Description

Technical Field

[0001] The invention belongs to the field of logistics transfer, in particular to a logistics transfer device. Background Art

[0002] Logistics is an industry that involves the entire process from the place of production to the place of consumption of goods, including transportation, warehousing, packaging, distribution, logistics information management and other links. The main purpose of logistics is to ensure that goods can be safely transported from the supply point to the demand point.

[0003] Logistics transshipment refers to the process of transporting goods from a starting point to a destination through different modes of transportation and service providers. It is included in the classification of logistics transportation. For example, in the case of long-distance transportation, large trucks are used for centralized loading and transportation. When arriving at the sorting point, the goods need to be unloaded from the large trucks and distributed to small trucks according to the region for distribution.

[0004] In traditional logistics transportation, all goods need to be taken out of large trucks and received by a conveyor belt or a forklift plus a pallet combination at the end of the truck. However, since large trucks are stacked with a large number of goods of different sizes and shapes, the goods are often taken out one by one by manual transportation, which not only consumes a lot of manpower, but also has low transportation efficiency.

[0005] To this end, the present invention provides a logistics transfer equipment. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a kind of logistics transfer equipment described in the present invention comprises a plurality of material-grabbing arms, which are arranged in parallel and equidistantly, a moving seat is installed on the top of the material-grabbing arm, the material-grabbing arm is composed of an upper force arm and a lower force arm, the upper force arm and the lower force arm are rotatably connected by a door shaft, the upper force arm and the moving seat are also rotatably connected by a door shaft, a steel cable capable of controlling the bending and rotation of the upper force arm and the lower force arm is arranged on the outer side of the moving seat, the plurality of moving seats are connected in series by a sliding rod, and two driving vehicles for driving the sliding rod to move are arranged on the outer side of the sliding rod; Through the setting of the picking arm, after the truck stops, two driving vehicles are attached to the inner wall of the truck, so that the slide bar is horizontally propped up, and multiple picking arms are vertically set in the storage space of the truck. The upper force arm and the lower force arm can be controlled to bend by pulling the steel cable. The bent picking arm is located at the top, and then the picking arm is driven to move to the depth of the truck through the movement of the driving vehicle, and then the picking arm is lowered to return to the vertical shape. The bottom of the vertical picking arm is flush with the bottom surface of the truck. At this time, the driving vehicle drives the slide bar and multiple picking arms to move toward the exit, and the goods can be continuously pushed out of the truck. It only needs to use a conveyor belt or The forklift pallet combination can receive the goods. During the assembly stage of the equipment and the truck, the material-retrieving arm is folded, and the two driving carts can be placed at the lower position of the truck storage space. The driving wheels of the driving cart can be rotated at will, so that the driving cart can move arbitrarily on the inner wall of the truck. When the driving cart drives the material-retrieving arm to move upward and to the top, the material-retrieving arm is controlled to move along the direction of the truck. This setting facilitates the assembly and disassembly process of the equipment and the truck; through this setting, the function of mechanized handling of goods is realized, and the vertical material-retrieving arm can push logistics goods of various shapes. At the same time, the efficiency of pushing goods in batches is higher than that of manual handling.

[0008] Preferably, two suction cups are fixedly connected to the bottom of the lower force arm, and the openings of the suction cups face downward. A vacuum pump is fixedly connected to the middle of the lower force arm, and the negative pressure output end of the vacuum pump is connected to the two suction cups. During transportation, large trucks generally stack square goods and fill the entire storage space of the truck in order to increase the cargo volume, which makes it difficult to take the goods out during unloading. Through the setting of the suction cups, when encountering goods stacked too high, the picking arm is bent. At this time, the suction cups at the ends of the picking arm are horizontally set and facing the goods. The suction cups and the picking arm are driven by a driving vehicle to approach the top of the stacked goods, and the vacuum pump is started to generate negative pressure, thereby sucking the goods. After that, the driving vehicle controls the entire picking arm to move horizontally to drag the goods from the top of the stack outward, and then the picking arm is unbent and becomes vertical. , and turn off the negative pressure, which can not only separate some of the goods outward, but also reduce the height of the stacked goods. When the height is reduced to a certain extent, the entire equipment can be moved to the rear of the goods and push the goods to the exit as a whole, thereby effectively realizing the function of transferring the goods in the truck outward, and can deal with the problem of goods stacked too high and having no fulcrum. At the same time, when the picking arm is in a vertical state, start the vacuum pump to generate negative pressure at the bottom of the suction cup, thereby pulling the picking arm to straighten. At the same time, under the action of negative pressure, the lower force arm will be sucked to the bottom of the car box, and the upper force arm above will be restricted and cannot rotate in the opposite direction of the exit. In this way, when the picking arm is moving, the upper force arm above remains vertical, and the lower force arm below will be slightly bent, but due to the existence of negative pressure, the lower force arm fits with the bottom of the car box, thereby effectively pushing the goods to move in the direction of the exit.

