Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of forklifts, and in particular to a fast-moving, anti-fall forklift used in intelligent warehouses. Background Art
[0002] A forklift refers to a variety of wheeled handling vehicles used for loading, unloading, stacking and short-distance transportation of palletized cargo. The structural characteristics and working performance of the forklift are indicated by technical parameters such as rated lifting capacity, load center distance, and mast inclination angle. It is usually divided into internal combustion forklifts and electric forklifts. It is currently widely used in ports, stations, airports, freight yards, factory workshops, warehouses, circulation centers and distribution centers, etc. It can also enter ship cabins, carriages and containers to load, unload and transport palletized cargo. It is an indispensable equipment in pallet transportation and container transportation.
[0003] In existing smart warehouses, goods need to be transported by forklifts. When a forklift transports goods, the forklift's pallet will hold and lift the goods, and then transport them to the designated location with the vehicle body. When the vehicle body moves, the goods will tend to move on the pallet surface under the action of inertia. When the vehicle body's speed is too high, the inertia force exerted on the goods is too large, causing the goods to slide on the pallet surface, which can easily cause the goods to fall off, which is not conducive to the handling of goods.

[0014] (3) Beneficial effects
[0015] Compared with the existing technology, the present invention provides a fast-moving anti-fall forklift for use in intelligent warehouses, which has the following beneficial effects:
[0016] 1. The fast-moving anti-fall forklift used in intelligent warehousing cooperates with the support plate and the anti-fall mechanism. When transporting goods, the goods will be placed on the surface of the support plate. When the vehicle body drives the lifting plate to move, the goods will have inertia force on the surface of the support plate. When the inertia force of the goods points to the outside of the support plate, the transition plate inside the anti-fall mechanism will prop up the right side of the support plate, causing the support plate to tilt inside the deflection groove. The support plate rotates through the support roller, squeezing the deformable support rod made of rubber on the left side. Therefore, the support plate drives the goods on its surface to tilt inward. The gravity deflection force caused by the tilt of the goods will offset the inertia force, thereby achieving the effect of automatically preventing the goods from falling off due to inertia when transporting goods by forklift.
[0017] 2. The fast-moving anti-drop forklift used in intelligent warehousing cooperates with the gear ring and the adjustment mechanism. When the gear ring engages and climbs on the surface of the gear plate, the gear ring will be blocked at a specific position by the extrusion frame. This is because the lower limit spring pulls it through the limit rod, so that the deflection angle of the support plate cannot be changed. At this time, since the left side of the connecting rod is fixedly connected to the extrusion block and is not fixed to the slider, the connecting rod will move with the extrusion block and squeeze the slider, causing the slider to further compress the limit spring on the right. Therefore, the slider will drive the gear ring to move further through the limit rod, and the moving distance will increase with the increase of inertia force. Therefore, the deflection angle of the support plate will change with the change of inertia force, thereby achieving the effect of automatically adjusting the deflection angle of the support plate according to the magnitude of the inertia force, thereby preventing the goods from sliding on the surface of the support plate.

A driving wheel 611 is provided inside the air-filled chamber 610. The driving wheel 611 is rotatably connected to the wheel ring 616 through an elastic belt. The lower part of the driving wheel 611 is rotatably connected to the wheel ring 616 through an elastic belt. The surface of the wheel ring 616 is fixedly connected to the driven wheel 617. A circular protrusion is provided on the side of the driven wheel 617, and is initially aligned with the force block 616. 8 There is no extrusion pressure contact. As the driven wheel 617 rotates, the force block 618 will be squeezed and drive the gear ring 612 to rotate. The side of the driven wheel 617 is slidably connected with the force block 618. The side of the force block 618 is provided with a gear ring 612 through a spring. The bottom of the gear ring 612 is meshed and connected with a tooth plate 615. An extrusion frame 613 is provided on the right side of the gear ring 612. The right side of the extrusion frame 613 is fixedly connected with an inflatable plate 614. The anti-fall-off mechanism 6 is provided with an adjustment mechanism 7 inside.
