Description

Technical Field

[0001] This utility model relates to the field of waste electronic product recycling technology, and in particular to a loading platform with damping speed reduction function at the end of a ramp. Background Technology

[0002] The main purpose of using a loading dock with a damping speed reduction function at the end of the ramp is to improve the safety and stability of the loading and unloading process. When the goods slide down the ramp, if there is no damping design at the end, the inertia will generate a large impact force, causing the goods to tip over, collide or break. The damping speed reduction function can gradually slow down the sliding speed of the goods through the buffer device to avoid accidents caused by excessive speed.

[0003] A search revealed Chinese Patent Publication No. CN219708553U, which discloses a road freight transport unloading platform. The platform includes a chassis device for fixed support and movement, a support device on top for load-bearing and adjusting the unloading angle, and a ramp device on top of the support device for connecting the truck and supporting cargo transport. An extension device is provided on one side of the ramp device to reduce unloading difficulty. This utility model's road freight transport unloading platform utilizes a hydraulic cylinder to raise one side of the unloading plate, making the unloading ramp gentler and reducing unloading difficulty. The extension plate, sliding along the unloading plate, extends the unloading ramp, making unloading more convenient and faster. The extension plate's contact with the ground allows for friction to lock the device head, preventing slippage and ensuring the device's movement doesn't affect unloading.

[0004] In the prior art, a loading dock with damping and speed reduction function at the end of a ramp will cause the speed of the goods to gradually increase due to inertia when the goods slide down the ramp. This will cause the goods to collide with the loading dock and cause damage. Furthermore, rapid discharge will cause the goods to pile up, resulting in the problem of operators being injured when handling the goods. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a loading platform with damping and speed reduction function at the end of a ramp, which aims to solve the problem in the prior art where, when goods slide down a ramp, the speed of unloading gradually increases due to inertia, causing the goods to collide with the loading platform and cause damage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a loading platform with damping and speed reduction function at the end of a ramp, comprising a fixed plate, a motor fixedly connected to the outer wall of the fixed plate, a turntable fixedly installed at the output end of the motor, the outer wall of the turntable rotatably connected to the inner wall of the fixed plate, an intermittent block rotatably connected to the outer wall of the turntable, a rotating block fixedly connected to the inner wall of the intermittent block, the outer wall of the rotating block rotatably connected to the inner wall of the fixed plate, a locking block engaged with the outer wall of the intermittent block, a spring fixedly connected to the outer wall of the locking block, the outer wall of the spring fixedly disposed on the inner wall of the fixed plate, a hollow block fixedly connected to the outer wall of the rotating block, a sliding plate slidably connected to the inner wall of the hollow block, a spring fixedly connected to the outer wall of the sliding plate, the right outer wall of the spring fixedly connected to the inner wall of the hollow block, and a damping component disposed on the inner wall of the hollow block.

[0007] Through the above technical solution: when the goods come down from the ramp body, the starting motor drives the turntable to rotate on the inner wall of the fixed plate. The turntable will intermittently drive the intermittent block to rotate, thereby causing the intermittent block to drive the turntable to rotate on the inner wall of the fixed plate. When the turntable is parallel to the ramp body, the hollow block fixed on the upper surface of the turntable will drive the speed reducer to slide synchronously. The spring installed on the inner wall of the hollow block will push the slide plate to slide, thereby allowing the slide plate to push the speed reducer to slide through the bolt, which can achieve a stable deceleration and buffering effect. When the turntable is perpendicular to the ramp body, the turntable will block the goods, thereby preventing the goods from falling continuously and causing damage to the goods and internal parts. When the intermittent block stops rotating, the spring will push the locking block to lock the intermittent block, which can achieve a self-locking effect.

[0008] As a further description of the above technical solution:

[0009] The damping assembly includes a speed reduction plate, the outer wall of which is slidably connected to the inner wall of the hollow block, a bolt is threadedly connected to the inner wall of the speed reduction plate, the outer wall of the bolt is rotatably connected to the inner wall of the sliding plate, and a support assembly is provided on the outer wall of the rotating block.

[0010] The above technical solution involves a speed reducer that drives a bolt to slide, which in turn causes a sliding plate to slide against the inner wall of the hollow block. This prevents the speed reducer from falling off. By rotating the bolt, the speed reducer can be slid, thereby adjusting the distance between the sliding plate and the speed reducer, which allows for rapid adjustment of the impact resistance.

