[0026] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] Example 1
[0028] Combined with appendix Figure 1-6 A small forklift carrying mechanism is disclosed. The loading structure is used to transport individual boxes. The box has an open structure and is directly installed on the chassis of a truck used for loading goods. The chassis 1 includes a chassis 1. Several moving structures 2 are provided on the chassis 1. The moving structures 2 are used to move the boxes placed on the truck to a suitable placement position, thereby making full use of the truck's loading space. The several moving structures 2 are arranged in sequence and are independent of each other and will not affect each other.
[0029] The movable structure 2 includes several bearing seats 21 mounted on the base 1. The bearing seats 21 are arranged in multiple rows on both sides of the chassis 1. Movable shafts 22 are rotatably mounted on the bearing seats 21. Multiple movable shafts 22 are mounted on the multiple rows of bearing seats 21. Drive wheels 23 are fixed at both ends of the movable shafts 22. A drive motor 25 is fixed on the chassis 1. A drive sprocket 251 is mounted on the output shaft of the drive motor 25. Each movable shaft 22 is equipped with a driven sprocket 26 corresponding to the drive sprocket 251. A transmission chain connects the drive sprocket 251 and the driven sprockets 26 on the multiple movable shafts 22. The multiple movable shafts 22 in each movable structure 2 are connected to the same transmission chain. The drive motor 25 drives the transmission chain to rotate, thereby driving the multiple movable shafts 22 inside the movable structure 2 to rotate. The rotation of the movable shafts 22 causes the drive wheels 23 mounted on the movable shafts 22 to rotate. The rotation of the drive wheels 23 can directly transport the box loaded on the truck, moving the box from the rear of the truck's swing arm to the front of the truck's swing arm and placing it in sequence.
[0030] The distance between adjacent moving structures 2 is less than the length of the loading swing arm truck, so that when the drive wheels 23 of adjacent moving structures 2 rotate, the box that needs to be transported across different moving structures 2 can be supported and driven by the drive wheels 23 of the two adjacent moving structures 2, preventing the box from being poorly supported on both sides or having insufficient driving force during the movement.
[0031] The movable structure 2 is also equipped with a placement frame 27 located on the upper side of the movable shaft 22 and the drive wheel 23. The placement frame 27 is used to support the box body. The placement frame 27 is composed of a metal frame structure. One side of the placement frame 27 is rotatably mounted on the chassis 1, so that the placement frame 27 can be tilted to the side of the truck. A connecting frame 28 is fixedly provided on the chassis 1. One side of the placement frame 27 is provided with a rotating ear 29 that rotatably cooperates with the connecting frame 28. A rotating shaft 281 is hinged between the rotating ear 29 and the connecting frame 28. The placement frame 27 rotates around the rotating shaft 281. An insertion frame 30 is fixedly provided on the other side of the placement frame 27. A limiting block 31 is fixedly provided on the chassis 1 on the same side as the insertion frame 30. The limiting block 31 has an upward opening structure. The position and size of the insertion frame 30 correspond to the position and size of the limiting block 31. The insertion frame 30 is inserted into the limiting block 31. The opening of the limiting block 31 is designed to expand outward to facilitate the entry of the insertion frame 30, so that the placement frame 27 forms a stable support structure.
[0032] A lifting hydraulic rod 30 is hinged to the chassis 2. The hydraulic cylinder of the lifting hydraulic rod 30 is hinged to the chassis 2. The support rod of the hydraulic rod 30 is connected to the placement frame 27. The hydraulic rod 30 extends by driving the support rod, thereby enabling the placement frame 27 to flip towards the side of the truck.
[0033] The placement rack 27 is also equipped with a locking cylinder 31. The locking cylinder 31 has pins 32 fixed at both ends. The locking cylinder 31 consists of two hydraulic rods fixed on the placement rack 27. The hydraulic cylinders of the two hydraulic rods are symmetrically fixed on the placement rack. The support rods of the two hydraulic rods face the two sides of the placement rack 27 respectively. The support rods facing the two sides are fixedly connected to the pins 32. When the hydraulic rod drives the support rod to extend, the hydraulic rod drives the pin to extend out of the placement rack 27. The pin 32 is inserted into the box with the insertion hole, thereby fixing the box to the placement rack 27 through the pin 32.
[0034] When the placement rack 27 is not loaded with a box or when a box needs to pass through the placement rack 27, the hydraulic rod forming the locking cylinder 31 retracts the support rod into the hydraulic cylinder. Simultaneously, the support rod drives the pin 32 to retract into the placement rack 27, facilitating the passage of the box. When a box is loaded onto the placement rack 27, the hydraulic rod forming the locking cylinder 31 extends the support rod, which drives the pin 32 to insert into the insertion hole of the box, firmly fixing the box to the placement rack 27. A cover plate is provided on the top surface of the placement rack 27 to cover the internal structure of the placement rack 27, preventing exposed components from causing injury to workers. In other embodiments, the locking cylinder 31 is a bidirectional hydraulic rod with support rods extending in two directions at both ends, and the pin 32 is fixed on the support rods of the bidirectional hydraulic rod.
[0035] A swing arm structure 4 is provided at the end of the chassis 2 of the truck. The swing arm structure 4 is used to lift the box on the ground and transport it to the mobile structure 2. The swing arm structure 4 is a symmetrical structure and is respectively set on both sides of the chassis 1. The swing arm structure 4 includes a swing hydraulic rod 41. A swing hydraulic rod support seat 42 is fixed on the chassis 1. A swing arm 43 is hinged to the end of the chassis 1. An installation block 44 is fixed to the upper end of the swing arm 43. The hydraulic cylinder end of the swing hydraulic rod 41 is hinged to the swing hydraulic rod support seat 42. The support rod of the swing hydraulic rod 41 is hinged to the installation block at the end of the swing arm 43. The swing hydraulic rod 41 drives the swing arm 43 to swing through the drive support rod.