[0026] When transporting goods, the goods will be placed on the surface of the support plate 2. When the vehicle body drives the lifting plate 1 to move, an inertial force will appear on the surface of the support plate 2. When the inertial force of the goods points to the outside of the support plate 2, the goods are in danger of falling off. Therefore, an anti-falling mechanism 6 is provided. When the inertial force of the lifting plate 1 to the right reaches a certain level, the inertia block 603 will slide on the surface of the slide bar 602, and the inertia block 603 can drive the squeezing block 604 on the right to squeeze the pressure-sensitive switch 605. Since the pressure-sensitive switch 605 is connected to the driving wheel 611 and the controller of the motor is connected through an electrical signal, the driving wheel 611 rotates, and the driving wheel 611 is rotatably connected to the wheel ring 616 through an elastic belt. Therefore, the wheel ring 616 will drive the driven wheel 617 to rotate, and the side of the driven wheel 617 is provided with a circular protrusion, and initially there is no squeezing contact with the force-bearing block 618, so As the driven wheel 617 rotates, the force block 618 will drive the gear ring 612 to rotate, causing the gear ring 612 to mesh and crawl on the surface of the tooth plate 615, and then drive the inflation plate 614 to move inside the inflation chamber 610 by squeezing the extrusion frame 613 on the right side. The gas inside the inflation chamber 610 is squeezed through the conduit 609 into the interior of the expansion spring 608, causing the expansion spring 608 to deflect. Therefore, the transition plate 606 will be squeezed to support the right side of the support plate 2, causing the support plate 2 to tilt inside the deflection groove 3. The support plate 2 rotates through the supporting roller 4, squeezing the deformable support rod 5 made of rubber on the left side, so that the support plate 2 drives the goods on its surface to tilt inward. The gravity deflection force caused by the tilt of the goods will offset the inertia force, thereby achieving the effect of automatically preventing the goods from falling off due to inertia when transporting goods by forklift.
[0027] Example 2: Please refer to Figure 1-5 A fast-moving anti-fall forklift for use in intelligent warehousing includes a lifting plate 1, a deflection groove 3 is provided on the top of the lifting plate 1, a support plate 2 is provided inside the deflection groove 3, a support roller 4 is provided at the bottom of the support plate 2, a support rod 5 is rotatably connected to the bottom of the support plate 2 and located on the left side of the support roller 4, an adjustment mechanism 6 is provided inside the lifting plate 1, an inertia cavity 601 is fixedly installed inside the anti-fall mechanism 6, a slide rod 602 is fixedly connected to the inside of the inertia cavity 601, and the slide rod 602 is fixedly connected to the bottom of the support plate 2. The surface is slidably connected with an inertia block 603, and an adjustment mechanism 7 is provided inside the anti-falling mechanism 6. A connecting rod 701 is fixedly installed inside the adjusting mechanism 7. The left side of the connecting rod 701 is fixedly connected to the extrusion block 604 and is not fixed to the slider 702. A slider 702 is provided on the right side of the connecting rod 701. The side of the slider 702 is rotatably connected to the limiting rod 703. The right side of the slider 702 is fixedly connected to the limiting spring 704. The side of the slider 702 is slidably connected to the sliding cavity 705.
[0028] When the gear ring 612 engages and crawls on the surface of the tooth plate 615, the gear ring 612 will be blocked at a specific position by the extrusion frame 613. This is because the lower limit spring 704 pulls it through the limit rod 703, making the deflection angle of the support plate 2 unable to change. At this time, since the left side of the connecting rod 701 is fixedly connected to the extrusion block 604 and is not fixed to the slider 702, the connecting rod 701 will move with the extrusion block 604 and squeeze the slider 702, causing the slider 702 to further compress the limit spring 704 on the right. Therefore, the slider 702 will drive the gear ring 612 to move further through the limit rod 703, and the moving distance will increase with the increase of the inertia force. Therefore, the deflection angle of the support plate 2 will change with the change of the inertia force, thereby achieving the effect of automatically adjusting the deflection angle of the support plate 2 according to the magnitude of the inertia force, thereby preventing the goods from sliding on the surface of the support plate 2.

A clamping rod 607 is provided on the bottom of the transition plate 606 and on both sides of the expansion spring 608.

