Technical Field

[0001] The present invention relates to the field of transportation technology, and in particular to a road freight transportation unloading platform and a use method thereof. Background Art

[0002] The unloading platform is an important facility for the delivery vehicle to unload the goods from the vehicle to the platform. During the road freight transportation process, the truck needs to complete the unloading operation of the goods through the unloading platform so that the goods can be smoothly removed from the vehicle.

[0003] The unloading platform has a height adjustment function when in use. The platform adjusts the height of the supporting surface of the truck compartment to load and unload goods. However, the specifications of the goods transported in the compartment are different. When the width of the goods is large, the baffles on both sides of the platform will affect the transportation of the goods. The use of unloading platforms of various specifications increases the production cost. Therefore, those skilled in the art provide a road freight transport unloading platform and a method of using the same to solve the problems raised in the above background technology. Summary of the invention

[0004] The purpose of the present invention is to address the problems existing in the background technology and to provide a road freight transport unloading platform and a method of using the same.

[0006] Preferably, the front and rear ends of the thread are both provided with a fixing plate connected to the rotating seat 1, and a fixing plate is provided between the rotating seat 2. The rotating seat 1 and the rotating seat 2 are connected by the fixing plate to form four synchronously moving modules.

[0007] Preferably, the inner wall of the fixed plate is provided with a slide groove, the upper end of the bottom frame and the lower end of the lifting platform are provided with symmetrically distributed guide rails, and the slide groove is slidably sleeved on the outer wall of the guide rail. The slide groove is slidably supported on the outer wall of the guide rail, and is slidably guided by the slide groove when the fixed plate moves.

[0008] Preferably, rivet 1 is rotatably installed between the mounting seat 1 and the rotating arm 1 and the rotating arm 2, rivet 2 is rotatably installed between the mounting seat 2 and the rotating arm 1 and the rotating arm 2, and rivet 3 is rotatably installed at the intersection of the rotating arm 1 and the rotating arm 2. The rotating arm 1 and the rotating arm 2 are rotatably supported with the rotating seat 1, the rotating seat 2 and the intersection with each other by rivet 1, rivet 2 and rivet 3.

[0009] Preferably, a guide plate is provided at one end of the lifting platform, the guide plate is inclined, and the upper end of the guide plate is away from the travel plate and the height gradually decreases. The guide plate guides the bottom of the forklift equipment through the inclination, and the forklift moves effectively on the lifting platform and the ground.

[0010] Preferably, the upper end of the guide plate 1 is attached with a stroke plate 2, the stroke plate 2 has the same inclination as the upper end of the guide plate, and one end of the stroke plate 2 is connected to the stroke plate 1. When the stroke plate 1 moves, the stroke plate 2 is driven to move, and at the same time, the guide plate and the stroke plate 2 have the same inclination, and the guide plate effectively supports the lower end of the stroke plate 2.

[0011] Preferably, the bottom frame is provided with symmetrically distributed rotating seats, and pulleys are rotatably mounted at the front and rear ends of the rotating seats. The pulleys are rotatably supported by the rotating seats.

[0012] Preferably, a mounting plate is arranged between the rotating seats, and symmetrically distributed hydraulic rods are arranged inside the upper end of the bottom frame, and the telescopic ends of the hydraulic rods are connected to the upper ends of the mounting plates.

[0014] Preferably, the steps for using the unloading platform are as follows:

[0015] S1: The bottom frame is the bottom support of the unloading platform. During the movement, it is used in conjunction with a pulley that can roll on the ground. The hydraulic rod drives the mounting plate to descend, driving the rotating seat and the pulleys at both ends of the rotating seat to move longitudinally, and making the pulleys fit the ground. The bottom of the equipment is supported by rolling, making it easier to transport the equipment during movement.

[0016] S2: With the cooperation of the rotating arm 1 and the rotating arm 2 which are cross-distributed and rotatably installed inside the mounting seat 1 and the mounting seat 2, and the screw rods with relatively distributed outer wall threads and the symmetrically distributed nut structures, when the shear force provided by the rotating arm 1 and the rotating arm 2 acts on the slidingly installed mounting seat 1 and the mounting seat 2, the height of the lifting platform is adjusted, so that in the process of road cargo transportation, the unloading platform effectively corresponds to the height of the car support surface to transfer the cargo.