[0009] Preferably, the bottom of the lower force arm is forked, and the bottom of the lower force arm is composed of two forked arms, the suction cup is fixedly connected to the bottom of the forked arm, the length of the lower force arm is greater than the length of the upper force arm, and an extrusion net is fixedly connected between the two forked arms. If the widths of the multiple lower force arms are added up to the same as the inner width of the truck, it will be difficult to observe the state of the goods at the rear during operation, which is not conducive to operation. In addition, the mass of the material-grabbing arm is too large, which will also cause the burden on the driving vehicles on both sides to be too heavy. By reducing the volume of the material-grabbing arm, the lower force arm is made forked, and the extrusion net is in a straight state. In this way, as the material-grabbing arm moves, the goods can be pushed to the exit, and the condition of the entire truck box can be observed all the time, reducing operational errors. At the same time, the forked bottom of the lower force arm allows the forked arm of the lower force arm to fully fit with the inner wall of the box, and the upper parts are not used to fit the box, which can reduce friction and use power to push the goods.

[0010] Preferably, a plurality of movable platforms are fixedly connected to the outer side of the slide bar, a support arm is fixedly connected between the plurality of movable platforms, the support arm is arranged parallel to the slide bar, both ends of the support arm are fixedly connected to the outer shell of the driving vehicle, the slide bar and the support arm are sleeved by the movable platform, and the support arm is connected to the driving vehicle at the same time, and the driving vehicle is against the inner wall of the vehicle box, thereby controlling the movement of the plurality of material picking arms.

[0011] Preferably, a reduction motor is provided at the bottom of one end of the slide bar, a screw is fixedly connected to the output end of the reduction motor, the screw passes through a plurality of moving seats and is transmission-connected to the moving seats, a connecting platform is installed between the screw and the slide bar, a connecting plate is fixedly connected between the reduction motor and the slide bar, and the screw is driven to rotate by the reduction motor, so that horizontal movement can be performed through a plurality of feeding arms. In this way, a large amount of goods can be pushed out of the vehicle body by controlling a small number of feeding arms, for example, the goods on the left side are pushed out first, and then the feeding arm is controlled to move to the right by the drive of the reduction motor to push the goods on the right out.

[0012] Preferably, a driving motor 1 is installed inside the moving seat, and a winding roller is fixedly connected to the output end of the driving motor 1, the top of the steel cable is fixedly connected to the winding roller, the steel cable passes through the bottom of the upper lever arm, and is fixedly connected to the middle part of the lower lever arm, the steel cable passes through the upper lever arm and the lower lever arm, the position where the steel cable passes through the upper lever arm is in the middle part of the upper lever arm, and the position where the steel cable and the lower lever arm are fixed is also in the middle part, as the winding roller reels the steel cable, the reeled steel cable will first rotate and bend the lower lever arm upward, and then the upper lever arm rotates, and the upper lever arm is restricted to rotate only to a horizontal state, and the final form is that the upper lever arm and the lower lever arm are stacked on each other and maintained in a horizontal state, at which time the fixed position of the steel cable and the lower lever arm coincides with the position where the steel cable passes through the upper lever arm; this is conducive to the horizontal movement of the equipment at the top inner side of the vehicle body without being blocked by cargo.

