Description

Technical Field

[0001] The present invention relates to the technical field of logistics and cargo transportation, and in particular to a logistics and cargo transportation tool. Background Art

[0002] With the development of Internet technology and infrastructure, logistics and transportation are developing rapidly, which not only meets the needs of people's daily life, but also greatly promotes production communication and production efficiency. In order to meet the large demand for waybills, logistics and transportation are usually carried out in the form of warehouses.

[0003] At present, in order to reduce labor costs and improve cargo transportation efficiency, AGV vehicles are usually used in conjunction with shelves to transport goods. However, conventional AGV vehicles can only perform simple lifting when transporting shelves, and the plane direction of the shelves lacks corresponding limit blocks, which can easily cause sliding or tipping due to external influences during transportation, which is not conducive to the stable transportation of goods.

[0004] A logistics cargo transportation equipment with publication number CN117184713A, through the setting of a limit mechanism, can automatically limit the plane direction of the shelf through the lifting action when the shelf is lifted for transportation, so as to achieve the effect of stable transportation and prevent it from sliding or tipping over due to external influences; further, through the setting of a positioner, it can also be adapted to the use of shelves with different length and width ratios to meet the stable transportation needs of different shelves, and no additional electronic control components or detection components are required, so as to meet the stable and effective transportation needs.

[0005] In the above technical solution, the height, position and angle of the load-bearing components of the transfer trolley cannot be quickly adjusted as needed, and the goods cannot be effectively and quickly transferred, which affects work efficiency, so improvements are needed. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a logistics cargo transportation tool.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: A logistics cargo transportation tool comprises a chassis, an automatic moving mechanism is installed on the chassis, a lifting and adjusting mechanism is arranged inside the chassis, and a first supporting plate is arranged on the lifting and adjusting mechanism; The first supporting plate is provided with a first supporting groove, a pulling mechanism is provided in the first supporting groove, and a bearing frame is installed on the pulling mechanism; A U-shaped moving frame is slidably mounted on the carrier frame, first notches are arranged on both sides of the U-shaped moving frame, the carrier frame is located between the two first notches, a linkage mechanism is arranged in the first notch, a sliding frame is arranged on the linkage mechanism, and the two sliding frames are slidably mounted in the two first notches respectively; Coaxial pushing mechanisms are provided on the opposite side walls in the first supporting groove, and two first synchronous plates and two second synchronous plates are provided on the coaxial pushing mechanism. The two first synchronous plates are located between the two second synchronous plates, and the upper ends of the two first synchronous plates are commonly fixed to the lower end of the supporting frame, and the two ends of the two second synchronous plates are respectively fixed to both sides of the lower end of the supporting frame.

[0008] Compared with the prior art, the present application can realize automatic movement so that the base frame can move, and can push the first support plate to lift and rotate to adapt to the positions of different logistics goods. At the same time, it also enables the load-bearing frame, U-shaped mobile frame and sliding frame to be retracted and can be quickly plugged into the lower end of the logistics goods for rapid transfer and delivery to the corresponding position. At the same time, it can also be placed in a suitable position as needed to improve transportation efficiency.

[0009] Preferably, the coaxial pushing mechanism includes four second synchronous wheels rotatably connected to opposite side walls in the first supporting groove, a second synchronous belt is commonly sleeved between two second synchronous wheels located on the same side, the pulling mechanism is located between the two second synchronous belts, the second synchronous belt is arranged parallel to the length direction of the first supporting groove, a first synchronous wheel is fixed to one side of the second synchronous wheel, the first synchronous wheel and the second synchronous wheel fixed thereto are arranged coaxially, a first synchronous belt is commonly sleeved between two first synchronous wheels located on the same side, the two first synchronous belts are located between the two second synchronous belts, two first synchronous plates are respectively fixed to the upper ends of the two first synchronous belts, and two second synchronous plates are respectively fixed to the upper ends of the two second synchronous belts.

[0010] Furthermore, when the carrier moves under the action of the pulling mechanism, the carrier can drive the first synchronous belt to move through the first synchronous plate. As the first synchronous belt moves, the first synchronous wheel can drive the second synchronous wheel to rotate. At the same time, the first synchronous wheel and the second synchronous wheel rotate coaxially, so that the second synchronous wheel and the first synchronous wheel have the same rotation angular velocity, but the second synchronous wheel has a rotation linear velocity greater than the first synchronous wheel, so that the second synchronous belt drives the second synchronous plate to move faster, and the second synchronous plate drives the U-shaped movable frame to move, so that the moving speed of the U-shaped movable frame can be faster than the moving speed of the carrier, which facilitates the movement of the U-shaped movable frame and the carrier relative to the first support plate.

[0011] Preferably, the pulling mechanism comprises a telescopic hydraulic assembly fixed in the first supporting groove, and the piston rod end of the telescopic hydraulic assembly is fixedly connected to the lower end of the supporting frame.