[0017] S3: It is worth mentioning that the upper end of the lifting platform is provided with a symmetrically distributed guide plate 1 and a guide plate 2 connected to the guide plate 1. With the cooperation of the tooth plate and the gear, the guide plate 1 and the guide plate 2 are driven to move relative to or away from each other. When the width of the packaged goods is large, the width of the lifting platform can be adjusted to adapt to the passage of forklifts and goods of different widths, thereby improving the flexibility of use.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The height of the present invention is adjusted by the lifting platform. When it is adjusted to the same height as the supporting surface of the truck compartment, an automatic or manual forklift can pass through effectively. After the goods are inserted into the compartment, the height of the lifting platform is adjusted to transfer the goods. A travel plate that can move relative to or away from each other is provided on the upper end of the lifting platform for unloading. The travel plate is used to directly support the bottom of the forklift. The width of the lifting platform is adjusted to suit the width of different packaged goods, thereby avoiding the purchase of multiple types of unloading platform devices, reducing the cost of use, and improving the flexibility of the unloading platform device during use.

[0032] A fixing plate 28 connected to the rotating seat 24 1 is provided at both the front and rear ends of the thread, and a fixing plate 28 is provided between the rotating seats 24 2;

[0033] The inner wall of the fixed plate 28 is provided with a slide groove, and the upper end of the bottom frame 7 and the lower end of the lifting platform 3 are provided with symmetrically distributed guide rails 19, and the slide groove is slidably sleeved on the outer wall of the guide rail 19;

[0034] A rivet 16 is rotatably installed between the mounting seat 1 6 and the rotating arm 1 4 and the rotating arm 2 5, a rivet 2 17 is rotatably installed between the mounting seat 2 8 and the rotating arm 1 4 and the rotating arm 2 5, and a rivet 3 18 is rotatably installed at the intersection of the rotating arm 1 4 and the rotating arm 2 5;

[0035] The bottom frame 7 is provided with symmetrically distributed rotating seats 24, and pulleys 25 are rotatably mounted at the front and rear ends of the rotating seats 24;

[0036] A mounting plate 26 is provided between the rotating seats 24, and symmetrically distributed hydraulic rods 27 are provided inside the upper end of the bottom frame 7, and the telescopic ends of the hydraulic rods 27 are connected to the upper end of the mounting plate 26;

[0037] In this embodiment, the hydraulic rod 27 drives the mounting plate 26 to descend, and the hydraulic pressure of the hydraulic rod 27 causes the pulley 25 to release contact with the ground and support the lower end of the bottom frame 7, and the unloading platform is pushed by the pulley 25, so that the unloading platform is moved to the rear of the truck compartment, and a manual forklift or a mobile forklift moves to the unloading platform. The forklift is guided by the guide plate 2 and moves from the ground to the lifting platform 3. The forklift is supported at the bottom on the unloading platform by the travel plate 1 11 and the travel plate 2 12. When the forklift is lifted to the height of the support surface of the truck compartment, the forklift inserts and takes out the goods inside the compartment, and moves back and forth on the lifting platform 3, and the road goods are transferred by adjusting the height of the lifting platform 3;

[0043] Baffles 1 are provided at both ends of the travel plate 2 12 and the travel plate 1, symmetrically distributed positioning holes 13 are provided inside the lifting platform 3, and positioning rods 14 are symmetrically distributed and slidably installed on the inner wall of the positioning holes 13 at the opposite ends of the side plates 9;

[0044] In this embodiment, the motor 2 15 drives the gear 21 to rotate, pushing the tooth plate 20, and then driving the tooth plate 20 to move relative to or away from each other, and the side plate 9 follows its movement, driving the travel plate 1 11 and the travel plate 2 12 to move synchronously, and driving the baffle 1 to move. The baffle 1 protects both sides of the goods during transportation to prevent the goods from falling off. At the same time, the widened lifting platform 3 is convenient for the passage of forklifts and goods of different widths, avoiding the problem of needing to replace the unloading platform when loading and unloading goods on the road because the forklift is wider or the goods are wider. By adjusting the width of the unloading platform itself, flexible loading and unloading of road goods can be achieved.
