Abstract
Description
Technical Field
[0001] This utility model relates to the field of loading and unloading technology for truck bodies, specifically a truck body. Background Technology
[0002] A truck bed is the part of a vehicle used to load goods onto the truck and transport them. Truck beds typically have a closed or semi-closed structure to ensure that goods arrive at their destination safely and efficiently. Truck beds are widely used in the logistics and transportation industries.
[0003] When loading goods onto a truck, workers typically need to enter the truck bed and move the goods back and forth into the bed before stacking them neatly from the inside out. When unloading, the process is the same: after removing the goods near the door from the outside in, workers need to enter the truck bed and move the goods back and forth to complete the unloading. However, this method results in slow loading and unloading efficiency, leading to longer loading and unloading times and a heavy workload for workers due to the need to enter the truck bed and move the goods back and forth.

[0022] 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.
[0023] Please see Figure 1 In this embodiment, a freight car body includes a main body 1. The left side wall of the main body 1 is connected to a door by a hinge. A monitor 2 is fixed on the top of the inner cavity of the main body 1. The interior of the main body 1 is provided with a transport structure.
[0024] Please see Figures 1 to 5 In this embodiment, the transport structure includes a frame 31 fixed inside the carriage body 1. A conveying mechanism 32 is fixed to the inner side of the frame 31. A baffle 33 is fixed to the top of the conveying mechanism 32. Guide rails 310 are fixed to both the front and rear ends of the top of the frame 31. A tensioning mechanism for tensioning its conveyor belt is provided on the lower side of the conveying mechanism 32. The tensioning mechanism includes the frame 31 fixed to the lower side of the conveying mechanism 32 and a mounting frame 331 fixed to the lower surface of the conveying mechanism 32. A worm gear reducer motor 332 is fixed to the inner bottom wall. A drive wheel 333 is fixed to the outer side of the output shaft of the worm gear reducer motor 332. Three shafts 334 are rotatably connected between the inner walls of the front and rear sides of the mounting bracket 331 through bearings. Rollers 335 are fixed to the outer side of each of the three shafts 334. Sprockets 336 are fixed to the outer side of both the shafts 334 and the outer side of the worm gear reducer motor 332. The two are connected by chain drive. The transport structure also includes an anti-drop structure set inside the main body 1 of the carriage.
[0025] The left and right walls of the inner cavity of the carriage body 1 are fixed with rubber sheets, the width of which is 35-40 mm. The opposite sides of the two rubber sheets abut against the front and rear walls of the frame 31, respectively. The rubber sheets at both ends can seal the gap between the inner cavity wall of the carriage body 1 and the frame 31, so as to prevent dust.
[0026] In addition, the baffle 33 is T-shaped so that it can contact the top of the frame 31 while also contacting the conveying mechanism 32, thus ensuring its stability. Slider blocks are fixed on both the left and right sides of the lower end of the baffle 33. The sliders are slidably connected to the inside of the guide rail 310, so that the two ends of the baffle 33 that contact the frame 31 can move smoothly on the frame 31.
[0027] In addition, the inner walls of the front and rear sides of the mounting bracket 331 are provided with sliding grooves 337. The lower shaft 334 is linearly connected to the inner wall of the sliding groove 337 and fixed by bolts. The conveying mechanism 32 is connected to the three drive wheels 333 through the same belt drive, so that the lower shaft 334 can move left and right, which can adjust the tension of the conveyor belt of the conveying mechanism 32, and it is fixed in the moving hole by bolts.
[0028] Please see Figure 1 , Figure 4 and Figure 5 The anti-fall structure in this embodiment includes an anti-fall compartment 34, and a rotating rod 35 is provided at the right end of the anti-fall compartment 34. The anti-fall structure also includes a first motor 36 fixed to the front wall of the inner cavity of the carriage body 1. A rotating shaft 37 is fixed at the output end of the first motor 36. Two connecting rods 38 are fixed at both the upper and lower ends of the outer surface of the rotating shaft 37. Two support rods 39 are fixed at both the front and rear ends of the rotating rod 35.