[0012] Furthermore, the operation of the telescopic hydraulic assembly enables the piston rod of the telescopic hydraulic assembly to operate, and the contraction of the piston rod of the telescopic hydraulic assembly can cause the support frame to move away from the mounting frame. When the piston rod of the telescopic hydraulic assembly extends, the support frame can move toward the mounting frame.

[0013] Preferably, slide grooves are provided on both sides of the carrier frame, and sliders are installed in the slide grooves. One side of the two sliders are respectively fixed on the opposite side walls in the U-shaped movable frame. A slide rod is fixed at one end of the slider. One end of the slide rod passes through the slide groove and extends to one side of the U-shaped movable frame. One end of the slide rod extends out of the carrier frame and is fixedly connected to the U-shaped movable frame.

[0014] Furthermore, the slide groove is arranged in the length direction of the supporting frame, so that the slider moves along the direction of the slide groove, and as the slider moves, the slide rod will be driven to move synchronously with the slider. The slide rod can push the U-shaped moving frame to move, so as to fully ensure that the U-shaped moving frame moves relative to the supporting frame.

[0015] Preferably, the linkage mechanism includes a second notch opened at the lower end of the first notch, and limiting grooves are opened on both sides of the sliding frame, and limiting blocks are installed in the limiting grooves. The two limiting blocks are respectively fixed on the opposite side walls in the first notch, and a rotating shaft is rotatably sleeved in the second notch. A pull rope is sleeved on the rotating shaft, and the lower end of the pull rope is fixedly connected to the first support plate, and the upper end of the pull rope is fixed to the lower end of the sliding frame, and a tension spring is commonly fixed between the sliding frame and the first notch.

[0016] Furthermore, the limit block is fixedly connected to the side wall in the first notch, which can ensure a firm connection between the limit block and the U-shaped movable frame. At the same time, the limit block extends into the limit groove, which can ensure the stability of the movement of the sliding frame. At the same time, when the U-shaped movable frame moves in a direction away from the mounting frame, the pull rope will pull the sliding frame to separate from the U-shaped movable frame more quickly, which can improve the efficiency of the extension and retraction of the supporting frame, the U-shaped movable frame and the sliding frame, and when the supporting frame moves in the direction of the mounting frame, the sliding frame can be reset by pulling the tension spring.

[0017] Preferably, the automatic moving mechanism comprises a mounting frame fixed to one side of the base frame, a climbing staircase assembly is mounted on the side of the mounting frame away from the supporting frame, and an automatic moving assembly is mounted on the lower end of the base frame.

[0018] Furthermore, the automatic moving component is an adjustable moving component, which can adopt a wheel structure or a crawler structure for easy movement. At the same time, the climbing stair component can be set as a component with a climbing stair function, which can improve the adaptability of the equipment.

[0019] Preferably, the lifting and lowering adjustment mechanism comprises a third support plate fixed in the base frame, a third support groove is formed at the upper end of the third support plate, a lifting hydraulic assembly is fixed at the bottom of the third support groove, a lifting plate is fixed on the piston rod of the lifting hydraulic assembly, damping assemblies are fixed at the four corners of the lifting plate, the piston rod of the damping assembly is fixed to the lower end of the second support plate, a resistance spring member is sleeved on the piston rod of the damping assembly, and the upper and lower ends of the resistance spring member are respectively fixed to the lower end of the second support plate and the upper end of the lifting plate; The four corners of the third support plate are fixed with columns, and the four columns are slidably installed on the four corners of the lower end of the second support plate. The end of the piston rod of the push-up hydraulic assembly is connected to a rotating mechanism, which is arranged on the second support plate and connected to the first support plate.

[0020] Furthermore, during actual production and preparation, the column is slidably installed in the second support plate, so that the second support plate can be lifted and lowered relative to the column, and by setting the structure of the column and the second support plate, after the second support plate rises to a certain position, it cannot continue to rise under the action of the column, that is, the operation of the lifting hydraulic component can make the piston rod of the lifting hydraulic component operate, and the piston rod of the lifting hydraulic component can drive the lifting plate to rise, so that the lifting plate drives the damping component and the resistance spring part thereon to push the first support plate to rise, and after rising to the point where the second support plate cannot rise anymore, the piston rod of the lifting hydraulic component can continue to operate, thereby facilitating the operation of the rotating mechanism.

