through the foot support frame and the plates, the plates are placed in this way during the loading process and finally fixed in place. This effectively improves the loading efficiency of plate cargo and reduces the labor intensity of operators. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 6 As shown, this utility model provides the following technical solution: an adjustable cargo support frame, including a carriage 1, an inclined leaning frame 2, a foot support frame 3, and a spacing switching mechanism 4 that allows the spacing of the foot support frame 3 to change according to the thickness of the plate; the inclined leaning frame 2 is bolted to the inner side wall of the carriage 1, the foot support frame 3 is slidably connected to the bottom wall of the carriage 1, one end of the spacing switching mechanism 4 is bolted to the inside of the bottom wall of the carriage 1, and the other end of the spacing switching mechanism 4 is rotatably connected to the foot support frame 3;

[0022] The spacing switching mechanism 4 is equipped with a rhomboid connecting rod 5. The hinge of the rhomboid connecting rod 5 is rotatably connected to the foot support frame 3. The side of the plate cargo rests against the inclined support frame 2, and the lower end contacts the foot support frame 3. The spacing switching mechanism 4 drives the rhomboid connecting rod 5 to rotate and move; the displacement of the rhomboid connecting rod 5 drives the foot support frame 3 to change the spacing.

[0023] See Figure 1 and Figure 2 The lower part of the carriage 1 is provided with a floor plate 11, and two sets of sliding grooves 12 are opened on the surface of the floor plate 11. A hollow part 13 is opened inside the floor plate 11. The hollow part 13 mainly provides space for the spacing switching mechanism 4. The spacing switching mechanism is connected to the inner wall of the floor plate 11 through the hollow part 13.

[0024] See Figure 2 as well as Figure 3 The foot support frame 3 includes an array of sliding blocks 31 and an array of inclined plates 32; the upper end of the sliding block 31 is inserted into the lower end of the inclined plate 32, the two sides of the sliding block 31 are slidably connected to the base plate 11 through the sliding groove 12, and the lower end of the sliding block 31 is rotatably connected to the rhomboid connecting rod 5 at the hinge.

[0025] The tilting slope of the tilting plate 32 is the same as that of the tilting support frame 2. The plate is placed on the first tilting plate 32 so that the side of the plate is in contact with the tilting support frame 2. Then, the subsequent plates are placed on the tilting plate 32 in turn so that the side of the rear plate is in contact with the front plate. The plates lean forward as a whole under the weight of gravity, concentrating the weight on the tilting support plate, while the plates do not bear excessive weight from each other.

[0026] When different batches of plates are loaded onto the vehicle, if the thickness of the plate is greater than the length of the inclined side of the inclined plate 32, the diamond connecting rod 5 is displaced by the interval switching mechanism, which changes the spacing between the inclined plates 32. The spacing is changed so that the vertical projection of the last end of the plate is located at the lowest point of the front end of the inclined plate 32, thus completing the spacing adjustment. The side of the plate can then completely fit against the previous plate.

[0027] In another embodiment, two sets of foot support brackets 3 are provided, and the two sets of foot support brackets 3 are respectively positioned at both ends of the surface of the base plate 11.

[0028] Among them, the two sets of foot support frames 3 are positioned at the upper left and lower right of the base plate 11, so that the carriage 1 can be fully loaded and any piece of plate is limited. When switching between intervals, the two sets of foot support frames 3 on both sides need to be tilted and the plate 32 parallel to each other when unfolded so that the plate can be loaded.

[0029] See Figures 3 to 6 The spacing switching mechanism 4 includes a drive assembly 41, two sets of sliding racks 42 and two sets of connecting rods 43; the lower end of the drive assembly 41 is bolted to the inside of the base plate 11, the sliding racks 42 are slidably connected to the inner wall of the base plate 11, one end of the two sets of connecting rods 43 is rotatably connected to the ends of the two sets of rhomboid connecting rods 5 respectively, and the other end of the connecting rods 43 is inserted into the side of the sliding racks 42.

[0030] When the spacing of the foot support frame 3 needs to be switched, the two sets of sliding racks 42 are driven to move in opposite directions by the drive assembly 41. Through the transmission of the connecting rod 43, the end of the rhomboid connecting rod 5 is displaced, thereby causing the rhomboid connecting rod 5 to expand or contract. The rhomboid connecting rod 5 then drives the sliding block 31 to move along the slide groove 12, causing the inclined plates 32 to move and the spacing between the inclined plates 32 to change in the same way.

[0031] See Figure 4 as well as Figure 5The drive assembly 41 includes a gear 411 and a rotating rod 412. The lower end of the gear 411 is inserted into the rotating rod 412, and a motor is inserted into the end of the rotating rod 412 away from the gear 411. The motor is bolted to the base plate 11. A sliding rack 42 is positioned on both sides of the gear 411 and meshes with the gear 411. The motor drives the rotating rod 412 to rotate, and the rotation of the rotating rod 412 drives the gear 411 to rotate. Since the sliding rack 42 is located on both sides of the gear 411, and the sliding connection between the sliding rack 42 and the base plate 11 has a limit, the two sets of sliding racks 42 are driven by the gear 411 to undergo horizontal displacement in opposite directions, which drives the connecting rod 43 to drive the diamond connecting rod 5 to move, thereby realizing the expansion or contraction of the foot support frame 3.

[0032] See Figures 3 to 6 A sliding rod 51 is rotatably provided at the lower end of the hinge of the rhomboid connecting rod 5. The rhomboid connecting rod 5 is slidably connected to the inner wall of the base plate 11 through the sliding rod 51. A positioning rod 52 is rotatably provided at the lower end of the hinge near both ends of the base plate 11. The positioning rod 52 is inserted into the base plate 11 so that the side of the rhomboid connecting rod 5 near the end of the base plate 11 does not undergo horizontal displacement.

[0033] The positioning rod 52 limits the hinge point of the rhomboid connecting rod 5 away from the gear 411 so that it will not be horizontally displaced, thus preventing the inclined locking block at the end from being displaced. While the connecting rod 43 drives the rhomboid connecting rod 5 to move, the sliding rod 51 slides along the track on the inner wall of the base plate 11, while providing support for the inclined locking plate 32 at the top.

[0034] It should be noted that the lower end of the tilting plate 32 is provided with evenly distributed ball bearings to reduce the friction between the tilting plate 32 and the surface of the base plate 11; the motor has a locking function, and the motor can be locked after the spacing is switched, so that the diamond connecting rod 5 is locked, so that the tilting block will not be displaced by gravity.

[0035] Working principle: In use, the sheet material is placed on the first inclined pallet 32, so that the side of the sheet material is in contact with the inclined support frame 2. Then, the subsequent sheets material is placed on the inclined pallet 32 ​​in turn, so that the side of the rear sheet material is in contact with the front sheet material. After all the materials are placed, they are fixed at the last sheet material to complete the loading of the sheet material goods. When different batches of sheets material of different thicknesses are loaded, if the sheet material thickness is greater than the length of the inclined side of the inclined pallet 32, the drive assembly 41 drives the two sets of sliding racks 42 to move in opposite directions. Through the transmission of the connecting rod 43, the end of the rhomboid connecting rod 5 is displaced, which causes the rhomboid connecting rod 5 to expand or contract. The rhomboid connecting rod 5 then drives the sliding block 31 to move along the slide groove 12, causing the inclined pallet 32 ​​to move, and the spacing between the inclined pallet 32 ​​changes in the same way.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