[0011] As a further description of the above technical solution:

[0012] The support assembly includes a ramp body, the inner wall of which is rotatably connected to the outer wall of the rotating block, the outer wall of which is fixedly connected to the outer wall of the fixed plate, a loading platform body on the outer wall of the ramp body, two sets of support columns fixedly connected to the upper surface of the loading platform body, a second lifting platform slidably connected to the outer wall of the support columns, the right outer wall of the ramp body being disposed on the outer wall of the second lifting platform, a first lifting platform slidably connected to the outer wall of the loading platform body, and a switching assembly on the inner wall of the loading platform body.

[0013] The above technical solution allows for rapid adjustment of the height on both sides by sliding the first lifting platform on the outer wall of the unloading platform body and the second lifting platform on the outer wall of the support column, with the support column fixed to the upper surface of the unloading platform body. The second lifting platform drives the ramp body to rotate on the outer wall of the unloading platform body, allowing the ramp body to adjust its angle while preventing it from falling off. The fixed plate is fixed to the outer wall of the ramp body, ensuring that the rotating block remains balanced with the ramp body at all times.

[0014] As a further description of the above technical solution:

[0015] The switching component includes a second motor. The outer wall of the second motor is fixedly connected to the inner wall of the unloading platform body. A worm gear is fixedly installed at the output end of the second motor. A worm wheel is meshed with the tooth end of the worm gear. A hollow column is fixedly connected to the inner wall of the worm wheel. An adjusting block is snapped into the inner wall of the hollow column.

[0016] The above technical solution involves starting a second motor fixed to the inner wall of the unloading platform to drive the worm gear to rotate. This causes the second motor to drive the worm gear to rotate synchronously, and the worm gear to drive the worm wheel to rotate further. This allows the worm wheel to drive the hollow column to rotate, achieving the effect of precisely adjusting the height of the second lifting platform and the first lifting platform.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the adjusting block is provided with a connecting rod, the outer wall of the connecting rod is slidably connected to the inner wall of the unloading platform body, the inner wall of the unloading platform body is fixedly connected with an electric push rod, the output end of the electric push rod is fixedly set on the outer wall of the connecting rod, the inner wall of the adjusting block is slidably connected with a fixing rod, and the outer wall of the fixing rod is provided with a self-locking component.

[0019] The above technical solution involves activating an electric push rod fixed to the inner wall of the unloading platform body to slide the connecting rod. This causes the connecting rod to drive the adjusting block to slide synchronously on the adjusting block. As one adjusting block is engaged with the hollow column and rotates, the other adjusting block will disengage from the hollow column, achieving a rapid switching effect. By rotating the adjusting block on the outer wall of the fixed rod and the fixed rod on the inner wall of the unloading platform body, the adjusting block can achieve a stable rotation effect.

[0020] As a further description of the above technical solution:

[0021] The self-locking assembly includes a limiting block. The outer wall of the right limiting block is fixedly connected to the outer wall of the fixing rod. A drive shaft is fixedly connected to the outer wall of the left limiting block. The inner wall of the drive shaft is rotatably connected to the outer wall of the fixing rod. The inner wall of the drive shaft is slidably connected to the outer wall of the adjusting block. The inner wall of the adjusting block is slidably connected to the outer wall of the limiting block. The outer wall of the drive shaft is rotatably connected to the inner wall of the unloading platform body. A connecting block is fixedly connected to the outer wall of the fixing rod.

[0022] The above technical solution achieves stable transmission by having the drive shaft and connecting block rotate on the inner wall of the unloading platform body, while the connecting block is fixed on the outer wall of the fixing rod. The left adjustment block locks the left limit block, which is fixed on the inner wall of the drive shaft, allowing the adjustment block to stably drive the drive shaft to rotate.

[0023] As a further description of the above technical solution:

[0024] The inner wall of the unloading platform body is provided with a spring three, and the outer wall of the spring three is fixedly connected with a clamping block. The outer wall of the clamping block is slidably connected to the inner wall of the unloading platform body. The outer wall of the right clamping block is slidably connected to the outer wall of the fixed rod, and the outer wall of the left clamping block is slidably connected to the outer wall of the left adjusting block. The tooth end of the fixed rod is meshed with a bevel gear, and the tooth end of the transmission shaft is meshed with the tooth end of the bevel gear.

[0025] Through the above technical solution: when the right adjustment block is locked to the right limit block, the right adjustment block will slide to the inner wall of the connecting block, which can make the right adjustment block achieve the effect of stably driving the fixed rod to rotate. Through the clamping block installed on the inner wall of the unloading platform body, when the transmission shaft rotates, the spring three will push the right clamping block to lock the fixed rod. When the fixed rod rotates, the spring three will push the left clamping block to lock the left adjustment block, which can make the other side achieve a self-locking effect when one side rotates.