[0029] Secondly, the right side wall of the anti-drop chamber 34 is provided with an arc groove, and the rotating rod 35 is fixed inside the arc groove, so that the rotating rod 35 can be tightly fitted and fixed together with the anti-drop chamber 34 through the arc groove, so that the rotating rod 35 can drive the anti-drop chamber 34 to flip.
[0030] In addition, the rotating rod 35 is a cylinder with a hollow interior and missing front and rear ends, and the rotating shaft 37 is rotatably connected to the interior of the rotating rod 35 so that the rotating shaft 37 can be located inside the rotating rod 35.
[0031] Furthermore, the opposing sides of the upper and lower sets of connecting rods 38 are fixed to the upper and lower walls of the inner cavity of the rotating rod 35, so that when the rotating rod 35 rotates, it drives the two sets of connecting rods 38 to rotate inside the rotating rod 35, so that the two sets of connecting rods 38 can drive the rotating rod 35 to rotate inside the carriage body 1. The first motor 36 is located inside the rotating rod 35, so that the first motor 36 can drive the rotating shaft 37 to rotate inside the rotating rod 35.
[0032] In addition, annular grooves are provided on both the front and rear walls of the inner cavity of the carriage body 1. Two support rods 39 of the same group are slidably connected inside the annular grooves. The first motor 36 is located inside the front annular groove, so that the two sets of support rods 39 can rotate on the inner cavity wall of the carriage body 1, so as to enhance the stability of the rotating rod 35 when rotating inside the carriage body 1, and to alleviate the weight borne by the first motor 36.
[0033] It should be noted that the monitor 2, the conveying mechanism 32, and the electronic components mentioned in the text are all commonly known in the prior art. Furthermore, the control method of this embodiment is controlled by a controller. All electrical components mentioned in the text are connected to the controller and the power supply. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The provision of the power supply is also common knowledge in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.
[0034] The working principle of the above embodiments is as follows:
[0035] When goods need to be placed into the main body 1 of the carriage, the conveying mechanism 32 moves the baffle 33 towards the carriage door. When the baffle 33 moves to the carriage door, the staff can place the goods on the conveying mechanism 32 and place the goods against the baffle 33. After the space is filled, the conveying mechanism 32 moves the stacked goods and the baffle 33 into the main body 1 of the carriage and repeats the above steps. Thus, the goods can be stacked and placed in the main body 1 of the carriage without the staff having to enter the main body 1 of the carriage and move and place the goods back and forth.
[0036] When the main body of the carriage 1 needs to be unloaded, the staff unloads the goods near the carriage door. The conveying mechanism 32 then moves the baffle 33 and the goods out of the main body of the carriage 1. This eliminates the need for staff to enter the main body of the carriage 1 and move the goods back and forth. Staff only need to stand at the door of the main body of the carriage 1 to pick up the goods. This can effectively improve the loading and unloading efficiency of the main body of the carriage 1, shorten the loading and unloading time, and reduce the workload of the staff.
[0037] When the main body 1 of the carriage is loading or unloading goods, the output end of the first motor 36 drives the rotating shaft 37 to rotate, which in turn drives the two sets of connecting rods 38 to rotate. The two sets of connecting rods 38 then drive the rotating rod 35 to rotate, which in turn drives the anti-drop compartment 34 to flip from left to right. This allows the anti-drop compartment 34 to flip out of the main body 1 of the carriage so that it can catch the goods that fall during loading or unloading and prevent the goods from falling to the ground.
[0038] Furthermore, when the conveying mechanism 32 is in operation, the output end of the worm gear reducer motor 332 drives the drive wheel 333 to rotate. The drive wheel 333 then drives the left shaft 334 to rotate via the sprocket 336 and the chain, allowing multiple rollers 335 to rotate. The lower shaft 334 moves within the groove 337 of the mounting frame 331, allowing the tension of the conveyor belt of the conveying mechanism 32 to be adjusted as needed.
[0039] When the main body 1 of the carriage is closed, the output end of the first motor 36 drives the rotating shaft 37 to rotate from right to left. The rotating shaft 37 can drive the rotating rod 35 to rotate through the two sets of connecting rods 38. The rotating rod 35 can then drive the anti-fall compartment 34 to flip inside the main body 1, thus avoiding obstruction to the closing of the carriage door of the main body 1.