[0013] Preferably, an extension tube is fixedly connected to the middle part of the upper force arm, and the extension tube is arranged at an angle. The two ends of the extension tube are respectively exposed on both sides of the upper force arm, and the steel cable passes through the extension tube; the edges of the extension tube are arranged with smooth transitions, and the steel cable passes through the extension tube and slides in the extension tube. At the same time, the two ends of the extension tube extend outward to reduce the contact of the steel cable with the surface of the material picking arm. Because if it passes through the material picking arm directly, it will cause the steel cable to stick to the surface of the material picking arm. This can reduce the wear of the steel cable and the material picking arm.

[0014] Preferably, the bottom of the suction cup is made of elastic material, and an isolation net is fixedly connected to the bottom surface of the suction cup, and the isolation net is made of magnetic material. A blocking block is fixedly connected to the bottom of the upper force arm, and the blocking block is used to limit the rotation of the lower force arm. The suction cup fits the bottom surface of the car box. The traditional bottom surface of the car box cannot be flat. The suction cup made of flexible material can fit well with the car box, and the suction force can be adjusted by the vacuum pump to prevent the problem of insufficient driving power of the vehicle. The isolation net made of magnetic material can prevent external goods from being sucked into the suction cup. At the same time, magnetic adsorption is relied on to make the suction cup and the car box fit together, reducing the output power consumption of the vacuum pump.

[0015] Preferably, the end faces of the reduction motor and the connecting platform are rotatably connected to a plurality of metal balls, one end of the driving vehicle is connected to a traction rope, the end of the traction rope is connected to a winding box for winding and releasing the traction rope, the reduction motor and the connecting platform will contact the vehicle body, and in order to reduce friction, rolling friction between the metal balls and the inner wall of the vehicle body is used, and a driving motor 2 is arranged in the winding box, and the rotation of the driving motor 2 can wind up or release the traction rope. The winding traction rope is used to provide huge pulling force to the driving vehicle and the equipment. When encountering larger cargo, the traction rope can be used to increase the power of the equipment, and the winding box can be temporarily fixed on the outside of the vehicle body.

[0016] Preferably, the support arm is divided into multiple sections, and adjacent sections of the support arm are connected by sleeves. The support arm is fixed to the support arm by bolts. The sizes of trucks used for materials are generally the same. After the equipment is adjusted, it can be used normally. When encountering a truck that is larger in size, the distance that the support arm slides out of the sleeve can be adjusted to ensure that the driving vehicles at both ends fit the inner wall of the car body, thereby improving the applicability of the equipment. At the same time, in daily use, the overall length of the support arm can also be fine-tuned to ensure that the support arm can be firmly hung in the car body.

[0017] The beneficial effects of the present invention are as follows: 1. A logistics transfer equipment described in the present invention, through the setting of the material picking arm, after the truck stops, the two driving vehicles are attached to the inner wall of the truck, so that the sliding bar is horizontally propped up, and multiple material picking arms are vertically arranged in the storage space of the truck, and the upper force arm and the lower force arm can be controlled to bend by pulling the steel cable, and the bent material picking arm is located at the top, and then the material picking arm is driven to move to the depth of the truck through the movement of the driving vehicle, and then the material picking arm is lowered to return to the vertical shape, and the bottom of the vertical material picking arm is flush with the bottom surface of the truck. At this time, the driving vehicle can continuously push the goods out of the truck by driving the sliding bar and multiple material picking arms to move toward the exit. It is only necessary to use a conveyor belt or a forklift pallet combination outside the truck to receive the goods. Through this arrangement, the function of mechanized cargo handling is realized, and the vertical material picking arm can push logistics goods of various shapes, and the efficiency of pushing goods in batches is higher than that of manual handling.