[0026] As a further description of the above technical solution:

[0027] A threaded rod is fixedly connected to the inner wall of the bevel gear, and a lifting rod is threadedly connected to the outer wall of the threaded rod. The upper surface of the lifting rod on the right side is fixedly connected to the inner wall of the second lifting platform, and the upper surface of the lifting rod on the left side is fixedly connected to the lower surface of the first lifting platform.

[0028] The above technical solution involves fixing lifting rods to the lower surfaces of the second and first lifting platforms, respectively. The lifting rods rotate via threaded rods to achieve the lifting effect. The transmission shaft and fixed rod control the rotation of bevel gears, which in turn drive the threaded rods to rotate, thus enabling rapid control of the lifting of the second and first lifting platforms.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the starting motor drives the turntable to rotate while simultaneously driving the intermittent block to rotate synchronously. The intermittent block drives the rotating block to rotate, and the rotating block drives the hollow block to rotate. Multiple sets of springs installed on the inner wall of the hollow block push the sliding plate to slide, which in turn pushes the speed reduction plate to slide. The hollow block can stably slow down and buffer the falling goods, thereby preventing the goods from colliding with the ramp body. Furthermore, the intermittent feeding can prevent the goods from piling up, thus preventing the goods from injuring the operators.

[0031] 2. In this utility model, when the electric push rod is started, it pushes the connecting rod to slide while the adjusting block slides on the inner wall of the hollow column. The starting motor will drive the worm gear to rotate, and the worm wheel will drive the hollow column to rotate, thereby causing the adjusting block to drive the transmission shaft and the fixed rod to rotate respectively. The fixed rod can quickly switch the control of the height on both sides to achieve the effect of unloading materials for different trucks. Attached Figure Description

[0039] 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.

[0040] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a loading platform with damping and speed reduction function at the end of a ramp, comprising a fixed plate 1, a motor 11 fixedly connected to the outer wall of the fixed plate 1, a turntable 12 fixedly mounted at the output end of the motor 11, the outer wall of the turntable 12 rotatably connected to the inner wall of the fixed plate 1, an intermittent block 13 rotatably connected to the outer wall of the turntable 12, a rotating block 16 fixedly connected to the inner wall of the intermittent block 13, the outer wall of the rotating block 16 rotatably connected to the inner wall of the fixed plate 1, a locking block 14 engaged with the outer wall of the intermittent block 13, and a spring 15 fixedly connected to the outer wall of the locking block 14. A hollow block 17 is fixedly connected to the outer wall of the rotating block 16, and a sliding plate 18 is slidably connected to the inner wall of the hollow block 17. A spring 19 is fixedly connected to the outer wall of the sliding plate 18. The right outer wall of the spring 19 is fixedly connected to the inner wall of the hollow block 17. A damping assembly 2 is provided on the inner wall of the hollow block 17. The damping assembly 2 includes a speed reduction plate 21. The outer wall of the speed reduction plate 21 is slidably connected to the inner wall of the hollow block 17. A bolt 22 is threadedly connected to the inner wall of the speed reduction plate 21. The outer wall of the bolt 22 is rotatably connected to the inner wall of the sliding plate 18. A support assembly 3 is provided on the outer wall of the rotating block 16.

[0041] Specifically, the motor 11, fixed to the outer wall of the fixed disk 1, drives the turntable 12 to rotate on the inner wall of the fixed disk 1. When the turntable 12 rotates to the appropriate position, it locks the intermittent block 13, causing the intermittent block 13 to drive the rotating block 16 to rotate on the inner wall of the fixed disk 1. This ensures stable rotation of the rotating block 16 while preventing it from falling off. When the intermittent block 13 rotates to the appropriate position, the spring 15, fixed to the inner wall of the fixed disk 1, pushes the locking block 14 to lock the intermittent block 13, achieving a self-locking effect. The rotating block 16 drives the hollow block 17 to rotate synchronously, and the hollow block 17 drives the sliding plate 18 to rotate synchronously. The rotating slide plate 18 and the speed reducer 21 are connected by bolts 22, which allows the hollow block 17 and the slide plate 18 to drive the speed reducer 21 to achieve a stable rotation effect. Multiple sets of hollow blocks 17 installed on the inner wall of the hollow block 17 are connected to the slide plate 18, which allows the speed reducer 21 to achieve a quick reset and buffering effect. By rotating the bolts 22, the buffering force of the speed reducer 21 can be quickly adjusted. The speed reducer 21 can stably slow down and buffer the falling goods, thereby preventing the goods from colliding with the ramp body 31. Intermittent feeding can also prevent the goods from piling up, thereby preventing the goods from injuring the operators.