A driving wheel 611 is provided inside the air-filled cavity 610. The wheel 611 is rotatably connected to the wheel ring 616 through an elastic belt. The lower part of the driving wheel 611 is rotatably connected to the wheel ring 616 through an elastic belt. The surface of the wheel ring 616 is fixedly connected to the driven wheel 617. A circular protrusion is provided on the side of the driven wheel 617, and there is no extrusion contact with the force block 618 at the beginning. As the driven wheel 617 rotates, the force block 618 will be squeezed and drive the gear ring 612 to rotate. The side of the driven wheel 617 is slidably connected to the force block 618. The side of the force block 618 is provided with a gear ring 612 through a spring. The bottom of the gear ring 612 is meshed with a gear. Plate 615, an extrusion frame 613 is provided on the right side of the gear ring 612, and an inflatable plate 614 is fixedly connected to the right side of the extrusion frame 613. An adjustment mechanism 7 is provided inside the anti-falling mechanism 6, and a connecting rod 701 is fixedly installed inside the adjusting mechanism 7. The left side of the connecting rod 701 is fixedly connected to the extrusion block 604 and is not fixed to the slider 702. A slider 702 is provided on the right side of the connecting rod 701. The side of the slider 702 is rotatably connected to the limiting rod 703, the right side of the slider 702 is fixedly connected to the limiting spring 704, and the side of the slider 702 is slidably connected to the sliding cavity 705.
[0030] Working principle: When transporting goods, the goods will be placed on the surface of the support plate 2. When the vehicle body drives the lifting plate 1 to move, an inertial force will appear on the surface of the support plate 2. When the inertial force of the goods points to the outside of the support plate 2, the goods are in danger of falling off, so an anti-falling mechanism 6 is provided. When the inertial force of the lifting plate 1 to the right reaches a certain level, the inertia block 603 will slide on the surface of the slide bar 602, and the inertia block 603 can drive the extrusion block 604 on the right to squeeze the pressure-sensitive switch 605. Since the pressure-sensitive switch 605 is connected to the driving wheel 611 and the controller of the motor is connected through an electrical signal, the driving wheel 611 rotates, and the driving wheel 611 is rotatably connected to the wheel ring 616 through an elastic belt. Therefore, the wheel ring 616 will drive the driven wheel 617 to rotate, and a circular protrusion is provided on the side of the driven wheel 617, and initially there is no extrusion force contact with the force-bearing block 618. As the driven wheel 617 rotates, the force block 618 drives the gear ring 612 to rotate, causing the gear ring 612 to mesh and crawl on the surface of the tooth plate 615, and then drives the inflation plate 614 to move inside the inflation chamber 610 by squeezing the extrusion frame 613 on the right side. The gas inside the inflation chamber 610 is squeezed through the conduit 609 into the interior of the expansion spring 608, causing the expansion spring 608 to deflect. Therefore, the transition plate 606 will be squeezed to support the right side of the support plate 2, causing the support plate 2 to tilt inside the deflection groove 3. The support plate 2 rotates through the supporting roller 4, squeezing the deformable support rod 5 made of rubber on the left side. Therefore, the support plate 2 drives the goods on its surface to tilt inward. The gravity deflection force caused by the tilt of the goods will offset the inertia force, thereby achieving the effect of automatically preventing the goods from falling off due to inertia when transporting goods by forklift.
[0031] When the gear ring 612 engages and crawls on the surface of the tooth plate 615, the gear ring 612 will be blocked at a specific position by the extrusion frame 613. This is because the lower limit spring 704 pulls it through the limit rod 703, making the deflection angle of the support plate 2 unable to change. At this time, since the left side of the connecting rod 701 is fixedly connected to the extrusion block 604 and is not fixed to the slider 702, the connecting rod 701 will move with the extrusion block 604 and squeeze the slider 702, causing the slider 702 to further compress the limit spring 704 on the right. Therefore, the slider 702 will drive the gear ring 612 to move further through the limit rod 703, and the moving distance will increase with the increase of the inertia force. Therefore, the deflection angle of the support plate 2 will change with the change of the inertia force, thereby achieving the effect of automatically adjusting the deflection angle of the support plate 2 according to the magnitude of the inertia force, thereby preventing the goods from sliding on the surface of the support plate 2.