[0018] 2. The logistics transfer equipment described in the present invention, through the setting of the suction cup, when encountering goods that are stacked too high, by bending the picking arm, the suction cup at the end of the picking arm is set horizontally and faces the goods, and the driving vehicle drives the suction cup and the picking arm to approach the top of the stacked goods, and starts the vacuum pump to generate negative pressure, thereby sucking the goods, and then the driving vehicle controls the entire picking arm to move horizontally, dragging the goods from the top of the stack outward, and then the picking arm is unbent to a vertical state, and the negative pressure is turned off, so that part of the goods can be separated outward and the height of the stacked goods can be reduced. When the height is reduced to a certain extent, the entire equipment can be moved. To the rear of the goods, and push the goods toward the exit as a whole, thereby effectively realizing the function of transferring the goods in the truck outward, and can deal with the problem of goods stacked too high and having no fulcrum.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] like Figures 1 to 5 As shown, a logistics transfer device according to an embodiment of the present invention comprises a plurality of material fetching arms 7, which are arranged in parallel and equidistantly, a movable seat 1 is installed on the top of the material fetching arm 7, the material fetching arm 7 is composed of an upper force arm 8 and a lower force arm 11, the upper force arm 8 and the lower force arm 11 are rotatably connected by a door shaft 10, the upper force arm 8 and the movable seat 1 are also rotatably connected by the door shaft 10, a steel cable 9 capable of controlling the bending and rotation of the upper force arm 8 and the lower force arm 11 is arranged on the outer side of the movable seat 1, the plurality of movable seats 1 are connected in series by a slide bar 4, and two driving vehicles 15 for driving the slide bar 4 to move are arranged on the outer side of the slide bar 4; In traditional logistics transfer, all goods need to be taken out of large trucks and received by conveyor belts or forklifts plus pallets at the end of the trucks. However, since large trucks are stacked with a large number of goods of different sizes and shapes, they are often taken out one by one by manual handling, which not only consumes a lot of manpower but also has low handling efficiency. In addition, traditional logistics packages generally include square paper-shell packaging goods and flexible packaging goods of random shapes. For transportation stability, square-shaped goods are generally stacked neatly, while flexible packaging is stacked at the exit of the truck storage space. It is difficult to transfer goods out without manual handling. In view of the above technical problems, the present invention arranges the material-grabbing arms 7. After the truck stops, two driving carts 15 are attached to the inner wall of the box, so that the slide bar 4 is horizontally propped up, and multiple material-grabbing arms 7 are vertically arranged in the box. The upper force arm 8 and the lower force arm 11 can be controlled to bend by pulling the steel cable 9. The bent material-grabbing arms 7 are located above the goods. Then, the material-grabbing arms 7 are driven to move to the depth of the box by the movement of the driving cart 15, and then the material-grabbing arms 7 are lowered to return to the vertical shape. The bottom of the vertical material-grabbing arms 7 is flush with the bottom surface of the box. At this time, the driving cart 15 drives the slide bar 4 and multiple material-grabbing arms 7 to move toward the exit, so that the goods can be continuously pushed out of the box. The goods can be received by using a conveyor belt or a forklift pallet combination outside the box; during the equipment and box assembly stage, the material-retrieving arm 7 is folded, and the two driving vehicles 15 can be placed at the lower position of the box, and the driving wheels of the driving vehicle 15 can rotate at will, so that the driving vehicle 15 can move arbitrarily on the inner wall of the box. When the driving vehicle 15 drives the material-retrieving arm 7 to move upward and top, the material-retrieving arm 7 is controlled to move along the direction of the box exit. This arrangement facilitates the assembly and disassembly process of the equipment and the box; through this arrangement, the function of mechanized handling of goods is realized, and the vertical material-retrieving arm 7 can push logistics goods of various shapes, and the efficiency of pushing goods in batches is higher than that of manual handling; It should be noted that in order for the equipment to work more smoothly, when stacking goods, it is necessary to ensure that there is a certain gap between the top and both sides of the goods and the inner wall of the cargo box. At the same time, there needs to be a certain gap between the goods so that the equipment can move smoothly to the rear of the goods, thereby pushing the goods to move.