[0021] Preferably, the rotating mechanism includes a second supporting groove opened on the second supporting plate, a screw nut is rotatably sleeved at the bottom of the second supporting groove, the lower end of the screw nut extends to the lower end of the second supporting plate, a screw is threadedly sleeved on the inner thread of the screw nut, and a second turntable is rotatably sleeved on the upper end of the screw, a vertical axis is commonly provided through the second turntable and the screw, and the upper end of the vertical axis is rotatably sleeved on the first turntable, the upper ends of the first turntable and the screw nut are both fixed to the lower end of the first supporting plate, the vertical axis sleeve is provided with an extrusion spring, the upper and lower ends of the extrusion spring are respectively fixed on the opposite sides of the first turntable and the second turntable, and the lower end of the screw is fixed to the end of the piston rod of the lifting hydraulic assembly.

[0022] Furthermore, when the second support plate rises to a position where it cannot rise any further, the hydraulic push assembly continues to extend so that the hydraulic push assembly pushes the lead screw to rise, and the rise of the lead screw causes the lead screw nut to rotate, and the rotation of the lead screw nut can drive the first support plate to rotate.

[0023] Preferably, the U-shaped moving frame and the sliding frame are arranged obliquely at one end away from the supporting frame.

[0024] Furthermore, through the inclined ends of the U-shaped mobile frame and the sliding frame, the U-shaped mobile frame and the sliding frame can be easily inserted into the lower end of the corresponding logistics goods, which is convenient for subsequent lifting and transportation.

[0025] Preferably, fixing plates are fixed on both sides of the U-shaped movable frame.

[0026] Furthermore, the U-shaped movable frame and the fixed plate are formed in one piece to ensure the supporting strength.

[0027] The beneficial effects of the present invention are: 1. Automatic movement can be achieved through the setting of automatic moving components and climbing stair components, which helps to improve work efficiency and can adapt to various operating environments; 2. The operation of the telescopic hydraulic assembly can make the piston rod of the telescopic hydraulic assembly telescopic, and the carrier can be moved relative to the first support plate and the base frame. The movement of the carrier can make the first synchronous belt operate through the first synchronous plate to drive the first synchronous wheel and the second synchronous wheel to rotate, and the second synchronous plate is driven to move through the second synchronous belt. At the same time, in actual production and preparation, the second synchronous belt, the second synchronous wheel, the first synchronous belt and the first synchronous wheel are all toothed structures, the tooth shapes of the second synchronous belt and the second synchronous wheel correspond, and the tooth shapes of the first synchronous belt and the first synchronous wheel correspond, which can ensure the stability of the transmission; 3. The second synchronous wheel is coaxially arranged with the first synchronous wheel fixed thereto, and the diameter of the second synchronous wheel is larger than the diameter of the first synchronous wheel, which makes the rotation angular velocity of the first synchronous wheel and the second synchronous wheel the same, the rotation linear velocity of the first synchronous wheel is slower than the rotation linear velocity of the second synchronous wheel, and the moving speed of the first synchronous plate is slower than the moving speed of the second synchronous plate, which makes the moving speed of the U-shaped moving frame faster than the moving speed of the carrier frame; 4. When the U-shaped moving frame moves, the U-shaped moving frame will drive the rotating shaft to move, which will cause the rotating shaft to push the pull rope to operate, so that the pull rope drives the sliding frame to move relative to the U-shaped moving frame. This will cause a speed difference between the U-shaped moving frame and the load-bearing frame when the load-bearing frame moves, so that the U-shaped moving frame moves a longer distance; The speed difference between the sliding rack and the U-shaped mobile rack causes the sliding rack to move farther than the U-shaped mobile rack, so that the load-bearing rack, the U-shaped mobile rack and the sliding rack can be extended quickly and inserted into the lower end of the logistics goods; 5. The second support plate is slidably installed between the column and the second support plate, and the second support plate can rise relative to the column. At the same time, the second support plate cannot continue to rise after it rises to a certain distance through the action of the column. The position height of the second support plate is fixed. When in use, the second support plate can be raised to the maximum height first without raising the second support plate to the maximum height. The first support plate and the second support plate can be raised first, and the U-shaped moving frame and the sliding frame can be extended to the lower end of the corresponding logistics goods. When the U-shaped moving frame and the sliding frame are inserted, the second support plate continues to rise to a suitable height to lift the logistics goods. When the U-shaped moving frame and the sliding frame are reset, the logistics goods are moved to the upper end of the bottom frame; 6. After the second support plate cannot rise, the piston rod of the hydraulic assembly can continue to rise, and the piston rod of the hydraulic assembly can push the lead screw to rise, so that the lead screw drives the lead screw nut to rotate in a directional manner, and the lead screw nut drives the first support plate to rotate, so as to facilitate adjusting the direction of the first support plate; 7. When placing goods, the load-bearing frame, U-shaped mobile frame and sliding frame are extended to move the goods to the placement position, and the second support plate and the first support plate are lowered to place the logistics goods in the appropriate position, and then the second support plate and the first support plate are lowered to facilitate the recovery of the load-bearing frame, U-shaped mobile frame and sliding frame to complete the transportation of goods.