[0042] Reference Figure 1 and Figure 3 The support component 3 includes a ramp body 31, the inner wall of the ramp body 31 is rotatably connected to the outer wall of the rotating block 16, the outer wall of the ramp body 31 is fixedly connected to the outer wall of the fixed plate 1, the outer wall of the ramp body 31 is provided with a loading platform body 32, the upper surface of the loading platform body 32 is fixedly connected with two sets of support columns 35, the outer wall of the support columns 35 is slidably connected with a second lifting platform 34, the right outer wall of the ramp body 31 is provided with the outer wall of the second lifting platform 34, the outer wall of the loading platform body 32 is slidably connected with a first lifting platform 33, and the inner wall of the loading platform body 32 is provided with a switching component 4.

[0043] Specifically, by fixing the fixed plate 1 to the outer wall of the ramp body 31, and rotating the block 16 to the inner wall of the ramp body 31, the ramp body 31 can be adjusted at an angle while the deceleration plate 21 remains parallel to the ramp body 31. By installing the ramp body 31 to the outer wall of the unloading platform body 32, the ramp body 31 can be prevented from falling off. The first lifting platform 33 slides on the inner wall of the unloading platform body 32, and the second lifting platform 34 slides on the outer wall of the support column 35. The support column 35 is fixed to the upper surface of the second lifting platform 34, which can prevent the first lifting platform 33 and the second lifting platform 34 from falling off.

[0044] Reference Figure 1 , Figure 3 and Figure 4The switching component 4 includes a second motor 41. The outer wall of the second motor 41 is fixedly connected to the inner wall of the unloading platform body 32. A worm gear 42 is fixedly installed at the output end of the second motor 41. A worm wheel 43 is meshed with the tooth end of the worm gear 42. A hollow column 44 is fixedly connected to the inner wall of the worm wheel 43. An adjusting block 45 is snapped into the inner wall of the hollow column 44. A connecting rod 47 is installed on the outer wall of the adjusting block 45. The outer wall of the connecting rod 47 is slidably connected to the inner wall of the unloading platform body 32. An electric push rod 46 is fixedly connected to the inner wall of the unloading platform body 32. The output end of the electric push rod 46 is fixedly installed on the outer wall of the connecting rod 47. A fixing rod 48 is slidably connected to the inner wall of the adjusting block 45. A self-locking component 5 is installed on the outer wall of the fixing rod 48.

[0045] Specifically, starting the motor 41 fixed to the inner wall of the unloading platform body 32 drives the worm gear 42 to rotate, causing the worm gear 42 to drive the worm wheel 43 to rotate simultaneously, which in turn drives the hollow column 44 to rotate synchronously, enabling the hollow column 44 to achieve a stable rotation effect. By starting the electric push rod 46 fixed to the inner wall of the unloading platform body 32, the connecting rod 47 is pushed to slide, causing the connecting rod 47 to drive the adjusting block 45 to slide synchronously on the inner wall of the hollow column 44. When one adjusting block 45 is stuck on the hollow column 44, the other adjusting block 45 will disengage from the hollow column 44, achieving a stable switching effect. By the adjusting block 45 sliding on the outer wall of the fixed rod 48, while the fixed rod 48 rotates on the inner wall of the unloading platform body 32, the adjusting block 45 can achieve a stable rotation effect.

[0046] Reference Figure 4 and Figure 5 The self-locking assembly 5 includes a limiting block 51. The outer wall of the right limiting block 51 is fixedly connected to the outer wall of the fixing rod 48. A drive shaft 52 is fixedly connected to the outer wall of the left limiting block 51. The inner wall of the drive shaft 52 is rotatably connected to the outer wall of the fixing rod 48. The inner wall of the drive shaft 52 is slidably connected to the outer wall of the adjusting block 45. The inner wall of the adjusting block 45 is slidably connected to the outer wall of the limiting block 51. The outer wall of the drive shaft 52 is rotatably connected to the inner wall of the unloading platform body 32. A connecting block 55 is fixedly connected to the outer wall of the fixing rod 48. A spring 54 is provided on the inner wall of the unloading platform body 32. A clamping block 53 is fixedly connected to the outer wall of the spring 54. The outer wall of the clamping block 53 is slidably connected to the inner wall of the unloading platform body 32. The outer wall of the right clamping block 53 is slidably connected to the outer wall of the fixed rod 48. The outer wall of the left clamping block 53 is slidably connected to the outer wall of the left adjusting block 45. The tooth end of the fixed rod 48 is meshed with a bevel gear 56. The tooth end of the transmission shaft 52 is meshed with the tooth end of the bevel gear 56. The inner wall of the bevel gear 56 is fixedly connected to a threaded rod 57. The outer wall of the threaded rod 57 is threadedly connected to a lifting rod 58. The upper surface of the right lifting rod 58 is fixedly connected to the inner wall of the second lifting platform 34. The upper surface of the left lifting rod 58 is fixedly connected to the lower surface of the first lifting platform 33.