[0028] Two suction cups 14 are fixedly connected to the bottom of the lower arm 11, and the openings of the suction cups 14 face downward. A vacuum pump 12 is fixedly connected to the middle of the lower arm 11, and the negative pressure output end of the vacuum pump 12 is connected to the two suction cups 14; During operation, in order to increase the cargo volume during transportation, large trucks generally stack square cargo and fill the entire truck box, which makes it difficult to take the cargo out during unloading. Through the setting of the suction cup 14, when encountering cargo that is stacked too high, the picking arm 7 is bent. At this time, the suction cup 14 at the end of the picking arm 7 is horizontally set and faces the cargo. The driving vehicle 15 drives the suction cup 14 and the picking arm 7 to approach the top of the stacked cargo, and the vacuum pump 12 is started to generate negative pressure, thereby sucking the cargo. Then the driving vehicle 15 controls the entire picking arm 7 to move horizontally, and the cargo is dragged out from the top of the stack. Then the steel cable 9 releases the picking arm 7. Under the action of gravity, the picking arm 7 is unbent and becomes vertical, and the negative pressure is turned off. In this way, part of the cargo can be separated outward and the height of the stacked cargo can be reduced. After moving a certain distance, the equipment is moved to the rear of the towed goods and the goods are pushed outward. When the height is lowered to a certain extent, the space above the goods is vacated, and the entire equipment can be moved to the rear of the goods and the goods are pushed toward the exit as a whole, thereby effectively realizing the function of transferring the goods in the car box outward, and can deal with the problem of goods stacked too high and having no fulcrum. At the same time, when the picking arm 7 is in a vertical state, the vacuum pump 12 is started to generate negative pressure at the bottom of the suction cup 14. Under the action of negative pressure, the lower force arm 11 will be sucked by the bottom surface of the car box, and the upper force arm 8 above will be restricted and cannot rotate in the opposite direction to the exit. In this way, during the movement of the picking arm 7, the upper upper force arm 8 remains vertical and the lower lower force arm 11 will be slightly bent. However, due to the existence of negative pressure, the lower force arm 11 fits with the bottom surface of the car box, thereby effectively pushing the goods to move toward the exit. It should be noted that, although the lower force arm 11 is sucked by the suction cup 14 and the bottom surface of the vehicle box, the driving force of the driving vehicle 15 when moving is much greater than the adsorption force of the suction cup 14, thereby smoothly pushing the movement of the goods.

[0029] The bottom of the lower force arm 11 is bifurcated, and the bottom of the lower force arm 11 is composed of two bifurcated arms 13. The suction cup 14 is fixedly connected to the bottom of the bifurcated arm 13. The length of the lower force arm 11 is greater than that of the upper force arm 8. An extrusion net 22 is fixedly connected between the two bifurcated arms 13. During operation, if the width of multiple lower force arms 11 is added up to the same as the inner width of the vehicle box, it will be difficult to observe the status of the goods at the rear during operation, which is not conducive to operation. In addition, the mass of the material-grabbing arm 7 is too large, which will also cause the burden on the driving vehicles 15 on both sides to be too heavy. By reducing the volume of the material-grabbing arm 7, the lower force arm 11 is made into a forked shape, and the extrusion net 22 is in a straight state. In this way, as the material-grabbing arm 7 moves, the goods can be pushed to the exit, and the situation of the entire vehicle box can be observed all the time, reducing operational errors. At the same time, the forked bottom of the lower force arm 11 allows the forked arm 13 of the lower force arm 11 to fully fit with the inner wall of the vehicle box, while the upper part is not used to fit with the vehicle box, which can reduce friction and is conducive to pushing the goods. The length of the lower force arm 11 is greater than that of the upper force arm 8 so that after the lower force arm 11 is bent, the suction cup 14 at the bottom can protrude outward, smoothly contact the goods and absorb and drag them.

[0030] A plurality of moving platforms 20 are fixedly connected to the outer side of the slide bar 4, and a support arm 2 is fixedly connected between the plurality of moving platforms 20. The support arm 2 is arranged parallel to the slide bar 4, and both ends of the support arm 2 are fixedly connected to the outer shell of the driving vehicle 15; During operation, the slide bar 4 and the support arm 2 are sleeved by the moving platform 20 , and the support arm 2 is connected to the driving vehicle 15 , and the driving vehicle 15 is against the inner wall of the vehicle box, so as to control the movement of the multiple material taking arms 7 .