[0036] A first connecting beam 45 and a second connecting beam 46 are fixedly provided between the mounting blocks 44 at the upper ends of the swing arms 43 on both sides. The first connecting beam 45 and the second connecting beam 46 are arranged side by side. The first connecting beam 45 and the second connecting beam 46 can reinforce the swing arm structure 4 on both sides. At the same time, the swing hydraulic rods 41 on both sides work together to make the first connecting beam 45 and the second connecting beam 46 swing with the swing arms 43 on both sides. The two ends of the second connecting beam 46 are provided with a drive plate 47, which can rotate on the second connecting beam 46. The second connecting beam 46 has a locking plate inside the drive plate 47 to prevent the drive plate 47 from moving. The drive plate 47 has an opening 48 for installing a lifting chain. One side of the drive plate 47 has two openings 48, and a chain is installed in each opening 48. The chain has hooks for hooking the four corners of the box.
[0037] A bolt sleeve 49 is fixedly installed on the mounting block 44 between the first connecting beam 45 and the second connecting beam 46. The bolt sleeve 49 is provided with an abutment bolt 50. The abutment bolt 50 is provided with a fixing nut 51 on both sides of the bolt sleeve 49. The abutment bolt 50 abuts against the drive plate 57. By adjusting the position of the abutment bolt 50, the drive plate 57 is deflected to different angles, thereby further controlling the angle of the chain and hook installed on the drive plate 57 so that the chain and hook can be adapted to different boxes.
[0038] A motor mounting plate 58 is also fixedly installed on the second connecting beam 46. An electric angle plate 59 is fixedly installed on the motor mounting plate 58. An iron cable 60 is installed on the electric angle plate 59, and a hook is also installed on the iron cable 60. The electric angle plate 59 can assist in pulling some smaller components. A baffle is provided on the motor mounting plate 58 to protect the electric angle plate 59 from rain and dust.
[0039] A trailer mounting frame 6 is provided on the rear side of the chassis 1. The trailer mounting frame 6 is used to place the trailer 61. The trailer mounting frame 6 includes a slide rail 62 fixed on the chassis 1. A slide beam 63 is slidably provided in the slide rail 62. A limiting plate 64 and a stop shaft 65 are provided on the inner side of the upper surface of the slide beam 63. A rear baffle 66 is fixed on the outer side of the upper surface of the slide beam 63. A front baffle 67 is fixed on the inner side of the slide rail 62. A side baffle 68 is also provided on the side of the slide rail 62. A trailer wheel support baffle 69 is also provided on the slide rail 62. The limiting plate 64 and the stop shaft 65 cooperate with the front baffle 67 to limit the outriggers on the inner side of the trailer 62 and prevent the trailer 61 from moving back and forth. The trailer 61 is locked into the side baffle 68 to prevent the trailer 61 from moving left and right. The steering wheels of the trailer 61 are fixed on the trailer wheel support baffle 69 to prevent uneven weight distribution and tilting. At the same time, the rear baffle 66 further prevents the trailer 61 from falling off. When a trailer is mounted on the trailer mounting rack 6, it can limit the trailer 61 from all directions, preventing it from moving. The electric angle tray 59 can lift the trailer via its cable 60 and hook, making it easy to load and unload the trailer 62 from the trailer mounting rack 6. It is easy to use.
[0040] In use, first activate the electric cornering plate 59 to remove the trailer 61 from the trailer mounting bracket 6, and control the swing hydraulic rod 41 to move the trailer 61 to a suitable position. Then, control the electric cornering plate 59 to lower the trailer 61, allowing the worker to operate the trailer to move the container to be transported to the end of the truck.
[0041] The worker operates the swing hydraulic rod 41 to swing the swing arm 43 to the rear of the box, and moves the second connecting beam 46 to the upper side of the box. The worker adjusts the relative position of the abutment bolt 50 and the bolt sleeve 49 according to the size and position of the box, so that the abutment bolt 50 changes the deflection angle of the drive plate 57 by abutting against the drive plate 57. The abutment bolt 50 is fixed to the relative position of the abutment bolt 50 and the bolt sleeve 49 by the fixing nut 51. The angle of the drive plate 57 is adjusted according to the position and size of the box, so that the chain and hook installed on the drive plate 57 are in the optimal position to hook the box.
[0042] After the chain and hook on the drive plate 57 hook the box, the worker operates the swing hydraulic rod 41 again to swing the swing arm 43 to one side of the moving structure 2 until the box is placed on the moving structure 2 that is closest to the swing structure. At this time, the box is located on the drive wheel 23.
[0043] The worker turns on the drive motor 25, which drives the drive wheel 23 to rotate via the driven chain. The rotation of the drive wheel 23 causes the box to move, moving the box to the innermost placement rack 27 on the truck chassis. At this time, the locking cylinder 31 on the placement rack 27 drives the pin 32 to extend. The pin 32 is inserted into the insertion hole of the box to fix the box to the placement rack 27.
[0044] Meanwhile, when it is necessary to unload the goods inside the container, the worker controls the support rod of the lifting hydraulic rod 30 to extend, and the placement frame 27 will drive the container to tilt to one side of the truck in sync, at which time the items inside the container can be poured out directly.
[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