[0047] Specifically, when the left adjusting block 45 locks the hollow column 44, the connecting rod 47 pushes the left clamping block 53 to slide to the inner wall of the unloading platform body 32 and compresses the left spring 3 54, allowing the left adjusting block 45 to quickly release its self-locking effect. At the same time, the right spring 3 54 pushes the clamping block 53 to lock the fixing rod 48, preventing the fixing rod 48 from rotating. At this time, the left adjusting block 45 locks the left limiting block 51, which is fixed to the inner wall of the transmission shaft 52. The transmission shaft 52 rotates on the outer wall of the fixing rod 48, thus allowing the adjusting block 45 to stably drive the transmission shaft 52 to rotate. The transmission shaft 52 drives the bevel gear 56 to rotate, causing the bevel gear 56 to rotate. 6 drives the threaded rod 57 to push the lifting rod 58 to slide, thereby enabling the first lifting platform 33 to achieve a stable lifting effect. When the right adjustment block 45 is locked by the right limit block 51, the right clamping block 53 will disengage from the fixed rod 48, and the left clamping block 53 will lock the adjustment block 45, which can prevent the fixed rod 48 from rotating. By sliding the right adjustment block 45 on the inner wall of the connecting block 55, the right adjustment block 45 can stably drive the fixed rod 48 to rotate, thereby enabling the fixed rod 48 to drive the lifting rod 58 to rise and fall, which can stably drive the second lifting platform 34 to rise and fall. The fixed rod 48 can quickly switch the control of the height on both sides to adapt to different trucks for unloading.

[0048] Working principle: When the unloading platform is needed, the motor 41 drives the worm gear 42 to rotate, which in turn drives the worm wheel 43 to rotate synchronously. The worm wheel 43 drives the hollow column 44 to rotate, and the adjusting block 45 is locked in the inner wall of the hollow column 44, which allows the adjusting block 45 to rotate stably. When the height of the second lifting platform 34 is adjusted, the electric push rod 46 fixed in the inner wall of the unloading platform body 32 is activated to pull the connecting rod 47 to slide, so that the right adjusting block 45 is locked in the limit block 51 and slides to the inner wall of the connecting block 55, which can achieve the effect of stably driving the fixed rod 48 to rotate. The fixed rod 48 drives the threaded rod 57 fixed in the inner wall of the bevel gear 56 to rotate, which allows the lifting rod 58 to drive the second lifting platform 34 to slide on the outer wall of the support column 35 to achieve the effect of lifting.

[0049] When the first lifting platform 33 is raised or lowered, the connecting rod 47 is pushed so that the left adjusting block 45 locks the left limiting block 51, and the spring 3 54 will drive the clamping block 53 to lock the fixing rod 48, thereby preventing the second lifting platform 34 from falling off. The left adjusting block 45 drives the left limiting block 51 to rotate, which in turn drives the transmission shaft 52 to rotate, so that the transmission shaft 52 drives the lifting rod 58 to rise or fall, thereby achieving the effect of stably adjusting the height of the first lifting platform 33.

[0050] When goods are placed on the upper surface of the ramp body 31, the motor 11 is started to drive the turntable 12 to rotate. The turntable 12 intermittently drives the intermittent block 13 to rotate, and the intermittent block 13 drives the rotating block 16 to rotate on the inner wall of the fixed plate 1, which can achieve the effect of preventing it from falling off. The rotating block 16 drives the hollow block 17 to rotate, and the hollow block 17 drives the speed reduction plate 21 to rotate synchronously. The speed reduction plate 21 is connected to the sliding plate 18 by bolts 22, and the sliding plate 18 slides on the inner wall of the hollow block 17, which can achieve the effect of preventing the speed reduction plate 21 from falling off. By compressing the spring 19 on the inner wall of the hollow block 17 by the sliding plate 18, the falling goods can be slowed down and buffered. By pushing the locking block 14 to slide on the outer wall of the intermittent block 13 by the spring 15, a quick self-locking effect can be achieved. This unloading platform can not only stably slow down and buffer the falling goods to prevent them from colliding with the ramp body 31, but also prevent the goods from piling up and injuring the operators by intermittent feeding. It can also quickly switch the height of the two sides to adapt to different trucks for feeding.