[0031] A reduction motor 6 is arranged at the lower end of one end of the slide bar 4, a screw 5 is fixedly connected to the output end of the reduction motor 6, the screw 5 passes through a plurality of moving seats 1 and is threadedly connected to the moving seats 1, a connecting platform 3 is installed between the screw 5 and the slide bar 4, the connecting platform 3 is fixedly connected to the support arm 2, and a connecting plate is fixedly connected between the reduction motor 6 and the slide bar 4; During operation, the screw 5 is driven to rotate by the reduction motor 6, so that it can be moved horizontally through multiple feeding arms 7. In this way, a large amount of goods can be pushed out of the vehicle box by controlling a small number of feeding arms 7. A small number of feeding arms 7 also need to be arranged equidistantly. By moving the feeding arms 7 left and right, the goods in the cargo box can be pushed out in multiple times.

[0032] A driving motor 1 is installed inside the moving seat 1, and a winding roller is fixedly connected to the output end of the driving motor 1. The top of the steel cable 9 is fixedly connected to the winding roller. The steel cable 9 passes through the bottom of the upper lever arm 8 and is fixedly connected to the middle of the lower lever arm 11. During operation, the steel cable 9 passes through the upper lever arm 8 and the lower lever arm 11. The position where the steel cable 9 passes through the upper lever arm 8 is in the middle of the upper lever arm 8, and the position where the steel cable 9 and the lower lever arm 11 are fixed is also in the middle. As the winding roller reels the steel cable 9, the reeled steel cable 9 will first rotate and bend the lower lever arm 11 upward, and then the upper lever arm 8 rotates. The upper lever arm 8 is restricted to rotate only to a horizontal state. The final form is that the upper lever arm 8 and the lower lever arm 11 are stacked on each other and maintained in a horizontal state. At this time, the fixed position of the steel cable 9 and the lower lever arm 11 coincides with the position where the steel cable 9 passes through the upper lever arm 8. This is conducive to the horizontal movement of the equipment on the top inner side of the vehicle body without being blocked by cargo.

[0033] An extension tube 18 is fixedly connected to the middle of the upper lever arm 8. The extension tube 18 is arranged obliquely. Two ends of the extension tube 18 are exposed at two sides of the upper lever arm 8 respectively. The steel cable 9 passes through the extension tube 18. During operation, the edges of the extension tube 18 are all set with smooth transitions. The steel cable 9 passes through the extension tube 18 and slides in the extension tube 18. At the same time, the two ends of the extension tube 18 extend outward to reduce the contact between the steel cable 9 and the surface of the material picking arm 7. If the steel cable 9 passes through the material picking arm 7 directly, it will cause the steel cable 9 to be close to the surface of the material picking arm 7. This can reduce the wear of the steel cable 9 and the material picking arm 7.

[0034] The bottom of the suction cup 14 is made of elastic material, and an isolation net is fixedly connected to the bottom of the suction cup 14. The isolation net is made of magnetic material. A blocking block 21 is fixedly connected to the bottom of the upper force arm 8. The blocking block 21 is used to limit the rotation of the lower force arm 11. When working, the suction cup 14 fits with the bottom surface of the car box. The traditional bottom surface of the car box cannot be made flat. The suction cup 14 made of flexible material can fit well with the car box. The suction force is adjusted by the vacuum pump 12 to prevent the problem of insufficient power of the driving vehicle 15. The isolation net made of magnetic material can prevent external goods from being sucked into the suction cup 14. At the same time, magnetic adsorption is used to make the suction cup 14 fit with the car box, reducing the output power consumption of the vacuum pump 12.

[0035] The end surfaces of the reduction motor 6 and the connecting platform 3 are both rotatably connected with a plurality of metal balls, one end of the driving vehicle 15 is connected with a traction rope 23, and the end of the traction rope 23 is connected with a winding box 24 for winding and releasing the traction rope 23; During operation, the reduction motor 6 and the connecting platform 3 will contact the vehicle body. In order to reduce friction, a metal ball and the inner wall of the vehicle body are used for rolling friction. A drive motor 2 is provided in the winding box 24. The rotation of the drive motor 2 can reel in or release the traction rope 23. The reeling traction rope 23 is used to provide a huge pulling force to the driving vehicle 15 and the equipment. When encountering larger cargo, the traction rope 23 can be used to increase the power of the equipment. The winding box 24 can be temporarily fixed on the outside of the vehicle body.

[0036] The support arm 2 is divided into multiple sections, and adjacent sections of the support arm 2 are connected by sleeves 16, and the support arm 2 is fixedly connected to the support arm 2 by bolts; During operation, the sizes of the carriages used for transportation are generally the same. After the equipment is adjusted, it can be used normally. When encountering a carriage that is larger in size, the distance that the support arm 2 slides out of the sleeve 16 can be adjusted to ensure that the driving vehicles 15 at both ends fit the inner wall of the carriage, thereby increasing the applicability of the equipment. At the same time, during daily use, the overall length of the support arm 2 can also be fine-tuned to ensure that the support arm 2 can be firmly hung in the carriage.

[0037] During operation, through the setting of the material-grabbing arm 7, after the truck stops, the two driving vehicles 15 are attached to the inner wall of the truck, so that the slide bar 4 is horizontally propped up, and multiple material-grabbing arms 7 are vertically arranged in the storage space of the truck. The upper force arm 8 and the lower force arm 11 can be controlled to bend by pulling the steel cable 9. The bent material-grabbing arm 7 is located at the top, and then the material-grabbing arm 7 is driven to move to the depth of the truck through the movement of the driving vehicle 15, and then the material-grabbing arm 7 is lowered to return to the vertical shape. The bottom of the vertical material-grabbing arm 7 is flush with the bottom surface of the truck. At this time, the driving vehicle 15 drives the slide bar 4 and multiple material-grabbing arms 7 to move toward the exit, so that the goods can be continuously pushed out of the truck. It only needs to be used outside the truck. The conveyor belt or forklift pallet combination can receive the goods. During the assembly stage of the equipment and the truck, the material-grabbing arm 7 is folded, and the two driving vehicles 15 can be placed at the lower position of the truck storage space. The driving wheels of the driving vehicle 15 can rotate at will, so that the driving vehicle 15 can move arbitrarily on the inner wall of the truck. When the driving vehicle 15 drives the material-grabbing arm 7 to move upward and top, the material-grabbing arm 7 is controlled to move along the direction of the truck. This arrangement facilitates the assembly and disassembly process of the equipment and the truck; through this arrangement, the function of mechanized handling of goods is realized, and the vertical material-grabbing arm 7 can push logistics goods of various shapes, and the efficiency of pushing goods in batches is higher than that of manual handling. Through the setting of the suction cup 14, when encountering goods that are stacked too high, the picking arm 7 is bent. At this time, the suction cup 14 at the end of the picking arm 7 is set horizontally and faces the goods. The driving vehicle 15 drives the suction cup 14 and the picking arm 7 to approach the top of the stacked goods, and the vacuum pump 12 is started to generate negative pressure, so that the goods are sucked. Then the driving vehicle 15 controls the entire picking arm 7 to move horizontally, and the goods are dragged outward from the top of the stack. After that, the picking arm 7 is unbent and becomes vertical, and the negative pressure is turned off. In this way, part of the goods can be separated outward and the height of the stacked goods can be reduced. When the height is reduced to a certain extent, the entire device can be moved to the rear of the goods. The cargo is pushed toward the exit as a whole, thereby effectively realizing the function of transferring the cargo in the truck outward, and can deal with the problem of cargo being stacked too high and having no fulcrum. At the same time, when the picking arm 7 is in a vertical state, the vacuum pump 12 is started to generate negative pressure at the bottom of the suction cup 14, thereby pulling the picking arm 7 to become straight. At the same time, under the action of the negative pressure, the lower force arm 11 will be sucked with the bottom surface of the vehicle box, and the upper force arm 8 above will be restricted and cannot rotate in the opposite direction to the exit. In this way, during the movement of the picking arm 7, the upper force arm 8 above remains vertical, and the lower force arm 11 below will be slightly bent. However, due to the existence of negative pressure, the lower force arm 11 fits with the bottom surface of the vehicle box, thereby effectively pushing the cargo to move toward the exit. If the width of multiple lower force arms 11 is the same as the inner width of the truck, it will be difficult to observe the state of the goods at the rear during operation, which is not conducive to operation. In addition, the mass of the material-grabbing arm 7 is too large, which will also cause the burden of the driving vehicles 15 on both sides to be too heavy. By reducing the volume of the material-grabbing arm 7, the lower force arm 11 is made into a forked shape, and the squeezing net 22 is in a straight state. In this way, as the material-grabbing arm 7 moves, the goods can be pushed to the exit, and the situation of the entire truck box can be observed all the time, reducing operational errors. At the same time, the forked bottom of the lower force arm 11 allows the forked arm 13 of the lower force arm 11 to fully fit with the inner wall of the box, and the upper parts are not used for fitting with the box, which can reduce friction, so that the power is used to push the goods. The slide bar 4 and the support arm 2 are sleeved by the moving platform 20, and the support arm 2 is connected to the driving vehicle 15, and the driving vehicle 15 is against the inner wall of the vehicle box, so as to control the movement of the multiple material taking arms 7; The screw rod 5 is driven to rotate by the reduction motor 6, so that the multiple material taking arms 7 can be moved horizontally, so that a large amount of goods can be pushed out of the vehicle box by controlling a small number of material taking arms 7. For example, the goods on the left side are pushed out first, and then the material taking arms 7 are controlled to move to the right by the reduction motor 6 to push the goods on the right side out; The steel cable 9 passes through the upper lever arm 8 and the lower lever arm 11. The position where the steel cable 9 passes through the upper lever arm 8 is in the middle of the upper lever arm 8, and the position where the steel cable 9 and the lower lever arm 11 are fixed is also in the middle. As the winding roller reels the steel cable 9, the reeled steel cable 9 will first rotate and bend the lower lever arm 11 upward, and then the upper lever arm 8 rotates. The upper lever arm 8 is restricted to rotate only to a horizontal state. The final form is that the upper lever arm 8 and the lower lever arm 11 are stacked on each other and maintained in a horizontal state. At this time, the fixed position of the steel cable 9 and the lower lever arm 11 coincides with the position where the steel cable 9 passes through the upper lever arm 8, which is conducive to the horizontal movement of the equipment on the top of the inner side of the car box without being blocked by the goods. The edges of the extension tube 18 are all set with smooth transitions to ensure that the insertion position of the steel cable 9 will not change. At the same time, the two ends of the extension tube 18 extend outward to reduce the contact between the steel cable 9 and the surface of the material taking arm 7. If the steel cable 9 directly passes through the material taking arm 7, it will cause the steel cable 9 to be close to the surface of the material taking arm 7, which can reduce the wear of the steel cable 9 and the material taking arm 7. The suction cup 14 fits well with the bottom surface of the car box. The bottom surface of the traditional car box cannot be flat. The suction cup 14 made of flexible material can fit well with the car box. The suction force is adjusted by the vacuum pump 12 to prevent the problem of insufficient power of the driving vehicle 15. The isolation net made of magnetic material can prevent external goods from being sucked into the suction cup 14. At the same time, the suction cup 14 and the car box are fit together by magnetic adsorption, reducing the output power consumption of the vacuum pump 12. The reduction motor 6 and the connecting platform 3 will contact the carriage. In order to reduce friction, a metal ball and the inner wall of the carriage are used for rolling friction. The winding box 24 is provided with a driving motor 2. The rotation of the driving motor 2 can wind up or release the traction rope 23. The winding traction rope 23 is used to provide a huge pulling force to the driving vehicle 15 and the equipment. When encountering larger goods, the traction rope 23 can be used to increase the power of the equipment. The winding box 24 can be temporarily fixed on the outside of the carriage. The sizes of trucks used for materials are generally the same. After the equipment is adjusted, it can be used normally. When encountering a truck that is larger in size, the distance that the support arm 2 slides out of the sleeve 16 can be adjusted to ensure that the driving vehicles 15 at both ends fit the inner wall of the vehicle box, thereby improving the applicability of the equipment. At the same time, during daily use, the overall length of the support arm 2 can also be fine-tuned to ensure that the support arm 2 can be firmly hung in the vehicle box.
